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

If you are on a quest to get rid of your desktop environment and do everything from the console, well good luck with that.

Virtual Users And Domains With Postfix, Courier, MySQL And SquirrelMail (Ubuntu 14.04LTS) This document describes how to install a Postfix mail server that is based on virtual users and domains, i.e. users and domains that are in a MySQL database. I'll also demonstrate the installation and configuration of Courier (Courier-POP3, Courier-IMAP), so that Courier can authenticate against the same MySQL database Postfix uses.

UltraDNS said it has mitigated a distributed denial of service (DDoS) attack for most of its customers after the service was held down for most of the day. "Currently, only customers utilizing a segment of UltraDNS Name Server addresses are experiencing resolution latency due to intermittent network saturation in the Western US," said Neustar director of product management, security solutions, Jim Fink in an email to Threatpost.

Avalue announced a 3.5-inch SBC and a Qseven format COM supporting the full range of Intel Atom E3800 SoCs and equipped with a wide range of PC-style I/O. Avalue is a bit late in announcing these new embedded boards based on Intel’s 22nm Atom E3800 system-on-chip, although being on Intel’s embedded roadmap, the SoCs will […]

I love SSH. I mean, I really, really love SSH. It's by far the most versatile, useful, amazingly powerful tool in my system administration quiver. One of the problems with SSH, however, is that when it dies, it doesn't automatically recover. Don't get me wrong.

Who doesn't know the challenges in complex project teams and organizations? Multiple projects need to be managed, often with various dependencies to other teams, partners, external suppliers or other parties. Different stakeholders require a different level of information. Questions arise and often cannot be answered satisfactory in many project teams: What is the timeline of our project? What needs to be done to reach the next milestone? How can we track dependencies to other parties in the project plan? Surprisingly, even with the existing OSS tool environment for project management, teams are often still not able to manage complexity.

Virtual Hosting With PureFTPd And MySQL (Incl. Quota And Bandwidth Management) On Fedora 20 This document describes how to install a PureFTPd server that uses virtual users from a MySQL database instead of real system users. This is much more performant and allows to have thousands of ftp users on a single machine. In addition to that I will show the use of quota and upload/download bandwidth limits with this setup. Passwords will be stored encrypted as MD5 strings in the database.

Suppose you are a go to person among your friends and family when it comes to Linux related questions. Someone asked you how to install and configure a tool, and you wanted to show the procedures. How would you do that if he or she is not in front of you? There could be various ways (e.g., by documenting and emailing the procedures, or explaining verbally over the phone, etc), but probably the most clearcut solution would be to demonstrate it yourself. If the demonstration only requires a terminal, then the best way would be use terminal screencast or terminal session recorder.
