this week we're looking at the Raspberry Pi 4 with 8 gigabytes RAM but we're gonna do something a little different as we install it in the super sleek super-spicy desktop case the Argonne one Beck has got your top news stories including a vulnerability and Intel processors that's been patched in Linux the look of the upcoming PS 5 gaming console and the unbelievable new Pyne Tab 10.1 inch HD tablet from Pine 64 finally crypto currency is finding its way to the banks and our crypto correspondent Robert Koenig will tell us all about JP Morgan's surprising change of heart as they begin accepting cryptocurrency and the Bank of Korea is seriously interested in digital currency this is all coming up so strap in it's time for the tech our live recordings are trusted only to solid-state drives by

Marshall and so many of you who have chosen to support category-five technology TV whether it be through our recent Kickstarter campaign or donating to ensure that category 5 made it safely into this studio space we do have those monthly expenses and it's astonishing how quickly a month is over and here we are I can't believe it's now mid-june so become a patron folks it is a great way to support category 5 TV if you love it I mean we give away the show for free and we always will and so I don't want you to ever feel like there's a cost involved in it but there are costs involved believe it or not and and it's up to our community coming together to help us to afford to be able to do this and I thank everyone who has helped us to be in this space and I love being here I miss my crew I'm miss having Jeff and Sasha and Henry join me in studio I really do but that time is coming and in the meantime I hope you're enjoying the content that I'm bringing you and the Beck is bringing you in the newsroom and that Robert is bringing you with the crypto corner we're all doing our best and we're working on ways to be able to broadcast the show as well as we can in this time and things are changing we'll see how things shape up over the next few weeks couple of months none of us really know what the timing looks like and what the space will look like at that point but we're doing everything we can and I'm so committed to bringing you new exciting content every single week and I hope you're loving it for I jump into the show this week I want you to make sure that you subscribe to us on our youtube channel that's a way you can support us without spending any money you can click that bell and you're gonna receive notifications whenever we're live or when I post new exciting content keep in mind we hit 25,000 subscribers on Linux tech show this week and as promised I am honorbound to do a fancy dance number for you I am so very sorry I've got my first choreography session this coming Saturday so I hope I don't hurt myself wish me luck and keep those subs coming okay it's Linux tech show com if you've never subscribed yet and who knows what will happen at 50,000 subscribers alright it's time to get into it folks and you know what happens when I do make her Tech it's time to steampunk it out let's do this because here's the thing you got to keep in mind the Raspberry Pi 4 is now available in models with 2 4 or even 8 gigabytes of RAM it supports decoding h.265 video up to 4k 60-plus h.264 Full HD it has dual HDMI output simple USB 3.0 and 2.0 ports Gigabit Ethernet 802 11 AC Wireless supporting both 2.4 and 5 gigahertz frequencies Bluetooth 5.0 and in case you didn't catch it I already mentioned it but it now has up to 8 gigabytes of ddr4 3200 RAM 8 gigabytes in an SBC folks what as the Raspberry Pi 4 is going to be in production until at least 2020 6 it's a great time to get into single board computers my friends or if you've already got a Raspberry Pi set up it's time to upgrade the specs of this particular Raspberry Pi are in line with a budget PC so we want to look at it and make it look like a sleek modern desktop device rather than just a piece of maker tech with a bunch of wires sticking out of the GPIO and that my friends is where the argon 1 case comes in this stylish aluminum alloy body the combination of both passive and active cooling it has both it's got a power button that safely controls the power state of your Raspberry Pi 4 and that's just a few of the points that make the argon 1 case a beautiful choice shall we get into it let's get our maker on folks alright first of all I've got the Raspberry Pi 4 with 8 gigabytes of RAM does it it looks like there's no tape on this box this these are the kind of boxes I like there we are alright it doesn't even have a that's crazy doesn't even have a anti-static bag so let's hope it didn't encounter any static along the way what else have we got in the box nothing a thing this is they don't touch that and a manual our right we've all seen a Raspberry Pi 4 we all know what they look like there it is folks it has the micro HDMI it's got the USB C power input it's got the headphone combination jack it's got USB to USB 3 Gigabit Ethernet 40 pin GPIO power over ethernet connector so you can buy an extra hat it's got a camera connector it's got video connector and it's got the SOC Wi-Fi chip everything else so we're familiar with that I don't need to get into too many details the argon 1 PI 4 case however and I should mention they do sell a PI 3 compatible argon one so keep that in mind however you can't intermix so if you're using an PI 4 you have to get