alright first up okay first up we've got the game do we know dazzler and this is pretty nifty so this is a two-parter basically on the right is a feather wing breakout and on the middle is this gd3x dazzler which has an only get this part number correct this is a Spartan six XC six SLX nine Xilinx FPGA and it's also got the this FTDI you know HDMI driver chip it's got a bunch of RAM and HDMI output basically it says a scripting system that lets lets you very quickly make stuff that connects to HDMI and you can play videos and animations and it's like pretty nifty if you want to have HDMI coming out of your feather and for this is designed specifically for the feather and for it's kind of an all-in-one like video system so I haven't checked this out this is hooked up to an HDMI monitor and this is like the first demo you run so it's got you can load in this bitmap and then you tell it you want it to rotate it so this isn't a gift this is a composite image where it's like it tells it to draw the background and then it tells it to draw all these blinkers and have them animate so it's like you can do quite advanced motion graphics and animations even though the feather and fork can't do it you you have basically this graphics co-processor it's quite powerful there's also an Arduino shield version and I think there's a Pico version of course you can wire it up to a Pico you have to do wiring and stuff but I thought this was so cool there's like video game demos and like animation demos and like I think it can play MP4s or movies just a glimpse of where we're going with like circuit Python like there'll be HDMI output yeah and stuff is what's you know the the the person who James Bowman who did this and what the code he realized if you have a co-processor that's doing all the hard stuff right all the graphic stuff it doesn't matter if the programming language that you're programming that co-processor with is slow because all the high-speed stuff is handled on the FPGA anyways like you don't need to control an FPGA with C control the FPGA with circuit Python it's easier and faster you've got a file system to look you know this is this bitmap is it on the file system of the circuit Python device that parts really easy and then you offload all the graphic stuff to the co-processor very cool so you want to do games on to HDMI output game doing a dazzler next up from M5 stack this is kind of neat somebody requested we got this and we know we'll always carry stuff on request we think it's cool this is an M5 timer camera it's an ESP32 with eight megabytes of PS RAM a camera module and it's nice little clip and what's neat about it is an ultra low-power RTC with a timer so it's really designed to do like ultra low power go to sleep and then wake up take a photo and then send it over Wi-Fi so if you want to make like an outdoor you know or powered you know low power Wi-Fi wake up take a photo send it project this is kind of all-in-one it even has a mounting bracket kind of handy except next up and neopixels our favorite neopixels either 3.5 millimeter or 3.5 millimeter we love these we use them on all sorts of our products such as the neotrinky you see four of them here you see them on many feathers and you're probably like man I wish I had a hundred of them and I wish I had a hundred of them on like a piece of cut tape way we gotcha this is we've stopped these impacts of 10 but if case you ever want to like use these in a small pick-and-place it's less expensive we'll just send you a reel of 100 LEDs you can use them you can kind of hand solder them if you're careful you can use them in reflow just be careful about moisture they're very moisture sensitive okay next up next up we've got usb-c we've been carrying a bunch of connectors these are very low-cost usb-c connectors why are they so low-cost as you look on the bottom you can see they are have fewer pins than normal they only have six pins why because they're power only these do not have data lines we repeat that again they do not have the data lines we have all over the product page a million places these are specifically for power only projects where you want to power something over usb-c and again only over usb-c I think five volts put a five kilo ohm resistor from cc one that's one of the pins to ground another 5k from the other cc two pin to ground and then there's two bus pins two ground pins you got five volts out no data lines but they're really cheap and they're pretty easy to solder because the pads are really big so there are projects that I think could use this other than that they're great connectors just you know I don't know if I mentioned it already but no data lines just power all right next up next up this is a cool long piezo sensor this is kind of interesting so usually piezo sensors come in a square or round you know vibration sensor shape this is these are originally designed to be sleep sensors like they go in a pillow or underneath the mattress and when people move it can detect it so piezo sensors when they're moved they see this fine hand model as this fine model you know gently tweaks or pushes or twists the piezo it generates a very small current between the two metal pins you put a one mega omer system between the pins tie one to ground tie the other to an analog input you can read the analog input and detect touches twists etc and then you can act on it you know in this case it was designed for a sleep sensor data logger that said it's so unusual to find a piezo that comes in this shape it's very long thin flexible shape this can be used for all sorts of sensor applications like wearables I thought or like sports or you know anytime you have a touch sensor it has to go around something or through a thin slot it's just a very unusual shape it makes a little bit more expensive but you know I've never seen anything like before so I think these are quite cool you can cut it down of course but once you've cut it you cannot reattach it because the film is this you can't solder to the film so you've got like the one end and then it kind of goes on for you know 600 millimeters cut it just be where once you cut it you can't uncut it all right next up okay next up we've got a the neopixel with this is a one meter long 60 led neopixel strip and it's got this very beautiful diffused silicone covering which will also show on the overhead in a moment as I get my my demo going these are basically like your everyday normal neopixels power them with five volts give them data on you know one of the pins using any new pixel library but what's cool about them is they've got this very durable and weatherproof soft silicone covering so let me turn it off so I can show you so it looks you can barely see the LED strip through it I mean it's almost more visible on the camera and on the back it's got a nice it's a firm stiff like you can't really bend it this way but it you know it does bend back and forth this way and what's nice about it is a as I mentioned it's it's it's a very nice diffuse effect more so than it's not as much as our neon which is you know really a thick plastic and very hard to bend and it's definitely not as clear as the clear translucent normal neopixel it's diffused and it makes it look kind of pastelly it kind of is a beautiful look so we have really good photos check out the animations because they're they're shot quite nicely but I think if you want something that's durable and weatherproof and and has a little bit of diffusion but still is flexible this is a nice intermediary between the totally clear and of course this the totally diffused neon yeah it's hard to explain but it's like I like the look of it yeah it's really nice it's a very elegant look yeah I mean it's I've known and seen projects that like this is this is the main thing they just wanted to be diffused but they're using yeah it just has a nice clean look to it so I think you know for wearable projects or architectural projects where you you want to be thinner than the neon but it's cool not as not as harsh as the clear neopixels so I like it next up the star of the show tonight besides you lady at our team our community all the customers the books and chat is it's a bit RP 2040 that's right we're gonna put some into the shop a little bit later night after the show because we ran out but I stashed them so put some more in this is the RP 2040 based itzy bitzy so people like the itzy bitzy inspired by teensy boards but I wanted to have them with different chips so it's kind of the same sort of size it's I think 0.7 inch by 1.2 inches bite size but has a lot of GPIO pins the GPIO pins go all the way around I want to show and compare so this is the M0 yeah we're getting there okay so you got the M0 express the M4 the blue fruit and now new friend is made RP 2040 so it's for it's worth it's actually two more the 32 you four ones which I didn't even bring down because these are nice and popular but what I tried to do is I try to make them sort of similar I try to have like the neopixels over here and you know these have the buttons on the end this of course has the antenna here so the buttons have to move up to the itzy bitzy if you want to have a lipo battery of a lipo backpack that you can use with it there's a single-sided board it has an 8 megabyte q-spy flash it has the reset button it has the boot button I did the cute primary hack where the boot button is also a user button after booting so when you're running code you can use this as a single button input it's got a neopixel here I wonder if I still have the neopixel program yeah I do it's got a one red LED for blinking it's got the crystal power supply lots of little capacitors I had to use a 402 components to make everything fit but it did all fit in the end and then on the bottom we have the GPIO pinout so this is if you're using it with pico SDK with your micro python or something where you need to do the raw pin numbers these are labeled on the bottom and then there's one pin d5 that's special purpose and that pin is level shifted up to about five volts so if you want to drive neopixels if you want to five old up but there's some there's some times where people are like I need to to control something that's a five volt input it really wants five volts particularly neopixels that pin is level shifted out to zero to five volts you've got one pin over here it's five it's got the exclamation point to remind you that it's the output pin but otherwise it's what it's nice about the RP2040 is you know it's it's the dual core Cortex M0 it's running at 130 megahertz it's got circuit Python and now Arduino supports coming out micro python support you can do pico SDK and you've got a lot of pins and I made sure that you know you've got not only a lot of pins but get all the analog pins there are eight pins in a row if you want to do like camera projects where you use the PIO to drive eight GPIO at once they're not all in a row because I wanted to match like the SDA and SPI pen and UR and analog pins match the other itsy-bitsies but they are available you can get to all those pins if you want they're just if you look on the bottom I think it's 26 27 28 29 and then 24 25 18 19 20 you know whatever basically you got lots of pins are in a row so if you want to use PIOs to drive many pins in parallel you got it and you know it's nice is that you can swap these between the two you got a project with an M0 and M4 you want Bluetooth swap between it you want RP2040 swap between that as well so you know one of the original RP2040 boards that we said we would design and so we we fulfilled it we got the cutie pie itsy-bitsy and the feather so this is a great tiny board with lots of GPIO pins and if you want you can add a lipo charger onto it by soldering on one of our lipo backpacks and that's your products


