PGConf.eu 2012 - evaluation and summary Posted by Magnus Hagander in PostgreSQL at 16:12
It's been a bit longer than last time, but the time has come for a blog post that sums up the feedback we received for this years pgconf.eu in Prague. Let's start out with the overall impressions:
We've actually managed to improve the over all impression slightly - last year had 51% giving us a rating of 5, and this year we got 57%. Event more important, we've kept the rate of people who are giving a score of 3 or lower at less than 1%. According to the numbers, the programme quality was slightly worse than last year - down to 65% giving it a rating of 5, vs 71% last year. We still have 97% giving 4 or 5 - up from 95% last year (well within the margin of error).
All in all, I think we can safely say "job well done" to all the people who worked on the conference - thanks for all your efforts!Continue reading "PGConf.eu 2012 - evaluation and summary"

PostgreSQL Conference Europe ... Posted by Magnus Hagander in PostgreSQL at 20:11
PostgreSQL Conference Europe 2012 in Prague, The Czech Republic, on October 23-26 is now accepting registrations for conference attendance at http://2012.pgconf.eu/registration/.
The Early Bird special price will be available until September 7th, but that's no reason not to get your registration in early! Should you for some reason want to register for just a part of the conference, single day rates are also available at this time.
We have also announced our training schedule at http://2012.pgconf.eu/training/. Take your chance to attend training on the day before the conference, held by major PostgreSQL community contributors like Bruce Momjian, Simon Riggs and Greg Smith, and relational database veteran Joe Celko. Local PostgreSQL experts Tomas Vondra and Pavel Stehule will also give training in Czech. These trainings have a limited number of seats available, so register early to ensure there is one for you!
And don't forget - the call for papers is still open! If you have already submitted a talk, or are planning to submit one, we suggest you wait to register until you have received a confirmation if the talk was accepted or not. The early bird rate will be available long enough for you to register after you have received this notification - and if your talk is accepted, attendance is of course free!
As usual, if you have any questions, don't hesitate to contact us at firstname.lastname@example.org.

PGConf.EU 2011 - the speakers and ... Posted by Magnus Hagander in PostgreSQL at 16:36
This part of the feedback is almost turning into a repost year from year. But it's a good thing to be reposting if any, so I'm doing it anyway. To start with, just take a look at these graphs:
Those are pretty fantastic ratings. A full 84% rated the content quality as 4 or 5, and only 1% rated it as less than 3. That basically comes down to there being no talks of bad quality. This confirms the feeling that we had when we tried to pick out the talks for this year - the number of great submissions where just huge. We had to reject around half the talks submitted, and there were only a few of those that we rejected because we thought they weren't very good. Most were simply rejected because we didn't have the time and space to accept them all.
The ratings people have given our speakers confirm what we have always thought to be one of the reasons people like the conference - and many other PostgreSQL conferences as well: you get to listen to and talk to the people who really know what they are talking about. Often because they are the very people who wrote the software in question. A whole 96% of all the ratings gave our speakers a score of 4 or 5 for their knowledge of the topic. And nobody scored lower than 3. These truly are the experts you get to meet!
Most of our speakers also scored very high on the Speaker Quality metric. Our top speakers this year were:
This really is the reason why people come to the conference, and keep coming back the next year - our outstanding speakers! Thank you all for showing up this year to give your presentations, and we hope to see you again next year!
That concludes the posts I'm going to make about pgconf.eu feedback this year. Some of you have already asked about next year, and I'm not going to post any information about the feedback we got there - yet. We are reviewing the feedback we received, and are soon going to start looking for a good venue for next year. We have made the mistake before of announcing a location before we had a venue secured, and we're not going to do that again. We are going to announce it as soon as we know, but that will not be until we have actually decided on an exact venue. But we are absolutely planning to do it again next year, and sometime around the same time of the year. Exactly where we don't know yet...

