 It seems as if my system doesn't benefit that much:
 
 With 8 gigs of RAM, suspend-to-ram, preload and only a handful of rather
 lightweight binaries in regular use this system is already pretty fast
 with hdds only.
 
 I expected more WOW in terms of overall speed ...

SSDs are not a magic bullet, it's unlikely they will give you a killer 
performance improvement that makes you go WOW!!!

SSDs suck at random writes.
Typical usage scenario on a workstation is lots of random writes compared to 
relatively few random reads - reads tend not to be all that random as you 
re-read the same thing often and it gets cached.

Intel SSDs are far superior at random writes than any other SSD out there but 
it's still nowhere near as optimised as spinning drives, and kernels by and 
large are still optimised for spinning drives too.

This may account for your overall feeling of under-whelmedness why still 
seeing a significant boot-time speed up. You also have enough RAM so that 
almost an entire typical workstation session could fit in RAM and seldom touch 
the disk especially with a large interval between disk syncs

Re: [gentoo-user] freezing a package

  Create an local overlay. Put the ebuild in there.  
 
 I'd also rename the ebuild to something like
 
 my-nvidia-drivers
 
 That way it becomes a completely new app from portage's point of view
 and therefore not subject to updated nvidia-drivers in portage which
 you might forget to mask

That's a good idea, but it will require some editing of the ebuild as
portage uses the name of the ebuild file to determine things like the
download URL and where it is unpacked. As the version is not going to
change again, you could replace the $P* references in the ebuild with
hard-coded names.

Overall, learning to use package.mask properly may be easier :)

[gentoo-user] Switching AP from madwifi to ath5k

2009-12-20 Thread Grant
I've tried several times to switch from the madwifi wireless drivers
to the in-kernel ath5k.  Since I'm up to 2.6.32, I'd like to give it
another try.

It looks like wlan0 is starting in master mode and my laptop is
connecting to it successfully.  The problem is that shorewall won't
start (for NAT) because it says the loc zone is empty.  The only
interface in the loc zone is wlan0, which is started by hostapd
instead of the net.wlan0 initscript.  Shouldn't shorewall know wlan0
has started?  It doesn't check the initscript, does it?

Re: [gentoo-user] {OT} Preparing a laptop for sale

  Does the USB stick still boot? It looks like you wiped the wrong
 device.

 Bingo, right as usual!  Apparently I wiped the USB stick.  I ran fdisk
 and mk2fs -j again (do I want journaling?) and reinstalled Damn Small
 Linux on the stick.  For some reason the laptop tell me missing
 operating system when I try to boot from the stick now.  I need to
 test it on other systems.

 Grant,

 Take a deep breath and hhink about what you're doing for a second.  Did
 you just copy files to the stick and expect that it would boot?  It'
 still needs a bootloader (LILO, GRUB, SYSLINUX, or whatever) in order to
 load the OS on the stick.  Your dd wiped out *everything*

unetbootin does go through a step called Installing Bootloader.  I
also tried installing Super Grub Disk and Smart Boot Manager via
unetbootin, both of which are specifically described as bootloaders.
Still nothing.  Could that dd have wiped out something else on the USB
stick that is important for boot?

Is there a quick way to install a bootloader manually, so I can see if
that works?  I tried to adapt this but couldn't come up with a
procedure I though would be correct:

Don't know about the distro you were trying to install, but when I
need a bootable USB disk with utils, I usually go with System Rescue
CD

Maybe you forgot to mark the filesystem bootable?

[gentoo-user] [lame logrotate Q]

2009-12-20 Thread Harry Putnam
Can anyone show me how to write a logrotate rule that will rotate on
either size or age?

I use some very simple scripting for yrs but don't really see how to
rotate on more than one condition.

I'd like to rotate a certain log weekly or over 7000k and keep no more
than 12 rotations for whatever reason.

/var/log/debug.log {
   create 0600 reader wheel
weekly || size=7000k
rotate 12
postrotate
  /etc/init.d/rsyslog reload  /dev/null 21 || true
endscript
}

Is clearly NOT the right way to go.

Any know how to do it?

 Thank you. I have always wondered what the optimal bs might be.
 And why - could you possibly explain that, please?

 Is bs=4096 best for all disk-based operations?

 Many filesystems are set up with 4K blocks, so matching this with dd is
 more efficient. The default is 512 byte blocks and anything larger
 than this is good, I sometimes use 40960 but that isn't significantly
 faster. I prefer to avoid using dd on hard disks altogether, it's just
 so damn slow for large amounts of data.

 You can't teach a new mouse old clicks.


My *completely uneducated* guess would be that, for a raw disk level
copy (on a normal spinning disk) or write a bs that is *at the least*
divisible into the drive's cache size, and at best *is* the drive's
cache size, would be best. For SSDs, if you have some strange reason
to need to use dd with one (I'd avoid it simply because a: you'll
never guarantee an overwrite of what's really there now and b: you'll
be put at least a small dent in the lifespan of the drive) the minimum
erase block size would be best, since that'd allow both a full erase
and a full write of a block, rather than risking 2 erases to get all
of one block written.

I do reiterate that this is all mere conjecture, and is based in my
likely flawed conceptual understanding of the drives.

man logrotate has a few examples that may help.  Here is one.

  /var/log/httpd/access.log /var/log/httpd/error.log {
  rotate 5
  mail w...@my.org
  size 100k

I notice that the size part is on its own line which may be the issue.

Re: [gentoo-user] off-topic: logitech mice (MX1000)

 It seems to me that this mouse sends two button events for some of the

 Similar results for the many other buttons on the beast.
 
 Is this what the device actually does or does it signify a faulty X

 I have the evdev driver in my kernel.
 
 I use xorg.conf and have

As I recall, the fix for this problem is a sys-adm/lomoco.

Logitech mice actually produce those double events...  lomoco allows you
tell the mouse to stop.  I've got a udev rule for it, I think lomoco put
it there, but I've had logitech MX mice for years and lomoco is a fork
of a fork and may no longer contain the udev script.

You also might look into imwheel from the Mandrake distrabution as it
contains patches to deal with more than 10 buttons.
