Automatically switch node versions between projects
At my day job we work with Node 12 for our projects, but I wanted to check out NuxtJS 3, which requires version 14 or 16. Once I updated npm, I found out me old projects no longer worked properly.

So, I looked into finding a solution. And found one! Read More »

That is, the language in which I'm most proficient are all very high-level languages: Python, PHP, XSLT, Bash, JavaScript, Ruby, C# (in order of decreasing (recency of) experience. I have never mastered a so-called systems language: C, C++, Rust.

Gitlab ‘Your password expired. Please access GitLab from a web browser to update your password.’
I just fixed a very obscure error in Gitlab of 'Your password expired. Please access GitLab from a web browser to update your password.' This error would appear during SSH operations, and in various log files in /var/log/gitlab. Also XHR requests to the server got that response.
