Why you need the command line. How many reasons can I come up with before breakfast?

1. The Command Line makes Linux tutorials easy.
When a tutorial gives you instructions in line commands, you don't have to learn the commands. You don't have to understand the commands. You don't even have to type the commands! All you really have to do is copy the commands and paste them into the terminal window. That's easier than instuctions that have to give you a road map on how to find the button.

2.The Command Line is fun.
This one is pretty counterinuitive, but the command line allows you to take a creative approach to problem solving that is enjoyable.

3. Conversely, the Command Line allows you to cut a straight line through some of the most tedious, repetitive computing drudge work that you'll ever have to face.
I'm talking about organizing your files, sorting, moving, and processing large numbers of files. I used to spend hours on these tasks, and I hated it. These are what the command line excels at. You save time, but you cut down dramatically on the boredom.

4.Any command can be a script.
If you know how to use the command line, you know how to automate the command line with crude, simplistic shell scripts that most real programmers will look at with disdain, but which work anyway. And once again, you don't have to understand the commands.

A couple of years ago, I found this tutorial in my favorite Linux forum about how to process avi files into DVDs. From this, I was able to write a script that I have used to automatically process avi files into DVD images in batches of a dozen at a time. I just copy the files into the directories and start the script and let it run for a couple of days, and then burn 12 DVDs bangbangbang, all at once.

Now, here's the part that's kind of cool, even if it makes me look dumb: I don't understand the commands! I don't know how my own script works! I just copied the commands from the tutorial into a text file in a certain sequence, made it executable, and ran it. The commands in the script did whatever the hell it is they do, while I did other things. And now I have a bunch of DVDs to watch.

So easy... and so powerful!

Time for pancakes.

If I hadn't been in a hurry

I could have had a much longer list, with many more specifics.

Not necessarily a good thing. How does the last post get 300 reads, and this one less than 50? I'm willing to pander; just tell me how. My next post will be: "Why I hate Ubuntu (even though it's awesome)". That ought to get a hit or two!

Manjaro-Arm is Shutting Down

It is with deep regret that we are announcing that the Manjaro-Arm team is shutting down. I started this project a little over a year ago with no intent to become the sole maintainer. Read more

KDE and Qt

  • The Novelty of KDE Neon
    The good folks at KDE managed to engage a market of Linux desktop users underserved by other distribution models. Or, maybe it’s just me. KDE has a long history in the desktop ecosystem. It was the first Linux desktop I was exposed to back in 2006. Back then, it was on OpenSUSE and it was clean and functional. For some reason after that, installing KDE had never really appealed to me. I’ve tested it out briefly when poking around at what the OpenSUSE guys were doing and I’ve run Kubuntu for brief snippets. For years, I’ve been trying to find out what type of desktop user I am and which distro fits my needs.
  • Tracking KDE Frameworks and Qt
    The KDE-FreeBSD team bumped Qt to 5.7.1 and KDE Frameworks to 5.31.0 in official ports last week, so we’re fairly up-to-date in that department. On FreeBSD, we still fully support Qt4 next to Qt5, so some of the delay in getting this stuff in is due to some shuffling of install locations. In particular, we’ve added qt-chooser in this round of updates, so that qmake is qmake — and no longer qmake-qt4 or some other suffixed binary. We use qt-chooser to switch out one or the other. Checking that this doesn’t break anything else — or at least making sure that everything still compiles — is what took the most time this round of updates.
  • Simple Menu Launcher for KDE Plasma 5.9
    Following "United" theme, there is also "Simple Menu" launcher for KDE Plasma 5.9. It's minimal, a smaller form of full screen menu; it's also clean, showing all applications at once. Honestly, it's UI is similar to Pantheon Menu in elementary OS but including categories. If you like horizontal-oriented menu, Simple Menu is suitable for you. It's available to install from KDE Store. Thanks to Sho for creating Simple Menu.
  • A Simple KDE Twitter Plasmoid
    This KDE Twitter Plasmoids offers a simpler alternative to a desktop Linux twitter app like Choqok. See tweets, send tweets, and check mentions.
  • Telegram desktop client for flatpak #2
    Some time ago I posted a blog post about how I packed telegram desktop client for flatpak. I’ve been updating it since then in some reasonable intervals as I don’t have time to update it more often and mostly because the telegram client’s build system breaks my build quite oftenly. Recently I discovered that someone managed to patch telegram to use system Qt libraries instead of building own patched Qt and building linking it statically. After some time I managed to adjust those patches and make them work with my build which allows me to use Qt from KDE runtimes. Here are new instructions how to get this work:
  • Building the latest greatest for Android AArch64 (with Vulkan teaser)
    Let’s say you got a 64-bit ARM device running Android. For instance, the Tegra X1-based NVIDIA Shield TV. Now, let’s say you are also interested in the latest greatest content from the dev branch, for example to try out some upcoming Vulkan enablers from here and here, and want to see all this running on the big screen with Android TV. How do we get Qt, or at least the basic modules like QtGui, QtQuick, etc. up and running on there?
  • Qt Quick WebGL Streaming
    WebGL Streaming is optimized for Qt Quick and allows you to run remote Qt Quick applications in a browser.

SUSE Leftovers

  • OBS got the power!
    Old build workers, rack mounted Old build workers, rack mounted One year after introducing a new kind of Open Build Service worker machines, the “lambkins”, the openSUSE Build Service got a big hardware refresh. The new machines, sponsored by SUSE, are equipped with: 2,8GHz AMD Opteron Processors (6348) 256 GB RAM one 120 GB SSD Four of them are located in a chassis with a height of 2 units and run 12-16 workers on them (virtual machines, that are building packages). That new build power allowed us to remove some of old machines from the pool. The unified hardware makes the management of the machines a lot easier now, even if there are still the most powerful old machines left.
  • openSUSE Heroes December meeting – final results
    While we had some fun and good food and drinks, we also managed to discuss a lot during the three days in the Nuremberg headquarter. This was needed because this was the first time that the Heroes came together in their current form. In the end, we managed to do no coding and even (nearly) no administration – but instead we started to discuss our (internal and external) policies and work flows – and did some decisions regarding the next steps and the future of the openSUSE infrastructure.
  • New and improved Inqlude web site
    During last year's Summer of Code I had the honor of mentoring Nanduni Indeewaree Nimalsiri. She worked on Inqlude, the comprehensive archive of third party Qt libraries, improving the tooling to create a better structured web site with additional features such as categorization by topic. She did an excellent job with it and all of her code ended up on the master branch. But we hadn't yet made the switch to change the default layout of the web site to fully take advantage of all her work. As part of SUSE's 15th Hack Week, which is taking place this week, I took some time to change that, put up some finishing touches, and switch the Inqlude web site to the new layout. So here we are. I proudly present the new improved home page of Inqlude.

Benchmarks Of Ubuntu 17.04 Beta vs. Antergos, Clear Linux, openSUSE Tumbleweed

For those curious how Ubuntu 17.04 is shaping up, considering this week was the "beta" release for participating flavors, I decided to take a fresh Ubuntu 17.04 x86_64 daily ISO and see how its performance compares to Ubuntu 17.10, Clear Linux 13600, Antergos 17.2, and openSUSE Tumbleweed. Read more
