Small telescopes are very useful for searches for extremely faint, diffuse galaxies because it turns out that these searches are surface brightness limited rather than being magnitude limited like most surveys. Surface brightness is a little counterintuitive because the minimum surface brightness a survey can find is actually independent of telescope size. Using a 8-m telescope is no better for finding a diffuse galaxy than a telephoto lens. The only thing that can improve your signal to noise ratio is observing time and observing time is much cheaper on a small telescope.

The basic reason for this is that as you increase the size of your telescope, not only does the collecting area increase, but the area of the image increases as well. So if you're looking at a diffuse source like a galaxy, the increased number of photons gets spread out over a larger area and the total number of photons per pixel remains the same. This isn't a problem for point sources (like stars) because even as the image size increases, all the photons from a point source still fall in the same pixel so the source appears brighter to the detector.

As peter303 also mentioned, refracting telescopes don't suffer from the same artifacts that reflecting telescopes do, which is why these surveys use small telephoto lenses rather than small reflectors.
According to the graph in the OP, battery-powered EVs have roughly 1/2 the lifecycle emissions. That's certainly lower and a good thing, but not a fundamental change given what needs to be done.

I'd have to do the math, but it would seem that the switch from gas to electric is roughly as beneficial as the past switch from carburetors to fuel injection. It looks incremental rather than revolutionary. And I think there is much improvement to be made. These numbers are American cars, so I assume they aren't diesel and are for generally larger cars than in europe. Has a diesel-electric hybrid ever been sold in the US?
The rest is mostly natural gas, and virtually no coal. I'm jealous! (Here in Virginia, it's about one third each of coal, gas, and nuclear.)

I noticed this doesn't include the 60g protein and the 32oz gatorade in the notes at the bottom of his diet.

There's not really anything special in there either, it's basically Meat + Rice/Potato + Vegetable - which is the diet I grew up with and what I would consider typical American diet (although maybe I lived in a bubble).

I see it all the time (some of our wonderful ad partners have been slow to drop `document.write`), but they easily become noise.
Excuse me, but how much is it a Bitcoin problem as opposed to being a Bitcoin ecosystem problem? You can't blame Bitcoin for every problem with each exchange.
Interesting article. But none of the problems described are actually with bitcoin. I see criticisms of CoinBase, WB21, TradeZero, Bitpay. All the problems were due to issues with exchanges & intermediaries and with handling USD. It seems the actual bitcoin part worked fine.
I'll pose a question to get things started:

What do you think of the argument format that Sequiturs uses, namely, a series of premises and conclusions?

I think this format has enormous value. It makes an argument much simpler to parse, compared to reading paragraphs, and if I disagree with the argument, I can easily express my disagreement by referencing the specific step(s) I disagree with. It has a lot of other neat advantages, such as allowing arguments to build upon each other, or to contradict each other, very precisely.

On the other hand, we're not all used to breaking arguments down into this format. You might be familiar with it if you took a philosophy or law class, but otherwise there's a bit of a learning curve. I believe the benefits of the format clearly outweigh this learning cost, but it's an open question what the market thinks about that.
When I was in New York this summer I carried around a sweater because it was too cold in the subway. It was 30-33°C outside most of the time (the Google machine tells me that's 86-91°F). It's true that the subway stations were miserably hot, though. (I'm European, but you can probably tell from my complaining about American air conditioning)
What good is Bitcoin if the ecosystem is bad?
Thinking about this a bit more, there's an interesting startup opportunity in matching the supply and demand of charging points. Some sort of sharing economy marketplace for renting out your parking spot that has an EV charging point.
I'm currently on a 40% protein, 20% fat, 40% carbs split, which is pretty common for male lifters who trying to lose weight and increase strength at the same time. For a powerlifter, this might be combined with around 40 to 50 heavy sets per week.

The high protein numbers are intended to support muscle protein synthesis. (I could drop to 30% protein according to most studies, though.) The high carb numbers are intended to support muscle glycogen replenishment and still leave me with enough mental energy to actually write code for a living. The low fat numbers are simply because something has to give.

It seems to work. It certainly works much better than my previous macronutrient breakdown, which had less protein and less carbs, and which left my lifts stalled and left me feeling like roadkill.

Anyway, eating a large quantity of lean protein is boring and time consuming. It's easy to blow 2000+ calories on fast food meal, but if you eat 800 calories of lean protein a day, it requires planning and work.
If a piece of information is telling you what to do that's your own problem. Other people may actually prefer it when they have are able to make informed decisions.
I used to live in LA, now I live in Austin and travel all over Texas for a living. I have no idea what you're talking about.

