here's what's coming up in the category 5 tv newsroom the public beta of spacex starlink internet service has begun youtube dl has been hit with a dmca takedown by the riaa ubuntu groovy gorilla as raspberry pi as a first-class citizen zoom has added end-to-end encryption for all for free though there are caveats and will tell you what they are and a nasa spacecraft spacecraft successfully touched down on an asteroid to collect a sample stick around the full details and this week's crypto corner are coming up this is the category 5.tv newsroom covering the week's top tech stories with a slight linux bias from the newsroom i'm becca ferguson the public beta space of spacex starlink spacex has begun sending email invitations to starling's public beta and will charge beta users 99 per month plus a one-time fee of 499 dollars for the user terminal mounting tripod and router the emails are being sent to people who previously registered interest in the service on the starlink website spacex is calling it the better than nothing beta perhaps partly because the starlink satellite service will be most useful to people who can't get cable or fiber broadband but the email also says as you can tell from the title we are trying to lower your initial expectations the email reads expect to see data speeds vary from 50 to megabits per second and latency from 20 to 40 milliseconds over the next several months as we enhance the starlink system there will also be brief periods of no connectivity at all as we launch more satellites install more ground stations and improve our networking software data speed latency and uptime will improve dramatically for latency we expect to achieve 16 to 19 milliseconds by summer 2021. there is apparently no data cap a starlink mobile app to help beta users set up and manage the surface also just went live on apple's app store and google play elon musk recently said that the public beta will be for the northern u.s and hopefully southern canada spacex plans to provide starlink to a school district in texas in early 2021 but that doesn't mean the public beta is available to anyone in the south the wait may not be too long though as spacex has said it will reach near global coverage of the populated world by 2021. you know that starling story is an interesting one because for so long we have been hearing about this project and hearing about how it's going to change the face of the globe with providing internet high-speed internet to you know unreachable areas so it's interesting that they're offering this beta version to lower expectations that's totally contrary to what companies do they want to heighten expectations so why would they take that approach when quite frankly if you don't have access to internet even to hear that you can get you know 50 make download speeds is phenomenal sure like that that to me is great i mean but it's satellite you expect that there's going to be downtime you expect that there's going to be interference from weather so i don't understand why they would call this about lowering expectations like what were people thinking they were going to well i mean we know that it's meant to be really really fast and they're saying it's not yet there no so let's try it out but no it's not yet there yeah so i think you know they have to set expectations perhaps to avoid you know complaints and things like that but i think about like my you it's it's hard for us to fathom if we live in a city that there are places still that don't have high-speed internet i i'm literally thinking about my church yeah we are yeah you're just on the outskirts we're less than a kilometer from the edge of barry we cannot get anything internet wise other than sure your basic dsl our old studio studio d brutal same deal my father-in-law is using lte internet at home because they do not have high-speed internet where they live that's what we have at the church that's unreal 200 bucks a month just to have basic internet just for basic lte internet man so i mean like this star link for the price it's going to be could be a great option yes for you for you then in that case or for my father-in-law it's a great option and it's probably going to be better than what they currently have so maybe setting the expectations low in that you know those of us who have gig internet going out and signing up for the new you know this is the latest and greatest from spacex right so it's going to be the best well they're setting the expectations low purposefully so that it's the right market yeah i i guess if you're in a city where you've got that high speed but if you have nothing yes i mean what they're offering for speeds is phenomenal it is so i mean i'm i'm excited at first i wasn't sure how i felt about this project when i first heard about it because i'm like oh he just wants to space debris yeah but now that i'm starting to see it roll out i'm getting excited about but what's interesting is that it's upper u.s possibly lower canada for their base start why not beta test in like a low cert like pick somewhere along the equator of africa maybe you know like some remote well it makes sense though that they would want to test it in a place where well think of it this way if if it went down i have something else to fall back on yeah i have the 4g infrastructure to fall back on if i need it so maybe that has something to do with it i mean we're speculating here but there there are so many thoughts yeah but hey how how does something like starlink affect