My first reaction to the news of Steve Jobs’ death was annoyance; here we go, a never ending stream of praise will hit the media “he changed the way we think about computers” and more nonsense like that. Then came the news of Dennis Ritchie’s death and nobody noticed. Hardly anybody I know even knows who he was, including people in the IT industry. Well, he is the guy who developed the C programming language, every time you touch something with software inside chances are astronomical there’s C code involved, and had great influence on UNIX, OSX is based on this work.

Everybody was still going on about how Steve gave them their pretty shiny laptop (in exchange for, on average, 2000 euros) and how happy it makes them everyday. Fact is: people like pretty shiny things and will more easily look passed their flaws. Our brains are wired to distrust ugly things and Steven Jobs turned that into gold. Now he’s being praised for his “contribution to the computing industry”.

He did make his contribution to the world, no doubt, but the scale is highly exaggerated in my opinion. Mister Ritchie on the other hand deserves much more credit. You, dear reader, are effected by his work right now, regardless of what brand of computer you’re using. That reminds me of a blog post by Linus Torvalds (google his name if you don’t know how he is), more than 90% of all your activity on the Internet touches his work and he was the nobody on the party and Warren Beatty is a star.

Rest in peace mister Dennis Ritchie.

I’ve added some convenience methods to access GPS because people really seem to want it. Is should be fully backward compatible with earlier versions;

EXIFR::JPEG.new('enkhuizen.jpg').gps.latitude  # => 52.7197888888889
EXIFR::JPEG.new('enkhuizen.jpg').gps.longitude # => 5.28397777777778

Enjoy!

Just released EXIF Reader 1.0.6 Ruby gem. This is a bugfix release for issue 20. The TIFF decoder now reads as many frames as possible instead of throwing an exception when hitting a bad frame.

Omdat de dekking van mijn provider nogal slecht is, ik daarom te vaak geen radio 1 kan ontvangen op mijn telefoon en de NOS Tour de France live pagina mobiel onvriendelijk is, heb ik tijdelijk een kleine webapplicatie gelanceerd welke het live verslag van de NOS pagina serveert. Dit verslag wordt elke 15 seconden automatisch geupdate.

Zo, ik kan weer rustig in de trein zitten tijdens de etappe finales.

Update: De tour is alweer afgelopen en deze webapplicatie draait dus niet meer.

When streaming audio or video or serving largish files over HTTP you’ll eventually want to provide seeking resp. continue download capabilities to your application. I’ve cooked up some ring middleware to respond to partial content requests and mangle your application responses accordingly. It works well with the commonly used ring.middleware.file wrapper but do read the fine print.

Et voilá: ring-partial-content

I’ve uploaded both android-mode and elein to the marmalade package archive for easier installation;

M-x package-install <RET> android-mode <RET>

and/or

M-x package-install <RET> elein <RET>

Enjoy!

Na drie jaar met alleen een lendedoekje gelopen te hebben om te boeten voor de paarse periode heeft deze site weer stijl! Voor iedereen met zo’n moderne grafische web browser: border-radius, box-shadow en opgedrongen varianten uit de Akzidenz Grotesk font-family.

Update: met behangetje van squidfingers

I’ve always liked HTTP authentication (like basic and digest) over login pages because they look so.. technically savvy. Finally somebody who bothered to read an RFC to implement it and make me feel warm and welcome like peers do.

Okay, I must admit, it takes a customer just a couple of moments to request a logout button, which is a real pain to implement, if possible at all. And I wouldn’t want to login on something I care about from a public computer either. But it is very nice for web services!

Anyway here’s my implementation as ring middleware: ring-basic-authentication

I’ve bundled my emacs leiningen convenience functions into a package and dropped it on github for other people to use. It’s a collection of interactive commands for common lein tasks used within a project; elein-clean, elein-deps etc.

Mosts of the commands basically run lein using the emacs compile function, with the exception of elein-swank and elein-reswank. These also handle (re)connecting slime.

Curious?

• download elein.el
• copy it somewhere in you emacs load-path
• (require 'elein)
• open up a file in a leiningenize project
• M-x elein-version

I hope somebody finds this useful.

Today I released version 1.0.2 of EXIF Reader to fix a Ruby 1.8.6 incompatibility. Thanks to Jasper Haggenburg, Patrick Crowley, Jeffrey Warren and Ian Leitch for finding, analyzing and fixing this problem.
