The bigger you are, the more small efficiencies add up. Manivannan Selvaraj's talk from LinuxCon North America gives us a detailed inside view of how PayPal cut operating costs by a factor of ten, while greatly increasing performance and user convenience.
Everything has to be fast now. We can't have downtimes. No going offline for maintenance, no requesting resources with a days-long ticketing process. Once upon a time virtual machines were the new miracle technology that enabled more efficient resource use. But that was then. Selvaraj describes how PayPal's VMs were operating at low efficiency. They started with a single giant customized Jenkins instance running over 40,000 jobs. It was a single point of failure, not scalable, and inflexible.
Turn Raspberry Pi 3 Into a Powerful Media Player With RasPlex
I have hundreds of movies, TV shows and music that I have bought over the years. They all reside on my Plex Media Server. Just like books, I tend to buy these works and watch them once in awhile, instead of relying on "streaming" services like Netflix where content isn’t always available forever.
If you already have Plex Media Server running, then you can build an inexpensive Plex Media Player using Raspberry Pi 3 and RasPlex. Plex Media Server is based on open source Kodi (formerly XBMC), but is not fully open source. Plex Media Center has a friendly interface and it’s very easy to set up a media center (See our previous tutorial on how to install it on a Raspberry Pi 3 or on another dedicated Linux machine).
7 Linux predictions for 2017
Last year I made a set of predictions of events that I thought would happen in the tech world (focused primarily on Linux and free software). I was mostly right. This has emboldened me to make another set of predictions for 2017. I have no inside knowledge on any of these—I am basing this entirely on the twin scientific principles of star maths and wishy thinking.
In addition to Red Hat's Benjamin Otte working on a Vulkan renderer for GTK4's GSK, he's also been working on a big refactoring of the OpenGL code that's now been merged to master.
OpenGL is very important for GTK4 as it will play a big role in rendering with GSK. With this "large GL refactoring", a big clean-up was done of the OpenGL GDK code, affecting the X11, Win32, Wayland, and Mir code too. Some of the specific work includes no longer using buffer-age information, passing the actual OpenGL context, and simplifying the code. More details via this Git commit.
A Vulkan back-end is in development for GNOME's GTK's tool-kit new GTK Scene Kit (GSK) code.
Benjamin Otte has begun experimenting with a Vulkan back-end for GTK's GSK code with GTK Scene Kit being one of the big additions in development for the major GTK+ 4.0 milestone. GSK implements a scene graph to allow for more complex graphical control of widgets and other improvements to its graphics pipeline. GSK was merged back in October and currently uses OpenGL for rendering while there is now a branched Vulkan renderer.