you is it something that would be better than what you have or is it a severe downgrade that's really what it comes down to but i think in a lot of cases this is going to bring high-speed internet to areas that currently don't have it and not only that jeff but we've hit on it in the past when we've talked about starlink and that's that in an event of natural disaster or infrastructure issues it's an opportunity to still receive good solid internet high-speed internet that is not reliant on things like towers yes right now one of the things that will be interesting is because i mean this is not new like satellite is already well good satellite internet what's new that's that's the challenge here is uh i mean i used to another iteration of my working life i was a uh a recognized installer for satellite um so i have an inner working of or an inner understanding of how it works and it was quite uh cumbersome and unreliable yep i mean the dish moves just a slight bit from wind right and you're out so i'm really interested to see how starlink's internet works in that regard and if a little bit of wind is going to knock it out or if it's a more stable platform time will tell maybe the beta test will show some results so we'll see over the next couple months we've got to head back to becca youtube dl has been hit with a dmca takedown by the recording industry association of america the ri double a has issued a dmca takedown on the open source project youtube dl on their github repository this is done under the guise of protecting content creators from having their ad revenue stolen youtube dl however is often used by archivists and users who suffer from a slow internet connection in order to allow them to watch the content there are of course those that use it to circumvent ads but we can't pretend ad blockers don't exist which accomplish the same goal with less effort so are ad blockers next on the list here at category 5 we're content creators we post our videos on youtube and we depend on the revenue it generates but like the electronic frontier foundation points out we believe youtube dl is a legitimate tool with a world of lawful uses see we know we have viewers who are watching in areas where internet just isn't very good we've heard from troops who watch our show in their tents while at war we have fans who live in areas where high-speed internet just doesn't exist yet so we make sure they have access to our content for free with the hope that they will support us through patreon if they're able we received an email from a viewer this week asking us how they can watch our show while circumventing youtube is it surprising that we the very content creators who rely on the revenue youtube provides responded by providing bittorrent files of all 13 past seasons plus recommended the download button found on the page of every episode we publish on our website as content creators we understand the need for revenue it costs a lot of money to do what we do but for the riaa to demand youtube dl be shut down seems shady the electronic frontier foundation fights these types of battles on behalf of open source projects you can help protect projects like youtube dl by donating at eff.org last week canonical released the latest intermediate version of ubuntu 20.10 groovy gorilla which for the first time adds first-class platform support for the raspberry pi 4. groovy gorilla itself is a pretty typical interim release offering an updated gnome version with lots of bug fixes and small feature additions support has also been added for windows active directory in the ubiquiti os installer itself and while it has been possible for some time to install ubuntu on raspberry pi hardware up until now that has been strictly a community effort the pie itself ships with raspberry pi os at debian based distribution whose origins began with the pie community but which has since been officially adopted and supported by the raspberry pi foundation itself while canonical added the pi as a supported platform in 20.04 earlier this year that support was only for the ubuntu server distribution not desktop with 20.10 groovy gorilla canonical has added full desktop support for the pi 4. martin wim press canonical's director of engineering for the ubuntu desktop says this means the pi is now a first-class citizen canonical guarantees the same level of integration q a and support from kernel to user space that it does for a standard pc the entire ubuntu software repository is available and supported on the pi of course that's other than architecture-specific packages that start with names like i386 and are therefore not compatible with the raspberry pi's arm processor if you'd like to install ubuntu 20.10 desktop on the pi you'll need a four gigabyte or eight gigabyte raspberry pi as long as you meet the hardware requirements the install is a breeze ubuntu 20.10 desktop is an option in the standard raspberry pi imager now the imager itself is available for linux windows or mac platforms to get up and running insert a four gigabyte plus microsd card open the imager choose ubuntu 20.10 and click right a few minutes later you'll be able to boot the official ubuntu 20.10 for raspberry pi 4. all for free though there are caveats and we'll tell you what they are and a nasa spacecraft successfully touched down on an asteroid to collect a sample becca has these stories coming up plus robert is here with the crypto corner don't go anywhere [Music] welcome back to the world of cryptos and welcome