To quote Wikipedia, A roaming user profile is a concept in the Windows NT family of operating systems that allows users with a computer joined to a Windows Server domain to log on to any computer on the same network and access their documents and have a consistent desktop experience, such as applications remembering toolbar … Continue reading Roaming profile on Linux in 2017
A while ago I had purchased a Raspberry Pi 3 to learn more about building software on the ARM platform (IoT), and getting to know configuration management software like SaltStack. Since I intended to compile software on the Pi, I looked into external cooling solutions and found that adding a heat sink and fan should … Continue reading Adding an external fan to the Raspberry Pi 3 Model B
While waiting for Manjaro 17.0 to be released, have created RC ISOs for Manjaro OpenRC 17.0 Xfce edition. Highlights: Kernel updated to 4.9.x series (next LTS). Reverted to using ALSA by default (decided by voting, see here for reference). Old CLI installer patched to work with manjaro-tools 0.13.8 (changes available here). Download: https://sourceforge.net/projects/manjaro-openrc/files/17.0/ P.S. May … Continue reading Manjaro OpenRC 17.0 Xfce Development ISOs [RC]
After about a month of development (mostly over the weekends), Manjaro OpenRC 16.10.2 ISO has been released. It was originally not intended as a development edition, but become one since I noticed that it failed to boot in EFI mode both in Virtualbox as well as on bare metal, and was unable to fix it … Continue reading Manjaro OpenRC 16.10.2 ISO released!
It has been more than two years since I switched from using systemd on manjaro! Since that time I have been using OpenRC on manjaro, along with Slackware on my main system (systemd free out of the box). Has been a nice ride so far 🙂 P.S.

I find tiling helpful when I have to work with the contents of two windows at once, or when comparing things. By native window tiling I mean that we will be using only the native commands of a particular window manager and not any external program. Fluxbox The following can be added to ~/.fluxbox/keys # … Continue reading Native Window Snapping / Window Tiling with Fluxbox, Openbox, and xfwm4 (Xfce)
With the increasing complexity of systemd, I decided to look for alternatives. After some searching and experimentation, I settled upon OpenRC. OpenRC is a dependency based rc system that works with the system provided init program, normally sysvinit. Before proceeding furthur, let me list some of the resources available: 1) Manjaro Linux wiki 2) Manjaro … Continue reading Using OpenRC on Arch / Archbang / Manjaro Linux.
