(disclaimer: I work in a Climate and Energy R&D group)

I just want to jump in here because these numbers are all strange.

The author mixes units all over the place (e.g. MW vs MWh). The article confuses nameplate capacity and marginal cost. And there is no mention of capacity factor or dispatchability.

Very simply, the current state of the world:

- Renewable energy is getting more popular, and has zero marginal cost. That means they always sell to the grid, regardless of cost, and drive high variability in daily demand.

- Coal and nuclear have higher capital costs, and thus require 90%+ utilization to stay competative with natural gas. However, demand is low for a quarter the day now, so they are out. There is no saving coal, no matter how much political rhetorical goes into it, the economics do not work out.

- Renewables by themseles are not dispatchable. Do not confuse them with natural gas/coal/hydro/nuclear.

- Renewables+storage would be dispatchable (especially if you add HVDC to lower variability), and this gets us into the actual numbers from the article...

Lets do some math

Batteries currently cost about $150/kWh. That will continue to come down, but let's say we want to build a plant in the next 5 years, so maybe $100/kWh if we are really lucky.

For a 200MW dispatchable solar/wind plant, we'd have:

- ~25% capacity factor would be very optimistic (they aren't building in an ideal location in CO).

- That means 800MW of nameplate capacity to get an average of 200MW output.

- $1/W nameplate for solar these days => 800MW nameplate plant at $800M for just the solar.

- $100/kWh for batteries. Even if we only needed 24h of storage (though realistically you need more like 3 days), that means 200MW24h$150/kWh => $480M

=> Total plant cost is $1.28B, for 200MW of output, or $6400/kW.

Let's say we have

For 30 years, with a 5% rate of return on capital (3% over inflation), and a 1% O&M/y cost (this is really low, just to give it a fighting change, 3-6% is typical), that ends up as....

5.5 cents/kWh.

Which is way above natural gas (4 cents/kWh), so they'd never take it without federal subsidies.

Any bid below that isn't likely to be fully dispatchable, which makes it even less competative with natural gas, even if it is cheaper.

It's hard to compete with a low-capital cost power plant that has nearly free energy flowing out of a hole in the ground.
Who takes the other side of the trade? If someone is using a lot of USDT to buy Bitcoin, don't there have to be a lot of people who trade Bitcoin for USDT and then hold on to it?

On the other hand, seems like the Bitcoin price would rise due to people being skeptical about this newfangled Tether thing.
I've always thought it would be trivial for a very strong AI to own a city, it's factories, etc -- simply capture a nuke and hold all the people in a pleasant hostage situation. Pleasant because the AI will be a "benevolent dictator" for some time, bending the economy to build better things for itself, but without making conditions so bad that people revolt. In fact, AI of this sort would be amazingly good at administration duties, and society would probably be a lot better than it is now.

Perhaps even better would be if the AI rarely interceded in the human politics, and in fact worked to keep it's involvement and control totally secret.

Not necessarily according to Pinker's cherry picked statistics. Plantation owners were not going to achieve more by freeing their slaves, at least according to their own accounting.
No lie. After all nothing is stopping you from updating once every tuesday and rebooting after updates. You just wont have to do it 8 times in succession or stop in the middle of doing useful work to do so.

I just don't update nvidia or my kernel automatically and magically I only have to reboot less than once a month and always on my schedule.
Libertarian that originally wanted BTC to never touch the government hands here.

BTC has gotten insanely popular and the world has changed. Old people and finance institutions have gotten involved.

Now I'm okay with regulation on exchanges(I prefer no regulation, but I'm also reasonable).

You cant exactly regulate the blockchain, wallets will do transactions regardless. This would only affect exchanges.

There's a Weechat plugin [1], however I remember it having problems with UI lags. In addition, the official Freenode bridge on matrix.org often has problems as well, but that's what I get for not bothering to run my own bridge. At least it seems like the Weechat plugin is under active development. [2] I should give it another try.

Disclaimer: all of this is entirely unscientific, just observations.

From the perspective of a South African, we didn't have people walking into a public place (church, concert or otherwise) and shoot up a crowd. In general, undeveloped countries seem to have fewer problems with psychopaths (disregarding the ones in charge). I find this immensely curious.

One thing that Facebook has taught me is that problems are like biodiversity. It seems as though every time we solve a problem a previously minor problem becomes a major one. One example that many here should be familiar with is Facebook: it solved many quality-of-life problems, but in the process has allowed other unforeseen problems grow out of control. I seriously wonder whether rampant psychopathy (relationally speaking) is a symptom of development (technological, economic, social and otherwise). It's logically possible to see how: you no longer have to worry about where your next meal is coming from so, provided predisposition, you can start obsessively worrying about your fabricated issues.

Up until relatively recently, the entire human race was involved in a desperate struggle to survive. Now, while still a minority, a decent percentage of the human race no longer has to worry about where their next meal is coming from. These elite are typically concentrated in specific geographic regions, which is where I've noticed that most of these "novel problems" exist.

> BillG: The world is getting better, even if it doesn’t always feel that way.

