"they're just wiggling the electrons in your appliances back and forth"

Sorry for highjacking your comment, but are there any physicists here who can comment on whether this is accurate? More in particular, does electricity have mass? Is 'current' electrons moving across a wire, or wiggling without 'moving'?

I've asked this years ago on the physics stack exchange, but I never got an answer I actually understood. The context for my question was a legal paper I was reading whose core argument relied on 'current' having mass, or rather, the consumption of electrical energy requiring the transfer of mass, however small. Note that there is an important precedent in my jurisdiction (the Netherlands) that sort of assumed this back in the 1930's, but in this particular argument (on ownership of virtual goods, like a sword in World of Warcraft), the issue of the mass was even more pertinent.

(note that I'm not interested in debating whether that matters re: ownerships of virtual goods; in my legal context it does. And yes I have a law degree. I'm just putting this in because I've asked several times in several places over the years, and there are always people who like to go 'XY problem!' and then make ridiculously wrong pseudo-legal arguments.)
No, and I probably should write up an experience report. The short version is that ClojureScript is fantastic and I would never have been able to create PartsBox without it.

The long version is of course more nuanced :-) But there are surprisingly few downsides to using ClojureScript.
You are likely to loose your shirt short-selling coastal property. For short-selling to be profitable, what you are short-selling should decrease in value, and do so rather quickly. The reason is that in the mean time you are required to reimburse the person you're borrowing the asset from for the revenue he would have had, had he held on to it. In the case of property that is the rental revenue. Time works against you when short-selling.

Home prices in flood-prone areas are still rising (albeit slower than elsewhere) in the US [1]. At some point they will go down, but time your short-selling wrong, and you will loose money.

Indeed, I can imagine (and still grossly underestimate) how frantically busy you would be. All the best for your startup. As I said, it was just a friendly ribbing. Given our interactions on HN I have come to gauge your taste a bit, hence my recommendations.

Vapnik, V. N. (1998), Statistical Learning Theory is a tome. You probably would not have time to read this. I would say go with the other two books of his. They sort of summarize his body of early work. Again a lot of water has flown below the Vapnik bridge, but you will get a non-hyped view of what ML is about.

Kevin P. Murphy, Machine Learning: A Probabilistic Perspective is also a hefty read, but its a good source and quite complementary to Vapnik's treatise. Kevin Murphy's book is about how to tractably model joint distribution of a (mostly discrete) set of random variables and draw inferences from them. So this is about smart and efficient ways to marginalize and condition and compress.

This is also a great book. You will see a lot of KTC here but mostly within the framework of convexity and duality.

Actually, that latter is a trend to make things more compact. The engine compartment of my current car, which has the very requirement that you mention, has nowhere near the amount of extra unused volume as the engine compartment of the car that I was driving a couple of decades ago had, permitting access to many components without other components being in the way. The engine compartment is also, itself, smaller overall.

> Since you never can finish counting

You seem to have serious trouble wrapping your head around the concept of words having different meanings in a layman context and a technical context. Just because you can't "count" (in the counting-out-loud-on-your-fingers sense) the naturals doesn't mean they aren't countable in the rigorous, set-theoretic sense. Your entire argument basically boils down to "this word means something different from what I'm used to it meaning in daily conversation".

> I think the concept of infinity is a con that mathematicians have pulled on us (as there isn't an easy reality to map on to). I can understand arbitrarily big set; however, I never managed to make the jump from arbitrarily finite to infinity.

How narcissistic do you have to be to assume that an entire academic discipline must be wrong just because you can't personally grok it?

> I don't have to describe it, I can hand-wave it just as the way mathematicians hand-waved the infinity.

It isn't hand-waved at all. Just because you don't understand it doesn't mean it's not rigorous. Go read a set theory textbook or take a MOOC or something.
Fixed-length fields and records weren't all that long ago. Remember ISAM in QuickBASIC and VB for DOS?
Luckily, those aren't mutually exclusive choices. And climate change potentially causes wars as countries are strapped for resources, so acting to fix climate change is a twofer.

Also: you are understating the cost of climate change. These estimates are tricky to get right, but the IPCC estimates a ballpark figure of 1-4% of GDP for a 4 degrees C increase in global mean temperature. That puts the cost on the order of trillions per year, not in total.