I'm here at BITU in Geneva. And I'm very pleased to be joined by Kwame Baachiamfor, Chairman of Study Group 12. Kwame, welcome, and thank you very much indeed for joining us here today. Thank you very much, Fred. Could you please explain to our viewers a little bit about Study Group 12 and also how some of your work is at play in our daily lives? Study Group 12 is the least study group on performance, quality of service, and quality of experience. And also the least study group on car communication and driver distraction. And from WTSA-16, there is a new Study Group rule for Study Group 12, which is an assessment of quality of video communications and audio visuals. So this is intended to ensure that if you look at terminals for users, and you look at network elements which operators use, they have a certain level of performance, then we go into the services of applications, which can be an output of the communications between the networks and the terminals. And with this, what the consumer expects is customer satisfaction. And among the things we lead to customer satisfaction is quality of service and quality of experience. And so which Study Group 12 produces standards, recommendations, and many other guidance on. And it seems recently the group has been doing some work on communications in motor vehicles. Can you please explain what kind of work is taking place there? Yes, transportation and communications have been good friends for many years. And for the ITAU, the interests and the collaboration has been with the automobile industry. To ensure that together, we collaborate to produce subsistence for voice communication in vehicles to enhance safe listening and transportation of persons. We are aware of the dangers of distraction when using the car or the vehicle. And you are communicating at the same time. And as much as possible, the two industries consider that it is important to collaborate to produce a safer means of using both the vehicle and communications at the same time. And the group has also been attracting a lot of participation from developing countries and from regulators as well. What is the group doing to increase collaboration between expertise, experts, and the regulators? And how is this manifesting itself in Study Group meetings? Yes, in the ecosystem of especially performance, quality of service, and quality of experience are the manufacturers who produce the terminals for the users who many of them are in developing countries. And then also, manufacturers produce for network operators, many of whom are spread over developer and developing countries. And then there are various services of interest, even if they are developed in developed countries. They are tended to be used in developing countries. And regulators around the world in some countries tend to be responsible for these quality of service that their consumers enjoy. So in this ecosystem, our Study Group tends to bring everybody together to get an understanding on what the possibilities are, what the provables are, and what the wishes are to ensure especially quality of service and quality of experience for the consumer to use communication systems. And this is a new Study Group period for the next four years. What are some of the hot topics and priorities that are coming up for your group? The world is a sighted where the IMT services and people will talk about 5G coming up in the future. So for us at Study Group 12, it is one of the hot topics to ensure that this new service that people are envisaging comes with the expectation of quality. Again, one of the things which is driving the economies of the world, and especially in developing countries, is digital financial services. And this is also one that could be jeopardized if the quality is not good enough. So these two issues are among the hot topics that we want to focus and ensure that for futuristic services and networks, quality is assured in them. Kwame, I'd like to thank you very much indeed for joining us here today, and also to congratulate you on your re-election as chairman of the Study Group, and wish you a successful four years in the next study period. Thank you very much. It will be a pleasure to be here. Thank you.


What we're doing here is providing clean toilets and transforming waste actually into a fuel that can be used to replace firewood in the camp. Their waste is being collected every three days. We're treating it here at this localized treatment site, actually using solar concentrators that just use the sun's energy to kill off all the pathogens. We're then combining that with some other charcoal dust and other waste and creating an alternative burning fuel to replace the burning needs here in Kakama. The charcoal is actually fantastic. It actually has less carbon monoxide output than normal charcoal. It has less particulate emissions. It actually burns longer. And since you're using two waste products, you're actually helping with deforestation. These drums here are full of human feces and what we're doing with solar treatment is rendering the feces safe to be reused through concentrating the sun's energy and getting the feces to high temperatures that inactivates all the pathogens. Here's our mixture of treated feces with charcoal dust and what we do with this mixture is we press it with our press to make charcoal briquettes. The waste is compacted down. It's nice and squeezed tight. You get a compression that actually produces a handful of briquettes like this.


The particular way of doing interacting problem is what is known as configuration interaction. Again, many of you might have heard this acronym called CI, so this is actually called the configuration interaction. In fact, this is done much after Hartree-Fock normally, see first read Hartree-Fock which is only one electron, one determinant and then you go to this, but this is potentially much simpler to explain because it is very simple mathematics. So what is configuration? Configuration is determinant, interaction is a combination, so that is why it is called a linear combination of determinants or linear combination of configurations and this is called the configuration interaction and very popular quantum chemistry method called CI. Now depending on how I truncate, of course nobody can do all, this CI has different flavors CI SD, CI SD triples, all that we will do later. The point is that mathematically this is an exact form provided my basis is complete. So the question that you are asking the basis is not complete of course, you are right. So this was an example, but if I take that three to be a complete set potentially this is an exact or four to be the complete set potentially it was an exact. So if I have a complete basis that is one and within this complete basis all determinants, remember my basis may be complete, but I may choose that I am not going to take all determinants. I am going to only remove some determinants. So that choice is also there. So there are two levels of approximation, one is the basis, one is the number of determinants. I need not take MCN. Even if M is complete I need not take MCN for some reasons. So I can make approximation in the basis, I can make approximation in the number of determinants. But if you have a complete basis and within that if you take all determinants then this method is called full CI and I think it is obvious. Now full means you have taken all possible determinants in a complete basis. In a complete basis and then the full CI of course in a complete basis is exact. I repeat it that full CI in a complete basis is exact. This is an exact way of function because now there is no more error basis. So that is the problem. So complete basis can never be done because it is infinite. So this is really a statement which has no meaning not relevant because I really cannot do it an infinite dimensional problem. However what is normally practiced is a finite basis. This is a normal practice, finite basis and then I can take all determinants within the finite basic and then this is still called full CI in this basis in the finite basis. The name full CI just means that all determinants have been taken. So as long as you are taking all determinants in a given basis we will call it full CI because anyway in complete basis we will never get. So we will worry about full CI in the finite basis. So whenever we call full CI you have to specify the basis. So even full CI results are different. Remember if I do a problem of Strodinger equation solution full CI the results will be different because your basis is different. If you keep on increasing your basis your number of determinants are more in the full CI and then the results will be different. Of course if you do not take all determinants then again results will be different. So there are lots of approximations we can do. But let us understand that the exact is full CI in a complete basis. So I have complete basis I have all determinants do full CI that is an exact function yes well usually it is infinity. So that is what I am saying it is in practice never implemented that is the different matter. Limit is limit is when you do not find results changing you call it almost saturated. So that is all that is a different matter mathematically maybe the number is changing but it is changing so small that you do not care.  So we will see that how to do the calculation we will see later and the energy does not change. So that will be on Hartree Fogg also full CI everything any CI calculation but right now we do not want to discuss CI I just thought I will tell you the form that a form of an exact wave function is possible that is what I wanted to tell you for an for an interacting Hamiltonian for a non interacting Hamiltonian of course any any one of this determinant is an exact function any one of the determinant is an exact function question is which is ground state which is excited state that is a different matter. So whichever has the lowest energy that can be also seen from the energy of those orbitals so one can find out the now what is important is that once you have understood that the interacting problem is a linear combination of determinant then we have to worry about how do I make good approximation so what is a good approximation is always to take a good basis even though it is finite it is a good basis it includes most of the physical effects of the complete basis and I cannot take all determinants also in many cases so I must take determinants which are physically important. So two levels of approximations that we will do in CI later for interacting problem is that one is the basis another is the number of determinant so the approximations that we will bring in CI is a the basis so what is a good basis so what do you mean by good basis good basis means with a less number of functions I should be able to generate the effects of the complete basis as good as possible so that is why you have to be very good so lot of people have worked on this basis this basis is not only a problem on CI all across quantum chemistry this is a very very important problem. Second is within this basis which determinants are important so if we know these we will only take those important determinants because eventually we cannot do exact calculation we will do approximate calculation so we want to take physically important determinants and not MCN because some of them may not really be important so these are the two very important parts which will define my CI even before that there is a very important question that we understand the value of a single determinant I told you chemistry comes in single determinant because if it is single determinant chemists are very happy you have N electron N spin orbital chemists don't understand all the CI they get confused right they will same confusion will happen with electron coordinate spin orbital what is happening you tell me which electron is in which spin orbital you have to give one answer such an answer is not possible but you have to satisfy an experimentalist right I mean even if you say electrons are indistinguishable okay tell me N spin orbitals N electrons for N electron problem give me N spin orbital so given everything when I am saying which determinant is important the approximation to one very important approximation that we want to do is that can I get one determinant which is very important one means single whenever I am saying determinant please remember it is later determinant which is most important among the single determinant I can have many many single determinant but can I get one of this determinant which is the most important because then at least I can go to the chemistry that determinant not MCN not even not even a partial set of determinant just one so that is the answer that we will get from by Hartree and Fock so this is the answer that we will get and that is will be called Hartree Fock approximation where we are actually going to 0 in only one determinant and not any set of determinant combination of determinants which is the most important so that is a question that I am asking simply because after doing all these mathematics we have to be as simple as possible so before we do better let us go back to the basics and ask the question just like in non-interacting Hamiltonian we had one determinant which was exact in this case of course we cannot get anything exact but can I get one determinant which is as close to exact as possible I hope you understand the question of course it is not exact so when I say most important it must be as close to the exact as possible so this answer is given by Hartree Fock method so I just kind of telling before we start the Hartree Fock there are lot of background work I have to do but I just want to tell physically what is the question that we are asking it is very important to ask the question for an interacting Hamiltonian this is never going to be exact but we are only trying to ask a question can I get a function can I get a determinant which is as close to one determinant which is as close to exact as possible because then I will have a very simple chemist interpretation n electron n spin orbitals so the problem is that for an interacting Hamiltonian which is sum over h of i note again when I write interacting Hamiltonian please remember very simple form I want to get one determinant which is as close to exact as possible of course you can immediately say forget about this make it a non-interacting problem and then I will get one determinant the