Hello everyone, I am Kirti and today I will be talking about FEDS framework, a Comprehensive Fault Attack Exploitability Detection for Software Implementation of Block Cipher. This is a joint work with Indrani Roy, Chastra Rabeiro, Aditya Hasra and Swaroop Bunya. Moving towards the details of the presentation, fault injection attack is one of the most powerful form of cryptanalytic attack on cipher. A single precisely injected fault during the execution of a cipher can help to retrieve the secret key in few milliseconds. Fault injection is easy with the help of some of the fault injection techniques like optical fault injection, voltage glitching, clock glitching, etc. Demonstrating a simple fault attack on a toy cipher that take 2x input P1 and P2 can have operations like key addition, sub byte, diffusion function which happens n times and the final round key addition. If we inject fault before the last round key addition, the output changes as follows that is key is visible at the output. How effective is fault attack depends on the location of fault injected and the type of fault injected. There has been a huge amount of work in the last 2 decades to find the exploitable locations in block ciphers. And from 2013 onwards, there come some of the automated tools that find the exploitable locations in ciphers. The first set of tools like XFCEXP fault and AFA which work at high level representation of the cipher and these tools find the exploitable locations along with the key bits and the attack complexity. One example of high level representation is the BCS representation which is a HTML like language. The alternate direction of research is the tools that work on software implementations like assembly, LLVM, IR, etc. and find the exploitable locations from them. Categorizing these tools into two set of classes, the first class which work at high level, we call it as HLE tools and that does sophisticated analysis and the second class call it as the implementation level tool and these tools which work at implementation and consider simple fault models. So moving towards the cipher implementation, a cipher can have multiple varieties of implementation for the same underlying operations. The implementation varies based on its applications like underlying hardware, embedded system, high speed servers, etc. For example, a toy cipher can have multiple implementations like implementation one where the order of operations is equal to that of algorithm and for implementation two where the order of functions are same but within a function the operations are interchange that is second byte key addition followed by the first byte key addition. For implementation three which is a t-table based implementation where the operations are merged like sub byte, diffusions, etc. For implementation four which is a bit sliced implementation, one byte operation in the algorithm is represented as bit operations in the implementations and the sweet spot are different for different implementations of the same cipher. Hence it becomes an onus for the user to bridge the gap between existing high level tools and the implementation level tools. As the high level tool, even though there does sophisticated analysis, they have de-mitted applications and restricted to algorithms. Implementation level tool even though they work on cipher implementations, they have considered only simple fault models and does not consider the cryptographic properties. Hence we introduce the FETS framework that work at source code level consider cryptographic properties of cipher and can handle multiple fault models. Here we have the FETS big idea that helps to find the exploitable locations in the implementations with the help of HLE tools and we would like to use the HLE tool that does sophisticated analysis and also varieties of HLE tools like XFCEXP fault are available. It's important to note that a cipher can have multiple varieties of implementations and we would like to perform a vulnerability analysis at the implementation level. Finding them is not that easy. Let's now see the complications in doing so. For this we have considered different levels of implementations of the same cipher. For example, BCS and software implementation. Each operation in BCS is called the sub-operations and each operation in the implementation is the program expression. The order of sub-operations and program expression is one to one for implementation one. For implementation two, even though they follow same one to one mapping, the order of operations are interchange compared to that of BCS. For implementation three, which is a t-table based implementation, thus operations are merged and hence it follows one to one and many to one mapping. For implementation four, which is a bit sliced implementation, the mapping can be one to many, many to many and so on. To summarize, exploitable locations in implementations are not that straightforward compared to that of output from the high-level tools. Hence we need some automated framework that can automatically find the mapping between high-level representation to that of implementation considering all these mapping cases. For this we introduce the FETS framework. To find the mapping from high-level to implementation and find the exploitable locations in the implementation, FETS consider three basic properties like completeness where any implementations of the block cipher must realize all the operations and operation within a round can be merged and the position of functions can be interchange. We have also used a model checking tool to find the equivalence between two levels of representation. Let's have a brief overview of how model checking works in FETS. We have two levels of representations like high-level representation and software implementation and we see in the size the high-level representation to some representation which is similar to that of software implementation as the first step and in the second step we add some required assertions to determine the output of P of 1 equal to state of 0. Step 3, we generate the constraints and properties and we won't be going in details of this step. Step 4, we use an underlying set solver that is to determine what is defined in the BCS is what is implemented. To demonstrate the working of FETS mapping phase, we have considered different types of software implementations of the same cipher that take care of all the properties of mapping. Let's just quickly go through the mapping phase. We have the BCS and implementation ready and it starts from the first sub-operation A1 and program expression E1 and it started tracing from this and here we use the model checking tool to determine the equivalence between A1 and E1. So, the model checker take these two expressions and determine that they are equivalent and if they are equivalent then it is added to a table called EMAP. Moving further, it goes to next sub-operations and program expression and with the help of model checker and determine that they are equivalent and this continues until all the sub-operations in BCS are mapped to that of program expression. But things are not always this straightforward. Moving towards implementation 2, where we have the changed operation, it starts from the first sub-operation in BCS and program expression and it won't be able to find the mapping with the help of model checker. Then it goes to next expression E2 and determine that A1 is equivalent to E2 with the help of model checker. Then it starts from the first unmapped node E1 and find the mapping between A2 and E1. So, this also continues until all the sub-operations are mapped to that of expressions. So, this is for the interchanged operation and for implementation 3, which is a merged implementation, the first key whitening follows a one-to-one mapping that is A1 maps to E1 and A2 maps to E2. So, moving towards other functions like sub-byte, diffusion and swab as they are merged along with diffusion function. So, model checker won't be able to find a mapping for A3. So, it traces till the end of the implementation and try to find the mapping. And once it goes further and once it reaches the diffusion function, it finds the mapping between A7 and A3 and it goes further and find the mapping between A8 and E4. So, what happens to the unmapped node? From A3 to A6. For this, we use the information flow graph that is generated from the BCS. So, starting from the mapped node A7 and trace back and determine all the unmapped nodes. So, all these colored nodes map to the expression E3. Similarly, for A8, it does the backward analysis and determine all the merged node for expression E4. So, this is how merged implementation is handled. For implementation 4, which is a bit sliced implementation, here we need to give some extra input to the user stating that how many bits are realized to a 1 byte operation. For example, here we have considered 4 different expressions are realized to 1 byte operation in the BCS. So, it starts from A1 and traces all the 4 expression that are equivalent with the help of model checker. So, similarly for A2, it finds the next 4 expressions. And for merged operation in this implementation, it also uses the information to flow graph to determine the merged nodes. So, this mapping does for all the nodes in the BCS. So, the final output of mapping phase is the mapping table that contain the sub operations and program expressions. And from the table, it's clear that the sub operations can have 1 to 1 mapping, many to 1 mapping, many to many mapping and so on. This result are for the toy cipher. So, what about the real implementations like AES? For evaluating AES, we have considered 7 different implementations of AES. And the 7th one is the bit sliced implementation. Let's see how this implementation differs. For implementation 1, where we have key whitening, sub byte, shift row, mixed column, add round key, which follows the same order of the algorithm. It has a 1 to 1 map. For implementation 2, where we have interchange of byte and shift row. For implementation 3 and 4, which is a T table based implementation, where we have merged operations from sub byte, shift row and mixed column. For implementation 6, which is specially crafted for testing the scalability of the tool. Here we have merged operations and swapped operation. And for swap, sub byte, generally we follow the order of operation from first byte to 16 byte. But here we have considered from the 16 byte to the first byte. Let's see the mapping results from this. We have the graph that shows that mapping from sub operations to program expressions. Let's go through the implementation it is. For implementation 1, it shows that a direct graph is a 1 to 1 map. For implementation 3 and 4, where we have the merged operations, the number of