Through the years, I've spent what might seem to some people an inordinate amount of time cleaning up and preserving ancient software. My Retrocomputing Museum page archives any number of computer languages and games that might seem utterly obsolete.

Following on from a set of problems of poor broadband connectivity I was experiencing I decided that I wanted to monitor the Mbps speed I was getting from my provider on a regular basis. I was seeing especially poor figures when trying to download files in the evening, with much faster speeds achieved very early in the morning.

As Android 8.0 debuts a “Project Treble” update plan, all new Android 8.0 devices must run Linux 4.4 or later. Plus: Oreo and Linux 4.13 beef up security.

Plenty of life left in this dinosaur Oracle plans to accelerate the pace of Java SE releases – and has moved Java EE's code repository to GitHub – in keeping with its avowed desire to step back from managing the beast.…

Tinc is an open-source VPN daemon that available for a wide range of platforms and has several advantages over similar VPN clients. A Virtual Private Network (VPN) is a secure private network that operates over a larger public network such as the internet.

It's almost mandatory now for conference organizers to live stream and/or post speakers' recorded presentations on the internet. The good news is that, as we learned in June at EclipseCon France 2017, open source software and affordable technology make it easy to publish videos on YouTube or other video-sharing services without doing any post-editing or rendering—both of which can take a lot of time.

Officially, Oracle hasn't said a thing. Unofficially, if you count the cars in Oracle's Santa Clara office, you'll find hundreds of spots that were occupied last week now empty. As many as 2,500 Oracle, former Sun, employees have been laid off. Good bye, SPARC. Good bye, Solaris. Your day is done.

In any discussion about big-picture topics such as cloud migration services, data centers, and microservices, the topic of enterprise logging can get relegated to an afterthought. But you do so at your peril, because without logging, you won't have critical visibility into your services in order to diagnose and debug efficiently. What's more, if you're a large enterprise, you may be violating compliance requirements.

The Canonical project is gearing up for one of its biggest releases yet. Ubuntu 17.10, due to arrive October 19, will be the company's first release since it abandoned its Unity desktop, Mir display server and the dream of "convergence". Instead Ubuntu users will get the GNOME desktop with a few tweaks that promise to make it a little bit more Unity-like.

Cloud computing has dominated IT discussions for the last two decades, particularly since Amazon popularized the term in 2006 with the release of its Elastic Compute Cloud. In its simplest form, cloud computing is the centralization of computing services to take advantage of a shared data center infrastructure and the economy of scale to reduce costs. read more

In the first part of this series, I presented three challenges open organizations face when seeking strategic, external partners. To quickly recap, these challenges are: Competition with ongoing business for scarce resources in both companies, Divided time, energy, and attention of shared staff, and, Disharmony in partnership and building a new community I also noted that company-to-company alliances typically form through three stages, namely: read more

If you are a Linux command line user, and your work revolves around prime numbers, there's a command line utility that might be of your help. The tool in question is factor, and in this tutorial, we will quickly discuss things like why it exists, how it works, and how you can use it. Please note that all examples and instructions mentioned here have been tested on Ubuntu 16.04LTS.

In this tutorial, I'll explain how to use Pandas and Python to work with messy data. If you have never used Pandas before and know the basics of Python, this tutorial is for you.

In developed countries, the ability to access and edit Wikipedia easily is taken for granted, but in many African countries, where access to reliable electricity and broadband are limited, that's not the case. I recently interviewed Florence Devouard, who is working on several open source projects to help close gaps caused by poor access to online information. read more

When she was only two years old, my daughter was fascinated by the old Eee PC running Ubuntu Studio I was using as one of my main computers. She would climb on my lap to hammer away at the keyboard, so—even though she was a bit young—I decided to search for Linux distributions made for children. To my surprise, I found a few distros made for kids as young as two.
