  Why Every Professional Should Consider Blogging

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 impr...

  JavaScript is now a necessity

I've long looked at JavaScript as a second-class citizen in the programming world. Early on, it was the source of numerous security problems; it was a nice bit of glue to patch together HTML applications with a bit of styling, but nobody would use it for serious code; and so forth. Java, Ruby, Python, they were the languages for doing real work. But my attitude toward JavaScript has changed completely in the past few years. JavaScript has "grown up." I'm sure there are many JavaScript dev...

  It’s Not China; It’s Efficiency That Is Killing Our Jobs

The majority of wealth is now concentrated at the top of the social ladder. This is particularly true in the US, and the gap is widening every year. This, I believe, is because of efficiency, not China. Today the best ideas can efficiently and quickly propagate worldwide, and everyone can efficiently find them and buy them. This makes the owners of these ideas filthy rich, and those ideas that are not the best, can hardly survive. It’s not just transfer of information that is fast; wealth...

  The Mature Programmer

1. The Mature Programmer The mature programmer manages their own time and productivity well. The MP knows that maintenance is as much work as the initial writing and code always takes longer than you think. The MP knows that any changes to code can introduce bugs, no matter how seemingly trivial. The MP knows that premature optimization is foolish and dangerous. The MP knows that sexy coding like writing big complex systems from scratch is rarely the best way to go. The MP does not get...

  How big are PHP arrays (and values) really? (Hint: BIG!)

Upfront I want to thank Johannes and Tyrael for their help in finding some of the more hidden memory usage. In this post I want to investigate the memory usage of PHP arrays (and values in general) using the following script as an example, which creates 100000 unique integer array elements and measures the resulting memory usage: <?php $startMemory = memory_get_usage(); $array = range(1, 100000); echo memory_get_usage() - $startMemory, ' bytes'; How much would you expect it to ...

  The Basics of jQuery

So, a while back I had an internal presentation at work about this topic. A few good friends in the community took a look at my slides, and they thought it would make a nice blog post because “there can’t be too many good posts about jQuery introduction and best-practices.” Whether this post is going to be good or not, is up to you but I’ll try to outline what jQuery is, and how you can start working with it. For most of you, this will just be a re-cap and probably...

  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 ...

  What the Heck are Algebraic Data Types? ( for Programmers )

This post is meant to be a gentle introduction to Algebraic Data Types. Some of you may be asking why you should learn Algebraic Data Types and how will they change your world?  I am not going to answer that, but suffice it to say that Algebraic Data Types are the underpinning of the type systems to the ML derived languages, Haskell and OCaml included, and their construction and properties allow for the power (and inference) that accompanies these type systems.  They are cropping...

  Sass Style Guide: A Sass Tutorial on How to Write Better CSS Code

Writing consistent and readable CSS that will scale well is a challenging process. Especially when the style sheets are getting larger, more complex, and harder to maintain. One of the tools available to developers to write better CSS are preprocessors. A preprocessor is a program that takes one type of data and converts it to another type of data, and in our case CSS preprocessors are preprocessing languages which are compiled to CSS. There are many CSS preprocessors that front-end develop...

  Don't write on the whiteboard

I recently interviewed at a major technology company. I won't mention the name because, honestly, I can't remember whether I signed an NDA, much less how strong it was.I did well. Mostly because of luck. I normally step over myself when I interview. I guess I've improved over the years. Here are a few tips to ace your own interview.1. Don't write on the whiteboardWhen I interviewed at Palantir around 5 years ago, I had a lot of trouble with this. Yes, I knew next to nothing about compu...
