Q: My program generates a yearly workout program in the variation of 5/3/1

BrandonI've been building this program for around a week or two on my spare time because I'm slowly starting to figure out how to code better. This program generates a yearly 5/3/1 cycle that is exported to a CSV file so you can easily print it off if you want. Below is my code: /** * */ package ...

@Duga Fine, fixing the ``` bug.
 
Huh, what's going on here with the bots? What purpose?
 
I don't understand you. Are you asking what the purpose of Duga is?
 
Oh, found the meta question about this chat room :)

A: Welcome to The 2nd Monitor!

QuillAlthough it may seem daunting to start talking in an unfamiliar room or site, The 2nd Monitor is a great room, and the friendly regulars will help you to feel right at home. Some questions you may have: How do I ask questions or get help with a post on the site using chat? What topics are ...

Interesting. So the Captain is just indicating new questions and the Duga is for some stats and whatnot. Makes me think if Crypto needs something like that as well.
 
Yeah pretty much
 
Oh, "possible answer invalidation" happens if the question is changed significantly?
I was wondering, I just answered that last one...
 
2:32 AM
Kinda, it's if any codeblocks change. Since that's likely to make the Q&A's not make much sense - like updating the question with feedback
 
Ah, but it is not smart enough to detect the removal of ``` :) That makes sense I suppose.
(from a programmers perspective anywho)
@Peilonrayz I voted down one question which was just a single code block of a few 100 lines. Is that acceptable here? Tried to look on meta when code is just not taking any programming practices in account, but yeah.
Hey, those posts of today / yesterday took me over 1000 rep :) My rep line looks like a staircase to heaven. Should visit more often.
 
@MaartenBodewes TBH I'm not sure why Duga catches that. Because technically it's not a removal, it's adding a \n after it...
 
@Peilonrayz I think there is a bug where ``` is considered part of the code if it doesn't end with a newline.
Of course, it is not part of the code anymore after the \n is added :P
 
@MaartenBodewes You're allowed to vote however you wish. Since I can't see the question I can't really give an opinion, as it doesn't make to much sense to me at the moment
 
It's this - uh - blob of code:

I'll remove my comment anyway.
 
2:39 AM
@MaartenBodewes Exactly
 
I would not even know how to start picking that together.
We at crypto have the same bug, of course. MathJax enabled and code blocks...
 
As for the question, the description is lacking. So I can understand a DV for that. But I don't really see a reason to downvote for the code - albeit I don't know Java.
Wow. I'm surprised they don't just append a newline to the end of posts automatically like most editors do now-a-days.
 
Maybe they simply didn't think about that yet. It seems a perfect solution to me, really. If not end with newline, add newline, done...
(and do that test twice, once in JS and once at the server, so the posts will always get that newline but the server doesn't have to do much most of the time)

It would be more appropriate for Code Review, I think, but since your pivot is the first element, less will be empty and more will be full, so the performance will be O(N^2) or so. (I did actually encounter this case in my current project!) Next, there is a lot of list creation and deletion; I count 5 new lists each time round, which will be slow and may cause stack overflow issues. If you wish to continue reviewing, please post to Code Review, thanks. — Ken Y-N 22 secs ago

@MaartenBodewes Captain is a feed in disguise, so setting that up for Crypto won't be particularly hard. If you want a Duga, ask @SimonForsberg and/or start here. Welcome to The 2nd :-)
@MaartenBodewes It's a poor question, so don't worry about people disagreeing with a downvote. But poor code doesn't necessarily make a poor question, so try to keep the difference between those in mind. After all, we all started somewhere. May need a tag (one of the few allowed meta-tags) if it's that obvious though.

Its doing analyzing images about a colored mark, doing ocr and storing as pdf and tiff. Its doing this for around 120 pdfs containing 3 pages each.
 
oh wow that's a lot of work
 
Ah, ja, that will take a while.

Usually this would be finished without ocr on a decent pc in about 3 minutes ;-)

Has 2 close votes... for a getName method... Overkill IMO.
 
@SimonForsberg Perhaps. It does show the author didn't bother to test it though, since it would be immediately visible.
For someone claiming to want to get more serious...
Went HNQ by the way.
@Heslacher So, the documents are first marked and the software will only OCR the marked pieces? Or OCR the entire page and use the marked parts for archiving purposes?
Categorize documents based on colour while OCR'ing them all?
 
12:29 PM
Nowadys the mosted used solution to separate a stack of pages into documents would be to stick a barcode onto the first page of a document. Instead of doing this with our app you would use a highlighter to place a mark on the "non printable" area of the first page. You can mark one "line" inside the first page of the document as well which will be ocred as well.
That could be an invoice-number or whatever. Based on the position of the border-mark you can assign one or more filings to that document where it will be stored. Based on the settings of these filings the app will do ocr, sign the documment change from color to grey or black and white and reduces the dpi of the resulted document. The currently integrated filings are store in a folder, send per mail, store in ELO (dms-system) or in PRO-FILE (dms).
I am in the progress to turn this app into a service for a customer. We have an api for recognition of the colored markings as well.
Well, it seems there is another memory-leak taking 1.8GB, will need to find it now.
 
Ah, like that.
