'night!
 
Debating if I should search for a good FF/Chromium bug to fix... or do a code review...
 
As far as CR is concerned, you should probably do a Code Review @hichris123 ;)
 
I need a good question to answer, first. ;)
 
12:36 AM
Yeah, the title matters, but I think it helped that it was
It's a meta-meme. The webz cant resist.
 
KTHXBAI
 
@RubberDuck I don't think one can tell what tags are involved just through the hot network questions list...
perhaps "LOL" sold it ;)

I'm right here, right?
@AlexisWilke Actually, even GCC isn't 100% C99 compliant; but you should develop C in concordance with the standards despite that. If a feature isn't supported, then a bug report should be filed. The the request isn't honored, then you should be using a different compiler with more apt developers. — syb0rg 38 secs ago
 
Is C99 dated at 1999? Just curious...
 
12:44 AM
If say so @syb0rg
 
@Phrancis Yes
C89 is 1989
Don't use C89
 
What's C for 2014?
 
The standard hasn't been updated since 2011 to my knowledge, so nothing?
 
-.-
 
I think there might be plans to update it...
 
12:46 AM
C11 then?
 
Yeah
 
Well, hell's gonna break lose in 2089...

Fair enough. I still see sometimes scripts that fail SQL 92...
 
Which reminds me of a bug I pointed out in someone's calendar code. It wouldn't show up until 2400 or something or something like that.
 
@RubberDuck sounds like somebody else's problem

hello
 
hey there
 
1:35 AM
My Java assignment asks for a menu, and I'm not sure if it should just be done in main(), or if it could be a class (the instructor recommends having multiple classes for good design).
 
We, we, we, is Friday, we is tomorrow is Saturday
 
@Jamal do you mean a GUI menu, or console-based?
 
1:50 AM
Console-based
 
even if it's for something small i'll extract it into a method so that readability in your main() method can be improved. :)
 
That could work. It seems odd to make it a class anyway.
 
I think so as well, that would be over-development
 
I guess the "use more classes" thing is more general, assuming that the main class doesn't count as one of them.
 
2:35 AM
For an ArrayList, how would I determine if an item exists based on a given field? In this case, I have to see if a Car exists based on the given license plate number.
 
could you use a HashMap?
otherwise, over-ride equals() to compare by the plate
there are pros and cons either way
 
I have to use ArrayList.
 
public Car {
argh
public Car {
nvm
public Car { public boolean equals(Object o) { return o != null && o instanceof Car && ((Car)o).plate.equals(this.plate); } }
something like that
and then you can call listOfCars.contains(car)
since that will compare by your Car.equals() method
the con is you have pretty much dictated what is the 'equivalence' for your Car class, instead of simple method to loop through your list to compare by an element's specific fields
 
public boolean search(String plateNum) {
        for (Car car : cars) {
            if (car.plateNum == plateNum)
                return true;
        }

        return false;
    }
 
car.plateNum.equals(plateNum)
 
2:44 AM
Ah, right
 
;)
 
Darn C++. :-P
 
yeah i know :D
no { } for your ifs too? Just curious
 
Oops. Yeah, there are supposed to be braces there.
 
and maybe just one more point on the method naming, consider containsPlateNumber as well?
search is quite generic-sounding
or hasPlateNumber

So, it looks like I cannot create instances of an inner class in main() (unless I make that class static, which I don't want). I was able to solve that by moving the inner class into a separate file, within the same package.

Q: To rename html files using C# for input to eBook creation software

GeorgeI have designed a tool that generates some html files and a css file in a directory , which then feed into a tool called Jutoh that uses these to make eBooks. However, my output files are of the form 1.htm , 2.htm and so on. Jutoh ranks 10.htm to preceed 2.htm and therefore, I wrote a method to ...

 
This works: CarDealershipRepo.Car car1 = repo.new Car("ABC", "Chevy", "Impala", 2014, 5000);
 
Don't overuse inner classes. My intuition says that Cardeserves to be a standalone class independent of CarDealershipRepo.
Use inner classes only when the inner class is highly dependent on the outer class.

hey @200_success - I wanted to point out that there's not much conversation on meta about reviewing these languages.

@Anirudh hi.
 
Hi @Yuushi
How are things?
 
not too bad thanks, yourself?
 
Little bugged.
 
5:19 AM
@Anirudh why's that?
 
Well it's about work actually.
My employer is literally forcing me to learn and work on python
while all this while I have worked on Java...
 
hrm, Python isn't so bad
 
Nope it isn't infact I like it's descriptive nature and fast paced coding
I deal for writing unit tests...
*Ideal
but the problem is I am neither a starter no an expert with Java....My plan was to master one language first then move to the other.
 
I think the experience with another language is a good thing, personally
 
yeah it does add to your skill set unless you don't end up with something like a 'Jack of all trades and master of none' ;)
 
5:24 AM
not only that, it also broadens your horizons
and in the working world, that can sometimes be how it is. Have to pick up whatever technology they decide they want to go with.
 
of course it makes you eligible for more opportunities in the industry
Which language do you work on Yuushi?
 
funnily enough, I'm using Python at the moment as well
 
I found my tutor.
Hah
Have you worked on Java before as well?
 
yeah, but not for quite a while
my Java is probably quite rusty
 
Humm that's what I fear.. _
 
5:29 AM
I don't think it's a big deal, if I really needed to work on it again, I'd pick it up again pretty fast
 
cool...good for you!
 
