You misconstrue the algorithm, difficulty only increases when hash power increases to maintain a 10 min blocktime. Difficulty can decrease too.
He does. Early versions allowed you to spend anybody else's money by using this script as "signature".

Spending money involves prepending the input script to the output script, then executing and checking the result.

Normally the output script is something like "[pubkey] OP_CHECKSIG" (for the old P2PK), and the only input script to cause the combination to succeed would be the valid signature, such that "[sig] [pubkey] OP_CHECKSIG" succeeds.

With "OP_TRUE OP_RETURN" instead of [sig] it would also succeed as OP_RETURN would stop execution.

This was fixed by ensuring OP_RETURN stops execution AND fails the script.

Ask HN: Independent App developers – do you own an Android device and iPhone?
Probably a dumb question, but I'm just getting started in app development and wondering how to properly test things. I own an iPhone but don't have an Android device in my house. And even if I got one, there are so MANY different types out there...

How do you properly test an app if you can't afford to own a hundred devices? Simulate & pray?
I now flagged it, 21 upvotes, and it went into flagged mode again. No idea how many flags cancel out upvotes or how the algorithm really works.

In my opinion that's entertainment news, not hackernews material. https://news.ycombinator.com/newsguidelines.html "Off-Topic: Most stories about politics, or crime, or sports, unless they're evidence of some interesting new phenomenon."

Some topics, scandals, even catastrophes are usually completely ignored on HN. The idea is that other websites, the main stream media and large newspaper, sufficiently cover it.

I'm not arguing against the story itself. I've read it in the newspaper this morning. Just my expectation when opening HN is not to see/discuss a celebrity paying off a rape victim, regardless the circumstances that led to act. Actually I'm surprised the Weinstein story made the frontpage.
A City Shaped by Steam (New York)
Telling the Truth About Defects in Technology Should Never Be Illegal
When I was a kid, 10% was fairly normal.

Last time I went to a restaurant in the US, I got scolded because I refused to tip when the waitress brought my food out cold and never once gave me a refill. I'm apparently "supposed" to tip 25% these days.

When people do their job, I'm okay with tipping. But I'm not OK with tipping based on the price of the meal. A person who works at a $70/plate restaurant and keeps filling my glass of water up with ice before I can finish it, making it unbearably cold, really isn't doing anything better than an overworked waiter in a $7/plate dirty hole in the wall shack. The skills don't differ (and I'm honestly often impressed with how skill-less waiters are at high-end American restaurants--they're worse than typical servers in any other country) and they're not the ones making the meals.

Just bring me a drink that's at least 90% drink and not 90% ice, bring my food out before it's cold, and get me a refill within a few minutes of running out and I have no trouble dropping $10 or $20--the price of the meal doesn't factor into that. Fail to do that, and you're getting nothing--I don't care how expensive the meal is that the chef prepared, but you had zero involvement so you're not entitled to that cash.

But I'm glad I'm not living in a place with a toxic restaurant culture, so it's not my problem anymore. :)

Not really.

The problem is that with twice as many sigops, you would also have to hash ~twice as much for each sigop. Hence O(n*m). A problem known "quadratic hashing".

This is solved by using a different way to hash the signatures that doesn't require full recalculation on each input.

In Bitcoin Cash it is fixed for all transactions; in Bitcoin it is only fixed for SegWit transactions so an attacker could still do this, by not using segwits.

It is very likely because the connecting bike infrastructure is either not very good or completely lacking.

You can't make good bike infrastructure by simply painting a few bike lanes here and there that "hug the road for a few KMs". You need to look at a bigger picture and make bike-friendly connections between popular hotspots.

On top of this, there's apparently still a perception in the US that bikes are either for kids or purely for exercise, they're not really thought of as everyday transportation. Everyone with an interest in improving city traffic should come visit Amsterdam or Copenhagen. See how infrastructure with a primary focus on bicycles and public transit works, and which design decisions have helped shape city traffic.

An issue further compounding this is the insistence that bikes are completely the same as cars, and should follow the exact same rules. This leads to extremely dangerous lane changes and left turns, because cyclists are expected to use the car's left turn lanes. This danger can be easily mitigated by requiring cyclists to make hook turns[¤] instead. We do this in most European countries, and it's significantly safer for everyone involved.

"performing studies with fifteen people"

The study only shows that blood flow to your brain drops when you are sitting for a long period of time. So I think 15 people is a huge sample in this case.

