Breaking the Fermilab Code

A story appeared on Slashdot about a mysterious fax received at Fermilab written in an unknown code. The full story is here. I looked at it and immediately noticed a few things:

1. The first part looked like ternary (base 3) with digits 1 (|), 2(||) and 3(|||).

2. The last part looked like binary with digits 1(|) and 2(||)

3. The middle bit looked like either a weird substitution code, or I wondered if it might be machine code.

4. In the last part the digit 2 (||) never occurs more than once, perhaps it was actually a separator and the last part is not binary.

The first step was to convert the bars into numbers. Here's a copy of my marked up print out:

The first part has the numbers (or at least I thought):


Noticing this had 113 digits (which is a prime number) I went off on a wild goose chase around primes, and then around the interpretation of this number in hexadecimal as a string in ASCII, Unicode or binary... waste of time.

Then I started thinking about ternary again and wrote down the largest ternary numbers that can be expressed with 1, 2, 3, ... digits:

23 = 210
223 = 810
2223 = 2610
22223 = 8010

One of those stood out: with three digits the maximum number is 26 and there are 26 letters in the alphabet! Then the only question was was how to map the three digits used in the code (1, 2, 3) to the three ternary digits (0, 1, 2).

To simplify things I wrote a small Perl program that tries out all the possible mappings and outputs the ternary interpreted as a string (with 001 = A, etc.):

use strict;
use warnings;

my $top = $ARGV[0];

$top =~ tr/321/abc/;

my @chunks;

while ( $top =~ s/^([abc]{3})// ) {
push @chunks, $1;

my @digits = ( '0', '1', '2' );

foreach my $d0 (@digits) {
foreach my $d1 (grep {!/$d0/} @digits) {
foreach my $d2 (grep {!/[$d0$d1]/} @digits) {
print "($d0$d1$d2) ";
foreach my $c (@chunks) {
my $v = 0;
my $m = 1;
foreach my $d (reverse split( //, $c )) {
$d =~ s/a/$d0/;
$d =~ s/b/$d1/;
$d =~ s/c/$d2/;
$v += $d * $m;
$m *= 3;
print chr( 64 + $v );
print "\n";

With my initial interpretation of the top part of the coded message I got the following output:

(012) [email protected]@[email protected]@CJQJFBWKAF
(021) [email protected]@[email protected]@FTVTCAPSBC
(120) [email protected]@RMPWRWJLFUNJ
(210) [email protected]@IZWPIPTXCOYT

A ha! The 021 block (which corresponds to the mapping 3 -> 0, 2 -> 2, 1 -> 1) seems to have a partial message: [email protected]@WOULD and then it's garbage. Going back to the original message I realized that 113 is not divisible by three and that I'd either missed a symbol, or had two too many.

After much fiddling around I discovered that the correct interpretation of the top block is that two of the threes are wrapped from one line to another (there appears to me some indentation in the message that indicates this, take a look at the original, but this could be just random).

323 233 331 112 132
333 231 322 123 312
111 331 132 312 233
333 212 123 213 113
311 333 313 331 113
113 333 232 322 133
231 333 112 123 133
231 312

Rerunning my Perl program output the full message:

(012) [email protected]@[email protected]@[email protected]
(021) [email protected]@[email protected]@[email protected]
(120) [email protected]
(210) [email protected]

So much for the first part. The second part took me off into Z-80, 6502 and 6809 machine code wondering if it was a program and then nowhere. I still don't understand what this part is trying to say.

The third part looked initially like binary but on closer examination I decided that the 2s (||) were actually separators and the message should be interpreted as number separated by 2s by counting the 1s (|). That yields:


(Once again there was a wrapping 'problem' in the message where a run of 8 |s was actually 3 |s then 1 || and 3 more |s.) Using the little Perl program reveals:

(012) [email protected]@[email protected]
(021) [email protected]@[email protected]
(120) [email protected]@NKVMNLUUKMUDYWKKB
(210) [email protected]@YSQZYXOOSZOHNPSSA

So, the same mapping between digits is used.

