Whether you see the value or not, there is a robust secondary market whose history shows that there is strong demand for used devices and that their entire value doesn't evaporate in a few years.

And if I'm wrong about 50% depreciation being typical over 2 years, I'm not wrong by much. There is not a huge difference between 70% depreciation and 50% in your monthly cost of ownership. Undamaged 64GB iPhone 6s are selling for between $230 and $310 on eBay, so that's 60-70% depreciation. On average the 6s cost about $20 per month.

Output noise in addition to intended output. The 'noise' is the information discarded by the logical operation and must provide enough detail to recreate the input conditions from the output. So if an AND gate and the result is 0, you need the noise to contain enough information to indicate whether one of the inputs was 1 or not.
We fix the largest problems that we are permitted to touch.

We cannot propose a solution to the ultimate cause, because that would require the representative democracy to elect more scientists, technicians, engineers, and mathematicians to the legislature in lieu of the usual professional politicians, lawyers, corporations managers, and educators.

So we work on what we can reach.

We cannot create a proper healthcare system from the top down, but we can issue bugfix patches and hope they get adopted upstream. That keeps the system limping along, but never getting quite bad enough for anyone to demand the complete overhaul that it needs.

It only looks crazy because the biggest problem any motivated individual can solve is limited either by the amount of investment capital they can attract with their solution, or by the amount of campaign funding they can attract with their solution. So any proposals that threaten profit margins cannot be considered.

Most coin mining is not practical on home computing devices. Wasting the power generation in this way isn't necessarily the best investment of the surplus power.

Also... realize that this is power to the local utilities is negative cost - not the power to someone's home. They're still paying retail rates. I would be most disappointed to have the power utility turn on something that causes me to consume more power (be it cryptocurrency or all the lights in my house) when I'm still paying retail rates.
The time savings provided by cars, once you factor in time spent to pay for them, pump gas, perform (or wait on) maintenance, plus actual travel time, is dubious

I call shenanigans on this. How much time do you spend pumping gas? I doubt I spend more than 5 minutes a week, maybe even every two weeks.

As for travel time, just other day I was thinking, my 30-minute journey would be a day's walk probably, starting and finishing in darkness. And carrying all my stuff on my back I would have been exhausted at the end, if I'd gone cross-country instead of on metalled roads, instead of arriving in no time feeling fresh as a daisy. If the weather was bad perhaps I couldn't have made the journey at all, on foot.

And as for maintenance, well, I have a Toyota, so that doesn't take much of my time either!

I think you are dodging the central claim against Apple, they prohibit competition on their platform. If Microsoft or Google did this, they'd be accused of anticompetitive behavoir, or being a monopoloy.

In fact, MS actually did this with IE vs Netscape. Maybe you are too young to know or remember this. It's just astonishing that anyone could ignore the parralels.

Also, I asked if there was any "technical reasons" Apple couldn't allow real Firefox in iOS, and you ignored that. I suspect because you know the answer is "no". So, then it's purely for marketing reasons.

Please explain how it's better for end users to have only one choice of browser? If you want to say they already do, then you do not understand how browsers work. And if you want, I can do some googling for you to show you why FF and Chrome on iOS are _not_ any different at the core level than mobile Safari.

The 6S Plus was $750 for the most basic model at launch and now ebays for about $200 which squares with losing about half the value per year which is pretty normal.

Consider also the fact that the battery life will be substantially decreased from new and that most people wont be able to replace it themselves.

Something that is overprice is actually more likely to decline because 2 years from now its just a comparatively slow device that no longer serves as a status symbol.

This is one of the reasons that many argue for the legalization of prostitution. If there is a state-regulated market for sex workers, is is much easier to identify and prosecute sex worker slavery and exploitation. It also becomes possible for sex consumers to restrict themselves to the regulated market, and thus avoid contributing to the exploitation of women and children. Without such a legalized market, cases of exploitation and slavery are no longer easily distinguishable from voluntary and of-age prostitution.

London Ambulance Service policy states that ambulances should not to be dispatched to women in the early stages of labour unless there are known risk factors. It's a massive waste of resources to send two trained personnel and a fully equipped ambulance to act as a taxi, just in case something goes wrong en route.

Isn't 10 MW a unit of power and storing energy would be in MWhs or Joules? I understand that the grid needs to balance the power it is using, but to provide that power over time you need to store energy. Surprised an "electrical engineer in this industry" would use these terms, but maybe I just don't quite grok the lingo. An explanation would be great.

Yes - I found that to be true in my testing as well. The configurations optimized for highest absolute returns did very poorly in unfavorable market conditions (and max drawdown became significant), while there were some that performed moderately well and were much less affected by downturns in the market. Like most investments, it really comes down to the same thing: risk vs return.

Why not consider putting a good extender placed near your balcony?

