> Mutability is an essential feature of the Universe we live in. Everything changes, internally and externally, all the time.

That's not obviously true, actually. From a certain standpoint, the Universe IS immutable.

E = mc^2 means that matter and energy are never created or destroyed, just changed from one thing to something else. So if we abstract away the nitty-gritty details of what state it's all in at any given time, the total energy content of the universe is immutable.

More than that, while the passage of time creates an -illusion- of things changing from one state to another, within each instant of Planck Time nothing changes at all. And there's no conclusive evidence that the apparent CORRELATION between each state of the universe at each successive instant and the one that came before it is NECESSARILY a direct CONSEQUENCE of the previous state.

More than that, consider that the past cannot be altered once it has happened. And there is no conclusive evidence that the future is fundamentally different. Furthermore, while we only have access via sense perception to the state of the universe that we call "the present", that's no guarantee that "the present" is the only state of the universe with some sort of existence to it. Maybe the past and the future exist contemporaneously with the present, forever existing as they are without alteration. In that case "Mutability" stops seeming so fundamental after all.

In short, if we conceive of the universe as a data structure with infinite capacity, running on hardware with infinite resources–that is, if God wrote the universe as a purely functional program free of side-effects—them there's no compelling reason at all why that data structure must be mutable.

That you assert mutability as "an essential feature of the Universe we live in" is an artifact of the style of thinking YOU are used to. It's not at all obviously fundamental. That's just the paradigm you're comfortable with.

Haskell is useful, if for no other reason, as a forcing function to make you realize a totally different way of conceptually framing problems, solutions, and the universe that both exist in. In my opinion, it's worth the exercise to grow as a thinker.
Ok, but at least it would run.
> or do these KF people do doxing on sorts on other sites and use KF as a central place to coordinate attacks?

Yep. KF is their harassment HQ where they share information about individuals they don't approve of. It's creepy.
You must have a well insulated house.. as soon as I turn off my AC or heater my house very quickly becomes the same temperature as outside..
TC have a wonderful presentation, but like all YouTube channels, should be taken with a grain of salt. TC made a fair share of errorenous claims, some of which they addressed in follow up videos (definitely not all). One example they never addressed was in their dishwasher video where they explained how a dishwasher worked (which was good) and then pushed to stop using capsules in favor of soap powder. Using powder requires more maintenance because you'll have to buy special salt and run your dishwasher with it but this was never mentioned in the video. The capsules have this so you don't have to add anything else. If you followed their advice blindly, you could damage your dishwasher. Ask technicians what to use and they'll all say the capsules are better for your appliance. Always trust professionals over YouTube videos.
Cloudflare is not a monopoly provider at all.

You work PR for Cloudflare, right?
Heat pumps are air conditioning systems. They work on the refrigeration cycle.

Rural homes in the US tend not to have connections to natural gas utilities. If winter isn’t severe enough to justify a storage tank, the home typically has an HVAC heat pump/AC unit, and really high electric bills for a month or two.

Heat pumps have gotten better, but they’re never a first choice for heating for good reasons.
Like most “emissions saving” initiatives the crux of it is where the electricity comes from.

Burning something for heat is always more effective, cheaper, and produces fewer emissions compared to an electric heater. Heat pumps need to power a compressor, while there’s some phase change and pressure hacks to move the heat around, systematically it’s trading electricity for heat.

If you’re getting electric heat from coal fired steam that’s always worse than burning the coal locally to heat something, and this is true for all emission-producing power sources.
Does Haskell treat mutability as an afterthought? I thought constructs like IORef were for cases in which mutability is needed.
Oh yes they are, what you’re arguing is that they aren’t secret.
Employer compensation has almost tracked productivity..

Like I explained, the slight gap is due to a slight increase in capital's share of national income, and that is solely due to housing.
>Not working with fascists (yes, really) makes me much happier about cloudflare.

This is beyond comical.
The way I use these words goes like this.

Agile is what managers who have no clue about the agile manifesto do after they attended a mandatory, 6 hours long SAFe training. "Doing Agile helps the coding monkeys output three times as much as before? Gotcha!" When you prescribe the same sprint start day across the entire organization, that is Agile. If you have 6 weeks sprint commitment, that's Agile. When all teams need to estimate stories using Fibonacci, that's Agile. When the dev team needs to commit how much time they need for a feature that is planned for next year Q4, that's Agile. When the company needs an certified coach, that is Agile. When I need to create a Jira ticket and got it approved by three people to change the name of a small class, that's Agile.

I use "agile", when a company or product team understands that when writing software, you need to adapt to the things you find out. You don't know what you will do in 27 weeks and there is no point in story point estimating that stuff a half a year in advance. The company is agile when one team can use Scrum, another team can do Kanban, yet another can do whatever they come up with that works for them.
I didn't say it's wrong.

