Most of the use cases for v2g don't really involve drawing massive amounts of power from the vehicle battery for long periods of time. If you want to have a solar system and have storage for use overnight on a regular basis, you'll want something better suited to do that, like a big LiFePO4 pack. Likewise you won't want to be juicing your car to 100% every day so you can run your AC overnight and still leave with 80% SOC in the morning -- v2g is simply not well suited for storage/arbitrage applications.

By contrast, v2g applications are more geared to things like emergency power, or handling demand spikes in a solar power system. Although you hear a lot of discussion about the future of grid-scale v2g applications, the fact is that is simply never going to happen. Consumers aren't going to attach their car batteries to the grid for the benefit of anyone but themselves, for exactly the reasons you have already given.

Also keep in mind that the power demands of a household are really quite modest when compared to the power demands of a EV driving around. I haven't tried to assess the economics, but my hypothesis is that the increased very shallow cycling caused by the average V2g application isn't prematurely destroying batteries and probably isn't impacting battery lifetime all that much. Lithium batteries like to do work; they just don't like being really full or really empty.

Hummer EV powerstation provides 6A 240V outlet and supports an EVSE on the outlet for v2v charging

All vehicles that have DC fast charging of any sort (essentially every EV of the modern age) are already "V2H capable" because they are able (with hardware already in the car) to bridge the main pack directly to the charge port whereupon an EVSE (Electric vehicle supply equipment) with an inverter so equipped can be cajoled to output unimaginable amounts of power. Think reverse supercharger. Yes, sir, your car is capable of delivering it's rated peak horsepower directly into the mains (appropriate power converter required).

Why haven't we already seen it? Well quite frankly it seems that the car manufactures would rather have you buy the entire concept as an overpriced integrated service that only works with "Their special equipment (TM)" instead of simply acceding to the simple idea that your car with a 400V DC battery pack and sophisticated power management system in it ought to let you plug any goddamn 400V DC thing into it that you goddamn well want to.

Well to be a little bit more honest about it, Space Force really isn't anything more than a name change for Air Force Space Command, which is currently and always has been stationed in Colorado, already has all of the facilities, equipment, and security (Under a fucking mountain) required to do it's job.

All of the space industry stuff in Alabama is political; all of it. Huntsville and its surroundings like Athens, Decatur, Cullman are extremely rural. It is not a place where anyone in their right mind would choose to open a commercial space business. The local population does not have a sufficient pool of highly skilled and educated people to fill the highly demanding positions required in that industry. The people that are there working on NASA contracts are almost all recruited from elsewhere, and most of them hate living there-- most leave the second their contract ends.

But contractors building missile parts have a big political influence, and apparently it was enough to get the previous administration to make pretty much the stupidest decision possible.

I like to extrapolate things into "Human lifetimes" to create interesting viewpoints

Assuming:

853 million travellers annually
72 year life expectancy
30 minutes to clear security on average

That works out to the TSA consuming the equivalent of 676 human lifetimes per year; about two entire human lifetimes every single day.

2,996 people dead in the 9/11 attack

14,876 human lifetimes wasted by TSA since 2001

> Both parties in this exchange were sloppy.

Orders in agriculture are typically made this way, and they do have the legal force of a binding contract, even though they are normally verbal agreements. Tech people discussing ag law are way over their skis.

This is an agricultural contract; most people here have zero experience in that area. Verbal contracts and orders in these types of circumstances are usually legally binding. You are right that this is not typcial of the contract law you are likely familiar with, but in agriculture this is a pretty obvious outcome. It probably wouldn't even be newsworthy if it weren't for the emoji slant.

Probably nobody will see this, but the fact that this is an agricultural contract is extremely relevant to this decision.

In agriculture there is a long history of using verbal contracts and a host of laws and legal precedent in place to support the use of such. It is not at all wise to extrapolate any decision made here onto normal contract law. I would consider this decision an expected outcome, and I believe the same conclusion would have been reached in the US system.

TBH it seems Question 4 is really more about how well you can read an SRS and implement whatever boneheaded thing it is saying as clearly as possible. It's a practical soft skills question for a programming career. Maybe news to some people, but most working developers are not actually sitting around doing greenfield architecture design all day long.

Even though it's an absolutely trivial question, I'm also not really surprised that it has such a high miss rate. Almost every professional career track has some kind of course where "shit gets real," and APCS has traditionally culled a lot of students that came into the class because they like video games or want to have a high paying career or something, but just can't wrap their heads around the material.

I therefore don't take this news as surprising, nor do I really think that it indicates any specific trouble with the APCS program. But I also think that APCS isn't designed to align with the goals of many people who take it. Most schools offer some basic 100-level computer literacy course and then a 400-level APCS and nothing in between.

I sort of agree with you, but as linux cant really do hard realtime, something like Zephyr needs to still exist. BOM costs and power consumption aren't the only reasons to choose an "embedded stack" over "linux."

Linux running as a management plane in a Zephyr process a la RTLinux might make some sense here.

I'm highly confident the Quest 3 and Apple MR Headset markets will not overlap that much.

I'm highly doubtful that the Apple headset will be anything other than a patent-staking product that will likely harm the vr/ar industry when it fails to gain traction because of Apple's closed minded approach to every. single. thing.

Alexa and DPReview are sad casualties that would likely have survived had they been bought by anyone but Amazon.

Also very sad to see the abrupt end of Amazon Smile. I was involved with an organization that happened to benefit reliably from the program, and this simply turns off the spigot on a quite reliable donation stream.

There are dozens of us!!!

Seriously though, it's everyone. Please kill shorts. Tap on one of those fuckers even accidentally and your feed is nothing but insta girl softcore shovelware for the next week. SMH

As a professional, I'd hope you would well understand the difference between building a 100G link with dedicated fiber and equipment that is widely available off-the-shelf, vs deploying 25GS-PON in its current state of development.

Google Fiber is not trying to compete with you; they essentially use the business as a testbed for consumer access and networking technologies at scale.

To be quite frank, you don't sound like you understand your business vertical all that well. Sounds typical of a small WISP lucky enough to have a couple of fat-pipe business customers paying the bills. Am I close?

What percentage of the warrants or subpoenas served by the FBI, Interpol and the UK's National Crime Agency are investigating Child Abuse? I certainly don't want to downlplay any serious crime, but none of these agencies are delivering their real argument. They are just hoping that an appeal to emotion will cause everybody not to notice the greater impact.

The systemic abuse of legal discovery over a great number of years by law enforcement has led to this in the first place. I am involved at my workplace in responding to these things, and it's a big pain in the ass. Courts are willing to grant very broad discovery rights; we have to push back on every request we get. If the records are old enough we can just delete them and be rid of the hassle, you bet we will. It's a huge cost savings to just be able to just say 'no' to a subpoena.
