"Lisa, in this house we obey the laws of thermodynamics!"

It's physics and thermodynamics. It's basically the same as with any heat engine, internal combustion engines included.

There is a certain maximum theoretical efficiency that is not 100%. When we build real machines (not theoretical ones) there are real world losses like heat loss, fluid flow friction, moving part friction, electrical inefficiencies, etc. Those real world losses van be gradually worked on over time, improved incrementally to yield small gains in efficiency. But never large ones, and never more than the theoretical max efficiency, which is not 100%.

It's like hybrid cars (not plug in hybrids, but just gas powered hybrids), they've doubled or trippled the mileage compared to a comparable regular car, but they will always need gas, they will never be 100% efficient.

Same with this. There will always be some fundamental electrical losses in the copper in the motor, air gap losses in the motor, friction in the bearings and fluid, heat losses to the environment, etc. It's the cost of doing the work. There is no free lunch, so we can only incrementally improve the little losses over time.
An explanation I've heard is while people might support an issue, as shown in polling, they don't feel very strongly about it compared to other issues. In that sense, many (most?) opinion polls are not predictive of voting in any significant sense.
"Iceland's defence forces consist of the Icelandic Coast Guard, which patrols Icelandic waters and monitors its airspace, and other services such as the National Commissioner's National Security and Special Forces Units. Iceland maintains no standing army, the only NATO member for which this is the case.

The Coast Guard consists of three ships and four aircraft"

It can operate efficiently at lower temps. Current air source heat pumps see degraded performance and below freezing temps and will not be able to effectively heat a home at the lowest temps that can occur in the northern hemisphere.
>And here's the best part: They have the strongest magnetic fields ever observed, so strong they can melt you—literally dissociate you down to the atomic level—from a thousand kilometers away.

Why should they destroy a human or anything that does not have an magnetic field or it's made from iron?

Inflation is and always has been about changes in the price level. If velocity halves and money supply doubles, there is no additional price level change - so it is not a "fundamental cause."

When banks issue mortgages, they don't decrease a number in their own accounts to balance it. The act of creating the mortgage itself creates new money out of thin air, the act of repaying it destroys the money again. This is fractional reserve banking and is how most money is created. It's also why there's a relationship between interest rates and inflation: raise interest rates and borrowing becomes more expensive, so it happens less, so less money is created.
Do you apply these same arguments to other moral hazards like pollution?

Wanting to regulate social media (when there are no meaningful regulations) is hardly tyranny.

By old standards it's a huge server with a gigabyte of RAM memory and tens of GB of disk (maybe even SSD). Traditional text BBS's ran on 8 bit microcomputers with 64KB of memory and maybe some floppy disks, or perhaps a hard disk in the tens of megabytes, I thought.

I do like the idea of raw text. Leopold Kronecker famously said that God created ASCII, but Unicode is the work of man. Or something like that.
"Because copyright ownership still has to be enforced through the traditional IP and legal system."

Correct me if I'm wrong, but isn't it even worse. There is no transfer of any rights whatsoever on the common trading platforms so I assume copyright ownership is rare. Consequently in most cases there probably is nothing to be enforced. At least that is how I understand NFTs.

Pens in general are terrible for me as a left handed person. The only ones I like are the Frixion pens, as their ink seems to actually dry fast enough to not cover my hand in ink. Really writing as a left handed person feels like a fool’s errand. It just wasn’t made for me.
No it’s actually much easier to correct at the government level because it forces bad actors to rectify their behavior. Blaming the individual is such a weak argument, especially since the deck is stacked against you as an individual.
I don't see why this would cause people to vote differently from their beliefs on a referendum on the exact issue. This seems like a generic reason why people might vote for politicians who support things differently than how they are polled, but not responsive to what I am saying.

I really appreciate how Godot is the only one of the 3D engines that not only offers good 2D support as well (like say Unity) but really treats 2D as a first class citizen. I also REALLY appreciate how it's the only one that has decent built-in support for vector drawing.

