how do I tell git : dump all versions of file ss_web.clj for me ? (it's in git history, but it's not in current tree)
does anyone know a simple database for timeseries? I'm looking for something that is very stable, and can quickly perform queries like "what is the sum of events X with attribute Y over the last 2 hours", and requires a minimum of ops
the most important question is probably one of: do you wnat to lineraly scan all events from past 2 hours to get relevant ones, or do have some type of inverted index
depending on your needs, maybe https://www.timescale.com ? I heard of it a couple of months ago
anyone else gettng weird slack "something with websocket; please restart your browser" msgs ?
yeah, if twitter is any guide this happened to a lot of people for about half an hour
you can have a blockchain without proof of work, other proofs can work, or no proof at all if you trust eachother - but at that point it’s just an impractical database.
oh because it also has a history so it’s not just federated messages, it’s a federated archive
a blockchain-based chat app probably wouldnt be too awful as long as it can keep the transaction rate fast..i wonder if there are blockchain algos that allow you to get a digest of the current state of the world and then backfill rather than having to download everything
OK - poe’s law applies here - I hear many insane assertions about the utility of distributed services and block chains and such so I honestly can’t tell parody from earnest advocacy
i tried their web client and it was ok. i still wanna write my own at some point though 😏
what the world needs is a slack alternative built on blockchain that rewards people for generating blocks while chatting 😮
it could work, just have to figure out how to stop people from spamming to improve their chances of minting coins 😉
(and it was showing red on messaging and connections when the outage first started -- and then red on everything for a while)
hehehe, i’ve been putting it down for 2 years now. i’m a bit surprised it has spread to the extent it has now
i’ve been in the fray in UAE with all this. it’s crazy how many people think that blockchain is the miracle solution that will automate their all their processes, and no alternatives ever existed up till now.
which, i think, is being propagated by cyrptocurrency enthusiasts/investors to try to prop up their investment. If people believe blockchain is the magic elixir then it drives the cryptocurrency narrative.
it helps too to drive home this mysticism that the cryptocurrency community has developed dense and occasionally nonsensical jargon
blockchain is simply a public/distributed backwards linked list. To even call it a database is to overstate its functionality and purpose.
in my mind it’s definitely a valuable addition to computer science, but I don’t think it’s the elixir people are selling.
the unfortunate side-effect that seems to come with the mysticism around blockchain/cryptocurrency is the assumption that only geniuses can understand it. Us mere mortals are eternally bound to ignorance. And that leads to absurd statements like the one above. The guy posting that, if he was serious, doesn’t really understand what slack’s scale problems are (and I’m sure none of us here truly do either) and is just prescribing a cure out of ignorance.
Disregard the bugs that lead to hundreds of millions of dollars in theft, the Ethereum team are infallible.
right, well the people on the other end of that transaction may disagree with that assessment but the blockchain itself doesnt know the difference!
don’t forget the part money plays - there’s no proposition so stupid that you can’t convince someone to agree for money
The nice thing about blockchain is, is that it is something where a lot of people talk about it and like 99% talking about it, really dont know what it is. All they have is an imagination in their head about what they think it can do. So blockchain is kind of a personalised IT reality dream show or something like that. And of course it also has a lot of positive connotations, like being super secure + some more bullshit bingo.
yeah thats where i was going with the mysticism…it’s just sort of something people project their tech fantasies onto, regardless of how realistic that is (which is, often, nonsensical).
the super-secure thing is a red herring too, it’s just a conflation of cryptographically-secure digests vs encrypted data
yeah that’s why i’m careful to be specific about cryptocurrency vs blockchain vs cryptography because they’re all different things.
to be fair though hashing and digests come from the cryptography field, and they’re fundamental to the functioning of a blockchain, so i get the naming.
