  What's Wrong with the For Loop

Closures in Java are a hot topic of late. A few really smart people are drafting a proposal to add closures to a future version of the language. However, the proposed syntax and the linguistic addition are getting a lot of push back from many Java programmers. Today, Elliotte Rusty Harold posted his doubts about the merits of closures in Java. Specifically, he asks "Why Hate the for Loop?": I don’t know what it is some people have against for loops that they’re so eager to...

  Functional Programming For Object Oriented Programmers

After recently remarking about how I finally "got" functional programming I was asked by one of my millions of twitter followers... ¬_¬ to write up an explanation of a small F# program spoken in terms that fellow O-O programmers would understand. Before I become too entrenched into the functional programming way of thinking, that is, and can't explain it anymore. As a former tutor this is one of the major problems with being able to teach something once you understand it. You've ...

  Paradigms of Iteration in JavaScript

One of the joys of programming is that no matter how simple a problem may seem there are always tons of ways to solve it. It can be good practice to go back and revisit fundamentals by solving simple problems with as many implementations as you can think of. In this post we'll explore approaches to basic iteration in JavaScript. This style of exercise is a good interviewing technique, too, because it's open ended and leads to good discussions. The focus isn't a tricky, wacky problem you're...

  5 Reasons Your Javascript Stinks

Javascript gets a bad rap on the Internet, but there are few languages that are so dynamic, so widespread, and so deeply rooted in our lives as Javascript is. The low barrier of entry leads some people to call it a script kiddie language, others scoff at the concept of a dynamic language while riding their statically typed high horse. You and Javascript just got off on the wrong foot, and now you've made it angry. Here's five reasons why your Javascript code sucks.1. You're not using a namespace...

  Useful Bash Scripts

Many people hack together shell scripts quickly to do simple tasks, but these soon take on a life of their own.

  Why would a developer invest time in your startup’s platform?

The notion of developing a platform is highly addictive for technology founders. It ticks every “this is awesome” box and its drawbacks do not become evident until after you’ve already overcommitted.When you’re sunk deep in your idea, you start seeing the infinite number of directions it might go. It could be used for creativity or education or advertising or television or personal productivity or anything.Possibilities are exciting.You soon realise you can’...

  Unfortunate Python

Python is a wonderful language, but some parts should really have bright WARNING signs all over them. There are features that just can't be used safely and others are that are useful but people tend to use in the wrong ways. This is a rough transcript of the talk I gave at my local Python group on November 15, with some of the audience feed back mixed in. Most of this came from hanging around the Python IRC channel, something I highly recommend. [update 2011-12-19: improved "array" cr...

  Where Have You Installed Your Python Packages?

Preface I am writing this article because I recently noticed in the Python community that there are several frequently asked questions: Why does running the command after installing pip result in a "executable not found" error? Why does importing a module result in a "ModuleNotFound" error? Why can I run my code in PyCharm, but it doesn't work in the command prompt? Rather than just providing solutions, it is better to teach people how to fish. To address these types of issues, you need to und...
