  • NVIDIA DP MST Audio To Begin Working With The Linux 5.5 Kernel

    While the official NVIDIA Linux driver has worked well with DisplayPort Multi-Stream Transport (DP MST) setups for years now for driving large displays, audio hasn't worked under Linux for NVIDIA's driver in this combination. But with the upcoming Linux 5.5 cycle that will be addressed.

  • Fedora Update Weeks 39–45

    Somehow, my semi-weekly updates turned into monthly things. Mostly, updates per week have been rather light and stable, so it always seemed that there was no need to write an update. Of course, that ends up meaning one really large update after a long time. This past week was pretty busy, so I thought it best to finally write up a post. One small changeset was removing automated Suggests from R packages when they do not exist in Fedora yet. This is due to legal concerns on the F31 Change for automated R dependencies. So far, I’ve fixed mine, and intend to fix others’ soon. On the Python 2 front, aside from dropping unused subpackages from Fedora 32, I’ve also ported git-cinnabar’s test running from nose to unittest. This makes it easier to get the Python 2 exception. Since upstream is working on Python 3 support, I expect that this exception won’t need to be in place for long.

  • Zekr Quran (1.1.0 Final) on linux (Fedora 30)

    It work fine on Java 6 era but not anymore. You need to tweak, hack, compile you self or find package alternative. I want to build this software as RPM package so it will be available for others but maybe it will take lot of effort.. plus there is issue about licensing, humm.. maybe next time? Anyway, If you are looking for solution how to install Zekr on Fedora, just let me know. I will help.

  • Mozilla Localization (L10N): L10n Report: November Edition

    As anticipated in previous reports, the release cycles are getting progressively shorter, in order to reach a consistent 4 weeks length in the first half of 2020. Firefox 71 will be released next week, on December 3rd. At that point Firefox 72 will move to beta, and the deadline to ship updates for that version will be on December 24th. Firefox 71 will ship with 3 new languages: Catalan (Valencian) (ca-valencia), Tagalog (tl), and Triqui (trs).

  • Better math import from PPTX into Impress

    Impress now has a much improved math handling in its importer from PPTX, eliminating annoying duplicated objects you had to delete after import, manually. First, thanks TU Dresden who made this work by Collabora possible.

Programming Leftovers

  • Faster Winter 4: Export lists

    Without an export, the compiler has to assume that every top-level function can possibly called from the outside, even functions that you think of as “internal”. If you have a function that you do not export, like instr, step_work and step after my change, the compiler can see all the places the function is called. If the function is only called in one place, it may inline it (copy its definition into where it is called), and simplify the code around the edges. And even if it does not inline the function, it might learn something about how the functions are used, and optimize them based on that (e.g. based on Demand Analysis).

  • Ondřej Holý: How to call asynchronous function synchronously

    GLib provides a lot of asynchronous functions, especially to deal with I/O. Unfortunately, some functions don’t have synchronous equivalents and the code has to be split into several callbacks. This is not handy in some cases. My this year’s GSoC student recently asked me whether it is possible to create synchronous function from asynchronous. He is currently working on test suite and don’t want to split test cases into several callbacks. So I decided to write a blog spot about as it might be handy for more people.

  • Sort list alphabetically with python

    You will be given a vector of string(s). You must sort it alphabetically (case-sensitive!!) and then return the first value. The returned value must be a string and have “***” between each of its letters. You should not remove or add elements from/to the array. Above is another problem in codewars, besides asking us to sort the array list and returning the first value in that list, we also need to insert stars within the characters.

  • Abolishing SyntaxError: invalid syntax ...

    Do you remember when you first started programming (possibly with Python) and encountered an error message that completely baffled you? For some reason, perhaps because you were required to complete a formal course or because you were naturally persistent, you didn't let such messages discourage you entirely and you persevered. And now, whenever you see such cryptic error messages, you can almost immediately decipher them and figure out what causes them and fix the problem. Congratulations, you are part of an elite group! Even a large number of people who claim that they can program are almost certainly less capable than you are. Given your good fortune, would you mind donating 5 to 10 minutes of your time to help countless beginners that are struggling in trying to understand Python error messages?

  • Is it too late to integrate GitOps?

    The idiom “missed the boat” can be used to describe the loss of an opportunity or a chance to do something. With OpenShift, the excitement to use this new and cool product immediately may create your own “missed the boat” moment in regards to managing and maintaining deployments, routes, and other OpenShift objects but what if the opportunity isn’t completely gone? Continuing with our series on GitOps (LINK), the following article will walk through the process of migrating an application and its resources that were created manually to a process in which a GitOps tool manages the assets. To help us understand the process we will manually deploy a httpd application. Using the steps below we will create a namespace, deployment, and service and expose the service which will create a route.

Canonical Teases Big Ubuntu Announcement with Leading Global Automation Company

Canonical, the company behind the popular Ubuntu Linux operating system, announced today that it will be present at the upcoming Smart Product Solutions (SPS) 2019 event in Nuremberg to showcase Ubuntu Core to the industrial Mittelstand. Canonical continues to promote its Ubuntu Core operating system, a slimmed-down version of Ubuntu designed and optimized to run on smaller, embedded hardware, such as IoT (Internet of Things) devices, and it now promises to support the Mittelstand innovators, which are medium-sized companies, with Open Source software and GNU/Linux technologies.