There's a joke somewhere about rowing teams and how the US tried to improve performance by replacing all the rowers with rowing managers.

Almost all structure is organized into log n tree structures to manage complexity. There's limited room at the top. All advice that focuses driving towards these limited spots seem ill conceived to me. The overall goal should be to improve the overall wealth of each node. But when everyone is trying and training to be a leader, you end up with 99% rejects with strengths that actually hamper them to be productive because now they think they're too good for everything else.
Nobody is suggesting that climate change should be tackled by _only_ those who volunteer to help. We are saying climate change is _everyone's_ responsibility. There definitely needs to be legislation in place as an "incentive" for those who can't be bothered or simply don't care (businesses and individuals alike) but that doesn't absolve your own responsibility either.

The continuity of real numbers provides a clean theoretical basis for continuity of functions.

Exactly. Real numbers are an invention to make mathematics simpler and cleaner. If you don't have continuous reals, it takes extensive case analysis to prove relatively simple things for, say, a binary floating point representation. It's possible to do that; Boyer and Moore did work like that to formalize floating point and check its correctness. (That work was funded by AMD, after the famous Pentium divide bug.)

Newtonian mechanics assumed that the physical universe is described by real numbers. But today, it seems that time, length, and mass are all quantized. There's thus not a physical basis for the existence of reals.

Maybe reals should be viewed merely as a useful convenience for analysis, not some fundamental part of mathematics.

Is that a contractor doing 40+ hours a week, 45+ weeks a year for the same company? Or are you talking people doing shorter more targeted projects?
I've never seen contractors care less, there can be issues of not understanding the context which can affect their work or people's perception, and certainly employees can feel insecure with contractors. But the reality is that the game wouldn't ship without them, that's why they're there.
This is very heavily Leangains-influenced, no? Would be nice to credit that as a source, if so.

That's the entire premise of the discussion! What do you mean where did I get that from?

>Predictable accidents vs murder? What's the difference but personal liability?

One is tragic, the other unethical and tragic. This point is exactly where you wind up with "all good behavior is ultimately selfish anyway" - particularly when you write: "Isn't that just self concern? You can't be linked personally as the cause of negative consequence, so you want to remain divorced from it." Here, you represent doing the right thing as avoiding being linked personally, as if it's just a self-interested maneuver. You're literally, plain as day saying that ethics is merely self interest, hence "all good behavior is ultimately selfish anyway."

The example you wrote above about a girl being run over and nobody helping is completely a false analogy (and a car analogy, no less :)). The assumption from the start, which I made very clear, is that you can't help without hurting others. Saving the girl who was run over does not imperil anyone and is completely moot!

The points in your response have been tactical rather than open (e.g. forcing me to go back and re-state the basic premise, which you suddenly no longer acknowledge, forcing me to go back and prove that you actually made the claim about ethics being self-interested, even though you did so plainly) and I don't appreciate that. These tactics further my conviction that your position is unjustified and ultimately dangerous.

I've seen these flags mentioned before, for both VirtualBox and VMWare. And it's always without exception been in conjunction with trying to get OSX running in a VM on non-Apple hardware.

I'm pretty sure both VirtualBox and VMWare could create a Apple-friendly template with these settings already tweaked for what OSX expects. In fact it would be trivial.

But for some reason they haven't.

Considering how VMWare Workstation Pro actually supports running MacOS on Windows, but has the relevant config removed in production-builds (needing it to be hacked back in), I'm going to assume there's some kind of political pressure going on here. Maybe even from a certain Cupertino-based company, wanting to prevent the mainline virtualization providers from commodotizing their commodity, run of the mill, standard X86 PC operating system.

That's a shame, because if they didn't, it would certainly make it much easier for me to build a solid and reliable CI pipeline for our MacOS and iOS stuff.
good games never gets old. they will last throug many generations. technology might change though. but as a single developer its a huge step to hire someone.
I work in the games industry.
If a contractor works 80 hours a week, they can bill for 80 hours a week. If an employee works unpaid overtime then at least part of it is in hopes for a nice bonus once the game comes out(apart from you know, the satisfaction of working on a game). So in that way, an employee can do loads of extra work and if the game tanks they won't see any extra money.
Correct me if I'm wrong, but hasn't the murder and crime rate in NYC gone down precipitously since they've buffed up the police force?

