  • Thanks again for all the information!

    Yeah, going off grid is a whole philosophical idea in itself, way smarter to share with the grid if you’re not in some very specific situation IMO.

    I always thought that those calculations about solar was a bit bogus, like you extrapolate the earnings today over say 12 years to pay off an installation, of course it will get cheaper in the future and as more people have solar, revenu goes down too. Seems you solidify that idea!

    Today though it starts to be almost a criminally good investment… Living in an appartment I seriously think I might get one of those balcony panels this year, just gotta check out how it actually works when ju inject that into the system. We redid all the electricity so we have separate lines for about everything, will the sun powered line hop over to another one (they are after all all tied together at the central input) and how many amps can you allow to flow “backwards” like that and so on.












  • The fact that you can achieve a constant average query time, regardless of the hash table’s fullness, was wholly unexpected — even to the authors themselves.

    WTF?

    I mean first of all, the “article” is just crap IMO, like only hinting att “anazing” things. But also containing basic errors like the above. It’s like they don’t understand complexity, a constant average time on what? A specific size of a hash table? Or do they mean it scales linearly with its size? Just go through the whole table and voila you have constant time already.

    So if they did find something, it’s not well explained in the article IMO. Shame, cause those kind of things are interesting, IMO.

    Edit: looks like they “cheat” (in a good way) to “reorder” the table to get their results with smarter inserts (their ‘elastic hashing’) so to not reorder the table. If so, then it’s very smart but not groundbreaking. I’m sick and just skimmed the paper, don’t kill me.
