Ironically, we can thank Elon Musk for that too.

edit: Gross that you're being downvoted. HN crowd needs a serious look in the mirror.

Which hasn't yet been proven to be either technically or economically viable, even on paper. It's a pipe dream.

The cynical viewpoint is that this is Elon capitalizing on current datacenter hype to inflate SpaceX's valuation based on theoretically overcoming tremendous amounts of hard physics problems, over the next 5-10 years. As he did with FSD, Boring Company / Hyperloop, Twitter, etc.

I don’t disagree with your point, but there is still value in having unit tests that change along with the code. It’s less than a “proper” test, but when these tests break _unexpectedly_, it’s still more signal than you’d have without them. Like, always changing `file.go` alongside `file_test.go` may be acceptable if you catch errors that impact `serve_test.go` unexpectedly.

Of course, if you’re just watching Claude changing both and saying “LGTM” then it’s not very valuable.

I would rather my reports tell me to fuck off than to generate something telling me to fuck off in polite but insincere terms full of emojis and em dashes. Honesty is valuable.

New comment by fcarraldo in "SQLite is all you need for durable workflows"

It sounds like you’re running this mostly on a single machine? Temporal gets much more complex with scale. Cassandra isn’t fun to manage. Ringpop and TChannel are hard to debug when things go wrong. The SQL backend support doesn’t support horizontally scaled replicas (just single instance) due to consistency requirements. Depending on how your code is written, modifying code baked into workflows becomes complex, as anything that modifies the history event ordering breaks determinism in already-deployed workers.

We use it heavily and everyone who started on it doing simple scripting/automation all love it, everyone who built real production systems on top of it all hate it. Possibly operator error, but my experience hasn’t matched the rosy picture painted in these comments.

Do you think the first paragraph is enough of a basis to form an opinion from?

100 years?

In the 1920s and 1930s the US had:

- Forced labor

- Peonage

- Debt servitude

- Jim crow laws

The 19th amendment was ratified in 1920, so that barely missed the cutoff.

The US has not been some beacon of moral righteousness for the majority of its existence.

Contributors and maintainers will also be easier to find in Rust than Zig.

Zig is a great language and I want to see it succeed, but this is a prudent move for Bun.

Even if you _know_ the debit card transaction is safe, there’s no reason to risk it when a weirdo is filming you with some wild contraption.

> It's surprising to me how much LLM "personality" seems to matter to people, more than actual capability. > I do turn to Anthropic for ideation and non-tech things. But I find little reason to use it over codex for engineering tasks. Sometimes for planning, but even there, 5.4 is more critical of my questionable ideas, and will often come up with simpler ways to do things (especially when prompted), which I appreciate.

Aren't you saying here that the LLM personality matters to you, too? Being critical of you is a personality attribute, not a capabilities one.
