Why developers need a Mac
I am by no means an Apple fan. For one thing, I find Windows (and Linux) stable and fast, so you are not going to hear me argue that my computing life was transformed once I made that Switch (with a capital letter). Admittedly that is partly because I am familiar with how to fix and tune Windows and remove foistware, but it is not that hard. For another, I am not an admirer of Apple’s secretive approach, or the fact that most requests for comment from journalists are responded to wi...

Supercolliding a PHP array
Did you know that inserting 2^16 = 65536 specially crafted values into a normal PHP array can take 30 seconds? Normally this would take only 0.01 seconds. This is the code to reproduce it: <?php echo '<pre>'; $size = pow(2, 16); // 16 is just an example, could also be 15 or 17 $startTime = microtime(true); $array = array(); for ($key = 0, $maxKey = ($size - 1) * $size; $key <= $maxKey; $key += $size) { $array[$key] = 0; } $endTime = microtime(true); echo 'Inserting...
5 Exemplary Material Design Frameworks That Are Worth Knowing

Today, you can observe many mobile and web applications are steadily deploying this design approach and overhauling their UI designs. Material design undoubtedly offers a refined and best approach to create a modern UI design. It embraces polished design principles that have been comprehensively described by Google in its ...

"Programmer" is an Overgeneralization
"Beware of bugs in the above code; I have only proved it correct, not tried it." - Donald Knuth Earlier today, I came across a post during a google-fu session that claimed that no one should use the C++ standard library function make_heap, because almost nobody uses it correctly. I immediately started mentally ranting about how utterly ridiculous this claim is, because anyone whose gone to a basic algorithm class would know how to properly use make_heap. Then I started thinking about all the ...

I am a great programmer, but horrible algorithmist
I am a great programmer, but a horrible algorithmist. It is a thought that has been weighing on me heavily recently, and I'd like to gather other developers feelings on the subject as well. I started what can be called my professional development career back in 1999. I was still in middle school, but my father hired me at his software company. My official duty was to make updates to our websites, but I mostly ended up bugging the other developers to help me learn. From there I picked up ...

Scala feels like EJB 2, and other thoughts
At Devoxx last week I used the phrase "Scala feels like EJB 2 to me". What was on my mind?ScalaFor a number of years on this blog I've been mentioning a desire to write a post about Scala. Writing such a post is not easy, because anyone who has been paying attention to anti-Scala blog posts will know that writing one is a sure fire way of getting flamed. The Scala community is not tolerant of dissent.But ultimately, I felt that it was important for me to speak out and express my opinions. As I s...

Guide to Clearing Storage Space on a Macbook
Macbooks are pretty notorious when it comes to what storage space you have available. Those few gigabytes that you have will disappear in no time if you are not careful. The whole issue becomes even more problematic for people who are not that familiar with Macbooks or have switched from another computer. And if you do not pay attention, it will not take too long before you have next to no storage space on the hard drive. Leaving only a few gigabytes of free space will significantly reduce the ...

How can I teach a bright person, with no programming experience, how to program?
I usually prescribe the same sequence for anyone who wants to learn programming. It's very theoretical, but it lays a good foundation. It should take three or four months of fulltime study, but programming isn't something you learn overnight.If you can't get through this sequence, you're not going to be able to program, so you might as well give up now.Code, by Charles Petzold.The C Programming Language, K&RThe Structure and Interpretation of Computer Programs, Abelson and Sussman.My rule is...
