  • Linux Professional Institute (LPI) transforming to a membership-based organisation

    LPI's goals over the years has been to help steer careers and entrepreneurship by proving the skills of practitioners working with open source software. Its focus has been on Linux distribution neutrality, training methods, and promoting open source.

    Under the new arrangement, certification holders will soon be able to become LPI members, which means they will have the ability to elect the LPI Board of Directors and steer the direction of the organisation.

  • Reproducible Builds: Weekly report #199

    strip-nondeterminism is our tool that post-processes files to remove known non-deterministic output. This week, Chris Lamb adjusted its behaviour to deduplicate hardlinks via stat(2) before processing to avoid issues when handling files in parallel; as the per-filetype handlers are yet currently guaranteed to be atomic, one process could temporarily truncate a file which can cause errors in other processes operating on the “same” file under a different pathname. This was thus causing package build failures in packages that de-duplicate hardlinks in their build process such as the Debian Administrator’s Handbook (#922168).

Using Clear Linux As A Desktop Linux Distribution - It Works Well But With Some "Papercuts"

Phoronix - Tor, 02/19/2019 - 16:00
While I am a big fan of Intel's Clear Linux distribution for its raw performance on x86_64 hardware that for most workloads goes unsurpassed by any other Linux platform out-of-the-box, there has been a lot of Phoronix readers wondering how well it could function as a standard desktop Linux distribution. With upgrading my main production system earlier this month, I decided to try out Clear Linux and now with 200+ hours into using it as the OS on my main production system, I figured it'd be good to share my initial thoughts.

Programming: CRuby, C++, R, Qt, LSP/Python, and C

tuxmachines.org - Tor, 02/19/2019 - 15:53
  • Register Transfer Language for CRuby

    For the last two years, I have been trying to improve CRuby performance. I have been working simultaneously on two major fronts: introducing register transfer language (RTL) for the CRuby virtual machine (VM) and just-in-time (JIT) compilation. For background on the goal of having Ruby 3 be 3 times faster than version 2 (3X3), see my previous article, “Towards the Ruby 3×3 Performance Goal“.

    The JIT project (MJIT) is advancing successfully. The JIT approach and engine I proposed and implemented has been adopted by the CRuby community. Takashi Kokubun hardened the code and adapted it to the current CRuby stack machine and recently MJIT became an experimental feature of the CRuby 2.6 release.

    Introducing a Register Transfer Language (RTL) to the CRuby VM turned out to be an even harder task than introducing the initial JIT compiler. The required changes to the VM are far more invasive than the ones needed for the JIT compiler.

  • Template meta-programming: Some testing and debugging tricks

    There are only a few things more fun in this world than doing template meta-programming (TMP) and reading all those long poems that the compiler writes out when we make even the smallest mistake.

    While we don’t usually welcome these messages, there are ways to make them useful.

    One of the main causes of errors in TMP code are unexpected types – types that the compiler is deducing instead of the types that we expect it to deduce.

    This results in error messages occurring in seemingly random places in our code.

  • Open Science, Open Source and R

    Psychology changed forever on the August 27, 2015. For the previous four years, the 270 psychologists of the Open Science Collaboration had been quietly re-running 100 published psychology experiments. Now, finally, they were ready to share their findings. The results were shocking. Less than half of the re-run experiments had worked.

    When someone tries to re-run an experiment, and it doesn't work, we call this a failure to replicate. Scientists had known about failures to replicate for a while, but it was only quite recently that the extent of the problem became apparent. Now, an almost existential crisis loomed. That crisis even gained a name: the Replication Crisis. Soon, people started asking the same questions about other areas of science. Often, they got similar answers. Only half of results in economics replicated. In pre-clinical cancer studies, it was worse; only 11% replicated.

  • Qt Design Studio 1.1 released

    We are happy to announce the release of Qt Design Studio 1.1 !

    Qt Design Studio is a UI design and development tool that enables designers and developers to rapidly prototype and develop complex UIs. Both designers and developers use Qt Design Studio and this makes collaboration between the two a lot simpler and more streamlined. To get an impression, you should watch this video.

    Since the Qt Design Studio 1.0 release last year we worked hard on bug fixes and new features.

  • Sublime Text and Language Server Protocol

    LSP - protocol for interactions between IDE and language server. The latter provides such means like autocompletion, goto implementation and etc. When IDE needs to show autocomplete choices on, for example, python language - it sends a request to the special server. And it responds with the necessary data. The cool part here is that it is an initiative of a big company - Microsoft.

XFS Copy-On-Write Support Being Improved, Always CoW Option

tuxmachines.org - Tor, 02/19/2019 - 14:22

One of the recent XFS innovations under work and maturing with time has been Copy on Write (CoW) support for this mature Linux file-systems. The XFS CoW support continues to be improved upon and an "always CoW" option is being prepared to always force this behavior.

