Analysis In the 1990s, Intel and Microsoft dominated the "open" PC standard – and it appears that Google now wants to do the same for its Android system, via its Silver programme.

In my last article, I looked at NumPY and some of its uses in numerical simulations. Although NumPY does provide some really robust building blocks, it is a bit lacking in more sophisticated tools. SciPY is one of the many Python modules that build on NumPY's.

Death from above brought to you by the happy, peaceful world of open source Hey, Linux fans: a high-profile, colossal, global outfit is about to dump a proprietary operating system and replace it with Linux in a very, very, demanding application that literally involves life and death situations.…

When I walked into Carroll Hall, for a moment I felt like I was back in college... and at the World’s Best Slumber Party. There were tables full of salty snacks, stacks of sleeping bags, and the chatter of excited young women. But, unlike the sleepovers of my youth, talk was about Python, HTML, and Ruby. These were young women interested in learning to code.

Logical Volume Manager (LVM) is a versatile disk management system that can easily be used in Linux or similar operating systems. traditional partitions are created in fixed sizes, and resizing them is a tedious process. On the other hand, LVM creates and manages "logical" volumes off of physical hard disks, and provides administrators the flexibility […]Continue reading...

I do a lot of work on open source, but my most valuable contributions haven't been code. Writing a patch is the easiest part of open source. The truly hard stuff is all of the rest: bug trackers, mailing lists, documentation, and other management tasks. Here's some things I've learned along the way.

The Perfect Server - Ubuntu 14.04 (nginx, BIND, MySQL, PHP, Postfix, Dovecot and ISPConfig 3) This tutorial shows how to prepare an Ubuntu 14.04 (Trusty Tahr) server (with nginx, BIND, Dovecot) for the installation of ISPConfig 3, and how to install ISPConfig 3. ISPConfig 3 is a webhosting control panel that allows you to configure the following services through a web browser: Apache or nginx web server, Postfix mail server, Courier or Dovecot IMAP/POP3 server, MySQL, BIND or MyDNS nameserver, PureFTPd, SpamAssassin, ClamAV, and many more. This setup covers nginx (instead of Apache), BIND (instead of MyDNS), and Dovecot (instead of Courier).

A roundup of events in Fedora.

A project's choice of a license will have significant effects on its ability to sustain itself. Despite the rivers of ink that have flowed regarding the recent Heartbleed vulnerability, I believe the developer community has not addressed the right problem. Developers have fixated on a debate about one of open-source's most touted advantages: With many eyes looking at the code, is open source able to correct bugs faster than closed-source projects?

When AMD revealed an “ambidextrous” processor roadmap based on both x86 and ARM cores last Fall, it saved one surprise for today: they’ll be pin compatible!

You might be wondering why you might want to attach an Arduino to your Raspberry Pi. While there are lots of reasons, probably the most poignant is the extra six PWM-capable pins and another six analogue pins that a standard Arduino Uno offers.

When it comes to managing infrastructure deployments of a certain size, even a ninja sysadmin can't do it all without some help. In fact, one might argue that knowing when and how to use IT automation tools for managing infrastructure is a prerequisite to getting your admin blackbelt. Enter Puppet. 

When it was released in 2011, Drupal 7 was the most accessible open source content management system (CMS) available. I expect that this will be true until the release of Drupal 8. Web accessibility requires constant vigilance and will be something that will always need attention in any piece of software striving to meet the Web Content Accessibility Guidelines (WCAG) 2.0 guidelines.

Can a compact and low-cost circuit board piggybacked onto the Raspberry Pi microcomputer’s GPIO header turn it into a high-quality audio powerhouse?

Difio is a Django based application that keeps track of packages and tells you when they change. It provides multiple change analytics so you can make an informed decision on when or what to upgrade. Difio was created as closed software, then I decided to migrate it to open source to allow for in-house deployments and attract a larger community around the project. 10 steps to migrate your closed software to open source
