  XML Abuse

It’s everywhere. XML Abuse. From Domain Specific Languages to Data Serialization, XML is the most commonly abused data format I’ve ever encountered. XML is perfectly fine for (because it was designed for this): First of all: XML was designed to be written by humans and read by humans. Nearly all generated XML I’ve seen sucks badly. I think this is because XML cannot efficiently represent common data structures found in programming languages.XML is good...

  JavaScript Is Not A Language

Recently people presented arguments for and against using CoffeeScript. I felt the argument against was pointless and obviously wrong, but I couldn't figure out why, and I thought the counterargument for was kind of toothless and irrelevant. I've figured out the real issue.The real argument for CoffeeScript is that JavaScript is not really a language.Years ago I read something which explained, in my opinion, why Lisp has never achieved the mainstream adoption its passionate advocates belie...

  PHP to output string to client terminal

It is a common task to echo messages to the user using PHP. There are lots of ways where the message can be echoed to the client terminal(browser or console window) through PHP. These includes some well know debug methods like var_dump() and var_export() etc. In this post, we will show you some other methods shared by Laruence, one of the core members of PHP development team. 1. echo First comes with the most common one : echo. $str = "Hello PHP\n"; echo $str; 2. print Then comes another c...

  Java is not the new COBOL

If you Google “Java is the new COBOL” you’ll find a glut of articles proliferating this mantra. I don’t know its origins, however I’m inclined to think it’s mostly repeated (and believed) by the Ruby community. Ruby, from a developer’s perspective is a low-friction language. A developer can just sit down at a text editor and start banging out code without really thinking about such superflous things as types. Java on the other hand, well, you h...

  Python threads: communication and stopping

A very common doubt developers new to Python have is how to use its threads correctly. Specifically, a large amount of questions on StackOverflow show that people struggle most with two aspects: How to stop / kill a threadHow to safely pass data to a thread and back I already have a blog post touching on these issues right here, but I feel it’s too task-specific for sockets, and a more basic and general post would be appropriate. I assume the reader has a basic familiarity with Pytho...

  Why I Use Vim

I've been using MacVIM as my editor of choice for a couple of years now, yet in many ways I still feel like a beginner. Every day I am learning more and more about my editor, but it takes a conscious effort to become proficient with an editor like Vim. Here's why I make that effort. Editors are something that are very personal; they have to fit with your own work flow approach to programming. If you have ever stopped to think about it, the way each person goes about editing text is quite differe...

  How to prevent next HeartBleed bug?

How to ensure the security of open source projects is a concern for many open source users including individual users and companies. But it's not an easy task to ensure the security of open source projects. Because everyone can see the source code, there is much higher possibility that a bug may be found by someone. Once a bug is disclosed, people may exploit it and do evil things, this may cause loss of money either for individuals or companies, some of the bugs may even have big impact to the...

  JSON unmarshal in GoLang

In almost all mainstream programming languages, there is either built-in or third-party library to support parse JSON data because it is so popular for organizing and transferring data among different services. In GoLang, the built in json package also provides functions for marshalling and unmarshalling JSON data. Marshalling GoLang struct to a JSON string is relatively simple, just need to call json.Marshal(), it's a bit complicated to unmarshal an arbitrary JSON string into a GoLang struct ob...

  JavaScript finite state machine

Finite state machine is a very useful design model, it can be used to simulate many events in the world. In short, finite state machine has three features: Number of states is finite At any moment, one object can only be in one state In some condition, it will transfer from one state to another state In JavaScript, finite state machine can be applied in many places. For example, one menu element on a webpage. When the mouse hovers on the menu, the menu will show up, while the mouse moves away...