Christoph Hellwig has been among the XFS developers working on the copy-on-write improvements as well as adding an always_cow sysfs option. The latest XFS CoW patches were sent out on Monday for review.

  • Install ImageMagick (Image Manipulation) Tool on RHEL/CentOS and Fedora

    ImageMagick is a free open source simple software suite for any kind of image manipulation that is used for creating, editing, converting, displaying image files.

    It can able to read and write over 200 image files such as JPEG, GIF, PNG, TIFF, and Photo CD image formats and it is also used for thumbnail or captcha generation. It also includes command line options for creating transparent or animated gif image formats and many more feature like resize, sharpen, rotate or add special effects to an image.

    To use ImageMagick tool with PHP or Perl programming language, you will need to install ImageMagick with Imagick PHP extension for PHP and ImageMagick-Perl extension for Perl.

  • Changes in Flathub land

    Flathub uses buildbot to to manage the builds, and we have updated and customized the UI a bit to be nicer for maintainers. For example, we now have a page listing all the apps ever built, with links to per-app pages showing builds of that app.

    We also integrated GitHub authentication so that maintainers of individual applications automatically have authority to do operations on their own apps and builds. For example, the home and per-app pages have buttons that let you start builds, which anyone with write permissions to the corresponding GitHub repository can use. Also, similarly they can cancel or retry the builds of their own apps. Previously you had to ask a Flathub administrator to restart or cancel a build, but no more!

5 Good Open Source Speech Recognition/Speech-to-Text Systems

tuxmachines.org - Tor, 02/19/2019 - 13:49

A speech-to-text (STT) system is as its name implies; A way of transforming the spoken words via sound into textual files that can be used later for any purpose.

Speech-to-text technology is extremely useful. It can be used for a lot of applications such as a automation of transcription, writing books/texts using your own sound only, enabling complicated analyses on information using the generated textual files and a lot of other things.

In the past, the speech-to-text technology was dominated by proprietary software and libraries; Open source alternatives didn’t exist or existed with extreme limitations and no community around. This is changing, today there are a lot of open source speech-to-text tools and libraries that you can use right now.

Here we list 5 of them.

Software: CLI File Viewers, 5 Excellent Free Mind Mapping Software and Sophos Snakeoil for Linux

tuxmachines.org - Tor, 02/19/2019 - 13:40
  • 3 tools for viewing files at the command line

    I always say you don't need to use the command line to use Linux effectively—I know many Linux users who never crack open a terminal window and are quite happy. However, even though I don't consider myself a techie, I spend about 20% of my computing time at the command line, manipulating files, processing text, and using utilities.

    One thing I often do in a terminal window is viewing files, whether text or word processor files. Sometimes it's just easier to use a command line utility than to fire up a text editor or a word processor.

    Here are three of the utilities I use to view files at the command line.

  • 5 Excellent Free Mind Mapping Software

    Structured thinking is a process of setting a framework to an unstructured problem. Having a structure not only helps to understand a particular problem, it also helps to identify areas which need more understanding. Structured thinking allows us to map ideas in structured fashion, thereby enabling the identification of areas which require the most thought.

    Mind mapping is a fairly free flowing concept. This means you need software that is versatile, and can adapt to your requirements. Your idea of a neat and tidy mind map might be another person’s idea of bamboozling. A map can concentrate very complex content in a small space such as a piece of paper. It helps to use both sides of your brain: the logical side and also the creative side. It’s a technique to help organize the way you think and stimulate your creativity: It can help you by developing, sorting and helping to memorize your ideas.

    Mind mapping software therefore offers an excellent way of capturing your thoughts in a structured way, brainstorming new ideas. Move away from simple lists, and use this software to link ideas in different ways. By thinking creatively, not linearly, we can seize on our big ideas.

    Microsoft's collaborative Slack-alike, Teams, is having a difficult start to the week, with users unable to log in to share their hopes, dreams and Word documents with their co-workers.

    Problems started at around 13:00 UTC, as users found themselves presented with connection errors as they attempted to hook up to the service. Naturally, they took to Twitter to share their experience.

  • Microsoft is going all-in on 'Inner Source' [Ed: Microsoft's de facto PR person at CBS on how Microsoft will keep giving malicious software with NSA back doors while calling it "open". Dr. Glyn Moody, to his credit, warned about it over a decade ago in Linux Journal when he said Microsoft would bamboozle nontechnical people/officials by claiming it itself is its competition and is "open source" (even when it's proprietary, with back doors).]
  • After Open Source, Microsoft Wants “Inner Source” For A Better Future [Ed: Having bribed OSI and others, Microsoft is now trying to redefine and totally control FOSS (all products proprietary but with openwashing for marketing purposes). Remember "Shared Source"? Microsoft keeps rebranding. Microsoft: we’re sort of kind of like “open”. We bought some things. BP: we’re sort of green. We changed our logo and mentioned words like “climate”.]
