I’d never realized how convenient/natural a joystick is for adjusting your side mirrors. I’m not even sure my wife has the reach to both press a touchscreen in the center console and have her head in driving position to adjust the mirrors with real time feedback. Even I’d hate to have to tweak a mirror while driving with a touchscreen.

The implication is that it’s your own blood, but I like the planning/forethought. I think you’ll be going places. Probably at a run.

And, unlike engineers in manufacturing whose deep-pocket corporations bought an exemption, Engineers in the A/E/C field are licensed. And if you screw up you can lose your ability to work in your field…forever.

Feel the hate. Let it flow through you.

Not to defend them or minimize the corporate stupidity, but it sounded like there were less than 100k people affected out of tens of millions (100m?) accounts. I get that it was a big deal for those affected, but a 0.1% outage doesn’t seem “major”.

The description of an unexpected/(impossible) orientation for an on road obstacle works as an excuse, right up to the point where you realize that the software should, explicitly, not run into anything at all. That’s got to be, like, the first law of (robotic) vehicle piloting.

It was just lucky that it happened twice as, otherwise, Alphabet likely would have shrugged it off as some unimportant, random event.

I would prefer they brought back the actual shipping part. Not this $169/yr for “best effort 3-10 days depending on our mood” they want me to pay for.

On the flip side, global banking processes something like 5+ orders of magnitude more transactions than ETH, so even at the low end it’s 1000x more efficient than the most well known POS coin.

You could say the same for a finite element model. A junior engineer with just 4 years of training can solve, explicitly, the deflection at the center of a slender, simple-simple beam of prismatic section and produce an exact (if slightly incorrect) answer. Building a FEM of the same can solve the problem and take longer (to make the model) with similar accuracy, both of which are good enough for design work.

Only a fool wouldn’t have a FEM around though, as it can solve problem that would take centuries for a human to solve. They may as well make a cartoon with the child digging a 3” hole in beach sand and then showing a backhoe making a jagged edged hole of the same size.

What’s worse is when you think there’s a discussion starting because it’s “hot” and there’s a comment thread started…only to find that the only comment in the body is the summary bot.

I’ve yet to find a modern use for usenet as I’m not in the habit of downloading everything as it comes out, nor of looking for content within a few days of release. Often I’m looking for 2-5 year old content or back catalog, and usenet has been a uniform landscape of incompletes, even with two blocks on independent providers (or they were when I bought the data blocks).

It’s a link bot. the Reddit refugees felt it necessary to write bots to link spam lemmy so it felt busy here.

Prime used to mean something. Guaranteed 2 day shipping with no minimum for no extra charge. $5 for next day shipping. Then next day disappeared. Then the 2 day guarantee disappeared. Then delivery times were in the 3-5 day range for most things. Then, in my university town, around the time of students returning to school for terms it would be 1-2 weeks. I’m not paying an ever increasing annual fee for that.

[Raises hand]

I don’t have time to fuck with managing a seedbox to make ratios and community participation bullshit (looking at you, abt). I don’t even have time to fight incompletes on a usenet block. Let me drop a Benjamin in your “donation” box every couple of years and I’ll cover part of the server as long as I can find what I need, when I want it, in the quality I’m looking for.

I have subscriptions to a few of the big boys through legal cross-marketing deals; it’s still better to know that my shows will be waiting for me on my server if and when I ever get around to watching them.

If I spend half an hour to find an implement a workaround (because finding ways around YT’s advertising is not my hobby) then I’d have to watch 60 unskippable 30 second ads to break even, every single time they upgrade their cat-and-mouse. I don’t watch that much youtube in a month, probably not in 3 months.

Any braking without energy recovery is wildly wasteful. Public transit (busses, trains) are fucking terrible wastes of energy due to their large mass and frequent stops. Hybrid and/or electric busses are, in this respect, potentially far superior to their diesel counterparts. I’m not a train person (engineer…train…haha) but I don’t think even the all electric trains use regenerative braking and there are few battery powered trains in service.

I’ve spent the last year altering my driving habits when I can. I try not to be an asshole when others are around/in traffic, but when I’m not pressed I will coast to a stop as much as possible (esp uphill) and use hills to gain momentum. Over 6000 miles, I’ve raised my overall mpg around 18%.

Not quite. EVs can still do door to door transport, are faster portal to portal, and have a vastly more diverse infrastructure, including the ability to (at least in a limited extent) traverse areas without track or road infrastructure. Public transit is still better, especially for rail, in reducing energy losses due to wheel deformation, reduction of human fatigue and dependence on attentiveness, and in some cases station to station speed and net air resistance per passenger mile. Since this is technology instead of fuckcars, it seems reasonable not to circlejerk too much.

In traffic, the largest reduction of efficiency comes from accelerating and the braking. You use energy to start moving (proportional to m V^2) and then you dump that energy into heat in your brakes to stop. The second comes from idling where you use energy to keep the engine rotating. As others have mentioned, EVs use regenerative braking so a substantial portion of the energy used to slow and stop the car is used to recharge the battery. EVs have no need to keep an engine running so unless you’re running the a/c there are minimal demands on a stopped/idling EV.

On the highway, you have the internal friction in the drivetrain to overcome, the constant deformation of the tires, and - most importantly - wind resistance, which is proportional to cd x rho x V2.

Cd (drag) and rho (air density) are low, but that V (speed) squared means driving at 75mph incurs 25x the energy use as driving at 15 mph. An EV gets no sage harbor here - plowing through a fluid (air) is essentially the same work.

To give you a sense of numbers, my vehicle (F150) gets less than 10mpg the 5 miles to my local pool/gym. The speed limit is 25 mph but there are stop signs every block or two. Lots of braking loss. On back roads with gentle curves and a 45 mph limit I get close to 30 mpg. That’s the sweet spot between overcoming transmission friction and air resistance. On the highway at 60 mph I get 22-23 mpg. At 78-79 mph I get 19 mpg. These are all generally on flat stretches using the 6 min average on my dashboard.

(Sorry for the long post…I’m an engineer and mechanical efficiency and aerodynamics are my happy place)

Re: reasonable levels - You can have fail safe or fail secure. Those are two mutually exclusive options. Locking people out of content, whether it be consumers or a partner organization (like a theater) is the price of security (fail secure).

There is no condition where mild DRM is valuable to anyone. For consumers it constitutes a hurdle to use of content they have purchased without hindering non-purchased copies from being reproduced and distributed. No DRM allows the latter; unbreakable DRM ensures the former will be substantially affected at some point.
