  Games don’t need to be social

Social games have been a big trend in recent years. Zynga struck it big and now everyone else is trying to emulate them. 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. The social connectivity is merely a mechanism to share your enjoyment of the game with other...

  Why Data Structures Matter

Our experience on Day 0 of JPR11 yielded a nice example of the need to choose an appropriate implementation of an abstract concept. As I mentioned in the previous post, we experimented with Michael Barker’s Scala implementation of Guy Steele’s parallelizable word-splitting algorithm (slides 51-67). Here’s the core of the issue. Given a type-compatible associative operator and sequence of values, we can fold the operator over the sequence to obtain a single accumulated v...

  Full disk encryption is too good, says US intelligence agency

You might be shocked to learn this, but when a quivering-lipped Chloe from 24 cracks the encryption on a terrorist’s hard drive in 30 seconds, the TV show is faking it. “So what? It’s just a TV show.” Well, yes, but it turns out that real federal intelligence agencies, like the FBI, CIA, and NSA, also have a problem cracking encrypted hard disks — and according to a new research paper, this is a serious risk to national security.The study...

In Web 2.0 era, more and more web applications are using AJAX to replace the traditional HTML form element to perform user login. This usually provides a better user experience than form submission. But it also brings a side effect to the end users. That is the browser will not prompt the user whether s/he wants to save the password so that s/he no needs to enter the username/password again when visiting the same site next time. Below is the code snippet which does the AJAX login.  <scri...

  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...
