Since I'm a little slow and it took me a minute:

SDR in this context is software defined radio.

Making a single SR-71A airworthy again is likely not the goal. The tactical need for it is no longer there and a single working aircraft doesn't add much.

Rebuilding the institutional knowledge for future supersonic / hypersonic projects, on the other hand, seems like a worthwhile target.

In the early Gemini 2 days (don't remember which version exactly) I had Gemini running as a voice assistant in my kitchen, and asked it to flip a coin and tell me if it was heads or tails. It responded with "heads". I was curious if it was actually doing something to simulate randomness, so I asked a few more times and saw a pattern: "tails", "heads", "tails", "heads"...

It continued alternating between the two until I got bored (around a dozen turns).

Unless your specific test is baked into its training, real probabilities require math and rough approximation at a minimum needs reasoning to sanity-check. Jev does neither. This isn't a new problem or anything unique to Jev.

> and because those sync everywhere, this isn't a real risk.

Do they sync between Android and iPhone devices?

Passkeys do marginally improve security against MITM and phishing attacks, but they are primarily for protecting the lowest common denominator from themselves: people who re-use passwords and/or don't use a password manager.

If you use multiple devices throughout the day, registering passkeys in all of these systems becomes a big headache with O(m*n) complexity, so putting the passkeys in a password manager is the only realistic solution. But this still breaks the login flow for a very common use case: how do I log in on a device that I don't own? With a password in a password manager I at least have the option of manually typing the password.

The biggest problem, though, is how users are pushed into it without any warning or knowledge of what they're signing up for. I've accidentally set up passkeys just by clicking an okay button a few times in the past and had to go back and figure out how to undo it after being blocked from login on another computer (which computer was I on again?).

> So of course a reasonable judicial system tried to find a way to stop this wild behavior perpetrated by a woman with self-dealing political sway.

Wow that's a lot of assumptions baked into one sentence.

Unless there's a third country controlling part of Lake Ontario that I don't know about, something is off with Google's math.

62+25 = 87%

> The chip is made using Taiwan Semiconductor Manufacturing Co.’s 5-nanometer technique, Waymo said.

It's great to see alternatives to NVIDIA chips coming up, but this really highlights the underlying bottleneck that is TSMC's dominance in the manufacturing of these devices.

I think the issue of what your average citizen can or cannot do is a relatively minor.

The bigger problem is law enforcement's use of private business as end-around to dodge 4th amendment.

Google and Apple, Verizon and AT&T, auto manufacturers, Flock, and every other business that scoops up our data has a trove of information that would be unquestionably illegal for law enforcement to collect directly due to 4th amendment protections against government mass surveillance. So, instead, the businesses conduct the mass surveillance and then law enforcement gets to access that information -- either with a warrant as is the case for Google and Apple, or with some sort agreement as with Flock.

Businesses (or individuals) that deliver surveillance data to the government, compelled by warrant or otherwise, should be subject to the same constitutional restrictions as the government itself.

"Autonomous dragnet surveillance cameras" wasn't as popular with the focus groups.

> No one expected doorbell cameras to join a mass surveillance network

Doorbell cameras were at least for individual security, initially. There's no attempt being made to market Flock as anything but mass surveillance. Surely we all expect them or their successors to be detecting peoples' faces, walking gates, and who-knows-what-else in the near future.

Reducing the portion size for junk food is probably a good thing. This is a rare case where shrinkflation may actually be beneficial to all parties.

The article clearly lays out that the take-home test was not a test of memorization, but a test of students' understanding of the class material and ability to reason about how different assumptions affect its conclusions.

> Any semblance of capitalism we have is a shambling corpse barely getting around. Do you know who pulls on all the strings of our economy, gives out student aid loans to kids who just barely graduates high school? Who controls market interest rates, and gives massive multi billion dollar contracts to Companies like OpenAI, Anthropic, Facebook, Google, Microsoft? Who approved of the printing of the 50% increase in the dollar supply in the last 5 years?

Nothing in your provided definition of capitalism precludes government control of money supply, taxation, regulation, or even government contracts.

Private ownership still owns capital goods and private decision is the primary driver of investment, prices, production and distribution in most industries. This is why we have a hard time with things that are obviously good for society as a whole, like renewable energy, efficient transportation, and low-cost housing, that don't have a competitive short-term return on investment.
