ipmi regression in 4.5?
I've been monitoring CPU temperature on a few Dell SC1435s running CentOS4
via OpenIPMI and 'ipmitool sdr'. It's been working very nicely, but the
upgrade to 4.5 not so long ago seems to have broken something:
# ipmitool sdr type Temperature
Temp | 01h | ns | 3.1 | Disabled
Planar Temp | 04h | ok | 7.1 | 30 degrees C
Temp Interface | 53h | ns | 7.1

Anyone using GQRX in Centos-7, for SDR ?
I gave myself a toy, one of those cheap USB Software Define Radios, and
would like to use it on my C7 box. Having wasted some time on it, I gave
up and installed Ubuntu on a USB HD so I can boot that to play with SDR.
The Ubuntu GQRX installation is well documented and went off without a hitch.
but I just hate having to boot something else on my main box (partly because
it also runs a mailserver

Is it a Realtek chipset?
I've had problems with it on CentOS as the system will load up the DVB drivers (for TV tuner) thus interfering with the SDR.
What worked for me is blacklisting them & reboot. Give it a try.

I wouldn't want to use SDR as a simple time source.... SDR uses a /lot/
of CPU to make up for the lack of radio hardware. It would make far
more sense to get a dedicated WWV or GPS reciever to use as a time
reference, unless you're going to dedicate a server just to be a
software radio.

odd issue with ipmitool
Got an older server running 6.5. I've been fighting it - I have two
webcams for surveillance of the room; one works with motion, but it
resizes the picture down
Adjusting resolution from 640x480 to 360x296
and the video's dark and bad contrast. So I went back to the camer I'd
been using before that worked fine... on CentOS 5.x, and then I remembered
why I'd gone to the other camera

C API: How to get a seektable for very long files?
Another SDR user here. It was me who reported the bug where total samples
wraps around on overflow.
FLAC performs extremely well on SDR samples, both speed and compression
ratio. In my testing it outperforms any other free lossless codec by a
large margin, being 20% smaller and 10% faster than the next best (which
was ffv1). The problem is the metadata, and not just total samples. We also

IPMI and Dell ERA/O
Hi Everyone,
I have a dell 1750 server with ERA/O card running on FreeBSD 7.0-STABLE
According to Dell, the ERA card supports ipmi 1.0:

But so far no luck with freebsd :/

has_many - when are child objects created?
I has several model objects that flow down like a tree:
Class1 has_many Class2
Class2 has_many Class3
and so on.
when are the child records actually created?
If I do:
c1 = Class1.find(:all)
are the child objects (C2s below) created then or not until i do something like:
c2s = c1.C2s while iterating through the c1s?
If the form, that''s cool, no problem, but If I''ve got

Anyone using ffmpeg as a source-client?
I'm just wondering if ffmpeg is a reliable Icecast source-client -- a
"pusher" to send a stream to an Icecast server and runs 24/7/365 dependably.

That's a bug in the flac application. I think the correct behavior is

question about --emit-relocs with lld
Hi,
While doing Linux kernel builds linked with lld, I've tracked down a
difference that breaks relocation of the kernel image (e.g. under
KASLR[1]). Some relocations are changed to ABS (weirdly, all are in
.rodata section). Note the difference below in the resulting linked
output.
.L__const._start.instance becomes *ABS* only under lld:
$ cat minimal.c
struct minimal {

This could be completely ignored by regular audio players - these files are not meant to be listened to anyway. I could probably figure out how to implement that, I even started looking into it once, but

System Time Source
One of our STEM interns recently observed that there are
inexpensive clocks that sync via radio to standard time
services.? This begged a question about why every computer
would not have a radio module to receive time.? Our senior
staff did not have a good answer or if time from such a
radio module would be supported by the operating system.
When I was a student, such questions would have earned

C API: How to get a seektable for very long files?
I am not an SDR user, but I think it would be a great idea to design and register an application metadata block for FLAC that supports these needs.
The fields in this application-specific metadata block could document how many files there are in total; which file in the sequence the current file is; what the actual sample rate is; how many bits in each sample are valid (to a finer degree than

Multipathing with Sun 7310
Dear list,
we have a relatively new Sun Storage 7310, where we connect CentOS 5.5
Servers (IBM LS21/LS41 Blades) via Brocade Switches, 4GBit FC. The Blades
boot from SAN via qla2xxx, and have no harddisks at all. We want them to
use multipathing from the very beginning, so /boot and / are already seen
by multipathd. Problem is, that the Sun 7310 has two storage heads which
run in
