If I understood this comment correctly, this approach wouldn't work with a single possible tombstone value. If the table has, for instance, a tophashes array that looks something l…

Yes! The JSON library I wrote for the Zephyr RTOS does this. Say, for instance, you have the following struct: struct SomeStruct { char *some_string; int some_number; }; You would …

The Linux man page ( https://man7.org/linux/man-pages/man3/atoi.3.html#VERSIONS ) says that POSIX.1 leaves it unspecified. As you found out, it's really something that should be av…

One thing to note, too, is that `atoi()` should be avoided as much as possible. On error (parse error, overflow, etc), it has an unspecified return value (!), although most libcs w…

Programs running under any Valgrind tool will be executed using a CPU emulator, making it quite a bit slower than, say, running the instrumented binaries as required by sanitizers;…

Go has had its own version of msan and asan for years at this point.

I wrote the Lwan web server, which similarly to Go, has its own scheduler and makes use of stackful coroutines. I have spent quite a bit of time Valgrinding it after adding the nec…

I recently wrote one, in C, using tail calls to implement dispatch with CPS: https://tia.mat.br/posts/2025/08/30/forth-haiku.html It's already pretty efficient but I'm working on i…

I recently implemented a Forth, compatible with the Forth Haiku dialect used by https://forthsalon.appspot.com/ -- it uses a tail call/continuation-passing dispatching method, and …

There's another small one in Campinas, near the Nipo-Brazilian Institute: https://viajantesemfim.com.br/rua-camargo-paes-um-pedacinho-... (or on GMaps: https://maps.app.goo.gl/P17s…

Thank you!

Reminds me of this sample from the Lwan project: https://time.lwan.ws/blocks -- where the clock is rendered on the server, and new frames are sent to the client using chunked encod…

Details are hazy as this was a long time ago, but at some point you could make parts of messages not render in Outlook and Outlook Express by writing "begin something" (two spaces …

This is roughly what my JSON parser does. It does type-checking, albeit without using JSON-schema, but an object descriptor that you have to define to parse and generate JSON. It's…

Yes, that's the library! It's something I've been slow cooking for over 10 years at this point. :)

It's collected after 15min, give or take. The hash isn't random, it's the SHA-1 hash of the base64-encoded data, so it's predictable -- if something keeps accessing the base-64 enc…

On the client. Data is already stored in the ZIP file deflated, so I can just send whatever is inside the ZIP file back to the client if they accept that encoding (which is pretty …

I love this!

Then it would require JavaScript and wouldn't be a nice demonstration for my web server library. :)

Oh, this is a cool experiment!

That's why we can't have nice things. :(

Files are not decompressed in the server: it sends the unmodified deflate stream back to the user.
