AI: open source's next big win.

I avoided using GNU Make in my data journalism work for a long time, partly because the documentation was so obtuse that I couldn’t see how Make, one of many extract-transform-load (ETL) processes, could help my day-to-day data reporting. But this year, to build The Money Game, I needed to load 1.4GB of Illinois political contribution and spending data every day, and the ETL process was taking hours, so I gave Make another chance. Now the same process takes less than 30 minutes. read more

I manage a personal website and edit the web pages by hand. Since I don't have many pages on my site, this works well for me, letting me "scratch the itch" of getting into the site's code. When I updated my website's design recently, I decided to turn all the plain quotes into "smart quotes," or quotes that look like those used in print material: “” instead of "". read more

Cuda is a parallel computing platform created by Nvidia that can be used to increase performance by harnessing the power of the graphics processing unit (GPU) on your system. In this tutorial, we will learn how to install Cuda on Ubuntu 18.04.

If you are you looking for a way to move your students (or yourself) from programming in Scratch to learning Python, I recommend you look into EduBlocks. It brings a familiar drag-and-drop graphical user interface (GUI) to Python 3 programming.

In a previous article, you learned how to use the MusicBrainz service to provide tag information for your audio files, using a simple Python script. This article shows you how to also script an all-in-one solution to copy your CDs down to a music library folder in your choice of formats.

In this edition of our open source news roundup, we take a look at NASA's open source mars rover, Rome's latest open source efforts, two new research projects, and more. NASA open sources design for a Martian rover Do you want to build your own Mars rover? Of course you do! And now you can, thanks to NASA's JPL Open Source Rover (OSR for short).

Libre Linux for wireless, embedded kit unforks OpenWRT and LEDE The OpenWRT project has emitted version 18.06, and in doing so, puts to rest the damage done by the March 2016 fork that created the competing project LEDE (Linux Embedded Development Environment).…

Mickaël Salaün posted a patch to improve communication between landlocked processes. Landlock is a security module that creates an isolated "sandbox" where a process is prevented from interacting with the rest of the system, even if that process itself is compromised by a hostile attacker. The ultimate goal is to allow regular user processes to isolate themselves in this way, reducing the likelihood that they could be an entry point for an attack against the system.

When people talk about diversity and inclusion in open source, the discussion is usually about how to improve a project culture's inclusivity. But can the software itself be gender biased? Our research says it can. So, how do you know if your software is biased? And, if it is, how can you make it more inclusive? The GenderMag method is a way to identify gender-inclusiveness problems in your software. It is available in a "kit" freely available for download at GenderMag.org. read more

instead of saying you should use Tool X and Tool Y, I’m going to narrow it down to five categories and then offer up an example for each. Just remember, for most categories, there are several available options. And, with that said, let’s get started.
