Suppose we want to get rid of all carbon sources, and minimize the amount of energy storage required due to the high cost.

Is it possible to minimize storage with nuclear? Yes, in theory, you spec the fixed generation amount for the peak demand and then have excess supply the rest of the time. Inefficient, but it works. This is clearly not the optimal mix however.

Is it possible to minimize storage with solar? No. It doesn't generate at night, that requires an enormous amount of energy storage to overcome, pure solar is a fail.

Is it possible to minimize storage with wind? Yes, but you have to match the peak demand with the minimum wind output. That's going to explode costs even worse than pure nuclear. Combining wind with storage to smooth out the load might be better, but by the time that's cost effective, so would using a smaller amount of storage to smooth the day/night load for nuclear and reduce the amount of generating capacity you need there too. Also, wind is not the cheapest generating technology to begin with (solar is cheaper).

So what happens if we combine them?

Solar plus wind is better, but still problematic. Wind generates at night, except when it doesn't. On a still night you could have to survive the whole night almost entirely on stored energy, but if you need almost as much storage capacity as for pure solar then you might as well make use of it every night and take advantage of the cheaper generation from solar than wind.

Wind + nuclear doesn't seem especially interesting either. The problem with wind in general is that its output varies randomly and doesn't track demand whatsoever, so you end up needing a large amount of storage proportional to the amount of wind generation you have. And wind isn't that cheap and storage is really expensive.

But solar + nuclear is excellent. The demand for electricity is higher during the day, which is when solar generates. Solar doesn't generate at night, but nuclear does. So you spec enough nuclear generation for the minimum nighttime load and use solar to both handle the higher daytime load and charge up the much smaller amount of energy storage you need to handle just the baseload-to-peak load differential in the few hours between when solar stops generating and people go to sleep, instead of the whole demand for the whole night.

You can also then price electricity higher during the night, which makes perfect sense when the solar that generates only during the day is the cheapest generation technology, and then nuclear pays for itself by beating solar+storage on cost for twelve hours a day while allowing you to cut your required solar generating capacity more than in half for the other twelve hours.
My guess is that data science roles will merge with business analyst roles. Python and r will slowly join excel as tools of choice for making tables and charts to stick in powerpoint slides and pdf reports. Meanwhile the machine learning side of things will be the domain of _something_ engineers with candidates more likely to come from the computer science/math/engineer world rather than the sciences. (Other then those with degrees in physic who seem able to perpetually land wherever they feel like.)

Yeah no, when's the last time you've actually seen the rules enforced?
>During the times when those rates were in effect there were so many deductions that nobody with an accountant actually paid them.

Quite a lot of people with accountants paid the highest tax bracket rates during the Clinton era, and the ~70% rates prior to the Reagan era.

>It wasn't just that business expenses were deductions, people were deducting their homes and personal vehicles and everything.

I agree the system is gamed to favor things wealthy people perceive as good for them, and have been successful at convincing enough of the political participants that it's good for the country generally.

We're unlikely to see a federal reserve policy change. It's becoming increasingly clear the relationship between the stock market and interest rates, and the economy and possibly the politics will not accept an increase in rates. Even the most recent attempt at doing so caused an immediate backlash, even if it's good policy. If there's a recession, how do we combat it by lowering already low interest rates?

Solving the political problem first also has difficulties. How do we get a more representative political class, when it functions on money as if politics is a product that you can buy? Establish only living persons can contribute a thing of value to a campaign, and perhaps even only citizens can do so? That would take a constitutional amendment, as the Court has ruled that corporations have free speech rights and money is free speech.

Instead of borrowing $2 trillion in cheap loans in exchange for infrastructure assets, the political class chose to borrow $2 trillion for tax cuts primarily for the wealthy. So it isn't just poor people going into debt to buy things.