That leaves some final questions:

1. Who is Frank Shoemaker?
2. Why is base spelt incorrectly?
3. Is the extra S in BASSE a reference to the middle section where three symbols start with S.
4. If #3 is correct, then those three symbols could be intepreted as FC16 which is 252. Could this be the employee number of the author?
5. Why is the letter A missing from the middle section when all the other hexadecimal digits are there?


Unknown said…

It would appear that Frank Shoemaker is a physicist who worked on the BooNE neutrino experiment.
Douglas said…

Gives an email address for a FRANK C SHOEMAKER.

Random thought: the S could be the missing symbol for A, so the SDt => AFC_16 => 2812.
Employee 2812 appears to be EVERETT, ADAM ALEXANDER at Purdue University.
Adam Everett replied to my email saying that he is not the author, that his ID is not 2812 and that he believes that 2812 is not even a valid ID number. Looks like we'll have to look harder at 252.

Alex said…
"basse" might refer to the region in france?
I wondered about whether 'basse' might need to be interpreted in French. There is the region 'Basse Normandie', but more generally 'basse' in French means low, deep, bottom... If the writer is a French speaker then this could be a clue where they are saying that the employee ID is written in hex and at the same time making an illusion to the fact that it's the hex at the bottom of the block in the middle.

Interestingly, there is a Fermilab person with ID 252 (0xFC) called Pierre Piroué (he's a professor at Princeton).

I sent him a mail.
robf said…
I'm still at a loss for the symbols... Why, the symbol "key" itself must have a message and not simply for the "basse" sixteen employee number of whomever. An oddity in the symbol table is the lone Phi - 7... it's the only symbol I readily recognize. Flipping through about 30 some odd symbol sets from ancient times (cuniform, goth, runics, etc..) as phi pops up a few times in these sets, but I am wondering what made the choice for those specific symbols, or was it arbitrary from the author. this bothers me.
Unknown said…
Could be that phi is somehow alluding to the golden ratio
Unknown said…
Could phi be referring to the golden ratio (for some odd reason)
Unknown said…
Also I am wondering why "basse sixteen" is even mentioned when it's obvious to just guess this (for the 2nd paragraph) without even decoding the others (maybe this is noise to). I too am worried about "basse"... and "s.."...possibly the hex code has to be substitututed back in somewhere. For example may it modifies "basse" to reveal another number (only word would by forty or fifty, giving forty or fixty sixteen as the employee number). Just random thoughts :-)
BTW I sent an email to Pierre Piroué and he was kind enough to answer quickly, but, unfortunately, my theory about him was wrong. He denies being the author.
The capital Phi is interesting, and in physics it does have meaning (electrical or magnetic flux).
Torgeir said…
you ought to read up on slashdots article for an interesting take on the BASSE word (in the comments)..
Unknown said…
I suppose you've seen this:

note the references to "basse"
Marduc... thanks for pointing me to the new Slashdot story. I hadn't realized that they had linked here.

Marduc/Craig... the basse speculation is interesting. Perhaps this person simply worked in that building.
Unknown said…
Look at the first picture. It's a table of ANSI character graphics. I believe these are the characters in the second stanza.
Mike... I don't see all the symbols there, but perhaps a search of the Unicode tables would be interesting.
echaozh said…
maybe the ss in the word basse should be replaced by fc, making the word bafce (765902)?
pauljs75 said…
Caught this on slashdot, this seems like an interesting puzzle. Dunno if I can figure much out, but its fun to watch people solve this.

Googling "phi value encryption" gave something on RSA Alogrithm in the results that might be interesting. Dunno if there's other methods that use the phi value, but that's the first one that popped up.

Also note that the first two lines match up in spacing and pattern. So the legible text and line above it are possibly a key to the remaining encrypted text. I'd suspect that if you figure the offset of the readable line and the line above and use some encryption formula (just might be RSA) to further shift that, it might say something legible.

