Ubuntu 14.04

Ubuntu 14.04 has been released and as per usual the upgrade went without any problems on both my laptop and net-book (Xubuntu).   If you have not yet tried/switched to Ubuntu I can only suggest you give it a try which, incidentally, you can do by running it from a CD/DVD without actually installing it on your machine! As expected, OneUbuntu cloud is no longer supported but as I posted previously, Dropbox is very well integrated and is performing perfectly for my requirements.

Ubuntu One –> Dropbox

Now that Canonical has announced the withdrawal of the Ubuntu One cloud service later this year I decided to take another look at Dropbox which I have previously tried but abandoned in favour of Ubuntu One’s cross platform capabilities. Well, Dropbox has come along and now the cross platform functionality, at least Ubuntu/Windows, is available in a seamless way. On Ubuntu you can install using the software centre. I’ve re-installed Dropbox and installed the Ubuntu app  and all is running fine with almost immediate notifications of any changes being done to files  being flagged to any platform sharing the account. You can find Dropbox here

Luminance HDR

If you like experimenting with your photographic images then do take a look at this open source HDR software. It’s very easy to use and you can create some neat HDR effects very quickly. You can read more and find a link here.

Ubuntu 13.10

As usual, no problems to install the latest version of Ubuntu using the upgrade function of the software manager, worked seamlessly on the laptop and for Xubuntu on the EEEPC notebook.

Geogebra

I recently came across this open source cross-platform application which is a dynamic maths software package. Absolutely magic! If only I’d had this when preparing for exams all those years ago.  It combines graphic ingenuity with  formulas and modelling.  If you are preparing for exams or even just curious about maths, algebra, geometry or basic calculus then do take a look at this.

The home page is here and there are loads of tutorials and examples to help get you started.

Libreoffice 4.0.3.3 Hyperlinks

If you have recently upgraded your Libreoffice to 4.0.3.3 and are having problems with your Hyperlinks not working as before then check the “Security” – Options -” and look for the box “Ctrl-click required to follow hyperlinks”. This seems to come on as default irrespective of the state of the security setting in the previous version you had installed. Just un-tick the box and your hyperlinks will work with a simple mouse click.

Plugins for GIMP

There are many plugins available for GIMP, the registry here being a good place to start. Two filter tools in particular caught my eye and I’ve been having fun playing with them both. Firstly FX_Foundry and secondly G’MIC. Both have a vast number of effects that you can apply to be tweak or completely re-model your images. I attach a twirl below which to me looks like a Fresnel lens effect.