De-feudalizing this system by either politics or law is going to be very difficult. And that leaves something economically breaking in order to compel some kind of political change, whether non-violent or otherwise.
Because intel strictly forbids publishing benchmarks of their processors with the "hardware vulnerability mitigations" applied. Even OEMs cannot show them to their enterprise customers. You can do your own benchmarking after buying the systems. So, no money, no real-world benchmarking.
Point taken that the U.S./Canada stats likely skew to more recent versions. However, I'm in the U.S. and several of my devices couldn't possibly even download his company's app. Granted, I'm an outlier and tend to use my devices until they die. (they are actually still pretty useful around-the-house devices and can browse the web, watch videos, play some older games etc. Maybe I'll fire up a couple of them and open the Play app just to nudge the stats by a few millionths of a percent. ;-)
I can't speak for the person you're responding to, but

> Are you saying we don't have the materials to do it?

Yes. At least without substantially expanding mining operations.

> Or we don't have the factory capacity for it?

We're NOWHERE near that kind of production level.

> The biggest flaw with this model is what happens on cloudy, still weeks? I guess some kind of waste to energy, wood, and bio gas, hydrogen power station would be less expensive than a nuclear reactor.

Not if we price in carbon emissions.

I also have to mention that there are plenty of places that people live where it is almost always cloudy and almost never windy (at the same time). I will keep saying this: we need diversified energy portfolios. The key though, is we don't want any of those sources producing emissions, or to at least minimize them as much as possible (we're playing a negative sum game here)
>> We’re going to pass but will be cheering for you from the sidelines. (@comaddox)

> This is just a ridiculous phrase and pet peeve of mine. What is this?

Don’t look a gift horse in the mouth! When a VC says “we’re going to pass”, that is a godsend - it’s a straight no. It saves so much time, and they aren’t screwing with you trying to move the goal posts or ask for more traction or a lead or anything else. They’re doing you a huge favor by saying no.

They only tacked on the “cheering you on from the sidelines” to be nice. What’s wrong with being nice? Chances are quite high that they truly would love to see you succeed, they just don’t want to give you their money, and there are a hundred and one reasons they might not want to give you money, most of which aren’t any kind of judgement or insult on you.
I made a (paid, freemium) program (for Windows) called Tankan for memorizing kanji that is very efficient. Much more so than spaced repetition.

http://www.kylheku.com/tankan/

In Tankan, instead of viewing flashcards, you take batch tests, typing answers into blanks, tabbing from one field to the next. The machine grades your answers as a batch, and you can take a new test immediately over just the unanswered/incorrect items.

As you gain proficiency, a "pipeline" process takes over: your eyes can read ahead two or three kanji while your fingers basically don't stop.

I've been able to review some 1200 characters in the space of about 40 minutes of furious typing, when my accuracy on those characters hit around 96%.

Instead of spaced repetition, once you're proficient, you can just fire this up once every few months, and just review every kanji you know in one short, sweet little session and be done with it.
'Major' is up to personal definition and will distract people here no doubt. Metafiter has been my long-time lighthouse for this kind of gauge, though obviously not as big as its peak.

- Anyone can view the site and its content

- Very clearly putting their rules of the road up (link above) before you can 'join'

- Commenting/posting/membership is a $5, one time fee

- A one-week wait before you can post

- Paid moderation

And it works.
"Major". Hacker news is a small, heavily user-policed special interest site.
This post is more reasonable for smaller curated communities, but as we can see from, well, every large social website that exists currently, it can be difficult to scale. I'm curious what the other thinks the solution would be to an obvious example like Twitter. When a website consists of so many groups of users that everyone's definition of 'assholes' contradicts the others, you find that banning them gets to be pretty difficult, not to mention the amount of humans that are required to moderate.

edit: Even if you have a policy that seems perfect to you, it will not be executed perfectly in practice when there are 1,000 different people attempting to enforce it as moderators.

It is your fault, but, nevertheless I disagree that it is bad to not do stuff about it (although of course you can do it anyways if you want to). I prefer not to have such stuff; I allow any except that I do not have unlimited bandwidth ahd disk space, so there is that consideration only. Clients can use kill files and other filters (if accessing them by NNTP) to avoid messages they do not like. Messages can also be copied on other servers, which may have different policies; I do not policy your server that copies the messages, but only not to overly flood the bandwidth. My software, called "sqlnetnews", deliberately does not support control messages (you can still post messages with a "Supersedes" header, since it can still be useful sometimes, but it won't result in the old version deleted; it does, however, reject any messages with a "Approved" header). Maybe you hate me for it, but Dave Hayes has "Freedom Knights" and it is like that (but in my case, for Unusenet rather than Usenet). While cancels can be posted (as long as the "Approved" header is omitted), they are not processed. I will not force anyone to use these services and will not disallow others from making echo services (a feature of Unusenet, designed to enforce that you have freedom globally even if not locally (local policies are up to the server administrator, not me)).