expressions is really less compared to that of other implementation. And for implementation 6, which is specially crafted, the second function, sub byte, which follows a reverse order. And it also has the merged operations between mixed column and add round key. For the next implementation, we have 8 different expressions in this map to that of one sub operation in BCS. After doing mapping, let's now stitch this big idea to a framework called FETS. The figure shows the high level overview of FETS. They make you solve the high level tool that does sophisticated analysis. Let's demonstrate it with some example. So here we have taken XFC tool, which gives us the exploitable locations for different ciphers along with the derived key bits. As we have the result from the high level tool, which is the exploitable nodes at the high level representation, let's map them to that of software implementation. Using the second sub module that make you solve the FETS big idea. Once the mapping is done, using the equivalence mapping module, the next sub module, find all the sweet spot for different implementations of the cipher with the help of HLE output from HLE tool. Let's be happy that we have successfully find all the sweet spot for different implementation. Is this the complete set of exploitable instructions? Well, no. There can be many instructions that can influence the result of given sweet spot. For this, we use the fault evaluation module in FETS. For example, there can be different possibilities by which fault can be induced to these expressions, like A8 maps to E9. So, fault induced in T can also have effect on the state 0. So, in order to find all this expression in the complex cipher implementation, we have used fault evaluation module that is implemented using LLVM compiler passes. The entire module is implemented with LLVM as follows. The software code along with the exploitable expression from the previous phase is converted to IR instructions and then converted to control flow graph. And each IR instruction is considered as a node and the edges are added based on the control flow. So, we have the control flow graph for with marked exploitable expressions. We have used exploitable node detection module to determine all the exploitable instructions that perform a backward data flow analysis on the control flow graph. And let's now see some simple examples. For this, let's see, assume that this node is exploitable and for finding the exploitable instruction, we have used three set called relevant set, define set and use set. For finding the exploitable instruction, we need to trace the relevant variables. Finding the nodes that can influence the result of the relevant set is marked as exploitable. And the nodes that does not have effect on the relevant set is marked as unexploitable. This is determined by backward analysis. So, from this graph, the last node defined as unexploitable and all other nodes follows can influence the result of the relevant set. So, all these instructions are exploitable. So, the final output of fault evaluation module is all the exploitable instructions that can influence the result of the given sweet spot. Finally, we have designed our FETS framework. Let's just evaluate it on different cipher implementation. For this, we have used two different high level tools like XFC and EXP fault that find the exploitable locations for different ciphers along with the key bits derived. And making use of this, we have done the mapping and found the exploitable instructions. For fault evaluation, we have considered two locations like A420 and A496 for different HLE tools and the graph shows that the exploitable instructions for these HLE tools. The brown color node shows that these nodes can influence the result of both A420 and A496. Quickly going through the evaluation results so we have evaluated seven different AES implementations and implementations like Lefia, Chamelea, etc. The table shows that the evaluation time for different modules of FETS. For example for implementation 3, the number of expressions is 196 and the size of emap is 84 and it took around 98 minutes to find the mapping. And for fault evaluation, the size of control flow graph is 4299 and the percentage of exploitable instructions is 3.71%. As we have developed the FETS framework that finds the exploitable instructions in real world implementation and that to integrated on LLVM compiler, there is an open question of fault attack aware compiler framework. This is an open problem and as a first term, we have used FETS to design a fault attack aware compiler framework by incorporating redundancy based countermeasure. And this gives us the executable with countermeasures automatically inserted. As mentioned this is the first term and for more research you can refer the paper. So the conclusion of the talk is we have developed the automated framework that determine the exploitable locations in software implementations of block cipher. And we have developed the first automated fault attack aware compiler framework that incorporate countermeasures and automatically incorporated. And the exploitable instructions varies and that too depends on the implementation and we have done evaluations on different AES implementations and other ciphers. And that's all for the talk. Thank you for your attention and please let us know if you have some queries.


Big question, should you quit your job? Well, in this video, you're about to find out. So this is a question probably everyone comes across in their life, regardless of who you are. At some point in your life, you have worked for somebody, or you are working for somebody, depending on if you are self-employed or entrepreneur, et cetera. But at the end of the day, this question is important for a lot of people, and that is, should you quit your job?  It all depends on your situation. You know, do you have a family support? Are you single? Where do you live? What are your goals are? You get it? Right, it's complicated. However, there are a criteria of questions you can ask yourself to kind of prepare yourself for the future to create a plan, because no matter what you wanna do in life, you need a plan. You wanna build a house, you need a plan. You wanna build a business, you need a plan. You wanna build your body, get in shape, you need a plan. You want a good diet, you need a plan, plan, plan.  So you need to have organizational skills or critical thinking. And so the first question I like to ask myself, or you should ask yourself when it comes to should you quit your job is this, do you find it enjoyable? That's, you know, anything you do in life, you should find enjoyable. If you go to the gym, find enjoyable. Working with your peers, find it enjoyable. So you need to ask yourself, when you go to work and at work, how do you find that process? Are you enjoying working with your peers? Are you enjoying the process of work? And when you come home, are you bringing negative energy back home? Because if you are, then this is not gonna last very long.    Not simply, oh, yeah, I don't like this situation. I'm gonna leave. No, I'm not telling you that. But this is the first question I ask from the energetic, emotional, spiritual and physical, do you enjoy working at your job? That's number one.  Is are you too comfortable in your job? See, now we're going polarities over here. Number one is miserable. Number two is euphoric. Because there is a saying as Nassim Tlaib let's say the two biggest addictions in life is number one is heroin and number two is a steady salary. And so if you find yourself in a position, and this is why there's a lot of issues in like big union or bureaucratic jobs, because it's just way too cushy and they don't wanna leave, but basically they're not learning any new skills. So ask yourself, are you too comfortable in your job? Are you learning things in your job? Are you building skills? Are you networking better? Are you moving up the ladder of your life? And a lot of people find themselves in a situation, as I mentioned, whether it's like a high bureaucratic job or a union job or other examples where they're just too comfortable and they're not moving in life. They think it's safe. They think they're playing the safe way. And there's a saying by Joseph Campbell, he who thinks he knows doesn't know. He who knows, he doesn't know, knows. And so you're not gonna really evolve or grow when you're in this position. You're pretty much addicted to this position.    You cannot adapt to the ecosystem that you're in, the economy, the everything. You cannot adapt. You're just, you're living in a like DOS mode as opposed to being update a new software. So that's a second question you gotta ask yourself. The third question you gotta ask yourself is, is this a means to an end? Everything in life has to have a means to an end. There's not finality in life, meaning you're not gonna be doing the same thing for the rest of your life, especially in this new economy. More and more things are going to gig economy. Economy is moving rapidly, skills. The number one, I would say power and this applies throughout the history of human civilization is he who can learn the fastest and adapt the fastest wins. In nature, it's not about who's smarter or who's stronger. It is who can adapt better in their environment. And so you gotta ask yourself, at your current job, is this a means to an end? If it is a means to an end, great. You already know the answer, should you quit your job? The answer would be yes, maybe so, depending on the timing. Maybe timing is right, then you leave. That was a means to an end. So you gotta analyze the job you're in. Are you developing skills for a means to an end? Is this a stepping stone position for a next position? Is this a stepping stone company for the next company? Or is this a foot in the door? You know, a lot of people leaving college university, they need a foot in the door because they have zero fucking, zero experience in life. So they gotta get some experience. So you gotta really dig in and see if there's a means to an end. There has to be a means in and everything. Everything that you do. This is not the end all to be all. There has to be something next. So that's the third question you're gonna ask yourself. The fourth question you gotta ask yourself is this. And it's an important question. Are you feeling too burnt out? Because there are amazing jobs out there where the salary is fantastic. You are learning amazing stuff. You're not status quo. The things are moving rapidly and you are just burning out. It's just you can't handle it too much. You're working 18 hours a day for whatever company and you're burning the candles on both ends. You have an amazing pay. You might be supporting your family, whatever. But how long can you keep this up? How long can you keep this up? I always say health is the most important commodity in life, health and time. It's hard to buy those two things. You can buy good healthcare. You can get access to good doctors and medicine but it's hard to reverse health. It's very hard. It's not impossible but it's very difficult. And so you can't buy time. It's very difficult to reverse health. And so these are the two things that we just throw out that's free. It's like yeah, health, forget about it. Somehow magically it's gonna come back. Time, oh yeah, yeah, yeah, time's free. Time's the most important commodity we have. It's non-renewable, literally it's non-renewable. You cannot buy back time. You can only buy future time.  