Screencasting with OBS Studio on Wayland

Filed under
Software
GNOME

For the past few months, I’ve been doing live coding sessions on YouTube showing how GNOME development goes. Usually it’s a pair of sessions per week, one in Brazilian Portuguese so that my beloved community can enjoy GNOME in their native language; and one in English, to give other people at least a chance to follow development as well.

We are quite lucky to have OBS Studio available for screencasting and streaming, as it makes our lives a lot easier. It’s really a fantastic application. I learned about it while browsing Flathub, and it’s what actually motivated me to start streaming in the first place. However, I have to switch to X11 in order to use it, since the GNOME screencast plugin never really worked for me.

This is annoying since Mutter supports screencasting for years now, and I really want to showcase the latest and greatest while streaming. We’re still not using the appropriate APIs and methods to screencast, which doesn’t set a high standard on the community.

So I decided to get my hands dirty, bite the bullet, and fix this situation. And so was born the obs-xdg-portal plugin for OBS Studio! The plugin uses the standard ScreenCast portal, which means it should work inside and outside the Flatpak sandbox, in Wayland and X11, and on GNOME and KDE (and perhaps others?).

KDE
Software
Ubuntu

Simplicity is the magic ingredient in any product design. For members of the KDE community, snap development has become that much simpler, thanks to the recent introduction of the KDE neon extension.

Last year, we talked about the KDE build and content snaps, which can greatly speed the build of KDE application snaps and save disk space. The extension takes this effort one step farther, and allows for faster, smoother integration of snaps into the Linux desktop. While there are no shortcuts in life, you can rely on a passionate community of skilled techies to make the journey easier.

  • Google's Stadia Game Streaming Service Arrives To A Collective 'Meh'

    As we noted last week, there's a laundry list of potential issues plaguing Google's attempted entry into the game streaming space via Google Stadia, not least of which is the US' substandard broadband networks and arbitrary broadband caps. Stadia eliminates the physical home game console and instead moves all game processing to the cloud. And while it's clear that this is the inevitable path forward and somebody is going to eventually dominate the space, there's no solid indication yet that it's going to be Google.

  • Security lessons from a Mac-only fintech company

    Apple remains a highly secure choice for enterprise professionals, but security threats remain and the environment requires sophisticated endpoint management tools, according to Build America Mutual (BAM) CTO David McIntyre.

  • Trump is lying about the ‘new’ ‘Apple’ factory

    This is not true for a couple reasons — one of them nitpicky and one of them a lot more serious. The nitpicky problem is that Apple isn’t actually building a manufacturing plant. The company is building a new campus in Austin, but it’s miles away from the factory and the jobs are going to be very similar to the kind of white-collar design and engineering work that Apple does in Cupertino. Apple doesn’t do its own manufacturing, and the plant Trump is standing in belongs to a contractor called Flex Ltd (formerly Flextronics).

    But the bigger problem is that what Flex is doing isn’t anything new. This particular factory has been manufacturing Mac Pros since 2013, when Cook first announced it would assemble them in the United States. That’s before Trump took office. So the idea that we’re seeing the beginning of something, or that Trump has done something during his presidency to bring about this particular instance of US manufacturing, just doesn’t hold water.

    Trump is talking as if Apple has created a brand-new factory in Texas to build Mac Pros. If all you saw was a five-second clip on the news, that’s probably the impression you would get — but it just isn’t true.

  • SaltStack adds automatic vulnerability remediation tool to portfolio

    IT automation tool provider SaltStack has kicked off its SecOps division by announcing the general availability of SaltStack Protect.

    Protect is meant to make the “massive amount of coordination and work required to actually fix thousands of infrastructure security vulnerabilities” less daunting, by throwing some automation into the mix.

    To do that, the product ingests vendor CVE advisories and delivers scans and remediation workflows as a service to SaltStack customers. Automatic prioritisation of which issues to tackle first can be realised by feeding the system with real-time data on the configuration state of all assets in a SaltStack environment, which ties it in with the rest of the SaltStack portfolio.

