Concurrency vs Parallelism
Concurrency and parallelism are two related concepts which deal with executing tasks "simultaneously". From Sun's Multithreaded Programming Guide: Concurrency: A condition that exists when at least two threads are making progress. A more generalized form of parallelism that can include time-slicing as a form of virtual parallelism. Parallelism: A condition that arises when at least two threads are executing simultaneously. These two definitions are too formal to be understood easily. On t...

When to use STDERR instead of STDOUT
Every process is initialized with three open file descriptors, stdin, stdout, and stderr. stdin is an abstraction for accepting input (from the keyboard or from pipes) and stdout is an abstraction for giving output (to a file, to a pipe, to a console). That's a very simplified explanation but true nonetheless. Those three file descriptors are collectively called 'The Standard Streams'. Where does stderr come from? It's fairly straightforward to understand why stdin and stdout exist, however ...

Guide to Clearing Storage Space on a Macbook
Macbooks are pretty notorious when it comes to what storage space you have available. Those few gigabytes that you have will disappear in no time if you are not careful. The whole issue becomes even more problematic for people who are not that familiar with Macbooks or have switched from another computer. And if you do not pay attention, it will not take too long before you have next to no storage space on the hard drive. Leaving only a few gigabytes of free space will significantly reduce the ...

Is The Cloud Finally Catching Up With Mighty Oracle?
Oracle for years has seemed impervious to cloud computing. First Larry Ellison dismissed it. Then he sort of touted it, his version at least. But all along, Oracle was growing nicely. The industry chatter didn’t seem to matter. Big companies buy big software systems. Something changed this winter. Oracle’s software license sales limped up just 2% in December, and the company blamed customer budget cuts and fears over the European debt crisis. Sales to Europe, Africa and...

Behavior of defer function in named return function
In Go, there is a special concept of named return value in function where a returned value can have name. For example, below is a named function in Go. func returnNamed() (i int) { i = 1 return } When the function returns, the return value i will have a value of 1. Also, Go has a concept of defer which will execute a function just before the calling function exits. This is similar to what finally block does in other languages such as Java. For example, a defer function can be func deferF...

My secret Hobby: Applying for jobs
I have a probably unusual habit: I'm applying for jobs as programmer at least once a year. It 's not that I don't have a job, or that I don't like what I do, but since I am self employed and running my own company I have the feeling that I am coming out of touch of what the current job market is like, and so I started to apply for jobs at different companies once in a while. Just to keep in mind how this is like and for the fun of it.I think this is also a good training should I need to be emplo...
The ugliest C feature:
<tgmath.h> is a header provided by the standard C library, introduced in C99 to allow easier porting of Fortran numerical software to C. Fortran, unlike C, provides “intrinsic functionsâ€, which are a part of the language and behave more like operators. While ordinary (“externalâ€) functions behave similarly to C functions with respect to types (the types of arguments and parameters must match and the restult type is fixed), intrinsic functions accept arguments of...

Open Letter to sites with annoying interfaces
Remember those childhood games where you are given two nearly identical images and your objective was to find some number of subtle differences? Well, I shouldn't have to play that game when I'm using your damn website. I show here two examples of a common practice that is plaguing the modern web. First, a clipping from a project page on github.com. And now the second image: See the difference? My question is this: why? That edit button is the only component of...