What I'm wondering is if there's something more interesting to it, or just some exchange between bored physicists with ciphers/cryptography as a side hobby. Another guess is that it's some thought out promotional stunt for using RSA encryption.
Unknown said…
How about this:
Unknown said…
maybe the 'ss' is refering to the German sign which looks a bit like the Greek beta symbol and is often replaced by 'ss' in typed text.

any Germans working at Fermilab?
Or perhaps it is coming from someone from a German research institute that worked with Frank Shoemaker?
This link has lists research centers:
for some reason, GSI drew my attention...
doing a search on 'element' brought me to the link for element 111:

you were talking about '2812'. Notice the pages that are mentioned in the link 281-282... probably a coincidence
Joachim Lous said…
The indentation in the first section is not random, nor is it significant: it's simply a 46-wide grid with linebreaks occurring sometimes before a space, sometimes after, and sometimes in the middle of a symbol.

Why 46? Might be just the number of cells per line on a sheet of ruled paper. My A4 pad with a 0.5cm grid inside significant margins has 47 cells to the long side.
Unknown said…
I was an undergrad physics major at Princeton 1970-74. Frank Shoemaker taught the big, tough Halliday and Resnick Phys 103 course, and later my group of majors advanced E&M. We knew he was a master at magnet design and construction.

Pierre Piroue was on the faculty then, so these guys know each other.

Shoemaker must be quite elderly now, in his eighties (I'm 56, and he had to have been at least 40 when I took his course in 1970.)

My guess is that the coder has a Princeton connection, but who knows?

I don't have much time left to work on this now, so I'm going to mostly sign off with the thought that this author has used ternary twice (top and bottom), so perhaps the middle is also ternary (although I've spent hours trying to decode it like that).
JHL said…
The characters appear one, two or three times in the second section (excluding the three non-key glyphs).
Bry said…
I believe the extra S in BASSE is designed to point out the significance of the S in the 3-char code. It's the only character not present in the 2 lines above. So what does sFC mean?

Subtract FC?
Swap F and C?
Unknown said…
IF Basse means low in french, maybe it denotes that the Hex is LSB, MSB.. i.e. CF(16) = 207 decimal...
Unknown said…
There must be a significance to the repetition of symbols in the middle section.
Gavin said…
Frank Shoemaker is working on the miniBooNE project which is looking at quantum noise ...
Unknown said…
I'm thinking the symbols in the middle are more of a pictorial puzzle. Perhaps if the employee number is converted to base 16 the corresponding symbols would reveal another message. For example E8C5 would form the word OIL if the 8 and C are combined to form the letter I (and you have to look in a mirror).
Stephen Jones said…
BASSE looks like a "calculator" word to me. If you spelled this in a 7-segment LED and turned it upside down it would read:
35549 or 35569
tedalan said…
what if the actual word "BASSE" should be interpreted as hex? Referencing S in the middle to correspond to "FC" yields BAFCFCE. The sentence could then read "EMPLOYEE NUMBER BAFCFCE 16". just a thought.
pauljs75 said…
Took another look at something in relation to how the placeholders line up in the message. So I'm gonna guess at something different.

Cipher: [email protected]@[email protected]@[email protected]
Key:????(Don't know yet)?????
Message: [email protected]@[email protected]@[email protected]

Now on the next four lines, notice how the placeholder @'s on the top two also line up with the @'s on the bottom two.

So let's try making the top two lines the code, and the bottom two lines the key. (or vice versa)


I'm not sure if a simple alpha grid is the right way... (ABC across, then from A, ABC down. Fill out the grid and rollover.) That seems like it'd be too easy to solve, but it looks like it might say something. So go down vertically on the left to J, then across to where T is. Now go back vertically to the top from where T is, and you get K. Etc, etc. Looks like it spells out some actual words, or perhaps a person's name. (At least from the first dozen letters or so I looked at. I don't have a straight edge and a printout to make following the grid easier at the moment.) But if it's that simple, then what's the middle part about?

On another tangent, somebody at SlashDot was saying "basse 16" could be actually referring to a building in a pecular way. (Something about the Wilson Hall design relating to some cathedral in France. Crazy stuff (almost like DaVinci code or something), but interesting none the less.) What if "employee number" wasn't an ID thing, but rather how many people were working there at the time the code was made?
Patrick Wall said…
Just a guess, but if we assume that the code on the top is talking about the top of the substitution code in the middle, then it's just noise. The bottom part of the substitution code should have the employee number in hexadecimal if you interpret it this way. If you look at the bottom part, it's all in hex, except for the S. So I'm just ignoring the S as an extra for now.

