[HAIFUX LECTURE] The Book of Bad Crypto Decisions -- Orr Dunkelman

On Monday, July 21st at 18:30, Haifux will gather to hear a talk by Orr Dunkelman:

    The Book of Bad Crypto Decisions (part 1 of 1,000,000)

Abstract

The borderline between cryptography and computer security (or "How to 
use cryptography") was, is, and will be, a place for many problems. In 
this talk we shall go over several of the (many) examples to "what might 
get wrong", and discuss how to avoid them (and how to mitigate them).

The examples will cover GSM's security (with several lessons), issues 
with random number generation, how PKI can be misused, etc.

=================================================================

We meet in Taub building, room 6. For instructions see:
http://www.haifux.org/where.html

Attendance is free, and you are all invited!

==================================================================
Future lectures:

04/08/14 Cedalion: A Democracy Awaiting the People: Boaz Rosenan

==================================================================

We are always interested in hearing your talks and ideas. If you wish to give a talk, hold a discussion, or
just plan some event haifux might be interested in, please contact us atwebmaster@...

Haifux, this Monday, on crypto-hell

Hello all,

On Monday (July 21st), Haifux will mock those who had good intentions 
but poor crypto wisdom, and deserved their position in the shameful list 
of security fails. And also discuss why they got it wrong...

The short abstract is at http://www.haifux.org/lectures/328

This is an extra announcement, as the lecture was added recently.

See you,

     Eli

Backing up to encrypted Blu-rays

Hi all,

I just wrote the following documentation on backing up to encrypted
Blu-rays:

http://troubleshooters.com/lpm/201408/201408.htm

When your backup discs are encrypted, offsite backups are much safer.
Everything in the documentation applies equally to dvd backups.

Hope you enjoy it.

Thanks,

SteveT

great
this is the closest as it gets to what i wanted
only caveat, is that if the system is modified, it will not merge like 'patch' does
however, i can live with this

than, on another system which has a copy of the old dir tree (and
possible some modifications), i need to patch it to make it a 'new'

what i would like to have is somthing like rsync, which can create a

Not only about that, but about allowing me to create such future artworks and essays, while becoming financially independent. I'm OK with getting a part time job, but I refuse to be a wage slave (and it's mentioned in the link).

Please donate even if it's just a dollar or two, and please help spread the word, if you found my stories, aphorisms, articles and essays (including the blog/Twitter/G+/Facebook/Reddit/etc. posts) of inspiration and enlightenment. I want proof that there are good people in the world.
