  Time to think about supporting max/min functions for integers in GoLang

Sometime back we wrote a post explaining why there is no max/min function support for integers in GoLang, one of the reasons is that no overloading is supported and the function name has been used for other numeric types float64. To solve this problem and make max/min function support integer as well, either GoLang should support overloading like in Java or the same set of functions need to be created in a different package other than standard math. These don't look like good options as overload...

  Do IE developers feel guilty?

IE won the browser war before Chrome appeared with the help of anti-competitive practices. But with the appearance of more and more easy-to-use and fast browsers, people start to hate IE and leave IE. It seems IE is not a product of modern age. Do IE developers feel guilty about this? Everything is contextual. The browser that most people hate today is IE6, which, at the time was one of the best browsers on the planet (it didn't win the Browser Wars, Round One, by accident). It was built on "int...

In Google, most of the products are written in C++ and Java. They usually don't choose Python to write their product stack. What's behind the decision to choose one language over the other in Google? Let's get to read some opinions from Robert Love, a Google software engineer. Love said he couldn't imagine writing let alone maintaining a large software stack in Python.

  Use CSS calc to align an element vertically

calc function is a function introduced in CSS3, it can be used to calculate length values. There are a few good features which make it suitable for aligning an element vertically.

One example: .rect{ margin-top:20px; height:50px; background:green; width:calc(100%-20px); } Here the left operand uses percentage while the right one ...

Let's first take a look at one simple Java thread code snippet which is supposed to exit the while loop after the first loop run. public class StopThread { private static boolean stopRequested; public static void main(String[] args) throws InterruptedException { Thread backgroundThread = new Thread(new Runnable() { @Override public void run() { int i = 0; while (!stopRequested) { i++; } } }); backgroundThread.start(); TimeUnit.SECONDS.sleep(1); stopRequested = true; } } But the tr...
