You ... really don't use google do you?

@DanGrossman regular-expressions.info/reference.html more specifically

Tim Stone

@drachenstern Dan is a big picture kind of person, clearly.

drachenstern

lol

Klaus Byskov Hoffmann

I love the unanswered tab. It's my "home" on SO. Is it really going away? Well, see if I care, I have now written my first greasemonkey script and I foresee more to come :-D

Tim Stone

@KlausByskovHoffmann It's not going away, but it's accessible from all sorts of other places.

11:01 PM

@KlausByskovHoffmann It's a subtab of questions: stackoverflow.com/questions?sort=unanswered

drachenstern

@KlausByskovHoffmann in favor of /review

Klaus Byskov Hoffmann

/review is not the same source of rep as /unanswered is

drachenstern

But it can be if done properly

Klaus Byskov Hoffmann

I guess so, yeah

Moshe

nite folks

George Edison

11:04 PM

@TheRenamedException: Are you around?

The Renamed Exception

I am

George Edison

Great!

drachenstern

If he's not I'll thwack him for you ... oh

Klaus Byskov Hoffmann

@GeorgeEdison is that your real name?

George Edison

I have the 'almost-final' version of the script.

@KlausByskovHoffmann: Nope.

Klaus Byskov Hoffmann

11:05 PM

Or is it Nathan Osman?

drachenstern

@KlausByskovHoffmann what is a name?

George Edison

Maybe.... [looks around...]

drachenstern

I rather envy my buddy who changed his name legally to Zelig Enoch

George Edison

@TheRenamedException: I'm looking for last minute beta testers.

Klaus Byskov Hoffmann

It's just because I attributed you in my script, and I don't want to have the name wrong

drachenstern

11:06 PM

@Moshe did you figure out what you need to change on your regex so it doesn't match exactly one alphabetic character?

George Edison

The script now updates the posts in place.

Tim Stone

@GeorgeEdison Did you get my StackApps chat ping, by the way?

George Edison

@KlausByskovHoffmann: Thanks!

That's right.

@Tim: Yup.

Klaus Byskov Hoffmann

cool

George Edison

I've fixed that and a few other bugs.

Tim Stone

11:06 PM

Alright, awesome :)

The Renamed Exception

@GeorgeEdison Um, I am just about to head out for the night but I can test tomorrow if that's not too late

George Edison

That's fine

It'll be on Meta soon.

drachenstern

/^[A-Za-z]+$/i <-- probably what you intended

mootinator

Um

George Edison

@Tim: files.quickmediasolutions.com/userscripts/circles.user.js

mootinator

11:08 PM

Wouldn't /^[A-Z]+$/i work?

George Edison

That's got all of the changes, but...

be careful!

Tim Stone

Thanks!

:O

George Edison

It actually updates the post with the changes.

Just keep that in mind.

Tim Stone

Oh, but only if I click save right?

George Edison

Yup.

Tim Stone

11:09 PM

Alright, I think I can manage to keep myself out of trouble then. I'll give it a whirl.

George Edison

Anyone who doesn't want to try it can watch a short video I made.

drachenstern

@mootinator does that match on 123ABC ?

George Edison

files.quickmediasolutions.com/userscripts/videos/circles.ogv

^---- Demo video.

drachenstern

@GeorgeEdison can you post that to youtube or something so I can be lazy?

or give a non-.user.js version for playing along at home?

Tim Stone

Damn, maybe we should have videos for our scripts too, hahahah.

Getting all fancy. :P

drachenstern

11:11 PM

haha, idk about all that

George Edison

@drachenstern: I can give you a Flash version...?

drachenstern

@GeorgeEdison I'm trying to avoid opening it outside of the browser, that seems like work

mootinator

@drachenstern I guess it really helps to know what the purpose of a regex is O_o.

badp's sockpuppet

@drachenstern just add a video tag in any page with the inspector and use that as the src

drachenstern

@badpssockpuppet that works with OGV?

Tim Stone

11:12 PM

@mootinator The purpose of all regexes are to capture unicorns.

drachenstern

@TimStone I thought that was the purpose of virgins

badp's sockpuppet

@drachenstern Most likely

Tim Stone

@drachenstern We aren't a cult, don't be silly.

drachenstern

@TimStone says who?

mootinator

@TimStone /^.*(unicorn).*$/g Aha, gotcha $1!

Tim Stone

11:13 PM

@drachenstern I opted out of that newsletter.

@mootinator The hope is that if we can master unicorn capture, Pokemon will come next.