That said, so does Canvas, and HTML & CSS are a tried and true portable powerhouse UI combo, and JS/TS are infinitely more relevant than GDScript, so I am camp Electron. Especially now that web 3D is also better than it's ever been. I would rather see more work to make Electron gamedev-friendly than work to make Godot appdev-friendly
A couple things off the top of my head:

* some folks had to deal with a LOT of submodules back in the day; for instance, it wasn't uncommon to have a dozen+ in your "vendor/plugins" directory in a Rails 1.x app. More submodules, more problems

* sometimes submodules get used to "decompose a monolith" into a confusing tangle of interdependent repos. Actually changing stuff winds up requiring coordination across multiple repos (and depending on the org, multiple teams) and velocity drops to zero. Eventually somebody declares "submodules SUCK!!!!!one!!!" and fixes things by re-monolithing...
Lab vs typical observed performance differs quite widely for many home heating systems.

Thats because typically each appliance is tested at optimal conditions (eg. water flow rates). Then, in a real deployment, every parameter differs a little from optimal (eg. the water may circulate slower than expected because you have longer pipes around your home than the lab ones, and your hot water tank is hotter than expected because you like it set hot, and your airflow is less than expected because the filter is a bit blocked, etc.). Each knocks a few percentage points off the efficiency, but the overall impact can be dramatic.

We really need 'smarter' heating systems which can detect and correct for such things. For example, water and air pumps which measure temperatures and flow rates of air/water, and adjust speeds up and down to maintain the optimal efficiency point.
It has algorithms and heuristics that dictate how it drives, so I think this is more the programmers haven’t gotten to it yet.

From the article:

>The problem is that atoms are made of positively charged protons and negatively charged electrons. In weak magnetic fields, this doesn't make a bit of difference. But in strong fields, the electrons and protons respond differently. Atoms lose their traditional shape, and the electron orbitals become elongated along the direction of the magnetic field lines.

... your individual atoms would only be 1 percent as wide as they are long. With atoms turning into needles, atomic physics as we know it breaks down. As does all the bonds that atoms use to glue themselves together into complex molecules.

>In other words, the static magnetic field of a magnetar is strong enough to simply... dissociate you. All the molecules that you're made of simply come apart into oddly shaped atoms.

I also don’t quite get it. Firing that designer would not increase my trust in the design leadership.

It would seem thin skinned, skittish, cruel, deeply immoral and evil, leading me to lose a lot of trust, feeling as though creating a culture of fear is the goal. That behavior seems completely incomprehensible to me, especially since you need to have an extremely tortured reading of that e-mail to read it as an attack on Apple. It’s simply so extremely weird and wrong to do that. It also seems completely ineffective. What’s the intended effect here?

I’m not sure what the general vibe here’s on that, but it seems abhorrent to treat people that way.

I don't know if most people consider skeuomorphic designs obsolete/outdated, but the costs would be far greater today compared to when iOS was only for a handful of different resolutions for the iPhone and iPad. Not only do you have to consider the physical screen size differences with possibly different PPI, but all of the sidebar/split-screen/multi-window modes would require additional work.

It's kind of like when most websites started to switch to responsive designs where image heavy layouts and other fun animations kinda dropped off. It was just too costly to make things work well.

I think whenever HN readers deride a product because it doesn't suit them, that's not an effective argument. Like do you have any idea how strong conversion rates are on email? Or even paper mail? Stuff we all hate can be very effective at growing an audience. I honestly don't use Patreon at all and we rejected it as a platform for content monetization at my company, but I can also tell you that our first-party approach wasn't exactly a slam dunk.
The logs are what you have. It's like the investigation after a plane crash, where you have some black boxes, some radar images, observed distribution of wreckage, whatever. You probably don't have all the data you would like to, but you use whatever you can get your hands on.

Better tools for analyzing logs are fine, but the idea of some ML tool that you throw random logs through and have it automatically identify significant events seems like a pipe dream.
Ask HN: How can I be sure my work MacBook isn’t spying on me after work?

Which is always the problem when you ignore the negative externalities. One would hope those externalities might start to be internalised to the cost of burning fossil fuels for heat, then heat pumps might become a better prospect.

