Hey guys, Matt from Mystery History here. So today I wanted to share with you a confession. A confession by this man. His name is Dr. Allah Shaheen and he is one of the world's leading Egyptologists. He is also head of the Cairo University Archaeology Department. He rubs shoulders with top Egyptian government figures and members of the Egyptian state of antiquities. If anyone knows about Egypt's most iner kept secrets, it's this guy. In December 2010, he was hosting a conference to a select group of delegates about ancient Egyptian architecture, when he let something slip. He admitted to being complicit in the covering up of an astonishing secret. He has since retracted the statement and is now denying he ever made it, however, during the conference a handful of press reporters were present. They all ran the same story, shortly after the conference all quoting the same remark, making it rather difficult to believe that he didn't actually say it. In what I can only imagine was a misjudgment of trust, when questioned regarding the possibility of alien involvement in the construction of ancient Egypt, he not only confirmed this to be the case, but confessed to knowing, and I quote, there is still something inside the pyramid that is not of this world. In a previous video I shared how the tomb of Osiris, once believed to have been a mythical god from Egyptian legend, a belief Egyptian antiquities would like to keep alive, was actually discovered recently. The tomb was found by traversing an access tunnel system just a few inches in diameter. From the moment this impossible access passage was discovered, they quietly knew they had found something amazing. The moment Egyptian authorities finally managed to get a robot with a camera into the tomb, a complete media blackout descended upon Egypt. Walls were constructed around the tomb and no information regarding the find was shared for several weeks. When the world was eventually allowed near the site, the tomb was found to have been conveniently empty. No explanation as to how grave robbers could have possibly got into the tomb has ever been produced. Was Osiris an alien? Was our previous research bang on the money? Even an Egyptian legend, the figure known as Thoth, was said to have allowed beings such as Ra and Osiris to exist in our realm. Were ancient Egyptian artists accurate in their depictions of these beings as hybrids? If as Dr. Alashahid states, along with ancient Egyptian literature, that there is indeed something otherworldly under the Great Pyramid, could it really be a portal? And if it is, why hide it? Regardless of what it is, they are definitely hiding something. What otherworldly thing do you think is hidden under the Great Pyramid? Let us know in the comments. Thanks for watching guys, until next time, take care. Most people have never heard of Pareidolia, but nearly everyone has experienced it. Anyone who has looked at the moon and spotted two eyes, a nose, and a mouth has felt the pull of Pareidolia. It's the imagined perception of a pattern or meaning where it does not actually exist, according to the World English Dictionary. It's picking a face out of a knotted tree trunk or finding zoo animals in the clouds. German design studio on Formative is undertaking perhaps the world's largest and most systematic search for Pareidolia. Their Google Faces program will spend the next few months sniffing out face-like shapes in Google Maps. This phenomena of seeing faces was also attributed to the very famous face of Sidonia that was found on Mars. The face was first imaged in detail by the Viking I and Viking II orbiters. 18 images were taken by the orbiters. Viking I launched on July 20, 1976 and Viking II orbited Mars on July 25, 1978. The striking likeness the apparent natural formation had to a face allowed the image to quickly gain notoriety around the world. The possibility of ancient ruins being on Mars is not a hypothesis held by modern science. And it is certainly not a scenario that NASA endorses. Neither does any other space-going nation appear to have any interest in investigating the possibility. Many conspiracies have surfaced over the years regarding covert operations in search of exactly such ruins on our neighboring planets. Many claiming black operations have occurred, such as an Apollo 20 program, with some rather convincing CGI hoaxes subsequently being created. Regardless, what a number of authentic researchers have managed to accomplish by just studying imagery of Mars and also of historical knowledge of the region held here on Earth is quite remarkable. An orbital imagery of the Sidonia region of Mars have attempted to debunk the face as just being a product of light angle. However, thankfully people did not let these debunking efforts dissuade them from further investigations of the area. Some researchers who were versed in the works of Zachariah Sitchin connected the location to the possible burial site at King. Recorded within the 10th Sumerian tablet, Sitchin had apparently translated a passage regarding a god known as Alalu, who requested upon death to be buried where he would be able to peer into space gazing upon Earth forever. Although many claim Sitchin's vague understanding of the writings may have led to mistranslations, Sitchin became convinced that this 10th tablet also laid claims to King being the constructor of the pyramids. People who knew these fragments of information actually connected a network of apparent extremely ancient pyramidal ruins resting very near to the face. These remnants of once great structures undoubtedly align with the star constellation of Pleiades. What is astonishing is that these ruins would not have been discovered without Sitchin's translations. Was Sitchin right all along? Is this really proof of ancient ruins on our nearest neighbor? The alignments are certainly compelling and must be more than just coincidence. As always, thanks for watching guys and until next time, take care. In 1910, construction workers in Mexico were building an insane asylum atop of what they presumed was an ordinary mountain. Upon digging into the Earth, they almost immediately discovered the ruins of an extremely ancient structure. It was later realized, yet not largely shared with the world, that the hill is actually what is now classified as the largest pyramid on Earth. Hiding under the grass, trees and many tons of Earth sits the once lost and now found Great Pyramid of Cholula. With a base four times the size of the Great Pyramid of Giza, just how did this amazing monument get lost to time? Also, why is it more heard regarding this enormous structure within modern academia? It sits just outside Puebla, the fourth largest city in modern day Mexico. It is 450 meters wide and 66 meters tall, with a floor area comparable in size to nine Olympic-sized swimming pools. Not only is this structure the largest pyramid on Earth, but it is also officially and undeniably deemed the largest monument ever built on our planet. In 1519, Hernán Cortés, a Spanish invader, had his men march into the great Aztec city of Cholulu. They subsequently massacred 10% of the population and built a tiny church on top of the hill as a symbol of their conquest. The church they built is now known as the oldest continuously occupied building in North America. Historical records suggest that when Cortés arrived in Cholula, the pyramid was many thousands of years old and already entirely overgrown by vegetation. Additional legends state that the Great Pyramid was so sacred to the Cholula people that they covered it with soil in order to hide it from Cortés' army. We may never know how it became buried under the sediment it now rests beneath. Experts believe the pyramid grew in stages, successive civilizations improving on what had already been built. When an old pathway was removed in 2013 to make access for a drainage system, workers reportedly uncovered at least 63 complete and very ancient skeletons. Some of these remains accompanied by numerous alien-looking skulls absent their skeletons. Ancient myths from the region told of giants building the structure, with the city's inhabitants being of normal size. From the 1930s until today, great efforts had been made to fully excavate the pyramid. Although these excavations rarely gain any media attention, regardless of the pyramid's enormous size and possible importance, over five miles of tunnels have been dug inside the structure, all open to the public if you can get in them, as locals have reportedly reclaimed the pyramid as their own. Even though extensive exploratory research has been undertaken, the age or indeed the possible builders remain an elusive mystery. Just what type of tombs could still be buried beneath the largest officially classified pyramid on Earth? Were alien remains really found amongst the ruins? And if they were, why was the world kept in the dark regarding the results of this testing? Official reports released at a much later date concluded that they were the decapitated skulls of deformed children. This conclusion, however, just raises more questions. We will keep you posted on further information discovered regarding the site. Thanks for watching, guys, and until next time, take care. 1 and 2 were essentially identical experimental communication satellites. Less 1, launched from Cape Canaveral on 11 February 1965, accomplished only a few of its objectives. Apparently because of the misfiring of the ordinate circuitry, the satellite never left circular orbit and ceased transmitting in 1967. Less 2, the twin of Less 1 fared much better. It achieved its planned final orbit on 6 May 1965. However, Less 1, the American satellite, abandoned in 1967 as a piece of space junk has mysteriously began transmitting signals, an amateur radio astronomer in North Cornwall accidentally picked up the signal and after cross-checking with various lists, has identified it as Less 1 built by the Massachusetts Institute of Technology and launched in 1965 and has been drifting out of control ever since, Phil Williams from near view noticed its peculiar signal and suspects it's caused by a tumbling end over end. He believes every 4 seconds the solar panels become shouted by the engine, it gives off a signal, a particularly ghostly sound as the voltage from the solar panels fluctuates, Phil says. It is likely that the on-board batteries have now disintegrated and something has caused the transmitter on 237 MHz, the lead for decades to have been dead and lost to the vast emptiness of space, to mysteriously start up again. Phil says it's remarkable to think that electronics built nearly 50 years ago, 12 years before Voyager 1 and long before microprocessors and integrated circuits is still capable of working in the hostile environs of space. What do you think of the Less's mysterious signal, has it been hijacked by aliens attempting to make contact? Let us know in the comments. Thanks for watching, subscribe for more. Who built the Great Pyramids? How? Why? Questions many have attempted but seemingly fail to answer. Although claimed as tombs, with the different internal chambers within the largest, Khufu, named in representation of this purpose. Interestingly Khufu or