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.

Benchmarking Java against Rust #3
You're looking at the non-optimized version. If you read the blog post you would've seen your suggestions had already been implemented.
- Help me find bottlenecks in this benchmark. I ported the Common Lisp solution to Zig and the Zig version is much slower?!

Optimising Common Lisp to try and beat Java and Rust on phone encoding 2/2
> it’s using Unicode-aware string stuff
Rust uses UTF-8 internally for Strings, so it's very efficient to parse a file into a String, then using slices to go through it... this is probably the best you can get as parsing ASCII input as UTF-8 is very efficient (the 0-bit is always zero in ASCII, the unicode decoder only needs to check that's the case for every byte, so it's not some kind of complicated computation it's doing to decode)...
If you use bytes for everything, you will make the whole code much harder to follow and it still won't run faster.

Learning Common Lisp to beat Java and Rust on a phone encoding problem
This is a pretty introductory CL article, mostly a commentary on Norvig's solution to the problem. Still, I learned about the #. readmacro from it. The conclusion: "[The Lisp implementation] was the fastest implementation for all input sizes except the largest one, where it performed just slightly worse than my best Java implementation." GH repo at https://github.com/renatoathaydes/prechelt-phone-number-enco.... Sounds like he was mostly measuring the performance of the SBCL bignum implementation.

How to write fast Rust code
OMG you're right... I'm the author, and the reason it was allocating in my original code was that I was calling the operators on a reference to n. See https://github.com/renatoathaydes/prechelt-phone-number-encoding/commit/6683dc10cc4fb380abead632b87d94e8937f8377

How to write slow Rust code - Part 2 (a deeper look into what really made my code slow)
This commit show how to improve that: https://github.com/renatoathaydes/prechelt-phone-number-encoding/commit/561a7307b5574bd6fd7b8cc638abf6f29884b6ca

My battle to beat Common Lisp and Java (in Rust) on a phone number encoding problem. Sequel to "Revisiting Prechelt's Paper…". (and they didn't even optimize the Lisp code)

How to write really slow Rust code
I get the need to want to obsessively optimize the code. There's nothing more fun than to optimize something simple, artificial, and narrowly-defined. But y'all need to take a deep breath, step back, and realize that one blog post isn't going to suddenly define the language (nor should it personally define you).

Zed – A high-performance, multiplayer code editor written in Rust. Now in public beta
Sounds like what you want is emacs, but preconfigured. In that case, have you tried Doom Emacs, Spacemacs or any of the myriad of others like those?

How to specify formatter for LSP mode?
`;; Needed to add javascript-eslint to the the next-checker after lsp so that it would actually load, as that wasn’t happening by deafult ;; also needed to runit after the lsp-afer-initalize-hook because otherwise ‘lsp wasn’t a valid checker (add-hook ‘lsp-after-initialize-hook (lambda () (flycheck-add-next-checker ‘lsp ‘javascript-eslint))) ;; https://github.com/hlissner/doom-emacs/issues/1530 ;; Potential alternative to the above ;; (after!

Emacs for Professionals
The performance lag of Spacemacs was addressed by Doom Emacs ( https://github.com/hlissner/doom-emacs ). Have you tried Doom Emacs by any chance. After syncing everything, the performance is stellar in my opinion.

Please help me in translating my vimrc to emacs equivalents.
but I just realized, you're probably better off using doom emacs. The defaults are sane, customizations are almost always optional and the community's really active/helpful. (Disclaimer: I'm a doom emacs user with ~2k lines of config)

Just discovered emacs as a long term vim user and it's incredible
While Doom is more opinionated, it's not too difficult make Emacs your own, most of the choices are optimized anyway. Currently the head of Spacemacs devs is not active on the project anymore. Also I don't think it's hard to upstream code to Doom, as long as the code is thoroughly written, take a similar example on both sides: the introduction of a completion engine as layer/module (same packages are installed): - https://github.com/syl20bnr/spacemacs/pull/14901: 23 comments, 7 participants - https://github.com/hlissner/doom-emacs/pull/4664: 576 comments, 20 participants

What would you consider a modern lisp workflow/toolchain?
Also Doom emacs has one. https://github.com/hlissner/doom-emacs https://github.com/hlissner/doom-emacs/tree/master/modules/lang/common-lisp

Should I learn vim in 2022?
Nowadays, I use https://github.com/hlissner/doom-emacs with WSL2 but only for org-mode. For code, I have either Sublime Text or VS Code.
