Linux/Chrome on Chromebook using Crouton

There are many articles about this on the web. This is just a reminder to me as to what I’ve been doing.

Change boot to developer mode

Doing the following deletes all local data on your system. You can always reinstall the Operating System (Chrome seems to do that remotely). But your data is wiped after you do this.

  • Hold down the ESC + ↻ (refresh) key (the refresh key is where F3 would be on a normal keyboard)
  • While holding them down push the ⏽ (power) key (top right corner).

Installing Vidyo on Ubuntu 16.10

I need to use Vidyo conferencing software for some projects I’m on. Because I just reinstalled Ubuntu 16.04, I needed to reinstall the Vidyo desktop.

This is not easy, since the installation file Vidyo directs you to contains a dependency that is not available on Ubuntu 16.10 (libqt4-gui).

There are various solutions out there, though I was not able to get the one proposed by Vidyo itself to work.

The one that did work for me is on the CERN site. Read the rest of this entry »


Displaylink and Ubuntu 16.10 and 17.04

I have a new supercool three screen setup in my office.

To run this, I am using two cables: A old-style displayport cable to the middle screen, and HDMI cables, via a Dell USB3 Docking station, to the side screens.

Running screens via a USB docking station requires me to use DisplayLink. Fortunately, Displaylink have an Ubuntu driver. Unfortunately, this doesn’t seem to work with 17.04 and getting it to work well with 16.10 LTS requires a little fiddling. Read the rest of this entry »


How to backup an Ubuntu system using Dropbox

Dual booting Windows 10 and Ubuntu 15.04

Some quick notes, from memory, about how I successfully setup Windows 10 and Ubuntu 15.04 to dual boot. The starting point was a new Windows 8.1 computer which I then updated to Windows 10.

Warning about this post

Before you do anything at all, realise that following the instructions here could completely destroy your computer’s software: you might end up bricking it (i.e. changing it so that nothing starts); you might end up wiping out your data, the original operation system, or something else. I don’t mind that kind of thing happening to me and I’ve never not been able to fix things back. But I also have support you may not: e. Read the rest of this entry »

How to draw a circle in GIMP. Seriously.

I use GIMP, the free graphics software package, all the time. But boy it can be awkward at times. Here’s how to draw a circle or elipse (like the one in the photo below):

Ellipse select tool > Start selecting > Hold down shift > Click on the circle to select it > Edit (Menu) > Stroke Selection – Voila!
Alternative method: Select a circle again > Fill it > Select (menu) > Shrink few pixels > Delete

Weaponised viruses: Flame and Stuxnet

The Globe and Mail has an article today about  evidence that the makers of Flame, which it describes as “the most complex pieces of malware ever designed,” are issuing instructions for it to self destruct.
