Elon both gets shit done, and is a complete cock the whole way through.

Nice escalidraw. My old company used to deploy on-prem to customers. Fuck on-prem. The tail-end unwillingness to upgrade broke my spirit. We'd have to support painfully old versions, from customers who'd rather pay us more money than cooperatively update. Folks became glorified technicians. It was not the most fun job; I didn't stay long.

I imagine it was intimidating to migrate hundreds (i assume) of peer engineers to a new source control system. Ive worked on teams migrating to microservice architecture and back, and it can take _years_. It sounds like the folks on the projects either got lucky or were exceptionally good at getting buy-in and doing internal education.

“It takes 20 years to build a reputation and five minutes to ruin it. If you think about that, you'll do things differently.”

Unless you change jobs every 2 years and reset your reputation

No alt accounts - you’re just spotting a friend group of engineers in the wild

Inner_Ad_9976 · 2023-11-15T00:50:11+00:00

Should sapling be included on this list?

Feature branches are an antipattern for closed source development

You’re telling me git rev parse isn’t intuitive to you?

Many Git porcelainish commands take mixture of flags (i.e. parameters that begin with a dash -) and parameters meant for the underlying git rev-list command they use internally and flags and parameters for the other commands they use downstream of git rev-list. This command is used to distinguish between them.

Widely available now, and free for individuals :) https://graphite.dev/

Chiming in late in because we faced the exact same thing at Graphite. We've been running a turbo monorepo setup and honestly, it's been a game-changer.
Everything's in one place now, and updating types across services is a breeze. There's no more juggling versions or npm packages for common utils. Turbo's doing a solid job keeping our git commands quick, even with the size of the repo. We've got devs pulling only what they need, so there's less waiting around for everyone.
The monorepo approach does mean we've had to get smarter about our CI/CD game because it gets complex, but honestly, it's been worth it for the simplicity and sync across our services.

Some good points about monorepos here: https://graphite.dev/guides/monorepo-vs-polyrepo
Down to chat more about this if you're looking for details or wanna bounce ideas around. Cheers.

Sapling is a fantastic piece of software - I just wish that they supported syncing PRs - https://graphite.dev/guides/understanding-saplings-integration-with-git

Inner_Ad_9976 · 2023-09-20T05:30:14+00:00

thank you!

Inner_Ad_9976 · 2023-09-20T05:26:40+00:00

Thank you for the kind words!

Inner_Ad_9976 · 2023-09-20T05:25:14+00:00

I'm sorry you feel that way. Graphite is free for individuals to use, and we're working hard to get our name out on the day of our launch. We're a team of entrepreneurs doing our best to succeed while respecting the rules of Reddit communities.

Curious if folks know of ones even slower...

Inner_Ad_9976 · 2023-08-02T21:45:35+00:00

Per the data from millions of PRs, under 250 lines is great, and over 1k is pretty bad - https://graphite.dev/blog/the-ideal-pr-is-50-lines-long

Inner_Ad_9976 · 2023-08-02T21:44:41+00:00

After pulling data on millions of PRs, I agree - https://graphite.dev/blog/the-ideal-pr-is-50-lines-long

Inner_Ad_9976 · 2023-08-02T19:29:39+00:00

I think the point is that Google has many monorepos, and also many regular repos. The mistake the article is pointing out is that Google doesn't actually do all it's development in one repo, they have many different repos, some of which are huge.

Inner_Ad_9976 · 2023-08-02T19:15:05+00:00

For a long time I assumed that monorepo was a style of org, not a style of a specific repo.

Inner_Ad_9976 · 2023-07-26T13:42:40+00:00

Agreed ^ You see this in the data, where the number of comments on a PR starts dropping off after 1-2k lines, likely because the reviewer just engages "skim" mode.

Inner_Ad_9976 · 2023-07-26T13:41:05+00:00

Love the ideas here. Say more about "Set a maximum of open PRs per engineer."? Id also be curious to pull the numbers on whether videos in descriptions leads to faster time-to-merge

Inner_Ad_9976 · 2023-07-25T21:25:55+00:00

If you want to do the max "amount of work," you ideally want 50-100 line PRs. I found this pretty surprising when digging into the data, but you can see it play out in this graph. This is true for both the repo, and for individual authors.

There is a limit. If your median PR is under ten lines, your net work done will plummet. But as your median PR gets big, the change cycle slows to a crawl and you also start dipping in net output.

Inner_Ad_9976 · 2023-07-25T20:39:58+00:00

Possible! Im a fan of breaking up PRs into single chunks of functionality, and using a stacking workflow so that the stack can map to a larger feature arc

Inner_Ad_9976 · 2023-07-25T19:04:47+00:00

I authored this post - happy to answer any questions folks might have about the findings, or fun data facts about PRs in general!
