There are many companies that deliver air to water heat pumps, e.g. Daikin, Mitsubishi etc.

Most of these — these days – seem to be for both cooling and heating, but I know Mitsubishi Ecodan have models for just heating. If you live in a building with pipes installed, the pipes need to be specially insulated to carry cold water, if not the moisture in the air will seek the cold pipes and form condensation thus causing humidity problems.

If you are looking into installing an air to water heat pump for heating your home, you can either use it for floor heating and/or different types of radiators (many solutions also offer sanitary water heating as well, for showers etc.) Sometimes you can use the radiators that are already installed in your home and just install the water pump system, but that requires that the water warmed up by the heat pumps is sufficiently warm (and that depends on the company/model chosen). If the water is not sufficiently warm, you either need to install a bigger radiator or newer types of radiators that are called low temperature radiators. The latter radiators are "smarter" and gives more heat at a lower temperature, but typically are also more expensive.

Here are a couple of links for more info. The video is more for illustration purposes, as models changes all the time. It is also important to point out that – in general – there are lots of different solutions on how these machines are assembled. Sometimes the outdoor unit contains technology that in other models are stored in the indoor unit. Sometimes the water container is stored together with the indoor unit itself, sometimes these are separate. It all depends on available space, or if you like things compact or not.

I have nothing to do with Daikin or Mitsubishi, I have just been looking into installing this in our own home. I am looking into an air to water air pump, and only for heat as our pipes are not properly insulated.

Even if one has zero empathy for prisoners, I hope it's clear how treating people like this will not lead to rehabilitation or a stable society. The most stable societies in the world treat their prisoners humanely and leave sentencing and treatment up to experts, not the opinions of politicians.
I tend to be too terse.
All well and good. Here's something that sounds totally crazy: the future of infrastructure and of software development is in self-programming/self-modifying systems driven by AI to meet a set of requirements. Not buzzword pitchdeck bingo, but systems that can figure out how to optimize, fix and add features to themselves. It's asking a whole lot to get there, but it's inevitable because the cost savings potential is cavernous. There will only be three job left: govt bureaucrat, elder care, and a million applicants vying to be the last remaining engineer who can figure out the latest combinator-based programming language written in BF this machine decided to create on its own.

While the Internet provides a platform for Essays, as he says, I think maybe a bigger point is it allowing the rise of 'Video Essays'.

Where now content creators are turning out 30+ minute videos on a single subject. While in the past it used to be more 'dry' things like History and the like it seems more mainstream subjects are being covered. Movies, cars, current social issues, etc.

And just how much you actually get from them. They're often spoken from positions of authority on a subject. And slick editing and video may reinforce their credibility to the viewer. But often they just feel like empty stitched together wikipedia clippings with nice effects and humor sprinkled in to keep the viewer interested.

Compared to crafting words and language like this Author tried to convey, you just rely on balance between entertainment & information.
I wish I could argue against your reasoning, but sadly I think you are totally correct. Here's to hoping we are both proven wrong.

I made a chez scheme backend for Idris a couple of years ago: https://github.com/melted/idris-chez

About the only notable thing with it (apart from inspiring the target for Idris 2) is that it implements the C FFI, so it will handle Idris programs made to target C.

While the internet is full of garbage writing, I don't feel like telling people that they shouldn't say anything wrong or potentially unimportant is the right way to go. That's a perfectionist attitude that stifles people's ability to explore, experiment, be wrong, learn, improve, and act. Like learning a language, if you never speak it because you're afraid to say something wrong, you'll never learn.

And separately, being enlightened with novel pithy facts isn't the only reason people write things. There's a lot that can't be transmitted in that form, and while I appreciate that style of writing for startup advice or a how-to guide, it's definitely not universally applicable.

Yes REST has a lower bar to entry. However, if you need to you can provide REST end points from a gRPC definition.

eg https://levelup.gitconnected.com/grpc-basics-part-2-rest-and...

We had the pleasure of working with some legacy SOAP recently - the other end had changed the WSDL such that our client no longer compiled from the WSDL - they couldn't work out what was wrong and where fearful of changing it again so we had to had to hand roll the client. Fun times....

I hope neither get as complex as SOAP - one of potential pitfalls of tooling is it becomes 'free' to add complexity.
As a counterpoint, I'd argue that the "mathematical" approach to good writing is inherently flawed. That is, trying to arrive at the formula for the "best" essay via dialectic (argument) is to miss the forest for the trees. Writing is an art, not a science. Formal logic was developed to display arguments, so if you are trying to be as precise and mathematical as possible, use that instead.

Instead, I'd suggest reading the great writers of the past and present (but focus more on the past). Study what works, what speaks to you, what stylistic approach you favor, and so on. As a bonus, you'll learn more about what has been said by other intelligent people and subsequently avoid writing over-confident, ill-informed essays...

