'Several problems in Distributed Systems can be seen as the challenge to determine a global state. In the classical " Time, Clocks and the Ordering of Events in a Distributed System " Lamport had laid out the principles and mechanisms to solve such problems, and the Distributed Snapshots algorithm, popularly know as the Chandy-Lamport algorithm, is an application of that work.

It was brought to my attention that the File plugin for Apache Cordova has no documented methods for finding the available disk space on a device. This does not mean that you cannot figure out how much space is available on your users device because you can make use of Apache Cordova’s nifty cordova.exec function. The post Get Available Free Disk Space Using Apache Cordova appeared first on The Polyglot Developer.

How is it possible for us to communicate securely when there’s the possibility of a third party eavesdropping on us? How can we communicate private secrets through public channels? How do such techniques enable us to bank online and carry out other sensitive transactions on the Internet while trusting numerous relays? In this post, I hope to explain public key cryptography, with actual code examples, so that the concepts are a little more concrete.

Back on the topic of possible programming interview questions, you may at some time in your career be asked to reverse words in a string. This is a much simpler problem and may be more likely to appear on a technical phone screening. In it’s simplest form, you would assume all space separated string collections to be words. To clarify, it doesn’t matter if you’re looking at a true word or just some jumbled text separated by a space character.

The Pointer Events specification just became a W3C Recommendation. For those unfamiliar, it’s an intriguing attempt to unify pointer events regardless of the input device in use. The jQuery team threw their weight behind it this morning. …we love Pointer Events because they support all of the common input devices today – mouse, pen/stylus, and fingers – but they’re also designed in such a way that future devices can easily be added, and existing code will automatically support the new device.
