  Prototypes and Inheritance in JavaScript

Forget everything you know about object-oriented programming. Instead, I want you to think about race cars. Yes – race cars. Recently I was watching the 24 Hours of Le Mans –a popular racing event in France. The fastest cars in the race are the Le Mans Prototypes. Although these cars are built by car manufacturers like Audi and Peugeot, they are not cars you’ll see on the streets and highways of your home town. They are built exclusively for high-speed endurance ra...

  5 Great Hacks to Learn Before Launching a Startup

Maybe months or years have gone planning for a startup and finally you are ready to enter into the world of small business.  Excited enough to hit the “Launch” button. As the bulk of your business is good, so the rest of it must be the same. You think like that, right? But hey, you are wrong there. You may be selling the next big thing, but it does not matter until you have frozen your brand name in the niche market and gained a decent amount of credibility. But you can do that...

  Advanced event registration models

On this page I explain the two advanced event registration models: W3C’s and Microsoft’s. Since neither is cross–browser supported, their use is, for the moment, deprecated. W3C and Microsoft have both developed their own event registration model to replace Netscape’s traditional model. Though I’m not impressed by the Microsoft model, W3C’s is very good, except for one crucial vagueness. Unfortunately few browsers support it at the moment. W3C W3Câ...

  Ruby WinRM undefined method `split' for nil:NilClass

WinRM service is a service provided by Windows to enable remote access a Windows system. It is similar to what SSH is for *nix. And it is frequently used in applications which want to automate process or accessing remote Windows system and perform actions on them. Ruby also provided the WinRM gem which is an implementation of the WinRM service.  When using WinRM gem, one may often want to use :negotiate as the transport protocol for authentication. This transport will negotiate using d...

  Investment Banking in China — What I’ve Learned & Unlearned

Anyone seeking to succeed in investment banking in China should live by one rule alone: it’s not who you know, but how well you know them. In China, more than any other country where I’ve worked, the professional is also the personal. Comradeship, if not friendship, is always a necessary precondition to doing business together. If you haven’t shared a meal – and more importantly, shared a few hundred laughs – you will never share a business deal. Competence, ex...

  Create namespace in JavaScript

A namespace (sometimes also called a name scope) is an abstract container or environment created to hold a logical grouping of unique identifiers or symbols (i.e., names). An identifier defined in a namespace is associated only with that namespace. The same identifier can be independently defined in multiple namespaces. That is, the meaning associated with an identifier defined in one namespace may or may not have the same meaning as the same identifier defined in another namespace. Languag...

  How the Go language improves expressiveness without sacrificing runtime performance

This week there was a discussion on the golang-nuts mailing list about an idiomatic way to update a slice of structs. For example, consider this struct representing a set of counters. type E struct { A, B, C, D int } var e = make([]E, 1000) Updating these counters may take the form for i := range e { e[i].A += 1 e[i].B += 2 e[i].C += 3 e[i].D += 4 } Which is good idiomatic Go code. It's pretty fast too BenchmarkManual 500000 ...

  How I Program Stuff

I love programming. I can truly say that of all the things I enjoy, I enjoy programming the most. There's nothing quite like the feeling you get when you create something. Writing code is a lot like building your own little universe. When you build stuff, you're in complete control, and, no matter how hard you fight it, your code directly reflects yourself. If you write sloppy code, I can almost guarantee you'll be a sloppy person. If you haphazardly throw code around with any ca...