You may as well use {white, blue, black, red, green} to represent congruences mod 5, mathematically speaking it's not wrong, as long as they respect the axioms of a field.

What's "wat" (in the same sense as the js "wat" talk) is that the answer changes if the argument becomes negative. By all reasonable definitions of modular arithmetic, -8 and 7 are in the same class mod 5. Why is then:

> (-8 % 5) == (7 % 5)
false

in C-like languages? I'm pretty sure it's perfectly consistent with all the relevant language standards, but it's a "wat" nonetheless.
they should. in general, the main time they drop significantly below theoretical efficiency is when the cold end gets iced up which wouldn't be a problem here.
I'm sure the answer is going to be along the lines of "because PCC did that and they standardized it" :-/

Here's a fun standardization problem I came across recently (nothing to do with C): http://mywiki.wooledge.org/BashFAQ/105
Copy on write on a VMM is solid for a naive impl. but you need heavier stuff for prod I fear.
I use a personal NAS which solves that problem nicely. The other option that’s much closer to sneaker net would be use of a direct file transfer protocol like Airdrop. There’s also stuff like file.pizza, but that’s not always reliable IME.
High speed dubbing for the win
That's neither true not would it have been helped by making the original code require input during generation.

They put a simple check in, that tries to avoid returning nsfw images so that you don't get that back despite a more 'innocent' prompt. It's trivial to remove and is only part of the demonstration scripts, it is not part of the model or anything fundamental to it's workings.
40 to 55C is good for underfloor heating. Which in most cases unfortunately is way too costly to install, in an existing structure as you'd need to rip out all your floors and the ground beneath it, to allow for 8 cm of tubing in a cement structure.
What are they equipped with? True preppers are people investing in their skills among other things, getting ready for a time where supplies will not be delivered by Amazon. These people have money, and thus power now, but if society collapses money becomes worthless and they will have no power. They will have their bunkers, but somebody needs to keep the lights on there and supply them with food. Nobody will do that, they will just take it for themselves.
We could have an interesting discussion about the challenges of literal rocket science.

Or we can turn this into yet another bitchfest about government inefficiency.
A consequence of most, if not all, CPUs today using two's complement integers.

I think one's complement is more sensible since it doesn't have this problem, but it loses out because it requires a more complex ISA and implementation.
That's still a bad question: the behavior is implementation-defined according to the standard, so having "implementation-defined" as a wrong option is ambiguous and confusing.

The question would be fine (given that note) if "impementation-defined" was not an option, like for example the question about "SCHAR_MAX == CHAR_MAX".
There are units which exchange heat with water, but typically they won't reach more than 40-45 C°, maybe 50, I doubt 55, so radiators heating won't work, you need fan-coils or - better - under floor heating.

Additionally (it depends) usually pipes used in traditional radiator heating system are smaller in section (when compared to those used in fan-coil heating/refreshing) so your existing pipes may be too small to allow the system to work efficiently.

Personally I am not impressed by them, if not in direct small (split) systems, the exchange to water seems like losing a lot of energy.

But the good thing is that they allow, in reverse, to cool the house in the warm months (though not comparable to a traditional A/C system).

The 10 years duration sounds like what you can expect (to be compared to a traditional burner that would cost less than half a heat pump and is more in the 20+ years duration).

There is also the issue that (at least in my experience) they are "slow" when compared to a gas/kerosene/oil burner, so you need to keep the house somewhat heated at all times as it takes more time to raise temperature[1].

[1] there is a lot of debate around whether it is more efficient (with traditional fuel burners) to switch heating off when you are not in the house (potentially letting the temperature go down to - say - 8-10 C°) and boost to the wanted temperature when you are in or keep at all times the house warm (at - say - 13-15 C°) and only increase the temperature to 18-20 C° when you are in
It doesn't sound to me like the people in this group necessarily have much influence on environmental practices and the industries involved or on geopolitics. And one can't assume other people of similar levels of wealth think similarly. Or even what the men involved in this meeting actually think.

The entire article is assumptions built upon assumptions, with specious accusations and labeling throughout. It is sad to see much of the same in the comments.
Hydrogen is stuff from hell when it comes to engineering challenges. Not as bad as some of the "Things I Won't Work With" chemicals [0], but still. I am almost convinced that whatever direction the future carbonless energy production takes, hydrogen won't be a significant part of it.