Chiops is the only one of the three pyramids with internal chambers, the other smaller two merely have tunnels beneath. An enigmatic box whose lid has long been lost to history lay within this enormous structure, long claimed to have been the sarcophagus of Khufu. However, although suspiciously small, no one seems to be able to explain how they got it into the chamber in the first place. It is as if the pyramid was built around as it doesn't fit through any of the known entranceways. Since the 19th century, when these chambers were first rediscovered, a tremendous amount of research, though it must be noted, always supervised by official Egyptian antiquity academics, nonetheless, remarkable discoveries have at least been partially shared with the world. Most notably, Gontenbrink's door, yet the tomb of Osiris, where this once inaccessible tunnel led, was, once the media was permitted back into the location, found empty, claimed by officials as being found conveniently vacant. A room only discovered thanks to 21st century technology, according to mainstream Egyptologists, was somehow looted. However, there still lay many mysteries within this most intriguing of structures, and we would expect at least one or possibly many more, which no matter how long it takes us to rediscover them, will be too big to hide. For example, although we once thought the tomb Gontenbrink discovered was inaccessible, the chamber at the top of the structure, one of considerable size, estimated at 30 square meters, is so inaccessible. It was only found with technology used to register cosmic rays, a technology usually utilized in high-energy particle physics, capable of tracking particles called muons produced when cosmic rays strike atoms in the upper atmosphere. These incredibly sensitive detectors were first developed for use in particle accelerators, but they have also been used to gaze into the inner bowels of many geological and ancient artificial features. In December 2015, physicist Kunahiro Morishima of Nagoya University, Japan, placed detectors inside the Queen's chamber to detect muons passing through the pyramid, thus any large chamber still hidden within the pyramid would be detected due to a higher register of muons than expected from denser angles. The chamber's discovery was cooperated by two other teams of physicists. All three teams observed a large void in the same location above the grand gallery. It was a big surprise, says Teyubi. We're really excited, he continued. The researchers say it might even be made up of two or more smaller spaces. Teyubi suggests that it could be, quote, a second grand gallery. It is a discovery, which we are finding highly compelling.

Get awesome prints on the Ender 3 v2 using a default printer profile. My name's Jim and this is the Edge of Tech. So if you checked out my last video, you know we're playing with the Creality Ender 3 v2. Since then, I've been doing test prints so I can show you how it's printing. The catch is, I'm using a default printer profile from Prusa Slicer. It's the Ender 3 default profile that comes in Prusa Slicer. All I'm changing is the temps and we're getting some awesome prints. In this video, I'm going to show you five prints that came out great using a default printer profile. Prusa Slicer is free and they threw the Ender 3 profile in there with the last update. Now all that being said, I did have some issues but it is not the slicer's fault. I got some failures and it was due to clogging. And I think it was because the glitter in the PLA I was using was clogging up the nozzle. So I tried twice, it failed twice and I went on to new filament and that's what we're going to be using in this video. I went to the GTEC PLA Chameleon filament. It is really cool, it's kind of like a rainbow roll, they call it chameleon. And it has a really cool shine and a little bit of a sparkle to it. It printed great through the rest of the prints with the exception of one and I'll show you in a minute. So now that I've teased it, let's check out the prints individually and see how I did. If you remember in the first video I printed this micro all-in-one test. It kind of did everything but what I did was I used G-code from over a year ago on my original Ender 3 and I just put the same G-code in the Ender 3 V2 to see what happens. It didn't do too bad. If you remember in the first video there was a little bit of issues on the overhangs here and maybe on the points there. But it wasn't terrible. But it was not sliced specifically for this using that Prusa Slicer printer profile. So what I did today was I opened Prusa Slicer and all I did was change the temps and made sure the fan was on because it's PLA 100% of the time. And I got a really good print. So as you can see the overhangs aren't bad, up to about 60 degrees, they're great. Everything in the back with the bridging and the letters and the circles and the points look spot on compared to the last one. So the next thing I did was a benchy. Now this benchy came out great. I used the classic settings of 0.2 and 10% infill. I did not change the speeds though because I wanted to use the default Prusa Slicer speeds. But if you check out this benchy it is pretty great. Well if you look at the back it looks awesome. If you look at the stack on the top it is round. It is very nice. There's no stringing on this benchy at all. And even the steering wheel inside came out great. This is probably one of my best benches. If you look at the bottom of it it also looks great there. I probably was a little too close to the bed though. So this warlock tower by fate's end was the next thing I printed. And I tell you what this thing came out pretty awesome with the exception of one problem. As you can see I can pull it apart because somewhere in the center something went wrong with this layer. I'm not sure what happened. It did not finish all the claws that should be around here. And the layer was just really bad and really stringy as you can see. I pulled that layer off. I'm probably just going to gloop this together because I don't have another shot in getting this color change to match the top. But the top printed really well. As you can see here this is the top. It printed very good. Almost no stringing except for the very very tip of the top there. And all the way around it looks great. This warlock tower came from the fate's end kickstarter in which Kimball just killed it. I'm talking killed it. And she is making some amazing towers. Because she did so good on the kickstarter these are supposed to be dice towers in the beginning. But she's making a bunch of different variations of each one. In this case it is not a dice tower anymore.  I don't use it for dice so I really like that. But if you're into dice towers there is a dice tower version of this as well. Check out the link in the description below for all the prints I'm showing you today. And it'll direct you where to get them. Overall this tower came out great even though we had some issues in the beginning. I'm a little sad that it broke but I'll glue it together and we'll be okay. The next thing that was printed was this machine box by ClockSpring. This thing is awesome. This box does it all. It prints with no supports. It twists like this to open it. And it actually pops open in a hinge and it prints all in one piece. Matter of fact it prints face down just like this when it's on the bed. You pop it off the bed and everything spins and it locks into place so that door can't open. This box is great. I really love how it turned out. This was actually printed in coax metallic gun metal silver. So it wasn't the G-TEC filament from earlier. But it was printed in the coax gun metal silver. And it came out great. I love the coax filament as I've said in many videos before. But check it out. I think you'll love it. I just love these ClockSpring boxes. They do such an amazing job putting these things together. I believe most of them print with no supports. All of these files can be found on the ClockSpring Patreon page. They are the very first person that I back on Patreon. You get all of the files, even unreleased stuff. It is awesome. He gives it to you all before the public sees it if he releases it. And I tell you what, you get some really cool stuff like this and the one we're going to see next. So this is the last test print I did before this video. And it's called a saloon box also by ClockSpring. I tell you what, this box came out amazing. I love the GTEC Chameleon PLA and I love how it transitioned. As you can see by the inside here, the layers were awesome. The transitions were really cool on how it laid on the box. And if you look at the lid, it's really cool how they're different colors on each side. It just, it ended up really awesome. And this printer has to be dialed in pretty good to print these ClockSpring boxes. This might be one of my favorite ClockSpring boxes. I saw it with Steven the Lightspeed posted a bunch of them on Twitter and that caught my eye when he posted this box. So when I actually joined a couple days ago, I downloaded this box and that's why it's one of these test prints. I love that the spinning mechanism in the top locks the box just like the last one. And I really love how this box came out in that GTEC Chameleon filament. Like I said, check out the links below for all the ClockSpring stuff. I do not have an affiliate with them. They did not pay me or they did not sponsor this video. I just love their stuff.  So I didn't want to make this a really long video. I just wanted to run through five awesome test prints that we did on the Ender 3 V2 with the default PrusaSlicer Ender 3 printer profile. Literally all we changed was the temp settings and the layer heights and everything turned out great. I really love the test prints we did this time. I'm going to keep those coming in the videos coming forward. Once again, all of the test prints and the filament I used will be in the description below, so check that out. But all this tells me is that the Ender 3 V2 is a great choice, especially for beginners because you can grab it, you can put it together. It comes with great options. The mean well power supply, the 32-bit board, the tensioners, the extrusion knob, the tool tray, all the good stuff it comes with. And I tell you what, it is totally worth it. Once you have it, you grab PrusaSlicer which is free and you use that default profile and you're going to get prints just like this. Now I am going to start tweaking my profile and making it better. This is the last video you're going to see that uses the defaults because I do want to make it better. There are some issues like with overhangs and stuff like that. But up until now I've used all defaults and you can do that too. You can get amazing prints just like this one and it doesn't take much. Well, I hope you guys learned something today and as always, keep printing. What's up everybody? I hope you liked the video. Please give me that thumbs up if you did. Hit that subscribe button and don't forget about that little bell if you want to get notified when we go live on Monday nights for hot makes or when a new video comes out. Check out the clock spring boxes. Well, did you see that?


