Q: Could this solution be optimized? [DP problem]

possible answer invalidation by User1973 on question by User1973: codereview.stackexchange.com/posts/226786/revisions
 
@Peilonrayz your choice. It's rather very glib and blunt and some people don't like that. It wouldn't hurt your point to make it less blunt...
 
@Vogel612 How is it glib and blunt? The only parts that I can see being misconstrued as 'rude/blunt' are "ridiculous" and "get over yourself". If you take those out no one would bat an eye. I think it only comes down to me saying "get over yourself", that people are being snowflakes.
 
that's kind of exactly what glib and blunt mean, isn't it?
I'm honestly not entirely convinced that the question in it's current state is even on-topic ...
 
11:50 AM
I don't know what glib means and I can't find a single definition that fits this. So IDK, what do you mean by it?
 
I'm using it in the sense of something close to "tonedeaf".
though apparently that's not really what the word stands for ..
 
@Vogel612 I feel like we may start going in circles here, do you mean something along the line of "Unable to appreciate or understand the concerns or difficulties of others; out-of-touch."?
 
that is something I would use the word for, but not in this case.

blunt is for the nuanceless part.
not that the question actually needs any nuance...
 
12:00 PM
@Vogel612 Sorry, I really don't understand you. I've been told that when situations like this happen I'm 'being unreasonably difficult'. So I'd rather disengage and say my post is staying as it is, then continue an almost definitely unfruitful discussion.
 
oh, I'm not trying to convince you to change your post.
 
I guess that really shows how little I understand you, lol
 
just trying to help you appreciate the cultural differences in tone in the audience :)
like... as a continental European (especially as a German), the tone seems okay...
but I learned that being this kind of straightforward can be considered very rude in other cultures
 
JAD
It comes across as yelling at someone for a misunderstanding. OP didn't appear to realise that it's not worth worrying about the overhead of making a variable.
 
Am I correct in thinking that only the second half of the last sentence contains this problem? ("Get over yourself") If that were removed would the problem still exists?
 
12:35 PM
I would certainly remove the 'get over yourself': it doesn't add anything, and is a statement that reflects on the OP, not his code or query.

3:22 PM
@Mast Not taken personally.
 
This does work, but does not give a different result from just creating a new image. I do not maintain the code that the vendor distributes, but I maintain the tracking code that goes into the website, so I intend to throw things out that are not necessary. I am now not sure if that makes it on topic, but I did assume it would when I wrote the question. — Eike Pierstorff 1 hour ago
Looks like the guy maintains the code?
 
@Peilonrayz While I think that might qualify as maintainer of the code, I would argue the OP clearly does not know why the code is written the way it is since that seems to be the question they are asking.
Unrelated, is anyone going to take pity and cast the fifth reopen vote on this question (which, full disclosure, I already answered): codereview.stackexchange.com/questions/226586/… The question has been edited since closure to contain more background information on what the code is supposed to do.
