  Performance is a Feature


We've always put a heavy emphasis on performance at Stack Overflow and Stack Exchange. Not just because we're performance wonks (guilty!), but because we think speed is a competitive advantage. There's plenty of experimental data proving that the slower your website loads and displays, the less people will use it. [Google found that] the page with 10 results took 0.4 seconds to generate. The page with 30 results took 0.9 seconds. Half a second delay caused a 20% drop in traffic. Half a seco...

  Three things you should never put in your database


As I've said in a few talks, the best way to improve your systems is by first not doing "dumb things". I don't mean you or your development staff is "dumb", it's easy to overlook the implications of these types of decisions and not realize how bad they are for maintainability let alone scaling. As a consultant I see this stuff all of the time and I have yet to ever see it work out well for anyone. Images, files, and binary data Your database supports BLOBs so it must be a good idea to shove ...

  Pair Programming Stereotypes


Over the last couple of years, I’ve done a lot of pair programming. Pair programming inside my team, at customer sites, in coding dojos and in my open source projects. Pair programming is really a great and effective experience when performed by an pair of developers knowing how to pair program. Unfortunately, you cannot just put two developers in front of a single computer and expect them to perform perfectly from the start. Pair programming has to be learned. Both developers need to lear...

  Location matters for your startup


18 months ago I relocated from my home town of Glasgow, to London, just 400 miles away. An important reason for the move was because I had just started working on my new startup, Teamly, and I know that location matters, even when running an internet business. Don’t kid yourself otherwise, your chance of success is seriously improved when you’re in a startup hub.18 months later and moving to London has proved to be a smart move, for all the expected reasons, as well as  the unexpec...

  Simplicity Oriented Programming


After few years on Warsztat (a Polish gamedev site) I’ve noticed an interesting phenomenon. Every now and then there are Compos (programming competitions) organized in two different flavours. Some compos are single-run events that last only few hours, others are long-term (several days/weeks). And as an extra catch, the former are usually restricted to basic APIs (SDL, OpenGL etc) while the latter are free-for-all (all sorts of engines, UDK/Unity allowed). Now, results are somewhat shocking. M...

  30-Minute Exercise to Become a Better Programmer


I believe that motivation is really important. That’s why from time to time I read books about time management (as they motivate me to be focused and continue evolve my TM-system) and books about software craftsmanship. The other day I finished one of this kind of books - “Apprenticeship Patterns: Guidance for the Aspiring Software Craftsman”. This book motivated me to think carefully what I want to invest my time in. Also, it coincided with my 25th birthday and, of course, the new...

  Unix Philosophy


First, let me tell two stories.The first one is one Japan soap factory had a problem that they sometimes shipped empty boxes to the customer without soap inside. So they spend much time and money to invent a X-ray machine to check whether the soap box is empty.The same thing happens in a small factory which doesn't have too much money. The solution of them to solve this problem is they use a desk fan to blow the empty boxes out of the belt and into a bin.The second story is NASA finds that in sp...
