  Lasagna Code

Anyone who claims to be even remotely versed in computer science knows what “spaghetti code” is. That type of code still sadly exists. But today we also have, for lack of a better term — and sticking to the pasta metaphor — “lasagna code”.Lasagna Code is layer upon layer of abstractions, objects and other meaningless misdirections that result in bloated, hard to maintain code all in the name of “clarity”. It drives me nuts to see how badly some c...

  Run code with multiple files in the same main package in GoLang

To run a GoLang program, there needs to be a main() function defined. In some cases when developing some demo program which has multiple files and just wanna put them in the same main package and this folder is not in GOPATH, how to run the program? Let's say we have following folder structure where the main() function is defined in main.go. If you just run below command, it would fail to start to run the program and gives some error if some struct is defined in other files and being used. PS D...

  Why every programmer should learn Python or Ruby

If you are a student, you probably know C, C++ and Java. A few know VB, or C# / .NET. At some point you’ve probably built some web pages, so you know HTML, CSS and maybe JavaScript.

And this is a shame because there are a number of programming languages out there which will make you a better programmer. In this article, we give some reasons why you must learn Python or Ruby2. Compared to C...

  Command Line Arguments

Our Hello program still isn’t very general. We can’t change the name we say hello to without editing and recompiling the source code. This may be fine for the programmers, but what if the secretaries want their computers to say Hello to them? (I know. This is a little far-fetched but bear with me. I’m making a point.)What we need is a way to change the name at runtime rather than at compile time. (Runtime is when we type java HelloRusty. Compile time is when w...

Winzip files are great ways of sharing documents and images of large sizes over the web or through email, since their reduced size makes it possible for them to be sent and received. Also, it is easier to manage one attachment than multiple. But what if the file contains sensitive information you don’t want snoopers to see? Simply add a password protection in Winzip.

  /dev/null and /dev/tty in Linux

In Linux, there are two special files /dev/null and /dev/tty. /dev/null will drop all the data written to it, i.e, when program writes data to this file, it means the program has completed the data write operation. But in  fact it does nothing, if you just want the status of a command but not the output of a command, this feature will be very useful. See below shell codes:     /> vi test_dev_null.sh        #!/bin/bash    if grep...
