Why Is Common Lisp Not the Most Popular Programming Language?
No, it's difficult to read, and understand. It's a parenthesis circus, example -
https://github.com/dimitri/pgloader/blob/master/src/sources/...
-
We need to talk about parentheses
Examples (for Common Lisp, so not citing Emacs): reddit v1, Google's ITA Software that powers airfare search engines (Kayak, Orbitz…), Postgres' pgloader (http://pgloader.io/), which was re-written from Python to Common Lisp, Opus Modus for music composition, the Maxima CAS, PTC 3D designer CAD software (used by big brands worldwide), Grammarly, Mirai, the 3D editor that designed Gollum's face, the ScoreCloud app that lets you whistle or play an instrument and get the music score,
but also the ACL2 theorem prover, used in the industry since the 90s, NASA's PVS provers and SPIKE scheduler used for Hubble and JWT, many companies in Quantum Computing, companies like SISCOG, who plans the transportation systems of european metropolis' underground since the 80s, Ravenpack who's into big-data analysis for financial services (they might be hiring), Keepit (https://www.keepit.com/), Pocket Change (Japan, https://www.pocket-change.jp/en/), the new Feetr in trading (https://feetr.io/, you can search HN), Airbus, Alstom, Planisware (https://planisware.com),
or also the open-source screenshotbot (https://screenshotbot.io), the Kandria game (https://kandria.com/),
and the companies in https://github.com/azzamsa/awesome-lisp-companies and on LispWorks and Allegro's Success Stories.

We migrated our PostgreSQL database with 11 seconds downtime
I worked on migrating our MySQL system to PostgreSQL using pgloader ( https://pgloader.io/ ).
There were some hiccups, things that needed clarification in documentation, and some additional processes that needed to be done outside of the system to get everything we need in place, it was a amazing help. Not sure the project would've been possible without it.
Data mapping from PostgreSQL to PostgreSQL as in the article isn't nearly as bad as going between systems. We took a full extended outage and didn't preload any data. There were many dry runs before hand and validation before hand, but the system wasn't so mission critical that we couldn't afford to shutoff the system for a couple of hours.

Time For Me To Fly… To Render
Initially, I started down the pgloader path, which seemed to be a common approach for the database conversion. However, using my M1-chip MacBook Pro led to some unexpected issues. Instead, I opted to use NMIG to convert MySQL to PostgreSQL. For more information, please check out the “Highlights From the Database Conversion” section below.

PostgresSQL DB restore sature whole SAN IO
I just checked pgloader (which is mostly for heterogeneous database migrations) and it doesn't seem to have any explicit throttling features, either. However, you can set concurrency, number of workers, and batch size.
-
What language should i learn?
But do what makes you happy. The best PostgreSQL data loader in the world is written in Common Lisp. Now, CL is a fast and ANSI standardized language with multiple implementations, and was used to create Reddit, but it's hard to call it fashionable.
-
Why Lisp?
- [ScoreCloud](https://scorecloud.com/) - A web and mobile application to automatically create music notation from music performance or recordings. Built with LispWorks.
## DB tools
- [Pgloader](https://github.com/dimitri/pgloader/) - Migrate to PostgreSQL in a single command!. [PostgreSQL License]
-
What ETL tool you use with Postgres ?
I would warmly recommend https://pgloader.io but, unfortunately, the Oracle support is still in need of a sponsor :-)
-
Installing pgLoader on RHEL9 - No matching package to install: 'sbcl' - is there a workaround?
I followed instruction here: https://github.com/dimitri/pgloader/blob/master/INSTALL.md, but can't get pass sbcl requirement.

Introducing pgsqlite, a pure python module for import sqlite into postgres
https://pgloader.io/ There's been a great tool available for this for many years.

Angular Signals: Best Practices
Besides the dangers, mentioned by Angular docs (infinite loops, change detection errors), there is another thing, that might be quite nasty: effects are executed in a reactive context, and any code you call in effect, will be executed in a reactive context. If that code reads some signals, they will be added as dependencies to your effect. Here Alex Rickabaugh explains the details.

Understanding control flow syntax in Angular 17
In June 2023, the Angular team raised a new RFC to implement control flow syntaxes within Angular. They gave the following rationale for introducing control flow syntax:

⏰ It’s time to talk about Import Map, Micro Frontend, and Nx Monorepo
Just to give you more context, I led the migration of several AngularJS applications to the newer Angular Framework. My client finally decided to make that move following the AngularJS deprecation announcement (stay up to date please 🙏)️.
