March Contest Extended to 13th of March, 3 PM IST.

Posted by anup on March 9th, 2010 Filed in Announcement, Contests View Comments

Dear contestants,

As you all know there have been glitches in this month’s contest problem. Needless to say they were glaring and should not recur. We are sorry.

Life has come a full circle for us in the last couple of weeks. The other day we were basking in the glory of completing one eventful year and being so privileged to get all your patronage. We were bragging about our achievements! And now we have to face this to bring us back to our feet.

But we see a silver lining in this too. We have been inundated with lot of emails and feedback showing us how much you care. As we have been telling you time and again, we value each and every comment of yours and will certainly try to improve from here on. The kinks have been identified and we will now work with renewed vigor to get it all in place.

The “Traffic Jam problem” has been fixed and the scorecard has been updated. Please let us know in case there are still any discrepancies. We are extending the contest by a couple of more days. The contest now ends on 13th of March, 3 PM IST. We know that there is no substitute for the time spent by all of you on the problem. But this is the least we could do to try and be fair to all.

And do we need to say that we will need your continued support in our endeavor to make Codechef the way you want to see it? It will take us some time to get there. Please bear with us and be with us.

Keep sending your comments and let us know what you think and how can we improve further. Point out our mistakes but please do not hate us.

Anniversary Special : Programmer of the Year 09 – 10

Posted by basil on March 4th, 2010 Filed in Programmer of the Month View Comments

All our Programmers of the Month have been brilliant in their own way. While some performed exceptionally well in our contests, others have done a lot in contributing to the site.

This month, as part of our anniversary special, we are picking the best of our past POTMs and are giving him the title of Programmer of the Year 09-10!

Not only has Stephen Merriman performed consistently well in our monthly challenges, but he has also been a generous contributor to our site. We’d like to show our appreciation for all the tutorials, feedback and the consistent help he provides on our forums. Thanks Stephen!

Here’s more from the Programmer of the Year himself:

blog-potm-large


Name:
Stephen Merriman
Age: 23
Institute: none, though I can throw in a shameless plug for my work: http://www.cre8d-design.com
Userid: TripleM


Brief introduction about yourself (under 140 characters): Having not discovered programming contests until university, I now love them, and was very excited when I found a new one in CodeChef.

How/When did you start programming?
It’s quite hard to remember, actually. I remember making games in BASIC on an old Acorn Archimedes when I was very young, and then when my sister took some computing papers at university I would watch/read her textbooks. So maybe somewhere from 7 to 10? After competing in the IMO throughout high school, I never discovered programming contests until part way through university where I competed in the ICPC and found Topcoder among others.

What do you do when you’re not programming?
What do you mean not programming? Oh yeah, I do find time to play soccer during the summer, and attend a weekly pub quiz (sadly, there aren’t enough questions about programming for me to be any good).

What do you like most about CodeChef?
The contests, of course; I love entering any contest I can find online. Plus the fact that all those crazy targets at TopCoder don’t compete, so I actually have a chance of winning :)

How many hours a day do you program?
Seeing as my job involves programming all day, let alone the time I spend solving problems on SPOJ, CodeChef or competitions like the Codejam, it’s probably too large for me to want to think about!

What’s your favourite book and why?
This is going to sound a bit repetitive after Anshuman and Varun, but make that three in a row for Harry Potter; maybe there’s a connection between programming and magic? ;) I’ve always found novels about magic enjoyable. Plus, I have read all 80 something Agatha Christie murder mysteries (the link is more obvious there, problem solving <-> whodunit).

If you could eat dinner with any famous person (past or present), who would it be and what dish would you have?
Boy, that’s a tough one.. the dish would be roast chicken just because it’s my favourite meal. I’d have to think more about this but for now let’s say Fermat, just to see if he really did have a solution to Fermat’s Last Theorem.

What are your plans for the future?
Currently I’m perfectly happy with my job. I get to work from home for my sister, sleep in a bit, and make websites all day. I can’t see this changing any time in the forseeable future, but we’ll see how things go. Other than that – more top 5 codechef finishes, and getting as far as I can through the TCO + Codejam later this year.
