For years, people have been using jemalloc with ruby. There were various benchmarks and discussions. Legend had it that Jemalloc 5 didn't work as well as Jemalloc 3.

Then, one day, hope appeared on the horizon. @wjordan offered a config for Jemalloc 5.

Things I believe

This is a collection of the things I believe about software development. I have worked for years building backend and data processing systems, so read the below within that context.

Agree? Disagree? Feel free to let me know at @JanStette. See also my blog at www.janvsmachine.net.

Fundamentals

Keep it simple, stupid. You ain't gonna need it.

Notes on the setup

Update 2023/03/02: Using Pop!_OS 22.04 LTS. Just install and enjoy, not much to say about, it just works.

Update 2020/05/19: I'm using PopOS 20.04. Works great!!

NOTE: At the moment Dell G3 series doesn't officially support Ubuntu 18.04.

Using minitest to regression-test your Jekyll static site

I recently had to upgrade my blog, which involved changes such as:

• Replacing a sitemap plugin
• Upgrading from jekyll 2.5.3 to 3.8.4
• Upgrading from jekyll-assets 0.7.8 to 3.0.11
• (etc)

The upgrading process was not trivial, and some parts (e.g. RSS, sitemap, or twitter cards tags) are not immediately visible, so I decided to add unit tests on the generated content.

Code is clean if it can be understood easily – by everyone on the team. Clean code can be read and enhanced by a developer other than its original author. With understandability comes readability, changeability, extensibility and maintainability.

General rules

1. Follow standard conventions.
2. Keep it simple stupid. Simpler is always better. Reduce complexity as much as possible.
3. Boy scout rule. Leave the campground cleaner than you found it.
4. Always find root cause. Always look for the root cause of a problem.

Design rules

#If directory exists, delete it and recreates.
