  • Luxoft launches open source automotive software development platform

    The automotive division of Luxoft Holding has launched PELUX 1.0, a base development platform designed to provide the building blocks for automotive software development projects, which is now available on Open Source.

  • Agedu – A Useful Tool for Tracking Down Wasted Disk Space in Linux

    Assume you are running short on disk space and you wanted to free up, by searching something that’s a waste of space and removing it or moving it to an archive medium. How do you track down right stuff to delete, that saves maximum space?

    Linux provides a standard du command, which scans entire disk and shows you which directories hold the huge amount of data. That can assist you narrow your search to the things most useful deleting.

    However, that only shows you what’s huge. What you actually want to know is what’s too huge. By default, du command will not let you differentiate between data that’s huge because you are doing something that needs it to be huge, and data that’s huge because you unpacked it once and ignored about it.

  • Kgotobed – A Kernel Module That Forcibly Shutdown Your System

    I know that staying up late is bad for the health. But, who cares? I have been a night owl for years. I usually go to bed after 12 am, sometimes after 1 am. The next morning, I snooze my alarm at least three times, wake up tired and grumpy. Everyday, I promise myself I will go to bed earlier, but ended up going to bed very late as usual. And, this cycle continues! If you’re anything like me, here is a good news. A fellow late nighter has developed a Kernel module named “Kgotobed” that forces you to go to bed at a specific time. That said it will forcibly shutdown your system.

  • New projects on Hosted Weblate

    Hosted Weblate provides also free hosting for free software projects. The hosting requests queue has grown too long and waited for more than month, so it's time to process it and include new projects. I hope that gives you have good motivation to spend Christmas break by translating free software.

  • IOHK announced the Beta release of Daedalus on Linux for Cardano [ADA] users

    One of the most prominent blockchain development firm, Input Output Hong Kong [IOHK] has announced the beta release of Daedalus on Linux Operating System. The Beta version is currently available for the entire Cardano community.

    The team mentioned that the Beta software can be tested with a small amount of ADA by mentioning the existing wallet recovery phrase which was supported on Windows and Mac OS. The Beta version is available for the users who can run the scripts on a terminal. Unlike Windows and Mac OS, the Linux Beta version does not have the feature for fetching updates from the blockchain. However, all the users are advised to install the initial production release manually.

  • Website Testing Checklist

    Before launching any website, it is necessary to make sure that the website is error free, user friendly and secure. So after completing the development task of any website, the site owner must confirm that the website is ready to launch by doing some important website testing checklist. Most common website testing checklists are mentioned here.

  • Gotop – Yet Another TUI Graphical Activity Monitor, Written In Go
  • Introduction to Haroopad

    Haroopad aims to give you the same experiences in editing regardless of the platform you are working on. Developed by the Korean programmer Rhio Kim, Haroopad is available from the project website for Microsoft Windows, Mac OS X, and Linux as binary packages for 32 and 64 bit systems. For this article we have tested the package for Debian GNU/Linux 9 (64 bit) and downloaded the according deb package.

  • tint 0.1.0

    A new release of the tint package just arrived on CRAN. Its name expands from tint is not tufte as the package offers a fresher take on the Tufte-style for html and pdf presentations.

    This version adds support for the tufte-book latex style. The package now supported handouts in html or pdf format (as before) but also book-length material. I am using this myself in a current draft and this is fully working, though (as always) subject to changes.

  • HandBrake 1.1 Open-Source Video Transcoder Released

    For fans of the HandBrake open-source, cross-platform video transcoder software, a big post-1.0 update is now available.

    The HandBrake 1.1 release tagged on Saturday introduces an improved user-interface with a redesigned main window, a new summary tab, updated icons with HiDPI support, and other UI alterations. There is also new/improved presets for Vimeo/YouTube, 4K presets for different devices, new presets for post-production video editing workflows, and other 4K video improvements. There is also improved Intel QuickSync Video support, including the first support for it on Linux.

  • Cardano ADA price Surges Ahead of the Beta Release Daedalus on Linux Software

    Cardano ADA has recently announced the release of the much awaited Daedalus on Linux. The communication was made via the Cardano community forum. Although the information about the software is limited, it stated clearly that it was ready for public beta testing. The network, however, is still collecting feedback from the community to ensure that all the different Linux distributions will be well catered for. Besides, the software will include certain levels of customization to improve the user experience. Besides, the beta testing is tailored towards Linux users that are comfortable operating a script in a terminal.

