It's really hard to write benchmarks of an RPC system that mean much, but the overhead is really just in serialization. We have services that handle tens of thousands of requests per second on Twirp in one process.

Serialization/deserialization of a typical protobuf struct takes a microsecond or two, but it generates some garbage, so GC ends up slowing you down if you try to go really crazy and push past 100k req/s in one process with non-trivial message structures.
Yeah of course but what makes you think the other branch survives? No guarantees there.
> One more vote in the senate and they can pass a bill to do this

Which would matter a lot more if the US had a unicameral legislature with no executive veto; the Senate passing a CRA bill shooting down the FCC repeal of open internet rules would be a potent symbol, but have no binding effect since it has near zero chance in the House and, doesn't have the supermajority in either chamber needed to survive a near-certain Presidential veto.

Your assumption is frankly incorrect.

Physics is generally expressed in terms of differential equations. This is not due to their analytical tractability - as anyone who has attempted to solve PDEs before will know, most (nearly all) differential equations do not yield to analytical solution. Perhaps you think that quantum mechanics demands a discretized view of reality. This would be a complete misunderstanding of quantum mechanics, and physics in general.
Ask HN: Computer science related jobs that work primarily outdoors/'in the field'

Thinking of jobs like Field Installation Technician working at Verizon or another telecom. Substation Engineer who is responsible for the infosec/comsec security of some public utility or something.

My "guess" has always been a bad taco truck (or the like). Something that maybe the locals are used to, but makes the Americans ill.
The request usually won't be _explicitly_ solicited, but there are other cues you can pick up on (ie flirting). Of course people can read general friendliness as romantic interest (or vice versa), but you can have at least a decent guess whether someone will be interested in going on a date with you. In some contexts it doesn't hurt to ask when you're unsure, but at work it's better to err on the side of caution (doubly so if there's any power difference between your positions).
I actually appreciate Jazz more than classical, and I’m sure I can play Jazz if i put my mind to it. Would that make my brain work differently before I even play jazz?
A better way of looking at it might be "What proportion of software in daily use" is open-source.

Sure there's a lot of proprietary software, but that's not an 'open-closed source' dichotomy where closed-source stuff can be sold for profit, it's a 'public-private' dichotomy instead.

That is, Banks will keep their source-code private to prevent other banks from stealing their ideas, for example, and nothing to do with the software itself per-se.
The other side of this is cells are also really fast. Modeling even 0.01 seconds could be very useful.

btw BSA now admits girls too. So maybe not the best example.
And Bitcoin Cash will need GB or even TB sized blocks to scale to the size of Visa. If scaling the network was as easy as changing 1 variable it wouldn't be that hard to get consensus on a scaling solution.
Wow, this is fascinating! I would love to invest and start a wireless ISP on the eastside of Seattle. Suppose you have an area that is flat with lots of exposure, where everyone hates Comcast (maybe that last part is superfluous). I would think you'd find plenty of programmer customers if you have a say 200 mbit wireless connection without bandwidth caps (or maybe something insane like 10 tb/month). This seems like a much better area to invest in instead of putting more money in my 401k. It's not so much much money, less than two year's 401k contributions to run it for a year and see if it catches on.

I hate comcast with a passion, they are on the only provider in my area. Here's another fantasy, I imagine two points of presence, one at my house. I run fiber to my house as part of this business, then I've got infinite capacity. Who's up for this?

How much does it cut out if it rains, probably that is a problem here.

I think you mean buy $6800 :)
That's just not helpful. Money circulates around the economy. If I buy a $10k car I don't say the car cost my employer $10k.
4.5bn / 15 / 13,000 = $23k cost per job created, give or take, plus the chance for a boosting of local manufacturing. That seems perfectly reasonable.
> Also your argument talks about bitcoin but not the other cryptocurrencies that might not have the some of the features you describe.

You asked me to explain bitcoin, I did.