Regarding Trump and his immunocapitalist behavior: I understand the position of the "Great Barrington Declaration" would be to make a majority of the population "acclimated" as soon as possible. Only lock down the vulnerable population. This could be effective because covid is not as deadly as yellow fever and not dangerous to a significant portion of the population. Setting aside all the Fauci political piss matching, I do wonder what might have happened with that approach.
Are you on Linux?
It’s called an economizer and is controlled by enthalpy sensors. Look into honeywell jade system, if you are handy then you can DIY it. Controllers are super cheap on ebay. Just be mindful of air balance.
That's really not an indicator of quality. They lack competition. There is some correlation there but that's a different story.
Page 79 has a bit of info on COP (efficiency) vs LLT (leaving liquid temp).

With intelligent management of LLT, your install will spend a lot of the year at 120°F or lower, where the efficiency is fairly high. If you end up with 2-3 days of COP under 2.0, that’s not catastrophic if you spend 40-50x as much of the season at COP of 3.5+.

You can probably find the outdoor temperature histogram for your area and figure out what your overall heating profile looks like.

But, if you need 150°F water a lot, AWHPs are probably not a good fit.

I hear people say this a lot these days, usually someone pushing some fringe cause from the left side of the divide. How has the center and right moved further to the right? I mean what issues have they moved on?
The correct answer for many of these is "don't do that". :-)
The French Revolution Created the Modern State
It's true that the existence of DDoS-Guard, VanwaTech, and a few others technically makes it an oligopoly, but you're still at the mercy of large corporations.

Nothing pays close to SWE without going into significant debt and losing years in training. Any rational economic actor will do nothing but software in current economy.
The main 'premium' feature I remember from that app, being the ability to play the audio/video while running another app, and not having restrictions about WHAT you could do that with.

Honestly that's a bullshit feature to lock behind premium, given a PC can do it without.

But then Google more or less gave them the 'fuck you' and made the app unusable. Which I still feel has some antitrust connotations, as they waited until the platform became competent to do so.
They are categorically the same when it comes to the moral question, because they're both spoken words that cause someone's wrongful death.

They are categorically different when it comes to the practical question of law regarding how we can come up with a system that doesn't pose undue unintended risks to free expression.

In arguing the latter, free speech purists are often incapable of communicating an understanding of the former.
I can think of a few:

* not ready
* in technical review
* in legal review (can all code be published under an OS license?)
* in security review
* missing documentation

I’m sure there’s plenty of other possible reasons. They seem to have a roadmap that they want to follow, so that implies they have thought about what they need in place to open source the components.
The Distinctiveness of Human Aggression
They're not above criticism, but what they've done is a very small layer that's easily removed. You can do it, and release a version without it, in minutes. You can do it in less time than it takes to write a long comment decrying it.

It's not fundamental to SD in any way, and their suggestion wouldn't have worked.
Believe it or not, this makes the behavior more like what you'd expect in many cases. For example:

uint8_t x = 4;
extern volatile uint64_t *reg;
*reg &= ~x;

In the last statement x is promoted to an int, and then when the logical NOT occurs every bit is set to 1, including the high bit. When it's converted to a uint64_t for the AND, the high bits are also set to 1. So the result is that the final statement clears only bit 2 in *reg.

If it promoted to unsigned int, then it would also clear bits 32-63.
Was your history book written by Ayn Rand?

Sure competition and allowing things to fail can, under the right circumstances, generate great advancements. But given the context of human history, it seems that decentralized feudal societies caused about as many technological revolutions as communist societies...
So I came to Haskell from Scheme background, so the tail recursion was actually natural to me. In fact, about a month ago I did 2016 Advent of Code in Haskell, and toward the end, I felt like I was abusing tail recursion [1] to write iterative algorithms like breadth-first-search by essentially "repeatedly consing on to the params of tails calls", as Lispers would probably call it.

The whole time I'm wondering if I'm just writing Haskell "with a heavy Scheme accent", since I see others' Haskell code make extensive use of state monads (which I still haven't attempted to understand), and I also found others' using way more of the monadic / applicative operators like "bind", etc than I have.

I found the hard part of Haskell not the iteration, which from tail recursion was completely natural and straightforward, but rather worrying about the efficiency of the "repeatedly consing" part. For things like stacks, the cost is O(1), but for things like Data.Array, I wasn't sure how much shared structure there was; I mean it could totally be copying the entire array every time I "mutate" an element (not really, since it was still sort of "consing" onto the old array and not actually mutating it).

Am I the only one who thinks this author is absolutely full of it?

Sorry, but he writes like an 8th grader. 99% of the sentences in this article could be popped into /r/iamverysmart.

Why would a group of 5 random billionaire preppers "trick" him into coming to talk about their elaborate doomsday compounds. They gain absolutely nothing by talking to this guy.

And why are they asking this random author "Should my compound have its own air supply?"

