My Three Strikes Rule for Blogging
20% of kids ages 10-15 in 1900 were working. Many in horrible conditions and many probably died young as a result. That's a lot more than the foster system nowadays. Sending societies marginal people to an early death after extracting some productivity out of them was the historical solution to these problems as I see it.

Looking at the past with rose colored glasses is dangerous.

It's true that most American prisoners are not "nonviolent drug user" inmates. However, around 250,000 of them are [1]. That's still a huge chunk of human life.

As a side note, I think HN readers may get a lot out of reading [1], which is a pretty concise look at the American prison system and some of the facts and myths around it.

Issues can be tagged. So if there’s a sea of wishes just tag them to reduce confusion and let people know they are low priority.

Also, I don’t have much of an issue with closing low quality issues, but if a user writes up a good issue and it is stale due to low priority, or not enough resources, or whatnot that’s a different story.

I also find it really easy to sort high priority issues amongst 400 because there are comments, likes, and activity on issues. So there’s multiple ways for me to understand what it means.
So it's basically just a hosted version of the server-side parts for Stripe?

I assume you would have to put in your secret key or give full access to the Stripe account? Both of which sound like giant red flags.

Also what exactly is a request? And pricing, how does $5 for 250 make sense? $5 to send 250 text messages?
When >42% of Americans are obese, obesity cannot be viewed simply as a matter of personal responsibility. It is decidedly and firmly a public health and public policy issue, and as such arguments about fairness in vaccine distribution don’t hold much weight, in my view.
It’s too bad that all the other insane things he did will overshadow literally anything of value that he accomplished.
I would argue that any reasonable definition of visible includes being able to resolve features. In support of this, many dictionary definitions include words like 'accurate', 'clear' and 'obvious', while it's antonyms include 'unclear', 'indistinct' and 'obscured' and not just 'invisible'.

Are there good politically neutral alternatives to Stripe and Twilio? Asking for a friend.
Agreed. This is only a small first step towards some level of sanity but let’s hope that the Biden administration keeps going down that path.
>Honestly I don't know how she can be that confident that timing of the second dose doesn't matter, since this doesn't seem to have been tested with COVID vaccines. Perhaps it is a feature of vaccines in general?

Given that this is a completely novel vaccine, and there is zero clinical data to support that statement, there is literally no way she can know that for sure.

However, the Moderna vaccine confers an immunity approximately equivalent to convalescent COVID-19 patients within two weeks of the first dose, so she's probably fine.
The Future of Startups: Tech-Enabled, People Led
In theory.

In practice lightning channels require on-chain transactions to set up and tear down, and also have (had?) issues with nodes needing to be online for various reasons (including potentially losing the money to the counterparty), and IIRC there were potentially unsolvable routing issues too. They also require significant quantities of bitcoin to be locked into channels to make them work. It seems like a real hack.
I suspect the issue is the light bulb form factor. That shape requires that each fixture have its own (cheap) voltage regulator, and badly hampers their ability to release heat.

If you look at new residential light fixtures at your home improvement store, you’ll notice that they’re starting to shift over to built in LEDs. This allows them to use larger and better thermally regulated power supplies, and to provide better airflow over the individual LEDS.

I actually believe that the light bulb form factor is going to end up dying out in our lifetime.
LED light bulbs are pretty efficient at this point, so what I would really like to see is LED light bulbs that produce higher quality light.

Due to how they work, most LED lights have color rendering index[1] of 80 or below.
We have the technology, and there are some that have CRI above 95 within a reasonable price, but they are not so easy to find.
It would be nice if there were more LED lights with CRI above 95 especially in the 4000K to 5500K range.
I have one at home and the light is just beautiful.

The most powerful of these is only 3W, which it says replaces a 60W incandescent. Nowhere near powerful enough to replace anything that actually uses a lot of power and would be high-mounted. Maybe if you have a chandelier full of 60W incandescent bulbs, which since this is Dubai we're talking about, is actually possible.
If PoS actually works maybe not, but I'll believe it when I see it. Most alternatives to PoW I have seen replace it with some form of phantom centralization or are not secure.

