does it return a NaN value?
 
No, it returns 0.

wait no...
Maybe this is just Xcode 6, but now it gives me a warning saying division by 0 is undefined

Oh, I found one!
Unfortunately, I don't want to get the serial upvote system after you: I'll stick that answer in my back pocket for later.

@nhgrif Are you not a fan of Yoda conditionals?
 
No.
The only time I ever do that is in SQL
 
yoda conditionals lead to anger, anger leads to hate, and hate leads to the dark side

@nhgrif What is Boolean? I thought it was the ObjC true/false type.
Or, is there some NSBoolean I don't know about...

I don't know what Boolean is exactly.
NSNumber *someBool = [NSNumber numberWithBool:YES];

A: Is there any difference between BOOL and Boolean in Objective-C?

jshierBoolean is an old Carbon keyword (historic Mac type), defined as an unsigned char. BOOL is an Objective-C type defined as signed char. bool is a defined version of the _Bool standard C type. It's defined as an int. Use BOOL.

 
hmm, I would have probably done IF EXISTS instead of IF 1 = count
nm exactly one
my attention is slightly divided :)
 
Yeah.
That's why I did 1 and not 0
Because IF NOT EXISTS
I almost never have to do that though.
Actually, I take that back.
I do that sort of regularly.
But the query is a lot simpler than that hyperbole
 
I don't think I've ever had to do that - what do you use it for?
 
@nhgrif So does that mean there isn't another one coming?

Q: CRTP object counter to track accidental singleton instantiation

It is a header only class: SingleInstanceType.hpp: // ====================================================================================...

 
@syb0rg Correct. I was going to explain to you what a normal init method should look like... but there's no possible way I can think of right now to make this method fit the form of a normal init method.
@DanLyons I'm developing an app which does lots of ERP things. Part of what this does is provide the functionality for scanning barcodes. The actual barcode scanned could be anything, but if I assume it's a particular field in the database, I need to differentiate between when the scanned barcode matches exactly, and when it doesn't.

It is a header only class: SingleInstanceType.hpp: // ====================================================================================...

So, I guess singletons in C++ are a lot different... and you have to know when your class is a singleton and call a non-constructor method to get the reference to the singleton?

so I'm reviewing the source code in the book and it just hurts
declaring an array, casting object to array, storing it in a variable, then testing if the variable is not null
... for checking if a regular expression matches a piece of text
Hint: there is a built-in test method, which returns a boolean
      protected function recourse( str : String , count : uint = 0 ) : Boolean
      {
         var tmpAr : Array;
         var expressionString : String = (count < profanityAr.length - 1) ? '\\b' + profanityAr[count] + '\\b' : profanityAr[count]

         var regExp : RegExp = new RegExp( expressionString , 'gix' )
         tmpAr = (regExp.exec( str ));
         if (tmpAr != null)
         {
            return true
         }
         else
         {
            if (count < profanityAr.length - 1)
find tze mistakes
I expected better from code in books =/
 
what language is that?
 
ActionScript 3
 
tmpAr, wtf?
 
Wow, that looks a bit like Swift.
 
tempArray is hard to type huh?
 
12:13 PM
temporaryArray...?
 
- tmpAr is not needed, because the data from it is never read
- regExp.exec is unneeded, the only thing that matters is whether you have any hits, so use regExp.test instead
- regExp.test returns a boolean, assigning it to a separate value is unneeded
- else with only a single if in its body - use else if instead, saves you a level of indentation AND two lines
- why is it recursive? Rewrite as iterative instead
oh and of course it's missing semi colons

"Help your cat get back in the school routine" and the email is trying to sell you cat toys.
As if my cats give a shit whether or not I'm home.
 
my cats have the magical ability to stare at a wall with their eyes open for hours
and not the "from a distance" kind
< 30 cm (1 ft)
 
Occasionally, I have cat toys delivered to my house. It's a weird ordeal ordering cat toys. You pay for the packing material such as books, or whatever, and they just give you the box for free.
 
So uh
 
But if I were to be going back to school, I'd actually be home a lot more often than I am now, in which case, I could sell my extra cat toys off to other people.
 
Does this happen often, that programming books are written by writers and not by programmers?
 
12:19 PM
I don't think so, but there are editors.
But usually editors don't touch the code snippets.
 
... ahhh...
 
With that said though, I'd be willing to be that more people writing programming books are programming educators moreso than working professional programmers.
 
oh crap this was example #1 I still have 5 more to go in this chapter
 
My mom has a Masters degree in Civil Engineering. Civil Engineers are the people who do roads and bridges and such. My dad only has a high school degree but he has worked in bridge construction since he was 18 basically. So my mom has just about all the formal education and theory on the topic possible. My dad meanwhile has basically all of the real world practical application of the topic possible. My mom generally learns more new things from my dad than the other way.
My dad might not quite understand all the theory and math behind all of it, but he knows how to do it as well as anyone else.
And my mom is very intelligent.
 
"Consider these sections of an ActionScript 3.0 web site: Portfolio, News, About You, Home, and Contact."
 
