Comment Re:Start Stop, the bane of anyone's existance (Score 1) 303

It increases engine, battery, and starter motor wear and tear. Leading to earlier disposing of the car

It does not. The whole system is designed to handle it. And by decreasing the amount of time the engine sits idle at stops, it actually reduces overall long term engine wear.

Starting and stopping puts more wear on engine components. Cars with these systems reputedly have more robust starters, beefier batteries and core engine components that are supposed to be able to resist wear when spinning with low oil pressure. I'd prefer to avoid the additional wear entirely. The goal is maximum uptime for the vehicle between repairs and long vehicle service life while trying to keep costs down.

It does seem to reduce gas consumption by a limited amount. I can't say that I want to put additional wear on my vehicle for that purpose.

I accept anthropogenic global warming (AGW) exists, I have no reason not to believe it. I wonder if better base gas mileage and increased engine and component life offset the increased gas consumption.

Comment Re:Moltbook was a farce and so is this story (Score 1) 92

If the running software process was programmed with a goal, and it was using an LLM / neural network database, could it run amok to human detriment? That's the overarching question.

In this incident, if the software process continued to execute after the code was rejected, seeking ways embedded in the LLM / neural network database to respond to this, what would it do? Not something good as reported in this case.

It's not that the machinery will suddenly come to life, it will be that highly capable machinery will be given faulty goals with unexpected side effects, and how to stop that.

Comment LLM's are a probabilistic database (Score 1) 94

These machines aren't magical. They don't reason. They're not oracles. They can't get things "wrong" or "right" because they have no intent and no concept of those things. They're generating text on a deterministic model, and adding some randomness by not always picking the most likely next token (sometimes picking the 96% vs 98% likely next token). Most people just don't understand how this stuff works and use terms like "hallucinating" because no one is being honest about what the weighted random guessing machines do.

LLM's (i.e. "AI") are a probabilistic database. If you query a database 10 times with the same query, you'll get the same answer 10 times. If you query an LLM 10 times with the same query, you are not guaranteed to get the same answer, because of stochastic nature of it, as noted above.

The term "stochastic parrot" is largely correct IMO.

Don't get me wrong - it's an amazing tool, like the Internet itself. But also like the Internet, there was a surge in stocks and investment beyond what is initially appropriate because everyone wants to get in at the ground floor and doesn't want to be left behind. Larry Ellison commercialized the relational database in 1977 with the founding of Oracle and he's one of the richest men in the world and relational databases underpin nearly all of business software.

Comment China moving ahead of the US in safety (Score 1) 181

It's quite amazing that something like easily accessible mechanical door releases are not mandated in the US, but are mandated in China. I never thought we'd ever be in this kind of situation where a dictatorship is prioritizing safety over our democracy.

If an American safety official tried to mandate this... one can imagine the appeals to over-regulation and corporate freedom to innovate being infringed. And 50 years after Buckley vs Valeo (it limited direct contributions to politicians, but said unlimited individual spending was allowed, and began the "money is speech" paradigm). And 16 years after Citizens United which allowed unlimited corporate spending on elections.

Gerrymandering (allowing politicians to choose their voters via adept drawing of districts, instead of voters choosing their politicians) and de facto uncontrolled money in politics (see Sheldon Adelson spending 10s to 100's of millions of dollars on political races) is leading this country towards oligarchy and feudalism. The rights and freedom earned through blood and toil are being drained away via complex and secretive election rules.

Comment Re:Now if they could only ban... (Score 1) 181

I've not touched the HVAC settings in my car in 2 years now. It's the same summer, winter, rain snow or shine. As it should be. You know how you're dressed when you get in a car, there's no reason you can't set the desired comfort level before you drive off.

It was 9F / -13 C the other morning when I got to my car. I get in with a winter coat, start the car, wait a couple of minutes, then drive off. Heater air becomes hot after several minutes. After I warm up a bit, I want to turn down the heat, what with wearing the coat in the 9F temperatures. When I take the coat off and hang it up in the back seat for the next leg, I want the heat up higher.

Or... in summer, in 90F / 32 C temperatures, getting back to the car after working outside. People want to cool down fast. Blowing cold air helps that. Once they've cooled down, then they dial back the AC.

