So, I've been facing some DNS issues with my Ubuntu box and needed to do some debugging. While I was certain that my router was assigning the Google DNS servers (8.8.8.8 and 8.8.4.4) via DHCP to my machine, I needed to make sure that they were actually being used. Usually, I would be able to tell by looking at the output of /etc/resolv.conf oslt. However what I found in resolv.conf was

So I have a Xubuntu box, an old PC that was running Windows previously. All is peachy with the Linux install bar one thing: every time I shutdown the system, it shuts down fine, but immediately restarts again. This wasn't happening with Windows and appeared to be an issue particular to Linux or Ubuntu.

Freeplane, a fork of the mind-mapping program, Freemind, works really well. Except for the fact that in my (K)Ubuntu installation, it sometimes hangs in the middle of editing a node. Once it becomes non-responsive, the only fix is to kill the process and restart the program. The version of Freeplane in Ubuntu 18.04 is 1.6.13. However, the current version (March 2019) of Freeplane is 1.7.7. So, it's highly possible that upgrading Freeplane to the latest version will fix this issue.

Today, I started dabbling in doing some screen recording in Linux and while I could find programs to record the screen, I couldn't get the audio working as I wanted. By default, the programs record either the system audio, or the mic audio (or if the program is shit, neither); they don't record both the system audio and the mic audio. The fix for this on my Kubuntu 16.04 (Xenial) system which uses the Pulseaudio system to manage audio is as follows:

So I've been having trouble getting a Windows program to work in Wine (Windows emulator) on my Kubuntu 16.04 system. It's a simple program but one that requires .NET 3.5. Considering its simplicity, I thought that it'd work fine using just Mono and it did fire up. However, it wasn't terribly usable throwing constant errors and being very buggy. So I had to also install .NET 3.5.

On a fresh Debian 8 (Jessie) install, I found that I couldn't update the package repository using apt because security.debian.org was always timing out. While I initially thought this was because of a mirroring issue oslt, it turns out that it's because I was trying to access it via the IPV6 that my VPS was using. Turns out that the fix is reasonably straightforward. You simply tell apt not to bother with ipv6 and simply use ipv4 … like so:

echo 'Acquire::ForceIPv4 "true";' >> /etc/apt/apt.conf.d/99force-ipv4
