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).

...it makes sense to have a headless server operating system when you're mostly running commodity spin-up/spin-down headless servers. Microsoft's server operating system was still largely based on the idea of running on a baremetal self-contained box, even though Microsoft servers had long, long since been used in the virtual machine space. If anything they're quite far behind the curve on this.

The Novell Netware model adapted to the VM era is what makes sense, where the tools don't require logging in to the server at all in order to administer the environment.

I'm not so sure about the UI. The history of Microsoft and UI for the past 40 years is that they're happy to abandon their incumbent UI for different. We saw that with Windows 3.x to '95 and NT4, with Windows 98 and the integration of Spyglass Mosaic Internet Explorer, with the transition from Windows ME and Windows 2000 to Windows XP, the subsequent further transition from XP to Windows 7, and the rework from Windows 8.x to Windows 10. We even saw it with Windows 10 to Windows 11.

They change their UI because their customers don't see the OS being new/different unless they change their UI. If the UI looks the same then the average untrained end user doesn't know the difference and doesn't see a value in spending the money to upgrade.

I have no complaint with the idea that most students simply won't be able to achieve an A-grade if the material is both challenging and taught to proper standards, but I have a major problem with the notion that teachers are required to deny students that have mastered well above 90% of the material an A-grade because other students managed to yet outperform them. I hate the idea of grading on a curve. One should be judged against the mastery of the material, not comparatively against other students during that particular semester.

That said, I have also had college classes where I really should have failed the class but because of the curve, I got an A because I had the highest scores. While some of that reflects upon me, a good chunk of that reflects upon the instructor, the department and its head, and the curricula for that particular course. If students are to be held to high standards then instructors should likewise be held to high standards, and so should their institutions. If they cannot produce results then that should reflect both upon them and upon the revenue they receive in tuition.

It isn't colonial, it is industrial. The current format of school is that of preparing for a factory workforce. We are post industrial, knowledge/AI/Whatever it will be called workforce.

Educators need to come to grip with getting EVERY child their MAX educational value we can. This means breaking the rows and columns of desks in a classroom, and getting kids their most valuable education they can get. This means some will do much better than others. Talent has gradations. Not everyone can be a Astro Physics expert.

I spent 20 years working in K-12 in a suport role. The issues vary greatly across population densities and social and economic status. The large district I worked for (~55,000 students) featured everything from schools where every kid must be prepared to go to college, to trying to arrest the pregnancy and dropout rates.

The problem is when education is treated as a monolithic bloc. Issues vary incredibly widely from school to school, from neighborhood to neighborhood. An additional problem is the attack stemming from the anti-tax crowd on public education, eroding budgets and thus paychecks, generating disrespect for teachers, and causing many to leave the profession for something that pays better. That leads to erosion of the system and it starting to break down.

I didn't really use Works, but I supported enough PCs that had it that I had a lot of exposure to it. I didn't use it because the file formats for it were annoying when I had access to Office.

It was pretty common OE software on new computers too.

If I didn't have access to Office, I tended to use WordPad. It was nearly always good enough honestly.

That's plausible.

I still hate it though. My first version of Office was 4.3, which included Word 6.0 and was ostensibly for Windows 3.1. I'd previously used Clarisworks on Macintoshes in school and before that I used a ghetto cheap program that called itself a word processor but was more of a glorified text editor in MS-DOS that worked well with an Epson dot matrix printer's formatting, so for me Word was great. I felt like the bumpers from Clarisworks had been removed, I had a lot more control over what I could do to a document.

Ribbon feels like they decided that power users didn't matter, and also corresponds with the end of the free Wordpad light-duty word processor and long after Microsoft Works was killed off.

They seem to have forgotten why some of their most popular applications became most popular in their respective categories, and that wasn't just leveraging their OS marketshare OEM install dominance. It was a combination of reasonably good UI design that had a degree of intuitiveness along with fairly easy access to more advanced features, with an added dash of the ability to use data from one application in another without major headaches. Arguably MS Office in the days before Ribbon and Metro UIs exemplify this.

Unfortunately they chose to change the UI for change's sake, ie, because users wouldn't recognize that they now had a shiny new version of the product if they didn't flagrantly change the UI, and they chose UI designs that frankly sucked. They also seem to have harmed that interoperability by trying to push too much of it when it doesn't fully work right.

Obviously there have been software companies that had products that for the professionals constantly using them were better, like WordPerfect to Word, but those didn't generally work well for both the power user and the casual user. Originally Microsoft had managed to bridge that gap. But Ribbon and Metro interfaces have harmed the power user, it's now harder to do things than it should be, and power users have incentive to look for software that gives them the features without the bloat.

I doubt that Microsoft is going to understand this in this revamp. They're going to try to cram some UI change solely for the purpose of making it different than the prior version, and even if it's now "native" it's still going to suck. And they're going to try to force any remaining users on prior versions of Windows off of those and onto Windows 11.
