And I'm redirect to group "comp.lang.python" if I need help. For "gmane.org"... too long for access help... Askari

Two O(n) passes [I'm assuming reverse() is O(N)] beats O(n^2).

want recommendations - distributed storage modules?
by aum Aug. 1, 2004

Aug. 1, 2004

Hi, I'm looking for a python-based framework for distributed storage. Needs: - high redundancy - high probability of being able to retrieve data even if (say) 30% of nodes are down - pure-python implementation - peer to peer - no central server requirement - 3rd-party module requirements - none, or pure python only - scalable A Distributed Hash Table (DHT) implementation would probably suit best. However, the only DHT implementations I've been able to find for python, such as SharkyPy and khashmir, are both broken on my box, and are under-documented and apparently unsupported. Any recommendations? Cheers aum

SFTP file transfer library
by Lothar Scholz Aug. 1, 2004

Aug. 1, 2004

Hello, at the moment i have a program that uses FTP but some clients want to use the FTP over SSH protocol. Is there a library that does this ? And also where can i find the protocol specification. I never used SSH very much and only know how to start a SSH shell from my windows client.

Thanks. I'll check that when I get time. Until then, malloc gets the blame until proven innocent, since profiling and test output turned out nothing else that was different.

popen4 poll problems
by jim_8421＠hotmail.com Aug. 1, 2004

Aug. 1, 2004

Hi, I noticed with popen2.Popen4 class, sometimes the poll() method will keep returning -1 although the command has finished. However, when a read is done ( ex. p4instance.fromchild.read() ) and then a poll is done, poll() will return the process exit value. Why does this happen? perhaps I have to do some type of flush before doing poll? Thanks in advance Cheers, Jim

The newbies here (myself included) don't learn anything, and IMO, that what the newsgroups are for, to pass along hints, tips, and knowledge from people who DO know what's right and what's wrong. How about an example? Thanks Ruben

Re: language/distro preferences

I use Gentoo. Their portage system is really, really good. Being able to download and install programs and all their dependencies, using my compilation options... that makes life so much simpler... And about PHP, I hate it. The language is so weak. Nothing is OO. The libraries are inconsistentand everything is in a big mess, due to the absence of namespaces. I guess this is best illustrated by the following example : Python #1: if char in string: do stuff if item in array: do stuff Python #2: print mystuff.getsomestuff().getsomeattribute().getname().capitalize() PHP #1: Um, which of the 50 string functions should I use ? (lookup help). Um, I don't remember, should I put the haystack or the needle first ? It depends on which function you choose. Um, does it return false, O, -1, or null on failure ? (It depends on which function you choose) Um, what's the function name for an array ? is it find_array or array_find or in_array or array_has_key ? mmm... what if the key is a string... is it a different function... mmm PHP #2 : $temp = $mystuff->getsomestuff(); $temp = $temp->getsomeattribute(); echo strtocap or somthing( $temp->getname(); ) You get it ?
