Otherwise rm will say, "Do you want to delete this directory? Do you want to delete this file? Really delete this file? What about this one? I like this file, can we keep that one? Ok, the directory is empty, do you really want it gone?"

Moshe

9:28 PM

@Josh Yes, I saw that before.

Josh

@Moshe the r is (obviously) for recursive

Moshe

y, enter, y, enter, y, enter

@Josh I got that.

Josh

ok just making sure :-)

Tim Stone

@Josh It'd be much more exciting if it stood for "random" though.

Josh

My brother is an Apple Genius. When he was in Cupertino for training, I got a random IM from him one evening. "Josh, what's the Terminal command on mac to open a file?"

I laughed out loud

radp

9:30 PM

@Josh so what is it? :)

I know Gnome has gnome-open

Josh

open

:-D

@radp As in, open /path/to/file

radp

@Josh ah, Unix and their insultingly simple command names

Moshe

@Josh Well, in Linux, to run a program, you need to remember ./ or is won't recognize the binary itself and open it.

Josh

or, open -a /path/to/Application\ to\ use.app /path/to/file

Moshe

@radp wishes he had stars left

Josh

9:31 PM

@Moshe this isn't quite true

but, I can't search unix.SE for "./"

Moshe

@Josh I refer to the time I wanted to play Urban Terror on my Ubuntu powered HP egg-griddle.

(Yes, it got hot enough to cook on.)

radp

@Moshe That only applies for executables in the current directory and not in the path

Moshe

@radp - Ah, that's what I was doing.

radp

here we're talking about documents

Moshe

cd path/to/urt

Josh

9:32 PM

@Moshe the reason for this is, when you type a command (rm for example) the system searches for a binary file matching that name in your $PATH

radp

so I guess:

Moshe

./urt.filename

Josh

@Moshe rm is actually /bin/rm

Moshe

Ah, okay.

Josh

but you can just type rm because $PATH contains /bin

Moshe

9:33 PM

@Josh - Got a second to check something out?

I made this litle jQuery widget.

radp

open www.google.com
open settings.py
open kitten.jpg
open BUSINESS.ppt

Josh

if you enter into a Terminal (mac too): export PATH=$PATH:./ then you won't have to type ./ anymore

Moshe

On a website I'm working on.

Josh

HOWEVER THIS IS A BAD IDEA!!!!!!

radp

(that's what open does right?)

Moshe

9:33 PM

Bitachon.org/new

In the top left there is a button.

When you click on it, the container slides out and takes over the topbar.

A form should appear.

Josh

Because if I create a file in your home directory called rm and it's actually, say, a rootkit, then you will type rm some.file and may execute my rootkit instead of the rm command

So having to type ./ before a command in $PATH is desireable

Moshe

@Josh Ah, that's pretty funny.

@Josh Yes, like passwords.

Josh

you're saying, "I acknowledge this command is in this directory and I really do mean to execute it

radp

@Josh to be honest that'll never happen

because you appended ./ at the end, so it'll be the last directory sought in

Josh

there's a great post about it on Unix.SE but I can't find it

@radp yes, good point

Moshe

9:36 PM

bitachon.org/new

Josh

I'll go browse to find the question @radp :-)

radp

@Josh Well yes there's surely an example of very bad things that can happen

Just rm isn't one of them

Josh

@Tshepang do you know the one I mean?

Maybe it was even one of your questions :-)

@radp You're right

Tshepang

@Josh sorry I wasn't paying attention

Moshe

jQuery question

Tshepang

9:41 PM

and no, I'm not familiar with the question

Moshe

I'm storing a form in an javascript variable

Josh

@Tshepang It wasn't one of your questions, sorry :-)

@Moshe OK

Moshe

how can I reattach the event handler to the form when I display it?

@Josh - On bitachon.org

When the user clicks on the button on the top left, a form appears.

The form's submit button has an event handler which creates an AJAX request.

Josh

ok...

Moshe

In that same event handler, the form's contents are stored and then the form is replaced by a "loading progress image", until the AJAX returns.

When the AJAX returns, the image is replaced by the result of the request.

The user can then close the form.

Josh

9:45 PM

ok...

Moshe

When the original button is clicked on, the form is restored.

