In Syd's post #807 he mentioned some things are not done yet.
Code:
-Detecting merges in sequences, sequence overview

It seems that this doesn't work for aliquot sequences. Example: the additional information for the c170 cofactor of the latest step of aliquot sequence 4788 reads:

"Is factor of
2505014548...<171> "

I think it is supposed to give some more information, like "is a cofactor of aliquot sequence 4788, line 2549"?

BTW: The old DB seems to be down, I only get an empty page. Is this on purpose?

BTW2: will there be a possibility to report ECM curves and p+/-1 runs in the new DB - to keep track of ECM work done?

 2010-09-13, 00:43 #851 RichD     Sep 2008 Kansas 23·34·5 Posts It appears the new data base has been cut-over live. What does "Do quick self-test" at the bottom of the Status page do, or is that only for internal checking? I also noticed that Login is not done yet. But still a great piece of work......

Yes I'm working on it. First I'll have to store the sequences in another format that can also detect merges, the overview can be read directly from it.

Perhaps I will just suspend intermediate submissions for now and simply add .elfs to the sub-forum posts if the issue hasn't been resolved by the completion of the sequences. Thanks. . .
I hope you haven't modified it yet. I just moved the new database to the root directory, http://factordb.com/, http://factordb.com/new is no longer reachable. The old database is still online on http://old.factordb.com/, but I'll take this off in a few weeks.

It should, thats the same issue as with the merges. I'll fix this afterwards.

The purpose was a memory & upgrade

Yes there will be. Maybe already tomorrow.

The old URL for submitting factors should work again, the search.php-script now redirects to the result.php-script.
I tried to make the old url für .elf-download also work, at least for aliquot sequences it does, i hope.

No you didnt crash anything. I use transactions, so the worst you can cause is a rollback.

Does it now show up everywhere?

Some more changes:
+ (quite simple) factor tables
+ Added odd/even filters to variables (Thanks to kar_bon for that)
+ a bunch of small bugfixes

 2010-09-13, 03:23 #854 WraithX     Mar 2006 23×59 Posts Hello Syd, Thank you very much for continuing to maintain this excellent resource. I've noticed on the Mersenne Factor Table page [took a moment to find ;) ] that when you click on "Next Page", it skips you forward by 500 and not by "Results per page" (rpp). So with the default rpp of 20, you start out seeing 1-20, then click next, and see 501-520. Can you change this? Also, I'm not sure all the factors have been moved over from the old database to the new one. For example, if you look at 2^5105-1 in the old db it shows up as FF, in the new db it shows up as CF. Another thing I was wondering, do you have plans to accept primo certificates? I have quite a few for prp's from the old db and would like to turn them in. I think verifying certificates is supposed to be a fast process, but I'm not sure how easy it would be to tie it in with your db. I might be able to write a command line verifier, if you're interested. Or, if you like, you could write one, the pseudo-code/algorithm is provided when you download Primo. If you'd like me to write it, can you compile GMP programs? I can write one in GMP and send you the code. Let me know what you think about this.
 2010-09-13, 16:47 #855 rekcahx   Oct 2009 Oulu, Finland 2·3·5 Posts Syd, thank you for improvements of the DB. There is some minor, non mathematical cases, i.e. nested a-tags. It is slightly hard to parse. http://factordb.com/listtype.php?t=3&start=99700 Could you consire to use css and classes instead of font tags? I wish also that there is pure text format for unfactored composites, i.e. http://factordb.com/index.php?id=110...0212700279&raw will produce 29368311107434164767966060318936186968928546806215540019457744157070060 without any html or newlines. If so, It is easy to use in automatic factoring process.

I once made this page for me to check if everything is working correctly. If anyone else wants to do the check - now you can

Thank you! Can you please check back on this bug? I can't reproduce it.

Yes some are still missing. I'll try another export with higher depth, maybe this time I'll get em all.

No I had no plans regarding primo certificates, but its a great idea! As a command line tool its easy to write a plugin for the db, for example - pass the certificate via STDIN and get back the result as return code. But thats flexible - could be from a file or something.
Would be great if you could write something like that - libgmp is installed (5.0.1 and 4.3.2)

 2010-09-14, 01:16 #857 warut   Dec 2009 89 Posts A bug If you factorize x!+1 with FF unchecked, you still get 3 FF entries (x = 4, 5, 7).

Ah, I see that it happened when I turned off P, PRP, FF, and CF (I just wanted to see composite with no known factors [C]). I see that it is trying to show 20 results per page, but since there were no hits in the first 500 n, it gives a blank page, and clicking next starts at n=501. I thought unchecking those boxes would just show results from the first 20 n, and not the first 20 results from within 500 n. (if that made sense) Maybe there is a way to separate these two cases? Maybe a radio button for 20 n per page, or 20 results per page?

OK, I'll start writing one, and I'll see how fast verification is on some of the certificates I have. I'll let you know when I've made some progress.
