There are the obvious ones, like the amazing Ardour digital audio workstation (DAW) and Audacity, the ubiquitous waveform editor and all-around Swiss Army knife. And then there are those lesser-known applications that hum away happily, developed by a team of dedicated programmers and powering all manner of creative output.

How to avoid humiliating newcomers: A guide for advanced developers

Friday 16th of March 2018 07:01:00 AM

Every year in New York City, a few thousand young men come to town, dress up like Santa Claus, and do a pub crawl. One year during this SantaCon event, I was walking on the sidewalk and minding my own business, when I saw an extraordinary scene. There was a man dressed up in a red hat and red jacket, and he was talking to a homeless man who was sitting in a wheelchair. The homeless man asked Santa Claus, "Can you spare some change?" Santa dug into his pocket and brought out a $5 bill. He hesitated, then gave it to the homeless man. The homeless man put the bill in his pocket.

Linux Kernel 4.15 Reached End of Life, Users Urged to Move to Linux 4.16 Now

After a very busy cycle due to the Meltdown and Spectre security vulnerabilities, which were publicly disclosed earlier this year and later discovered to put billions of devices using modern processors at risk of attacks, the Linux 4.15 kernel series was released at the of January heavily redesign against two critical hardware bugs. Now, nearly three months and only eighteen maintenance updates later, the Linux 4.15 kernel series reached end of life and it will no longer receive support. As such, all those using a kernel from the Linux 4.15 branch on their GNU/Linux distributions are urged to upgrade to the latest Linux 4.16 kernel series as soon as possible. Read more

This Chart Shows How The Radeon RX 580 vs. GeForce GTX 1060 Now Compete Under Linux

It was just last year that open-source RadeonSI/RADV developers were trying to get the Radeon RX 580 "Polaris" GPU to be competitive with the GeForce GTX 1060 as it is under Windows given each GPU's capabilities. We've seen the RX 580 and GTX 1060 dancing under Linux the past few months and yesterday's 20-way GPU comparison with Rise of the Tomb Raider was quite significant -- perhaps most surprising being how well the RX 580 performed. Heck, just one or two years ago it was an accomplishment seeing any official Radeon driver support at-launch for new Linux game releases. So here are some extensive tests looking closer at the GTX 1060 vs. RX 580 battle in this latest Vulkan-powered Linux game port. Read more