question is is it as close to exact as possible that I don't know that is certainly one determinant I can easily get by completely neglecting it but that may not be the best determinant because we have no a priori reason to think that is the best determinant so how do I get that determinant will be the content of the Hartree-Fock method so before I start Hartree-Fock I just thought I will tell you I will again come back tomorrow and talk about it I think once the problem statement is clear what are you doing many people after doing Hartree-Fock not sure what are they doing why did they do it that is very important I think I first want all of you to understand what are we doing technical details if you don't means that's okay I don't care but you must know what are you doing what is the question that you're asking so the question that I'm asking is to give the chemist one single determinant even for an interacting problem and and would it be that determinant by simply neglecting this then I have an answer the answer is actually no so that is the reason Hartree and Fock did that's an answer that I can tell before I do it okay so I think we will start with that Hartree-Fock method now but before that there are certain background work that I have to do some little bit of mathematics which is essentially calculating matrix elements of the Hamiltonian I will have some rules later rules I will lay the lay them down because they will all be required and of course the most important thing will be answered by what is called the variation principle so I will again repeat the variation principle I've done it in 4 to 5 I will repeat variation principle some certain mathematical rules for getting the matrix elements before I actually can tackle this question some background work will be done from tomorrow okay so what I hope you have understood the question I think if you have any any problem with the question please ask you know that is most important in fact CI is much more easy it is just mathematics Hartree-Fock is more difficult because it has a physics how do I get the most important physics built in and if you don't ask that question then you will miss the essence of the Hartree-Fock so Hartree-Fock will be eventually very good yet not good enough because it is still a single determinant so so then the question that we will ask how good it is why is it not good enough that we have to do something better in fact the Hartree-Fock was developed in 1933 Hartree and Fock did long back why didn't quantum chemistry stop there you know that's the question so obviously it is not good enough so all those questions we will ask later not today we'll first see how can I do a best single determinant picture and then we'll see how can I improve this on the quantum mechanics the first paper came in this is a Heitler and London did valence bond theory in 27 1927 then Hartree and Fock did in the 30s this is molecular orbital theory okay I think things will become more interesting as you go to the real part so please try to follow and make sure that you ask questions okay I mean he asked a question good question everything was good question I mean everybody was confused the way you said because everybody will think just in change one and two index it is not that it is a coordinate change so it is a good question I would say so please feel free to ask questions that's very important no no it is a good question I mean I don't say anything which is a bad question okay okay thank you


Dear learners, welcome you all to this video which is based on your MFA semester 1st course Unit 12 that is Swami Vivekananda and his educational thoughts. If we look at the learning objective of the unit, after watching the video you will be able to depict the life sketch of Swami Vivekananda, describe the life and philosophy of Swami Vivekananda, explain Vivekananda's educational thoughts. If we look at the life sketch of Swami Vivekananda, then we have seen Swami Vivekananda is a great philosopher, a reformer and he dedicated his whole life for the upliftment of humanity. In fact, he was a great teacher as well as practical saint of modern India. He was born in Bengali Karista family on Monday 12th January 1863 in Kolkata. His real name was Narendra Nath Doctor, his father Bishonath Doctor was a famous lawyer in Kolkata High Court, his mother name was Bhubaneshwari Devi. Vivekananda inherited a religious temperament and farsighted intelligence from his parents. He was deeply interested in the study of philosophy and religion. He studied history, literature and philosophy since very early age. Harvard Spencer and Jace Mill were his favorite philosopher and what sort was his favorite poet. So, if we see his ideology, actually Siri Ramakrishna Paramhansa inspired him to lead the life of a monk and spread the light of Indian philosophy throughout the world. When Siri Ramakrishna Paramhansa died in the year 1876, Swami Vivekananda established Ramakrishna Mission to carry on further the unfinished religious assignment of his guru father. He set out for the Himalayas in 1890 and stayed there for two years. In 1892, he reached Koinakumari and visited the sacred shrine of the goddess and he jumped into the sea and reached a rock. He started meditation there. He didn't went to Chennai when people were very much impressed by his personality. They collected funds to send him to America to participate in the Bistro Dharma Sommelon in September 1893. He introduced to the world Indian religion, culture and philosophy to the world. As a consequence, the unknown monk of India suddenly gained international attention at the parliament of religions held in Chicago in 1893 and as a philosopher, he proved that the ancient philosophy of Vedanta could successfully meet the challenges of today and solve the modern problems very effectively. He was actually the person who synthesized the idealistic philosophy of the West and creative Vedantic philosophy of Hindu religion. He preached universal brotherhood and interpreted humanism in his idealistic manner. He died on July 4, 1902 at the young age of 39 years. If we see the Vivekananda's philosophy, then Vivekananda sexually described God as a supreme power and God is of infinite existence, infinite knowledge and infinite bliss. He is present in man. Vivekananda has a firm faith on different world religions. He thinks that a pre-religion is progressive and has many good points. He advocates that no religion is inferior or superior to another. The goal of all religions is reaching God through spiritualism and brotherhood. The most important or the significant contribution of Swami Vivekananda to the modern world is his interpretation of religion as a universal experience of transcendent reality common to all humanity. The main essence of his philosophy of life to become fearless through struggle and serve humanity with peace. He wanted to develop the individuals who are without fear from enemies, face all the challenges boldly and confidently without any suppression. He firmly believed in the equality of mankind and pressed extensively to remove biases and exploitation based on caste, creed, religion, race and gender. So if we look at the famous quotations regarding fearlessness as Swamiji rightly pointed out that all power is within you, you can do anything and everything. So if we look at Vivekananda's educational thought then we have seen Vivekananda's has been ranked among the greatest educationists of the world. His philosophy of education is based on the permanent truth of Upanishada, Bhagavad Gita and Vedanta. To him education is the manifestation of the perfection already in man. No knowledge comes from the outside, it researches in the human mind, man manifests knowledge and discovers it within himself which already existed there through eternity. If regarding the educational thought according to him, education is not the mass of knowledge or information inserted into the minds of children by force. Real education is dead which prepares a man for struggle of existence. It prepares a man for social service, develops his character and finally imbues him with the spirit and courage of a lion. He emphasizes on spiritual development of style along with material advancement. Education is dead process which prepares a man for struggle of existence by making himself reliant and by developing his character and intelligence. It is in fact according to him education is a lifelong process. He believed that real education is dead which enables one to stand on one's feet. According to him we have hold on the special and secular education of the nation, we must dream it, talk it, think it and must walk it out. Actually if we discuss Vivekananda's educational philosophy then we can discuss Vivekananda's educational philosophy mainly into the six dimensions, how his philosophy influence the aims of education, the curriculum, the method of teaching, the disciplines, the place of the teachers or the role of the teacher, place of the women in the Indian education system particularly. Let us discuss one by one in a very brief way because regarding aim of education Swamiji has summed up the aims of education into two words basically then man-making. According to him the ultimate aim of all education and training is man-making. Education should create self-confidence and self-realization based on the balanced human relationship. Swamiji remarks that aim of education is producing man of iron muscles and steel nerves to promote national development and produce fearless and physically well-developed citizens of tomorrow. In his words power is life and weakness is dead. Stressing the need for mental development of the child he wants the kind of education which enables the child to stand on its own feet. The ideal of all education and training should be designed in such a way that it should develop the moral character and personality development of the individual. Besides development of spirituality, serving of mankind, promotion of universal brotherhood, material, technological and scientific processes are some of the essential recommendation of the Swamiji to prepare the site for survival in this world. So regarding curriculum, in order to achieve the aims of education which was advocated by the Swamiji, curriculum included those subjects through which the material progress along with spacial development can be brought. According to him a curriculum should have basically three parts for spacial perfection. Swamiji described religion, philosophy, for material advancement and prosperity. Swamiji recommended language, geography, science, political science, economic, psychology, art, agriculture and technical subjects and for physical development he advised games, sports and other physical exercise. Along with Samoskrit and other Indian vernacular he also recommended the teaching of English language and literacy. The study of humanities with special reference to Indian culture, science, geography, social science, economic, psychology, arts, agriculture, industrial and technical physical education were also emphasized by him. In terms of method of teaching he actually prescribed the same ancient methods of instruction which were in practice in Gurukula like yoga, meditation, self-learning etc. In that system Guru and his disciples lived in close association like the members of a family. Basically he recommended the practice of yoga for controlling the mind and the emotions, deep meditation for the development of mind, Brahmasario is necessary for the power of concentration. He emphasized one self-learning where Guru will walk as guide and helpers only. Activities for developing creative potentials, lecture and discussion method for elaborating essential facts. Guidance and counseling by the teachers is essential and very helpful to remove doubts of the side. Behavioral sense through a fine model presented by teacher and individual guidance of students by the teachers. Our regarding discipline, Swamiji emphasized self-centered education in which child is given full freedom for activity and self-learning. Child should be given full opportunity to develop in a natural environment. If we look at the place of a teacher then the baby can actually emphasize the fact that education should be self-centered and he states that the true teacher is who who can immediately come down to the level of the students and transfer his soul to the students soul and see through and understand through his mind. So the main function of the teacher is to eliminate obstacles on the way of the self-development of the side and help him in making the potential as well. The main duty of a teacher is to provide a suitable environment for all ground development of the side. Again if you see the place of women in his educational thought then it seems that he was empathic that women must be educated for he believed that it is the women who mold the next generation and hence the destiny of the grantee is highly dependent on women's education. According to Vivekananda there is no sons for welfare in the world unless the condition of women is improved. So see you in the next part of this unit. Thank you.


