Discovering Cloudflare Workers

I developed a small web app that retrieves temporary codes I receive by email. A rather odd idea if the goal is for anyone to be able to log into my accounts… Which was precisely my goal. I had already registered my domains into Cloudflare to catch all received emails. I thought I had explored all the free features of the beast. Apparently not. In this blog post I wrote down how I used Cloudflare Workers to create an app that fetches temporary codes sent by mail, and also 2nd-factor Authentication (2FA) ones, and expose them on a simple website.

Update of my static site ⬆️

I underwent a rather significant overhaul of my blog. I wanted to take a few minutes to write about my approach. This article follows the one on creating the blog.

In fact, it was Hugo that told me, because it was impossible to compile the site on my laptop with a recent version of Hugo. So I had two options:

Single-node Kubernetes with ingresses ☸️

For a friend, I did a Telegram bot and containerized the app with Docker. In reality, that was the beginning of a long struggle to keep only Docker and configure a reverse proxy, because I’m really bad at that. Instead, I installed k3s, which allowed me to have single-node Kubernetes, meaning all running on a single VM. Kubernetes makes it possible to orchestrate containers, thus solving many of my issues.

I spent a few weeks creating a Telegram bot for a very dear friend. Until now, he had been performing the redundant task of posting content on social media using the same template created with Canva. While Canva is very accessible, it still involves redundant steps that can be easily avoided. With chatbots and Telegram making headlines recently, I thought it was a good idea to launch my own chatbot. Here’s how I did it.

Set up a Catch-All email for cheap 📥

Until now, whenever a restaurant or website asked for my email address, I was reluctant to give out my real address.

Host your blog for 0€ 💸

LinkedIn, Meta and Twitter want them down! To create content in the 20’s era (from 2020 on), there is a plethora of platforms. Some are newborns (Mastodon, Notion), some are ephemeral (Google +, Skyblog), some are somewhat disliked (Facebook, Twitter), these have a life sometimes shorter than your washing machine. But there is one platform that does not suffer from programmed obsolescence: blogs. In the first post of my super blog, I wanted to tell you how I made… my blog. Hosted on GitHub , made with Hugo and maintained by me, it (almost) costs me 0€ to keep. I hope that by reading this tutorial, you will be able to realize how easy it is to make your own https://timothechau.vet for nothing.
