  • Women in IT Awards USA winner: Margaret Dawson, Red Hat

    Margaret has led teams at companies ranging from startups to Fortune 500 firms including Amazon, Microsoft and HP. She grew up in Detroit and began her career in the automotive industry, an experience that helped her feel at home in the similarly male-dominated technology sector.

    She has a passion for mentoring women in technology and has made it her mission to share the lessons she has learned with others and to mentor them in their own journeys.

  • How do tools affect culture?

    Most of the DevOps community talks about how tools don’t matter much. The culture has to change first, the argument goes, which might modify how the tools are used.

    I agree and disagree with that concept. I believe the relationship between tools and culture is more symbiotic and bidirectional than unidirectional. I have discovered this through real-world transformations across several companies now. I admit it’s hard to determine whether the tools changed the culture or whether the culture changed how the tools were used.

  • GPU Accelerated SQL queries with PostgreSQL & PG-Strom in OpenShift-3.10

    In the OpenShift 3.9 GPU blog, we leveraged machine learning frameworks on OpenShift for image recognition. And in the How To Use GPUs with DevicePlugin in OpenShift 3.10 blog, we installed and configured an OpenShift cluster with GPU support. In this installment, we will create a more sophisticated workload on the cluster – accelerating databases using GPUs.

    One of the key parts of any machine learning algorithm is the data (often referred to as the data lake/warehouse, stored as structured, semi-structured or unstructured data).

    A major part of machine learning pipelines is the preparation, cleaning, and exploration of this data. Specifically removing NAs (missing values), transformations, normalization, subsetting, sorting, and a lot of plotting.

  • Reducing the use of non-glibc allocators in Fedora

    Memory allocation for applications is a bit of a balancing act between various factors including CPU performance, memory efficiency, and how the memory is actually being allocated and deallocated by the application. Different programs may have diverse needs, but it is often the kind of workload that the application is expected to handle that determines which memory allocator performs best. That argues for a diversity of memory allocators (and allocation strategies) but, on the other hand, that complicates things for Linux distributions. As a result, Fedora is discussing ways to rein in the spread of allocators used by its packages.

  • Copr has a brand new API

    New Copr version is here and after several months of discussions and development, it finally brings a brand new API. In this article, we are going to see why it was needed, how it is better than previous API versions (i.e. why you should be happy about it) and try some code samples.

Opening Files with Qt on Android

After addressing Android support in KF5Notifications another fairly generic task that so far required Android specific code is next: opening files. Due to the security isolation of apps and the way the native “file dialog” works on Android this is quite different from other platforms, which makes application code a bit ugly. This can be fixed in Qt though. Read more

Ubuntu-Centric Full Circle Magazine and Debian on the Raspberryscape

  • Full Circle Magazine: Full Circle Weekly News #121
  • Debian on the Raspberryscape: Great news!
    I already mentioned here having adopted and updated the Raspberry Pi 3 Debian Buster Unofficial Preview image generation project. As you might know, the hardware differences between the three families are quite deep ? The original Raspberry Pi (models A and B), as well as the Zero and Zero W, are ARMv6 (which, in Debian-speak, belong to the armel architecture, a.k.a. EABI / Embedded ABI). Raspberry Pi 2 is an ARMv7 (so, we call it armhf or ARM hard-float, as it does support floating point instructions). Finally, the Raspberry Pi 3 is an ARMv8-A (in Debian it corresponds to the ARM64 architecture). [...] As for the little guy, the Zero that sits atop them, I only have to upload a new version of raspberry3-firmware built also for armel. I will add to it the needed devicetree files. I have to check with the release-team members if it would be possible to rename the package to simply raspberry-firmware (as it's no longer v3-specific). Why is this relevant? Well, the Raspberry Pi is by far the most popular ARM machine ever. It is a board people love playing with. It is the base for many, many, many projects. And now, finally, it can run with straight Debian! And, of course, if you don't trust me providing clean images, you can prepare them by yourself, trusting the same distribution you have come to trust and love over the years.

OSS: SVT-AV1, LibreOffice, FSF and Software Freedom Conservancy

  • SVT-AV1 Already Seeing Nice Performance Improvements Since Open-Sourcing
    It was just a few weeks ago that Intel open-sourced the SVT-AV1 project as a CPU-based AV1 video encoder. In the short time since publishing it, there's already been some significant performance improvements.  Since the start of the month, SVT-AV1 has added multi-threaded CDEF search, more AVX optimizations, and other improvements to this fast evolving AV1 encoder. With having updated the test profile against the latest state as of today, here's a quick look at the performance of this Intel open-source AV1 video encoder.

  • What I learned during my internship with the FSF tech team
    Hello everyone, I am Hrishikesh, and this is my follow-up blog post concluding my experiences and the work I did during my 3.5 month remote internship with the FSF. During my internship, I worked with the tech team to research and propose replacements for their network monitoring infrastructure. A few things did not go quite as planned, but a lot of good things that I did not plan happened along the way. For example, I planned to work on GNU LibreJS, but never could find enough time for it. On the other hand, I gained a lot of system administration experience by reading IRC conversations, and by working on my project. I even got to have a brief conversation with RMS! My mentors, Ian, Andrew, and Ruben, were extremely helpful and understanding throughout my internship. As someone who previously had not worked with a team, I learned a lot about teamwork. Aside from IRC, we interacted weekly in a conference call via phone, and used the FSF's Etherpad instance for live collaborative editing, to take notes. The first two months were mostly spent studying the FSF's existing Nagios- and Munin-based monitoring and alert system, to understand how it works. The tech team provided two VMs for experimenting with Prometheus and Nagios, which I used throughout the internship. During this time, I also spent a lot of time reading about licenses, and other posts about free software published by the FSF.
