Wiggo and Bill G must use some secret Voodoo magic or maybe they are wizards who can some arcane AP magic spells. The thread could be renamed The Wiggo and Bill G AP Thread. Although they do seem to leave an odd crumb for some wondering chap to find.

Looks like I am keeping with a theme here. A day late and a dollar short..lol

Hard to believe it has been 19 years since I first tried to catch an alien signal. Gone through a BUNCH of computers, software and checking on the forums to see what is happening. I have taken a break here and there but always drawn back to this community. Seti@home has some of the most knowledgeable and friendly people you couple find in a forum community. Sure there is the odd tussle but just enough to add to the entertainment.

Here is hoping we make some real progress in the next few years and create our own = real WOW event =

Thanx for the ride all, everyone here helps in some way.

Daily quota is not the same as the cache size limit. If they were the same then all the top 20 (or maybe top 1000?) crunchers would struggle to get work.

Thanx for the clarification Bob. I thought it was set a long time ago. Protecting the server with a one size fits all method isn't probably the best option as viewed in hindsight.

The part most are missing I think is this.

. I do get unlimited quota between 1AM and 5AM and I've set the scheduler to download/upload during that time only.


So if he had a way to Download more WU's during this time it would not cut into his monthly quota. Ageless idea seems to be the most responsible answer and would work if he wants to run other projects. I have seen suggestions in other threads of have more than I instance of BOINC although that may not work as he wants, I assume it would mean he would have to run 2 accounts (or would making it look like 2 computers be viable). The other issue how to do schedule DLs/ULs with 2 instances while sleeping.

Just a thought, I have never has this issue but it is intriguing and there must be a way around this archaic limit of 100 units that worked well 10 years ago but not today.

I see a lot of people use notepad to edited files and for the most part it works but has a few easy pitfalls, its very easy to save to the wrong file and it has no syntax checking just for starters.

I use Atom Editor to change any files needed for BOINC. It has format, syntax ad spell checking to help you see errors easier. It's free and there a TON of videos and web pages out there to help you make Atom work for you.

https://atom.io/ Atom Site
https://en.wikipedia.org/wiki/Atom_(text_editor) Atom Wiki

I think there a couple other free editors out there that may be as good but I haven't used them. I just know Atom works much better than a word type text editor. If this has been mentioned before than sorry for the spam.

Post:
Here is another

------------------------------------> DEAD HORSE <------------------------------------------------

that just can't be beat any further.

Using straight deadlines doesn't work at all due to all the different deadlines projects put on them. If they just used deadlines then only the projects with the shortest deadlines would ever get processed, WU's from Seti would never get worked on. I am not totally sure on how BOINC decides what WU to do next even though it has been posted on lots of different forums, Part of the formula uses FIFO i know it mixes Resource share and if a WU is about to expire. The rest is magic cast by a witch docter I suspect.

I hope that helps a little bit.

Speed of Voyager 2 = 56,000 km/h /35,000 miles per hour (9.7 miles per second)

Speed of light 186,000 Miles per second

V1 186.000/10.8 = 17,222 Times as slow

V2 186.000/9.7 = 19,175 Times as slow

Even if we rounded up to 20,000 times as slow X 4 years that is a total of 80,000 years. Still a VERY VERY long time but much shorter than 280,000 years,

If I got something wrong here please correct me.

11) Message boards : Number crunching : How to manage backup projects. (Message 1926024)
Posted 23 Mar 2018 by Profile Cactus Bob
Post:

Just change your backup project resource share to 0 (zero).
By doing that you will allow your host receive work from that project 1 WU at a time when Seti is down or has no new work.


That would work if I just wanted the other projects strictly as backup, I think maybe I didn't ask the question properly.
I have the following resource shares for my projects using GPU only.
Seti ---------- 300 (37.6%)
Milkyway --- 96 (15.2%)
Einstein ----- 34 (5.4%)
I also have POGS with a resource share but it runs on CPU only and is the only project that uses the CPU

I think what I am really asking is there a way to have my downloads reflect resource share?

The Zero solution is viable if there isn't a better one.

Thank you
Bob

I know i have seen some posts on this but after searching a lot I have had limited success to finding the best approach to the following:

I only use 1 computer and it is not a dedicated cruncher, it will do WUs for 2 to 6 hours a day depending on my usage and when I go to bed as I turn off the computer when I sleep.

