So the pond I dug looks a bit more like muddy water, ina natural
way. I'm not so convinced after years the wter is good to drin for
cats and birds, but they seem to like it.
A new computer ?!
No way! At least, not really, it's the same motherboard and I7 chip,
the enclosure from like 2000 or so, and the same "green caviar" WD
hard drive, but it runs Fedor 17/64bit now, has a new "platimum
energy grade" KiNg Flower 550Watt power supply now, a new Zahlman
CPU cooler, and a new Asus GT640 "Kepler" graphics card.
Also, I added two Sharkoon ultra quiet 12cm fans to keep the machine
pretty cool. The better than 90% at low loads efficient supply unit
(from a German supplier) operates fanless, unless it would get
really hot, so normally, also under load, the big fan never turns at
all. Because of the extreme efficiency of the supply, the whole
machine draws under 80 watt in normal rest operation, with the
graphics card active. Maximum power should be about 130 W for the
I7, and 75 W for the graphics card, and them the mother board, peak
use for disc and usb, etc, which remains way under the 650W max for
The whole works good, as the "new" 24/7 webserver, HD TV, vcr, web
browse machine, video/audio encoder, audio processor, etc. In rest
the graphics card remains 35 degrees C, the CPU somthing like 42,
the mobo and hard rive about 35, so it should work good. The old CPU
fan was the original Intel "copper core" one, the Zahlman has more
mother board cooling associated with it, and has heatpipes, so it
cools well, even though the fan might be a bit slow at 1500 RPM max
(compared 2000+ RPM for the original under huge load). Thus far the
temp remains under 63 degrees, but maybe the bigger loads require
extra fan speed.
The Zotac graphics card I had in this machine from when I built it
broke down, and was taken back by the manufacturer. 24/7 with peak
temperatures of 60/70 degrees C was the limit for it, which I didn't
like. But I got a refund, and the GT640 Nvidia/Asus card is quiet,
and can cool very well so I can use huge VDPAU video smoothing
filters, which is great for TV and High Definition sat movies.
Cuda doesn't work yet because thecompiler version of Fedora 17 is
too new for the Cuda 5 download I tried...
This fan can almost not be heard:
I did see sparks once, though:
The connector wasn't isolated and touched the frame, ough. Maybe
because it is a modular supply i didn't have any errors, everything
kept working fine.
The i7 notebook Iuse received a 15 euro new fan coming all the way
It's not exactly the same as theold one, and maybe not as quiet as
it was at first, but it works, and i've got the old one as a spare.
All the screws went back in place nicely, it appears a decent
design, this Asus.
High Definition Satellite
The ITV1-HD (the explicit HD one) at night broadcasts movies which
arn't much processed anymore, so that the quality has vastly
improved, which I'm very glad about.
Click on these images for the full resolution screen dumps, which
look eally cool. I didn't process these screendups they're really
"live" from sat TV, but I did adjust the VDPAU video
accelerator to filter in mode 4 (temporal and spatial filtering)
quite a bit. And dithereing is on. The card doesn't get much hot, 50
degrees celcius with fan speed of 10 to 15 percent, but power use of
the machine is up from under 80 Watt to about 150W.
I'm glad the machine holds up fine with these high definition
materials woring great on one screen with other applications.
"Life's higher values"
I saw Woody Allen's "Midnight in Paris" and Polanski's
"Carnage" inthis theatre:
Well, drinks, it goes in the Kenwood blender.
I liked looking up sites in San Francisco on Google maps:
Looks like a nice place to live.

Still more CD correction signal processing
I've added a 44.1 k Samples/sec domain to the 192kS/s sampling
domain, to do more CD sound corrections. This appears to work,
though it cannot all run on one machine at the moment, and not
everyting there is to correct is yet corrected.
Not bad for phone cam.
