GNOME Is Also Getting Fixed Up For Lower CPU Usage With NVIDIA Graphics

tuxmachines.org - Pon, 04/01/2019 - 17:15

Last week I wrote about NVIDIA contributing a fix to KDE/KWin for avoiding high CPU usage when using the proprietary GeForce graphics driver. That fix ended up being due to the KWin compositor making incorrect assumptions about GLX swap buffers behavior. It turns out GNOME also needs a similar fix.

The news coverage of NVIDIA figuring out the fix for KDE also happened to help GNOME developers in figuring out some long-standing similar troubles on their side. Canonical's prolific GNOME contributor, Daniel Van Vugt, has been looking at the NVIDIA high CPU usage bug and was able to confirm he already ended up having a previous but still open merge request that fixes the issue by accident.

  • Linux Gaming News Punch - Episode 6

    Another week has come and gone and as usual you're struggling to follow everything, so here's another episode of the Linux Gaming News Punch.

    Episode 6! I've been doing this over a month now and couldn't be happier with the reception. It's settled nicely now, into a format that works and keeping it under 10 minutes has been really good.

  • The fun single-player FPS Ravenfield now has a new Skirmish game mode and an APC vehicle

    If you're looking for a single-player FPS with large open battles, Ravenfield continues to be a pretty good choice.

    The latest Early Access update adds in a new vehicle, the APC which was apparently highly requested. Interestingly, the APC design has a lot more detail to it than other vehicles in the game and the developer mentioned other vehicles are also going to be improved:

  • Space Haven, the stylish spaceship colony sim is fully funded and heading to Linux

    Space Haven from Bugbyte, an exciting entry into the colony-building sim genre taking place on a spaceship has managed to get funded.

  • Wine-Staging 4.5 Comes In Smaller Thanks To More Patches Being Upstreamed

    While Wine-Staging 4.4 was at 770 patches compared to upstream Wine for running Windows programs/games on Linux and elsewhere, this weekend's Wine-Staging 4.5 is down to 759 patches thanks to more of these improvements being deemed ready for upstream.

    Wine-Staging 4.5 was released on Saturday night with 759 patches compared to the latest upstream code. This includes Wine-Staging still reverting the FAudio support for its XAudio2 implementation until more Linux distributions have begun packaging FAudio.

  • RISC-V Foundation Announces Agenda for Free, Half-Day Getting Started with RISC-V Events
  • A Weather Station Fit For A PDP-11

    The Digital Equipment Corp. PDP-11/70 is a masterpiece of Cold War-era industrial design. This microcomputer was the size of one or two modern server racks depending on configuration, and the front panel, loaded up with blinkenlights, was clad in a beautiful rose and magenta color scheme. The switches — the ones you used to toggle bits in memory — were actually custom designed covers made to match the shape of the completely unnecessary bezel. The aesthetic of the 11/70 is the intersection of baroque and modernism on the design Venn diagram.

    [Oscar Vermeulen] built a miniature version of the PDP-11/70 that houses a Raspberry Pi, and [rricharz] has been hard at work bringing an original copy of BSD to this system. The first great project to come out of this effort? It’s a weather station, and it’s exactly as cool as you think it is.

  • Daniel Stenberg: curl up 2019 is over

    (I will update this blog post with more links to videos and PDFs to presentations as they get published, so come back later in case your favorite isn’t linked already.)

    The third curl developers conference, curl up 2019, is how history. We gathered in the lovely Charles University in central Prague where we sat down in an excellent class room. After the HTTP symposium on the Friday, we spent the weekend to dive in deeper in protocols and curl details.

    I started off the Saturday by The state of the curl project (youtube). An overview of how we’re doing right now in terms of stats, graphs and numbers from different aspects and then something about what we’ve done the last year and a quick look at what’s not do good and what we could work on going forward.

Servers Leftovers

  • How Kubeflow is evolving without ksonnet

    Many software projects depend on modules that are run as separate open source projects. When one of those modules loses support (as is inevitable), the community around the main project must determine how to proceed.

    This situation is happening right now in the Kubeflow community. Kubeflow is an evolving open source platform for developing, orchestrating, deploying, and running scalable and portable machine learning workloads on Kubernetes. Recently, the primary supporter of the Kubeflow component ksonnet announced that it would no longer support the software.

    When a piece of software loses support, the decision-making process (and the outcome) differs greatly depending on whether the software is open source or closed source.

  • What is a honeypot? A trap for catching hackers in the act

    A honeypot is a trap that an IT pro lays for a malicious hacker, hoping that they'll interact with it in a way that provides useful intelligence. It's one of the oldest security measures in IT, but beware: luring hackers onto your network, even on an isolated system, can be a dangerous game.

    Norton's simple definition of a honeypot is a good starting place: "A honeypot is a computer or computer system intended to mimic likely targets of cyberattacks." Often a honeypot will be deliberately configured with known vulnerabilities in place to make a more tempting or obvious target for attackers. A honeypot won't contain production data or participate in legitimate traffic on your network — that's how you can tell anything happening within it is a result of an attack. If someone's stopping by, they're up to no good.

Linux Journal at 25

LWN.net - Pon, 04/01/2019 - 15:16
Linux Journal celebrates 25 years since it began publishing. "Most magazines have the life expectancy of a house plant. Such was the betting line for Linux Journal when it started in April 1994. Our budget was a shoestring. The closest our owner, SSC (Specialized System Consultants) came to the magazine business was with the reference cards it published for UNIX, C, VI, Java, Bash and so on."

KDE Connect and Android

tuxmachines.org - Pon, 04/01/2019 - 14:46

As most of you know KDE Connect has recently been removed from Google Play due to a policy violation with regard to our SMS and telephony features. While the public outcry helped to get it back in with all features remaining this is just yet another example of how new Android policies make it harder for us to maintain the level of quality and features you expect from KDE Connect. Android Oreo forced us to drop support for older Android versions and imposed restrictions on background services which force us to have an annoying persistent notification. It is to be expected that Google will further restrict background services which will impose more problems for us. With each new Android versions new restrictions and problems arise which we have to work around, if possible. For example, the upcoming Android Q imposes restrictions on accessing the phone’s clipboard. It is unclear whether the clipboard sync in it’s current form is feasible on Android Q. Those are just examples of the problems with the direction Android is moving towards.

Excellent Utilities: tmux – terminal multiplexer software

tuxmachines.org - Pon, 04/01/2019 - 10:23

This is the first in a new series highlighting best-of-breed utilities. We’ll be covering a wide range of utilities including tools that boost your productivity, help you manage your workflow, and lots more besides. For the first article, we’ll put tmux under the spotlight.

tmux is a “terminal multiplexer”. This application enables a number of terminals (or windows) to be created, accessed and controlled from a single screen.

tmux runs as a server-client system. A server is created automatically when necessary and holds a number of sessions, each of which may have a number of windows linked to it.The tmux server manages clients, sessions, windows and panes.

The time you spend context switching between an editor and your consoles can devour your productivity. Take control of your environment with tmux, a terminal multiplexer that you can tailor to your workflow.
