Perl 10.1.0 doesn't build on Cygwin

Stack Overflow career spam

I got a fairly innocuous spam from Stack Overflow advertising their new job hunting site, where they would like me to upload my resume.

Sorry, Stack Overflow; I'm smart for that (thanks to Andy Lester). I also don't particularly appreciate the spam, although it's the first I've ever gotten and wasn't too obtrusive.

SVK retired

I didn't notice, but SVK retired in May. Thanks to its authors and Best Practical for providing it. I agree with the sentiment that people moved on from Subversion quicker than expected; I am glad that I went on to git instead of spending too much time with SVK, although I would've liked to have learned it earlier and gotten to know it better.

Instructions: in the middle of a git rebase conflict

So you've done a git rebase, and a conflict was reported.

The instructions you originally received (which have long since scrolled off your screen), were:

Failed to merge in the changes.
Patch failed at 0051.

When you have resolved this problem run "git rebase --continue".
If you would prefer to skip this patch, instead run "git rebase --skip".
To restore the original branch and stop rebasing run "git rebase --abort".

Thankfully, I can usually remember the --abort switch.

What you haven't been told is:

To get a list of files with conflicts from git, instead of trying to use ack and stuff and picking up false positives:

git status 2>&1 | grep 'needs merge'

After correcting a file with a conflict:

git add FILE

After all the files are added, run a git --rebase continue, without doing a git commit (just in case there was any confusion, and there usually is, for me).

There are a number of other "in the middle of a git conflict" situations that I encounter, none of which are handled the same way, and I hope in time to produce a complete series of instruction cheat sheets for them.

Somebody give me some tips on how to reword this to make it a "real question."

regex spelling

People who think regex should be spelled regexp should be dragged out into the middle of the street and shot.

I guess I have to do this again. It's tradition.

Eventually, we are going to run out of these.

Have a special day, everybody.

What's the deal with relative times?

It seems to be all the rage today for sites to give timestamps only in an approximate, relative fashion: one hour ago, two days ago, etc. Among other sites, I see both Twitter and StackOverflow doing this, so apparently it's popular for both the technical and the general communities.

I can't figure out why. It's annoying to see two posts marked "one hour ago" and wonder which one was posted first. It's particularly annoying to see two posts marked "one hour ago," then check back and see that suddenly they are an hour apart, because one of them was "two hours ago" and the other is still "one hour ago," then to see them both finally mysteriously become "two hours ago."

Are real timestamps actually that hard for normal people to understand? Am I the only one in the world who ever wants to know if two posts are a five minutes or fifty-five minutes apart?

My favorite message board is hosted on UBB.threads (not my favorite software, but the community is good), which I think gives the user a profile option to disable this inanity. I can't find that on Twitter, and I'm about to check Stack Overflow, where I bet I won't find it, either.

Who thought this was a good idea? Who decided it shouldn't be a per-user option? And why in the world is everyone copying it?

Environment variables are not programming-related

It must be true. Stack Overflow says so.
