BIG PROBLEM : MYSQL MAYBE

-------------------------------------------------------------

We are receiving many connections.
People come to us to view 1 image or text + 1 PHP content. Some other
people come to destroy.

Tasks to our servers :

1. Do we have to give the image ? = MYSQL Querry
2. Give the Image = Brandwidth
3. Give the text-content = PHP
4. Can you click on the image = MYSQL

Our web pages are displaid too slowly, like if we had an enormous
traffic.

We try to yze and modify DB Querries and Web codes.

yzing modifications, it appears that in a web page, inserting :

MYSQL (SELECT two fieds in T1 crossed with two fields in T2) is not
consuming a lot of CPU for the MYSQL process BUT is consuming a lot of
CPU for the HTTPD process. Maybe bc of the time to get results.


What are the leveraged actions to embeed the speed of the web pages ?

1. Minimize requests to MYSQL
2. Minimize PHP readen content (e.g.
while(isset($_COOKIE['$j'."$i"]) ....)

Many thanks for any advices from your knowledge and experience.

fix for sys_vmsplice exploit: how to?

Learn to recompile your own kernel. Learn to add a new kernel file to
your GRUB boot loader configuration. Learn how to select which kernel
you are booting in the GRUB menu. Then you will be eligible for one of
the 98 different patch files I have available based on kernel version at:

http://phil.ipal.org/linux/kernel/patch/vmsplice/

Or see if your repository source for package updates has a new kernel
available for you if you're not in the "geeky learning" mode.

Today most distros have Postfix or Exim as default MTA.
 

It's much more convient to have a MTA that is responsible for
sending mail than to configure every program you may want to send
mails with. Just like having a printer server instead of telling every
program how to print.
 

fetchmail can invoke procmail too. That's how I get my incoming mail.

 

Sionce they have m4 macros to build the sendmail.cf all the common
things are quite easy.

 

If your hardware can handle it 10000 users shouldn't be a problem for
any serious MTA.

One of the reasons I really like Dell is the ability to look up the service tag and get the machine specs, doentation, and downloadable updates. No registration is required, although it is handy to do so.
 

It's handy for server class machines, too. I'm dealing with a number of older server class systems right now and finding Dell's support sites helpful.

Oki-Doki !
The described behaviour is doented in numerous bugs that date back 2 to 3
years (!). Ist appears to emerge out of the combination of kde & xorg-7.2.
I upgraded to xorg-7.3 and everything works like expected. No additional
modes required, rotation and dimension correction work seemless.
This makes my TC1100 tripple the fun, especiall ywhen using "dasher" for
text input :-)

mp3gain

Posted: 11 Feb 2008 06:44 AM PST

"Doug Freyburger" <com> wrote 

Thanks for another helpful reply. Now I understand why the command ran
in batches of ~1750 mp3s.
 

You're probably right. I'm going to let it get all the way through in
batches and see what the results sound like. Most of the batches end
halfway through an album, which should provide some continuity anyway.
If I end up with some particularly loud or quiet I can always run
mp3gain again on those individual tracks.

It's taking about 2.5 hours to process each batch (2 hours to yse,
..5 to rewrite them), so it hasn't finished yet. I run the server
headless so need to find another PC I can log in from and leave
running for ~17 hours for it to complete. I'm not aware of a way to
let the process continue after logging out. I could always schedule it
as a monthly cron job I suppose ...
 

Yes. Sadly mp3gain is quite limited, and doesn't have this feature -
but never mind, I'm sure the xargs solution will be fine. If not, I'll
do what you suggested earlier and output all the path&filenames to a
text file, randomise it and then feed it to xargs again. That should
ensure the convergence of gain across batches.

Thanks for all your help,

file recover on reiserfs partition

Posted: 09 Feb 2008 03:06 PM PST

In comp.os.linux.setup Chris Cox <net>:
[..] 

To me it has proven as the most utter crap FS I have ever used,
whenever some FS failed you could be sure it was reiserfs.
Replacing it with something know to work fixed all FS related
problems for all times. My best advice, don't use reiserfs.

Linux vs OS X vs "Other alternitives"...

I don't know about MSFT products. But I've a few OSX machines mixed in
around the Linux machines. Updates are very different, but still
reasonably straightforward and flexible.

I do miss the CLI tools when using OSX (and the ability to run "yum
list ..."), but it may be that they're there and I just don't know them.
And I've enough complaints about OSX's differences from other Unixen
(little but big things, like automounters and such) that I tend to keep
my OSX time mostly to a minimum.
 

Redhat's RHN is not quite as flexible as yum, but it's not bad in terms
of flexibility or functionality. It's still based on up2date, which is
backward from yum but not *that* far back. My big complaint against it
is that, unless I go for a higher end service I believe, I cannot simply
rsync RPMs to a local archive from which a bunch of machines can be
updated.

It's been a while, but my recollection of Solaris' pkg support mechanism
- just to add another example - is that it was pretty feeble. It would
check dependencies, but not act on them. That is, an install/update
might fail for missing dependencies, but it wouldn't pull the
dependencies in.

But that was quite a while ago; things have probably changed since then.
