Are older people better programmers?
Peter Knego states something interesting: “It's official: developers get better with age. And scarcer.â€. He uses reputation and other metrics from StackOverflow to corroborate his point. His summary is: Number of coders drops significantly with age. Top developer numbers, at age 27, drop by half every 6-7 years.Developers in their 40s answer roughly twice as much and ask half the questions compared to colleagues in their 20s. It seems younger generation learns and older generatio...

Load and execute JavaScript
When we load and execute JavaScript in a webpage, there are many points we need to care about because of its design and feature. There are two features about JavaScript execution in a browser: 1). The JavaScript codes will be executed immediately once loaded;2). When JavaScript codes are being executed, they will block the following contents (including page rendering and other resources downloading). So if there are multiple js files to be loaded, these codes will be executed sequentially. Since...

UIWebView Secrets - Part1 - Memory Leaks on Xmlhttprequest
My first blog post on iphone subject reveal a big memory bug when using UIWebView component. This is the (only one) component to display some HTML content in an iphone interface.

GET, POST, and safely surfacing more of the web
As the web evolves, Google’s crawling and indexing capabilities also need to progress. Weimproved our indexing of Flash, built a more robust infrastructure called Caffeine, and we even started crawling forms where it makes sense. Now, especially with the growing popularity of JavaScript and, with it, AJAX, we’re finding more web pages requiring POST requests -- either for the entire content of the page or because the pages are missing information and/or look completely br...

Nimbula 'cloud operating system' spans data centers
Nimbula – the build-your-own-cloud outfit founded by Amazon's former vice president of engineering – has announced a new release of its Director platform, saying it will allow businesses to run a unified "infrastructure cloud" across geographically separate data centers.

To create an iframe dynamically, we would normally use JavaScript and with below piece of cod: let iframe = document.createElement("ifrasme"); iframe.innerHTML = "this is some text"; document...
CSS DIV position analysis
When using CSS to set the position of DIV, we may often get confused with the 4 position properties : static, relative, absolute and fixed. If we don't understand them correctly, we may often get unexpected result. Here we make some analysis to them.The definitions of these 4 properties:static : The default position property. It has no position actually. The element will appear where it should be (top, bottom, left, right or z-index has no use here)relative : This one will position relati...
Understanding the "this" keyword in JavaScript
Many people get tripped up by the this keyword in JavaScript. I think the confusion comes from people reasonably expecting this to work like “this†does in Java or the way people use “self†in Python. Although this is sometimes used to similar effect, it’s nothing like “this†in Java or other languages. And while it’s a little harder to understand, its behavior isn’t magic. In fact, this follows a relatively small set of simple rules. This...
