Hola gente,

Perdonad por el off-topic pero creo que a más de uno le puede interesar :)
Se trata de dos charlas que dará Russ Cox, que está en el MIT y trabaja con la
gente que hizo UNIX, C/C++ y Plan 9, en Bell Labs.
Una en la autonoma de Madrid y otra en la rey juan carlos.
Las dos el jueves que viene día 24.

Al final del mensaje hay punteros sobre como llegar y demas.

Peer-to-peer computing: a new direction in the design of distributed systems

Traditionally, distributed systems are architected as central servers
serving many clients.  Recently a number of Internet applications
(such as Naptster, Gnutella, and Freenet) have demonstrated the
benefits of a peer-to-peer architecture, in which clients
cooperatively provide a service, without relying on central servers.
The benefits of a peer-to-peer architecture are fault tolerance, load
balance, and the ability to harness idle storage and network
resources.  Accompanying these benefits are a number of design
challenges.  A peer-to-peer architecture should be symmetric and
decentralized, and should operate well with unmanaged volunteer
participants.  Finding desired data in a large system must be fast;
servers must be able to join and leave the system frequently without
affecting its robustness or efficiency; and load must be balanced
appropriately across the available servers.  While the peer-to-peer
systems in common use solve some of these problems, none solves
all of them.  This talk discusses Chord, a peer-to-peer system built
at MIT, and how it solves some of these problems and others.

Security in Plan 9
 
    The security architecture of the Plan 9 operating system has recently
    been redesigned to address some technical shortcomings.  This redesign
    provided an opportunity also to make the system more convenient to use
    securely.  Plan 9 has thus improved in two ways not usually seen
    together: it has become more secure *and* easier to use.
 
    The new architecture is centered around a per-user self-contained
    agent called factotum.  Factotum securely holds a copy of the user's
    keys and conducts authentication protocols (both native Plan 9
    protocols and legacy protocols like APOP and SSH) on behalf of the user.
 
    I'll describe the Plan 9 architecture and also talk about ongoing work
    in applying the lessons of factotum to Unix systems.
