  Clean Code Versus Great Code

I've had some interesting discussions with other developers about writing code recently. I often have the impression that some developers put too much emphasis on clean code. Don't get me wrong, i strive for clean code as well, and have written about its importance quite a lot in the past couple of years. But when i'm coding, clean code is my secondary goal and it could never take the place of my primary goal: making it work. And preferably, i want to make it work great. A lot of people love t...

  Output a file with HTTP range header in PHP

When downloading a large file, we may encounter some network issues which causes download termination and only part of the file is downloaded. When the network connection resumes next time, we may need to redownload the file again from the beginning. In order to save bandwidth, http provides a Range parameter in its header which can control the file transfer flow. With the range parameter in the header, we can resume the download from where we stop. Here is a piece of PHP code snippet which uses...

  Why Building a Mobile App is Hard

Kent Nguyen has a great article about how building iOS apps takes a lot of work. And, here at Parse, we agree. Making a well-designed app is not a trivial task. Many non-developers hugely underestimate the amount of sweat and tears that goes into a single app. The big component that is overlooked and that Kent stresses is the server component. An app is not an island. Users expect their apps to richly interact with the internet. This means you need to worry about developing code on servers, com...

  JavaScript tips both novice and veteran developers can benefit from

In this post, we will share some less known but powerful JavaScript tips which can benefit both novice and veteran JavaScript developers. 1. Truncate array with array length We all know that object are passed by reference in JavaScript, but we may be bitten by this rule. Please check below example: var arr1 = arr2 = [1, 2, 3]; //Change arr1 arr1 = []; // arr2 will still be [1,2,3] arr1 and arr2 point to the same array [1,2,3] initially, later when arr1 repoints to [], the reference to arr2 is n...

  On Programming Deadlines

There are a lot of differences between programming, and programming professionally. The most notorious of which, is deadlines.DeadlinesWhen you're writing code for yourself, you can spend as much (or as little time) on it as you please--but when you're writing code for other people, you've got only a limited amount of time and resources to get the job done. In my experience, this typically leads to one of two situations:You've got to extend the deadline to finish the job properly.You've got to w...

  How deep should unit test go?

There is a question on Stackoverflow which says "How deep are your unit tests?". It is asked by a guy named John Nolan. The question is not too new, but what catches me is the Best Answer given by Kent Beck, who is the creator of Extreme programming(XP) and Test Driven Development(TDD). Let's look at the question first. The thing I've found about TDD is that its takes time to get your tests set up and being naturally lazy I always want to write as little code as possible. The first thing I seem ...

Comparable and comparator are two similar interfaces used to compare objects in Java. When we want to sort a list of objects such as Employee or User etc, we may need to implement these interfaces to make them comparable as we want. However, there are some differences between comparable and comparator interface.ComparableA comparable object is capable of comparing itself with another object. The class itself must implements the java.lang.Comparable interface in order to be able to compare its in...
