A Small fix for “Waiting for Header” in Ubuntu

03. Jul, 2010 Categories: Server and Hosting by Devyn 0 Comments |

As I’m a Mac, Parallels and Ubuntu user, I have a parallel partition with Ubuntu inside. In parallels, we can specify “Share” or “Bridged” Networking. If you choose “Bridged”, you IP will be appear like a dedicated computer so other users inside your network can access with different IP. However, the problem is when you upgrade or update sources in ubuntu, you’ll get “Waiting for header” which will make you prevent from accessing to sources. That problem can be solved if you switch your networking setting from “Bridged” to “Share” in Parallel.

SQLstream

01. Jun, 2010 Categories: General Log by Devyn 0 Comments |

SQLstream kind of technique that enhances traditional query to support real-time very dynamic data such as chat logs from Database.

In a traditional RDBMS, all data must be stored first, and then queried. RDBMS queries are reactive and finite – in the example query above, a traditional database would return all of the New York orders currently stored and then terminate. A RAM query is a standing query – it executes continuously, processing data before it is stored in an RDBMS, publishing analysis and results immediately. Read More for Details

Failure of RPS Game Project

23. May, 2010 Categories: General Log by Devyn 0 Comments |

RPS Game

Let me introduce my game first. What is RPS? RPS stands for Rock-Paper-Scissors. Yes RPS game but with social networking concept. In short, two players has 16 pieces including 4 rocks, 4 papers, 4 scissors, 3 bombs and 1 flag. Whoever got opponent’s flag will be the winner. During game play, rock beats scissors, scissors beats paper and paper beats rock. However, bomb will kill any item it encounters. That’s the brief of how RPS Game is evolved. In future dev, social activity will be included but I’m not going to cover it right now. So let’s forward to my title.

The project I’m expecting to be one of the most successful games in Facebook is started and developed. But after continuous development in 15 days, I found out it was a failure. Why?
