@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

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
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?
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
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.

Hey what's the * for in those declarations?

> 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.
2:04 AM
Of course, miniAudicle doesn't. Groan. Cool programming language, bad tools.

Damn, developers make that much? I'm clearly in the wrong field, if that's the case.
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)

Q: Transitions from one element to another

user69894I am implementing an automated help function in my code. It is simply a few bubbles that pop up with some text in them. I use d3 to select one bubble, display it for a short time, and then select another bubble and display that one. It works, but I don't like the shape the code is taking. Am I ap...

@meager I think its fine here, it's not really code review, its a d3 technical question. — Cool Blue 1 min ago

@RubberDuck why are you doing homework? Are you a student?
@nhgrif The boss wants me to take a C# class.
rolls eyes
Do you know vb.net?
Don't rolls eyes ... it will be good for you.
1:40 PM
If you know vb.net, you can teach yourself c# easily and let boss pay you what he would've paid for class.
Maybe it will be later in the course, but right now it's data types, loops, conditionals...
@nhgrif Unfortunately it's not like that. HR wants to see everyone "improving themselves".
Nevermind that I have a pretty good grip on C# already.
@Mat'sMug Frakken stupid VBA!
@coolblue it seems to be a working implementation, that the author is asking for critiques on. That's a code review. — meagar 1 min ago
if you know JavaScript and VB.NET you should be okay just winging it, @RubberDuck. but hey free training! DO IT!
@RubberDuck Easy then!
1:48 PM
soak it all in, I wouldn't mind a refresher. right now I am trying to teach myself MVC though
@Mat'sMug Yeah. I actually have my first week's work done, so back to RD now.

@Lyle'sMug 28, and a bump.
It doesn't work because you basically have the mistake in it. SO is not the place for code reviewing — Andremoniy 24 secs ago
Your counts may be lower ....
i'm not asking for code reviewing I want to know what the mistake is + if I can do anything to fix it or if anyone willing to give me a hand with this, thanks for the thumbs down. — Hava Nasar 1 min ago
@Lyle'sMug - For even-size rows you would not get an alternating pattern - all rows would start with the same colour and you would get stripes, not checkerboard. — rolfl ♦ 5 mins ago
I see
@Andremoniy well the place for code review questions would be on Code Review, but if the code doesn't work as intended, it's not ready for peer review, it's off-topic on CR and on-topic on SO. Upvoted. — Mat's Mug 50 secs ago
@JS1 I think you're right; I'm still quite new at this programming thing so I make mistakes all the time :)

Q: Torus Maze Generator

@FISOCPP: Done. I needed some brain/coding exercise. Just be aware that if this is homework, as seems likely, then you learn less by asking for solutions rather than doing it yourself and asking for code review. — Cheers and hth. - Alf 18 secs ago

have better code review process as well as develop some internal coding best practices. also encourage your coders as well as your self to debug your code and to not check in code that has compiler warnings ... that's a good place to start I would think — MethodMan 12 secs ago

+1 for ReSharper. In our team, you are not allowed to submit your code if there are any reSharper warnings. The code review would get rejected. — Andrey 58 secs ago
3:20 PM
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

So... When I change a combo box from disabled to enabled, it automatically selects a row. Is this normal and can I prevent it?
Use COBOL, no such problems in that language ^^^ ;-)
Use COBOL, have no issues with advanced concepts anymore!
Ok, thanks for the answer. I will mark it as accepted in 5 minutes.

alanbuchananI am going through the CodingBat exercises for Java.

cmbBox.datasource = aDataTable
then you can probably explicitly set the selecteditem to null
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.