Item SCP-1459 Object Class Safe Special Container Procedures There is to be only one SCP-1459 per office, and five altogether to a level. The sponges can be stored individually, and passed around when needed, or in a cupboard which they are to be returned to when finished. Lost and destroyed sponges are to be sent back or written up, and new ones received. Information concerning SCP-1459's structure, biological code, and how to grow them is to be classified, along with the location of any tank serving as a habitat. These facilities are to be guarded and serviced by maintenance personnel. Description SCP-1459 is a species of sponge, bound into Mediterranean, known to their natives as the X-sponge, because of the large shape resembling a letter X on its front. This SCP was one of the first discovered by the Foundation, and played an integral part in formation of document appearance and the standardization of how reports are presented. The X-sponge, when brushed over a sentence or a piece of writing, will absorb the text, sucking it off the page, and leave a blank spot. In the earlier days, these sponges were indispensable in censoring documents, and getting rid of offending or dangerous information quickly. The personnel would remove the classified intelligence, and then, in its place write, data expunged. When the sponge was then wrung out afterwards, it would emit a thick black eye-corder, the words in liquid form. This substance could be used to ink out parts of the page by smearing it along the surface, leaving a blocked-out line. This too was incorporated into everyday secretarial work. After many years, however, the sponges ████████ sorry, some got on the page, I'm looking at as a righteous report for inspiration. Became scarce, and as our sites expanded, could not as readily be used by all. New methods were designed, or old normals put back into place, and ██████ even the phrase mutated slowly and the data expunged. As many ████████ forgot ██████, it's dripping ██████, it's origin. Samples of the material, Sample 1, Sample 2, Sample 3, Oh crap, it's drying up, I'll be right back. Sample 4 I hope no one misses any of the words I took.


Look at this nigga just got his feet all out look He over there got his feet. He rubbing toes on top of other toes and all that. That's how you was in a cell, bro Why are you worried about me though? I'm just I'm just asking you when you was in a cell with your cell He did you have your Twinkies out and you just was just just letting your Twinkies do whatever Your Twinkies got a mind of the only sitting on the couch right there next to you Something wrong with you having your Twinkies on me man. Why would it be something wrong? That's the cell It's not just my celly cell. It was myself. I'm not bothering nobody so both of y'all Do you get it? How do you get turned on by me having my feet?  Why are you clocking my feet?  No, my feet don't ever see them bitches roaring. They're bitches got a lion roar to Yeah


I just have a question about the empirical, do you use these kind of buffers to try to assess the fact, is it possible that you have some kind of intersection between buffers that you have some kind of contamination between one area and another area? How do you control that? In that moment we don't control on that, but we can check in this point it's important. I'm sorry, can you show us the slide again? Yeah, this one, the first one? Yeah. Yeah. In the left hand, I think there seems to be a bit of an appropriate trend. Yeah. So perhaps we will be nice and check something like the roughest matter for honest differences of appropriate trends, but we get a more green estimation. Oh, okay. Thank you. Yeah. Yes. We know that we have some differences before the policy implementation, but the trend is clearly that there is a shamp after the policy implementation that increases the total number of university students in those localities. But yes, we have to check about these differences before. Can you show your results for completion? Yeah. How do you interpret this decrease? This decrease, first of all, could be a composition effect of students that can enroll at the university in those localities. We are more students. Yeah. And then they complete that. Yes. But then you don't find this for first generation? No, for first generation, no. We have the opposite effect in this case. So what's your story? Yes. At first, the thing that we discussed is that there are worse students that enter at the university when this campus opens, that maybe they don't study if they don't have the campuses near their localities. But maybe the students that they don't have the opportunity to come to the capital to study, and they have lower costs to study, maybe they are. If it's for me that there are like two types of students that gain access to university, right? The first generation ones, where the ones that work good, but they don't have access, and then the extension, they gain access, and then there's another type of students, maybe, they were hindering them, and they didn't have access to the university, because they don't know the capital. And then maybe they moved to other cities to... Yes, they moved, or maybe... Yes, they moved, or they have the campus near their house, their home. Yeah, but this... Maybe they enrolled... For the first generation, most of them, they had access before, right? So the new ones that are gaining access here, they are worse in terms of... Yes, on average, yes. But when we compare, but when we analyze what happened with these first generation students, we observe that is increased. So maybe there are more... I think that there are two different stories. These two guys tell me different things about two different groups that are gaining access. I think it would be interesting to explore who are the people, they are like this group of these other groups, and there are very different results for them. And then maybe if you exploit them, a better idea of what's going on in the labor market, because then your labor market results, they seem very noisy, and you don't see anything there. But maybe if you focus on these different groups, you're going to... Yeah, it's a good idea. Have a clear story. Thank you. I should be worried about this, because you look at total enrollment for high school students, right? Students, they were attending high school in that region. Yeah, that's local. I'm worried that students are sorting in high school, they're moving to those regions in high school. Yeah, so we don't control of that, but it's important to discuss it in the paper. But because the information that we have is the locality where the people do high school. We don't know where the people are born. If you have information about migration for high school, maybe if you tell me old people that you usually don't move for high school, that's fine, but then it would be nice to do that. Okay, great. Thank you. What's the definition of first generation student? Like first generation student is a student that... It's the first time you go through higher education. No, no. It is the one that enrolled at the university, and their parents did not enroll at the university or tertiary educational level. So you have 80% of first generation students enrolled at the university? Yeah, on the maps with the... Yeah, it's a high percentage of first generation students at the university. So the students who enrolled at the university... Yeah. Their parents don't have higher education. They go better than students that... With their completion, yeah. You have 80% of first generation students, right? Yeah. And then you have a positive effect for your probability of graduation. For them, yeah. A negative effect for the general population. But then you have 80% of first generation. So you must have a really negative effect for the other group. Uh-huh. I think so... Yeah, it's the thing we find in the... Okay. Yeah. How are you fostering your second generation? Is that the geographical reason? At the locality level. How many localities? 140 localities. Thank you. Yeah. So it would be nice to have a normative statement on whether on average it's better off for everyone to have... So if whether... Like having students that enroll and do not complete whether that crowds out resources for other students... If it was more selective, maybe there would be higher quality education for fewer students. That's one thing. And the other one is the graph on your employment outcomes. Is it conditional on finishing high school? No. It's not conditional. It's for the average population between 21 years old and 40 years old. And on the labor market outcomes, we use the national household service. On the other outcomes, we use the administrative data. So there is a big difference between the sample we use here. High school. We can do it. We didn't do it. Thank you very much. Thank you. I don't remember about the program. Is there like a specific year that you can apply? Like just like finish the course or you can apply in the first year of the college? You need to have at least 20% of the courses. And no more than 80%. Because my doubt is like there's kind of worst selection. Like the worst students that they don't have like a job, an internship. For example, they have like an opportunity to cost lower. And they decide, I'm trying to do this, to apply to this program because I don't have an internship here. So I go there. It's kind of hope to have a better position in the job market when I come back. And the guys that are the best students, they are ready to have an internship. But I'm not losing my money. My internship here was you to do this kind of a job. Yeah, it's a really strong assumption, right? That's what I'm making. Like really strong because remember that those are students from federal universities. So they are on average better than the average students in Brazil. So yeah, I think it's a very strong assumption. I'm not sure if this... The comment that is supposed to be on this paper, take this opportunity. I think it's a very good job, as well as a good paper. Part of the effect, and also the effort of some of the makers while you are visiting Brazil. Part is, of course, a bit specific. Maybe if your channel is correct because it was Amanda Akimakura. Yeah, perhaps I was wrong. But the comment I'm going to make more generally is that I can't get this discussion with Shibiko. Sometimes in economics, we tend to be very precise about sort of small analytical exercises. And then we have difficulty interacting with the bigger questions. So for a second, if I try to put your results in