Building a simple ASGI Websocket Application

Jeffrey04 — Sun, 13 Oct 2024 16:51:16 +0000

Getting comfortable to asyncio takes a bit of practice, so I revisited a practice project I did when I was working for my previous company. Suppose I want to build a very simple websocket application, without use of any web application library/framework. In order to keep it simple, I also opt to just build the frontend with minimal setup (just plain ES6 without webpack/vite).

Self-hosted photo album

My cloud storage is nearly exploding, and I am not in a good position to start subscribing for more storage (Yes, I am still #opentowork). Considering I just moved my domain settings to Cloudflare and started using Cloudflare tunnel, I figure I probably should just back up some of my photos, and host it on my workstation.

Adding complexity to the bot: threads and processes

Jeffrey04 — Wed, 18 Sep 2024 08:55:49 +0000

Being new to asyncio, after publishing the previous post on running multiple applications in one event loop, I also cross posted it to the discussion board for feedback. So apparently instead of cramming everything to the same event loop, it would be better if each application run on a separate thread. That makes sense, considering all the code that was written for that.

Learning asyncio by redoing my messaging bot

Jeffrey04 — Wed, 05 Jun 2024 14:03:17 +0000

I used to develop a bot, partly for work, that fetches current latest petrol retail price in Malaysia. The bot was really an experiment, but at the time it worked well. Then a few years later, out of boredom, I revisited the project after finding the telegram bot library is moving towards asyncio. It was great (at least a lot of people rave about it), but also at the same time intimidating, I learned about coroutines and used gevent in the past, but not asyncio itself.

Statistical Analysis for Social Audit Project

This is the formal draft of my statistical analysis report for the social audit project previously mentioned here. As the project is public by nature, I am cross-posting here for own reference.

Refreshing the ReactJS Internet Censorship Dashboard (and Dockerizing Poetry Projects)

Jeffrey04 — Mon, 21 Dec 2020 10:17:20 +0000

The Internet Censorship Dashboard is a project that aggregates data fetched from the OONI API, to provide an overview of the current state of Internet Censorship experienced by users mainly in Southeast Asia. The current form was built a couple of years ago, and recently got funded to get it updated to work better with new APIs.

Revisiting semantic web (plus wheel building with Poetry)

Jeffrey04 — Fri, 18 Dec 2020 10:31:00 +0000

Back then, when I was still working on my postgraduate degree research, I used RDF, which was the preferred format in the world of Semantic Web to represent data. I eventually dropped the degree, and stopped following the development of the related technology and standards. Until I volunteered to update the import script for popit when I was looking for the next job/project.

Working Environment Setup, for 2020

Jeffrey04 — Thu, 17 Dec 2020 10:43:00 +0000

In recent years, I start to make my development environment decouple from the tools delivered by the package manager used by the operating system. The tools (compiler, interpreters, libraries etc) are usually best left unmodified so other system packages that rely on them keeps working as intended. Also another reason for the setup is I wanted to follow the latest release as much as possible, which cannot be done unless I enroll myself to a rolling release distro.

4 Fundamental Things in Programming (pre-101)

Jeffrey04 — Wed, 16 Dec 2020 14:09:16 +0000

Just recently I volunteered to do a pre-101 kinda workshop for people wanting to learn programming. I had done this a few times in the past, but in different settings and goals in mind. The whole structure predates the sessions but I can’t remember when I first created them.

Picking Up Category Theory (and eventually Haskell)

Jeffrey04 — Tue, 15 Dec 2020 15:59:21 +0000

I don’t quite remember when did I first heard about Category Theory, but the term stuck in my head for quite a while. Eventually I attempted to start looking for tutorials on the topic, but it is hard to find one that I actually understand. Most of them are either leaning too much to the Mathematics side, or too much to the Programming side.