It's like how long can you continue this?  And finally, number five relates to context. Remember context is key. If you have a family that you're supporting and you have a mortgage and you have kids, it's gonna be much different than if you're single by yourself living a bachelor pad. You know what I mean? And you gotta plan accordingly. If you are this individual that's supporting a family and you went through these questions, you gotta plan accordingly. And it's all about optionality. Most humans we think very binary, right? We look at an option and we see AB. We look at an option and we think there's only one way to answer this. But in reality, there's many different optionality. This is just how the mind works. We would view a job and we think, oh, I'm just gonna quit this. Or I'll give the example right now, you're killing yourself, burning the candle, both ends.  When in reality, you need to map out the options you have, right? So in the case of you're working too much and a family to support, maybe there's other options. Maybe you can talk to your boss or employer about a different position. Maybe you can negotiate, you need help. Maybe you can hire an assistant to help you because you're such a good performer. Like people like, guys, listen, companies need the best performance. If you're A plus player in a company, you're hired anywhere. Doesn't matter what trade you are.  If you are A plus people or A plus person, there's headhunters looking out there to headhunt you to bring you to the next company. Talent wins, period. Doesn't matter how much money you raise or how good your product is, talent always wins.  And so you gotta map out the optionality. That person who's a single dude living by himself in a bachelor pad, he doesn't have anyone to support. He can take big risks. He can literally say, I quit today and go somewhere else because he's not paying for a mortgage. He's not paying for kids. He's not supporting anybody as opposed to that. And the other individual has support or he is supporting somebody. So you gotta map it out, guys. Like, listen, life in general is about auditing what's going on in your life and asking really, really good questions. And it's a heuristic. It's a checklist that you have to do. You have to literally write down these questions and these are simple four or five questions, man. You can go down, you can ask yourself 10 questions. It really doesn't matter. What matters most is the process that you're going through. It's actually not the questions. It's a critical thinking process that the questions force you to think a certain way. And so you write down questions and you write down possible answers for the questions and you create a diagram. You map out what are the options that you have and then you figure out what is the best option in my context of my life? Am I married? If I'm single, where do I live? What are the opportunities I have? And this is how you approach life in anything.  These questions or the way that you approach with critical thinking applies to anything that you do in life. And I'll leave you with that, guys. It's quite simple.  And leave a comment below this video. I wanna know your thoughts like always. If you find value in this video, give it a big thumbs up, like and subscribe. The more subscribers we have, well, I guess it helps YouTube. I'll talk to you guys soon, peace. Or I like to say adios.


Welcome to NTA Nightly. I am General Norville. This edition stops stories. Nemo assists several residents who fled their homes in the aftermath of heavy rains. The Ministry of Health holds broad-based consultations on COVID vaccination and the Caricam member states to provide assistance to earthquake-stricken Haiti. Torrential rains on the weekend have caused landslides and damage to homes in a number communities. On Friday, 20th August, there was widespread flooding in the city centre, as conditions associated with a tropical wave intensified. Torrent Gustav, director of the National Emergency Management Organization, Nemo, appearing on the morning brew on the national television network, said Nemo received emergency reports concerning Marigold, Bocage, T-Rochet and Souffre. We did receive calls from individuals whose property was partially or totally destroyed. We had one instance again in the Bocage area. We have one in Marigold where the home was totally destroyed. And just this morning, I received the call from the T-Rochet area where there is a house that is at present moving due to the rainfall and landslide nearby. We are continuing to receive reports. We saw reports from Souffre where the Columbia area is impassable due to a major landslide in that area. Our district disaster committee is continuing to send in the reports as they receive them and they will be continuing throughout the day. As damage assessments continue, the island is forecast to experience more rains from the intertropical convergence zone. Depending rains, Gustav says can impact Nemo's response to the affected families. The one in Bocage, the family cannot go back into the house at all because the landslide came to the back and pushed the house off its pillars. So they cannot access that house at all. All of the property, everything is in there still. So we have assisted them. A neighbor took them in rent free for a month. And we assisted them with a few mattresses, some bedding, and some food items to assist them period that they will be at least for now. We will be continuing to liaise with them to find out how we could continue to offer that kind of support to them. The Nemo director says the public can assist in recuperation efforts through the donation of mattresses. After the passage of Hurricane Elsa, we have assisted a number of families with mattresses. As you would know, it was a lot of roof damage, mattresses, beddings. We have given a number of these out. We are short on them now. We're expecting to get a few more, but right now we're short on them. We are trying to get donations in that regard. So anyone who can assist, we will gladly... Anyone wishing to contribute to the efforts of the National Emergency Management Organization can call 468-2121 or 452-3802. And as you heard earlier, more rains are expected to affect the island. Director of Met Services, André Joillet has more on that. Any rainfall occurring today would cause flooding because of the saturation of the soils. And the models are showing that we are expected in the tropical wave to go through by tomorrow, but ahead of it, we will be having some instability. And that would cause showers from this afternoon into tonight. So persons in low-lying areas and flood-brown areas, please take the necessary precautions, like your waterways. Make sure that they are clear. And if you need to move to higher ground, please do so. In other developments, the Cabinet of Ministers will this week receive recommendations coming out of the recently held National COVID-19 Vaccination Policy Consultation. The forum drew participation from the public and private sectors, medical practitioners, non-governmental organizations, trade union representatives, the Employers' Federation, the SLHTA, among other entities. The forum discussed issues surrounding vaccines, vaccination and the legal implications. The Ministry of Health, Wellness and Elderly Affairs on Thursday held a National Vaccination Policy Consultation. The consultation brought together professionals of various areas, including that of the medical and legal fields, with a view of analyzing the current COVID-19 situation and exploring available options so as to effectively combat the pandemic. Dean of Law at the University of the West Indies, Professor Rosemary Bell Antoine, explained that the best option would be for a country to employ a voluntary vaccination scheme accompanied by the required education and persuasion, rather than a mandatory vaccination scheme. The Government of St. Lucia has clearly stated that it will not go the mandatory vaccination route and will respect the rights of citizens to choose. However, in the wider Caribbean, there have been discussions on whether governments should mandate vaccination to resume some sense of normalcy. Professor Bell Antoine said such a mandate is supported by law. I would say to you that yes, the legal framework does support compulsory vaccination or mandatory vaccination, whether we're looking at the constitution, the public law sector, or whether we look and get from the point of view of the private law sector. And so the first thing in terms of our constitutions would be to appreciate that our constitutions would look at what is reasonably required in the particular context. And of course this context, as you have heard, is one of great risks lives are being threatened by COVID. So is it reasonable then, with the seriousness of this pandemic, is compelling vaccination a reasonable option? Yes. And I would also suggest that we want to add to that because of how we see how laws developed, how cases are being developed. Is it a proportionate response? In other words, is there something else we can do that will be just as effective? And the other things that we have been doing are the PPE, etc. So it would be, is it that we have tried all of these other methods and persons still don't want to vaccinate? Then it means that we are getting to that idea that it's a proportionate response. That is a principle of law which comes into being in this instance. The Dean of Law indicated that the court would use established science to determine its legal position and not conspiracies or unproven theories. She further explained that the rights of all individuals will be considered in such instances and not just that of those who are or are not vaccinated, those who wish to be vaccinated, those who wish to remain unvaccinated and those who want to be but are unable to be vaccinated due to medical issues. Everyone's rights must be taken into consideration as according to Professor Bell Antoine, rights are not absolute and do not exist in a vacuum. And in fact, if