At least in the US that is not possible anymore. The wild inconsistency (arbitrary enforcement) of Anti-Trust Law has been replaced by a consistent definition thanks to the activities of many judges and legal theorists. The new definition is basically that one needs to prove abuse of consumers to make Anti-Trust law effective.

I don't think SpaceX is in danger of being accused of that.

They really don't have any competition on price anymore, but they are yet unable to actually do as many flights as they need to. To solve that they are building even more launch sites and thanks to the re-usability they will be able to do more flights without further increasing their engine output.
Not disagreeing with your overall claim but it's worth pointing out that not all Hispanics in the US are descendants of immigrants (into the US).

New Mexico for instance still has families with large tracts of land granted by the Spanish Crown before the US even existed.

Materialism is not inescapable for atheists in philosophy at all. You can be anti-realist or an idealist sans God. You can also be a platonist. Or you could be a dualist like Chalmers. There's plenty of room for different views than materialism without committing to a belief in the supernatural.
How can one say an unavoidably subjective viewpoint is beyond doubt?

And this is not merely philosophical. The notion of improvement can be validly measured in many disciplines, and this is true in many disciplines that are under scrutiny for their lack of particular genitalia.
I got extremely worried when I saw that happen too. I didn't even think to look at the altitude indicator.
It looks like numeric is a decimal type. 1/7 can't be represented exactly in either binary or decimal, so it's going to come down to rounding. It just so happens that 1/7 in binary, rounded to float precision, then multiplied by 7, is equal to 1. Do the same in decimal with whatever precision numeric gives you, and the result is not 1. I don't think there's any deep reason for it, it's just how it happens to work out. You can probably find a value where the opposite is true.
And that's why all of these companies are going to go under: as soon as they start having to charge real prices, instead of the artificial, VC-funded promo prices, people bail. Because, whoa, food delivery is actually expensive.

Did none of these companies check, before moving in to "disrupt" the restaurant industry, that there was actually anything to disrupt? Restaraunts are not lazy incumbents growing fat on their unchallenged dominance: it's a cutthroat business. And their costs are almost entirely the food and the labor, which are, for all practical purposes, fixed. There are no margins to steal from here.
I've always pondered that I'd love to read in on these other fields, see what they find interesting and new.
Well, not understanding such topics deeply doesn't preclude one from appreciating the complexity. You can't expect everyone to be even interested in everything, but a little bit of intellectual curiosity, as a character trait - is that too much to dream of people?
Well, but then ISPs are honeypots too ;)
Great post however does anyone know how rate limiting specific users is typically implemented? For instance if you have a SaaS API with multiple subscription plans you generally rate limit users based on tier e.g free tier: up to X number of requests, paid tier: unlimited number of requests, etc. I am assuming this is typically handled in the API itself.

Thanks in advance.
All I was asserting was my original statement. Many drugs are on the market which are ineffective or harmful. As far as your conclusion there, like your other question it's dramatically over simplified. Whether it 'works' or not seems like a judgement so binary as to be useless. How well it works depends on many factors that we haven't discussed at all.

If you don't see the problems that Islamic fundamentalism is causing in Sweden and Germany, you are willfully ignorant. The way Islam is practiced in most of the world is incompatible with western democracy. It's anti-woman, anti-gay, and anti-human rights in general. And each successive generation tends to assimilate LESS rather than more. Yet the left and so-called feminists celebrate this fundamentalist religion for political expediency.

Yet. As far as I know, the plan is to create some generators and a basic colony that can terraform the land to try and create an atmosphere on the planet. It's not unlike what they were planning in "Total Recall" but, at least in this case, there's more science to it than fantasy.
Something to do, lol... I "need" to move 2 sites from a host to AWS and while I have a general idea of how AWS works and how to use it, I figured what better way to learn it quickly then to get certified for it.
They are pretty objective, but you're right they are oriented around what's testable. This mostly is true in large intro classes -- specialized grad courses (well really qualifiers), advanced undergrad courses with 10 students, they're testing good work. But what's testable is generally straightforward and pretty easy. So if a student can't even do well on what's testable they don't have a prayer at moving farther than that. Excepting for students with special needs, learning disabilities, etc.

It's like if we wanted to test someone's ability to run a mile but had no way to measure time. We'd still test them to see if they could complete it, and if they can't, well they certainly can't do it quickly. But anyone competent can most certainly pass that basic test.

Grades aren't an opportunity to show off, they're an opportunity to express basic competence.
I don't work on phone software as was explained. And POSIX is still very widely used and important in many industries.

People have been attacking POSIX almost as long as C/C++. But unsurprisingly no one has put forward anything that could replace it.