  • Cardano (ADA) Price Goes Up After Daedalus on Linux Beta Testing Goes Live

    The team who is in charge of Cardano (ADA) recently announced that its planning to release the highly anticipated Daedalus software which will run on Linux. This information was made public directly on the official Cardano website. However, the developers didn’t want to unveil too much information about the upcoming software and decided to keep their statement short and to the point.

  • This week in Usability & Productivity, part 13

    Another week in Usability & Productivity, another wish that I could make more announcements about all the cool stuff we have in progress! The wheels of software sometimes turn more slowly than we might wish, but in the end, the better result will be worth it. KDE’s patch review process is there to ensure that code quality is high as possible before making it in!

    Nevertheless, we landed some great improvements this week, including a few long-standing requests. Come and see:

  • GNOME 3.28 uses clickfinger behaviour by default on touchpads

    To reduce the number of bugs filed against libinput consider this a PSA: as of GNOME 3.28, the default click method on touchpads is the 'clickfinger' method (see the libinput documentation, it even has pictures). In short, rather than having a separate left/right button area on the bottom edge of the touchpad, right or middle clicks are now triggered by clicking with 2 or 3 fingers on the touchpad. This is the method macOS has been using for a decade or so.

  • Verbosio is dead… but I have a new code name, Aluminium, with the same ambition

    All of the above means that Verbosio, as a Mozilla Firefox-based XML editor with specific XML languages as add-ons to the editor, is truly and finally dead, and there’s no point trying to believe otherwise. Similarly, the need for a XUL IDE is dead as well. (Daniel Glazman and I need to get together to cry over a beer sometime.)

  • Know your limits

    When building software systems, we usually deal with data from external sources. This can be user input, data coming from other systems, etc. My basic assumption on any external data is: don’t trust it!

  • GNU Mcron 1.1.1 released

    We are pleased to announce the release of GNU Mcron 1.1.1,
    representing 48 commits, by 1 person over 3 weeks.

  • Pidgin 2.13 Linux Desktop Instant Messaging Client Released

    Desktop-based instant messaging clients are becoming increasingly rare in the age of mobile apps and browser-based alternatives, but Pidgin formerly known as GAIM continues moving along albeit slowly. Recently the Pidgin 2.13.0 release happened without much attention.

    Pidgin 2.13 was released back in March with a number of bug fixes, better support for dark themes, improved transparency handling, API updates, and more but it was mostly just about fixing a number of bugs. Pidgin 2.13.0 had been the first update in one year since Pidgin 2.12.

  • kTLS in Cubemap

    Cubemap, my video reflector, is getting TLS support. This isn't really because I think Cubemap video is very privacy-sensitive (although I suppose it does protect it against any meddling ISP middleboxes that would want to transcode the video), but putting non-TLS video on TLS pages is getting increasingly frowned upon by browsers—it used to provoke mixed content warnings, but now, it's usually just blocked outright.

    This took longer than one would expect, since Cubemap prides itself on extremely high performance. (Even when it was written, five years ago, it could sustain multiple 10gig links on a single, old quadcore.) Cubemap is different from regular HTTP servers in that it doesn't really care about small requests; it doesn't do HLS or MPEG-DASH (although HLS support is also on its way!), just a single very long stream of video, so startup time doesn't matter at all. To that extent, it uses sendfile() (from a buffer file, usually on tmpfs or similar), which wasn't compatible with TLS… until now.

  • A look at GNU/Linux exclusive Flowblade video editor

    As a journalism student, I deal with both print but also multimedia forms of journalism, on a daily basis.

    Generally speaking, I have always used various Adobe software for my needs, such as Audition for my audio, and Premiere for my video while in school, but I know that there is plenty of awesome and free (albeit I will concede, rarely as fully-featured) software out there that could be used to substitute. One example, is Flowblade.