Seti@home is my Main Project
Milkyway@home is my 1st Backup Project
Einstein @home is my 2nd Backup Project.

I would like to have 2 days worth of WU's for Seti and a half day WU's for the backup projects, Ideally Milkyway would have more than Einstein. After many attempts right now Milkyway has the most WU's followed by Einstein then with Seti having far fewer than the 2 backups.

You can not set computing preferences for each project as the last one edited will propagate to the other projects to keep them all the same. I tried setting my Seti settings to the home computer and the other projects to the default location and while that looks like it should work I am not getting the results I hoped for. Short of managing the amount of WU's I get by using NNT is there a way to have BOINC manage each project differently.

I know some you crunchers with high RACs have to manage backup projects as you run out of WUs during scheduled maintenance.

Thank you

Zalster, your link does little to explain why the double blc at the start. Would there be a reason for that? I am assuming the DIAG means diagnostic but maybe not.

There are 7 of these blocks of work units I noticed on the SSP that have - blc02 - twice on them and - DIAG - in the middle of the file name.

blc02_2bit_blc02_guppi_58157_16456_DIAG_PSR_J1024-0719_0006

another one just has the - blc02 - tag just once

blc02_2bit_guppi_58185_56386_DIAG_PSR_J2022+5154_000

Those of you who understand how these names work maybe cam enlighten us if there is anything special about them. I assume diag means diagnostic but that is as far as I can go.

Post:
What I suspected. At this time we would only detect a high energy signal that was sent in our direction or close to it even with sun that are close to us.

I am not saying what we are doing is not worth while. There is a small chance to catch or detect a directed signal. The other important aspect of this project is that we need to find out what works in order to know what will work. Most successes are built on many attempts. Some attempts will have more success that others of course.

I think we have a ways to go before we can say we hit our Kitty Hawk moment and even have done a short flight. Extremely difficult to know what may work when you only have a sample size of one.

This thread and Seti@home is not about communicating, I completely agree with you that is would very doable even without using 2 huge dishes on both ends. Right now SETI is all about detecting, I assume communication with any alien source would go to some other project.

Lets get back to the topic at hand, Do we leak enough signal and strength to create persistent and delectable chirps 4 LY away with the equipment and software we are using. You mentioned
but this all just maths and physics

and if the signal acts like gravity and fades the square of the distance, will it still be delectable at that distance?

We are trying to detect some signal or communication from a alien source without having much of an idea of how they would communicate. A sample size of one does not help us a lot in knowing how communication develops with civilizations. Questioning methodology is a good way to help develop it.

I know this has been discussed before but I would like to refine this a bit more.

Let make a few assumptions.

Lets assume there is a planet that orbits one of closest stars (Aplha Centauri) and that the aliens that inhabit it call the planet AC, they think it is a cool name. We will need to make a few more assumptions for the sake of this question. One is they are at the exact same advancement in science and tech as we are and not only that they have a program also that is looking for alien signals in the exact manner as Seti@home is. Of course most of you know where this is heading but I am going to finish it anyways.

Would they be able to detect us? If they also have been sending radio noise out into space for 70 plus years, could we detect them? I know we are looking for consistent chirping. would our signals be strong enough to pick them up or would one of us have to direct a strong signal and broadcast it towards them with the hope that they would then detect it?

Other comments or additional questions that keep to the topic are encouraged. There is always the thought in the back of ones mind that wonders if we are searching in the best manner.

Thank you

Gordon

Most programs do a very poor job of uninstalling themselves. I mean really poor. Most will leave data files, registry imprints and a ton of other stuff that can make an uninstall/reinstall a complete waste of time. A couple solutions, 1 is to manually search for all traces of the program and remove/delete them. Doing a search with explorer works although it can very tedious and time consuming. There are a couple of decent uninstall programs that will do most of this for you, I had to find one of them to fix a problem similar to this on my brothers, I may have used IOBit Uninstaller but a simple google search for them and then another to check how good the uninstaller is what I recommend.

You may have installed this program differently then your other two so it may not reside where the default would have put it. Without a complete uninstall your just beating your head against a wall. A DOS work around would probably be 10Xs the work but that is just a guess on my part.

Of course your very last option is a complete wipe and reinstall of the OS and all contents. That may be a touch extreme but it usually works. Of course YMMV is always the mantra when giving this kind of advice.

Good luck and may the force be with you.
Bob
