Héhéhé, just FYI, LW 4.0.5 is very stable on os x, LW has been running without restarts on my imac g3 for the past 9 days as UP and uploading more than 12 gigs of data. LW memory and processor usages stayed the same over the days -- très bien :) Moreover, while I was away, I was continously able to get search results from my home computer from another computer running LW. Excellent! The only downside is that LW still increases the number of sources for a file not uploaded over the days, for exemple many rare files not once uploaded showed many sources in searches (it now increased to 30 sources per file!!!!) even if I'm the only one with them on the network.

Ciao

Edit: I think that each time my ISP changes my IP (a dynamic one and it changes often) the library adds one source (it remembers my old IP).

My optimizations have been found very impressive by the maintainer of GNU Crypto. I have posted them for free download on
http://www.rodage.org/pub/java/.

When compiled with the GNU "gcj" compiler, my SHA1 implementation shows an "impressive" rate of only 16 CPU cycles per byte on a Pentium III, according to the GNU Crypto author, as he also have other test vectors for the Tiger, SHA-1, MD5 algorithms, and he didn't report bugs to me, he will soon release an updated version of GNU Crypto with my new implementations, and I am working on SHA-256 (and SHA-224 which is a small variant), SHA-384 and SHA-512 (these 3 are part of the Secure Hash algorithms recently added to the american cryptographic standard, and approved too by the European NESSIE standard).

(SHA-512 and SHA-384 are very challenging to optimize for speed; lots of things can be optimized face to all the available implementations, but the number and complexity of binary expressions is quite complex; optimizing SHA-1 required lots of manual work that could not be automated by a generation script.)

Interesting. In my experience, 4.0.5 doesn't usually run for more than 24 hours at a time. I wrote a script to restart it , so it is no big deal, except for the people in the middle of a big download. I tend to get out of memory messages (even tho I have 512 Mb RAM) after running ~18 hours; I wonder if this has anything to do with it.
