A COP of 5 is quite optimistic for a domestic scale heat pump, at least in the climate where I work (UK). Sensible values here would be more like 2 - 3.5 depending on the temperature gradient required.

This is a function of how big the radiators are and how cold the heat reservoir is, so if you plug an air->water device into some normal radiators its performance won't be good on a really cold day, whereas if you plug a ground->water or water->water device into underfloor heating it'll probably be pretty good.

The big question (in the UK) for per-dwelling heat pumps is whether the distribution network has enough capacity to meet the winter peak load - if everyone gets a heat pump the cost might have to include replacing a lot of substations and distribution wires.

I am interested in the question of whether you could have PV cells on your roof with a coolant loop that goes into a heat pump, and a thermal store in the house for buffering. Then when it's sunny you can dump some electrical heat into your thermal store whilst also use your heat pump to chill the PV cells, keeping them at high efficiency. When it's not sunny you can draw off your thermal store giving a high efficiency for the pump.

If the numbers came out right you might be able to be self-sufficient for heat using something like this, just by making good use of the radiation already falling on the house.
I'm using it at work to develop an API and I'd say that it's been a great experience. I find that it fits well with our use case.

I find it works well for when we need to collect information from several places at once which in our older API required several requests to REST endpoints. Now we have a single request and a much faster response time.

I don't follow this statement at all.
There's not a limit[0] on the amount of energy that can be supplied from renewable sources.

Preferentially purchasing green or greener energy sends a signal to the market to develop more green energy generation capabilities to meet those demands.

[0] within reason. Obviously there's limits to the amount of energy we can harness from renewable sources, but those limits are far higher than our total energy needs.

Anyone can control a (root) certificate - the problem is getting others to trust it. Legitimate use cases might be: You want to intercept (and decrypt) traffic going from your local computer to SSL/TLS endpoints (affects only you) for example. Less clear cut / nice example: Company wants to read your traffic and therefor deploys a cert like this on your computer, now can snoop on anything you do, https or not.
Containers or environment management solve this problem quite easily. All of my major projects have a conda environment alongside them, and I expect I'll be shifting things over to Docker containers as my org starts shifting things to the cloud.

Yes there are jobs. I have clients in small towns all over the midwest and there are plenty of jobs in all those towns. It is so very hard to find employees willing to work! I think my point though is that given the nature of this HN space, most of the "readers" have the skills to work remotely from anywhere. Make yourself a valuable and treasured resource and employers will want you to work, even if it is over a connection. I think the key metric is not whether jobs are available in a small town, but rather the nature of available Internet access - thanks to the decades old USDA Broadband initiative, many small towns across America have better Internet than larger cities, especially cities monopolized by multiple-system operators (MSO's). Many small towns do not. That is where one needs to be selective.
I have a (few) simple and possibly relevant question(s).
Why?
What is the motive?
I’m not sure I understand the intent of the words and dump. If someone wanted to help discord users from being harmed from an unsafe service they wouldn’t hate on the people they were trying to help and call them stupid nor would they paste password data and hijack accounts.

That being said it feels more like someone with enough power, drive and motivation to “terrorize” (since you’re throwing around terms like fearmongering) a mass of people.
Was this for credibility?
If there was a point besides pointing out security flaws what was it?
Finally what is in it for you?
Someone is likely to gain after all.
I would like some understanding, and reasonable answers, though I would also understand if you didn’t respond or feign interest.

The default red/green background colors should be lightened dramatically, eg ffcfcf and cfcfff.
The colored arrows should just be black imo.

People will fuss over red green color blindness as well. May want to add a small visual indicator that can be seen in a grayscale version, like a plus or minus above each box, or the words pro and con.

This is a starting point, an experienced designer should be able to find settings for a much better looking and functional default look.

This has been happening lately in my area of Orange County, CA. There is an investor here who has been buying up single family residences with large backyards and then the investor puts these "granny flats" in the backyard to rent them out. The average buyer will simply see the property as a 3bed/2bath with a large backyard for 500k while an investor will see it as 3bed/2bath with a large backyard with opportunity for expansion....well worth more than 500k listed market value.

