There's no universe where that's ahead of "commit secrets to public github repo".

Lot of people run tools like claude code in "auto" mode, where it has un-gated access to bash. This gives it access to your environment and file system, where you might have API keys or AWS tokens. Or it might be reading files like ~/.m2/settings.xml, ~/.npmrc, ~/.aws/config etc.

When you write a prompt like "Read the recent cloudwatch logs for serviceX and tell me why the 5xx error rate just spiked." There's every chance the model decided it needed to figure out how to access your AWS account, sent a series of Bash commands to the local agent to dump your env and aws config, ran a decision tree over that, and formulated a bunch of aws cli Bash invocations to gather the CW data. Those get sent back to the agent, which executes them and sends the output back to the model so it can answer your prompt.

If it's so dangerous/risky, why release it with the so-called "guard rails"? Why not remove the risky stuff?

You can't remove the the "risky stuff" because it's baked into the model weights, which are opaque and empirically derived from the training. They tried to make it better at programming and succeed, but that also makes it a better at analyzing code and finding faults. You can't pluck that capability out of the model any more than you could pluck out how to code in C from a programmer's brain. Not without lobotomizing them, anyway.

Just about everyone in a modern society is walking around with a covert listening device in their pocket: their phone. Just start the voice memo app running and stick it back in your pocket. Or just hold it in your hand. Nobody questions someone having their phone out.

You might want to read up on how current hybrid vehicles actually work, 'cause it seems you have more than one misconception going on.

I have. For instance, my latest vehicle is the Ford F-159 XLT,, the full-hybrid model of the F-series pickup truck line. Power train is:
  - 6 cylinder dual-turbo engine. (runs low power but approoximately doubles output when a lot is needed.)
  - 47 HP motor-generator "pancake" on the engine side of the ttransmission, to scavenge / return power to./from a 1.5 kWhr lithium battery.
  - 10-speed automatic transmission, working with the lithium battery;s main alternator to fine-tune match the engine/mogen to the current driving situation. Max power of engine plus hybrid mogen; 430 hp.
  - full four wheel drive.

So it's primarily a gas-engine power train with an electric-car motor mechanically coupled to the engine shaft. Many other hybrids, from the venerable prius onward, are similar, with plug-in variants having a big scavaging/peaking battery good for pure electric operation of tens of miles rather than a minute or so and a wall-powered charger added.

What I'm looking for is essentially a pure electric - totally electronic "transmission" consisting of alternator(s) between the batteries and the motor(s), plus a tiny engine-generator able to burn gas and feed some teens of KW of charging power into the batteries when running down the road or parked near it.
 

Comment cobalt chemistry, not so nice. (Score 1) 115

Do the Waymo batteries use one of the lithium chemistries including cobalt, or a non-cobalt chemistry such as lithium iron phosphate?

Cobalt chemistries have a higher power/weight and energy/weight ratio, which made them the go-to chemistries for vehicle batteries. But they also produce oxygen when the cells overheat, leading to an unextinguishable runaway fire hazard: A burning cell makes enough heat to ignite the adjacent cells, so the whole assembly of them goes. Bad enough when it's a car's worth, but a disaster if it's a shipping-container sized module of a utility energy storage site. (And even worse when the site is a building full of racks, which someone had "protected" from fire with water-spraying, equipment-shorting system, so the whole site burns up, as happened recently with one in California creating a toxic mess.)

That's why purpose-built stationary lithium energy systems use non-cobalt chemistries - heavier, but a shorted cell just kills itself without getting hot enough to light off its neighbors.

I want to see inexpensive plugin hybrids.

But not like the current ones, which are primarily an engine/tranny powertrain with a motor/generator + small battery for scavenging downhill/braking energy for later accelleration/uphill/cruise/power-boost.

I want ones that are primarily a battery-electric with a small aux engine-generator (say 15-20 HP range), big enough to power crusing with a bit left over for gradually charging. That would let you range-extend by the size of your gas tank plus fillups (i.e. indefinitely if only gas is available) or go from battery empty to back on the road in a couple tens of minutes.

The backup engine would only run at max-efficiency speed and could use an atkins-like cycle (see "liquid piston engine") to get the max power out of the fuel. Most operation would use power-grid charging (when available and cheaper than fuel).

But could DNA or a similar mechanism have evolved in the first place in a high ionizing radiation environment? Simple RNA floating around in an amino acid soup doesn't have any error checking and correction and life had to start somewhere with simpler tools. Also keep in mind we'd have a much less abundant atmosphere, if any without the magnetic field.

Comment Re:Slippery slope and all..... (Score 1) 95

Why?

I mean, seriously. How exactly is it a good thing that someone driving past a school bus with some flashing lights gets a more serious punishment than someone who crashes into a school bus and kills a few kids?

Because the kid crossing the street in front of the bus can't see the driver who has decided to zip past it from behind, and the driver can't see the kid until it is too late. It's extraordinarily dangerous to run the lights on a bus, and the kid who will be hit doesn't have the benefit of 10 tons of steel protecting them.

Accidents involving school busses have a pretty low fatality rate because the vehicle is so heavy and has so much inertia. It's far more likely the driver of the colliding vehicle will be injured. The kids are far more vulnerable getting on and off than once they are on board.

Yes, downsides to ride-sharing companies and their profits, which can impact their executives.
Not saying "wont someone please think of the..." but you are factually incorrect.

I confidently predict the biggest losers will be customers.

Good. Cab driver used to a job you could make a living at. Then ride share companies came along and "disrupted" it into a gig job. Of course once cabs were marginalized or driven out of business they started jacking their prices back up, so now everything is worse except for the Uber and Lyft shareholders.

Prices need to come up to something the workers can make a living at. If that makes things too expensive because an extractive mega corp needs to make a profit, then maybe municipalities will do something to limit them and bring in more competition.