My understanding is that PoS makes the hyperdeflationary problem worse by locking up a lot of currency, and also makes the wealth centralization problem worse. Eventually you'll end up with a few large stakers instead of a few large miners.

The thing that would really change my mind is if I saw cryptocurrencies being used a lot for useful commerce, not just gambling and money laundering. The closest I know is Monero which is used for black market commerce, but at least it's commerce. Trouble is that the bubbles actually chase away useful commerce by making the currency incredibly unstable vs. other currencies and stores of value.
Maybe there is a chance that insurance could be enabling malpractice? I'd have to get hard data on this to make a determination but I'd wager that most reputable medical professionals try to avoid malpractice regardless of country.

No, swapping two 1 bits works fine. Work it out more slowly, the article covered this and why it always works.

> developed to combat much of this.

Or some of these customs, traditions and institutions evolved to combat it through unconscious group selection. The tribes/towns/cities/countries/groups that had superior civic norms (superior defined as those norms which promote harmony, prosperity, in-group cooperation, etc) tended to attract immigrants, be capable of dominating geo-politically, etc, and thus those cultural values become dominant through this process of selection.

Also, while I think that explains things to a certain extent, it's just part of the picture. Culture also come from (i) self-interest, (ii) power asymmetries, and (iii) an unintended by-product of our evolutionary psychology/emotions/personalty traits such as jealousy/disgust sensitivity among others. For example jealousy mediating a desire for taxation (this has been studied by psychologists, it is one of the three common motives), or disgust sensitivity mediating a desire for borders and authoritarian leaders.
1/5 or 20% of people currently incarcerated are for non-violent drug use. This article tries to downplay it by reversing the statistic saying 4/5's aren't non-violent drug offenders. So about ~450k are incarcerated for non-violent drug possession in any given day.

I am pretty sure the providers and insurers know exactly what everyone is charging. It’s the patients that are being kept in the dark.
In American culture being fat is seen as a moral failing. Calling people out who already know they are overweight is offensive. You aren’t telling them something they don’t know. Likely they have already tried to lose weight and failed.

What I don’t understand is why you go from not trusting the state to trusting a different currency which the state you don’t trust could just ban outright at any time.

The Vulnerable Can Wait. Vaccinate the Covid Super-Spreaders First

Since you asked this question in two different locations, I'll give a 2nd answer here.

One way to construct a Reed Solomon code is to create a Vandemonde Matrix.

1 a^1 a^2 a^3 a^4 a^5 ...
1 a^2 a^4 a^6 a^8 a^10 ...
1 a^3 a^6 a^9 a^12 a^15 ...
...

All of the "1" values are from a^0.

As long as a^1, a^2, a^3... are distinct, then this matrix is invertible (aka: all rows / columns are linearly independent). In a GF(2^8) field, there are 2^8-1 distinct values (the values 0x01 through 0xFF), making a 255x255 matrix. The polynomial "x" (aka: 0x02) is often chosen to be the value of "a", but it can be any primitive element that loops around all 255 non-zero numbers and still work.

This Vandemonde Matrix has a very simple construction, but it is non-systematic (the data is "mangled" in encoded form, so we need to invert the matrix to decode). However, this non-systematic form is easier to see some patterns. Now lets take the 1st column:

1
1
1
1
1
...

Hmmm... look familiar? What happens when we multiply the data vector with this column?? It becomes a bit more obvious:

1
1
1
[d0 d1 d2 d3...] * 1
1
1
1
1
1

Remember, in Reed-Solomon, you perform operations over GF(2^blah). So all multiplications are GF-multiplications. But these are all multiplications by 1, so we can just ignore the complications of GF-multiplication entirely. (Even in GF(): a multiplication by 1 is just the identity).

To finish the matrix-multiply, we add everything together. But we do GF-addition (not regular addition). A GF-addition is also known as XOR. So the ultimate answer is:

d0 XOR d1 XOR d2 ...

Which so happens to be the first parity bit of the non-systematic Reed Solomon code. As such, we've proven the relationship between the "XOR trick" and Reed Solomon (Vandemonde construction).

