The book is in its final stages. Right now I am putting the finishing touches to the illustrations and going through the editors’ most recent comments and suggestions. Takes a lot more time than expected, though…

Introduction

I don't know about you, but I can't imagine doing my PHP development without an IDE with a debugger anymore.

It autocompletes for me, it lets me step through each line of code, jumping around the project, execute and change the code flow on the fly, and does many other things that make me feel cozy, comfortable, and efficient at PHP development (as opposed to, say, CPP which makes me feel cold and lonely).

There are many PHP IDEs out there and I've tried most of them (including the free PHPEclipse and PDT for Eclipse) but kept coming back to NuSphere's PHPEd every time. The other ones just don't do as good of a job and don't have the array of features PHPEd does. Did you know Dmitri, the author of PHPEd, …

In one week, on December 24th, it will be exactly one year since I was first contacted by Packt Publishing. After reading several posts from this blog they asked me if I’d be interested in writing a MySQL administration cookbook with hands-on recipes for those among us who have to make sure the MySQL servers are kept running and in good shape.

Funny thing, I almost deleted their email, because initially I thought GMail’s spam filter had not caught some sort of bulk or phishing email, because I had never heard of Packt Publishing before and at first only saw an unfamiliar sounding sender’s name. As I was one of very few people in the office on that day I decided to read it anyways. Turned out to be not so spammy after all…

What followed were several weeks of sending mails back and forth, convincing a colleague to co-author and together set up a chapter outline. Finally, around February we started writing actual contents. …

Last week, my colleagues Giuseppe, Kai and myself attended the SAPO Codebits event in Lisbon, Portugal. Codebits is an annual, invite-only hacking event, which went on for three days. The venue they chose this year was the "Cordoaria", a former rope factory located in the Belém district, close to the 25 de Abril Bridge (which is an impressive sight!). I have been told that the Cordoaria is the longest building in Portugal and I have no doubts about that! The building is so long that the crew used bicycles to get from one end to the other. I've taken a number of …

I need help with this. I had a dream… Well, not so much as a dream, maybe a “It’d be cool to…”

I thought it’d be nice to discover new photos on flickr using your favorite photos and the people who also favorited those photos, and the favorite photos of those who also favorited my pictures. Still with me?

It’s actually a quite simple code (about 500 lines, check it on github: discovr), but it’s terribly slow. Some possible reasons:

• Way too much data. I’ve found people with around more than 18000 favorites, and there are photos with more than 2k fans. After limiting to 50 last …

This blog post is a by-product of my preparation work for an upcoming talk titled "Why you should be using a distributed version control system (DVCS) for your project" at SAPO Codebits in Lisbon (December 3-5, 2009). Publishing these thoughts prior to the conference serves two purposes: getting some peer review on my findings and acting as a teaser for the actual talk. So please let me know — did I cover the relevant aspects or did I miss anything? What's your take on DVCS vs. the centralized approach? Why do you prefer one over the other? I'm looking forward to your comments!

Even though there are several distributed alternatives available for some years now (with Bazaar, git and …

Today I’m proud to announce the first public release of our ActiveRecord database connection magic plugin: DbCharmer.

DB Charmer – ActiveRecord Connection Magic Plugin

DbCharmer is a simple yet powerful plugin for ActiveRecord that does a few things:

1. Allows you to easily manage AR models’ connections (switch_connection_to method)
2. Allows you to switch AR models’ default connections to a separate servers/databases
3. Allows you to easily choose where your query should go (on_* methods family)
4. Allows you to automatically send read queries to your slaves while masters would handle all the updates.
5. Adds multiple databases migrations to ActiveRecord

So you're a small startup company, ready to go live with your product, which you intend to distribute under an Open Source License. Congratulations, you made a wise decision! Your developers have been hacking away frantically, getting the code in good shape for the initial launch. Now it's time to look into what else needs to be built and setup, so you're ready to welcome the first members of your new community and to ensure they are coming back!

Keep the following saying in mind, which especially holds true in the Open Source world: "You never get a second chance to make a first impression!". While the most important thing is of course to have a compelling and useful product, this blog post is an attempt to highlight some other aspects about community building and providing the adequate infrastructure. This insight is based on my own experiences and my …