Converting Hex to ascii takes a pair of hex numbers, and without the S there are exactly 13 pairs of numbers or 13 letters. So translating:

F0 BE 58 F2 FD 63
6C 79 D2 E3 93 E6

gives us:


This is just a load of gibberish, so maybe there's a trick to it. The only hint I can think of is the extra S, which you can convert into the hex number 53. Maybe applying it in some way to the hex numbers will decipher it, but I'm too tired to think about it more.

has anybody noticed that the geographic position of basse-terre( the english wiki doesn't seem to know this...) a city in france is exactly

16° 0′ N, 61° 43′ E !
mantar! said…
And now ...

Something else to look at :)

Notice that in your final Perl decode of section 1, reading *down*, column-wise, the same string of "@@MMZZ" occurs after each(?) word break.

Have at it!
Unknown said…
Wilson Hall at fermilab has 16 stories, on the 7th floor it the 2 side columns are joined by cross overs.

Basse Ouevre has 7 columns on the back of it. in the 1st and 3rd stanza there are 7 sets and and an 8th partial. the Basse Ouevre's columns are in a semicircle, the center one could count as a 2 if you viewed the building from one side the other allowing the center column to double itself visually.

Rupert said…
Maybe the middle part contains a telephone number?

"FRANK SHOEMAKER WOULD CALL THIS NOISE" might be interpreted as "Frank S. would make a phone call to the number embedded in this (what seems to be) noise". Once connected, you'd have to ask for employee #252 -- or dial the extension.

The difficult part is finding a phone number in there...

Here are some ideas, but I haven't come up with any solution yet.

Replacing the 24 symbols with their respective frequency yields
311 311 323 232
311 222 312 233
or, with the usual modulo-3 mapping
011 011 020 202
011 222 012 200

that makes decimal
4 4 6 20
4 26 5 18
-- which doesn't look anything like a phone number.

Maybe each column gives one digit:
044255072806 or 044677056802
-- still not good

Maybe interpreting the numbers as letter as before and then dial that string using the letters on phone buttons?
DDFTDZER -> 33383937
-- still no luck.

(at least not if we assume that it is a US number)

All that assumes that the hexadecimal mappings are there only to decypher the employee number 0xfc -- and to give a hint to look at the frequencies, as it would otherwise have redundant entries.

Still, phone number or not, I think we are missing something obvious. The top and bottom part have been rather straight forward, almost simple. I don't expect the middle part to have some super-complex multi-layered encryption.
Daniel said…
Random thought:

What if BASSE SIXTEEN is a phone number? It works as a 10 digit phone number with a 2 digit extension... if you map the letters to the keypad of a phone.

Just a thought.

BTW: comes out to (227) 737 4983 #36 a Maryland Number... Lots of employees from University of Maryland there...

Has anyone tried to really decode the:

F0 BE 58 F2 FD 63
6C 79 D2 E3 93 E6


If we assume that it is a sequence of bytes and then decode it using the tertiary code of the other two parts, we will get ...

012 212 000 010 210 102 010 120 200 201 010 211

Is it possible that it's not a phone number but an integer sequence?

Aigars Mahinovs said…
About the phone number idea: 0 is often the extension to get to an outside line, +44 is the country code of UK, but in UK no phone numbers start with 6 or with 25. Dead end there, but don't assume that any phone number is from US ...
Unknown said…
Bingo, confirmed that my suspicion of the stars being flipped looks like it's spot on... I've got a good mapping of stars to 'noise' when it's flipped... Perhaps the code is actually written on a transparent film from a telescope?

If you're having trouble spotting it, polaris is to the right of the last line on the first paragraph.

Also, it might have some kind of filter, or perhaps not be optical, as stellarium doesn't have the small triangle of stars above the 4th character of the 2nd paragraph.

(oh, there seems to be virtually zero chance to match this to a time/date when it was taken as there seem to be many many dates when it appears to match up... either that or there's some trick to date-by-stars I'm unaware of...)

