In 2012, let’s stop talking web design and start talking product design
“My hope for 2012 is that some of the old guard of well-respected web gurus stop talking HTML and CSS and start talking serious development. I love the way many of the old guard write and evangelize, but I’m tired of discussing basically the same stuff we were in 2006.†I wasn’t specifically referring to Jeffrey Zeldman, but he (somewhat arrogantly) assumed I was, and responded with a sarcastic, “And a merry Christmas to you, sir.†...

bash network interface
Some of us may have seen /dev/tcp/<host>/<port> before, is this a special file system implemented in some BSD kernel? Because there is no /dev/tcp in Linux. Actually, this one is implemented in bash. We no need to rely on wget,nc to do network connection. It's very easy to use this interface: bash-4.2$ cat </dev/tcp/time.nist.gov/13 56188 12-09-18 15:34:26 50 0 0 733.5 UTC(NIST) * bash-4.2$ exec 3<>/dev/tcp/www.w3.org/80 bash-4.2$ echo -e "GET / HTTP/1.0\n\n" >&3 b...

How DNS lookup works
When accessing a website, a domain name would be needed normally.

The advantage of this mode is it's easy to implement and the execution environment is relative simple; the disadvantage is that if one task takes long time, the tasks following it must wait in the queue and this will delay other tasks consequently. Th...

On testers and testing
Over the years, I’ve come to hold some strong. opinions on testing, testers and the entire business of quality assurance. Inspired by this post on Facebook’s testing, I wanted to write this down so I can point people to it. Some of this is controversial. In fact, even mentioning some of this in conversation has caused people to flip the bozo bit on me. Most product teams don’t need a separate testing role. And even if they do, the ratio of full time dev:full time te...

I've got an idea for an app
I’ve been an iPhone developer for over three years now. The first app I built was CookieCombo. We sold enough copies to go bowling twice, but still it was completely worth it. We tweeted about it, and got some awesome gigs out of that. Everybody was in need of iPhone developers, and there was a huge shortage. Good times.As more and more people got to know that I’m an iPhone developer, I got to hear the following phrase more often: “Hey, you know, I got a great idea for an app...