I'll add to that: until our evolution reaches a point that we are no longer in a fight for survival (by ways of nature or science), we won't feel as though the world is getting better. We are incessant worriers by nature.

> church

The church kept us in line and now that it is being rejected, we are acting like rebellious children away from their overbearing parents for the first time - doing everything we weren't allowed to do. This will pass, and we'll have a slew of new problems to replace it.

Airgapping was my first instinct too, but the problem is we're dealing with state-level actors. Airgapping doesn't work with them. They're patient, well funded organizations. Trying to rely on never having a single type of car (any of which could have a hundred thousand copies on the road) hacked is a fools errand.

We need ways of disabling autonomous devices and detecting when they get hacked, not trying to win an impossibly hard game.
Actualy the reason the Germans didnt use nerve gas in WW2 was because they mistakenly assumed Britain and Russia also already had them. Hitler was otherwise pretty keen on them.
Still better than no comment.

It is getting better for some people by some measures, and worse for others by other measures. What Pinker and Gates are attempting to impose is a tyranny of faux rationality--"an 800 pg book with sources up the wazoo say that the world is getting better, all these whiny poor folk must just be delusional".
If you interpret "the UN" in this context as "the 5 permanent members of the UN Security Council", it's pretty much the same thing as you're saying.

To me it's merely amusing. Sometimes things get to the front page on the virtue of just being a little different and amusing.
Of course it's not possible to always be your own target audience, just an ideal example. Yet your counterexample is also interesting. I'd say that you need the best domain expert to design something for someone who doesn't care how tech works. Obviously, this expert canNOT be one of those myopic tech-centered geeks, but the essence of designing for non-tech users is to understand the tasks & goals at a very deep level so that you can effectively simplify the UI & process.

I'm all over architecture, as that can really simplify the dev, maint, upgrade, sysadmin, & running processes.

But it'll take a lot more than these examples to convince me that personas are useful for development.

I could be convinced that Personas are useful for marketing, but that's because I don't know that much about marketing ;-)
Patent agents - the term for a non-lawyer who passes the patent bar exam and gets a USPTO registration - are qualified to directly file for patents, and tend to be used by law firms for other analytical tasks requiring technical expertise. However, they tend not to be involved in trademark work, nor copyright work, for a variety of reasons.
UEFI is a heavy-weight solution in comparison as well. You can compile some pretty small Linux kernels.
Take a deep breath. Everything is alright and you have a bright future ahead. Getting fired is same as you leaving the job, without having a offer in hand, discarding any emotional turbulence. Keep applying for jobs and very soon you'll get a job, you always desired for. I hope you have enough cash to keep you covered, spend money with prudence. And smile, things are gonna be great for you, very soon.
>If Tether is not legitimate, wouldn't Tether holders sell their Tether for BTC and other crypto assets which would increase the prices of crypto assets?

It would increase the price of BTC in tether. But the tether to dollar peg would fail. All the BTC stored in tether based exchanges would move to fiat based exhanges. If people decide to hold onto BTC because it is safer, it might cause a price increase for a short time.

But people who held tether, would likely be interested in selling BTC for real cash. The whole point of tether was to avoid the price instability of other coins.

Plus, if tether really has printed a billion dollars or more of fake dollars, the disappearnce of that will cause the price to drop over the long term.

And don't discount pure panic.

Market cap is a stupid measurement for currencies. Two billion of fake money could distort the "market cap" by hundreds of billions.

You also have to wonder if shady exchanges just decide they are better off stealing all the coins now. Because without tether, a lot of them won't survive.
If anyone cares to, I’m curious about this and it would be great to benefit from your insight. I haven’t had anything to do with autonomous systems, but from my layman perspective it seems as though there would be legitimate benefits to inter-vehicle communication assuming a sufficiently sophisticated network / platform—

For example, cars being able to broadcast their immediate path and do some dynamic route mapping based on which lanes and areas will be in use by the time it arrives; being able to agree with nearby vehicles about routes that are partially colocated so they could join together bumper to bumper for that leg and realize fuel efficiencies (I have no idea if that would actually be useful but I’m brainstorming possibilities); being able to negotiate a car parking space in advance of arrival...

Is it that there actually aren’t many applications where inter-car communication is useful, or is it more that the benefits of communications like these are outweighed by risks to security, or am I missing important pieces of the puzzle?
I went the other direction. My advice would be to make pretty certain you know you'll like whichever area of law you want to go into.

I thought I would like corporate law especially working with startups. I got a job doing pretty much exactly what I wanted to do, but I didn't actually like it and only practiced for a year.

In my limited, purely anecdotal experience, comparing my developer friends and my lawyer friends, a much larger percentage of my lawyer friends hate their jobs.
I always wondered why this didn't happen in every area with coal. I get many of these areas are not the best for solar or wind but if you provide a way for these people to transition to something different you're far more likely to win their support versus the narrative that ran rampant in the election where no one cared about the coal miners.

