> Why are you saying that the universe might not exist if it were not for humans.

I didn't say that. I said there is no difference between a universe not existing, and one that has no one who notices that it exists.

Re: 1 and 2 I said "(or another sentients)".

3: I guess you are implying someone made the universe and is running it? In that case, they are the ones aware of it, so that counts.

4: Hu?? What are dark matter entities? We notice the universe and care that it exists. That's enough. The specific level of intelligence, (or aggression for that matter) does not matter.

> Again, the universe doesn't care.

That's the point. WE care, and we are the ones that give the universe a "voice" as you will. We speak for it, we do the "caring" for it. Without us (or other sentients) it might as well not not exist.

> Humans are just a blip among much larger things that are happening in the universe.

Just because someone is big doesn't make it important. Importance comes from meaning. A really big explosion in space, that does noting at all, is completely unimportant. While a tiny little seed that someone wanted to plant matters a lot.
Didn't really get some of that. I guess I need to brush up on my economics terms and concepts.

I don't think that presumption is true, it's a high bar that doesn't really provide much benefit to achieve. If a computer decides to tap the brakes because it thinks an "oh shit" scenario is coming up, why is that suddenly a huge transgression?

sp527 covered it pretty well, but it's a really good class. While you could just read the instructor's book, A Mind for Numbers, this does a good job with the motivational aspect.

It even comes with interviews from some successful scientists on the tips they use.
I was confused as well. I don't recall seeing this the first time I read the article, but on the second time through, they include this:
"Our research reveals that Plimpton 322 describes the shapes of right-angle triangles using a novel kind of trigonometry based on ratios, not angles and circles. It is a fascinating mathematical work that demonstrates undoubted genius."
Which is probably where the "more accurate" statement comes from.
Publish the source code files only under GPL and Linux kernel developers will be happy.

You might get intro trouble with the ZFS side however, since the CDDL license says: "must also be made available in Source Code form and that Source Code form must be distributed only under the terms of this License".

If the Source Code form is only under the terms of the GPL, then the above condition is not met. The law suit would thus come from the ZFS side.

Yea didn't phrase that correctly. What I really meant was it's largely the standard stuff you come across if you spend a handful of hours browsing on the subject.

The 4004 is not an ancestor of x86 even though the part numbers make it seem so. The 4004 was s 4-bit processor designed for calculators, and is different from x86 in almost every way. The 4004 isn't even a von Neumann architecture; it has separate data and instruction memory. The 4004 has weird instructions like KBP (Keyboard Process) to decode a calculator keyboard. I/O is done through RAM ports , not memory-mapped I/O, but I/O ports built into the RAM chips!

The origin of x86 is the Datapoint 2200, a desktop computer built from TTL chips. Datapoint contracted Intel to build a single-chip version of the 2200's processor, and Intel built the 8008, which was essentially a clone. Datapoint decided not to use the chip and gave the rights to Intel and the rest is history. Intel improved the 8008 to get the popular 8080 microprocessor. Intel then created the 8086, which was a 16-bit processor loosely based on the 8080. From that, the x86 architecture developed. Many features of x86 can be mapped back to the Datapoint 2200, such as little-endian.
Whole Foods is the only place I've ever returned food. Once, I returned some clams and muscles, because when I got home, it was obvious they were bad. I also returned some produce that literally wasn't eatable the next day.
I didn't say I never saw a rear-end accident, I said I never saw three in a single commute and am not sure whether I saw two in a single commute.

The guy I was replying to said that he saw at least 2 every commute, often more. (Edit: Actually, sorry, 2 every day, not every commute).
I have mixed feelings about this one. It certainly has inspired some interesting discussion. The paper itself is obtuse and difficult to absorb.

The methodology isn't _really_ new, but it isn't used frequently. While they showed it as competitive to commonly used sorting algorithms, situationally it can really shine and show significant performance benefits. I'm surprised they didn't show this in one of the graphs (or I missed it in my brief speed-thru).

I don't really see a future for this in standard libraries. I can totally see this methodology being used in the wild in a variety of systems where time = money or entities are looking for a small proprietary distinguishing edge.
It is a bit excessive to say that it is unrelated. Many of the techniques and methologies created for the 4004 were instrumental in the development the 8008. Also, the 4004, 8008, and 8080 were all designed by more or less the same people (esp. Faggin).