we look at your constitution, the St. Lucia constitution, you will see not only does it speak to reasonableness, reasonably required in the interests of the society, but also it talks specifically not just of the public interest in health, as was mentioned before, but also it specifically mentions public health as an avenue for limiting rights in the public interest. So that is not so in all constitutions, but in your constitution public health is specifically mentioned. And what is even more interesting and what makes it even more plausible in terms of an adequate legal response for compulsory vaccination is that the St. Lucia constitution also specifically mentions infectious disease. Dean of law Professor Bell Antoine advised that the exploration of legal avenues is not hard and fast and should only come into play after all avenues have been exhausted. Individuals the world over have expressed their concerns and or reasons as to why they continue to refrain from taking the COVID-19 vaccine. The Dean of law examined one such reason. I understand that the COVID-19 one might be a bit different in that many people have concerns about it being for emergency use or experimental use, but the courts again have looked at these issues in the Bridges case for example they have not found it persuasive with this notion of experimental because we've had scientific trials and so on and because it's been declared safe. So that has not been a very important deterrent to any court saying that because of that you can't compel it is still in that direction. I must say that there is nothing hard and fast that court can't say otherwise but from the analogies that we have this is the direction this is a trend and what we believe to be the legal position. Of course the legal position is different to any policy decision that you may want to take but this is what the legal position would be. Dean of law at the University of the West Indies Professor Rosemary Bell Antoine. The Caribbean community Caricam is responding to the urgent needs of Haiti in the aftermath of two natural disasters a 7.2 magnitude earthquake demolished buildings and took hundreds of lives. Haiti was also lashed by tropical storm grace which caused widespread flooding more from to San King English Francis of Caricam News Time. I reiterate the community's condolences with the government and people of Haiti and to the relatives of those who lost lives in this terrible disaster. I also wish a speedy and full recovery to those of those who were injured Haiti can be assured that the community will do all it can to assist in this time of national crisis. The toll of the powerful earthquake has climbed to over 2100 dead and 12,000 injured. According to the carbon disaster emergency management agency's fourth situation report over 300 people are missing as of August 18. At least 650,000 people are in need of emergency humanitarian assistance in the most impacted areas representing roughly 1.6 million people. We do know that approximately 16 percent of the country's population has been affected and that the impact has been most felt in three of the southern departments. These are the south granades and NEAPS departments. The government of Haiti has listed water to our polling, food, medical assistance and sanitary kits as the priority items needed at this time. I've been in contact with Haiti's prime minister, his Excellency Ariel Henry, and we send theirs and I have pledged our support for the Haitian people and would have indicated that we continue to stand in solidarity with our Haitian brothers and sisters. The required humanitarian items are available for purchase in country. Now this is a very important point because Port-au-Prince is still operational which means that commerce is still occurring in country. So a principle that we operate by is that we do not wish to flood the country with relief items in a situation where the supply chain has not been broken and relief items can in fact be procured in country. So in this regard, the government of Haiti has guided that they're requesting cash donations. CDEMA has deployed members of the Caricom operational support team to Haiti to assist the country's emergency operation center in its coordination efforts. Caricom member states and CDEMA are collecting monetary donations to assist humanitarian efforts in Haiti. Tropical depression grace which dumped heavy rains in the disaster-torn country killed four people, flooded hundreds of houses and caused landslides. Tropical storm grace also affected Jamaica and the Cayman Islands, dumping heavy rainfall, downing trees and electrical poles. And St Lucia has also joined the Caricom response. The National Emergency Management Organization, NEMO, will in the coming days inform St Lucia on how they can donate to the relief effort. In keeping with changes in international oil prices and government's application of the modified market pastoral petroleum pricing mechanism, the retail price of LPG 20, 22, and 100 pound cylinders has changed. The retail price of gasoline, diesel, and kerosene remains unchanged. The price changes take effect from Monday, August 23, 2021. Gasoline and diesel remain at $13.95 per gallon. Kerosene remains unchanged at $10.06 per gallon. The 20 pound LPG cylinder decreased from $31.65 to $31.59. The 22 pound cylinder also decreased from $34.81 to $34.75 and the 100 pound cylinder saw a reduction from $219.79 to $219.26. The next adjustment of the retail price of fuel products will be on Monday, September 13, 2021. This is NTN Nightly. Primers Hutchinson is up next. Stay with us. We are working parents and we breastfed both babies exclusively. Mother's breast milk is naturally the best milk for baby. Love yourself and love your baby. Breastfeeding saves me money and it's free. Every moment I breastfeed strengthens the bond between me and my baby. I breastfed twin boys and lost all my baby fats. We are breastfed and we have breast milk power. I am Pastor Alvin and I support breastfeeding. For more information, call the Nutrition Unit of the Ministry of Health and Wellness at 468-5359. Welcome back. We join Primers Hutchinson for the NTN Nouvelle of Guéol. We are going to be talking about the National Television of the NNN, the Nouvelle of Guéol, and the Primers Hutchinson. We have a consultation with the COVID-19 patients who can come and visit. We have a lot of different organizations and agencies in the country. The consultation was held by the public members. You see. You see. Dr. Dr. Dr. Dr. Dr. Dr. Dr. Dr. Dr. Dr. Dr. Dr. Dr. Dr. Dr. Dr. Dr. Dr. Dr. Dr. Dr. Dr. Dr.


There are two different reasons people feel the need to reinvent themselves. The first is when you have to make a change. In other words, when it's not your choice. If you're getting divorced, you've got to move on. If your company goes under, you've got to find another job because you need to make money to survive. The second reason is when you want to make a change. Maybe you feel like you've been wasting your life up until now or maybe you just think, it's time for something different. What I want you to know is that regardless of which of those two categories you fall into making a change is possible. And your thirties is actually the best time to do that.  Sound good? Stick around. I'm Brian Sakawa, you are watching He Spoke Style and on this channel I give you all the advice and inspiration you need to dress well, develop your personal style and gain more confidence. So what does it actually mean to reinvent yourself? I'll tell you what I think it means, but first I want to talk about what it's not. Reinventing yourself is not an escape and it's not a way to run away from your past. We are products of our own experiences and the choices we've made and to reinvent yourself, the key is to take those experiences, take those lessons you've learned, both the positive and the negative and use them to improve yourself and to make changes that will allow you to make and live the life that you want. Now if you've decided that it's time to reinvent yourself and you've really made that commitment to do it, chances are you're very excited. You're looking forward to the change, to all the positive things that will come from it and all the happiness that you will experience as a result of making this change. But what you need to know is that it's going to take work because when it's time to reinvent yourself you have to try. The best way to overcome the challenges that come with reinventing yourself is to really know yourself and your abilities. Ask yourself and be honest with yourself about what you're good at and also what your limitations or weaknesses are. Be practical and realistic with this stuff up front so you can create the best possible scenario for yourself to succeed. So for example, let's say that I wanted to completely change my life right now and the thing that I really wanted to do was to become a professional basketball player.  Second, I'm five feet, nine inches tall. And third, I'm 44 years old. It doesn't matter how bad I might want to be a professional basketball player. It's not going to happen. And the fact that I can be honest and realistic with myself about the reasons it would never happen will save me from wasting a lot of time, wasting a lot of energy and ultimately being disappointed in the end. I'm not saying you can't dream big, but just always have that reality check in place. Another very important thing to think about before you jump into reinventing yourself is to align your goals with what really matters to you and what your needs are. If you can tap into that and be motivated by those intrinsic things, that stuff within you, then you will be much more likely to succeed and be happy than if you are motivated by some external force or what someone else wants you to do or thinks that you should do. This is huge, so spend some time really thinking about what exactly it is that you want. Now, once you've done that, it gets exciting because you can start taking those first steps. And what I'm going to do now is to take you through each of those five steps and then we're going to get into five specific strategies that you can use to reinvent yourself. Step number one is to make a plan. Not having a plan will almost always lead to failure. Now, I know we sometimes hear stories about people who just sort of wandered into something spontaneously and ended up having massive success. And those are great stories because they don't happen that often. It's very unlikely for something like that to happen, so it's not something that you should count on. Along the lines of really knowing yourself, making a plan to reinvent yourself really requires a thorough and honest assessment of your current financial situation, emotions and mental state. As I mentioned before, it's important to be practical and realistic to give yourself the best chance of succeeding. And as you make this plan, have your goal in mind, but don't get hung up on figuring out every single step that you need to take and putting them in the right order. If you do that, it's very easy to never even get started. So think about it this way. Instead of following a map, you're using a compass. You know that you're going in the right direction, but going in the right direction doesn't always mean following a clear path. Step number two is to visualize success. Now, I mentioned this in a previous video I did titled 10 Easy Ways to Be Better Every Day, which I highly recommend checking out once you're done here. I'll link right up there because a lot of those tips are applicable to being successful at reinventing yourself. Visualizing success is important because what you're actually doing in the process of visualization is training your subconscious to be aware of the goal that you want to achieve. This works because what happens is your subconscious reminds you consistently about that goal. And it gets really cool because that then trains your brain to respond as if the outcome were true in the present moment. It's pretty cool and I know it works because I do it myself.  