the PI 4 model if you're using a PI 3 make sure you get the PI 3 model in our case we're going big or going home folks so let's get into it with the PI 4 8-gigabyte never been open before here we go let's see what is in this box paper what is it warranty card whatever what's this instructions on how to do you don't need these you're watching the video and presumably I'm gonna do a great job let's get into the bag ah there it is who cleans up the studio space anyways there's like weeks and weeks worth no I'm so kidding all right there's a protective film on the plastic bits and this my friends that is the argon one Raspberry Pi model for sorry Raspberry Pi for open up and see what's inside okay we've got this expansion board there it is this is cool so one of the things with a Raspberry Pi or any single board computer for the most part is that you've got these connectors all around the board so it's really hard to make it look nice on a shelf you've got the ethernet coming out one side you got HDMI coming out the other and power coming out here and video coming out here and Jeep and all that kind of stuff so what they've done is they've provided a basically an adapter that is going to simply plug in to the board to the headphone jack and the dual HDMI output and what does it do it puts all of those jacks directly onto the back of the Raspberry Pi so I'm just given that a nice snug little push I'm being careful I'm actually holding the the points on the board that I'm pushing so I don't accidentally break that off break the solder joints for that I don't know that it would happen but I want to be careful so there you have it so this is going to put the audio and the dual HDMI at the back along with USB USB 3 and Gigabit Ethernet further into the box okay we've got some thermal pads we're going to need those to make thermal contact with the SOC and the the RAM and here is the interior of the argon one case for the Raspberry Pi 4 so we can see a fan controller with GPIO GPIO riser pins so the Raspberry Pi 4 is going to connect with the GPIO so it's actually this is really really cool if I can show you internally so you're not losing the GPIO what it actually does is under this magnetic hood here if I can just get that off there we go it has the GPIO risen out from the board so here's where the actual GPIO is and it displaces it over here with a nice edge GPIO header identifier so you don't have to look for that card how cool is that so if you want to get into maker tech while this is looking so beautiful you can easily remove this magnetic cover and access the GPIO alright so let's get this thing assembled and put together so we can fire it up now I mentioned that this is both active and passive cooling so keep in mind while this is a plastic base for the for the argon one this is an aluminum cover okay so this is for heat dissipation the aluminum actually kind of pulls the heat away from the SOC and these are the two contacts so we've got one for the the SOC itself and one for the RAM and then we've got the active cooler so if it still gets too hot even though it is dissipating the heat through the aluminum then the fan which is on a fan controller will spin up to designated speeds that you specify based on temperatures I'm going to show you how all that works in just a few moments so I need this thermal pad which is going to make a nice little contact with with the S these are not the thermal pads these are feet whoa I was like hey thermal pad these are feet for the case this is gonna go right on here cool I can do that first can't I will do things out of order I'm sure that that's what the instructions say to do put the feet on first just like Ravi at category five that way I don't forget or lose them how many people have a whole bunch of these rubberized feet sitting in their tool chest there we go okay that's done now I can put those aside and now I do have these thermal pads which there we are they have like us an adhesive on either side so just peel that plastic make sure you do you don't want to put the plastic on there and have it melt on you when you're doing a TV show it's good to clip your nails for aesthetics it's terrible for peeling plastic off the back of an adhesive and that just goes right on there same with this one there we are and it's really really easy to put together it already is kind of preassembled boy oh boy if you have a choice do not clip your nails before doing this [Music] there we are didn't take any trouble at all isn't it great that the most challenging thing about installing this and doing this yourself to setup a Raspberry Pi for with 8 gigs of ram in an argon one the hardest thing was to get the sticky part the sticker cover off of the thermal pad ok so observe the GPIO the positioning of it and we're going to position that directly over the GPIO here careful not to bend any pins and I'm just going to turn this around so you can see this side as well and I'm just going to push that down nice and snug and it just goes in just like a GPIO should there we are make sure everything is aligned nicely and we've got all these screws I presume it's time to put them all together so it looks like I've got one two three four spots to screw in internally and then four for the cover so it's going to be these smaller screws on the inside and note that there is a hole on the Raspberry Pi where there is no standoff so you're not screwing into that and we're