Q: Using author comments in posts

Getting the gears from an SO roller.... If I can convince him, politely, why it's off topic, that would be good....:
@rolfl: Can you please explain how this question's code is not in keeping with your own advice to post code that is "neat, focused, and mostly issue-free"? The code in this question contains everything that is needed and nothing that is not. — Greg Hewgill 4 mins ago
 
@EthanBierlein So you know, you do have blockquotes, and they can go into lists.
 
12:05 AM
Yes, I know what blockquotes are.
If I need some, you can edit them in.
 
This is not Stack Overflow, where they want an MCVE/SSCCE to make the problem as general as possible. This is Code Review, where we want your code, so we can review it. Hypothetical code is very difficult to review because it's entirely cut off from context. — QPaysTaxes 13 secs ago
@EthanBierlein That's what I'm doing, yes. In addition to other touch-ups
 
@QPaysTaxes - tread carefully please....
 
@QPaysTaxes Slight suggestion: When another user has already commented, with something very similar to what you want to comment, you sometimes don't need to add another comment at all.

@rolfl You might want to post a comment on that question that they should take it to meta.
 
@SimonAndréForsberg Didn't see Rolfl's comment, actually
 
@QPaysTaxes I don't think this comment is helping at all:
@Daniel The problem is that, on Code Review, hypothetical code is off-topic. Whether or not 'everything needed' is contained, there's a reason it's closed as off-topic: It's off-topic — QPaysTaxes 1 min ago

12:12 AM
@QPaysTaxes - when I ask you to tread carefully, please respect that.
 
The monkey has much wisdom :)
 
Hey Greg.
 
heh, I'm a "roller" huh? :)
 
Yup ... at 400+K you deserve at least that ;-)
 
I prefer to think of it as "experience points" instead of "reputation"
 
12:16 AM
Nahhh... that's why I am 42 ... that's experience points
 
@GregHewgill That's very well stated!
 
The issue with that question is that reviewers have to guess and infer too much when doing a review.
I can look at it an point out 10 or so things that make no sense.
 
anyway, I was working on an answer to that scala question when it got closed behind me, so I couldn't answer it. (I don't really know scala, but I was taking the opportunity to learn something.) It seemed to me to be a very focused bit of code that could indeed be reviewed.
 
There's a lot to say about it, but it is all fuzzy and ugly, and open to interpretation.
 
I'm trying to branch out a bit from just being a "roller" on SO, so I'm trying to get a feel for what's on topic on CR.
 
12:18 AM
as an example, why declare the val as 10, and then subtract 1 in the range?
just declare it as 9.
but then why have 9?
why not 0?
in which case, why have the loop?
just comment out the code and be done.
 
@GregHewgill We do appreciate SO users coming over and learning about what's on-topic here. Very welcome.
 
every reviewer can take a different spin on the problem, and interpret the code a different way, and all of them will be wrong.
 
that ^^
We have had way too many "But that's not what I meant" comments posted by OPs after an answer was given.
 
@rolfl But how is that any different from most "real" code out there?
 
Also, if someFunction is a mutator method with side-effects, it makes a big difference.
if the method was called "updateDatabase" would it be different?
or even "println(....)" instead of "sqrt(...)"
 
12:22 AM
yeah, there are details like "does the order of calling someFunction and anotherFunction matter?" but I'm not sure that would necessarily be clear even if the OP had posted that snippet from "real" code.
 
@GregHewgill Real code leaves much less room for interpretation. Real code leaves the what very clear, it is just up to you to guess why (unless it has been explained).
 
We have found, in the past, what we call chamaeleon questions.... and they are a real problem.
 
yeah, I can certainly see that. SO gets those all the time.
(usually known as X-Y problems)
 
chamaeleon questions change as the asker revises them, and someone puts a lot of effort in to an answer, and suddenly it is thrown out because the question asker changed a method, or assumption.
we are strict about that on Code Review, but then very relaxed on duplicates.
you can't change the code after a question is answered, but you can re-ask it with revised code.
 
@GregHewgill Exactly. On Code Review, answers often question design choices that has been made. If we see the real code, we might suggest an entirely different approach to the real problem.
 
12:26 AM
Seems like it's a challenge for an asker to decide what is the correct balance between including too little (and being accused of posting sample code), and including too much (providing an attack surface that's too large)
 
I agree. it is an identified problem.

Q: How to get the best value out of Code Review - Asking Questions

rolfl I have a project I am working on, and I would like some, or all of it reviewed, how can I ask for this review on Code Review in a way that produces the best possible value? This is not about a question being on-topic, or off topic. Rather, this is about making on-topic questions great qu...

 
A thing that commonly happens on the "How can I do this better?" questions on SO (that does not contain real code) is that people are trying to be 'clever' or funny in one way or another, by focusing too much on the example code that the OP posted, posting suggestions that would not work for the real code. We try to avoid that here.
 
We do have a range of "span" for questions... and recommend people post smaller sections of code for more detailed reviews, and larger swathes for big-picture reviews.
 
@GregHewgill "attack surface"? Is that really what you would call it? How about "rooms for improvement?"
 
But, the code aalways has to be "real".
It does not need to be "complete".
or even compile (if it is a subsection of code), but what's missing should be blatantly obvious.
 
