t2′10 Challenge Solution

Tomi Tuominen — Tue, 07 Sep 2010 07:56:41 +0000

In real life it is not only about technical superiority but also how you are able to present your work. We feel that Mathieu Gaspard from France submitted an excellent write up that illustrates the Challenge quite nicely and accurately. So, without further ado here we go:

Solving the t2'10 Challenge - Mathieu Gaspard (Best write up)

The only thing missing is the easter egg - you might want to ask Peter Kosinar about that ;)

t2′10 Challenge Winners

Tomi Tuominen — Mon, 06 Sep 2010 19:50:27 +0000

Peter Kosinar from Slovakia was the first one to solve the t2'10 Challenge. The speed that he pulled off the Challenge was absolutely amazing. His solution was both fast and elegant. One could easily think that Mr. Kosinar has solved some other challenges in the past :)

The second ticket goes to Mathieu Gaspard, France (again). He is the official Mr. Elegance (again). His write up was extremely well written and included excellent screen shots and illustrations. We will publish his write up shortly.

Congratulations to both winners!

We would also like to thank everybody who attended. If you feel that you would have an interesting Challenge for t2'11 please let us know :)

t2′10 Challenge to be released 2010-08-28 10:00 EEST

Tomi Tuominen — Tue, 24 Aug 2010 18:36:00 +0000

Since the dawn of our species (well 2005, if you want to be picky about it) t2 has been granting free admission to the elite of their kind, the winners of the t2 Challenges. Don’t be suckered in by all the cheap imitations out there, their snooze-fest la-di-da dog and pony shows, because t2 is back! And we’re pleased to announce the release of the t2’10 Challenge!

Now is your chance to join the past elites by winning free admission to this year’s conference!

This year’s t2’10 Challenge is based on multi-staging (much like good shell code), which will be powered by a scoreboard so that you can see — (almost) in real time — how the other participants are fairing out there in the land of the living.

The rules are simple: t2 will release the t2’10 Challenge and the first one to solve it will win free admission to the t2’10. But don’t stop just because you weren’t the first one to solve it: The Advisory Board will select another winner among the next ten correct answers, paying particular attention to the elegance of the solution rather than the speed. In other words you can win with either speed or style :)

The t2’10 Challenge will be released 2010-08-28 10:00 EEST right here at http://t2.fi/

Merry Xmas and Happy New Year

We wish you all merry xmas and happy new year. As a Christmas gift we (finally) release the solution to t2'09 Challenge.

Tomi Tuominen — Mon, 05 Oct 2009 19:02:48 +0000

As promised earlier here are the winners:

Timo Hirvonen from Tampere, Finland was the first one to solve the t2′09 Challenge. The feat that he pulled off was absolutely amazing. His solution was both fast AND elegant.

The second ticket goes to Mathieu Gaspard, France. He is the official Mr. Elegance. His solution was well written and included (among other things) multiple ways to solve the Challenge Phase 2.

Congratulations to both winners!

We would also like to thank everybody who attended. If you feel that you would have an interesting Challenge for t2'10 please let us know :)

t2′09 Challenge Stats – EOF

Tomi Tuominen — Sat, 19 Sep 2009 19:40:01 +0000

This is the last post regarding the Challenge stats. We are sorry about the silence but basically the situation is exactly the same as week ago.

Around 50-60 contestants have been able to solve the first phase. Nine contestants have been able to solve all the remaining phases as well. So there is still room for one solution (if you are after the ticket that is).

We will wait two more weeks and will announce the second winner on 5th of October. So be quick and you will still have a chance to make it to the “elegance evaluation” round :)

t2′09 Challenge Stats – Week 2009-09-07 – 2009-09-11

Tomi Tuominen — Sat, 12 Sep 2009 14:54:35 +0000

Around 50 contestants have been able to solve the first phase. Nine contestants have been able to solve all the remaining phases as well. Congrats to everybody!

As stated at http://www.t2.fi/challenge/ the Advisory Board will select another winner among the next ten correct answers. The criteria for the other selection is the elegance of the answer.

So be quick and you will still have a chance to make it to the "elegance evaluation" round :)

t2′09 Challenge Stats – Weekend 2009-09-06 – 2009-09-06

Tomi Tuominen — Sun, 06 Sep 2009 19:47:02 +0000

Only three contestants have been able to solve all the phases of the Challenge so far. Congrats!

We would also like to remind you that if you are after a free ticket it makes sense to pay attention to your write up as the second ticket is given away to a contestant who is able to come up with the most elegant solution.

Please see http://www.t2.fi/challenge/ for details.

t2′09 Challenge Hint #2

Tomi Tuominen — Fri, 04 Sep 2009 19:00:10 +0000

The key is 8 digits long. No more hints will be published as it should be now pretty straightforward to solve the first phase.