...what's bugging me is what do the stars have to do with frank shoemaker, or is it perhaps just coincidence that it was the nearest piece of scrap paper to the author at the time?
Unknown said…
Oh, agarius, how did you get that sequence of trinary numbers from the hex code?

When I did it I got:

Aigars Mahinovs said…
Could someone redo the decoding of the middle part assuming little-endian 16bit encoding (basse is supposed to mean 'low' or 'little' in French)?
Unknown said…
>F0 BE 58 F2 FD 63
>6C 79 D2 E3 93 E6

I think that should be read as:

F6 0C B7 E9 5D 82 FE 23 F9 D3 6E 36


6F C0 7B 9E D5 28 EF 32 9F 3D E6 63
iChaib said…
I just think loundly:

what if we consider that to be simpler than what it seems.
I think "basse sixteen" means the hex 16 in little endian.
starting from this we can have :
'employee number 620' (to octal)
'employee number 1021' (in hex)

please try to find if these ID refer to the author

My second thought is that the middle part is some machine code, and all the symbols are in fact just what Mr Shoemaker calls "noise", we just need to know that phi referes to 7 and S to FC
iChaib said…
I think the code is
F7 BE 58 F2 FD 63
6C 79 D2 E4 93 E6

it looks like some machine code that we can translate to assembly(I did some assembly last year and it seems to be similar to some code I saw)I'll try to translate it tomorrow.

Frank Shoemaker was the faculty advisor (Physics Department at Princeton) of Hugh Everett (the American physicist who first proposed the many-worlds interpretation of quantum physics). Hugh Everett believed in quantum immortality, so perhaps this is a message from him in another dimension! ;)

Could the S be E6(the combination of the two symbols corresponding to E and 6 made a symbol corresponding to S), so could it be :
"employee number E6FC" ?

or S.F.C stands for the Signature of Shoemaker Franck ?
Unknown said…
Someone touched on this on Slashdot, but the symbols in the second stanza were interesting. Nearly all have Unicode equivalents (some even multiple possibilities).

Here is what I found:
0=U+0069 (lower case i)
2=U+203A (single right pointing angle quotation mark)
3=U+29A3 (reverse angle)
5=? (looks like a circle, but with a mark on the lower right)
6=U+00AC (not sign)
7=U+03A6 (Greek capital phi)
8=U+2E07 (Raised dotted interpolation marker)
B=U+002D (minus sign)
C=possibly U+03BB (lower case lambda)
D=U+10E2 (Georgian letter Tar)
E=U+27D3 (Lower right corner with dot)
F=U+25C4 (white left pointing triangle)

It is odd to have the hex with the symbol. If you are going to hide a message in hex, doesn't that make the symbols redundant? The person that made this isn't that silly. Maybe the message is hidden in the unicode bits all combined, and the hex digit is actually some kind of checksum? Within Unicode, there are many similar symbols with different code. A checksum of some sort would be a way to ensure the reader has the right unicode for the symbol.

Andrew, I'm quite confident it's a mirror image of the northern hemisphere's sky, there's a very good correlation, check it out yourself if you don't believe me.

It's possible the things he's referring to are astronomical objects to be found on the image of the sky... eg, wasn't there a comet a few years back called 'shoemaker levy ' or similar?

I'm thinking it's possibly referring to an astronomical event that was captured on the film in question...

if you try to find a corresponding stellar constallation try
16° 0′ N, 61° 43′ E

i believe that it is more than an incident that this city is exactly at 16° 0' N. isn't it quite unlikely that the text reffers to basse 16 and this place doesn't have any thing to do with it?

Bingo, infrared survey of the sky here

shows up the 'missing' stars when compared to stellarium.

To the people who think it's fax noise, yes, faxes are noisy, but the correlation of the larger of these noise dots to star positions is way too strong to ignore! I wish I had a scanner here to show you the map and how it compares... Plus, there's the link to 'noise' that is referred to in the first paragraph, which given the almost perfect correlation I'm reasonably confident that's what they're on about.