But the "onclick" handler seems to be ignored.

You can see the live site at the link I've been shamelessly plugging for the last 10 minutes, or the code on GitHub.

Site:

bitachon.org/new

Josh

sounds like some debugging is in order. I will have a look when I finish my own debugging

Moshe

github.com/MosheBerman/Bitachon.org

@Josh - Thank you.

I just wonder how I can reattach the event handler to the form object.

Josh

how do you attach it in the first place?

Moshe

In my onReady event.

Josh

9:48 PM

what specific code do you use?

Moshe

$('#submitButton').click(function(evt){

github.com/MosheBerman/Bitachon.org/blob/master/bitachon.js

Josh

and you remove #submitButton from the page?

Moshe

The last part is the submit button, the form show/hide is separated by two comments.

I do remove submitButton from the page.

Josh

then when you add it back, just call `$('#submitButton').click(function(evt){ again

Obviously, function(evt){ should be assigned to a var

Moshe

Beat me to it.

drachenstern

9:53 PM

@Josh @moshe alternately use a live event handler like thus $('#submitButton').live('click',function() ...

Josh

@drachenstern What does that mean exactly?

Moshe

@drachenstern - Interesting. That might be better for my purposes, assuming I understand what you meant.

drachenstern

api.jquery.com/live

Q: I accidentally chmod -R +x on a directory. How do I restore the correct permissions?

Well, to be specific, it was chmod -R 755. Now every file is executable, which I don't want. I am thinking that I should look at the first two bytes of each file for the #!, but will this cover everything? Should I instead use file to look at everything and base my decision on that? Or, more like...

OUCH

drachenstern

it means that anytime an element is introduced to the page that matches the selector, it will get the event handler defined therein

Josh

9:56 PM

@drachenstern oh really, that's very handy

cool

drachenstern

Honestly I figured you knew about it

It's been discussed in here three or four times, and @Moshe should've learned about it by now with his userscript questions and the responses from @RebeccaChernoff and @YiJiang

Moshe

@drachenstern I did hear about the concept, not the actually code implementation. I wasn't really serious about that userscript.

But, yes, that's handy.

Josh

@drachenstern Last time I coded something in jQuery was 9 months ago

drachenstern

I understand that you weren't serious about the implementation, but the rate at which you absorb information I would've thought you'ld have grasped .live()

Yi Jiang

@drachenstern Actually, it relies on event bubbling to do the trick

drachenstern

10:00 PM

@Josh indeed, I can go months without writing any javascript ... I'm going to start a couple projects soon ... very soon

Josh

And what, you think I pay attention to serious discussions in here @drachenstern? Come on, you know me better than that!

Moshe

@drachenstern I never bothered to look it up. My fault.

drachenstern

@YiJiang ok but the concept :p

Moshe

Anyways, @drachenstern -- thanks, it worked!

drachenstern

@Josh not you, @moshe ...

@YiJiang pedantics ...

Yi Jiang

10:01 PM

@drachenstern You're welcome

Josh

@drachenstern Ok. I was referring to "It's been discussed in here three or four times". Besides I'm a Prototype.js guy. Ask me anything about Element or Class.create :-D

drachenstern

@Josh anything?

Josh

I've never used .live() but I will next time I use jQuery!

drachenstern

@Josh sorry, let me try again anything about Element or Class.create? :p

Josh

@drachenstern Yes. if I don't know it I will probably want to :-D

drachenstern

10:02 PM

@Josh I actually may need to pick your brain then, I know jQuery is fun and all, but for what I want to do it may not be the right toolchain.

Moshe

Never touched Prototype.

Josh

@drachenstern Sure thing, just ask away :-)

drachenstern

will do

Josh

@Moshe I did not chose it as a holy-war, mine-is-better-than-yours kind of thing. I just learned it first because it came bundled with Ruby on Rails

Moshe

@Josh - I don't know that either, not accusing you.

Josh

10:04 PM

Now all my code is heavily based on it. (And I love Class.create :-)

Yi Jiang

@drachenstern If you're looking for some of the util functions you can find in Prototype, you should also have a look at underscore.js

Josh

@Moshe I know. Just fending off inevitable attack from @radp ;-)

drachenstern

@YiJiang interesting ...

