“Enumerating Enumerable” Will Return Soon!

by Joey deVilla on September 17, 2008

Enumerating Enumerable

This is just a quick note to let you know that Enumerating Enumerable, the series of articles in which I try to one-up Ruby-doc.org’s documentation of Ruby’s Enumerable module, will return very soon. I’ve been busy, but I am working on the next installment, which covers the inject (a.k.a. reduce) method.

In the meantime, you can go check out the 18 previous installments, listed below, as well as my paper-assisted demonstration of what inject/reduce/fold means.

  1. all?
  2. any?
  3. collect / map
  4. count
  5. cycle
  6. detect / find
  7. drop
  8. drop_while
  9. each_cons
  10. each_slice
  11. each_with_index
  12. entries / to_a
  13. find_all / select
  14. find_index
  15. first
  16. grep
  17. group_by
  18. include?

Zero Punctuation on “Spore”: NOOOOOOOOOOOOOOOOOOOO

by Joey deVilla on September 17, 2008

Oh, how I enjoy Ben “Yahtzee” Croshaw’s game reviews in his video series Zero Punctuation. In this installment, he covers (and savages) Will Wright’s long-awaited game, Spore. Thankfully, he skips complaining about the DRM, which I heard plenty about already. After hearing his review, DRM sounds like the least of the game’s problems…

The Return of Ruby on Rails Project Night

by Joey deVilla on September 17, 2008

Rails to Victory

After “a much-needed summer hiatus” (which you can read as “the complete implosion of Toronto’s worst-run software development shop, which used to host the event”) Ruby on Rails Project Night makes its comeback this Friday, September 19th at its new home at the Rich Media Institute in Kensington Market.

Event organizer Corina Newby promises that it won’t normally be on Fridays, which should the minds of your significant others, party-going friends or World of Warcraft clans at ease. The event is being held on a Friday this time to accommodate the schedule of special guest James “Smalltalk Tidbits, Industry Rants” Robertson, who’ll be there to give us a presentation of the Smalltalk-based web application framework Seaside and the Seaside-based Smalltalk development environment WebVelocity.

Also scheduled is local Ruby on Rails developer Paul Doerwald, who’ll be doing a presentation on insights he gained from working with ActiveRecord validation.

As always, one of the greatest benefits of these gatherings is actually meeting local developers who work with or are interested in working with Ruby and Rails. It’s good for you, your software development career and the future of Accordion City as a hub for high-tech when gatherings like this take place, so be a part of it!

By the way, did I mention that the event is FREE?

Once again, the date is this Friday, September 19th at the Rich Media Institute (156 Augusta Avenue). The presentations will start at 6 p.m. and run until about 7:30. If you’re planning to attend, let Corina know at corecorina@hotmail.com.

Going Down Memory Lane with C

by Joey deVilla on September 16, 2008

July 25, 1994 issue of Time magazine
The July 25, 1994 issue of Time magazine.

The computer science student phase of my academic career (the less said about the previous phase, in which I was an electrical engineering student, the better) ran from 1991 to a successful conclusion in 1994.

If you are like me, you strongly connect memories with the music of the time; you could say that my computer science student phase ran from the time of Nirvana’s Nevermind and Soundgarden’s Badmotorfinger to Green Day’s Dookie and The Offspring’s Smash. Let’s just say that I often showed up to my classes and labs in a flannel shirt.

Album covers: Nirvana's "Nevermind" and Green Day's "Dookie"

(If that last paragraph makes you think “Whoa, that was a long time ago!”, you’ll be blown away by the fact that the initial work on C ran from the time of the Beatles’ Abbey Road to Led Zeppelin’s Houses of the Holy. A fair number of you probably weren’t even born then.)

My Student Language of Choice

I don’t know what the situation was like at other schools, but at the time, computer science students at Crazy Go Nuts University were allowed to hand in programming assignments using the following languages:

(Remember, there was no Java back then. The Green Project, from which the language/platform sprang, was still ongoing at this time, and Java was still going by its “Oak” codename.)

The general recommendation that came from most of my professors was to use Turing. They told us that it was a kinder, gentler language than Pascal and even more so than C, which they implied was designed by dyslexic aliens. When some of us suggested that it might be better to use a language that saw actual use in the real world, many of them countered with the argument that learning principles of computing was more important than learning specific languages. We might’ve responded by pointing out that one of our professors was a co-creator of Turing and probably got a vig for every Turing installation (it was a commercial language), but that might have been an academic career-limiting move.