Given the fact that you don't seem to care that the OS or system libraries are written in C/C++. And you don't care that there are industries that produce C/C++ software that have nothing to do with mobile and more closely resembles system programming. Who exactly is the internet safety strike force trying to evangelize? And more importantly why do you feel the need to lecture developers in other industries on what language they should use even tho you have no experience or stake in those industries?

It just annoys people and makes them less likely to try the new meme language. And makes the internet safety strike force look like armatures with to much time on there hands.

You don't see C/C++ programmers running around the internet brigading functional programming languages with nonsense. Even tho most of those languages are total crap. Maybe we are to busy trying to write software. Maybe that's why everything is written in C/C++?

this is a really important point.

programs are self-contained entities, whereas prose often drags in multitudes of real-world context involving assumptions, motives, and other considerations.

a diff might inform you of an edit in chapter 2 where you changed a man's status from "divorced" to "widowed" (to make him appear more sympathetic), but it won't also remind you that you need to rewrite that section in chapter 25 where the man gets a phone-call from his former wife.

this type of thing happens a lot, in ways that are much more subtle than that silly example. and it's usually because the arc of the story is greater than (and different from) a simple sum of its pieces.

"When the last man who remembers the horrors of the last great war dies, the next great war becomes inevitable."

The human race is like a giant fuzzing machine, we just try everything, push every boundary, bad and good, and see what happens.

But, our lives are too short for the lessons to last very long, and we repeat our mistakes relatively frequently. We try to encode some of the lessons into social structures, from religion to literature to law, to pass onto future generations.

But I can't help but wonder how things would be in this regard if we all just lived an order of magnitude longer. Less war? Fewer financial collapses?

I also wonder if less innovation too, but I imagine if the great inventors of our time lived 10x longer we'd get more rather than less, given that it takes an increasingly large portion of a lifetime to learn enough of our growing body of scientific knowledge to be able to make real contributions to it.

It really comes down to objectivity vs subjectivity. What properties are objective features of the world, if any, and which ones are either individual or creature specific?

And if science is our best attempt at creating an objective account of the world, how do we include the subjectivity of creatures different than us in that account?

If we can't, then science is incomplete, because the world isn't entirely objective. Also, if the objective (shape, extension, number, etc) is created by abstracting away from the subjective (color, smell, feel, etc), then you can't use the objective to explain the subjective, although you can correlate the two (certain brain processes result in certain subjective experiences).

Alto: A personal computer (1979) [pdf]
Well no, you don't have to compare to the first thirty launches with those when we're talking about competition for launch services. Somebody choosing a launch provider for their satellite today doesn't care what the reliability of the Atlas was in the 1960s, they only care what it is today.

If I was arguing that "SpaceX sucks and they deserve to fail because they're so unreliable" then you'd have a point, but I'm not.

Good point. If you think about it, if everyone was responsible and stuff, these kinds of incidents could be avoided and the system would work so much better. I mean, I know that financially the host might be compensated but personally, the stress of having my home torn apart like that by strangers would be too much for me.

> That's mostly guessing, though, as I'm not a rocket scientist and can't find hard information on this.

Yeah, my understanding is that you're wrong on this, though I too am not a rocket scientist. But a few points:

> SpaceX has launched and landed about 10 of these rockets, and has so far reused one. That rocket was first used about a year ago.

While this is factually correct, extrapolating from this will not give any useful insight.

> the amount of effort needed to prepare a rocket for reuse relative to that needed to produce a new rocket

It may be somewhat counter-intuitive, but an already-flown rocket is easier to fly a second time than it is the first time: it's already been "flight-proven." For example, a lot of defects on a microscopic scale simply cannot be detected ahead of time, and the only way to truly detect them is to test the rocket. This is why there are static fires ahead of launch. And it is also why there is a lot of over-engineering (in many things, not just rockets, but airplanes etc.)

The important thing here is that they land the rocket without too many additional stresses. It's not like the Space Shuttle boosters which were dumped into the ocean and had to deal with a lot of refurbishment.

> if they were, I think they would have launched a used rocket earlier.

The first one will always take longer. They're also finalizing the design, and had an accident investigation last year that was a big burden.

> I understand the enthusiasm, but

I'm not sure you do, but I hope I may have convinced you otherwise ;) The answers to your questions could really be "close to 100%" and "a few weeks to months" (more optimistic people will say "days or hours" to that last question).

What they've managed today is a huge milestone, and they're iterating on an astonishing timeframe. They hadn't even landed a single rocket a few years ago, and that was the truly difficult part. It's incredible how fast their progress has been, especially in the context of the space industry generally.
This article kind of makes me glad we decided to build our SaaS API on top of AWS API Gateway. At least I don't have to worry about the fine details of implementing rate limiting - just outsource that hard stuff to AWS and tuck our actual API endpoint behind their gateway.
To be a bat, or a woman, or man, means to be an agent that exists as part of an environment, learning to select the best actions that maximize rewards.