> Overvalued compared with what? Speculative is an opinion.

Overvalued compared to its utility as a currency, which is what it ostensibly is. As a currency it presently has no value because the overall BTC valuation is so high and so unstable, paired with the transaction fees and delays.

Speculation is not an opinion here. Look at how many people are "investing" in it with no comprehension of what it is and what it does.

> Like being able to exchange with literally anyone in the world is unprecedented.

For all practical purposes I can exchange Euros and US dollars with anyone in the world, modulo a few countries that have stricter and enforced policies. I was in Uruguay last July and was able to use USD at shops because the other option was credit card (exchange rate set at the end of the day) or ARS (cash on hand) and the exchange rate was better with the posted USD->UYU was better than either of those (as long as I used at least a $20 bill). No questions asked, they just took it and I got the goods I wanted.

> I can trade with North Korea with it.

I will agree that it does eliminate or reduce the effectiveness of economic sanctions in some situations, like this one. However, if you're a US citizen conducting business with NK is still illegal or tightly controlled, and bitcoin is only pseudonymous. And with regard to opening up financial interactions with people across borders, that is a potentially very useful thing. But at the moment it is not a feasible thing with bitcoin.

> The backing part of commodities is greatly exaggerated. Who cares?

The people seeking profit off of them. If a commodity doesn't have something behind it, its value will fall. When it will fall can be a while in the future depending on the general hype and/or confidence. Bitcoin is all hope, no real confidence, and no real utility (at present).

> You talk about BTC but like BTC is not the end all.

You asked about bitcoin, I answered about bitcoin.

> As a trading instrument it's so much better than stock. With stock you have to wait three days. I guess the closest is Forex but forex is just so boring.

Three days? Three days for what? And better in what way? In the "I enjoy rollercoasters" sense? Then sure, it's better that way. At least with stocks (or the ones I invest in) I can examine the fundamentals of a company, the global and national economies they play in, and have some idea of whether they're overvalued or undervalued at any given time with ease. Most Forex is the same.

Bitcoin, the thing you asked about, is not useful as a currency. So it's only useful, right now, as a commodity and in trading on various exchanges as a commodity. It is pure speculation until the value on those exchanges and the value of things I can purchase with are closer together than they are today.

What's the "rational basis" for a specific value of the P/E ratio?

There are many stocks that belong to companies that have no mechanisms in place nor could they be reasonably expected to introduce mechanisms to directly return profits to shareholders. These stocks have the same form of "intrinsic value" as gold or Bitcoin: whatever the hell the next person is willing to pay for it.

Pretending that an underlying asset that doesn't throw off any yield or return of capital is somehow more rationally valuable than another doesn't make sense.

A few guesses.

1. These things cost money and resources to initiate. EFF may see this as going nowhere†, so why spend the time and money?

2. EFF can always file a brief if the case ever does go to trial.

3. Almost forgot: Mozilla wants the PR.

†Here's Mozilla's claim:

> Mozilla seeks review of the Order on the grounds that it is arbitrary and capricious within the meaning of the Administrative Procedure Act, 5 U.S.C. §706, it abdicates the FCC's statutory mandate, and it is otherwise contrary to law.

IANAL, but I'm pretty damn sure the FCC can come up with a few decent arguments about why they're not behaving in an arbitrary and capricious manner...
> It served 23 million different passengers, itself a 92 percent YoY increase

Wow.
in my view the first stage of SpaceX Falcon is the thing which is most close to the hypersonic transport today. One can imagine that such reusable stage would accelerate the high-altitude/suborbital plane thus solving the task of having engines for different regimes. Cost-wise - the few millions such a reusable stage launch would cost isn't that far from ~$35K/hour costs of SR71 on missions of 10+ hours.
It's likely that was the reason - though I do see a problem with it.

If you follow that line of thought to the end, you end up in a world where you can only run a program on your computer if the vendor has a business relationship with your OS vendor (or is more powerful than they are).