I ignored their recommendations and went with C. In the lab, I used good ol’ cc. At home, it was Turbo C at first, and later, when I got my first Mac (a Quadra 660AV bought with money from DJing), Think C.

I never used C in my professional career. My first job out of school took me away from a world where input and output was all printf() and scanf() to interactive CD-ROMs and Macromedia Director (now Adobe Director and 7 versions later), and after that, the languages remained pretty high level: Visual Basic, Python, Java, C#, NSBasic, PHP and Ruby, with only a slight detour through through Visual C++ and C++Builder.

My C Books Back Then

Cover of "The C Programming Language"

It’s almost impossible to talk about C without mentioning “K&R”, the nickname for what is considered to be the official bible of C, The C Programming Language, which was written by Brian Kernighan and Dennis Ritchie. The latest edition of the book — the second edition — is a bit long in the tooth as it was written in 1988, but for the most part, everything in this book should still apply to the current C99 standard.

I never owned a copy of the book in my student days. I signed it out when necessary from the electrical engineering/computer science library in Walter Light Hall. I did own a copy for a brief period in 2002 when my deadbeat ex-housemate left a lot of his stuff behind, but I sold it (along with most of his stuff) in order to recoup some of the money lost from his stiffing me on rent, utilities, groceries and the largest domestic phone bill I’ve ever grappled with.

Cover of "A Book on C"

The books I had while at Crazy Go Nuts University were the second edition of A Book on C and Understanding C Pointers (a book that seems to be no longer in print). I liked A Book on C enough to pick up the fourth edition on sale a couple of years ago, and someone out there has forgotten to give me back my copy of Understanding C Pointers (you know who you are!).

Back to C

I’ve decided to get back into C for a number of reasons.

"Internet Tough Guy" Magazine

I have to admit that one of those reasons is completely irrational: it’s ego. There’s certain geek cred that comes with having at least some proficiency in C. While I had those bragging rights back in school, I can’t honestly claim them now; I haven’t even written a file whose name ends in .c in over a decade. Luckily, I had a pretty good grasp of C back in school, and the noodling I’ve been doing with good old gcc suggests that I’ve still got it, which is pretty reassuring.

iPhone, Arduino 480 and the "Mac Guy"

I’ve also been meaning to do some development with things that are programmed in C or C dialects:

  • The Arduino electronics prototyping platform has its own programming language based on C. I’ve been meaning to try out hardware hacking with the folks at the local group HacklabTO.
  • I’ve also been thinking about putting together some Mac OS X and iPhone apps, which require Objective-C.
  • I’ve even been thinking about doing some GTK noodling, which is done in good ol’ C.

Homer Simpson's brain x-ray

Finally, there’s the matter of just making myself a better programmer by working in C by refreshing my knowledge of the low-level stuff that C requires you to work with, and also the “brain stretch” that comes with working with a language and environment (what with going back to strong typing, compiling and make) that I haven’t worked in for some time.

I’ll be doing some C coding in my spare time, as well as noodling with the Arduino programming languane and Objective-C, and I’ll be posting my notes, observations and experiences here. As I’m fond of saying on this blog, watch this space!

Reg “Raganwald” Braithwaite: Alive and Well

by Joey deVilla on September 15, 2008

His blog presence is missed, but Reginald “Raganwald” Braithwaite is alive and well in real life. He and I work in the same building, and we’ve caught up with each other a couple of times recently. Here we are (along with developer/paparazzo Libin Pan) having dim sum at one of Kristan “Krispy” Uccello’s local developer lunches…

“Penny Arcade” on the Seinfeld/Gates Ads for Windows

by Joey deVilla on September 15, 2008

I like Penny Arcade‘s take on the current Seinfeld/Gates TV ads for Windows:

"Penny Arcade" comic on the Seinfeld/Gates TV spots
Click the comic to see it on its original page.

My favourite line from the article accompanying the comic: “Trying to associate Microsoft with “fun” is like trying to associate Satan with aromatherapy.” Mind you, I think they managed to pull it off with the XBox 360.

The first Microsoft commercial featuring Bill Gates and Jerry Seinfeld established them as oddball buddies in a commercial running one minutes and thirty seconds. In the follow-up, they’re living with a suburban family as an exercise in being in touch with ordinary people and weirdness ensues. The version shown below is the long one — it runs for four minutes and thirty seconds, and features a teensy bit of technology and tech terms (for a brief moment, Gates talks about object-oriented design) and another “Bill, give me a sign!” ending.
