=> ↺ Chataigne: An Open-Source Swiss Army Knife
[Ben Kuper] is a developer with a history of working on art installations, and had hit upon a common problem often cited by artists. When creating installations involving light, sound, and motion, they often spend too much time on the nuts and bolts of electronics, programming, and so on. Such matters are a huge time sink with a steep learning curve and oftentimes just a plain distraction from the actual artistic intent they’re trying to focus upon. [Ben] has been working for a few years on a software tool, Chataigne which is designed as the glue between various software tools and hardware interfaces, enabling complex control of the application using simple building blocks.
libcpucycles is a public-domain microlibrary for counting CPU cycles. Cycle counts are not as detailed as Falk diagrams but are the most precise timers available to typical software; they are central tools used in understanding and improving software performance.
=> ↺ Databases in 2022: A Year in Review
Another year has gone by, and I’m still alive. As such, it is an excellent time to reflect on what happened in the world of databases last year. It was quiet in the streets as the benchmark wars between DBMS vendors have quieted down. I had fun writing last year’s retrospective, so I am excited to share with you the things that stand out from 2022 and my thoughts on them.
XML is precisely what it says on the tin: an extensible markup language. It’s a markup language with a completely uniform syntax so that the alphabet of markup elements is customizable. And for what it is, there is truly no replacement. Every other markup language supports only a limited set of markup directives defined from the factory. The tradeoff is generality for ease of authoring: limited markup languages can have terser syntax for specific elements.
So why did XML come to be used as a data exchange language? Partly because, despite its roots in SGML (the Common Lisp of markup languages), the creators advertised it as a general format to exchange any digital information.
If you’re a software/hardware person or a techie, you surely can help developing tools to help people not only in Iran, but every other place or people needing tools to access basic available daily stuff such as a social network or a communication tool or even reading an article and getting information. You can contact your friends discussing the needs and required tools to get started. The simplest act can be running Snowflake extensions and help people connecting to free [Internet] using Tor.