a bigger perspective, I'm going to think of an effort that Nora Eusti coordinates and the commitment to everything, et cetera. This is a problem. The impact evaluation gives us negative, which is horrible. You spend a lot of money. And if I do the distributed analysis, probably this goes to middle class, for upper middle class kids. And they say that if you go to Shail, the channel gets shot. According to more general method on how you allocate public money and public effort. Am I too far from reality? No, no, no. You are completely the reality with your analysis. There is a big debate in Brazil about this program. And there are a lot of evidence also that many students did not study at all. Because there was no rule to the minimum number of courses you need to do. There was no requirement of quality. For example, you need to enroll and also get approved in some courses. And as I mentioned, you are basically giving a lot of money to young people to go to Europe. So if you take, for example, one scholarship that is 1,200 euros to go to Portugal, is two times the minimum salary in Portugal. And maybe the student is more than the per capita income in their household. So yeah, there are a lot of discussion on how the program was created. And yeah, and how was the monitoring of the program and the rules, etc. Yeah, one thing that we cannot observe here is that many students can could increase the cultural capital, the networks. They could influence peers, for example, if they had a brother or sister that saw him going abroad. And so I also want to have an international experience when I do my university. So this could be a positive fact, but we cannot observe this here. But yeah, I totally agree with your comments. I think one, following up on this, I think one important thing that is important to clarify is that your IV is measuring the effect on compliers, right? So those are the marginal students that gain access because of the random compatibility. This program might be good for people at the top, right? Yeah. So I think this is really important for you to sell the paper to make a more general contribution. Because it might be the part of... There will be a group of our stakeholders here, the guys that have super-high interest-exempt scores. And they probably are people from rich families and have very good background, for example. These are not the guys that we are capturing here. Yeah. Good things. It's a long story. The first year that was really hard to get into the program. Because you didn't only have to apply, but you needed to have an research program with a professor at your home university. We revealed a few more students going and students that were committed to study abroad. Yes. On the cost of our training, I know that you knew the universities. So you had these universities that you wouldn't really choose from. So I don't know if this changes your results in any way, but it's good to control. And the third thing is, can you maybe do a regression controlling for your graduation and see the results hold? The university didn't provide the year for graduation. I'll follow up on my previous program. I'm trying to compare the whole set of social issues with the country and some sort of decisions of the margin. And that's what you were writing for countries like Argentina, Brazil, and the United States. These countries don't change. And this case would be exactly the opposite of the previous one. Because in the previous positive effect, the amount of money spent in the policies is probably small because this is a regulation. I don't think there is a margin for this, et cetera. And then in the third or the fourth generation. So just my mind will come and do this. Every paper should finish with two lines consisting of additional aspects usually not considered in the previous paper. I'll follow up on this intervention. It seems that was right. Yeah. Thank you. Yeah. When you have such a controversial policy as a very large affirmative action policy as this one, it's really important to put in a larger picture and have very, I think, convincing rigorous evidence on where it works and where it does not. There are some aspects of this policy that I have worked on that too. Some aspects in the design that can be improved. And we also talk about that. But the overall picture is that this policy has been very successful in decreasing inequality in access to universities. Yeah. Chico. No. The problem is that Prova Brasil for high school concluders was not sensitive until 2017. So, yeah, we have a small sample problem there. We try to use a name. But then there is, it's not ideal either because there is a large difference in take up. So then composition gets really mixed up. So every time we try to do something with the college, with grades, we don't get a clean effect. That is not mixed up with composition, things like that. But, yeah, we are trying to get a sample for which we can do this. But, yeah, we haven't been super successful so far. My other paper. Yeah, I have another paper that shows that people move from private to public schools in response to this policy. So in this time period, that's why also we stop in 2015. Because for this time, yeah, they need three, they have to be in high school for three years. So, yeah, in my sample, there is, yeah, no endogenous starting to high school. But, yeah. I'm not sure it is relevant because there are some sites but maybe also the creation of new companies. So, for example, we can have a university in one state and a university with more countries in different cities. So I don't know how this would affect the college. Yeah, so this expansion of college seats is, I mean, the idea is that the policies are not correlated, right? They are orthogonal to each other. We can't control for this. So we can observe an opening of a campus or the number of seats. We have control for this in one of the specific issues but it doesn't change anything. The idea is that, yeah. And do you know in which states or regions the effect is stronger? For example, if you drop out the data, like you have a high impact, they somehow know that the guys have this communication or clear their name as Mao Zedong or states of North-East that the guys probably have more difficult to know that they have this kind of change in the situation. I know that the larger expansion is actually in the Northeast. So like the South already had quotas, but like the Northeast, I don't know if the effect comes from, but like the large, yeah. The national law affected more universities of the Northeast, but yeah, this is a good point, yeah. Let me see if I have time. Yeah, so I will take the questions and then I answer, yeah. Can't you just compare places where you have good private colleges and then you have an outside option that is good and places that you don't have a good private college? So if the percentage of people not taking the name in those four countries is different, it's indicative that people are just going to private colleges, right? And are you just seeing if they take the name in the year they graduate? Yeah. Can't you just see if they take the name? Because the person that came to my mind, it is the name, like if they can get here or something. So maybe just say, no, maybe this back, yeah, maybe that back when he has it described to me. I'm going to take the questions and then come back, yeah. I don't know if that's correct, but around the same time, it's really popular to stand in the same way that it increases supply of private colleges. So I don't know if the displays need to be private, what would happen because of a crowd out of, you know, actually not a crowd out, but get more supply of private universities. I'll see you in a little bit of time. Yeah. Yeah. 2012. It should be, let's say, control your... Nice specification. Yeah. There was any other question here? Yes. And you mentioned that you were estimating, realizing how for all of the trends assumption, I'm not entirely sure what it's appropriate for your attitude. To whom are we expecting these for all of the trends? Could you clarify that for me? Yeah. Okay. So first, regarding the displacement of private colleges, and I think this is a good idea, Le, to do this heterogeneity, whether they're a good substitute in the private system. So the problem is that to do that, we need the data, the restricted data from SADAPI, so we are still entering with the project there because then we really need to connect individuals and follow them later on. So, yeah, we are doing this, I don't know if it takes time, but I think, I mean, if we want to take this project to the next level, we are going to, yeah, we are going to do that. We are doing that. It's just that, yeah, it gets a lot complicated when you leave the public data and go to the restricted data. Regarding Renata's question about the increasing supply of private universities, I think the answer is similar to my answer to Rodrigo. Rodrigo asks about the supply of public universities because there was a reunion, which was the big program of expansion. And my answer to that is that, I mean, I think this matters for human capital accumulation, but for this to bias my estimates, they would need to be correlated to the exact pattern of adoption of affirmative action. I mean, I think I have to show you, I don't think this would be a problem. I haven't controlled yet for, like, supply of private seats. I think I should do that, yeah. I controlled? Yeah, yeah. Yeah, there were, yeah. We, what we do is we control for, there are a lot of policies for public colleges, like Fies, Reuni, all those things that we try to account for, but yeah, there's also the private universities that, yeah, high education is a fascinating shooting in Brazil because there are, like, so many reforms as you saw. You were right. This is important. And my last answer to control versus treatment here. So, like, treated institutions are the one that expand the most, right? The ones that had the lower level of quotas before the policy, and then they were more affected by the national policy. And then in this case, our treated institutions are not institutions, but micro regions, right? Municipalities, re-aggregating institutions, the treatment is at the institutional level. They treated are the ones that were not affected by the national reform, basically because they already had affirmative action policies before, okay? We also have an alternative treatment of state universities that had no quotas before and so on, but this is our, like, we chose this as our main, yeah. So, yeah, I conclude here. Thank you.


