PHP and mongoDB MongoDB is a scalable, high-performance, open source, document-oriented NoSQL database. It features document-oriented, JSON-based document storage and dynamic schemas providing simplicity, power and flexibility, combined with full indexes similar to what a traditional RDBMS user would expect. MongoDB also provides solid replication & high availability features as well as an auto-sharding system for transparent horizontal scalability. This talk introduces MongoDB for developers who aren't familiar with it with a detailed introduction of how to work with MongoDB from PHP. This talk will cover the basics from installing the PHP driver and connecting to mongod to creating, inserting, querying for, and updating documents. We will also briefly touch on aggregation, geospatial indexes, GridFS and running database commands.

In the last part I will show the remote debugger capabilities of Xdebug, where you can: set breakpoints on functions, methods and file/line compabinations; watch execution details such as stack frames, per-frame information; run PHP code to modify the current state of your script and evaluating error messages. On top of this you will also see how you can use Xdebug's profiler to find bottlenecks in your applications.

Both GNOME, KDE, as well as the Open Moko Linux computing platform use it extensively for everything related to talking to services and hardware. Skype, as well as other applications, provide D-BUS APIs as well. In this presentation I will be presenting a PHP/D-BUS integration to allow PHP to talk to D-BUS aware applications. I will demonstrate controlling Skype from PHP, as well as the implementation of PHP-GTK based applications on the OpenMoko to talk to, and use the different hardware services it offers, such as GSM and GPS. This talk should show a few things that people don't really associate PHP with, and thus provide some insight that PHP's strength is not only on the Web.

In this session I will talk about the first steps of getting to know PHP, its community and developers. Of course times have changed now, and we are in the Web 2.0 era now, but the KISS principle still applies; for application design, for UI design and for server set-ups. I will also take you to the application development side of the KISS principle, with simpler architectures you can more easily make powerful complex applications. Even in the Web >2.0 era.

This session evaluates possible options for the integration of a search engine into your web-site, ranging from simple solutions such as MySQL's full text to using an external engine to power search. This session deals with implementing a search engine in your PHP applications. After introducing some important concepts will this talk will focus on the multitude of different options to implement a search engine into your website. It will cover different implementations, such as MySQL full text, a PHP based search engine (Zend Lucene), a web service build around Zend Lucence (marjory) and an external Java based application (Solr) and interfaces to it. It will cover the weaknesses and strengths related to installation, availability and performance of all the different implementations that are covered, as well as some recommendations as to when to use what kind of implementation.

I will continue with introducing the test-driven development model - as counter model against traditional software development models, followed by a summary of how a development team could be organized to produce better quality code. After a very quick introduction into Unit Testing and the benefits and problems it brings I will conclude my session with a number of case studies of major and smaller software development teams regarding Test-Driven Development and what it did to their code quality.

Mon, 11 Oct 2010 13:18:44 +0000 talk Great talk, debugging is such an important issue and this talk gave a very good overview (and mentioned Xdebug too!) It was slightly better than at PHPNW10 (http://joind.in/talk/view/2057) because feedback from that talk was used. Mon, 11 Oct 2010 13:18:27 +0000 talk Liked the talk. Good to hear about "proper MVC". Slide-writing interruptions by children had some little bad effect on the slides though. Mon, 11 Oct 2010 13:05:19 +0000 talk Great talk, and well delivered!

Mon, 11 Oct 2010 13:08:09 +0000 talk Kristina did a very good job of introducing MongoDB and the talk gave a very clear overview. Tue, 18 May 2010 18:16:14 +0000 talk Good talk, but you should bitch more about ZSL ;-) Sat, 30 Jan 2010 15:15:32 +0000 talk The concepts and content is good, but the executing of the presentation could be done better by rehersing and walking through it before a presentation. Sat, 30 Jan 2010 15:14:57 +0000 talk Good talk, but I am more interested in the map-reduce stuff and phpillow instead of what couchdb is Sat, 30 Jan 2010 15:13:33 +0000 talk Yeah, would be better if it was walkable distance Sat, 30 Jan 2010 15:10:40 +0000 talk Good introduction... closures are cool but confusing :-) Sat, 30 Jan 2010 15:12:45 +0000 talk Slides are as usual on http://derickrethans.nl/talks.php — the URL I had written down next to this joind.in URL...

Sat, 10 Oct 2009 11:16:50 +0000 talk Well done; I liked it! (Not really much else to say :-) ). Mon, 28 Feb 2011 11:27:12 +0000 talk Awesome. I now most certainly will have a look at Varnish when I have the need for it. It was both well presented, and covered a lot of topics. A joke here and there (making fun of the English) was executed well too. Mon, 28 Feb 2011 11:12:37 +0000 talk So much theory! I liked that, but I had not expected it. I was expecting more of a through comparison between the different NoSQL databases. I know that MongoDB and CouchDB are quite different, but I have not the faintest clue on how, and what I should checkout to not fall into pitfalls with either of them. So I would focus a bit less on the theory, and a bit more on comparing the different NoSQL databases in more detail. Mon, 28 Feb 2011 11:11:12 +0000 talk The topic was good, and well covered. It was a bit of a shame the demos didn't quite work, and that showed that preparation was lacking a bit. I was also not too happy with some of the comments such as a "that's what she said" and some comments about somebody's mum; even though that person was heckling a little. Mon, 28 Feb 2011 11:09:14 +0000 talk I liked this talk. It covered so much however that I'll have to check the slides again :-) Mon, 28 Feb 2011 11:07:50 +0000 talk There was good drinkable tea, and the pastries and biscuits were nice!

