Torrent Freeze
by Per Anton Rønning
Now I have experienced something odd. I am downloading F7 using
bittorrent. (It has been predicting about 16-18 hours of download time
which I guess is acceptable) I have in another thread discussed my
screen freeze problem, which now may or may not be expanding.
The PC usually freezes after some time of downloading, - well, it
freezes anyway after some time has elapsed - so it may not necessarily
be caused by the downloading as such.
But when I am about to pick up the downloading again, bittorrent-curses
starts out by checking the cintents of the .iso file which has been
downloaded so far. After a very short while the whole thing stops, and
reboot is the only option. This has happened 3 times in a row.
Does anyone have suggestions here? It may be the "old" problem of
course, but could this be some disk problem as well?

usb /proc/file permissions control
by jack craig
hi folks,
i just installed fc6, i got most stuff working, but am having a problem
with
a local tool. i have a usb widget that i plug into the usb port and its
recognized
and mounted.
however!! during this process, early in the setup, a file is created in
/proc/bus/usb/00x/00y with permissions of 644.
i want these files created with 666 just for the devil of it... ;-)
i have been reading the udev controls, but that says its for
controlling what is in /dev, not what is in /proc/bus/usb/..
i am betting a nickel that someone on this list knows the way to control
this file creation.
if you have any clues, pls share, tia, jackc...

Re: OT : Approximate / fast math libraries ?
by Globe Trotter
Btw, I usually use -O3 rather than -O2. I agree with the other poster: I am not sure getting rid of precision is a great idea.

Yes, I have profiled the code, quite extensively, using the valgrind/calltree
application. From this I know this that I'm know I've tidying up this to the
point where its hard to find big improvements, the cpu time is fairly well
spread around, not isolated in a few places. So am now looking a a few places
where math calls are taking more time than I would hope. I'm not going to get
factors in speed in the overall application, but I hope in a few places
things can be improvemed a lot locally.
Also, the project is not small, massive in fact, and I'm only writting one
small part. If you are interested you can find it here
http://lhcb-release-area.web.cern.ch/LHCb-release-area/DOC/brunel/release...
It also has to be supported on a *lot* of hardware. Basically gcc 3.2.3 based
Scientific Linux 3 machines, gcc 3.4.6 SL4 machines (32 and 64 bit) and (not
my decision), windows VC 7.1. I cannot rely on for instance SSE math calls
etc.
Taking an example from another thread, one place I'm trying to understand is
where I use atan2 see
http://www.hep.phy.cam.ac.uk/~jonesc/atan2.png
for the profiler output. atan2 is taking 50% of the time of this method. Not
here I don't need that much precision on the result - say +- O(2*pi/100).
Anything you can suggest here - The code is here
http://www.hep.phy.cam.ac.uk/~jonesc/RichPhotonRecoUsingCKEstiFromRadius.cpp
( note though its full of internal classes etc...)
cheers Chris

emacs resize hangs F7!
by William Murray
Hello all,
I amusing emacs on an up-to-date F7 box (emacs-22.1-1.fc7).
If I attempt to resize the window by dragging the border the input
freezes for minutes. I can move the mouse and watch my system monitor
colours scrolling, but cannot click on anything or type.
Sometimes it recovers, sometimes I press control-alt-backspace to
restart X. I don't see anything in the log.
Also, maybe related but far less reproducible, very similar behaviour
sometimes occurs when I switch workspace if I have a lot of windows
open. In that case the display is clearly wrong,
Does anyone know anything about this?
Thanks,
Bill

BASh help
by Mark Haney
I've got a script that's not behaving itself. I know it's something
silly, but I can't figure it out. The script is just a for loop that
runs through a text file list of files (/directory/filename format) and
does an 'ls' on each one. The problem is, I /want/ the script to NOT
find those files, i.e., those files shouldn't be there. That part
works, but I can't dump the output of that into a text file.
Basically ls dumps all the 'file or directory not found' straight to the
console and not to the text file when I redirect output to it:
./missingfiles.sh > testfile.txt
I get this output:
ls: cannot access /home2/test/20070829/KVNX20070829_225943_744_3.bz2: No
such file or directory
to the console and not the text file. How do I fix that?

Curiosity question for Electronic Engineers re: transistors ??
by Bill Case
Hi;
I have been reading up on the functions of CPUs. In particular, I have
found a lot of great info about MOSFET transitors. However, I haven't
been able to find (or if I have, I didn't know what I was looking at)
the levels (actual values) of High Voltage, Low Voltage and Threshold
Voltage used by a typical modern Intel or AMD CPU transistor.
If this is not a sensible or logical question, what should I be asking
or looking for? I just want to get a sense of the amount of electrical
input/output that is being used in processing.
I don't intend to build transistors in my garage and I am long past the
need to have help with my homework. I am just curious about computers.

help or recomendation for PCI-express graphics card
by Simon Tierney
I am still having problems with the system hanging at first time boot up stage after installing fedora 7 -it installs ok without error messages using an old matrox millennium G something pci card, but asks me to click an area to bottom right of the screen that is not visible at post installation first boot stage.
I can't seem to resize the screen and it hangs when I move the mouse to the edge of the screen.
Is there a way to get it to boot in text mode in case the default screen settings are too high definition for the card?
The system is tyan thunder dual opteron and has 1 32 bit pci slot 1 pci-express.
Has anyone experienced similar problems or can recommend a good (but affordable) pci-express card known to work with fedora 7?
