Okay cool. So no matter who the mark is (an elderly person, or a child) you can just take them for a ride if you're honest and she finds that moral. Btw in your example, in order to make a profit the shares must have been worth more than $2X in reality so the person lied and they didn't check the lie.

But what part of her philosophy says you must be honest in everything? Selfishness may entail lying, especially in sales (if you don't at the least creatively omit things, someone else who does will eat your lunch).

In addition, if you didn't promise anything, you can go ahead an just steal or screw everyone as long as you don't get caught. Check out example #1 and #2 and tell me where Ayn Rand's theory says you can't do that:

Corporate income taxes by state would seem to deny a race to the bottom. Very few (6?) have no corporate income tax and not all business are located in those states.

While states like business there, they also like taxes. Not allowing them to tax out of state sales would seem to be a good brake on their greed.
Z3 is an SMT solver, which means it combines a boolean SAT solver, which is used to solve the boolean structure of the problem, with theory-specific solvers, e.g. bit vectors, or linear equations.

Modern SAT solvers use the DPLL algorithm, which has in turn influenced modern CSP solvers. Wikipedia has a great page on DPLL:

Oops, you're right. I was confusing the proposal with how it works in Elixir.

I really like the partial application example from your source:

let newScore = person.score
|> double
|> add(7, ?)
|> boundScore(0, 100, ?);

Partial application is a separate stage 1 proposal but together with the pipe operator I really prefer this:

let x = 2
|> Math.pow(5, ?)
|> square

to this:

let x = pipe(2, $ => Math.pow(5, $), square)

Probably no-one has ever thought that everyone enjoys exactly the same things. It's like if you're arguing with someone and the other person says "2+2=4" apparently to support their argument, it would just make you wonder what their argument is, that they bring in 2+2=4 as supporting evidence. It's still puzzling why bring that in, but it seems you have an unusual idea of subjective/objective, as the other commenter has pointed out. But I don't think that's the main issue here..

Trying to understand how people can say "there's nothing good/positive about smoking" :

It seems that - as very often happens in philosophy - there is an equivocation[0].

In one sense, the statement is false (the one I hear, and the guy who said it's a silly thing to say):

There's absolutely nothing positive about smoking (including the smoker's pleasure)

and the other is true but trivial (the one you said you meant when you clarified) :

There's absolutely nothing positive about smoking (not including the smoker's pleasure)

- apart from the smoker's enjoyment, there's nothing good about smoking. But (like ice cream) what are these other good things supposed to be? They are done for enjoyment.

You (and Crockford in that video) say it like it's a hard-hitting substantive thing to say, bemused at how it's not generally admitted. I think it seems so because of this equivocation.

As far as books go; K&R contains a lot of wisdom despite it's apparent simplicity; and the language hasn't really changed that much since last edition. But to answer some of your questions:

CMake is by far the most convenient build tool I've come across for C so far, the link below will give you an idea of how it looks. I find linters mostly a waste of time , but I run all my tests through valgrind before committing; I don't miss programming in C without valgrind at all; it's also an excellent profiler in combination with KCacheGrind. For testing, simple functions and bit of macro magic on top goes pretty far; C programmers tend to value simplicity, you won't find that many epic unit testing adventure frameworks out there. clang or gcc doesn't really matter, I prefer clang's error messages; and both support GNU extensions, which solve most of the boring problems with coding in C.

> The metro, which was named after Vladimir Ilyich Lenin

OK, I'm nitpicking, but it's not exactly true.

The construction was overseen by the ruthless Kaganovich and named after him. When Kaganovich was purged by the successor of Stalin (http://soviethistory.msu.edu/1934-2/the-moscow-metro/), it was changed to "Lenin's".
> Is copper latency really equivalent to fiber?

Notwithstanding differences between specific types of cables and transceivers, yes, the rule of thumb is that they're roughly equivalent. The big advantages with fiber mostly come with being physically smaller for a given bandwidth (e.g. more bandwidth per square inch of conduit cross-section, more bandwidth per cable weight for vertical or suspended runs) and needing less active equipment between any two points in the network (e.g. PON, long-haul single-mode runs).

Controlling Android Auto and CarPlay with car controls is like operating a home theatre with a Logitech remote: it's great if you remember how third-party physical buttons map to the software.

The superiority of iDrive isn't readily apparent until you live with it for a few weeks and you realise how straightforward the controls are for frequent tasks, and how the quick-access buttons can turn complex UI dives into one-button macros.

I love having physical buttons for "drive home", for "open my GPS address book" button, for "stop nagivating", for "call my wife", for "show trip data" and "show program details for the current DAB radio station".
Solar flare particles (unlike cosmic rays) are rather low energy, so it doesn’t take much to shield from them. I believe the surface of Mars is reasonably safe due to its atmosphere. Even at 0.007 atm, the total mass of air between you and the sun is quite large.

Solar flare particles would be an issue on the journey to Mars, however.

For cosmic rays, the exposure on Mars is the same as on the ISS: half that of deep space (the other half blocked by the planet below you). But so far there hasn’t been an elevated cancer rate for ISS astronauts, many of whom have spent 6+ months there.
What about a potential quantum link.

Quantum is currently talked about a lot in relation to computer processing, but I actually got interested into quantum physics over a decade ago through scientfic work being done with a goal off pseudo-teleportation.

They experimented with the vibrating? particles in such a way, that they would "resonate" particles an x distance away, potentially even making distance irrelevant. All happening at a 1:1 ratio.