The study doesn't even has any conclusions. So I think 15 people is fine.

The next step could be gathering data from thousands of people to check weather this causes brain damage in any form. But that's not what the study was about. Only the title of the article suggests this.

That would be the Killing in Self-Defense[0] trope, mixed with a dash of "Thou Shalt Not Kill[1]". There are many ways to pull this kind of scene of, having the hero kill in self defense preserves the hero's status as "doesn't murder". You can have self-disposing villains[2] so the hero even preserves "doesn't kill" or alternatively you go for "He Who Fights Monsters"[3] (if the hero is corrupted)/"If You Kill Him You Will Be Just Like Him"[4] (corrupted and/or breaking their no-kill rule makes them the villain).

I probably understand both sides of the debate over chiropractic better than most, so I'll try to answer.

Chiropractic has become highly controversial for two main reasons.

The first is that it claims its treatments (muscular-skeletal adjustments) can bring about healing of a wide array of illnesses in the body beyond just back pain. The basis of the claim is that by straightening the muscular-skeletal structure, they remove blockages in blood vessels and nerves, and the resulting improvement in blood flow and nerve signalling leads to improvements in organ function, immunity, tissue healing/growth, cognition, etc.

The second is that one of its major treatments, the vigorous "neck-cracking" adjustment of the cervical spine, can occasionally cause a rupture to the main artery to the brain, leading to haemorrhage that can result in severe disability or mortality.

Skeptics will argue that it's impossible that muscular-skeletal adjustments can heal other illnesses in the body. I gather some of them will dispute that muscular-skeletal misalignments can cause significant blockages in nerves and blood vessels, whereas others will deny that removing said blockages can lead to other health improvements. For what its worth, it seems the linked article lends some credence to the notion that muscular-skeletal alignment can influence other aspects of a person's health.

Regarding the neck adjustment risk issue: opponents of chiro will concede that ruptures are very infrequent (estimates vary from once per several hundred thousand adjustments, to once per a few millon), but conclude that given the absence of benefits, it's not a risk worth taking.

My own experience with chiro is mixed. I have used it a lot in the past, and I no longer do. I do believe that in some cases, serious misalignments in the muscular-skeletal system can cause nerve and blood-vessel blockages and lead to other impairments in the body. However I haven't found chiro to be the best way to relieve the pain or misalignments I'd been carrying; I've recently had better success with osteopathy and myotherapy (a form of massage focusing on the myofascial system).

I have found some chiropractors (more than half those I've seen) to be over-confident about the benefits of their treatments. But then a handful of chiropractors (practitioners of a particular mind+body healing technique) have been the most valuable practitioners I've seen, of any kind.

I have had neck adjustments and never had a problem, but I wouldn't encourage others to do it or allow it do be done to my children, and these days I avoid having it done, preferring to focus on relieving muscle tension through myotherapy.

#No Fake News: US Refusal to Rebuild Syria Designed to Impede
Looks like they use Transcranial Alternating Current Stimulation (tACS).

The military has been doing tDCS (direct current) experiments for a while for increased learning & performance.

I had a friend who used to swear by tDCS and did it very frequently. He attributed all kinds of mood & cognition improvements to it, including substantially reduced need for sleep, improved eyesight (he was born partially blind), etc. He also complained about migraines a lot and liked to experiment with all kinds of supplements, so YMMV.

Tried tDCS myself a handful of times, not for improved learning but for improved focus. If applied correctly it definitely has an effect that I'd consider better / stronger than a cup of coffee. I wouldn't feel comfortable doing it regularly though.

There's a subreddit that used to be pretty active:

[comic]What If Ubuntu, Archlinux, Debian, Devuan, Centos and Openbsd Had a Race?
You may want to re-read the guidelines. Especially the bit about emailing the mods.
I blame Google and Chrome. Because Google continues to push for marketshare. If their devs were good devs they would strive for a balanced marketshare, not domination.

This is obviously not what Google is doing, therefore I blame them just as much as the web devs.

If you want an example, though recently fixed after I sent of a very angry complaint, the ELSTER tax system in Germany didn't work if you had a certificate login on Firefox+Linux but it worked on Chrome+Linux.

Another example is some of google's own websites, which break U2F authentication at times, though it might have been fixed in the meantime.

Why not? Does the average person earn the total movie industry more money in any other way?

Having 100 million subs (Netflix has 120 million atm) would then give you 1 billion per month -- which sounds decent enough to support a comprehensive movie archive, especially since most of it would be a long tail of movies that make tiny or no profit today and that would cost next to nothing to store for the occasional user.

