Comment Re:I want to see inexpensive plugin hybrids but .. (Score 1) 135

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).

No. There is no bi-polarity. And the people booing you are not mentally ill.
The students hate that you think it's the greatest new thing.
And they love the time it did not exist.

To use a much overused term where it's actually appropriate:
When you try to convince people their view is invalid and they are mentally ill (bipolar), you are not merely disagreeing with them; you are gaslighting them.

Comment We kept our CAD drawings on them...for a while. (Score 2) 180

At a large US auto manufacturer our crew were responsible for commissioning controls systems and maintaining the drawings related thereto.
The HDDs on the CAD machines were simply NOT big enough to contain all the drawings so we had stacks of ZIP disks and both mobile (SCSI by parallel port) and internal (SCSI) readers for them.
One of the more experienced guys bought a CD burner (that was a $600.00 purchase at the time) and would make weekly backups for us. Blank CDs were $10.00 apiece at the time.
A couple of years into it we started hearing the "click of death". Thank you Butch; you saved our work!

Comment Re:My home network is nearly pure IPv6 (Score 1) 73

To me the hoops that smoothbrains will jump through to avoid IPv6 and stay on legacy IPv4, especially when hosting, is pathetic. NAT, port forwarding, tunnels, blah blah blah blah.

I have something like ~1.2 trillion times the number of routable addresses that the entire IPv4 space has. Not all are reachable, of course, just the services that need incoming access and they're each on their own isolated DMZ.

Comment My home network is nearly pure IPv6 (Score 1) 73

Started the move about 18 months ago when I decided to get off my lazy ass. My ISP gives out a /56 prefix, so that lets me run 256 /64 subnets/VLANs in the house, currently there are ~10 in use. Everything get a GUA through SLAAC and I use RAs (Router Advertisements) to give ULAs to everything. Any external facing services get their own VLAN and /64 for the system(s) as needed. Firewall blocks all incoming as they usually do by default and I punch a hole for the external-facing systems. They can't reach back into the network, they only answer the phone. All the systems update DNS dynamically if the prefix or full address ever change.

I have an SSH bastion set up. In all this time there has not been a single SSH attempt from the internet. On IPv4 it was constant background noice.
For those legacy IPv4-only systems on the internet, I set up NAT64. I have an IoT VLAN and IoT 2.4 GHz wireless network that are only IPv4 because a lot of IoT network stacks are junk.

I'm still farting around with it, but man oh man, there's no way I'd go back to IPv4. It was one of the best moves I've done in ages.

"kind of a big deal" the guy specifically said that it isn't. Y'know, the guy who's name makes the Li in Linux I guess that quote is included, but it kinda defeats the whole article. Weird and stupid clickbait but it's nice to see people excited about Linux.

Increasing UDP throughput simply by inlining a function is a big deal!

Comment Re:Smart TV means accessing all your private data. (Score 1) 79

The best part about smart TVs is that they DO collect your data. This supplements the price of the TV and lets you get one for much cheaper. With the money you save you can buy a streaming device (Chromecase/AppleTV/Shield/etc), ideally using this device and never even connecting your TV to the network/wifi/internet. In the end you have a cheaper TV, and you have a platform that you choose (Apple/Roku/Google/etc), and your sharing less of your data.

Sadly while your logic sounds spot on, the reality is, that TV still does ACR (basically hashing each screen sometimes multiple times a second) and builds one hell of an accurate profile of everything you watch. Even if the source is HDMI. And it's still sold.

Food for thought, that HDMI cable to your dedicated device, it likely supports networking, so the TV has a path to the internet even if you don't connect an ethernet cable directly to it, or add in your wifi creds.
