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!

Octa-core Cortex-A53 hacker SBC sells for $60

FriendlyARM’s $60, open spec “NanoPC-T3” SBC runs Android or Linux on an octa-core Cortex-A53 SoC packed with wireless and media interfaces, plus 8GB eMMC. The over-caffeinated board builders at Guangzhou, China-based FriendlyARM have shipped their highest-end hacker board yet. The NanoPC-T3 is almost identical to the NanoPC-T2 board, but swaps out the quad-core, Cortex-A9 Samsung S5P4418 SoC for a layout-compatible S5P6818 with eight Cortex-A53 cores that can be clocked dynamically from 400MHz to 1.4GHz. Last month, FriendlyARM’ unveiled an $11, quad-core NanoPi M1 single board computer with similarly open source hardware and Android and Linux software. Read more

Security Leftovers

  • Cockpit 0.104
    Cockpit is the modern Linux admin interface. There’s a new release every week. Here are the highlights from this weeks 0.104 release.
  • FFmpeg 3.0.2 "Einstein" Multimedia Framework Released with Updated Components
    Today, April 28, 2016, the development team behind the popular FFmpeg open-source and cross-platform multimedia framework has released the second maintenance release in the stable FFmpeg 3.0 "Einstein" series. FFmpeg 3.0 was a massive release announced in mid-February, which brought in numerous existing changes, including support for decoding and encoding Common Encryption (CENC) MP4 files, support for decoding DXV streams, as well as support for decoding Screenpresso SPV1 streams.
  • Using bubblewrap in xdg-app
    At the core of xdg-app is a small helper binary that uses Linux features like namespaces to set up sandbox for the application. The main difference between this helper and a full-blown container system is that it runs entirely as the user. It does not require root privileges, and can never allow you to get access to things you would not otherwise have.
  • Build System Fallbacks
    If you are using Builder from git (such as via jhbuild) or from the gnome-builder-3-20 branch (what will become 3.20.4) you can use Builder with the fallback build system. This is essentially our “NULL” build system and has been around forever. But today, these branches learned something so stupidly obvious I’m ashamed I didn’t do it 6 months ago when implementing Build Configurations.
  • Node.js version 6 is now available
