[BLUG] Loan me a digital piano or synthesizer

This is really off topic, but you are people who I know and often
computers and music are skills that go together. Does anyone on the
list have a decent digital piano or synthesizer that they are not using
for the time being. I know a lot of people buy things an then they sit
around and collect dust. You can just loan one to me for 6 to 12 months
and then I'll give it back to you. Or I'll give it back to you if I
decide its not for me. Or if you have one that you'd be willing to sell
for cheap, I could take a look.

I have recently wanted to revisit my piano skills and want to make
sure I'm really into it before I pay $1000+ for a new one. I used to
own a Kurzweil PC88MX that I kept in great condition, but I sold it 6
years ago when I needed some money. So I know how to take care of these
kinds of instruments and I would take care of yours just the same.

[BLUG] Quicktime VR stuff

I know this is quite off topic and doesn't involve Linux at all, but
would anybody here happen to know of anybody local that does
panoramic/Quicktime VR type stuff? I have a client who is interested in
including some movies on her site, and I'm not really connected with the
local photographer scene...

Re: [BLUG] Running out of memory during log turnover

Is this always happening on the same time of the day?

If so, check your crontab(s) to verify that there isn't an unrelated reason
for memory to be low that time of night.

I know you're seeing the problem with Apache, but have you checked your other
log files? Sometimes a relatively minor warning in another logfile, at the
time that you're having the issue with main problem, can help you pinpoint
what is going on.

Cheers,
Steven Black

Re: [BLUG] Unix conventions for controlling file access

As others have said, this technique is decades old. There is nothing harmful
about it.

This technique is older than Linux, let alone the Ext2 file-system. Every
file-system for Linux has to support this, as it is an inherent
characteristic of Unix-like file-systems and our ability to do upgrades of
live systems (and perform rm -r / and actually delete everything).

Most security measures are about reducing risk. If you only have a temp. file
as an open-able file for a short period of time, it reduces the risk of
others snooping it on you. -- Especially when the names are picked truly
randomly.

Cheers,
Steven Black

[BLUG] Running out of memory during log turnover

Hello,

I'm wondering if anybody knows what I might do to address this problem.
I'm using FreeBSD and Apache is having a hard time when my Apache error
log files turn over causing Apache to crash with the following output to
my error log... No other logs of any sort on the system cause this
problem, but this happens consistently with my Apache error log:

Jul 14 23:00:00 netmusician newsyslog[81819]: logfile turned over due to
size>5000K

It looks like RT is a part of this problem consistently each time this
has happened... RT is setup to use mod_perl.

I've tried various Apache tuning techniques thinking that there was some
sort of memory leak, but I haven't been able to isolate this problem.
Since it is a PITA to manually have to restart Apache every time this
happens, I'm hoping that some of you may have some ideas as to some
things I can try here?

The other reason why I think this might be an Apache problem is because
of the several constant error messages that I see in my error log such as:

I'm not entirely convinced that my Apache install is healthy, although
it seems to behave just fine and I've noticed no real problems with
Apache. It has been perfectly stable, outside of this reproducible crash
caused by log file turnover.

I'm kind of grasping at straws here, I know.