I think that's true of most programmers
if you've worked with it before, picking it up again isn't too bad
 
Can you suggest any good books to start with from the point of view of writing unit tests?
for python I mean
 
hrm, I don't really know of any books on it, but I'd just have a browse of the unittest documentation
(if you haven't already)
 
I see...I looked up the Nose framework..a bit kind of similar to junit

So, I'm not sure if there's a better way, but I'd say if it's working, that's a good sign. What I do want to comment on is your readability: constrai...

It's not that particularly hard to generate random numbers in order
 
within a limited range?
 
Depends. Is there a specified number of random numbers to generate?
 
it's variable
 
I mean, actually, no matter what it's not that complicated. There's a couple of different approaches.
If they want 10 random numbers from 1 to 10 generated in order without repeats...
Just return them all 10 numbers.
 
and then shuffle them like they're playing cards!
 
1:27 PM
Why do I have to generate the numbers in order? Don't I just have to return them to the caller in order?
 
that's an easy scenario
 
Why do we need them to start in order then shuffle them?
What do we need in the end? Ordered cards or shuffled cards?
There's no point in specifying they be generated in order if you want them shuffled in the end.
Right?
 
shuffled cards
 
Then why must they be generated in order?
You just need X random, unique numbers, right?
In a particular range.
 
yes that's the requirement, I was talking about generating numbers in order, because that's my approach to the solution
 
1:30 PM
I like @Jeoren's order by new guid answer.
 
while (someSetObject.count < specifiedCount) {
    // generate random number and add it to the set
}
 
that generates repetitions, and @rolfi already did that
 
someSetObject being a Set collection which won't add duplicates.
 
I am avoinding collisions
 
Like in Objective-C, NSMutableSet
It will only add the object if the object doesn't exist in the set.
I don't know what language you're using.
But surely there's a set collection that doesn't add duplicates to itself
 
1:31 PM
@nhgrif I'm trying to say that that implementation was already made by @rolfi
 
What's wrong with it then?
 
It creates collisions, I'm trying to avoid them
 
Define "collision"
 
if a random number is in the set you can not generate that rundom number again
random*
 
Clearly you don't understand how a set works, right?
Scroll to the addObject: method.
There are collections like this in most every language (Objective-C just happens to be the one I know best)
Adds a given object to the set, if it is not already a member.
 
1:34 PM
You don't add it to the set, but you still have generated it. If you're unlucky it could be a very long loop
 
<-- that. Thanks @Mat's
 
Then you optimize it.
 
Tha'ts what I'm trying to do
 
There's another approach
Create an array bools with one index per random number
 
that occupys to much memory I want to occupy O(requested numbers) memory
 
1:37 PM
Unless you can demonstrate to me that it definitely occupies too much memory (in a way that it is problematic for your application), then I'm not sure I want to continue helping.
A bool takes 1 byte.
An array of 1000 bools is 1000 bytes.
Even smart phones all have at least 1GB of RAM.
And I know there are other things going on besides just this random number generation...
 
@nhgrif I'm not the owner of this problem, and question. I'm just trying to provide a solution that follows this requirements that I'm stating.
 
I'd advise you take the same approach then.
Premature optimization is the root of ALL evil.
 
@nhgrif I don't even know if that's possible yet but let me try and i'll let you see if I get here.
 
In fact, in my experience, I've seen programmers attempts to optimize things end up resulting in a worse end product.
Lately at work I've been working on an app to talk to assembly line machines. They store information in various registers.
The protocol they use to communicate to the network allows them to transfer 125 registers at a time. The actual registers they use though (in this particular case) are no where near that many.
The C++ programmers who write the code for the machines suggested that I should only grab the registers that actually have data. That's fine...
I'm not "wasting" execution time parsing registers that will always have all 0s.
But the machines also have a polling frequency limit.
And the time it takes to parse all 125 registers is FAR less than the time I have to wait between polling opportunities.
Just grabbing the useful registers uses less processing power and less memory... but it's slower.
Because even with an old iPad set up polling 5 different machines on 5 different threads, plus a main thread updating the UI, even when I'm polling all 125 registers, I'm still seeing less than 20% CPU usage.
 
@nhgrif I'm laughing at this moment, I'm sorry. I don't know how a talk about random numbers ended up in network protocol problem...
 
1:44 PM
Don't waste time optimizing what isn't a problem.
That's the point.
Don't waste your efforts optimizing something that's not a problem.
 
@nhgrif I'm well ware of that, just let me try ;)
@nhgrif THERE IS A PROBLEM. That is the point!
 
What is the problem?
Is this problem posted to CR or SO somewhere?
 
see @rolfl implementation and see what the problem is if you need 1.000.000 random numbers from a 0 to 1.000.000 range
 
Then you just return an array with all those numbers in it.
If the number of randoms needed is greater than half of the range, then you start with a full array and remove random objects until you have the right count.
 
gotcha but I will still try to do that in other way. May I?
 
1:49 PM
You're welcome to, certainly.
 
@nhgrif @rolfi is well ware of that problem. and he suggested that discussion should continue here.
 
I know. I at-ed him to see if he were around.
The last character in his name is a lowercase L by the way, not an I