If you're looking for stellar examples of essay-writing, I personally recommend Jorge Luis Borges and David Foster Wallace. Both manage to write in a manner both erudite and coherent, without seeming too florid or too simplistic. Here are a few samples:

- A New Refutation of Time, Borges:

The result is super fast: if you use if after using Idris1 you'll be blown away by how much quicker it type-checks. I'd never have thought a Scheme could perform noticeably faster than Haskell, but maybe most of the improvements are just due to algorithmic improvements made during the rewrite.
Er, may I ask why you'd think that?

Other than the notion of "layers of neurons", there isn't much about NNs that I would consider graphical - and that term is merely a remnant of the original motivation for NNs back in the day. Today, this metaphor has mostly been abandoned, and we think more about NNs in what they really are: combinations of linear and non-linear functions.

You may be thinking of sequence processing where a basic network is repeated in various different ways. This is already today often displayed as a graph of sorts.

But I don't see how this would obsolete using a programming language. The strength of visually laying out a network architecture is in communicating it to other humans, not to implement it for a machine.

To 'raise awareness' of weather events, as if one might not notice them otherwise. To be less cynical, people might pay more attention to weather warnings if they are named storms? Not sure how long that effect will stick if we have a named storm twice a month! I think you might not be far wrong saying it's about grabbing headlines.
Actually most of the warming is due to milder winters and at more extreme latitudes. So even if variation increased, it could still result in fewer very cold days.
Racket (and PLT Scheme before it) has always been a bunch of languages, keeping a few different syntaxes and semantics around isn't anything new. I don't get why having another take on the surface syntax should cause all that much anxiety.

Yes but once the json has been validated once at runtime, you know it's safe for the rest of your program to use.

Whereas in a dynamic language (even an immutable one), your data could be mutated during program runtime and no longer conform to the type you expected. Yes you could re-validate it everywhere, but that requires you to exercise every code path when testing at runtime to find bugs.

I think the general argument that "You can't static type everything (like your API dependencies), so there's no point in doing it all" isn't a very solid one.
Neither is objective. There's no pretense of objectivity in the legal system. This is why you see people say things like "we'll find out if this was legal when they rule on the case".
You don't need these clients, though, they're just doing HTTP. Isn't this just a quick way of reducing boilerplate?
This is just effective communication though?

I don't understand why your post is phrased so negatively. Some buzzwords have a sort of standardised meaning across a company so everyone knows what you're talking about.

"We agreed that delighting clients is important and I argue that I can better optimize it by not attending"
There is nothing wrong with this?

Sure I'd agree customer satisfaction is a much better word for it.
Oh "values". This meaningless buzzword has creeped into every facet of modern life. From politicians and their "western values" to CEOs and their "values" to baseball teams and their "values", everyone uses "values" to justify their evil or to defend or excuse their evil. And of course there is the "alignment" of "values".

Oh, stealing signs doesn't align with your team's values. We benefited from it greatly for years, but it doesn't align with our values since we got caught.

It's like an amoral organization's PR version of "my mamma taught me better than that". Some juvenile delinquent gets caught stealing from the store and he says, "I don't know why I did that. That's not me, that's not who I am, I'm not a thief. My momma taught me better than that." If he incorporated himself, he could've said, his actions did not align with his values. Problem solved.
That effect is probably much more so about where the language is used (US vs elsewhere primarily) rather than how much people get paid for that language in a particular place.
It's interesting that you say that. I have war-stories that are so similar to this as to come close to giving me PTSD. If you've never been in a situation where you have the "one hero who's smarter than everyone else" then perhaps you can't empathise with this.

But I can.

I don't actually have a clue about this stuff but I think wind turbines actually won't produce any power when the wind is too strong because they might break or something.

This may not sound the way you intended.
I worked in a somewhat similar project in 2015, though not as complex as this, to build background videos for DotParty, using UE4 for panoramas and then stitching them. One of the hugest issues we found was that, because of this being a game engine, a lot of things are not deterministic, so if we used multiple cards or computers, particles and other environmental effects would not be in sync, and the stitches were glaring.
That's fascinating, thanks for sharing
We're seeing prices for electricity as low as 0€ or less because people aren't using it efficiently. Part of that is because there is insufficient storage capacity, preventing it from being used when there's more demand and less wind.

But another part of that is that retail prices don't correspond close enough to market prices, so people aren't incentivised to use the best source of energy available at a time. An electric heater isn't that expensive. An app that broadcasts the current energy price is probably a little more expensive, especially since the company that produces it will want to add as many expensive lock in features as they can.

