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.

Let's write a compiler, part 5: A code generator
Depends on the complexity of your queries, but if you have a narrow subset that you're interested in, implementing a recursive descent parser for just those parts of the syntax that fits your problem like a glove could be a better solution.

Let's write a compiler, part 3: A parser
What few seem to realize is that it's perfectly possible to abstract out some of the work and create an extensible foundation for manual parsers.
Since it's all regular code, you can use the full power of the host language to deal with the problem.

Multi-Database Support in DuckDB
We have some of this functionality in Presto (https://github.com/prestodb/presto), but it takes fair bit of work to implement it for all the different backends.

Rust std:fs slower than Python
Note that glibc has a similar problem in multithreaded contexts. It strands unused memory in thread-local pools, which grows your memory usage over time like a memory leak. We got lower memory usage that didn't grow over time by switching to jemalloc.
Example of this: https://github.com/prestodb/presto/issues/8993

Cheat sheet for quotes usage?
I look at the grammar. Here is preto's grammar which is mostly similar to other sql engines: https://github.com/prestodb/presto/blob/master/presto-parser/src/main/antlr4/com/facebook/presto/sql/parser/SqlBase.g4

What are y'all learning right now?
more specifically, recently started learning about Presto [paper], and have been diving deeper into [source] code.
