I cannot seem to get through to my team that commented out code is annoying

I think I'm just going to write it down each retrospective as something that is bad practice, let them disagree, and then write it again the next time

Anonymous

@Rainbolt Comment them out. Any time they start saying/doing something stupid, draw // in the air with your finger

@Rainbolt I just make a separate file.

The latest commenting shenanigan actually killed the build. There are now twelve files checked in with /* and no closing */

To make things even worse, there are if blocks commented out except that the inside of the if is not commented

If you have especially important commented out code, make it stand out by using #if 0 ... #endif rather than a comment. (Works for C/++)

They should prepend their comments with "commented out, just in case we want to quickly reintroduce bug #12345"

Anonymous

Really though there's 0 reason to comment out code if you're using version control

Anonymous

Doing a diff on the two versions will tell you the exact same thing, and your code stays neater

It is because of version control that I can see who made the change and when, and compare it to the previous version.

Wow. They commented out this chunk of code, then they copied and pasted the entire procedure into another procedure including the commented out chunk

Greetings, coworker of Dr. Rainbolt.

4:00 PM

I just got another code review, and all of the commented code is uncommented

Not removed... uncommented

@Mego it's moneyscript

He resolved the bug by commenting some code. The bug was reactivated, and he resolved it a second time by uncommenting the code. I am so confused.

Perhaps he is testing the consistency of our testers?

This guy knows a lot about Bridge...

Has anyone here considered if it was possible to have a language fully consisting of one char? (Like: $,%,#,O,1,~, etc)

(Combined with spacing/indenting (Like python)

4:10 PM

But you can save so much server space by properly golfing your code!

"Our entire codebase is entirely unreadable and unmaintainable. But on the bright side, it's now under 10 bytes!"

Anonymous

4:24 PM

It's quite simple really

Anonymous

You take your current codebase, golf it, and compress it.

Anonymous

Then you write a CJam program to output the compressed version

@Mego You can also save server space by only saving your code to your local machine and passing it back and forth in emails. That doesn't mean it's a good idea.

@Mego In code golf, you don't care if somebody pipes os.system("rm -rf /") to your code. In real life, you do.

Anonymous

And then you write a CJam program to output that CJam program, and so on, until it stops getting shorter

@AlexA. PanicSort you say?

I'm fairly certain I didn't say PanicSort.

On a related note, a former boss of mine once told me that she didn't know what the -fr meant in rm. She said, "I think it means 'from repository.'"

100% good code I promise

@AlexA. You're missing the point. If the code contains input(), which automatically evaluates the user input, and the program reads os.system("rm -rf /") from STDIN, it will wipe the hard drive.

Even better

(Well, not really, since no root privileges and rm refuses to operarate on / without additional switches.)

The fact of the matter is, it does not meet our standards, and so shouldn't count
