@SimonAndréForsberg
You could unregister the click handler, and then re-register it when you want to re-enable the event handling: textBox1.TextChanged -= textBox1_TextChanged; to disable the event, and then textBox1.TextChanged += textBox1_TextChanged; to reinstate it. — Mat's Mug 14 secs ago
does Java have an equivalent?
 
@Mat'sMug
Depends on the framework, removeClickListener or similar do tend to exist
 
then...
 
I think that often in such situations though, there's a 'design' problem somewhere.
 
true. hence I'd like more context too, to reopen that one :)
 
@nhgrif I just marked your answer as best for my latest question, and I had marked a best answer for my previous question a couple days ago
 
12:13 AM
the adding/removing of listener could be factored into a little function.. how dirty is that?
 
@Mat'sMug Can't answer that without more context :)
 
how can this work?
 
12:45 AM
is this CTE correct?
@SimonAndréForsberg thanks for linking your SudokuSharp challenge, I've been getting passive/random +10's ever since! +40 so far this week!
 
@Mat'sMug Linking it twice paid off then ;)
 
haha yeah
seriously though, I'm not all too familiar with CTE's, if anyone could check it out and downvote as appropriate and comment to help me fix it if it's wrong, would be great! :)
 
I don't even know what a CTE is!
 
lol!
it's pretty quiet tonight
 
I "lost" 80 rep yesterday
And I've already earned 45 rep today
 
12:53 AM
Why the hell would you group by a date converted into a varchar instead of just grouping by the date?
 
It's kinda.... sad/depressing/strange/fill-in-the-blank though that my highest upvoted question right now is... drumroll please!

Q: FizzBuzz in Brainfuck

Simon André ForsbergInspired a bit by a previous Brainfuck question and the recent fizzbuzz invasion, I decided to make FizzBuzz in Brainfuck. The code is entirely my own, except for the inclusion of the Printing a number algorithm that I found on StackOverflow. My code is divided into several parts. Setup Const...

 
haha
 
And also, why would you order by the date converted to varchar instead of just ordering by the date?
 
@nhgrif in T-SQL you can't GROUP BY SomeDate if SomeDate isn't part of the SELECT...
 
I wonder how many upvotes I would get for that Sudoku Solver in BF we've been talking about @Mat'sMug :)
 
12:54 AM
It is part of the select though.
 
it's not. CONVERT(varchar, effectivedate, 102) is.
 
SELECT
        ROW_NUMBER() OVER(ORDER BY (CONVERT(varchar, effectivedate, 102)) ASC) Rn,
        CONVERT(varchar, **effectivedate**, 102) effectivedate,
        SUM(EuroCurrentBalance/1000000) TotalArrears,
        SUM(CASE WHEN Multiplier > 2 THEN EuroCurrentBalance/1000000 ELSE 0 END) NPLs,
        CASE WHEN ROW_NUMBER() OVER(ORDER BY (CONVERT(varchar, effectivedate, 102)) ASC) = 1 THEN 0 ELSE SUM(EuroCurrentBalance/1000000) - (LAG(SUM(EuroCurrentBalance/1000000),1,0) OVER (ORDER BY (CONVERT(varchar, effectivedate, 102)))) END MonthlyChange
 
it's passed to a function, the result of that function is part of the select.
so the group by must be by the result of that function.
lame, I know
or did that change in SQL2012?
(starts SSMS)
oh crap
USE [AdventureWorks2012]
GO

SELECT
      [Title]
      ,convert(varchar,[ModifiedDate],102) dt
  FROM [Person].[Person]
  group by title, ModifiedDate
GO
^^ works
@nhgrif thanks mate, edited - and I learned something today! :)
I'm pretty sure that doesn't work in SQL Server 2005/2008 though.. too bad I don't have access to it anymore
@rolfl would know that, right?
 
> Of course, Americans could also probably use a little remedial geography instruction, if a poll conducted by the Washington Post in April is any indication.

Only 16% of respondents correctly located Ukraine on a map, and more than a hundred of the 2,066 participants seemed to think the Eastern European country was somewhere near Greenland or, ironically enough, Canada.
WTF, seriously America?
 
they haven't played enough Risk
and yeah WTF... where do they think Russia is??
 
1:09 AM
@Mat'sMug Brazil? Alaska?
 
I'd hope they know where Alaska is... ...
how's your BF sudoku solver coming along?
 
@Mat'sMug I don't think 3:10 am is the best time to start on that
 
isn't it? -.-
 
BTW:

A: What are the advantages of graduation?

Mat's MugAnother "advantage" that no one mentioned yet: Beta sites aren't listed at the bottom of EVERY PAGE ON STACK EXCHANGE!

