  Hackers, Makers and Geeks in Lisbon 

  As I mentioned in my previous post, I have some friends who are not applying to SeedCapital because they are by themselves. Unfortunately there isn’t yet a place where people can see what projects are in need of more people. It is also not that easy to meet someone on-line to work together. We need a certain trust in that person, etc.

  I think the best way to meet people that are interested, smart and have initiative is to attend one of the many hacker events that are held monthly (or at least regularly). In Lisbon we have several of them:

  Twittlis – monthly meeting of twitter.com users in Lisbon

  AltLab Hackerspace Lisbon

  Lisbon Perl Mongers Group
  http://lisbon.pm.org/

  Comunidade Portuguesa de Rich Internet Applications
  http://www.riapt.org/

  Lisbon Ruby Group
  http://www.ruby-pt.org/

  Gathering of Developers
  http://god.pt/

  One Over Zero Group

  Do you know of any other groups?

  Update (13/12/2009): Since this post I’ve found out about the following groups:

  XAMLPT – Comunidade Portuguesa para Tecnologias de Apresentação da Microsoft: WPF, Silverlight, Surface
  http://www.xamlpt.com

  Ignite Portugal

  Portuguese Ubuntu Community

    Unfortunately I don’t know any. I would be interested in such groups but not only in Lisbon. Portugal has Hackers, Makers and Geeks also outside Lisbon, some of them are truly good ones and other truly bad ones, like in Lisbon :)

    Can’t understand why we have so many Lisbon Groups and not Portugal Groups instead.

    btw, It’s not Lisbon Ruby Group, it’s portuguese ruby group. we co-organized some dinners in Coimbra and Porto.

    I think it’s just a mather of audience, if enough people organize stuff outside of Lisbon, the rest of the community will mostly follow (ex: takeoff, barcamp).

  Ruby on Rails Scalability 

  Last week I was talking with @lofih and he was going on about how Ruby on Rails doesn’t scale very well.  The question is when you have millions of users hitting your web application, how well does it cope with it? So I went and searched for scalability with Ruby and Rails and read a bit about it. Following are some notes of what I’ve found.

  This seems to be in the discussion panes for some years now. There is a particulary interesting e-mail from Rails creator, David Hansson, on scalability (scroll down for David’s part) here:

  http://pylab.blogspot.com/2007/02/scaling-rails.html

  I guess the discussion was brought to life again after Twitter (which is Rails based) being down for a few times and one Twitter developer saying: “there’s no facility in Rails to talk to more than one database at a time“.

  But this was quickly addressed by Nic Williams releasing a gem called “Magic Multi-Connections” a few days later. In his words: “It makes it dead easy to use a cluster of databases to scale read and write speeds higher than a single connection would ever allow.”
  

  http://magicmodels.rubyforge.org/magic_multi_connections/

  Another interesting reading seems to be the book “Building Scalable Web Sites” by Cal Henderson, lead developer for Flickr.

  http://www.amazon.com/Building-Scalable-Web-Sites-applications/dp/0596102356

  It’s fun fun fun this kind of applications and challenges. I mean 2.2 million users hitting your server, what do you do? And most of all, how do people start these companies? In Europe it seems to be all about the same old boring software companies we had 10 years ago. Where are the opportunities to work in a real Internet company in Europe?

    Well i give in that rails has a thriving community and most issues do get addressed quite fast, however it still strikes me as something that i wouldn’t choose in a big project without heavy modification.

    As for the sexy internet start-ups, you know what they say, if you can’t find one, let’s build one! (and it’s an offer ;) )
