  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...

  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...

  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...

  Obviously Correct


What do automatic memory management, static types and purity have in common? They are methods which take advantage of the fact that we can make programs obviously correct (for some partial definition of correctness) upon visual inspection. Code using automatic memory management is obviously correct for a class of memory bugs. Code using static types is obviously correct for a class of type bugs. Code using purity (no mutable references or side effects) isobviously c...

  A Solution to CPU-intensive Tasks in IO Loops


Back in October 2011, Ted Dziuba infamously said that Node.js is Cancer.  A provocative title to a provocative article.  The only thing it didn’t really provoke in the commentary was much thought ;)  Zing. My interpretation of the article is that Ted holds up the classic blocking-IO process-per-request (or  thread per request; same difference) model as superior.  Yet we all remember where the blocking-IO forking model got Apache in the early days.  So I...

  Why I Still Use Emacs


At school, I’m known as the Emacs guy; when people have questions about configuring Emacs or making it work a certain way, they often come and ask me. Sometimes, some people ask me why use Emacs at all? Isn’t it a really old editor and aren’t Eclipse or Visual Studio much better? I mean, they don’t have weird key bindings and have intellisense, that’s surely better for a programmer, right? I will attempt in this post to explain some of the reasons why I still cling to Emacs. Believe me...

  Guide to use Compass


Sass is one kind of CSS Preprocessor, it can make CSS development simple and maintainable. But to show its real power we may need to have Compass. This article is to introduce Compass. Once you learn Compass, your CSS development efficiency will be largely improved. Here we assume you have mastered the major uses of CSS, if you know Sass, then it's better. It's still ok if you don't know Sass. 1. What is Compass? In simple, Compass it the toolkit of Sass. Sass itself is only a compiler, Compass...

  Should we use Abstract class or Interface?


When we write programs, we may often get into a situation where we don't know whether we should use Abstract class or Interface when we want to define an abstract object. These two are very similar and they are interchangeable. On Stackoverflow, this question is asked many times, it's related to many programming languages. Also in the official documentation of PHP regarding the Abstract class and Interface, people are arguing about this. To understand this question, we need to understand their d...

  My life as a freelancer


In the summer of 2006 a work buddy, George, has told me that I could make some extra money programming on a site named Rent A Coder. I’ve signed up the same day. After losing some time on a project that never started I lost my interest in “coding for money”. I almost forgot about RAC.Fast-forward two years, I was a PhD student at a small North American University with a student visa and … nothing else in my pockets. For a few months I was able to make a living from a scholarship unt...
