Radioactive@Home ist aktuell auf einem VPS-Server (Virtueller private Server) gehostet.

Dieser Server ist nicht schnell und zuverlässig genug für die erwartete Anzahl Detektoren (bald über 300) und Datenmengen, wir müssen auf einen dedizierten Server umziehen.

Unglücklicherweise sind die Kosten für einen dedizierten Server zu groß, um sie aus unseren eigenen Mitteln zu bezahlen, wir würden daher gerne Hilfe von Euch in Form von Spenden bekommen.

Sobald möglich werden wir ein Spendenabzeichen für die Leute, die uns bei der Kostenübernahme geholfen haben, einführen.

Vielen Dank an die Leute, die uns bereits etwas gespendet haben, und an alle, die dies in Zukunft tun werden :)

Edith sagt übrigens:
Den Spendenknopf als solchen gibt es schon, auf der Hauptseite unter PayPal-Donations, nur das Abzeichen im Konto für die Spender, also das BOINC-Krönchen o.ä. fehlt noch.

How much money do you need? Are you going to buy a new server or rent from a hosting service? If you will rent then how much will the dedicated server cost per month?

I think if you explain the costs you will receive more donations. I can donate but first I need to know how much you need.

Also, my ISP is very generous and involved in community projects. If you want I can talk to them to see if they can donate bandwidth to your project since it is a non-profit community project. If they are willing to donate bandwidth then I can host data here on one of my Linux machines. I can give you whatever privileges you need to setup and administer the server yourself and provide dedicated RAID storage and daily backup to DVD.
____________

I can not believe that this project needs such high demands for the equipment.
65Euro is for many of the salary in my country. Maybe we should review them?

Process the data from the 3000 pieces of detectors is only 300 megabytes per hour.
It is much more a problem is to keep public data archive. But that's project of distributed computing. I think every participant Projects are not difficult to distinguish for example 10GB of space on your disk dimensionless. So you get a large-scale data storage without the risk of losing it. The server used only for the current task for a month.
____________

Oh. Well you have come up with a headache from scratch.
Too shy to ask - how much you know about radiation contamination / exposure?

What do you store raw data has no meaning. I'll try to explain.
We have. sensor installed in humans. Geiger is on the street (the house - it makes no sense).
sensor is connected to a computer and transmits data every 40 second measurements of the server. (if I understood correctly).
There is a notion - the relevance of the data. The question of how relevant the data on measurements of 40 seconds? Well, most people can point to the fact that "passed by a radioactive object", a word about anything. Other radioactive and techno-genetic accident gives a much longer background of countable hours or more. The minimum interval measurement in radiation reconnaissance accepted value of 30 minutes (if I remember correctly). Under no sense for a good reason.
Therefore, information on the map and in the base of the 40 second metering simply superfluous and irrelevant. So why such information is not stored. All you have nada to do an average of 30 minute interval and store the average value for these 30 minutes. Your base is reduced by 45 times smaller.
Anyway 40 seconds to measure the background gives a very large error (about 60%) for the SBM-20 counter (CTC-5), it is necessary to increase the time (or as I said average), and then the error will be approximately 20-30%.
And the graphics and data for people to become more clear and evident. You will then at least it is clear that they are for the "Saw" is shown?

What convinced you?
____________

My mother was a woman.

The mechanism of removal from the sensors (35 sec) changed inappropriately. I want to say that the loss of your base 45 times (instead of 1 GB to 22 Mb), the base will not lose relevance. In addition to store data that 60% are not authentic - why?
You only think about the figure - the information removed from the sensor by 60% INCORRECT.
As for the maps and graphics - to me a little that is clear. And the rest, too. Much clearer if the scale of the X will be the time. Hour mark, and half hour.
With regard to accidents involving radioactive material - it's about the collapse of HOURS and the level of contamination.
All I want to advise you - do your project is easy for people. Without loss of informativity and accuracy. But it will reduce your maintenance costs.
Well at least you read my posts. And I have a feeling that you do not want to listen to - hold opinions and to the point.