The point is that computers don't really have the same type of reflexes that humans have. The theory is that everything is pretty fast. (OK, they can run a background analysis in the cloud but that's presumably too slow to be useful.) Computers are generally not going to respond with "reflexes" and then change they're minds once they've had time to think about it for half a second.

Computers could possibly be designed with these sorts of decision making patterns if there were a need to but I'm not aware of that being done today.
I took the course. I love learning and have been learning new things for decades and thought my techniques were pretty good. I'm a very fast learner. The course helped me more than I was expecting and my learning speed and ability to memorize noticeably improved. Especially with the foreign language I'm studying. And the theories around how the brain works were interesting. You're probably being a little cynical. ;-)
I'm not complaining, I'm asking the HN community, what does everyone else think? Perhaps I'm the only one who thinks it's an issue. But what if I'm not the only one? Would it warrant some change in guidelines in this case?
If command lines were built in systems designed around this principle, they would work slightly different than what we're used to. For instance, when invoking this 'program' on the command line, the system would discover it needs an image and use the command line itself to ask for an image from the user.

Alternatively there could be standard way to pass an image (or any other input) to a program - similar to a command line arg in current systems, for instance.
Thanks for answering. I guess I didn't mean my question to come off as a condescending or rhetorical question. I was hoping he had redeeming qualities. But getting high on PCP and busting up people's cars and getting into rows with the police is still pretty anti-social behavior.

However, you might use a space elevator at L1 or L2 (or both) that allow capture of HEO or launch or inter-system vehicles with only efficient high impulse rocket motors.

Note that you could use Spectra/Kevlar or other common high strength materials with a taper ratio of only 4:1 with a lunar elevator. It might take "only" ~50 tons of spectra to hang the weight and allow lifts of a 1000kg or so... its much more doable than earth or mars.

If you just wanted the information, you could stick with the book since it goes into greater depth about the learning method.

The one thing I really like about the course were the interviews where the interviewees (such as Cal Newport and the 1 year MIT degree guy) went into great depth on their focus methods.

I also liked the assignments since the scorers gave helpful feedback although I don't know what it's like now with the changes coursera has gone through since I took this class.

the guidelines say it's okay IF there's a workaround. if there's a workaround then it meets your requirement of "can be opened without registering".
Books and papers are passive - they don't have an agenda (beyond what's in the printed content anyway, but you'd generally have an idea about that beforehand).

Digital devices on the other hand push their own agenda - driving engagement, registering ad impressions, and are designed to keep you hooked and coming back - because that's what's profitable.

Being in control (with passive reading material) vs not being in control (with digital devices, unless you're extraordinarily focussed) is the point of contention, at least the way I see it.
For what it's worth, they absolutely can cut their prices and continue to keep the current level of quality simply because amazons investors care far less about profits than whole foods former investors did.

In Q3 whole foods made 3,725 with a gross profit of 1,268 representing a profit margin of 34% and their current P/E ratio is around 35, Amazon for context has a P/E ratio of 240 at time of writing.

This means, that amazon can reduce the price of food by quite a bit and keep their investors happy. Amazon, based on the comparison between the two companies P/E ratio, can cut that profit margin by a factor of 7, meaning whole foods fits perfectly within amazon's model (unless they were to direct profits elsewhere), with the ability to reduce their prices there by 25% on average (representing a billion of dollars returned to consumers).

However, with such a price reduction, it's very possible that whole foods could become a mass market grocery store, while keeping it's current brand prestige. Additionally according to http://www.businessinsider.com/how-much-more-expensive-is-wh... the prices are really only 15% more than normal grocery stores, so amazon can choose to keep even more of the profit that they could afford to return to their customers (by investment standards) while also still undercutting the competition.
Trailers are vastly cheaper than the truck. I think it is insolveable to depend on battery loaded trailers. You lose so much flexibility with such a setup. Much better to keep the battery in the truck.
Yes, I do think that. It was a promotional piece for his SaaS.
Ill take a crack at this though I'm going to paraphrase and ignore thousands of small details but here was my experience:

At the time we were making 40k we only had one product. As such, growth could only come from either:
a) winning new clients with the service we had as is ("sell what you have to more people")
b) adding new functionality we knew our clients would be willing to pay more for ("figure out a way to upsell what you currently have") or
C) create a new service altogether that you could cross sell ("find something else to sell them")

We did a combination of a and c.

