I was scheduled to give a talk on Stackato, ActiveStates micro-cloud solution, so I was quite determined to go on the second day. I did however take it slow and did not make it to the venue until 11:00, because I wanted to hear the talk by Peter Brodersen on Openstreetmaps.

Peter Brodersen is the man behind Findvej.dk, a service from the pre-Google maps of Denmark era. The map data came from Kort og Matrikelstyrelsen and was data, which previously was available for download, but now no longer is available for free.

Peter now works with OpenStreetmap (openstreetmap.org), which is a map of the world available under a Open Database License. It consists of both graphics and vector data.

Compared to Google maps its use is not restricted license-wise.

And some prominent companies and applications are now using OpenStreetMap data
- Foursquare changed to OpenStreetMap maps from of Google maps
- Apple uses OpenStreetMap data in iPhoto maps

OpenStreetMap operates with some basic data entities:
- Node – single geospatial point
- Way – ordered list of nodes, not necessarily a literal way
- Relation – ordered list of nodes/ways and/or relations
- tag – key=value pairs for all of the above

In addition a lot of meta data (speed limits, opening hours etc.), the project is open and can be regarded as a Wikipedia of maps of streets and related information.

Much of the Danish data part of the dataset are under a government license approved by Kammer Advokaten, and is compatible with Creative Commons and one others.

In general a really feel good presentation and Peter did a good job of presenting the topic. The use of OpenStreetMap in the public sector is expanding and the project is well respected and opens up for a lot of different uses, including many spin-off projects.

My fellow Perl Monger Mads Toftum did a presentation on Apache 2.4 and its new features. Apache is an awesome piece of software. Unfortunately Mads lost his presentation so the presentation was pretty basic and did perhaps not sell the new Apache version to well. Documentation on speed improvements would be nice since many of the new web servers such as nginx are very focused on this aspect.

Apache does however offer a lot of interesting features and some of the features replace old features and Apache is still a giant and contender in the web server competition. Comparing Apache to the other spiffy new web servers might let Apache look monolithic, old and slow and the release cycle and the Apache organization setup might also signal the same – this might not be the truth, but one of Apache’s future challenges could be one of image.

By the end of the day I did a presentation of ActiveStates micro-cloud Stackato, I will follow-up with a separate blog-post on Stackato. ActiveState had kindly donated a single Komodo IDE 7 license.

Being the author of the Perl module Games::Bingo I had implemented a Mojolicious based single number bingo app and deployed this on my Stackato micro-cloud. I gave the people in the room numbers and the winner was one of the organizers of CloudCamp Copenhagen. She was so kind as to invite me to give a lightning talk at CloudCamp Copenhagen, which is a part of the GOTO Copenhagen Software development conference, where I am participating anyway – so this I am looking very much forward to.

Congratulations to Maja with her Komodo IDE 7 license and congratulations to all the people involved in Open Source Days with yet another successful conference.

So please read the Call for Speakers below and forward it to friends, colleagues, fellow Perl mongers and anybody who could be interested.

I am evaluating if any of my talks given to the Copenhagen Perl Mongers through the last year would make could candidates for Open Source Days 2012.

Open Source Days 2012: Call for Speakers
========================================

Open Source Days 2012 is currently planned for early March 2012 and we are
looking for gifted, entertaining and technically enlightened speakers for the
conference.

The conference itself will take place the 2nd and 3rd of March and training
will be available 1st of March.

Training courses – Half or full day
———————————–

As something new we will want to try out longer training courses – half or full
day, held on the day before the conference itself.

We are looking for both subjects and instructors.

Since we expect the course participants to pay for the training, we are willing
to pay the instructor for giving the course, provided that a sufficient number
of people sign up.

Naturally the course instructors also get free access to the conference, since
we also hope to get a normal talk out of the instructor.

Normal Talks – 45 minutes
————————-

This year we will have a track with focus on the use of open source software in
newly created startups and another track with focus on green technologies.

Non-startup related talks are also of interest and we’ll try to fit them into
various related tracks.

Speakers can attend the conference free of charge and to some extent we might
be able to reimburse your travel and hotel.

Lightning Talks – 15 minutes
—————————-

Talk about anything you like. Tell us about your idea for a new project, how
you made your first Qt application or something completely different. For
lightning talks, only your imagination and the timeframe are the limiting
factors.

If you have never tried doing a presentation before, but are working on
something you believe other people might find interesting, then this is a good
opportunity to start.

Lightning talk speakers can attend the conference free of charge.

Sponsorships
————

Sponsorships can be in the range of DKK 10000 and up. Please write to
sponsor2012@opensourcedays.org if you are interested in becoming a conference
sponsor.

Your sponsorship could, for example, be used for:

* Provide a conference T-shirt.
* Provide lunch for the participants.
* Provide key hangers.
* Provide a conference bag.
* Provide a conference beer event.

Exhibition Booth
—————-

If you are interested in an exhibition booth, you can also contact us at the
sponsor2012@opensourcedays.org.

Hackerspaces and Community Booths
———————————

More information about these will follow once we get closer to the conference.

Contact Information
——————-

Please, send us a title, a short description and a short biography of yourself
to program2012@opensourcedays.org no later than January 21st, 2012.

You are also most welcome to contact us if you have any questions regarding the
conference itself. You can also catch most of us in the IRC channel
#opensourcedays on the EFnet IRC network.

Feel free to follow us on http://twitter.com/opensourcedays or

conference.
