I guess it took a bit longer to get it adopted within Go because of some additional challenges: https://go.dev/blog/swisstable#go-challenges

Interesting that it doesn’t use the same open source license as Vorbis/Opus itself. Otherwise improvements like these could be upstreamed?

If I understand that correctly, it means your app always creates traces, and Grafana Cloud is responsible for sampling/aggregating. That may be prohibitively expensive in terms of CPU/network load. What I’m suggesting is that your

What always puzzles me about OpenTelemetry is that tracing, metrics and logs are all designed independently. I wish there was a way I could just annotate my code base once, and let the ultimate decision to expose something as a metric/

Go is often thought of as a successor of C. C doesn't have methods, only global functions. From my perspective, Go added methods primarily so that you can use them in combination with interfaces. Given that interfaces don't suppor

Yeah, that Sudoku puzzle has multiple valid solutions, whereas the page only seems to accept a single one.

It looks like the code of the course was 2WC16. Unfortunately the course material no longer seems to be available online.

I still remember following Andries’s “Linux kernel hacker’s hut” course he taught at the Eindhoven University of Technology (TU/e) back in 2010. Every week we’d get an assignment where we had to write exploits for commonly occurring se

> If sizes are unsigned, like in C, C++, Rust and Zig – then it follows that anything involving indexing into data will need to either be all unsigned or require casts. I don’t really get this claim. Indexing should just look up the elem

You can always use a divide and conquer strategy to compute the chunks. Chunk both halves of the file independently. Once that’s done, you redo the chunking around the midpoint of the file forward, until it starts to match the chunks obtain

It depends on the architecture. On ARM64, SHA-256 tends to be faster than BLAKE3. The reasons being that most modern ARM64 CPUs have native SHA-256 instructions, and lack an equivalent of AVX-512. Furthermore, if your input files are large

That’s great! People who do that are often inconsiderate of how it affect others. First of all, it generates unnecessary noise, which is annoying for neighbors who are still trying to sleep. Pedestrians/cyclists also need to breathe th

I don’t understand why I would need to care about this. Can’t my operating system and/or pthread library sort this out by itself?

Yeah, that's true. Having some kind of chunking algorithm that's content/file format aware could make it work even better. For example, it makes a lot of sense to chunk source files at function/scope boundaries. In my ca

In my case I observed a ~2% reduction in data storage when attempting to store and deduplicate various versions of the Linux kernel source tree (see link above). But that also includes the space needed to store the original version. If we t

Yeah, GEAR hashing is simple enough that I haven't considered using anything else. Regarding the RNG used to seed the GEAR table: I don't think it actually makes that much of a difference. You only use it once to generate 2 KB of

I’ve also been doing lots of experimenting with Content Defined Chunking since last year (for https://bonanza.build/ ). One of the things I discovered is that the most commonly used algorithm FastCDC (also used by this proje

So 19494 is the largest? That's far lower than I expected. There's nobody out there that has put a date in a version number (e.g., 20250915)?

Exactly! At the same time you also don't want to call into the kernel's internal malloc() whenever a thread ends up blocking on a lock to allocate the data structures that are needed to keep track of queues of blocked threads for

That's not entirely true: with CBOR you can add custom data types through custom tags. A central registry of them is here: https://www.iana.org/assignments/cbor-tags/cbor-tags.xhtml This is, for example, used

If only there was a variant of execve() / posix_spawn() that simply took a literal array of which file descriptors would need to be present in the new process. So that you can say: int subprocess_stdin = open("/dev&#x2F

Same in Dutch. “Oproepen” means “to summon”. We would use “aanroepen”.
