Fedora: ppc64le, and GNOME Sessions

  • Why it's useful to use a deskop on ppc64le

    I want provide a short example what I've met in the past weeks when dog-fooding a ppc64le Fedora desktop environment on my OpenPOWER based Talos II. We have experienced segfaults coming from a smashed stack in some desktop components, although no one using the mainstream arches noticed them. The toolchain guys will be able to explain why eg. x86_64 is immune (or just lucky), but the problems were real issues in the projects' source code. The common denominator was an incorrect callback signature for GTK+ based apps, the callbacks expected different parameters than were passed by their callers. And this kind of inconsistency can't be found during compile time. IMHO it opens possibilities for some static analysis before producing the binaries by looking at the signal definitions in GTK+ and what functions/callbacks are then attached to them in the projects. Or for some AI that will analyze the crashes and look for the common pattern and recommend a solution. And what's the conclusion - as usually, heterogenity helps to improve quality Smile

  • Stories from the amazing world of #6

    In the dungeons bellow the-new-hotness island was impenetrable darkness. It looks like somebody tried to destroy every source of light. Only my own levitating fireball was shedding some light around. Damage was still visible on walls and furniture, but most of it is now repaired to function properly. I’m glad that you are here with me, otherwise it will be a scary experience. But you probably want to hear what happened.

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 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!
