  • Google to Abandon Tablets in Favor of Chrome OS Laptops

    One reason that Google is moving away from tablets has to do with the fact that they are just not selling all that well.

  • Support for Jupyter notebooks has evolved in Cantor

    Hello everyone, it's been almost a month since my last post and there are a lot of changes that have been done since then.

    First, what I called the "minimal plan" is arleady done! Cantor can now load Jupyter notebooks and save the currently opened document in Jupyter format.

    Below you can see how one of the Jypiter notebooks I'm using for test purposes (I have mentioned them in previous post) looks in Jupyter and in Cantor.

  • Will Thompson: Rebasing downstream translations

    At Endless, we maintain downstream translations for an number of GNOME projects, such as gnome-software, gnome-control-center and gnome-initial-setup. 

    [...]

    Whenever we update to a new version of GNOME, we have to reconcile our downstream translations with the changes from upstream. We want to preserve our intentional downstream changes, and keep our translations for strings that don’t exist upstream; but we also want to pull in translations for new upstream strings, as well as improved translations for existing strings. Earlier this year, the translation-rebase baton was passed to me. My predecessor would manually reapply our downstream changes for a set of officially-supported languages, but unlike him, I can pretty much only speak English, so I needed something a bit more mechanical.

    I spoke to various people from other distros about this problem.1 A common piece of advice was to not maintain downstream translation changes: appealing, but not really an option at the moment. I also heard that Ubuntu follows a straightforward rule: once the translation for a string has been changed downstream, all future upstream changes to the translation for that string are ignored. The assumption is that all downstream changes to a translation must have been made for a reason, and should be preserved. This is essentially a superset of what we’ve done manually in the past.

    I wrote a little tool to implement this logic, pomerge. Its “rebase” mode takes the last common upstream ancestor, the last downstream commit, and a working copy with the newest downstream code. For each locale, for each string in the translation in the working copy, it compares the old upstream and downstream translations – if they differ, it merges the latter into the working copy.

  • GNOME 3.33.3 Released, Kernel Security Updates for RHEL and CentOS, Wine Developers Concerned with Ubuntu 19.10 Dropping 32-Bit Support, Bzip2 to Get an Update and OpenMandriva Lx 4.0 Now Available

    GNOME 3.33.3 was released yesterday. Note that this release is development code and is intended for testing purposes.

  • TenFourFox FPR15b1 available

    In honour of New Coke's temporary return to the market (by the way, I say it tastes like Pepsi and my father says it tastes like RC), I failed again with this release to get some sort of async/await support off the ground, and we are still plagued by issue 533. The second should be possible to fix, but I don't know exactly what's wrong. The first is not possible to fix without major changes because it reaches up into the browser event loop, but should be still able to get parsing and thus enable at least partial functionality from the sites that depend on it. That part didn't work either. A smaller hack, though, did make it into this release with test changes. Its semantics aren't quite right, but they're good enough for what requires it and does fix some parts of Github and other sites.

  • Cloudflare's random number generator, robotics data visualization, npm token scanning, and more news

    Is there such a thing as a truly random number? Internet security and services provider Cloudflare things so. To prove it, the company has formed The League of Entropy, an open source project to create a generator for random numbers.

    The League consists of Cloudflare and "five other organisations — predominantly universities and security companies." They share random numbers, using an open source tool called Drand (short for Distributed Randomness Beacon Daemon). The numbers are then "composited into one random number" on the basis that "several random numbers are more random than one random number." While the League's random number generator isn't intended "for any kind of password or cryptographic seed generation," Cloudflare's CEO Matthew Prince points out that if "you need a way of having a known random source, this is a really valuable tool."

Kernel: Systemd 243 and Linux 5.3

  • Systemd 243 Is Getting Buttoned Up For Release With New Features & Fixes

    While it would have been nice seeing this next systemd release sooner due to the Zen 2 + RdRand issue with systemd yielding an unbootable system (that is now also being worked around with a BIOS upgrade), the systemd 243 release looks like it will take place in the near future.

  • VIRTIO-IOMMU Driver Merged For Linux 5.3 Kernel

    With the VirtIO standard for cross-hypervisor compatibility of different virtualized components there is a virtual IOMMU device that is now backed by a working driver in the Linux 5.3 kernel. The VirtIO specification provides for a virtual IOMMU device as of the v0.8 specification that is platform agnostic and manages direct memory accesses from emulated or physical devices in an efficient manner.

  • Linux Kernel Looks To Remove 32-bit Xen PV Guest Support

    Coming soon to a kernel near you could be the removal of 32-bit Xen PV guest support as better jiving with Xen's architectural improvements and more of the Linux/open-source community continuing to shift focus to 64-bit x86 with trying to finally sunset 32-bit x86.

Google, Money and Censorship in Free Software communities

Alexander Wirt (formorer) has tried to justify censoring the mailing list in various ways. Wirt is also one of Debian's GSoC administrators and mentors, it appears he has a massive conflict of interest when censoring posts about Google. Wirt has also made public threats to censor other discussions, for example, the DebConf Israel debate. The challenges of holding a successful event in that particular region require a far more mature approach. Why are these donations and conflicts of interest hidden from the free software community who rely on, interact with contribute to Debian in so many ways? Why doesn't Debian provide a level playing field, why does money from Google get this veil of secrecy? [...] Google also operates a mailing list for mentors in Google Summer of Code. It looks a lot like any other free software community mailing list except for one thing: censorship. Look through the "Received" headers of messages on the mailing list and you can find examples of messages that were delayed for some hours waiting for approval. It is not clear how many messages were silently censored, never appearing at all. Recent attempts to discuss the issue on Google's own mailing list produced an unsurprising result: more censorship.

