Getting started with Vim: The basics

15 hours 50 min ago
I remember the very first time I encountered Vim. I was a university student, and the computers in the computer science department's lab were installed with Ubuntu Linux. While I had been exposed to different Linux variations (like RHEL) even before my college years (Red Hat sold its CDs at Best Buy!), this was the first time I needed to use the Linux operating system regularly, because my classes required me to do so. Once I started using Linux, like many others before and after me, I began to feel like a "real programmer."read more

How to choose special characters, revisited

Sunday 24th of March 2019 09:57:27 PM
There's no euro symbol on my keyboard, but I can enter that character in any document or in my terminal with Ctrl + Shift + u +20ac. I can do the same with "umlaut a" (00e4) and "cedilla c" (00e7) and the degree symbol (00b0) and... Wait! Who am I kidding? There's no way I can remember all those Unicode code points. For this reason I wrote a script for quick and easy retrieval of my most-often-used special characters from a GUI.

  • An Intro to Threading in Python
    Python threading allows you to have different parts of your program run concurrently and can simplify your design. If you’ve got some experience in Python and want to speed up your program using threads, then this tutorial is for you!
  • Mu 1.1.0-alpha.1 Released
    We have just released the first “alpha” of the upcoming 1.1 version of Mu. To try it, follow the links on Mu’s download page. Mu is a team effort, so many thanks to all the volunteers who have contributed in innumerable ways to make this happen. This is the first of several “alpha” releases for the next version of Mu. Over the coming weeks we intend to release newer versions based upon feedback from you, our users. Please don’t hesitate to get in touch if you have comments, suggestions or have found a problem (bug). The more feedback we get, the better. While we carefully read all feedback, we can’t always respond to nor address such feedback (remember, we’re all volunteers). If you’re interested in what we’re up to, all our development work happens in the open on GitHub and you can even chat directly with us (we’re friendly, so come say, “Hi”). What exactly do we mean by “alpha”..?

Fedora and Red Hat: SuperIO, Microsoft Mono, Fedora Modularity, NeuroFedora, OpenShift and 'Data Economy' (Spying)

  • Even more fun with SuperIO
    There were a few slight hickups, in that when you read the data back from the device just one byte is predictably wrong, but nothing that can’t be worked around in software. Working around the wrong byte means we can verify the attestation checksum correctly. Now, don’t try flashing your EC with random binaries. The binaries look unsigned, don’t appear to have any kind of checksum, and flashing the wrong binary to the wrong hardware has the failure mode of “no I/O devices appear at boot” so unless you have a hardware programmer handy it’s probably best to wait for an update from your OEM.
  • Mono 5 Might Come For Fedora 30 While Other Fedora 31 Features Discussed
    Earlier this month was the feature proposal for Fedora 31 to finally upgrade to Mono 5, which has been out for nearly two years for this open-source .NET environment. This feature request has been approved for Fedora 31 while it's also been decided to allow it into Fedora 30 if it can land within the next week. The transition from Mono 4 to Mono 5 was blocked due to the build process depending upon some binary references that complicated the process for distributions like Fedora and Debian. But they've now overcome those challenges and are ready to introduce Mono 5 to Fedora users.

In this post, I’ll examine some of the barriers organizations face in the Data Economy and how they’re overcoming them.

LOCKDOWN Aiming To Be In Linux 5.2 For Tightening Up Hardware/Kernel Access

Google developer Matthew Garrett recently took over work on the long-standing "LOCKDOWN" kernel patches with a goal of preventing the running kernel image from being modified and strengthen the boundary between UID 0 and the kernel. These patches, which have been around for years and shipped by some Linux distributions, didn't make it into the recent Linux 5.1 merge window but now a pull request has been issued in trying to ship it with Linux 5.2.
