Wouldn't it be possible to float teflon balloons (without ever descending to the surface), and use those to carry a launch platform? Samples do not need to be surface samples, the atmosphere itself seems quite interesting already. And

More powerful than what? If StyroPyro can build handheld 200W+ LED laser device in his workshop [0], why wouldn't a sufficiently funded military be able to build an anti-drone laser with the same (or higher) power output? Note that his

Neon is indeed unrelated to OreoleDB, but Neon does also provide the separation of storage and compute in Postgres which GP asked about ("Postgres needs options for open-source separation of storage and compute"). A mention of Neo

It's more than just one mapping index, though. The CMU paper indicates the logical keys are either TupleID or Primary Key, while the bridged index is actually a TupleID that resolves to a Primary Key, which resolves to the actual tuple

Kinda. I think it's "just" PostgreSQL behaviour that's to blame here: On replicas, transaction commit visibility order is determined by the order of WAL records; on the primary it's based on when the backend that wr

The article states a new price of $0.00003 /1k requests, an order of magnitude lower than your indication. Maybe you have miscounted the number of zeroes, or did I miss something in the calculation?

Yes, but even if you take the first definition of the Oxford or the second of Wiktionary, then still would Mastodon be a Social Network, as it does match both descriptions.

No, not individual message boards per se, but when they're connected they are called a social network. Case in point: Reddit is called a social network. And Mastodon, by its inclusion in the fediverse, is part of that fediverse soci

This might not be enough reason for the full extent of 160ms, but I'd imagine something like, from low to higher latency impact: - Digitized music needs a DAC, and this conversion takes non-zero time (few us) - Compressed data is frequ

That relies on the ID generation to be unique, rather than unique constraints. E.g. INSERT INTO t_country (id, name) VALUES (1, 'NL') is valid and would not fail in the demonstrated database, but it would result in multiple rows w

It isn't broken per se, but the behaviour of inheritance with its many gotchas can be very surprising to a user. Like "IDs are not guaranteed unique across inherited tables" is probably not something you want from your databa

Yes, but isn't a big driver of layer costs the cost of the machines to build those layers? For patterning, a single iteration could be (example values, no actual values used, probably only ballpark accuracy) on a 300M$ EUV machine with

In that second case the string is better represented as "bytea", which has most (but not all) of the features of the "text" type.

Many DBMSs with index-oriented storage (MySQL, Oracle, MSSQL) use undo logging for a transaction's MVCC, so that for deletion the old version is put into the undo log of that transaction and referred to as an old version of the record

Yes, SQL does specify case-folding unless quoted. However, the SQL standard prescribes the case to be folded to uppercase, while PostgreSQL folds to lowercase.

Starlink operational orbits are generally >500KM high (original license "at 525, 530, and 535 km", -Wikipedia). I think it is not unreasonable to expect any debris clouds from Starlink to impact orbits from 300km to 700km for m
