Tavern on the Meta

7:02 AM

It's official, my app has been waiting for review for too long.

@MichaelPetrotta - Okay, watched the video. I got it, I think.

Basically, BW does the whole thing for me but gives progress events. Seems like I still need to call the webpage using some other object.

Michael Petrotta

We all rejoiced when BackgroundWorker came out in .NET 2.0. Well, I did, everyone else looked on with horror.

@Moshe: query the web page in your DoWork event handler.

Moshe

@MichaelPetrotta Can I still use WebClient in BW?

Michael Petrotta

@Moshe: Doesn't have to be another object: the event handler could live right inside your form.

@Moshe: yes, you can still use that.

drachenstern

effing internet ... goes out ... I reboot router ... nothing ... reboot router manually and firm disconnect ... nothing ... I call tech support. Last ditch reboot. They say hello, it connects ... FFFFFFUUUUUUUUUUU

Moshe

Ok, but I think I mentioned that I've got several books and each book has articles.

Michael Petrotta

7:07 AM

the important thing is that BW pushes the work to a background thread.

Moshe

@MichaelPetrotta The app shows a list of books, when the user taps it, a list of articles/chapters appears

Michael Petrotta

Do you want to push data to the listview piecemeal?

Moshe

@MichaelPetrotta Meaning? (I'd like to mimic the table view on iOS, a la Notes or Mail)

Michael Petrotta

Ah. Without knowing more, just kick off a new BW with each user request.

Moshe

Interesting, and the BW will return complete only after the WC is done?

@drachenstern Ask em to send you a new one.

drachenstern

7:10 AM

It's my router :p

I refuse to use their PoS ... I would rather use my own PoS

Michael Petrotta

@Moshe: yes, the BW will call the RunWorkerCompleted event handler when the DoWork method completes.

Moshe

Oh, well rotsaruck then.

@MichaelPetrotta But the WC runs Asynch, no?

Michael Petrotta

(that's really the same thing you said, but with more precise terms)

if the WC runs in the BW DoWork method, then it runs async, yes.

Moshe

I'm saying that the WebClient object works asynchronously so it won't affect the BackgroundWorker... Is that incorrect?

Does the WC not run Async outside a BW?

drachenstern

the WebClient tries to run async where it can, yes. But the framework is smart enough to run synchronously if that's the calls you make.

Moshe

7:13 AM

@drachenstern So if I stick it in the BW, it should do the right thing then?

Sounds like that's what I'm hearing.

drachenstern

Yes

If you don't call the async processes (such as BeginRequest and EndRequest)

Michael Petrotta

if you stick it in a BW, use the sync methods of WC

Moshe

@MichaelPetrotta How so?

Michael Petrotta

most interesting methods of WC have sync and async variants

DownloadString and DownloadStringAsync, for instance.

(the former is synchronous)

Moshe

Thanks

Michael Petrotta

7:16 AM

another way of doing this, avoiding the use of BW entirely, is to use the WC async calls

but I like BW, lots of goodness

Moshe

Right, but I need to get WC data into a ListView. The problem is that the WC is in it's own class, not the default form.

Michael Petrotta

and?

Moshe

I don't know how to get the data from Class A (wrapper class with WC) to Class B (Form Class) and into the ListView. Since it's running asynchronously.

Michael Petrotta

DoWork(MyWebServiceData data)
{
data.InterestingStuff = new MyWCClass().Download()
}

Moshe

And then when it completes, data.InterestingStuff holds my data!

drachenstern

7:20 AM

@Moshe the async calls let you provide a callback

you know how with jQuery you can provide a callback for onSuccess and onFailure for stuff like $.ajax ?

Michael Petrotta

@Moshe: yes. which is provided to your RunWorkerCompleted event handler

Moshe

Yes and Yes

got it

I'm going to take a stab at this later. Bedtime!

Thanks

Michael Petrotta

I think I'm getting punchy.

@RebeccaChernoff Actually, I just realized, some mod (was it you?) came around and edited out the link to the transcript (to the original store URL) on that comment. Geesh, thanks mod, that really killed off the joke.

badp's sockpuppet

4:00 PM

@YiJiang I think the reason is above - the store isn't actually open

Tim Stone

The consequences from ordering before it's official open could be dire.

Yi Jiang

@badpssockpuppet Well then obviously add a landing page which says 'Coming soon' or even a warning 'This isn't ready yet' to the store - the URL is out, anyone coming to this room can see the URL on the right

No point in killing every reference to it

Hogan

badp's sockpuppet

@ChrisF 8.04

still googling for "price of Gas" yelds images like this

ChrisF

It's over £5 per UK gallon -which is bad enough. It's not that long ago that they changed from selling it in gallons to litres because it went over £1/gal

6:01 PM

@badpssockpuppet I raised both eyebrows.

Moshe

6:26 PM

@shog9 like if certain components are available. I was wondering about putting speakers in every room, attached to our main sound system.

Shog9

6:37 PM

@Moshe You could try DIY... But if it's just a shopping question (vs., say, "how can I pull speaker cable into 4 rooms from the main system in the hall closet?"), it probably doesn't belong anywhere.

Hogan

@Moshe You could use sonos -- I hear it is great, but it is not inexpensive.

Moshe

7:26 PM

@Shog9 Thought so. Thank you though.

mootinator

Whew.

Finally got my js doing what I want it to.

Tyler Chacha

Anyone wanna test something for me?

mootinator

@TylerChacha Sure.