leaving these four outer ones for the bottom of the case so now I'm just gonna put that on top and grab the four longer screws and we're gonna put those ones in there we have it congratulations you did it you did it it wasn't that hard was it check out the ports on the back I love how sleek that looks notice there's no other ports all around we do have an SD micro SD port at the front kind of hidden away on the bottom however all of the i/o has been moved to the back I love that plus we've got this power button and it's just absolutely sleep we do have to take a quick break when we return I'm gonna fire this up and together we're gonna check out the features of the argon one case with the 8 gigabyte Raspberry Pi 4 stick around during the break I grabbed my micro SD card with the latest version of a Raspberry Pi OS on it I wanted to say raspbian but they've changed the name so it's called Raspberry Pi os now I tracked down my 5 volt 3.5 amp power supply and just keep in mind the Raspberry Pi 4 is a power-hungry beast so while I could probably power it with my 3 amp power supply or potentially even something a little bit less you could damage your SD card if there isn't enough power and that's surprisingly easy to do let's say I willy-nilly plug in a USB device that draws an amp or something from the USB port well there you go so I prefer to err on the side of caution so using a 3.5 amp power supply is just playing it safe that'll ensure that I get the best reliability out of my Raspberry Pi 4 alright with all the cables connected I'm going to fire up the Raspberry Pi 4 with a single press on the power button on the Aragon one and I can hear just a little spin of a fan I don't even think you'll be able to hear that with our compressors and everything else but it's just a slight I can tell that the fan has turned on and it's off and I am booted into my distro man that is great ok one thing I'm just gonna mention right out the gate because running cool feels good powered up great there's one thing that I think are gone one potentially misses the boat on and that's that we're still using the micro HDMI okay so I'm still having to use a micro HDMI to HDMI cable in order to plug this into my TV and into the capture devices so that you can see it at home however now while I feel like a bee they missed the boat on that they could have made it full HDMI they've got room for it they could have done that and besides they're in control of what they put on the case however as I move this around it's not janky at all there's no disconnection on the HDMI and I don't know about you but when I plug my Raspberry Pi board directly into an HDMI cable just like I've done with the argon one if I move it ever so slightly the screen goes green or it goes kind of digitally distorted or something and so I've got to jiggle that cable again and then if it ever gets moved I lose that connectivity and it causes problems well the argon one seems like even though it's still micro HDMI which mmm it's not the perfect connection for this kind of thing even though it is still micro HDMI it is significantly more solid than the micro HDMI that's built into the Raspberry Pi and I noticed that immediately so I think you will appreciate that as I mentioned I'm using an HD micro HDMI to HDMI cable you can also use a micro HDMI to full-sized HDMI adapter if you like and the argon one case is definitely giving me a better connection to that HDMI output alright I got a plug in a keyboard I've already plugged in my USB wireless mouse I've got my keyboard here and I'm just gonna plug that into the USB 2 because I'm gonna save those USB 3s for something else there we go alright so the firt Oh a little bit of latency there the first thing that I want to consider is I want to I mentioned that this is that this is a smart power switch so the power switch is programmable the heat dissipation the active heat cooler is actually programmable and I'm starting to feel a little bit of warmth there this is what's making me think of that cooling system so you can see there's vents at the side and this is doing a really good job of cooling the Raspberry Pi for however it is starting to get warm and I want that fan to come on if it starts to get a little bit too warm so it has that passive cooling from the aluminum and it has an active cooling system the fan that will turn on as needed so let's get into our terminal and I need to become root so I'm just gonna type sudo su - and there boom I am root so I am root you see the instructions that say to go curl and then the URL HTTP colon slash slash download dot argon-40 comm / argon and then it's one the number one SH and then a pipe why can't I think of the word bash okay so I want to break down that command for you okay what I'm actually doing is I'm telling it to use curl to download basically to the output this script from download argon-40 comm / argon one dot sh but instead of outputting it to my screen which is what would happen if I remove the pipe bash see that that's the script so the pipe bash says let's actually run that script in bash it's piping that output into bash so if I wanted to take a different approach and say I want to control what this is actually doing or I want to modify this installer the scripts before I actually install it well let's take a different approach so instead I'm going to W get that or I could have piped the curl so I'm gonna double you get o