I use one at my Dad's house (next door to mine) so that I can access my wifi. Our houses are brick, and in spite of that, the extender I got does a pretty good job. I've tried various extenders in the past few years, and they were all pretty flaky, but the latest generation of extenders seems to perform much better than older ones.

I'm using the Wirecutter's current favorite, the TP-Link RE450. Having said that, the RE450 was recently found to be spamming NTP servers with an excessive amount of requests.
> For some reason, NPS thinks that a 6 should be equal to a 0. Nobody else thinks this. Remember, if you worked at a company like Intuit, all that hard work to get everyone to move from a 0 to a 6 would not be rewarded. Your executive would not get their bonus. It’s as if you didn’t do anything.

This seems perfectly reasonable to me. Outcomes matter -- not effort -- and reaching 6 is not the outcome NPS wants.
> Well, let's let the author try to convince you that NPS is a harmful, horrible number to summarize a company's performance on.

This is not how it's used in practice. Meaning: No company measures performance based solely on an NPS metric. NPS is one data point among many used to measure company performance.

There's no more sense in demonizing NPS as there is in worshipping it.

"If we spend a second thinking about this, if 9 out of 10 startups fail, then we only need to roll the dice 10 times and the last startup will (by statistics) achieve success."

The article touches on the battery that is being used:

> In one case, it takes advantage of negative prices by being paid to pump large volumes of water into a mountain lake in Austria. When prices are higher, the company releases the water, using turbines to generate electricity.

This is Pumped Storage hydroelectricity - https://en.wikipedia.org/wiki/Pumped-storage_hydroelectricit...

Pump the water up when the power is cheap, use the stored water in a hydro dam when the power is expensive. The storage capacity is quite significant and while not as fast to respond to the grid as batteries, its substantially faster than other power generation systems when wind or solar power generation dips.
This is incredibly depressing. It hits home for me because I'm in a very similar situation. I and one other guy almost went broke making Clicker Heroes, but it turned out to be a great success.

But so far since then every project has not been worth doing.

> I didn't do ads, I didn't do micro-transactions, scummy energy bars, and all those other bullshit monetization tactics.

We did this in Clicker Heroes, and I don't like that we did. But I'm learning more and more that it's hard to compete against scummy tactics.

I hope Clicker Heroes 2 does OK. We might have to find corporate jobs too if it doesn't.

Not convincing, considering executives often set their own goals.
It's sadly ironic to me that a YCombinator commentator manages to be even more hyperbolic over gene therapy fear-mongering than an already very exaggerated message film.

Disparities in IQ between people and groups are already massive and it's not causing nuclear war. Disparities over how much time and effort are put into raising offspring between classes are already massive. Again, we're still not going to war over it. How would you even envision a nuclear war like that taking place, when the highest IQ people are spread among many nation states and demographics?

You should really try to tone back the over-the-top exterminist rhetoric and thinking, if only for your own well-being.

Not if I was 65 and still working, because I liquidated my 401k back when I was 30 and it never panned out.

But yea, I would regret being 65 and having never built a business.

I don't know. Probably, if you were able to dramatically cut costs and go into hyper-saving mode. This can be a challenge later in life though (once kids and a mortgage take hold).

"lots" of people is often used to justify lots of anecdotes. Apple didn't sell tens of millions of iPhone X's because it's a status symbol. There aren't millions of unwrapping photos and videos.

A big reason is that in a case it's hard to tell which phone you have, I've yet to have anyone notice I've got an iPhone X.

The iPhone X offers significant enhancements over an iPhone 8 and 8 plus. The difference in cost is relatively minor when amortized it over your ownership life-time. For some people, like my wife, it's still not worth it (esp. if you prefer TouchID). For me it was.

I think more people would regret it if they knew what they were giving up, but most would probably not make that calculation. If he had kept his corporate job and spent the initial $30k a year he could have retired early only 10 years later. Maybe less if he'd be willing to live very frugally. Then he would be free to build as many apps and games as he wanted, giving him many chances at getting a big hit.

I'm in this dilemma myself, as I've always wanted to do something more risky, but I don't want to jeapordize my ability to be financially independent at ~40. Being stuck in a potentially crummy corporate job with potentially terrible management and coworkers for another 25 years (not the case now, but things can change quickly) is the regret I want to minimize beforehand.
Richard Feynman published a lesser-known set of lectures on the subject of computation and he deals with this. The computational system he depicts is one in which 'computation' occurs as a intentionally setup quantum system falls to its ground state. It might take an arbitrarily long amount of time, but the computation will occur with zero energy loss. In order to get the result more quickly you can input energy and spur along the process. He also deals with the theoretical, and some of the practical, considerations surrounding reversible computing (which he stresses as critically important for zero-energy-used computing). I've always just considered it a matter of if X bits of information enter into a system and you are only preserving Y bits of them... the others have to go somewhere. Information is as physical as anything else, even though it can take many forms. We usually end up dumping it as heat, but we could have it be vibration or RF or maybe some weird geometry morphing (on the quantum scale I mean) all the same.
Actually, Samsung 960 Pros are fast enough that encryption becomes a bottleneck, at least on my Xeon E5-2620v4.