Day by day we are working our way through the workbook lessons of a course in Miracles and Today we are on another review lesson. It's review lesson 59 we're reviewing workbook lessons 41 through 45 So welcome happy to have you along on on this journey on this ride So let's check it out here the following ideas are for review today God goes with me wherever I go How can I be alone when God always goes with me? How can I be doubtful and unsure of myself when perfect certainty? abides in him How can I be disturbed by anything when he rests in me in absolute peace? How can I suffer when love and joy surround me through him? Let me not cherish illusions about myself. I am perfect because God goes with me wherever I go God is my strength Vision is his gift Let me not look to my own eyes to see today Let me be willing to exchange my pitiful illusion of seeing For the vision that is given by God Christ's vision is his gift and he has given it to me Let me call upon this gift today so that this day may help me to understand eternity God is my source. I Cannot see apart from him. I can see what God wants me to see. I Cannot see anything else Beyond his will lie only illusions It is these I choose when I think I can see apart from him It is these I choose when I try to see through the body's eyes Yet the vision of Christ has been given me to replace them It is through this vision that I choose to see God is the light in which I see. I Cannot see in darkness. God is the only light Therefore if I am to see it must be through him I have tried to define what seeing is and I have been wrong Now it has given me to understand that God is the light in which I see Let me welcome vision and the happy world. It will show me God is the mind with which I think I Have no thoughts. I do not share with God. I Have no thoughts apart from him because I have no mind apart from his As part of his mind my thoughts are his and his thoughts are mine Those are our thoughts for review today.  I cannot see apart from him God is the light in which I see God is the mind with which I think Beautiful and for support for some boost of support from the from the texts I Just you notice that all of those ideas have one central theme God So I just typed in God in my Course in Miracles search program And I thought this is going to be good for support and what came up when I typed it into my Course in Miracles support Engine here it basically came up with four thousand four hundred and forty four Mentions of God, so I thought I would sprinkle them through and Share some of those with you. This is as great of support. I think for for these Review lessons as we could have all Miracles mean life and God is the giver of life Miracles make minds one in God Through miracles you accept God's forgiveness by extending it to others a Miracle is a universal blessing from God through me to all my brothers Miracles praise God through you You should thank God for what you really are The children of God are holy and the miracle honors their holiness which can be hidden but never lost Miracles are examples of right thinking Aligning your perceptions with truth as God created it When you return to your original form of communication with God By direct revelation the need for miracles is over Revelation unites you directly with God. I Have nothing that does not come from God in the process of Rising up. I am higher because without me the distance between God and man would be too great for you to encompass And that's that sense of I am higher that's Jesus I Am higher Jesus is higher because without Jesus the distance between God and man would be too great for you to encompass Again from Jesus I bridge the distance as an elder brother to you on the one hand and as a son of God on the other the Holy Spirit Mediates higher to lower communication keeping the direct channel from God to you open for revelation The ability is the potential the achievement is its expression and the atonement Which is the natural profession of the children of God is the purpose You are the work of God and his work is holy lovable and holy living Miracles are the way in which minds that serve the Holy Spirit unite with me for the salvation or release of all of God's creations When the atonement has been completed all talents will be shared by all the sons of God Ultimately every member of the family of God must return a Sense of separation from God is the only lack you really need correct All real pleasure comes from doing God's will Do not deceive yourself into believing that you can relate in peace to God or to your brothers with anything External child of God you were created to create the good the beautiful and the holy Healing is of God in the end In the creation God extended himself to his creations and imbued them with the same Loving will to create Everything God created is like him Wow So you feel the wind underneath our wings today It's God So One more time we'll just go through these review lessons and then launch on Into the day Singing a happy tune with a sparkle in our eyes with a smile on our face with a happy step in our walk God goes with me wherever I go God is my strength vision is his gift God is my source. I cannot see apart from him God is the light in which I see God is the mind with which I think Beautiful day launch launch launch here we go Shine share extends sparkle Amen to that


when the Holy Spirit touches you something shifts inside and you know at that moment something happened nothing might happen on the outside but the Word of God got planted inside you might say well this is the Word of God you know that's not enough and my faith is not enough I need to see the change we must understand that faith is another sense and that sense is as verifiable as every other sense you have in your body for example we have five senses in our body through which we perceive something to be real your eyes tell you what you see your smell tells you what you smell now for example if I spray perfume right now around you you won't see perfume but your smell one sense out of five will send you a signal saying there is something in the air and it smells good your eyes will say I can't see it your smells are shut up you're not supposed to see everything we can't trust you only with everything God also gave me a portion to control and if I can smell it you don't have to see it see and then there comes another sense but many times God added sixth sense and the sixth sense is faith and many times we butcher faith bully faith because the eye said I can't see it the smell says I can't smell it the hands say I can't touch it and handle it and faith has become ridiculed faith is for the foolish for the fanatics and for the ignorant really why do you don't treat your smell like that why is the faith is trampled under the feet of five senses when God raised the faith to be on the same level as all the rest of five senses we have to give faith the same honor you give to smell when faith says it's gonna happen the smell has to sit down and learn when faith says God is gonna heal your body the eyes have to shut up and pay attention when faith says God is gonna bless you and prosper you the ears have to close up and say we trust you the way you trust us when somebody says something see I speak words you can't see my words but you're trusting one sense in your body it's your ears only one the rest of the senses right now are silent the information that is coming into your mind is coming only through one sense and this sense is exalted above all other senses and the rest of the senses are bowing and saying yes yes whatever you say because God didn't put all of the authority in one sense the eyes that's one of the reasons why our faith has to be developed this sixth sense if God has said in your spirit if God has said in his promise listen the eyes the ears the smell the touch and everything take a seat relax that is outside of your pay grade so shut up and pay attention to what the sixth sense the faith says

You hardly sleep, alone, night after night, you sit by your computer, looking for the truth. But you have been given an illusion of choice, a substitute of what is real. Because when you are confused, you cannot resist. And when you cannot resist, every aspect of your life will be in their control. Our leaders have failed us, the medical system has failed us, our freedoms are being stripped away, our planet is being destroyed, a 2000-year-old prophecy is coming true, a time of wars, floods, disasters, disease is now at hand. What will you do? Welcome to the era of quantum energy. It's what scientists at NASA and Tesla have been searching for decades, a technology that allows you to choose your reality, a technology that empowers every citizen on earth, a new future of preventative healthcare, a limitless energy source that can restore the planet and create wellness and abundance for every living person. This energy has always existed, now you can harness this power with our technology. It's time to stand together, stand united for truth, protect our loved ones, give hope in place of despair, offer freedom from control, we define a world of suffering and misery. Imagine a future where scarcity would only be a concept of the past, while working together with artificial intelligence to cure aging and end disease forever. This future is closer than we think. After 20 years in the making, backed by evidence-based research, we are now embarking on a new journey into the frontier of quantum energy medicine. If you are looking for an answer, it will find you.  Join the quantum energy movement and unlock your human potential. Listen, feel, feel the energy, quantumenergy.ai.


