I recently started working on a few Node.js applications. Coming most recently from PHP (and Drupal in particular), I found the transition to Node.js to be surprisingly easy. Pleasurable, in fact. But I had to learn to think differently about a few things.Below I list the five things I think every PHP developer should know about Node.js.1. Node.js Is Built On Chrome's JavaScript EngineGoogle's browser, Chrome, has a notoriously fast JavaScript engine called V8. And this JavaScript engine can be cleanly separated from the web browser. Node.js is built on V8. This is one of the main reasons why ...

I often argue that professionals should share their knowledge online via blogging.The catch is that virtually anything worthwhile in life takes time and effort, and blogging is not an exception to this statement. So before committing your energy to such an endeavor, you may rightfully stop and wonder what’s in it for you. Is blogging really worth it?In this article, I briefly illustrate some of the main benefits that directly derive from running a technical blog.1. Blogging can improve your communication skillsCommunication and writing, much like programming, are skills honed through co...

Being a programmer, you have an invaluable skill that you need to learn to harness. Investors realize this already which is why they’ll spend stacks of cash to have you build them something that’ll someday be profitable. Large corporations realize the value in good developers and sometimes bend over backwards trying to retain their top talent. To be able to program well is a skill that people clearly value but why do programmers tend to place such little value on their own talents?I know amazing developers who have spent the last decade building other people a fortune in IP while...

I recently had a very interesting conversation with a friend who recently launched an online business, and it surprised me how our fears are never what they seem to beIt went something like this:B.: I need your help. I launched my product a few months ago, but I am not getting any sales.Me: Do you have traffic?B.: Not much, about 100 visitors a monthMe: Then you need to get more traffic. You probably need at least 100x that amount in your market to start seeing any sales.B.: And how do I get that many people?Me: It might take a while, but find out people who would love to have your product, or...

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. It doesn’t matter whether you are an individual or a corporation, or what corner of the world you in...

There’s never been a better time to be a developer, says The Kernel’s technical editor. But in exchange for all the resources laid out in front of you, what are you doing to give back? There’s never been a better time to be a developer. Thanks to an unprecedented range of open-source software, learning resources and useful web services at our disposal, we can learn new languages, get help, collaborate with others and, if our ideas win traction, there’s now a multitude of investors waiting in the wings to help us build companies around our pro...

As a developer, you are sitting on a goldmine. Do you even realize it? No, seriously, a @#$% goldmine!Never in modern history has it been so easy to create something from scratch, with little or no capital and a marketing model that is limited only by your imagination.Think about the biggest websites you visit or use on a regular basis: Facebook, Twitter, Flickr, Foursquare, or even Google for that matter -- all of them were created by developers who created something from little more than an idea in their head. Was it easy for them? Heck no. But it could only have been done in today's day and...
