Why Is Apache Ignoring Some Of My Virtual Hosts? Last night I learned an interesting lesson about Apache virtual host directives. On my development machine, I use named virtual hosts for the various projects I work on, a bit like this:

I've built a few sites now using the Concrete5 CMS, and on the whole I really love working with it. It provides a whole heap of really nice user-facing functionality out of the box, and makes it really easy to add your own. However, today I had to build something which seems routine and trivial, and found no way to do it.

This is another of those "interesting" tech support cases (where "interesting" means painful and tedious). Our platform collects lots of data for our customers, and generates lots of nice juicy reports for them in an assortment of formats. Being a sensible developer, I'd done this using a typical MVC pattern, so there are models which get data out of the database, and then different views to format it into each report.

I've got a pretty long-running script. In our live environment this runs under command line PHP, but for convenience on my dev machine I just run it through Apache.

Trouble was, after about ten minutes, I got a slightly different error:

So, one of the main reasons I chose an Android phone instead of an iPhone (apart from not wanting to follow the herd) was so that I could develop my own apps and run them on my own phone. Yes - I know you can write apps for iOS as well, but I'm all PC, Linux and open source, and Mac development is going to need a bigger technology shift than I want to make right now (although I wouldn't rule it out in the future).

I've been using Linux as my main development environment for a couple of months new (full details over here). The transition has been pretty easy on the whole, but I've been struggling with one of the most basic tasks - copying and pasting. For historical reasons, Linux has two ways of copying and pasting:
