Tech stuff: Julia, Vim & Vizardry

Been doing lots of tech stuff lately. Here’s a sharing of some highlights.

Through the years I’ve been programming in more than a dozen different languages. Since many years I have more or less settled on Ruby besides my HP-41 projects programmed in FOCAL and MCODE. Now and then I get this urge to learn a new programming language, and after an extensive search for something neat, I finally landed on Julia. I’m trying her out while reading the book, “Getting started with Julia Programming Language“.

The book is good. The programming language seems excellent. It boasts a complete GitHub-based package system to extend the language with various modules. Although it’s a general purpose language, its strength lies in maths and natural sciences. It’s very fast and with a pretty clean and natural syntax. You can even do straight forward math like this:

f(x) = 2sin(3x)^2

And by then executing the function “f” with x as 0.8, you get the answer straight:

f(0.8)
0.9125010165605526

There is a chance I could be falling in love here 🙂

I’ve also been doing lots of work on my Conky setup resulting in this as my “bare” desktop:

Then there is VIM – perhaps my the tool I use the most. I’ve been using VIM for writing everything from HyperLists and notes to e-mails, short stories and books since around 2001. It’s a fantstic text editor. But it lacks a good package manager for add-ons :-/

But then I found Vizardry. Using Pathogen as a base to install extensions, Vizardry will let you search for add-ons, install it with a breeze and remove it just as easily. If you’re a VIM user, this is a must. Go get it! You will thank me 🙂
