Have the greedy every changed the world, for the better?

Bitcoin adopters continue to religiously engage the same fraud that was adopted by initial promoters, peddling fantasies about decentralization, anonymity, transaction costs and taking on the global banking system. None of this is real, and on the last the slightest hint of adoption by the establishment send prices soaring and palpable excitement among supporters.

So if it has no utility, with supporters who lie, then where are the absurd valuations coming from? Bitcoin exists without relation to economics, demand, utility or value, and with negative externalities for efficiency and the environment making rational discussion redundant.

Why bother creating value to generate revenue, when you can print the revenue, literally. It's like a group of people get together to make IOU tokens and are convinced the world will one day accept their paper. Well if it has some utility the world may, but not simply because you want to gain something for nothing.
How Google and Facebook Could Save Net Neutrality
The amount of disinformation commonly expressed about vitamin D is quite amazing.

Bogus claims:

1. Spend a couple of minutes outside and you will be OK.

2. It is absorbed through the eyes.

3. Deficiencies are rare.

When in fact:

1. Does not apply at any time when your body is covered up mostly. Wear trousers and a T-shirt and you've cut yourself off severely already. Add weather with less sun, sunscreen, and/or more clothes and you've cut yourself off almost entirely unless you are outside for very long periods of time.

2. Fuck no.

3. They are extremely common even in sunny places. In the developed world a majority of people are.
Google shuts down Chrome ‘apps’ section on Mac and Windows
Even in fptp systems like the UK and the US correctly predicting the precise polling stations to infiltrate and compromise to stuff the required 1000-100000 ballots is tricky. And in the UK your whole plot would probably fail anyway - as random people and representatives of the other parties would be present observing you.

Shameless plug - I wrote my own self-hosting C toolchain (compiler + libc + assembler + linker): https://github.com/orodley/naive.

It was a really fun project, and I learned a lot from it.
In the U.S., it seems absurd to even consider Bitcoin (or any other cryptocurrency) for small day-to-day transactions like Steam purchases. Under the current IRS guidance, every sale or exchange of cryptocurrency is a taxable event.

That means that for every $10 game you bought with Bitcoin during the last summer sale, you now have to calculate the cost basis, capital gains, etc., of the BTC you used, and list it on a Form 8949 in April.
Crypto currencies are the first investment where everybody and your taxi driver gets to buy before the institutional investors.
I happen to have a gene mutation that makes methylation of B12 inefficient. I never did well in chemistry or biology for that matter, but my limited understanding is that methylation is necessary for it to be useful.

It turns out that you can buy methylated B12 called methylcobalamin. The more common form is cyanocobalamin, and is not very useful for people like myself.

That is my understanding, if anyone here knows better or more, please correct me.

Ask HN: What is your preferred 'between jobs' activity?
And by 'between jobs' I mean you already signed your next contract, sent your resignation, and now have some time to kill (days? weeks? months?) before the next job starts.
Milk costs more than a vitamin
tl;dr: we need wayyy more Vitamin D than previously recommended. ~13.3x more. Take supplements to reach 8000 IU/day for adults.

The amount of energy used for BTC is nothing compared to energy used for Internet.

It's equivalent to 0, compared to usage for heating and cooling.
I'd be interested to hear more on this. Is this warming uniform throughout the entire depth? Does the change in density impact the ocean uniformly or mostly on the top layer where the pressure is less?
This supports my lived experience. Found to be incredibly low in vitamin D, and diagnosed with autoimmune thyroiditis. Doctor said to supplement with 2000 IU being the max per day.

After seeing no improvement whatsoever in vitamin D levels, and after talking with others with the same issue, I self medicated to 10000 IU / day.

Lo and behold my vitamin D levels went back up and my auto-antibodies went back down.

If you replace "blockchain" with "database" and the application still makes sense, then you should not do "blockchain", at least for now.

Not all apps benefit by being on blockchain, on the contrary they are needlessly complicated.

There is a reason Netflix does not use torrents, centralized systems are efficient. Unless the application demands "trustless", no point touching it.
That's privacy (ie google collects your data), not security (some random hacker collects your data).

A bitcoin transaction does NOT use mining energy. Transaction rate and energy use are independent. The media always gets this wrong. It's like saying each bit on a CD-ROM "use fuel" when it's shipped on a mail truck.
Gold still holds value across centuries. A legionary from the Roman empire will be making $40k with his pay from back in the days. A key to a hash will be worthless in the future, specially when SHA2 will get broken.
Define "makes the problem worse".

More lanes, in networking terms, improves throughput but doesn't improve latency.

More lanes moves more cars. That's fairly straightforward.

More lanes doesn't improve the time of an individual commute on the road or cut down on congestion of the road.

People have a fixed annoyance level, and congestion will increase until that annoyance level equilibrium is reached again.

The only time more lanes genuinely improves things is when the extra lanes suddenly means that the road now has more capacity than required to carry the traffic level it sees.