If you're nervous, right, if you're deep down inside, you may be trying to hide it, but deep down you're nervous, they can feel it. Even if you're trying to hide it, even if you're doing a good job of hiding it, they can still tell. So you have to get to a place where you are genuinely comfortable with in these very uncomfortable situations. And so for me, for me, it comes back to the business that everybody wants to get to is the business in which you're not out looking for the clients, but the client is looking for you. But obviously that is built that doesn't, you know, miraculously appear. You have to do things consistently in order for you to achieve that. Because again, in the concept of today business and tomorrow business, in order for an agent to get to that point, it has to be a combination of consistent follow up presence in their, you know, online spaces. What else would you say, like would you narrow it down to that? Yeah. Yeah.  I mean, that's what everybody, that's everybody's dream, dream business. Right. I tell you what it is. The sales business and the personal branding business looks exactly the same for the first three to five years. You're out there on the outside. It looks the same. You're hustling, you're bustling, you're trying to talk to people, see what you can do to, to put a deal together and help people. Right. Here's the difference though. The personal brand or is accumulating clients, whether they want to do anything or not, and they have a system in place to build that brand after the fact. Whereas when you make that great first impression, there's a machine in place that allows them never to forget who you are. The sales agent doesn't do that. They're throwing away people who aren't motivated right now and they're not staying in touch with clients after the deal. That's the difference. One is accumulating humans, humans in the market, and the other one is just looking for sales today with disregard to anything for the future, disregard of anything, you know, as far as people not being motivated and who's going to win. Right. So the sales guy, maybe he does more sales in the first year or two, but I'll tell you this. The snowball is building for the personal branding agent. Right. The snowball is building and then one day you're going to wake up and you're going to be Ricky Caruth. You're going to be doing a hundred deals a year without making a single phone call, no social media, no nothing except for a weekly email. That's the machine that I've built my personal brand on for real estate. So to answer your question, you know, you mentioned follow up guys, listen, the fortunes in the follow up, right? Maybe. Okay. Maybe. Here's the thing. What I've learned about follow up here in the more recent years, people are putting way too much weight on follow up. They're putting way too much time on follow up. Okay. Here's why. What I've realized is that people that are going to do deals. Sure. You can follow up and get some deals that you wouldn't have when you followed up. True. But just think about this for just a second and try to understand, well, maybe I need to follow up, but maybe I'm spending a little too much time there or too much effort or too much, I'm spending too much energy thinking about follow up because here's what I've learned. People that are going to do deals or do business with you, they're going to do business with you regardless if you follow up or not, right? Most of them. Most of them. Not all of them. Most of them. And then the ones who aren't going to do business with you, they don't, there's no need in following up with them, right? I really think follow up is mandatory. We all need to do it, but I think the world we're living in is putting us in a position where we're putting way too much weight on it and not enough weight on, we got to go find more clients. Think about if you eliminated some of this follow up that you're doing with people, right? Really think about their situations because I'm a big, I'm a huge component of finding out why people want to do stuff. I got to hear the backstory. I don't care what's going on, where I got the lead, what they're doing. I need to know why, right? When I can get deeper into why they're doing what they're trying to do, that's when magic happens, guys. If you can start focusing every client conversation around why they're doing what they're trying to do, I think you're going to find far, far, far, far more success with developing the relationship, getting the deal done, helping them, feeling more gratified at the end. You feel closer to your clients too, and you're almost emotionally invested at that point, and they love you for that because you're a good person, and they see that. Finding out why people want to do stuff, I think, is one of the biggest keys to the whole puzzle of sales. I think a lot of people are skipping. I'll say something about that, Ricky, based on also something you said, which is that success depends on one thing, which is making people feel comfortable with you.  It just makes them feel more comfortable with you. But let me ask you this. How does the agent feel comfortable with the client? So we're trying to get the client feel comfortable with us, but how does the agent feel comfortable with the client? Well, and that's the key to making them feel comfortable with you, right, is being comfortable with them, right? People feed off other people's energy, okay? That's the key to this whole thing. People feed off other people's energy. So if you're nervous, right? If you're deep down inside, you may be trying to hide it, but deep down you're nervous, they can feel it. You can't hide it.   Your eyes, your breath, everything. Even if you're trying to hide it, even if you're doing a good job of hiding it, they can still tell, right? And so you have to get to a place where you are genuinely comfortable with in these very uncomfortable situations. And so for me, it comes back to intentions, right? When you fall back on your intentions that you really are there to help people, there's no ulterior motive, there's no expectations, there's, you're not in it for you, you're really in it for them, and you fall all the way back on that 100%, then you can be confident, because at that point you don't care what other people think.  I don't wanna sell my house, good. That's not why I'm calling you, you know? I'm calling to see what I can do to help you, ma'am, you know? When you go all the way to the point where you are generally trying to use your business to just help people. Guys, listen, when you use your business as a vehicle, okay, to help people, think of your business as a service, which it is, it's a service. We're too far into the gotta get appointments, gotta get listings, gotta make sales, gotta do this, gotta do that mentality, and we're not thinking about our business in terms of it actually being a service to help people. Like think of your business as like, almost like you're a volunteer for a community service job. Think of it like that. You are the highest paid volunteer workers in the world, okay, that's what you need to think of yourself as. You need to go into every situation expecting zero, literally open your ears and listen to why they're doing what they're trying to do, and then help them do it. Listen, closings are happening every day by the truck loads. Why aren't you guys closing those deals, right? You're not talking to enough people listening to why they're trying to do what they're trying to do. The closings that are happening every day are happening with real estate agents. Sure, there's a little percentage over here that are for sub-owners and off-market deals and all this and that, but look in your MLS and look at the truck loads of deals of people they want to use an agent. They have to use an agent. They don't know how to do the deal. It's too complicated. There's too many variables. There's too treacherous. There's, you know, the market is a wild place. I mean, I couldn't come to you guys's market as great as I am here locally. I couldn't come to you guys's market at all. It would be like looking, it would be like trying to read Chinese, trying to figure out what something's worth or reading the contract. I know I've been doing this 20 years and I couldn't come to your market and I wouldn't feel comfortable unless I was using one of you guys as a real estate agent. That's how bad it is. You can imagine how bad it is for an actual just every ordinary day consumer. You know, it's tough. They need us, okay? So you got to start thinking about the fact that people need agents and that you're offering a service and you need to walk in every situation with no expectations. Listen, I'm here. This is me. This is what I do and I'm here to help you. You know, what can I do to help you, right? And if not now, is there an agent you would work with? You know, I'd love to stay in touch with you. What's your email? It's like you're pleading. You're pouring your heart out, you know, because you genuinely care and that's when you can start to feel comfortable.


