Another idea from colleague, is to bind the source address of the socket to the address of the desired netwrokr interface. While it doesn't guarantee anything, he said that in practice the kernel routed the packets through the desired network interface. On Tue, Mar 4, 2014 at 10:02 AM, Erez D w

Who's counting jiffies when all CPUs idle in NO_HZ mode?

(I'm talking now about MONOTONIC_CLOCK_RAW, not taking NTP adjustment into account) To my understanding, the basic time counting mechanism at the Linux kernel, is the jiffies counter. The way it counts time, is by leveraging a CPU interrupt happening at a certain known frequency. Every time this i

Re: Upgrading Ubuntu from 12.04 to 14.04

I'd urge you to consider using virtualenv to manage python dependencies. The only OS dependency you'd have, is python. You shouldn't care about dependencies beyond that. This is even more correct when deploying your application. On Thu, May 15, 2014 at 3:20 PM, Uri Even-Chen wrote: > Hi peopl

Beautifying latex documents

I want to produce a latex document template that looks similar to professional books' templates. That is, with notes bounded by a box of different color and having a picture on the top of the box. There's a book series with ants teaching you java and C++ with many examples for such a template. ther

Recommendation for a WiFi card

Indexing and search engine for website

Can anyone recommend an opensource website-search engine one can index his website and add a search capability to it with it? The most important thing for me is ease of use, minimum software requirements (that's why java-lucene doesn't really shines) the quality and speed of the search are less rel

ftp CHMOD permission denied

I'm having a site with ftp access, I accidently changed a directory mode to user write only. Now I cannot delete it or chmod it again. Anyone have an idea how to chmod it or get rid of it? Unfortunately the site is on godaddy.com which don't allow SSH access.

Time tracking software

Does anyone know a program, which, behaves like the old watches which kept track of worker's work time? IE, you tell it your name and "STARTED WORKING", or your name and "STOPPED WORKING" and it keeps track on how many hours did you work? ==

Hebrew morphological search

Does anyone know a working free/opensource implementation of full text morphological search in hebrew. Searching google results in a few results non of them seems maintained.

Re: Hebrew morphological search

I was looking for a more complete solution which already searches for morphological hebrew occurrences in database, or that incorporates in indexing solutions such as Apache's lucence or mysql's FULLTEXT search. On 1/21/07, Nadav Har'El <[EMAIL PROTECTED]> wrote: On Sun,
