I was recently gifted a Satechi WiFi Travel Router & Charger. Currently available on Amazon for £35. It's a clever little device with several useful functions: Travel adapter. Plugs into most power sockets and has a universal plug on top. Two USB charging sockets. Connect to Ethernet and share the signal via WiFi. Connect to WiFi and share the signal via WiFi or Ethernet. …

One of the most addicting aspects of Open Source software is the ability to scratch one's own itches. I've been blogging since 2004 - and while I'd never mistake longevity for expertise - I do take a certain pride in letting my readers know that I've spent over a decade bashing out words. So, I decided to build a simple widget which would display my posting history in a calendar style. And…

After much kerfuffle, the world has finally got used to the new Google logo. Well, almost. My eye is continually caught by the poor contrast of the yellow "O" against its background. Take a look... This is Google's default logo on its regular grey background. The contrast ratio between the yellow and grey is 1.50. That fails to meet current accessibility guidelines. This is just awful - I …

A couple of months ago I noticed there was an auction of Sci-Fi related material in London. The catalogue was amazing! The original Leela costume from Doctor Who, costumes from Star Trek, gizmos from Blade Runner - and a whole bunch of Star Wars props! Sadly, I couldn't afford the original pieces of the Death Star (expected price of £10k-20k) nor the Millennium Falcon blueprints (a more …

I've been busy writing the definitive Sercomm Camera API documentation. (No, you need a hobby!) While doing so, I noticed that I couldn't get my Pan/Tilt/Zoom camera to... well... pan! No lateral movement whatsoever. It'd move up and down - but its left and right movement was non-existant. I could hear the stepper motor whirring, but it wasn't producing any movement. Weird... TO THE…

If you thought Web Fonts were pretty nifty, then you're going to think font subsetting is really cool. No, honestly! It is! As I've written about before you can dramatically reduce the size of your Web Fonts by cutting out characters that you don't need. For example, suppose you don't need to include the русский алфавит - you can immediately drop 66 letters (upper- and lower-case), a whole load…

Eight years after I published this blog post, I helped officially release all these domain names as open data! Funny how life works out, eh? Would you like to know every domain name the UK Government had registered? Of course you would! There could be all sorts of interesting tit-bits hidden in there (ProtectAndSurvive.gov.uk? EbolaOutbreak2017.nhs.uk? MinistryOfTruth.police.uk?) Rather than…

The one book I insist my new hires read before starting is Edward de Bono's "Simplicity". It suggests that we should value others' time over our own. Every hour we spend making things simple gives a net benefit to humanity. Whether it is laws, industrial design, software, or documentation - our goal should be to make things radically simple. Not only does simplicity save time - it also saves…

Earlier this year, I attended a lecture given by Alan Rusbridger - the outgoing editor of The Guardian - entitled "The World After Snowden." Held at Oxford University, and attended by journalists, technologists, and former spies - it was an exceptionally interesting talk and provoked a lively debate over dinner. In light of the publication of the disastrous Investigatory Powers Bill, I've…

Regular readers will know that I have solar panels and an electric car. Is there any way to hook the panels up so they directly charge the car? Can I set my electrical system up to divert surplus electricity into the car when my house isn't using it. This is what I do with my hot water iBoost - when household energy usage is low, it automatically switches on my immersion heater. Can I rig up…

Another in my occasional series on the usability of toilets! It's hard wandering around seeing the mistakes which are made by designers. Perhaps it's poor keming on fonts, or a hotel room light switch which makes no sense, or - in my case - bogs. Lots of toilets incorporate a "dual flush." Press one button to unleash a deluge sufficient to sink all but the hardiest of bowel-movements, press a…

In the glorious past, Amazon had an API for interacting with its "Wishlist" service. Not any more though. So, here's the inspiring story of how a rag-tag band of adventurers brought it back from the dead! Several years ago, Justin Scarpetti created a tool to extract data from an Amazon wishlist - the imaginatively named Amazon Wish Lister. It used that most vulgar of programming practices -…