------------

The hamming-distance between codes is 1. We can correct floor(1/2) errors (aka 0 errors) and 1 erasure. As such, this "all 1s matrix" is a 1-erasure punctured Reed Solomon code.
Are you sure that Bangladesh juvenile deliquency rates are all that much better then the ones in USA? Because looking at Bangladesh, they have pretty serious social problems in that area.

Strong norms in favor of marriage and strong taboos against divorce also however go with larger rates of domestic violence rates and no way out. That the perpetrators of those don't end up in jail does not make such society better behaved or less criminal/violent. Just tolerant of violence toward some people.
If you turn off the chain bitcoins still exist, but they are not fungible. What value do they have when they can't be traded?
Many of the laws and rules of societies in the past and most in the present, have always been about domination and control of women. Even women would join in on this, in order to subjugate younger females to societal order. It can be explained to survive hard times and trials, but is also mostly about injustice and inequality for different traits.

Though the females are regarded as assets, they're not allowed agency, freedom and inherent value. This is the history and hurt that is behind most of feminism of today, and there are still remnants in Western societies. Not because the laws and rules today are inherently discriminatory, but the cultural expression still inhibits life for half the population in many cases.

I'll leave it as an exercise for the reader what this may mean for BLM.
Yeah, I miss-read that. Thanks for pointing that out!
Nope. For lightning to scale, it would have to solve its routing problem, which it has absolutely zero prospect of ever doing. It is an open problem in science, and considered extremely difficult.
The alternative is often to not have the procedure at all.

You're making a lot of assumptions here that an out-of-country hospital would be of questionable quality and not have medical malpractice laws.

Just because other countries medical & legal systems are different than the US doesn't mean they are inferior.

Everyone has to start somewhere right?

Surely it's better to have a public transport system under utilized (so there are enough vehicles to meet demand) than over utilized (so everyone is crammed on like sardines)?

A quick Google search would show that oil accounts for less than 1% of Dubai's (which is not a country btw) GDP, which is less than the US on both a percentage and total monetary amount (adjusted for population) basis.

The idea is to look for prs that can be trivially resolved and for prs that can use more resources.
I think the price would be rather quadruple or quintuple for undetermined (multiple(?) decades average probably) lifetime with no or standard warranty and better energy efficiency.

I would still gladly buy it if I was sure that higher prices actually pay for more undervolted LEDs and is not a marketing gimmick to "instill sense of quality".

>> it's the mandated minimum for electronics in EU law AIUI.

It's such a common misconception I'm really shocked that EU has never made a better effort to clarify it.

EU does not enforce any warranty period by manufacturers. Zero. What it does enforce however, is the seller's responsibility for the product they sold. And this responsibility is at least 2 years(it's actually 6 years for most electronics and other products), but....it only covers manufacturing defects. That is the key word here. Any defects found in the first 6 months are presumed to be the result of manufacturing issues and the seller has to fix/replace the item for the buyer without asking for any proof of how the defect occured. But after 6 months, the responsibility shifts - it's the consumer who has to prove that the defect is a result of manufacturing problem. As I am sure you can appreciate, it's extremely difficult for most items. In theory you could call upon this law even after 5 years after buying a bulb and say that the bulb broke due to a manufacturing defects and the seller would have to replace it - but it's up to you to prove it.

You can produce oxygen from water, iron ore (O'Neill and other sci-fi writers somehow missed that astronauts brought back top quality iron ore from the moon,) stony rocks, etc.

To do it from water for instance you could use electricity to split up the H2O molecules; you could directly use the resulting O2 or you could use the H2 to reduce the iron ore back to H2O and thus recycle the H2. Maybe you get electricity from solar panels or a nuclear reactor.

You could burn this with cosmic hydrocarbons but you have only accomplished energy storage as opposed to an energy source. You are then competing with a sun that shines all the time and every other energy storage technology as well as nuclear fission, fusion, and decay.

The oxygen rich environment is the gift we get from plants here on Earth, ultimately they have stored a lot of "energy" in the atmosphere which we can tap.

