  the Performance Golden Rule

Yesterday I did a workshop at Google Ventures for some of their portfolio companies. I didn’t know how much performance background the audience would have, so I did an overview of everything performance-related starting with my first presentations back in 2007. It was very nostalgic. It has been years since I talked about the best practices from High Performance Web Sites. I reviewed some of those early tips, like Make Fewer HTTP Requests, Add an Expires Header, and Gzip Components. ...

Since I started this blog, I have gotten quite a few emails asking me “What programming languages do you recommend for X?” I often finding myself writing something along the lines ofI would honestly recommend python. Something about me being biased because I know and love it.  Usually say something about the competing technology with a back handed insult.

  Using PHP sessions across subdomains

By default, PHP uses the 'PHPSESSID' cookie to propagate session data across multiple pages, and by default it uses the current top-level domain and subdomain in the cookie declaration. Example: www.domain.com The downside to this is that the session data can't travel with you to other subdomains. So if you started a session on www.domain.com, the session data would become unavailable on forums.domain.com. The solution is to change the domain PHP uses when it sets the 'PHPSESSID' cookie. ...

  The Number One Trait of a Great Developer

Maybe the best programmers aren’t those who spectacularly solve crazy problems, but those who don’t create them, which is much more silent. – Lena HerrmannWhen I look around at other companies hiring Ruby on Rails developers, I see them focusing on three major traits: Super-smart; Large community following; Deep Ruby knowledge. They’re all wrong. While these are great aspects in moderation, they all miss the number one quality of a fantastic developer: Judge...

Unfortunately, the first thing that pops into anyones head when a Zynga game is mentioned is Facebook. Facebook is the platform upon which their success stories like FarmVille were built, but it’s not the reason for their success.Zyngas games work because they are fun.

Below I’ll give a couple general examples of surprising applications and then I’ll give a couple more personal applications I found surprising.Number theory has traditionally been the purest of pure mathematics. People study number theory for the joy of doing so, not to make money. At least that was largely true until the ...