All right, guys. Just want to talk a little bit about how to have some fun with your own little pen test Army. So as you can see, by the way, at this title, I social engineered myself. So I'm very proud of that. I social engineered myself, the title of hacker and residence at university redacted. All right, so what does this talk about anyway? I'm going to talk a little bit about doing hacking in forensics with some small low-power devices. It turns out that the devices I'm using are arm-based devices in the Beagle board family. And what I've done is pretty much made my own custom Linux distro, which I call the deck.  You know, the stuff that people haven't used in years. I didn't port that stuff. I ported everything else. I'll talk very briefly about porting stuff to a new platform. I don't want to focus on that too much. A lot of the stuff I want to talk about today, it's in the slides mostly just so that it's in the slides. It's on your DVD. You can look it up later. Ask me questions, whatever. I also want to talk about how you can perform some coordinated attacks with your little army of pen-testing minions. So who am I anyway? I'm a prof at university redacted. And hacker and residence somewhere in the Midwest. I've been programming since I was 8 years old. Been hacking hardware since I was 12. Also been known to fly some planes, build some planes and just have a lot of fun. What I'm going to talk about is, you know, choosing a platform that was appropriate, selecting kind of a starting point, a base OS. Building a base system. And then the easy part, getting some tools out of repositories and such. And also talk about the harder part where you can't get things out of a repository. How do you go about building stuff? For a little arm-based device. Then I'll move into networking with 802.15.4 or XP networks. And talk to you guys a little bit about that. Talk about how you can build your own stuff. And I'll have some demonstrations. I apologize via screenshot. As we all know, live demos are never a good idea, especially in a crowded size. But I will be available later if you guys want to, you know, get touchy-feely with some of this stuff and play with it. Talk about attack networks and some future directions. Okay. So picking a platform. This is my criteria. I wanted something that was small. Something that was low power. Something I could afford. You know, I don't make much at University of Redacted. Something that was mature. Had good networking support, good community support, had some nice input and output options. And the winning platform, I kind of gave this away, is the Beagle board family of devices. In particular, I started out doing this with the Beagle board XM, which is a desktop replacement device. And, you know, have moved to having something that runs as well on the Beagle bone and the new Beagle bone black. That will talk a little bit more about in a bit. Pretty cheap stuff. Beagle board XM, $149. And the Beagle bone black list for $45. And you can actually buy it for less than the list price, unlike some other devices out there. Half a gig of RAM, networking, USB, DVI-D, output, all that good stuff. So here's a little picture of the Beagle board XM. This is stolen off the Beagle board website. It gives you some of the specs. You can see it's three and a quarter inches square. It's pretty small. And here's the other device that you would be more likely to use if you were starting today. This is the Beagle bone black, also known as the Raspberry Pi Killer. This came out in late April. It lists for $45. I've spent an average of $42 on the ones that I've purchased.  I know at least somebody is going to say, why didn't you use the Pi? Well, here's why I didn't use the Pi. The Pi is not near as powerful. It doesn't run Ubuntu. It's got some ancient ARM architecture that nobody supports, including Canonical. It's not as mature in terms of the platform. The Beagle bone, the original one, has been out longer than the Pi. And there's no real cost savings, if any. Usually, I think if you try to implement this stuff with the Pi, you would probably spend more money, not less money. Even now, it's not easy to go buy 50 PIs in this country, at least. And a lot of people have had some problems with some flaky boards. Also, even though they're not as powerful as the Beagle bone black, they consume about 50% more power. So, you know, I've talked to a lot of people about their experience with the Pi and I hear a couple of stories a lot. I never got it to work because I had to go download, you know, Raspbian and, you know, that stuff just never worked. So that's one story I hear a lot. And I also hear that it worked really great for about two weeks and then the flaky power circuits failed. And then the other, I think maybe slightly more common story I hear is, yeah, I want to do something really cool. And then it wasn't powerful enough. But it can flash LEDs. It's really cool. It's like, blink those LEDs. All right. Well, I think I'm doing something a little bit more than blinking LEDs. You can judge for yourselves here coming up. All right. So now that I've selected a device, it's time to select a base OS to start with. Well, again, unlike the Pi, if you buy a Beagle board, Beagle bone, it actually comes with an OS and you can plug it in and it runs. They even give you a power cable for the bone. It's amazing. You don't have to buy extra stuff. So it comes with this thing called angstrom Linux that most people have never heard of unless you like to do embedded Linux stuff. It's not a bad distro. It's optimized for the hardware. But for our purposes, it's not the best. You know, the guys that made this initially weren't all pen testers.  Because up until recently, nobody was doing that. So I chose Ubuntu. Ubuntu is available as you all probably know. Backtrack was based on Ubuntu. A lot of support in the community for Ubuntu. Good repositories and all that. All right. So now that I have an OS that I've picked, it's time to go about installing it. So on the Beagles, on the Beagle bone block in particular, it has two gig of internal storage, which isn't quite enough for me. The image for the deck is over six gigabytes. So I have just a few tools in there. You know, I forgot though. I should have put a little program in there to blink LEDs, but I didn't do it. I apologize. You're welcome to submit that to me. Maybe I'll add it. So what you want to do is you get a microSD card and you create an image. And if you're going with Ubuntu, you can go to canonical. You can get their images. Or there's a guy named Robert C. Nelson. I think this guy just writes stuff for embedded devices all day. I chose to use his branch of Ubuntu because it's nicely optimized. It's updated a lot. You can find some good instructions on how to do this stuff at the link provided if you want to do so. All right. So now I've got a device. Got a starting point. I've ported some of the tools or I'm getting ready to port some of the tools. So what's the easiest thing? Well, I want this tool. App, get, install, and pray. All right? And a lot of times you get lucky. Sometimes you don't get quite that lucky, but it's great. A lot of people like Ubuntu. And so a lot of times if you can't get that to work, you can at least get a dev file. And you can use d-package to install it. And when in case of a dev file, what I found is if you're running something that's based on an interpreted language like Perl, Python, Ruby, et cetera, it tends to work pretty well. Kind of out of the box. And if it's a C-based program, if you have the appropriate libraries, you're probably okay as well. All right? Now, sometimes you actually have to build stuff. Now, in my experience, this was roughly 10% of the time. So 90% of the time I either did an app get installed and it worked, or I got some dev files and maybe played around a little bit and it worked. All right? So a couple of times you actually have to build this stuff. All right? So if you've got to build this stuff, you have to make a decision. You have to say, do I want to build it on my Beagle or do I want to build it on my hex core desktop with gobs and gobs around? All right? If you build it on the Beagle, it has the advantage of being pretty straightforward, has a disadvantage of possibly being a little bit slow if it's a big program. All right? So of course you can cross compile. It's a little bit more complicated. But you can take advantage of your heavier computing power. All right? So if you're going to go with the native compile, it's pretty basic. Do a pseudo app get install build essential, singular, not plural. I don't know why, but that's the way it is. And you're pretty much on your way. You download your code, do the standard stuff and you build it. All right? Something to keep in mind if you happen to be using the Beagle board, XM, be aware that if you're SSH-ing in there and you're using DHCP, every time you reboot the machine, it gives you a new MAC address, so you tend to get a new IP address. So if you're wondering, hey, why did that move yesterday? Well, just don't ever turn it off. You'll be fine. All right? I'm not going to cover this in detail. Just want to include this in the slides. But cross compiling, the most simple way to cross compile is something. You download a tool chain and you kind of do the standard thing.  The only difference is if you look at the configure line, you'll see that it says configure and then there's a dash dash host equals arm blah blah blah blah. All that is telling the compiler is hey, guess what? I'm not building for whatever I'm running on it, whatever machine I'm running on, and that architecture I want to compile for the other architecture. And other than that, it's pretty much the same as building source code for your own machine. You can be a little bit more fancy and you can start using Eclipse. And there's some good instructions on how to do that online. And you can get really, really fancy and enable remote debugging. All right? And I refer you to Jan Axelsen's tutorial which has a link to that at the bottom of the page. All right? If you have questions about this stuff, ask me later. All right? Okay. So now we have a device. We select a device. We got an OS. We ported all of our tools over. Now let's talk about networking. All right? How many of you are familiar with 802.15.4 networking? All right? Like maybe 10 of you. It's not a lot. All right? Also sometimes called XB networking. Sometimes you might hear about ZigBee networking which technically is built on top of XB. But just going to give you a nice brief overview of what it is. Talk about some of the hardware. Some simple cases where you just have two XB radios. And then some slightly harder cases working up to the really hard stuff where you're actually doing true mesh networking. All right? So typically you'll find these XB adapters in industrial settings when people are doing stuff with low power embedded devices, they like to use XBs. And the XBs have many different forms. And they usually come in two flavors. They have the basic ones or the regular ones that have a range, you know, of one to 300 feet depending on the situation. And then we have the pro adapters which have a range of up to a mile. All right? They have two different modes of operation. They have what we call AT mode which for some of the older among us, you might recognize AT commands. It's from these things called modems, you know. But some of you are like, I heard about those once. It's fairly low speed about 250K. And it supports a lot of different topologies such as peer to peer networks, star networks, and mesh networks. And these are made by a company called Digi. They're up in Minnesota.  