Pretty much regardless of your role, if your regular work involves doing stuff on the command line in Linux, you may find yourself in a situation where-in you'd want to compare two files using a command line utility. There are several command line tools that let you do this, and one among them is the 'cmp' command.

Reddit: Looking for the title of a Unix book I once had

Saturday 20th of May 2017 05:12:13 AM

The idea of the book was to learn how Unix worked by introducing system calls and using them to write your own versions of common Unix tools.

For the life of me, I can't remember what the book was called.

Reddit: Is Elementary OS stable with drivers?

Saturday 20th of May 2017 04:11:16 AM

So I was wondering if this specific distro is stable with GPU drivers for example etc

I plan to use the PC just for playing my steam games (the ones that are supported, I don't mind letting games go), work apps, etc surf net

I'm pretty casual about it, I don't really wanna pay 80 dollars for a legit copy of windows and I appreciate the fact my privacy is respected with this opensource software.

LXer: 3 benefits you didn’t expect from Linux containers

Saturday 20th of May 2017 03:24:52 AM
Containers started with technical people, so many of the benefits are known instinctively by users. But if you are new to containers, these benefits might not be so obvious.

Reddit: I can't get used to a tilling window manager

Saturday 20th of May 2017 12:57:00 AM

I have been playing around with i3 for about a week or so and I have ended up with a nice customization.

However, while I love the speed, the easy customization, and all the other stuff, the maximization part I don't get at all!

I have two 27" monitors each running 1920x1080. When I open up my browser in a workspace it automatically gets maximized. I hate having a maximized browser because so many websites just looks horrible and it makes it more difficult to read. My eyes has to go all the way across the monitor when I read.

Normally I open my browser not maximized, but perhaps 70% or so as that makes everything easier to read. The last 30% is kindda wasted, because I don't put anything there. Or perhaps I have conky running with some information I rarely need to look at. That way the browser window isn't too big.

When I work on web development I have my editor in one monitor and my browser in the other, but none of them are maximized. They are both located as close to the middle as possible as I sit in the middle of the dual monitor setup. I don't have to look all the way to the end of each monitor.

If I had smaller monitors, or only one monitor, then maximizing everything makes sense, I need the whole screen, but as soon as the monitor gets big and you run a dual monitor setup, maximization gets in the way IMHO.

Maximizing the editor also makes no sense when working with simple text like Markdown IMHO. The text is filling out the entire screen. It's just to much screen to read on.

I could make the browser and editor float, but then what's the point of the tiling window manager. If it's just about shortcuts, etc., then I can get most of that with Xfce4 (just as an example).

Am I the only one feeling this way?

TuxMachines: Events: QtCon, Akademy, Free and Open Source Software Compliance, Linux Plumbers Conference

Saturday 20th of May 2017 12:19:14 AM
  • Announcing QtCon Brasil 2017

    It's been almost a year since I, Filipe and Aracele were having a beer at Alexander Platz after the very last day of QtCon Berlin, when Aracele astutely came up with a very crazy idea of organizing QtCon in Brazil. Since then, we have been maturing such an idea and after a lot of work we are very glad to announce: QtCon Brasil 2017 happens from 18th to 20th August in São Paulo.

  • Join us at Akademy 2017 in Almería!

    This talk will illustrate the application areas for Input Methods by example, presenting short introductions to several international writing systems as well as emoji input. It will explain why solid Input Methods support is vital to KDE's goal of inclusivity and how Input Methods can make the act of writing easier for all of us.

  • Training in Foss Compliance

    The first training “Free and Open Source Software Compliance” is on June 23rd at KDAB’s Berlin training center. It will be held in German. Trainings in English at this and our other locations will follow later in the year. If you would like to learn how to navigate Open Source licensing with confidence, read more and sign up here.

  • Linux Kernel Memory Model Workshop Accepted into Linux Plumbers Conference

    A good understanding of the Linux kernel memory model is essential for a great many kernel-hacking and code-review tasks. Unfortunately, the current documentation (memory-barriers.txt) has been said to frighten small children, so this workshop’s goal is to demystify this memory model, including hands-on demos of the tools, help installing/running the tools, and help constructing appropriate litmus tests. These tools should go a long way toward the ultimate goal of automating the process of using memory models to frighten small children.

  • IBM’s OpenWhisk Stirs up Serverless IoT with Watson

    With the Internet of Things, the realms of embedded Linux and enterprise computing are increasingly intertwined, and serverless computing is the latest enterprise development paradigm that device developers should tune into. This event-driven variation on Platforms-as-a-Service (PaaS) can ease application development using ephemeral Docker containers, auto-scaling, and pay-per execution in the cloud. Serverless is seeing growing traction in enterprise applications that need fast deployment and don’t require extremely high performance or low latency, including many cloud-connected IoT applications.

TuxMachines: PCLinuxOS Roll-Up Release: Another Linux installed on my new notebook

Friday 19th of May 2017 11:30:24 PM

I happened across a new ISO image for the PCLinuxOS KDE desktop distribution this week.

PCLOS is a classic rolling-release Linux distribution, so this is just a "roll-up" release, pulling all of the updates since the last release together to make new installations easier, faster and more reliable.

Every time a new rolling release update is made we talk about those first two points, how it makes installation faster and easier, but I think my recent experience with two ASUS laptops shows that the last point can be important as well.

TuxMachines: GNOME News

Friday 19th of May 2017 11:14:44 PM
  • Petr Kovar: Plans for the next GNOME docs hackfest

    What we want to do differently this year is extending invitation to all people interested in GNOME content, whether it is upstream or downstream. We would especially like to see some Ubuntu folks attending. With Ubuntu moving to upstream GNOME, we are already seeing an increased number of docs patches coming from Ubuntu contributors, which is great, and I think having a joint documentation event could strengthen and expand the connections even more!

  • Improve focus and productivity by listening to different sounds

    Lately I found out that having a background ambient sound such as rain, wind, fireplace, really constrains me from any distraction.

    In doing so, inspired by Noisli.com, I created a GNOME Shell extension with similar functionality.

  • GNOME and Debian usability testing

    Intrigeri emailed me to share that "During the Contribute your skills to Debian event that took place in Paris last week-end, we conducted a usability testing session" of GNOME 3.22 and Debian 9. They have posted their usability test results at Intrigeri's blog: "GNOME and Debian usability testing, May 2017." The results are very interesting and I encourage you to read them!