Mon, 28 Feb 2011 11:03:49 +0000 talk I quite like this conference venue, and the Angel/Islington neighbourhood. Similar to what Rowan said; the screens being low was a bit of a problem. Mon, 28 Feb 2011 11:05:37 +0000 talk Sadly, the wifi was quite useless. I was a bit disappointed as it was great last year! Mon, 28 Feb 2011 11:02:22 +0000 talk I liked this introduction, but it would probably have worked a bit better as a (longer) tutorial. Wed, 03 Nov 2010 00:37:14 +0000 talk Good introduction, especially the inheritance stuff as that I didn't understand. Mon, 01 Nov 2010 18:58:20 +0000 talk Great introduction to AtomPub. A bit of a pity that it was quite a bit too short. Mon, 11 Oct 2010 13:23:05 +0000 talk Good talk, too bad it was (too) early for a Saturday morning :-) Sat, 10 Oct 2009 10:56:56 +0000 talk I don't think we need yet another template system though, but I'm happy to rant^Wdiscuss it. Thu, 08 Oct 2009 10:26:02 +0000 talk (I've already rated it, but have an additional comment as well.)); insert into talk_comments values (I like this talk, with lots of good information. At some point you mentioned that most PHP functions are not UTF-8 "compliant"—that could perhaps do with an example (such as wordwrap issues). Sun, 14 Jun 2009 21:03:24 +0000 talk As one of the PHP developers many of the topics also are found in "our" project.

Sat, 13 Jun 2009 12:44:58 +0000 talk Good talk, but I think the nested intervals was perhaps a bit too complex to explain in such a small time frame. Sun, 14 Jun 2009 20:58:29 +0000 talk I liked it, and I even managed to pick up some things. However, Raymond should probably leave out the parts about hitting people with bats and breaking fingers. Fri, 20 May 2011 09:54:55 +0000 talk A good opening of the day. Fri, 20 May 2011 09:55:26 +0000 talk It was a good introduction to Solr, but I would probably have liked a few more examples (instead of bullet points). It might also be a good idea to focus more on setting up and features than on why to use it. It's important to know when to look at it, but the balance was in my opinion a bit off. Fri, 20 May 2011 09:56:45 +0000 talk I've only attended for a small amount of time, because it was way too loud and noisy. And that made it impossible to actually talk to anybody. I would not have picked a club as venue, most of us would be much happier in a good pub. I think last years venue, although as cramped as this one, was a lot better. Sat, 21 May 2011 09:52:13 +0000 talk I liked this. It was a bit too long though, and sometimes the jokes didn't work. I know however that's it difficult to get everything working the first time giving a keynote, and Helgi did remarkably well. Sat, 21 May 2011 09:57:00 +0000 talk A good (and short and sweet) introduction into XHP. If not for a lot of questions, the talk would have run quite short. I would perhaps suggest to fill that up by showing some more configuration/examples that tells you how to get started with XHP. Sat, 21 May 2011 10:03:08 +0000 talk @Anonymous: I indeed didn't prepare this much; as it came to mind on the morning to get people to put talks up on the schedule. I'm considering turning this into a real talk, but then it has nothing to do with PHP :-) Sat, 21 May 2011 10:08:29 +0000 talk Like! A good tutorial, lots of energy and good content. I wasn't too charmed of the break videos though. Perhaps it would be good to have the audience show their worked out code-examples though. Wed, 25 May 2011 19:06:28 +0000 talk Excellent talk, good content, but could sometimes go a little bit more in-depth. A few pointers though: - Please don't say you're not that interesting, everybody is :-) - In the framework choice slide, try to put some more contrast so that the logos are all nicely visible. - It was a bit short, but that was okay because there were plenty of questions. However, do repeat the question after people have asked it as the audience can most often not hear the original question-asker. - For some of the questions (and answers) that you got, it would probably make sense to put them in the next version of the talk. - I think it would also help to give a few practical examples. Most of what you spoke about is very theoretical, and of course that doesn't always work. (I realize that you don't want to always use the company you work for as example though :) ). - Give some examples of technical dept. Still, excellent talk and looking forwards to the next version. Sun, 18 Sep 2011 08:34:30 +0000 talk Good talk, it flowed well and it covered a nice (large) area of PHP Frameworks. Sun, 18 Sep 2011 08:35:51 +0000 talk I like the talk, but sometimes the timing was off with the "single words on the slide". I think however, that you could do with fewer "one word" slides as it sometimes felt you were reading from the presentation. Sun, 18 Sep 2011 08:37:24 +0000 talk Good introduction into Resist. Could have dealt with questions a bit better by offering to get back at people. Sat, 28 Jan 2012 09:15:01 +0000 talk Good talk, but the slides could use some work. There was IMHO too much extras in the slides such as the namespace stuff. Some diagrams for the precedence would be beneficial too. Sat, 28 Jan 2012 13:33:19 +0000 talk
