Description

Clothing optional keynotes, comparisons to the pains of childbirth, the joys of sharing an office, how to give a 90 minute speech minus PowerPoint and only writing 130 lines of code, and why PDC is the most special developer conference on the planet . . . this is one amusing show starring PDC keynote speakers, and developers by day, Chris Anderson and Don Box.  Not to mention, Mike introduces a new PDC Hard Hat Challenge! 

PS:  The brainteaser from last week remains unsolved – will you be the Mensa member who can finally crack the code??

      What a fun episode to film! While all of our keynotes are sure to be chock full of developer goodness (tm), I think that Chris and Don will be a blast to watch. They have a great sense of humor, and they're true geeks.

      Also, as the description notes, last week's Hard Hat Challenge remains unsolved. I've added a few hints to the comment section if you want to take a stab at it. Good luck!

      Is there a way that you can share the picture that you showed in the video in this thread... Thanks.

      Orand...we use a kitchen timer to keep the show short and tight. That's what you may have seen Jennifer dial at the beginning of the video. The timer tends to run a bit fast, which is why it went off at 9:24. I suppose we could explain it at the beginning of each show, but we've probably gotten lazy by assuming that everyone has seen our prior shows.

      Chris and Don are *always* worth my time. More. More. More!

      Mike, could you post the image as text maybe? You see I am too lazy to type it down or to download some OCR software...

      Let's see if the geniuses at StackOverflow.com can help us out with the code deciphering. Smiley

      Here are some interesting stats from the cipher they flashed on the screen:

      There are 708 characters in the cipher, excluding new line characters.

      Given a chunk size of 3 characters,
      • There are 236 chunks.

      • There are 172 duplicates.

      • All the characters are numbers between 2 and 9.

      • The 323 code shows up a whopping total of 29 times!

      • The 333 code shows up 11 times.

      • All other codes show up 7 times or less.

      • 35 chunks start with a 2.

      • 200 chunks start with a 3. (Interesting!)

      • 1 chunk starts with a 4.

      • Despite the cipher containing 2s, 3s, 4s, 5s, 6s, 7s, 8s, and 9s, chunks only start with 2 and 3, except the 1 chunk that starts with 4.

      • There are no 0s.

      • There are no 1s.

      • There are 115 2s.

      • There are 293 3s.

      • There are 56 4s.

      • There are 38 5s.

      • There are 49 6s.

      • There are 52 7s.

      • There are 63 8s.

      • There are 42 9s.


      The 323 code is very interesting indeed. I'm leaning towards chunk sizes of 3 being involved somehow. We'll see!

      How many tables are at ask the experts?

      More than 200. http://www.microsoftpdc.com/Agenda/UnSessions.aspx#ask-the-experts

      Cheers,
      A 15-yr old kid from Hungary who now feels cool.

      PS. I will be posting how to solve it in a few hours.

      Congratulations, palotsab! You have indeed validated your geek credibility. Great job. Please send us an e-mail at pdccount (at) microsoft.com, and we'll coordinate your very limited edition PDC2008 internal t-shirt. I can't wait to read how you worked through the Challenge. Smiley

      So, I was on the right track with the "chunks of 3" thing. Cool. But I wasn't able to solve it.

      Just finished talking to palotasb (Boldizsar) above who solved it. He posted a discussion of how he solved it at his blog.

      Wow. Nice solve. I'm blown away by his hacking skills. 15 year old, of all things!

      Congrats on the solve!

      Thanks for the link to palotasb's blog, Judah. And great write-up, palotasb! You even recognized the small "clues" at each step...very impressive.

      I'm working on this week's Challenge as we speak. It should be another fun one. Smiley

      Wow cool... Smiley I was also thinking for it being some kind of Base<something> encoding in the end... But really cool how he solved it Smiley

      Sorry, didn't realize someone had already solved it:)
