Hi, I came across this thread and it's something which has raised a lot of concerns for me since Google's announcement. There's a discussion of how it hurts the open-source ecosystem at https://www.reddit.com/r/selfh... and Google's announcement is at https://android-developers.goo...

I like the idea of writing free, open source utilities for others to use. Users having to jump through even more hoops to sideload, or me having to pay money and reveal my identity to Google, get in the way of this --- especially if one of the things I've thought about is e.g. writing a tool to help LGBTQ+ people find locations where they can be reasonably safe in the current US geopolitical climate. That is exactly the sort of utility where the DoJ would make claims I'm some sort of subversive "antifa threat" and demand Google release my identity to them for harassment. Plus, the time where that utility would be most useful -- if someone suddenly has to go someplace unfamiliar on short notice (e.g. getting a call that a relative who lives a few hundred miles away in MAGA territory is getting emergency surgery), having to wait 24 hours to sideload the app if you don't have sideloading currently unlocked, just to find out which rest stops are safe to stop at or not on your drive, would be incredibly unfortunate!

I'm not saying improving app security is a bad thing, and at least Google didn't pull a "We Own Everything And There Is No Way Out Of Our Grip" like they could have, but the options they provide are not nearly good enough. It seems like they only thought about (1) average uninformed users who install things randomly, (2) big commercial developers [who still can get compromised and end up pushing malware, or might even include malware intentionally: just look at LG's McAfee situation, the infamous Sony BMG CD rootkits, etc etc], (3) independent developers who have identity documents Google is willing to recognize [what about the identity document fiascos going on right now with Ukrainian towns Russia is occupying? what about areas occupied in the Middle East by various regimes? what about the way cops confiscate homeless peoples' belongings including ID cards, but you need an ID card to get your belongings back?] plus extra cash [and $25 USD is a lot in some impoverished places, limiting the ability of people in such places to help themselves by becoming app developers], (4) students and hobbyists who only need to share their app with a small group of testers [limiting your ability to test scalability!], and (5) power users who are patient. If you don't fit into the scenarios they planned for, you might be out of luck. And I recognize that the vast majority of legitimate use cases do fall into those above categories, but there are legitimate use cases which don't. They could have at least had a series of open community fora to get feedback on other use cases and plan additional options, but they did not.

It's great that they thought about a few different use cases, at least. But that's not nearly enough!

Could I find an ally to register as the "developer" and publish such an app? Sure, but is that how it *should* be? I would now be dependent on someone else to manage the Play Store listing, which limits my ability to build. Could I spread the word to people who might need such an app that they should unlock sideloading indefinitely just in case? Sure, but maybe that creates new risks for them (and -- what if the option to unlock sideloading indefinitely gets taken away at some future point? Google gets to dictate all the changes here, and users have little recourse if they disagree with the specifics of the implementation)

I just want the guaranteed ability to say "hey, what about XYZ situation, which I or a friend have personal experience with? can you provide a way to handle that?" but I don't. There's no form to fill out to request some sort of special accommodation for an unusual situation, and there probably should be. When you have billions of users, planning for the needs of 99.99% of them still hangs hundreds of thousands of users out to dry. I know trying to accommodate more edge cases isn't as profitable, and having a large enough support team to hear people out when they have an unusual need requires a ton of extra staffing, but smartphone usage has become a critical utility rather than a luxury in much of the world. Google has an immense amount of power over numerous aspects of the lives of all sorts of different people, and if they want to continue to make money from that situation, they need to be prepared to deal with the complexities of it all.

I bought a Ford F-150 XLT (the full-hybrid pickup) and was very disappointed to find that several of the features (Including Blue Cruise and navigation) were subscription-based with an initial free period of a year or so.

Other than that the vehicle is fantastic - but was very pricey when I bought it, so having to pay over and over for the features was a very annoying surprise. (They quit working rather than quit updating when the subscriptions run out.)

... a bunch of cancer progression theories based on cell culture progression had to be thrown out when it was discovered that the cultures were being contaminated by a particularly robust and aggressive cancer cell culture, HeLa, which had contaminated lab equipment like environmental chambers or survived equipment sterilization and eventually took over culture lines in labs.