You can test it yourself with `cryptsetup benchmark`:

# cryptsetup benchmark --cipher aes-xts
# Tests are approximate using memory only (no storage IO).
# Algorithm | Key | Encryption | Decryption
aes-xts 256b 1874.2 MiB/s 2042.6 MiB/s

I was surprised and it made me doubt whether it's using AES-NI at all, but then again it's not an issue in practice.

You are right. fadeIn and fadeOut should have some optional callback for completion.
This article has the same blindspots as traditional breweries; it asserts "The most obvious difference is that lager yeast works best in cold temperatures -- temperatures that would make an ale yeast go dormant."

This is not a correct statement. A more accurate statement would be "The most obvious difference is that lager yeast - at lower fermentation temperatures than usual for beer - produces a more subtle, 'clean', taste that is easier to mass-market." And that's also not entirely accurate, but it's accurate enough for an article.

Anyone who has read "Mikkeller's Book of Beer" and noted the fermentation temperatures of their recipes will be aware of this.

If you brew a batch of size X, and then divide it into Y vessels, and:
1. Ferment at different temperatures in each vessel, say with a difference of 3-5 celsius, or
2. Ferment it with a different yeast strain ("ale" or "lager" strains) in each vessel,
you will get vastly different results in each vessel for both methods. Shockingly different.

There are commercial beers fermented with "lager" yeast at the higher end of the spectrum, like with White Labs WLP940, "Mexican Lager", which on its old packaging advertised a fermentable range of up to 23C, if I remember correctly. My most brewed beer is fermented with this strain at 16C.

There are commercial beers fermented with "ale" yeast at low temperatures. I ferment WLP400 at 4C, and it produces an exceptionally smooth taste with subtle hints of clove. There are many others as well that can benefit from lower temperatures, like WLP028 and some in the 5XX series.

The much, much more important thing to understand for an experimental brewer is what I demonstrated above, that regardless of an "ale" or "lager" label, two different yeast strains will produce vastly different results given the same conditions and wort - and that _one_ strain fermented at different temperatures will develop amazingly different profiles.

The reason this is important to understand is that noone will tell you. If you walk into a store, they'll give you a "standard" yeast that produces a reliable result - like US05. I've read close to 20 books on brewing, and not even the Mikkeller book tells you this as far as I can remember - it only demonstrates it by listing the fermentation temperatures of the catalogued recipes, and allowing the reader to get shocked by them.

And it's also important to understand because it's really, really fun to experiment with.

One of the best beers I've ever made was a WLP570 fermented at 33C. Unfortunately, this strain is exceptionally hard to work with, if your drinkers prefer a clear beer in their glass.
But I can't bring myself to lump the current day 'social media' (ie; Twitter, Facebook, etc.) into the same category as IRC.

How Bill Gates Uses Deep Working to Enhance His Productivity
Ask HN: What costs go down in the Bay Area?
I've participated in some of the recent threads on the price shock and anxiety of moving to the Bay Area, and for sure I'm nervous about my housing cost going through the roof, as well as having a very poor grasp of how to navigate SFUSD registration. For those, I think the strategy is to rent in the attendance area of the schools we want (spending more, of course!), as it seems the only factor we can control is the weight given to where you live.

Anyhow, I've also gotten to thinking through where I'll spend less in SF versus where I live in Maine, and I'm wondering what else I might be missing that I can look forward to?

Costs going down for us in SF -

Utilities - CA might be expensive, but it's not 16c/kwh + 1000 gal of heating oil expensive.

Car Registration - Somehow it's actually looking to cost less, even before going from 3 cars to 1.

Commute/Transit Expense - We basically drive two cars 50 miles each round trip right now, with work/school/kid activities. Muni and a neighborhood school will eliminate a lot of that.

Travel - The Bay Area has 3 airports with competition to more or less everywhere, even with UA having a fortress hub in SFO.

Weather - OK, weather itself isn't a cost, but clearing the driveway 20 times a winter isn't free, even if you DIY. SF doesn't have that problem. Not only does it not snow, but there won't even be a driveway!

Anyway, yeah, I've already figured out rent will be out of control, Muni will suck, etc. But there's a lot to look forward to - what else should we be adding to this list?
Not to be rude but I stopped reading at "MACD". TA is not the go-to strategy in stock trading for a reason. Indicators like MACD, RSI, Bollinger Bands etc re-paint a lot. So the perfect signals everyone sees on the charts are, for the most part, are just "profitable system" mirage.
