  What is goroutine?

Casual Talk Golang is quite enjoyable to write, aside from the tedious if err != nil checks. One of the fundamental reasons for the joy is goroutine, a core feature of Golang. Understanding goroutines in detail is worthwhile, as they contribute significantly to the pleasure of working with Golang. So, let's talk about goroutines, hoping to provide some insights to the readers. TL;DR: We'll start by talking about assembling a computer, then delve into some concepts of the operating system, such ...

  Understand JavaScript prototype

For an front end programming language like JavaScript, if we want to understand its OOP feature, we need to understand its objects, prototype chain, execution context, closure and this keyword in deep. If you have a good understanding on these concepts, you should be confident that you can handle this language well. The inheritance in JavaScript is not class inheritance like Java, but it adopts another mechanism-- prototype inheritance. The key to prototype inheritance is the prototype chain mec...

  An open letter to those who want to start programming

First off, welcome to the fraternity. There aren’t too many people who want to create stuff and solve problems. You are a hacker. You are one of those who wants to do something interesting. “When you don’t create things, you become defined by your tastes rather than ability." – WhyTheLuckyStiff Take the words below with a pinch of salt. All these come from me – a bag-and-tag programmer. I love to get things working, rather than sit at something and over-o...

  Dieter Rams' 10 principles of good web design

Dieter Rams is one of the most important designers of the 20th century but his famous 10 principles for good design focused on industrial design. Here Lisbon-based designer Nuno Loureiro applies them to web design “My heart belongs to the details. I actually always found them to be more important than the big picture. Nothing works without details. They are everything, the baseline of quality”  â€“ D...

  Introducing LocalDB, an improved SQL Express

Updated 2011-11-28: Added reference to the walkthrough of using LocalDB in Visual Studio 2010 and to the new LocalDB Installer. Updated 2011-11-02: Added reference to .NET Framework 4 support for LocalDB in the Q&A section. Introduction It gives me great pleasure to introduce a new version of SQL Express called SQL Express LocalDB. LocalDB is created specifically for developers. It is very easy to install and requires no management, yet it offers the same T-SQL language, programming surfac...

  Avoiding and exploiting JavaScript's warts

One's sentiment toward JavaScript flips between elegance and disgust without transiting intermediate states. The key to seeing JavaScript as elegant is understanding its warts, and knowing how to avoid, work around or even exploit them. I adopted this avoid/fix/exploit approach after reading Doug Crockford's JavaScript: The Good Parts: Doug has a slightly different and more elaborate take on the bad parts and awful parts, so I'm sharing my perspective on the four issues that ha...

  Eleven Equations True Computer Science Geeks Should (at Least Pretend to) Know

This idea is a complete rip off an article that appeared in Wired a little while ago and it got me thinking what would my list for Computer Science look like?  Plus I thought it might be a fun post and unlike the Wired list this one goes to eleven.  So here they are in no particular order: Binomial Coefficient The Binomial Coefficient equation generates Pascal’s Triangle and gives you the coefficients for the Binomial Theorem these ideas are often attributed to Pa...

  How Computers Boot Up

The previous post described motherboards and the memory map in Intel computers to set the scene for the initial phases of boot. Booting is an involved, hacky, multi-stage affair – fun stuff. Here’s an outline of the process: An outline of the boot sequence Things start rolling when you press the power button on the computer (no! do tell!). Once the motherboard is powered up it initializes its own firmware – the chipset and other tidbits – and tries to ...

  ECMAScript 5 Objects and Properties

ECMAScript 5 is on its way. Rising from the ashes of ECMAScript 4, which got scaled way back and became ECMAScript 3.1, which was then re-named ECMAScript 5 (more details)- comes a new layer of functionality built on top of our lovable ECMAScript 3. Update: I've posted more details on ECMAScript 5 Strict Mode, JSON, and More. There are a few new APIs included in the specification but the most interesting functionality comes into play in the Object/Property code. This new code gives you th...

  Python Performance Tips, Part 1

To read the Zen of Python, type import this in your Python interpreter. A sharp reader new to Python will notice the word “interpreter”, and realize that Python is another scripting language. “It must be slow!” No question about it: Python program does not run as fast or efficiently as compiled languages. Even Python advocates will tell you performance is the area that Python is not good for. However, YouTube has proven Python is capable of serving 40 million videos...
