  • Percona Announces Tutorial Schedule for Seventh Annual Percona Live Open Source Database Conference
  • FSFE Assembly at 34C3: Wir taten was

    In December 2017, the Chaos Communication Congress moved for the first time onto the Messegelände Leipzig. The FSFE came along and as in recent years, our assembly attracted a lot of visitors. Together with EDRi, for the first time we have been setting up a cluster called “Rights & Freedoms” with our own stage for multiple sessions. Although there have been some organisational issues, this Cluster was a big success and during three days, it has been visited by thousands of people.

    I am happy to see the FSFE assembly again growing every year and having the possibility to bring our message of Software Freedom to the people at the Chaos Communication Congress. The CCC is Germany’s biggest annual meetup of hackers and political activists and is “considered one of the largest events of this kind, alongside the DEF CON in Las Vegas” (wikipedia).

  • a2k18 Hackathon preview: Syncookies coming to PF

    One eagerly anticipated item is the arrival of TCP syncookies (read: another important tool in your anti-DDoS toolset) in PF. Henning Brauer (henning@) added the code in a series of commits on February 6th, 2018, with this one containing the explanation

  • design notes on inline caches in guile

    Next, there are the arithmetic operators: addition, multiplication, and so on. Scheme's arithmetic is indeed polymorphic; the addition operator + can add any number of complex numbers, with a distinction between exact and inexact values. On a representation level, Guile has fixnums (small exact integers, no heap allocation), bignums (arbitrary-precision heap-allocated exact integers), fractions (exact ratios between integers), flonums (heap-allocated double-precision floating point numbers), and compnums (inexact complex numbers, internally a pair of doubles). Also in Guile, arithmetic operators are a "primitive generics", meaning that they can be extended to operate on new types at runtime via GOOPS.

  • The State of OpenJDK In Early 2018

    Oracle's Mark Reinhold spoke at last weekend's FOSDEM conference about the state of OpenJDK for open-source Java.

    Reinhold's presentation covered the bumpy OpenJDK 9 release and then a look ahead to their next six-month release cadence for future OpenJDK releases. He sought to relieve some who feared more frequent breakage and about the handling of new features/functionality in Java and more. Long story short, Oracle hopes for a smooth transition.

OSS Leftovers

  • Sunjun partners with Collabora to offer LibreOffice in the Cloud
  • Tackling the most important issue in a DevOps transformation
    You've been appointed the DevOps champion in your organisation: congratulations. So, what's the most important issue that you need to address?
  • PSBJ Innovator of the Year: Hacking cells at the Allen Institute
  • SUNY math professor makes the case for free and open educational resources
    The open educational resources (OER) movement has been gaining momentum over the past few years, as educators—from kindergarten classes to graduate schools—turn to free and open source educational content to counter the high cost of textbooks. Over the past year, the pace has accelerated. In 2017, OERs were a featured topic at the high-profile SXSW EDU Conference and Festival. Also last year, New York State generated a lot of excitement when it made an $8 million investment in developing OERs, with the goal of lowering the costs of college education in the state. David Usinski, a math and computer science professor and assistant chair of developmental education at the State University of New York's Erie Community College, is an advocate of OER content in the classroom. Before he joined SUNY Erie's staff in 2007, he spent a few years working for the Erie County public school system as a technology staff developer, training teachers how to infuse technology into the classroom.

Mozilla: Wireless Innovation for a Networked Society, New AirMozilla Audience Demo, Firefox Telemetry

  • Net Neutrality, NSF and Mozilla's WINS Challenge Winners, openSUSE Updates and More
    The National Science Foundation and Mozilla recently announced the first round of winners from their Wireless Innovation for a Networked Society (WINS) challenges—$2 million in prizes for "big ideas to connect the unconnected across the US". According to the press release, the winners "are building mesh networks, solar-powered Wi-Fi, and network infrastructure that fits inside a single backpack" and that the common denominator for all of them is "they're affordable, scalable, open-source and secure."
  • New AirMozilla Audience Demo
    The legacy AirMozilla platform will be decommissioned later this year. The reasons for the change are multiple; however, the urgency of the change is driven by deprecated support of both the complex back-end infrastructure by IT and the user interface by Firefox engineering teams in 2016. Additional reasons include a complex user workflow resulting in a poor user experience, no self-service model, poor usability metrics and a lack of integrated, required features.
  • Perplexing Graphs: The Case of the 0KB Virtual Memory Allocations
    Every Monday and Thursday around 3pm I check dev-telemetry-alerts to see if there have been any changes detected in the distribution of any of the 1500-or-so pieces of anonymous usage statistics we record in Firefox using Firefox Telemetry.

Games: All Walls Must Fall, Tales of Maj'Eyal

  • All Walls Must Fall, the quirky tech-noir tactics game, comes out of Early Access
    This isometric tactical RPG blends in sci-fi, a Cold War that never ended and lots of spirited action. It’s powered by Unreal Engine 4 and has good Linux support.
  • Non-Linux FOSS: Tales of Maj'Eyal
    I love gaming, but I have two main problems with being a gamer. First, I'm terrible at video games. Really. Second, I don't have the time to invest in order to increase my skills. So for me, a game that is easy to get started with while also providing an extensive gaming experience is key. It's also fairly rare. All the great games tend to have a horribly steep learning curve, and all the simple games seem to involve crushing candy. Thankfully, there are a few games like Tales of Maj'Eyal that are complex but with a really easy learning curve.

KDE and GNOME: KDE Discover, Okular, Librsvg, and Phone's UI Shell

  • This week in Discover, part 7
    The quest to make Discover the most-loved Linux app store continues at Warp 9 speed! You may laugh, but it’s happening! Mark my words, in a year Discover will be a beloved crown jewel of the KDE experience.
  • Okular gains some more JavaScript support
    With it we support recalculation of some fields based on others. An example that calculates sum, average, product, minimum and maximum of three numbers can be found in this youtube video.
  • Librsvg's continuous integration pipeline
    With the pre-built images, and caching of Rust artifacts, Jordan was able to reduce the time for the "test on every commit" builds from around 20 minutes, to little under 4 minutes in the current iteration. This will get even faster if the builds start using ccache and parallel builds from GNU make. Currently we have a problem in that tests are failing on 32-bit builds, and haven't had a chance to investigate the root cause. Hopefully we can add 32-bit jobs to the CI pipeline to catch this breakage as soon as possible.
  • Design report #3: designing the UI Shell, part 2
    Peter has been quite busy thinking about the most ergonomic mobile gestures and came up with a complete UI shell design. While the last design report was describing the design of the lock screen and the home screen, we will discuss here about navigating within the different features of the shell.
