  How To Optimize Your Site With HTTP Caching

I’ve been on a web tweaking kick lately: how to speed up your javascript, gzip files with your server, and now how to set up caching. But the reason is simple: site performance is a feature. For web sites, speed may be feature #1. Users hate waiting, we get frustrated by buffering videos and pages that pop together as images slowly load. It’s a jarring (aka bad) user experience. Time invested in site optimization is well worth it, so let’s dive in. What is Caching? ...

  The Programmer Salary Taboo

Salary is an interesting topic. It's certainly one everyone has an opinion on. It's also a uniquely taboo subject among members of the working public. Since I'm about a month away from being done with University and entering the programmer workforce, I've taken to asking my classmates what type of starting salaries they're getting at their first jobs. The first thing I discovered is that not everybody is very comfortable with this question, and many companies are even less so. Microsoft requests...

  Lessons from the Trenches

I believe that making a game is part art and part science, so it's no wonder that managing a game project is also part art and part science. Clearly if it was all science then the industry would get a collective F for not having made any significant progress over the last decade - all one has to do is just glance at the published postmortems to see that the same patterns are repeated over and over.A game has to be fun, engaging, grab users in the first two minutes and also keep their a...

  It takes hard work. Do the hard work.

Something I’ve been thinking about a lot recently is the idea of simply trying harder with everything I choose to spend my time on. It seems like an elusive thing, the idea of optimal focus and maximum effort. However, I think there is something to be gained from stopping for a moment and considering how focused we are when we do our daily activities. I think two things apply here: single-mindedness and massive effort. To truly excel at something, we need to be very focused. We can...

  Never ever touch a programmer

This is a technical license plate block example. We don't know whether it is working or not, however, the idea is very good. When you drive through some of the junctions, the camera captures the license number and convert it into text with OCR, and then insert them into the database. Therefore, this license plate on the car becomes a SQL injection. This picture tells us -- never trust user input.Author : 陈皓 Source : http://coolshell.cn/articles/6639.html#more-6639...