(Tbh, I recently did a high level analysis of a heat pump in a temperate climate, and in light of climbing fuel bills and the potential for low price electricity from renewables at low demand plus batteries, heat pumps start to make a lot of sense. You need to think about using them differently to gas though)

I imagine that parent is referring to the ability to measure the total possible information capacity of a signal, or a signal carrier. If you compare the size of the 'message' being sent to the size of the 'envelope' it's (hypothetically) being transmitted through, parent is asserting that the message doesn't fit in the envelope.

That information analysis falls within the purview of Information Theory, and the physical complexity of the types of molecules which give shrooms their psychological effects is limited, and therefore the maximum message size they can carry is limited. That's the physical analysis.

But that's all just off the top of my head. Hope it helps.

There were moderate Republicans who would have crossed the aisle to cast their vote for Bernie (according to polling) thanks to a strong ground campaign and (while poo poo-ed) YouTube and Podcast support as well as a strong minority support from African Americans and Latinos due to not just "expecting their vote" like the Democrats did, but doing the work and actually campaigning to them and addressing their concerns. Bernie support was stronger than was given credit, rather Hillary liked it or not, and that disenfranchisement was a large part of her loss, and led a lot of people to just not vote, or in the case of Latinos, vote on the single issue of abortion.
They are the first human-made objects to do so, a distinction they will hold for at least another few decades.

> The fact that the recursive method for calculating factorials fails for quite small numbers is a good reason for teaching it.

It's not much different. The primary reason why cryptocurrency aims for a limited supply is to eventually remove the politics around who gets newly created money. Friedman couldn't have imagined cryptocurrency, so had to settle for the next best thing of market interventions that were at least mostly automated, most of the time. This isn't that great because of course someone still controls and programs the computer.

There's a couple of technical reasons Friedman thought the money supply had to keep increasing:

1. he was a subscriber to the deflationary spiral theory, which doesn't make much sense as a concept but has a lot of subscribers in economics

2. dollars and similar currencies have very limited resolution because most payment methods can't handle fractional cents, so if one cent becomes too valuable you start to destroy products and services for which the best price is less than that. Bitcoin doesn't have that problem to anywhere near the same extent because the resolution of the currency is much higher, and the software can all handle very small values.

A bit of an aside, I really like the Ethiopian Wikipedia page on Amharic[1], an Ethiopian language written in the Geʽez script. Traditionally ፡ is used as a word separator in the Geʽez script to write Amharic (and ። as a full stop, looks like : and :: in case your browser doesn't render the fonts).

But more recently the space has become popular, probably because it's easier on computers and due to English/Western influences.

The nice thing about that Wikipedia page is that the first three – and presumably the oldest – paragraphs use the classic ፡, after which it mostly switches to spaces in the newer texts. Traditionalists will think it's horrible and you should stick to the "old ways", but languages and scripts have been changing ever since they were invented, and you can see the evolution of a writing system right there on a single page, which I think is kinda neat.

(Note I do not speak Amharic, I "discovered" this while researching different writing systems for some code I was writing).

Yeah, gel pens are vastly superior to standard ball points.

However, the fundamental issue of not needing to write as much as we used to I believe is dominant. I have abandoned using cursive because it takes practice to keep it readable--and I simply don't write enough. I can type faster on a keyboard than I can write with a pen and what's in the computer is more useful--paper is only of value when you need to do something other than make letters. At this point most of my use of a pen is filling out forms.
Nah. It's an whatever the opposite of that is, directed at the people who do improv. Improv is just a series of associative, impulsive reactions to stimuli - exactly what these systems are doing, following a series of words with the first (most strongly connected) utterances that come to mind.

It could seem like anthropomorphism if you don't think about it, but it's not anthropomorphism to say robots walk just because humans also walk.
> Crypto is meant to be an alternative for the cases where the cost of existing processors make the transaction not viable.

You drill smallish holes in the drywall in each stud bay, blow the insulation in through the holes, and patch them. This is much less expensive and less messy than removing and replacing drywall. It can be done with cellulose insulation, with fiberglass (the loose fluffy kind, not batts), and possibly some other products.
