I’ve been experimenting a bit with the <canvas> tag. And hey, what’s a better way to use it right now than to make a browser screen full of snow? It even works in Internet Explorer (using excanvas) although pretty slow. For best results view in your favorite non-crappy standards compliant browser.

View a demo here. And if you want to tinker with it, download the sources from Google Code (open source under the MIT/X11 license).

Want to learn more about the <canvas> tag? Try this tutorial from diveintohtml5.org or the one from Mozilla.

Merry christmas!

Wondering why those cool ‘image rotate’ buttons you’ve seen in the WordPress 2.9 video aren’t working on your installation? They apparently depend on a PHP function which isn’t very widely available, and hence, they don’t show up.

I’ve created a ticket for this bug in WP’s bug filing system, so go there and vote for it so the developers can fix it in 2.9.1!

I wrote a little shell script that enables you to query The Twol (you know, my little pet project that provides instant information on lots of things) from the terminal (command line interface).

So, now you can do stuff like:

» Translate sentences from English to German (and many other languages)
twol translate en de I would really like a nice cold beer

» Get the weather for virtually any city in the world
twol weather St. Petersburg, Russia

» Check if a Twitter username is still free
twol twitterusernamefree stevejobs

Right from the command line (under Mac OS X and Linux at least :)

You need PHP to run the script. In Mac OS X that’s included out of the box, under Linux you might need to install php5-cli or another package with a similiar name.

Then you can simply:

• download the script
• copy it somewhere in your $PATH
  cp twol /usr/local/bin
• make it executable
  chmod u+x /user/local/bin/twol
• have fun!

Twitter is a typical example of a cloud service. Unfortunately, having all your tweets in the cloud instead of on your hard drive has a large drawback: things can go wrong. A few days ago T-mobile subscribers lost all of their data because of a large server outage at Danger, a Microsoft subsidiary. Something like that could happen at Twitter too, meaning that all of your beloved pieces of 140-character poetry are gone.

Furthermore, Twitter has an artificial limit in place that limits you to viewing your last 3,200 tweets. I’m an avid user of Twitter myself, and seeing my number of tweets rapidly reaching to the 3,200 limit i set out to do something about it and backup my tweets.

There are several solutions for doing this. But many of these didn’t fit my needs. Most of them require you to enter your username/password, which isn’t a very cool thing or are a bit clunky in their user interface.

So, i wrote something myself called BackupTweets. It’s completely open source (GPL-licensed), so you can download the whole package and run it from your own web server. The only thing you need is a web server running PHP.

You simply enter your username/password and press ‘GO’. The application will fetch all of your tweets in their original format (straight from the API) and save them as a big JSON file (for archiving and later processing), but also as a handy HTML file.

If you’re comfortable with entering your username/pass you can check out the demo. If you’re not you can download the whole package as a zip or check out the source code directly from Google Code.

Read this announcement in Dutch.

I’d like to introduce you to a little project i’ve been working on for the past time. It’s called The Twol and it’s a new way to get all kinds of instant information using a command-line like interface on the web or using Twitter.

How does it work? The Twol works by entering simple commands, either using the interface on the website or by sending tweets to @twol on Twitter. Take a look at the screenshot here below for an example:

Currently there are around 20 commands, that you can use to..

• Get the weather on a random city in the world
• Translate sentences from any language to any other language
• Check if a username on Twitter is still free
• Get an answer to any question from the magic eight ball
• Get inspiration from the Oblique Strategies

If you speak Dutch you might also enjoy some commands from my art site, 365 DAGEN HAY, including dooddoeners, onbegrijpelijke moppen, de Nimweegs vertaler and of course the Wilders citaten generator.

You might ask how this differs from some of the functions from Google. Well, Google always returns search results, which might not be the thing you’re looking for when searching for the current weather in Rome. Furthermore, there are many other commands that might not be the first result on Google. Of course Google search results don’t integrate in Twitter.

In that sense, The Twol is more like the classic command line or an IRC bot, with the difference that you don’t need to leave your browser or Twitter client to get quick information.

Note that when using Twitter, it can take up to 20 seconds to get a reply back. This is a result of the way Twitter works, unfortunately i can’t do anything about that. If it does longer than 20 seconds though, The Twol might be broken. Please let me know so i can fix things :) Of course, the website works instantly.

