  • Do they “give high rankings” to CloudFlare sites because they just boost up whoever is behind CloudFlare, or because the sites happen to be good search hits, maybe that load quickly, and they don’t go in and penalize them for… telling CloudFlare that you would like them to send you the page when you go to the site?

    Counting the number of times results for different links are clicked is expected search engine behavior. Recording what search strings are sent from results pages for what other search strings is also probably fine, and because of the way forms and referrers work (the URL of the page you searched from has the old query in it) the page’s query will be sent in the referrer by all browsers by default even if the site neither wanted it nor intends to record it. Recording what text is highlighted is weird, but probably not a genuine threat.

    The remote favicon fetch design in their browser app was fixed like 4 years ago.

    The “accusation” of “fingerprinting” was along the lines of “their site called a canvas function oh no”. It’s not “fingerprinting” every time someone tries to use a canvas tag.

    What exactly is “all data available in my session” when I click on an ad? Is it basically the stuff a site I go to can see anyway? Sounds like it’s nothing exciting or some exciting pieces of data would be listed.

    This analysis misses the important point that none of this stuff is getting cross-linked to user identities or profiles. The problem with Google isn’t that they examine how their search results pages are interacted with in general or that they count Linux users, it’s that they keep a log of what everyone individually is searching, specifically. Not doing that sounds “anonymous” to me, even if it isn’t Tor-strength anonymity that’s resistant to wiretaps.

    There’s an important difference between “we’re trying to not do surveillance capitalism but as a centralized service data still comes to our servers to actually do the service, and we don’t boycott all of CloudFlare, AWS, Microsoft, Verizon, and Yahoo”, as opposed to “we’re building shadow profiles of everyone for us and our 1,437 partners”. And I feel like you shouldn’t take privacy advice from someone who hosts it unencrypted.


  • It sounds like nobody actually understood what you want.

    You have a non-ZFS boot drive, and a big ZFS pool, and you want to save an image of the boot drive to the pool, as a backup for the boot drive.

    I guess you don’t want to image the drive while booted off it, because that could produce an image that isn’t fully self-consistent. So then the problem is getting at the pool from something other than the system you have.

    I think what you need to do is find something else you can boot that supports ZFS. I think the Ubuntu live images will do it. If not, you can try something like re-installing the setup you have, but onto a USB drive.

    Then you have to boot to that and zfs import your pool. ZFS is pretty smart so it should just auto-detect the pool structure and where it wants to be mounted, and you can mount it. Don’t do a ZFS feature upgrade on the pool though, or the other system might not understand it. It’s also possible your live kernel might not have a new enough ZFS to understand the features your pool uses, and you might need to find a newer one.

    Then once the pool is mounted you should be able to dd your boot drive block device to a file on the pool.

    If you can’t get this to work, you can try using a non-ZFS-speaking live Linux and dding your image to somewhere on the network big enough to hold it, which you may or may not have, and then booting the system and copying back from there to the pool.










  • There are a lot of missing steps people don’t really understand yet R.E. how this all amounts to something complicated like “a liver”. But we think that the basic building block of it is that there are gradients of chemical concentration that some cells set up, and then other cells react to the level of the chemical and decide to different things. There’s a famous analogy of the French Flag Model, where the different stripes of the French flag are imagined to emerge from how far you are from the left edge where a “morphogen” chemical is coming from, because cells detect and react to different concentrations of the chemical in different ways.

    And the cells do these things because the DNA programs them to do it. Some genes produce proteins that can turn around and bind to the DNA that encodes other genes, and make those other genes produce more or fewer proteins of their own. Proteins can be made so that they bind or unbind DNA in the presence of other proteins, or particular chemicals, or which can function to turn one chemical into another. So you can have little logic circuits made out of genes that measure chemicals and turn other genes on and off. And you can have little memory circuits based on which genes have things bound to them and which ones are currently on or off, so the cells can remember what it is they decided to be. And so the cells are programmed to differentiate into progressively more specific cell types over time depending on what signals they see, with the morphogen gradients or combinations of them allowing the cells to have some idea of where they are in the body.

    And the proteins are these little squishy clicky things, like long strings of magnets that will snap into certain shapes, or that can swap between a few shapes. They can be shaped so they fit really nicely against certain shapes of DNA sequence or other proteins, or so that they fit really nicely against small molecules with a piece pushing on the molecule in just the right place to make it easy for an atom to break off the end of it or whatever. And because they live in this weird tiny world where everything is constantly vibrating around and banging against everything else (because of how tiny the volumes get when you shrink the lengths to cell size), this is enough for them to find and stick to the stuff they are shaped to stick to.

    Then depending on genetic variation between people, the proteins involved can e.g. have different set points for the concentrations they react to, and that can translate into the threshold between cells deciding to do one thing or another moving around in the body, and in turn translate into people having e.g. a wider or narrower region of their face decide to be a nose.






  • You’re probably going to run into the problem that people didn’t anticipate your strategy if you try to run a model on a GPU with way more memory than the host system. I’m not sure many execution frameworks can go straight from disk to GPU RAM. Also, storage speed for loading the model might be an issue on an SOC that boots off e.g. an SD card.

    An eGPU dock should do CUDA just as well as an internal GPU, as far as I know. But you would need the drivers installed.