I recommend taking five minutes every single day. Maybe right when you get up in the morning. It's not a lot of time, but it is time well spent setting yourself up for success. Step number three is to set realistic goals. I sort of already touched on this with my wanting to be a professional basketball player example. So we don't really need to get too deep into that. But what I want to add is that setting a realistic goal doesn't mean you can't aim high. Please don't think I'm saying you have to go from one menial thing to another because that's not what reinventing yourself is all about. Just understand that the higher you aim and the loftier your goal is, the harder you are going to have to work to make it happen. Step number four is to develop positive habits.  When you're in a groove, you want to stay in that groove because it's working for you and you're seeing the benefits firsthand. I always like to use the example of exercise. You know, when you commit yourself to a daily exercise routine, you get to a point where your body kind of craves it. And if you miss a day or two days, you really feel it.  Now, it's great when you're in that routine, but getting into it can sometimes be a little difficult. And since we're talking about reinventing yourself in your 30s, which implies that you're aging a little bit, let's talk about a simple positive routine that you can start right now that will help you look and feel your best as you transition into this next chapter of your life. I'm talking about skincare and particularly Tish Hanley's skincare system who I'm proud to partner with for this video because they make it super easy to get into that routine. And speaking from experience as a Tish Hanley user for over a year and a half now, this stuff actually works. So if Tish is new to you, all you really need to get started is their basic plan. That's a face cleanser, an exfoliating scrub, AM moisturizer with SPF to protect your skin from the sun, and a PM moisturizer for the important repair process that happens while you sleep. Personally, as a 44-year-old guy, I'd recommend going with Tish's level three system which adds in a firming serum and an eye cream. Now, I mentioned that Tish makes it super easy to get into a routine and here's what I mean. When you get that box in the mail and you open it up, there's a card and that card tells you what to do. It tells you when to do it and it tells you how much of the product to use. Add to that when you subscribe. You don't even have to think about going out to get some more when you run out because it automatically comes to your door every month. So in addition to great skin, when you join Tish, there's lots of perks as well, including at least 20% off the retail price, the ability to customize your box, shipping reminders, pause or cancel at any time, no hassle refunds, free US shipping, as well as low-cost shipping to most other countries.

So click that link to get started today. All right, so that brings us to step number five, but I want to leave that one to the end and you'll see why. So instead, what we're going to do is to jump into the five strategies you can use to reinvent yourself in your 30s. Strategy number one is to step outside of your comfort zone. If you're planning to make a change as big as reinventing yourself, it is so important to be open and willing to break out of the safety zone that you've created for yourself. Hey, it's real easy to kind of sit back and be where you are. But if you're ready to reinvent yourself, sitting back and being where you are is not what you want to be doing. If you're going to completely change things, be prepared to be a little uncomfortable, but use all those situations as learning experiences because you never know where you're going to end up. I started this business just under 10 years ago and for that, I didn't have photos taken all the time. I never talked to a camera and to be honest, felt really weird at first, but I looked at it as a challenge, as something new, as something to get better at because in order to achieve the vision I had, which was to help as many guys as possible, dress well, gain more confidence and achieve their goals, it was something that I needed to do in the medium that I was working in. It wasn't easy. It was definitely outside of my comfort zone, but I kept at it, I kept working at it and I'm glad that I did because it has really helped me create a completely new life for myself. Strategy number two is to change your style. Hey, you're reinventing yourself, new life, new look. All I'm saying is it can't hurt because if there's one thing and if there's one truth about clothes and your appearance, it's that it has an incredible power to change how you feel about yourself as well as how people see you, right? I mean, you've probably heard before, dress for the job that you want, not for the job that you have. So when it comes to reinventing yourself, consider some style changes to help put you on the path that you want to be on. Strategy number three is to learn something new. If you're really trying to reinvent yourself, you've got to make some big changes. Don't just incrementally tweak something here and there thinking that eventually you'll get to where you want to go. It doesn't work that way because if you're just doing little things here and there, it's going to always feel like it always felt. What you need to do is, is to turn everything upside down like that. Try something completely different, something you never thought you'd do before or maybe reconnect with something that you used to love doing but you haven't had time for or haven't made time for. The most important thing is that whatever it is that you choose to do that you enjoy doing it. Reinventing yourself is all about making changes that will lead to a more positive and happier life with a greater sense of purpose and fulfillment. And if you don't love what you're doing, none of that's going to be possible. Strategy number four is to accept changes. Change is one of the only constants in life. Things are always going to be changing and how you respond to those changes will determine your outcome. So accept them and channel that energy into something positive.  Optimism will take you a very long way especially when you're able to turn something negative into a positive. Strategy number five is to not fear failure and actually be ready for it. The one thing that all successful people have in common is that they have failed and they've probably failed multiple times.  What you're not seeing is the number of times they've failed to get to that point but successful people are not afraid to fail. A failure is an opportunity to learn. A failure is an opportunity to get better. A failure is just another step on the path to success. Reinventing yourself. Things are going to change. Things are going to feel uncomfortable. Things are going to be new and with all that stuff going on there will be some failures. But if you accept it and use it as a way to go forward you will be successful. Which brings us to perhaps the most important part of this whole process. Step number five to reinventing yourself. So what I'll say is if you've gone through all these steps if you've made a plan you visualize your success set realistic goals develop some positive routines none of that matters unless you do something about it. Start now. Things don't have to be perfect. In fact thinking too much about perfection is something that will always keep you from taking that first step. I remember when I was in grad school and I was in this class that I had to write a lot every single week. Now I'm the kind of person that generally needs to map out everything before I do it especially when I'm writing but I would get so bogged down in making that outline and trying to figure out every single detail that I would just kind of like freeze up and it became very difficult for me to write anything at all. The advice my professor gave me was to just vomit on the page. Just start writing. It will come to you and you will be able to piece it all together. And you know what? He was right and just starting is the most important step.

The peace and unity of the Calabari people of river state remains a paramount on each or leaders across the Niger Delta must work tirelessly to ensure a peaceful coexistence among Aizan's and other ethnic nationalities. This were the words of the President of the Movement for the Survivor of Ethnic Nationality in the Niger Delta, Mohsen de Comrade, Canada West during the procession for the final rights of the King of Calabari Kingdom, his Majesty Professor Tufelus Princewill. Addressing newsmen after the rituals in the streets of Potarko, the river state capital, West said that the late King was known across the Niger land for his peace of disposition and his hospitality, and has left the world in legacy with all which all the Niger sons and daughters must emulate if they must move forward. With vision, carrying every community within the Calabari Kingdom alone. Dialogue, round table discussion, continue to jaw jaw, even great wars always end up on the round table. Not that there is an argument and then one is in a dagger drawn battle which usually ends the communities in total disarray. So many communities have run almost extinct because of that kind of, you know, very violent disposition, unforgiven spirit, couldn't tolerate one another, lack of consideration for one another and all of that.

