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/O is no longer the bottleneck
Note: Just concatenating the bibles keeps your hash map artificially small...which matters because as you correctly note the big deal is if you can fit the histogram in the L2 cache as noted elsewhere and this really matters if you go parallel where N CPUsL2 caches can speed things up a lot -- until* your histograms blow out CPU-private L2 cache sizes. https://github.com/c-blake/adix/blob/master/tests/wf.nim (or a port to your favorite lang) might make it easy to play with these ideas.

A Cost Model for Nim
which is notably logarithmic - not unlike a B-Tree.
When these expectations are exceeded you can at least detect a DoS attack. If you wait until such are seen, you can activate a "more random" mitigation on the fly at about the same cost as "the next resize/re-org/whatnot".
All you need to do is instrument your search to track the depth. There is some example such strategy in Nim at https://github.com/c-blake/adix for simple Robin-Hood Linear Probed tables.

Performance comparison: counting words in Python, Go, C++, C, Awk, Forth, Rust
Knuth-McIlroy comes up a lot. Previous discussion [1]. For this example I can make a Nim program run almost exactly the same speed as `wc -w`, yet the optimized C program runs 1.2x faster not 3.34x slower - a whopping 4x discrepancy - much bigger than many of the ratios in the table. So, people should be very cautious about conclusions from any of this.

Nitter (Twitter front end) is working again
The frontend uses Karax, which is my favorite frontend/SPA library. It is an absolute joy to use, even if it's a bit rough around the edges.

I learned 7 programming languages so you don't have to
I have used Nim for personal projects for 6 years now and it continues to surprise me on how well versed it is for many problem domains. I am fond of it's SPA framework, karax https://github.com/karaxnim/karax for which I wrote a translation utility https://github.com/nim-lang-cn/html2karax Latest Nimv2 release candidate has improved in the ergonomics and syntax that affect compilation to js, so I was able to cleanup my webapp's code to be less verbose. On GPU programming there has been a few projects that touch GPU programming, most notably https://github.com/treeform/shady

Web apps in pure Python.
And it's present not only in Python but in other languages as well. Check for example https://github.com/karaxnim/karax - I don't know why people would want to hide all of their HTML in Python/whatever language. Then limit their ability to script and style it in one way or another.

A Cost Model for Nim
> the real killer feature to me is the javascript target
Agree, this is amazing because you can share code and data structures between front and backend (for example: https://github.com/karaxnim/karax).
Also, it's really nice having high level stuff like metaprogramming and static typing spanning both targets. Things like reading a spec file and generating statically checked APIs for server/client is straightforward, which opens up a lot of possibilities.

How to use JS to make a front end
I recommend you to take a look at Karax. It's a front-end framework for Nim that can compile to regular JavaScript. If you want to know how to use it with a webserver, Joker is a good example. With the Joker config, all of the compiled .js files land in /public/views, where you can take a look at them. But keep in mind that the JS that Nim produces is often rather cumbersome and hundreds of lines long, even if it's just a simple program.
