Altruism is one thing that I'd like to believe characterizes all Linux users out there. This trait can be manifested in a lot of different ways, but when we're talking about computers, the most characteristic and practical way is donating computational resources for a good cause. Here's is a quick guide on how to do exactly that.

Remotely-distributed system administration teams provide around-the-clock coverage without anyone losing sleep, and have the benefit of drawing from a global talent pool.

Linux kernel 4.7 has a LoadPin security module that helps the platform load all the necessary modules from the same file system. It is ported directly from Google's Chrome OS and is aimed to limit the medium from which kernel modules and firmware load on a system.

It was a legal iTunes purchase that helped the feds nab Artem Vaulin, the alleged proprietor of KickassTorrents (KAT), the world's biggest purveyor of illegal torrent files. The irony is almost too much to bear pointing out. But according to one lawyer familiar with the ins and outs of copyright infringement, the case could have sweeping repercussions on how torrents are regulated.

The CORD Project recently became an independent project hosted by The Linux Foundation. CORD (TM) (Central Office Re-architected as a Datacenter), which began as a use case of ONOS®, brings NFV, SDN, and commodity clouds to the telco central office and aims to give telco service providers the same level of agility that cloud providers have to rapidly create new services.

Bluetooth headsets and speakers are now more popular than ever before, but getting them to work under Linux isn't always very clear. With all that is going on in the Linux sound systems world, it is easy to get lost and even give up. Most of the time, the problem with these devices is that your system can see them, but for some reason it can't establish a connection. Here is a quick and simple guide on how to get through this problem. I have tested the following on Arch, but it should work on every other distribution as well.
