It is probably every developer’s dream to create a programming language. It is a complex and difficult task, so it will remain just an unfulfilled dream for many.
But there is a chance to create something simpler – a domain specific language (DSL). A language, that covers a specific (and limited) domain.
Ruby helps here a lot – to create a DSL is really simple and easy.

I installed Ubuntu in a VirtualBox machine on OS X (pretty easy and straightforward), but to access a Mac harddrive from Ubuntu was slightly more complicated.

One of the ways how to remotely control Firefox is to use the JSSh (JavaScript Shell) plug-in. To successfully install the plug-in, it is necessary to find a suitable version for your Firefox version (1.x, 2.x, 3.x) and platform (Linux, Mac, Win). That is sometimes not so trivial…

Additionally there is a limitation in the plug-in: its communication port number cannot be (easily) changed, so it is not possible to start more JSSh (and Firefox) instances.

First, the actual status is described, later a new version of the JSSh plug-in is provided with examples.

Vim is my favourite editor. I search for tips from time to time – and there are still nice surprises. After a few years of using it, it is high time to write down my own list of useful tips :)

A new version of Rhotoalbum, a simple but powerful photo album generator written in Ruby, has been released.

The version 0.6 contains a lot of new features such as album statistics (number of photos, number of albums), EXIF support (exposure time, focal length, f-number and camera model), automatic album thumbnail creation from the first album photo, relative links and several bug fixes.

If you would like to know more, please, check the Rhotoalbum page.