Coming up on D T N S solar charged headphones could mean endless battery life. The numbers show that tick tock is the Facebook threat you've been waiting for and VR gets productive and good for your health. Sarah Lane's fitness VR regimen is indicated. This is the Daily Tech News for Wednesday, April 14th, 2021 in Los Angeles. I'm Tom Merritt. And from Studio Redwood. I'm Sarah Lane from Salt Lake City. I'm Scott Johnson. And I'm the show's producer, Roger Jane. We were just talking about baseball stadiums, among other things. Get that wider conversation. You never know what we're going to talk about on good day Internet. Become a member at patreon.com slash D T N S. Let's start with a few tech things you should know. Samsung announced its next Galaxy unpacked event for April 28th at 10 a.m. Eastern time. The event announcement promises the most powerful galaxy is coming. So conventional wisdom is that it's not a phone announcement and the image looks slightly like a laptop. New Galaxy books, perhaps. Maybe. Back in March, we talked about Microsoft releasing patches for four newly discovered Microsoft Exchange vulnerabilities that were being actively exploited by an advanced persistent threat group believed to be hafnium. The attackers were exploiting the vulnerabilities to install web shells. Web shells give them access to targeted networks. The patches closed the vulnerability but of course wouldn't remove the web shell once it was installed. So Tuesday, the US Department of Justice announced it received approval from a court in Houston to copy and remove web shells from hundreds of Microsoft Exchange email servers. Now they didn't get all of them out there, but they got a bunch of them. The FBI conducted the removal by accessing the web shell and issuing a command to the servers to remove it. The method only removed web shells that did not remove any other malware that might have been installed through the use of the shell, but it's something. Amazon announced second generation Echo Buds, which are 20% smaller than the originals. IPX4 rated and offer twice as much noise cancellation as the originals, although they no longer use Bose's active noise cancelling technology. The new wireless headset ships May 13 for $119.99 with a USB-C charging case or $139.99 with a wireless charging case. TCL announced the 6.67 inch 20 Pro 5G Android phone, which features its in-display fingerprint reader, is coming to Italy, Portugal and the UK for 549 euros and eventually to the United States, though they didn't give pricing and a date for that yet. Budget versions, the 20L and 20L Plus also coming to those countries without 5G or wireless charging. That's why they're budget. And TCL announced its combined foldable and rollable phone tablet concept that CNET talked about back in March is called the Fold and Roll. Like with a little N with an apostrophe mark. The Fold and Roll. Still no plans for a release on that yet. Just concept. You may have heard Coinbase issued a direct listing on the NASDAQ Wednesday with a reference price of $250. Instead, it opened at $381, instantly up 52%. The cryptocurrency exchange's stock continued to rise through the day, making it one of the most successful recent tech IPOs, partly because it was already profitable. It closed its first day at $328, so it settled down a bit, but still a pretty good showing for the first day. Coinbase's future rests on the future of cryptocurrency in general. Alright, let's talk about the next big threat to Facebook. What is it, Scott Johnson? It's the thing I look at when I'm in the tub. Alright, as part of a leaked pitch deck to advertisers, TikTok claims to have more than 100 million with an M US monthly active users. That's just in the US with 732 million on a global scale with 59% of users under the age of 24 and 17% ages 13 to 17. So the Youngers. The company claims 47% of users have bought items seen in TikTok. I'm one of them. I did it once. With its US ad business growing over 500% in the last year by comparison in quarter four of 2020, former king of young people, apps with Snapchat, you may remember them. They had an estimated and now sounding paltry 46 million monthly active users in the United States according to market data from Statista. That's less than half of TikTok's numbers if you do the math. If the TikTok pitches numbers are accurate in an online survey, Statista performed last fall. 34% of US teenagers said Snapchat was their most important social network with TikTok in second place with 29%. Yeah, so this really struck me. I mean, the article on Business Insider talking about this leaked pitch deck was mostly about plans for e-commerce. And that's all very important because e-commerce is definitely how ByteDance is making money off Duyen in China and will probably be able to make a lot of money off TikTok with as well. But these numbers, these numbers are, these are Facebook in its younger days numbers. These are when Facebook was for young people, you know, for college age people back in the day numbers. I mean, you've passed Twitter. You're well ahead of Snapchat. You're on the way to being a billion user worldwide phenomenon. And that's launching you into Facebook territory. As we've talked about before on the show, Facebook kind of for the olds, you know, the young people show on Facebook to talk to their parents and their grandparents. Yeah. I mean, it wasn't that long ago that Snapchat burst on the scene and, you know, all the headlines were like, Snapchat is for 16. Oh my gosh, the youth. You know, this is, this is scary, scary app. And it's all secrets and ephemeral, right? And, and then I kind of was like, Snapchat is pretty fun. And then I sort of fell off and because I didn't have enough friends on Snapchat, but I realized a long time ago, Snapchat is not for me. But young people, you look at the numbers, it's still very, very popular. However, when you compare 46 million monthly active users in the US, that's Snapchat's numbers, to more than double that for TikTok. Again, I mean, this is a leaked tech. So just assuming that the leaked tech numbers are accurate. I mean, TikTok is blowing Snapchat away. And the fact that more US teenagers who were polled, and it was under 10,000 teenagers, it was an online poll.  But for more teenagers to say that Snapchat was their most important social network, that was last fall. I wonder if the poll was done today, how much things have changed in half a year. Yeah, I would think so too. But I would also argue, I mean, again, this date is really hard to gather and get. But I know so many people who are not in that age demographic who love TikTok. I know a guy who's 56 years old and his favorite thing to do right now at the end of the day is sit on the couch with his wife and compare their public feeds. There's something about that algorithm that hits everybody if they give it a chance. And I'm not, you know, this isn't me saying, yay, rah, rah, TikTok. I just think they found this magic sauce in the algorithm in how it works and a, you know, critical mass of people. They've built something that's very quickly becoming more important than some of these other services and doing it in record time. And that's just crazy to think about those numbers. Yeah, I mean, obviously there's, there's, you know, it's a huge swath of TikTok numbers is people younger than us. However, I was at a barbecue over the weekend and, you know, we're all talking about TikTok and, oh, you know, we're sharing animal videos. And there was someone who's just like, I just haven't gotten on there yet. And we all kind of looked at her like, you're really missing out. It's really fun. And I'm not always the story, right? I can remember that conversation about Twitter, about Facebook, about Snapchat. Now it's about TikTok. But TikTok seems like it's got the momentum. It has gone from me thinking like, oh, musically, that's the thing for kids to lip-sake. Oh, TikTok, a little uncomfortable for me to watch because it's mostly young people dancing to be like, oh, no, I think I could learn Korean by, you know, watching a certain section of TikTok. Yeah, exactly. This is a cool one. Urbanista, if you haven't heard of the company or Urbanista announced something very cool. It's latest wireless noise canceling headphones. The Urbanista Los Angeles, the name of the headphones, it doesn't really have to do with geographically Los Angeles. They can charge the battery inside with any kind of light, promising, in the company's words, virtually infinite playtime. The headphones have power foil solar cells, which promise to add three hours of listening time, one in bright sunlight for just an hour, two hours of listening time on a cloudy day, and the headphones will also charge from ambient light indoors, but charge fastest in sunlight. So you might want to leave them near a window if you're trying to charge them up without being outside. They can also charge over USB-C, so it's solar, but also power, if you got to go that route. And Gadget points out that JBL tried to crowdfund power foil solar headphones back in 2019, but had to cancel the project partly due to COVID-related travel restrictions, just bad timing all around. Power foil was developed by Swedish company Exager. It's screen printed on flexible plastic and uses principles similar to photosynthesis to generate electricity from any source of light. Partly, this is because there are no conductive layers blocking photons. Urbanista Los Angeles headphones can be used in other cities besides Los Angeles on Windows, Android, and iOS, and work with Siri and Google Assistant. Like most wireless headphones these days, they pause playback when you remove them from your head and they look pretty nice over the ear headphones. You can get them for 169 British pounds when pre-orders begin. Yeah, so this is a big advance and power foil is really interesting to watch because if this takes off with Urbanista, it might prove the technology for other platforms to pick up. And the big advantage of power foil is that it can work in situations that other solar panels don't. It can work at angles better than other solar panels. It's a single cell, so you don't have a lot of the seams and stuff. And that's what makes it work in a headphone situation where you can just flexibly put it over the top and get enough charge out of ambient light to make it worth implementing, but charge really well. I mean, three hours in one hour in bright light outdoors, even