Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

I hate almost all software
That's awesome! I'm working on something that sounds similar. https://github.com/cons-cat/libcat
I'd love to see your work if you're willing to share it here!

Why Janet?
This runtime size bothers me a lot. So much that I've been working on a new runtime for C++ that breaks POSIX compatibility to keep binaries as small as they can be. The hello world with LTO is 330ish bytes right now, and I think that can get smaller. https://github.com/Cons-Cat/libCat

std::initializer_list in C++ 1/2 - Internals and Use Cases
I'm working on a library that replaces both C++ and C/POSIX standard libraries (https://github.com/Cons-Cat/libCat), but even then I need to define a few std:: namespace symbols for some features. In the case of std::initializer_list, my answer is just don't use that feature, because you don't really need it.

Chromium accepting Rust in a clear move to copy what Mozilla have done, replace C++ source code
It's worse in the standard library than it has to be. When I refactored my traits to minimize template instantiations and lean on concepts as much as possible, I measured over 30% improvement to clean build compile times. It's not possible for the standard to do this, because it would subtly change the API. For instance, you can't instantiate or take the address of a concept, but you can for a type-trait class. No reason you'd want to do that, but you can, so they can't "break" the standard library by optimizing this.

C++'s smaller cleaner language
This doesn't have to be true. Over the past year I've made progress towards demonstrating how even non-freestanding C++ can be written without any C or C++ standard library headers or DLLs (with large benefits). There are a few names which the compilers require to be in the std:: namespace, though, but they're very special features like source_location and construct_at with semantics that can't be expressed otherwise.

C++ is essentially unusable without incurring undefined behavior because of it's failure to handle type punning.
This bit cast has no overhead in debug mode, and is a little bit more generally useful than std::bit_cast(), but cannot be constant evaluated. https://github.com/Cons-Cat/libCat/blob/main/src/libraries/utility/implementations/bit_cast.tpp

Is bloat in std::unexpected expected?
It isn't that hard to put a predicate into a type. We have lambdas in an unevaluated context, CTAD, and templated type aliases. https://github.com/Cons-Cat/libCat/blob/main/src/libraries/scaredy/cat/scaredy https://github.com/Cons-Cat/libCat/blob/main/src/global_includes.hpp#L70 https://github.com/Cons-Cat/libCat/blob/main/src/libraries/linux/cat/linux#L289 You do it like this.
-
CamelCase for C++?
But suppose that you have code with no standard library calls at all. Would it still make sense to choose this naming convention? This is actually possible, with a few special exceptions. GCC requires that an implementation of std::source_location has very particular class member names, GCC assigns special semantics to a few function names including std::construct_at and std::move (people seem to know it's inlined, but did you know std::move is required for move-related warnings?), and most intrusively of all, a promise_type must be snake_case. Other names can be worked around by using them into a different namespace with a different letter-case, but promise_type seems unavoidable.

Competitive programmer using c++, but absolutely ignorant of other things the language can do here. What else can c++ do?
I use C++ for a low-level Linux runtime. Other people are using it for operating systems like SerenityOS and Zircon/Fuschia. People also use C++ for making more compilers like GCC and LLVM.

I use NixOS for my home-server, and you should too!
As we covered in my last post, NixOS is a amazing Linux distribution for creating stable and declared environments. Now while this is amazing for a desktop setup, it is also perfect for a home-server or home-lab.

Tvix β A New Implementation of Nix
(Nix itself is slowly chugging along with Windows via MinGW - https://discourse.nixos.org/t/nix-on-windows/1113/108 and https://github.com/NixOS/nix/issues/1320 , for example.)

Colima k8s nix setup
Nix is a cross-platform package manager. It uses the nix programming language. Nix and NixOs are often used in the same context, but while the first is a package manager, the latter is a linux distribution based on nix.

NixOs - Your portable dev enviroment
Today I want to talk to you about Nixos. What is it? Nixos is a declarative and reproducible OS, partly taking the words used on their own page. What does that mean?

Nix β A One Pager
Software developers often want to customize:
1. their home environments: for packages (some reach for brew on MacOS) and configurations (dotfiles, and some reach for stow).
2. their development shells: for build dependencies (compilers, SDKs, libraries), tools (LSP, linters, formatters, debuggers), and services (runtime, database). Some reach for devcontainers here.
3. or even their operating systems: for development, for CI, for deployment, or for personal use.
Nix provision all of the above in the same language, with Nixpkgs, NixOS, home-manager, and devShells such as https://devenv.sh/. What's more, Nix is (https://nixos.org/):
- reproducible: what works on your dev machine also works in CI in prod,
- declarative: you version control and review your configurations and infrastructure as code, at a reasonable level of abstraction,
- reliable: all changes are atomic with easy roll back.

Tools for Linux Distro Hoppers
Hopping from one distro to another with a different package manager might require some time to adapt. Using a package manager that can be installed on most distro is one way to help you get to work faster. Flatpak is one of them; other alternative are Snap, Nix or Homebrew. Flatpak is a good starter, and if you have a bunch of free time, I suggest trying Nix.

Ask HN: Could Nix make crypto mining more efficient?
- it reduces bloat, because you can generate an environment or OS image with only the software needed to run a specific program or service
My guess is that a big efficiency gain would come from the second point, because you don't waste CPU on code that you don't use.
Does this make sense? Has anyone explored this?

Go + Hypermedia - A Learning Journey (Part 1)
1) Setting up the development environment - I currently use devcontainers for most things, but may also dig into nix -> isolated, portable, repeatable development environment 2) Exploring Echo - understand routing, requests, response, etc. 3) Incorporate Templ - integration with Echo, template composition, etc. 4) Integrating TailwindCSS - config for use with Echo/Templ, development cycle, deployment, etc. 5) Add in HTMX - endpoints, template structure, concepts, etc. 6) hyperscript for interactivity - client side interactivity
