  • gnome extensions

    In general when using Gnome I try and avoid extensions. Most of the ‘default’ setup is fine or I was able to get used to it and it works well enough. There are a few extensions I do use however for various reasons. All of these work with Wayland.

  • GNOME 3.22/KDE Plasma 5.8 release party in Brno

    Last Thursday, we organized a regular Linux Desktop Meetup in Brno and because two major desktop environments had had their releases recently we also added a release party to celebrate them.

    The meetup itself took place in the Red Hat Lab at FIT BUT (venue of GUADEC 2013) and it consisted of 4 talks. I spoke on new things in GNOME 3.22, our KDE developer Jan Grulich spoke on new things in Plasma 5.8, then Oliver Gutierrez spoke on Fleet Commander and the last talk was given by Lucie Karmova who is using Fedora as a desktop in a public organization and shared her experiences with the Linux desktop.

  • GNOME outreach flyer for local groups and events

    One of my very early contributions to GNOME was a flyer. FOSDEM 2014 was one of the first conferences I attended and with me I had brought printouts of this flyer which we handed out to people from the GNOME stand.

  • GNOME Shell and Mutter Get Ready for GNOME 3.22 Desktop's First Point Release

    The GNOME Project prepares to unleash the first of two point releases for their latest and most advanced GNOME 3 desktop environment, version 3.22.1, so they're currently updating various core components and applications.

    GNOME 3.22 was officially unveiled last month, on September 21, 2016, and it brought numerous interesting new features and improvements. The first point release, GNOME 3.22.1, should improve your GNOME 3.22 experience, as well as to fix some of those annoying issues and annoyance that you've reported lately.

  • This Week in GTK+ – 19
  • GTK+ 4.0 Toolkit Development Is Warming Up

    With GNOME/GTK+ 3.22 having been released at the end of September, developer focus is beginning to shift to GNOME 3.24 or in the case of GTK+ developers it's about GTK+ 4.0 development per the toolkit's new development process.

    GTK+ 4.0 was opened for development in Git a few days ago. While not any exciting changes have yet landed in Git master, this branch is prepping the removal of GTK 3.x deprecated APIs and this branch will remove the deprecated style API.

  • GTK+, version numbering, and long-term support

    GTK+ version 3.22 was released on September 21, bringing with it a range of improvements to Wayland support, gesture support for pressure-sensitive tablets, several new widgets, and more. The release also marks a turning point for how stable and development branches of the code will be maintained. Moving forward, the project is adopting a new scheme that allows it to designate certain stable releases for long-term support. The plan also breaks with past releases where version numbering is concerned, though the project is keen to downplay that change in favor of focusing on the support that stable releases will offer to downstream projects.

    The new release scheme was announced on September 1 in a Google+ post and an accompanying blog post written by Allan Day. The blog post explains more of the background issues that led up to the decision to adopt a new scheme.

  • Web Engines Hackfest 2016!

    It had great talks that will eventually end up in videos uploaded to the web site. We were amazed at the progress being made to Servo, including some performance results that blew our minds. We also discussed the next steps for WebKitGTK+, WebKit for Wayland (or WPE), our own Clutter wrapper to WebKitGTK+ which is used for the Apertis project, and much more.


    One of the main problems people reported was applications that use WebKitGTK+ not showing anything where the content was supposed to appear. It turns out the problem was caused by GTK+ not being able to create a GL context. If the system was simply not able to use GL there would be no problem: WebKit would then just disable accelerated compositing and things would work, albeit slower.

  • Sysprof Plans for 3.24

    The 3.24 cycle is just getting started, and I have a few plans for Sysprof to give us a more polished profiling experience in Builder. The details can be found on the mailing list.

    In particular, I’d love to land support for visualizers. I expect this to happen soon, since there is just a little bit more to work through to make that viable. This will enable us to get a more holistic view of performance and allow us to drill into callgraphs during a certain problematic period of the profile.

  • GNOME From Scratch Project

    This morning i got an email from Rafael Tavares about his new project, GFS (GNOME From Scratch), a personal project that makes possible to use GNOME on Slackware GNU/Linux operating system without systemd or wayland programs. The GFS project will attempt to bring GNOME 3.22 to Slackware Linux. This is the latest version of GNOME available at this moment.

  • WebRTC in WebKit/WPE

    For some time I worked at Igalia to enable WebRTC on WebKitForWayland or WPE for the Raspberry Pi 2.

    The goal was to have the WebKit WebRTC tests working for a demo. My fellow Igalian Alex was working on the platform itself in WebKit and assisting with some tuning for the Pi on WebKit but the main work needed to be done in OpenWebRTC.

Linux 4.8.4

I'm announcing the release of the 4.8.4 kernel. And yeah, sorry about the quicker releases, I'll be away tomorrow and as they seem to have passed all of the normal testing, I figured it would be better to get them out earlier instead of later. And I like releasing stuff on this date every year... All users of the 4.8 kernel series must upgrade.

