I'm guessing "rc" is the script or launching program for Cadence. This means either the installation didn't set your path, or you have to logout/login again so that the rc tool is in your path.
FC probably runs "update" on a daily basis, so by now you should be able to run
and get back one or two full paths -- one of which is probably related to your Cadence installation and which you should run (with the full path).
Hiya all
RE: My previous post on installing FC-3.
on a more serious note....
Is it always this much of a pain to install?
Or do I have a knackered CD drive?
(When it did the Cd scan at the start of the install - all 4 scanned fine 1st time tho....)
Please advise... as I'm thinking... (3 Replies)
Hello,
I am about to install Fedora on a partition on my hard drive. I got the CD from a magazine and it isnt a LiveCD so the magazine says "fedora core installer isn't a LiveCD, so it will merrily destroy your primary partition when you install on your machine", now I'm guessing the primary... (1 Reply)

bup-margin
bup-margin(1) General Commands Manual bup-margin(1)NAME
bup-margin - figure out your deduplication safety margin
SYNOPSIS
bup margin [options...]
DESCRIPTION
bup margin iterates through all objects in your bup repository, calculating the largest number of prefix bits shared between any two
entries. This number, n, identifies the longest subset of SHA-1 you could use and still encounter a collision between your object ids.
For example, one system that was tested had a collection of 11 million objects (70 GB), and bup margin returned 45. That means a 46-bit
hash would be sufficient to avoid all collisions among that set of objects; each object in that repository could be uniquely identified by
its first 46 bits.
The number of bits needed seems to increase by about 1 or 2 for every doubling of the number of objects. Since SHA-1 hashes have 160 bits,
that leaves 115 bits of margin. Of course, because SHA-1 hashes are essentially random, it's theoretically possible to use many more bits
with far fewer objects.
If you're paranoid about the possibility of SHA-1 collisions, you can monitor your repository by running bup margin occasionally to see if
you're getting dangerously close to 160 bits.
OPTIONS --predict
Guess the offset into each index file where a particular object will appear, and report the maximum deviation of the correct answer
from the guess. This is potentially useful for tuning an interpolation search algorithm.
--ignore-midx
don't use .midx files, use only .idx files. This is only really useful when used with --predict.
EXAMPLE
$ bup margin
Reading indexes: 100.00% (1612581/1612581), done.
40
40 matching prefix bits
1.94 bits per doubling
120 bits (61.86 doublings) remaining
4.19338e+18 times larger is possible
Everyone on earth could have 625878182 data sets
like yours, all in one repository, and we would
expect 1 object collision.
$ bup margin --predict
PackIdxList: using 1 index.
Reading indexes: 100.00% (1612581/1612581), done.
