    Comment #49170013

    I started it 3 months ago to see if I can optimize existing algorithms and grow it up in the huge framework. Though, I develop it in private repository for 3 months, some APIs are …

    Intresting. Immovability becomes a property of the type (!Move) rather than the place (Pin), and the goal is to eventually deprecate Pin outright rather than paper over it with pin…

    >> QUERY request can be cached I have a weird feeling. Query body is encrypted by https. So CDN will not be able to cache results. In order to make it work right - whole topology o…

    I would have liked to have the checks-off delta plotted across rustc versions - the deck notes this stuff moves non-monotonically, so a trend line would say more than a single-vers…

    I ve seen already one question like that in the thread. But I rephrase it slightly sharper. Did you consider renting out you setup to vast.ai and if so, how much money it can gener…

    I still have 42k page indexed, but previously I had 20k impressions per day, past week impressions started to change. And now I have 399 impressions per 24 hours :/

    Thanks! Effect-ts is totally different tools though. It's an effect system (managing side effects, composability, error channels), while orch8 is about durable execution: your work…

    Hi HN, TBH, it is my first post here and I am nervous a lot, as I put a lot of effort into this product. I have been building http://orch8.io for past 2 months. The story started w…

    The duplicate-state collapse (hoisting the match out of the await branches like in his process_command example) is the single easiest pattern anyone can apply to existing async cod…

    I go full course with supabase, they have compatible S3 storages. So auth, db, storage in same place and pretty easy to manage.

    I would treat bwrap processes as single-use across tenants, since host-side state (allocator, FDs, namespace bits) accumulates and you can not really prove it clean.

    Comment #47961687

    The C++11 example is the weakest in the article by its own thesis. Public throwing constructor, no year check, no leap-year check, so Birthdate(0, 2, 30) constructs cleanly. The C+…

    The weak link in the argument is the "1-2 GB DRAM stays stable" claim. That tier is stable because demand sits elsewhere. If AI workloads actually migrate down-capacity at scale (w…

    I would also mention Rc/Arc is Cow -it lets you borrow by default and only clone when you actually mutate. It sits in the middle of the spectrum andsaves a lot of allocations in co…
