Don't compromise security. Learn the SELinux-respecting way to install NoMachine on openSUSE Leap 16. This guide provides a reusable policy framework based on least privilege to fix persistent Systemd and execstack errors with custom policy.
How a debate over C# vs Java int and specs led to the Lₐₓ/Lₐₜ/R (LAX/LAT/R) taxonomy: a framework for type classification.
Worker is a double-pane file manager for the X Window System on UN*X developed by Ralf Hoffmann and released under the GNU General Public License V2 or later.
Using systemd to set battery charge threshold automatically during booting on compatible ASUS laptops running Linux Kernel version 5.4 and above. Also, perusing the Linux Kernel source code to understand the history of "battery charge threshold" feature on ASUS laptops and how it works.
Setting up FreeBSD 13.0 to debug Redis using JetBrains CLion and gdb.
C# solution for the reverse integer LeetCode problem
How to install Windows 11 as VirtualBox guest in openSUSE Tumbelweed host. Should work for other hosts too.
IceWM was an accidental discovery made during my quest for a minimal openSUSE system. I replaced KDE Plasma 5 with it. I am totally satisfied.
NoMachine is a very good remote desktop solution for Linux. It installs fine on openSUSE Leap while on openSUSE Tumbleweed the necessary systemd service, nxserver.service, does not get installed. After manually installing nxserver.service, all is good.
KDE Plasma's official File Manager, Dolphin, has a bug which forced me off of openSUSE Leap 15.2. I installed openSUSE Tumbleweed in the hope that the newer versions of KDE Plasma might have gotten rid of the bug. I was shocked when I saw the dangerous bug eerily smile at me in openSUSE Tumbleweed.
The steps I followed to properly set up KDE Plasma 5 on FreeBSD in VirtuaBox guest on an openSUSE Leap 15.1 host.
Fedora 32 as a VirtualBox guest is stuck at 800x600 resolution. Installation of VirtualBox Guest Additions version 6.0.18 impossible due to compilation errors. Got hold of VirtualBox Guest Additions version 6.1.8 and it got installed. However, it works only partly.
I tried to connect two pretty old laptops running openSUSE Leap 15.1 with KDE Plasma 5 to create a Local Area Network (LAN). This is a summary of my struggles.
A VirtualBox Guest Additions bug defined in the Ticket #19496 caused my freshly installed openSUSE Tumbleweed to have resolution stuck at 800x600. This blog post is about my experiments and observations.
I installed FreeBSD 11.1 a couple of days ago on my decade-old Dell XPS M1330 with Intel Core 2 Duo T8100 processor and 4 GB RAM. I had a terrible time as I ended up repeating the installation routine three times. Or was it four? The installation was trouble-free,
