KDE neon upgrade - From 16.04 to 18.04

I am quite happy with the KDE neon upgrade, going from the 16.04 to the 18.04 base. I think it's good on several levels, including improved hardware support and even slightly better performance. Plus there were no crashes or regressions of any kind, always a bonus. This means that neon users now have a fresh span of time to enjoy their non-distro distro, even though it's not really committing to any hard dates, so the LTS is also only sort of LTS in that sense. It's quite metaphysical. On a slightly more serious note, this upgrade was a good, positive experience. I semi-accidentally tried to ruin it, but the system recovered remarkably, the post-upgrade results are all sweet, and you have a beautiful, fast Plasma desktop, replete with applications and dope looks and whatnot. I'm happy, and we shall bottle that emotion for when the need arises, and in the Linux world it does happen often, I shall have an elixir of rejuvenation to sip upon. KDE neon, a surprisingly refined non-distro distro. Read more

Games: Starsector, Squally, Where The Water Tastes Like Wine: Fireside Chats, 103

  • Open-world single-player space-combat RPG 'Starsector' has a major new release out and it's awesome
    Starsector (formerly "Starfarer") is a game that I've followed for quite a few years now, one I personally purchased many years ago and the latest release is a big one. I've tested it at various points over the years, always coming away impressed by the visual design just as much as the gameplay. The spaceship design really is quite incredible. Thankfully, the issues that plagued the Linux version (for me) in the past are gone. Multi-monitor support has vastly improved, with it not messing with my secondary monitor and going fullscreen correctly on my primary monitor. That alone, is a big deal for me and it's so much nicer.
  • Squally now has the Early Access release on Linux with the Hexus card mini-game available
    Squally is what they're calling a 2D puzzle RPG, which is supposed to teach you "video game hacking" without needing prior experience and no "boring lessons".
  • Where The Water Tastes Like Wine: Fireside Chats, a free standalone adventure is out
    Where The Water Tastes Like Wine: Fireside Chats acts as a free standalone companion to Where The Water Tastes Like Wine and it's out with Linux support.
  • First-person mystery adventure '103' will have Linux support at release
    103 is a rather stylish and intriguing first-person mystery adventure that's releasing next month and it will have Linux support at release. A game we covered previously as it was on Kickstarter, they managed to hit over their funding goal in in September by other seven thousand Australian dollars so they did quite well. In reply to a user question on Steam earlier this month, the developer noted that the Linux version will in fact be available at release so that's some rather nice news to see them so positive about it.

Linus Torvalds Comments On STIBP & He's Not Happy - STIBP Default Will End Up Changing

It turns out that Linus Torvalds himself was even taken by surprise with the performance hit we've outlined on Linux 4.20 as a result of STIBP "Single Thread Indirect Branch Predictors" introduction as well as back-porting already to stable series for cross-hyperthread Spectre V2 protection. He doesn't want this enabled in full by default. All of the benchmarking I've been doing the past few days to shine the light on the Linux kernel's STIBP addition appears to be paying off. My tests have found Linux 4.20 to incur significant performance penalties in many workloads -- in fact, more so than some of the earlier Spectre and Meltdown mitigations -- and STIBP is already being back-ported to stable series like Linux 4.19.2. PHP, Pythom, Java, and many other workloads are measurably affected and even the gaming performance to some extent. Read more