> by offering them a fat deduction

A deduction from a number that they "invented". If appraisers (and basically the market) say the value is 0 but the IRS says it's $65 million who is right?

What if you have a regular piece of art that's appraised at say $1 million but the IRS says it's $1 billion? It appears the IRS's evaluation always stands. If so it's a perfect method to strong-arm at will.

> Last fall, the agency sent the family an unsigned draft report that it was valuing “Canyon” at $15 million. After Mr. Lerner replied that the children were refusing to pay, the I.R.S. then sent a formal Notice of Deficiency in October saying it had increased the valuation to $65 million.

And the strong-arming.

The key word there is currently, and it depends entirely on your local area what your mix of energy production is and how clean that is.

There's no net-zero carbon options on the market for natural gas. So installing gas-fired options for heating/cooling means that you don't have the option of choosing from a green energy source.

Installing electrical heating means that you do have that option - you can reduce the amount of energy you need through local energy production (solar PV, solar hot water), you can store energy locally reducing the need for off-site generation, and you can choose to purchase power from off-site generators that are cleaner.
Perhaps the electrical standards in Europe allow for it, but in the US, a normal plug outlet is not designed to safely transfer the kind of power needed to heat a home for long periods of time. I’ve also never dealt with a situation where a place needed to be retrofitted with a heating solution, in which case running electrical wires might be just as much work as gas lines, but way more expensive in the long run in the US as gas prices are super cheap.
I've found it quite easy to freelance on the countryside. There are businesses out here, and since most IT people live in cities there's a lack of them out here. Easy jobs, that pay less than a top job somewhere else, but living is so much cheaper that it doesn't matter.

Scientific cameras with 16 bit ADCs will usually, in my limited experience, have active cooling, eg a peltier element and some fans. Otherwise, 12 bit is probably enough.
Can someone clarify something?

A person owns things. When they die, the legal person ceases to exist. The things they owned are now owned by a new legal entity called "the estate." Inheriting something is the formal act of transferring ownership from the estate to the people who end up inheriting things.

If something is in the ownership of the estate and it gets destroyed, stolen, or lost, how will it be treated for tax purposes at the time of settling of the estate?

Exactly. The biggest mistake people can make is to assume that just because you would do it a different way....that automatically means everyone else would do the same. Not the case.

Obvious example is pretty much everything on amazon is marked up 25% compared to the next biggest competitor (gotta love the "free" prime shipping, right?) but people pay up because amazon will get you your stuff in 1-2 days while Ebay will take 5 days or longer. People will pay for convenience and they will pay a lot for it as well.
I wonder if there is an opportunity for derivative financial instruments based on valuable things that can not be transferred.

Think company stock in a private company. It may not be possible to sell it due to bylaws or legal limitations, but it may be possible to borrow against it.

What if there was a market for loans based on valuable but non-transferable things?

It all hinges on the question of whether something will eventually be transferable. You can make an argument that the laws that limit the transfer of ownership could be changed in the future.

> What is interesting is that some local internet providers in Kazakhstan used to inject their own ads into http websites their users visit.

Several ISPs (including some big national players, not smaller local/struggling/other ISPs) trialled that sort of thing in the UK in the mid/late 00s but there was a big enough ruckus about it that they stopped.

The really egregious thing about what some of them were doing is that they replaced existing ads so were basically trying to take money of the sites (they were at the same time also trying to get sites to pay or be considered "low priority" traffic so were trying to tripple-dip: get paid by their primary consumer, get paid by the sites, and take the sites' ad money).

It doesn't surprise me that it is actively happening in places there is less choice (so "voting with your feet" is not an option for telling ISPs what you think) or public outcry is less effective (or drowned out by more pressing issues the area might have).
There is no way you could justify assigning value to something on the grounds that "if laws change then it has value."

> Do the lower costs of living outside big cities not offset the lower wages?