Maybe there are other ways to mitigate the excessive force, but I would say that 3% body cams are a good start for a force of this magnitude. With enough bureaucratic inertia it'll reach 100% in a decade or more. Give it time. It's not a small force. And by the way, civilians can legally own guns. It's patently dangerous to be a police officer in America. Civilians should not own guns. The only people with guns should be the police and military. And that's that.

I can't speak about gaming but for more general contracting the multiplier is 1.75 - 2.5x of a normal employee's salary

There are a lot of reasons why employers hire contractors, some more valid than others.

In my limited experience, it's rarely worth it, mostly because the relevant processes are never in place to ensure that loads of knowledge doesn't walk away with the contractor at the end of the contract

edit:

Should clarify that I'm in the UK.
Because they can be hired and fired at will, while an employee(at least where I work) has to be given at least 3 months notice, a severance package mandated by law, and they can sue for unfair dismissal. Plus you have to pay healthcare, pension fund and other benefits, plus they are entitled to 25 days of paid holiday a year plus unlimited paid sick leave.
And finally, it's hard to find someone willing to become an employee for just 3-6 months required to finish a product. That's where contractors come in - they are much quicker to hire, they are much quicker to let go, and healtcare,pension, holidays is their responsibility. So to companies they can be worth the 5-10x what they would pay an employee for the same amount of work.

I solved that problem with a far simpler solution. I don't own a smartphone. I spend eight to ten hours watching a screen at work. Don't want to spend another five doing the same thing in my leisure. I also don't own any tablets, for the same reason, except a Kindle which I use every now and then in commuting. Most people I meet feel surprised when I tell them I don't have a smartphone especially considering that I'm a "computer guy". But the thing is I don't really need it. I can't do any productive work on it and even if I could I wouldn't want to. As for the PC, I'm also off any social network, excluding Hacker News which is addictive but at least I'm learning stuff so I don't consider it procrastination.

4 degrees C is an absolute upper bound in the temperature predictions. The kind of thing you'd get if the world attempted to explicitly maximize CO2 output, instead of only pretending to minimize.

And then imagine if they did that for the next 80 years.

We are not going to climate change tomorrow, but I'd be awfully surprised if we haven't made some very good progress in the next 2 decades.

Solar prices have something like 10 to 100X decreased over the last 20 years, and there really isn't that much further (comparatively!) to go before they reach grid parity.

What I am saying is, that there are a whole lot of reasons to be optimistic about the future, and that panic seems a litter premature. We are currently easily on track to solving it, solely through normal capitalistic efforts that have created the amazing technology breakthroughs that we've seen over the last 2 decades.
Fourier transform (any kind of transform, really) is at the same time so simple and so mind-boggling. The math to produce it just fits together super neatly: applying algebra principles (basis change, dot products, etc.) to functions, and seeing that it works really is a stunning achievement of mathematics.

I sometimes wonder if analysis could have been discovered the other way around, that functions could have first been described as a sum of harmonics, and that we would have stumbled upon "time-defined" functions as the inverse fourier of harmonics.

If you don't know about the FT, you should really dig into it. It's way simpler that number theory, cryptography or complexity theory, yet it is incredibly useful and frankly beautiful.

I believe he's saying that in the past, engineers would take a lower salary and work longer hours due to the prestige of working in the industry, or on a specific game. If they made those sacrifices and the game never even shipped, it would be disheartening. Though to a contractor, all billable hours are created equal.
Tesla presented the best in class Powerwall for an unbelievable cheap price. Everybody said at that time: impossible. Elon said: "We have this number of orders." Actually, you never heard of any significant deliveries. Instead: "We have this new Powerwall 2". Already, the first version of Powerwall 2 is already dropped before deliveries happened. There is only marketing of single prototype large scale installations.

The same with the solar shingle. Everybody tells: too expansive because of the expansive installation requirements because of the connectors. A (few) single panels are easier to install. But still Elon claimed the solar shingle will be cheaper than regular before energy payback.
