Why Programming Competitions Could Be The Future (But Probably Won’t)

(Disclaimer: This post features somewhat stronger opinions that the usual so I have to be clear that while I manage the programming competitions in DevCon, the sentiments in this post do not represent the organization’s.)

Algorithm/Programming Competitions: the other type of “Hackathon”.

When you see the word “hackathon” nowadays, it refers to the one where a bunch of people are gathered into a single venue and form groups to work for a couple of days on ideas that they pitched at the beginning and end with a final pitch to see how good their prototype and idea is. Best pitch wins.

On the opposite end there’s the original OpenBSD type of hackathon. People are still gathered in a single venue, but there is no pitching – just coding. It can be a directed coding venture, like in the first hackathon where they worked on some parts of the OS. It can also be a creative, free-form one, like Global Game Jam where game developers make any game for 48 hours as long as it’s somehow related to the theme.

There can also be prizes in the latter, but it’s mostly a fun exercise for developers. And there’s no business stuff and pitching to worry about.

Programming Competitions have nothing to do with these two. It’s only because hackathons have become somewhat famous spectacles recently that people think that “get programmers in a single venue and make them code” automatically makes it a “hackathon”.

A programming competition is a race. First team to make programs that can solve the contest problems wins – it’s as simple as that. No pitching. Strict rules. And a lot shorter than most hackathons.

I believe that Programming Competitions have the most potential out of these three programming events…

Programming competitions are an objective test of programming skill. If your program doesn’t solve the given problem, you won’t get a point for it.

Compare this with college. As weird as it may sound, you can graduate with an IT-related degree without knowing how to program, whether through deception or through plain incompetence of the school. And this happens more than we’d like in the industry.

Let’s imagine programming competitions somehow become famous throughout the country in a few years time. Not basketball-level fame, but maybe soccer-level. Say there’s a persistent online Philippines-only HackerRank-like competition where anyone from the top-tier universities down to the remote colleges can test their skills. Assume that the anti-cheating and user-verification measures are good enough that graduates can put their “programmer level” on their resumes and that employers will honor it.

Imagine what would happen if students are confident of their programming skills that some of them even show them off. Imagine its impact in the industry and the academe.

It’s going to be a crazy world, won’t it?

Certainly a bigger impact than what the other hackathons can do.

…but given what we have right now, there’s very little chance that potential will be reached.

The opportunity is there, but there are hurdles that may be too much for anyone interested in taking it.

First problem: no one cares.

Just a quick background: I’m not a competitive programmer. I solved programming problems (Project Euler, topcoder archives) back in college just for fun. I never practiced for or competed in any live event other than the odd Google Code Jam where I never intended to pass multiple rounds.

But I understand the importance of testing students for their programming skill. After the DevCon Code Challenge Cup, I decided to code a quick online judge in Rails and in mid-2013 started to hold mini-programming competitions in various schools around the country. You can try out a demo here.

And after 2 years of doing this, I’ve had a couple of striking revelations.

One of those was how little people cared about programming. Sure, the people who invited us were really grateful to have the opportunity to test the programming skills of their students, but very few of the organizers were curious about the problems given to the contestants. I would understand the hands-off approach if they were school administrators, but many of those who invited us were IT students and teachers.

None of them reviewed the problems before I gave them to the contestants, checking if the problems were too easy or too hard or simply out of scope of their curriculum. Only a couple of them asked me about the problems after the contest even though that would have been the best time to ask for advice to improve their programming skills.

And there you go, the reason why we’re churning out weak IT graduates: the people in position don’t care about things that they should be passionate about.

The previous problem is compounded by the problem at the other end: a lack of understanding of the relative skill levels of programmers.

Programming isn’t a sport, it’s a skill and a craft. It’s not easy to gauge programmers and we are left to use vague terms like “beginner”, “skilled”, and “expert”.

And anyone who conducts a programming competition to non-competitive programmers will see that “beginner” is not adequate for describing college students. They’re all beginners, but the difference between their skill levels can be great.

Yes, that’s a euphemism for “college students suck at programming”.

Go to the demo link above and read the problems (if it’s still in Practice mode, wait until the Contest mode starts). Even though the problems can be answered by anyone who has just taken CS classes on Java programming and algorithms, in our experience only students from the big 3 universities were able to consistently answer more than 7 questions within the time frame. The next tier of universities can answer around 5, while the rest even struggle with 3.

If aren’t a programmer and don’t know how easy it is to answer just 3 in that list of problems, let’s just say anyone taking a good Programming 101 class should be able to do that in 4-5 lab sessions.

So yeah, most college programming classes are horrible. If you’re going to hold an open (non-invite only, non-ACM-ICPC) programming competition today, you ought to lower the difficulty of the questions. Otherwise, many of your contestants will get very low scores.

You don’t want that to happen. Put yourself in the shoes of someone who either was just curious or was pressured to join the contest. What will they think when they leave the event getting only one or two correct? Will they look forward to the next competition? Will they help promote future events?

Maybe, but probably not.

Even now, I still occasionally get cases where contestants get depressingly low scores (especially if I’m not familiar with the school). We’re lucky that the contests are confined within the schools so we don’t need to worry about negative publicity, but this brings up another point: unless you’re like me who can conduct more than one contest a month, most programming competition organizers do not have the experience of holding contests on a regular basis to learn from their mistakes.

Combine all these three points and you’ll have an idea what will happen when someone conducts an open programming competition in the same manner as the other hackathons.

Venue, logistics, sponsorships… no problem. Then they’ll find people who had past programming competition experience to be the judges and write the problems for them. But since it’s the first time for all of them, the judges will write difficult problems and the organizers will not look at the problems.