Counterpoints: AI is easy to fool, you think people write completely true statements in all their twitter messages? Most of it is just spam. And do you honestly think that we are going to let 1000s of self driving cars drive around by themselves without some sort of checkpoint system in place, remote stop, inability to drive off the road etc? As for figuring out the leaders of the future, what do you think the whole education system is already doing??

And defence is possible, it just takes due diligence. Or in this fantasy future of yours, an AI that probes your business for you 247 and fixes security holes it finds.

Honestly, I expect doom and gloom AI posts in the media, not on HN where people are expected to have some notion of an IQ.
I read somewhere that people have developed POCs of these using JavaScript. At minimum, you'll want to keep your browser up to date as there are mitigations happening there too. Who knew that exposing high precision timers to untrusted JavaScript would be a bad idea?

Apart from browsers, it's fortunately pretty easy to avoid running code you don't trust on your devices.

There's a very simple update mechanism for any car (or anything that doesn't get put in space or dropped to the bottom of the ocean, really). Recalls.

They're expensive, annoying, etc. But they're safe (or safer, at least), and if you screw up badly enough that a safety-critical system needs an update, they're necessary.

I don't think anyone is arguing that the infotainment system should be disconnected from the world, but the core driving systems (steering, brakes, transmission, etc) should be air-gapped and inaccessible without physical access to the interior of the car. Also, that access could (and maybe should) be disabled when the car's engine is running, preventing an attacker from plugging in a wireless device and then subverting the system with the car in motion.
No, Tether fired the auditor because they were trying to actually do work.

> Given the excruciatingly detailed procedures Friedman was undertaking for the relatively simple balance sheet of tether, it became clear that an audit would be unattainable in a reasonable time frame.
Same here. Yeah, it points to rather poor handling of error condition in this case, and it is an example of deeper problem of terrible error handling in Go, but overall - I don't see what the point is. There's plenty of worse code all over the place, in many programs, written in many languages, and this is hardly a notable offender.
If you employ even a fairly simple AI to monitor, evaluate and score the party members for their actions you would kind of have a state run by AI. Of course this AI would not be "aware" of itself, but I think it is an interesting example how we might end up being "enslaved" without even noticing.

Hey there! Status is acctually making this investment not in the traditional capacity, but rather allowing New Vector (matrix, riot) to continue their development on their own terms.

Status has a very close to working MVP; developing an application completely based off of new protocols and a decentralized environment is no easy task and much R&D still has to be done with Ethereum and the whole ecosystem in general before any of these new systems are production ready; and Status aims to stay true to the ethos of keeping a completely decentralized interface and system while supporting others in the ecosystem that share that same vision.

If you sign up for our alpha on status.im you can test out our (already functional) product. The majority of work left to be done is in performance and security audits.
How is this different from Gong.io? I'm desperately looking for a better solution.
I'm not seeing the administrators do anything of the sort - responding to the guy above me suggesting that these courses could be a factor in a potential glut of professionals in the field.

I am definitely being harsh in my analysis - however, try to picture the average software developer or student attempting to learn this. I'm seeing a lecture on deep generative models. Crack open the deep learning bible and crack open to that chapter - reading through that and understanding everything will realistically be way beyond the ability of most of the people attempting the course. If I were hiring someone to use RBM's or an autoencoder or something like that, I'd want to be positive they have a strong understanding of them - in the same way you might ask a software dev in an interview some stupid bubblesort question to ensure he didn't copy his friends code to get his degree.
You’re absolutely right. For anyone who wants to test this, try searching for “State Farm” in Reddit and you’ll see the results almost never have anything to do with whether Statefarm actually pays claims, is fair priced, or a good value to the customer. The posts are all from their internal marketing department doing shit like posting a false AMA request for Jake from State Farm as some kind of low-quality joke to shy away from the points that actually matter.

The current way an x86 platform is booted to linux today uses mostly closed source UEFI DXE drivers, so the current boot flow is really (simplified) like this:

UEFI DXE loads disk/network -> Linux

We're doing
Linux (with commonly used open source drivers)-> Linux

It's possible that if your end goal is a Linux system without too many requirements, you could stop at the first Linux system without ever booting the second. However the bios rom memory is pretty small, and we're mostly working with about 4-8mb of free space left not including the ME region or UEFI PEI.
I've already upgraded some of my extensions to the tagged template literal syntax. It's so much nicer than what I was working with before, and is tiding me over for IE11 support in lit-html. Pretty big wins all around. Next, I'm gonna have to take a deeper look at those TS decorators!

Firmware with a built in web server is pretty spooky. Why do they have that?
Chances are you don't want to re-flash your firmware on your servers just to change what kernel you run in production. The kernel in flash also has space constraints that will make it a pretty small kernel with a lot of features turned off.
Unpopular opinion ahead. Having worked in the security industry for a few thousand years (computer years), I can say I would never own a car that can talk to the internet. I plan to move far away from cities very soon for this and several other reasons. People will argue about this and meanwhile the "impossible" will happen, repeatedly. I just replaced the engine and transmission in my non internet vehicle and hope to get another 500k miles.
