Comment Re:Integral layer of the Trusted-Computing/DRM sta (Score 1) 34

Every time people hear what it actually involves is outrage and opposition, at least all the way back to when Intel first announced that they wanted to hardcode identity numbers inside CPUs in 1999. But the corporations involved have been relentless, and have sunk countless billions of dollars steadily forcing it forwards, and building front organizations to obfuscate and whitewash it.

With Windows 11, Microsoft was finally able to FORCE Trusted computing hardware into every new computer. Not just every new Windows computer, but every computer.

Every new Intel PC CPU has built in Trusted Computing enforcement hardware. Every new AMD PC CPU has built in Trusted Computing enforcement hardware. Every new ARM PC CPU has built in Trusted Computing enforcement hardware. The only processor lines that DON'T have it are the microcontrollers.

There are some unlocked smartphones available, but as far as I can determine it's literally impossible to buy a smartphone that doesn't have hardware trusted computing built in.

I specified that enforcing Trusted Computing at the internet access level is still a long term goal, they couldn't get away with it today. However they are well on the way to success. Virtually all new hardware supporting trusted computing, all the front groups rolling out standards and systems, and as it gets incorporated into things everyone is going to increasingly running into situations where they get locked out of stuff if they're not Trusted Computing compliant. Streaming already restricts you to the worst quality if you're not compliant, and it's only going to get worse as pre-Win11 computers fade out and as more things require it.

I'd hardly call exact date of birth "low information content".

And yes this does reveal exact date of birth, regardless of the bullshit obfuscation that it supposedly only reports age range. The server simply tracks the reported result every time the user connects, and on some specific day the result CHANGES to announce their date of birth.

Comment Integral layer of the Trusted-Computing/DRM stack (Score 1) 34

This is based on SLSA (Supply-chain Levels for Software Artifacts), brought to you by the same fuckers making Trusted Computing and the TMP (Trusted Platform Module). It's part of the same shitstack to prohibit you from altering your software and to lock you out of your own files, and to send spy reports out over the internet so you can be cut off if you "fail" the Trusted Computing check.

The software can use a TPM's (Trusted Platform Module) Sealing function to encrypt your data such that it's impossible to access your own data if the software is modified. It can then pass control over that data only to software updates that carry a signed security certificate from Broadcom (or any other company using this system).

It is no longer open source, your system no longer works as you can no longer access your Sealed data if you change so much as a single letter of the code. Even recompile unaltered code won't work, unless you magically manage to get your build environment absolutely identical to the company's build environment and get byte-for-byte output. Even that may be impossible with the newer levels of non-deterministic compiler optimizations.

Also, with TMP's Remote Attestation feature can be used to transmit your machine's software configuration over the internet, so that you can be cut off if your system doesn't match Broadcom (or other company's) cryptographically signed certificate.

And then of course there's Network Access Control (NAC) / Trusted Network Connect (TNC). In the long term, the goal is for ISPs to use NAC/TNC to interrogate your computer for Trusted Computing compliance, and deny you any internet access whatsoever if your machine isn't compliant. Software with this sort of "security" certificate would pass inspection, while any attempt to alter the code would be detected as "tampering". You then get "quarantined". What "quarantine" means is that you are denied internet access - with the exception that you do get very restricted access which can only be used to download the approved software to "fix" your computer into Trusted Computing compliance.

Comment "Smaller than a hair" - no (Score 1) 15

If you read the article carefully, they are talking about lenses THINNER than a hair. I see several of the posts here thinking the width/radius of the lenses is this small, a reasonable mistake given the way this was written. Having a radius that small would severely reduce their light gathering ability, requiring very bright light or very dim images or very long exposure times.

Submission + - Another large Black hole in "our" Galaxy (arxiv.org)

RockDoctor writes: A recent paper on ArXiv reports a novel idea about the central regions of "our" galaxy.

Remember the hoopla a few years ago about radio-astronomical observations producing an "image" of our central black hole — or rather, an image of the accretion disc around the black hole — long designated by astronomers as "Sagittarius A*" (or SGR-A*)? If you remember the image published then, one thing should be striking — it's not very symmetrical. If you think about viewing a spinning object, then you'd expect to see something with a "mirror" symmetry plane where we would see the rotation axis (if someone had marked it). If anything, that published image has three bright spots on a fainter ring. And the spots are not even approximately the same brightness.

This paper suggests that the image we see is the result of the light (radio waves) from SGR-A* being "lensed" by another black hole, near (but not quite on) the line of sight between SGR-A* and us. By various modelling approaches, they then refine this idea to a "best-fit" of a black hole with mass around 1000 times the Sun, orbiting between the distance of the closest-observed star to SGR-A* ("S2" — most imaginative name, ever!), and around 10 times that distance. That's far enough to make a strong interaction with "S2" unlikely within the lifetime of S2 before it's accretion onto SGR-A*.)

The region around SGR-A* is crowded. Within 25 parsecs (~80 light years, the distance to Regulus [in the constellation Leo] or Merak [in the Great Bear]) there is around 4 times more mass in several millions of "normal" stars than in the SGR-A* black hole. Finding a large (not "super massive") black hole in such a concentration of matter shouldn't surprise anyone.

This proposed black hole is larger than anything which has been detected by gravitational waves (yet) ; but not immensely larger — only a factor of 15 or so. (The authors also anticipate the "what about these big black holes spiralling together?" question : quote "and the amplitude of gravitational waves generated by the binary black holes is negligible.")

