Those things are fun. The idea is that you modulate the outgoing beam with a RF carrier, and measure the phase shift of the incoming beam relative to the outgoing beam. Today you can do this directly, because electronics is fast enough to count in the gigahertz range. It used to have to be done by superheterodyning, like a radio receiver. You down-convert both the incoming and outgoing signals using a local oscillator, and get two new signals at a much lower frequency. This transformation has the useful property that the phase difference between the lower-frequency signals is the same as the phase difference at the higher frequency. But at the lower frequency, it's easier to measure the phase difference. Also, you get the selectivity of a superheterodyne receiver.

That's fine for a scanner, where you only need one copy of the electronics, but doing it for every pixel means something like a radio receiver behind each pixel. Still, you could probably do that now.

The SwissRanger [1], a short-range time of flight imaging camera, worked like that. It's been discontinued.

(I fooled around with this in the early 1990s, trying to build a laser scanner. Too many noise problems.)

Custom software development is not an unexplored market. There are literally thousands of companies, many of them small & local, offering those services. It's just that we do so to other businesses, since it's way too expensive to develop custom stuff for single individuals.

I've built a coin-operated electric candle stand[1] for a local theater group. I'm just an amateur at electronic circuits, and I'm sure a professional would have spent less time on it, but even at half my hourly price, I would have blown half their production budget.

You could say some builders would be willing to take a pay cut to work within your community, but frankly, doing one-off toys to upper-middle-class people is not my idea of community service. I'd rather have a well paying job writing B2B software and then work for free for people in actual need.

Hardcore ex Nano user here. I prefer Nano nowadays since it has more sanity in key bindings and Works quite well as a replacement for Nano.
I tend to pick different strategies for the amount of time I have of someones attention.

But you're advocating the one blow will be from the "personal health" angle. With little time on my hands I usually also go for this angle, simply because I believe that all the people who'd want to be vegan/vegetarian "for the animals" would be so by now. The health angle still has a kind of novelty/news aspect to it (while being more personal and urgent then the environment angle).
From what I can tell, this doesn't really help you know when your queued up lambdas have all completed, which is what GP wants.
The tech media (and tech startups) has this bad habit of hyping up technologies before they're ready for prime time.

They did it with 3D printing, they did it with VR, and now they're doing it with blockchain.
The security protections on the launch pads alone would have to be incredibly high. Looks vulnerable at sea like that.

My thought also, how will landing feel?
How big are the sonic booms gonna be?
It does depend on where you live. In US they probably do. In EU countries they probably don't.
All rockets (during launch) are more sensitive to lightning strikes than planes. That's a given: the exhaust plume conducts electricity.

Compared to F9, BFR is fatter and would have less trouble with high-altitude winds at launch.

Now landing weather, that's another thing.

Here you go - for a link to a national "corporate agenda" that applies to large companies, see the conveniently titled "2017 American Growth Agenda" put out by the US Chamber of Commerce, the major big business lobbying group in the US: https://www.uschamber.com/about-us/the-2017-american-growth-...

The fact that corporations battle with each other doesn't change the fact that groups of them work together to advance their interests, as above.
We have always lived in a corporate-totalitarian dystopia, though it has been called different names in the past, such as colonial rule, monarchy, feudalism, samsara and Babylon.
I have a PhD in physics, and this is exactly how I learned the material. I mean, really learned it. I did fine in plain math classes, but never quite connected with the material.

Calculus and linear algebra both really only 'clicked' when applying them in my physics classes.

Physics is like the "word problems" we'd have in elementary sho, but for advanced math.
The timeframes are pretty tight, so I hope there are companies already working on it. Anyone know?
I watched highly episodic TV shows like Rocky and Bullwinkle, and remember being excited for the next episode. My fiancees nephews watch anime and are super into the story (sometimes annoyingly so :) )
I think it just depends on what you watched.

She wanted two things. She wanted someone else to clean the house. This is fine. It happens all the time. But the second thing was that it still had to be done to her exacting standards."

Nope, you missed the point.