Texas has shitty roads that are way too narrow and full of potholes, a non-existent public transport system, and quite a few more homeless people per capita than SF. The difference with the last one is that you don't see them as often, because Texans aren't nearly as tolerant as homeless people as Bay Area residents, so the homeless hang out in places such as highway underpasses and the wilderness areas surrounding the cities. You know, out of sight of the rich.
That is why my priority is to have a home of my own, so at the end it won't matter if I'm broke, I'll still have a roof over my head.
My wife and I constantly have deja vu, like once or twice a month. What's strange about ours is that it always comes with a vert intense feeling of impending doom. Every single time. It's been happening to us for years. Being religious as we are, we have our suspicions that there's something more at play here, some nefarious invisible cause. Or maybe it's just some wires in the brain acting up. We don't really know, and it doesn't really matter, since the only thing to do about it whenever it happens is, well, nothing.
It is $200 this month. Chances are they will increase the price or put a cap the following month as they did in SF. The SF subscription isn't all that attractive anymore.

I've been through plenty of bulks and cuts, and it's very easy to eat a surplus if you don't impose silly limitations on yourself.

My personal preference is to blend the calories and drink them:

- Milk
- Oats
- Peanut butter
- Banana
- Whatever else you like (flax seed, whey powder, etc.)

Plenty of calories, good macros, and very easy to consume in large quantities.
Not saying that won't happen eventually, but it seems a lot more likely to me that on-street public charging facilities will proliferate as EVs gain popularity.
For fun -- you can almost get the "MPGe" equivalent of a Tesla S in a Geo Metro or Honda CRX

The way things work now
Bitcoin was never intended to reduce the cost of Banks, but rather supply an alternative.
Good point. It's quite possible that there's a fundamental limit to technological achievement and that we just haven't reached it yet.

On the other hand, I'd like to say that it's also possible that some particular processes can follow exponential laws without any restriction. It might be somewhat hazy, but what if outside of a few measures (infant mortality, life expectancy, etc) economic progress is nothing more than a subjective measurement of how present consumers value past output?

I'm not saying anything new here, both Easterlin's paradox and the idea of a "hedonic treadmill" support the idea that more income doesn't necessarily equate into increased happiness. And specially in the case of economic innovation, which might not actually be technically interesting or require any "new physics" at all - just mashing some current technologies into a marketable product - it might never ever stop, and will just degenerate into an endless chase of ever changing fads. Past economies wouldn't be particular poor, just particularly quaint, and a repository of dead fads.

Interesting article. But none of the problems described are actually with fiat currency. I see criticisms of the Fed, Banks, Credit Card Companies, Credit Unions. All the problems were due to issues with exchanges and intermediaries and with handling USD. It seems the actual fiat currency part worked fine.
In a pinch, I used to take a bunch of greens (spinach or kale) and dump black beans, salsa and some cheese on top, and throw it in the microwave. For breakfast, I frequently do something similar, by putting a lot of greens, beans, salsa, and cheese on top of eggs in the skillet. Put the lid on it until the cheese melts or the eggs are cooked to your liking.

Leftovers for lunch can be cheap, healthy, delicious and basically no-prep. For a low-carb option I like sauteed Brussel sprouts, green beans and protein (pork or tofu are my preferences); if you have a big skillet you can cook that and something else on the side for 4 meals (dinner and then lunch for you and your dining buddy). You can experiment with seasonings to your liking, and add some variety by picking seasonings (ginger, spices, soy sauce, etc.) from a variety of regional cuisines.

I'm curious what you mean by "isn't going to end well." I don't want to spoil the book. Anyone who hasn't read it really should as it's an excellent read.

But, at any rate, the Charlie character starts off as mentally very simple and enjoys life, then after attaining intelligence quickly achieves many things most people wont in their whole lifetimes, though isn't super happy while doing these and insults those he feels are less intelligent, though eventually grows emotionally through them, then he returns to being simple and happy.

Really this is just everyones' life, starting as a baby and returning to dementia as an adult, for Charlie it's just flat and then a sudden spike rather than a gradual curve. Curious why you think it wont end well. I mean in the end everyone dies so it's true if you're very much against that, nothing ends well.

