pg_worker_pool: extension creating a pool of background workers
github.com GitHub - serpent7776/pg_worker_pool: Postgres extension creating a pool of background workers
Postgres extension creating a pool of background workers - serpent7776/pg_worker_pool
I'm doing an extension that creates a pool of named background workers. Happy to hear any feedback on this.
undefined
CREATE EXTENSION pg_worker_pool;
CALL worker_pool.submit('foo', 'create index myindex_1 on my_big_table (id)');
CALL worker_pool.submit('foo', 'create index myindex_1 on my_big_table (name)');
CALL worker_pool.submit('bar', 'create index otherindex_2 on other_big_table (author)');
CALL worker_pool.submit('bar', 'create index otherindex_2 on other_big_table (title)');
This will start two background workers, foo and bar. foo will create an indices on table my_big_table and bar on table other_big_table. foo and bar will run independently of each other, but all indices submitted to the same worker will be created in order.
dev.to Comparing C++ range libraries for filter+reverse case with non-trivial lambda
EDIT 2024-06-04: Fixed issue with flux implementation, thanks to tcbrindle for catching this. EDIT...
I wrote a blog post comparing several range libraries for a case that is doing filter with non-trivial lambda and then reverse.
I added bun and deno. Updated results are on the github page. Deno is similar to node, bun takes much less time.

A blog post shows an example usage of hyperfine CLI tool to measure and plot time of startup and shutdown of several code interpreters.
Programming Language Awareness Centre
A Programming Language Learner's Resource. Contains descriptions of many ineresting programming languages, like APL, ABC, FP, Factor with examples and further links.
It should be easy to edit the existing code to add support for i18n, but there's probably no way to make in generic (except for macros).
Yeah, that was basically it.
There's no purpose really. It was more of "wonder if I can" and also nice way to learn custom literals.
Index arrays with ordinals instead of integers with custom literals
I did a code that uses custom literals to allow indexing arrays with ordinals (1st, 2nd, 3rd), all at compile time. Additionally _st works only with 1, _nd only with 2, _rd only with 3. Zero and negative numbers are also not supported and fail compilation.

histat - a simple history stats

I created a very simple script that shows the history usage of your shell. Should work with bash and fish shells.
This basically goes through the history and counts the command names. So all of git push, git pull, etc will count as just git.
Example output:
undefined
847 pacman
296 cd
206 git
203 time
180 vim
172 awk
166 aur
142 strace
141 cat
125 ls
Total commands: 7008
Unique commands: 753
I can actually define this in TCL:
tcl
% proc ifn't {cond cmds} {if {!$cond} {uplevel $cmds}}
% ifn't false {puts 12}
12
% ifn't true {puts 12}
%
