Do we need other languages other than C and C++?
There were hundreds of or thousands of programming languages created since the invention of computer. All these languages have the same target which is to make the computer do what we want it do. So we may find that many languages have the same functions, i.e, one task can be completed by one language can be completed by another language as well. Now we may wonder why we need so many different languages. Can we just have C or C++ since they provide the best performance we need. The answer obviou...

SameSite attribute in cookie
Starting from Chrome 51, a new attribute SameSite has been introduced for browser cookie. This attribute is to prevent CSRF attack. Cookie is normally used to store data exchanged between client and server. It frequently stores user login information. If a malicious website can forge a HTTP request with the valid third party website cookie, it may be called a CSRF attack. For example, if a user logins to a bank website your-bank.com, the bank server responds a cookie: Set-Cookie:id=a3fWa; L...

Create Packed Indexes with MySQL
I am pretty much sure that you are aware of indexes which we are creating on database fields. Indexes are very useful to make your query search faster and improve the site performance. But the fact is that Indexes which we are creating on database tables also require some additional space on your hard disk and if you have not properly created these indexes than some t...

What programming languages should I learn?
Since I started this blog, I have gotten quite a few emails asking me “What programming languages do you recommend for X?†I often finding myself writing something along the lines ofI would honestly recommend python. Something about me being biased because I know and love it. Usually say something about the competing technology with a back handed insult. Also if they are starting out I would recommend a language that enforces better OO (Object Orientated) practic...

Great code is written twice (or more)
The last couple of years more and more people have been moving towards Agile development. These techniques aren’t new, most we’re devised in the 80s or 90s. But finally these days programmers and (more importantly) business consultants, architects and clients have learned to love and embrace Agile development.Evolving requirementsIt has now become common knowledge that you can’t write down all the requirements before you start the project. These requirements h...

A possible way to recover deleted files on Linux
Last week I was generating a MD5 sum for an virtual machine image on one OpenNebula server: # ls -l test.img -rw-r--r-- 1 root root 10486808576 Oct 12 02:21 test.img # md5sum test.img At the same time I was clearing the files on the server on another terminal and deleted the above image file mistakenly with : # rm test.img Since this image file is 10GB, it took some time to remove this file from the server, so I used the Ctrl+Z command to suspend the remove command. [1]+ Stopped ...
Why developers need a Mac
I am by no means an Apple fan. For one thing, I find Windows (and Linux) stable and fast, so you are not going to hear me argue that my computing life was transformed once I made that Switch (with a capital letter). Admittedly that is partly because I am familiar with how to fix and tune Windows and remove foistware, but it is not that hard. For another, I am not an admirer of Apple’s secretive approach, or the fact that most requests for comment from journalists are responded to wi...

Android Tutorial: Creating and Using an SD Card in the Emulator
In a previous post, I mentioned how user-friendly Android is for developers. There’s extensive documentation and information on the architecture, the different components and best practices. However, the documentation has a few blind spots. Many of the tools have little documentation and no usage examples. The information is there, it’s just hidden behind a few layers of Android theory.So I’m going to try and document a few of the basic things that you’ll probabl...
Don't Overload #nil?
There’s a popular post on Hacker News about writing confident code by, among other things, overloading Object#nil? and returning “null objects†instead of nil itself.DO NOT DO THIS.In Ruby, all objects (except nil itself) coerce to the boolean value true. Your object will be nil and true at the same time. Bad things will happen. Your coworkers will cry. Sad people from around the world will ask bewildering questions on your mailing list.Here’s what happen...