PGConf.EU 2011 - the feedback is in Posted by Magnus Hagander in PostgreSQL at 09:53
Almost exactly a week later than what we said, I have finally closed down the feedback system for PostgreSQL Conference Europe 2011. I think we all needed slightly more time than we expected to recover and catch up properly...
The detailed feedback for each speaker will be sent out during the day today, unless we run into any unforeseen technical issues, and I will try to summarize the conference-wide feedback here. If any particular note that you posted is not referred here, don't worry - we read them all, but there are far too many of them to post here.
Starting with the conference organization itself and it's venue, I'm really happy to see that we have managed to deliver something that the majority of our attendees really like:
Not a single vote less than 4, on a scale of 1-5, for the overall impression. And only one below 4 for the programme. I can only say a huge thanks to the big group of volunteers who ran this conference, and made it what it was. Clearly you did a good job!Continue reading "PGConf.EU 2011 - the feedback is in"

pgconf.eu training announced, call ... Posted by Magnus Hagander in PostgreSQL at 20:45
We are happy to announce that our training schedule is now available at http://2011.pgconf.eu/training/. These trainings are full or half day sessions on the day before the regular conference sessions, and come at an extra cost. The available trainings are:
Seats are limited at these trainings, so we advise you to book as soon as possible. Training is booked as additional options on the standard conference registration form.
Call for papers
Since we are still in vacation period for a lot of people, we have decided to extend the deadline for our call for papers. The new deadline for submitting talks is midnight, Sep 2nd.
We will, however, start approving talks that have already been submitted as soon as possible, and announce them as soon as we have decided. That means that if you want to be sure that we will have time to review your talk, you should submit as soon as possible!
Full call for paper details are available on the site.

The call for papers for PGConf.EU 2011 in Amsterdam will close at the end of this week. Now is the time to get your talk submissions in!
We are interested in all kinds of talks - from deep technical ones, to novice oriented advise and case studies of interesting things done with PostgreSQL. We expect a wide range of different skillsets amongst our visitors, so we want a good spread of the talk topics as well!
Of course, all speakers get free entrance to the conference on all days (training sessions not included).
If you have any questions for us, don't hesitate to contact us.
So, there is nothing to wait for. Head over to the call for papers site and submit your ideas! And please help us spread the word to potential speakers in other communities as well, who may not have seen our posts yet!

PGConf.EU 2011 will be held in ... Posted by Magnus Hagander in PostgreSQL at 08:13
It's time to mark your calendars: PostgreSQL Conference Europe 2011 (formerly known as PGDay.EU) will be held on October 18-21 at the Casa400 Hotel in Amsterdam, The Netherlands.
Like last year, the conference will be held in a hotel venue, combining both the conference rooms and guest rooms, so you don't have to waste any time finding your way around the city. As in previous years, the conference will include full catered coffee breaks and lunches, to make the most of the time. The first day of the conference will be a training day, and the following three days will be regular conference tracks. The conference will accept talks in English, Dutch, German and French, to benefit those attendees who prefer talks in their native language.
We are just starting our search for sponsors - if you are interested in sponsoring the conference, or know someone who is, please take a look at our sponsorship opportunities and don't hesitate to contact us if you have any questions or would like to propose an alternative arrangement.
We will also follow up with a call for papers later, and in due course open for registration and post a conference schedule. For now, mark the dates, and follow the news on our website and on our twitter stream @pgconfeu.

