Actually, it turns out modern inverter-driven air-source heat pumps (either mini-splits or the highest-end ducted systems) are almost as efficient as ground-source heat pumps, at a much lower installed cost. Basically, GSHPs are now sort of a boondoggle, except in the coldest climates that don't have access to natural gas. Yet the government of the U.S. still incentivizes installing them with a huge 30% tax credit, with nothing for high-quality ASHPs.

So its actually a good thing that most people don't consider GSHPs, they should instead be considering 20+ SEER ASHPs.

> You had all this before social media. In school I have been made fun of, I have been beaten, people have stolen from me and destroyed my properties. They made pranks, used peer pressure and had huge vanity and popularity contests, while all playing the conformity game..

I think the difference is that social media gives a number by which that your success can be measured.

> social medias just magnify the characteristics of the existing society.

But the problem is that it does in an unnatural way that is prone to various kinds of manipulations. In other words it awards dishonesty. Some examples are posting an heavily edited photo, or not posting something that you want for fear of negative karma etc..

One mistake I see a lot is leaving debug that causes sleeps to occur during thread execution. So while it may still be faster than a single thread, the sleeps slow things down more than it could be.

I see this debug pattern in a lot of tutorials, but no explanation why they show it, and no guidance when to turn it off.

I have also seen bugs that rely on the sleep for functionality to work correctly and have had to fix logic to turn off the sleep. So it is good practice to test production release mode after initial development in dev release mode.
When those niceties are not a free choice, but "strongly encouraged" by management, they quickly stop being nice.

For a person who spent a lifetime at the firm (which used to be pretty common in Japan) and is retiring from work altogether, they may be a warm touch. For someone who hates the job and wants to leave, maybe not so much. Not burning bridges is always a good idea, but I can understand avoiding long, scripted performances in this case.

I vaguely remember that Soviet Union had a tendency of sending some political opponents in psychiatric wards to be treated as mentally ill.

Does anyone know if there have been studies or reports that indicate whether this sort of technique works in the long run? In addition to it being inhumane, I can see it going two completely different ways: either getting rid of political opponents/Muslims/... or fostering revolution/martyrdom.

"If you tried to claim that a person's physical strength could be measured with a single number"

Its consistently measured as a single number by the US military - it's just a combination of your performance on several exercises - traditionally pull ups, distance run times, swim times, number of crunches, etc.

So, again, fitness is consistently measured as a single number by one of the world's largest organizations. Don't postulate it's absurd. The same aggregation can be done for intelligence.

Other than that I am pretty sure we can find many more examples.

This statement could be made much more interesting and convincing if you provided some actual examples.
It's typically referred to as "general intelligence," or "g," and the reason this single value is significant is because of the strong correlations it has with other life outcomes. I don't think anyone claims it represents all intelligence, and presumably we could come up for numbers regarding other aspects of intelligence. It's just the best number we've got so far for what people are trying to measure.
Couldn't you also argue that (and I appreciate there are exceptions to every rule) more gets done, with more efficiency, when everyone is together in one place? Certainly when reading body language, micro actions and the "feeling in the room" is important and video calling doesn't cut it. So they end up in one place. You could move that place to somewhere with great air, but because it's a centre of importance and a community of people is needed to support it, within X number of years enough of a city will have built up causing the same kinds of pollution and you're back in square 1?

The same applies to heating. Even when it is below-freezing people heat buildings to the point that you can wear a t-shirt indoors. Instead of wearing more clothing, or enduring slight discomfort, people waste energy.

One particularly annoying example is the train. The trains always have the heat blasting. I, like most people, have to walk to the train, and stand on the (often outdoor) platform, so I wear clothing that will keep me comfortable while walking, and while waiting on the platform. As soon as I'm on the oven-like train, I have to strip off all layers to avoid sweating. I assume this is for the benefit of people who do not dress appropriately for the cold. I would prefer that they optimised for the opposite.
Really? I live where it gets below freezing for months. At these times the ground continues to be what, 55 degrees F. How can an air-source pump be anywhere in the ballpark of efficiency?
Retardation, by definition, is something backward, and RISC-V instruction set is backward, since it is empathically not an improvement over what we already have in OpenSPARC or MC68000 in terms of clean design or intuitiveness.

