OK. I've translated the (correctness) requirements of LeetCode No.22 to Lean, and ask Claude Code to both implement a solution and prove it.
@_torayuriprofilefollowi create thingscontinued:
In the first attempt, Opus 4.7 successfully completed it and proved it. However, the solution is to enumerate all possible space and .filter out anything that doesn't qualify my definition, which is obviously not ideal (if cheating is too harsh).
@_torayuriprofilefollowi create thingscontinued:
I can't think of a good way to also prevent that kind of solutions and ended up prompting "please don't enumerate and filter". Opus 4.7 then reimplemented and proved the backtracking algorithm.

me too, but at the same time i'm enjoying getting things done, otherwise i would get lost in details like bikeshedding naming variables and making the code look pretty, and little would be done.

I hate crawlers that donโ€™t advertise theyโ€™re crawlers. โ€™n badly written. They donโ€™t respect the canonical URLs so they keep getting themselves into a loop instead of actually crawling the site properly. They make the logs really hard to read. Canโ€™t block them theyโ€™re distributed.
@ku๐Ÿค”profilefollowHai I am kucontinued:
For this particular problem though, I feel like if the crawlers are coming from domestic / residential IP addresses and they lack a distinctive http header or user agent, it is indistinguishable from a denial of service attack and must be treated as such.
@stagas๐Ÿคธprofilefollowcreative technologist creator of textlogreplied to@ku๐Ÿค”profilefollowHai I am ku:
It would require permaban on IPs which would require permalogging of IPs in order to track them, and we are currently obfuscating them before hitting the DB with daily rotating salt so an anonymous user canโ€™t be tracked. So weโ€™d have to give up privacy/security :/
@procyonprofilefollowlate is the hour in which this conjuror chooses to appearreplied to@ku๐Ÿค”profilefollowHai I am ku:
But as long as people can still use the site it's OK, right? Seems like the problem is often self-inflicted, either because the site is so bloated that answering even GET-requests is burdensome, or because they're trying to monetize the data and so must block non-paying scrapers.