12:29 AM
well, I'm being slightly deliberately provocative by saying "attack surface". By including a lot of code and context, the asker opens up a lot more room for "suggestions" that might be low-hanging fruit and not really what is needed.
and now I can't immediately find rolfl's answer on that topic because I closed that tab and the question in question is now gone.
 
I tru to recommend people put as much code in as they can expect to be reviewed in about 15 minutes.... or, alternatively, expect a review that takes 15 minutes to complete.

A: Asking questions - including full code

rolflI have my 'pet theory' about Code Review. This is my personal theory, and it is about human psychology, so you will have to take it with some salt..... It goes like this: You post code for review, and... noone knows how good you are as a programmer they do one of two things: find the most glar...

???
 
15 minutes? Okay, then many of my questions are out ;-)
 
that one, merci :)
 
@SimonAndréForsberg I know I often spend more than 15 minutes, but 15 minutes is the tipping point.
My dinner is served ... I apologize ;-) Must get it while it is hot.
 
@GregHewgill Who decides 'what is needed'? By posting more real code sure you are opening up to more answers, some might not be what you are looking for of course (suggestions to rename something from an already quite good name for example), but I believe that reviewers tend to capture 'what is needed' quite well.
 
12:35 AM
Well, for example, with this question we're talking about how to write something in a functional style in Scala. Sure, the OP could have included more of the original Java code, but what benefit would that be? The OP is asking about the functional style aspects of one loop.
Perhaps the problem is that question would have been better suited on SO in the first place.
 
@SimonAndréForsberg mind if i chime in on this?
 
@mjolka You're always free to chime in
 
so here's the scala code
val nvars: Int = 10
val vars: Array[Long] = new Array[Long](nvars)

for ( i <- 0 to nvars-1 )
    vars(i) = someFunction(i)
    anotherFunction(vars(i))
}
say i answer, "You can write it like this: (0 to nvars - 1).map(someFunction).foreach(anotherFunction)"
OP replies, "That won't work, I need the results of someFunction later in the program."
or "That won't work, someFunction and anotherFunction mutate some global state, so they must be called in turn."
 
yup, both good points
 
@GregHewgill It's the someFunction and anotherFunction identifiers we're primarily concerned about, and as it is a Scala question, we're more concerned with the Scala code than the original Java.
We do have an 'on-topic magic question' that asks: 'Do I want feedback about any aspects of the code?', which is often implied when posting on CR. Code without context make that hard to give... So while the question is asking about one thing, generally answers may cover more than what the question is asking about.
> Is code included directly in my question? (See Make sure you include your code in your question below.)
Am I an owner or maintainer of the code?
Is it actual code from a project rather than pseudo-code or example code?
Do I want the code to be good code? (i.e. not code-golfing, obfuscation, or similar)
To the best of my knowledge, does the code work as intended?
Do I want feedback about any or all facets of the code?

@AlexL You may discuss this question here.
 
@GregHewgill Good Code Review questions explain well what the code is supposed to do, when example code is posted, the code essentially does nothing. You might say that it 'loops' or that it is using recursion or whatever, but that itself is not doing anything useful. Why does it loop? What does it do in each loop? etc... those are the important questions.
And now it's time for me to go to sleep.
 
@SimonAndréForsberg Thanks, I now have a better idea why that scala question was originally closed as off topic. Still learning how to identify on/off topic myself for CR.
 
@GregHewgill We do have this MSO question that we've shoved up the face in SO users been referring too when we notice bad recommendations to post on CR:

Q: Be careful when recommending Code Review to askers

The only problem is that there are a lot of questions redirected to CR which don't belong there. So I want to ask that the users who direct askers to CR (or request migration of questions...

Generally, these six 'magic questions' are a good way to check if it is on-topic for CR:

'working, real code' is the parts were most questions get closed as off-topic. If you have working, real code, then it can likely become a CR question.
working = working as intended of course. Some people have a hard time grasping that.

A: PHP Base64 ByteArray Decoder

QuillYour code is generally clean, you have accurate comments & variable naming is mostly consistent. $raw_bytes and $byteArray use two different types of naming. It's best if you choose one style, and stick with it. With return ($encoded == "AQ==") and return $byteArray[0] == "00000001", you don't ...

 
@Quill Nice one.
 
@Mast Thanks. :-)
 
FYI, I have been in contact by phone with a mongodb representative. She asked me to post this question in the Mongodb google group (groups.google.com/forum/#!searchin/mongodb-user/…) and an answer has been posted yesterday mentioning that : "Thanks for reporting this. I've opened a ticket in the ruby driver JIRA project if you'd like to track it: jira.mongodb.org/browse/RUBY-946 A fix is in code review and will be released with 2.0.5 soon" — Thierry 46 secs ago

@CaptainObvious Gotta love the auto-commenter ;-)
 
@CaptainObvious This makes me wish we could still review broken code
There is so much that can be improved in this code and doing so might show the OP the path to the error

@Morwenn: By pass-by-value idiom do you mean Sean Parent's idea of taking sink arguments by value and moving them into the called object?
 
@mjolka that sounds like an awesome project
However.
I have exams until June 15th.
I have to host a guest between June June 20-25.
I leave for Argentina June 27th until August 3rd.
I have exams August 20th-September 3rd.
I leave for Boston September 18th-25th.
I have a 3 month internship starting at the start of October.
So you can see how it will be hard squeezing stuff in there