I belive it's called quantum entanglement

It's only a matter of time before Intel makes a huge chip acquisition, possibly of AMD itself to compete with Nvidia. I think they could now make the case that this wouldn't be an anti-trust issue because...there are more competition than ever in the space now. AMD is small potatoes compared to Nvidia, Qualcomm, etc. I am fairly certain that MacOS will eventually be switched to ARM, as they begin to merge MacOS and iOS but in an effort to avoid what Microsoft has encountered in developing for ARM and x86.

You really want to buy a card a miner has pushed hard for weeks and months on end with who-knows-what cooling?
(I'm making the same distinction between exact and modified copies that the Creative Commons folks make...)

As to your second point... Ha! Fair enough. But IIRC case law has actually recognized that the copies created on a computer as you install and execute a program count as "copies" for the purpose of needing a license for an activity that would otherwise violate copyright. That is why EULAs are, to some extent, considered valid and enforceable. No such case has been made for your retinas encoding the light bouncing off a page and transferring that pattern to your neurons.

So yeah, they're marking everything up to double MSRP basically.
I’m not sure I’d want a card that’s been at full utilization, 24 hours a day, for who knows how long.
Bought some cards during the Christmas break season and prices/availability were fine. I was surprised when I went to buy some more and saw the prices! I reason that if crypto currenices crash I can re-purpose my nice new collection of GPU's to do Deep Learning training. It's got me pondering how one could do a distributed deep-learning training as the proof-of-work for a crypto-currency. Then the POW would be doing useful work anyways!

Along with causing issues with GPU card supplies there's been a lot of articles talking about how crypto-mining wastes electricity and hurts the environment. That's not necessarily the case across the board. Instead of running an electric heater this winter I am running a few GPU miners which produce a decent amount of heat. That helps me get a two-for-one benefit for ~9 months of the year since it's relatively chilly here year around. Might not work in all climates, but in many places its nice way to produce heat that'd just be waste heat anyways.

I'm legitimately worried about the long term future of my hobby (PC gaming) at this point.

Prices like this have a cascade effect because when less people can afford to build a PC and/or upgrade there's less incentive for developers and publishers to spend time on the platform. Consoles are shielded by the ability of Sony and Microsoft to take losses which will be absorbed by online fees and higher game prices but no such cushion exists for PCs (this is a strength to be sure, but a double edged sword in this respect).

PC gamers have spent years disproving the image of PCs as prohibitively expensive and now it's coming crashing down due to people in a faux gold rush wasting hardware and energy. I wish it would stop, but I don't know how much of the damage to the hobby can be repaired.

Of course there are other factors. Machine learning is eating up cards, smartphones and tablets are eating RAM, and I don't doubt there's price fixing. But ML is at least useful to humanity (sometimes), smartphones and tablets are tangible products, and price fixing can be investigated and punished.

I'm relatively shielded from this as I just built a high end machine (i7-7700, 1080ti, 32GB DDR4) that will last a while but the next time I want to build a machine might be painful. While I would probably pay the price, others will not, and the hobby will suffer.

ASICs aren't saving the planet either - people are incentivized to burn up to $BLOCK_REWARD of electricity per block, the number of hashes it takes to do so is irrelevant. If you come up with a better ASIC, people will buy more of them, the network difficulty increases, and you're back where you started. It's just another stage in the Red Queen's Race.

The only thing ASICs do is centralize control (because economies of scale favor companies who can produce+operate their own chips). Full stop.

Proof of stake doesn't actually work either, or at least not without a centralized master key to prevent stake grinding/rewriting history (at which point why have staking in the first place). And in many cases, it may devolve to proof of work anyway.

There is no efficient cryptocurrency, and the cat's out of the bag now, there is nothing that can (practically) be done to stop it. Apart from charging people exponentially-increasing rates on their utility bills, that is, but China isn't going to do that, so the planet is just going to have to take another one for the team.

I imagine they are also shielded to some extent by being AMD APU-based, so the market for discrete GPUs has less of an effect.

Some cryptocurrencies are mined using only ASICs and others are mined using only GPUs (because there aren't any ASICs for those algorithms).

My employer recently required that any mobile access (or, really, any access through a method other than web browser) to any real-time communications systems for the company, including internal e-mail and instant messaging, must be through a device that has the chosen MDM solution enabled.

It was at that point that I informed my manager that I would no longer be checking work e-mail and instant messages on my mobile device unless the company chose to pay for a company-owned device and require that I carry it. My manager told me that he intended to do the exact same thing. Informal surveys of my group show that about 80% of the group are not following work e-mail or IMs when away from work computers.

I am happy that this is the case but am also disappointed that the remaining 20% are almost entirely the "burn the candle at both ends" segment of our group and they're forever replying to threads and the like even when off work on weekend or vacation.

I have read on multiple places that MDMs on an iPhone have quite restricted access (no SMS/iMessage, pictures, non-MDM e-mail, and the like) unless the device has been wiped and redone under the All Powerful MDM mode but I don't know if those people are correct or if they're all going from the same (possibly inaccurate) source. Therefore, I keep the MDM stuff off of my iPhone because it is mine and I have data from other unrelated projects and companies on it that is none of my employer's business nor theirs to have access to hoover up.

Gamers are complaining about why can't nVidia just ramp up their production.

Having worked in a Fab and an assembly factory, there is a tremendous amount of coordination that needs to happen. Let's forget the business aspects for a moment - in order to ramp up production, it is not just building more lines. Silicon industry supply chains are mind bogglingly complex from oil-free-air supply hardware, etching chemicals supplier, automation equipment all the way to the copper mine. All of these interdependent supply chains have to scale in perfect coordination without an exception to be able to scale production.

Then there is the business side - building more lines could be foolish investment if the LRP (long range projections) is weak.

nVidia fabs their chips at TSMC. Say, TSMC has wafers ready but the assembly houses are struggling to keep up - the entire supply chain is broken and demand cannot be met.
