@IsmaelMiguel first thing that I tried to do when I bought this computer was start up Hyper-V so I could try and run some virtual machines. and it crashed the computer, I did some extensive searching for several days, and found out that it just doesn't work with this computer set up..... I was so upset

200_success

Just pick the better or the worse version and make some remarks on it. What's the big deal?

Ismael Miguel

@Malachi I know I'm asking too much, but can you be much more specific with the model?

nhgrif

The big deal is that, best case scenario, doing that approach means that I'm not going to get my question marked as accepted, or I'll look obtuse because I spend time explaining something as if they don't know about it even though they used it in the alternative version.

Malachi

give me a second. I hate Windows 8 I should just go to 10

nhgrif

But ignoring the best case scenario, it frequently leads to bad questions, period.

And questions that are off-topic because it misleads people into thinking they can ask things they can't.

nhgrif

My answer wouldn't get accepted because I'm never comparing two pieces of code.

Every "comparative review" is a double review.

If the asker posted it as two questions, I post two answers and get double rep.

When he posts it as one, and we have a tag for this clown style of asking questions, I look like an idiot if I post two answers that independently review the code and make no comparisons.

Comparative review is arguably the worst idea this site has.

200_success

Suit yourself. You're welcome to choose which questions you want to answer or ignore. But don't abuse the closure mechanism to suit your tastes.

I'm not abusing the closure mechanism.

200_success

nhgrif

That's not an abuse.

I vote to close any "comparative review" which provides zero guide lines on how to determine which is supposed to be better or any justification as to why we need to review two pieces of code

Malachi

Why is that user undecided which of the two is better to the point that he must ask the question in this way? Without that critical piece of information, the question should be closed.

And my vote to close can never be an abuse of the system for as long as I think the question is off-topic.

I can be wrong, but being wrong and abusing are different.

@200_success You don't get it. I know I can comment on any aspect. I do that all the time. Why do I have to comment on two pieces of code instead of one?

Ismael Miguel

@Malachi That CPU doesn't support AMD-V. You can check on

(look for "AMD Virtualization")

nhgrif

The thing is... the users posting comparative review can't describe to us any criteria for better, and they can't explain why they feel the need to post two versions of the code, in most cases. And why? Because in most cases, they haven't even thought of it. They just post two versions of the code because we apparently allow that.

And we need to stop allowing it.

Q: The dwindling Fibonacci

I've recently taken a renewed interest in non-standard languages like Brainfuck and TIS-100.

@IsmaelMiguel Above should answer your question.

Ismael Miguel

Sadly, I don't do Python

nhgrif

If the user doesn't specify the criteria by which "better" should be decided (and the user almost never does, and that's the reason why I vote to close almost all comparative review questions), then how do I know what to recommend to the user, @200_success?

Mast

@IsmaelMiguel You don't need Python to be able to read it, it's very, very straight-forward.

nhgrif

00:49

Moreover, most of the criteria by which two pieces of code would be compared are objective and measurable criterion. In which case, the user isn't asking for a review. The user is asking the wrong question. The user should be on Stack Overflow to asking how to measure whatever metric they're trying to compare.

nhgrif

All that's really left, I think, is readability. But what's the value in comparing two pieces of code and saying which is more readable? Why don't the user just give the code that's performing how they want and ask us how to improve its readability?

Mast

On a totally not related note, I just hit Marshal at SO :-)

Ismael Miguel

@Mast Hard to understand what's going on when you don't know the language and the concept

200_success

@nhgrif Just use your own judgement. All questions are open-ended anyway.

nhgrif

00:51

You mean guess?

Guess at the context which the user hasn't provided.

200_success

If one is clearly better, state so. If it's a wash, state so.

Mast

@IsmaelMiguel Do you know fibonacci-sequence? The Nth value is the Nth-1 value + Nth-2 value. In this case, I shift them all to the beginning to save memory.

nhgrif

@200_success Define "better".

200_success

If they're both fine, state so. If they both suck, state so. It's all up to you.

Ismael Miguel

@Mast No, I really don't know

nhgrif

00:52

You're entirely missing the point.

What's better?

The user has put two side by side because they want to know which is better

the user almost never specifies by what criteria they define "better"

So it's just a double review.

200_success

The same criteria you use when writing or evaluating any piece of code.

nhgrif

You literally couldn't get this any less.

200_success

Suppose you gave the same task to two interview candidates.

nhgrif

When it's a single piece of code...

