Have you heard of Tesla's batter in south Australia? It was recently expanded to 193 MWh. Care to guess how long it'll run at full power? Around 60-100 minutes. At its rated power of 100 MW, it can power around 25% of South Australia's lowest demand. That's it. At peak demand, the fraction is lower still.

Cars have a fraction of the energy storage capacity of a single battery site and not all cars are connected to the grid at all times and neither will all their stored energy be usable.

Batteries aren't the silver bullet many imaging them to be. The real solution is expanding transmission capacity, building more renewables and supplementing that by nuclear or hydro.
Software developers do not have obligations aside from do the minimum dictated by your boss to not be terminated, so I suspect the concept of obligations is foreign to most software developers.

In most other professions there exists licensing and such licensing establishes rules of conduct. Violation of such results not just in termination of a job but failure to practice, usually forever. In those professions obligations are essentially laws, except violating such may not, but can, result in incarceration. Instead they will just be poor and forever unemployable in their invested trade.
Cool. One trap worker-owned companies often fall into is to neglect investing into risky/long-term projects and as a result fall behind the industry. When the choice is 2x salary for 3 years or some R&D investment one does not fully grasp, many individual members choose the former.

I never understood why Uber doesn’t allow drivers to set their own price.
There hasn't been nearly enough done on demand shaping.

Rather than wondering how we can store all the excess capacity it's probably more cost effective to wonder how we can shift demand.

Aluminum smelters in Germany use gargantuan amounts of electricity, for instance, but they can use 3x as much on Friday when power is cheap than Monday when it's not with relative ease.

Using a powerwall to keep production steady would be a ridiculous waste of money.

Storage heaters need to make a comeback, as well.
That's not ideal, as it would eat through the battery's cycle life at a much quicker rate.
> Specifically, in England and Wales there's usually no record of the exact boundary between two properties

I think that the logical explanation for this is that it just isn't important enough to record the exact boundary between two properties.

In the US, most of the land was (dubiously) obtained by the government from the natives, divided into large tracts, sold to land speculators who then divided it into smaller tracts, who then sold it to individuals and families far, far away from the land. The owner then had to go find it. This system pretty much required exact boundaries be known from the start.

In the modern US, most land boundaries aren't super important anymore. Want to build a shed in your backyard? Your local zoning rules probably say it has to be 10-15 feet away from the property boundary. If you build it 10-15 feet away from what you think is the property boundary, nobody is going to send in the surveyors to make sure and then tell you to move your shed 1.5 feet to the left.

The situations in the US where the exact boundaries are needed are probably the same situations where the exact boundaries are needed in the UK.
That's a pay per view event waiting to happen.
I'd also like to add that the whole notion of there existing "telltale signs" and fingerprinting to discern between good-guy Western governments and bad-guy Ze Russianz!11! is total BS. Unless Google is in the loop, it's completely unreasonable to expect them to know who is who -- and no, it's not reasonable to expect them to ask before they act.
"Though I suspect another problem would be getting another ship large enough for all those cranes and strong enough to support all the weight close enough to the ship without them damaging each other by knocking into each other from waves and weight movement."

I don't thinks this is your concern. Desperate times, desperate measures. Likely you would fix/attach the crane ship to the container ship. I am sure they are willing to salvage two ships at this time. The daily losses must be gigantic.
Your requirements for "proper monitoring" are not everyones requirements.

On a current gig, we host at heroku. Our monitoring is all about 95th percentile response-times, secondary services, backlogs, slow-queries and whatnots. For another job, "disk space filling up" is important. Again another job will need to monitor email-delivery-rates and so on and so forth.
It often means that your manager is doing nothing but the administration around management, and your team leads are pseudo-managers.

There are three forms of management: The team lead as manager, the manager that has 2-4 teams and is responsible for communication flow in the system, and the pure administrative manager overseeing a community of developers that are self-managing.

I hate the pure administrative manager model.

Is paying tens of thousands of dollars for the car, and the software loaded on it, not enough of a barrier?
Start outside-in, then decompose to unit tests over time.

Most code bases interface with something with a relatively stable/published interface. Like a database or network library.