George Edison

Uploading FLV...

mootinator

@TimStone But then we'd have ALL the problems.

George Edison

files.quickmediasolutions.com/userscripts/videos/circles.flv

^---- FLV version.

drachenstern

<video src="http://files.quickmediasolutions.com/userscripts/videos/circles.ogv" controls="controls" />

hey that did work easily enough ;)

interesting little script. Not sure why I wouldn't just open it in paint.net

hello chrome, I love you

I just thought you should know that Chrome. And I don't plan to leave you anytime soon.

George Edison

For anyone else: files.quickmediasolutions.com/userscripts/videos/circles.html

^---- Embedded Flash player.

drachenstern

11:19 PM

@GeorgeEdison oh sure now you do it :p

George Edison

Has anyone tried it?

Does it work alright?

drachenstern

WAITASECOND

it saves the image and reuploads it?

George Edison

Yup.

Tim Stone

@drachenstern Yeah, I take it you missed the bold warning text? :P

George Edison

Heads to Meta to see what got messed up...

drachenstern

11:21 PM

@TimStone I didn't grok immediately what "be careful" meant

Klaus Byskov Hoffmann

Oh, I see, I was trying it on an avatar yesterday, maybe that's why it wasn't working too great :-D

The Renamed Exception

@drachenstern is causing trouble again!

George Edison

@KlausByskovHoffmann: I fixed that.

drachenstern

I am not, I am writing code

George Edison

@drachenstern: Did it work, though?

drachenstern

11:22 PM

trying to figure out which bit of my page is responsible for not allowing renames of blank spaces

@GeorgeEdison I didn't try it

Klaus Byskov Hoffmann

@GeorgeEdison great!

The Renamed Exception

Ok I'm off, catch you guys later

George Edison

See you later...

...don't forget to check Meta for an announcement.

drachenstern

oh haha, I think I already fixed it earlier and didn't realize it :\

yay for fixing bugs prematurely!

George Edison

@drachenstern: If I create an answer in the formatting sandbox, will you try the script on it?

drachenstern

11:24 PM

probably not, but thanks for the offer

Klaus Byskov Hoffmann

I wonder if we will be seeing loads of suggested edits with poorly drawn unicorns all over the questions' images

George Edison

So you won't try it? :O

@KlausByskovHoffmann: Would you like to try it?

Klaus Byskov Hoffmann

sure, why not... only I wouldn't know which question to "edit"

Dan Grossman

George Edison

@Dan: Okay.........

@KlausByskovHoffmann: I'll make an answer for you.

@KlausByskovHoffmann: meta.stackoverflow.com/questions/3122/formatting-sandbox/…

Klaus Byskov Hoffmann

11:26 PM

@GeorgeEdison cool, just give me a link to the new script and a link to the question and I'll get drawing :-)

George Edison

There's one for you to mess up.

files.quickmediasolutions.com/userscripts/circles.user.js

^--- The script.

@DanGrossman shouldn't be allowed, as NT4 and NT6 introduced completely new profiles, etc. However, just installing windows over itself repeatedly should work. Gonna watch

Hm, that's more interesting than I previously believed.

George Edison

11:30 PM

@badp: You realize that I know where you are now :)

badp's sockpuppet

@GeorgeEdison Oh, I don't think I am the one in Richmond, Canada.

George Edison

@KlausByskovHoffmann: Are you using FF?

Klaus Byskov Hoffmann

yes

George Edison

@badp: No? That's where your IP is from.

@KlausByskovHoffmann: Does anything show up in the error console?

badp's sockpuppet

@GeorgeEdison That's not my IP.

Klaus Byskov Hoffmann

11:31 PM

Yes, when I drag, I get 100+ errors, all saying the same thing: An invalid or illegal string was specified" code: "12

George Edison

It's not mine either.

@KlausByskovHoffmann: Hmmm... does the red still show up?

Klaus Byskov Hoffmann

No

badp's sockpuppet

Could it be that's imgur's IP?

George Edison

Oh yeah...

badp's sockpuppet

George Edison

11:34 PM

...no, that's not imgur's, that's my server's.

badp's sockpuppet

Nope, that's imgur's.

George Edison

I mean the Richmond one.

badp's sockpuppet

@GeorgeEdison Yeah, I thought so and that makes your script quite more interesting than I previously believed!

...or complex, at any rate.

George Edison

Which one?

The PHP-image or the userscript?

badp's sockpuppet

Hm, I didn't think you had a PHP-image server to begin with

just some black magic with canvas stuff or whatnot.

