I sometimes use abbreviations like wd/ht. Should be understood with surrounding context.

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 correctly. I thought it was pretty genius at the time, and it was ce

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 classification phase and you don't need to factor those in t

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 relock the bootloader, grab the phone and run: https:&

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 the link details page? That would help me recall quickl

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.fb.com/2021/09/10/security&#x2

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 brains are on a separate daughterboard and

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 later. https://github.com/tailscale/hujs

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 customers who had affected devices. I had a few of those d

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 GPS. I’m not sure how many of these events are indoors vs ou

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 Allwinner F1C100, but I don't think anyone made and sol

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 the post. [1] https://pkg.go.dev/golang.o

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 being more widely adopted and standardized. [1] https:/&#

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 processes, aptly called `@system-service`, but you can tw

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 have a custom PMIC (Dialog DA9091) with a built-in

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 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 tokens can only be used by authorized clients, not just any

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. The devices then establish a secure channel using FIDO caBLE v

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 mentioned in their video) goes from ~$50 to $59.99, depending on

This is based on the open standards WebAuthn and FIDO2, where the credentials (“passkeys”) are synced via iCloud Keychain. Currently you need remember to register at least 2 security keys, in case one is lost/misplaced. The syncing of

It depends on how the TPM is being used by the OS and its apps. If it’s purely being used for the crypto key storage and crypto operations, then you can probably use something like the MS reference implementation [0]. If the OS requires att
