@JeroenVannevel I must say that the Go language seems to look funky

What aws your experience programming in it?

Jeroen Vannevel

8:20 PM

the 20 different ways to declare a variable is a little puzzling sometimes but I think I got the hang of it now

overall it feels.. okay

There's some behind the scenes magic I haven't uncovered yet

but I didn't follow a proper introduction either

skiwi

Hmm okay, that tells me like close to nothing, but you are at least not bashing it into the ground

Jeroen Vannevel

give it a shot, you can get something working really quickly

skiwi

No real interest right now as I'm busy learning Python as well :P

Perhaps... some day

That magical day on which you will do all your planned work

nhgrif

Go is not magic. You must be thinking of Swift.

"Great Answer" badge on SOMeta.

Mast

Swift is arcane.

nhgrif

8:32 PM

Arcane?

Mast

Yea, like Perl, but worse

nhgrif

Do you know what Swift is?

Mast

iOS language

the .NET of Apple, right?

nhgrif

Never mind ... I just looked up definition of arcane... Wasn't quite what I thought.

It's not the .NET of Apple.

Foundation is the .NET of Apple.

Mast

Oh

Never heard of Foundation

nhgrif

8:36 PM

That's because before Swift, it was only one language... Objective-C

Mast

So, they split it up?

nhgrif

8:52 PM

No.

They just created a new language (like 10 months ago it was announced).

Mast

Thanks for the heads up :)

nhgrif

But the new language (Swift) uses Foundation (and all the other base frameworks that Objective-C uses for iOS/OS X applications).

So, Foundation/Cocoa/Cocoa Touch/etc, are the frameworks (.NET is the framework). Objective-C & Swift are the languages. (VB, C# are the languages)

So also, in the Xcode vs Visual Studio.... Visual Studio has lots of source control plugins, but they're just that, plugins. Xcode comes with built-in git support.

Mast

doesn't VS have git support nowadays as well?

you can either throw your code on Teamfounndation (or whatever it's called), or make a git repo

Automagically

nhgrif

I'm not certain. I haven't used the newest full version of Visual Studio. Visual Studio... have to pay for the full versions.

Xcode completely free (as long as you have a Mac)

Mast

Latest I used was 2012

Oh, 2013

Mat's Mug

8:59 PM

@nhgrif you can use VS Community (== Pro edition) for free if you're a freelancer or if you're writing code for open-source projects.

Rubberduck is written with VSC2013

nhgrif

Yes, but is that the fullest full version?

Mast

There's usually an Express, Professional and Ultimate

Express is free, Pro is considered full and Ultimate has bonus

But I'm not up to date with their terminology

nhgrif

It's kind of the pain about VS though. At work we haven't upgraded lately because we'd have to buy a whole new set of licenses (we're not writing open-source code).

Jeroen Vannevel

Express is gone

Community is the free version now which is equal to Professional

Mast

...

Microsoft and it's terminological nightmares

SirPython

9:03 PM

@nhgrif I don't know Python that much, actually.

nhgrif

This is all built into Xcode.

SirPython

Wow. That's pretty fancy.

Mast

So, top with graphics?

nhgrif

Mast

It looks great, good tools to convince a manager

nhgrif

9:11 PM

It's not just graphics. It's live graphs demonstrating your application's active CPU usage, RAM usage, Disk IO usage, Network IO usage.

And mapping it over time.

And showing where all this stuff is coming from.

Mast

that's neat

SirPython

These remind me of some features like this I saw in a video about Swift Playground

nhgrif

Swift playground is way cooler than all of this.

SirPython

Isn't Swift Playground an add-on of XCode?

nhgrif

Swift Playground is built in to Xcode. It's not an add-on. It's just a different project type.

You don't download anything extra. You just update to Xcode 6.0 or later.

Mast

9:13 PM

If I ever get my hands on a Mac, I'll try it

nhgrif

Playground is a little buggy still, but it's magic, so yeah..

A: Does anyone still use [goto] in C# and if so why?

There are some (rare) cases where goto can actually improve readability. In fact, the documentation you linked to lists two examples: A common use of goto is to transfer control to a specific switch-case label or the default label in a switch statement. The goto statement is also useful ...

Normally I'd try to refactor this to put the loops in a separate method which I could just return from... — Jon Skeet Jul 1 '11 at 9:00

@ericlippert some of us over at http://codereview.stackexchange.com/ were wondering if you've written anything regarding why `goto` still exists in C#.

    for (name in friends) {

        } else {
            console.log("No match found for " + name);
        }
    }
}

search("Steve");

> No match found for bill
No match found for steve

Tried a few other ways, and either I get invalid references, or it just prints out all data for each index

Anyone got a clue what this beginner is missing?

Jeroen Vannevel

name name name name

You're hiding your parameter by re-declaring (using?) it again in your for

that's bound to blow something up

and your friends thing doesn't look right either

if friends is a collection of friend objects, then friends.firstName can't work

use for(friend in friends) and if(friend.firstName === 'blaat')

I've got no clue where key suddenly comes from either

@RubberDuck the Crocodile

is there something happening to SSIS that I should know about?

RubberDuck

@Lyle'sMug Not that I've heard. Why?

Lyle's Mug

someone at work here was saying something about it not being available or something with the newer SQL Server versions or something, then they said something about BIDS

sᴉɔuɐɹɥԀ

for (name in friends) is not re-declaring, if I did for (var name in friends) then it would re-declare... I think

@JeroenVannevel OK I'll try that when I get home, because it's TTQW!

Jeroen Vannevel

10:08 PM

@sᴉɔuɐɹɥԀ if do use for(name in friends) then you create a loop where each iteration i taken element i from that collection and stores it in a temporary variable called name

nhgrif

You are redeclaring

Jeroen Vannevel

Try to log name in your loop and you'll notice it gets the values of the names in the collection -- not the value you passed as argument

rolfl

@JeroenVannevel I disagree.

RubberDuck

@Lyle'sMug AFAIK they just changed the name..... again.

@JeroenVannevel I believe that should be var friend, as not to create or modify (a) global variable(s).
