Sharpening the saw with online competitions

Some time back Jeff Atwood wrote about Sharpening the saw on his blog. He defines sharpening the saw as (which is rightfully attributed to Steven Covey):

Sharpening the saw is shorthand for anything you do that isn't programming, necessarily, but (theoretically) makes you a better programmer.

There are several things developers can do to sharpen their saw. One of them is participating in programming competitions. There are several websites which host online programming competitions, and I really like this concept. Participants can work on these competitions at a time of their convenience, and those who do not have "real world" competitions hosted in their cities and towns, can also participate.

Code Chef publishes online competitions which can be solved in any one of 35 programming languages. I like the fact that they give developers freedom to code in their favorite language. Many other online competitions do not give this freedom, and impose a particular programming languages on participants.

All the problems published thus far on Code Chef seem to be mathematical in nature. That's fine and also understandable. Such problems have a definite output and can be easily judged for correctness. It can be a bit difficult to objectively judge programs which are more design oriented.

My math skills have really depleted since high school, so I am looking forward not only to sharpening my saw but also my math skills.

Interesting post, Parag.

TopCoder is another programming competitions site. IIRC it's only for Java. They also pay good amounts of money in prizes to the winners, and those who do well in the contests get chances to get commercial projects from clients, with whom TopCoder has tie-ups.

Re. TopCoder - forgot to mention - the level of the contests and the quality of the participants seems to be very high. Also UML is used heavily. There are often lots of Russian and other East European developers among the winners - I think it's partly due to their highly developed math and computer science skills. Pretty interesting site, overall, IMO.

TopCoder is also a nice website for online competitions. I have not yet checked it out, but I should.

I believe they also have several algorithm competitions in C and C++.

Didn't know that - thanks. Useful to know ...

Testing Groovy domain classes

If you are trying to test Grails domain class constraints by putting your unit test cases in the 'test/unit' directory, then your tests will fail because the domain objects will not have the 'valdate' method. This can be resolved in two ways: Place the test cases inside test/integration (which will slow things down) Use the method 'mockForConstraintsTests(Trail)' to create mock method in your domain class and continue writing your test cases in 'test/unit' What follows is some example code around this finding. I am working on a Groovy on Grails project for a website to help programmers keep up and refresh their skills. I started with some domain classes and then moved on to write some unit tests. When we create a Grails project using grails create-app , it creates several directories, one of which is a directory called 'test' for holding unit tests. This directory contains two directories, 'unit', and 'integration' for unit and ...

Running your own one person company

Recently there was a post on PuneTech on mom's re-entering the IT work force after a break. Two of the biggest concerns mentioned were : Coping with vast advances (changes) in the IT landscape Balancing work and family responsibilities Since I have been running a one person company for a good amount of time, I suggested that as an option. In this post I will discuss various aspects of running a one person company. Advantages: You have full control of your time. You can choose to spend as much or as little time as you would like. There is also a good chance that you will be able to decide when you want to spend that time. You get to work on something that you enjoy doing. Tremendous work satisfaction. You have the option of working from home. Disadvantages: It can take a little while for the work to get set, so you may not be able to see revenues for some time. It takes a huge amount of discipline to work without a boss, and without deadlines. You will not get the benefits (insuranc...

My first impressions of Python for the second time

I had worked a bit in Python many years back. Since then I have forgotten almost everything I learned back then. I think the phrase "Out of sight out of mind" applies perfectly to my mind. Since the last few days, I have started relearning Python, and this time I am recording my impressions of Python after having come to it from a Java background. Indentation: Python uses indentation to specify blocks of code, instead of curly braces. I like this, because we anyways indent code to increase readability, so why not achieve two tasks together. Code looks much cleaner without the curly braces. However there may be a little downside. Everyone in the team will have to set up their IDE's in the same way. Things might fall apart if some people use tabs and others use spaces for indentation. Access modifiers: Python does not have public, private, and protected keywords. Everything is public. However, private members can be specified with a leading single underscore. If we use do...