They're interchangeable and interoperable. All right? So I can have a network where part of my network is running the regular adapters and part of them are running the pro adapters. And that works. All right? They interoperate just fine. One thing that's kind of a pain in the butt, working with these devices, they use a two millimeter spacing, not the standard 2.54 millimeter or 10th of an inch spacing. So you probably have to get some sort of an adapter. A lot of different antenna options. When you're buying these things, be careful to buy compatible adapters. You'll see series one adapters. And series two adapters sometimes refer to ZB adapters. All right? You can interoperate regular and pro, but you cannot interoperate series one and series two together. All right? They're not compatible. So buy all of the same kind. All right? So if you get these little XB modules and you want to configure them, pretty much what you can do is if you have a USB adapter, it's usually the most easy way of doing this. You can put this in its adapter, plug it in to your computer, and they provide some software you can run. And you set up different things. So you configure each of these modems. You give it a baud rate. Tell it what kind of device it should be if it's a series two device. You set the channel. And you also set something called a pan ID. All right? You can choose something great like maybe, I don't know, 1337. Probably wouldn't go with the defaults, but you can change it. And you pick a destination low address and high address. And it's pretty simple. I'll talk about the different modes that it will operate in.  And go forth and do some XB networking. So what's the simplest thing to do? You have one drone and you just want to remote control it.  My lunch box of course has a little computer in it running the deck. And why is it buzz light here? I'm going to hack you to infinity and beyond with it, buddy. All right. So you by default, these XB adapters are meant to run in what's called transparent mode. And basically what it does is if you set up the addresses properly so that two of these are pointing at each other, it makes a wireless serial port. So stuff just goes back and forth using the normal serial port protocols. And you can do this and then set up your drone to use TTY, which again, some of you will be like, what's that? Something that people use in the old days to tell net into stuff. So it's pretty simple. There's a lot of information on how you set that stuff up and you can do it. That's one way you can go. Now, you can go and do the same sort of thing and have multiple drones. And all you need to do is make sure that each of those drones is having a destination address of your command center.  You know, for them, they think that it's exclusive. You know, it's like they're all Tiger Woods girlfriends or something. I don't know. They all think that it's just them. They don't know about the rest. And it's pretty simple. You don't have to do any programming. And you can just use the AT commands. So how does that work? You open up your favorite terminal program. If you want to change something, all you have to do is hit plus three times, wait a little bit, and it'll say okay, and then you can give it a command, such as this command that says, hey, change the destination low address so that I can talk to this drone now. And then I can go and write those things to my modem and off I go. I can also use an API mode, which is what I would personally recommend. All right. The nice thing about API mode is that things are set in packets and it's a lot better performance and error correction and all that good stuff. All right. By the way, a little tip.  Why isn't it doing anything? And you're thinking, it's my Python scripting. It's probably just that you misconfigured the modem. So there are different ways you can talk to these modems. You can use Java. There's a Java protocol and a library for that. There's a Python library which I used. Or if you want to kick it old school, just send those raw commands yourself. You can do that. And I recommend that you use API mode if you've got more than just one drone. So you can also go to multiple drones. Again, this is technically not really mesh networking at this point. It's really point-to-multipoint. And you set up this peer-to-peer connection and you get better performance and all that. So it's a good thing. Now, one possibility you can do is what I did. You can write some simple Python scripts so you can create a command center and then have all of your drones sit there and just wait. Wait for commands on the XB. You know, wait for commands to come over the XB. It's not a line, I guess, or wire, but virtual wire. One downside of going this way versus the TTY route is you can't run an interactive program, at least not yet, the way that I've done my scripting. But it does work pretty well. So you can send commands. You can get responses. There's also a facility in there to get announcements. So I might say, hey, you drone over here. Please crack this Wi-Fi network. And then when it's done, it sends me a big announcement.  The password was password one. So all the code for all the stuff I'm talking about today is available out on my website. But, you know, I'll give you some of the highlights. All right. Now, if you really need to do the true mesh networking, you can do it. One thing that's cool about this method is that you don't have to change anything. There's no changes in your scripts. It all just works. And you can take out your series one modules, put in series two modules. And really, it's a matter of just configuring them correctly before you plug them into your drones. Something to keep in mind, though, if, for example, you set up a device as a router, routers are not allowed to go to sleep because routers that don't respond are bad. End devices are allowed to sleep and you can save them battery power. All right. So what's the simplest case? You know, again, let's back up a little bit. You know, we selected a device, got our OS, got all of our tools and figured out how to do the networking thing. Well, the simplest case, you just have one drone. You set it up and you can have from a distance. You know, what's the advantage of this? It's running 24-7. You're not suspiciously sitting in the parking lot with a big antenna in your van. That's like, what have they been doing? You know, oh, that's the famous FBI van number six, right? A little story on that last weekend, I was at Maker Faire up in Detroit and I was running some of this stuff and someone came up to my booth and he goes, oh, look, there's FBI van number six right here. I wonder why that is. I'm like, dude, I know it's you. Oh, what do you mean? I'm like, dude, you're six inches from my receiver and you're the strongest signal. So I'm pretty sure you're FBI van number six. Anyway, so, you know, you can lounge by the pool at the hotel down the street. You know, especially if you go to someplace like Vegas, it's kind of hot here, right? You want to sit by the pool or whatever and you can hack away. Other things you can do, you could have multiple drones and you can interact with each of the drones and use your imagination, right?  Of course you can't, right? However, you know, the nice thing about these guys, they're cheap and every one of them has a full copy of the deck. So they each have six gig worth of security tools, all right? So you don't have to go, oh, I wish I had this. You know, it's on there, right? It's pretty much all there.  All right. So let's talk a little bit about building some hardware. So you want to build some accessories. This picture here is of a very simple power supply, right?  You can see the scale. It's pretty small. It's next to an SD card. So you want to power your drones. I'm not doing anything real fancy here. I'm using a 7805 linear power regulator and a couple of capacitors in order to smooth stuff up. And a battery or two. All right? A word on batteries. Now, I just showed you a picture with a 9-volt battery clip. And that works great and 9 volts are nice because they're compact, but it's not real efficient. All right? For one thing, I'm dropping from 9 volts to 5. So I'm wasting a lot of energy. And that all goes to heat. And also, 9-volt batteries don't have a very good energy density when you compare them to things like D cells and stuff like that. So something to keep in mind. Other things to keep in mind when it comes to power, you can have a bigelboard or bigelbone black running full blast, all right? Running 100% CPU. And it uses about a watt. It's like 1.1 watts or so of power. It's not a lot. How much do you think the Raspberry Pi does? It's over 2. And it does less. But it doesn't matter because all you can do is blink LEDs and they're pretty efficient. So that's all good. But one thing to keep in mind when you're using your mesh networks, they do use power, the transmitters. So don't just sit there and transmit constantly. Make use of things like sleep modes and such. All right? So some power options. Here we've got a couple options. USB cable, different power adapters. And then on the right-hand side you can see some of the battery based adapters. So we've got one with 2, 9-volt clips so you can hot swap them if they start to fail on you. And then another one with some AA batteries. All right? 802.15.4 hardware looks kind of like this. Here I've just made some simple adapters for my XB modules. It's four wires that you have to solder. Here's the same thing in a little case. By the way, some people asked me about this one. It doesn't look like an XB. In order to get it in my little case, I had to put the XB upside down. That's why you don't see an antenna or anything. Okay, so you probably need an adapter for your XB. And again, you can get two kinds of adapters. You can get a UART or serial adapter, which is pretty basic. You can have four wires to connect. All right? You can also get a USB adapter. You're probably going to want at least one of these in order to hook it up to your PC and to program it. And you don't have to solder or anything. So if you're connecting it to your Beagles, if you bought the USB adapter, there's nothing to do. Just plug it in. If you have the UART adapter, you have to solder the four wires. You can find more details about that if you look into my slides. And then you have to tell the Beagle, hey, this is what I'm using these pins for. All right? A little note on that. The older Beagle Bone, the Beagle Bone White used the older Colonel version. And there was a way of doing this stuff. You just have a couple echo commands that are shown here. The new Beagle Bone Black uses a 3.8 Colonel. And they dramatically changed how that stuff works. So I don't have time to go into the details on that. But, you know, have a look at my blog and I'm hoping when I get home to have a nice detailed article on that. Other hardware, capes, or if you're familiar with Arduino shields or capes in the Beagle Bone world, something that I'm working at right now, I've actually been approached by some folks because some people don't like to solder, which is cool. I like to solder, but we're working on developing a cape that will have an XB socket, a network switch so you can inline it, and a USB hub in case you need some more USB, and possibly regular Wi-Fi, 802 11 Wi-Fi, and maybe an optional battery pack. So that's something that might be coming out. Other things in terms of hardware, you have to have a cool container for your stuff. You see I have my G.I. Joe black packets, my Buzz Light your lunch box. If you look in the lunch box, it looks kind of like this. You know, I've got a touch screen, I've got my Beagle on the back of it, USB hub, network hub, keyboard, mouse, all that good stuff. All right.  