Well, as long as concurrent threads don't need to share mutable data or
single-use resources, there's no need for locking regardless of your
paradigm. What pure FP gives you is assurance, at the language level, that
this is the case.

FP doesn't necessarily involve GC. The ML Kit uses regional analysis of the
code to infer at compile time when memory needs to be allocated and when it
can safely be freed.

Sure, but even today you have choices other than Haskell if you want
faster performance. There's Clean (sadly, not free for commercial use),
and OCaml (though not purely functional or lazy), for example.

Subject: more colors on x with sis 530
i am using a linux sistem (2.2.6), with a xfree86 3.3.3.1 .
since there's normally no support for sis 530 on this version of x,
i am using the XFCom_SiS server.
everything works alright but the colors.
i can't get more than 16 bpp,and the more colorfull things on the
screen, the worse the colors get.
i believe the problem is that XFCom_SiS server.
am i right?
if i am is there any other server out there for my board?
if i am not right...
what can i do to get the whole 16 M colors?
thanks in advance

That's only a problem for packaging systems that check dependencies like
that. I usually compile from code, and rarely have library problems
despite having a Slackware system upgraded to glibc-2.1, with stuff
supporting KDE-1.1 and Enlightenment floating about. Usually, the only
problems I encounter are completely missing libraries; occasionally, I
need a major number upgrade.
I do have rpm installed - every time I use it, I have to use the
--nodeps option, as I didn't install my base system with rpm. It always
amazes me how specific the requirements are.

No. libglib.so should be a symlink to libglib.so.1.0.6: if so,
libglib.so.1.0.4 is obsolete and can safely be deleted. Run "ldconfig
-v" and read the output. That tells you which libraries are actually
being used, although you can work it out from the links. ldconfig
actually updates those links if you put a newer (minor version) library
in, although I'm a bit hazy on this.

No:
1) Don't use a dependency-checking packaging system.
2) Include the necessary libraries (as StarDivision supply glibc-2.0.7
with StarOffice 5.0 and 5.1), and run the program via a script that sets
LD_LIBRARY_PATH.
3) Write the application without using bleeding-edge library calls, thus
allowing the use of a wide range of versions. Package with rpm if you
like, but don't include library dependencies. Make it quite clear (via
installation program?) as to what libraries are required, with an option
to install the latest version (at time of packaging) if required.
Mark.

Subject: Linux systems- Poor security
Date: Wed, 16 Jun 1999 14:48:52 GMT
A while ago we had a security breach involving multiple linux boxes and
as a consequence, our IT staff will probably be implementing a ban of
the use of Linux! I use Linux as a development workstation (although
I'm not a UNIX expert) ... does anyone know why the security of Linux is
so bad? I assume that not all distributions are bad, but the ones with
poor security give Linux a very bad name ... infact they give all free
software a bad name .. I doubt if the IT staff will let me install
FreeBSD instead of Linux.

Hint 1: CGI= Common Gateway Interface.
SSI= Server side include != CGI.5
A Cgi program must generate *everything* including a Conten-type: header. The
following shell script is a correct CGI program.
#! /bin/sh
cat <<EOF
Content-type: text/html
<HMTL>
<HEAD><TITLE>CGI script output</TITLE></HEAD>
<BODY><h1>CGI outptut</h1>
<P>This output was brought to you by a CGI script</P>
</HTML>
EOF
SSI is like normal HTML plus some magic comments.
Hint 2: .cgi is not understood as anything unless Apache's
configuration files tell it to treat .cgi as CGI scripts (or
application/ms-word, aplication/pgp, etc if you want to be perservse).
Hint 3: Most ISPs do not allow there users CGI, period. Executing
things via SSI is out too because the same reasons lead to use of the
IncludesNoExec setting which allows all features of SSI *except*
execution of command and inclusiojn of CGI pages.

I'm using postgres 6.5, which is transaction-based, open-source,
and while not perfect, very good. A pleasant surprise after my
(short) experience with 6.4.2.
I'm using it to back a website, and knowing that my code can
catch problems and roll the db back to a consistent state
means I can program the site to be more robust. Or, at least,
to require a lot less fixing by hand on my part :)

Is the processor overclocked? This is a common problem if that is the
case. Also, you could have some bad RAM or the CPU isn't jumpered
correctly (Maybe an Intel jumpered as a Cyrix, for example) maybe the cache
module is bad. Perhaps you need to tweak some settings in your BIOS setup.
Sounds like a hardware issue, one way or another.

Actually, a PnP SoundBlaster is just fine under RedHat.. in fact is is
easier. You just put the card in and run "sndconfig" and it immediatly

What was the nature of the security breach? If it was truly a weakness in
the OS (and not easy passwords / less-than-competent users... etc.) than the
distribution you recieved must have corrupted it, because Linux itself is a
very secure system. Better than NT in my opinion... but I'm also a Linux

Personally, I recommend the Turtle Beach Malibu. It is well supported,

1) a 4Mb WaveTable, sounds good...but, not as good as the RAP10 I recently

It's actually (b), and that's my point. Denormalization does
not get rid of the need to do proper transactions - which was
the claim of the post I was responding to. Apparently you
agree with me.

So you have customer A and customer B. You debit A and credit
B. This needs to be atomic. A transactional system handles
that automatically. If you don't use a transactional system
you need to make those two db operations atomic on your own,
and guarantee it works.
Why bother when a proper db does it for you already?

Yeah...

What can I say? :)

I have an ftp site using wu.ftpd (standard ftp deamon which is shipped
with redhat) and would like to know how to allow users to access only
their home directory (i.e. their home dirctory on the box is their root
directory) when they ftp to the box.
any ideas?
Thanx in advance
Andy

I'm going to chuck another $0.02 down the bottomless well known as "offtopic":
First / Second / Third world refer to the order in which they developed modern
technology and associated cultures. Obviously this is insulting, but I didn't
make it up.

Subject: Session disconnects in a telnet session
Date: Wed, 16 Jun 1999 09:17:35 -0400
I am getting connected to a Red Hat Linux 6.0 box thru a telent session in
winodws NT. After around 20-30 min of inactivity with the telnet session,
Linux automatically closes the session. Is there a parameter to change this
time or disable this feature.
Normally there is a TMOUT that can be set in profile but I don't see it in
the profile (not in the /etc/profile too). I am using /bin/ksh as my default
shell.
Thanks for your help.