12:24 PM
But consider you were trying to get a book about practical bridge construction. It'd probably be more useful if my dad wrote it. But people like my dad don't have time for writing books, and usually not an interest in writing books either. So more likely, you're getting a book which was written by my mom. Which would be great if you're interested in the math and theories and bigger picture comments.

Who ever came up with the "Reticulating Splines" idea when they were working on SC2k is a genius and quite the trendsetter.
 
12:28 PM
what does that mean
 
I'm afraid this user is not getting the point of CR
 
Reticulating Splines?
In the 90s when the phrase was inventroduced, it meant nothing, along with all the other silly phrases the SC2k loading screen showed you.
But in SC2k, it was really subtle. The phrases the loading screen showed you sounded technical enough, but they were all relatively meaningless.
I think in "The Sims" it became more obvious that the phrases were intended to be funny, but "Reticulating Splines" remained in the phrases.
Since then, it's appeared in every Sims and SimCity game as well as games outside of Maxis. It was always a joke.
 
that guy
that guy just edits stuff all day
I think he likes reading?
 
Then, a couple years ago, while working on the new SimCity game, Ocean Quigly, who worked on several of the Sims games as well as SC3k and SC4, tried inventing an actual technical definition out of "reticulating splines"
> SimCity 2000 was the first Sim game to feature the semi-nonsensical phrase "Reticulating Splines", which means to make a network of splines. Will Wright has stated in an interview that the game does not actually reticulate splines when generating terrain, and he just inserted the phrase because it "sounded cool".[citation needed] The phrase has since been featured in SimCopter, SimCity 4, The Sims, The Sims 2, Spore, The Sims 3, The Sims Social and SimCity Social...
> It is also used in the web-based game Glitch, the popular video game Minecraft (as a title screen splash text), the music service Turntable.fm, the free online education sites khanacademy.org and grovo.com, the operating system Ubuntu, the photo-sharing sites Flickr and SnapJoy, the Humble Indie Bundle Android app, when generating certain reports in SEOmoz, when preparing the game collection analysis in Raptr, and the free-to-play game HAWKEN.

Q: Probabilities using 3d10 as 1d1000

FrankI'm trying to use anydice to figure out the probabilities of the various values of 1d1000 rolled on 3d10. I want to know stuff like "what's the chance of rolling 900 or higher? How about 950 or higher?" I'm not sure how to script anydice to give me this information if it's actually possible. ...

This question is claiming that 1d1000 has the same odds as 3d10 for any given number.
I'm not sure how that's possible.
 
Aren't the odds for 1 always different or even 0 on one of them?
 
1d1000 = a one-thousand sided die
3d100 = three one-hundred sided die
The numbers have to either go 0-999 or 1-1000
Or, 0-9, or 1-10
Wait, you multiply the numbers you rolled on the 10 sided dice?
but 10*10*9 = 990
so you can't roll anything between 990 and 1000 on 3d10
 
I think they even use it differently
to me it sounded like you roll 3 dice range [1, 10]
then you calculate result as (d1 * 10^2) + (d2 * 10^1) + (d3 * 10^0)
 
Yeah, that'd make sense.
But then you either can't roll 0 in the hundreds place, or you can't roll 10
 
I think it has to be 0-9 then
 
12:51 PM
Then you can't roll 1000
Wait
Here's the formula
((1d10 - 1) * 10^2) + ((1d10 - 1) * 10^1) + (1d10 * 10^0)
So the first two are 0-9
The last one is 1-10
Because if you roll 9 (900) + 9 (90) + 10, that's 1000
 
that sounds overly complicated... but I agree
 
Or if you roll 1 (0) + 1 (0) + 1 (1), that's one.
I am curious as to the mathematical theory on whether or not the distribution truly is identical.
 
nhgrif
 
Yes?
 
roll 3 digits
then +1
or
 
12:58 PM
The die are label 1-10
 
random.nextInt(1000)
+1
 
I think they might count 10 as zero for the first two die
 
yeah
that's what I mean
 
But not on the last die
 
err then they are stupid
 
12:59 PM
They use three different colored die
 
kk
 
And actually, there are probably die label 0-9
 
if you can get 1099
then something went wrong
 
You can't...
Three die, three different colors. Before they're rolled, each one is known what die it counts as
You have a hundreds die, a tens die, and a ones die
And these posts talk about "percentile die", so they probably are labeled 0-9
 
...
 
1:00 PM
These would be used for the predetermined hundreds and tens rolls.
 
using 1x 1-10 die and 2x 0-9 die to get 1-1000:
 
Yes.
 
hundreds = 0-9
tens = 0-9
 
Right
 
ones = 1-10
 
1:01 PM
Right.
 
if ones = 10, ones = 0, +1 to tens.
 
Yes.
 
if tens = 10, tens = 0, +1 to hundreds.
that's how you get 1-1000.
 
scroll up to where I said "Here's the formula"
 
so you can't roll anything between 990 and 1000 on 3d10
is false
 
1:02 PM
Yes you can.
Err, right
 
well you just said that
 
I figured that out.