Tyler Chacha

sec, it just broke..

So, this is a popup that will run over other applications and load JSON into them from a server

Obviously it is gonna feel weird since there isn't an app to interact with, just the overlay

but, here we go

user: mso, password: msoisawesome

102content.com/storage/js/test.html

needs a back button..

Moshe

@TylerChacha Yea, was gonna say.

Awesome CSS though

Tyler Chacha

7:38 PM

Bah.. it is all made via jQuery..

all the GUI is about 500 lines long..

var d =  $("<div />", {
            "css" : {
                "fontFamily" : "sans-serif",
                "backgroundColor" : "white",
                "border" : "1px solid #ccc",
                "paddingTop" : "10px",
                "display" : "block"
            }
        });

        var o = $("<form />", {
            "id" : "storageLogin",
            css : {
                "border" : "8px solid #EEEEEF",
                "-webkit-border-radius" : "10px",
                "position" : "absolute",

All of it connects to 102content.com/storage, the API I created to save and load JSON

Hogan

css inline?

Tyler Chacha

@Hogan Well, it ends up being inline

I created all the HTML using jQuery

including styling it

mootinator

jQuery does everything

Tyler Chacha

(See that giant piece of code I just posted. It is the Login form)

Hogan

@TylerChacha Yeah, I'm just sayin' The css inline is going to cause you pain in the future.

Tyler Chacha

7:41 PM

unfortunately, without an app there isn't much you can see as a user..

Just the pop-up pains

Once I hook it up to an actual app you'll be able to see what it is doing

mootinator

Is there a json object we can edit using the console and save? ;)

Tyler Chacha

But basically it is meant to take applications that run on localStorage, and take the data they have and save it to a server

and then load it back

mootinator

ah

Tyler Chacha

@mootinator Refresh until you don't get the login anymore. You can use $s.gui.save(dataObject) to save a dataObject

@mootinator And you can use $s.gui.load(function(data){ console.log(data) }); to view what each repository has in it

The main two commands are $s.load(repositoryID, callback) and $s.save(repositoryID, data)

I'll write up actually documentation later, but yeah. Each user has a set of repositories. You can read and write to them with load() and save()

it uses a token based authentication system..

some of this needs to be simplified though..

seems too complicated..

Moshe

@TylerChacha - Hooray for no back button!

Tyler Chacha

7:59 PM

I think the word 'repository' makes it sound too complicated...

Basically this API takes your Application's Data and saves it to a file on my server. Then you can go back and pick which file to open

Yeah. I like that idea. Files instead of repositories..

Now I just need to be able to let the user rename them..

Moshe

@TylerChacha Sounds good.

Hogan

8:25 PM

@TylerChacha How about "Magical Cloud Based Virtual Storage"

Moshe

\O/ I finally loaded data into a ListView!

Hogan

Not as compilcated

Moshe

@Hogan Yea, Microsoft Windows Azure meets Apple iPad!

Hogan

@Moshe Ah... I see your evil plan now.

@Hogan Heh.

Q: How to hide the divide by zero exception in php ???

you_are_being_stubborn_about_your_division_shenanigans = false

Tim Stone

@TimPost Every time you try and suppress the division by zero warning, PHP should output an ASCII middle finger to the screen.

Tim Post

10:20 PM

@TimStone You need to foreach($finger as $birdie) and then test each one for true to see if the third one is raised.

Tim Stone

Brilliant.

badp's sockpuppet

@TimPost Obviously you can keep count of the finger number by incrementing a variable first thing inside the loop :)

I think I've seen something like that somewhere though.

Tim Post

@badpssockpuppet Yes, also it is a serious mistake to assume that PHP will always have five fingers.

mootinator

@TimPost jQuery can handle that.

badp's sockpuppet

<seriously>before you complain that Python has no for(;;) statement, consider the enumerate function.</seriously>

@mootinator #finger:nth(3) right??

mootinator

10:24 PM

Something like that.

badp's sockpuppet

see I used CSS 3 selectors, I must be right

Tim Post

@TimStone I think we've concluded that it's far, far easier for PHP to simply moon the developer rather than give them the middle finger.

Tim Stone

@badpssockpuppet Of course, because it's jQuery-compatible.

@TimPost Yes, if PHP crushed certain people with the weight of the moon we'd likely be better off.

badp's sockpuppet

Yeah, you could just say #finger + #finger + #finger but that would trigger all sorts of implementation specific bugs

@drachenstern for the same reasons why one would want to suppress divisions by zero errors

Tim Post

@badpssockpuppet No no no, it's simpler to do this.. $butt_cheeks = array('cheek_one_exposed' => true, 'cheek_two_exposed' => true); If both are true, you did something bad.

Thanks

drachenstern

But my point was, understand how it's laid out so that you understand what they're showing you on the screen. MSDN is a HUGE resource for a windows developer

Understanding how it's laid out will make finding stuff a lot easier.

mootinator

I thought going to google and typing site:msdn.microsoft.com [search] was what made finding stuff a lot easier.

drachenstern

nah, if you'll just put what you want in google that's fast enough. For instance: -> google.com -> ListView [enter] -> [click first link] -> done.

Moshe

@drachenstern Except that will return WPF and silverlight related results too...

@Moshe the beauty of C# says that you can port it easily once you redo the interface ;) ... but having done it in XAML you should be able to more easily port it from the phone to something else.

@Moshe seriously? ;p