Sorry but I genuinely think this author just made this whole thing up, or is severely exaggerating what actually happened.

Do billionaires have preparation for global economic collapse or planetwide warfare, up to and including a security compound for them to flee to? Definitely.

Would they talk about it with this pseudointellectual, for absolutely no reason at all.. to ask him questions about their builds, or whether or not they should have their security guards wear collars? Absolutely not.
>There's no evidence that Apple is refunding banned developer accounts, either for the yearly developer fee or for unpaid App Store sales.

I'm not really sure how that's relevant here, we're discussing hypothetical regulation that scarface74 is proposing.

>In fact, a few of my indie developer friends have gotten their monthly App Store payments held up by Apple while Apple investigates so-called "unusual activity" (which turned out to be nothing).

This is likely unavoidable as Apple is subject to a number of AML regulations.
That’s called an air side economizer, they’re very common in commercial buildings but residential units are also available.
Obviously we're not. Icons and emoji aren't characters -- you don't need them to write words and their meanings are relatively self-evident as opposed to letters where you have to learn how to pronounce an otherwise mostly arbitrary squiggle.

And aside from emoji (which is demand-driven), Unicode isn't inventing anything, it's codifying things that already exist.
What you described here is perfectly consistent with scrum, which Holub and Farley ridicule.

> feed the results into next cycle

Right, so you have a concept of cycles; in scrum these would be thought of as sprints (larger cycles) or single days of work (smaller cycles)

> transparency -- you can't fix what you can't see

Yep. In scrum, this would would be addressed by daily scrums (transparency and coordination on a daily basis), sprint reviews (transparency about the finished cycle), sprint planning (transparency about the next cycle), and sprint retrospectives (transparency about the way the team works)

> improvement loop

In scrum, that would be sprint retrospectives with a commitment to attempt to address at least some issues raised during a retrospective in the following cycle.

> once you learned you need mechanisms to preserve the results

In scrum, those would be backlogs (for the product and for the sprint). The practices specific to software engineering, such as automation, infrastructure as code, etc., fall out of the purview of scrum and will be picked up by other engineering practices (CI/CD, version control, etc.)
What a glib article!
It was about as horrifying as reading about a hypothetical article on Industrial Engineering takeaways from the Third Reich.

The East India Company was an exploitative, ruthless and dishonorable organization that put millions of people in the Indian subcontinent to untold suffering.

Perhaps, the takeaway is to learn NOT to do that?!
What? No, this is incredibly short-sighted. It overlooks the fact that much grid energy is renewable already and will become more so in the future. Go with electric sources for cooking and heating (home and water), then let the grid handle being renewable.

Heat pumps are amazing technology and moving heat, vs generating it, is incredibly efficient and clean.

Do not burn fissile fuels in your home.
You seem to have only half understood?

The heat pump is only moving the heat. Burning coal doesn't move heat, it makes heat by destroying coal. Because the heat pump isn't making the heat it is able to move the same amount of heat from somewhere else (say, the outside air) into your home, using less energy than you'd need to make that heat inside your home.

Because you can't destroy heat (thermodynamics) for refrigerators we have no choice, we must use heat pumps. But once you get good at this technology, it's just better regardless of whether you want to move the heat away (Air conditioning, refrigerator) or towards you (heating a home).

This is how heat pumps claim seriously > 100% efficiency in many cases, they're comparing the efficiency of moving heat against making it.
Famines were common and cyclical in India prior to British colonization as well. There are certain ones you can pin on the British, like in 1943, but it would be a feat to get close to the deaths from communism.

And even then you’re comparing an empire that was quite openly exploiting who they viewed as lesser people, versus governments who devastated their own populations through good intentions.

(I also find it funny to see the top response criticizing the obviously Indian author for failing to talk about something other than war and famine. Folks love their poverty porn, huh?)
DS_Store just includes basic window configuration information for Macs. Stuff like list vs icons, size of the columns, etc, so you have a consistent UI look when you're accessing your remote drives.

It can be toggled to avoid it on removable devices when they're connected to Macs. It's benign, though I guess annoying to some non-Mac users.
Absolutely. The limit isn't in what you ask for, it's in what's returned. The whole point is to try and stop the user being shown nsfw images despite sfw prompts, and since you can generate multiple results per prompt adding an interactive check on each one doesn't make sense.
>A refund does not make you a non paying customer. In the same way getting injured by a faulty product can't be resolved with "fully refunded, they're not our customer anymore".

A faulty product that simply doesn't work can totally be resolved with "fully refunded, they're not our customer anymore".
The population in most western countries are rising because of births + immigration. If just looking at births alone, then most of these countries would see declining populations.
It looks more similar to Locomotion.
