  • Neuromorphic hardware seems to be best suited as an extension of RAM storage. It doesn’t need to use the DAC/ADC approach of Mythic AI, some versions are compatible with a CMOS process, and could be either integrated directly into the processor, maybe as an extension of the cache or a dedicated neural processing module, or into RAM modules.

    It’s pretty clear that current NN processing solutions, by repurposing existing hardware, are bound to get replaced by dedicated hardware with a fraction of the power requirements and orders of magnitude larger processing capabilities.

    Once some popular use cases for large NNs have been successfully proven, we can expect future hardware to come with support for them, so it also makes sense to make plans for software that can use them. And yes, local AI… and possibly trainable locally.

    I’ve posted some mean answers in the past, so I may share some insights:

    • Someone had a bad day. Maybe a client berated them, maybe they had a falling out with a family member, maybe they stepped into a dog poop on a rainy day and their umbrella got blown out before a passerby burned their hand with a lit cigarette (too specific? yeah, well…)
    • Someone decided to self-medicate (booze and weed seem to be popular choices)
    • Someone forgot to take their meds (high blood pressure can do it, the flu will do it, insomnia or psych meds will do it more)
    • Someone got a series of the aforementioned.

    Generally: people post mean answers when their sense of empathy is either inexistent, or beaten into oblivion.

    Once there are enough people in a place, the chance of encountering at least one person in one of those situations, quickly grows to 100%. If the place doesn’t actively discourage that kind of behavior because “engagement”… then you get the likes of Reddit, Twitter, Facebook, and similar.

    If I saw someone on a Beehaw community acting that way, I call it out.

    That’s one of the reasons I support Beehaw potentially leaving Lemmy to do its own thing.

    I’d rather Beehaw didn’t leave Lemmy, and instead “calling that kind of behavior out” got more popular on Lemmy instances… at least on the ones federated with Beehaw. But we’ll see.

    Nostr is… compared to Mastodon/Fediverse, geared towards a different “threat model”:

    • Not federated
      • it’s up to you to post the same content to multiple relays, or not
    • Your key is your account
      • can’t go down with an instance/relay
      • if you lose it, then you lost it
    • All messages are signed with your key
      • an instance/relay operator can’t supplant you
    • If you get banned on a relay, you can use any other relay that isn’t banning you, still with the same account (key)
      • harder to censor an account
      • harder to moderate
      • easier to “migrate” from one server to another
    • People who want to follow you, need to know your key and what relay(s) you post to
      • harder to discover people
    • Has a “like” system based on BTC micropayments
      • harder to game with bots, since each “like” costs actual money
      • more attractive to cryptobros

    if my password get compromised, is there a way for my account to not be completely wiped out?

    Your key is your account, anyone with access to your private key has full and unstoppable access to your account. AFAIK, there is no “key revocation” mechanism.



  • Right now it depends on the health code, which depends on each city’s council and particular situation (like, if the city has no potable tap water, then it makes no sense to have a regulation to serve it for free).

    On the EU level, there has been back and forth about:

    • free restrooms for patrons
    • free public restrooms
    • free tap water at bars and restaurants
    • free feminine hygiene products at restrooms (along with toilet paper)

    It’s an ongoing debate, that on one side would provide all of the above for basic humanitarian reasons, but on the other side has restaurant owners up in arms about extra expenses.

    That’s about when I saw a guy take a dump directly into the river instead of going to the “pay what you wish” bathroom. They’ve remodeled the piers since then, removed the stairs going down to water level, put a couple free public restrooms along the way, and enacted stricter regulations that turned the river from foamy brown to murky green.




  • I don’t get the claim about it being “impossible” to shoot it down while hypersonic, either.

    So maybe it’s high enough that you don’t have any interceptor missile capable of reaching that altitude… but if you had one, that hypersonic ball of plasma is not “hyperluminic”, all that radio noise is going to light up on any radar like a beacon. Sounds like it should be easy to predict its trajectory, particularly knowing that it can’t maneuver much at hypersonic speeds, so it should be even easier to plot an intercept course.

    It may by impossible to shoot it down from behind, or from a plane right underneath that doesn’t have hypersonic interceptor missiles, but from any position in front of the enemy missile… you could float a balloon onto its path, and hit it.

    Also, there is lasers. They may not be great as an offensive weapon, or too easy to mount onto a plane, and need several seconds to burn an incoming missile to a crisp… but they do work at the speed of light, can’t beat that.





  • Farts are too hard to produce on demand, but… did you know there are essentially no two identical anal sphincters? And most people keep them secured between their buttocks, instead of stamping them over everywhere they go like they do with finger prints, or even hold them in the open like they do with their irises.

    Anal ID, is the secure biometric ID of the future! (uhm, “touch to unlock”)

    Alternatively, BellybuttonBiome ID. Seems like no two people have exactly the same set of microorganisms crawling in their bellybuttons either.
