Two words: Alan Cox
http://www.linux.org.uk/diary
<snip>
Another two words:
Learning Curve
I'm new to Linux. I'm new to Unix. I _try_ not to be a luser.
The .rpm approach has got me up and working with various
packages pretty fast. I would probably have given up without it.
As it is I have a working system which gets booted to Win about
once a week, if that.
No I don't know all the details, but I'm learning on a running
system. In other words rpm has flattened the learning curve for
me.
I still use Agent under Wine for news, but I'm working on
understanding INN. I now use Lyx for document production. I use
Navigator for the web...
I could never have got so far so fast without a system like rpm.
It may help attract the 'dumber than an average ameoba' crowd,
but hey, what a little colateral damage between friends? :-)
Nothing in this world is 100% good or bad. Thats where the
'rabid dogs' amoungst the advocates go wrong. Even the 'anything
but MSoft, but give me a MSoft clone' lusers aren't 100% bad,
at least they are showing half a clue in rejecting MSoft.
Verdict on rpm: Good tool, but can be misused/misadvertised.

I have a problem with Insure++, and i don't find any answer neither on
parasoft web site, neither in the documentation.
here is my problem :
I'm on an IBM AIX 4.2
i compile and linking my program with Insure++ to make shared object for
Netscape Server.
I haven't any error message during compiling or linking, but when I try to
launch my server, i have the following error :
conf_init: Error running init function(late) load-modules: dlopen
of /bin/webserveurs/applineteurossl/saf/applinet.so failed (dlopen(): exec
format error (errno = NOEXEC))
and when i launch the program using the shell, i have a similar message :
exec(): 0509-036 Impossible to load the program applinet.so for due to the
following reasons
0509-023 Symbole _Insight_stack_call in ksh undefined

Hello,
I get sporadic system crashes during a X-session. Thus I can't get
any oops or panic messages, as the text-console is not restored. Is
there
any analysing tool to find out what happened after I pressed reset,
similar
to a system-dump on solaris, or something?

That is definitely the truth. My worst problems to date have been
with mistaken reference counting (in an on-the-fly model-checker.)

System III cron had that problem. I remember one hilarious day when the
guy across the hall at work (Geoff Kuenning at Callan Data Systems, in case
he is reading this) noticed that for some reason his clock was set about 14
years behind. He su'ed and set the clock. His disk light lit up solid, and
his system got real slow. Cron was trying to start around 5000 UUCPs.

Subject: RedHat's X-Windows Requirement
Date: Tue, 06 Apr 1999 18:09:00 GMT
I have just tried to install Red Hat 5.2 and given up. Like previous
versions of Red Hat's installation program, it refuses to allow me to
not install the X-Windows system. A few noteworthy complaints:
1) When the installation program tells you that package(s) need other
package(s) to work properly, it does not allow you to remove any of
the packages at that time. You have to go back and remove them from
the (rather large) package list.
2) The installation program does not give any hints about where in the
(rather large) package list the specified package resides. If it is
one of the (many) packages that could be in many places, then you have
to subject yourself to a very long search of the package groups.
3) There is no way (that I have found) to remove the XFree86-VGA16
package. It is simply not an option.
4) (This one is not specifically directed at Red Hat:) Some packages
that should not require the X-Windows libraries require them anyway.
It seems that somewhere along the line, graphics routines were put
into the X-Windows libraries instead of into their own libraries. So,
packages that do not need X load up the libraries to use the graphics
functions. Someone should have put their foot down and noticed that
graphics can (and should) be seperate libraries that the X-libraries
depend on, not the other way around.
5) Many of the packages do not say that they need X or are even X
programs, but instead say that they are GUI as if GUI is the same as
saying X. I find it hard to believe that anyone could be so arrogant
as to say that X is the only GUI out there. It is quite easy to
develop a GUI package that does not rely on X.
These are just a few of my complaints (comments, objections?) about my
attempts at a Red Hat installation. If I just said "go ahead and
install the X-Windows libraries" I could install Red Hat. But as
someone (I don't remember who) has in their signature, if Linux
doesn't do what I want, then I can change Linux, not the other way
around. I don't want to install the X-Windows libraries (just because
I don't!), but if I want to use many console applications (such as
print filters), I am forced to install them anyway. I would
personally love it if someone would seperate out the graphics
functions from the X-Windows libraries since they do not need to be
together. Until then, I will be forced to install files I do not
want.
NOTE: I am going to try to install Debian next. It is (slightly)
easier to remove X from Debian than from Red Hat. However, their
installation floppies insist on trying to auto-load drivers for the
WD-7000, which locks up on my system... (sigh)

HURD can be installed on either ext2fs or UFS, IIRC.

It's almost certainly sysv (unix system V, Release 3.2 v 2.0 sounds quite
like an old SCO Unix version). The problem is that Linux doesn't know how
to handle the SCO partitioning style - SCO uses one big partition and sub-
divides it into slices. Your best bet is to obtain a "free" SCO Unix
OpenServer license and recover the data from there. Take a look at
http://www.sco.com for more information.

A trivial answer would be to say that each one of the crontab lines
will only be exec'd once, which seems fairly reasonable.