200_success

Would you prefer to hire one or the other based on the two different answers?

nhgrif

00:54

When it's a single piece of code, we can improve it's readability without sacrificing its performance. We can improve its speed without sacrificing memory usage or readability, etc.

We can make it better regardless of context or what the most important constraints are, even if we're optimizing something they consider insignificant.

200_success

So, you could write "A is more readable, but B is more efficient." That's a valid answer.

nhgrif

When a user gives us two pieces of code that do the same thing in different ways and ask us which is better without specifying any criteria to judge it on, then it is impossible to say.

@200_success It's a double review. It's too broad. It's two questions.

The user has to be expected to do more than just get away with posting two snippets.

If two snippets are okay, are ten?

How different do the snippets have to be?

Do I need to do anything besides say what the code does and post two snippets?

200_success

Ten is clearly ridiculous. Please be more serious.

Besides, would you really want to see ten similar questions? That's equally harmful to the site.

nhgrif

They are terrible questions and the only justification I've ever seen for them is that someone thought it was good for the site because people post them and so it's generating traffic...?

No. Ultimately, the point is that the user probably only actually needs one question.

But since we allow comparative review, user's are exploiting it to post questions without putting much effort into comparing the code themselves.

200_success

The author has a genuine desire to know which approach to use. Why is that not a valid question?

nhgrif

00:59

Why is psuedocode not allowed then?

Because that's what is being asked.

I'd much rather see a pseudocode question about best practices than these.

Because at least then, we have a much higher likelihood of the question actually being focused on what the user wants to ask.

But that's just not how Code Review works.

Which is fine.

strings ruby programming-challenge comparative-review

I consider that a good comparative review question.

nhgrif

It still doesn't define "better"

200_success

Splitting it into two would be worse. In my opinion, the regex is the way to go, and I wouldn't even bother considering the other approach.

tokland answered the other approach anyway, and got accepted.

Good for him, he got lucky.

That's OK.

nhgrif

So we're okay with a question that asks "Should I use regex or iteration in Ruby?"

That's what this is.

But nevermind this specific example.... because I'm not even here to argue that comparative review should be outright banned.

What I'm saying is that comparative review questions are on average of a drastically lower quality than questions that aren't comparative reivew.

And that I think comparative review questions should be held to a drastically higher standard.

200_success

But you voted to close what to me looks like a valid question. How is that consistent with not banning?

nhgrif

01:04

The question you linked, I can give it credit for this...

It at least expresses conflicting concerns about two pieces of code that do the same thing.

The user at least has some justification for why the code needs to be compared. What concerns are we addressing.

We're not really comparing the code, so much as comparing his concerns.

That's not most comparative review questions.

Most comparative review questions are "Here's two pieces of code that do X. Review them and tell me what is better."

That's just a double review.

And it's a bad question.

The user rarely elaborates on they're starting position of pros-vs-cons of the two code snippets. They don't give us any input on how they even got to the point of being stuck between two pieces of code.

200_success

It would have been kinder to at least leave a comment asking for clarification. It is a new user, after all.

nhgrif

Why? He doesn't even have negative score. We upvote too much.

If this had negative score, I'd bother with it

But since the community isn't going to close it, I'll use the one veto power I do have... and just not answer it. Sure, plenty of people can write answers to it... but not many know Swift hardly at all around here.

So there's that.

It's a bad question that the community is rewarding by leaving open and upvoting.

I appreciate your frustration in the code reviews of projects created in most of the off-shore companies, something like being deceived.

The size of the arrays is a compile-time constant and the distribution are types.

Ismael Miguel

Now I understood around 80%

Which is good, considering that I'm half-asleep

Morwenn

So the whole stuff was trying to figure out how to make a kind of double for loop for type and non-type template parameters at compile to cover every possible benchmark case.

Ismael Miguel

And it is working fine?

Morwenn

It is. It generated the results of the bencharks for the four sorting algorithms, for five kinds of distributions, for arrays of size 0 to 15.

Quill

@IsmaelMiguel No problem.

Which edit are you talking about, sorry?

Ismael Miguel

@Quill codereview.stackexchange.com/posts/100380/revisions

@Morwenn 0? How can you sort an array of size 0?

Morwenn

@IsmaelMiguel You do nothing.

Quill

lol

Ismael Miguel

11:35

Sounds reasonable

Quill

@IsmaelMiguel Yeah, no problem. Good answer btw

Morwenn

But I would have had to add yet another layer of tricks if I wanted to avoid the 0 case, so I considered supporting it because it costs nothing and avoids consistency problems.

