The newest phones actually even do dual-frequency GPS using a newer signal (L5). It's accurate enough to do lane-keeping.

Existing systems also supplement GPS network data with russia's GLONASS, as well as sometimes WAAS if the satellite gets picked up (WAAS is GEO system to provide for additional accuracy, since it's further and requires a path facing south, it's not often picked up on phones)
Having wealth does influence the ability to spend money and work on things like regulatory capture rather than productive investments.

If you just want decent video quality for a zoom meeting where everyone shows up in their pyjamas then I agree -- setting up lighting like I described is wasted effort.

But for example, if you are a teacher, or an instructor, or if you have a video meeting with important customers, you may want to put some more effort into presenting yourself. And the best bang for the buck is improving lighting.

Sitting in front of a window is a nice solution for an overcast day, but it doesn't work after sunset (currently around 4PM where I live) or on a sunny day with hard light. Unlike styrofoam boards, it's also hard to control the light because you can't move the window.

I'm not suggesting everyone should do what I said. I was just sharing a possible solution if you want to make good looking video.
There's way too much wealth worship in the US. Yeah most rich people are smart but not exponentially smarter than everyone else.

A lot of wealth is luck. But wealthy people (like HN audience) don't like to hear that. I can't find a link but there's controlled studies that show the richer someone precieves they are, the more they attribute it to skill. Even in studies where outcomes are completely randomized.

Usually it's something like this: grow up as a citizen of one of the richest countries in the world. Have fairly stable family situation where you did well in school. Family wealthy enough that you went to a good primary school too. Family wealthy enough to fix overbite, scoliosis, speech impediment, and most other things that would handicap you professionally. Money/connections/grades to get into a good college. Skin color, gender, and culture to not be dicriminated against. Enough intelligence to pick a well paying career (maybe top ~25%). "Gifts" from parents early in life where wealth has decades to accumulate. Things like gifted cars, college education, wedding costs, first house. Ability to take arbitrary career risks because you always have family and their gifts to fall back on.

That probably describes more than half of people in well paying professions. And it's all 100% luck. The path to millions when you've already got so much going for you isn't so hard. You've already passed the barriers that stop 99% of people.

Merit isn't wealth. Wealth is mostly luck and we shouldn't worship wealthy people like Gods, hanging on their every word.

There's logical ways to measure class mobility and the US does badly compared to practically every wealthy country besides the UK

Yeah, I'm personally skeptical that the recovery-mode SMB disk sharing is a practical replacement for target disk mode. The last time I had to use target disk mode was when the macOS Mojave installer corrupted my fusion drive, in such a way that the host would panic on boot. I was able to save it with target disk mode and a second mac. That machine was not able to enter its own recovery mode, so I don't see how it could have been repaired with this new SMB scheme.

This is pretty cool.

I've always hated how flashlights seem to fit everyone's use case, but never anyone specifically.

Yes, the lonely hiker might need the stobe mode, but most normal people do not. (let alone epileptics!)

The person using the flashlight to illuminate something they're working on probably does not need to illuminate nearby mountain tops (and will need 1/2 hour to recover their night vision after that)

and there are two bike light modes -- one to be seen, one to see.
I saw the comment as a tangential observation on play.

But there was a section in the article where it suggests that in nature, play is "expensive" - in that it costs precious energy (and some animals may actually put themselves in actual risk in the process).

So costing energy could be seen as what we view as labor. Working to be able to play, so to speak.

They picked frequencies that were unlicensed. And at time 2.4GHz was likely good balance between bandwidth(frequency) and available technology.

And the 2.4GHz was free because microwave-ovens used this frequency. As those licensing bands specially in 40s/50s would not have wanted to deal with potential issues. Thus it was designated for microwave-ovens. And later freed up for any use. Thus being available and free.

"Arte has ghettoized culture on a channel that nobody watches (...) it gives other state channels an excuse to avoid broadcasting these types of shows altogether" - Dominique Wolton, Research Director of France's National Center for Research (2010)

The statement equally holds true for German public broadcasting, which over the decades seems to have shifted focus on copying private broadcasters segments.

It looks as if some of the money goes toward Arte, as well.

Arte is payed for by France and Germany directly. No money of OP's fee goes to Arte

Yes, but one of those second order effects of inflation is the relentless drive for growth that's burning people out and contributing to climate change: inflation causes those with the most money to demand higher and higher rates of return on their investments (to keep up with inflation), which drives management (through pressure from the board) to drive organizations harder and harder, often to the detriment of long term objectives.

I would argue that drastically cutting inflation might help reduce income inequality over time.
Also interesting that as a kid born in 1980 at the start of the drug violence epidemic, we were allowed to roam as we pleased as long as we were home for dinner. Contrast that to today's vastly safer world, and kids are not allowed to walk the neighborhood unsupervised.
What kinds of activities have international events, though?

- academic conferences, but these are generally not relevant to the public, and if they are relevant to you, you're already attending them because you're an academic for the sake of your career

- premier fan events like San Diego Comic Con, but most people don't go there to make friends

- trade events like the Milan Fashion Week, but, again, you
already know if you belong there

- international sports competitions, if you're a world-class athlete

- technical conferences for programmers, but in my experience these have been an extraordinarily poor value for the money as a normal attendee

The ones that sort of make some sense to me are:

- if you're a bird-watcher, you could pay to go on an international bird-watching trip to the Galapagos or something

- if you're a young and rowdy party-goer, you could travel to one of those mega beach parties in the tropics

Idea for this post inspired by FutureTimeline.net website.

