This is so beautiful, this thread doesn't have enough praise! It's not easy to get this "right". Lovely!

Honest question which I think is at the heart of the question: What’s the difference between these and NYSE / Robinhood?

Everyone is commenting on the blog but not the service. I remain skeptical:

A. Either it will remain obscure and not see any real use

B. (Less likely) It will get abused to hell before it is shutdown.

Claims of removing violating content “immediately” seem unrealistic under decent usage, unless that $600 can grow unbounded.

The environment around the language can put in limits (on time, number of operations, etc.)

Convex does this well, replacing SQL (somewhat yaml-like sucky old declarative language) with JS/TS but in a well-locked-down environment with limits to ensure one mutation or query doesn’t take down the whole DB.

Wait, have you been using Cursor? This is exaclty what it does fairly well.

Why do ppl think building something through yaml is ever a good idea??

(I know why: for a platform it’s simpler to parse a yaml than to run code, but it’s almost never a good idea for anything that needs to scale in complexity)

The really bad:

UI is constantly inconsistent. You have to keep reloading the page to hope to see what’s up with your MR. Doesn’t help it’s super slow to load.

The backend infra is super unreliable, with actions failing to start, merge trains being stuck, their webhooks being overloaded.

If you think GitLab is a good alternative to GitHub, I have 0 trust in you.

GitLab and Azure are a daily source of pain for us.

Convex's open source version is OK as long as you don't expect huge load.

Dynamically and statically linked libs is hilarious in the context of webassembly running in the browser.

Confluence is ok and has improved recently.

Jira is garbage (frontend, backend). Tough but true.

This is the “ad tax” reasoning, but ultimately I think the answer is greater efficiency. So there is a real value, even if all competitors use the tools.

It’s like saying clothing manufacturers are paying the “loom tax” tax when they could have been weaving by hand…

It has improved massively by 2023 when I left.

Conflicts spawn most likely because PR A was squashed, and once you squash Git doesn't know that PR B's ancestors commits are the same thing as the squashed commit on main.

No idea if this feature fixes this.

Edit: Hopefully `gh stack sync` does the rebasing correctly (rebase --onto with the PR A's last commit as base)

Workflows can vary, but what I like:

PR/MR is an "atomic" change (ideally the smallest change that can be landed separately - smallest makes it easier to review, bisect and revert)

Individual commits (or what "versions" are in Phabricator) are used for the evolution of the PR/MR to achieve that change.

But really I have 2 use cases for the commits:

1. the PR/MR is still too big, so I split it into individual commits (I know they will land together)

2. I keep the history of the evolution of the PR/MR in the commits ("changed foo to bar cause its a better approach")

Also they only have dark mode in the app, even though the app is (or was) clearly not native anyway.

If you were just a little bit serious you wouldn’t be discussing this on a site run by Y-Combinator!

(the “angry” comments are so tiring)
