That is, until their state is observed :)

Ah, I see what you did there. :)

Let's just hope that we observe at that propitious moment at which all probabilities collapse into the states we wish for.

Be careful what you wish for, you might just get it.

Now that there seems to be more capacity available, here is my wish list:

Daily graphs now produced by different mersenne sites from partially copies of the server data. See mersenne.info and mersenne.ca.

1. percentage of exponents
factored by range of 100.000 and 1.000.000
Double checked, first time LL
2. How deep factored for trial factoring, PM1, ECM.
3. Server stats like participants, pc's, cores, speeds, etc.

And preferably retroactively for the entire v4 and v5 period.

just asking.

So, I didn't exactly say my changes were live, but they did go live a couple nights ago:
http://www.mersenne.org/assignments/

Any thoughts? It has the "hover on account name to show the computer name", and just for fun I added in a "sticky header" on the table so it stays at the top when you're scrolling down a long list of results.

It should be fitting well onto the page now that the one CPU Name info is gone from the list.

I can still add an XML option to that, but since this whole page was previously hidden, and it is limited to 1000 rows for any particular range, before doing that I thought I'd see if anyone is actually taking this data, scraping it, and doing "something" with it. Otherwise I can backburner that and focus on adding that same XML kind of option to other pages first, pages where I know people are scraping stuff already and would benefit from a better output option.

EDIT: Just a funny side note, I *love* the optimism on display with some of the super-high exponents going through LL checks by different people. I mean, we're talking expected completion dates in the year 2072 for example. Now that's taking the long view.

I'm tempted to assign myself the highest exponent in the list and just start plugging away at it. I'm inspired. :) It might not complete until the universe achieves 0 degrees Kelvin. But then again, I think my Q-bit computer is in the mail which will finish it up during my lunch hour.

It's worth taking a look at. Up until now I've just redesigned existing pages and added a few new bells and whistles. Some of those could be extended to include things that would be nice to have, or give some options to toggle exactly what gets returned.

If there was a need for some brand new report page because nothing exists currently that really lent itself to that, I don't know PHP much at all, but I could probably ~~steal~~ borrow enough from one of the existing pages and then hit up James for anything that truly baffles me.

For the most part, any magic would come from a well constructed SQL query. I've seen some major parts of the data structure but I'm not totally sure about the relationships of different tables.

Come to think of it, if there are any useful data sets you see over on mersenne.ca or mersenne.info, could you point me in that direction? I'll be honest, I haven't poked around on there too much. I'm sure if I did I'd find all kinds of cool ideas. I'm just now, for the very first time, looking at some of those that James has and they are pretty nifty.

I don't know if there's any super benefit to putting similar or the same graphs/tables on mersenne.org directly. I assume it's pulling from the same raw data and they don't have any other sources of info, but maybe? Like data on exponents above 1E9?

My problem is, I don't really know what's "interesting" to people.

One of my "real" jobs is to create SQL reports for some folks on our team, and although we have lots and lots of data, until I start to gather some input from them about the kinds of reports they like, I tend to create one-off reports at first. If they start requesting the same things over and over or different people are asking for the same stuff as well, that's when I create a report out of it so they can run it whenever they want.

There's a lot of other people who have really taken to the whole prime finding thing with a passion and yeah, I just can't predict what they would find fascinating in the data, but if you have some ideas, send 'em my way and at the very least I can spit out some ad-hoc queries to pull that data and at the same time educate myself on the data structure.

That is, as long as George doesn't mind sharing some particular set of data... it would have to comply with the privacy and legal requirements of course, but if I'm reading George's intent right, he's all for sharing data on the exponents and progress on assignments. I just don't want to promise some reports that I couldn't deliver so I'll only say that I'll consider any request.

This was James' cool idea.

You can shortcut straight to the exponent detail page of any M_N by going to (example):
http://www.mersenne.org/M13

Example #2:
http://www.mersenne.org/M45271279

It just redirects you to the full report page for that exponent, but it's a handy shortcut.

We added that a couple weeks ago and I just remembered it.

Make a to that link on all the report pages that list exponents.

Those graphs are fairly intense to generate, not so much rendering the image but pulling the data. While not absolutely necessary to archive the data values for each day, I do, and it amounts to about 325000 records every day. I do archive them yearly and prune off 120-million records for the past calendar year, but yes, it does add up to a whole lot of data. My data should be reasonably close to accurately duplicating mersenne.org data (I need to get around to writing a few more export reports and import spiders to be 100% in sync), at least plenty close enough for the purpose of the graphs. I'm not sure that putting that load on mersenne.org would serve any real benefit. You're free to link to the graphs or even copy the images to mersenne.org every morning if you wish.

And yes, as far as I know mersenne.ca is the most complete source for data on exponents between 10⁹ - 2³². There are a few projects like Operation Billion Digits that were working above 1000M before I started tracking those exponents, but I'm not even sure if OBD is still active. I included all previously-known factors I could find when I started tracking >1000M (and found another ~70-million since

).

I find the Trial Factored Depth summaries from mersenne.info useful, but odd that the information is not always up to date and only updated on a 24 hour cycle using a selective scrape, which seems quite cumbersome.
But would Chis be upset if you borrowed some of that?
