when your co-worker instead of commenting a piece of old code wraps it in:

if (false) {
...
}

Took me 2 hours to figure out why my changes weren't working.

Copy paste from the internet, usually stack overflow without knowing what the fuck the lines do.
I saw this girl who was tasked with building a spring mvc application and she literally googled(yeah googled) "spring mvc web app" and copied from the first tutorial site and pasted it.
When errors showed up she copied everything from the second link and pasted it ... Wait for it... Without deleting the old copy but commenting it out so each file had 100 lines of code and 100 lines of comment

At my current project we use SVN, but today I noticed a colleague of mine uses another version of version control as well.

Example:
V1:
console.log('Hello, world!');

V2:
//console.log('Hello, world!');
document.write('Hello, World!');

V3:
//console.log('Hello, world!');
window.alert('Hello, world!');
//document.write('Hello, World!');

Every singletime Ive to remove 40 lines of comments before Im able to follow the code and refactor it.

Working for a company with solid procedures really makes me appreciate how important they are. Knowing someone will be scanning through my pull request made me *really think* about appropriate layout and commenting. Before I could submit any old code and the other programmer wouldn't give a monkeys.

I guess that's a poor reflection on my performance but, I'm working on it

<insert obligatory "long time lurker" statement here>

Started a role about 6 months ago. I'm the sole IT programmer. A bit of the mess I inherited...

- 100+ stand-alone applications/tools (luckily most of them aren't too big).
- No documentation.
- Some applications' only copy of the code exists in production.
- We only have production.
- A single file consisting of 30K+ lines of VB. Little to no comments. The one comment at the top says to keep old code by commenting it out and state what you changed.
- Previous devs didn't like foreign keys.
- No. Fucking. Version. Control. At. All.
- And so much more...

Luckily I was hired due to my experience so I could fix all these problems. Its actually a really great job.

I can't delete old useless code, I am afraid of deleting it and I always end up commenting it as if I am giving it a chance to prove itself. #rant