Of course for a bat the list of possible sensations, actions and rewards is different than for men or women. But what doesn't change is that they are all agents acting by reinforcement learning, trying to survive.

I'm wondering why philosophy doesn't take this stance. Is it because it sounds too similar to behaviorism? Does it seem reductionist? Instead of using the parsimonious concept of reinforcement learning agent, they use hard to define words such as consciousness and self. Instead of looking at what matters - reward maximization, survival - they analyze qualia and Chinese Rooms.

Philosophers, why are you ignoring recent AI research? Isn't it a waste of time to use such intuitive concepts as consciousness, free will and self? If only you could have come to a definition of consciousness you agree upon, but you can't, because it's a reification, a suitcase concept.
Yes, and that's the problem. The US had welcomed them, because lots of dumb work needed doing. But now, not so much.

So how do societies deal with them? People with no prospects, especially young men, are dangerous.

I do not think he makes this statement. He seems perfectly open to the possibility of explaining subjective experiences in physical terms but he is convinced that we are at least very far away from being able to do it. In consequence he obviously considers all current attempts flawed and lacking.
Datacenter cooling can be problematic in unexpected ways: NASA's Mission Control datacenter at the Johnson Space Center was an interesting beast - designed for the IBM vacuum tube behemoths of the 1960s, it was both huge in acreage (only a small corner was used by the '90s) as well as arctic in it's cooling capacity (since every tube literally had a heater in it!) In the mid-to-late '90s, working at Sun, I put in the first ATM and Fibre Channel networks in there, the latter initially connecting up a bunch of the new SPARCstorage arrays (30 individual disks per array unit!) to the brand new UltraSPARC servers.

As I hinted earlier, the AC system was epic - literally cold enough to hang meat. It originally used several chillers, but even after turning off all but one, it was still FREEZING (well, nearly) in there - there was literally a rack of parkas hanging at the entrance, and you put one on if you were staying more than a couple of minutes.

Not long after the system went in, we got a call from their admins saying there was something wrong with the network, as they couldn't get the Storage Arrays back up - sometimes. Eventually, a pattern emerged: the Arrays refused to restart after they had been shut down for more than an hour or two, but when we took them back to our office, they worked just fine. Turns out the problem was thermal: The room was so cold that the new state-of-the-art HDDs literally didn't have the torque to spin the platters up again against the cold-shrunk tolerances. We checked with Seagate and they said NASA was operating the disks well below their design temperature - they had never expected anyone to do that! The fix: 1) Don't shut the array down for too long, and, 2) if you really have to shut it down longer you'll have to wrap the whole array in plastic to prevent condensation, then take it outside to let the disks warm up enough before bringing it back into the DC and spinning up before the disks almost literally froze up again! This was, of course, duly written up in an official NASA policy and procedures manual. I suppose SSDs were a big win for NASA, as I expect the problem only got worse with succeeding generations of spinning drives....

The way I think about this is: if not SpaceX, some govt or company will one day establish a base on another planet. Something like the stations we have in Antarctica. So SpaceX taking a shot at this isn't totally absurd - over-ambitious, sure, but not so ridiculous as to be out of the question. Maybe it won't happen for a few decades, or a century - but IMO it's very likely it will happen some time. And that's what ultimately matters. It doesn't have to be Elon Musk's company that does it.

Cities on Mars - it's not productive debating this at such an early stage, though it makes for an interesting discussion.
>i don't think i agree. i think they're moving up the chain to plug weaknesses in their model.

Moving up the chain doesn't plug weaknesses. It dilutes your focus and increases the number of competitors gunning for you.

The single worst business decision that Larry Ellison made was to acquire SAP. He looked at SAP's product, building on top of Oracle's databases, and thought, "Hey, that's value I can capture." The effect of that acquisition was to dilute Oracle's focus on its core product, which, in the long run, probably hurt Oracle more than its acquisition of SAP helped.

I'm ok with aiming high and en-passant solving cheap access to orbit. Anything else is gravy, imagine if that dream did not exist this whole saga would not have happened.

Dreams are good, they allow people to expend energy chasing that dream and the spin-offs from that may be worth as much or more to humanity than the original dream, even if we may not be able to figure out what path that might take today.

I'm certainly not complaining, hope they dream a lot more and will produce many more useful milestones, and if they don't end up achieving their dream I'll feel sorry for them but thank them for their incredible service anyway.

Think of that dream as a very powerful motivator for a lot of extremely smart and talented people. It's the fox to a whole pack of hounds that would very much like to gain ground and as such it seems to be doing a very good job.
