SSL, HTTP/2, Service Worker, Offline Mode? This blog has all of them

I usually see myself spending more time migrating from one setup to another one than writing valuable content. After all, I consider my blog a playground where I try some concepts.

It is still not very over-engineered and being open sourced and available on GitHub I thought someone could benefit from it.

Reading List

I have decided to collect some of the best posts and articles I have read during last days. It is inspired by Bruce Lawson’s reading lists and web development newsletters. I write it to keep track of interesting content for myself, but you might also find it useful.

Assessing New Technology

Try this library, it’s the best thing ever. Try this technique, it will make your site automatically faster. I read and hear people praising libraries or technologies very often. It can come as a blog post, talk at a conference or informal conversation. It is fine to talk about the benefits of using A over B, but be alert if A doesn’t seem to have any drawbacks.

Using MediaRecorder API for screen recording on the web

At CSSConf AU 2016, Soledad Penadés gave a talk called “Real time front-end alchemy“. It was full of examples of combining MediaStreams with audio and video manipulation.

Something I didn’t know was that you can record audio and video on the browser without any plugins. You can combine audio from the microphone, video from a canvas, dynamically generated content… you name it. Even recording a window or the entire screen and exporting it as a video.

In this post I give a short introduction about the event and I include links to the slides, videos and the script. The CSSConf AU 2016 sign at the entrance

JPG compression level, SSIM and Jpeg.io

The size of images in JPG varies a lot based on the compression level we choose when saving them. Often, we tweak this level by hand until we consider we don’t have too many artifacts and the resulting image is close enough to the original one.

The same compression level doesn’t generate the same amount of artifacts in two different images. We need to find an automated approach that measures how different (or similar) two images are, and loop through several compression levels to find the most suitable one.

Some things I learned implementing Data Fetching for Universal Web Apps

Javascript is not just a language for the browser. Node.JS is becoming popular as a platform to run JS on the server. We are learning how to build modular websites where business logic and state are not coupled with the markup. And finally we are getting the tools to build universal web apps. But what are universal apps, and why should we care about data fetching?

The importance of personal side projects

This blog you are reading is more a tool for me to consolidate some ideas and experiences I come across. So is my GitHub account, where I upload some small projects that otherwise would remain on my computer and eventually die. It is also a way of giving back: I have learned may things reading other people’s posts and code, and I hope someone can find what I do useful.
