Posting links from delicious to Blogger
I collect quite a long list of links while I “surf the web”. Until now I’ve done the Mixed Links series, but I’ve been looking for ways to automate it. Enter delicious (or del.icio.us as it was formerly known): it has a nice Firefox plugin and theoretically it can post your bookmarks automatically to your…

Adding a world clock to your blog
Quite some time ago I’ve written a post about how to create a clock which shows the blog author’s time zone. The intention was to make relative temporal references (like “tomorrow”, “yesterday”, “within the last hour”, etc) more relevant to readers from different timezones. While the method worked perfectly, it did require you to have…

MMassively Parallel Computing 🙂
I am a fan of BOINC, which uses distributed computing to solve massive problems (some very serious, like finding a cure to certain types of cancer, others more abstract, like finding prime numbers). The problem however is ease of use and distribution. You have to (a) know that this software exists and (b) know how…

Update to the Top Commenters widget
Some time ago I created a "Top Commenters" widget for Blogger using Yahoo Pipes. Unfortunately my efforts to use the resulting RSS directly failed. The problem was that Blogger was displaying older entries, even though I tried a bunch of different things to convince it that the element were new (like setting the date, adding…

Watch out for long running tasks with Java Timer
The problem? Write a code which will execute every N seconds. The solution? Using a Timer with scheduleAtFixedRate. Now you got two problems :-), unless you’ve carefully read the documentation which states (emphasis added): If an execution is delayed for any reason (such as garbage collection or other background activity), two or more executions will…

I thought: surely, there is a simpler, documented way to do that. Now, the following code was written in…

Javascript regex quirk
When I’ve written the SMOG analyzer javascript I found a quirk of javascript and this recent post inspired me to share it: The javascript regex specification doesn’t have the s modifier. This is necessary when you want to match multiple lines with a construct like .*. The suggested workaround I found was to specify the…

Everything old is new again – SMOG
Warning! The site which the script uses to provide the service contains a malicious iframe. While most probably the site itself is not malicious, I don’t recommend using the script below until the issues have been cleared up. If you included it in your site, please disable it until the problems have been cleared up.…

Restarting scripts in Opera after you stopped them
Opera has a nice feature, whereby each message box created from a Javascript offers you an option to stop running scripts for the given page. This is very nice if you are using alerts to debug your script and you’ve just realized that you have created an infinite loop by mistake :-D. However, once you’ve…
