Introducing the PF Library

[Greg Bernhardt]

There something annoying about the auto-hyperlinking system which causes certain keywords corresponding to existing entries int the library to be linked, even if the word is used in a collequial context. Like for example, the word 'limit' or variations such as 'limited' would all be linked to the library even though the term may not have been intended for its formal mathematical meaning.

Working on this now. thanks

 

[Defennder]

Thanks Greg.

 

[neutrino]

I'm late in say thing but, thanks a lot, Greg. It is a wonderful addition to this great resource of a site. And thanks to the contributors and moderators, too.

Looking forward to exploring the library.

The symbol ≥ cannot be used in Definition/Summary, although > can be.

If I type alt-> on my Mac as usual, which gives ≥ anywhere else, the html code &# followed by 8805; appears instead.

alt-> gives standard code, which should appear as ≥ on any browser … why does it not work in this particular field?

(I also tried typing which didn't work either)

If the same person amends the same field twice in quick succession, it goes down as two edits in the Edit log.

Perhaps this should be changed, especially since there is no preview facility? ​

test... triangles

triangle linkage working?

 

[tiny-tim]

The title field in See Also is restricted to 22 characters. Is that intended?

May I suggest that the Report button be changed to Contact, or Contact Editor … "Report" looks as if it's only for sniping.

 

[jostpuur]

To help avoid cluttering, we've setup the links to remain black text, but feature a dotted underline.

The links are jumping on the viewers eyes too much now, with capital letters and different color.

 

[awvvu]

Can we arrange for the auto linking to not change the capitalization of the word linked?

Haven't seen any response to this, but I second it.

blah blah angular momentum blah blah.

 

[_Mayday_]

Has a preview button been mentioned by anyone yet?

 

[cristo]

Has a preview button been mentioned by anyone yet?

Yes, see posts #8 and #9: Greg says he has noted this as a future feature.

 

[_Mayday_]

Ah right cheers!

 

[Physicsissuef]

Can I ask you why there isn't any edit button? I urgently need it. Thanks.

 

[Gokul43201]

Only PF staff has the ability to edit entries - for quality control. If there's an edit you'd like to make, you can post it as a comment, and if it's reasonable, a staff member will make the edit.

 

[Physicsissuef]

Ok, thanks. And why In the definition box, the tags for bold or italic don't work?

 

[Kurdt]

Ok, thanks. And why In the definition box, the tags for bold or italic don't work?

I don't think bbcode is enabled in that box.

 

[Physicsissuef]

Yes, but it should be. Please enable it.

 

[Greg Bernhardt]

Yes, but it should be. Please enable it.

I'll look into it

 

[Physicsissuef]

Can I ask why one of my posts in the library, about equation of line, is deleted? I put so much effort in it. Please return it back. Thank you.

 

[Kurdt]

Its not deleted, they have to moderated first. During that time they aren't visible.

[tiny-tim]

First entry in an edit log is now shown as the item creator.

Hi Greg!

I've noticed that Physicsissuef has gone to the trouble of creating three Library entries in the last few days, but none of them has the creator shown in the edit log.

Has this facility been cancelled?

Can I ask you why there isn't any edit button? I urgently need it. Thanks.

(It's so that everything is seen by a moderator before it becomes official.)

You can click the REPORT button.

(That button is for nice reports, as well as nasty ones!)

Then someone will see it much sooner than if you post it as a comment, and you can include the amended text in the report.

Thanks; in future if you see spam please use the "report" button, in the same way that you would report a thread containing spam.

Auto-linking

i] I've noticed several words auto-linked to Wikipedia (Light, Photons, event horizon, General Relativity, Gravitational lensing) … see https://www.physicsforums.com/showthread.php?t=239070
Is this a general policy?

ii] Auto-linking is not working on the Lorentz Gauge entry, neither "in" nor "out".
Does that mean it can be selectively turned off?

iii] I'm contemplating an entry on "joule".
It should of course be spelt with a small "j" (when not at the start of a sentence), but the auto-linking will capitalise it every time. Can the capitalisation be selectively turned off?
(Could be avoided by tilting it "The joule" … but then it wouldn't auto-link at all. )

1. Those aren't autolinked, the author put those in
2. Lorentz Gauge is linking for me
3. Autolinking does not capitolize, it depends on how it is written in the library

hi greg!

i] you're right … i should have checked the code …

never occurred to me that anyone would go to all that effort!

ii] hmm … it's certainly working in this thread … but not in posts #1 or 3 in https://www.physicsforums.com/showthread.php?t=238727, for example, … and there's no entries in the Recent forum threads field

iii] aah! thanks, greg!