And for the popular titles, you could even opt for a distributed (e.g. bittorrent like) serving, to further lower your costs.
If they're running that business, they are either paying people who can tell them the dependencies (if not, those people are being paid too much), or they are responsible for the code themselves (small co. or early startup), and should already know, or with small effort be able to identify all the dependencies whenever necessary. Anything else would be irresponsible.

If they're not running that business and have enough access to the code to be able to use this service, they're probably a developer who again should be able to know about the dependencies.

Or perhaps they're in a different position, and only want to know about this for curiosity's sake - in which case, I guess this could be useful. But still, you should be able to ask about this in-house.

And as for the "layers" argument - if there are too many layers of dependencies to keep track of, something is very, very wrong with the technology you are using. (And yes, I do consider modern web tech completely insane.)
In Python 4.0 (the one after 3.9), and in Python 3.7 now with "from __future__ import annotations", annotations are parsed but their interpolation is delayed. So you can literally have "var: 0 < var < 3" (annotation is not a string!) in your code and make it work as you wish.
A bit off topic, I find it a bit ironic that you bring up Churchill in a discussion about famine, given that he was directly responsible for the starvation of millions of Indians.

Same in German. A lot of people say "Das macht Sinn", which is a literal translation of "That makes sense." But "Sinn machen" is implausible in German because "machen" is more like "to manufacture".

You need to work on focusing so that you can take breaks and go right back to work. There are many ways to improve that from simply 'do it' to using a certain playlist. I started with the playlist and have now use a combination of that with 'do it' discipline.

How would that be different from the regular Microsoft Ecosystem?

I can spin up a quick testserver using Windows Server, running an IIS webserver and Microsoft SQL Server, with my software stack written in C#, programmed in Visual Studio. It covers pretty much everything I could need, and involves ordering à la carte instead of negotiations.

Obviously it costs more and unless I spin up a cloud server I can't "just spin up a server" without making sure I have enough licences etc. But AWS/GCP/Azure solve that mostly.

Also, past the LaserJet 5, their printers started taking a nosedive in quality. In my own experience at work, the 1000 didn't last long before it started spewing toner all over the page, and the 4550N, a gigantic color laser with extremely expensive consumables, did likewise.

Don't get me started on their inkjets. Nothing like an all-in-one that won't even let you SCAN when it decides to "expire" a costly printhead.

This book must be a mirror where different people see different things.

For me, morally, it was a tale about how some deeds are so horrible, that no matter what your motivations or circumstances were they can never be good. You saved humanity? Doesn't matter if you exterminated entire intelligent species for that. You were decieved to do that? Still doesn't matter.

It resonated with me, an atheist, very strongly that some evils while might be forgiven by some people for some time, they can never be "absolved".

For me on personal level such unabsolvable deed is killing. By extension I think that army won't be moral untill each soldier comming back from the war is ready to be tried and sentenced for each life he took. We are probably closer to singuarity than to morality defined like that.
What do programmers *really* do?
Agreed. It’s classic “Innovator’s Dilemma” stuff right up until the Fiorina era which was just wanton destruction for the sake of being seen to do something but having no idea what.
The experiment was criticized (convincingly) in "The Anatomy of Human Destructiveness" by Erich Fromm.

Even without bringing any hitherto unknown evidence in, it's not difficult to see its various flaws.
It could be viewed as egoism though, when at specific angles. What win is? That everyone chit-chats instead of learning on a regular basis? Is your teacher a foe? You make friends of who?

It is hard to define a long-term win. In my story above we two refused our position not because we didn't like to create homeworks. In fact, what we did wasn't much different from school books; we even categorized tasks and watched that they weren't too hard, leaving only a couple of pieces that required some thinking. What we didn't like was scoring our friends, non-friends and whatever these relationships were back then. But still I think that seeing how they learn and provide a feedback is, well, a slightly better than just throwing books at them and wait for a success. Our class actually knew some physics as a result. It is a social price that was questionable, not a learning process. Despite being viewed as a 'good guy', now I don't have strong relationships with any of my then buddies anyway. Sum up? Our teacher could be not as unthoughtful as it seemed.

tl;dr while everyone is on their own, someone has to think of the group as a whole. It doesn't mean you all end up in a better place, but at least you tried and had an opinion instead of a denial. People are pretty forgiving if your intents are good-natured.
