Setup T-Mobile GPRS on OSX with Nokia N80 and bluetooth

Since I had a hard time finding useful information on setting up a Dutch T-Mobile GPRS connection over bluetooth on my MacBook (OSX 10.4.9), I thought I’d share my findings.

Make sure you have your phone and Mac paired over bluetooth. Also, make sure that you actually have a GPRS connection (try email or browsing on your phone). The following was how it worked for me with a Nokia N80 phone:

- Get the modem scripts at http://www.taniwha.org.uk/ (note: pint-ware!)
- Unpack the scripts in /Library/Modem Scripts/
- Open System Preferences -> Network -> Show Bluetooth
- In the PPP tab, only supply the Telephone Number as internet.
- Optionally, also provide a Service Provider, e.g. T-Mobile Internet)
- In the PPP options, make sure that Send PPP Echo Packets is disabled
- In the Bluetooth Modem tab, select the right modem (I chose Nokia 3G CID1)
- Back in the PPP tab, hit Dial Now…

That’s it. Enjoy!

Maemo Mapper supports OpenStreetMap

Maemo Mapper now supports OpenStreetMap as a map repository. This makes it the first really legal repository, also to be used for off line viewing.

Scroll wheel zoom inconsistency between Google Earth and Maps

I just noticed that scroll wheel zooming in Google Earth works the exact opposite in Google Maps.

Scrolling forward in Google Earth is zooming out. Zooming out in Google Maps is done by scrolling backward.

I like the Google Maps behavior better. You?

Webical template styled … what lies ahead?

From the Webical project page:

We have just deployed a new Webical snapshot on the demo:
http://demo.webical.org

As you can see, work has been put in styling the default template. Most overview pages and details pages have been consistently styled and should work correctly. And lots of bugs have been squashed.

The current focus is on finishing the regular (accessible forms based) version. This includes making the style consistent across all pages and fixing any obvious bugs from user interface down to synching the iCalendar data. Once this is finished, we’ll release a Webical which contains the MUSTHAVES.

Focus then will then move to finishing the AJAX (juicy drag ‘n drop) version. After that, all Webical SHOULDHAVES are done.

What comes next is implementing plugins using the plugin framework. This is a pretty cool framework that makes it possible to extend the Webical calendaring platform with:
- front-end plugins (e.g. Google Maps integration, Weather integration, additional views, etc.)
- back-end plugins (e.g. CalDAV persistence, Database persistence, etc.)
- templates
- localizations (English and Dutch are already included)

So, please check out the demo and post any (style) bugs in the trackers! And join the mailing list to discuss further development.

Join the OpenStreetMap Amsterdam mapping party

For those of you based in the Netherlands and interested in collaborating on creating free (as in speech) maps, consider joining the Amsterdam mapping party on March 17/18th.

We’ll be biking and hiking across the centre of Amsterdam, collecting tracks, which will be followed by creating streets behind a computer. Drinks and work space are provided for by Func.

Record GPS tracks with your mobile phone

Tommi Laukkanen has created just the application that almost scratches my itch: Mobile Trail Explorer.

It is a Midlet that runs on your mobile phone and records your tracks. You’ll need a bluetooth mouse (I’m using the i-Blue) and a mobile phone that supports Java MIDP 2.0, bluetooth connections (JSR-82) and file connections (JSR-75) extensions.

My Nokia N80i does :)

I mentioned ‘almost’ because the export function only supports KML. Which is nice in itself, but if you want to use it for anything else, GPX is the way to go. I’ve posted an enhancement issue.

update: I’ve just created a simple hack that convert the resulting KML into GPX :)

Mapping Amsterdam with Open Street Map

I have finally jumped into the whole Open Street Map thing. Currently I am scratching my own Amsterdam itch. Believe it or not, but Amsterdam was virtually non-existent in OSM, so I started the Amsterdam topic.

The data acquisition is fun to do … biking different detours to work and recording every car ride.

To give you an impression of Amsterdam before and after I started (different viewpoints and renderers):

The people behind OSM are acquiring funds in the Netherlands in order to jump start the community here (currently at about 5 users).

Do you feel like helping out on building a free map of the world? In March we’ll do the first Amsterdam mapping party!

update: nl.wikipedia.org entry added :)

Geni – Everyone’s Related

Geni lets you create a family tree through our fun simple interface. When you add a relative’s email address, he or she will be invited to join your tree. That relative can then add other relatives, and so on. Your tree will continue to grow as relatives invite other relatives.

Each family member has a profile which can be viewed by clicking their name in the tree. This helps family members learn more about each other and stay in touch. Family members can also share information and work together to build profiles for common ancestors.

Geni is a private network. Only the people in your tree can see your tree and your profile. Geni will not share your personal information with third parties.

Well, go check it out.
