I at least hope they sell/give away those machines to keep them in circulation. I'd be a real shame to have modern and environmentally expensive hardware like that be torn apart for scrap metal in a recycling facility. Many tech companies love the "eco-friendly" trade in programs that essentially serve to take working, used devices out of circulation.

Security shouldn't be much of an issue with most modern CPUs. The microcode can be updated at boot time by the kernel, even if the one loaded by the BIOS is out of date. So microcode level patches are taken care of.

That leaves attacks on secure boot, which could be feasible with a bad implementation, but I doubt most home users would have to worry about an evil maid attack.

Yeah, that doesn't make any sense at all. The only reason I can think of to use WAV instead of a losslessly compressed FLAC is if the player being used has a dog slow CPU or an incredibly old software stack that can't play FLAC files.

But I doubt these guys are using a Pentium 1 machine to play their audio files so idk. The low end smartphone I had in 2013 could easily play FLAC files, at least in the real time uncompressing and decoding part of the equation. Now if the built in DAC and amplifier could take advantage of that extra data is another thing.

If we're going to base the reliability of a connector by a single example my 6 year old phone still holds cables as snuggly as day one. I can grab it from the cable and it doesn't fall. Maybe if I try to treat it like a whip it will but that's outside a reasonable use case. The cable is not 6 years old mind you, close to 3. But the connector aside from pulling gunk out with a needle a few times works perfectly.

The only way would be to let the thing run and say, pipe the output to grep looking for your password or something else you're looking for. SIMD instructions are used very often for parsing text so I wouldn't be surprised if sensitive passwords eventually get loaded into an YMM register and the exploit just so happened to dump that.

Install the nasm package. It's probably not included in build-essencial.

I had to run make on the uncompressed folder. Perhaps the build-essential package doesn't come with NASM in Ubuntu? I'll need a bit more info on the error if you want me to try and help you :)

This is incredibly scary. On my Zen 2 box (Ryzen 3600) logging the output of the exploit running as an unprivileged user while copying and pasting a string into a text editor in the background (I used Kate), resulted in pieces of the string being logged into the output of zenbleed. And this is after a few seconds of runtime mind you, not even a full minute.

Thankfully the exploit is highly dependent on a specific asm routine so exploiting it from JS or WASM in a browser should be extremely difficult. Otherwise a nefarious tab left open for hours in the background could exfiltrate without an issue.

I'm eagerly waiting for Fedora maintainers to push the new microcode so the kernel can update it during the boot process.

I would imagine that this translates to lower power consumption when doing the same tasks. Something that would require the CPU in a current phone to work hard for a couple of seconds, like calculating possible routes in Google Maps, being able to be completed in less than one would make a difference. Especially if we do this kinds of tasks thousands of times throughout the day.

Sadly this will probably mean some apps will be able to steal more CPU time for doing telemetry and serving ads because the user won't notice a difference in response time and performance.

I took that as an, I don't have time to learn a new platform so I stick with what works for me, which is valid.

I'm not sure if this really saves time in the end. At least for me the part of taking a lot of information and thinking about condensing it in a few sentences is the most important part of making flashcards or similar summaries.

A lot of the time I end up never reading them, or reading them once because I already indirectly studied everything in the process of making them in the first place.

The ATmega 328P an Arduino Uno or Nano uses has 2KB of memory and 32KB of flash storage for the program. Having some sort of micropython interpreter there would be impossible, and even if it could be achieved, somone still has to write the low level C/ASM code to make it all work. For many embedded systems, low level languages like C or C++ (perhaps Rust for a lot of ARM micros) is the only sensible choice. If it's not a multi user system that's connected to a network, people trying to abuse memory unsafe code isn't a concern.

ARM CPU manufacturers have been doing that for more than a decade :)

Fortunately I have gotten much better at managing it compared to when I was a child but still, thinking of doing something like teach a class is nearly unthinkable to me. I just don't know how people manage to talk while deeply concentrated in something. I have to think about pacing myself otherwise whoever is in the other end will have trouble understanding anything at all.

That and appearing like I'm stuck thinking about something while in reality the whole answer is already formulated in my mind and I'm just having trouble saying it out-loud. At least I'm decently good at coming up with synonyms on the spot :)

It's not a killer deal for the consumer. That's just Nvidia fucking you over either way and still profiting off it. The market is not only bad in the high end, but there aren't any ~$200 value oriented graphics cards that provide significant upgrades over past generations. Just now the GTX 1060 has stepped down from being the most popular card in Steam's hardware survey just to be replaced by the GTX 1650, a much newer card that costs about the same and performs about the same. And with less VRAM!

I prefer to wear a tin foil suit thank you.

Some people prefer to trade off stability for a slight performance improvement. With modern hardware I don't think it's worth it to be honest. I want my computer to work day in and day out even if it means a 2% lower score in some benchmark.

Maybe I'm weird in a way but I never saw the appeal of social media besides casually keeping in touch with friends. I have social media accounts but almost everyone I have added as a friend are people that I know in real life. I never feel the urge to check compulsively to see what they've posted.

Although it would be hypercritical in my part to not point out that I do waste a lot more time in websites like Reddit or Hacker News where I'm anonymous but still talk with others so it is a kind of social media. I guess it would be very difficult for me to go completely free of social media. Even though I rarely use Twitter, Instagram or Facebook.

And redo the decades of work put into the userspace applications for existing operating systems?

oh shit I did. I doubt elevators run KDE or have dual core processors lol

Close, it was to kill the stupid wifi blacklist but just to upgrade the wireless n card with an ac one I had lying around form a broken machine.

If you're turning in a crammed elevator you could be momentarily pressing multiple buttons with your backpack. That would most definitely be annoying for everyone.

I remember having to flash the spi chip with a raspberry pi, flashrom and janky wiring on an oldish Thinkpad. Not so good times :)

Most modern low end boards don't have this. And a very big chunk of desktop computers in use nowadays probably fall in the having a low end board category or being old enough for that to not be a feature. (my desktop is in the first category lol)

I really enjoyed a piece of coursework that I was given on a discrete mathematics course that consisted of implementing RSA using the math theory taught in class. It's a very clever algorithm.

The interesting thing about this is that it's a RISC-V machine, at least for me. A few years ago RISC-V dev boards were much more expensive than their ARM counterparts, nowadays they still are but are getting closer in price parity.

If you want to maximize for longevity, picking something that existed for 30 years like vi or emacs is probably your best bet.

I'm from Argentina and consume it on a regular basis. I haven't noticed any pigmentation, although I have the habit to rinse my mouth after finishing a cup of anything that's not water so that might be why.

That thing must have been expensive back when it was new. The flash drive I carry in my keychain nowadays was like $8 new lol

Oh boy I remember when Gnome's file manager ate all my ram trying to generate thumbnails for a folder with millions of images.

And when Dolphin crashed and refused to work again when the nfs shares that were mounted got unexpectedly disconnected from the network. I had to unmount everything from the terminal before Dolphin decided to work again.
