  Go vs C benchmark. Could Go be faster than C?

During last semester I was attending Multiprocessor Architectures course, given at Facultad de Informática where I study my Computer Science degree. As part of the assignments due to pass the course, we had to do several programs written in C to benchmark matrix multiplication by testing different techniques and technologies. First of all we had to do a secuential program in three different versions: A normal one where the result matrix is ordered by rows and the loops range the matrix by ...

  Python Performance Tips, Part 1

To read the Zen of Python, type import this in your Python interpreter. A sharp reader new to Python will notice the word “interpreter”, and realize that Python is another scripting language. “It must be slow!” No question about it: Python program does not run as fast or efficiently as compiled languages. Even Python advocates will tell you performance is the area that Python is not good for. However, YouTube has proven Python is capable of serving 40 million videos...

  Kicking ass together: How to improve coding skills as a group

Over the last year and a half, I have worked with a small group of students and staff to create an excellent online learning community at Mendicant University. Unfortunately, because Mendicant is something that we’re intentionally scaling at a very slow pace, we won’t directly reach as many people as we’d like to any time soon. In this post, I’ve collected some of the things that I think contribute to making Mendicant University a great place to learn. I’d love...

  Prototypes and Object Orientation

David Chisnall takes a look at the two dominant paradigms in object-oriented languages (classes and prototypes) and discusses the strengths and weaknesses of each.Two terms are quite often confused when describing programming languages:class-based and object-oriented:Simula was the first class-based language. It provided classes (actually implemented using closures) as a means of encapsulating abstract data types.Smalltalk was the first object-oriented language. It provided a...

  We’re working our young people too hard

Yesterday, I shared an anecdote involving a school I once attended with a list. This anecdote eventually became the basis for a blog post. Traffic was fairly normal for the first few hours until it found its way onto hackernews.Then it exploded.The comments on both the original blog post and the post on hackernews filled almost immediately with opinionated hackers, teachers and students sharing similar experiences, discussing the problem and figuring out what should be done about it.Repeate...

  The Greatest Developer Fallacy Or The Wisest Words You’ll Ever Hear?

"I will learn it when I need it"! I've heard that phrase a lot over the years; it seems like a highly pragmatic attitude to foster when you're in an industry as fast-paced as software development. On some level it actually IS quite pragmatic, but on another level I am annoyed by the phrase. It has become a mantra for our whole industry which hasn't changed said industry for the better. The problem is this, in the guise of sounding like a wise and practical developer, people use it as an exc...

  How Duff’s Device Works

I like C, but I have to admit that, sometimes, “The Old Man of Programming” can be a bit of a killjoy. This is one of the most exciting eras in computer history, but lately, C’s acting like he doesn’t evenwant to have a good time. While the cool kids like Ruby and Haskell are living it up, C’s over in the corner obsessing over bits and bytes and memory alignment and pointers and the stack and machine architecture and unreachable allocations and multiple indi...

  Ruby WinRM undefined method `split' for nil:NilClass

WinRM service is a service provided by Windows to enable remote access a Windows system. It is similar to what SSH is for *nix. And it is frequently used in applications which want to automate process or accessing remote Windows system and perform actions on them. Ruby also provided the WinRM gem which is an implementation of the WinRM service.  When using WinRM gem, one may often want to use :negotiate as the transport protocol for authentication. This transport will negotiate using d...

  HTML5 and Accessibility

Accessibility for people with disabilities is a legal responsibility in many countries. It's also the right thing to do, and one of the characteristics distinguishing professional developers from the WWWs: WYSIWYG-wielding wannabes. But for many, accessibility has been a somewhat black art, requiring adding extra stuff to your code like alt text, table summaries, ARIA information that can be difficult to test by developers who are not assistive technology users themselves.The arrival of HTML5 ha...