Of course, this is all still very much in beta so i’d like you to test the Twol and give feedback and what works, what doesn’t work, and what commands you’d like to see added (if you’re a little technical, you might be able to write your own commands in the future). Right now you can already hack a little bit using The Twol’s API.

You can give feedback using the comment form here below, by mailing me or of course by using The Twol itself.

Have fun!

My niece needed a piece of simple software to measure reaction times for a school research project. Apparently, it isn’t that simple to find a simple tool to accomplish that, so i made something in an afternoon that runs in a browser she could use.

The reaction test goes like this: after clicking ’start the test’ ten random items appear, either a small image or a sound. You then need to press the spacebar as fast as you can. After the test is over a scorecard appears with your reaction times in miliseconds.

The application should work in Firefox, Opera, Safari and Chrome. I haven’t tested it in some other browsers (*cough* Internet Explorer), so if it doesn’t work try Firefox.

Try a demo, get the code here as a zip or check out directly from Subversion.

Creative Commons published a report yesterday about how people interpret the term ‘non-commercial’ in some of their licenses. Interesting stuff, because the term ‘non-commercial’ is a pretty ambiguous one, that can lead to fierce debates within the free culture and open source movements.

I regularly get the question asked why Wikipedia doesn’t use a non-commercial license, and hence, doesn’t accept any non-commercial content onto its website, like all those wonderful NC-licensed photographs from Flickr. Also, the blog you’re reading right now is NC-licensed, and some of my photographs on Flickr as well.

It’s a difficult question, but it might have something to do with the nature of the work.

The main problem with NC-licenses is the ambiguity of the term ‘non-commercial’ when reusing content. The CC-research has shown that the interpretation of ‘NC’ is pretty much the same with both users and creators, even around the globe. However, that doesn’t really resolve the issue of ambiguity, as re-stating the definition in the license itself, or creating more licenses has been shown in this report to be a bad idea.

That isn’t as big a problem for individual creators though. Reuse of media will probably stay within the ‘personal use’ or ‘redistribute’ limits, and the NC license mostly touches upon all cases where people might make money from the content in a commercial way. Modifications to the original media are not very common.

This isn’t the case however with a project like Wikipedia, where mass collaboration is the basis of the medium and it is really inherent to creating content. Any ambiguity on how ‘non-commercial’ should be interpreted is likely to much more of a problem than with works created by an individual.

That’s why it’s so important, for projects like Wikipedia, to use a license such as BY-SA that it usable by anyone, at anytime, for any purpose without that ambiguity.

Fortunately, there is a solution now that enables the Emoji icons for free, without jailbreaking or using the developer tools. Here’s how:

1) First: go to the App store on your iPhone and search for ’spell number’, then tap on the applications icon.

2) Go ahead and install the app. It’s free!. You might have to type your password here.

3) After installing, open the app and type ‘9876543.21′ (without the quotes). That’s it. Now exit the app and go to ‘Settings’.

4) Drill down to General -> Keyboard -> International Keyboards -> Japanese

5) And there you have it! The famous ‘Emoji’ switch! The only thing you have to do now is set this to ‘on’.

6) Enter Notes or some other application where you can type and have fun!

• Try FlickrStreamr 0.3
• Download the source code (BSD / GPL licensed)
  

I’ve uploaded the newest version of FlickrStreamr. FlickrStreamr is a tool to view a continuously updating stream of all recently uploaded photographs from Flickr. On a normal day, around 3000-6000 photos are uploaded to Flickr every minute. This tool lets you view those photographs in a way that is a little bit more sophisticated than hitting ‘reload’ on the recent photographs page on Flickr.

I’ve done a lot of work on making this new version more easier to use, with a less cluttered interface. There’s just one button right now: play/pause. Hit it, and watch the photographs refresh, hover over a photograph to view a preview or click it to go to the photo page on Flickr.com

I’ve added some JavaScript that adjusts the number of thumbnails on your screen. The larger your screen resolution, the more thumbnails you will see. So, you don’t need to scroll the FlickrStreamr page to view more thumbnails. When all thumbnails are updated, the new thumbnails simply update again at the top-left corner.

You can try FlickrStreamr or download the source code and run it for yourself (you’ll need a Flickr API key though).