 
Don't you guys get bored of coding? :P
 
only when I'm sleeping... and not dreaming in code :)
 
@Anirudh No offense but... are you nuts?
Do you ever get bored of having fun?
 
1:28 AM
True Simon
I was just kidding
 
@Anirudh congrats BTW, your open/closed doors question went hot!
 
Well, honestly @Anirudh, I don't get bored but I can get discouraged some times.
 
Ahh yeah!! Thanks Mat...It actually was a good question that was asked in an interview to a firend
*friend
I knew attempted it using brute force but there had to be an efficient way...which you guys showed.
 
tip: arrow-up = edit recent chat post ;)
6
 
Ahh right!! Thanks for the tip
 
1:31 AM
first time in The 2nd Monitor?
 
Facebook hangover maybe
 
@Mat'sMug sometime we should really consider pinning that...
 
Why discouraged? @SimonAndréForsberg
 
@Anirudh Because sometimes it feels like you code one thing and get two new ideas. IdeaOverflow
TimeUnderflow
 
But I think Facebook does allow editing of the comments later, which doesn't make sense to me....
 
1:33 AM
Can one of the moderators (@rolfl, @Jamal or @200_success) tell me which one of my comment-flags was declined in this question ? Unfortunately it doesn't show which comment flag was which...
 
remember that FB is BF backwards... it's dangerous :)
 
TTGTB for now
 
Oh yeah @SimonAndréForsberg sometime one may wish he simply had eternity to himself with those ideas flowing..

1:34 AM
@Mat'sMug and yet the concepts of the two aren't that distant from each other
oh, monkey here, then I can get an answer before sleeping
 
I believe this is Stack Overflow material: it's about the algorithm, not the coding per se. — TryPyPy Jan 21 '11 at 20:27
 
Ah, alright. I can understand why
 
I figured it was still relevant, especially given the subsequent comments
 
I'll try flagging another comment then :)
 
Well, if there is a meta post, then maybe not ;-)
 
1:36 AM
My helpful flag amount has increased tremendously recently thanks to me flagging obsolete comments.
 
SEDE for that, by the way ... ;-)
Jamal hated me for that
 
@rolfl He hated you for flagging obsolete comments? I hope he's not doing too many of mine then
 
/me goes to flag comments
 
Although...
2 days ago, by Simon André Forsberg
lol, you know which moderator handles your flags when you flag some comments as obsolete and then moments later the question is Jamalized
 
@SimonAndréForsberg Not really.... but it was a slog to get to 80.
 
1:38 AM
@rolfl Ah, that one I have seen before
@rolfl Well, prepare for a lot of more flags because I'm aiming at 500 ! I'm only at 177 right now :)
I think it has increased by about 30 in two days though :)
 
@SimonAndréForsberg If you get bored... you can always flag crap on SO. ;)
 
@hichris123 I'm not that bored
 
@Mat'sMug Lol..if you have a thread of comment and reply to comments going on it's just absurd to let the user change his/her stance after someone had actually replied
Don't know Facebook's Product team was thinking.
 
It is a secret concern of mine, that when we graduate, all these people are going to have high helpful-flag counts
 
@Mat'sMug Race you to Marshal badge ?
 
1:40 AM
Then for elections my numbers will not be great
 
@SimonAndréForsberg I have 128
you?
 
@rolfl I am on your side man.
 
@Mat'sMug 177
 
@rolfl Well yeah... but you've been a good mod, soooo
 
No, I have not been gaming things ;-)
 
1:42 AM
Don't you worry about that, @rolfl. Numbers usually don't say that much. I think that if you run for moderator in the elections, you will most likely get elected. I think you'd be my first choice. (As long as we stop disagreeing with each other...)
 
same here
 
I'll frame that one ;-)
that two ;-)
 
@rolfl s/two/too/
 
HaH^
 
1:43 AM
@SimonAndréForsberg - you know we can only disagree with each other safely because we agree on so much else?
 
Is it a problem... that I think more than 3 people would be great mods here? (not even including the current team, which I would vote for too)
 
how many mods would we get as a grad site?
 
@rolfl Probably yes, thanks to and . I don't think we agree on the tabs-vs-spaces issue though, that might cause a problem ;)
 
Not as many as would be good moderators.
 
1:44 AM
Maybe 4.
But no less than 3.
 
@rolfl Imagine if I would use and instead of .... brrr... scary thought.
 
I have been to other stackoverflow sites but I think this is a cool place to hangout sans some arrogant, haughty smugs whose sole purpose of being there is to over scrutanize
 
Anyways, throw new SleepUnderflowException("TTGTB");

We really need to graduate soon.

It is somewhat embarassing being a mod when so many people are capable, willing, and qualified.
 
@rolfl [status-DENIED]

A: What are the advantages of graduation?

