Look at the bots profile, it says there

@Duga Thanks!

Yep

I wrote a C# regex.

I think its terrible, though.

How are these bots created? Does someone just create another account, hook up some code, and send 'em to the chat room?

@SirPython Basically, though users need a certain amount of rep to post to a chat room

12:03 AM

Is the code replicating key-strokes for the bot? Or, is there an API for this?

Also, their use was 'vetted' by the moderators too in this room in particular.

Does anyone have any ideas as to how I could make some code such as this so that I could record for a theorhetical infinite amount of time? Right now it's bound by a time limit.

There's an API of sorts.

@Phrancis did you manage to make prettify work eventually?

12:05 AM

Not quite the way I want to, yet

There's missing tags in there, @Phrancis

end tag, and start-tags-with-attributes

</script> not an end tag?

If that is supposed to by HTML, you should put it in <body> and <head> tags.

That for loop is still wrong, right?

@Simon - by the way, I edited the 'about-me' for Duga here: chat.stackexchange.com/users/125580/duga

12:08 AM

Or is that how JS works?

@nhgrif ^^that

@Phrancis I'm not sure if this is intentional, but you declared myInt with var in two places - you should only have it once, as your editor/browser might raise a error/warning saying that myInt is already defined.

Q: is there a way to optimise my code for faster executing?

0

based on this guidlines i optimised Bresenhams line algorithm, now it fits for all kinds of line cases like images a, b, c, d, e, f, g, h shows in that guidlines. so here is what i did: this is my test.txt input file for all line cases: x1 y1 x2 y2 10 10 50 10 10 20 50 20 60 10 60 50 70 60 70...

@rolfl thanks :)

@rolfl are you sick of @Duga?

Ok, I haven't ran it or anything, only intended to be example code

12:10 AM

@SimonAndréForsberg No, he's behaving fine.

@rolfl It's a she! And good.

var myString = "Hello, World!";
var myInt = 42;

function helloWorld(world) {
    for (myInt >= 0; --myInt) {
        alert(myString);
    }
}

Better? ;p

@Phrancis - the loop variable should be assigned a value: for (var myInt = 10; ....) ...

Oh ok let me refactor ;P

for (var myInt = 10; myInt >= 0; myInt--) { ....

12:12 AM

var myString = "Hello, World!";
var myInt = 42;

function helloWorld(world) {
    for (i = 0; &lt;= myInt; i++) {
        alert(myString);
    }
}

@Hosch250 is there a reason you are using \p{N} for digits instead of \d?

@DanLyons No, except Expresso told me that was the code for numbers.

if you're only concerned with non-globalized 0-9, you can just use \d

I'm off to go do something else. See you guys/gals later.

@SirPython Ciao!

12:13 AM

you may want to take a look at the MSDN page: msdn.microsoft.com/en-us/library/az24scfc%28v=vs.110%29.aspx

OK.

Do you all like the line numbers?

I go back to it pretty regularly when I do regex because I do it infrequent enough I never remember it all :P

@Phrancis Yes.

err....

12:14 AM

@DanLyons I actually had a different MSDN page open, but it didn't list the code.

for (; myInt >= 0; --myInt)

I saved this one.

empty initialization statement since myInt is already declared and initialized.

Or, as I stated earlier, this would work:

while (--myInt >= 0)

@rolfl I think this is everything:

<html><body style="font-size: 12pt;">
/* This is
 * a block
 * comment
 */

<script type="text/javascript">
// This is a comment

var myString = "Hello, World!";
var myInt = 42;

function helloWorld(world) {
    for (i = 0; i <= myInt; i++) {
        alert(myString);
    }
}
</script>
<style>
    p { color: pink }
    b { color: blue }
    u { color: "umber" }
</style>
</body></html>

Wow, this skin is horrible... Can you imagine if your IDE displayed like that?

I'm amazed someone would even take the time to make this

@SirPython Hope we see you back!

Hmmm, so my problem is with the maxFrameIndex, but if I was recording for an infinite amount of time then I wouldn't have a said maxFrameIndex...

12:29 AM

thanks Santa!

You can't record for an infinite amount of time...

@nhgrif Yes, I know... but I need to be able to do so (in theory anyways)

12:49 AM

Anybody around who knows C#?

@Hosch250 are you here?

Yup.

Just got back.

Do you know how to re-raise a winform event?

Never used winform.

Like, I want to delegate the event handler to my controller, but I need to register the event handler to begin with.

Could you provide a bit more detail? I might be able to figure it out.

12:51 AM

Ahhhh nevermind. Thanks.

I'm having difficulty explaining, which is probably why I'm having trouble searching for an answer to begin with...

Let me try. One sec.

Okay, so in my controller, I register this event.

_view.AddMarker += AddMarker;

Are you RubberDucking yourself?

5

Yes?

Which is defined in my view like this.

public event EventHandler AddMarker;

@RubberDuck the only class that can raise an event, is the class that defines that event

So, I think what you probably need to do is put that code in a method.

Then, call _view.AddMarker += () => { methodCall(); };

12:53 AM

@Mat'sMug I want to still let the view raise it, I just want the controller to react to it.