Security News

  • Free tool protects PCs from master boot record attacks [Ed: UEFI has repeatedly been found to be both a detriment to security and enabler of Microsoft lock-in]
    Cisco's Talos team has developed an open-source tool that can protect the master boot record of Windows computers from modification by ransomware and other malicious attacks. The tool, called MBRFilter, functions as a signed system driver and puts the disk's sector 0 into a read-only state. It is available for both 32-bit and 64-bit Windows versions and its source code has been published on GitHub. The master boot record (MBR) consists of executable code that's stored in the first sector (sector 0) of a hard disk drive and launches the operating system's boot loader. The MBR also contains information about the disk's partitions and their file systems. Since the MBR code is executed before the OS itself, it can be abused by malware programs to increase their persistence and gain a head start before antivirus programs. Malware programs that infect the MBR to hide from antivirus programs have historically been known as bootkits -- boot-level rootkits. Microsoft attempted to solve the bootkit problem by implementing cryptographic verification of the bootloader in Windows 8 and later. This feature is known as Secure Boot and is based on the Unified Extensible Firmware Interface (UEFI) -- the modern BIOS.
  • DDOS Attack On Internet Infrastructure
    I hope somebody's paying attention. There's been another big DDOS attack, this time against the infrastructure of the Internet. It began at 7:10 a.m. EDT today against Dyn, a major DNS host, and was brought under control at 9:36 a.m. According to Gizmodo, which was the first to report the story, at least 40 sites were made unreachable to users on the US East Coast. Many of the sites affected are among the most trafficed on the web, and included CNN, Twitter, PayPal, Pinterest and Reddit to name a few. The developer community was also touched, as GitHub was also made unreachable. This event comes on the heels of a record breaking 620 Gbps DDOS attack about a month ago that brought down security expert Brian Krebs' website, KrebsonSecurity. In that attack, Krebs determined the attack had been launched by botnets that primarily utilized compromised IoT devices, and was seen by some as ushering in a new era of Internet security woes.
  • This Is Why Half the Internet Shut Down Today [Update: It’s Getting Worse]
    Twitter, Spotify and Reddit, and a huge swath of other websites were down or screwed up this morning. This was happening as hackers unleashed a large distributed denial of service (DDoS) attack on the servers of Dyn, a major DNS host. It’s probably safe to assume that the two situations are related.
  • Major DNS provider Dyn hit with DDoS attack
    Attacks against DNS provider Dyn continued into Friday afternoon. Shortly before noon, the company said it began "monitoring and mitigating a DDoS attack" against its Dyn Managed DNS infrastructure. The attack may also have impacted Managed DNS advanced service "with possible delays in monitoring."
  • What We Know About Friday’s Massive East Coast Internet Outage
    Friday morning is prime time for some casual news reading, tweeting, and general Internet browsing, but you may have had some trouble accessing your usual sites and services this morning and throughout the day, from Spotify and Reddit to the New York Times and even good ol’ For that, you can thank a distributed denial of service attack (DDoS) that took down a big chunk of the Internet for most of the Eastern seaboard. This morning’s attack started around 7 am ET and was aimed at Dyn, an Internet infrastructure company headquartered in New Hampshire. That first bout was resolved after about two hours; a second attack began just before noon. Dyn reported a third wave of attacks a little after 4 pm ET. In all cases, traffic to Dyn’s Internet directory servers throughout the US—primarily on the East Coast but later on the opposite end of the country as well—was stopped by a flood of malicious requests from tens of millions of IP addresses disrupting the system. Late in the day, Dyn described the events as a “very sophisticated and complex attack.” Still ongoing, the situation is a definite reminder of the fragility of the web, and the power of the forces that aim to disrupt it.
  • Either IoT will be secure or the internet will be crippled forever
    First things first a disclaimer. I neither like nor trust the National Security Agency (NSA). I believe them to be mainly engaged in economic spying for the corporate American empire. Glenn Greenwald has clearly proven that in his book No Place to Hide. At the NSA, profit and power come first and I have no fucking clue as to how high they prioritize national security. Having said that, the NSA should hack the Internet of (insecure) Things (IoT) to death. I know Homeland Security and the FBI are investigating where the DDoS of doomsday proportions is coming from and the commentariat is already screaming RUSSIA! But it is really no secret what is enabling this clusterfuck. It’s the Mirai botnet. If you buy a “smart camera” from the Chinese company Hangzhou XiongMai Technologies and do not change the default password, it will be part of a botnet five minutes after you connect it to the internet. We were promised a future where we would have flying cars but we’re living in a future where camera’s, light-bulbs, doorbells and fridges can get you in serious trouble because your home appliances are breaking the law.
  • IoT at the Network Edge
    Fog computing, also known as fog networking, is a decentralized computing infrastructure. Computing resources and application services are distributed in logical, efficient places at any points along the connection from the data source (endpoint) to the cloud. The concept is to process data locally and then use the network for communicating with other resources for further processing and analysis. Data could be sent to a data center or a cloud service. A worthwhile reference published by Cisco is the white paper, "Fog Computing and the Internet of Things: Extend the Cloud to Where the Things Are."

With the release of Linux 4.0, users have been able to update their kernel packages without rebooting, however, Ubuntu will be the first distribution to offer this feature for free.
  • ​The Dirty Cow Linux bug: A silly name for a serious problem
    Dirty Cow is a silly name, but it's a serious Linux kernel problem. According to the Red Hat bug report, "a race condition was found in the way the Linux kernel's memory subsystem handled the copy-on-write (COW) breakage of private read-only memory mappings. An unprivileged local user could use this flaw to gain write access to otherwise read-only memory mappings and thus increase their privileges on the system."