Future wildcatters will see asteroid hydrocarbons as the material to make human bodies and cattle, everything from wood to plastics to pharmaceuticals -- every bit as much of a gold rush, but not a new energy source.

If you could make plastics from asteroid materials you could blow very large films and coat them with layers of metals and semiconductors and thus function as solar sails if not energy collectors -- these could sail to their destinations on their own power, say to be installed at the Earth-Sun L1 point to fight global warming.

Anyhow it took people a long time to get oxygen right. Cave men "mastered" fire but people couldn't make steel commercially until people understood that 80% of the atmosphere is inert stuff that goes along for the ride.

Ask HN: How do you manage user feedback or interview notes for a product?
I have seen people do this in a number of ways:

- Keep everything inside your head and unlock it whenever needed! That's superhuman stuff and definitely not the ideal.
- Take verbatim notes or transcribe conversations, store them in GDocs/Notion, and store insights in a spreadsheet (Airtable/Excel/Sheets).
- Use a software solution to manage it. This branches out into multiple directions depending on the role - PM, or UX researchers, for example.
- Build custom scripts and workflows

What has helped you make sense of user/customer feedback in the past?

- Gold plating everything to avoid getting sued.

- Inflated medical school costs

- the price of a huge bureaucracy for billing people, chasing them, disputing it, agreeing rates with insurers, renegotiating rates with insurers, applying the right discounts, billing a dozen different state and federal programs for various bits, those being disputed, managing all that etc.
Come to Brazil. The best Brazilian hospital (Albert Einstein Hospital in Sao Paulo) charges 1.7k USD for a C section (my son was born recently there), while the lowest I've found in that site is 2.6K USD (don't know about the quality) and median seems to be 8K USD. I bet the other procedures have similar price differences.

You can pay for the trip, get the best care (it is a really good, international level, hospital) and still have some loney left.
Funny :D In all seriousness though, if we detach these two claims:

Claim A: The man used the stolen ID to access additional areas besides the arrival area.

Claim B: The article claims that claim A is true.

Do you genuinely believe that claim B is true? If you say "yes", I will concede and accept that the article can be interpreted that way. Otherwise I will assume that there was some confusion between claim A and claim B.
>I've literally done all of the things you listed in the past month. Additionally, I'm at the gym 5x a week. If you're safe/responsible, there is absolutely no reason you can't do 99% of the things you want.

The reason I'm not doing those things isn't because I can't. I'm at practically zero risk now that I've been vaccinated. The reason I'm not doing it is because I don't want to be around people like you.

In 6 months from now, when there's no excuse to not be vaccinated, that will be a different story. But people going about normal life right now as if nothing were happening are the reason we're seeing 4,000 deaths a day in the US, and they are objectively bad human beings.

I am doing well for myself now. How I got here is pretty complicated. I can only attribute my ability to overcome these experiences to those who genuinely cared. These are the people who cared enough to help me succeed but also let me fail and deal with the consequences. In high school, I was a low C to D student. I slept in class. I refused to do homework. I thought the schools were only temporary, so therefore they did not matter. I only passed classes because I excelled at test taking and understood the material. I felt like it was all a game-- people, school, relationships. None of it mattered and all I had to do was find the right way to play. After foster care, I had a free ride (I was still in care), but failed out of college because I didn't see a point. I joined the military. This forced structure and discipline actually helped me. I understood this game and excelled. I used my experience in the military to get an entry level job in IT and continue to grow.
There are residual effects that I will always deal with. I have huge gaps in memory from when I was a kid- I don't remember much before age 11. I compartmentalize things too easily. I can be impatient with people. I dislike and distrust bureaucracies. I don't have enough patience for incompetence. I could go on, but I'm sure that's not why you're here :)

Your (absolutely valid) issue is with Proof-of-Work, not with Bitcoin or crypto in general.

Layer-2 solutions are coming up and Ethereum is showing excellent progress towards Proof-of-Stake. Combining these two, it will not only eliminate wasteful energy spending but will also get do hundreds of thousands of transactions.

When we get to those, will you stop crying for its demise or is there any other chip on your shoulder?