Based on the amount of carbon monoxide and other pollutants that enter a car's cabin at highway speeds, this is likely a huge cause of road rage, speeding, and other reckless driving behaviors.

Company HR will ask you to sign a bond once you get selected in the visa lottery. We have to sign this bond if we want them to go ahead with our H1B process. This is different from the bond they have for freshers (which usually lasts for 2 years at the start of your career).

Once we sign this bond, we have to accept whatever salary they offer for our onsite assignment (deputation to US). People won't even know their US salary until 1 or 2 days before travel. Then come to US and work for them for the bond period doing whatever they tell us to do. If we were to quit during this time for another job in US, HR can treat us as "absconding" and refuse to give the service letter unless we either pay the bond amount or come back to India and serve whatever notice period is on the bond.

As an Indian living in India, this saddens me a lot. India has perhaps the world's biggest share of most polluted cities [1], and there are next to none measures taken. PM 2.5 in Delhi regularly shoots beyond 200 (while general guidelines for good quality air is <50).

The sad part really is that the pollution is more of a political and enforcement problem than a technological one. And none of the wonders of our technology will help us solve the "messy" problems that occur in a democracy of heterogeneous people (of India).
I think in general it's a mix between parents choice and society.

I noticed you didn't want to use the word government there and instead used "society". More often than not it's unelected bureaucrats doing the regulating, so it's not "society".

Besides the places where that's not really an option, you're assuming that's even an idea than can actually pop in anyone's head.

Ask HN: Running your own Private E-Mail server
At the moment I am just using gmail, but I'm fed up with the amount of snooping google does, I want my email to be private again (if it ever was).

I have considered a privacy focused provider like Lavabit or Hushmail, but are they really private or just a marketing gimmick? If their efforts are legit, does this not just make them a target for NSA etc? For $50 a year, Im not convinced.

For that sort of money I would rather get my own vps and setup a truly private email server.

Has anyone tried this? I looked at qmailtoaster and some other off the shelf scripts but couldent get a decent setup. I have setup a postfix + clamav + spamassasin + dovecot and so on, but its a lot of work and not something I look forward to doing, is there a better alternative?
Yeah, I believe that the key point here is that regulations should prevent "harm" to others, not "self-harm". And as far as I know, that's how it goes most of the time.

DNS cache poisoning happens at a surprising rate. I had Verizon FIOS's DNS serve the wrong IP address for "www.google-analytics.com" before, for over 6 hours. The IP they returned for that hostname was located in Isreal, and was serving up malware in the analytics.js script on any page that included it.

Luckily www.google-analytics.com is HSTS preloaded, and the cert the attacker served wasn't signed, so the request was blocked.

But now imagine that instead of doing that to www.google-analytics.com, they did it to yoursite.com, but you don't have HTTPS enabled, so they are free to send whatever scrips they want to your users, return whatever data they want to their server (which the users's computer thinks is yoursite.com), and can even do a 301 redirect to their own domain after the initial attack to make sure they can keep unsuspecting victims under their control for long after their DNS cache poisoning gets fixed.
Only if you want "intelligence" to be a fixed characteristic of a person. Which would be a strange requirement, since other characteristics can and do change a lot, especially with a targeted effort to change them.

Participation sports can go a long way for some of this. Developing strength and fitness naturally builds self-confidence and a positive self-image. Self-confidence results in a willingness to defend oneself and helps deter bullying.

The avocado toast index: How many breakfasts to buy a house?
It's quite obvious that social media provides utility to their user's lives, but there is much more to consider. When sitting in a lecture hall a quick glace across the room reveals that nearly every student is scrolling through Facebook or Instagram. That's a real issue. They can't sit their phones down for one hour to pay attention to something that will benefit them in the long run. The main issue is that users aren't able to moderate their usage. It's the first thing they look at in the morning and the last thing they look at during the night. It may not be clear to them that there is much more for this life to offer.