Not always. CPUs have extensive "machine check" capabilities. some of these MCE events are recoverable, some not.

If the processor fires an unrecoverable MCE event, you're frozen with a nice, explanatory panic.
Often. Perhaps not as immediate and often as I'd might like, but often enough.

Are you sure you only pay if you lose?

>EU ≠ USA

I don't see why this changes anything. Lawyers still cost a lot of money. They might not seem like they cost a lot of money to Americans, but that's because Americans earn a lot more money.

>So what? If you have a grievance with an entity, that's the entity you have to fight a lawsuit against.

One of the grievances people have against GDPR is that they don't like how GDPR's enforcement depends so much on the individual person at DPAs. You'll still have to deal with the person afterwards that you sued.
HN moderators are actually pretty active, but usually maintain a low profile compared to how things appear on other websites, so it can be harder to notice the work that they do.
I got the idea from reading about colonoscopy practices in Europe, for example only 6% of people in Finland underwent sedation during a colonoscopy [0].

I have to go for a colonoscopy in another two and a half years, and I’ll insist on no sedation that time as well. You seem familiar with the process, is there a way to avoid feeling like I’m having a fight with the staff next time?

A lot of it was. Like VR, blockchain. Companies didn't know whether they needed this new tool. A lot of them didn't. Like VR, the long tail on this might be huge. It will just be new technologies that weren't possible before, not huge improvements on existing ones like some companies thought.

I'm a little confused by the implications the article is making. Density in the outer suburbs is probably not a good idea, for all the reasons the article mentions, such as traffic. Then you have to factor in all the other things like electricity, water, sewage, garbage collection, police, firefighters, more public schooling, etc.

I'm 100% all for more density, but just throwing up 8 story apartments in what were single-family lots all over the outer suburbs isn't really going to help anyone.

There are all kinds of competing forces at play, but the one I think is the hardest to understand is quality of life. Everyone has an idea of what works for them and it's different for everyone. Some of us do want to live in the core of a city and be as close to the energy as possible. While some of us need to be in a quiet area far from it all. I don't want to shame people for wanting to live in a single-family home with room for a garden and toolshed. Those spaces should exist and be in reach for anyone who wants that lifestyle.

Yet, I do think we need to rethink what is considered the "core" of a city and should expect and demand that those areas build up. That's when I start getting frustrated with cities on the peninsula. All of the downtowns from Burlingame to Cupertino have height limits of 2 stories. Are you kidding me? None of them have views, and all of them have Caltrain stops.

So I don't think "liberal America" is necessarily wrong, and I'm not sure the article is convincing me of that.
I'm not sure why the GP said his iPhone 4 won't upgrade past iOS 5, but it's worth noting: while an iPhone 4 can be upgraded to iOS 7, actually doing so is a bad idea unless you want your phone to run slow as molasses. You'll be much better off on iOS 6 or 5.

(I suppose there may be a security argument for upgrading as far as possible, but it's not like iOS 7 is up-to-date either. If you're concerned about security, you shouldn't be using an iPhone 4.)
Nice, at a glance this is pretty well-detailed. Bookmarked. Wait, I've been hacked!

This is not what Google uses, but shares many similarities, so the title of "Google's" isn't fully correct.

This is an example from https://rework.withgoogle.com/guides/
>It sounds like you're rolling with whatever Google's latest 'solution' to fragmentation

> You say that O/P/Q are 88% of your devices but they only represent 38.7% of devices accessing the market

NO !!

That's the issue with these articles. They just read the android dashboard and pretend that:

- it applies everywhere

- many different devices = difficulty for the devs or users

The dashboard reports the global figures. These figures are heavily skewed by third world countries where old versions of Android are still shipping.

"The market" ... this is absolutely meaningless. If you work for let's say Lyft, the market is wherever lyft can operate, that's not the whole world, so whatever the Android version dashboard tells is meaningless for you or your users.