Being so close to SGR-A*, the proposed black hole is likely to be moving rapidly across our line of sight. At the distance of "S2" it's orbital period would be around 26 years (but the "new" black hole is probably further out than than that). Which might be an explanation for some of the variability and "flickering" reported for SGR-A* ever since it's discovery.

As always, more observations are needed. Which, for SGR-A* are frequently being taken, so improving (or ruling out) this explanation should happen fairly quickly. But it's a very interesting, and fun, idea.

If you don't like my source then perhaps you can provide one that is better.

I just reviewed every result on the first page of Google search for: beef greenhouse climate. EVERY SINGLE ONE explains, in one way or another, that beef has a significant and grossly disproportionate impact on the climate. The Economist, Scientific American, The Guardian, Forbes, World Resource Institute, Vox, BBC, Science(published by the American Association for the Advancement of Science), Sciencedirect, the United Nation's FAO, and countless more. Take your pick. Or you could try
Environmental impact of meat production with over 200 sources cited.

Global warming in general, and the impact of beef in particular, are all way past the point where denialism requires actively avoiding and disregard wall-to-wall sources saying the same thing.

If we are concerned about the global warming impact of eating beef then I'm thinking we did so well with the big emitters of coal, petroleum, natural gas, cement, and metal refining, that we are looking to the teeny tiny impact of beef.

If you are bleeding from multiple wounds, I'm sure you know full well that was not a valid argument AGAINST bandaging the easily fixed bleeding immediately, while experts attempt to get the more severe and difficult bleeding under control.

We have not remotely halted global warming. We have barely begun to slow it down, due to decades of sabotage by denialists. The only way we can possibly solve this problem is a few percent at a time in many different ways and many different places. As all of the top Google search results explain, reducing beef consumption is the quickest and easiest thing we can do to immediately and significantly shift things several percent in the right direction. Several percent translates into years of difference, and a lower peak temperature.

As for the rest of your post, I very carefully checked and double checked. Not one sentence was remotely addressed how much impact beef does or does not have. I'm not sure why, but you spent four paragraphs 100% dedicated to arguing that your signature is false and absurd.

Beef is one of the top cause of climate change?

Yes.

I thought I'd look that up and a study from Oklahoma State University says beef production causes 1.9% of the CO2 emissions from human activity.

That's called confirmation bias. You went looking for a specific answer, you ignored all of the reliable sources and all of the evidence contradicting the answer you wanted, and you latched on to the first random thing that kinda-sorta looked like the answer you wanted.

In this case you quote a fragment about CO2, and you utterly disregarded methane. Methane is 25 to 80 times more powerful of a greenhouse gas than CO2, and beef production accounts for approximately one third of all human caused methane in the US.

Beef is indisputably an order of magnitude more environmentally damaging than any other category of food. You could buy anywhere from 10 to 200 pounds of virtually any non-meat food, eat one pound and literally burn all of the rest, and it would have less environmental impact than a pound of beef. Beef is obviously only one of many contributors to global warming, but it is a significant factor.

Global warming is not remotely "solved". Temperatures are rising, we haven't stopped the increase, we haven't even managed to slow the increase. Temperatures are still on a basically straight-line increase. There are various initiatives to eventually try to get things under control, but we're nowhere near achieving that. Temperatures are going to continue to rising for decades to come, because denialists have spent the last decades devoted to sabotage.

Comment TRUSTED COMUPTING (Score 1) 195

Quoting the technical specifications: ...FDO software client is installed on the device.
A Root of Trust key (RoT) is also created inside the device to uniquely identify it. This RoT can take the form of cryptographic keys built into the silicon processor (or associated TPM)...

"TPM" is Trusted Platform Module. The "Root of Trust" is is the master security key locking the cryptography on the device - a key which are are explicitly forbidden to know or control. And of course this is the keys locked in the device must "uniquely identify" the device.

The Trust module is now being embedded inside new CPUs.

If you do not activate the Turst system, and given master control of you computer, you are locked out of the system, and locked out of any website based on the system. The next step is that you must register the unique identiy with a CetrificateAuthority/RendesvousService, and prove that the computer is secure against you. This is called "Trust" - specifically your computer is Trusted not to give you your keys, your computer is Trusted not to permit you to use those keys except as defied by them.

If you are not using an approved Operating system, you are locked out. If you have made any changes to your operating system, you are locked out. If you have not installed mandatory-updates from the operating system provider, you are locked out. Locked out of the system. Locked out of all websites based on the system. Locked out of any and all of your own files which were downloaded under this system. It's a Master DRM which owns your system, Trusted to be secure against the owner.

In case anyone hadn't noticed, Microsoft has made Trust chips (or Trust CPUs) mandatory for Windows 11.

There was outrage when Trusted Computing was announced, but they just quietly kept rolling it forwards. Baking it inside most new CPUs now. Some people tried to dismiss or deny or as hypothetical or paranoid or a conspiracy theory. Here it is, mandatory for Windows 11. And being forced out by Apple, and Google.

By the way, one of the earliest declared purposes for Trusted computing - given in a world cybersecurity forum keynote speech by the U.S. head of cybersecurity - was to force out operating system updates to protect against viruses and worms. Specifically, you would be denied internet access if your computer did not have the latest Opearting system updates. And of course, you would be denied internet access if your computer had an unapproved or unknown operating system. Microsoft built this - it's called Trusted Network Connect. Of course they're not stupid enough to roll that out - not until Trust is already mandatory in all common modern computer and phone hardware.... and inside CPUs... and major operating systems... and of course they wouldn't do that unless major websites were already making Trusted Computing mandatory. Oh wait that's what this story is announcing, making Trusted Computing mandatory in place of website passwords.
