  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. By and large, it is difficult to find students who have any exposure to languages beyond this. 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...

  The Giant Mafia

There is an old Chinese saying "Things of a kind come together. People of a mind fall into the same group.". In the wave of Web 2.0, there are many emerging IT giants coming out the world. And many of them are founded by a group of people who previously worked together at the same company such as PayPal and Facebook. This is called giant mafia. Let's see what people from the big IT giant have done after leaving the original company. The PayPal mafia Peter Thiel, co-founder and CEO of PayPal bef...

  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...

  How to password protect a Winzip file

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. Adding a password will ensure more security and reliability of the transported files. How to add a Password to your Zip Fil...

  /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...

  The Wasteful Legacy of Programming as Language

A few years ago I visited a friend who is a graduate student in linguistics. After some time he asked me if I was aware of the work by Chomsky on formal languages. I told him that yes, Chomsky work was a basis for much of the developments in theoretical computer science. More than that, I was glad to learn that there was something technical that I could share and discuss with other people in linguistics. At the time I found this was just a great coincidence. It was only recently, though, t...

  How can I teach a bright person, with no programming experience, how to program?

I usually prescribe the same sequence for anyone who wants to learn programming. It's very theoretical, but it lays a good foundation. It should take three or four months of fulltime study, but programming isn't something you learn overnight.If you can't get through this sequence, you're not going to be able to program, so you might as well give up now.Code, by Charles Petzold.The C Programming Language, K&RThe Structure and Interpretation of Computer Programs, Abelson and Sussman.My rule is...

  Address of a Java Object

In conventional java programming, you will never need address or location of a java object from memory. When you discuss about this in forums, the first question raised is why do you need to know the address of a java object? Its a valid question. But always, we reserve the right to experiment. Nothing is wrong in exploring uncharted areas.I thought of experimenting using a little known class from sun package. Unsafe is a class that belongs to sun.misc package. For some of you the package might ...
