Selective Combinations

Consider this scenario:

You have a list of strings with which you have generate ordered selective combinations of strings starting with the first string in the list. Let us say the list of strings is abc, def and ghi. I have to generate ordered combinations of the above list restricted to the ones starting with abc.

So that would be as follows:

abc def ghi

abc def

abc ghi



In his talk at the CppCon 2014, Bjarne Stroustrup explained, politely and brilliantly, how to write succint expressive yet intent-ful code.

Partial Classes – Java ???

I am really sorry if I tricked you into believing that Java is offering partial class feature. Unfortunately, Java doesn’t. Maybe never will. But I am going to talk about a workaround also presenting the thought process. Hence the length of the post.

Sporting a new look

I am very particular about composing the content of the posts (and pages) on this blog. By content, I mean whatever goes in the body of a post/page – text, image, HTML, etc. I like to keep the content extremely clean and avoid polluting with HTML like I had to on Blogspot. With such content, it is a terrible pain to migrate blogs or render posts flawless and consistent across browsers. Blogger is notorious for that aspect1.

Lights Preserved

I have a separate blog – Lights Preserved where I get to claim myself a photographer, and where I publish some of my artistic snapshots.

.NET for the next generation

It was about a decade ago when Visual Studio .NET 2002 was launched. Having worked with Visual Studio 6 until then, the new interface was refreshing and powerful along with .NET and the suite of languages, tools and technologies. If you were there, you would have felt times were changing. Beyond the cool and modern interface, Visual Studio .NET 2002 had a lot more to offer  compared to Visual Studio 6 — .NET. It was an exciting time for me back then.

final, const and beyond

What are your thoughts on the following piece of code?

public String someGibberishMethod() {
	int length = someMethodReturningLength();
	int sum = 0;

	for (int index = 0; index < length; ++index) {
	   // some code that updates the sum variable

	SomeClass someClass = new SomeClass(sum);
	int sumValueInsideSomeClass = someClass.getSumValue();
	// use someText, maybe log or something

	String someText = someClass.doSomeOperation(/*some parameters*/);
	// use someText, maybe log or something
	return someText;

JAR Tips: Loading dependencies

If you are writing a typical console based application in Windows, you would end up with an executable (exe). You might also have one or more dependent libraries (DLL). The question is where do we place these DLLs so that they are picked up at runtime by the application; loaded and consumed. Actually it is no brainer, just put them along side the console application executable. Or you could place the DLLs in the System32 directory. Or you could add the directory to the PATH. Well, my point was actually to say that the DLLs can be simply placed alongside the executable and it would be picked up.