Say goodbye to general-purpose computing.

The wind doesn't cut through proper clothes. I try to avoid the roads as well, but the bike paths work well where I live, even when the temperature goes down to -20°C.
What's the point you're trying to make? Cuecat is a product. It's not an industry, medium, or platform, like TV and radio is. Your quote is a false equivalence.

Try to setup a payment solution that can be used world wide. Including the necessary banking. This is a use case where cryptocurrencies really shine. It is basically effortless comparing to the alternative (i.e. legacy banking).

Just my two cents after spending months dealing with banks and PSPs.
>All the things I want to do that I value more than driving.

This paints you as a very limited person if you are living in the US, because the "things that you want to do" exclude:

-pretty much all the great outdoor activities and nature that the US has to offer (National/State Parks);

-getting to know your own country and traveling within it

-going to any place or event outside the city (for most people, shelling out $100+ on Uber each way is a barrier)

I know where you're coming from, I used to live in NYC and didn't drive. I got my license when I moved to TX for grad school at the age of 24 - and I didn't even need it to get to work (I've been biking to campus for 7 years). But I did use the car for all the "rosy" things, and with that came the realization of how much I was missing out on.

The thing is, you don't even know what you are missing out on. You are a person who doesn't travel, and says they don't want to. You are practically tied to your community. How often do you get beyond the 50-mile radius of your home? 100-mile radius?

Now, if you were living in Europe, that wouldn't be the case. You would be able to travel without owning a car. Owning a car there has smaller marginal benefits.

But you don't live in Europe. Public transportation in the US is horrible, even when you add a hefty dose of Uber/Lyft to it. It's a sad state of affairs, and I wish it weren't that way. I support public transport initiatives when I can.

Choosing not to have a license is voluntarily confining oneself to a very small subset of the country. Uber won't get you to the Rockies. A rental will (so you don't need to own a car), but you still need to drive it.

Yes, it's a hassle (at first; after some time, people start to enjoy it). Yes, it takes effort, time and money. But to say that you don't WANT to have the benefits it gives you in this country, one must at least somewhat be aware of what they are.

Of course, to each - their own. But I got to see the total solar eclipse. And you might read how amazing it was in a book on a train one day.

PS: I apologize for the somewhat-deliberately provoking tone. On a softer note, have you read "On The Road" by Jack Kerouac? If so, do you honestly say that you want none of that? If not, you're in luck, because reading it is a marvelous experience: https://en.wikipedia.org/wiki/On_the_Road

This book is culturally significant; but as a side effect, it might change how you see driving.
I've done the math, for sure. It would cost me $1000 per month to use Lyft or Uber for my commute. That's almost exactly twice what my running costs are for owning my commuter car.
Oy. Who wouldn't have understood the inherent risk? Bet big, sure...if you're up to it, but don't bet the mortgage.
What could make this really take off is an in-browser JS client. The simplicity it has added seems to really help there. The gRPC team has had one in hiding for a long time only giving people access who explicitly ask: https://github.com/grpc/grpc/issues/8682 (good thing GitHub has a feature that snips hundreds of comments or that link would take a while to load)
I would love to hear more about your experience. Did you write about it anywhere?
>How do you know that it's the "E" that is wrong, and not the ASCII_A? Maybe it should be ASCII_E.

Ultimately you don't, but ASCII_A requires double the intentional actions to name it and have it also be 'A', whereas 'A' vs 'E' or whatever else is a much easier typo.

It's the whole idea behind NOT having magic values in your code. That is, that:

if (temp > 212)

tells us much less than:

if (temp > WATER_BOILING_TEMP)

and that we can more easily spot an error with:

WATER_BOILING_TEMP = 275

than with:

if (temp > 275)
The question is why don’t they collaborate and unify the efforts?

It seems it should only not happen for a handful of reasons.

