@Duga Ouch. First time over 1300.
 
That beta banner can really get misleading sometimes. Although design cannot be sped up, it would be nice if they could at least remove the "beta" from the top. :-/
 
@rolfl or anyone else with a Careers profile, isn't there a way to export your profile to a PDF or something? Am I missing a link somewhere?

Would you mind indicating which version of R# you are using? Hopefully this is a solution that works for R#8, though I'd prefer to do it in a way that sets a global setting added to the git commit so other team members pick up the policy as well (then no squabbling in code reviews, set the policy and done) — Kieran Coulter 1 min ago

A: BaseTableViewController with pull to refresh and auto load more

nhgrifFirst and foremost, I have to point you to NS_REQUIRES_SUPER. This macro should be used with your methods which actually implement some logic.

Quote of the day:
> Don't document [comment] bad code, rewrite it.
 
So, today I successfully updated a client.
And someone requested my resume.
 
@Duga I will take a look at the C# ones!
@nhgrif nice
 
@Duga 1304 as soon as someone upvotes the one I just linked.
And I know you clowns got votes--we just reloaded.
@sᴉɔuɐɹɥԀ How current is this theory?
 
@nhgrif Done.
 
12:59 AM
@nhgrif Not completely sure. Looks like Hawkings recorded the talk in 2012, so not very old at all
 
Ah.
Well, giving that it's far from my area of expertise and it's not important for me to be right (and I'd never try to tell this to anyone as if it were the truth), but I like the idea that Neil deGrasse Tyson proposed in Cosmos...
That potentially, there's an entire galaxy within the center of a black hole.
that galaxy, of course, having its own black holes with galaxy at their centers...
 
Would that be... recursion?
 
Yes.
 
Seems like a bit of an unsolvable riddle, if DeGrasse Tyson was right
 
Well, yes and no....
 
1:04 AM
(which he very well could be)
 
It's not the same galaxy.
And I don't know if its his theory or not.
I mean, it's not the same galaxy, and may not even look the same, etc.
There wouldn't be a Milky Way in the other galaxy necessarily.
 
I think of him as more of a science educator than researcher, as opposed to Hawkings. Nothing wrong with the guy, I love his remake of Cosmos
 
Yes.
Centuries from now, no one will know Neil deGrasse Tyson most likely. But he's probably the most important living person for science today.
 
He's certainly up there, I agree.
 
Hawkings is building on the research of his predecessors, and most of the consequences of his current work really won't be fully realized until decades or centuries from now.
 
1:08 AM
Well-stated ^
 
In some ways, it's probably slightly amazing that we even actually know of him today.

> The average developer is 28.9 years old. He or she was born in April 1986, just as the Chernobyl meltdown was taking place.
I was born January '86.
 
@nhgrif Guess you're a bit older than the average bear developer!
 
Just slightly older than the average Stack Overflow user.
These are results from a SO poll.
 
Was born in Dec 1983 so I guess that puts me right in that 31 y.o. bracket which is right at the U.S. average age
 
> Upon closer examination of the data, a trend emerges: Developers increasingly prefer spaces as they gain experience. Stack Overflow reputation correlates with a preference for spaces, too: users who have 10,000 rep or more prefer spaces to tabs at a ratio of 3 to 1.
 
1:59 AM
I'm ordinary like that :)
 
So... read that... and then realize that of those polled, 45% prefer tabs, 33.6% prefer spaces... which is why there are so many bad questions on Stack Overflow.
 
> 1940s - Various "computers" are "programmed" using direct wiring and switches. Engineers do this in order to avoid the tabs vs spaces debate.
 
The correct answer to tabs vs spaces is to use Xcode.
You press tab. It inserts correct number of spaces.
You press backspace, it backspaces correct number of spaces as if they were tabs.
 
Eclipse does that too. I think Netbeans too
 
Apparently I need a raise.

Of course, miniAudicle doesn't. Groan. Cool programming language, bad tools.

Those are averages.
 
> In truth, we don't know that there's any causal link between reputation and compensation, but indulge us for a moment. If rep equals money, you could get a 10% raise just by going from 1 to 100 rep on Stack Overflow. If rep equals money, you would only reach average developer status once you earned between 200-499 rep.
(I'm pretty sure that's a typo which should read 500-4,999 rep at the end)
wow, lol...

About the i variable. I happen to know that it is faster to do two get(i) on an array list, than it is to do the sublist of an ArrayList.

    return n * Factorial(n - 1);

Does anyone else see it?
Where's the bug?
 
Factorial(-1)
static unsigned long Factorial(unsigned long n)
Or find some resolution for negative numbers in the logic.
 
@RubberDuck what is your input value of n?
I hope it is less than.....20

Yeah, there is also overflow.
 
I hadn't even considered the overflow to be honest.
I just spotted the infinite loop.
 
12:27 PM
It's not an infinite loop. It's infinite recursion.
 
Yeah yeah. You're right.
For some reason, recursion is a loop in my mind.
 
1. Understanding a loop has two steps.
2. See step one.

To understand recursion, you must first understand recursion.

If your code compiles and runs correctly, and you just want comments on it, then it would be easiest if you go to the Code Review site and post this again. Be sure to check the tour on that site for posting guidelines. You will at least want to remove your second question for the code review. Then you can either delete this question, or take out your question about reviewing the code. — yellowantphil 41 secs ago

I am running 7 queries to fill 7 comboboxes any waiting till they're all filled before any are enabled.
Hmm, let me try something. Sometimes I need stuff selected.
 
the easiest remains to include an empty selection in your data source...
 
Yes, but it's selecting the row after that...
If the query returns 1 row, I must select that. If the user had a row selected before the data reloads, the item with that ID must be reselected.
Each selection reruns queries and limits the choices of the other 6 fields.
I'm finished with the hard 99%. Now I just have to make the harder 99% work.