Which happens a lot, right?  Pretty cool. There we go. Other things you can do, this is just showing you the same hardware in another format. Okay. So the rest of the time, I want to just real quick show you what kinds of things can you do with this platform, starting with what can you do, just one of these devices, and then what could you do if you take a couple devices, put it together. All right. So, you know, here's the first demo. Some of you might recognize the motivational music as last year's Defcon CD. Run it on my lunch box, you know, run an end map on my network, and sure enough, I see, I don't know how visible, it's kind of visible. I tried to highlight some stuff, and it's like, oh, there's something running on port 445, which tells me that it's probably what kind of a box. Windows. Our favorite target. So, port 445 means let's try our favorite exploit, and what's our favorite exploit in the whole world? 0867, right? It's at every con. So, sure enough, here I am, running Metasploit, and successfully getting a shelf on a Windows XP box.  I'm running Metasploit. Okay. But your LEDs are cool. I'm not dishing your LEDs, okay? All right. So that's something you can do. What other kind of things can you do? How about crack a little Wi-Fi? Run up Aircrack, you know, start up Airmon, do a little scanning, see what's out there, find someone to attack. Yeah, this guy's got a great password. Password 1, it is. All right, so, you know, crack a couple network passwords. Of course, we like to crack passwords in general. Run up Hydra. This is Hydra running against a router. And you can see that this guy's not even that good. He went with straight up password. Couldn't do the one. All right, well, maybe people have stuff a little better, right? But how many of you like to use WPS cracking? What's your favorite tool for that? Reaver, all right? By the way, hit little tip. Some of those cheap routers, when you untick the box for WPS, it's still on. So you might want to haul out Reaver and check and make sure it's actually turned off. All right, so here's just a little run with Reaver. And after a bit of time, sure enough, boom, I got the password, which was, password one again. I call this Pony Windows 7 like it's a Mac, right? And some of you might say it should be Pony Windows 7 like a boss. Yeah, kind of, but about a year and a couple months ago, there was this big vulnerability that came out. I remember some of you were like 400,000 Macs, or maybe it was more than that. Infected. And all the PCs went, uh-huh. You know, all of us did. But so, you know, the Macs had a problem, right? With Java.  And it's like, well, you did. Well, then you got all the victorious Windows people, right? They're like, well, see, I told you. Guess what? They had the same vulnerability. So again, I just load up Metasploit. Again, this is all running on a little Beagle, right? I might even flash some LEDs on the side. Okay? So, sure enough, bam.  I've got a, I've got a shell at a little Windows 7 box from the University of Redacted. Don't pretend you can't read what it says there.  Some of you are probably familiar with the term script kitty. Aaron Phenix Phinnan and myself, we came up with a new term, a click kitty. A click kitty is someone that's not even a script kitty. So they can only use GUIs. They can only use things like Armitage and Fern Wi-Fi Cracker, which came out last year, right? It's a nice little tool if you're not familiar with it. It's basically point-and-click ponies for Wi-Fi. You pull it up and it says, oh, I see these adapters, these networks. Which one shall I attack? And then it tells you when it's done. So it's pretty basic. It's kind of neat. All right, enough of that. Let's talk a little bit about bringing in multiple drones. So again, if you take the trivial case where you're using TTY mode and a couple of drones, you can go in to your terminal program. You can connect to one. If you want to switch, again, you just do the plus, plus, plus. Give it some commands and then start switching to the other. It's sort of legible, I guess. But I'm actually running two drones here in this example and I'm sending commands to both. So if you want to use the Python scripting, I've done something extremely fancy, all right? I have a little command console in one window and you can send it commands and you can switch which drone you're sending commands to and get announcements in that window as well. And then I have all of the responses I captured to a file and I use this extremely sophisticated tool to display that file. It's called tail dash f. So basically here you can see this is my command console. I just have a really simple API, right? It'll say, hey, what command do you want to send to this drone? And if you say colon and a number and nothing else on a line, it switches to another drone. So here's just some basic output and they'll tell you, hey, this is what I've sent to this drone and this is what I got back. Pretty basic stuff, all right? This is just giving me an idea. There's nothing like really awesome in the scripts that I wrote here or anything like that. Okay. So some future directions. I'm going to continue to try to add some useful stuff. You know, I started on this work about a year and a half ago after DEF CON last year. I actually added some packages. The very first version of the deck came out in September of last year. So between DEF CON and that time I actually did some of that stuff. And optimizing some packages. Looking at some other output options. Possibly exploiting some USB on the go functionality. Some of you may have done some work with the teensie. Any of you use the teensie? No? A couple of you. Done a little bit of HID hacking. You know, you set up your little keyboard and enter some commands. Well, that's with a 20 megahertz 8-bit processor. I got a gigahertz 32-bit ARM processor. I can really push some commands out to you and, you know, do some serious logic. The other thing I'm working at right now, it's my next big thing, is literally making this platform fly. Hoping to have that stun for GERCON in September. But basically I am going to install this platform inside of an aerial drone that's capable of vertical takeoffs and landings. So you can fly by a target, do initial recon with it, take this sucker, land it on the roof, hack them, and then fly away. And there are different scenarios there, too. You could potentially use a, you could set up your XB in the drone as a router and then maybe pepper the lower powered drones around the building, in the building, wherever you can. So that's something I'm working on. The other thing is, you know, maybe you don't want to hack from down the street. So why don't you hack from across the world? There's this beautiful thing called an XB gateway device. I have a couple of these at my office. And so what you do is you make sure the gateway is in the range of your drones, and then you can take your gateway possibly hook up to someone's free internet at their cafe, plug it in somewhere, and you could be over in Australia doing this pen test. It doesn't matter. And as I said before, I'm working on developing some pen test capes. And also right now I'm currently working on it. I didn't quite have it finished probably in the next couple of weeks. If you look at my website again, it'll probably be up there. I want to be able to send simple files across the XB. So for example, if I want to send a new script to be run, I just want to be able to send that over the XB and not have to bother with things like SSH and all that good stuff. So all right. Here's some references that you can look at. And if there's any questions, there was going to be the Q&A lounge which went away. So I'm going to recommend that if you have any questions, come see me at the Chill Out Lounge later. I'll bring my little toys and you can have a look. And I think we're just about out of time. Do you have like three minutes? One question? One question? Okay. Does anyone have, I think we have time for maybe one question. If not, I'll head that way. I do not currently secure them. I could. There is support in the 802.15.4 spec for encryption. I'm just not bothering to use it. Because honestly, one of the advantages of 802.15.4 is essentially out of band for most people.  But if you use an 802.15.4, it's on different channels. People have no idea that's going on. But yeah, you could easily do that. I just don't because I'm lazy and it takes a little performance hit.


Hello and welcome to the session. I am Asha and I am going to help you solve the following question which says the angles of a quadrilateral are in the ratio 3 is to 5 is to 9 is to 13 find all the angles of the quadrilateral. So let us begin with the solution and let A B C D B the required quadrilateral then we are given that the angles of the quadrilateral are in the ratio 3 is to 5 is to 9 is to 13. This implies angle A is equal to 3x, angle B is equal to 5x, angle C is equal to 9x and angle D is equal to 13x. So in the figure angle A is 3x, angle B is 5x, angle C is 9x and angle D is 13x where x is a positive real number and x is greater than 0. Now as we know sum of 4 angles of a quadrilateral is equal to 360. So this implies angle A plus angle B plus angle C plus angle D is equal to 360 degree that is 3x plus 5x plus 9x plus 13x is equal to 360. This further implies that 30x is equal to 360 or x is equal to 360 upon 30. So in cancelling we have 312s are 36. So we have 12 degrees that x is equal to 12 degrees. So this implies angle A is equal to 3x which is equal to 3 into 12. So angle A is 36 degree, angle B is 5x. So 5 into 12 is 60. So angle B is 60 degree, angle C is 9x. So we have 9 into 12 which is equal to 108 degrees and lastly angle D which is equal to 13x. So we have 13 into 12 which is equal to 156 degree. Therefore 36 degree, 60 degree, 108 degree and 156 degree are the angles of the quadrilateral. So this completes the session. Take care and have a good day.