For example, if there were real intractable philosophical differences, if someone risks losing strategic advantage, or if competing is driving better results than collaboration could.

Yet it’s not obvious to me how any of these are true.

For many projects unification wouldn’t make sense by a mile even for reasons not listed here.

I don’t even see how the existing skill sets are tragically different, say like the the skill sets are so different for Linux/Windows admins who could never master the other’s job in a week.

In this case maybe there are reasons for separate projects but are they really super compelling?

Imagine the (potential) upsides of having more resources, less confusion, and more
comprehensive tooling support.

To me they are both useful projects but I don’t see any fundamental advantage of one over the other that would make me lose sleep if everyone rallied behind a single effort.

Hitting the brakes too hard can be just as bad as hitting the throttle too hard.

If you're hydroplaning, or if your car is sliding on ice or snow, the last thing you want to do is hit the brakes. The only real course of action is to try and ride it out, especially in a rear wheel drive vehicle.

As an aside, as the question of the article is more about the mathematics as opposed to the physics: Navier-Stokes assuming a continuum is one of the fundamental assumptions made in basic fluid dynamics, and to an extend applies to the governing equations for solid mechanics, in a whole field known as Continuum Mechanics.

The continuum assumption, as it turns out, is actually incredibly accurate for most gasses that are comprised of discrete molecules. Specifically, the region in which N-S is valid for is when Knudsen Number[1] is less than about 0.01.
Knudsen Number essentially characterizes how densely packed the particles are.

This turns out to be most of the flows we observe on Earth. N-S becomes less accurate at around Kn = 0.1 and completely useless at Kn >= 1, as in this region the differential arguments no longer hold and NS predicts something non-physical. Some examples of flows in this regime: mass spectrometer, reentry, and inside shockwaves. In that view, you're not wrong that NS will eventually fail, but it is just applicable to most of what we do. For those working with fluids, it is important to recognize for when NS fails so they can switch to a different model for solutions.

For higher Kn flows, such as Kn > 10, you can feasibly track individual particles and their trajectories. People do this for satellites and what not. However, between the range of 0.1 < Kn < 10, we do not have a good enough set of models that is able to compute accurate answers to reality with reasonable time frames and is an active field of research. If you're interested in learning more about this topic, look up the Kinetic Theory of Gas, where particles are accounted with the evolution probability distributions in temporal, spatial, and velocity space.

Google's job is to make money, and to grow and make ever increasing amounts of money, not to find stuff. If Google decides that it's worth it to lose some of its customers in order to reduce costs, then it's fair game for them to do so.

Maybe a competitor will come in and steal marketshare from Google by filling the hole Google leaves behind when they increasingly make changes which annoy a subset of users (duckduckgo is probably closest, and I use it as my default search engine, but I don't find it's as good as Google yet in a lot of cases). Maybe enough people will switch to be an issue for Google, in which case Google miscalculated the cost of pissing of that subset of its userbase. Maybe so few people will switch that it's offset by the cost savings of not keeping everything indexed, in which case it might've been the correct decision, from a capitalistic point of view.

This focus on constant growth is the issue with relying on companies and capitalism, but that's a bigger discussion.

I think there's a distinction to be drawn between mobile _apps_ and mobile device support. It is important to note that often the reason a mobile app exists is for reasons other than to provide features to the user. For example it is easier to monetize users with an app (you can do in-app purchases and plague the user with push notifications to drive engagement). Users are more likely to stay being users with an app. You can support social type interaction such as taking photos easier. None of this matters much for enterprise applications.

Therefore most of the time a simple mobile-friendly web app works fine for enterprises.

So let me get this straight. Gold can be compared to bitcoins in terms of scarcity and and store of value. But bitcoin itself is in practical term a proof of concept technology that is only useful when applied properly in another block chain. While gold actually has great uses. Can i say if you are investing in bitcoin, you are basically investing in equivalent a scarce physical paper with not a whole lot of use?