and it's kind of monkeyed with my terminal window there I'm going to ctrl C so that you can see that a little better W get oh there we go so W get is another download tool but this one is going to actually save the file to argon one SH now it's grabbing the I've got it and all I have to do in order to edit that file is I can use Nano for example so nano argon one dot Sh it's gonna bring it up into my favorite text editor alright so first thing that I see and I should say that one of the nice things about doing it this way is that you can inspect the code it's this is one of the things about open source and the way the Linux works is you can look through and see if there's anything that you want to change or whatever you want to do but so first of all I see a couple of functions just basically so that they can reuse some of the things like creating a file touching it and setting the permissions before adding the content check if a package is installed it's gonna allow them to see a response code of either ng which is presumably not good or okay if the package is not found in dpkg query and that is going to be called further down using this loop which grabs a package list like raspy - GPIO Python - our PI GPIO and so on and so forth so basically packages that are going to get installed with apt-get so then it goes through a loop here in package list and it goes through that loop installing and approving the installation of each of those packages but if any of the packages fail to install response with ng then it's gonna say hey there's something wrong you're not connected to the internet and it's going to die if however it because there's no else it's just going to resume if that doesn't happen so then it's going to move on to here so we've named the daemon Argan one D and we've got a power button script going to be created in user slash bin slash Argan 1d dot pi we've got a shutdown script in Lib system D called Argan D Argan one D dot - power off dot PI and so on and so forth so those are just the file names so that they can be reused alright these commands are enabling I squared C and I guess do serial that must be serial that's just my guess okay and then we're starting to write out the file so if the daemon config file does not let's create it so we touch it for some reason they're not using their their function here maybe that's a bug and we could fix it it doesn't matter it's doing exactly the same thing it's just funny that it it is happening redundantly they could have used the function these are comments and then at the bottom of the config file are the temperature to fan speed ratios so if it hits 55 degrees C it's gonna set the fan speed to 10% if it hits 60 degrees C it's gonna set the fan speed to 55 and 65 degrees Celsius is going to set the fan speed to a full 100% so hopefully we never hit that point so those configuration items of course they can be changed here before you install it or and that's just going to change the output of the daemon config file or of course you can edit that later or you can use the tool that they're going to give you in order to make those changes yourself shutdown script there we go see there use an argon create file now and this is a Python script that it is creating although it's running this in bash it's so what is doing is it's using the bash command to output to the shutdown script it's importing sis SM bus from Raspberry Pi GPIO as GPIO and I was checking the revision number of the Raspberry Pi and acting accordingly moving down power button script this is going to be what happens when you push that power button so again a Python script lets grabbing the bus it's grabbing the GPIO OS the time and that's not just the time that's the like the counter and the clock and everything else okay what's happening here so checks the revision again and acts accordingly because it may be a little bit different response based on the revision of the board so it's checking the shutdown check this is a function so yeah when you push the button it responds so when you push it when you okay so it's incrementing something called pulse time that's a an integer string that well not an integer string but an integer that's incrementing and every time you push the button it's kind of it's counting that so when you push it twice it's going to safely reboot the the Raspberry Pi now note what's actually happening when you push that button twice is that it's running the OS system command reboot so it's not doing a hard reboot is not cutting power and then powering it back on no it's actually running the reboot command that I would run in my bash prompt so it's a safe reboot it's going to automatically sync your SSD it's gonna save your files and whatever else that it normally would do during a reboot command you can also add your own stuff here if you wanted to like I could do something like remember this is this is even though we're typing this in bash this is going to be a Python script so you could put any Python here any Python and then just make sure that you pipe that with not pipe but direct that to dollar sign power button script you could also edit that that file at any time you could edit that power button script which is if you go back up it's going to be saved power button script slash user slash bin slash argon 1d dot pi so you can edit that script and then you'll be able to change the what it does when you push the power button twice or