Where was CamelCase invented?: In Scottland

They attached a sensor to the wheel of a hamster and plot the distance using Google Maps to see if it is possible that a hamster runs all across America in his lifetime.

Title: Ruby On Rails I18N Developer
Skills: I18N, Ruby on Rails, mySQL
…
Job description:
…
Chumby Industries is looking for a Ruby On Rails/I18N Contractor to deliver results for the internationalization (I18N) effort on the server.
This candidate would be responsible for externalizing all the text strings (both static and dynamically generated) that the website uses so that Chumby could later change the language of the site based on location.

Skills required:
Previous I18N efforts on browser-based platforms
Strong web-based development experience
Ruby on Rails experience
mySQL database experience
Familiarity of layout issues involved with I18N

My experience so far was great.

Step one: configure WiFi
It detected my local network without a problem. I had to enter the password and was ready to go.

Step two: activate chumby
Create an account at chumby.com and click on “activate chumby”. It shows a 4×4 matrix of dots you have to copy to your chumby to connect you account with your device. This is a nice idea. It’s very simple, easy to use but effective. And surprisingly that’s it.

Step three: add widgets
Just one click. Sometimes the widgets need a some configuration but everything is explained right there.

Minor annoyances

• only two brightness settings: high & low
• you have to press pretty hard on the touchscreen

Plans:
Find a German power supply (should be easy) and start coding a widget

We used Kara to teach them a little bit about programming. You can create finite state machines to control a bug which runs around and tries to solve different problems. The girls did much better than I expected and finished all the exercises we thought would be enough for a whole day before lunch.

Without much preparation I decided to teach them a little about “real” programming and Ruby because there is a Ruby version of Kara which lets you write Ruby code to control the bug.

The experiment was very successful. The girls solved all the problems again, this time in Ruby and from their feedback they really enjoyed it.

A couple of years ago I taught a programming course for kids at the Volkshochschule in Karlsruhe. At that time I used Perl (it was a loooong time ago and I didn’t know Ruby then) but if I ever do this again I will use RubyKara.

They will host a recruiting event called “nerd night” in Karlsruhe and have put a registration URL on the flyer for www.nerd-night.de. Does it work? No! At least yesterday and today it didn’t. It redirects to http://www1.1und1.de/index.php?page=faq. Yet another professional piece of work from a web hosting company. I guess it was yet another campaign that had to go online on a Friday afternoon.

Update:
The page is finally online. And it contains gems like “Wir sind das Internet.” (We are the internet). Arrogant? Brave? Dumb?

What’s the problem?

I’m a nba fan and I subscribe to the NBA.com RSS feed (http://www.nba.com/rss/nba_rss.xml) which works fine most of the time but sometimes I get an empty page. Why? Because some lazy developer thought it might be a good idea to add ?rss=true to every link.

If you look at todays feed you can find this item:

<item>
<title><![CDATA[Cavs' Gibson Expected to Miss Four to Six Weeks]]></title>
<link><![CDATA[http://sports.espn.go.com/nba/news/story?id=3255778?rss=true]]></link>
<description>...>
</item>


If I follow the link ESPN returns:

<!-- obj null -->


The suffix ?rss=true appears after every link in the feed so I’m pretty certain it’s not ESPN’s fault…

Update:

It’s even better. Not only do they destroy external links by appending ?rss=true, they kill their own links, too:

<link><![CDATA[http://my.nba.com/thread.jspa?threadID=300025597?rss=true]]></link>


Things to do:

• Watch and try everything from NXT Tutorial.
• Try Ruby-nxt. The project seems stale because status is still alpha and last update in November 2006. I would love to use my favorite language to control the robots I’m going to build.
• Have a look at the NXT firmware.
• Look at all the other ways to program the NXT.

I’ve remove my caps-lock key from a couple of keyboards already. But I did not know that a campaign called anticAPSLOCK existed which tries to ban caps-lock from future keyboards. Nice idea!

ps: I watched Seattle Conference on Scalability: Lessons In Building Scalable Systems, an older talk called A New Way to look at Networking and Haiku: The Operating System

First I read amazon.de Help but I found no phone number. Then I checked Imprint, where I found a link label Callback service. Less than a second after I entered my phone number, my phone rang. Less than 30sec later I was explaining my problem to a customer service person. I was really suprised as he told me something like “the card is in stock, you will have it tomorrow”. Me: “What?!?” Him: “Yes, I will send it by express. 99.9% of the packages are delivered the very next day.” Me: “Cool, that’s great. Thank you VERY MUCH!”. And for the happy ending the package did arrive today Thank you, Amazon!

There is a CafePress shop for RubyHacker stuff with a few nice thingies. But I wanted something else

A shop (fotokasten.de) sells all-black mugs which only reveal the image when something hot is inside. Therefore I needed my own RubyHacker image and couldn’t find one online. To save everybody else the work, here’s my result.

I will post images of the mug when I have it

Update:
I made a mistake and put the wrong image online. Fotokasten does not accept gif (which is pretty lame but I cannot change it). Changed the image to a jpg.
