Shane McIntosh gave a very good and visual lightning talk about the supposedly dry topic of "Identifying Hotspots in Software Build Processes" at FOSDEM.

Identical to this test but with the following differences;

It was the first time, when all developers finally seen each other after more than 10 years of joint work on PostgreSQL.

OpenGroupware.org is an Open Source collaborative software (groupware) server for multiple clients. It is mostly written in Objective C and uses PostgreSQL and Apache. OpenGroupware.org is built on code released in 2003 by SKYRIX Software AG, it represents a product that has been under development since 1996.
OpenGroupware.org differs from many other groupware offerings in that it is not only a suite of bundled collaboration applications but focuses on providing a platform for groupware solutions through the use of standard protocols and XML based APIs. Accordingly projects to support clients such as Kontact and Novell Evolution via GroupDAV, are either complete or underway. Synchronization of mobile devices is supported via BionicMessages' GroupDAV connector for the Funambol DS server. The zOGI XML-RPC API enables easy integration with existing custom applications. OpenGroupware.org has been used as groupware platform to build CRM and scheduling solutions in conjunction with other Open Source software including LAMP and Mono.
Development of the Novell Evolution connector was arranged by Toltech Solutions.

A commercial edition is also available that adds Oracle Corporation support and load-balanced clustering. Microsoft Outlook support is provided via commercial client and server add-on known as Zidelook. All features besides Oracle Corporation support, clustering, and Microsoft Outlook support are provided in the Open Source edition; this includes XML-RPC, web interface, GroupDAV, CalDAV, and iCalendar.
OGO (Outdoor Gravity Orb) is the latest adventure activity to hit the United States. The OGO is a ten foot ball with a six foot interior ball that is used to ride down hills. If you close your eyes and imagine being in a hampser ball sized for humans you will now have a good mental image of The OGO. There are two ways to Ride The OGO;
First, you can ride the H2OGO. The H2OGO has five to ten gallons of water added to the interior ball, up to three people dive into the ball and ride down the hill for one of the craziest experiences ever. It has been described like being in a washing machine and a roller coaster at the same time. The great part about the H2OGO is that all family members can enjoy the ride. Mom, Dad, and a kid; Mom and two kids, everyone of all ages have the same emotional journey of laughter and exileration. To see some crazy video footage from inside The OGO and meet the man behind the company.[1]
The second way to ride the OGO is to get strapped into a harness that centralizes the weight and flip head over heals, seeing grass, sky, grass, sky as you ride down hill. The single harness OGO is called the IGO and consists of a seven point harness system, securing both feet, shoulders, waist, and grips for both hands. Considered by many to be as close to orbiting in space as you can get. And if that sounds crazy, don't just ride by yourself, ride with a friend the in the first 7 point double harness which is called the WEGO.
To get a better handle or idea of the latest adventure activity for all the family, go to the Outdoor Gravity website. The first OGO Park in the United States has been constructed and is currently open just north of Boston in Massachusetts, at The Amesbury Sports Park.
This will make it faster to perform intersection and other comparison queries on GIS data in a PostgreSQL database.

Alvaro Herrera, Teodor Sigaev, Markus Wanner, Jean-Paul Argudo, Dimitri Fontaine after night walk in Toronto
James drove two hours to Ottawa just to pay me a visit during the conference. Thanks James, was great to see you!
This is the same picture (www.flickr.com/photos/obartunov/7212940906/in/set-7215762...), but with Alvaro Herrera on the right side.
It's also available in high-resolution !
Teodor Sigaev (SAI MSU, mail.ru), Asko Oja (Skype), Oleg Bartunov ( SAI MSU), Marko Kreen (Skype). Ivan Zolotukhin (SAI MSU) made this shot.
We (Alexander Korotkov, Teodor Sigaev, Oleg Bartunov) are major PostgreSQL contributors. Building a company.
Heroku.com sponsors boat trip on the Vltava river. I made this shot of EnterpriseDB people - Bruce and Christine Momjian, Radhika Samant (CFO), Ed Boyajian ( President and CEO). Bruce Momjian is a Senior Database Architect at EnterpriseDB and member of core team of PostgreSQL. I know him since 1996 or so and we both are senior member of PostgreSQL development team.
EnterpriseDB has supported me and Teodor Sigaev to work on built-in full-text search in PostgreSQL in 2006.
In the next few years, when Postgres will have the cluster solution(s), this picture will remind all of us this cluster meeting in Vienna, October 31, 2015.
Traditionally, we have developers meeting day before PGCon conference, where we meet together and discuss various important questions. I made this shot, so you can't see me there :)

This is a historical picture I made in lobby of the Conrad Dublin hotel. We just got an idea how to make index for our jsonb, which should be faster mongo database. Alexander Korotkov made a prototype, which proved our idea, when we were waiting our dinner. This was happened before our talk on jsonb. Now this is a history ! Users of PostgreSQL 9.4 could enjoy jsonb_path_ops.
Mark Wong and Oleg Bartunov talk in lobby of the School of Information Technology and Engineering (SITE) at the Univeristy of Ottawa during PGCon 2007. A major PostgreSQL developer, Oleg Bartunov presented "Full Text Search in PostgreSQL". PostgreSQL contributer Mark Wong co-presented "Digesting an Open-Source Fair-Use TPC-E Implementation".
Peter Eisentraut, Bruce Momjian, Gavin Sherry, Josh Berkus and Andrew Sullivan -- the guys who made the Summit a reality!
I catch the moment, when Tom was listening Peter van Hardenberg (Heroku). It's very typical for Tom to be very attentive to the speaker.
Tom Lane is the most famous and respectful postgresql hacker. I work with Tom on hacking postgresql more than 10 years. Russian hackers (I, Teodor Sigaev and Alexander Korotkov) presented him russian doll (matryeshka in russian) as a mark of gratitude of his contribution into reviewing our patches. Tom asked us to sign the russian doll and we are very pleased to do this.
Russian Doll tree, also known as RD-Tree, is the data structure, which actively used in our development, such as full-text search, ltree, pg_trgm, hstore and other extensions.
Belgian GR-paths contributed to Openstreetmap rendered by Tilemill (postgresql database import) and served as tile map service by Leaflet as an overlay over the excellent free MapQuest-OSM maps.

Alexander Korotkov, Jeff Davis, Peter van Hardenberg and Will Leinweber at the first snow day in Prague. It was cold and snowing, the road was slippy, but were brave enough and climb to Metronom in Letny park.
Álvaro (ToroDB) visited our office to discuss possible collaboration with our PostgreSQL development team.
Alexander Korotkov gave a talk in European PostgreSQL conference about indexing regular expressions in PostgreSQL.