Grace NoteGraduation does five things for you, mechanically speaking. Reputation privilege tables are changed. That answer really explains it so I don't need to go further. Given the rep distribution at current, this is actually somewhat negative since you have a pretty tiny fraction of 5% that surpasses...

 
@Anirudh Right now, Jamal, 200_success, and myself are appointed, not elected. From this side of things, it is one thing to be a mod, but another to be an elected mod. There's a difference.
 
what would that difference be?
 
well, @Jamal was sort-of elected ;)

Q: Code Review is in need of a new moderator

MalachiI know that we are a beta site, but from the looks of it, they only choose moderator pro-tems 2 weeks into a beta site. I think we need to follow the path set forth for nomination of a new moderator, if nothing else to show that we are a growing site and have enough active users to become a full...

 
1:59 AM
@rolfl I was just curious...as Mod needs to devote a lot of time reviewing things on the site and answering Meta questions maybe. How do you manage all this if you work besides it?
 
That's a good question. Right now I am with my wife, my parents, I am watching doc Martin. I work for IBM, and spend my days at work, and at night I am online with my team in China too.
I spend a lot of time doing other things, but I frequently 'flip over' to code review, and do things 5 minutes at a time.

yeah i know the design debate (D2) is kind of heating up these days, the question I'm referencing is not that bad a question per se because there's some well-thought out code and documentation in the library
it just so happens that the question itself alludes to the design
the really really grey area :)
i created the question too on Simon's comment as well
on an unrelated note, why are our rep higher here in chat
hahah
 
it's your cumulative on all SE sites :)
 
i sees
 
at the end, CR should see the glass half-full (aren't we a positive bunch?) and brighten the grey areas a bit. They do get answers still. The bad ones ought to be downvoted, but the answerable ones are in our collective hands to decide whether we want to answer or not - what's in-scope on this site, where we cast our close votes, is driven by us all. It doesn't make the black any whiter, it just makes more people enjoy their ride.
 
agreed.
my take on the question is that it should be allowed on the premise of its quality alone, but i'm not sure if i'm ready to conclude too that I'm just raising the bar very high for design questions
my personal stand on design questions in general is still OT in CR...
if i'm ready to conclude too*
that I'm just raising the bar*
silly me, just edited on my original comment haha

well the problem with design questions is that the code is inexistent. There is no implementation, just an idea. we shouldn't review ideas.

Ah I see
I'm a happy person now, and so is @SimonAndréForsberg soon
 
I've always found that the really interesting projects are in languages like C or C++, so I've never gotten involved.
 
@RubberDuck So I create my own interesting projects :)
 
I've always wanted to get into an open source project I could care about though.
That's a good point @skiwi.
 
I might contribute to Java directly one day
 
@RubberDuck What do you mean by really interesting?
 
10:51 AM
@RubberDuck Java also has some interesting projects!
 
Just anything that's ever caught my eye was in in C. That's all.
 
@skiwi You found a bug in JDK 8, you have done your part
 
I really don't like Java. I spent some time learning it once upon a time.
Maybe it's because I don't like building GUIs from code though.
 
@RubberDuck you don't have to do that
 
I couldn't ever quite figure out the builder in NetBeans.
 
10:54 AM
Use JavaFX... Swing sucks indeed
 
Me neither. I use Eclipse instead :)
Although JavaFX has the external Scene Builder
 
JavaFX 2.x sucks because of other reasons (Functional code without lambdas... is a pain)
 
... which I also haven't figured out and ask @skiwi every time about it...
 
I really do need to find a project to get behind though. It'll be good for my resume.
 
@RubberDuck In what languages?
 
11:05 AM
@Mat'sMug It does. I work in SQL Server 2005/2008 every day.
 
@skiwi - this suggestion just arrived in my inbox:
No idea if it is any good.
 
Are Java lambdas the same as C++ lambdas, which are basically Objective-C blocks and Swift closures?
 
@rolfl Thanks for the heads up, I don't know either

oneFrom = ^(float aFloat) {
    float result = aFloat - 1.0;
    return result;
};
oneForm is an Objective-C block. It takes a float as an argument, returns a float. And oneForm is a variable which can be passed to and fro.

seems pretty similar
DoubleUnaryOperator oneFrom = aFloat -> aFloat - 1f;
Is most concise you could get it in Java
but
DoubleUnaryOperator oneFrom = (double aFloat) -> {
    return aFloat - 1f;
}
Is also legal
 
That's probably pretty similar to Swift closures.
What's, DoubleUnaryOperator?
 
There's no FloatUnaryOperator to Java... so using a double there
an unary operator is an operator that operates on a single type, and is this case it's on the primitive double
 
So... how would you call that?
In Objective-C, or Swift, I'd call oneFrom as such:
float myFloat = oneFrom(10);
So it looks exactly like you're calling just a regular C-style function.
 
float myFloat = oneFrom.apply(10);
Difference is that in most languages lambdas are first-class functions
 
Why .apply? Are there other things you could do?
 