Feedback from PGDay.EU the final ... Posted by Magnus Hagander in PostgreSQL at 11:57
The big change for PGDay.EU this year really was the switch from a university venue (first Monash University in Prato, then ParisTech in Paris) to a hotel venue (The Millennium Hotel in Stuttgart). We believe that much of the rest of the conference was an improvement over previous years - but it was an incremental improvement, whereas the change of venue was rather drastic. Looking at the feedback on this, I think we can conclude that this change was in general a positive one:
We're seeing a total of 75% who rate the venue as a 4 or a 5. Looking at the freetext comments, a large majority of them are very positive, but there are a few ones that stand out:
Amongst the positive ones we find a large number of comments saying that the "integrated venue" or "all inclusive" venue was a great step up.
Closely related to the venue, is the food. Unlike the big north American conferences PGCon and PG-East/West, we have for the past two years tried to provide proper lunches and not just sandwiches/boxed lunches. This obviously costs more money, but we believe it's worth it, and we think our visitors do. Last year we had a catering firm bring us assorted food, mainly cold cuts, at the conference venue, and this year we got proper lunch buffets (including multiple choices for dessert, of course..) at one of the hotel restaurants. I think the ratings speak for themselves - I would encourage those other conferences to look into improving their lunches as well!
A full 82% rated the food as 4 or 5. In the end, the cost for paying for a lunch "on ones own bill" would probably have cost more than half the conference fee - so we think we managed to provide some very good value. In fact, several people rated the food as being the best part of the conference(!)
There was, however, one person who said the food was one of the worst things about the conference - if you recognize that was you, we would very much like to know exactly why (no details were included) - please send me an email or write a comment here!
A few people commented on the large amount of food left over from lunch on at least one of the days - it is up to the hotel to decide what to do about that, but it is our belief that they do something "reasonable" with it - and not just throw it away. We know that the caterers last year delivered all leftovers to a nearby homeless shelter, for example. For next year, we will attempt to again get a specification from the catering/restaurant as to what happens to leftovers.
We feel that the overwhelming majority of our visitors found the changes an improvement, and we will therefor pursue something similar as our primary option for next year. We are always interested in improving further, of course, so if you have any other ideas - let us know! The final question we asked about the venue was where to hold the conference next year. Many were quite ambiguous in their suggestions ("big city in Europe" is in, "Hawaii" is out because we want to stick to Europe). Summarizing what we could gave us the following:
The final part of our evaluation was considering the conference website and registration:
In general these are very good rates. I'm happy to see that more than 50% rate the website overall experience as 4 or 5 - that's a much better rating than it's being given by the people who edit the content on it! Same for registration, with very few people rating it really low. There's clearly some room for improvement though:
In summary, here are some reasons in graphical and textual forms why you should already put attendance to next years PostgreSQL Conference Europe in your budget:
That concludes my summaries of the feedback from this years PGDay.EU conference. If your specific comments haven't been called out here, don't worry - we still read them all and will consider them all for next year!
Finally, thanks again to all who helped make this conference great!
See you again next year!

Feedback from PGDay.EU - the speakers Posted by Magnus Hagander in PostgreSQL at 15:37
The next issue of my "pie-chart-overflow blog posts about PGDay feedback" is about our speakers. The speakers are, if that's not obvious, the reason that people come to the conference. Having good speakers is an absolute requirement if we want to keep up the quality of the conference. Other things like venue and price are certainly important, but nothing compares to the actual content of the conference - which is provided by our speakers.
I'm very happy to say that we seem to have manage to keep the very high numbers for Speaker Quality that we had from last year (differing less than 3% which is well within the margin of error). The same goes for the scores our speakers got on their knowledge of the topic - indicating that we've managed to attract some of the most skilled speakers in the world. Which is not surprising given that in many cases, we the person speaking about a feature is actually the guy who wrote it. What is more surprising is that these same people are rated as very good speaker - which we all know isn't always true about your stereotypical developer.
Just like last year, we're not going to post the complete list of speaker ratings, given that they are easy to read wrong. But here is a list of our top speakers, excluding any that had less than 5 ratings. Any speakers who have fewer than 10 should be considered a very uncertain number, and I've again included the standard deviation to determine the uncertainty. We had a lot more speakers this year, so I have only included those scoring 4 or above this time around. Each speaker has received his own detailed score, of course.
The list based on Speaker Knowledge looks slightly different, but not very much. Given that our speaker knowledge has been rated even higher than speaker quality, I've only included those who scored 4.6 or higher (which is a fantastically high cutoff)
A great big thanks to all our speakers - you did a fantastic job.
We will need to work hard to keep up our recruiting of speakers for next years. If you were considering but decided not to submit a talk for some reason - please let us know why, so we can improve! Or if you have any ideas in general on our processes around this. For example, we had no female speakers at all this year - we know you're out there, and we certainly want you there, so what do we need to change to make this more interesting for you as a potential speaker? The same goes for other groups that we were missing of course: now is the time to let us know so we have the time to change things before next year!