The point was the wife wanted a day free from housework, which isn't unreasonable. The husband screwed up because by doing the cleaning instead of hiring someone in (which was suggested they could afford from money she earned) he left her needing to do the rest of the housework, like looking after the kids. The end result = no day off.
I read that book like 10 times and I never got that. Thanks for the hint!
Like the security precautions at airports? Any airport that I'm familiar with has access roads and roads around it that are accessible to the public from where any idiot with an RPG or possibly even a rifle could attempt to bring down a passenger jet. And yet it does not happen.
Haul the CEO in before a panel of senators like we did with Washington Mutual. Or, better yet, nationalize Equifax.

He didn't actively facilitate the breach but he certainly precipitated it with neglect and terrible leadership. That's why he's stepping down to begin with.

On that note, yeah, you are totally defending him.

Passive aggressive-language like "for all those people scream at this as unjust" and "your knee-jerk", indicates you're (weirdly) assuming superiority over those who are unhappy about an obvious injustice. Or perhaps you don't view his crime as injustice at all: "make a huge scene and have the CEO exit furiously", yes that kind of drama would be totally unfitting for one of the most serious data leaks in history.

Don't patronize us.

Even without new amazing content, we still wouldn't have enough time in our lives to experience all the great films, shows, novels, etc. that have already been produced. So it's really a matter of how strongly you feel connected to and value the content's experience, and how it compares to the other joys in your life.

I recall that Buffett reads 5 hours a day, and I distinctly remember reading about someone in the humanities (maybe they were an author) who also read 5-8 hours a day, going through 200+ books a year.

Anecdata wise, I have a friend from college who's seen 1041 films since 2008 while holding down a fulltime job. http://msls.net/films/seen.html (He's slowed down quite a bit, since 3 years ago he was at ~800)

So you _could_ make this a priority like these people, but from the sound of it, as of now you might enjoy creating things on your own more than consuming other people's creations. :)
Considering that he is often compared to Steve Jobs in terms of his impact and innovation, I find it endearing that he doesn't have any of Jobs' glibness

Thats why they show the spaceport out at sea, as it kills the standard NIMBY objections. Also the cities they want to fly out of don’t have enough room to easily build a spaceport.
Yeah, there's many factors. It's not like removing subsidized housing would magically fix everything. It would make things better at the margin overall, more than the wealth transfer from developers to subsidized housing lottery winners.
One big limitation that was glossed over in the presentation is radiation exposure. The only time it came up was the mention of a 'solar storm shelter'. The radiation exposure during the Martian transit would be much greater than the same time spent on the ISS, somewhere on the order of 200mSv [0] (the composition of this radiation also contains significantly greater proportions of heavy-ion radiation, which appears to be more damaging, so this may need to be adjusted upwards). According to the wonderful xkcd chart [1], this would be in the 'probably no radiation sickness, but certainly not good for you' territory.

I would love to know what their plans are, since shielding is heavy. [2] seems to suggest electromagnetic deflection as viable (which would be insanely cool, and could probably reuse SpaceX's cryogenics work for superconductors).

Also, a quick search didn't turn up much on the anisotropy of interplanetary radiation, but I wonder how much a reduction would be achieved by angling the crewless area of the ship towards the solar wind (which I think Musk had touched on in an earlier talk).

Is any of that true? Are ideas really that easy? Also these people aren't being paid for ideas. They're being paid for vision and the ability to guide that vision through to completion.

I've met FAR more competent implementers in my life than I have product owners. You seem (and others) seem to be arguing that there is some sort of market inefficiency here, but I don't see that.

Tesla Is 'Structurally Unprofitable,' Chanos Says
Well, probably still beats growing up with fairy tails where giants eat children or where 2 children eat from a candy house and 1 ends up feeding the other until he is fat enough to be eaten by the witch. Or that nice one I heard at school where a woman turns into a salt pillar because god told her not to look backwards at the collapsing Sodom en Gomorra. And afterwards the two children that did survive get their dad drunk and have sex. Ok, I only heard that last part later.

