  A simple tutorial on Linux nohup command

In our daily work, there might be need to run some important program for hours or even days without being abruptly terminated. In such case, we may want to run the program with command nohup. nohup is the abbreviation of no hangup, i.e, don't hang up or terminate the process. This command will tell the process to ignore the system HUP signal. The HUP signal will be emitted when the terminal is exited or disconnected. Normally process will abort its execution when receiving this signal.  Bas...

  Importance of Side Projects

Side projects are important for a few reasons. Programming is a creative process. Side projects allow programming without deadlines or restraints. Side projects allow programming in an exploratory way. Explore new technologies Every day there are more and more bleeding edge technologies coming out. A side project is a great place to try them out. There’s no reason to worry about bugs or performance issues because it’s just a side project. You’re not depending on the ...

  JavaScript: It's a Language, Not a Community

There's nothing like jsconf for bringing out the meta! Since the conference ended two blog posts have created a lot of buzz, at least within my own twitter bubble. First, Rebecca Murphey's JavaScript: It's a Language, Not a Religion. I take Rebecca's post as a cautionary tale about the dangers of hero-worship and the tendency to assume that the people we respect in one sphere share our views in other spheres. I bring it up here not because I want to discuss the content of her post but b...

  Want to write some code? Get away from your computer!

I’ve recently realised something. The best place to write code isn’t in front of your computer, with your compiler, IDE and tools. The best place to write code is far, far away from any of these tools – somewhere where you can think properly. For a language with which you are fairly familiar, the mechanics of translating the program in your mind to a program that the compiler can compile (or the interpreter can interpret) is fairly easy – it’s coming ...

  Programming Language Readability

Lets compare some Python to Haskell for solving the same problem.  The problem we’ll pick is Trie data-structure for auto-completions.  We are interested not so much in the nitty gritty of the algorithm, but in the language style itself.  Auto-complete has been in the programming news a lot recently; both a Python and a Haskell solver have turned up. (I suspect this post got flagged on Hacker News :(  It never got on the front-page despite the rapid upvoting on a n...

  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 ...

  Build your own internet search engine - Part 2

After having started to build my own internet search engine as described in a previous blog post, I now have read some papers and books about web search engine architecture and information retrieval to complete my hobby project. Here is a list of papers and books that I highly recommend to anybody who is interested in this topic: 1. Google: data structures and algorithms by Petteri Huuhka 2. The Anatomy of a Large-Scale Hypertextual Web Search Engine by the Google founde...
