    limited to hobbyists and concentrated in Japan where it was created Back then Ruby was virtually unheard of in the web development industry This changed dramatically when Rails was open sourced in 2004 and the marketing powers of the company DHH was working for 37signals propelled the framework along with DHH himself to global stardom at least within the web development world Never before had software development looked so easy The programming screen casts pioneered on rubyonrails org combined with the heavy usage of Apple s OS X even made the usually dull geeky world of coding look cool and exciting Classic wordy Hello World introductory tutorials was replaced by fancy Creating your own blog in 15 minutes screen casts This really transformed the web landscape and helped attract a new generation of web developers many of whom might not have ventured into web development otherwise Here s a list of websites I find useful for keeping up to date with the Ruby and Rails world Which ones do you find most useful Am I missing any good ones here Tutorials guides rubyonrails org railstutorial org Screencasts railsdispatch com rubytu be railscasts com Podcasts ruby5 envylabs com Webcasts confreaks com events Forums ruby forum com Blogs News railsinside com weblog rubyonrails org rubyflow com yehudakatz com railstips org blog rubyinside com Tags Coding Rails Ruby Permalink Leave a Reply Name required Mail will not be published required Website Comments Photos Flickr Widget requires Flash Player 9 or better More photos on Flickr Categories Coding 4 Conference 6 General 3 Linux 2 Multimedia 2 Rails 2 Sport 1 SUSE Studio 3 Travel 5 Web Services 1 Windows 1 Work 4 Archives April 2012 1 March 2012 1 September 2010 2 June 2010 3 May 2010 7 March 2010 3 February 2010

  • jam » Blog Archive » To Amsterdam and back
    Düsseldorf joined the long queue to get the train ticket waited yet another hour for the train to Duisburg and then the connecting train to Amsterdam which was of course 20 minutes late The trains were packed with disrupted air travellers like myself After standing in a hot and crowded train for 2 hours I finally made it to Amsterdam at 5pm instead of 10 30am Too late to catch the training session that ran from 1 to 6pm Returning from Amsterdam was painful too It started well managed to hitch a free cab ride to the airport and got there a whole 2 hours before departure time Flight was delayed by 30 minutes which is usually okay but in this case it made us miss the connecting flight in Munich despite our mad dash to the gates This turned out to be the last flight of the day 9pm and so we had to drive back home to Nuremberg Lufthansa gave us a voucher and told us to go to Sixth who then told us there wasn t such an arrangement Luckily Europcar just next door accepted the voucher and we were off in a Nissian Note 1 4 Two hours later we finally made it home just after midnight Tags Amsterdam Ash Fly Lufthansa Rail Permalink Leave a Reply Name required Mail will not be published required Website Comments Photos Flickr Widget requires Flash Player 9 or better More photos on Flickr Categories Coding 4 Conference 6 General 3 Linux 2 Multimedia 2 Rails 2 Sport 1 SUSE Studio 3 Travel 5 Web Services 1 Windows 1 Work 4 Archives April 2012 1 March 2012 1 September 2010 2 June 2010 3 May 2010 7 March 2010 3 February 2010 1 November 2009 1 Search Box Tags 2010

    at the Appliance Pavilion a bit more work there as it had a different video card so had to swap drivers Several hours later all preparations where done and we took the chance to pose with our mascot Dister Christoph and I posing with our mascot Dister Exhibition booths crowded with employees and attendees Stayed at Salt Lake Plaza hotel which is right next to the exhibition center Salt Lake City Capitol Hill as seen from the hotel window Unfortunately I did not have time to do any sightseeing in Salt Lake City Would have loved to take an afternoon off and wander the streets as well as to visit the Salt Lake Temple Also if I had known about the basketball game the following weekend I might have extended my trip there Well guess I ll have to do that next time Sunset from the hotel window Huge outdoor car parks seem to be the hallmark of many America cities Storm and Superman at the dinner party Batman and Beast from X Men were there too The major highlight for me was my demo of Studio together with Matt Richards Director of Emerging Technologies at the closing keynote With 2 000 attendees catching the keynote live you really want to make sure everything goes smoothly The demo system team did a great job coordinating the logistics and infrastructure thanks to Chris Neal and team All keynote presentations were recorded Behind the scenes look at what goes on backstage during the keynote Lots of monitors and control systems The rest of the pictures from Brainshare 2010 Salt Lake City can be found here Tags Conference USA Work Permalink Leave a Reply Name required Mail will not be published required Website Comments Photos Flickr Widget requires Flash Player 9 or better

    By spOt ON One nice thing about KL Putrajaya is that things are so cheap despite both being very modern cities For instance you can stay in a deluxe 40m sq room at the top notch 5 star Shangrila hotel for only 280 RM 70 EUR per night including complimentary Internet The hotel even has an infinity pool That kind of money can only get you a small room in old 3 star hotel or worse in Central Europe There is not much this area though so if you are there as a tourist it is much better to stay in Petaling Jaya or KL central around Bintang Walk It is a little more expensive but not by much and so much more convenient At the conference itself it turned out that we had the largest exhibition booth which was flanked by two large video screens I later found out that Novell was awarded the best exhibitor award for OSS showcase at the award ceremony held during the gala dinner which I unfortunately had to miss in order to catch my flight to Singapore Great job Jaslin and team Other than the usual manning of the exhibition booth I also had a presentation session introducing SUSE Studio I was told that the adoption of virtualization is still relatively small here particularly among government bodies so I just focused on the key concepts My session was right after the Friday keynote and there were three concurrent tracks so I wondered how the turn out would be like The keynote ended late and so I started after a delay of 10 minutes with attendees still milling in Pretty short slot 25 minutes so could not afford to wait too long Towards the end much more people attended the session than I expected they even had to bring extra chairs into the 200 seater hall The most interesting part was talking to the officials from Sudan in the audience who seemed genuinely impressed by Studio Session audience I was also asked to talk about Studio at the Birds of a Feather BoF session that evening It was somewhat of a letdown as not many people turned up Probably because it was pretty late on Friday evening and most people were eager to get started on their weekend Getting ready for the Birds of a Feather BoF session Dister Studio s robot mascot in the big screen It was a little challenging to get my point across as there were two other concurrent presentations which you can see in the background The crowd was dispersed and some just kept chatting among themselves Overall though it was a great trip and I had a wonderful time there working with the colleagues there The schedule was jammed packed but it gave me the chance to talk to a lot of partners and customers in the short time I have there Even squeezed in time for a press interview Tags Conference Malaysia SUSE Studio Read more Comments