If you can find these points, you can mock where you interact with the outside world, then test the entire code base end to end. Over time you can refactor the insides to be more decomposed and testable.

As an example, a code base I worked on involved interacting with network firmware, then sending events to a UI for display. It also received these commands from the UI and told the firmware to do certain things. With some work, we could mock the source and sink of these APIs and inject them as dependencies (instead of instantiating directly). This let us test our huge ball of code to see if it did what was expected. Did the code send the right message to firmware when it got certain UI commands? Did it get in a good or bad state when the firmware responded incorrectly?

This took a bit of work to mock and isolate how our code talked to these interfaces, but once in place, it was a game changer. We could pretty easily isolate problems in our codebase and recreate issues in a testable way.

Then we would take the next step and decompose further, usually on a case by case basis, depending on the cost/benefit of refactoring. But it’s not realistic you’ll get to everything being decomposed in a legacy system.

But what if it has the next stock of PS5s? It’s all fun and games until same-delivery is put in jeopardy.

And to think, some people wanted to jettison said possible stock out into the desert. Yes the boat is stuck, but I need to know what’s on it before we do anything crazy. There’s a heroine cartel going nuts right now somewhere.

It’s time we move on to the next question: What’s on the boat?
I've seen this suggested often but I don't think I've ever seen any information about how it'd actually work in practise. Do the car companies actually want to do it, how is the car owner compensated for the battery wear and tear and who'd be in control of the management (government regulators, energy companies, car manufacturers).

Are there any examples of pilot schemes that have used cars in this way?

This is far more common than you think. ISPs, hotels, cafes, mobile providers do this en masse far more than you think. Have you forgotten the NSA “SSL added and removed here”? That was a highly targeted attack against infrastructure. What we’re discussing here is 10x easier to achieve.

> And even if it was the risk is just crap injected into someone’s blog.

That “crap injected” has full control over the DOM, any authentication, and everything displayed. How many of your users would happily put their creds into a fake login modal that popped up claiming to be SSO for a popular identity provider?
oh I've heard about that one too actually - don't they suspend a large weight and use its potential energy as storage?

Yeah.

US also benefitted from being isolated from any threats by huge bodies of water, having a ton of cheap land, speaking english and being welcoming to immigrants. Thanks to this the whole global economy is tied to the dollar and runs through wall street.

Yes, the point with selling electricity is that you need to guarantee that you will deliver some fixed amount of electricity. If you depend on wind power plants how this guarantee can be given? What if wind stops.

Maybe it would make sense to build huge bitcoin mining data centers and mine bitcoins in case of surplus. Hardly useful, but given current coins rush could be profitable. Better than paying producers for not producing energy.

Obeying the law is not naivety. Protecting your customers is not naivety. Pass legislation through both houses of the US enforcing such privileged "Government Right to Hack" first before claiming any morality. Of-course that will likely lead to economic collapse as no-one (allies or enemies) will trust US software or services.
Google, Facebook, and Twitter see themselves as nation-states now, it's becoming clear. It's time to knock these guys down a few notches. China doesn't have fickle, smug, spoiled, naive zealots working on their offensive and defensive cyber efforts -- but man, we sure do. I think the CCP has already beaten us. Sad that an adtech company like Google is involved at all in national defense.
I really admire these kind of experiments, and hopefully it'll work out for them.

However it seems that people vastly underestimate how hard it is to run a business like Uber. You have to take care of handling a complex demand/supply ratio, geolocation, fraud management, a seamless payment system, tax rates, etc. etc.

Hopefully these initiatives will produce meaningful value locally all around the world, contributing to a more decentralized Internet.
Looks like your right. The US has:
https://en.wikipedia.org/wiki/Sikorsky_CH-53E_Super_Stallion... as its near equivalent with a external payload of 36,000 lb. The Russian helicopter carries 8000lbs more at 44,000lb, though Wikipedia doesn't say if this is an external or internal payload.

