SMWCon 2021, Development environments using containers

December 9, 2021 by addshore

SMWCon 2021 is happening as I write this post. I was invited to give a short talk as part of a MediaWiki and Docker workshop organized by Cindy Cicalese on day 2. As I am writing a month of blog posts I’m going to turn my slides into a more digestible and searchable online blog post.

The original slides can still be found on Google Slides, and when the conference recording is up you should find it on the associated event page.

Twitter bot powered by Github Actions (WikidataMeter)

Recently 2 new Twitter bots appeared in my feed, fullyjabbed & fullyjabbedUK, created by iamdanw and powered entirely by Github Actions (code).

I have been thinking about writing a Twitter bot for some time and decided to copy this pattern running a cron based Twitter bot on Github Actions, with an added bit of free persistence using jsonstorage.net.

This post if my quick walkthrough of my new bot, WikidataMeter, what it does and how it works. You can find the code version when writing this blog post here, and the current version here.

VSCode & PHP XDebug from Localhost, WSL2 and Docker containers

January 6, 2025February 21, 2021 by addshore

VSCode seems to be one of the up and coming IDEs over the last year. I personally switched from Jetbrains IDEs to VSCode fo most of my development work at some point in 2020.

Apparently up until now I have avoided running the PHP debugger Xdebug. I had to do a little search around to figure out the correct settings for my setup decided to write them down in this handy blog post.

dockerit v0.0.5 (Easier than docker run)

February 21, 2021February 20, 2021 by addshore

dockerit is a small CLI tool that I have been working on during the start of 2021. It’s intended to make running one off commands and CLI tooling easier in docker. Rather than having to write a long string of parameters for docker run, instead you can just use dockerit. This applies to both CLI usage, but also via bash aliases.

You can download a build binary of dockerit from the Github releases page.

Reducing Java JVM memory usage in Containers and on Kubernetes

September 1, 2020May 19, 2020 by addshore

For a while I have been running a Wikibase query service update script for WBStack, which is a Java application on a Kubernetes cluster. Part of that journey has included the updater using all available memory, hitting into the kubernetes memory limit and being OOM killed. The title of the post is a little verbose, but I wanted to include all of the keywords that might help people find the answers to the memory issues that I was running into.

Before getting into my weeds, if you want the answers head straight to https://developers.redhat.com/blog/2017/04/04/openjdk-and-containers/

UPDATE: This blog post was written with Java 8. Java 10+ now automatically recognizes memory limits and enforces them. https://www.docker.com/blog/improved-docker-container-integration-with-java-10/
