"Dot" in zig is a placeholder for types that can be unambigously inferred from the surrounding expression. So ".unknown" is a standin for "SomeEnum.unknown" or "SomeStruct.unknown", depending on what

The Zig maintainers clearly think that keeping up with the undocumented native API is less headache than using the documented but notoriously inelegant win32 API. This might very well be a good idea. Microsoft is not going to change a vital

Overcommit only matters if you use the system allocator. To me, the whole point of Zig's explicit allocator dependency injection design is to make it easy to not use the system allocator, but something more effective. For example ima

Do the arguments have to be strong? I do not think they need to provide any justification. If the core developers decided that they would be more happy (or less miserable) with a different service, then let them.

I miss the mention of boost::asio in this thread. At first glance this new Io interface feels not that dissimilar to it: Both are generic interfaces over an event loop/executor supporting async or blocking operations. Both ship a threa

Having a limited number of known callees is already better than a virtual function (unrestricted function pointer). A compiler in theory could devirtualize every two-possible-callee callsite into `if (function_pointer == callee1) callee1()

I think you just initialize Reader and Writer with a zero-length buffer.

Just to start some discussion about the actual API and not the breaking change aspect of it: I find the `Reader.stream(writer, limit)` and `Reader.streamRemaining(writer)` functions to be especially elegant to build a push-based data transf

Nothing fancy, I found that one can do almost anything with std::vector, a good enough hash map and a simple hand-rolled intrusive list.

The C++ code I write these days is actually pretty similar to Rust: everything is explicit, lots of strong types, very simple and clear lifetimes (arenas, pools), non-owning handles instead of pointers. The only difference in practice is th

For me, someone from outside the Anglosphere, the British Empire is a distant and unfamiliar concept. I am always bothered by characters in historical fiction speaking with a British accent just to make an impression of ancientness. The ant

One downside of this approach is that the tested code itself has to be modified to accomodate the testing code. I think the same could be achieved by launching two threads and single stepping them with ptrace to "randomly" interle

I would absolutely not recommend auto-formatting a legacy codebase. In my experience large C++ projects tend to have not only code generation scripts (python/perl/whatever) but also scripts that parse the code (usually to gather d

The Internet Speculative Fiction Database is a great resource for publication details of fiction stories. Here is the entry for The Star: https://www.isfdb.org/cgi-bin/title.cgi?40913

I was about to comment that the correct plural form of nova is novae, but it looks like dictionaries say that both novae and novas are correct. The irregular case does seem to predominate according to google ngram viewer.

Despite absolutely loving chess as a child, I never studied it professionally, and I did not even play a single game after primary school. A couple of years ago I stumbled upon a chess video recommendation here on Hacker News. It was the 27

In Calibre (the ebook management software) there are two fields: "author name" and "author sort name", both free-form text. The latter serves as the sort key when the books are ordered by author. I have found this soluti

The sizeof(variant) example is wrong. An extra byte is needed to store the discriminator value, which in practice results in 8 extra bytes for these particular types because of alignment. https://godbolt.org/z/vno3v9rPK

In Bash (not every shell supports this) functions can be exported, which enables this nice pattern with xargs: myfunc() { printf " %s" "I got these arguments:" "$@" $'\n' } expor

This wikipedia article is not very accurate. In Hungary "informatika" is usually used only for primary/secondary school subjects covering every-day IT tasks like document editing, typing, or sending email. The most commonly u

Your comment reminded me of a clever and well-written short story called "Understand" by Ted Chiang. > We could fuzz it and see if we can crash a brain. Sadly, this we already know. Torture, fear, depression, regret; we have a