You know, children hear stories from a wide variety of sources and they have parents to help interpret them and give them a place in their world view. Children ask questions to tweak this view and I don't think we should be to whiny about stories that don't seem to hit the exact educational, politically correct, wholesome, inclusive tone that you had in mind when your kid was born.

There was a heated discussion just the other day:

Never read the book (been meaning to!) but thought their cinematography was solid, and that the supporting cast puts on a strong performance. Agreed though that the protagonists' arcs are very cliche and flat.
His presentation style usually seems to be pretty raw, in a good way. It's not as crisp/polished as Jobs' presentations were, or in fact others.

As in, it's not as marketable. It's doesn't seem like it's been a style of preparation for a pure sales/marketing kind of pitch.

Kind of interesting, in my opinion.
Extrapolating very naively from SpaceX prices[1] for Falcon Heavy to low earth orbit suggests a ticket price of about $150,000, at $1500 per kg

That is ignoring safety, and other pros and cons such as Falcon Heavy didn't fly yet, Space-X doesn't have a passenger module, frequency and economic scale of passenger operation, different flight profile from LEO, lack of regulatory framework, and so on

I think it's weighing on him.. I think he'd like to move/iterate faster.. and the costs/stress of doing what he's doing when MANY keep saying 'Can't BE DONE' ... well.. to persevere through that.. takes some real strength of character and determination...but it's still stressful. I think you can hear that in his voice. I bet he's tired as fuck.
I am not sure how common that is, though. I am a native speaker and have not heard that expression before.
Man, that made me realize that black holes really are literally "holes".
I trust SpaceX to figure this out.

They've already solved the hardest problem: landing a rocket upright

Off-Topic: Most stories about politics, or crime, or sports, unless they're evidence of some interesting new phenomenon. Ideological or political battle or talking points. Videos of pratfalls or disasters, or cute animal pictures. If they'd cover it on TV news, it's probably off-topic."

This article is in line with "anything that gratifies one's intellectual curiosity".
Nitpick: We're extremely open, ... compared to other COMPANY BACKED PROJECTS, but far away of totally OPENSOURCE projects that doesn't reserve any feature... we currently have...

https://www.haproxy.com/products/haproxy-community-vs-enterp...

Said that. Yes I'm grateful to be able to run and modify both HAproxy and Nginx for free, but parent is totally right in the comment. Both projects are going that route, compared with their beginnings.
Simply put, they can command it. US GDP per capita is ~1/3 higher than in Germany, as is the median income. It's why companies like Softlayer or Rackspace, with relatively high prices, built such substantial businesses in the dedicated space years ago: US businesses could afford it.

The underlying cost structure is also more challenging in the US for most dedicated hosts. Building a data center in the US, as with most infrastructure, costs more than it does in Germany.

When you account for the higher cost of infrastructure and the higher productivity (economic output), a $80 Hetzner server becomes a $120 or $140 server in the US.

It's the same reason housing in Australia is so expensive (their incomes have skyrocketed over the last 15 years), or why the cost of living is so high in Switzerland (very high incomes). If you cut US GDP per capita from ~$57k-$60k down to $28,000 (just as an example) - dedicated hosts in the US would not be able to command the same high prices, the market would not bear that.
The Carbon network has high quality, relevant ads for developers. You might want to look into it.

Well, nignx inc does first develop their proprietary software... Then, they "open" some features.
With nginx plus, you're locked to nginx, like when you were using a F5 load-balancer!

HAProxy Technologies pushes first its developments in the -dev community branch. Check the commits for the feature given above (SRV records, non exhaustive list of patches):
http://git.haproxy.org/?p=haproxy.git&a=search&h=HEAD&st=com...

HAProxy technologies simply makes the effort of maintaining a branch of HAProxy in which some -dev features are backported. That way, users of HAProxy Enterprise have the most stable and feature reach version of HAProxy.
And as Willy stated, every user of HAProxy Enterprise also have access to the source packages.

So from a business point of view, the main difference between HAProxy and nginx is that HAProxy is the respects both its community and customers.
And that's at the heart of all these problems. People are vicious, especially when they're in large groups making decisions that they don't need to feel even remotely accountable for. Oddly enough, I'm not trying to make a small-government or anti-democracy point in general: this is probably the least vicious we as a species have managed to make ourselves behave.
Abstractly, very much yes.