Strategy A is clear-cut. If you want to make more money go find more people to buy what you have. Of course, this is easier said than done. Is your solution any good? Is the problem worth solving? Is the lifetime customer value sufficiently higher than your customer acqusition cost? All of these things play a roll here. For us, I think all of the above were true. Our biggest challenge is we sell to enterprise and financial services at that which requires a robust outbound sales process (in other words, no one is going to sign up for our tools because of a twitter post or mention in a news paper). The key takeaway about this is that to grow a SAAS solution, you need to be thinking about how you are going to sell it from day one. Internally we are constantly asking ourselves "how do we merchandise this?" (I realize that is not the best word but it captures a lot of things you need to be thinking about). We don't initiate development of any feature or product without seriously considering and designing a sales strategy around it.

Strategy C (cross sell) is worth highlighting here. I believe people mentally don't like paying more for the same service once they have been anchored to a price point regardless of how much value they get from it. As such, I spend a lot of my time pondering services or tools that I can cross sell. People like vendor consolidation and once they know like and trust you it's easy to get them to open up about other solutions. Because they are distinct solutions you can start the pricing discussion from scratch and command higher fees. Another huge benefit is bundling always improves attrition and can become a major barrier to entry to the extent you are in a competitive space.

That's not to say B isn't important, we are constantly innovating. I find pricing to be a bit more sticky in the SAAS space so improving a product is more about creating moats, reducing attrition, building brand etc.

Not sure this answer will help as there are a lot of "it depends on what you are doing for who imbedded in my answer".
> Computers are generally not going to respond with "reflexes" and then change they're minds once they've had time to think about it for half a second.

Well I disagree on this point, as that's essentially how regressions work, so indirectly how neural networks work. The data the car gets isn't available immediately, all that information it takes in in half a second is useful data that aids in classification and decision making.

Just as a quick example, take https://tenso.rs/demos/rock-paper-scissors/ and think of the classifier as "making a decision", and it switches its decision based on the most recent information.
Really though, their profit margins are like 34%, when compared to amazon whose margins are like 4% this is huge.
Barely influential within it either.

I'll report in too. I took the course and thought it was excellent. I love learning and have been learning new things for decades and thought my techniques were pretty good. I'm a very fast learner. The course helped me more than I was expecting and my learning speed and ability to memorize noticeably improved. Especially with the foreign language I'm studying. And the theories around how the brain works were interesting. And it's a pretty short course.
But it can also have the opposite effect: people get put off as they think the product is vaporware (rightfully).
I agree, the devil is going to be in the almost infinite edge cases, the visual negotiation that goes on between drivers at box junctions, dealing with bad or aggressive drivers who ignore right of way or tailgate, ethical decisions in all the “Kobiashi Maru” no-win situations (extreme weather, black ice, highway pile up, mechanical failures).

An advanced AI may well be able to identify whether an object coming towards the windscreen is a bird, bat, leaf or a rock, but what will its intuition be about how much of a problem it is likely to be? Should it swerve to avoid a raccoon and risk whiplash for passengers? Should it aim to avoid large insects if the owner is vegan?

Also, people are very used to mild lawbreaking. We expect a cab driver to double park and let us out the car if there are no available parking spaces, but would an AI be authorised to bend the law or would it have to find the nearest parking space, which may be 5 blocks away and could be taken by the time it gets there?

I suspect we will get autonomous drone-like flying cars long before we get full autonomy in city centres or rural areas, because flying through a mostly obstacle-free space with an ability to avoid collisions on 3 axis seems much more reachable?
> Well, this is Debian - they generally don't maintain the software

They definitely maintain software. There is a whole pile of packages that aren't maintained upstream any more that are still maintained in Debian, they write things like manual pages for commands that don't have then, they bash the build scripts into something that works on a whole pile of architectures the author never considers, they manage what is probably the worlds biggest issue track system, and then there is the security team producing patches for versions upstream no longer supports.

But probably it's just your wording. While they do maintain software, they are mostly concerned with packaging existing software, not writing new stuff.

I have head that moon dust is reputed to be a consideration, as it creates a type of environmental problem that would not be as extensive a problem on Mars. My understanding is that, due to a lack of fluid and chemical erosion, it tends to be extremely fine and abrasive, and it clings to everything due to static charge, making it hard to keep out of compartments and machinery.

They're both definitely too far for a rescue mission or evacuation that wasn't planned for in advance. In terms of the old eggs/basket metaphor, it becomes a question of whether you want to use half your straw to weave a second basket, just in case the first one breaks, or if you want to use all of the straw to make your one basket as strong, redundant, and well designed as possible.
