The Free Software Foundation Europe (FSFE), European Digital Rights (EDRi), and 34 other open source and digital rights advocacy groups has published an open letter to EU legislators calling for new legislation that will require code paid for by the people to be made available as Free and open source software. “Public Money? Public Code!”
The open letter, signed by tens of organizations and thousands of individuals, calls on EU legislators to:
Every year since 2009, a group of KDE developers gathers in Randa, Switzerland for a large sprint. The event – called Randa Meetings – usually has a theme, and this year it’s accessibility.
From making software more usable for people with disabilities to improving navigation and scalable fonts that will benefit everyone, the activities planned for Randa 2017 are ambitious and in the spirit of Free Software.
Anyone can support the developers by donating to the official Randa 2017 fundraiser, and help bring those plans closer to reality.
Delivering RPM packages securely and continuously with Jenkins and Hashicorp Vault: When you publicly deliver more than eight releases a day—like we do for Tuleap—making sure that users can verify the authenticity of the deliverables becomes a challenge. Over the past few weeks we have modified our Jenkins build pipelines to GPG sign every RPM package we deliver, thus enhancing the level of security we bring to every Tuleap user.

How to test the network speed/throughput between two Linux servers: I have setup total four servers in cloud based data center. They run either CentOS or Ubuntu Linux. I need to make sure clustered file system performance is reasonable as my servers shared with other users. How do I check the speed between the two Linux servers using command line options for private LAN/VLAN?
LINUX FU: BETTER BASH SCRIPTING: It is easy to dismiss bash — the typical Linux shell program — as just a command prompt that allows scripting. Bash, however, is a full-blown programming language. I wouldn’t presume to tell you that it is as fast as a compiled C program, but that’s not why it exists. While a lot of people use shell scripts as an analog to a batch file in MSDOS, it can do so much more than that. Contrary to what you might think after a casual glance, it is entirely possible to write scripts that are reliable and robust enough to use in many embedded systems on a Raspberry Pi or similar computer.
How to Size Your MongoDB Clusters: Overprovisioning remains a rampant problem, which companies such as Qubole aim to solve through automation. It can be costly when using public clouds if companies pay for more capacity than they need to run their workloads. Underprovisioning, however, can lead to dire performance problems and customer churn.
