  • WiFi signals can measure heart rate—no wearables needed

  • The problem is not sharing and accessing, but generating. If we had a system where people would be paid for generating knowledge, then they wouldn't have to charge for accessing knowledge.

    That's why a lot more research should be paid for by the government. In exchange, government-funded research would be excluded from having patents and/or copyright.

  • UK government trial of Microsoft's M365 Copilot finds no clear productivity boost

  • Yeah, shitty toy ones. This here is about productivity, not about a hobby. And not even real state-of-the-art models were able to actually give a productivity advantage.

  • ELI 15: How do phone manufacturers "lock" bootloaders? Is that software truly unhackable?

    Jump

  • A locked bootloader works with a trusted chain.

    That means:

    • There's a trusted enclave on your phone, usually inside the SoC but sometimes it's a dedicated chip. This chip has purposely very little access to it. This one contains the root keys for the encryption used on the phone.
    • The phone only boots a bootloader verified by the trusted enclave.
    • The verified bootloader verifies and only boots a verified system image.

    If everything is implemented correctly and there are no bugs that can be exploited (like e.g. on newer Switch 1 models, older ones had a bug that was exploitable), then the only thing you can do is hardware exploits.

    For that you could e.g. solder on a chip that hijacks the connection between the trusted enclave and the SoC (e.g. modchip on newer Switch 1 models) or you have to replace parts, e.g. the trusted enclave chip or the SoC (if the trusted enclave is within the SoC).

    That's usually the point where it becomes too costly to be worth it.

  • With stuff like smartphones there's literally no choice that allows you to do all smartphone stuff while also keeping control.

    Sure you can buy a Pinephone, but that's not a phone, it's just an idealistic toy.

    If you want a phone that works for 2FA, works with your bank and with your city's public transport app, then there's no libre option.

    Even a fairphone with /e/ OS isn't fully libre.

  • I've been hovering over the Lilygo T-Deck or one of its variants for a long time. I've used the T-HMI (basically a T-Deck without the keyboard) for a long time in other projects, so I'm sure I could do something with a T-Deck, but I'm just not sure if it's actually worth the purchase.

    It would be really cool to have a slick tiny device with Linux on it, but then again, how much will I really use it?

    For now, I dug out an old EEE PC 1005p and put Antix on it. I actually use that one to program while commuting.

    I also got the Fairberry keyboard for my phone, so the question is how much usability space there really is between the phone and the EEE PC.

    But I just love these sleek small devices with keyboards they used to make in the late 90s to the early 2010s.

  • Looks really sharp! Sad that stuff like that isn't made anymore.

  • Complaining about the ban does about as much good on Lemmy as it does on Reddit.

    That said, the anti-multiaccount checks are far worse on Lemmy than on Reddit.

  • Linux is one of the last bastions for the tinkerer

    Jump

  • Thank you!

    These two things didn't exist before I made them. My physiotherapy game console is currently the only one available, and in total the only one that is open source.

    There is by now another smartphone keyboard attachment, the Clicks, but there wasn't when I made my keyboard, and there still isn't another one for the Fairphone 4 and the Samsung Galaxy A54.

  • This is it.

    You don't have to tinker anymore, but if you want to, you can do so, so much more that years ago.

    I created a handheld physiotherapy game console for sick kids using a Lilygo T-HMI ESP32-S3 board for €17. Performance-wise it's somewhere between GBA and NDS. I built an OS with an app system where the users can load games from the SD card. It's got a 3D printed shell and monitors inhalation/physiotherapy using an off-the-shelf air pressure sensor. All of that was doable as a one-man hobby project within a year.

    I created a smartphone keyboard attachment. Blackberry spare keyboard, custom self-designed Arduino-compatible PCB, custom firmware, parametarized 3D printed shell. Works like any old USB keyboard and connects to the phone via USB C. I have been using this as a daily driver for the last four years.

    All of that can be done on a tight budget as hobby projects next to real work. The resources are just available. No university degree necessary.

    Tinkering much easier (and you have more abilities) than ever before!

  • Many, yes, but there are other english speaking countries too, and still the US is the only one with wide-spread spelling competitions.

  • Run!

  • I think it's only the US. In other countries spelling is a thing you are expected to be able to do it, not something you get a trophy for.

  • They are both now on the same level. Both iPhone and Android now allow sideloading of apps of "trusted" developers, so developers verified by Google/Apple.
