Even some the digital cameras (that are on the market) have that function for long exposures noise cancelation. It is usually called dark-frame substraction or long time noise reduction.

Ah, OK, I was worried about that.
Thanks.

Is the receiver Alpha on Arecibo out of commission? From the stats, looks like last time that we got data from it was some 210 days ago.
Is the science behind this project just recycling old data?

Just don't shoot the compressed air into free spinning blades - the resulting rpm's can be high enough to damage the bearings.

I did have a GT8800 die because of constant overheating - lifetime replacement gave me a GTS250 that now I don't use for crunching anymore.

Even the modest ones can give some satisfacton :) After you grease that cheap sleeve bearings on the fan. As you see, is mandatory to have 512MB memory.

IV. No, I won't buy ATI anymore. I was using exclusive ATI till I realised that nVidia has a more user oriented policy with CUDA/Physics. I did the switch to nVidia and I have no reasons to switch back. ATI is doing this just because was forced by nVidia, not because they belive in it...

Narrow band signals have the ability to travel farther and are easy to discern from the background noise.
Wide band signals are used more when you need a higher density (and low power) of users like in our phone systems. CDMA uses something like that. Military spread-spectrum uses something like that.
Those evolved transmissions will look like noise anyway to our software, I don't think we have the capability to find ET thru that. AP it is not looking for ET in my opinion.
I really think that something else it is going on here...

Back to the subject:
I think the Astropulse WU are "pushed" in front because... they don't care to much about seti original ideea - finding ET, but more about the distribuited computing and finding other usefull (in their wiev) uses for the computer base.

Well, I won't do anymore AP WU, I have started to give time to seti for the original ideea and I stick to that. Sorry...

Intel Atom procesors are NOT doing code out-of-order like the other processors since Pentium. So, it looks like it is a great deal, but actually is not that good today, when almost all the software it is optimized for out-of-order code execution. Performance is below a dual core Celeron.
And, yes it is avail only on a combo with an Intel MoBo. For now.

[quote]I am using successfully UltraVNC - it has a client/server for Vista x64, works as a service (I can reset the PC and I can type in the logon password if I need to).


I'm also using UltraVNC on my Vista HP 64 system, but I have one issue - when I get the pop-up "admin" prompts (like when starting services) I get booted and can't get back in, have to walk over to the PC and click the continue. Anyone know a way to fix that?

I forgot to tell you to check on the server to disable the AERO interface when you are connecting with the client...
14) Message boards : Number crunching : SETI mentioned on nVidia CUDA page now (Message 880744)
Posted 30 Mar 2009 by Profile SoNic
True, that statement is vague enough that it could be eventually true. Like pinning the cheapest CPU against the most expensive CUDA card.
But that kind of verbage it is characteristic usually for deceiving marketing. It is sad that an scientific endeavour got mixed-up in such advertising.
Why? Because some of the new commers might feel that where scammed or someting and a negative effect of this will affect Seti credibility as a whole.
I guess it was a part of the deal... I don't know.

And it doesn't matter to much when "no work is available for SETI@home Enhanced"...

Unfortunately they are using the same 10x marketing scam... There is no 10x speed up, more like another core added when we are comparing equal amounts of money spend.

I am using the x64 version that it is beta-RC1. As I said I can reboot the machine and type in the password if I need to.
Ah, use the MSRC4 plugin (the other one didn't work for me) and also I had to install manually the supplemental video driver for Vista (Add/Remove Hardware...) - it works faster with it.

18) Message boards : Number crunching : Astropulse Errors II-Optimized version 5.03! (Message 876842)
Posted 18 Mar 2009 by Profile SoNic
Have you looked at your app_info file

If you used the one that came with the download, you will only get 5.03 wu's. You need to merge it with your existing app_info file so that you continue to get MB units as well as astropulse.
There are plenty of people more qualified than me who can help you with that..


It's not about app_info. It is about the fact that when I tick the option to receive AP 5.03, I am receiving ONLY those units on ALL my computers. When I tick that option off I am receiving MB and occasionally AP 5.0 WU.
It is about the way the servers assign WU's - there are "biased" towards sending AP 5.03.

I cannot process this kind of units because every time that I select in options to process them, I do receive ONLY this kind of units, rendering useless my GPU/CUDA.
A change in the policy is needed to prevent hogging of the Boinc by those units. If you want to process this kind of units, leave the original SETI units to live too...

I have just installed Vista x64 and V10 x64 apps (C2D with GF9500, 4GB). I don't get any more WU's...
The last messages of Boinc manager (latest version) are:
Fetching scheduler list
Master file download succeded

LE: Installed ver 10b and all's good. For now. Thanks.
Dang it, I got only AP v5.03 now... no nice CUDA for me I guess...