Krita 4.2.8 Beta

Filed under
KDE
Software

We had to skip the October release because we were working on a bunch of issues that took longer to resolve than planned, but that means that this release has more fixes than ever. Please test this beta, and take the survey afterwards!

There has been a lot of work on vector shapes, the transform tool and, especially, saving on Windows. Windows usually only writes out saved files to the actual disk when it feels like it.

So if you’d cut the power to your computer before Windows did that, you might get corrupted files. With 1,500,000 distinct Windows 10 users of Kritain the past month, chances are good for that happening (just like there are people who work exclusively with unnamed autosave files — don’t do that!), so we now try to force Windows to write files to disk after saving.

  • DXVK 1.4.5 released bringing further performance improvements for D3D11 and D3D10 to Vulkan

    DXVK continues maturing with another exciting sounding release now available with DXVK 1.4.5, bringing in some performance improvements and plenty of bug fixes.

    On the performance side DXVK 1.4.5 now enables asynchronous presentation on all GPUs, which was previously disabled for NVIDIA due to GPU hangs. You should ensure your driver is fully up to date, and try the NVIDIA Vulkan Beta Driver as well. On top of that, this release has a reduction in the amount of thread synchronization around occlusion queries which should improve multithreading efficiency.

  • DXVK 1.4.5 Brings Async Presentation For All GPUs, Better Multi-Threading Efficiency

    It's been three weeks already since the last DXVK update but that was succeeded this evening by DXVK 1.4.5 as another notable update to this project mapping Direct3D 10/11 onto Vulkan for speeding up the Wine/Proton-based Windows gaming experience on Linux.

    DXVK 1.4.5 unconditionally enables asynchronous presentation now for all GPUs while dropping the "asyncPresent" tunable previously exposed for toggling this behavior. For those particularly on NVIDIA graphics if encountering any GPU hangs, make sure you are running the latest NVIDIA driver.

Proprietary: CrossOver 19, ycrash and SUSE Pushing HANA

  • CROSSOVER 19 IS PROGRESSING WELL AND IS NOW IN BETA!

    It's been two weeks; we feel we owe everyone an update on our efforts to support 32 bit Windows applications on macOS Catalina, despite Apple's decision to terminate support for 32 bit applications.

    I'm happy to announce that we have released the first beta version of CrossOver 19 on Friday, November 15, 2019 to our community of advocates and beta testers. Further, our alpha testing and other internal testing has gone well, so I am confident that we will have a final product ready before the end of the year.

  • CrossOver 19 Enters Beta With Better Microsoft Office Support On Linux

    CodeWeavers' Jeremy White has announced that CrossOver 19 is now in beta for existing customers of this Wine-based software for running Windows programs on Linux and macOS.

    The biggest benefactor of CrossOver 19 is Apple macOS users with there being initial support for macOS Catalina. CrossOver/Wine needed a lot of changes to enable support for this newest version of macOS particularly for 32-bit Windows programs with Apple aiming to end 32-bit application support on their operating system.

  • Overview of ycrash – finding the source of your problem

    Take a tour of ycrash in this article by Ram Lakshmanan. ycrash helps capture critical artifacts, including garbage collection logs, thread dumps, core dumps, heap dumps, disk usage, and more when the problem happens. It applies machine learning algorithms and generates a report which gives you a complete view of the problem, down to the lines of code that caused it.
    The industry has seen cutting edge application performance monitoring tools (AppDynamics, NewRelic, Dynatrace…), log analysis tools (DataDog, Splunk,…). These are great tools for detecting problems. i.e. they can detect CPU spiked by x%, memory degraded by y%, response time shot up by z seconds. But they don’t answer the question: Why has the CPU spiked up? Why has memory degraded? Why has the response time increased? You still need to engage developers/architects/vendors to troubleshoot the problem and identify the root cause of the problem.

    ycrash captures critical artifacts (GC logs, thread dumps, core dumps, heap dumps, netstat, vmstat, lsof, iostat, top, disk usage….) when the problem happens, applies machine learning algorithms, and generates one unified root cause analysis report. This report gives you a 360-degree view of the problem. The report points out the exact class, method, and line of code that caused the problem.