The question to me is, is there more information to be had out of this star chart, or is the clue about noise just so we don't ignore the background image...
Unknown said…
Following the theory of a star map, if it is a mirror view of the northern sky, maybe we need to try decoding the 3 stanza’s mirrored so as to make them right side up when matched to the sky?

My boss used to work over at fermi lab next to Frank Shoemaker. After I told him about this he said the most likely meaning is that there are some younger less experienced physicists who have preliminary data that they want to publish but an older and wiser one is trying to point out that it could also just be outliers and noise. If you want to decrypt the remainder of the data, it might be good to look into the most “cutting edge” experiments that are going on over there at the moment.
raphael said…
maybe whoever sent this was trying to mean that some random data, which would be called noise by shoemaker, may contain information from outer space begin sent through neutrinos.
weberr13 said…
It is possible that my point is not clear. Many researchers when they start out are very excited by the initial data. It takes rigor and effort to rule out all possible sources of noise and more experienced researchers like Shoemaker have probably learned this the hard way. The message sounds like it is from an upstart who is upset that the old guard (who would have the low id numbers, since I verified that they are in numerical order--An id of 7xx was given to my boss 25 years ago so one even lower would be associated with someone who had been at the lab for almost 30 years) had put a stop on them publishing what they believed to be great scientific revelation because they simply didn't have the statistical basis to say it wasn't noise. What better way to make an ironic point than with an encrypted message that "looks like noise" but has some clever scientific information embedded in it.

“Employee number basse sixteen”
let’s decode “sixteen” using the midle stanza:
we can “draw” 16 using the symbols I, I > and ^, (try to put’em one to one)and if we take the hex corresponding to each symbol we have :
8863 or 8836 (6 = I>^ or 6 = I^>)
we have to separe 1 and 6, so we put 0 as separator:
80863 or 80836
but we have got “BASSE” which means in french “low” so we have to start with the lower symbol(which is >, note that we also have 3 lower than 6)
so our employee ID is : 80836N

Please check this ID, to see if I’m wrong or not(I think I’m not) or let me know how to check by myself.thx

Note: the employee ID at the fermilab is encoded on 5 integers and a caracter (C for Contractor, V for Visitor and N for Employee )

Try to look in the phoenician and and other semitic alphapets(arab, hebrew...) even the greek onevto decrypt the midle stanza
I made some interessting discoveries (the first symbol is the letter 'D' in phoenician alphabet...)

William Basse (c.1583-1653/4) was an English poet(notice that he lived in the 16th century) so perhaps the name of the author is William.

William Basse was also known as a follower of f Edmund Spenser(c. 1552 – 13 January 1599) ho was an important English poet that contribute mainly to the english poetry by his “Spenserian stanza” a stanza construct as this : 8 lines of 10 syllabus verse and the last line is an alxandrin (12 syllabus)

Did anyone notice that both messages are defining a character interchange key cypher (or however is said in english, i'm spanish :P ).
So, we have this:
(012) [email protected]@[email protected]@[email protected]
(021) [email protected]@[email protected]@[email protected]
(120) [email protected]
(210) [email protected]

Let's order it:
(012) [email protected]@[email protected]@[email protected]
(021) [email protected]@[email protected]@[email protected]


(120) [email protected]
(210) [email protected]

You can use this character interchange key to go from one to another sentence in a pair.
Ñ- no way you don't have these :P
Q-V (from the "garbage" lines, not from the sentences)

My guess: this is a key reminder, or a key exchange letter. The two "nongarbage" sentences may be a first cypher validation.

Any other thoughts?

You can contact me by leaving a comment in any of my blog articles.

Congratulations n0p .... you found a pattern....

Pity your observation is about a pattern between bit-shifted permutations of the same message...

Which means unfortunately the pattern you noticed doesn't mean anything.

cipher text is:

I'm going to start rotating through combinations to find the answer:

Notice a patter? Making the note that between each of these each char is char+1 isn't really interesting, is it?

Just a thought - wouldn't '[email protected]@[email protected]@[email protected]' actually /be/ noise? And everyone's barking up the wrong tree?

