I mentioned this problem at the last round-table session, but didn't get
a solution, so I thought I'd post it here, just in case anyone has any
suggestions to offer.
I'm still seeing a whole bunch of false positives in SpamAssassin, since
an update was installed in mid-September on a CentOS 5.7 system, for a
rule called DATE_IN_FUTURE_96_Q, which is only supposed to be triggered
when the "Date:" header has a date that is 4 days to 4 month ahead of
the date in the "Received" header that …
[View More]has the _smallest_ difference in
date.
Here are the headers from the latest e-mail I've received with this
false-positive. (I've stripped out irrelevant headers, for the sake of
clarity and simplicity.)

Note that I'm calling spamd via the spamass-milter on a system running
sendmail. Note also, that in the above example, the only "Received"
header was the one generated by my own server. (I've had other false
positives, however, with multiple "Received" headers, all of which were
within seconds of the time in the "Date" header.)
Any ideas?

Does anyone have a spare ATX power supply? Mine seems to have a problem.
Specifically, when I run the CPUID Hardware Monitor, it reports these
voltages:
[image: Inline image 1]
The numbers for -12V concern me. :-) The columns are Current/Min/Max,
respectively. So if you have a power supply that's taking up space that
you'd like to reclaim, please let me know and bring it to the next MUUG
meeting.
As it happens, I'll be bringing some valuable (I hope) hardware items to
the meeting as free …
[View More]giveaways. I sure hope there are some takers!
Kevin
P.S. If the image inserted above doesn't show up due to filtering en route,
the -12V reading is around -6.21V. I'm using the system as we speak, so I
guess the -12V line doesn't do much that I regularly rely on, though I have
experienced some system oddness lately which may well be explained by this.

My main box has 8GB RAM. There's usually 3GB of programs running. The
rest usually is shown as free or going to buffers/cache.
I have a set of files I often linearly scan through and they are around
1GB. They used to read in and stay cached for hours (I can tell
because my scan takes 3s when cached and 90s when not!). Now they seem
to get dropped and require re-reading all the time, like if I don't use
them for a few minutes.
AFAICT my ps load has not changed and I'm not doing anything …
[View More]that is
requiring more cache/buffers that is pushing them out.
This seems to have started when I upgraded my kernel from 3.4 to 3.6
(Fedora 16) though I can't be sure at this point.
Does anyone know of some tunables I can try to tell the kernel to be
more likely to cache for longer? I'd rather cache at the expense of
pushing more programs to swap (I run a zillion programs at all times
and never close them).
I have played with /proc/sys/vm/swappiness (80 has been great for me in
the past) but a) it doesn't seem to affect my problem now, and b) the
docs leave me scratching my head about how it really affects file
caching.
At this point I'm not interested in solutions that are "rethink your
scan!" as I do plan to one day database-itize and index the 1GB data
set... but not today!

Anyone have a socket 775 motherboard I could borrow to troubleshoot a
problem.... and possibly buy, if mine turns out dead?

One thing you can *sometimes* do is write the smaller image to the card, then use gPartEd (or similar) to increase it.

I have a rarely-on (media player) linux box that since the daylight
savings changeover (I think) always boots with the time off by 1 hour.
(I think it thinks it's 1 hour later than it really is.)
It's a modern(ish) Fedora 16 with the latest updates. I can set the
clock correctly manually or with ntpdate and all is fine until reboot.
Then it's wrong again. I am running ntpd on it to set the clock using
my own internal ntpd server that does keep correct time. I did check
that the timezone was …
[View More]set to Americas/Winnipeg and the daylight savings
stuff all looks correct. I use "system clock is set to GMT".
Such a silly problem, and I'm stumped!

Hi,
Any easy way to resize a bootable image for SD card? There are ready Linux
images for booting on Android devices, like MK802. The problem is, 1)
sometimes you don't have a card for that size (say 4Gb image, 8Gb card) or
2) micro-SD card come in random sizes, so an image for 8Gb card can be
some kbytes too long for a 8Gb card of another vendor.
I probably could mount the image, copy the contents and go over the
process of creating a bootable image myself. But is there a way of doing
it …
[View More]with a lesser effort?