The German marketplace is remarkably inefficient. It's extremely difficult to cancel contracts here for instance — you most commonly have to do it several months in advance, or else they will automatically extend themself without the actual, legitimate consent of the client.

There's many problems but most of them are caused by bugs in the German marketplace which could be fixed by regulation intended to improve efficiency. For some reason, all the regulation here is intended to reduce efficiency.

Ask HN: Are DevOps increasingly becoming managers to Software Eng. teams?
Hi,

I notice a recent trend where DevOps are managers to Software Engineer teams.
I am wondering if there is any industry trends influencing this change, or it is a subjective observation that I personally hold. So I would like to hear what you all think.

I believe this change is influenced by the trends in infrastructures we depend on, as programmers. As our code is becoming more pluggable; with approaches like serverless or microservices.

Control over modularity of our code, also means control over the people that produce it. Thus it definitely makes some sense.

But there are many aspects of production of software engineering, that needs special care and attention other than the aforementioned modular pieces it produces as services.

Do you agree?

Where does this take us as Software Engineers?

Do you face any challenges with your work in connection with this?

Do you feel less or more ownership as our produce becomes more pluggable/modular small pieces of the whole puzzle?

I am sure I will get some responses as "All programmers need to know DevOps!"
In Japan, the typhoons are just numbered. “Let’s not go out this weekend, Typhoon 12 is supposed to make landfall”
So it's a pointless and artificial comparison? Because as far as I know, heat pumps are paid by the end consumer and not by "market price participants". Who are they anyway?

If your bank is in EU, you can ask them to look into this EU regulation about strong authentication methods:

https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX%3A...

> Dynamic linking is possible through the generation of authentication codes which is subject to a set of strict security requirements. To remain technologically neutral a specific technology for the implementation of authentication codes should not be required. Therefore authentication codes should be based on solutions such as generating and validating one-time passwords, digital signatures or other cryptographically underpinned validity assertions using keys or cryptographic material stored in the authentication elements, as long as the security requirements are fulfilled.

My bank (Swedbank Latvia) used this regulation as a pretext for removing authentication via passwords + code cards. They didn't do too well on the "technologically neutral" part though – you now have to use proprietary software or hardware to authenticate :-/
"$0.02c" - does this notation mean 2 cents? Honest question, not American and never seen this format before. Is it considered more clear than just "$0.02"?

The other day I was helping friend with an essay and i realized how 12 years in software programming has changed my writing style. Now it seems very awkward to think and write in long paragraphs. It feels more natural to use bullet points for everything.

> The subsidies are (overly) high so that lots of renewable energy production/infrastructure is built

In the first half of last year a total of 35 new wind turbines were added across Germany[0], the lowest rate for 19 years.

If German government policies are supposed to encourage the creation of new renewable energy production then they don't appear to be working particularly well.

These differences exist because of the freedom given to everybody about their choice. So countries make their operating standard and citizens follow it.

It is simple to think that this format would work but the people who are not familiar with this format will be completely lost with it. People who are not educated but somehow learnt to follow one format; ask them to learn a new format; it will be so complicated.
Except when people use it as a verb as in "we need to root cause this".
Fair warning to anyone picking up Clojure / ClojureScript: it can make you less productive by making your old tools insufferable.

It's like taking an automatic 2.5L turbo Subaru w/aircon for a spin and then getting back into your 1.3L Toyota Tazz - daily driving won't be as fun again for a while.

Lisp "ruined me" for a few years because after trying it I couldn't stand using anything that dit not have macros and Paredit. It's like the saying, "Beware of tasting freedom; it can make you psychologically unemployable."

For example, dealing with the abomination that is JSX when I could just write a pure ClojureScript function that returned Hiccup data structures that gets rendered to HTML. And you get isomorphism for free (one codebase on client and server).

I initially switched to Clojure for Datomic (the killer app for Clojure, IMO), but now I mainly write ClojureScript and use DataScript (datalog on the client) in every project.
> What should an essay be? Many people would say persuasive. That's what a lot of us were taught essays should be.

Yeah, essays written for a class on persuasive writing should be persuasive. Because that's what the class is about -- students are supposed to be learning how to express their ideas about how things should be done to, e.g., their boss, coworkers, clients, potential investors, etc..

However, I hope no one's under the misimpression that all writing should be persuasive writing. Schools also teach classes on other types of writing, e.g. creative writing and technical writing.
Food stamps don't prevent children from suffering the consequences of their parents poor choices; people can and do trade those benefits for other things.

Children also get to suffer for policymakers poor choices of what the stamps should be spent on, and taxpayers get to suffer the cost of every benefit program duplicating income verification functions and other eligibility functions rather than having universal programs where the tax system takes care of the better off not getting unfair share of benefit.