Yep. Open weights is closer to having precompiled binaries only (though you can do a little bit more with open weights). All training data with labeling, plus a detailed build log including any special fine-tuning logs, is needed, especially to help show how the final weights were arrived at (since there can be randomness involved). Unless someone else can both replicate your final output plus make their own changes to it, it's not fully open source.

We're entering the exciting age of AI-powered cybersecurity attacks. I imagine it won't be too long before something like a malware worm which polymorphs to evade detection and adapts itself as new CVEs get published, able to utilize tuned edge models, shows up. Wireless IoT could mean we end up with physical "e-quarantine" zones, wherein devices keep attacking anything in radio range...

Yeah, my argument against deregulation is probably relevant here: big corporate is just big government by another name, except with even less transparency. Never fully trust any entity which has enormous power over your life; even the most well-intentioned mega-entity is still prone to accidentally ruining lives through bureaucratic oversight. So I would hope people protesting government intrusion would also realize that e.g. Facebook is a de facto global governing structure of sorts...

Though this might work for some things, unfortunately, I think it is susceptible to Nazism. "Does this video make society a better place" could get a "yes" from plenty of people who have just sat through a video telling them how $marginalized_group is the root of all evil and must be "dealt with" =/

microwave labotomy ... We just put the machine against your head here for a bit and those bad urges go away, all better.

Another poster mentioned that it's actually focussed ultrasound.

Still sounds like breaking a piece of a system by stirring the brain with a knife (lobotomy) or burning it out with heat (cauterization), electricity (electroshock) or mechanical shock (blow to the head) - just carefully focused without (substantial) damage to other parts of the brain or its casing.

Ultrasonic destruction of a piece of the brain's reward/punishment/desire/avoidance mechanism rather than persistent unwanted fat.

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.
 

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).

And a douche bag of a president who drops bombs next to schools and kills 135 kids . Should resign on the spot for that.

Look up "human shields", the practice of siting military targets among (or in or under) large collections of non-military civilians, in order to deter strikes against them or produce propaganda claims of atrocities when they're attacked anyhow.

In such situations the fault for the "collateral damage" is assigned to the side that set up the arrangement, not the side that hit it.

Nevertheless, it should be noted that the US has been trying very hard to use precision munitions and extreme military intelligence to take out military targets with as little harm to the innocents they're embedded among as possible, with impressive success. Compare the amount of collateral damage in this war to any of those conducted in the 20th century.

He's doing the bare minimum sniff test of verifying that *you* are the guy whose name is on the bookings and not someone sneaking in on someone else's name who can't even pronounce the name on your fake id.

At least in the case of people claiming to be returning citizens I've been told that they're comparing your accent to your claimed residence (or residence history).

Different words are acquired at different ages, and many are pronounced with regional variations. An expert can talk to you for a few minutes and come up with a pretty good age-map of where you lived as you grew up. An agent with a modicum of training can detect a mismatch between how you pronounce certain words and your claimed residence and pass you through quickly or keep you around and drill more deeply. (If you now live in an area with a regional accent wildly different from where you grew up it can help to answer a where-do-you-reside question with "Footown, but I grew up in Barstate".)

I presume they are doing something similar, though no doubt with lower resolution, on the world-wide level for visitors from other countries.

Yeah, I'd call that sentence more... vapid and awkward, like much corporate speech, than tortured. It's not like it's unparseable; the meaning is fairly clear -- it's just pointless in the context presented. It serves no constructive purpose for the reader, being a vague attempt to invoke a nonspecific sense of nostalgia, likely to distract people from the frustration of the shop being closed? Corporations churn this slop out with or without LLMs

Seen Youtube lately? I just watched a video on how to make nitroglycerin. Stuff like this has been available for over a decade.

Back in the days that home solar systems still mostly used lead-acid batteries - which in some cases of degradation could be repaired, at least partially, if you had some good strong and reasonably pure sulfuric acid - I viewed a YouTube video on how to make it. (From epsom salts by electrolysis using a flowerpot and some carbon rods from old large dry cells).

For months afterward YouTube "suggested" I'd be interested in videos from a bunch of Islamic religious leaders . (This while people were wondering how Islamic Terrorists were using the Internet to recruit among high-school out-group nerds.)

Software - AI and otherwise - often creates unintended consequences. B-)
