I'm using varnish to cache a REST service that's slow enough to cause me grief in development.

Out of the box it assumes you are caching your own server and that the client is already using the right host header.

To specify that it should use a host header to match the backend I'm using a config like

When I installed my system I wasn't quite happy with the way the installer divided my hard disk - but at the time I was in a hurry...

I have since found that repeated loading of databases during development used up all available space in /var and debug files were filling /tmp

So I had to figure out how to resize them.

Every now and again I find I have ssh access to one server - which has access to somewhere I need to get to - but I want direct access (eg to forward an X session)

It was remarkably painless

One small problem with the mail system.

It's great that Amazon actually offer a version of thier MP3 downloader for Linux - just a shame that it doesn't work for many distributions.

Fortunately clamz is available 

It's a great little command line utility with a very forgetable name.

Test the hard drive with

This may take hours to run and will do so as a background process.

Once complete run the following to see results

I recently bought a Sony e-reader, the main Linux package to support this is calibre but I found that it wouldn't automatically sync my ebooks.

 The FAQ says 

 "The linux kernel can export two version of SYSFS, one of which is deprecated."

Apparently Debian Lenny exports the deprecated version and you have to recompile the kernel to undo this.

Debian has a very strict policy on free and legal software. This helps keep everyone honest, but sometimes a pragmatic approach is called for. MP3 is a file format that is patent encumbered - but also in universal use.

I could use the supplied Ogg Vorbis tools but then my music wouldn't work everywhere I want it to.

So I want to install Lame which is only available in source.

I've just installed Debian Lenny and generally am impressed with how well things are auto detected and configured - so much easier than a few years ago - and in many ways easier than a Windows install where you have to constantly find 3rd party drivers to get things working.

 However getting wifi running was a bit trickier (largely because of FCC regulations  affecting licenses and default settings).