Ismael Miguel

@Quill Thanks. Yours is a bit under-apreciated (ignore the spelling). You found a bug! That's more important than the style.

Quill

@IsmaelMiguel Ah, I found visually, but not physically. I found your answer much more rewarding for those looking to improve not only their current code, but the future code they'll write. And in size, too ;P

Ismael Miguel

@Morwenn Probably it must be as easy as if(count(array)<2){return;} (pseudocode)

Morwenn

11:38

@IsmaelMiguel It's trickier since the condition is a compile-time one.

Let's say that I have a sorter_n<int N> class template with a sorting method and I provided a specialization of sorter_n for N = 0.

Ismael Miguel

@Quill You fixed functionality.

@Morwenn How many lines of code is all that?

Quill

@IsmaelMiguel I actually made that point in a review today, with a superfluous length check mixed with a foreach

Ismael Miguel

Sorry the question, but what point exactly?

Morwenn

@IsmaelMiguel A full file of 36 lines. But it's mostly boilerplate. That's actually 8 lines because I have short lines to keep a consistent indentation.

Quill

@IsmaelMiguel Read the part about count($errors) > 1

Morwenn

11:41

template<>
struct sorter_n<0u>
{
    template<typename RandomAccessIterator, typename Compare>
    static auto do_it(RandomAccessIterator, Compare)
        -> void
    {}
};

Ismael Miguel

@Morwenn I though it would be huge!

Morwenn

@IsmaelMiguel That's only to handle the 0 case. That's already a big hammer to handle a small case.

Ismael Miguel

@Quill You forgot one thing

foreach($errors as $e) {
    echo $e . '<br>';
}

It should be $error, not $e

Also, you have mixed quotes

Quill

Did I?

Read the bottom

Ismael Miguel

I was talking about the tiny loop

But yeah, you still have mixed quotes

@Morwenn Was that pun intended?

Morwenn

11:46

@IsmaelMiguel Which pun? :o

Quill

@IsmaelMiguel I just literally snipped out OP's superfluous code, that much wasn't modified

Also, thanks for the heads-up about quotes

Ismael Miguel

@Morwenn I don't know if I can explain well, but 0 is a really small case

@Quill You're welcome. I don't know your preference, but I prefer to use single-quotes

Quill

@IsmaelMiguel I don't particularly care which, but, sticking to one and not changing style in between is important, do what you preach, or something, right?

Morwenn

@IsmaelMiguel Well, I can see what you mean.

Ismael Miguel

@Quill Exactly. I just prefer single quotes because of it's nearly-0 performance gain and because you can't screw up. If you accidentally leave a $ behind, inside a double-quotes string, you may be seeing weird stuff happening.

On a single-quoted string, you will see whatever you write

@Morwenn I see it wasn't intended. I don't know, but in my head it sounded funny

Duga

A: Repeatedly check URL for change on iOS

If you want a UUID, generate one. What you have isn't a UUID. It's just a string of random numbers. If you want to reuse a once-generated UUID multiple times, you can do that. static NSString * const uuid = [NSUUID UUID].UUIDString; If you're calling a variable URL, it should actually be ...

Good morning!

Greetings

Ethan Bierlein

What's the good word right now?

Lol, nothing, I take it

Ismael Miguel

? I don't get the question

Ethan Bierlein

oh, what's going on right now?

Ismael Miguel

As far as I know, nothing

I'm playing old versions of Minecraft, for nostalgia.

Ismael Miguel

Which versions?

Ethan Bierlein

Alpha v1.1.2_01

Ismael Miguel

Wow, that's ancient!

Ethan Bierlein

Back when the grass was bright green and the terrain generation hadn't been screwed over.

It's actually my favorite version.

Ismael Miguel

Why you say it was screwed over?

@EthanBierlein Excuse my stupidity but I don't get it :/

@IsmaelMiguel Which one don't you get?

@CaptainObvious I believe this is off-topic. "i copied this code somewhere from internet..."

@IsmaelMiguel Okay, I can find a link for fractal terrain, but I have to go in about two minutes, so I'll explain 3d density-based perlin noise later.

Fractal landscape

A fractal landscape is a surface generated using a stochastic algorithm designed to produce fractal behaviour that mimics the appearance of natural terrain. In other words, the result of the procedure is not a deterministic fractal surface, but rather a random surface that exhibits fractal behaviour. Many natural phenomena exhibit some form of statistical self-similarity that can be modeled by fractal surfaces. Moreover, variations in surface texture provide important visual cues to the orientation and slopes of surfaces, and the use of almost self-similar fractal patterns can help create natural...
