The Complete Guide to PlayStation Emulation on Ubuntu

Wednesday 13th of June 2018 05:09:41 PM
The original Playstation was undoubtedly a great game console. It was the first console to bring disk-based games to the mainstream, and it was home to a whole host of now classic games, spawning more than a few legendary franchises. The day of the PS1 has long passed, but the games are still great, and the options to play them now are unfortunately limited. However, there is hope with emulators. For Linux systems like Ubuntu, one of the best emulators is PCSXR, and it’s available right from the default Ubuntu repositories.

Systemd Services: Reacting to Change

Wednesday 13th of June 2018 09:43:40 AM
In prior installments, we saw that systemd services can be started or stopped by hand or when certain conditions are met. Those conditions are not limited to when the OS reaches a certain state in the boot up or powerdown sequence but can also be when you plug in new hardware or when things change in the filesystem. You do that by combining a Udev rule with a systemd service.

openSUSE Tumbleweed Is Now Powered by Linux Kernel 4.17, KDE Plasma 5.13 Landed

As of today, the openSUSE Tumbleweed rolling operating system is now powered by the latest and most advanced Linux 4.17 kernel series, which landed in the most recent snapshot released earlier. Tumbleweed snapshot 20180615 was released today, June 17, 2018, and it comes only two days after snapshot 20180613, which added the Mesa 18.1.1 graphics stack and KDE Plasma 5.13 desktop environment, along with many components of the latest KDE Applications 18.04.2 software suite.

As such, OpenSuSE Tumbleweed is now officially powered by Linux kernel 4.17, so upgrading your installs as soon as possible would be a good idea. Read more

today's howtos and leftovers

OSS Leftovers

  • Using Open Source Software in a SecDevOps Environment
    On 21 June 2018 the Open Source Software3 Institute is hosting a discussion that should be of high interest to enterprise technologists in the DC/Northern Virginia, Maryland area. From their invite: Come hear from our panelists about how the worlds of Open Source Software and the Secure Development / Operations (SecDevOps) intersect and strengthen one another. SecDevOps seeks to embed security in the development process as deeply as DevOps has done with operations, and Open Source Software is a major factor in Security, Development, and Operations. Tickets are free, but you need to register soon because seating is limited.
  • TenFourFox FPR8b1 available
    TenFourFox Feature Parity Release 8 beta 1 is now available (downloads, release notes, hashes). There is much less in this release than I wanted because of a family member in the hospital and several technical roadblocks. Of note, I've officially abandoned CSS grid again after an extensive testing period due to the fact that we would need substantial work to get a functional implementation, and a partially functional implementation is worse than none at all (in the latter case, we simply gracefully degrade into block-level divs). I also was not able to finish the HTML input date picker implementation, though I've managed to still get a fair amount completed of it, and I'll keep working on that for FPR9. The good news is, once the date picker is done, the time picker will use nearly exactly the same internal plumbing and can just be patterned off it in the same way. Unlike Firefox's implementation, as I've previously mentioned our version uses native OS X controls instead of XUL, which also makes it faster. That said, it is a ghastly hack on the Cocoa widget side and required some tricky programming on 10.4 which will be the subject of a later blog post.
  • GNU dbm 1.15
    GDBM tries to detect inconsistencies in input database files as early as possible. When an inconcistency is detected, a helpful diagnostics is returned and the database is marked as needing recovery. From this moment on, any GDBM function trying to access the database will immediately return error code (instead of eventually segfaulting as previous versions did). In order to reconstruct the database and return it to healthy state, the gdbm_recover function should be used.

Server: GNU/Linux Dominance in Supercomputers, Windows Dominance in Downtime

  • Five Supercomputers That Aren't Supercomputers
    A supercomputer, of course, isn't really a "computer." It's not one giant processor sitting atop an even larger motherboard. Instead, it's a network of thousands of computers tied together to form a single whole, dedicated to a singular set of tasks. They tend to be really fast, but according to the folks at the International Supercomputing Conference, speed is not a prerequisite for being a supercomputer. But speed does help them process tons of data quickly to help solve some of the world's most pressing problems. Summit, for example, is already booked for things such as cancer research; energy research, to model a fusion reactor and its magnetically confined plasma tohasten commercial development of fusion energy; and medical research using AI, centering around identifying patterns in the function and evolution of human proteins and cellular systems to increase understanding of Alzheimer’s, heart disease, or addiction, and to inform the drug discovery process.