In the context of nano and editors, you also have to contend with POSIX, tty I/O, etc.

> I'm a big fan of pushpin.

Always good to hear. :)

> Btw appbase is a pushpin user right?

Yup.

> The pricing page is confusing.

The paid plan doesn't come with any bundled minutes/messages, however we're considering changing this (e.g. up to 50,000 minutes/messages, then pure-usage cost above that).

It would be nice if we could abstract away the three metrics and only bill for a single metric, but I don't think it's economically workable. In practice, we pay a cost for all three, and they vary wildly by customer. Competitors generally account for all these metrics too (not an excuse, but...).

I do agree the pricing page could be more clear though. Even the current pricing is sometimes misinterpreted.

> On-premise option should have transparent pricing

I rarely see this elsewhere, but I can imagine how it may reduce friction. Worth considering.

> I think focusing on public cloud offering like mlab is the way to go

Thanks for the tip.

> I've seen too many people suffer from the false economy of used cars

Just get a 1-2 year old low-mileage CPO vehicle. It should still have the original warranty active. Ideally you should also target brands with great warranties like Hyundai (100k miles/10 years). This is as far as I can tell close to the optimal financial strategy for car ownership.

Personally, though, I do buy new, and I pay cash so I never, ever have a car payment. I hate the feeling of paying off a car over years as it depreciates. I really prefer to just get it over with and then enjoy knowing that I totally own it, no strings attached.
Amazon is "currently in preproduction, production or post on 67 TV series and 20 movies around the world." That's more than the old networks.

So finally, a video version of "Snow Crash". That should be fun. Bringing the scope of Ringworld to the screen will be very tough. Good that they're trying.

Finally, we're getting past Star [Trek|Wars|Gate|Craft] and the Marvel Recycled Universe, into better SF.
I can't help but feel this is a shortcoming of some of the other apps you are naming. In particular, if they played well with $EDITOR then this wouldn't be an issue.

Instead, everyone almost always finds their own way of rendering the text editor portion of what they are doing. Consider, your concern could just as easily be shifted to complaining about IntelliJ. Why can't I easily call out to it to get the information it knows?

I'd praise vim as a 15+year vim user, but people crap on nano without even knowing the shortcuts it provides (cut/paste/move rows, justify a block of text, etc.) which are very useful when remote editing configuration files. Never in my life have I remotely opened a config with nano and thought to myself "oh damn I wish it was vi".
The massive and well-funded propaganda effort to destroy unions at all costs has been extremely successful, as we can see from your post.

I have never heard of, read, talked to, or even imagined that any living person would consider contributing to open source to be "depriving a union worker of their wages" or "scabbing". Have you ever even heard of an actual existing union before? Have you ever known someone who has participated in (well, let's be generous: imagined) a strike? Has any union ever banned its members from donating their free time to charity? Are you listening to yourself?
Fuel cost is a constant for rocketry, there is nothing to figure out there, and people tend to go through a whole bunch of checks before they are allowed to be flown on a rocket to stop them from developing some critical issue in a place where there is no way to get help or be helped. You can't do emergency medical stuff while accelerating and decelerating in a rocket and this one is doing either one almost all the time.
i don't quite follow what you're trying to say.
Hawaii Five-0 just got "whitewashed". Grace Park and Daniel Dae Kim were fired when they demanded pay parity with the two lead white guys.
> "After all, the main benefit of Smith retiring from Equifax, as opposed to being fired for cause—besides preserving his dignity—is that he'll get to continue earning his unvested stock compensation, including options and performance-based awards, as though he were still working at the company, according to Equifax policy. That perk, however, could still be revoked."

Generally when you leave a company your vesting stops. This is such a sweet deal, it's disgusting. They should have fired him for gross negligence and sue the lot of them.

(I know, they're probably thoroughly protected by corp vs individual status, layers of bureaucracy, etc, etc but it makes me feel good saying "sue the bastards!" so let me. ;) )