11:17 AM
While in Java they're still objects
DoubleUnaryOperator is a functional interface, that is an interface having exactly one non-default method
 
Ah.
 
Language-wise it's an object
but looking on the performance side of things, they're not as heavyweight as objects are
 
Hmm, I see.
 
So in specification similar, usage is a bit different
 
So you could define any one of these interfaces for whatever sort of lambda you wanted to create, right?
 
11:19 AM
Yes
 
An interface for a lambda that takes 3 ints and returns an object for example?
 
Correct, you'd need to create it yourself though
java.util.functions itself defines a whole load of functional interfaces already, to which everyone using Java 8+ has access
 
DoubleStream.of(1.5, 2.5, 3.5).map(oneFrom).sum()
 
One of the most common uses of blocks in Objective-C is to use one that takes a bool and returns void.
 
will give 10.5
That would commonly be written as:
DoubleStream.of(1.5, 2.5, 3.5).map(x -> x + 1.0).sum()

So, for example, when animating a UIView... the method takes a void -> void block (for the animations) and a BOOL -> void block, where the BOOL passed into the second block marks whether or not the first block completed successfully.
+ (void)animateWithDuration:(NSTimeInterval)duration animations:(void (^)(void))animations completion:(void (^)(BOOL finished))completion;
 
@Simon I guess I'm looking for a C# project. I'm still not the swiftest at it, but I feel like I'm learning enough to make simpler fixes.
 
@nhgrif That would be a BooleanConsumer, though I've never seen that in Java yet
 
Where (void (^)(void)) specificies the arguments for the block.
But you can also typedef the blocks so when you specify them they're not so ugly.
typedef void (^AnimationBlock)(void) <-- now animationBlock is a type that refers to a block that takes and returns void.
So now my method could be + (void)animateWithDuration:(NSTimeInterval)duration animations:(AnimationBlock)animations;
 
@sim because I felt dirty posting a will-be-hot question, linking in chat and on meta all at once. Undeleted now, if you want to answer it ;)
 
And then I can use it as such:
 
11:27 AM
@nhgrif wow I've been doing it wrong for a very, very long time </mega-facepalm>
 
Doing what wrong?
Group-By?
 
@rolfl Feels like you, me and @skiwi probably know that stuff already...
 
yeah
 
The only time you should ever convert a datetime to a varchar, that I can think of...
a) you really need to return it as a varchar because that's easier/better than convering the raw datetime in your application
 
@SimonAndréForsberg I have some of the theory, but I have not 'used' Java8 features properly
 
11:29 AM
b) potentially you need to sort by only a specific part of the datetime, like the day of the month?
 
@RubberDuck You can help me improve my Sudoku Solver :)
 
So, I have been getting some 'heat' on the random C# answer, because in many ways, my answer is similar to @ToppinFrassi :
@BrunoCosta - you seem to be under the impression that I am in some sort of competition with TompinFrassi, or Jeroen. Well, there is some truth to that. Jeroen and I had a lot of good-natured discussion about this problem yesterday in the 2nd Monitor (transctipt) and I invite you (or anyone else) to join us to discuss this morerolfl ♦ 35 mins ago
 
@Mat'sMug Honestly, I don't really think lolcode is CR stuff, but well... I can't really point at what's bad about it. And I recently posted Brainfuck so who am I to talk? But lolcode for me seems to just be C in disguise.
 
And how does that make LOLCODE different to ..... FIM++, or C++?
;-)
Time for me to put on that fire-proof suit, and grab some breakfast.
 
@rolfl In a way, exactly that. Lolcode and Fim++ is just C++ but with a completely wicked syntax
 
11:36 AM
@SimonAndréForsberg That could be interesting.
@rolfl At least LOLCODE reads like code. Fim++ reads like..... a letter.

Q: Is [lolcode] reviewable?

Mat's MugDown with FizzBuzz created a lolcode tag. Some (cough) brainfuck (cough) are even further down the esoteric alley. Given our current site rules, I'd tend to agree. I don't think allowing lolcode questions on CR will bring a massive amount of 'em. brainfuck has 13 questions since May 2011. ...

 
Does anyone know what synchronizing a pull request means on git/github?
 
well LOLCODE does have dynamic typing

@RubberDuck I have gotten a review on it, but don't think I have made all the changes suggested
 
11:55 AM
@SimonAndréForsberg I might be able to find some time to help with that.
 
@RubberDuck Feel free to fork it and improve it however you'd like github.com/Zomis/SudokuSharp
@RubberDuck yup, that's the one
 
That's cool. I starred it.
