Toe-dipping into Radio

As a perfectly contented computer geek, I have always been aware of the world of amateur radio but I had too much going on in the IT world to really pay it much notice. Of course the Internet is the place where worlds collide and at some point a couple of weeks ago I found myself reading about a project called RTL-SDR, which meant nothing to me so as always when that happens I did a little digging to understand more about it.

That was the subtle start of my fall into the rabbit hole of Amateur Radio and I’m not sure if I’ll be coming back…

Fixing the non-moving mouse cursor in Chrome OS Vanilla builds for Virtualbox

I am able boot Hexxeh’s Chrome OS Vanilla builds in Virtualbox but I found the mouse cursor is stuck to the middle of the window.

I was able to solve this problem by selecting “Disable mouse pointer integration” from the Machine menu in Virtualbox’s display window.

You can also toggle this option using “Host” + I, the host is the right-ctrl button by default.

This problem seems to stem from Virtualbox’s feature that maps the cursor position from the host window, with this disabled you now need to click into the Window to allow the guest to capture the mouse and resume control from where you last left the cursor, which is not as nice but hopefully this bug will be fixed someday. However, if you find a better solution to the problem please leave a comment to let us know!

Fixing your preferred browser on (L)Ubuntu systems

I use Lubuntu on my trusty netbook, it’s become a nicely polished OS over the last few versions however it still has a few rough edges. One of which is defining a preferred browser.

The default browser on Lubuntu is Chromium, the unbranded version of Google Chrome. While it’s nice I’m still a hardened Firefox user and so I keep Chromium installed but I don’t use it unless diagnosing a browser-specific issue.

I have Firefox selected in “Preferences > Preferred Applications” as my default browser, however hyper-links in emails were still insisting on opening up in Chromium, which takes time as it’s rarely pre-loaded when I’m using the computer.

To fix this I ran this command in a terminal:

sudo update-alternatives --config x-www-browser

This provides some options for a preferred browser, I had two for Chromium and a third for Firefox, I entered the number for Firefox and from then on, no more closing unwanted browsers!
