How about just removing floppy A?  If they want to mount a floppy they
can use B.  The only real question with this is whether the
non-existence of A will send the boot prom into terminal panic (I
confess that I haven't tried this).  If this does work, I would
further suggest removing the devices for floppy A do prevent the
kernel from ever trying to read a non-existent drive.

I am not sure if we are thinking the same thing. In up-coming gcc 2.2.2d,
which I am planning to release this Sunday. There is only one version of the
shared images, which is used by both jump table and good, old shared lib.
If you use -jump in LDFLAGS, your executables are linked with jump table. The
good, old shared lib is used by default, which uses the same shared images
but bypasses the jump table.

My my. Aren't we getting rather jumpy lately? I'm not trying to single
these two out, but there has been a lot of "complaining" and flaming
responses in return. comp.os.linux is turning into a regular shooting
gallery.

Do we all drink too much coffee? May I please suggest to those who are
awful quick to post flames and counter-rebuttals that we are over-
reacting.

theory #1> Most of the folks who allegedly "bitch" are new to either
unix, usenet, Linux, or social skills. These naive, innocent people
do not deserve the pouncing on they sometimes receive.

theory #2> Some alleged "bitching" are from people who are making
casual observations or bringing out to light some ideas that might
make things easier or more understandable. These people do not deserve
soap box speeches on how they should do it themselves or take a hike.

theory #3> Those posts which are true-blue complaints that have no
excuse, should either be ignored, or flamed in private (e-mail).
The poor sap could easily ignore the flaming responses in the
newsgroup, but if you fill up his mailbox or however he gets his email,
it's not so easy; therefore, it is more effective. Don't clutter the
bandwidth with it.

It is a shame that the psychology behind the net allows otherwise
mild-mannered people to turn into raging fiends and bash and burn those
who "irritate" them, all because they are hidden behind the fascade of
the network.

So, please, gentlepeople, I beg of you: think twice about flaming that
poor soul who made you believe that you are so superior. We are all
human. Just ignore him. He'll go away. Or send (email, not post) him/her
a polite message in an honest effort to straighten him out. If you need
to blow off some steam, then write an inflamatory note using four-letter
words that would make a sailor blush, and then mail it to dev/null.

Oh, and don't flame me because I fall into both theories 1 and 2.

Well, I think the only way to correctly test thi is to run the BYTE
bench again. Especially the 'concurrent shell script' part. I didn't
do this yet, but I had a very strange experience with the jumptables
yesterday, and it is reproducible (so far).

I compiled the 'flops.c' V1.2 program thas has been posted to
comp.benchmarks last february. This is a program, as the name implies,
that tests the FPU and certainly not the library. On my 486/33 results were:

   gcc -O6 -N -s -o flops flops.c        ===> 1.65 Mflops

   gcc -O6 -N -s -o flops flops.c -jump  ===> 1.70 Mflops

(Note that I didn't try to -m486 the thing... yet. And: yes: I know that -O6 is 
not better than -O2)

I didn't believe this, so I repeated it many times. Is there any one
who has an explanation for the fact that the '-jump'ed executable is
3% faster? Could this be caused by a difference in the crt0.o?

For the people that are interested in performance, some more results:

   gcc -O6 -N -s -o flops flops.c -jump -fomit-frame-pointer -funroll-all-loops
                                         ===> 1.80 Mflops

   gcc -O6 -N -s -o flops flops.c -jump -msoft-float
                                         ===> 0.60 Mflops

Ok guys, what say someone organises a whip around to pay off this beast.
It seems to me that there are an awful lot of people around that are
using Linux, and getting a lot of fun and interest out of it, and for a
small trouble we could pay off the machine, and allow Linus's mind
fuller scope to spend on the problem in hand rather than the monthly payments
on the box. Perhaps as a gesture of saying 'thanx'. I realise that there are many
other people that also contribute, but after all, Linus started this game.

Whoa - you're talking an entirely different type of security breach.
I know that here at Lehigh, we have the machines physically bolted and
locked to tables; we had a printer stolen recently, but the people
smashed the entire case and took the insides (in other words, they
didn't get a functional printer).  Software security is one thing, but
if your site is such that people can simply walk in, open the machine,
and take the hard drive, you've got an entirely different type of
problem.  Booting from floppies then becomes the least of your
worries, no?

Yeup, that's also true.  I do own one of these, but I haven't tried.
I've been trying to figure out how Diamond selects the clocks for the

   | 	I am just wondering if there is a port of xsetroot to X386 yet. If there is
   | where can I find it? I couldn't find it with the X386 distribution(version 1.0)

     I'm getting a bunch of stuff to upload to the ftp sites, ported by a
   new Linux convert. Xsetroot may be among them. I know he did the icon
   editor and a few other things (antfarm?) in the last week. I expect to
   get a bunch of stuff from him on disk this weekend and will upload it
   when I do.

Um... xsetroot is in the core distribution of X11.

if you're using X11 v1.1 (or v1.0) from zorst, try getting the xextra
package from the same place you got the base X11 binaries. (if you got
it from banjo, reggae.oit.unc.edu is replacing banjo, so try there)

If not, just ftp to export.lcs.mit.edu and cd to
pub/R5untarred/mit/clients and type 'get xsetroot.tar.Z'

xsetroot is there along with about 40 other clients that come with the
core distribution...