    Flowblade is a GNU/Linux exclusive, which is pretty cool really, given that nowadays many of the tools and applications people use on GNU/Linux are available for other systems as well. Thankfully, Flowblade is pretty sophisticated, so many may find it to be more of a suitable replacement for other software, than expected from an exclusive.

    Not to be dismissive and say that all GNU/Linux exclusive software is terrible or anything, but its a fairly common opinion of less than stellar software attempting to emulate its Windows counterpart.

  • Linux Package Managers

    We’ll compare different Linux Package Managers. Between all Linux distributions, one of the things they share is the need to be able to install new software packages onto the system. Depending on the distribution, various package managers are available, allowing the user to install, manage, and remove packages easily and quickly. Package managers are very good at streamlining installs, with common installation locations and configurations. In this article, we will discuss the different available package managers, what distributions they can be used on, and what makes each unique. We will cover Debian-Based Package Managers, RedHat Enterprise Linux (RHEL)-Based Package Managers, and other custom designed package managers.

  • 10 Reasons why Linux is better for programmers and developers

    Linux based operating systems are very popular among programmers, developers and server administrators. But still, there are many new programmers unaware of the power of Linux and it’s flexibility. I’m talking about those programmers who’ve just started the career and been a Windows user for a long time.

  • Top 5 Popular Free Source Code Editors for Programmers

    A source code editor is a program specifically designed for editing source code of computer programs. It can be a stand-alone application or part of any IDE or web browser. It is the most important tool for programmers because editing a source code is the main job for a programmer.

Software: Weblate, GraphicsMagick, Curl, projectM

  • Weblate 2.20

    Weblate 2.20 has been released today. There are several performance improvements, new features and bug fixes.

  • GraphicsMagick – A Powerful Image Processing CLI Tool for Linux

    GraphicsMagick is a free open source, modern and powerful software suite for processing images. It was initially derived from ImageMagick, however, over the years, it has grown to be a fully independent project, with a number of improvements and additional features. It runs on all Unix-like operating system such as Linux, MacOS, and also runs on Windows.

    It offers a useful and efficient assortment of tools as well as libraries that allow for reading, writing, and manipulating your images in more than 88 well known formats (such as GIF, JPEG, JPEG-2000, PNG, PDF, PNM, and TIFF).

  • curl another host

    Sometimes you want to issue a curl command against a server, but you don't really want curl to resolve the host name in the given URL and use that, you want to tell it to go elsewhere. To the "wrong" host, which in this case of course happens to be the right host. Because you know better.

  • An introduction to projectM

    Many people have seen music visualizations before, whether in a music player on their computer, at a live concert, or possibly on a home stereo system. Those visualizations may have been generated using the open-source music-visualization software library that is part of projectM. Software-based abstract visualizers first appeared along with early MP3 music players as a sort of nifty thing to watch along with listening to your MP3s. One of the most powerful and innovative of these was a plugin for Winamp known as MilkDrop, which was developed by a Nullsoft (and later NVIDIA) employee named Ryan Geiss. The plugin was extensible by using visualization equation scripts (also known as "presets").

    Sometime later, a project to implement a cross-platform, MilkDrop-compatible, open-source (LGPL v2.1) music visualizer began: projectM. The main focus of the project is a library (libprojectM) to perform visualizations on audio data in realtime—using the same user-contributed script files as MilkDrop—along with reference implementations for various applications and platforms. The project, which began in 2003 and was first released in 2004, is of interest to many for its creative and unique visuals, its use by media-player projects, and its interesting design and features. After years of development and contributions, the project stalled, but now there are efforts to rejuvenate and modernize the code.

Software: Cockpit, Timekpr, Gerbera, Little Backup Box

  • Cockpit 165

    Cockpit is the modern Linux admin interface. We release regularly. Here are the release notes from version 165.

  • Timekpr – Control The Computer Usage Of User Accounts

    Nowadays, the kids are spending more time using Computers than the text books. So, ultimately, as parent and a teacher, you must keep an eye on them how much time they are spending on Computers, and you should limit their computer usage when it’s not necessary. There are plenty of parental control applications available to get this job done. The one today we are going to discuss is Timekpr-revived. It is originally known as Timekpr. The developer has renamed it to timekpr-revived and added some features in the new version.