Just testing … will remove on edit …

Only linked once per post

 

[ehrenfest]

I don't know if this has been posted before but I think auto-linking is a horrible idea. I have never seen that done anywhere else and think there is good reason. It causes things to be linked completely out of context. For example, I work at hospital. Also, I just think in principle there is something wrong with PF forcibly altering what I type. I should have "creative license" to decide whether I want things to be linked or not. You should not just impose your PF Library on everyone since that undermines my control over my posts. Its not like the PF library is the god-given definition of every term that it contains.

 

[tiny-tim]

… It causes things to be linked completely out of context. For example, I work at hospital. …

I like the autolinking … it's a useful idea … does it matter that it's not perfect?

Though perhaps autolinking could be turned off in the lounge (also mobile phones, personal stereos, hand-held games, and lava lamps)?

 

[matt grime]

I agree with ehrenfest - in fact I came here independently to mention this unfortunate side effect owing to having the word work autolinked in a post of mine.

I'd imagine a simple tag system could be written into the software, like a \ref or \cite tag in LaTeX.

Perhaps this has been mentioned too: why the menu only access to articles? This makes it very fiddly to see what the articles are, and their current status - 3 mouse clicks to find out that 'maths -> algebra -> homologic' is an empty article is annoying. Not least because there is no such thing as 'homologic' in English. Prseumably it was supposed to be homology, or homological algebra.

 

[Kurdt]

I think that a tag system would not be beneficial since people would have to know exactly what was in the library to use it. Perhaps a checkbox system like disabling smilies or automatically parsing links would be better.

Matt: There is a text search below the three drop downs one can use and you don't have to choose a category in all three drop downs to search.

 

[matt grime]

That supposes I know what text to search for.

Suppose I was feeling like adding to the entries wanted to create some topics, or check the current topics to see what there was to extend/rewrite. It would take 3 clicks (menus reset to empty fields on my laptop) to get to any single entry. Well, my wish to add to the knowledge there just evaporated. (And that was exactly what happened when I looked at it yesterday with the intention of either creating some entries, or refereeing ones that already existed.)

 

[Kurdt]

That will be a problem when the library gets a greater population of entries. For now one could just select mathematics in the first box and see all the entries under that category which is not very many at the moment.

https://www.physicsforums.com/library.php?do=navigate&topicid=1&stopicid=-1&sstopicid=-1

I think its similar to something like wolfram mathworld where you'd have to click at least 3 submenus to get to where you want to be.

What type of menu system would you suggest matt?

 

[matt grime]

Your wolfram analogy is slightly misplaced - their system does not use drop down menus. It is hierarchical with the ability to do simple depth first search - i.e. it allows you to use the back button to get back to the list in the algebra section, say.

As Kurdt has pointed you don't need to select all three drop downs. Disabling the autolink in some forums will be a future feature.

 

[matt grime]

Ah-ha. I didn't understand that. Then can we alter the labels on the drop down menus from

"Then select"

to

"optionally select"?

 

[Greg Bernhardt]

Library guidelines changed.

Item Titles:

Why hasn't "List of Standard Integrals" in https://www.physicsforums.com/showpost.php?p=1763925&postcount=17" of the same name?

 

[Kurdt]

I think it must be turned off at the minute while Greg is trying some new things.

 

[tiny-tim]

ooh … I think you're right …

Hi Greg!

May I suggest that there be an exception when a word is a person's name?

For example, the autolinking is changing "Newton's second law" in posts to "Newton's second law" (eg, in https://www.physicsforums.com/showthread.php?t=135559") …

which presumably is doing exactly what the guideline change was intended to avoid?

I've just amended a Comment on a Library entry over 60 hours after I first made it.

Shouldn't there be a much shorter time limit on editing Comments?

Why is the autolinking not working for "electric units" https://www.physicsforums.com/showthread.php?p=1814928#post1814928"?

Have you got your autolinks disabled?

Test: electric units

Just popped into the library for the first time, and it seems like a great idea. Will try to contribute soon. Thumbs up!

mmm … coffee!

Hi Kurdt!

That's weird …

I see "electric units" underlined in your post, but not in mine.

How can that happen?

I love the idea of people "popping in" to the Library!

Perhaps we could have a coffee lounge by the entrance, to entice people in, and maybe a gym and a shopping mall and a surf beach round the corner? Graphics, anyone?

 

[Hootenanny]

Goto My PF > Edit Options and ensure that the "Disable Auto-Linking" check-box is cleared.

Done that … it's always been cleared.

But I'm seeing autolinking in one post (#144), but not the other (#143).

Do you see autolinking in my post #143?

No, perhaps it has something to do with the quotation marks:

"electric units" vs. electric units

 

[tiny-tim]

No, perhaps it has something to do with the quotation marks:

"electric units" vs. electric units

hmm … possible …

but I don't see underlining in either case in your post …

if the quotation marks stop it the first time, surely the second time becomes the first time, and … ?

(and it's still not showing in the thread I referred to)
