proposal: x/debug/trace: add package for parsing execution traces · Issue #62627 · golang/go As part of #60773 (tracking issue #57175) I've been working on a new parser for the execution tracer, and to save work down the line I've also been trying to come up with a nice API that would work...

If you haven't been keeping up, Go 1.21 reduced overhead from ~10% to ~1%. 1.22 overhauled the format to improve reliability and add information. 1.25 has a built in trace flight recorder. And we have an active proposal (go.dev/issue/62627) for a trace parsing package to enable arbitrary tooling.

G2's are great. I carry a G2 0.38 with me at all times (when a fountain pen wont be practical). My everyday handwriting is tiny and requires a finer point. I was very unhappy with my Lamy 2000 until I sent it to a nibmeister who ground it down to a Japanese needlepoint. Now it's among my favorites.

Just adding my two cents here. I really enjoy Platinum carbon black and Sailor kiwaguro. Get some samples and see what works for you.

That makes sense. I've gotten into fountain pens lately (and increased my attention to mechanical pencils). Writing things down in general has been helping me declutter my mind and workspace.

Have you tried any fountain pens? Like a Lamy 2000?

Out of curiosity, what do you prefer to write with (pens, pencils, etc.)?

Gerrit Code Review

How often do people run into the SetFinalizer footguns in Go? (Accidental cycle, for example.)

Would a GODEBUG that does something slow but tells you when you've made a mistake be useful to you? (Maybe even just for tests, to prevent a regression?)

And ~24 hours later the raid 5 volume is rebuilt. I should really work on upgrading this thing while it's top of mind.

It might be time to replace my Synology DS415+. One of the drives is on it's way out and I'm not confident that it's going to recover if I replace it.