    Timekpr is a parental control application that can be used to control the Computer usage. We can set time limit for the Computer for the Kid’s user account, and prevent them to use Computer for a very long time. We can set time duration, and at what time the Kid can able to login to the Computer. In layman terms, you can easily limit their daily usage based on a timed access duration and configure periods of day when they can or cannot log in.

  • Gerbera – A UPnP Media Server That Let’s You Stream Media on Home Network

    Gerbera is a feature-rich and powerful UPnP (Universal Plug and Play) media server with a pleasant and intuitive web user interface, which allows users to stream digital media (videos, images, audio etc..) through a home network and consume it on different types of UPnP compatible devices from mobile phone to tablets and many more.

  • Big Update for Little Backup Box

    After a few evenings of coding and testing, I rolled out a new version of Little Backup Box. It is one of the most significant updates in the project’s life, and it introduces new functionality and a wide range of improvements.

KDE: Qt, Plasma, QML, Usability & Productivity

  • Qt 5.11.1 and Plasma 5.13.1 in ktown ‘testing’ repository
    A couple of days ago I recompiled ‘poppler’ and the packages in ‘ktown’ that depend on it, and uploaded them into the repository as promised in my previous post. I did that because Slackware-current updated its own poppler package and mine needs to be kept in sync to prevent breakage in other parts of your Slackware computer. I hear you wonder, what is the difference between the Slackware poppler package and this ‘ktown’ package? Simple: my ‘poppler’ package contains support for Qt5 (in addition to the QT4 support in the original package) and that is required by other packages in the ‘ktown’ repository.

Programming: Python Maths Tools and Java SE

  • Essential Free Python Maths Tools
    Python is a very popular general purpose programming language — with good reason. It’s object oriented, semantically structured, extremely versatile, and well supported. Scientists favour Python because it’s easy to use and learn, offers a good set of built-in features, and is highly extensible. Python’s readability makes it an excellent first programming language. The Python Standard Library (PSL) is the the standard library that’s distributed with Python. The library comes with, among other things, modules that carry out many mathematical operations. The math module is one of the core modules in PSL which performs mathematical operations. The module gives access to the underlying C library functions for floating point math.
  • Oracle's new Java SE subs: Code and support for $25/processor/month
    Oracle’s put a price on Java SE and support: $25 per processor per month, and $2.50 per user per month on the desktop, or less if you buy lots for a long time. Big Red’s called this a Java SE Subscription and pitched it as “a commonly used model, popular with Linux distributions”. The company also reckons the new deal is better than a perpetual licence, because they involve “an up-front cost plus additional annual support and maintenance fees.”

Linux 4.18 RC2 Released From China

  • Linux 4.18-rc2
    Another week, another -rc. I'm still traveling - now in China - but at least I'm doing this rc Sunday _evening_ local time rather than _morning_. And next rc I'll be back home and over rmy jetlag (knock wood) so everything should be back to the traditional schedule. Anyway, it's early in the rc series yet, but things look fairly normal. About a third of the patch is drivers (drm and s390 stand out, but here's networking and block updates too, and misc noise all over). We also had some of the core dma files move from drivers/base/dma-* (and lib/dma-*) to kernel/dma/*. We sometimes do code movement (and other "renaming" things) after the merge window simply because it tends to be less disruptive that way. Another 20% is under "tools" - mainly due to some selftest updates for rseq, but there's some turbostat and perf tooling work too. We also had some noticeable filesystem updates, particularly to cifs. I'm going to point those out, because some of them probably shouldn't have been in rc2. They were "fixes" not in the "regressions" sense, but in the "missing features" sense. So please, people, the "fixes" during the rc series really should be things that are _regressions_. If it used to work, and it no longer does, then fixing that is a good and proper fix. Or if something oopses or has a security implication, then the fix for that is a real fix. But if it's something that has never worked, even if it "fixes" some behavior, then it's new development, and that should come in during the merge window. Just because you think it's a "fix" doesn't mean that it really is one, at least in the "during the rc series" sense. Anyway, with that small rant out of the way, the rest is mostly arch updates (x86, powerpc, arm64, mips), and core networking. Go forth and test. Things look fairly sane, it's not really all that scary. Shortlog appended for people who want to scan through what changed. Linus