Sure, but so does simply calling folks and/or having them check in in many cases. Some places do such things already.

The system is cheaper than keeping folks in jail as well. Some civil servant can call folks and leave reminders and such. No need to pay for food and housing. And a great bonus: The person's life isn't so negatively affected before they are even found guilt or for crimes that wouldn't usually have jail time.
Firefox used to have Tab Groups, it got removed but the webextension API got some new features specifically to support similar functionality in an extension.

i.e. https://addons.mozilla.org/en-US/firefox/addon/basic-panoram...

In reality I think it's just not a priority for browser devs because the overwhelming majority of users do not use huge numbers of tabs.

Hi, author here.

As a user of both travis and gitlab-ci I wanted a more unified and simple deployment experience across various providers, whether it be GitHub releases, Heroku, Firebase, AWS S3...

As said rocket is the D in CI/CD: It allows to easily deploy software across a large range of providers from any CI/CD pipeline.

It does not replace your build system but instead help you to easily push your code in your various environments (dev, staging, production...).

It should be as easy as possible to use, Any feedback welcome.
I was like that in my twenties in well, now it's no longer an issue. I dunno if it's because I got my life in order (much more excercise now) or if it has just changed with age.
How My Team Accidentally Moved to TypeScript and Loved It
I don't know about India, but in UK if you have a notice period on your contract and leave before it's served, then the company can totally sue you for the work you promised you would do and didn't. So yes, a company can totally say "you can leave right now without working your notice period, but you need to pay us the equivalent of your salary for that time". Or they can say you can't leave until you worked the last day of the notice period - it's their right and something you have agreed to in the contract.
The US must be way more polluted than China and India then.

A Link Tax Won't Bring Back Journalists; It Will Do Even More Harm to Them
Imposter syndrome is real. I’m educated, have worked professionally in my specific field for four years and I do side-work as an examiner at academy level (something I’m certified for). I’ll often feel like I’m not good enough when I join a new project. It’s stupid, but it’s also a real thing, and it’s not always easy to deal with.

Of course there is also being in over your head.

Try to figure out which category you’re in. Then ask yourself three questions.

What have you learned during your three weeks?

What do you still need to learn?

How can you achieve that?

Lastly I’d have an open talk with your manager. It’s his/her responsibility to get you onboard safely, and maybe it’s time to try another approach? It’ll help if you have answered the three questions, because they’re really the foundation for your way forward.

Disclaimer: I’m Danish, we may do management differently.

This appears to be a form of the "pipeline" argument, that the problem with low participation rates by some demographic groups is due to a lack of those people in the earlier stages of the career pipeline to the workplace.

The thing to understand about the pipeline problem is that it is the same thing as the hostile/discriminating workplace problem. The pipeline leaks at every stage, from kindergarten to the boardroom, because some demo groups are supported, assumed capable, etc, and others are not.

So the solutions are the same at every level: workplace and school policies that explicitly correct the inequitable treatment, both structural and individual.

We'll have to agree to disagree about Django. I think Django and Rails both offer good developer productivity/velocity, they just make different tradeoffs. Django tends to be more explicit, which might lead to a slightly higher learning curve, but after that I've found it's easier to trace through Django applications to understand what's happening.

I've seen my fair share of terrible Django and terrible Rails applications. Bad code can be written in any language and framework.

Don't get me wrong, Django definitely has its pain points, but I think it offers a very competitive alternative to Rails.

I definitely agree with you on Phoenix though! Elixir/Phoenix is my current stack of choice. I actually think they do a really great job of capturing the high points of both Rails and Django while also improving on the weak points of both as well. (For example, Phoenix offers a lot of the "magic" of Rails but it's all backed by explicit code that Phoenix generates while creating your project.)
I've left all social media platforms other than Snapchat, Reddit, and Hacker News. I only use Snapchat because my girlfriend likes to use it and she's literally the only person I use it with. Reddit and Hacker News are generally entertaining and can be a good tool if used correctly. The biggest hurdle is not using these sites for procrastination. Reddit actually maintains a higher average in regards to user interaction on each individual visit than Facebook, Instagram, etc.