Looks like a 40ft shipping container weights around 8000lbs empty, couldn't find a stat on full. It seems such an operation would be outside the capacity of these helicopters. Sure they could comfortably lift empty containers, but probably not full ones.
And, of course, trust is having a crisis. Witness the Bitcoin crowd, and their distrust of the FED and other political institutions.
Only for so long. Their stock price will suffer at a certain point. Not to mention the bad PR that come with it. The more of these that we see globally the harder it would be for them to run at a loss. As a CO-OP they can take growth slowly. They don't have the same investor pressure
The exact same logic applies to nuclear weapons. How many lives have they saved by being a credible deterrent over the decades? Every country should be allowed to possess them, or else none should. I'm not even sure if the latter is desirable (it'll lead to millions of deaths in conventional warfare), but it doesn't matter, since it is completely impossible (the tech exists, so it will be used, invariably). We're left with only one logical option.

You can either be lucky by birth or circumstances, or you can learn more and more about your own being, how you came to be where you are, and what things truly are of interest to you. That’s the special sauce that I think a lot of people downplay and what gives the wealthy (in both time and money) advantages often, in my experience.

> I recently looked on US property websites and was surprised that the map showed the exact edge of the property as well as every other property around it

The US does not have land registration. So, while it's nice that you got a web site with a map, that's worth almost nothing in court.

In contrast the small fee to the Land Registry buys you paperwork that a court of law is compelled to accept as the last word on who owns that land.

In the US if you're absolutely sure you own your plot, but alas somebody else has paperwork which they say proves they own it, you're looking at an expensive court case to find out who is right.

Which is of course why the US doesn't have a land registry, the lawyers and insurers lobby to ensure they get to keep charging people for the peace of mind that they're not going to wake up to find somebody else owns their home.
Because nobody in government has any incentive to do something that risks shrinking the size of the pie.
Serious question, why not simply stop generating energy by wind istead of stopping nuclear stallar ?

You „can” stop generating power using wind.

Get up to 30% from nuclear and rest from automated wind farms.
That's what I said though. There is 5GW of HVDC import/export capacity to Europe. By 2025 maybe 10GW. These places are likely to be windy when we are windy, so they won't want the power.
What I really want to know is the story behind how these emoji's came to be?! Who was tasked to come up with this sticker list of symbols? What was the decision/strategy behind the selection of these symbols? etc etc. it seems soooo arbitrary at first-glance.

> A good chunk of it sounds _a lot_ like the UNIX philosophy

Yes, it does _sound_ this way, doesn't it?

That's because the UNIX philosophy is misrepresented. Having small self contained pieces of code serves you nothing if they can't be called on many different tasks with different arguments.

In theory, you could make generic microservices that behave like UNIX tools. On practice if you try that, your CRUD application will reside 90% in a single service, and you'll have some extra tools for a few more complex parts. (What isn't a bad architecture, by the way, but it's not what people describe as "microservices".)
Do you think the Chinese Communist Government is morally equivalent to the US government?
My M1 Air results are similar to yours.
The US wouldn't hesitate to come after and make an example of individual developers or small companies.

But Google? Our intelligence agencies are already relatively unpopular (if you can trust the polls) [1]. I'm not sure that the US government could attack Google like that without serious consequences from the public.

Only playing defense won't work for nation states due to similar thought processes of mutually assured destruction. If you're enemy has a bigger and scarier gun, it puts you at a disadvantage in geo politics.

Also, I'm not sure the clear line is that clear. There will almost always be a tipping point for people for this type of scenario. If the hacking operation that was exposed would have prevented an attack that kills 1 person, was it still OK to expose? 100 people? 10,000? It's almost impossible to know what the exposure cost will be but if people die due to it and it becomes known, some people will rethink what the "right" thing to do was.

This type of stuff seems like it should be decided by elected representatives and not by some team of coders that work for some for profit company. It seems possible to me that the decision they made was based purely on what was best for Google.

I think we as tech workers need to acknowledge and understand the viewpoints contrary to ours and try to compromise with those on the other side. This type of issue is complex and I think we really need to acknowledge that there is no easy "right" solution to something like this. Blind idealism on both sides of the issue won't be good for either side or for society in general. We as tech workers are not infallible and we don't deserve to dictate rules to society just because we know how to write code.