when you hold it in for three seconds and and you can make it react the way you want maybe you want it to send you an email or something like that you can do that or you have something else like a APC UPS that you want to have safely turned off or something after a 30 second time or I don't know maybe you've got a watchdog plugged into the GPIO you can use that as well okay so if you push the button for if you long press for three seconds it's going to run shutdown now - eh so that's actually a safe shutdown command to power off your computer so you're not just killing power like you would if you continue to hold in that button for five seconds which is not a safe way to do it that's like your last resort but this script is as you can see running those commands as you normally would safely so you push that button triggers the gpio and it's monitoring how long you press it or how many times you press it and then it reacts accordingly so with a little python knowledge you could make that do whatever you want if I push it three times I want it to play my favorite song that kind of stuff whatever you think you can look through here lots of fun so I love that as you know people who like to look under the hood we can do so and then when we're done say we've made some changes we can control o enter to write our changes and then control X to exit and now I just need to go chmod plus x are gone one dot Sh and now I can run that by going dot slash argon one dot Sh just like that which is exactly the same as using curl the URL typing it into bash and I'm going to run that here we go it's already got GPIO it's already got a couple of the things that are gone one is needing I squared C is already installed and active and ready to go and we're done shortcuts created okay what oh yeah look at that there are actually shortcuts on my desktop all right argon one configuration let's run it we're gonna execute that in a terminal all right argon one fan speed configuration tool this will remove existing configurations press Y alright what do you wanna do always-on let's try it yeah I hear it you guys hear that it's so quiet even at on that's pretty good I'm pleased with that however because it is controlled by an I squared C controller rather than just a GPIO pin it's not just on or off it's you're able to set the threshold so that's where we can run that configuration script again and say adjust the temperature so let's bring that up on our screen a little bit I'm having trouble seeing that on my screen okay so please provide fan speeds for the following temperatures 55 C let's do 25% fan speed 60 C let's do 50% fan speed 65 C all right 90% okay so now the fan just shut right off because it is using the passive cooling to keep that thing below 55 I think it was so it's completely silent if I start using my raspberry pi to death it's going to spin up that fan alright so now that I've got that script installed presumably if I push the power button it's not going to do anything nothing however if I push it two times what's it going to do and we're gonna lose the screen here but if it works we know and there it goes and now notice it's not killing the power I don't know if you can see that but it is actually done a safe reboot that's fantastic that is the Raspberry Pi 4 with 8 gigabytes of RAM plus the argon one case those are just fantastic products I'm really really pleased with this I love that I can still access the GPIO without having to take apart the case that's cool just absolutely gorgeous we've got a head over to the newsroom folks I hope you enjoyed that segment we've got some great news stories for you so here is Becca here's what's coming up in the category 5 TV newsroom the latest Intel crosstalk vulnerability has been patched in Debian CentOS and Red Hat Enterprise Linux Sony has unveiled the look of the PS 5 Facebook's giphy takeover is being halted while the UK competition and Markets Authority investigate the deal researchers have discovered a way to record audio in real time by focusing a telescope on a distant light bulb and the pine tab Linux tablet from Pine 64 is now available for pre-order and you can get one for just $100 stick around the full details and this week's crypto corner are coming up this is the category five dot TV newsroom covering the week's top texture with a slight linux bias from the newsroom I'm Becca Ferguson the latest Intel crosstalk vulnerability is now patched in Debian gnu/linux sent OS Linux as well as Red Hat Enterprise Linux systems the recently found hardware vulnerability known as crosstalk was discovered by researchers from view university Amsterdam in some Intel processors the flaw could allow local attackers or virtual machine guests to expose sensitive information like cryptographic keys from other users or VMS already patched in all supported Ubuntu releases the vulnerability has also now been patched in Debian Buster and stretch plus sent OS 6 & 7 as well as Red Hat Enterprise Linux version 6 & 7 to mitigate the vulnerability in their systems users will have to install the latest Linux kernel and Intel micro code updates which are now available in the stable software repositories of their distributions although Debian stretch users must enable the non free repository to get the patch make sure you reboot your systems after installing the new Linux kernel and Intel micro code updates Sony has given gamers a first look at the design of