Desktop Customization – Theming

My current terminal “Terminator” does not seem to adhere to the theming – or anything much for that matter, but gnome-terminal does.

Terminator’s use of tiling is probably redundant with i3 and tmux, so will switch to gnome-terminal (by changing i3-sensible-terminal to gnome-terminal in ~/.config/i3/config.

gnome-terminal inherits the font and themeing from gtk.  Apparently (u)rxvt is more customizable/has plugin ecosystem, but I don’t think I need a plugin-ecosystem.  Such things are probably best left to vim and shell.

Desktop Customization

Worked through this video tutorial, which had some great hints for making nice fonts appear in Linux.  Previously, I could only seem to get decent fonts in Ubuntu, and for other reasons (primarily Nutanix CVM is based on CentOS) I wanted to use CentOS as my desktop.

The two things which had most impact on font appearance were

  1. Adding font that claims to be same as used in OS-X
  2. Installing a tool named infinality, which improves randering.
  3. Using lxappearance to set the default font for all GTK based  applications.

Both are described in the Tutorial

  • Installing OS-X Fonts : https://www.youtube.com/watch?v=ARKIwOlazKI&t=130s
  • Infinality Section : https://www.youtube.com/watch?v=ARKIwOlazKI&t=580s

Another nice idea from the series is to match, or at least give some thought to the Browser (Firefox)  window manager (i3) and GTK “Themes”.  The tutorial uses a single colorscheme across all elements to achieve a nice coherent look and feel.  Doing so has given me the ability to customize/use a lightweight window manager, but still retain nice fonts in the applications, browser and Windowing environment.

Forensic recovery of formatted SSD on MacBook Pro OS X

On a MacBook Pro, with OSX, after installing a 3rd party SSD, there is no option to issue a “Secure Erase” and only “Format” is offered.  After formatting the drive (prior to selling the MacBook) – I was able to recover hundreds of photos and other documents using this freeware tool. Test Disk. Run the tool as “photorec” to access the Photo Recovery features.

To get around this I overwrote the partition with /dev/random.  Since the /dev/random device is bounded by CPU – you’ll want to stop the Mac from sleeping during the process by issuing

sudo systemsetup -setcomputersleep Never

Before formatting, there are lots of personal family photos that are recoverable by anyone who goes looking.  After formatting, the only images available are the default graphics put onto disk during OS-X install.