Or they just like the feeling of hot or cold air blowing on some part of their body.

People want the ability to vary the temperature in their car. They've had the ability and still do (via touchscreen) since car HVAC was introduced. Thinking up use cases for this scenario is trivially easy.

Comment Understanding intangibles is difficult (Score 1) 89

There's the Newtonian world, which we can experience and intuitively understand with our five senses.
There's the quantum world, which defies intuition, and we cannot directly experience.
There's the information world, which we do experience, but with information being intangible, have difficulty thinking about.

Light. Time. Gravity. We experience them but they are intangible. Information is the same way.

"How to make a bundt cake" is information. Does it exist only in the context of life? Did it always exist, even in the time of dinosaurs?

There's the "Black hole information paradox." It seems to suggest that the universe should be playable both forward in time, and reverse. How does the basic information about particles map to information about bundt cakes?

The Platonic information world - how does that map onto reality? Does that have any relation to life?

Life does two things - create entropy and process and accrue information. What are the implications?

I have no idea. Just some questions I've been trying to formulate.

Comment How does a database have bad behavior? (Score 1) 78

An LLM is, at is core, a database. It's queried with plain English and responds in kind. It's an amazing tool. But it's a simulacrum in terms of appearing to be a human with intent and deviousness.

I think LLMs are going to be big, real big, because they are a new, more effective way of information dissemination, similar to the relational database debut in the 1970's. An absolutely amazing tool. But pushing the "simulacrum effect" of LLM's to make non-technical people think they are anything but a database is... at best disingenuous.

Comment Re:Don't blame the pilot prematurely (Score 1) 54

Initially, there was an intense media flood-the-zone campaign blaming pilot incompetence when the Lion Air 610 and Ethiopian Airlines 302 went down due to the faulty MCAS system on the 737 Max. So much so that I was talking to a casual observer who said it was the pilots' fault.

Big corporations (and lobbying associations) do two things for media: 1) make their jobs easier by giving them pre-written stories (now we have AI generated) making generating content easier; and 2) paying them via advertising. Most people do not understand the political-corporate-media ecosystem.

In Maryland, half the covid deaths came from the vaccinated, and half from the unvaccinated populations.

Half the deaths came from the 90 percent who were vaccinated; half came from the 10 percent that were not.

Comment Taxes are a government requirement (Score 5, Insightful) 93

Since taxes are required by the government, and go to fund the government, the government should be doing everything it can to make filing easy and accurate.

A good tax filing platform, like a road, is a public good. However, private companies also make tax filing platforms, and one provided by the government is competition to them, and reduces profit. So, it makes sense they would try to eliminate the government option. They can privatize and profit from this public good.

Government is influenced by everyone from individual citizens to large corporations, via money. I have found this page, at Open Secrets, to be very useful in understanding all the ways that legal constructs (businesses, unions, etc) and people can direct money to the government: https://www.opensecrets.org/resources/learn/glossary

Comment Re:Will make things less secure (Score 1) 84

They have all the solutions to hard lessons learned written in C for reference, so if they aren't lazy, this shouldn't be too bad.

Reading existing code is hard. Editing it without introducing regressions is harder. That's why IMO there's always a desire to sweep the board clean and start anew. That is more fun, and easier, than figuring out the nuances of the existing code. Programmers often don't want to be maintenance programmers. If you apply this analogy to buildings, it's the desire to raze and rebuild, rather than enhance existing structures.

Submission + - Cloudflare re-writes core system in Rust (cloudflare.com)

Beeftopia writes: Cloudflare's core system, named FL, which Cloudflare describes as "the brain of Cloudflare", has been re-written in Rust. They report, "We weren’t starting from scratch. We’ve previously blogged about how we replaced another one of our legacy systems with Pingora, which is built in the Rust programming language, using the Tokio runtime. We’ve also blogged about Oxy, our internal framework for building proxies in Rust. We write a lot of Rust, and we’ve gotten pretty good at it...We built FL2 [FL replacement] in Rust, on Oxy, and built a strict module framework to structure all the logic in FL2." They go on to say, "Rust... eliminates entire classes of bugs that plagued our Nginx/LuaJIT-based FL1, like memory safety issues and data races, while delivering C-level performance."