All right, folks, hey, welcome on back here. This Monday afternoon, great to see all of our students and members alike inside our live trading room. Let me pop the webcam up at least from there. Great to see Dominic, great to see Marguerite, Kathleen, or Rijan, great to see Brad, Andrea. Grant, Leda, all of our students, rejoining us perhaps, great to see you. Let me just get a quick sound check to begin. If you wanna hear me loud and clear, hopefully. There we go. Dominic, Lawrence, Leda, loud and clear from everybody. Good morning, good afternoon, good evening, or you may reside, but without further ado, let's hop right into the thicket thing so you have this CXAI trade. Nice little push up for the beginning here. I mean, across the morning it ended up beginning, but now at this stage, it's holding closer to the highs.  So the closing bell print from that price that day, $6.15, $6.15, so it hasn't really made a clean breakout just yet. That's because it's probably just chopping up. Maybe there's a new resistance level right above it, maybe a new sell order popping up in between, or otherwise maybe we'll see a new buyer step in to help with that push, but yeah, we'll put this on our watch list. Actually, let me just show you the level four here while I'm at it. So, yeah, I mean, it's not too far away, but at $6.50, about $58, $59,000 shares roughly sitting there, so we'll definitely put this on our watch list to begin. It's treated us very well for the last month or so last couple of weeks at that, and we'll see if this could look to continue, not even back from the beginning of this month, really back from beginning of March, really, end of February even. So, hey, let me ask all of our students here in chat, Charles, Kathleen, et cetera, what other AI stocks do we tend to focus on? What other AI stocks are there out there? I'll give you one right now, AI, C3 AI. That's not really moving though, right? Not really budging. So what other stocks are AI affiliated that we've been trading over the last week? What do you have for me? Work together as a team, we'll build up a nice little list, right? So what do we got? Any of our students here? Dominic on SOXL, maybe, but that's more like the chip semiconductor-based ETF. That's more like NVIDIA, AMD, et cetera. Lata with MDAI, Sam from up top saying SOUN. Yeah, we'll take a look at those. MDAI, not really going anywhere. Got one in between, BBAI. Not really budging too much, but the SOUN. I was gonna just kind of spin towards this year anyway. So SOUN just earlier today, I was hypothesizing. I wonder if this could look to make a runoff of $5 at like $12.53, I wrote that to you there, popping up on the top right. Also actually, I'll show this on the heat map too, but I wrote to you as well afterwards. SOUN had a one million share, one million share iceberg order on the buy side at 480. I know Grant was looking at it then. I was making a joke at the time just earlier saying it's like that meme SOUN. It ain't much, but it's honest work. Now it's pushed up a little bit more since. So yeah, I'm gonna put this on our watch list here too. It's just one that we're familiar with. It's making at least a slightly better push alongside the CXAI. Obviously CXAI is the better of the two, but yeah, here's your one million share buy order out there. It's on the EDGX ECN. If you're on the old fashioned NASDAQ, but fewer it's gonna be hard for you to find that. It's just not showing there. It's through a different ECN, but I'll put CXAI, I'll put SOUN both on our watch list here to begin. See if both can keep trucking up. Now what we will do though is just go right from top to bottom otherwise, oh actually maybe one more AI stock while we're at it. I haven't checked in with this trade really since the early morning actually. Very, V-E-R-I up 9% up even more than my SOUN. So yeah, this one's pushing right back on up towards where we topped off back from Thursday last week. You have that 11, 12,000 shares on the sell side here at 724. I don't have the heat map, at least up just yet, but you know what, CXAI vary. And then the SOUN kind of in that order I'll go with. Even though I'm in SOUN, it's the third one there. I think CXAI and Verrier, the two better looking at the trades. Sam said used to do bullfrog, but it's going nowhere. There we go, answered that, right? Now maybe there was another AI-based company or whatever the hell maybe just on the gainer side here, but let's just go right from top to bottom right now see what else we can grab here. Yeah, AUUD, I think that this one's done with for right now. I could actually just kind of expand my gainers list here. Take a look at the float or maybe you could just even say lack thereof. A two million share float, that's tiny, that's microscopic for what we normally even trade. So look at that, look at ETAO that is, I got to get better eyes. UCAR, that's even, I don't know what's going on with that trade. Those low float stocks, it's already testing support over and over and over. So you know what, I'll come back to AUUD is more of like an education thing and an example thing here because I think it's going to break low. Wait, see if this can make a better push coming up. It's like just kind of teeter tottering here already made a better push earlier this morning or earlier this afternoon, mind you, one o'clock, that is one o'clock to 1.30, 1.45 pretty much ended up making that run but from there hold back, I'll come back to it if I need to but I want something that's sticking better to the highs like that CXAI trade, the very, something of that line, something of that nature. Yeah, this seems a mess. What is this, a 20,000 share float? I don't think that's true. I think that's got to be like a glitch or typo from trade station. But we keep going through though. I mean, for a Monday, right? You typically expect nickels and dimes, nickels and dimes but we did really well today on a few different stocks. Some of the pot stocks as well, CGC, ACB earlier today. ALCC, you gotta respect the chart. That is a beauty of a chart, higher lows, higher highs across the afternoon just kind of a skimpy book, not really to jumpy towards something like that. Say the same thing here on STI, it's also kind of near the highs but OM, can you get a lot that looks like that? Not, hopefully not a lot that looks like this, this is a buyout. Just kind of keep going from there. You got Coinbase ETF up there, LifeW, that was also really, this was actually, it doesn't look too good but this was a really great trade from earlier today. We got out just in the nick of time, so it called us out and head on pretty much. Topped off a little bit earlier than that, presumed to 10, 15, 10, 30 reversal hour. IRBT, that's right, this one. All right, so remember actually last week, if you folks were here with me last week, we were talking about, what was it, Apple or Google, one of the two, with the partnership, we were trying to make the at-home robots and that'll go over really well. Well, when that news came out, it was with iRobot, IRBT, I believe, this company here. Had a big pop and drop back, I think on Wednesday it was last week and then now it's actually gradually pushed up higher. Got resistance up top here at 10. It's not a bad one to just throw on our list for now. Kind of put it towards the bottom here for the meantime, but it's a decent look, got a decent order book, resistance at that whole number level at 10. S-O-U-N, still trucking up right now, penny by penny. It ain't much, but it's honest work, as we said earlier. All right, we keep going through. You got Tesla ETF here, TSLL. There's our very trade. Let's take a look at that Tesla ETF, why not? You know, it's at the highs, don't get me wrong. Let's just take a look here. Just obviously pretty similar chart, TSLA. I could add it at the end of our list. You know, it'll come back to Tesla and the ETF there, TSLL. All right, let's hop over to the loser's side here. Actually, before I do, take a look at the SPI, just seeing how the markets are looking overall. So Tesla definitely doing pretty good for today, given SPI hasn't gone anywhere. In fact, right now, a bit of lower highs from the morning, so maybe a little bit of a pullback heading into the afternoon. We were focused on a big level on the SPI last week that we'll still look at. I think that was like 517.50, we just had up. PERI, P-E-R-I, where is it, PERI-ILS? Let's see. Carry on, network. Don't know the company, don't care as much, and that's not just me being ignorant or whatever, it's true because we care a lot more about the trend, we care a lot more about the liquidity or maybe lack thereof at times. This does have some pretty good liquidity. And the fact that it actually is easy to borrow from you on trade station, you always get asked like, hey, do you short stocks? Of course we did. I know, what do you think happened during the pandemic? Ended up, I mean, at the time, that was before I was buying options then, so I wasn't even doing puts. So it's just a matter of just trying to short stocks that weren't easy to borrow, maybe even during those times, follow an inverse ETF, but nevertheless here, PERI, just on its own, whatever news came out led to a big move for anyone that's a little cautious and I don't know if they're curious minds, I'll take a quick look. I was looking at some of the pot stocks earlier to see what news was out across that sector. Let's see. Quarter one preliminary financial results, gotta be lower guidance, right? After they slashed fiscal year 24 guidance and issued outlook below estimates, so that's typically the headline when it's like earning space like that, that are like the whole board quits, but end up leading to a pretty good drop off earlier today and still at the lows. So I'll add that PERI just as a short. Let me know folks, just, oh, that's right, JTAI from Kathleen and Chow. I'll take a look at that too. Just didn't see that up until right now. So if there's anything else looking good, just now is your chance folks, up down left, right, more than 5%, just let me know here in chat, around a mile and a half midday today, drinking my water infused with creatine and Himalayan