Hi! I’ve started writing a blog on Julia at [T.E.C.H. - Martin Alfaro](https://alfaromartino.github.io/blog).

I’m a relatively new user of Julia, and my goal is to share various approaches that have worked for me. **The posts about Julia are written for anyone, regardless of their background** —I’ll make it clear when the posts are about Economics, so you can ignore them if it’s not your field.

The blog will also **provide templates that can be used off the shelf** , or at least serve as a base to start from. An example of this is the second post of the blog, which explains how to draw world heatmaps in Julia.

To facilitate the reading, **I’ve developed a layout to make the reading straightforward**. For example, I present codes in horizontal tabs for easy comparison. These tabs have automatic heights set through JavaScript, and you can use keyboard shortcuts (ctrl+upArrow or ctrl+DownArrow) to open and close all code snippets. Each post also includes a jl file with the codes used, in case someone wants to experiment.

Technically, I’ve taken advantage of the flexibility of **Franklin.jl** by @tlienart. It has allowed me to automate multiple aspects and write each post effortlessly.

Hope you enjoy it!

This is fantastic! I think you can expand on allocations by summarizing the tips in [this thread](https://discourse.julialang.org/t/common-allocation-mistakes/66127), which I wish I had found when I was starting with Julia.

Thanks! I’m planning on writing two more parts about efficiency improvements, one of them covering pre-allocation of outputs.

Maybe it could be a good idea to use this thread to announce when a new post is released. In principle, I’m planning on one article per week.

I’m also writing a (free) online book for a course on Julia I’ll be teaching next semester. It’ll cover all these aspects more systematically, which is not possible in a blog. There should be a first version in about two months.

Here is the list of the topics of the first two parts of the book, and also the style of the book.
