This release also fixes runtime.findnull() to be compatible with MTE on Android ([1] and [2]). This was the only thing preventing MTE from being enabled for apps that use gomobile …

It looks like all the old files are still hosted on the server. You can just replace the version number in the download links with one of the tags from https://git.zx2c4.com/wiregu…

This article isn't about the installation of regular apps. The "sideloading" it's referring to is the option to use the "adb sideload " command when booted into recovery mode to in…

It's probably worth pointing out that the online process is one time and it installs a token that permanently lets the setting be toggled offline afterwards. This persists across f…

NFC payments via Google Wallet running on my Pixel Watch 3 connected to a phone running GrapheneOS works just fine. I use this regularly. (It doesn't require Google Wallet to be in…

I wrote https://github.com/chenxiaolong/MSD for exactly that. It's a small wrapper around the Linux kernel's mass storage emulation support (CONFIG_USB_CONFIGFS_MASS_STORAGE). It c…

Yeah, my GitHub Actions workflows don't do much more than `cargo build --release && cargo test --release`. I don't use any of the fancy features that would lock me in. It's really …

For me, I begrudgingly use GitHub for my personal projects because GitHub Actions is free. If I move elsewhere, I'll have to stop providing precompiled binaries for OS's that I can…

There shouldn't be any side effects other than rendering Play Protect inert. No other AOSP component relies on this setting.

If this is enforced via Play Protect, then the whole mechanism can likely be disabled with: adb shell settings put global package_verifier_user_consent -1 This does not require roo…

I'm curious how the check is implemented in Google Play Services. If it's based on the package manager's initiatingPackageName field, it should be trivial to bypass on rooted devic…

This should work with any arbitrary filename: latest=$(printf '%s\0' | sort -zrV | head -zn1) or with long args: latest=$(printf '%s\0' | sort --zero-terminated --reverse --version…

I'd recommend giving openconnect a try. It was originally meant for Cisco VPNs, but has also supported GlobalProtect for a while now. It integrates with the NetworkManager GUI if y…

Visual voicemail is when the dialer app on your phone can show the list of voicemails similar to how you would see your email inbox. You can directly play the voicemail messages an…

One area where the distinction between PIDs and TGIDs matters a whole lot is for using ptrace on processes that call execve() (eg. for something like `strace -f`). In can be pretty…

No worries! Thanks for the hint about the date -- I didn't know that was a function in the equation. Changing the date back to 2023 actually allowed the 19190301 code (had a typo i…

Any chance you happen to know the latest code to get into the hidden menu on the EV6? Used to be 19190307, though it was changed in the 231215 infotainment firmware update.

It looks like it is packaged in the official Fedora repos: https://packages.fedoraproject.org/pkgs/foot/foot/

> but explicitly tells users not to do that They set the vbmeta header flags field to 0x3, which effectively turns off all of AVB (Android Verified Boot). I'm guessing they do this…

Yup, Bluetooth devices can report the latency via AVDTP 1.3 Delay Reporting. If I remember correctly from the last time I looked at this, the media framework in OS's tend to expose…

I really like this program's UI. I assume it's built on the textual library? Unfortunately, my main use case for a hex editor is editing very large files (firmware images, disk ima…

LinkSheet [1] can do that. It's a small app that you set as the default browser and shows a prompt when you open a link to allow you to choose what to do (eg. open in browser, open…

Related submission from earlier today: https://news.ycombinator.com/item?id=38125379 (Though this article also explains how to enable MTE for user apps and verify that it's enabled…

Per [1], I've also enabled MTE for user applications via the `persist.arm64.memtag.app_default` property. So far, the only crashes I've seen have been in apps that use cgo (eg. syn…

Wonderful tool! I started using it since 0.6 because sbsigntools and pesign both choked on some EFI executables I had, but sbctl's go-uefi parser did not. It also seems to handle e…