The real point of the book I thought was we shouldn't view the super intelligent or super simple as better or worse because we are all both better and worse cosmically. So ultimately everyone should stop being condescending generally.
This article doesn't have any real discussion of Bitcoin itself, only the services that currently exist around it.
Yeah, that would explain a lot:

Available At Participating Dealers In California, Oregon And Maryland In Limited Quantities.
It applies here because part of the problem with POOL is picking up so many other people along the way.
Perhaps unrelated, but is the Tesla Gigafactory intending to produce "competitor" batteries, or are you assuming that GP was only looking at Tesla's? If the GP didn't get a Tesla, how would their factory be of use to him? (Actual question, not sure if there is an implication that the new factory will drive down prices for everyone).

Also, unless GP lives in an area where those sorts of garages are available, at least in the near term, they won't have anywhere to charge, which seems a fair argument against purchase. For instance, I live in south-eastern Wisconsin, and while there are charging stations within driving distance, there aren't any that would be convenient on my way to or from work, and I couldn't simply leave it at one and walk to work (or bus, because we don't do public transit here).

Known costs are known, less of a risk. It's easy enough to buy a new EV car if the other factors here are resolved, but I don't think it's unfair to say too many issues are up in the air at this point.
The number of people saying BTC is cheaper than Paypal continues to be huge.
It's pretty handy for money laundering and buying/selling illegal goods.
Yeah I had the exact same happen to me, really annoying. I understand they're just doing their job, so i can't really have a go at them for it either.

I would rather pay the extra for UberX now (or whatever it is called) instead of UberPool
If everybody used bitcoin for everything, then there would be no need for exchanges, payment gateways and the like. This stuff is added cruft.
While I agree that those fees are extravagant and the underlying process should have been much easier, it probably would have been prudent to investigate the process first, before starting it. I can't imagine being unaware of fees associated with using Coinbase before perusing their services.
I don't think USD -> Bitcoin -> USD is really the way to go on this. If you are trading in USD, why would you move it into bitcoin and back again? You already had it in USD.

If you need to buy some groceries in the US, you wouldn't trade your USD for CAD (Canada money), then bring CAD to a grocery store that also accepts USD. You would only bring CAD if you already had CAD.
Interestingly I was getting occasional black screens (i.e. the entire screen, status bar and all) in Safari on iOS 10. Not seen that on any other site before.
American Exceptionalism is the card being played here.

It effectively means: "Our country is fundamentally different from your country, so what works for you won't necessarily work for us. Your success or failure is no reason for us to follow your example."

Often this card is played despite the "fundamental differences" not necessarily being all that pronounced, or all that relevant. No two countries on this planet are identical, yet an astounding number of policies translate generally well despite that.
Bitcoin does not exist in a vacuum.
This article doesn't have any real discussion of Banks itself, only the services that currently exist around it.
There seems to be a trend in articles claiming some technology is bad/a disaster/dead when really it's just someone uneducated in the platform trying to use it incorrectly or with misinformed assumptions.

Bitcoin is still an emerging technology. You can do things with it you can do with _anything_ else. You can create 100 wallets right now and start receiving bitcoin to them. Please show me how to do that without interacting with anyone with traditional bank accounts.

Bitcoin is here to stay and we're going to continue to discover interesting use cases for it. Sorry this guy is bailing before he learns what it's all about.
Only issue there is it will more than likely no longer be "your" car, but a paid service like Uber.
You missed the point of my post. You are going to have one of the two issues, either looking through two index or indexes including the a large PK. At least with InnoDB you can make the choice. The strategy I suggested gets you the desired outcome of not including a large PK in all secondary indexes.
That's interesting, I turned up 1% and then didn't look any further.

In the same paragraph where "Higher Dimensional Black Holes" is mentioned, the journalist hedges the outlandish suggestion with "But no theory yet captures the whole story. “I do not think that there is any remotely credible hypothesis proposed at this moment in time,” Zaanen said."

So... "Yea.. uh huh... interesting concept, not a chance" to paraphrase.
The point you have missed is that we don't need these intermediaries if fiat currency is taken out of the mix.
Seems like this guy should have had some idea what he was doing before he trusted $6k to it.

He's also bitching about an overall 4% fee, which isn't a whole lot.
The difference is it's perfectly possible to use Bitcoin on your own without dealing with intermediaries.

But you can't send cash over the internet.
Do we really care how well the car did, rather than if what it did is safe?

Instead of generated data, try hallucinated data using AI to generate weird situations. Albeit random training is also pretty good, as is parameterization.
Any statement that begins with, "if everyone..." is a fantasy.
Because one of the espoused values of Bitcoin is the ease of transferring it across international borders.
It's rational to say that "all other things being equal, I should choose the one that I'm most likely to be unconsciously biased against."

