I’ve been buying LED bulbs but am surprised at their brightness, or rather lack of. Manufacturers often write the equivalent in watts of incandescent bulbs on the packet but it turns out they tend to, er, lie. Quite a lot. With the current boom in LED bulbs, a trustworthy comparison table is what’s needed. After … Continue reading Incandescent Bulbs and Lumens
List of Javascript Charting Libraries
I’m looking to make some pretty JavaScript charts and was wondering which library to use.

How to Create a DVD-Compatible Video in PiTiVi
I wanted to edit one of my geeky songs in PiTiVi and burn it to DVD. After searching around and trying a few things it seemed to work, so for reference, here’s how I did it. Important: Save the PiTiVi project before you start, as I’ve found it to be prone to crashing. Once the video and audio are ready, … Continue reading How to Create a DVD-Compatible Video in PiTiVi

How to Format PDFs for the Kindle
Like many, I love my Kindle. What a wonderful piece of technology. OK, the browser’s a bit slow and not powered by Opera but even so, having a world-wide 3G connection is fantastic, as is the great reading experience. However, some PDFs don’t look so good on that small screen. Here are some (almost) ideal settings that … Continue reading How to Format PDFs for the Kindle

You know that lonely feeling, where all the hip web designers and developers gather at the coolest conference and you’re stuck at your desk?

How to Show Japanese Text in Evince
A quick tip that might help others (or me, the next time I forget)… I found that Evince, Ubuntu’s default PDF viewer, doesn’t display Japanese characters, at least on my non-Japanese system. After a quick search it seems the answer is nice and simple – install the poppler-data package. So, either use the Synaptic Package Manager or … Continue reading How to Show Japanese Text in Evince
Opera Update: “Requires installation of untrusted packages”
On two separate installations of Ubuntu 10.10 I got the following message when trying to update Opera using Ubuntu’s Update Manager:“Requires installation of untrusted packages” Unfortunately, the only option available was to click the Close button with no help to fix the problem. Fortunately, there’s a solution, also on My Opera, that worked for me: my.opera.com/vinhphuc121583/blog/fix-error-requires-installation-of-untrusted-packages … Continue reading Opera Update: “Requires installation of untrusted packages”

With apologies to Johnny Cash, the sorry tale of a mailing list that takes no prisoners.

Learning SVG
I thought I’d share the resources that have most helped me learn SVG. It’s an old technology but getting a lot of interest recently so I finally got round to doing some experimenting myself (so far an SVG game and a geolocation demo). I still have a long way to go but already I’ve found myself returning to … Continue reading Learning SVG
