Getting started with WTL on Visual Studio 2010
Now that you have downloaded the latest WTL release (v8.1 at the time of this writing), you will find out that it doesn’t have any project wizards for Visual Studio 2010. That’s a relatively easily fix. Just go ahead and download the latest build from the repository at AppWiz.tar.gz-view=tar. Extract the .tar file and you will find the JavaScript install scripts for VS 2010: I recommend you to extract the files to the same location were you installed the WTL files. In my ca...
Simple explanation about process and thread
Process and thread are two basic concepts of operating system, but they are a bit abstract which cannot be mastered easily. There is an analogy which explains these concepts very well. 1. The kernel of the computer is CPU, it handles all the computing tasks, it's like a factory and will run all the time. 2. Assume there is power limitation for the factory, it can only supply to one unit once,i.e, when one unit is working, other units must stop and wait. The meaning behind this is that eac...

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...

Most Pressed Keys and Programming Syntaxes
I switch between programming languages quite a bit; I often wondered what happens when having to deal with the different syntaxes, does the syntax allow you to be more expressive or faster at coding in one language or another. I dont really know about that; but what I do know what keys are pressed when writing with different programming languages. This might be something interesting for people who are deciding to select a programming language might look into, here is a post on the...

Penrose Tiling in Obfuscated Python
Here’s a Python script which renders some Penrose tiling. Yes, this is valid Python code: _ =\ """if! 1:"e,V=100 0,(0j-1)**-.2; v,S=.5/ V.real, [(0,0,4 *e,4*e* V)];w=1 -v"def! E(T,A, B,C):P ,Q,R=B*w+ A*v,B*w+C ...
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 ...