Forget racism or sexism, that's how I choose software, which movie to go see, or which pair of pants to buy.
It's not about offence, I like to think HN can live without that kind of low brow smacktalk.
We chose it mostly because at the time, it looked like it had more active maintenance from the people at Mapbox, and it eventually looked like it was going to pass Leaflet.

I wouldn't say it's more complex. mapbox-gl favors a more declarative style (look into "Map Style" in the docs), but the concepts are not that different than Leaflet.

Web GL features (such as video support) is an obvious advantage, and part of why we chose it. We don't use plugins for this project, so can't say much about that.
The article illustrates a number of issues with services on bitcoin. One issue with doing things with any cryptocurrency is that it takes awhile for a transaction to occur. I had the preconcieved notion it would be as fast as sending an email but it really takes 30-40 minutes sometimes. Also, it seems the author is treating bitcoin as cash when its really more like you buying gold with cash and then transferring it back into cash to the other account that you want to transfer.
I love this strategy. One thing that I like about it is that the volume of vegetables you'd reasonably use makes it very difficult to over-eat on. This would be a difficult meal plan to use to gain significant weight.
That's a common misconception. The major task of process #1 with modern kernels is not, ironically, reaping children but receiving signals. Reaping orphaned children can be, and with several softwares is, the job of other processes.

I used TransferWise last time I had to move some money internationally, and had a good experience. Significantly faster and cheaper than wiring the money.
It doesn't need to reduce costs. If it performs so poorly that it's not a viable alternative, there's no alternative.
Would you feel better if NSA gets your data using a warrant signed by a secret court and gags Amazon using a NSL? Why do you think that US agencies can ask Lavabit to hand encryption keys, but the same can't happen with Amazon?

Comparing with the US I don't remember that France has any gag laws.

Fair enough. Taken as a global "never buy advertised food", I'd consider it a poor goal. In the context of the supermarket it mostly means don't buy frozen pizza and other premade food. Which I guess is fine advice in general.
Banks are an excellent piece of infrastructure, as it stands. If you don't need to use Bitcoin, or you actually care about what happens to your money, just use a bank.
His overall loss, including the drop in BTC price, is 4%. I wouldn't call that extravagant.
Thanks for the suggestion. I'll check it out.
This is especially true for people like me (starting in November) who take the metro trains into Grand Central or Penn. The transfer to the subway from those is almost frictionless.
> Violence needs to--has to--be met with equal or greater force to show the thugs who is boss

There may be some truth to that (or at least the weaker position that proportionate violence is necessary for this purpose), but even if this is necessary as a response, it is manifestly not sufficient as a preventive measure. Moreover, it is pretty much absolutely guaranteed to make the problem worse if the violence on the part of the "legitimate" authorities is not exquisitely carefully directed at the appropriate targets, because when violence that may be justified when used against "thugs" is misdirected at people (and those who such people care about) who are not already, but are at risk of being, alienated from the system, it often effects their alienation. [0]

And this is how legitimacy of the authorities -- which is almost precisely the extent to which people are not alienated from the system -- breaks down.

[0] In fact, this is also a problem with disproportionate violence of the type you recommend even when appropriately directed, which is one of the reasons that the argument that disproportionate violence for exemplary purposes is necessary (even if not sufficient) is dubious.
I find it amusing that you consider the internet "on your own" like there isn't a gigantic investment being made into that infrastructure that even enables bitcoin in the first place.

Do people who are in to Bitcoin think intermediaries solely exist to extract value from transactions? There's actually a service being provided.
Has anyone tried a self driving car in Manhattan rush hour traffic (or similar cities)? I assume SV rush hour is more slow moving traffic/etc on expressways rather than tiny congested streets.

In any case wouldn't their self driving car implementation be improved by a better mapping and navigation algorithm in dense traffic?
As the essay posted so clearly demonstrates.
What an ignorant article. It's unrealistic to expect cryptocurrencies to behave as flawlessly as wire transfers. The technologies need to mature. But for those with patience, they're pretty awesome.
No. I'll check it out. Thanks for the suggestion.
Why 40% in particular? 300 grams of protein per day, every day, sounds incredible (~1.5kg lean meat), is there some science explaining the effects of such amounts of protein?
Banks are alternatives of each other.

Don't like Paypal? Use Dwolla. Don't like Dwolla? Use Bank of America for direct transfers. Don't like BoA? Use Venmo.