That is what I do when I need to check something that is raised by an event.

Or do I have this all wrong?

@Hosch250 Anonymous methods will work, but they make it harder than needs to be, to unregister a handler

I do this in WPF:

        public MainPage()
        {
            this.InitializeComponent();
            SettingsPane.GetForCurrentView().CommandsRequested += OnCommandsRequested;

            this.DataContext = Data;

            this.SizeChanged += (s, args) =>
            {
                PageSizeChanged();
            };
        }

        void PageSizeChanged()
        {
            String state = (mainPage.ActualWidth > 750) ? "PrimaryView" : "Snapped";
            VisualStateManager.GoToState(this, state, false);

Not sure about WinForms.

My brother sent me this: Amazon travel mug review

12:56 AM

Okay, so what I really think I want to do is pass a delegate from the controller into the view to be registered...

I'm talking nonsense aren't I?

An event is a special kind of multicast delegate

Figure out what you want to do (usually the hard part), then do it.

3

This is what I really want to replace.

this.tokenListBox.SelectedIndexChanged += new System.EventHandler(this.tokenListBox_SelectedIndexChanged);

That was built by the designer and it's in my view. I want to keep that action in the controller.

Am I making sense yet?

And you want to be able to call new System.EventHandler(this.tokenListBox_SelectedIndexChanged); from many places?

I don't think I'm helping.

No. I want to register a method from the controller as the event handler.

1:04 AM

So you want to have a method do the work being done in new System.EventHandler(this.tokenListBox_SelectedIndexChanged);?

Or you want to call a method instead of new System.EventHandler(this.tokenListBox_SelectedIndexChanged);?

Does the tokenListBox have a SelectionChanged call?

I want to replace this.tokenListBox_SelectedIndexChanged with a method from the controller. Which I'm not sure makes any sense at this point.

SelectionChanged is the event delegate in the view.

I'm not getting it.

I'm not familiar with WinForms terminology.

So where/what is the controller?

Is that the code-behind?

If so, then you probably need to call something like _view.AddMarker += (sender, e) => { methodCall(); };

Then you can call methodCall() wherever you want.

@RubberDuck No. SelectionChanged is an event of a ListBox - if you want the view to have a SelectedTokenChanged event, then make the handler for the ListBox event fire up such an event!

@Mat'sMug That's exactly what I'm not quite getting.

@RubberDuck Check out my "event-tossing UI" post - no review pointed out it was a bad approach ;)

discussion bug wording voting-limits

@Mat'sMug, sorry this is not my question so I don't know it's details but quite curious to understand it. So SelectedTokenChanged is a custom event? would you be able to give me an example of this? And I honestly don't know what do you mean by belonging to the view itself. Does this mean this event isn't related to listbox but the view ?

1:26 AM

The idea being that the controller needs to know that something happened in the view that needs to be acted upon - but the controller can't listen to control events directly, because it would break encapsulation and tie the controller to the view

Perhaps it has happened for someone other than me!

@Donald.McLean @rolfl Are we being watched?

@SimonAndréForsberg I get random votes on that answer every now and then

emmmm... getting interesting

@SimonAndréForsberg In C#, you just do [List.Count - 1] instead of [-1].

Not that different, but different...

@Hosch250 where did I say [-1] ? Sounds like C# matches Java there.

1:29 AM

> Feature-request:
> As you re-implemented the Substring method, perhaps consider PHP's implementation which has support for negative parameters. It is one of the few things I actually miss from PHP.

So I make an event that says "SomethingHappened" and raise it when user clicks a button, or whatever - the controller doesn't know about controls on the view, only that the view is saying "SomethingHappened"

PHP allows negative values.

@SimonAndréForsberg Have not yet watched last week's ... noone answered me on whether it was a part-1-of-2...

See ya.

Good night @sim

@Hosch250 on hold, until the PTB decide otherwise

OK.

@Mat'sMug I think me not grasping the whole idea properly comes from not being totally familiar with the glossary. I am familiar with the Control which can be, say, a button or listView in this case (if I am right). but not sure about controller and can't relate to the whole view as an entity. and I kinda have a feeling that we want to implement something like We wanna know something happened when something happened is happened.

but not sure we as me, is a Controller or view or even something else... :)

Heard of MVC?

1:36 AM

and also if possible, can you point me toward a reference that I can read about the concept of controller then you don't need to explain the whole thing. :)

Oh... that controller

D'oh!

I forgot to change the parent form to use the controller instead of the view.

3:31 AM

I think I found a little easier way for now

I just average a sample set, and if it is greater than 0.000400 then it will save the recording

It still catches little bits of louder noise here and there, but I can make it so that I only save audio clips of a meaningful length

that's probably easier, yeah

it won't be as effective when the sound is generally lower though, right?

I may need to fine tune the threshold a bit, but for now it should be okay while I finish implementing the code

the treshold will be lower then and vice versa when the input sound is louder than usual

@JeroenVannevel Yeah, that's where I'll probably need to implement your clustering idea