Fast-forward to the end of the event. Many teams joined, but only a few of them were competitive programmers. One of the latter won, and the rest were left with a score of 1 or 0.

There won’t be any negative PR (it’s not like it was a bait-and-switch), but there won’t be enough positive buzz either to make a bigger and better follow-up event. Instead of spreading the word and encouraging more people to join in the future, many will just go home and say “eh, at least I tried” and leave it at that.

On to the final point.

When you’re in my shoes as someone who has programmed over half of my life (a good chunk of that professionally) and as someone who recently has conducted programming competitions, you’ll come to hate programming competition-level problems.

I hold programming competitions in schools to show students that they need to understand their programming skill level and work on improving that to the point that they are comfortable with it even under pressure. This is the skill that I want to cultivate into students, and it will do well for them as they enter work.

But there comes a point where the problems are just too tricky that it’s no longer a test of programming skill, but a test of knowing trivia from Computer Science and Math that you will almost never get to use in the industry.

Simply put, high level programming competition skill does not equate to high level software development skill.

High level programming competition also relies on quick hacks – computationally efficient, but ultimately ugly kludges. Good Software Engineering requires you to avoid these hacks lest they become technical debt that will cripple your system and your team in the long run.

Another thing, the deeper you are into complicated problem solving, the more prone you are to The Complicator’s Gloves.

This pitfall of forgetting the original goal of having open programming competitions can be avoided as long as your organizers and judges are developers from the industry whose years of experience have removed any romantic feelings for CS trivia in favor of more pragmatic approaches to software engineering. But then again, there are far fewer CS/SE hybrids (i.e. well versed in both) in the local scene than Developer/Designer “unicorns” so good luck finding them.

Long story short, Programming Competitions are one of those things that look great on paper, but immediately reveals why no one does it the moment you try to do it on your own. (see also: local Developer Bootcamps)

Can anything be done to address the problems above and push these contests forward and take Philippine IT students’ skills to the next level?

Of course. But it’s going to take a much more dedicated and passionate group of people than what we have right now.

Free HTML5 Game Programming Book (almost) Out

Two months ago we had an HTML5 game workshop. Weird stuff happened and I ended up being the substitute instructor for the Phaser workshop. Also decided to use Leanpub for handouts instead of my usual slides.

I got a positive response out of it and went on to spend a couple of weeks fleshing out the book.

Last week, I released a heavily updated book and started spreading the word. The book ended up getting to top 3 of the most downloaded books for the past 7 days:

Here’s the link to the book: HTML5 Shoot ’em Up in an Afternoon

Any feedback about the book and helping spread the word would be greatly appreciated. :D

Math in Programming (again)

I’ve discussed this before but another thread popped up a couple of months ago and I had to give another explanation on the significance of mathematics in software development.

Excuse me?
I just want to ask if the computation in math is using for programming? Cause I hate Math :-|

Almost all programming deals with logic, and Logic is part of Math. So yeah, you shouldn’t be a programmer if you don’t want to do math.

But I’m getting ahead of myself… the real question here is: “Why do you hate math?”

If you hate math because you think it’s all memorization and weird symbols, you do not hate math – you simply hate standardized education from last century.

I love math, because for me it’s a fun way of exploring and discovering the mysteries of the reality we live in using only a handful of tools. I do not consider the memorization and weird symbols as the whole of math, I just think of them as a necessary (albeit annoying/painful) part of math – no different from a novice carpenter getting injuries from learning his tools.

The problem with most math classes is that they are too abstract to the point that learning the topics become almost faith-based. (A good example of faith-based teaching can be seen in Richard Feynman’s essay on Brazilian Physics eduction.) If students were introduced to calculus using this or polar coordinates using this, they might have a different opinion on the subject.

Back to your question, the other commenters have already given most of the things you need to know i.e. no, most of us programmers don’t do hardcore math from day to day; however, learning math practices your abstract reasoning and problem comprehension skills, both of which you will use everyday. (Think of soldiers doing push-ups. You won’t see them do those in the heat of battle, but it helps condition their bodies for the battlefield.)

Oh, and yeah, there’s one field in software development that everyone wants to get into but actually deals with a lot of hardcore math: Game Programming.

Aa. Okay i just want to ask if that math subjects is so hard to get? :)

They are hard, but they are doable as long as you have proper study habits.

Different maths require different skills, though. For example, Linear Algebra is more meticulous to detail, Calculus stresses your pattern recognition abilities, and Discrete Math needs both critical and out of the box thinking.

So You Want to Teach Ruby and Rails…

RubyConf Philippines was a blast. I still can’t decide which of the following was the best thing I did in the event:

So yeah, I did a talk on the first day about teaching. Here are my slides:

I recorded an “extended podcast-version” earlier today. Here it is in all it’s crappy one-take glory:

Some quick links for further reading:

Free Rails Book at Leanpub + RailsFTW update

A month and a half to go to build up my street cred for RubyConf PH

Seriously, though, I’ve spent the past month working on stuff related to my upcoming talk, namely, about teaching Rails. At the top of the list was converting and formatting my old outdated Rails 3.0 book to Leanpub‘s markdown dialect.

Long story short, the book is now available there for online viewing. I’ve also gone the Humble Bundle-esque “Pay-what-you-want” for e-books scheme for people interested in giving me money to support my other writing endeavors.

In other news, I’ve finally updated RailsFTW to Rails 4.0.2 and Ruby 2.0 (2.1 is still unstable for Windows). Head over to the site and grab it while it’s hot.