Tell me where am I wrong?
____________

More data give more statistical information, in some cases that is important (e.g. in calculating standard deviation).

Current database of results for only 60 detectors is bigger than 1GiB of data. This data are constantly updated and processed in system.

To save space and bandwidth on the server you could try to compress and distribute the raw data via some p2p network

Torrent is good that the archival materials can be placed in your home that provides low-cost content. Many companies today distribute any software through its P2P paid and free. So it's a good idea.

P.S. Here, for example - http://www.mikrotik.com/download.html
____________

Keeping 31 days of data in the database and providing the raw data in uncompressed format as described in this thread is unnecessary and it creates a huge demand for storage, database access time and bandwidth on the server. Why not clear the database daily and save the data in compressed files? People who want the data won't mind downloading compressed files. If you have a daily file for each continent (or region) it will allow users to choose only the data they want which would possibly decrease bandwidth.

I think FogBRD has raised some valid concerns and it sounds like he works in the nuclear industry or has some experience. You said you spent a lot of time discussing sample frequency but did you discuss that with radiation and contamination experts? I don't see any point in keeping more data than is necessary but you have said it allows people to calculate other parameters... what other useful parameters would people want to calculate?
____________

Indeed, what other data can be expected? I even became curious. Can you Show the world why you need to store redundant data does not have a scientific and practical value. That's just not talking about statistics. With regard to the SBM-20 is not justified. SBM-20 is not a proportional counter and can not provide the energy level of radiation as it makes a scintillation spectrometer. So we need time and level. Given its accuracy, and there are enough savings 5 minutes interval for the raw data and 30 minutes for the public on a map.
Here is an example of online dosimeter http://geiger.su/ click on the scale of 1h and look at the variations in time.

By the way Dagorath gave a good idea to do backups across regions.

I can the other - make a small wikipedia - we put things in order there soon (I hope users will be able to edit it).

The third idea - organize the formation of links to my point on the map.

And by the way is a link to the schedule of activities, many forums do not understand. It should be a link to the image rather than PHP that gives the picture. It would be a good advertisement for your signature on many forums and websites. As creators of a great public attention.

Speaking of birds - in many industrial dosimeters where there is a measurement of the background for further calculations, the length measurement of the background is from 5 to 30 minutes.
____________

I want to bring that to counter this rather average values ​​every 5 minutes.

User is in my profile indicates his country - enough to make the archive by country.

____________

You seem to want to enter additional data in the user settings?
What prevents this is done.
- The location of the sensor - the country
- The location of the sensor - inside / outside the house
- Mode of operation - continuous / periodic
- Type of Geiger sbm-20/sbm-19 ...

and so on.
____________

Storing data for regions sounds interesting, but need some programming work to find a way how coordinates join with regions (I will try to find it out).

Switching to another type of Geiger counter is simple. The closest is an inexpensive SBM-19. Having thus a better performance is comparable to the price of SBM-20. All other counters are much more expensive.
Mica counters to use this excess. Of course they will see and alpha radionuclides in the drop rain but it greatly increases the cost of the sensor.

for information - a modern analogue of the SBM-19 is the STS-6

I have 2 of your detectors so one would use the standard tube and stay connected to this project, the other would use the special tube and not be connected or be designated experimental.

Yes, there are many uses for the data and the decision what to do is yours. You will receive my support no matter what you decide. I was only making suggestions on how to save some money because the project does not have a lot of money. I won't pursue that topic any further.

Don't worry about delayed responses, your work and family come first. I am just happy you can find a little time to discuss and respond because so many project admins do not. Maybe they are too busy, no problem.

I am working on sorting and storing the data by region (country and possibly city or province) too.

____________

If you can compile from source code and program the controller is sufficient to change the formula calculation. Go tell that to measure the contamination of food is necessary to increase the time up to 5 - 30 min, after measuring the background for 30 minutes.