At least in Europe I have found that while salaries can be a bit higher in cities (maybe 10-20%) compared to rural areas, the housing cost can be massively higher (200-500% higher). The difference between regional and capital cities is smaller, but can still be important.

This doesn't take into account other costs such as food (supermarkets are cheaper) and entertainment (mostly because there's less of it and mountainbiking in the forest is largely free).

I'm always surprised so few people seem to realize and take advantage of this.
That seems to be a very common bureaucratic flaw - the absurd position is maintained out of interest because of their job.

This is well known but the real question is how to prevent that in a reliable way that doesn't open up more problems?

I had a LiveVideo account. I had made a (terrible) music video made from clips of my driving around and sped up. I put it on my YouTube, but they ended up over-compressing the video so it was all blurry. (Fast-moving clips don't compress very well.)

At the time, some fairly medium-to-high prominence YouTubers (back when Peter Oakley/Geriatric1927 was the most popular channel) had moved to LiveVideo so I tried uploading my video there. They didn't re-compress it all and it was still high quality.

Time passed, and YouTube changed their rules to not compress so much. I re-uploaded my video (having to make a small change to avoid the hash collision) and it stayed up.

For example, most web frameworks are not necessarily designed to share data sets and related analysis among many users. As data becomes more and more valuable you can expect Shiny to play an important role in such data sharing platforms.

"Dwarf tossing is an activity in which a large person throws a small person. The venue often is one in which alcohol is served. It is often a source of livelihood for the small person, with the large person paying for the privilege. While dwarf-tossing is legal in many places, it is sometimes banned by law."

SEO Part That Many Bloggers Miss Out
100% agree. I was looking at buying a new home out here in Southern California. The new trend is "solar" on the homes....but the problem is that you don't own the solar when you buy the home. Instead you sign a contract with the solar panel owner and either buy the electricity from them or buy the panels outright....for an additional lump sum of 20k+. When you go to sell the home....you have to get the solar company involved and a bunch of other hassles. It is a bad idea to set it up like this.

Anybody can make one.

You can make one on your own computer, give the result to your friends, tell them to connect through you as a proxy, and intercept everything. The tricky part is that browsers are hard coded with a list of a few trusted root certificates to trust. In order for the home baked certificate you just made to do any good, people have to explicitly install it and mark it as trusted. That means you have to distribute your newly minted root certificate and get every end point device to accept it manually.

That's what's so sinister about Kazakhstan's approach: by issuing a governmental mandate for citizens install the certificate they generated, and restricting their internet if they don't, they are effectively bypassing the Internet's current trust system entirely and granting themselves cart-blanche access to all their traffic.

Everything starts with one.

If it turns out that Berkeley doesn't spontaneously erupt into rioting and general disorder because gas is being phased out, well perhaps others that were considering it will see that it's not such a crazy idea.

Exactly. I also migrated companies off from MongoDB after a total data-loss that even the vendor could not recover or explain.

Postgres is surprisingly capable, rock solid service that is always my first choice. I also used Riak in production for several years and the biggest problem was with it that the operations team forgot the root password because they did not need to login for a long time. :) I have heard great things about Percona XtraDB but I never used it. RocksDB is also interesting but it is just a data store not a full fledged service, based on it there is one service called TiDB that I have heard is very reliable.
I disagree. Markets react to election results.

> Women entered the job market due to birth control and legal changes

>> women entered the job market because they wanted to realize their ambitions and support their families

From a historical perspective, women entered the job market because a world war (ww1) consumed the pool of available men through drafting them to die on the front line and having a war engine that increasingly needed more and more resources.

We are talking about a change from ~20% to almost 50% over the time span of 4 years. Neither birth control nor cultural ambitions has that fast effect on society. War does.

Similar thing happened with google maps while they were never a monopoly by your definition because other solutions exist.
"(Also, my gut feeling is that when you're talking about "arguments" instead of "facts", "evidence" and probabilities, you're in business of convincing, not truth seeking)."

That's funny since for me it's the other way around, in philosophy "facts" are taken with great suspicion but arguments are fine.