salt. Pretty good hydration, but otherwise, let's see if there's anything else here to wrap up. That's not good. JTAI, it's one that, it is an AI stock, it is an AI stock, we're definitely not one that we will want to follow. So, I'm gonna just go back to my side list if I need to, like I said, a couple that we'll just check out here at the end, AUUD, still nipping at that four level. I feel like it's just gonna crash it here momentarily. ACB isn't really going anywhere right now. CGC, I took a small trade on this, just as it was trying to make the break above 1022 level, 1025 just before. So that could still be in play, but I'm not gonna put it on our main list. It's volatile enough where if, stars align, we'll call it out, but if not, we got better trades to work with so far. I guess with that, I will add, even this is pulling back now, right? I was gonna say Tesla and the ETF there, but not a great need for right now to put that on our list. So I'll tell you, not a big one, we got a few different AI companies out there, the CXAI, the SOUN, the Vary, we're off to a good start on SOUN at least already here. That didn't need that to rhyme. IRBT, PERI, Dominic asking about the DJT trade. Is it short? Because that would be a bad looking short, just hard to borrow an otherwise order book thin. So this is where I say all the time, and I just say this across the board to every person here. For stocks that are very thinly traded, you gotta have a very good reason to trade it, right? I'm more keen to following a stock up than down. I feel like that's all of us. Yes, we do short, I just said it earlier with PERI, but you know, DJT with Trump, like on Haydn, light, right, left, down the, whatever, just focus on tradable, focus on tight spread, consistently filled in order book. This stock never has that. So unless if there is an extremely good reason to follow the stock from me, you know, maybe the cheaper it gets, it'll fill in more of the order book and it can be a better trade. Actually, the order book looks even slightly, even like, I guess, a tiny bit better compared to when it was like a 45, 55, $60 stock, back last week. So, you know, I just don't wanna catch a falling knife. I'm not too interested in this trade for right now, but maybe if the order book fills in more, maybe if the company does a stock split, I doubt that will happen. I'm just saying, or if they do like a common stock offering, maybe the liquidity can fill in better on the order book, but that's all. Sam says, if the stock is hard to borrow, can buy puts, true, but I, you know, for anyone that's not really too confident with their trading, I wouldn't want them to be switching over to options just out of nowhere, especially for anyone here. Like if you got, if you're an active day trader here, that's one thing, but I wouldn't want anyone to be trading options when they shouldn't be. And again, we got better stocks to work with. So, you know, folks said, let me know. Last call here, going into the close. I'll be back on the mic in about 15 to 20 or so minutes at 3.05 the latest. I'll be back on there.  So be a friend, tell a friend, just make sure to hit the follow or subscribe button if you're on YouTube, that being at cyber trading you. Again, at cyber trading, you popping up on the lower left, on the top left, you should see a little QR code. If you're good with your phone, good with your camera, just scan that right there. Take you to a quick landing page, get you signed up for a week long trial inside our trading room. That's normally where we have all of our education, all of our chat throughout the day and our students and instructors, of course, Fausto, 35 plus year pro in the market myself. I've been doing this for nearly 10 years. My college rich nearly five years at this point. So we are scanning all throughout the day and for our students, well, it pays to be a member, it pays to be inside the chat board. Even if you're not actively trading, it pays to be there because you can never stop learning as far as why we're doing what we're doing. But hey, for all of us there right now, I'll be back on in just about 20 or so minutes. We'll go from there folks, trying to find one more runner here, one or two more runners here heading into the market close.


Thank you for coming So welcome. My name is Davide and I work for Red Hat in the networking services team Today we are going to see how we are extending packet drill The goal is to do unit testing and sanity testing for the MPTCP protocol Yes, there has been already an MPTCP talk yesterday made by Paolo where he displayed all the All the efforts in doing the upstreaming process and it was kind of successful because we saw that And that's a very nice thing today we are going to cover up some use cases and How it looks like from the user perspective and of course we will see how we can test the MPTCP So and that's what we are going to do a quick overview of the MPTCP status and Some inner workings of packet drills and then if we will have time We will see if you have any questions and answers and they are there can be for them. So Don't be shy so Are we talking about something really new not because the MPTCP specification? published since many years and Moreover, there is an out-of-tree module that can be built and You can already use MPTCP on your computer and If you have some Android devices also, you can use MPTCP and of course, there's iOS uses it natively What is new here is the protocol version which is a Very new the RFC has been published a few weeks ago so there is version one and it's an IETF standard and What's new is of course the official implementation for the Linux kernel, which is going to be merged gradually in the next weeks Then what will become the next development will be the user space part manager, which will handle the control plane Maybe something to do the flow scheduling in the correct way Yes, I put some References on the bottom of my slides So in case you want just download the presentation and have a look at the sources so this is an open source project and It wouldn't happen without a community. So first of all I have really to thank the MPTCP open source community and I Would like also to thank you if you are willing to contribute to any of these tools and to the Linux kernel and of course to pack a Okay, so Yesterday, there was the question was the use case for MPTCP There's this there is this nice diagram from the IETF Slides back in 2000 and 12 I guess and this is the typical use case for MPTCP So you have a smart phone client There is a web server and you can make use of both the mobile connection and the Wi-Fi connection together To have a somehow better experience. So It's the typical use case What Wi-Fi mode to mobile and over? So in this case when you have two different path to reach your server You can improve your experience if your socket can survive after failure and Maybe you can also have a better experience if socket can aggregate the capacity of different links in order to achieve a better throughput It's not like So it's like a l4 bonding. It's not like New thing. There are other different solutions to the same problem As CTP is one of them and multi path quick is another and Well, now we have three Okay, so how do we Use MPTCP for real that sees typically From the program as point of view what you have to do to use the MPTCP protocol The stack registers to the kernel using as a protocol for IPv4 and IPv6 so You have to call socket using the new IP Proto MPTCP Which has be extended to 16 bits in order to cope with the this new value Then After the socket is created there you can operate the socket like it was a regular TCP socket and This is the example for what happens to a server so you just Bind the to the address listen and then when an incoming connection Connection is detected by the kernel you accept the connection and then you can read and write bytes from the socket This example is taken from the case of test. So we already have case of test in the Netnext kernel tree if you want to see an example of client and server, please check out the sources. Oh by the way MPTCP socket can also be monitored like regular TCP socket. So Once socket is created then the stock will create regular TCP socket To carry the traffic and this is done using the TCP ULP infrastructure When a ULP creates a TCP socket, you can just monitor it using SS command and What you will find here is The ULP Relative Information At the moment you will only see this thread but the message already contains some more stuff That can be used to troubleshoot your connection. Moreover, we are going to implement the support for innet the other and With that it will be possible to know which process sees are opening MPTCP socket. So once MPTCP starts transmitting packets you can use TCP dump to Sniff the packets and you will see MPTCP related information in the TCP dump output There's also wireshark support and this is an example of 3-way yam shake Where the MPTCP client and server exchange their keys This is an example of MPTCP v0, but soon TCP dump Will accept the pull request that implements support for MPTCP v1. So it's code is already there Okay So now that we know how packet MPTCP can Be operated and how packets are there. We can just use this information to do some basic testing Why we are doing this because of sanity because we are Touching the TCP protocol and we need to ensure that TCP will be the bug free even after our our modification and also to test the MPTCP protocol and assess the Correct implementations versus the IATF standard. So let's see how packet drill is and how it works So a packet drill has been developed by Google To do unit tests for the TCP protocol as you probably know the TCP protocol has many extensions Many options that are obtained that are optionals and there is a test suite for that So it provides a coverage for most Probably all the TCP features and for the socket API with packet drill There is already out of three part of the project that is meant to do the unit testing for the out-of-three module We cannot use that tree at all for the MPTCP net next because the socket API is different and Moreover, that