wow i think i definitely have to get in on this although im expectig to fail dramatically it should still be alot of fun

maths isnt my strong point by far but im going to give it a go anyway looks like it should be fun and Newcommer92 is a close friend and he's good at maths so i may have to use him and his maths skills


thanks in advance Newcommer92
im sure you can do all the work and i can take the glory

Reposting with today's hint. Please note that "*" is shorthand for "times" and "x^y" is shorthand for "x to the y power".



Baseless Worries

"2339027659 120578267918 30490166
154816531992 154775609902 6025309
56407825711" - 229199170 1913176946889

Hints

1. You'll need a calculator and/or lots of scrap paper.
2. Each number separately encodes one or two words.
3. The title hints to both the coding and solution.
4. Division by 26 is required.
5. 27 = "BB".
6. 703 = "BBB" = 1*26^2 + 1*26^1 + 1*26^0

Okay, I admit I haven't even looked at this since yesterday


But I think I get it – let me see if it works out.

 


It works. I'm not gonna post the solution until tomorrow though, so that other people have a chance to give it a shot with the latest hint.

Ian - I think if I wasn't so preoccupied with the Debate Tournament and various real life stuff, I would have gotten it a few days ago. I just haven't been OCD enough recently

Very sporting of you ADB! Of course, it is my obligation to say: I'll believe it when I see it.


Other players, now's your chance to step up! The 1200-point clock is running!

Go ahead, americandingbat! You may post the solution…


No, I'm not giving up… I'll give myself some time before I check it out.
It now has turned into a personal battle: whether I crack the puzzle or the puzzle will crack me!


:bnghd:

(why am I sooooo persistent?... *sigh*)

"Baseless Worries" is at 1300 points and I'm glad to hear it'll fall soon. It can stop haunting me in my dreams now. lol.

Ian my friend, you are one sadistic meanie. "Thank you sir. May I have another?" LOL.

Okay folks, ready or not …

The first step in solving the code was to convert each number group from base 10 to base 26. To do this I used an online converter that I neglected to bookmark but I think it might have been this one.

The symbols used by the converter were 0,1,2,3,4,5,6,7,8,9,a,b,c,d,e,f,g,h,i,j,k,l,m,n,o,p

So the next step was to change a=10, b=11, c=12 ...

Then, just substitute the letter corresponding to each number to get the solution

Congratulations, americandingbat!

Well done. The 'trick' in the puzzle was, as you mention, the use of "base-26" numbering. Interestingly, every word in the English language can be represented as a unique base-26 number, which can then be converted to a base-10 number, as are normally used. In that manner, every thought that can be expressed as a sentence can be viewed as merely an ordered pattern of dots on the number-line. Imagine that!

The conversion from base-10 to base-26 can be tricky, involving lots of arithmetic. For that reason, I consider that the use of an online conversion tool to perform the necessary division, etc., does not violate Static Sky's rule forbidding the use of cryptography software. Basically, such pages are just a big pre-programmed calculator.

And mentioning calculators, base conversion is one of those tasks where modern 'digital calculators' like the kids are using nowadays are woefully inadequate. They insist upon performing division resulting in 'decimal point fractions', instead of the far more sensible result of an integer and remainder value.

Here is, as example, the 'by hand' method method of converting the first number in the code:


2339027659 / 26 = 89962602 remainder 7
89962602 / 26 = 3460100 remainder 2
3460100 / 26 = 133080 remainder 20
133080 / 26 = 5118 remainder 12
5118 / 26 = 196 remainder 22
196 / 26 = 7 remainder 14
7 / 26 = 0 remainder 7

7 14 22 12 20 2 7
H O W M U C H

Simply take the remainders from each stage of successive division by 26, and those form the base-26 'digits'.

Again, good job ADB, points will be coming your way upon Static Sky's approval!

I really didn't even think that might count as cheating.

