Off-and-on trying out an account over at @tal@oleo.cafe due to scraping bots bogging down lemmy.today to the point of near-unusability.

  • Meta’s chief AI scientist and Turing Award winner Yann LeCun plans to leave the company to launch his own startup focused on a different type of AI called “world models,” the Financial Times reported.

    World models are hypothetical AI systems that some AI engineers expect to develop an internal “understanding” of the physical world by learning from video and spatial data rather than text alone.

    Sounds reasonable.

    That being said, I am willing to believe that an LLM could be part of an AGI. It might well be an efficient way to incorporate a lot of knowledge about the world. Wikipedia helps provide me with a lot of knowledge, for example, though I don’t have a direct brain link to it. It’s just that I don’t expect an AGI to be an LLM.

    EDIT: Also, IIRC from past reading, Meta has separate groups aimed at near-term commercial products (and I can very much believe that there might be plenty of room for LLMs here) and aimed advanced AI. It’s not clear to me from the article whether he just wants more focus on advanced AI or whether he disagrees with an LLM focus in their afvanced AI group.

    I do think that if you’re a company building a lot of parallel compute capacity now, that to make a return on that, you need to take advantage of existing or quite near-future stuff, even if it’s not AGI. Doesn’t make sense to build a lot of compute capacity, then spend fifteen years banging on research before you have something to utilize that capacity.

    Meta reveals US$600bn plan to build AI data centres, expand energy projects and fund local programmes through 2028

    So Meta probably cannot only be doing AGI work.





  • I mean, it’s easy to check whether a given instance is using CloudFlare.

    $ host lemmy.world|head -n1
    lemmy.world has address 104.26.9.209
    $ whois 104.26.9.209|grep ^NetName
    NetName:        CLOUDFLARENET
    $
    

    You can browse anonymously on any instance that permits doing so, so if you just want to browse during an outage, you can do that anywhere.

    IMHO, having an account on a second Threadiverse instance isn’t necessarily a terrible idea, not just because of CloudFlare outages, but because instances do have outages for various reasons. I have an account on olio.cafe (PieFed, not on CloudFlare) and on lemmy.today (Lemmy, not on CloudFlare) because I wanted to try out PieFed, and I have fallen back to that to post before if lemmy.today has issues.

    That being said, I didn’t intentionally try to avoid CloudFlare. I mean, they’re used by a lot of major sites, and I don’t expect them to have a lot of downtime. I mean, every Threadiverse instance has had downtime for some reason or another. I’ve had Internet outages, as well as electricity outages. Not all that common or usually an extended thing, but they happen.

    UPC designed for a desktop computer

    I wasn’t really aware of this until a few years ago, but UPSes aren’t really generally designed to keep computers running through power outages. Even today, most still have lead-acid batteries (which have limited energy density and don’t deal well with being deeply discharged many times).

    They were really designed to solve two problems:

    • In a power outage, being able to shut a computer down cleanly. That means time to save documents and — back in the 1980s and 1990s — shut down cleanly, to avoid filesystem corruption, when commonly-used filesystems could become corrupt through not shutting down cleanly. They also often came with functionality to automatically shut down the computer cleanly when the UPS’s battery was getting low, if a human had not yet done so.

    • If a generator that automatically comes online in an outage is present, keeping the computer running until the generate giving it time to come online.

    This means that UPSes tend to have a pretty decent inverter, can put out a lot of power…but generally can’t store a whole lot of power. They also are guaranteed to come online quickly; I believe that it’s typically in under 20 ms, a blip that a computer power supply can handle.

    To grab a random UPS:

    https://www.amazon.com/APC-SmartConnect-Interactive-Uninterruptible-SMC1500C/dp/B077Y62GSJ

    That runs $529. It has a 900W inverter.

    It uses this battery, which is lead-acid 11Ah 12Vdc (so 132 Wh).

    To grab a random power station of about the same price:

    https://www.amazon.com/BLUETTI-Portable-Station-Generator-Off-grid/dp/B095Y6ZTR1

    That’s $500, has an 800W inverter, but has 716Wh of battery storage, about 5.4 times what the UPS does. It also has an LiFePo4 battery, which will last a lot longer in terms of cycles and dealing with deep discharge than a lead-acid battery.
