Cone bottoms for JamesRL

[Julian]

I've just started a page on cone bottoms.  The page is far from complete but Jim has offered to assist, so it's posted for editing proposes only.

Didn't know he'd taken up condiment brewing

Yes, seen it.

I thought it was a little confusing and could be improved ... but I'm not sure that I've achieved that though!

I did want the page to be original so it was wholly credited to the wiki.

I very much like the calculator to which JTF link, I'm sure Tony could knock one up, but we have issues with interactive content within the wiki.

[Tony]

There must be a way - I'll take an action to try and find out.

K.H has just kindly pointed out my mistake.  I was wondering what the hell you were on about before he did!  My minor typing error is now corrected.

And any-bloody-how, jam isn't a condiment!

That would be great.  Some of the other calculators you've done should be on the wiki too,

[Keef]

Could you not just have a downloadable spreadsheet like the other excel stuff on here?
If it interacted away from the Wiki, it's safer for the Wiki and the end user gets a copy to keep on their computer.

[Tony]

Could do, the catch is that at least one of the javascript calculators has been set up such that you edit any box and it calculates the rest (pump pressure head one).  I don't know how you could do that with a spreadsheet without resorting to visual basic.

The existing JS ones are here:

I see Jim has editted the cones page.  Didn't realise the cone radius is set to the final diameter, that's quite a lot smaller.

Aren't we all up late today!

[Keef]

I see the problem. Would it be too much work/hassle to have the calculators on a remote site and link to them?

[Tony]

Well we could link to them from the wiki right now - it's just that it would be nice to include them "wrapped up in a wiki page" as it were - actually in a page on the wiki.

The issue isn't the location of the files themselves, it's in allowing enabling embedded javascript on wiki pages (presents a security risk if malicious code is added).  I guess for most wikis that's a massive risk because anyone can come along and edit a page to add javascript, whereas here we're a little more selective over who can edit pages.

Thinking about it, perhaps it isn't such a bad thing to allow javascript on wiki pages?

[Julian]

I have a nice graphic from Jim to redraw and Jim has kindly offered to add some blurb once it's published describing a geometric method of arriving at the development of a cone.  But I still think if we could have a calculator similar to the JTF one it would improve the page no end.

Any further thoughts on allowing javascript?  If it's a matter of who has the rights to edit the wiki, we could police it differently.  There have only been a handful of contributors so far, so we could remove editing rights from all but those who have contributed and set up a system for new people wishing to contribute, to request editorship rights.

Any thoughts?

[Tony]

If that's the only way we can do it.  It could be that we can limit editting of particular pages with calculators to a subset of trusted members - without affecting other user's abilities to edit the rest of the wiki.

If I remember rightly it is possible to set up a page vetting system before updates are published too, so those pages would have edits vetted before admin approved them to be shown in the wiki.

Sorry I've been  little overrun with tasks lately otherwise this would already be figured out - just need to spend a bit of time on it.

We do want this to be the best wiki, and I wouldn't want a technical issue to prevent us from making it such.

[Keef]

Excuse my ignorance but could the pages with calcs not be locked in the same way that Julian has locked the 'new page' and 'creating pages' pages? This would leave all pages open for editing except those that contained javascript.

[Tony]

Probably.  I don't know how Julian did that though!