If it's needed, I could scan the piece of scrap paper I used to convert the first word "by hand". I don't think it would prove much, it's pretty indecipherable to anyone but me.

And I went about it the hard way: first dividing by 26^6=308915776 to get the first digit, then multiplying the decimal part of that by 308915776 to get a number to divide by 26^5=11881376 to get the second digit …

I like your way better

No worries, ADB. Yes, the 'divide with remainder' function is hard to do on a calculator; I find I always divide, re-enter the integer result, multiple it back, then subtract from the original number to get the remainder. I think some calculator have a 'fract' or 'trunc' key, which makes it easier, but it's still a bother.

This is what I was using




It can add, subtract, multiply, and divide, but that's the limits of its powers.

 


So do we get more puzzles?

Hi-tech!


Oh I was going to wait until tomorrow, but I just can't... I will have a new puzzle posted within the hour (Static's already approved this one).


Edit: okay, well maybe it'll be longer than an hour; I'm still fiddling with it...

Great job Americandingbat and Ian is exactly right. This is definately not cheating. The rule is more to do with anyone just copying the cipher and pasting it into a decryption program and getting the points for no effort.

Using programs that do not specificaly solve ciphers, such as a conversion program like you described, is no more cheating than using a calculator. (Sad little one that you posted, though. LOL). 1300 points will find you later today. Congratulations!

And Ian, thank you for a very interesting code. I look forward to seeing how we all do with your next one. Cheers, my friend. Good luck everyone!

Thanks Static Sky. I have to tell you, this cipher making is a little trickier than I initially thought. It's much different sitting at this side of the table! I was surprised that "Baseless Worries" made it all the way to 1300 points - I actually thought it was a little easier that the previous puzzle! I am going to work on building hints into the puzzle, and other forms of deception, in an attempt to make things more interesting.


Attached is a puzzle that I really enjoyed putting together: "Dicey Ground". I hope everyone has as much fun being frustrated with it as I did! Enjoy:

From it's posting almost 2 hours ago, "Dicey Ground" is worth 500 points and counting.

Ian, I've too learned that it's a lot different sitting on the other side of the table. LOL. And I've got to say, brilliant work on the slick look of the new code. Top notch, buddy. Cheers!

And good luck everyone! I know I'll need some. LOL.

It's probably pretty useless to post something about an already solved puzzle but somehow I wanted to share my experience on "Baseless Worries". Who knows it might help someone…

I've used MS Excel to do the calculations. When Ian gave the last 2 hints, things had become a bit clearer. At least I thought so. He referred to a base 26, which is the same number of letters in the English alphabet.

I've created a table in which each letter would correspond to a number, starting on 0. All I had to do was to work on the groups of numbers, using base 26, to figure out some numbers that could be mapped on the alphabet.
I started with the 1st group, 2339027659, applying mod26 formula to reduce it to a number lower than 25. The result was 7. Then, I made a division of 2339027659 by 26, using the trunc formula. I've made as much iterations as needed until reach 0.

The result of the 1st group of numbers was: 7 2 20 12 22 14 7. This result appeared to be pretty reasonable. Decoding seemed to be at one step distance, right? Wrong.

Mapping on the alphabet (with vlookup
) I had: h c u m w o h

At that time of the night this sequence of letters didn't have any meaning to me. Perhaps some rotation on letters was missing or something…

I started then with the 2nd group. Surprise! I had a number error (#NUM!) when doing mod26. Apparently, excel didn't like this number…


At this stage, I gave up and quickly ran to ATS to check if there was already a solution… and…

Lessons learned:
1- Don't forget to read it backwards
2- Drink a coffee
3- Never give up

Congrats, ADB!!! (I heard something about a puzzle that you'll have to create for us in case you win the next one…
)

Great challenge, Ian! Thanks. Let's move on to the next one!

Whoa, hold on. Can I get a confirmation on that? I don't think Ian is ready to relinquish puzzle-design duties yet.

And Ian, very nice work on the new one. What an awesome mug
