Notes to myself! Suppose you want to create a surround sound file using Audacity. The app is a little obtuse, so this may clear up some confusion. When exporting, Audacity defaults to mixing down to stereo. You must adjust these settings: Edit → Preferences → Import/Export → Use Custom Mix Lay out your audio. Keep each track as mono. You can have as many tracks as you like and then downm…

Earlier this year I was moaning about my Nexus 6. Motorola's crappy battery technology is well documented, my phone was running so hot that the glue holding the device together became unstuck! Eventually, the battery failed. It would report being fully charged, but only run for a few minutes before switching off. Recalibrating and resetting the battery statistics failed to improve the…

This is a quick review of the ZeleSouris Vertical Mouse and a guide to setting it up on Linux. Four years ago, I got the latest Evoluent Vertical Mouse. It's a great device, but it's starting to show its age a bit. So, time for a new model. I'm doing a lot of travelling, so a wireless mouse is a must. Sadly, the Evoluent Wireless Mouse is £75. As good as their mice are, I wanted something …

So, I've submitted my first patch to the Linux Kernel! It's trivial set of documentation improvements - mostly done so I could see if I've got everything set up correctly. This blog post is more of an aide memoire than a fool proof guide - I hope future me finds it useful! Install and Configure git I'll leave you to figure out how to install git on your system - one thing you will need to is…

(These notes are mostly for my own benefit). Android is moving away from USB Mass Storage. You will no longer be able to plug in a USB cable and have your Android show up as a USB disk. There are some good technical reasons for this, but it is a pain if you want to copy some files to your phone. The new system - MTP - isn't automagically detected in Ubuntu. This is something which is likely…

I'm in love with my keyboard! The Microsoft Natural Ergonomic Keyboard 4000 is a dream to type on. Large, well spaced keys, split keyboard, and a whole host of extra media buttons. There's only one tiny problem. Two of the buttons don't work in Linux - specifically, the keyboard scroll buttons. This is a long standing bug in Linux, but luckily it is fairly easy to fix. Using Florian Diesch's…

It's available in 32bit or 64bit. Double click on the .deb that has been downloaded and it should install. Nice…

New! Read my 2018 guide to setting up the Evoluent in Linux The Evoluent Vertical Mouse 4 costs close to £100. Let's get that out of the way. This is a pretty expensive mouse. Considering they give away basic USB mice with cornflakes, why would anyone spend the cost of a Kindle on a pointing device? Let me explain... "The two things you've got to spend your money on in life are your bed …

An edited version of this paid-for post appeared at Moo.com on the 7th of June QR codes are awesome! I mean, you may think your moo mini-cards are pretty funky - but they're nothing without a QR code. Why do you hand your card over to someone? You want the recipient to plug your contact details into their address book, right? So you give them a bit of card and then you expect them to tap…

Twitter has announced that it will soon open up a native photo sharing service. Rather than using an external service like Embed.ly to retrieve thumbnails, all the data is embedded within Twitter Entities. So, if you request a status using "include_entities=true", you will be able to grab the image and display the thumbnail using the following code. function twitter_get_media($status) { …

I am no longer confused! Here is a quick tutorial in how to post images to Twitpic and Twitter when using OAuth. I'm indebted to Steve Corona of Twitpic, for his help with this. You can see the full code on Dabr's Google Code page. First of all, you'll need to have enabled OAuth for your Twitter client. I use Abraham's excellent OAuth libraries for PHP. This tutorial assumes you already…
