The repairscript just finished its work, looks like the bugs are fixed.

[QUOTE=Syd;233970]The repairscript just finished its work, looks like the bugs are fixed.[/QUOTE]Thanks for the repair.

I've been relying on the DB to keep up to date on the Aliquot project and appreciate all the hard work you've put in to maintaining the DB. Thanks!

Sounds a little low....[URL="http://www.outerstats.com/site/factordb.com"]$69.00[/URL] (USD, I assume...)

This analysis sucks. I tried it for some sites, and all results were absolute wrong.

Should the "Proving probable primes <1000 digits" worker be bumped to a higher limit?

[QUOTE=RichD;234649]Should the "Proving probable primes <1000 digits" worker be bumped to a higher limit?[/QUOTE]

It seems to be pretty busy as it is, even with the help of the " Proving probable primes <=200 digits" worker.

I guess Syd is the only one with enough insight into the workload to prioritize well.

More workers would be awesome, obv. Perhaps one factoring numbers below a limit between 70 and 1k digits. And one checking the status of numbers below a limit between 1k and 10k digits.

Raising the limit on the factoring worker seems to have been a success.

Anyway, really diggin' this DB.

Something wrong with [URL]http://factorization.ath.cx/index.php?id=1000000000000038219[/URL]

What's wrong with it? If it's the red cofactor you're worried about, that just indicates that it is "status unknown"--i.e., it's sufficiently big that the DB hasn't (yet) gotten to it with a PRP test to determine whether it finishes the factorization or not.

The factorization is wrong, try in the FactoDB "(2^38219-1)/4381298797428052406300189129".

Hint: The sum of digits of the two cofactors is about 8 digits too small.

Edit: The correct small factor is 165056813708157873340366248563710409!

That's it.

Still there. Any idea why?

No. Only Syd can correct this error manually.
