juancampa··on SpaceX launches Starship v3 rocket
Glad you mentioned this. I was puzzled by the starry looking background during reentry

How about companies providing Redis as a service?

Isn’t this what competition solves?
juancampa··on Tesla must pay portion of $329M damages after fatal Autopilot crash, jury says
Autopilot in an aircraft is basically cruise control, not full self flying.

Amazing! Looking forward to the egui adapter
juancampa··on U.S. Chemical Safety Board could be eliminated
The article mentions redundancy but doesn't specify what organization is claimed to make CSB redundant. I'm guessing it's the NIH since, to be fair, Vance announced an investigation into the East Palestine chemical spill five days ago: https://www.hhs.gov/press-room/nih-long-term-health-research...
juancampa··on Trump's NASA cuts would destroy decades of science and wipe out its future
Right, but that budget is enough to pay 60+ $200k salaries. I'd imagine that New Horizons is mostly coasting and there isn't a lot of new data for long periods of time.
juancampa··on Trump's NASA cuts would destroy decades of science and wipe out its future
This quote about New Horizons is puzzling

> The New Horizons spacecraft [...] reached Pluto in 2016 and is currently exploring other distant features of the system [...]. Keeping it running today by receiving its transmitted data and making sure it remains on course costs about $14.7 million a year, or less than 2% of its total price tag.

Does anyone know why this would be so expensive? A slice of Deep Space Network time must be expensive but it still sounds like an outrageous figure to me.

Honest question. Which laws?
juancampa··on Astronomers delete asteroid because it turned out to be Tesla Roadster
Agreed, if the title were "Astronomers reclassified asteroid..." there's barely any reason to click on it.
juancampa··on Amazon S3 now supports the ability to append data to an object
Isn't it cheaper than normal S3 though?

> S3 Express One Zone delivers data access speed up to 10x faster and request costs up to 50% lower than S3 Standard [0]

The critical difference seems to be in availability (1 AZ)

juancampa··on Launch HN: Regatta Storage (YC F24) – Turn S3 into a local-like, POSIX cloud FS
One more question. How does it handle large files that are frequently modified in arbitrary locations (like a SQLite file)? Will it only upload the "diffs" to S3? I'm guessing it doesn't have to scan the whole file to determine what's changed since it can keep track of what's "dirty".

I ask because last time I checked, S3 wouldn't let you "patch" an object. So you'd have to push the diff as separate objects and then "reconstruct" the original file client-side as different chunks are read, right?

We're also interested in SQLite shared by multiple processes on something like Regatta but my concerns are the issues described in the SQLite documentation about NFS [1]. Notably "SQLite relies on exclusive locks for write operations, and those have been known to operate incorrectly for some network filesystems."

That’s the point of using a NN. If it detects people, dim it (losing contrast). If it detect bright vector graphics, invert it (not losing contrast).
juancampa··on Y Combinator Compensation Numbers
409a value is determined by an independent appraiser though, not the market. And in my (very limited) experience the actual difference can vary wildly, especially since the appraisal happens only once a year.

juancampa··on Braid, Anniversary Edition trailer [video]
I think you're thinking of someone else.

Here's the developer's wikipedia page: https://en.wikipedia.org/wiki/Jonathan_Blow

He created The Witness after Braid, which is another excellent game. He's been creating his own programming language for the past few years called Jai.

If you just keep it alive, it occupies land. If you kill it, it will decompose. Hence the burying, right? Or am I missing something?

These days Axum is the most common way of building an HTTP server. It sits atop Hyper and it’s very composable thanks to Tower. It supports Websockets out of the box too.