its next console as well as some of the titles it will play due to the corona virus pandemic Sony opted to stream a pre-recorded video rather than host a live event the PlayStation 5 has a black core surrounded by curved white edging and a blue glow to follow ups two best-selling ps4 releases were among the standout games announcements spider-man Miles Morales and horizon for bid in West Sony's machine will launch alongside Microsoft's rival Xbox series X before the end of the year so many people remarked that the console looked like a Wi-Fi router that the term trended on Twitter shortly after the event more than two dozen new games were shown off in total other highlights included a first look at Sony's racing game Gran Turismo 7 and a brief look at Cap Korn Capcom's zombie horror game Resident Evil 8 the play station five is set to go on sale later this year seven years after the ps4 in addition to being able to deliver improve visuals the new machine also has a customized harddrive that will make it possible to radically reduce load times sony is building a library of launch titles that will only be available on its next-generation machine including some brand new titles never-before-seen one of the more unusual games was stray a third-person cat adventure that set in a neon-lit cyber city there was no mention of any virtual reality games however nor was there any mention of a PlayStation 5 version of the Last of Us 2 rather than a quantum leap this next generation looks like it might be built around lots of smaller improvements in areas like audio with 3d sound and improved haptic feedback in the controller beyond better visuals and faster loading times what does the next generation actually mean when it comes to games on this evidence more of the same shooters racers third-person adventure titles and sports games things we already have but graphically improved Facebook's takeover of Gylfie a search engine for funny reaction images is being investigated by the UK's competition authority jiffy's vast library of looping short video animations is hugely popular in Facebook's apps but it also provides animations to competitors like tick-tock snapchat snapchat snapchat and Twitter now the UK competition in markets authority CMA is investigating whether the purchase is a problem it has sent an enforcement order to Facebook effectively putting a hold on any merging of the companies until its investigation is over announcing the acquisition in May this year facebook said that half of jiffy's traffic comes from facebook apps including whatsapp and Instagram but it also said that the deal worth a reported four hundred million dollars would not affect deals in place with other partners the CMA however said it was investigating whether or not the acquisition may be expected to result in a substantial lessening of competition but the enforcement means Facebook has to keep the jiffy company staff and Technology separate from Facebook itself unless it gets advanced written permission from the CMA it is not the first time concerns have been raised about the Facebook Jaffe deal with questions raised over the level of access Facebook would have to its competitors data through the service the CMA is inviting comments until July 3rd with no date set for its decision the pine tab Linux tablet from pine sixty-four is now available for pre-order becca has these stories coming up plus roberts here with the crypto corner don't go anywhere welcome to the cryptic horn as usual we'll start with the market the market hasn't changed significantly in the total volume 270 billion it was similar to last week but there has been a dip in the last few days and the market hasn't recovered since then although as you can see last 24 hours most of the coins are in in green so a Bitcoin is now at four 9450 for US dollars and if we sought by seven days you will see that a few coins had some fantastic gains I mean we've got birch with seventy seven point five percent gain and in total that fifteen tokens coins that had again over fifteen percent and if we sought by dance above negative we only had two coins that had done trend towards trend over 15% it shows that the market is maturing and growing as it was also last week if we look at my favorite subject decentralized fineness defy market this one is grown by almost 1 billion in one week it was last week 2.4 billion now it's 3.3 billion the biggest one is now compound as you remember from last week and previous weeks with maker Dow is the number one and that has changed now and by a significant difference it's now compound being the number one with a growth in 24 hours of over 40 percent so this market is heating up and it's getting more and more interesting from day to day now another subject is and this this is interesting for everybody here because you hear so many opinions on how the market is performing it's going up it's going down the future's going bright it's dark and I just want to show you one example of what has happened in the past and it is here JP Morgan their CEO Jamie Dimon said this was in 2000 safety 17 he said that bitcoin is a fraud and that everybody would fire everybody and he said that openly in the forum and he would fire every about everyone in the bank that is trading Bitcoin in a second now interesting enough if we look into the news from this week we see that JP Morgan completely surprised surprises with a bet bit coin flip so now