Josh

@YiJiang hm, I'll have to check that out, thanks

Moshe

@YiJiang What's that @YiJiang?

drachenstern

10:06 PM

for the time being, if you guys know of any rock solid ("tutorials","whatevers") on those two I'll be very glad if you mail them to me on gmail ... I'll stick 'em on my list of stuff to read soonest.

Yi Jiang

> Underscore is a utility-belt library for JavaScript that provides a lot of the functional programming support that you would expect in Prototype.js (or Ruby), but without extending any of the built-in JavaScript objects. It's the tie to go along with jQuery's tux.

documentcloud.github.com/underscore

drachenstern

So I would use them together ... interesting

Moshe

Question: When designing a form...

Josh

AH HA! FINALLY!!!!

4

Q: Why do we use "./" to execute a file?

Why do we use ./filename to execute a file in linux? Why not just enter it like other commands gcc, ls etc...

command-line executable

Moshe

if the form has a small bounding box, do you go with the "one box at a time" approach?

Yi Jiang

10:09 PM

@Moshe Explain what you mean when you say one box at a time

radp

@Josh Whose is the tick? :P

Josh

of course @radp had the accepted answer to that question

radp

I don't know why I got 18 less upvotes, we're basically saying the same thing.

Josh

@radp WHERE WERE YOU AN HOUR AGO WHEN I STARTED SEARCHING????? :-)

Moshe

@YiJiang - Forms that show one input at a time, like a survey.

Yi Jiang

10:10 PM

@Moshe Depends on how small (area) the form is, but usually for small (number of fields) forms the answer is no

Josh

waaaaaaaaaaaaait

just a damn moment

36 mins ago, by radp

@Josh to be honest that'll never happen

radp

@Josh Wondering what quesition was it about, since the one you linked is unrelated.

Moshe

@YiJiang - Why? When would I use that approach then?

Josh

headdesk headdesk headdesk headdesk headdesk headdesk headdesk headdesk

radp

@Josh O_O

Tim Stone

10:11 PM

@Josh You know you commented on an answer to that question right? :P

Josh

Ok. That's enough of this stupid chat thing. i think I'm going to try doing the work thing for a while and see if I'm better at that...

Yi Jiang

@Moshe When you have a very large number of fields, and you need to split it up into multiple pages

radp

@Josh I'm glad you saw the light

Josh

@Pekka can take my place at the bar :-)

Moshe

@YiJiang - I am asking for a name and address.

Pekka

10:13 PM

@Josh can't, have to work too :)

Tim Stone

@Josh Enjoy, happy productivity

Josh

haha thanks @Tim :-)

Moshe

@TimStone wishes he could star

laughs at @Josh who will respond to this and NOT get anything done.

Pekka

@Yeah same here. I've been out of stars since 01:00 GMT

Josh

@Pekka here you go , use this in the meantime:

Moshe

10:15 PM

@Josh - HA! I knew it.

drachenstern

@Josh star <-- searchability later p;)

Pekka

@Josh Wow, that one's from the mother lode!

Rebecca Chernoff

@Pekka You used 20 stars in an hour? What the heck were you starring?

Scratch that. I don't want to know most likely.

Josh

Tim Stone

@RebeccaChernoff Ah good, you're learning :P

Josh

10:17 PM

(Since I can't actually star you @Rebecca)

Oh wait. I was going to quit chat. Sorry, forgot

Yi Jiang

@RebeccaChernoff Well, if you say one 'oy' every five minutes, a lot of us would be out of votes in an hour

drachenstern

@Josh same here, right as the boss walks in and I'm hitting send :p

Pekka

@RebeccaChernoff um

Only pertinent contributions

That I felt enriched the value of the chat room

And embiggened the spirit of everyone in it

No I admit it, I was building a wall of stars :)

Josh

10:34 PM

@drachenstern BUSTED!

@Pekka Oh I want to start this so badly!!!!

drachenstern

@Josh almost. He came back in and my head was concentrating on my lefthand monitor (my door is to the left) and I didn't know what was on my righthand monitor ... I kept wanting to look over and see if the room was up, it was not thankfully enough

Josh

hahahaha

Cool site.