two hours with the cloud cover, like you were saying, that's impressive. And we've talked a lot about the idea of wireless power. This could be a type of wireless power if the only time it doesn't charge is when the lights are off. Yeah, these are massively cool. Also, 200 bucks if you translate the dollar to dollars. It's not bad. Like you're going to pay that for competing products anyway. Yeah, or more price for those. And if they sound great, that's a big kicker. Obviously, we got to see how they sound. I just want to mention one other thing. I think I noticed a new naming trend on the internet. You guys, we just talked about Statista. Now we're talking about Urbanista. What's with the East? Statista's been around for a while, though. I don't know how long Urbanista has been around, but you may be on to something. Oh, it's a new flicker. They're putting they are at the end. Everyone's going to put Easter on everything. I'm excited. I want to address JSC 315 says you really shouldn't be moving solar panels. So I don't know if it's something that will last more than a few years. These solar panels, because of the way they're constructed, handle moving very well to the point that the solar panels generally outlast the device they are on. Parts of the actual headphone wear out before the solar panels. Again, that's one of the advantages of Powerfoil is very durable. All right. Facebook announced several updates coming to the Oculus Quest in version 28, V28 of the headsets OS, wireless connections to PCs, and 120 Hertz come into the Oculus Quest 2. The 120 Hertz refresh rate will only work on supported games and will not be brought to the home screen. So it looks like it's there mostly for streaming VR from the PC, which you can do with Oculus Link. But you can also now do it from your PC wirelessly over your local Wi-Fi network. A wireless version of Oculus Link called Air Link will be built into V28 of the OS, requiring V28 of the PC software to work as well. But once you've got both those going, you can use it. Air Link is in the experimental stage. So for it to work, you'll need an Oculus Quest 2, a secure and un-congested local 5 GHz AC or AX non-mesh Wi-Fi network. So it's not going to work for me. And ideally, you need to be within 20 feet of your Wi-Fi router when you're using it. So it's very early days for this, but it does work. Facebook also recommends connecting your PC by Ethernet to the router so that your PC isn't using up Wi-Fi, that less congestion. There's also a list of hardware recommendations. Facebook also announced an update to Infinite Office. That's its collection of productivity features coming to VR. This update lets you connect compatible Bluetooth keyboards starting with the Logitech K830 to the headset. And then a 3D model of the keyboard can show up in the virtual world you're in and you'll be able to see your hands typing on the virtual keyboard but actually be typing on the real keyboard. The idea for now is to put a virtual desk on your real desk and then let you interact with all of the Oculus Quest productivity apps like the browser, I guess, but more to come, I'm sure. This new feature will work on the original Oculus Quest as well as the Oculus Quest 2. And all of this, of course, requires you to turn on beta features and get V28 of the OS, which is on the way soon. I'm genuinely excited about this. Sarah and I are both Quest users. I've got a one, you've got a two. No, I have a one. Oh, that's right. We both have one. Tom has the two, although he never talks about using it. Do you feel, Sarah, you tempted it all to go, oh, well, now that we're at 120 hertz and all this extra stuff and virtual keyboard, is it time? Very much so. And we'll continue to talk about it on the show. 72 hertz is as good as my original Oculus is getting. And I still think it looks like magic. So the better it gets, the better it is. And the Oculus 2 is just sort of smaller and has a couple more bells and whistles. I don't play PC games. So the idea of being untethered to free myself to be fully wireless is a little bit lost on me personally, but I understand how important it is to a lot of folks. The Oculus link has been something that people were like, this is awesome. In fact, you, Scott, were telling me how by using that I could get like more beat saber songs back in the day. When I was first getting used to this, but you were like, it's a little bit complicated, need a PC. And I was like, ask her. I don't even want to do that. So this is just one step closer to what people are going for and be able to play the sort of stuff that they've been playing on a PC. Infinite Office, I've played around with a little bit. I look forward to this. I'm not totally sure how much this would be of productive use to me day to day. But again, I also didn't think I would like VR. So there you go. Yeah. It's a really interesting thing in the concept of you being able to say access the PC version of that game with 120 Hertz support, which it has on PC or at least it does on some headsets. I think the vibe and maybe the, I forgot the one that valve makes anyway. Those that experience in theory could be yours and wirelessly or at the very least through that link cable again, which will probably ensure that you get the 120 Hertz refresh rate. So it's a little weird though, right? It's kluji. It's like, well, on the one that I have this game, I own it. I bought it and I've bought it twice. And I'm kind of playing it over here because the refresh rate is better and have more access to songs. But I kind of want to go on the road with it. And I need to take that version of the game with me. And I mean, that starts to get weird, just a little bit weird. But I really like that they're branching this out and making more stuff possible. I'm all. Yeah. It's all stepping stones, right? Eventually you want everything to be on the device. But until then being able to get some from your PC, you know, expands the capability. Eventually you want to use your VR headset as a monitor. But until then, you know, being able to use the browser with the Logitech keyboard, that's kind of cool. Eventually I just want my Oculus headset to be solar powered like that. Like those headphones. So I never have to charge it. But, you know, we're not there yet. We'll just all be walking around in the sun. Yeah. More battery, more battery. Folks, we got some more VR news to come. But first, we love to hear from our supporters. It really helps us improve the show. The show is as good as it is now because you keep telling us what you want. So if you have some time, please fill out our latest survey. Let us know what about DTNS is working for you and what is not. Just visit dailytechnewshow.com. Well, I'm always talking about how I love VR because it's the best way to work out. Not everybody exercises and uses VR exercising apps. But for those of us who do, it's very fun. And today I feel vindicated. Yesterday, the Verge's Nilai Patel interviewed the co-founder and CEO of Within, which is the company that makes the VR fitness app Supernatural. Supernatural is far and away my favorite app. I love it so much. I'm going to play it off to the show today. Chris Milk on the Decoder podcast last week talked to Nilai about how Supernatural came to be. And it's kind of an interesting path because Milk made a name for himself directing music videos. He was working with Kanye West and all sorts of really, really big names in that entertainment industry. He was also creating digital experiences and museums and was kind of interested in immersive entertainment. And that's exactly what he and his co-founder Aaron Coblin, who was formerly of Google's Creative Lab, started doing when they founded Within back in 2014. They wanted to kind of figure out how does entertainment like music or film turn into something that is a VR experience? They said, Milk says that they pivoted to exercise as entertainment back in 2018 from what they were kind of doing the first time because they both hated working out and they wanted a solution. And they were like, wait a second, why don't we just make that the company? So there's that. What's interesting about Supernatural specifically, and I've always wondered, so that's why this interview was very interesting to me is music licensing because the music is, it's very good. It's very top 40 to the point that it blows other apps away completely. I mean, unless you're talking about Spotify or Apple Music, you just don't get this kind of library in other apps, even something like Beat Saber, which Supernatural is very often compared to because it's kind of a rhythm game. In February, Supernatural signed a deal with Universal Music after signing deals with Sony, ATV, Warner Chappelle, Cobalt, and BMG as well as label deals with UMG and Warner. Milk wouldn't really go into specifics in the interview of how that all happened, but he said it was incredibly and continues to be incredibly complex and that he definitely used his contacts back in the entertainment industry to broker some deals. My first reaction to that last bit is this is the problem with trying to protect old business models. Is it makes you inflexible in adapting to new ones? Think how much money these companies could be making if it was easier for all of these VR exercise apps to license their music. And music companies are doing better now because Spotify finally was allowed to lead the charge and now you've got Tidal and Apple Music and all the others bringing in streaming music. This is the next wave and instead of keeping copyright licensing so complex that it's hard to make a deal and that Supernatural is the exception, not the rule, they could be raking in money. But I digress. I love this idea that VR, you know, another use for VR beyond gaming is fitness, is exercise. I think it absolutely is. It absolutely is. If you don't want to wear a headset, you know, on your face while you're exercising, okay, that, you know, maybe it's not for you, but I cannot tell you how much and I know I'm not alone because I like I'm part of their Facebook group and stuff now.  When I say play, it's, I don't really have a better word for it. I use the app at least five times a week. I would not go to the gym five times a week. And listen, this is not a full gym. It's mostly cardio. And Scott, you got me hooked on Beat Saber back in the early days when I first got the quest, which was not even a year ago. And I was like, this is pretty fun. Yeah, rhythm game. I like it. But then when Supernatural came along, I was like, oh, this is like an actual workout. You're not lifting weights.  