back to the crypto corner this week i've got some really good news for you um if we look at the market by the time i'm recording this year the price of bitcoin is at 13 128 which is equivalent to 2.3 increase in the last 24 hours and 14 in the last seven days i think that's fantastic news and one reason why i believe that is if we compare it to the stock exchange the u.s stock exchange or the gold price then there is a decoupling happening it is not confirmed yet that will take some time but at least there is a decoupling at the moment this is the charge chart since beginning of october and the red line is the red curve is the u.s stock exchange the blue is the gold price and so you see there's a significant gap especially since yesterday where we had a huge drop in the stock exchange in the air stock exchange uh to bitcoin so i think that's that's great news it's to be expected because it's a complete uh different asset commodity and so let's see what will happen the other good news is paypal paypal decided to get involved in cryptocurrencies and so you can buy now uh some cryptocurrencies on their platform and the great news is because they have got over 340 million users and you can uh by using paypal pay for services and goods and you can now use for example bitcoin to pay for services and goods but at least that the offering this year to this huge community is i think fantastic news also one that i have to take with a smile is our friends from jp morgan uh one of the largest financial institutions in the world and in 2017 jamie dimon their ceo said that bitcoin is a fraud and will blow up jose said that he if he finds somebody in his organization uh trading uh cryptocurrencies that person will be fired on the spot now like in politics things can change significantly and dramatically and so this is uh happened uh this was published uh two days ago uh by jp morgan where they're now saying bitcoin has considerable upside as it's better competes with gold as an alternative currency i find that fantastic news because the organization embedded in the old system like jp morgan suddenly changes their opinion 180 degrees is for me extremely bullish not financial advice but for me that's a bullish sign so um yeah one thing i'd like to focus on is it's a question that a lot of people are asking us in regards to private keys and public keys so i'd like to spend a few minutes on that subject and for that i pulled up a website called ian callman.io because this is uses um the web the the content fantastically well and uh so there's somebody in bitcoin or team that came up with this process of how to convert a private key into a public key and they expanded that and now a lot of different cryptocurrencies are using the same process and that's why it's called bip 39 or bip 44 because this bitcoin improvement protocol but other uh currencies are using that so i just gen clicked on generated on 24 words and so out of a repository uh the system generated 24 words and that those are the words that you need to remember when you generate a wallet for example you create a new wallet the wallet will generate those 24 words and those are the ones that you have to remember because everything derives from those 24 words so with a little bit this little bit technical here but from those 24 words we deduct the private key from that private key we deduct the public key and that public key and then generates the address yeah so and the reason that is done is that there is no way in the world that you can get back to the private key that's why cryptocurrency is so secure yeah and so what you do is you take the private key you hash it that's a special crypto cryptographic process and with that you generate the public key and the public key is hashed twice and that generates the address the reason that this is done is that there might be future some computers that are able to deduct from the public key the private key there don't exist yet but we're thinking well ahead in the future and that's why we are using the address as the key that you send to other people in case you want to receive some bitcoin or so so um this is all the magic behind it it's based on those 24 words those 24 words generate the private key the private key generates the public key and the public key generates the address and address is what we use and that set is used in many other ikea cryptocurrencies they use the same same process anyway that's it from me i hope you enjoyed it i hope you learned something um thank you very much for watching please leave a like it helps us we need to grow and um yeah come back next week thank you very much for watching bye thank you robert just a reminder that we're not providing financial advice but only sharing what's happening in the cryptocurrency markets always remember that the cryptocurrency markets are ever changing and always volatile so only invest what you can afford to lose now here's becca thank you robbie zoom has added end-to-end encryption to his video conferencing service at no additional cost for all users whether they are paying subscribers or not the feature has been long awaited given the service's massive adoption as a result of pandemic lockdowns something that swung a spotlight on its patchy security the company announced on tuesday that the new feature is available now as a technical preview for the next 30 days and is looking for user feedback before rolling it out on mass zoom see so jason lee gives kudos to keybase who joined the company