Dan Grossman

11:35 PM

"Impressively, all the colors set up during Windows 2.0 were still present 13 years later"

badp's sockpuppet

I see it isn't that simple

mootinator

gives up

George Edison

@badpssockpuppet: The PHP image is dynamically generated using IP geolocation data.

It highlights a slight privacy concern with external images on SE sites.

But the downvote seems to indicate that nobody cares.

Dan Grossman

"Of note is the Program Manager groups created in Windows 3.0 still present and functional in Windows 7. This is nearly 20 years of application compatibility."

badp's sockpuppet

@GeorgeEdison Uh, I meant the bit of software on your server that fetches the arbitrary images, the data with my freehanded circles, sticthes them together, puts on imgur and sends back the url to edit in place.

George Edison

11:39 PM

@badp: That's even more complicated.

...since it's not even supposed to be possible.

drachenstern

@DanGrossman that was impressive

badp's sockpuppet

Well, that's what's interesting.

George Edison

A JS script is not supposed to be able to access iframe content from another domain.

...but I figured out a very clever solution to that.

drachenstern

@GeorgeEdison you should share with us ;)

badp's sockpuppet

Maybe websockets would've been easier :)

George Edison

11:40 PM

Okay, so first off, the HTML5 canvas data is captured.

Then it is sent to my server using an iframe.

The client JS code polls the iframe to see if it can access the content.

Meanwhile, the server stitches everything together and gets an imgur URL.

It then sends a 301 redirect to a specially crafted Meta URL that has the new image as a parameter.

2

The client code can then access the iframe since it contains data from Meta.SO.

The source of the iframe contains the parameter with the new imgur URL.

badp's sockpuppet

Yeah, JSONP would've been easier :)

George Edison

...and that completes step one of three.

@badp: JSONP doesn't support POST.

badp's sockpuppet

I see.

drachenstern

@GeorgeEdison that is actually a good consideration ... I will consider this a little longer

George Edison

Step two is to get the current markdown data.

First the API is used to get the GUID of the latest revision.

Then AJAX is used to get the current markdown.

Last step consists of replacing the image in the markdown with the new one...

...replacing HTML entities, and then creating a new iframe (with a POST form) with some parameters.

That form contains all of the same data as it would if you were actually editing the post.

So, when that form is submitted, you see the changes.

Simple, no?

badp's sockpuppet

11:45 PM

A+++ would inject again

drachenstern

That's actually pretty crafty

Moshe

@drachenstern *

drachenstern

@Moshe or +

Moshe

@drachenstern Ah, well all the same, it works

badp's sockpuppet

I'm going to star the most interesting step as a star representative of everything else.

drachenstern

11:47 PM

@Moshe just depends on what you want

@badpssockpuppet you and I agree. See :544308

All done.

badp's sockpuppet

is it users registered in the last, er, 45 days?

Rebecca Chernoff

@GeorgeEdison erm

waffles

yes 45 days = "new user"

drachenstern

@waffles I was initially confused when it went -> instead of VV

George Edison

@RebeccaChernoff: Yes?

badp's sockpuppet

11:50 PM

(with the 'in x days' being the amount of time since they signed up, I assume)

waffles

@badpssockpuppet correct

Rebecca Chernoff

You do realize there's a site for scripts...

George Edison

Yes.

I will post it there too.

However, it deserved to go on Meta, since it's for Meta.

waffles

I seems to be giving useful lists for the smaller sites : photo.stackexchange.com/users?tab=newusers

drachenstern

@waffles my one remaining complaint still stands ;)

George Edison

11:51 PM

...right?

Rebecca Chernoff

What exactly is the point of the script? |:

badp's sockpuppet

It looks very awesome indeed, @waffles.

@RebeccaChernoff Draw mustaches on people's faces effortlessly. And freehand circles, but mostly mustaches.

drachenstern

@waffles the script shows for 45 days?

Tim Stone

@badpssockpuppet Aye

George Edison

@RebeccaChernoff: To enable freehand circles to be drawn effortlessly!

drachenstern

11:52 PM

@waffles I think that's too wide for younger sites. For instance, with dba.SE ~ 45 days is nearly everybody

Rebecca Chernoff

|:

waffles

@drachenstern ... its a lose lose situation, the old vertical then horizontal listing is not effective when stuff gets tall

drachenstern

@waffles yeah I was contemplating that

George Edison

@waffles: Have you seen it yet?

You're pro-Freehand-circles, right?

badp's sockpuppet

@drachenstern eh, this is a much smaller corner case than those that affect the reputation tab

drachenstern
