    They use adiabatic coolers to minimize electrical cost for cooling and maximize cooling capacity. The water isn't directly used as the cooling fluid. It's just used to provide evaporative cooling to boost the efficiency of a conventional refrigeration system. I also suspect that many of them are starting to switch to CO2 based refrigeration systems which heavily benefit from adiabatic gas coolers due to the low critical temp of CO2. Without an adiabatic cooler the efficiency of a CO2 based system starts dropping heavily when the ambient temp gets much above 80F. They could acheive the same results without using water, however their refrigeration systems would need larger gas coolers which would increase their electricity usage.

    Gemini is just a web replacement protocol. With basic things we remember from olden days Web, but with everything non-essential removed, for a client to be doable in a couple of days. I have my own Gemini viewer, LOL. This for me seems a completely different application from torrents. I was dreaming for a thing similar to torrent trackers for aggregating storage and computation and indexing and search, with search and aggregation and other services' responses being structured and standardized, and cryptographic identities, and some kind of market services to sell and buy storage and computation in unified and pooled, but transparent way (scripted by buyer\seller), similar to MMORPG markets, with the representation (what is a siloed service in modern web) being on the client native application, and those services allowing to build any kind of client-server huge system on them, that being global. But that's more of a global Facebook\Usenet\whatever, a killer of platforms. Their infrastructure is internal, while their representation is public on the Internet. I want to make infrastructure public on the Internet, and representation client-side, sharing it for many kinds of applications. Adding another layer to the OSI model, so to say, between transport and application layer. For this application: I think you could have some kind of Kademlia-based p2p with groups voluntarily joined (involving very huge groups) where nodes store replicas of partitions of group common data based on their pseudo-random identifiers and/or some kind of ring built from those identifiers, to balance storage and resilience. If a group has a creator, then you can have replication factor propagated signed by them, and membership too signed by them. But if having a creator (even with cryptographically delegated decisions) and propagating changes by them is not ok, then maybe just using whole data hash, or it's bittorrent-like info tree hash, as namespace with peers freely joining it can do. Then it may be better to partition not by parts of the whole piece, but by info tree? I guess making it exactly bittorrent-like is not a good idea, rather some kind of block tree, like for a filesystem, and a separate piece of information to lookup which file is in which blocks. If we are doing directory structure. Then, with freely joining it, there's no need in any owners or replication factors, I guess just pseudorandom distribution of hashes will do, and each node storing first partitions closest to its hash. Now thinking about it, such a system would be not that different from bittorrent and can even be interoperable with it. There's the issue of updates, yes, hence I've started with groups having hierarchy of creators, who can make or accept those updates. Having that and the ability to gradually store one group's data to another group, it should be possible to do forks of a certain state. But that line of thought makes reusing bittorrent only possible for part of the system. The whole database is guaranteed to be more than a normal HDD (1 TB? I dunno). Absolutely guaranteed, no doubt at all. 1 TB (for example) would be someone's collection of favorite stuff, and not too rich one.

    It's a loaded term that should be replaced with a more nimble definition. A dog whistle is the name for a loaded term that is used to tag a specific target with a large baggage of information, but in a way where only people who are part of the "in group" can understand the baggage of the word, hence "dog whistle", only heard by dogs. In the case of the word "degeneracy", it's a vague word that has been often used to attack, among other things, LGBTQ and their allies as well as non-religious people. The term is vague enough that the user can easily weasel their way out of criticism for its usage, but the target audience gets the message loud and clear: "[target] should be attacked for being [thing]." Another example of such a word would be "woke".

    There is a huge difference between an algorithm using real world data to produce a score a panel of experts use to make a determination and using a LLM to screen candidates. One has verifiable reproducible results that can be checked and debated the other does not. The final call does not matter if a computer program using an unknown and unreproducible algorithm screens you out before this. This is what we are facing. Pre-determined decisions that human beings are not being held accountable to. Is this happening right now? Yes it is, without a doubt. People are no longer making a lot of healthcare decisions determining insurance coverage. Computers that are not accountable are. You may have some ability to disagree but for how long? Soon there will be no way to reach a human about an insurance decision. This is already happening. People should be very anxious. Hearing United Healthcare has been forging DNRs and has been denying things like treatment for stroke for elders is disgusting. We have major issues that are not going away and we are blatantly ignoring them.

    Hm. Checking my glasses I think there is something on the top too. I can see distance ever so slightly clearer looking out the top. If I remember right, I have a minus .25 in one eye. Always been told it didn't need correction, but maybe it is in this pair. I should go get some off the shelf progressive readers and try those.
