Just a quick note on implemeting “orientation hinting” with a default orientation lock at the start. What it actually means: Say, an activity is defaulted to landscape mode lock, and still allowing the user to change back to portrait only when the user intentionally doing so (rotate the devices to landscape then back to portrait).

They enhance the phone with features, provide users with information, acting as a gaming devices… There’s no doubt apps are so crucial to smartphone and that’s why companies like Apple & Google are so keen on making their AppStore better, development tools richer so that more developer will develop for the platforms, and more users would want to buy apps from the stores.

Unfortunately though, it’s also an editor that have the steepest learning curve, it’s hard to explain, simply refer to the following images. *Image ref from StackExchange Scratching the surface It’s definitely not a beginner editor of choice, given the learning curve.

Git has been gaining popularity the past few years, together with awesome web-interfaces from Github, Bitbucket etc. people are adopting the tools quicker than ever.

It is not until you have ruined the versioned copies – e.g. hard reset, would you wish you could have a recovery command. Oops Say, you issued the following command without much thinking:

Paxos Algorithm was the work by Leslie Lamport. It is the foundation for solving many fundamental problem in distributed system. Famous systems that make use of the algorithm included but not limited to Google Chubby, ZooKeeper. Recently he was awarded the Turing Award 2013 which is a great honour to him & well deserved, this makes a good opportunity for me to go over the Paxos Algorithms again, and explain it a bit here for myself to keep my memory fresh.
