Q: Heap-allocated fixed size array with memory-reusing type tranformation function

ktbI would like to use a std::array, but am operating on sufficiently large arrays that stack allocation is not reasonable (and fails using default stack size). I also needed a function that operated much like std::transform, but always in-place. The issue being that many of these transformations ch...

Q: First post: understanding RSA key generation and implementation in Java

JonathanThis is an attempt to leverage Java's BigInteger class to implement the RSA algorithm, as well as md5 and sha512 hashing functions to generate keys for what I hope to be strong cryptography. My prayer is that some of my ideas are novel and not just bad. This is a test, this is only a test. 'Key...

@rolfl What is your opinion on edits like this, where among other things the capitalisation of imports is changed?
 
@AbeA. As long as you call the log method once, your code will fall in a pattern precode-log-postcode. This could be made more generic through delegates, conditions or just overriding methods. But to suggest a better optimization, we'd need to see more code. Consider posting the code at codereview.stackexchange.com for a review. — Wim ten Brink 49 secs ago

@rolfl I've been looking at really old C and C++ questions and answering those I think are worthy, and VTC for the ones that should have been closed. If you can take a pass through the close vote queue I'd appreciate it.
 
@rolfl Some of them, yes. Others, too much as well.
He means well.
 
@Mast I've rejected 2 or 3 and approved the others.
Generally I don't like it when he modifies code.
 
Me neither.
 
@pacmaninbw Hmmm , I hate the concrete-context close votes, is this an example of the question you thing should be closed? codereview.stackexchange.com/questions/232150/…

5:35 PM
Yes, I was looking for a real example of how to use the code, but that is a much more recent question than the others, it was asked in the last few days.

Yeah, that has plenty of context. Why does it need to have an actual use case presented? Vote-to-leave-open

There are plenty of zombies out there that I don't like. Doesn't mean they should be closed.
 
OK, my bad.
 
5:52 PM
@pacmaninbw - I went through the queue. In almost every case where you commented asking for a working example usage, a test case, or similar, I voted to leave open. Code Review does not need a complete program to be considered on-topic... but, what is posted, has to come from within a working program - the difference is subtle.
There were some cases where I thought that the question was possibly off-topic for other reasons, but my language-specific knowledge was not good enough to ascertain for sure, so I skipped those.
 
@rolfl Thank you for your time, I'll think about my definition of LCC.

If it were someone else, @pacmaninbw - I would typically say something like: Just because the context given in a question is not sufficient for *you* to make the post reviewable, does not mean that a person with the right background/skills won't find it reasonable.

Q: A prime numbers enumeration optimized for speed

Wim ten BrinkI know there is this thing called "Eratosthenes" but that requires the allocation of a large array while I want to find (small) prime numbers fast, yet without needing too much memory.

@Mast Yes, better clean-up than I have done.
There have been years when I haven't earned any rep, because I was busy working.
This is my best year.
 
I think I'm at 1k a year for the past 2 years. So with this speed, I'm going to need about 12 years to reach 20k.

Q: Is there any way to make this code perform faster (deep learning)?

@benjaminaaron_m - while @410_Gone is correct, there is often a lot to be learned even with impacts from other programs.
Also, you will never get a 100% clean profile.
It's important to always take a statistically significant sample of results before drawing conclusions, whether that is running the program multiple times, or some other mechanism for doing the code-under-test in a way that mitigates any external factors.
 
@ar2015: Read Checking if a number is prime in NASM Win64 Assembly which I linked earlier. You can use div r13d to do division with 32-bit operand-size, which is about 2.5 faster on Skylake CPUs for the same small-number inputs. — Peter Cordes 59 secs ago

Q: Solving Subset-Product in Python

The purpose of the script is for my empirical observations of the similarities between factorization and the NP-complete problem. The code compares two sets (or lists) from the origina...

 
Generally, in my experience, if you're profiling (not comparing) then other programs don't typically matter. But, they technically do.
If 70% of your time is spent in one method, chances are cleanliness of the test didn't really affect it that much, and that one method is definitely the bulk of your work.
 
That: ^^^ But I fear that the OP took your response as an absolute, and now he's doing youtube and e-mail instead of profiling ;-)
 
Hahaha possibly...I should have clarified more.
I do a lot of A/B benchmarks, so for me cleanliness is important because I need the comparisons to be as exact as possible.
Generally, I'm looking for A > B or B > A, so they should have the same relative interference.
That is, if I was watching YouTube during A, I either need to rerun A or do the same for B.
Though, I have a dedicated (minimal) machine for those benchmarks, so it's less an issue for me.
