Is there a reason that the "show digits" page has a line break after every 120 digits?

view-source:http://factordb.com/index.php?showid...00000744999917

Let the browser take care of wrapping please. That makes it difficult or impossible to either copy to clipboard or parse.

That's true.

I can also add a constructive solution. Borrow the solution from Kamada: he inserts soft break symbols after each 10 or 20 digits, so that browser arranges long, very long and even very-very-very long lines quite fine and this doesn't interfere with copy pasting!

Example: http://stdkmd.com/nrr/repunit/tm.cgi?p=20
Here is the snippet of the HTML code (remove spaces in & shy;)

Code:

Except on my computer, using Firefox, that "shy;" apparently gets rendered as a hyphen character during word-wrap. I see word-wrapped numbers having a hyphen in the middle, and the copy-paste shows it too:

Code:

(number with no word wrap [and no hyphen] in the mersenneforum compose window, ie: all "& shy;" removed)
41178786268652727777818909308744042083055383859495037243190192388737567013766369770914385034350354193614379285959651069848809053<128>

(number with a single word wrap [and a single visible hyphen] in the mersenneforum compose window, ie: all "& shy;" in place)
41178786268652727777818909308744042083055383859495037243190192388737567013766369770914385034350354193614379285959651069848809053<128>

(html of number from Kamada's page)

And... strange, a single hyphen shows up in the mersenneforum text-box compose-message window (at the word-wrap point), but it does not show up in the message that is rendered/posted to the forum. Also, each "& shy;" is rendered as a hyphen when I copy-paste into my text editor. This solution doesn't seem to work on my system.

Yeah, indeed, it is not perfect either. I remembered that it worked (I think) on his old site.
He also has some hidden java code that can compute the very long values which are initially hidden for brevity but expand if you click on them; there are some interesting ideas in the design of his site.

It's up for me, and my scripts (different location/ISP than me currently) haven't reported any problems.

http://downforeveryoneorjustme.com/factordb.com <-- also seems to be up from them

chris2be8 · 2015-04-28, 15:57

It came back up shortly after I posted. It was certainly down though.

My script runs every half hour and didn't report anything amiss

rob147147 · 2015-04-28, 17:53

It was just intermittent timeouts for some reason. I'd just cleared everything up to C92's, and happened to be watching when someone dumped about 2,000 small composites C65-C75 in the database and my workers struggled to grab them from the server.

chris2be8 · 2015-04-29, 16:42

Taking another look at the traceroutes I ran it was probably a network issue affecting the last few hops before factordb.com. So it may not have affected people connecting from different parts of the world.

2^490*490##+1 aka 3511#*2^490+1 (http://www.factordb.com/index.php?id...00000777746256)

I do N-1 proof, and apparently PFGW's definition of ## is different from factordb's, so it is tagged as composite.