they know supporting Bitcoin and that's the interesting part you need to really form your own opinion in this market don't listen to the so-called experts because you see JP Morgan one of the biggest banks in the world suddenly changes the opinion overnight and so they're not real experts you're the own expert just form your own opinion when you follow a coin or you want to do an investment next one is an analysis on the on the development of some coins and its outlier ventures that did an analysis and which was quite interesting so they see that there has been a downturn in development for around 20% in average but some again as polka-dot has got increased in substantial rise in develop activity polka-dot in Cosmos 15% and theta and Caetano increased the core development significantly it's interesting because they did a very thorough analysis on on how the market is card developing from the technological point of view the development and so on I will put a link of this PDF file in in the in the in the description next headline is you remember China they have launched already their cryptocurrency the fiat cryptocurrency in our Korea is doing the same thing they're applying the issues everybody every countries suddenly jumping on this strain of having a cryptocurrency back system next one is an analysis last week I reported about PwC analysis on the hedge fund industry and here this one was done by fidelity digital assets and they've got some interesting findings too so a survey of 800 institutional investors in the US and Europe found almost 80 percent intrigued by digital assets with 36% already invested in the market and broken down by market it looks like Europe it seems to be more bullish than the US because only 27% of the institutions of the u.s. institutions now that includes pension funds family offices investment advisors in digital and transitional hedge funds have invested in cryptocurrencies but this is up from 22% a year ago so it went up by 5% it's an interesting development I would say and it shows that the investors in the investment market is participating in our industry and last but not least is and I put also a link of that report in the in the show notes last one is the human rights foundation launched a Bitcoin Development Fund and so the HRF launches a fund to support developers who are making the Bitcoin more private and decentralized and resilient so that it can be better that it can better serve as a financial tool for human right activists I find that also interesting that human rights foundation is supporting with cash developers to make our Bitcoin a little bit more private so that's it for me this week I hope I hope you enjoyed it and I'm looking forward to see you next week with some I guarantee you fantastic news and yeah until then I wish you great week and thank you very much for watching thank you Robert just a reminder that we're not providing financial advice but simply sharing what's happening in the cryptocurrency market always remember that the cryptocurrency markets are ever-changing always volatile so you should only spend what you can afford to lose now back to Becca in the newsroom Thank You Robbie in an era of digital eavesdropping where hackers employ a variety of means to take over built-in video cameras peruse personal digital data and snoop on cellular conversations researchers have seen the light literally viewers in the UK will want to make sure their license is up-to-date because here's an upgrade the BBC might want to add to their TV detector vans Israeli researchers report that they successfully tapped into speech and music inside an apartment simply by focusing on a light bulb in a paper published over the weekend the researchers said all they needed were a telescope and a $400 optical sensor which they used to measure barely perceptible light bulb vibrations triggered by either voices or music in the room the research team conducted the test by pointing a telescope towards a light bulb in an apartment building 27 yards away capturing the vibrations from the ball they were able to reconstruct with fair quality let it be by the Beatles clocks by Coldplay and a snippet of a speech by President Trump the researchers said we show how fluctuations in the air pressure on the surface of the hanging bulb in response to sound which caused the bulb to vibrate very slightly Amil a debris vibration can be exploited by eavesdroppers to recover speech and singing passively externally and in real time they noted that a direct line of sight to the bulb is required lampshades or window curtains will prevent it from working also the test sounds were played at maximum volume the approach called lamp phone is an improvement over recent developments in eavesdropping technology Ben nasi a developer of the program explained any sound in the room can be recovered from the room with no requirement to hack anything and no device in the room you just need line of sight to head to a hanging bulb and this is it previous comparable approaches include the memorable 2014 visual microphone developed by MIT Microsoft and Adobe that reconstructed speech and music from a room by analyzing micro vibrations from a bag of potato chips sitting on a table while impressive the device required massive computational power and much time to analyze recorded vibrations lamp phone can be conducted in real-time the wait is finally over as the pine table pre-orders
