Is it compatible with Aurora DSQL? Or does it rely on Postgres features they do not implement?

Can this be used as an embedded lib instead of a separate binary as an API?

And am I understanding correctly that if I pointed 2 running instances of s2-lite at the same place in s3 there would be problems since slatedb is single writer?

Improved inline suggestions are under way if you search the PRs on GitHub for zeta2. You can also bring your own edit prediction provider by configuring copilot or supermaven. Codestral edit predictions were merged last week

Zed needs a full helix bindings support and helix needs plugins. Both are so close!

This would probably last forever. The MD class size is only around 120 people and at 70k per year tuition costs would be 8.4M per year (ignoring that only families earning under 300k are eligible). Modest interest on 1B would easily earn over 10M per year and probably several times that. Hedge funds often manage these endowment funds.

HN is really random, but also the submitter is an author whose posts are regularly submitted to HN and is a participant (I believe) in a trial for the drug in the article. The regular updates (and the author’s participation in threads) have endeared him to the community.

The coolest thing (IMO) compared to react is the ability to await inside a component.

Matrix Analysis by Horn and Johnson is another great book, though it is a bit pricier than a Dover book.

Thank you. It’s been a while since I read Candide and while I say “All is for the best in this best of all possible worlds” somewhat regularly, that detail has since fled my mind.

This is tangential, but was Voltaire mocking Leibniz in Candide?

Notable too that the VM it runs on Mac comes with qemu user mode emulation and uses binfmt_misc to run binaries for different architectures so obviates the need for Rosetta.

Edit: to try this out compile a “hello world” binary to say arm64 and riscv64 and amd64 and run it all in the same container (be sure to statically link)

New comment by kwkelly in "Why Are So Many Dogs on Prozac?"

kwkelly — Mon, 23 Oct 2023 02:13:29 +0000

Dogs do require work and attention and care, but there’s nothing in the article to suggest that the owner wasn’t giving the dog the exercise or attention it needed. A vet behaviorist, like Dr. Pike referenced in the article, is only going to prescribe medication for clinically significant abnormal behavior.

Medicating dogs to ease their stress or pain (physical and mental) is not abusive when practiced appropriately but should be considered compassionate. No one balks at the idea of giving melarsomine to a dog with heartworm and appropriate treatment for diagnosed behavioral issues should be the same.

It is possible it’s overprescribed though I don’t have info on that.

Unfortunately in the vast majority of cases another dog is ineffective for the treatment of separation anxiety. It does sometimes help but they usually want a human or a specific human.

Prozac as a treatment for isolation distress or separation anxiety is much more effective when coupled with desensitization training and possibly counter conditioning. If you’re not already practicing that it may help.

You would do it as a tagged template literal rather than with plain string templating, similar to Postgres.js

You have to be careful with code like the above in React. Using a lower-cased function that returns JSX but is not rendered with react.createElement (either directly or via the JSX syntax) can lead to confusing violations of the rules of hooks as it relates to exact ordering of calls.

This is because it doesn't get registered as it's own component, so conditionally called children with hooks may cause errors.