Well, at one time, cash registers, packaged food, and stores were all technological innovations.

> It seems very dangerous to contribute to open source these days if you are not in the right Twitter cliques.

Nope. Lots of people contribute to Open Source without being in any Twitter cliques, they're just getting on with the work and doing their best.

One could also flip what you wrote, on its head and say "It seems very difficult to be visible in open source these days if you have been doing things that are illegal or frowned upon". It's the same thing, just without the persecution complex.
I agree that what you describe would be termed the "happy path" of goal setting. It's important to recognize the edge cases though:

- First off the whole setup only really works if the employee has goals that are approximately aligned with the company. Someone who dreams of maximum money for minimum effort will need "creative" managing to make it work for both the employee and the company. (Maybe something in automation though?) Employees whose life goals reside outside the default company promotion track cannot really be motivated with "career growth" and often the manager has no means to accommodate growth in the desired direction.

- Both manager, employee and company need to be in a position to actually provide. The easiest example is probably promotions: if a manager has only one senior position available and multiple candidates available, some candidates will be disappointed. If that happens often enough, the system falls apart since any promises of "career growth if you meet these goals" will no longer be trusted.

At least in the northeast, it's common in the US OTR trucking industry to register the trailers in Maine. Registration fees in Maine are significantly less than in neighboring states. You'll also see a lot of recreational trailers (boats, RVs) registered in Maine.
This is impressive. The nerd in me wants to play with it right away, but the skeptic me just doesn't see that this will be mass produced anytime soon. Hopefully I'm wrong.
Hardly surprising. Say what you will about the person elected to the office of POTUS but if their dominant attitude is "America First" then it shouldn't be a surprise if policies -- and the result of policies -- actually put America first or at the head of the line. I'm curious how Israel out-did us though. I have to imagine their massive brain trust of medical and biotech has something to do with it.
It kinda reads like the thing explainer, a book by the person who draws stick people and thinking machines, which only uses the ten hundred most common words.
So, bigotry is bad, but calling it out with strong words, such as “repugnant”, is even worse?
It isn't the silver bullet some people say it is. Firstly, as others mentioned it really hammers the battery life. Secondly, it requires cars not being full so they can be topped up, which means less range.

Not to mention I don't think the local grid to houses can support loads of cars suddenly getting charged at once, which is what you want for big wind spikes.
It was in jest of course. The repetition just felt a bit robotic.
There are other useful things you could do with excess energy and seawater. Either a desalination plant or a hydrogen plant. If the energy price is 0 those could operate economically.

True,

But large companies tend to have MBA types scurrying around rooting this stuff out as it pops up or shortly thereafter. Government has no such sort of immune system to fix these problems on the go. It just gets sicker and sicker until the tax payers vote for something drastic or revolt.

You see this in nonprofit entities too. They get big, abstract away from their mission and waste a lot of money until someone gets tasked with cleaning house or a more mission-driven comes along and replaces them.
It sure does seem written by GPT3, but at the same time, it makes a remarkable amount of sense!
My manager got the message after I copied my personal growth and goals 3 years in a row from the previous self-review.

In my late forties, I know what I can do and I’m very good at it. I know what I can’t do well, and I avoid it and tell them to make sure things don’t go bad. (Mostly anything related to managing other people.)

I will learn new technical things on an as-needed basis if there’s a project that requires it, or if it tickles my personal interests. They know that, it won’t change.

I don’t need personal career growth plans. I have no interest in being anything more than a principal engineer. I don’t need goals. Give me a complex technical task and it will get done.

It’s been 8 years now since I rejected to fill in a self-review, and things couldn’t have been better.

Every year, I get a nice bonus, a boat load of RSUs, and an above average salary increase. They seem to be happy with my work.

I hope you as a manager would respect a goal of “I want things to stay the way they are, and that’s the end of it.”
Historic politicians spoiled it as well. Modern ones are by no means short of company.
IMO recycling batteries after use in cars is a more interesting idea. A 20% reduction in a cars range is significant but not an issue in actual power storage.