IBM, Red Hat and Fedora Leftovers

  • OpenShift 4: Image Builds

    One of the key differentiators of Red Hat OpenShift as a Kubernetes distribution is the ability to build container images using the platform via first class APIs. This means there is no separate infrastructure or manual build processes required to create images that will be run on the platform. Instead, the same infrastructure can be used to produce the images and run them. For developers, this means one less barrier to getting their code deployed. With OpenShift 4, we have significantly redesigned how this build infrastructure works. Before that sets off alarm bells, I should emphasize that for a consumer of the build APIs and resulting images, the experience is nearly identical. What has changed is what happens under the covers when a build is executed and source code is turned into a runnable image.

  • libinput's new thumb detection code

    The average user has approximately one thumb per hand. That thumb comes in handy for a number of touchpad interactions. For example, moving the cursor with the index finger and clicking a button with the thumb. On so-called Clickpads we don't have separate buttons though. The touchpad itself acts as a button and software decides whether it's a left, right, or middle click by counting fingers and/or finger locations. Hence the need for thumb detection, because you may have two fingers on the touchpad (usually right click) but if those are the index and thumb, then really, it's just a single finger click. libinput has had some thumb detection since the early days when we were still hand-carving bits with stone tools. But it was quite simplistic, as the old documentation illustrates: two zones on the touchpad, a touch started in the lower zone was always a thumb. Where a touch started in the upper thumb area, a timeout and movement thresholds would decide whether it was a thumb. Internally, the thumb states were, Schrödinger-esque, "NO", "YES", and "MAYBE". On top of that, we also had speed-based thumb detection - where a finger was moving fast enough, a new touch would always default to being a thumb. On the grounds that you have no business dropping fingers in the middle of a fast interaction. Such a simplistic approach worked well enough for a bunch of use-cases but failed gloriously in other cases.

  • 21 to 1: How Red Hat amplifies partner revenue

    At Red Hat Summit, we announced new research from IDC looking at the contributions of Red Hat Enterprise Linux (RHEL) to the global economy. The study, sponsored by Red Hat, found that the workloads running on Red Hat Enterprise Linux are expected to "touch" more than $10 trillion worth of global business revenues in 2019 - powering roughly 5% of the worldwide economy. While that statistic alone is eye popping, these numbers, according to the report, are only expected to grow in the coming years, fueled by more organizations embracing hybrid cloud infrastructures. As a result, there is immense opportunity for Red Hat partners and potential partners to capitalize on the growth and power of RHEL.

  • The NeuroFedora Blog: NEURON in NeuroFedora needs testing

    We have been working on including the NEURON simulator in NeuroFedora for a while now. The build process that NEURON uses has certain peculiarities that make it a little harder to build. For those that are interested in the technical details, while the main NEURON core is built using the standard ./configure; make ; make install process that cleanly differentiates the "build" and "install" phases, the Python bits are built as a "post-install hook". That is to say, they are built after the other bits in the "install" step instead of the "build" step. This implies that the build is not quite straightforward and must be slightly tweaked to ensure that the Fedora packaging guidelines are met.

Software: Genome Browsers, EtherCalc and Curl

  • Best Free Web Based Genome Browsers

    In the fields of molecular biology and genetics, a genome is the genetic material of an organism. It consists of DNA (or RNA in RNA viruses). Each genome contains all of the information needed to build and maintain that organism. In humans, a copy of the entire genome—more than 3 billion DNA base pairs—is contained in all cells that have a nucleus. The study of the genome is called genomics. In bioinformatics, a genome browser is a graphical interface for display of information from a biological database for genomic data. They are important tools for studying genomes given the vast amounts of data available. They typically load very large files, such as whole genome FASTA files and display them in a way that users can make sense of the information there. They can be used to visualize a variety of different data types. Genome browsers enable researchers to visualize and browse entire genomes with annotated data including gene prediction and structure, proteins, expression, regulation, variation, comparative analysis, etc. They use a visual, high-level overview of complex data in a form that can be grasped at a glance and provide the means to explore the data in increasing resolution from megabase scales down to the level of individual elements of the DNA sequence. There’s a wide range of web based genome browsers. We’re going to restrict our selection to the top 4.

  • Daniel Stenberg: curl 7.65.2 fixes even more

    Six weeks after our previous bug-fix release, we ship a second release in a row with nothing but bug-fixes. We call it 7.65.2. We decided to go through this full release cycle with a focus on fixing bugs (and not merge any new features) since even after 7.65.1 shipped as a bug-fix only release we still seemed to get reports indicating problems we wanted fixed once and for all. Download curl from curl.haxx.se as always! Also, I personally had a vacation already planned to happen during this period (and I did) so it worked out pretty good to take this cycle as a slightly calmer one. Of the numbers below, we can especially celebrate that we’ve now received code commits by more than 700 persons!
