The Next Web Startup Rally

yunoo StartupsLast year over 250 startups signed up for The Next Web Startup Rally. After multiple jury rounds the 24 finalists we’re selected to present on main stage during The Next Web Conference. This changed the lives of many entrepreneurs. And thanks to last years Startup Rally sponsor Sun it was free of any charge for the Startups.

This year it is the fifth edition of The Next Web Conference, it is a special year for us and we’re reinventing ourselves by raising the bar again. Behind the scenes we’re working on an even bigger and more prestigious Startup Rally then last year.

I hope to see you all there but in the meantime enter The Startup Rally now

Who uses MySQL triggers for Application Refactoring ?

Here's a technical question which we have been asked by Panthermedia.net a Sun Startup Essentials member:

Panthermedia is currently refactoring the entire application including the database and it's schema. Panthermedia needs some time to do this. Panthermedia decided to do a step by step mgration for all modules. They decided to follow an innovative approach:

  • They created the new database tables in parallel to the existing ones
  • The old tables got update triggers which maintain the correct state in the new tables for every "old" query going to the old tables
  • The new tables got update triggers which maintain the correct state in the old tables. "New" queries use the new tables
  • The application is now getting re factored in a step by step approach. More and more new components use the new tables
  • Panthermedia is currently using MySQL 5.0.68 including master/master replication plus replication for backup purposes.

The current approach works like a charm. The questions is however if other members used this approach before. What are the up- and downsides?

Please let us know and start a discussion through the comment function!

Before I forget!:

Panthermedia.net is an online marketplace for royalty-free photography. Buyers and sellers of royalty-free images meet on one common platform. This platform is divided in a photo community for photographers and a stock agency for art buyers.

The photo community serves as the creative heart of the marketplace. Semi-professional and hobby photographers from all over the world can submit images to our site, communicate and interact with other members of the community, share their knowledge and experiences, and sell their images. The goal is to provide an environment where photographers can develop their artistic potential.


The founders Robert Walters (l.) und Peter Ammel

The editors at Panthermedia.net select images for our archive. The licenses for using these images for editorial or commercial purposes are offered in the stock agency. The primary target group are small and medium-sized agencies, publishers and companies working with a limited budget. Our team of sales representatives support customers in their search and selection of images. We have created an easy and affordable pricing structure that is significantly below regular prices for professional royalty free images.

Panthermedia.net is an enterprise of PantherMedia GmbH, located in Munich, Germany. The company was founded in October of 2004.

Using Virtualization for Securing MySQL

For those of you using MySQL, I just posted an article on how to secure it using virtualization features from OpenSolaris. The solution described can help in the face of a denial-of-service (DoS) attack.

Tweetminster - New Search Engine - A great #sunstartupessentials customer


Tweetminster, the media utility that connects people to UK politics has recently launched Tweetminster Search– a sentiment engine to measure the pulse of UK politics in real time.

Tweetminster Search is a new way to find, interact with and make sense of information that matters.

The search engine shows users how people feel about the issues of the day - as expressed through the thousands of messages posted to Twitter by politicians, news sources, journalists and the public.  Tweetminster Search works in real time, it shows what people think now, and tracks how their sentiment has changed over time.

Once entered a search term (eg. Iraq Inquiry) or up to three multiple terms (eg. Labour, Conservatives, Lib Dems) – users are provided with:

    \* The number of relevant tweets about the subject over time (frequency)
    \* How these tweets break down into positive, negative and neutral opinions (sentiment)
    \* How many people have been reached through tweets about the topic/s (visibility)
    \* The individuals with the most impact on the subject (influencers)
    \* Plus lots of related information - associated terms and issues, links to relevant URLs and a location breakdown for where the terms are being discussed the most.


Alongside terms, users can also analyse Twitter usernames or a combination of elements. For example one can analyse the correlation between a topic (e.g. Tax cuts) and user (EricPickles).

The search engine also allows users to view and filter the tweets behind the results by party, source, politician, time, and also uses Twitter Lists to display livestreams of tweets by MPs, PPCs and journalists, bloggers, news sources and key influencers.

Tweetminster Search is designed to only analyse relevant content which is what makes Tweetminster Search different.  The technology defines relevance by determining the originality (for example a tweet may generate many RTs, Tweetminster includes the original tweet in its analysis), influence and reach of a tweet - so it doesn’t try to analyse all of Twitter, but only the content it determines that matters.

Tweetminster Search is currently in beta. Alongside tuning its performance, we will be adding new features, including more granular control of the data, additional data and content sources and more advanced filters, plus will soon release an API to allow anyone to access, use and manipulate the raw data.

Tweetminster is a Sun Startup Essential customer and is hosted at everycity on Sun hardware and the Solaris OS, to enable it to scale and give real time speed.
