> Bill Ricker, Perl 5.24 & Abe Lincoln's War Cipher
Last month, I did my usual Cryptographic History talk before
BLU.org's GPG/PGP keysigning.
The title was "Transposition Cyphers in Historic Context", looking at
a theory and two specific uses, President Lincoln and German Army
Corps WW1.
As usual, there was a bit of Perl code used for demonstration - for
Lincoln's. This time, I used the 5.020 experimental features that
we've discussed in new release feature reviews: postderef and
signatures (both promoted to stable in 5.024 so safe to use in real
code).
BLU saw the history, but this month, Boston.pm gets to see the code.

Note NO NOVEMBER tech meeting - 2nd Tuesday in November in a Leap year
is Election Day - I presume most people will be watching a different
channel that night. Do we want a different night or week ? We usually
do social in December.
Boilerplate details
Tech Meetings are held on the 2nd Tuesday of every month at MIT
building E51, Sloan School Tang Center [not the other Tang building!]
nearer to Kendall Sq than Mass Ave. (directions).
Talk begins at 7:30.
Refreshments in the hallway prior.
RSVP for count encouraged but not required, to
bill.n1...@gmail.com or Boston-PM list, by 4pm Tuesday.
FUTURE
* NOV * (2nd Tuesday in November in a Leap year is Election Day, i
think we'll skip, that'll be a busy news night for folks. Worse
competition than World Series or Olympics. We can pick an alternate
date or do a weekend social or off-week social.)
Tues Dec 13th, room E51-376
