WSL 2 - Enabling systemd

Enable systemd in WSL 2

NOTE: If you have Windows 11 there is now an official way to do this in WSL 2, use it if possible - see MS post here (WINDOWS 11 ONLY)

This guide will enable systemd to run as normal under WSL 2. This will enable services like microk8s, docker and many more to just work during a WSL session. Note: this was tested on Windows 10 Build 2004, running Ubuntu 20.04 LTS in WSL 2.

  • To enable systemd under WSL we require a tool called systemd-genie

  • Copy the contents of install-sg.sh to a new file /tmp/install-sg.sh:

Ordering a query result set by an arbitrary list in PostgreSQL

I'm hunting for the best solution on how to handle keeping large sets of DB records "sorted" in a performant manner.

Problem Description

Most of us have work on projects at some point where we have needed to have ordered lists of objects. Whether it be a to-do list sorted by priority, or a list of documents that a user can sort in whatever order they want.

A traditional approach for this on a Rails project is to use something like the acts_as_list gem, or something similar. These systems typically add some sort of "postion" or "sort order" column to each record, which is then used when querying out the records in a traditional order by position SQL query.

This approach seems to work fine for smaller datasets, but can be hard to manage on large data sets with hundreds (or thousands) of records needing to be sorted. Changing the sort position of even a single object will require updating every single record in the database that is in the same sort group. This requires potentially thousands of wri

Getting rid of nokogiri segfaults

This readme is a mixture of everything I read on SO+nokogiri wiki, which ultimately worked out for me.

Here are the steps which worked for me to get rid of segfaults with Nokogiri 1.4.4, on both Lion and Snow Leopard, with Ruby 1.8.7 (patchlevel 334 and +).

First diagnose which version of libxml2 you're using:

bundle exec nokogiri -v

If you have 2.7.3 listed somewhere, you're in bad waters (known to segfault). Install this:
