After looking at The Wilderness Downtown, a fantastic Chrome Experiment, I felt like I had to do something similair! Three hours later (first time experimenting with Google Maps and Street View) the result is below.
It is nothing like The Wilderness Downtown, but still I’d like to share it ;-)
Enter streetname, town and country:
Yes, there are a LOT of bugs… And no, I’m not going to fix them, so there is no need to notify me.
Wow, just wow…
Thanks a lot for all your support people, it’s great to see and read I’m not the only one to think this situation isn’t normal.

Some time ago I received the following email about this project.
Mr. van Rijn,
I am Darren Briggs, the Chief Technical Officer of Landmark Digital Services, LLC. Landmark Digital Services owns the patents that cover the algorithm used as the basis for your recently posted “Creating Shazam In Java”. While it is not Landmark’s intention to alienate those in the Open Source and Music Information Retrieval community, Landmark must request that you do not ship, deploy or post the code presented in your post. Landmark also requests that in the future you do not ship, deploy or post any portions or versions of this code in its current state or in any modified state.
We hope you understand our position and that we would be legally remiss not to make this request. We appreciate your immediate attention and response.

This scared me a bit, why are they emailing me? I’ve written some code (100% my own) and implemented my own methods for matching music. There are some key differences with the algorithm Shazam uses.
After a comment on my previous blog entry (about creating a shazam clone) I started tinkering again.
Somebody asked: Could this be used to detect duplicate songs in my mp3 collection!?
That is exacly what I just tried!
Here are some examples:
Duplicate found: 01 - everything in its right place.mp3.song matches with D:\data\v2\01-radiohead-everything_in_it’s_wrong_place-h8me.mp3.song and score: 134
(note: This is a remix of the original, with some rap mixed in)
Duplicate found: 01 - Joy Division - Exercise One.mp3.song matches with D:\data\v2\114 - Joy Division - Exercise One (From Still).mp3.song and score: 255
A couple of days ago I encountered this article: How Shazam Works
This got me interested in how a program like Shazam works… And more importantly, how hard is it to program something similar in Java?
Shazam is an application which you can use to analyse/match music. When you install it on your phone, and hold the microphone to some music for about 20 to 30 seconds, it will tell you which song it is.
When I first used it it gave me a magical feeling. “How did it do that!?”. And even today, after using...
Yesterday, while browsing DZone, I encountered a couple of HTML 5 blogs. So I decided to try and code some HTML5 - Canvas myself.
This is the result of one hour trail-and-error:
Sorry, no support, please upgrade your browser!
Maybe I’ll do a write-up soon, but for now, just check the sources. (Yes they are wrong/hack-ish, I know…).
Here are (in my opinion) five of the most important ‘rules’ in software development.
The reason why waterfall doesn’t work and agile works a lot better. Changes happen. People will always change their mind, over time technology changes and situations change. So during software development you will have to be flexible with the requirements.
Create software that the client wants, not what he says he wants.
What the clients tells you he wants might not (entirely) be what he/she actually wants or the organisation needs. It is vital to ask questions and release early. When you...
The last couple of weeks I have been playing around with compression/decompression algorithms. This is a field that has always intrigued me. It gives me a magical feeling, like a magician you wave some algorithm around and suddenly the files shrink and bytes dissapear. With the same motion you can undo all your actions and re-generate the original files from thin air!
Arithmetic coding is a different method to encode bytes. On itself it doesn’t compress, but it is the backbone of a whole family of compression algorithms. To explain how it works we need some example...
Its a problem I encouter in most JEE projects I’ve worked on so far. Handling null-values. But why is this a problem? And what strategies can we follow to reduce the problem? That is what I’m trying to find out in this post.
Lets start with a piece of business logic, in a world where we don’t have null-values:
This looks good and understandable! But this isn’t what I see in most projects. Usually I see code like this:
Wow, that is not a pretty sight, not at all! What can we do about it and how did it happen?
For the Queue ICPC programming game Capture I ran into a geometrical problem.
While programming my little robot I wanted to have an algorithm calculate this for me:
- I have a field with 122 points
- I have a circle of fixed size
How do I calculate where to put the circle so it encapsulates the most points?
This is what I came up with, three algorithms:
Algorithm #1: Centerpoint
The first algorithm was created as a test. It doesn’t find the perfect solution, but gives a decent solution.
First I loop over all the...
- Why, when one color has run out of ink, you can’t print anything!?
- Why does a pencil cost $0,50 and does an ink-cartridge cost $30,-?
- Why does a pencil still work after 5 years and is an ink-cartridge completely dried up?
- Why is a new printer (including ink cartridge) sometimes cheaper then a seperate ink-cartridge (crazy!)
- Why do printers eat paper for lunch?
- Why is printer-software so invasive? What happened to a simple ‘driver’
- Why does most hardware run perfectly under Linux, except printers?
Screw this, I’ll just mail my report instead of printing it…
Recently I placed a comment on this interesting blog from Uncle Bob Martin (Robert C. Martin). It contains a brief description on how I teach people how to use the Spring Framework.
Now, by popular demand (one person requested it over Twitter), I’ll guide you through the method and examples I use in this blogpost. It explains why people should use frameworks like Spring and/or Google Guice, and how.
Lets take a look at the application we have. We have a service:
What if your favourite movie was remade as a porn movie? How would it be called, what would the title be?
My collegues and I were discussing this, and we came up with a top 10. We’ve also started a twitter hashtag.
- Shaving Ryan’s Privates (everybodies favourite)
- The Curious Taste of Benjamin’s Bottom
- Honey, I shagged the kids
- Missionary Impossible III
- Good Will Humping
- Free my Willy
- Legally Boned
- I Know Who you did last Summer
- Schindler’s Fist
- Cliff Banger
And some honourable mentions to the titles that just didn’t make...
Why does my car do this to me? It bugs me everyday. When I drive with the snow outside I have to use my windscreen washer quite a lot. When I pull the little lever behind my steering wheel it spurts a jet of antifreeze/washer fluid onto my screen and it starts to wipe for about 10 times. Then it stops… my window is clean again!
But after about 15 seconds it does one final sweep… and this last sweep always leaves ugly marks!
Why do cars do this!!!? First it cleans my...
