Are you dense, man? No one said that. They’re saying that one blockchain would take several hundred DBs to equal its energy use. You’re wrong and doubling down for some reason and it’s just making you look silly.
We're not comparing millions of DBs to a single blockchain. We're comparing 1 DB to 1 blockchain instance. If you had millions of blockchains, you would use exponentially more energy for the same data vs. a normal database. Updating tables is not the same thing as hashing and validating every prior entry in the table.
The only person here who doesn't know what they're talking about is you. If you took a standard DB (MySQL or Postgres, for example) and took that same information and stored it on a blockchain instead, you'd use far more energy on the blockchain and the issue would only get exponentially worse as the chain got bigger. Normal DBs don't need to hash new entries or validate them against previous entries that are also hashed.
I think people would learn to move out of the way at that point or just use Siri to respond. That felt very much like a “first-time” faux pas when he stops on the stairs.
That’s one opinion. The other is that I like that all my devices operate seamlessly with each other and save me time and aggravation. I like that I can give my parents Apple products and not worry about them downloading things that might compromise their data or mess up their devices. The fact that limits exist is exactly what I like about Apple products. When I pick them up, they work.
I say this as a current and previous owner of multiple PCs that I built myself and multiple Android devices. I used to love dicking around with all that stuff. Now I just need it to work and I need it to be secure and reliable. I get that with Apple products. I don’t get that with Linux, Windows, or Android anymore.
You don't even understand blockchain so I'm not sure what your edit is all about. You're comparing blockchain to a database in your replies as if they're comparable.
Don’t forget Apple. Even if you don’t own any Apple products, you have to talk shit about Apple products and anyone who uses them or you’ll lose your Lemmy card. Talking positively about Apple or their products is an immediate downvote and owning one of their products is treason.
It’s AR and VR in whatever mix you want it to be. The little spinny dial at the top controls how much of the real world you see vs how much of a virtual environment you see. The bottom end is full AR, the top end is full VR.
There’s an option within control center to mirror any nearby Mac and initiate from the headset. I mirrored my MacBook from upstairs without interacting with it at all and initiated that from the headset.
The only part of this that I agree with is the “last 10 years have been toys”. The Vision is the best VR headset I’ve ever used and I fully expect it will be jailbroken or that games will release for it. I backed the Oculus kickstarter and have bought a new headset every generation since and this one blows them all out of the water.
I wore it for about an hour comfortably and tried Safari, djay, AppleTV, Encounter Dinosaurs, and then watched Thor: Ragnarok in 3D from start to finish. I was comfortable the whole time but you can definitely feel that you have something on your face and head. The only place I feel any discomfort (and it’s more of just a pressure than discomfort) is on my cheeks where the headset rests. Pretty similar to others I own (Quest, Vive, Index, etc) but it is a little heavier.
I will be working with it (content and media production) and watching a lot of movies. My wife’s schedule for work is offset from mine so being able to watch 3D movies in bed while she’s sleeping would have been reason enough for me to buy it. The other stuff is icing for me. Additionally, I didn’t know this but all my movies in my iTunes/Apple Library that have a 3D version are available for me to watch in 3D at no extra charge. My library just shows up like any other device but it prompts me to choose 2D or 3D on playback start.
I don’t anticipate this changing anything. I don’t plan on using it while my wife is home unless she’s sleeping or watching something else on the main TV in our house. We also have had other VR headsets before and our office is zoned with the Index base stations so I think my usage will start similarly to that - occasional or when I know she won’t be around. One thing that is really different already and I find cool is that the Vision detects people and highlights them in my view and then turns on the weird EyeVision thing (or whatever it’s called) so that my wife knows when I’m actually interacting with her vs whatever is on the headset. If I’m still engaged on the headset, she just sees a rainbow swirl effect until my eyes focus to her and then the Apple googley eyes pop out. We FaceTimed with it too and Personas are cool but will make you look like a sex offender for the first few minutes until the newness wears off and then it’s a decent enough approximation to be serviceable for its intended purpose.
DBs are not the same as a blockchain. A DB doesn’t have to hash all previous data before it every time the DB is written to. You can read and write to a specific spot in a DB without ever knowing anything else about the DB. With blockchain, inserts have to be successive and they have to reference every previous insert to validate that the entry series is unbroken. On top of that, for things like Bitcoin, every other client also has to validate it since the ledger is shared.
There’s a reason blockchain is significant. Otherwise, why didn’t stuff like Bitcoin exist prior to it? Databases, in some for or another, have existed for decades. Blockchains are immutable, that’s why. The order of entries matters and validation is a requirement.
Tried the Vision at the mall today, though, and it’s pretty awesome. I had an experience I’ve never had in VR yet - when shown heights, my body actually reacted as if it was real.
Guess what? I don’t subscribe to either. I cancelled Netflix after that nonsense and I cancelled Disney 2 days ago. Live by your principles. You whining like a mule on Lemmy does nothing.
100%. Capitalism is great until it reaches a peak where people who provide no value except in the wealth they’ve amassed are the ones who gain the most from it. You can succeed simply by being born with wealth and having no other value because other people who do have value will need you.
Are you dense, man? No one said that. They’re saying that one blockchain would take several hundred DBs to equal its energy use. You’re wrong and doubling down for some reason and it’s just making you look silly.