Hello everyone and welcome to a very special video today because we are looking at what seems to be or most likely one of the best fan games that the Jurassic franchise has ever seen. Now on this channel we've covered a lot of fan-made Jurassic games, recreating maybe just even just specific scenes from individual movies. For instance Jurassic Dream was a way to drive around Jurassic Park and just sort of enjoy the way Jurassic Park looked before it went into chaos. There was Jurassic Park S which was like seeming to be a Jurassic Park fan game and then it turned into like a Silent Hill horror game which was loads of fun to check out. There was also the T-Rex breakout which was just taking that one iconic scene from Jurassic Park where the T-Rex breaks out and just you know having fun with it. There was another one I think created by the same guy which was the Raptors in the Kitchen and that's all it was. It was just that one scene from Jurassic Park where the Raptors go in the kitchen and you try and survive and if it's taught me anything it's that the fans really want just a recreation of Jurassic Park or maybe a story told in Jurassic Park where you can free roam third person first person whatever but for some reason in the god knows how many years 30 years that Jurassic Park has been out we have yet to receive a game even close to it or at least an official game but this one created by Cronordigan seems to be delivering on all of it and what's even more amazing about it is that this isn't made in Unreal Engine or something that a lot of the other games have been made in. This is made in PlayStation's own Dreams which is basically a way to make your own game but I assume it has its limitations however we're about to see that those limitations don't seem to have phased this person one iota so without further ado let's have a look at the trailer for this upcoming Jurassic Park game and fingers crossed that it doesn't get slapped with any cease and desist from Universal because literally this is what we want I'm excited let's go creation is an act of sheer heck yeah it is heck yeah it is this place I wanted to show them something that wasn't an illusion the flea circus John Hammond that's what you need something that was real beautiful something that I could see the ivory interesting of course the visitor center go I can't think through this one John you have to feel it I've done an amazing the river adventure I was overwhelmed by the power of this place but I made a mistake too I didn't have enough respect for that power and it's out now the only thing that matters now are the people we love I look so cool Alan and Lex and Tim look at that that looks amazing and actual explorers because you don't have to get the license oh that's cool I love that you've got the um the motion sensors as well that were in the novel they were in the super nintendo game I think as well I mean it's it's delivering a lot including the river adventure which is amazing this is some first person oh that looks great oh oh oh that's cool that's a river adventure but like different Jurassic Park operations made in dreams beautiful oh that's all we want that's all we want is like fans of the franchise is just to be able to walk around and enjoy what you know John's Hammond creation could have been you've got the river adventure which is technically now an extinct ride except for it well it is in California I think it still exists in Florida maybe or maybe actually Florida's the only places being destroyed it still exists in japan and california and really some of the universal parks but it looks like they've just recreated scenes like the brachisaurus here you've got maybe some displays of the different fauna that are in Jurassic Park Avery this is probably the only bit where it looks a bit unfinished like behind this looks like an image it doesn't look like it's you know but again this isn't really so tall and it's just amazing to me that this is created in like a third party software in in order to even make this it's crazy and then the classic river adventure text there they do show these this bit which is or like throughout the ride where you've got the brachisaurus you've got that lofasaurus spitting on you and the t-rex but it seems like there's a little bit of a twist on it now i'm kind of curious as to how much of this is scripted events i don't know what's going on with the texture of this guy's arm ooh think he needs to see a dermatologist or something uh you've got the sea yeah you've got the light from when at least that leg goes in to turn on the power there the fall explorer is looking like for the explorers which is interesting this is interesting as well i don't know if those were ever lit up in the movie because they were just the cameras to follow the track i mean it would make sense for them to have lights i suppose i think canonically they don't have lights and if you just look at it looks so good like the reason why we don't have explorers or jeeps in evolution and stuff like that is because they have to get the license from jeep or explorer to use it so that every time you see them they're like slightly off like they have the logos and everything the colors but they're they're just something like an uncanny valley above that's like so close this is an interesting bit you've got two jeeps you got the t-rex and the motion sensor uh there which is just like a lovely little touch of detail there um which the movie never really explored upon which is how the dinosaurs were kept track on that's the classic scene uh this is an interesting one i'm kind of curious as to i mean i haven't got in touch with the guy or anything but i have seen the this video floating about um but i don't know whether we're we're gonna follow a story um and as we progress we sort of follow the events of Jurassic Park um because like there's the Dilophisol scene that would spray water on you you got raptors and what seems to me maybe you got time here which says 12 38 and possibly a health maybe that could be a health indicator um and the raptor jumping attack and this is the bit where in the river adventure you would fall down uh jump down the giant water slide and the t-rex looks like it's going to be this looks absolutely terrifying i love it i do hope that you know this is ai but i get the feeling because to have ai that's this complicated look at the teeth man looks terrifying so many millions of teeth so ready to raise the yeah it looks like you know to have ai to know to crawl and stuff like that that seems a bit complicated i could be wrong though so maybe this is scripted events here i'm not exactly too sure what you got going on you've got like maybe this is when you get to the island you know you you relax and you you're about to sit down to a meal and then all of a sudden like you see a raptor shadow in the distance and like the tv goes off and stuff and that would be a great way you know maybe we could be on the island at the time of the events of Jurassic Park so when things go wrong and we are on the visitor center or in some sort of a resort because there was supposed to be those in the island too and then you you know you sort of take part in the rest of the stuff that happens here you try startups but i don't know what this dinosaur is i mean it looks like a raptor right but it could be herurosaurus because its patterns are a bit different to the the raptor and it wouldn't make sense as to why one raptor would be different because i mean as you can see this is the raptor i'm not exactly sure you've got water here so this is the river adventure and i'm assuming raptor jumps onto your boat there which is interesting you've got this reversing shot of the uh of the river adventure oh sorry a jeep running away from the tears and then this one again which is i assume when ellie's running away from the raptor after turning on the power but that looks weird if this is unscripted you know and it's just the way it's going that looks so cool and then this is another one um this was i think if you've ever been on the actual ride it's off you there's like a little command station it's like overrun or like destroyed or something when you're going up towards the t-rex but this is going backwards so you're being chased by the trick so maybe there's a little bit of a change on the actual ride itself i mean that ah look at that shot that looks so good oh yes that's the that's the money shot that's the there we go that's a thumbnail bing bing bing but it just looks so amazing i i'm i i'm astounded really by the level of detail and just the the amount of things that they've managed to pack into this i would love to see a finished version of any of these Jurassic Park games i mean you can find them all on my channel i'll probably put links in the description down below if you want to check out all the other different projects there was even some on site b to do a Jurassic Park 3 and avoiding the feathered raptors and stuff like that but every now and again you get these little gems of Jurassic media coming from the fans not from any official um you know source not that they couldn't do it because they have the money they you know really i do not understand why we don't have anything like this maybe there is maybe they're keeping stung on something maybe you know we haven't heard about it just yet but it really feels like a missed opportunity especially when we can get some absolutely astonishing fan games looking like this that are completely independent and you know i'm assuming funded by themselves there's no kick starters or anything and this doesn't show any signs of going to kickstarter um and the fact that it's on dreams you know it's it's it's playable by the looks of it it's obviously not finished but if i was to hazard a guess as to how this goes i mean you you you come to the island before allen groten everyone goes on you go on the rubber venture everything seems fine and then you know you experience the park the way it should be and maybe there's a point where everything changes when you do sit down to have your meal and then you hear raptors and then everything else happens and maybe you you know we take part in other things that are going on and maybe we switch between the two either way i would literally and not just me i feel like everybody who's a fan of the franchise would be happy with something like this um you know just to walk around enjoy it you know be chased by the dinosaurs just explore these classic locations honestly they don't even have to do much really the only problem has nightmare fuel i love this shot though the only problem with this is that it is on dreams so you do need a playstation four or five i think it is maybe even three i'm not sure but probably four or five in order to play this which is the only downside because it does mean it limits the amount of people that can play it uh however whenever it does eventually come out i'm looking forward to it will of course one million percent played on the channel i cannot wait but until then maybe if you enjoyed this video leave a like share this and also i put link to the the um the youtube of um cronautica as well in the video for this to show them the support let let them know i i sent you of course he gave me something but yes any i there's any way i can support them you know by you're making videos like this and pulling the word out that i'm happy to do it but anyway guys if you enjoyed the video leave a like and until next time i'll see you cuties later oh bye bye
