  • Regardless of whether it's eroding trust in cryptography today, I still assert it was a reasonable choice when the term was coined. Cryptocurrency depends fundamentally on cryptography.

    just because it uses sha256 as it's proof of work doesn't make it crypto, as it was essentially picked out of a hat.

    You could probably switch proof-of-work to use some non-cryptographic primitive with similar properties (maybe protein folding?) and it would still serve the same purpose, ignoring the economic problems. I will concede that point.

    Bitcoin still cannot function without cryptography. Each UTXO is bound to a particular key pair. Each block refers to its parent using a hash. If either of those were switched to a non-cryptographic primitive, there would be no way to authenticate the owner of a UTXO, nor would there be a way to prove the ordering of blocks. Removing cryptography from cryptocurrency would make it entirely useless as a currency.

    And for the signing of transactions, are we going to start calling bank checks crypto?

    Banks existed for a thousand years without the existence of cryptography. If you removed cryptography from RCS, you'd still have the rest of the standard for messaging.

  • I hate to be that guy, but Bitcoin uses elliptic curve cryptography to sign transactions, and SHA256 is definitely in the field of cryptography. While cryptocurrency isn't purely cryptography, it is cryptography plus economics. Borrowing the "crypto" prefix, at least in my opinion, is reasonable.

  • This is a government office. A government should be able to build the technical knowledge required to keep a private signing key secure.

    I do agree that individual-to-individual cryptography is more difficult, but how often do you need to check the authenticity of a document from a friend or acquaintance, digital or otherwise?

  • Steam's new disclaimer reminds everyone that you don't actually own your games, GOG moves in for the killshot: Its offline installers 'cannot be taken away from you'
  • That's not true. You still only receive a license to play the game, you do not own it. Directly from GOG's website:

    We give you and other GOG users the personal right (known legally as a 'license') to use GOG services and to download, access and/or stream (depending on the content) and use GOG content. This license is for your personal use. We can stop or suspend this license in some situations, which are explained later on.

    Practically this means you cannot resell your GOG installer in the way you could resell a physical book.

  • The problem with copyright is that it cannot be automatically enforced. Twitter did do a trial with nft avatars, but yeah, people just got made fun of. It's possible to tie a copyright license to an NFT if you want, but copyright and NFTs serve different goals IMO.

    Anyways, I don't want to take up more of your time. Thanks for a very reasonable discussion! It doesn't happen often.

  • I'm a furry, so I'm going to use an example that is familiar to me. Apologies if you dislike furries. Also note that, as far as I am aware, the general opinion of furries is strongly against blockchain.

    So, some setup:

    • I have a character. I pay artists to draw art of my character.
    • There is a... subgroup among furries that do not get art of their own, and instead use other people's art as avatars/profile pictures for erotic roleplay.
    • I would prefer that I am the only one using my character's art as profile pictures (erotically or not.)
    • Some furries sell their characters and associated art to other furries.

    Here's how NFTs would actually be useful:

    Whenever an artist draws some art, they mint an NFT and transfer it to the character's owner. Now that owner can prove to whatever roleplay websites that they officially have permission from the artist. The roleplay websites would need to allowlist artists for this to be effective.

    You could (partially) solve this with PGP or some other non-blockchain cryptographic tool. What NFTs offer above this is that there is only one current owner. That makes it possible to safely transfer ownership of a character to someone new.

  • Oh, sorry, I wasn't intending to argue against your main point. For the most part, I agree with you.

    What I don't agree with is that the value of NFTs (as a technology) is dubious. Instead I think it's overstated.

    In the same vein as "LLMs can write Python", NFTs provide ownership information. Regardless of what some asshat pays for a picture of a monkey, the underlying technology still has merit.

  • one more shitty techbrofad down
  • I'd argue that people got way too excited about what NFTs offer. Being able to own/transfer a digital item with a standardized interface is interesting technically (and has real value, for example ENS names), but holy hell did people go all Beanie Baby on them...

    Anyone running Pathfinder Society (or other tabletop RPGs?)

    Hey Ottawa! Bit of a long shot, but does anyone here know of a Pathfinder Society playgroup in town? I'd love to find one to join. Thanks!

    Mk3s+ fails part way through detailed prints

    Hey !prusa, maybe you can help me. I have a self-assembled Mk3s+ that I put together about a year ago, but never really used because of the following problem.

    If I print on draft quality, it makes it through most prints. I've printed a dozen cubes, several brackets, and some other odds and ends.

    If I try to print on higher detail settings, however, it behaves very strangely. Most often it'll just hang, and keep oozing out more plastic. Once in a while, the steppers will keep turning and ram the bed or print head against the ends of their tracks.

    I've tried updating and downgrading the firmware, different SD cards, etc. to no avail. Support hasn't been much help either.

    Any ideas?

    Education minister believes “parents must be fully involved” if their child chooses to use a different pronoun at school

    www.cp24.com 'Parents must be fully involved' in student's decision to change pronouns, Ontario education minister says

    Ontario’s education minister said he believes “parents must be fully involved” if their child chooses to use a different pronoun at school.

    'Parents must be fully involved' in student's decision to change pronouns, Ontario education minister says

    Ontario’s education minister said he believes “parents must be fully involved” if their child chooses to use a different pronoun at school.

    The comments were made at a news conference on Monday morning, where Stephen Lecce was outlining the changes students and parents can expect at Ontario schools come September.

    They also come as Saskatchewan adopts a new gender and pronoun policy, joining New Brunswick in legislating parental consent for students under the age of 16 who want to change their given names and/or pronouns at school.

    “I think we understand though that parents must be fully involved and fully aware of what's happening in the life of their children,” Lecce said.

    “I mean, often there are health implications, and I think we have to respect the rights of parents and recognize that these can be life-changing decisions, and I think parents want to be involved so that they can support their kids. And I think that's a really important principle that we must uphold.

    Lecce prefaced this by saying that schools should be safe for all children. He noted that teachers and school boards take home environments into account “where there are exceptional circumstances” or “situations of potential harm to the child.”

    “Educators are well versed on exactly what to do and who to turn to if they believe that child may be harmed for whatever reason, or whatever circumstance,” he said.

    “But as I say, as an overarching value system, I really do believe that parents need to be fully aware, fully engaged. And school boards need to be transparent with parents. I mean, they are the legal guardians. They love their kids. They want to be aware of what's happening in the life of their children in their schools.”

    The minister would not say if this were something his government would legislate, saying only that this was the “province’s position on the matter.”

    A new poll by Angus Reid released Monday, which surveyed 3,016 Canadian adults online, suggests that about 43 per cent of Canadians believe parents should both be informed and give consent if a child wants to change how they are identified within a school setting.

    In Ontario, 43 per cent of survey respondents said parents must both be informed and give consent of an identity change, while 34 per cent said parents should simply be informed.

    About 16 per cent of respondents said it should solely be up to the child.

    The Toronto District School Board currently has a policy that protects the privacy of transgender and gender non-conforming students, recognizing that some children may not be open about their identity at home.

    It notes that a school “should never disclose a student’s gender non-conformity or transgender status to the student’s parent(s)/guardian(s)/caregiver(s) without the student’s explicit prior consent.”

    “This is true regardless of the age of the student.”

    The policy says that school staff should consult the student as to how to identify them when communicating with their guardian.

    School boards in Saskatchewan have asked the province to pause its gender and pronoun policy in order to allow for a “complete review and report” prior to implementation, arguing it could have safety risks and could violate charter rights.

    As of last week, the Saskatchewan government has not backtracked on its position.