Normally, the cost required to add that many lanes is sufficiently prohibitive that such a situation almost never occurs.
The Dark Side of Artificial Intelligence
Because of impaired kidney function, I get my vitamin D levels monitored every month. Yes supplements can take 2-3 months to increase the levels. The sun actually works pretty good if you can stay outside 15 minutes in noon sun. But that's difficult in the winter months.
> Because "higher level people" are the ones who make the decisions to do things like this

That's a big assumption, IMO. It's quite a huge assumption on how high it actually goes.

> and they nearly always get away with it.

Based on on your presumption of guilt?

I don't support presuming the guiltiness of top level executives that had no idea "because they should have known." Its reminiscent of a witch hunt.
The energy still becomes waste heat when used on Earth.

The Monadic logging concept explained (in JavaScript)
Thanks for this added information. I discovered the same thing, with another family member where Methylcobalamin worked wonders and Cyanocobalamin didn't.

One thing I would add is that Methylcobalamin needs to be injected to work best. If people do not have your gene mutation, they are better off taking Cyanocobalamin.

PS: Whenever someone in family has major health issue which no one can get handle on - they reach out to me. My lifelong dream has been to cure Cancer using AI. Just started working on that.
If one wants to short the CBOE/CME futures and also be hedged, he'd need to go long on spot price. That will only increase its price.
Uber hast been created to bet on a billion dollar jackpot so I think they should respect people who are betting on smaller jackpots. I don't understand why the little guy is supposed to ask only for his labor rate while the company is shooting for the really big money.
True, cyanocobalamin for people like you won't work.

Although consuming just methylcobalamin leaves out adenosylcobalamin.
Never heard about NiceHash before, but this story is currently being reported by Slovenian national media and NiceHash is presented as a Slovenian company.

Fair point but doesn't this run directly counter to the trend of startups leveraging an increasing amount of open source code?
This is a very caucasian centric viewpoint.

The fact is that if you live in higher latitudes and have dark skin, you physically cannot absorb enough vitamin D from sunlight during the winter months. While it is physically possible during the summer, it is not practical to spend hours sunbathing.
You’ve watched 300 movies at AMC in the past 3.5 years??? Or are you playing some arbitrage here
I just want to say the b complexes are indeed super important, but recent studies indicate a potential link between overly high dosage and some types of cancers, particularly in men. So be wary of overdoing it with those 3000% dv supplements.
How will you get readers if you are sending it only by email. Unless you are good at email marketing
Another big challenge in winter months is that people are so covered with warm clothes, that even going out in Sun doesn't help much.
I’m sorry, but all of this comment is incorrect.

1. Vulnerabilities in the individual websites of specific companies have typically little to no salable value on a “open market”, black or otherwise.

2. People who manage bug bounty programs know this, and those programs are not designed to compete with a shadowy underworld. They’re just an incentive for reporting security vulnerabilities.

3. Apple’s security vulnerabilities actually do compete with a market for the sale of exploits, but this is because vulnerabilities in iOS or macOS represent vulnerabilities in deployed operating systems and software for which they are not the sole arbiter of an update decision.

> Bug bounty programs are often probably underpaying compared to what something would be worth on the black market, but clean money is worth lots more than dirty money with a prison risk

I say the following as someone who has: 1) managed a bug bounty internally as a security engineer, 2) managed bug hounties as a consultant for various tech companies of various sizes, 3) reported security vulnerabilities in bounty programs for companies you’ve heard of, 4) spoken professionally with engineers at tiny, small, medium and large companies running programs and 5) sold vulnerabilities for various reasons:

Bug bounty programs are emphatically not underpaying relative to a black market. Black market exchanges exist for vulnerabilities which impact operating systems, widely used open source software and languages. A key component of the value of a vulnerability is its half-life - that is to say, how long it can be expected to be useful. A vulnerability in Ubuntu has a half-life of years, perhaps decades. A vulnerability in Uber’s web applications has a half-life of one week. In 15 years, you will reliably find servers on the internet chugging along with a horribly misconfigured, vulnerable version of Windows or Debian and an open service written in Python 2.7. In contrast, Uber’s web applications will scarcely look the same in 15 years, and the company can deploy a hotfix to the entire landscape of the vulnerability (their centralized servers) in 24 hours.

Can you conconct a scenario in which a hypothetical sabateur manages to weaponize and capitalize on an exploit in Facebook Ads Manager, or some random Uber server with sensitive data, within a week? Sure, but it’s contrived. The risk/reward ratio just isn’t really there.

I’ve continually crusaded against what you’re claiming on HN for literally years now. It’s simply not true. I don’t mean to be harsh on you in particular, but the confident repetition of incorrect claims becomes frustrating.
A lack of urban planning.

* Not enough family sized units in the city (drive down cost with supply).
* Insufficient quality of life in building codes. (Noise, smell, clean air, green spaces)
* Lack of vertical density;
This is begging for Cave of Steel like results complete with indoor parks and atriums.
You'd think sunny places would fare better - however after moving to Key West from Montreal I discovered people here spent a lot of effort avoiding the sun (skin cancer is big down here).

You don't know what you are talking about.