For our market 88% of the users are O or superior. 6 months ago we stopped supporting devices older than lollipop for this particular app (IIRC it was because they don't support TLS 1.3 and it was giving us some security concerns). For the app I worked on before, we had legacy apks : apks that are still distributed on the play store but that we don't maintain. Basically when we decided to stop "supporting" an old Android version. And by old; I mean Android Eclair; this was a pretty popular app with tons of users on various devices. So we take our current app that still support that old API level. We make sure that it is as stable as we can get it (since we always launch new features, we always have new corner cases, we make sure these are handled). And when it is ok; we set this apk as a legacy one on the play store : if you have one of these old Android versions, you are going to be able to continue using or even installing that older apk. Technically we can update it if we want to, but unless there is suddenly a wave of crashes or complaints we just leave it be.

Even for that app, the figures were roughly the same (and that's while being available in 150 countries, that was for a pretty popular app). For these legacy apks, we often had something like 10k installs, while the main app is in the dozens of millions (but since that app had a paid subscription, make the service work even for old device was a must do).

And yeah, even for that job where we had an app available on API 7+ (Android 2.3 eclair IIRC), the figures were still pretty similar and fragmentation was something I read about in stupid articles, not a part of my daily job. I am not working for Google, if I had to solve fragmentation issues everyday, I would be the first to complain about it. I am here to build an app, not maintain random OEMs hacks.

CI systems only need the "centralized" copy as a reference point of what the current master is. Everyone gets their own entire copy of that repository though. If the truth suddenly changes it's known. I also know that if the copy in the "centralized" matches my own then the CI is also running exactly my code. If the centralized machine fails I can fail it over to any copy on any machine. That seems pretty distributed to me as compared to the original "distributed" version: e-mailing source code around. Version control like SVN and CVS were centralized in that me having a copy of the source and you having a copy of the source indicated nothing about whose version is correct. Moreover a failure of the central spot in the system is fatal unless you had backups as a form of pseudo-distribution whereas in today's version control a failure on any one machine is irrelevant to the preservation of the system.

One of my top ten favorites on HN, ever.

Why? It's history from a time when most people did not have access to the Internet (when there were no commercial ISP's, no fiber or cable to the home that carried digital signals), and BBS's were the only way you communicated electronically with groups of people via a mostly text-based computer...

it depends greatly how Kasparov tells you what to do. if it's "do this because I'm kasparov", or "do this, because your next move could be this and it gives you this opportunity". same with software. someone telling to do this because I'm senior engineer is appeal to authority.
Oddly enough, the challenge of estimating who is "ahead" is kind of like traffic. Intel arrived at the scaling traffic jam way before anyone else, and has been slowly slogging through it. New entrants are catching up to the traffic jam and will have to make their way through it as well. If there is no breakthrough, then everyone will find themselves more tightly bunched in feature/performance curves than they have been in the past.

The spoiler though is that different architectures have different scaling properties and limitations. IBM's Power architecture has already scaled past where Intel is, not because of the semiconductor process, but because the architecture is more streamlined. ARM is somewhere in the middle, it started off pretty streamlined but it has been adding warts (special instructions) to more directly compete with Intel and that creates impediments to scaling.
Depends on what you mean by "major", but Metafilter is one example that comes to mind.

Honestly, though, I think "major site" and "good community" are in conflict. Facebook's revenue is something like $0.12 per user-day. Twitter's is circa $0.07. It is at best extremely difficult to do effective policing of users with that kind of money to spend.

You can use ML, etc, to do the first cut. But real anti-abuse work basically requires humans. (Or not-yet-existant strong AI.) So my general take is that ad-supported social media is a dead end as far as real community goes. Doing it right takes either real money or dedicated volunteers. And probably both.
Then you can agree with me when saying that it is something worth attempting. It may be a great alternative, or another failure. We won't know unless we try!

(It was nice to have this discussion with you :) )
I don't know if its any more isolating in the general sense (I have my own anecdotes about all three kinds of places). But I think the phenomenon of these kinds of gig jobs being predominantly (or targeting) otherwise idle suburban house-wives is incredibly fascinating and seems to be digging at a deeper underlying phenomenon.