So, you know, it's, it's not going to bulk you up necessarily, but it is quite the workout and it's focused on exercise.  And there are lots of other exercise apps. I haven't tried all of them, but that is, I think, I mean, it's, it's the killer app for VR. It really is. And I think anyone listening to this being like, what are you even talking about? That's how I felt until I tried it for the first time. And I was like, oh, this actually makes me like want to exercise rather than have to exercise. Well, plus those things. You need to be wireless for that to happen. Right. And the music. And the music is inexorably connected to fitness. That's just, that's the way it is. We work out to music and, you know, if you go to a spin class, music is blaring for the whole class to hear as they're ripping through that thing. And even if they bring their own sounds, they've got their own music. So you can't take music out of the equation. Not only that, headsets are only going to get smaller, smaller, more compact, more light, more conducive to them being workout ready and not big and bulky. So they got to get on board now. Or they, like Tom said, are going to miss the boat because they keep fighting it. Well, you may have heard there was a record broken recently and the record was broken by the Twitch streamer Ludwig Argen, Argen rather, who ended his nonstop stream after 31 consecutive days breaking the record for most pain subscribers with over 282,000. Ludwig started the stream planning to add 10 seconds to the live stream for every new subscriber and he said he would donate $5 for every new subscriber added on the last day to charity. We don't exactly know what the final tally was, but, you know, it was, it was an interesting 31 days indeed. After wrapping up his record, Argen tweeted, since I started streaming, Prince Philip died. The Suez Canal got blocked and unblocked. David Dobrick made two apology videos and Jesus of Nazareth died and then rose from the dead. Easter happened, right? Wow. That's really impressive. The Suez Canal one is the one that turned my head the most. That felt like that lasted forever and that all happened during the time of 31 consecutive days of streaming. So yeah, sure. At first I was like, what, I mean, was he like insane at the end of it? I mean, he was sleeping and then he kind of had like a small team of folks. Hold on, hold on. Sleeping in a race car bed. In a race car bed. A red one in the shot. Yeah.  So there were things that they were doing to allow him to be a human, but the stream went on 31 days. Yeah. That's impressive. I've heard of these sorts of things before and they don't work so well.  I think he had a good plan and he pulled it off. I say, I say, well done to this guy. Do we know what charity he was donating the proceeds to? Um, let's see. Twitch addiction anonymous. Just kidding. That's not true. I don't know. Actually, it doesn't say. It is not yet known how much he raised and the BBC article doesn't say which charity. So though I'm always, you know, I'm not, I'm not accusing Ludwig of anything, but I'm always more supportive when we know exactly where the money is going, where the money is going and all of that. By the way, if you're wondering who held the previous record, it was Tyler Blevins, otherwise known as Ninja, who had 269,154 subscribers, still a lot. But, uh, but we have, we knew we have a new champ everyone. So which nascent Microsoft streaming service will Ludwig Ogren be? And then come back after a while. I don't know. All right, let's check out the mailbag. This one comes from Matthew, who says good morning. I mean, good morning, Matthew, to you, most wonderful people and happy spring greetings from the UK. Good to hear that, Matthew. Matthew says, just got a quick question. Tom mentioned in the Monday conversation that he has a Harmony Hub, but he hasn't touched the remote for a long while. Matthew says, my question is, how does he start, stop and skip and fast forward and all that stuff? Yeah. So I wrote directly to Matthew and long time listeners of this show know that I suffer from a malady known as liking the Apple TV remote. There is no cure. I just like the remote. And so for stopping and starting and actually for stopping and starting, I can use voice and I do sometimes. But mostly I use the Apple TV remote or the Roku remote. The Roku remote sitting out there as well. We do tend to use the Apple TV a little more than the Roku and certainly for fast forwarding and stuff. So, yeah, I do use fewer devices, right? Because I don't need to use the remote for the TV.  Or with the Apple TV and the Roku both now, they use Keck, so I can just press a button and they will turn the TV on to the right input. The speakers automatically pick up where the input is coming. Occasionally those JBL speakers don't catch up and I may have to pull out the JBL remote. So I know you're mentioning a lot of remotes and it may sound like, why aren't you just using your universal remote? And the fact is I use them so infrequently that keeping the remote settings up to date with the latest devices became more trouble than just having that remote sitting out. Yeah, that makes sense. Whenever I use that remote and I love that you back that remote so much because I don't think anyone else will. So you're fighting a good fight and it's important. Oh yeah. No, I'm wrong. I just want to say before you email me, I am absolutely wrong to like that remote. But I do. I love the Apple TV as an overall device and the experience. But that remote, I feel like I'm disarming a bomb every time I pick it up and use it. And then I'm very careful putting it down very gingerly on the table. Nobody bump it or else we're changing channels and you don't want that and kind of annoys me. But every time you back its cause, I don't know, I feel like an angel gets its wings. I am physically incapable of picking it up right side up, physically incapable. It's almost like the universe has it out for me. I mean, I'm not going to talk about it slipping between my couch cushions because that's a whole another ball game. But there's something it's as if it's secretly weighted in a way where I always pick it up upside down. Yeah. Just maddening. I don't know. It's just one of those things. Yeah. It needs to be like triangular shaped or something like that. I don't think you're going to get a new Apple TV remote this year. That's that's all signs point to that. I'm not the only one who complains about it. So let's here's hoping. Yeah. I'd be shocked if they didn't do that this year. It'll be a big deal. Well, they've shocked us before. That's true. True. Thank you for the email Matthew. And if you have any feedback of anything we've talked about on a past show question about a future show or anything in between feedback at DailyTechNewShow.com is where to send your correspondence. Shout out to patrons at the Grand Master Levels including Carol, Dustin Campbell and Andrew Bradley. By the way, very special thanks to Andrew Bradley, who is in the top lifetime supporter list for DTNS. Thank you, Andrew, for all the years of support. We love you. Also, thanks to Scott Johnson, who we also love. Scott, what's been going on since we saw you last Oh, well, thank you for saying so. We're a second week into this Kickstarter for my card game. If you want to see progress on that, I just put up a video today or it will be going up today where I go through a couple of cards and how they work and now it affects the card game.

Hi, I'm Aastha. I'm a physicist and currently doing my PhD in Solar Hydrogen Generation at the Research School of Electrical, Energy and Materials Engineering at the Australian National University. In this module, you'll be learning a lot about waves, different kinds of waves, mechanical waves, light waves, sound waves and how to use the properties of waves to make calculations and prediction as well as different applications of waves. A good understanding of waves and its concepts can enable a field of science such as optics, sound engineering which can lead you to entertainment industry or a lot of medical applications, civil engineering, mechanical engineering which will help you in building your bridges, buildings and all these kind of things. Knowledge of waves would really help you have an upper hand in any of these fields or a lot of others where you go. The goal of my research is to develop low cost solar hydrogen generation systems and I'm basically using solar energy to split water into producing hydrogen fuel and oxygen. Now the oxygen that you get as a by-product can again be used in a lot of industrial applications making it a total green and profitable system to produce hydrogen fuel. I'm specifically looking into silicon based systems owing to its popularity in solar photovoltaics. To create this, I combine my knowledge of semiconductor physics, electronics, quantum mechanics, a bit of chemistry and a lot of calculus. I mostly do a lot of experiments in the lab trying to develop these systems for low cost hydrogen generation and analyzing and collecting the data. I also do some theoretical models where I try to develop these models on my laptop and see how they want to behave in different kinds of conditions. This helps me understand the realistic behaviors of the system and try to design more appropriate and high efficiency systems. In this module, you will get a good understanding of basics of waves. It was first put together in 2016 by Joe Hope and Ed Sevik. Based on the feedbacks from students and teachers, I reviewed the module and made some modifications to make it better for you. I'll leave Joe and Ed to introduce themselves to you in the next video.


Deep learning, DL, approaches have shown great potential in plant growth monitoring due to their ability to accurately classify images and extract relevant features. However, there are still many challenges that must be addressed before these approaches can be widely adopted. These include the need for large amounts of annotated data, the high computational requirements of training models, and the difficulty of extracting both spatial and temporal features simultaneously. Despite these challenges, DL approaches have made significant progress in the field of plant growth monitoring and will continue to do so in the future.