I use Bitcoin to transact with my brother overseas. It's decentralized. It works.

Yes there is an absurd bubble going on. But bubbles are expected with revolutionary technologies (18th century train companies, 19th century car companies, 1990s dot com bubble...)
Breaking news: Indian scientists find effective way to detect and kill virus
I've read varying reports of how much sun you need to generate a day's supply of vitamin D, but rarely do they mention how much skin needs to be exposed.

Face only? Face and arms? Entire upper body? Entire body?

Is there some online resource for this with time of year and latitude corrections? I imagine there's quite a difference between vitamin D production in noon sun in Fairbanks Alaska versus Miami Florida.
You would need to drink over 4 gallons of fortified milk per day to get the recommended 8000 IU. Milk just isn't fortified enough, because the current daily recommendations are so low.

I wonder if glass windows would block out the benefits?
Anecdotally, I had this discussion with a cardiovascular interventionist specialist about seven or eight years ago when I was managing a team of cardio theatre orderlies in a private hospital. He made the comment, "mark my words, in about five to ten years time there will be a major scare about needing to absorb more vitamin D".

His opinion was that the increase in sunscreen usage and the push to avoid skin cancer by staying covered up was likely to blame. I find it interesting when articles such as this pop up, because it directly reflects his concerns from those years ago.

For reference, this was the late Dr Geoffrey Mews (who I only just realised has passed on while I was looking for a reference to post. That's made me a bit sad now)
You can take methylcobalamin sublingually. Absorption is fine, according to my blood results.
Zbox author here. Woo, I didn't even prepared for a HN debut. :-) Anyway thanks for your comments.

One of the major goals of this project is to keep app files private, which means exposure surface must be as minimal as possible. To this end, it intentionally does not support mount/FUSE or other mechanisms which can 'share' access across processes. Zbox doesn't allow multiple processes access, even those processes are under same user account.

For your question why not make it an embeddable key-value store. I think, IMHO, file store is more generic. We have VERY long history using file system, it is the base of every OS, it has solid API, every language provide similar access interface, everybody familiar with how to talk with file system. For Zbox it also provides similar API to Rust's file system API, that will make most developers much easier to adopt it.
I've never read a recommendation for 100 nmol/L before. Previous numbers were around 50-70 nmol/L. So this seems noteworthy.

There also appears to be some evidence to support Vitamin K2 as a complement to Vitamin D supplementation, in order to reduce or prevent cardiovascular calcification.
This absolutely awesome!

I'm very excited for AntidoteDB, for its use cases but also for the underlying, pioneering work you're doing on CRDTs. Thank you for doing it! <3
Simplicity is the answer without the question.

It's difficult to determine whether there is a selection bias. Many people who smoke, take Vitamin B12 supplements.

Anyways it's a good idea to not overdo these supplements.
This is a good article on the matter with more in depth information: http://www.solar-facts-and-advice.com/vitamin-D-from-the-sun...

As one of the sibling commenter said, it very much depends on your skin shade and the location on Earth.
Excellent article. Thanks for posting.

This is one of the reasons I hate dermatologist's panic against sun exposure. Vitamin D deficiency kills way more people than skin cancer.
But there is a cost for each bit. It's amortized. Because at some point you need a second cd, which increases fuel a tiny bit, and lowers the amirtized cost per bit. At some point you need a bigger truck and then a second truck, suddenly the cost jumps up a whole lot.

Transactions are limited in number. Each transaction costs.

The piece of paper in my pocket is backed by the full faith and credit of the United States, an institution that has kept that faith for 241 years and that has the faith of the world. The planet is absolutely full of greater fools that have, do, and will continue to value the dollar.

That "fake coin" in my electronic wallet is backed by algorithms. The greater fools giving it value are and have been, as far as I can see, excited mostly by profiting on the speculation of it. Who actually uses bitcoin outside of trying to profit from the bubble or just for the novelty of using it?

The dollar is backed by the wealth and economy of the nation, the coin exclusively by greater fools and it's rarity.
Has anyone had experience ordering blood work (e.g. the vitamin d 25 hydroxy test) without visiting a doctor? I've seen very few references to the set of sites that pop up first online [0, 1, 2, 3] when I've gone looking for reviews in the past. Any suggestions? I'm in CA.

Sure, if by "Browsers" you mean "the browser made by the Ad Network company that has a vested interest in people using web based computing for everything they do, regardless of security concerns".

My browser (Safari) shows me the domain I'm connected to for DV, and the verified organisation name for EV, and the certificate details are a click away in either case. If Chrome doesn't provide some of that information, thats a fault against Chrome, not the concept of Certificates.

BTC is worth what it is thanks to massive manipulation under the hood just like the last run up. The music is gonna stop sometime. Almost every exchange is sketchy and you have no promise that anybody is playing fair....

Bitcoin is pure, 100% hype and will not replace any of our financial institutions.
Yep, they are and also the best form. Extremely unstable in capsules and oral supplements though.

Methylcobalamin isn't very effective orally. However someone with a gene mutation doesn't have any choices.