This might be silly but there are small dots, hardly noticeable all over the original picture that have a uniform pattern, could this provide some kind of clue or just wasting your time, at first I thought they were fragments on a dusty scan but they are in some kind of pattern, maybe the person was just doodling, thinking as they taped the page with the pen or it could be significant

Nicholas, not silly at all.

It's pretty clear it's a mirror-image picture of the sky, probably in the infrared spectrum (certainly it's not optical as there's a few extra features).

I'm guessing the message was written on a transparent film from an older telescope, but as yet I've been unable to get the image of the sky dated.

I suspect there's an interesting astronomical event in the image, but without a date am at a dead end.

Basse could also refer to this guy:
Hedgecore said…
Assuming 'basse' is French for 'low', what about a literal meaning - - 'low sixteen'. Perhaps it refers to an employee number "in the low sixteens" like 1601, 1602, etc.

The Basse building is interesting as well being that it is 16 storeys tall; perhaps there is some relevance to the lower stories (1 through 7 inclusive)?

I find it hard to believe that this would be a typo given the precision used to create it.

0xFC Is wrong.
0xCF is right. S stands for swap, swap F with C, employee ID = 207 maybe?
Callum Smith said…
SFC Means swap F with C meaning the hex 0xFC = 0xCF = 207

this also goes with chris's comment.

IF Basse means low in french, maybe it denotes that the Hex is LSB, MSB.. i.e. CF(16) = 207 decimal...

One thing I have not seen anybody do... is take that middle section, and group it into threes like everything else is.

If you take that, and turn it into trinary code like the rest, you get a really strange pattern. (replacing letters with zero and numbers with 1, or vice versa)

101 100 101 100 010 010 100 010 011 or
010 011 010 011 101 101 011 101 100

Notice a lot of the groupings are repeated... converting these to letters using the already determined code gives me gibberish though:


Seems far too coincidental to be ignored though...

Hey John,

Any thoughts on the 87A timestamps that have been found in section 2?

How to write a successful blog post

First, a quick clarification of 'successful'. In this instance, I mean a blog post that receives a large number of page views. For my, little blog the most successful post ever got almost 57,000 page views. Not a lot by some other standards, but I was pretty happy about it. Looking at the top 10 blog posts (by page views) on my site, I've tried to distill some wisdom about what made them successful. Your blog posting mileage may vary. 1. Avoid using the passive voice The Microsoft Word grammar checker has probably been telling you this for years, but the passive voice excludes the people involved in your blog post. And that includes you, the author, and the reader. By using personal pronouns like I, you and we, you will include the reader in your blog post. When I first started this blog I avoid using "I" because I thought I was being narcissistic. But we all like to read about other people, people help anchor a story in reality. Without people your bl

Your last name contains invalid characters

My last name is "Graham-Cumming". But here's a typical form response when I enter it: Does the web site have any idea how rude it is to claim that my last name contains invalid characters? Clearly not. What they actually meant is: our web site will not accept that hyphen in your last name. But do they say that? No, of course not. They decide to shove in my face the claim that there's something wrong with my name. There's nothing wrong with my name, just as there's nothing wrong with someone whose first name is Jean-Marie, or someone whose last name is O'Reilly. What is wrong is that way this is being handled. If the system can't cope with non-letters and spaces it needs to say that. How about the following error message: Our system is unable to process last names that contain non-letters, please replace them with spaces. Don't blame me for having a last name that your system doesn't like, whose fault is that? Saying "Your

The Elevator Button Problem

User interface design is hard. It's hard because people perceive apparently simple things very differently. For example, take a look at this interface to an elevator: From flickr Now imagine the following situation. You are on the third floor of this building and you wish to go to the tenth. The elevator is on the fifth floor and there's an indicator that tells you where it is. Which button do you press? Most people probably say: "press up" since they want to go up. Not long ago I watched someone do the opposite and questioned them about their behavior. They said: "well the elevator is on the fifth floor and I am on the third, so I want it to come down to me". Much can be learnt about the design of user interfaces by considering this, apparently, simple interface. If you think about the elevator button problem you'll find that something so simple has hidden depths. How do people learn about elevator calling? What's the right amount of
