ZorbaTHut posted:You'd say "optimize it for 5 seconds!" and boy howdy it would optimize that sucker for exactly 5 realtime seconds. Regardless of how much CPU it was actually getting during that time. And to make things worse, it was buggy. So, depending on how much CPU it got . . . well, it might just spit out invalid assembly once in a while. Simulated annealing? By any chance did the assembler documentation mention a "temperature schedule"?

You just said "optimize for X seconds!" and sometimes it did. It would not entirely surprise me if, on the inside, it did exactly that.

I'm not going to post the code, but this description is painful enough: We have a SOAP service that accepts one argument... strXML. Whoever wrote this thing didn't really understand why you would want to use a webservice. Instead of just connecting via a client of my choice and calling the method remotely with a few arguments, I have to go look up API documentation to remember what methods are exposed by this service and then generate an XML document to pass as my argument... which in turn gets encapsulated in XML. Good job, developer.

Not so much code but the amount of people we see interviewing for our team who can't describe any sorting algorithms other than perhaps bubble sort and think that searching an ordered array takes O(sqrt(n)) time (or sometimes O(1/2 n) time) is pretty depressing It's also quite frightening when most of these people have decades of experience on their CV. Obviously a cursory examination of the internet suggests that these people are pretty much the bottom of the barrel, so why aren't we getting anything better than this? FWIW this is investment banking, so I assume the pay being offered is pretty competitive.

I'm working on a tile-based project with someone else, and they were doing the code for calculating the coordinates of the tile the mouse is over when you press the button. He had a huge series of if statements using the coordinates of the mouse to find the correct row and then column. I don't think he was happy when I replaced 500 lines of his code with 5 of mine.

Oh my god it's actually worse.  e: it just hit me that he's using a ton of if clauses and not if else. So every time this runs, everything has to be evaluated even if you already found your position. Also the variable i is freaking me out. And the fact that you have two variables called thiscol and thisrow. You have to post the whole thing.

Eh, if the guy isn't a hobbyist then it's a complete nightmare-level horror. I say cut the guy some slack. We all had to be that guy at some point in our learning of computer programming. What makes a coding horror to me is really based on how many years of school the person who wrote the code had, how many years of prior experience, and how much he got paid to write said code. If all of those are close to 1 or zero, then c'mon, how much can you really expect? There's also bonus points if the code is already used in production somewhere, and double bonus if it could kill people due to a bug. ErIog fucked around with this message at 23:33 on Nov 7, 2009 |

We all had to be that guy at some point in our learning of computer programming. Well blueberry did say that it's a tile-based project, so it's probably a hobby or possibly an assignment. But still, I'm a newbie, started programming from absolute zero about six months ago, have never written a line of C/C++ in my life and can still avoid writing that sort of code. I mean, if you see a ton of ifs like that and do not immediately think of a loop, then it's a logic problem, not a programming horror. I completely agree with your second statement though.

If you see a ton of if statements like that, and your first impulse is to replace them with a loop, then you're fixing the wrong problem. And you're probably just making things even less clear than they were before.
