This week in KDE: late holiday presents

Filed under
KDE

Most KDE contributors are still recovering from their holiday vacations, but nevertheless the first of my 2020 predictions has been fulfilled: KIO now makes remote locations available to non-KDE apps using FUSE mounts! This brings us to full feature parity with GNOME’s GVFS system and makes it painless to interact with files in remote locations using apps like LibreOffice, Blender, and VLC. Full support will be shipped to users with the Dolphin 20.04 release.

KaOS 2020.01

Filed under
KDE

A nice way of starting 2020 is to present to you the January release of a new stable ISO.

For the many changes in this release, two stand out. First one is the addition of signed kernel modules for Linux 5.4. All internal modules are now automatically signed during the kernel build, out of tree modules like virtualbox-modules and NVIDIA packages have the signing added too. Building of those modules was adjusted to use the kernel specific signing files during each and every rebuild. You can harden your system by adding module.sig_enforce=1 to your kernel boot line.

Educational Data Sets

Filed under
KDE
Sci/Tech

There are many online sources available that provide data sets for educational and study purposes. They cover many different areas (physics, statistics, medicine, etc.) and many tools and frameworks provide wrappers for them and allow you to easily play around with the data sets. In many cases, the technical tasks of fetching the data from the server, parsing it and installing it are completely transparent for users.

We recently added a similar functionality to LabPlot and we plan to release this new feature as part of the upcoming 2.8 version. The initial implementation for this was done by Ferencz Kovács during Google Summer of Code 2019.

KDE Plasma Plans New Look and New App Menu for 2020

Filed under
KDE

Nate Graham’s peek at the KDE roadmap for 2020 reveals these and other changes planned for Plasma, though not all are said to be guaranteed inclusion.

Breeze is KDE’s steely-cool theme, and is used by default in most (it not all) KDE-based Linux distributions, including KDE Neon, Kubuntu, and Manjaro KDE — but it might soon look a little different, as this mockup shows...

KStars v3.3.9 is Released

KDE
Software
Sci/Tech

We kickoff 2020 with a brand new KStars v3.3.9 release for Windows, MacOS, and Linux.

This release incorporates the continued improvements to KStars base while introducing new long-awaited features in a few areas.

Stretch Controls

Hy Murveit implemented adjustable and fast stretch controls for mono and color images within the FITS Viewer. These allow fine changes in Shadows, Midtones, and Highlights clipping even for high resolution astro-photos.

Adjusting the controls do not change the underlying data, only the previewed image. After any stretch adjustment is made, the user can always revert to the automatic stretching again by clicking on the small wizard icon at the bottom right corner of the controls panel.

Kate - LSP Client Status

Filed under
KDE

Unfortunately, for the 19.12.0 release, we still had the issue that the mapping of syntax highlighting modes to LSP language names was more or less hard-coded inside the C++ sources. This made it awkward to add other languages for which there is no 1:1 match of these two things (beside casing).

This is now rectified in master and backported to the 19.12 branch (should be in the next patch releases).

The mapping is now specified as a regular expression inside the JSON config that then is applied case-insensitive to the highlighting mode.

The shipped default config was adjusted to this, the current state in master & 19.12 is something like this...

Intel’s 5G-oriented Atom P5900 features up to 24 10nm Tremont cores

Like the C3000, the P5900 supports up to 128GB DDR4, now at up to 2933 MT/s. It similarly supports 16x PCIe 3.0, 16x SATA 3.0, 4x USB 3.0, and 4x USB 2.0 interfaces. However, the SATA links can now be reconfigured as up to 16x PCIe 2.0 or 16x USB 3.0, so you can now have up to 32x PCIe lanes. Other features include GPIO, 3x UARTs, and -40 to 85°C support. We saw no mention of OS support, but we imagine that like the Atom C3000, the Atom P5900 is primarily designed to run Linux. The C3000 has appeared on a variety of Linux-powered networking appliances such as Advantech’s FWA-1012VC, as well as numerous COM Express Type 7 modules like Avnet/MSC’s MSC C7B-DV. Earlier this month, it showed up on a Versalogic Grizzly SBC. Read more

Games: Ultimate Chicken Horse, Dota Underlords, Overclocking With GreenWithEnvy

  • Hilarious party-platformer 'Ultimate Chicken Horse' free update due next month

    Ultimate Chicken Horse, a party-platform where you build the platforms as you go is getting a sweet free update with some new toys to play with next month. A game you absolutely need to play too! After only just getting into it myself thanks to the Humble Sweet Farm Bundle last month, it was pretty hilarious to try. Clever Endeavour Games have now announced the "A·cobra·tic Update" which is due out on March 12, for all platforms and it's free. It's going to include a new Snake character (who rides a Skateboard), two new levels and four new blocks. Along with "a handful of improvements, minor additions to the game, and plenty of bug fixes". The new blocks flamethrower, one-way gate, cannon and beehive sound like they will be fun to screw with others.

  • Dota Underlords from Valve is out with the City Crawl campaign mode

    Valve's latest game, Dota Underlords, has today left Early Access and with it comes a huge patch full of new content and features. The biggest addition to the Underlords strategy game is the City Crawl campaign. A single-player mode, that explains a bit about what's going on. It seems "Mama Eeb" passed away, leaving a power vacuum in White Spire, with the four Underlords attempting to take control. City Crawl is where you do that, as you go through various different types of challenges and while doing so earn new outfits for the Underlords.

  • Linux Gaming: Overclock your Nvidia GPU on Linux with GreenWithEnvy

    Overclocking your Nvidia card on Linux used to be a nightmare. There was lots of different commands you had to type into the terminal, and there was no easy way to monitor your temperature and fan speeds. Thanks to Roberto Leinardi’s program GreenWithEnvy, you can now overclock with a simple, clean GUI.

Programming: AWK and Python

    An endearing feature of AWK is the flexibility of its syntax. Some other languages have very strict rules about how to write commands, and if you disobey the rules, you get error messages.

  • Easily Clip/Split Large Videos With this Python Script

    Sometimes you have may have a large video file, and you want to split that video into many smaller videos with start and end times that you specify yourself. And of course, you don’t want to do it manually with a video editor because it’s gonna take forever. What we are talking about for example, is when you have a video of 10 minutes, and you want to create 3 smaller clips out of it such that the first one is between 1:20 and 2:20 for example, and the second one is between 3:00 and 4:00 and the last one is between 7:10 and 8:15. Such things is theoretically hard, but not with Python and its amazing tools!

Linux (Kernel): Clear Linux, AMD Radeon Graphics and Raspberry Pi 4

  • One Of Clear Linux's Kernel Patches To Help With Boot Time Proposed For Upstreaming

    Besides Clear Linux delivering often leading x86_64 Linux performance at run-time, when it comes to boot performance it has also been at the forefront -- in some configurations, can boot in 300 ms. Intel has invested significantly in ensuring Clear Linux boots as fast as possible for when running in the cloud or on containers in order to respond to increased demand as quickly as possible as well as for use-cases like Clear Linux within automobiles where they need to get automobile cameras active within two seconds of power on. One of their many kernel patches could be on its way to the mainline kernel.

    While the Linux 5.5 kernel landed Broadcom BCM2711 SoC and Raspberry Pi 4 enablement, one of the loose ends has been getting the open-source "VC4" DRM driver wired up for the display hardware on this latest Raspberry Pi. Patches are now pending for VC4 DRM to provide that display support and could potentially see it mainlined for Linux 5.7.
