Quite often I find myself landing on gcc’s attributes documentation page. Not
sure how that happens but this is always a gold mine. I’ve recently discovered
__attribute__((cleanup(func))), which allows attaching functions to
variables. These functions are executed when the variable goes out of scope.
Sounds familiar?
I’ve recently discovered a paper1 about Robin Hood hashing and decided
to perform some simple experiments and check how a trivial, custom implementation
of a hash table employing this algorithm stacks against unordered_map.
PEP 723 standardises new inline metadata
for scripts. It’s most useful when writing stand-alone scripts as the
dependencies can be managed within the script itself without having to setup a
complete project and create pyproject.toml file.
Have you ever used member functions with reference qualifiers? This a feature introduced in C++11, being an essential part of move semantics.
The topic of dependencies management is coming back and again. nix and
nixpkgs being a rich repository, provides a convenient way to manage both
project dependencies and related tooling in a reproducible way. This is
something I’m finding more and more useful as a fundamental development tool.
nix is quite complex and some exploration is needed to wrap your head around
it. In this post, I’m going through most basic use cases as well as describe
some basics of nix language itself - mainly for my own reference but
hopefully useful to others as well.
I bet that whenever you think of a simple database, you think of sqlite. There’s nothing wrong with that but the filesystem itself can be an even simpler substitute.
The more opportunity I have to work with lua, the bigger fan of it I become. It’s a great, well designed language which is very easy to embed.
I’ve been recently working on a small utility for myself. There’s always a problem of handling configuration in such projects. Usually, I’m going for a simple json or yaml or toml file which acts purely as key-value store but this time around I wanted to try something different.