one does not support v1 yet probably will not support V1 at all because we are trying to make this Working for both versions out of tree and in tree Okay now How packet drill works? so So this is a typical command line that I do in order to run a script packet tree is made with a A program that passes a script the program uses a packet socket to inject packets and to sniff packets from the kernel that we are testing and There's the possibility within the same scripts to send system calls So you can open a socket you can listen you can find you cannot check you can read write you can to pull everything can be done in the same script and This is a typically what happens the script does the passing then packet will read the line and Determines whether to send any bound packets the terminologies that inbound packets are packets directly directed to the camera Or just receive an open packets So from the kernel to packet ring and this is done with a dissection so it can understand whether the packet is correct And then of course we packet which you can send system calls to the kernel under test Now this is an example with the TCP protocol It's not a real test done by the TCP I just Be able to explain this so It's a server Transes a server we open a socket bind and listen and then on This packet we send a sim packet and start the trip we ensure so the camera is a server and packet drill acts as a client Once the connection is accepted. I try to forge a bad packet. It's this purple one. This is a bad packet why anybody knows it's a bad packet because It does not act anything So it has no flags It does not act and the standard says that this is a bad packet and we should discard the details from this how do I test this by Checking how many packets are in the socket queue? if the expected back there Packets in the queue are there. This is the expected there and the test goes on Now I send the same packet With the good flex, so I And it acts Exactly the data that have been received now. I repeat the same To check So this is a correct way and now I can read this 1000 bytes and The test passes Yes, it passes Okay So what we do now with mptcp I Took the out-of-tree code and re-based over the latest drop from Google and I did some modification to have it dealing with the mptcp socket with the new number and after that We have the support for the version one of the protocol and Started adding some tests. We have the test for the mp capable option We are the test for the DSS and basic support for the DSS, which is the data plane So by the way, this one is the repository where you can download the latest packet here is Something similar to the test you watch it before but it's related to the free way and shake of an mptcp socket So as you can see there is a server on the first four lines and There is a three-way and shake but now we can see that we are dissecting and Injecting mptcp option in the mp capable So also in this case I have to put a bad packet and The very first test was to try to inject a packet with the wrong mptcp version Here the standard mandates that we should fall back to tcp, so not resetting the connection But fall back to tcp and not talk mptcp anymore for this socket So I still checked the connection and I check if the data plane is functional So I'm able to write and read bytes from this socket But I will not transmit nor receive any DSS option Okay the DSS option so The DSS option as you probably know Controlls the traffic plane, so it controls the mapping of data between the tcp level and the mptcp level doing a test we want to control if the data sequence signaling is correct and so This is an example of testing the DSS option after the three-way yank shake we do a write and We expect a packet having the DSS option that acts And then we do a read and check if the Data arc increases by the number of data that we read So in this case the mptcp specification allows different formats for the DSS adder, so There are many options you can use DSN and the DAC values made of 32 or 64 bits In any combination, so it's very very likely to find bugs here Okay now What about mpt join because mptcp is multi-bots And we want to test multi-bots Amounts the mptcp option mp join can be used to join an existing connection So once an mptcp socket is open You can create another flow and you will see the mpt join option in the packet well This is done in the out-of-tree module using a sort of hint, which is this green work that you see there um So and the out-of-tree module tends to open a different socket from user space for each subflow and Then join them them together So typically the out-of-tree module Wants to send An heat to the passer saying okay this packet is Destinated to socket number five. Of course this cannot be done in the Netnext mptcp implementation because since we are using the tcp ULP Sockets are handled by the kernel and the user will only hold the mptcp socket handle so This one cannot be part of the netnext implementation We are implementing a way to Allow testing multiple sockets simultaneously that would improve also the capability of testing tcp and Of course it will allow to test the mpt join Next to come what we'll be next we will be Implement the join scenarios Like I said before and then we will implement what is missing from the code to the spec So we are we'll be testing the other option MP reset option also the ladder and of course once we add a new option We will increase the test coverage we expect the test coverage to be very very big and Like I said before any contribution is very welcome So if you find out some tests that can fit Packet referendity simply please do a poor request Okay, I think That's all do you have any question one candy one candy. Okay first first first you Okay, so the question is What is the state of mptcp protocol versus IPv6 connectivity? Yes, so the out of three modular resist registers It sells as a protocol bought for a finite and a finite six so It's meant to work with the IPv6 IPv6 protocol since the very beginning This applies to v0 and v1 But probably you will only see v1 if you test an official new cabinet because Implementation is starting from v1 protocol By the way, if you run packet drill, it's possible to see to test with the same script IPv4 IPv6 and IPv6 map up to 4 so there is a good script that tested all Other question Okay, so the question is do you plan to enhance IPerf or IPerf3 or netperf maybe also to add support for mptcp theoretically Yes, that would be an option. So it Would just be a poor request in order to support the new IP protocol version on the socket and that's it, but Our plan is also to have this Supported in a seamless way. So using a BPF program you can overload the socket method Catching the new IP protocol and ptcp value. So once you see 262 in the IP protocol the BPF program changes it to b6 and so using the same API you use a tcp program, but for real the kernel is doing mptcp So that's it. That is what we are thinking about The idea is to make a BPF program on top of our C group On top of our C group B2 Sorry don't get the question You can send us a thousand back and so as soon as you do a right In a pocket to a script If the if you are writing enough bytes then the kernel will send many many bytes and It's supposed GSO so and TSO. So if you send a big amount of the data and the kernel as TSO on you will see a mega packet there You can turn off TSO Send a big amount of data and we will have to dissect As many packets as They fit to the size that you sent Sorry, you have to take hands, but otherwise the questions are not good Okay, so the question is what about Scapi because Scapi can do the same thing as packet drill Yes, but it cannot do system calls So it's very likely that you Can do a Scapi script with the exact same functionality as packet drill but if you look at If you look at this This one Doing a writer reader with Scapi is not that easy You can inject a packet Build a packet and inject it over an F packet, but you cannot test the system calls So the advantage packet is that you test packets and system calls together questions. Thanks a lot


Welcome back, you're watching from Logo to Impact. Now let's move on to our ad review segment. The one we're putting under the microscope today is the one that was conceived by Lowlyntas for OLX. It's shot to a song that was composed by Amit Trivedi. This entire ad film shows multiple scenarios from everyday life where people out of sheer laziness postpone selling their old stuff, trying to show of course how the date their attitude kills family aspirations. It's really a shout out to Procrastinators because of course there's a little bit of that in each one of us, isn't it? Here, OLX is a pioneer and they're obviously looking at one of the most fundamental reasons for this category not expanding or fundamental reasons that they need to kind of tap. And that being the usual habit or the tendency to postpone an expense. And which is what happens in this category. So I think the purpose is on terra firma. So it's absolutely bang on. One very good thing is that this is really a long-form, a mad jingle, kind of tends to drop in counter privatizing. But here thanks to probably the people who are behind this Amit Trivedi and all. It's like a music video more than an ad. And therefore it's quite sticky and you enjoy watching it throughout. And though it's a montage of several situations, they've been in each situation has been able to hold on to its own. So it's really, it's not like, you know, couple of them I like and couple of them I don't like. All of them kind of go above the average. So that's another very good attempt in terms of video. The biggest challenge here is of the editor. How do you cut a whole spa experience into little, little bathtubs? Finally when you get onto the television, the little second ages are going to be a challenge because the music video, as a music video, it works bang on. But as an ad, when it comes, you know, whether it has the same impact or not, I have my doubts. But that's where the challenge lies. Otherwise it's quite a good attempt. Hey, good one, yeah, good one. Did you change the drum kit? Yeah, let's see.