in may to develop the security feature taking just six months to do so zoom says its end-to-end encryption will use 256-bit aes gcm and a secure key exchange is performed beforehand to ensure only the participants on the call can decrypt each other's part of the conversations and no eavesdroppers not even zoom itself can listen in zoom already encrypted some of its communications though it wasn't truly end to end until now in order to use the end-to-end encryption an account admin has to enable the feature zoom's end-to-end encryption is limited to 200 participants so for larger meetings where encryption may not be a needed feature such as a public forum or a digital comic con it can be disabled to allow more people to join other restrictions of the service are a lack of cloud recording and live transcription breakout rooms polling and one-to-one private chats are also unavailable when end-to-end encryption are on as are live emojis perhaps the biggest caveat of all though is that each user must have the official zoom client installed in order to participate so browser-based participation will not be available for encrypted meetings third-party zoom clients will also not work when end-to-end encryption is enabled the feature is available on new releases of the zoom software for mac os windows android linux and ios after orbiting the near-earth asteroid bennu for nearly two years nasa's osiris-rex spacecraft successfully touched down and reached out its robotic arm to collect a sample from the asteroid's surface last week the sample will be returned to earth in 2023 to achieve this historic first for nasa a van sized spacecraft had to briefly touch down its arm in a landing site called nightingale the site is the width of a few parking spaces the arm reached out to collect a sample which could be between two ounces and two kilograms then the spacecraft backed away to safety we have never done this before we're actually going to collect a sample and bring it back down to earth for further examination by scientists in order to achieve that objective the osiris-rex spacecraft has been navigating around bennu for about the last two years studying in great detail and also overcoming a number of challenges that bennu has presented we were looking for locations on venue that were 50 meters in diameter relatively flat and covered with fine grained material and by fine-grained material i mean stuff that's the size of a dime or smaller we realized that there were no sites on bennu that even came close to meeting this criteria everywhere we looked was too small and covered with boulders so we actually had to fly a number of additional close passes over the asteroid and rethink our entire plan for grabbing the sample the tag event is our touch and go event which is where we'll actually be retrieving the sample from asteroid bennu we start with a series of maneuvers one of them being the checkpoint burn which is where we'll actually check our position velocity in relation to the sample sites and then the match point burn about 10 minutes later we'll zero out our horizontal velocity relative to the surface and then about 10 minutes after that we make contact with the tag sam fire the gas bottle and then back away and we hope to get at least 60 grams of sample and then we'll be able to store that and bring it back down to earth everything went perfectly based on the data returned by the spacecraft according to dante loretta the mission's principal investigator and a professor at the university of arizona lunar and planetary laboratory he said he feels transcendent and the team is exuberant based on the current data loretta said in a statement after over a decade of planning the team is overjoyed at the success of today's sampling attempt i look forward to analyzing the data and to determine the mass of sample collected we have to verify that we have a proper sample first we're going to image the tag sam head by sticking in front of one of the cameras then we're going to do a maneuver called the sample mass measurement in which we stick out the arm and we spin the spacecraft in order for us to decide if we've collected enough mass to be able to stow and return home or if we have to try again preliminary data show the sampling head touch bennu's surface for approximately six seconds after which the spacecraft performed a back away burn thomas zerbuckin associate administrator for nasa's science mission directorate said in a statement a piece of primordial rock that has witnessed our solar system's entire history may now be ready to come home for generations of scientific discovery and we can't wait to see what comes next the mission which stands for origin spectral interpretation resource identification security regolith explorer launched in september 2016. since arriving at bennu the spacecraft and its cameras have been collecting and sending back data and images to help the team learn more about the asteroids composition and map out the best potential landing sites to collect samples the main event of the mission is the touch and go sample collection event or tag that occurred last week the event took about four and a half hours total to unfold and the spacecraft executed three maneuvers to collect the sample from which could help scientists understand not only more about asteroids that could impact earth but also about how planets formed and life began big thanks to roy w nash and our community of viewers for submitting stories to us this week thanks for
