A while back I posted an instruction on how to change the font size in urxvt (terminal emulator) on the fly. In that post, I used a perl extension from https://github.com/simmel/urxvt-resize-font. Tonight, I tried to setup this extension on a brand new laptop running Fedora 28. For some reason, it doesn’t work at all. Luckily, I found another perl extension which works quite well. Here’s how I got it working on this Fedora 28, with Sway tiling windows manager (instead of i3 because I run Wayland with this Fedora 28)....

FreeBSD 11.2-RELEASE was released a few days ago. This means it’s time to upgrade the FreeBSD running on my nas. For the most part, this was all what I did: After it’s been upgraded, I also need to update the Zpool. Let’s upgrade the zpool as suggested: Next is to update the boot code. If for whatever reason you’re following this step to update zpool (zroot) on your FreeBSD, make sure you know what is your boot disk is....

With fresh installation of Fedora 28 I wasn’t able to play any downloaded Japanese animations with the default movie player – Dragon player. My other machine which also runs Fedora 28 could play the movie fine. Without any doubts I must have installed some additional codecs on that machine. But which codecs? Like last time, Google I must search. I’m going to write this post so I wouldn’t have to repeatedly search for the same solution....

Tonight I started to review the learning material for Red Hat System Administration III to prepare for RHCSE exam. I need a machine with GUI, and all my CentOS 7 VMs are headless. So let’s install the GUI on it, shall I? First install epel repo, if it’s not yet installed: Then install the 2 groups: Tip, if “I” can’t remember the names of the groups, I can run this command to list all available groups:...

FreeBSD 12.0 install media :20180208 misses a lot of timezone file. E.g. it doesn’t have /usr/share/zoneinfo/Australia/Sydney. Ensure: zoneinfo package is installed. Then run: And confirm: Fri Feb 16 00:19:48 AEDT 2018

Here’s one way to locate it: Click on the Windows Start Menu icon. Type “Run”, and click on Run (Desktop App). Then, when the Run dialog box presents, just enter shell:common startup and hit the Enter key Ref: http://www.thewindowsclub.com/startup-folder-in-windows-8

Just a quick note to remind myself how I fixed the problem installing VirtualBox 5.2.10 on a Mac laptop running 10.13.4. The installation seemed to go well until it reached the end and reported failing to install. I’ve had this issues for a few weeks already and Google for solution seems to have hit and missed until today. I finally found a solution posted here: https://github.com/docksal/docksal/issues/417. Basically, I need to go the System Preferences and tick the box to allow ‘System software from developer “Oracle America, Inc....

Ever since I have FreeBSD 12 installed on a spare laptop, I notice that this is the most frequently used portable machine at home. (Of course, I still use my main desktop, which runs Fedoda 27, for everything.) I think one of the main reasons is that I like the experiences when I started using Linux years ago – not everything works out of the box, and sometimes I’m forced to learn and understand better about an issue before it can be fixed....

I just updated Ansible to version 2.5.0 tonight, and I came across this issue when I tried to run a playbook for an Ubuntu 16.04 machine: PLAY [Ansible Playbook for configuring odroid.***.com] *************************************************************************************** TASK [Gathering Facts] ***************************************************************************************************************************** fatal: [odroid.***.com]: FAILED! => {"changed": false, "cmd": "None -s system-product-name", "msg": "[Errno 2] No such file or directory: 'None'", "rc": 2} According to the issue #37911, the remote system doesn’t have the dmidecode package installed....
