Features request?

[LaurV]

Thanks James, meantime I clarified it by myself, as I edited my previous post to put the link to your page in the "notes", then I saw the "show source" button on your page (I am not using it very often). Looking into the source I saw the "$scaling" variable. The time limit forbade me to edit the post.

Or you could have checked for a v24 client. It did not have the sanity check.

OK, this has now been implemented on the View Assignments page after regenerating one or more assignments. Below the text to cut and paste there appears a "Download WORKTODO.TXT" button.

Could I ask people check that this works across all browsers and OSs? It works fine under Firefox on Linux, but I'm not sure the HTTP Header MIME type ("application/force-download") will work under Internet Exploder.

I'll also add this abiliity to each of the worktype reservation pages, so it will be available after someone reserves work initially. This is obviously so they don't have to go through the extra steps of Viewing Assignments, selecting the new ones, regenerating and then downloading.

Does anyone actually use IE? :surprised

Unsurprisingly, it works perfectly under Windows on Firefox 3, Opera, and Chrome. IE fails to download (just displays as HTML, as in line breaks ignored).

It would probably be better to do this:

header('Content-type: text/plain');
header('Content-Disposition: attachment; filename="worktodo.txt"');
echo $worktodo;

Cool. Thanks James.

Of course, I had to modify the PHP to be Perl....

Can you test it again, and make sure it works under Internet Exploder?

Amazing, it does!
I'm sure I'll be the last person ever to know that.

@James Heinrich && chalsall :
Good job!

p.s. still waiting for my visualization-related request, see OP....

edit: didn't realize this is first-in-last-served list (just kidding).

This number was ECM'd to ~200-bit (t60, i.e. 60-digits). It is virtually impossible for it to have 62, 63, 64-bit factors, or even 80-bit or 100-bit factors (if you are thinking about going forward, forward and beyond in your endevour). If you are thinking that "ECM misses some tough factors", then you are thinking about P-1. Estimate the corresponding probabilities using the known formulae.

That is a fairly poor excuse to effectively waste it. Instead, it is a good idea to let the hardware run something useful and mainstream software -- and in parallel let your brain "run" some new and exciting ideas and possibly find something for the hardware. That's my two cents, but of course you can do whatever you desire if your h/w.

I generally agree with everything you said. Did you click the link which follows after "I have the hardware" in my post? I am talking about ECM too, in almost the same words.

Indeed. You certainly saved me a great deal of Googling (and head bashing). It is annoying how Micro$oft still delude themselves that they're so dominate that their Internet browser does just about everything differently than everyone else...

To hopefully help others who have a need for the cross-browser ability to force a download rather than rendering the returned data, the Perl needed (using the CGI Perl module) is:

$q = new CGI;
print $q->header( -type => "text/plain",
-Content_Disposition => "attachment; filename=\"worktodo.txt\"");

And, so everyone knows, I've added the "Download WORKTODO.TXT" functionality to all the "Get Assignment" pages.

Plus, I took the opportunity to implement a request from Dubslow from quite some time ago -- the P-1 assignment page now offers Number of CPUs / Number per CPU / [Worker #n] functionality.

I know you were kidding, but so you know... What you've requested is a bit more "tricky" -- the download request was trivial.

Work on your and Dubslow's requests are already underway in the Mersenne.Info development and testing environment. Plus a couple of other things I've been wanting to implement for quite some time....
