Finding 32-bit WAV audio files on Linux

I was trying to find a way to search my archive of recordings on Linux and return the filenames of 32-bit WAV audio files. It’s a little tricky, but I did it. You’ll need to install the ffprobe command (part of the ffmpeg package). I came up with this command. It’s quite long and maybe not the mostContinue reading “Finding 32-bit WAV audio files on Linux”

CD/DVD duplication on Linux with TurboJet

I was looking for easy methods of burning several CD or DVD images across several drives simultaneously on Linux, since burning 20+ CDs on one burner is pretty tedious. It’s possible to use some bash magic to loop cdrecord in parallel but I wanted a GUI app as an alternative to using Nero or AlcoholContinue reading “CD/DVD duplication on Linux with TurboJet”

Camera database

This is going to be a long article about photography and databases. Mostly databases, and in particular how to model certain photographic entities in a relational database. If you’re not interested in databases, stop reading now! I have quite a collection of cameras and lenses and I wanted to track as much information as possibleContinue reading “Camera database”

Merging my blogs

Anyone who has come to this page either from photos.jonathangazeley.com or blog.jonathangazeley.com will notice I’ve now merged the two blogs in a single site called http://www.jonathangazeley.com. For now there are automatic redirects in place, and my RSS feed and all historic links will continue to work. But please do change your bookmarks, and if youContinue reading “Merging my blogs”

Temporary Linux swap in user space

Once in a while, you might run into a situation where you need some extra RAM (or swap) for a short time. (I ran into this situation today while stitching some really enormous images in Hugin). Adding a new swap partition isn’t practical if you only need the extra swap space for a short time.Continue reading “Temporary Linux swap in user space”

My first Wikipedia article

For someone who nominally “doesn’t like writing”, I rather enjoy writing articles on my blog. I never particularly enjoyed English at school, but now that I have a technical job that requires me only to make brief notes, I relish the opportunity to write about something I’m interested in once in a while. I’ve beenContinue reading “My first Wikipedia article”

St Paul’s Church

Some time ago, back in 2001, I set up the first website for St Paul’s Church, Stockingford. There have been a few iterations since then, but today I’m pleased to announce the latest edition. It has been fully redesigned to include more dynamic elements, provide more useful information, and require less maintenance. It’s based onContinue reading “St Paul’s Church”

A strange suggestion

I happened to be looking at the website of a company that offers virtual private servers earlier today. This particular company has a box on their front page with a few questions about what you need your server to do, and it recommends you a suitable server package. But I was slightly surprised at theContinue reading “A strange suggestion”

Jonathan’s Blog now on new “hardware”

This blog, and my other blogs, used to run on a rather old server: two 1GHz Pentium III processors, 1GB memory and 2 x 18GB SCSI hard drives. I host with Ridgeon Network, which is owned by my friend Chris. I help him out with some networking stuff from time to time so he loanedContinue reading “Jonathan’s Blog now on new “hardware””

Building an email server using ClearOS

I’ve had a server at home for years now, and I’ve also been a professional sysadmin for at least three years. I know my way around Linux pretty well and for some time I’ve run my own web server and also other services. But one thing I’ve steered clear of until now is running myContinue reading “Building an email server using ClearOS”
