HDCP.
Wow, so the decryption happens in the monitor? Can’t the capture card replicate that?
Earlier quoted context omitted.
No, decryption keys are tightly held and inaccessible to general populations and small manufacturers and those used by illicit capture cards are regularly revoked iirc.
In regards to that, i assume that manufacturers have to apply for a cert for their device and then embed that cert, correct? Then if the device is found to be stripping HDCP the consortium can revoke that cert, but how? Sure you can do it for PCs and consoles, but are blu-ray players connected to the internet and auto-updated nowadays? Otherwise it'd be pretty easy for Chinese manufactures out of reach of the DMCA to…
Some blu-rays force you to update before you can watch them. Also, the key revocation lists can (I believe) be included in the blu-ray itself to make them work offline, too.

We have plenty of computation. A decent laptop today is a supercomputer. Terabytes of storage can be had for under $200. Locked hardware isn’t much of an issue either. Most of that either can be unlocked or there are equivalently powerful unlocked alternatives to be had. What people must seize is the network, and the network effect. Most of today’s tech empires are built on owning the hub around which everyone commun…
Largely agree with this analysis, however your claim about nvidia: > There is no way the nVidia monopoly will last more than another two years tops. I feel as if I've heard paraphrases of this sentiment for at least the last ~6 years. Is there a reason you think nvidia's monopoly is decreasing or will decrease? They have quite the lead in terms of market share for discrete GPUs AFAICT ( https://www.tomshardware.com/n…
Prior to this year AI was much more of a niche thing. It wasn't seen as the unambiguous next generation of computing the way it is now.

The sad part is that nobody really prevents us from seizing the network. It is intrinsically decentralized by design. It takes hard work to subvert this. Yet we don't do it. A sort of digital rigor mortis has descended upon the land. A comatose capitulation, complete lack of vital signs, let alone the lust for life that characterized the early period of the Web when everything seemed possible. The "network effect" is…
I am always unconvinced by the argument that one can’t leave social media because their friends are on some site. No one I know does not check their SMS and email, and doesn’t pick up phone calls. I’ve not been on social media for about 5 years now, and I have not fallen out of touch with a single friend because of that. For other reasons like moving away physically or not gaming as much anymore, but not for this. Ev…
Not being contactable the same place all group stuff is organized or info distributed is either asking others to do work for you (to send you info everyone else got automatically) or means you’re opting to exclude yourself from those activities and discussions. Less relevant if your friend/family circle doesn’t organize group activities or chat as a group often, I guess.

Who uses facebook groups anymore for things like that? Whenever I get organized info electronically e.g. wedding stuff its an email with a link to a website. Whenever something gets planned among friends its a group text. Whenever any event in town is happening and they put up a flyer about it, there will be a QR scan to a purpose built website.

I don’t understand. If you’re watching it the bits have been decrypted. Can’t you just get them from local memory?
Realistically, no. You don't have access to the device that contains the decrypted content. Of course, you could try to open up or bypass the DRM module (e.g., via the GPU driver during hardware accelerated decoding), but that won't work with a TPM module and signed kernel space. If you look at the security technologies introduced into consumer decides over the last decades, it all serves the dual purpose of securing…
Nope. Thanks to HDCP the data never hits the kernel or the host memory unencrypted. It doesn't even require TPMs or signed kernels.
The headline borrows from Marx for radical cred, but all of Doctorow's ideas are from the anarcho-liberal school of permanent impotence. He spends the first 2000 words talking about how industry bribed the government to set unjust, inhumane policies on copyright, reverse-engineering, antitrust. Then in the 2nd half, all his tech proposals have to do with alternative tech solutions: federation, mastodon, driver coop a…
China has a "WORKERS PARTY". How's that working for them? Or is that not a true "WORKERS PARTY"?

Kinda. You need access to a decryption key. The ones known to be leaked will be revoked, so you need one that cannot be revoked, because the financial fallout would be too painful. That's why WEB-DL rips are typically made using the DRM keys extracted out of very popular consumer TV models.
Alternatively you plug into the output of the decryption module in the monitor before it hits the screen?
