I would encourage you to think more deeply about the assertions you're making here.

I've done a fair amount of work in this space as well, specifically my main toolbox of formal verification tools in the past have been Rocq, Idris, Dafny, and TLA+, and I can say that I've come away with roughly the same set of tradeoffs as what LightMachine describes in his comment.

Current formal verification tools are often very slow precisely because they try to reduce the number of lines of code that are required to write a proof. By making proofs more verbose and more explicit, proofchecking is sped up immensely (my own experiments check out with what LightMachine is saying here; indeed I've seen even greater speedups in the range of 100-1000x).

It makes far more sense to pay a series of one-time costs in LLM tokens that reduces your compilation time from 1 hour to 1 second than to pay the 1 hour compilation cost again and again (these are not exaggerated numbers for larger projects). This is especially true because with modern LLMs, it's usually just fire and forget and let it churn in the background than anything else.

Caching and incremental compilation has a lot of limitations, e.g. for CI. This is the promise that languages like GHC Haskell have promised for a while that always gets blown away by the other side like OCaml where global compilation is just so fast that you don't have to deal with those limitations.

Stories from these domains are hidden from every list. Subdomains match too: blocking substack.com also hides danluu.substack.com. The list is kept in this browser only.

Windows

Each story opens in a window holding its article above its discussion; drag the bar between them to share the room differently. A window can be moved by its title bar, resized from any edge, snapped to a half or a corner by dragging it there, maximised, or minimised to the bar at the foot of the page. Open several stories to compare them, and switch between them from that bar. A window's Next story link reads on down the list in the same window.

A link in a comment or an article to another Hacker News or Lobsters thread opens that thread in a window too. A link to a single HN comment opens the comment above its replies.

While a story's window is in front, the Story and Discussion menus in the menu bar hold its commands: pinning, Next story, sorting, collapsing every thread, jumping to the first new comment. Each window also remembers where you were in its article and discussion, so a reload, or Back to a story that Next took you past, finds your place again. Closing a window forgets it.

The whole arrangement lives in the address, so a bookmark or a shared link brings it back, and Back undoes the last change. Moving between Hacker News, Lobsters, their lists, Pinned and Find changes only the list, and leaves the windows open.

The list

The pin at the start of a row keeps the story in Pinned, and the cross at its end hides it. Pinned can be narrowed by words in the title, site or author, by source, and to the stories you haven't opened yet, and ordered by when you pinned them, by points or by comments; the filters are part of the address, so a filtered view can be bookmarked. Scroll past the end of the list to load more. Domain filters, in the View menu, hide every story from a site.

Applets

The Applets menu in the menu bar holds three tools, each a window of its own. Replies to me takes your Hacker News user name and lists the replies to your last thirty comments and stories, checking again every three minutes while it is open, and marking what is new since you last marked them read. Look up a user opens a profile on Hacker News or Lobsters, with their submissions and recent comments, as a commenter's name in any discussion does; the bar at the top of a profile looks up someone else in the same window, and Back returns to the one before. Who is hiring? filters the posts of HN's monthly hiring threads by the words you type.

They read only what the sites publish to everyone, so none of them asks for a login, and your user name stays in this browser.

Find

Find takes any link and lists every time it was submitted to Hacker News and Lobsters, so you can read each discussion of it.

About

YAVCHN never sees your Hacker News or Lobsters login. The discussion is fetched from each site's public API; to vote or reply, follow the link above the discussion, or the arrow beside a comment, to the source's own site. Pins, hidden stories, filters and layout are kept in this browser only.
