  I am a programmer

Admitting that may be career suicide, or possibly it will cost me dearly because 'software engineers' are raking in the big bucks these days, but the fact of the matter is that I'm a programmer. It's what I do best and it is the job title that I associate with most because it feels as though the biggest chunk of me will always be most likely to blurt that out when people ask me what my job is. That I like to program definitely helps.So instead of choosing some fancy title for what it is that I d...

  Three ways to define class in JavaScript

In object oriented programming, class is the template of object, it defines the properties and methods of a group of objects. Unfortunately, JavaScript doesn't support class, but we can have some workarounds to simulate class.1. Constructor functionThis is the classical approach, it is also the approach mentioned in many text books. It uses the constructor function to simulate class and it uses the keyword this to represent the object internally.function Cat() {　　this.name = "Kelly...

  If PHP Were British

When Rasmus Lerdorf first put PHP together, he - quite sensibly, despite his heritage - chose not to write it in Greenlandic or Danish. Good job too - that would have been rather unpleasant to work with. He opted instead, being in Canada at the time, for the local tongue. No, not French - that bastard dialect of the Queen's English commonly referred to as "US English"1. PHP developers in Britain have been grumpy about this ever since. What was he thinking? And more importantly, how do we ...

  Preparing for the real costs of cloud computing

Computerworld - At a cloud computing conference in New York in June, a number of speakers pointed out that the cloud is moving past the hype stage and is beginning to deliver tangible benefits to organizations. These improvements include increased flexibility and agility. But moving to the cloud can also mean added costs, some of which might be unexpected, according to IT executives whose organizations have implemented cloud services or are considering them. While these types of costs ...

  Linus Torvalds’s Lessons on Software Development Management

If anyone knows the joys and sorrows of managing software development projects, it would be Linus Torvalds, creator of the world's most popular open-source software program: the Linux operating system. For more than 20 years, Torvalds has been directing thousands of developers to improve the open source OS. He and I sat down to talk about effective techniques in running large-scale distributed programming teams – and the things that don’t work, too.Torvalds says there are...

  When will resizing be triggered in Java HashMap?

HashMap is one of the most frequently used collection types in Java, it stores key-value pairs. Ideally it expects to use hash table which expects the data access time complexity to be O(1), however, due to hash conflicts, in reality, it uses linked list or red-black tree to store data which makes the worst case time complexity to be O(logn).  Although collections are using data structures like arrays and linked lists, unlike arrays, they will dynamically resize when there is not enough spa...

  Dart is to JavaScript as C# is to C++

Given the background of Lars Bak, the Google engineer whose V8 JavaScript interpreter upended Firefox's claim on speed, it was reasonable to suspect Google's new Web development language might look a lot like Smalltalk. But that might have taken the Web in a strange and different direction. Today, on the day of a Web developers' conference in Denmark, Google and members of the Chromium open source development team raised the curtain on Dart, the company's bid for a new and somewhat more str...

  Why Software Is Eating The World

This week, Hewlett-Packard (where I am on the board) announced that it is exploring jettisoning its struggling PC business in favor of investing more heavily in software, where it sees better potential for growth. Meanwhile, Google plans to buy up the cellphone handset maker Motorola Mobility. Both moves surprised the tech world. But both moves are also in line with a trend I've observed, one that makes me optimistic about the future growth of the American and world economies, despite the...

  10 habits of 10x developers

Last week, I discovered The Rise of Developeronomics via Brad Feld. As long as I’ve lived, it has always been a great time to be a software developer. The economics keep getting better for us. My favorite quote: The one absolutely solid place to store your capital today — if you know how to do it –  is in software developers’ wallets. If the world survives looming financial apocalypse dangers at all, this is the one investment that will weather the storms. ...
