  A Peek Inside the Erlang Compiler

Erlang is a complex system, and I can’t do its inner workings justice in a short article, but I wanted to give some insight into what goes on when a module is compiled and loaded. As with most compilers, the first step is to convert the textual source to an abstract syntax tree, but that’s unremarkable. What is interesting is that the code goes through three major representations, and you can look at each of them. Erlang is unique among functional languages in its casual scop...

Now, in Part III, he talks about how technology will sweep through education. In my last post, I ...

  Format JSON data on Ubuntu

JSON now becomes a very popular data format because of its simplicity and light-weight. Nowadays many RESTful APIs will offer a choice of exchanging JSON data between the server and client. Sometimes the data may not be formatted and it cannot be easily read by human beings. It's frequently desired that the unformatted JSON data should be formatted before read. Today we will show a few ways to format JSON data on Ubuntu. Assume we have a json file test.json with below content. { "title": "Test"...

  How the Internet Is Ruining Everything

The ongoing argument about whether the Internet is a boon or a bust to civilization usually centers on the Web’s abundance. With so much data and so many voices, we each have knowledge formerly hard-won by decades of specialization. With some new fact or temptation perpetually beckoning, we may be the superficial avatars of an A.D.D. culture.David Weinberger, one of the earliest and most perceptive analysts of the Internet, thinks we are looking at the wrong thing. It is not the co...

  Hey kids, just say NO to programming !

Cory Doctorow's latest talk 'The Coming War on General Purpose Computing' really puts things in perspective about life in the 21st century. This got me thinking more about functional programming languages and how they are related to the intentional limitation/crippling of turing machines by industry and government. What if Stallman is right about the intentional efforts to limit freedom of information ? What if it's even worse than we all think it is ? In relation to functional languages ...

  Overlap Detection

How does one detect when two strings overlap? In the case below, the four-letter suffix of string 1 matches the four-letter prefix of string 2. 1: "Fire at Will" 2: "William Riker is number one" Sometimes there are several matches; finding the longest is not always straight forward. 1: "Have some CoCo and CoCo" 2: "CoCo and CoCo is here." 2: "CoCo and CoCo is here." 2: "CoCo and CoCo is here." The naïve solution is to take...

  Short SASS tutorial

If you learned CSS before, you should know that CSS is not a programming language. You can use it to design webpage style, but you cannot use it for programming, i.e, CSS is what designer uses, not what programmer uses. Programmer may think that CSS is very troublesome, it has no variables, no conditional statements, it just allows line-by-line description of HTML elementsLuckily, CSS preprocessor appear which makes CSS programmable. The general idea of CSS preprocessor is using a programming la...

  The "C is Efficient" Language Fallacy

I came across an article yesterday about programming languages, which hit on one of my major peeves, so I can't resist responding. The article is at greythumb.org, and it's called Programmer's rant: what should and should not be added to C/C++. It's a variation on the extremely common belief that C and C++ are the best languages to use when you need code to run fast. They're not. They're good at things that need to get very close to the hardware - not in the efficiency sense, but in the...

  Why do C++ folks make things so complicated?

This morning Miroslav Bajtoš asked “Why do C++ folks make things so complicated?” in response to my article on regular expressions in C++. Other people asked similar questions yesterday. My response has two parts: Why I believe C++ libraries are often complicated.Why I don’t think it has to be that way. Why would someone be using C++ in the first place? Most likely because they need performance or fine-grained control that they cannot get somewhere else. A Ruby programmer...