Here are few of mine;

1. Computer hardware will cost cheaper, because more people buying it and more people shifting to mobile devices.

2. There will be more virtual reality projects, seen how many people are stuck at home.

3. Some huge companies will split into smaller divisions.

Just a few that I personally think :)

Why force them to use it when email might be better?
It doesn't make much difference. It's still reprehensible to make it hard to cancel.

Let people cancel, confirm they've cancelled, and then ask for feedback. Put a feedback box on the confirmation page, imvite them to reply to the confirmation email. If you really must know, send a letter, and make one phone call (leave a message when they don't answer).

Anything else is abuse, and they're leaving you because you're abusive.

Oh to be clear, I think it's perfectly plausible (and even likely). You can boil the question down to "does smelling a female in heat lower impulse control in intact males", and, well, yeah, I can believe that without batting an eye. But it was a convenient place to make a larger point about the lack of good evidence in a lot of veterinary medicine, which I think is something we should talk more about (I'd levy the same critique against medicine for people, too!). Anyways, I probably should have been clearer in my original post, that my point was really: it seems completely plausible, but we need to be better about citing research in medicine and being explicit about corresponding confidence levels, and veterinary research is woefully under-funded.

I think my personal biggest complaint about the overwhelming prevalence of desexing in the US is that we're not really being honest with ourselves about why we're doing it. I would argue, based on my experience, (I realize the hypocrisy in using sociological anecdata immediately after complaining about medical anecdata), the vast majority of pet owners who desex their dogs do so out of convenience, and the vast majority of policy encouragements for it (eg: shelters requiring it or cities assessing 10x licensing fees for intact dogs) are done because most US dog owners aren't responsible enough to prevent unwanted pregnancies and have a horrible habit of abandoning unwanted litters. That's not to say that there aren't medical reasons; some of them are even on really solid footing (eg using spaying as a way to stop frequent painful false pregnancies), but I don't think most US dog owners are even aware of that being a thing, much less making medical decisions in response to it.

I think we are starting to see a discussion of sterilization vs desexing, which is great, but even so, as it stands today, spay/neuter is standard practice in the US. I almost never see an acknowledgement that, particularly for females, we've more or less mandated a very substantial, very invasive medical procedure, mostly just because dog owners in the US just don't want to deal with a particular part of canine biology. And I personally think that raises ethical concerns around treatment of animals.

I remember reading about this a few years ago here. If I remember correctly back then the main selling point was that it used succinct data structure and it was only the compression algo that was not open source - everything else was.

But now when I look at the new repo and the online doc there is no mention of succinct data struct anywhere.

Also, the benchmarks back then claimed 10x or more faster than RocksDB. Now the performance claim is much more modest.

Does that mean TerarkDB no longer uses succinct data struct? Or are you just open sourcing a lower-end version of the software without the secret sauce?

Can you talk about what makes TerarkDB faster than RocksDB?

Chemical, biological, nuclear, and anti-aircraft weapons are off-limits according to federal law. These rules have been enforced against people with terrorist intentions, but I would imagine any private citizen who believes they should be able to have them and can actually acquire them doesn't really feel the need to bother with fighting the law so long as they don't use them.
> In 1980s Los Angeles, a bank was robbed every hour of every day.

these are not the same statement. 'average ~1 per hour while banks are open' isn't the same as 'minimum 1 per hour', nor is it the same as 'every hour of every day'
It also depends on where you are.

This is surprising to me because of the use of quadrature amplitude modulation in wireless communication, which uses 2^n quadrature states. Of course these states encode groups of n bits, but the thing actually getting transmitted over the channel has many more than two states.

Elaborating on the “not in the same league” part, I would add that Tim Cook oversees a company and supply chain with revenue and profit far exceeding what Elon Musk has overseen to date.

If I need to do anything more than sending the message (on my own schedule - this part is important, I manage my personal life on nights and weekends) saying “hi, I’d like to cancel please” in order to actually have service cancelled and billing stopped, I’m likely to be frustrated and not give any feedback.

It's important to be reasonable about this, though. Email isn't secure, and anyone could send an email pretending to be you. If there are irreversible consequences to cancelling, such as deleting personal data held on the service, not only would it be irresponsible to accept an unverified email message as a cancellation request, it could actually be illegal in various places (under the GDPR, for example).

Not providing a straightforward cancellation option via a website where the customer's identity has already been confirmed using their normal credentials is a different matter entirely.
Bear in mind that Baremetrics removed self-serve account cancellation back in 2015. The founder admits in a blog post that it’s to reduce churn, and reduce churn it did, by 15%.

My biggest tip of advice for anyone dipping into CSS is to focus on _why_ CSS is behaving the way it is instead of memorizing the different properties and selectors. Some principles in CSS won't ever go away, and they will even explain how the newer features that "settled down" CSS work and make then even easier to use.

That's what Biden wants to do, terrible idea.

Removing favorable treatment of long term capital gains is also a terrible idea. Ideally, there should be 0% gains tax (and income tax), but people will settle for favorable treatment compared to income tax.

The superior model that has proven to work is Islam's Zakat. It's sort-of-but-not-really a wealth tax. 0% income tax, 0% gains tax, and only people who hold commodities over a certain threshold are taxed (meaning the poor are exempted). Gold and silver holdings for example are taxed at 2.5%, with a different percentage for cattle and produce.

As to your example, you won't pay a wealth tax on your car if you increase its value under Zakat. Now if you want to use it as a currency (start flipping cars) then it's different.

One thing I just remembered: Previous to Michael Vick's very public dog fighting bust in 2007 most dogs were destroyed after being seized from dog fighting(1). After Michael Vick's exposure organizations popped up to save these dogs. Now saving pit bulls is more popular than ever but not every shelter has the resources to do it.
