It's that day when a one-liner "add" -> "sub" fix asks for a commit message the size of a blog post: github.com/rtfb/riscv-hobby-…

Turns out, the solution was both obvious and not. The obvious part: add-symbol-file. It can be specified with an offset, but a negative offset has to be two's complement: add-symbol-file out/os_virt -o 0xffffffff80000000 xitter.gq/rtfb/status/1761335870…

Hive mind, is there a way to rewrite symbol addresses in DWARF? I thoroughly fail to find even a decent library to write the symbols (as opposed to just reading them). Modifying them within gdb after loading would also suit me, but can't find that either.

Here's the use case: I run things in qemu-system and I have a function foo(), which lands at address 0x8000abcd. But I only ever execute that function with virtual addressing enabled, at address 0xabcd.

Timer interrupt handling in M+S modes on RISC-V is confusing. Here are some of my notes that others might find useful: github.com/rtfb/riscv-hobby-…

And a polite response to that is "no no no, this is a tobacconist's".

Andrew took a very reasonable path of lesser resistance. More people should consider that instead of wasting 15 years learning a subset of C++.

I cannot stop thinking about this. Andrew created Zig and ~15 years ago asked on SO how to open a file in C++

Glad to announce that after the meeting I hosted with @RTErdogan & @SwedishPM, President Erdogan has agreed to forward #Sweden's accession protocol to the Grand National Assembly ASAP & ensure ratification. This is an historic step which makes all #NATO Allies stronger & safer.

Hey, @SbudnicS there's a sbudnic.space/repository section on the website, but it's empty. Are there plans to opensource some of the engineering details?

Same with naming an IDE after an astronomical phenomenon where one celestial body obscures the other by blocking the line of sight or illumination.

Naming a framework after Kafka, at least to me, adds some signals about the usability and the trials I'd have to go through to use it...

Survey: If there's on thing we could improve, what would it be? Me: No mandatory fields in survey forms.

@elonmusk @SpaceX is there a reason not to do a grasshopper-like prelaunch "dynamic fire" tests now that landing has been proven to work?
Golang protip: never forget to PipeWriter.Close(), esp if wrapped in smth like gzip.Writer (close both). Or your io.Copy will never end.

I hammered together a POC for godoctest (github.com/rtfb/godoctest), a tool a-la Python's doctest. Thoughts? Comments? Prior art?
