Ahh this OS is small enough that a university professor used it as the basis for his class assignments: write a device driver for it, or a pipe implementation, if I recall correctl…

I use the FDMQ8205. It's an old part, a little pricey, but keeps the board footprint low. It also has a sufficiently high UVLO, so it acts like regular diodes during the classifica…

Xiaomi apparently have also stopped unlocking their bootloaders, so the "workaround" was to go to an official store and ask them perform a downgrade, and before the staff can reloc…

Aahh this brings back memories. I first started out using Linux on my desktop and I found this fancy system monitor that made my desktop look cool. There's a section which displays…

Probably. Or something like the TPL5110 might actually suffice, purpose-built timer for power gating at 35nA, but only goes up to 2hr at max.

Cool, looks like text highlighting is a new addition in 2.10. There aren't any examples in the demo site of this, but can it capture the highlighted text snippets and show them in …

Well, WhatsApp backups claim they are E2E encrypted, but there’s a flow that uses their HSM for the encryption key, which still feels like some escrow system. https://engineering.f…

I have the same thoughts about the approach, and I'm actually working (on the back burner) a similar thing. It's a harman kardon "smart" speaker with a similar design where the bra…

I’m surprised HuJSON wasn’t mentioned in the list. Tailscale uses it for their config files. I did a hacky workaround by preprocessing my JSON config with regex, but found HuJSON l…

Yeah. That's what I came here to say too. Previously when their Yubikey 4's were found to be suceptible to the ROCA vulnerability [0], they issued replacements [1] for any customer…

When I initially watched the demo video, I was wondering how the devices might locate each other. I thought it was using ultra wide band (UWB) like iPhones but now I see it’s just …

I think the Luckfox Pico series is the lowest cost ARM-based board you can buy (that runs Linux) at the moment. Even the Pi Zero is $10. Prior to this, it was a board based on the …

Doesn't look like it, but the author uses the Go SSH agent library [1] which _does_ have some example code there and looks pretty straightforward, based on what was described in th…

I remember when Dell was the first to introduce [1] these Compression Attached Memory Modules in their laptops in an attempt to move away from soldered-on RAM. Glad this is now bei…

This sounds like what Roku had patented, except it injects ads when it detects that a HDMI-connected device has paused: https://www.theregister.com/2024/04/17/roku_tv_ad_patent/

It's pretty easy to apply seccomp to a process using systemd by adding SystemCallFilter= in its unit file. There's a reasonable set of permitted syscalls for general system process…

Interestingly the Pi 5 has moved most I/O like Ethernet, USB, MIPI and GPIO into a custom I/O controller chip called the RP1. It talks to the main CPU over 4-lane PCIe. They also h…

It is available on Windows too, in iTunes. You need to connect the cable once to enable it. I’m using this to sync my music and backup my iPhone.

I'm impressed to see this paragraph in the README: > System76 customers may request board schematics for their system by sending an email to firmware@system76.com with the subject …

I usually use “start .” on Windows to achieve the same.

I guess this is what Heroku was pushing for [1] when client tokens were leaked. They wanted GitHub to adopt RFC 8075 [2], that combines mutual TLS auth with the tokens, so that the…

Tom Scott did a video about this topic in 2021: https://www.youtube.com/watch?v=e0elNU0iOMY

The passkeys are only synced across Apple devices, via iCloud keychain. Trying to sign in on another device (e.g. Windows laptop, Android phone) will require scanning a QR code. Th…

Not an apples-to-apples comparison, but I just wanted to see the price positioning for this screwdriver. It goes for $69.99 [0] and Megapro ratcheting screwdrivers (which they ment…
