I plugged my iPhone 16 into my usb-C docking station the other day to charge it and was pretty surprised to discover it just started mirroring my phone screen. Keyboard worked too!…

Put a script in /etc/systemd/system-generators/ that does something like if grep "logging = syslog" /etc/stupid-service/stupid-service.conf >/dev/null; then printf "[Unit]\nAfter=r…

Yeah parsing config files with regular expressions that may or may not properly handle quoting or line continuations etc is… not a great idea in my opinion. But of course in this p…

Something like the stm32mp2 series of MCUs can run Linux and act as a PCIe endpoint you can control from a kernel module on the MCU. So you can program an arbitrary PCIe device tha…

Was expecting some real unproductive and entitled whining based on the title, but was pleasantly surprised - someone actually investigating and debugging their wayland issues rathe…

Hm. I found this (that memory must be stable wherever a SEH exception could be thrown) surprising, because I thought the unwind information generated by the compiler should be able…

I have no idea whether the text was generated from an LLM, but “slop” it absolutely is not - it’s clearly a very logically ordered walkthrough about a very thorough debugging proce…

That’s exactly what it was. He discovered the customer was using a version of ffi that had this “use-after-free” (ish) bug, but the question “is this actually what my customer was …

I personally know and have (tangentially) worked with the guy and none of what you’ve said is true. > Look at his CV. Tiny (but impactful) features ///building on existing infrastr…

Thanks for clarifying, and implementing this essential feature!

Question: what actually reads /etc/pooper to configure the character? I can’t work out how that file’s contents ends up as module parameters and I’d love to know!

I don’t know what you’re basing this on. Good psychiatrists absolutely “call themselves doctors” and definitely seek to exclude or treat organic causes of psychiatric symptoms. All…

/proc/PID/root is a view of that process’s mount namespace. Also you can use nsenter(8) to run a command (or even a shell) under another process’s mount, pid, network, etc namespac…

This is in fact exactly what Ruby’s Fibers and the async fiber-scheduler gem do

I don't work on YJIT but I _think_ i know the (or maybe an) answer to this. The code for a JIT'd ruby method isn't contiguous in one location in memory. When a ruby method is first…

This doesn’t really change your conclusion, but I think that’s the wrong file. This is the real doas afaict: https://github.com/openbsd/src/blob/master/usr.bin/doas/doas... Still j…

This is essentially what systemd-resolved with the nss-resolve NSS module is right? It’s possible to use /etc/nsswitch.conf to entirely disable the built-in DNS resolution in glibc…

I winced when I saw the phrase "multithreaded fork" but then I realised this is the _other_ kind of fork, not the fork(2) syscall.

The problem is that with perf the stack trace is collected by the kernel (when the interrupt from the performance counters fires), and the kernel doesn’t implement dwarf unwinding …

Hope these people never send any emails, I hear they can be searched for a long time too.
