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.

We have used too many levels of abstractions and now the future looks bleak
Agreed!
It reminds me of:
https://github.com/alex/what-happens-when
and how many of today’s CS-degree holders would barely understand any of it. As someone who has also “grown up with all the technology”, I’ve learned and experienced all that. But as a percentage of “software engineers”, there’s fewer and fewer that do every day.

I just blew my interview!
There is a pretty comprehensive answer to number 2 here

Are you skeptical about candidates that call themselves a "10x engineer"?
Ask them to describe what happens when you visit a website and grill them on every layer of abstraction, every implementation detail.

You and me Anon, you and me
This is a classic interview question and it basically means "How does internet work?" It is great because it allows to check how many levels of understanding it a developer has. The answer may be quite lengthy, for example: https://github.com/alex/what-happens-when

I have a question about subdomains and their DNS resolution

The Top 10 GitHub Repositories Making Waves 🌊📊
Papers We Love (PWL) is a community built around reading, discussing and learning more about academic computer science papers. This repository serves as a directory of some of the best papers the community can find, bringing together documents scattered across the web. You can also visit the Papers We Love site for more info.

We have used too many levels of abstractions and now the future looks bleak
You might find the paper Out of the Tar Pit interesting if you haven't already read it: https://github.com/papers-we-love/papers-we-love/blob/main/d...
The ideas and approaches you talk about evoked some of the concepts from that paper for me. It talks a lot about separating accidental complexity and infrastructure so you can focus only on what is essential to define your solutions.

John McCarthy’s collection of numerical facts for use in elisp programs
Sure he was expecting a practical language and was designing one. Lisp was from day zero a project to implement a real programming language for a computer.
Earlier he experimented with IPL and also list processing programming on Fortran. The plan was to implement a Lisp compiler. At first the Lisp code McCarthy was experimenting with, was manually translated to machine code.
Then came up the idea to use EVAL as a base for an interpreter, which was implemented by manually translating the Lisp code to machine language. Around 1962 then a compiler followed.

Python: Just Write SQL
I'm in a 4th camp: we should be writing our applications against a relational data model and _not_ marshaling query results into and out of Objects at all.

Ask HN: Incremental View Maintenance for SQLite?
The short ask: Anyone know of any projects that bring incremental view maintenance to SQLite?
The why:
Applications are usually read heavy. It is a sad state of affairs that, for these kinds of apps, we don't put more work on the write path to allow reads to benefit.
Would the whole No-SQL movement ever even have been a thing if relational databases had great support for materialized views that updated incrementally? I'd like to think not.
And more context:
I'm working to push the state of "functional relational programming" [1], [2] further forward. Materialized views with incremental updates are key to this. Bringing them to SQLite so they can be leveraged one the frontend would solve this whole quagmire of "state management libraries." I've been solving the data-sync problem in SQLite (https://vlcn.io/) and this piece is one of the next logical steps.
If nobody knows of an existing solution, would love to collaborate with someone on creating it.

Good papers for high school students?
Here is a great Repo on GitHub named paers-we-love. You will surely find some great papers there and also some good other resources. Hope this helps.

I think Zig is hard but worth it
However, f and g are interchangeable anywhere else (this is not actually true because their addresses can be obtained and compared; showing that a C-like language retains its referential transparency despite the existence of so-called l-values was the point of what I think is the first paper to introduce the notion referential transparency to the study of programming languages: https://github.com/papers-we-love/papers-we-love/blob/main/l...)
