Cowbell++;

Posted on 2008-08-07 By rolfje 2 Comments on Cowbell++;

I just came across this great post about creating captivating content. The punchline: It’s not about getting the scoop, it’s about finding the cowbell and amplifying it.

More funny cowbell references:

  • Alex Johnson’s version the popular playstation game.
  • The wikipedia page on the cowbell sketch
  • The Cowbell project
  • And… The More Cowbell app for your iPhone (rock on!)

If you’ll excuse me, I’m going to “explore the studio space”. No, really. 🙂

Apple I Basic Reconstructed

Posted on 2008-08-05 By rolfje No Comments on Apple I Basic Reconstructed

Feast your eyes on this:

0000010 23 a9 a0 85 e4 4c c9 e3 a9 20 c5 24 b0 0c a9 8d

It is the first 64 bytes of the Apple I Basic, as reconstructed from tape by Michael Steil. You can read all about how he did this on his blog. A nice read for the people out there who can still remember putting tapes with strange sounds on it into the computer.

Laptop Stolen? See who did it…

Posted on 2008-08-04 By rolfje No Comments on Laptop Stolen? See who did it…

In this strange world, people can’t seem to leave your stuff alone. All the electronic gadgets of today are too attractive to the lowlife of this world. So what do you do if somebody swipes your laptop? You take a few pictures of him, and trace his IP address!

No Exclamation Please

Posted on 2008-08-01 By rolfje 8 Comments on No Exclamation Please

Some developers nowadays still think that putting an exclamation mark in their log entries adds to the visibility of their entry. When other developers notice this, they will add even more exclamation marks so their log entries are even more visible. I compiled a few examples of bad log entries and some pointers for you to improve your log entries.

The Process

Posted on 2008-08-01 By rolfje No Comments on The Process

When working at a Software Company, every now and then you need to do requirements workshops. You can’t imagine how close the following video comes to the truth. Thanks to Seth’s blog.

The Manualist

Posted on 2008-07-25 By rolfje No Comments on The Manualist

There’s a funny comercial on Dutch television which says that you should be paying too much for all the rubbish you download on the internet. Here’s a nice example of stuff you don’t want to pay too much for 🙂

It may look silly, but this guy actually had to be practicing a lot to get to this (Mario) level.

Spring SystemPropertyInitializingBean

Posted on 2008-07-23 By rolfje 8 Comments on Spring SystemPropertyInitializingBean

When using POI in any of your projects, and the application you’re building is a web application, you probably have it running on a Windows machine. If not, you know all about the struggle with the “headless mode” environment setting to tell the JVM how to handle graphics rendering.

I always like to keep my applications as clean as possible to the users. The system administrator is also a user of the software (during installation at least). So I wanted the application to set the environment properties itself, In this case, I built a nice little Spring bean to handle this. The solution is so simple, that it is almost a brilliant display of what Spring can solve for you. Suddenly, all these environment setting problems turned into a simple Spring configuration problem. Here’s how:

Ibatis 2.2 Ignores XML encoding

Posted on 2008-07-20 By rolfje No Comments on Ibatis 2.2 Ignores XML encoding

At my company, we’re using Ibatis to do operations on Oracle databases. As most of our software is designed to be international, we keep our XML files in UTF-8 encoding. Recently we discovered that Ibatis had some trouble parsing the XML files when we were using diacritics in them. As it turns out, Ibatis 2.2 actually ignores the “UTF-8” setting in the XML file header altogether.

This was actually reported as an issue at apache’s issue tracker, and fixed in Ibatis release 2.3 and upward. In the meantime, if you can not swich to a new release because of tight deadlines and no time for regression tests, you can set the file.encoding property to UTF-8, because then Ibatis will parse the XML in the correct encoding.

Tomcat, UTF-8 and the RequestDumperValve

Posted on 2008-07-20 By rolfje No Comments on Tomcat, UTF-8 and the RequestDumperValve

A week ago, we encountered a funny problem where our Tapestry 3.0 application seemed to screw up the encoding of form posts. Every time we tried to post a form with diacritics in the input fields, the data got mangled before reaching the application code.

As it turned out, somebody had turned on the RequestDumperValve in the Tomcat configuration file. The request dumper does not only dump the request, but is also kind enough to mangle the data before handing it over to the servlet for further processing:

Conform Specs is not enough

Posted on 2008-07-12 By rolfje 3 Comments on Conform Specs is not enough

Like any good software company, when a project starts, we sit down with the client, and talk about what we can do to help. The result is usually a more or less complete SRS (Software Requirement Specification). The SRS serves as input to the design fase (we usually already have an architecture sketch when the SRS is made) and those two documents are used to brief the developers and keep everybody posted on what to build. If all done correctly, this should then result in a perfect piece of software right?
