A second-preimage attack is where you want to find m' where h(m) == h(m')... and you know m already. This is not very useful for password hashing; it would give you a second password that would also work to log into the account, but what's the point of that if you already know the first password? The relevant attack for password hashing is a regular preimage attack, where you don't know m (and it would be acceptable to find either m itself or any other string that hashes to the same value).
Our society is desperate for more social organizations in real life. Where are things like the rotary club, the elks lodge, the masons? Cultures that live in the real world? Businesses to support those groups? Fan groups seem to do okay, with conventions that make meeting up regularly a part of the culture. Board gamer groups do a decent job of mixing in the low range.

Its hard to find places in society where people go to meet other people. Bars are sort of them, but you tend to meet a lot of alcoholics. Hobby/activity groups are frequently too uncentered, culturally.
They are legally required to do this. The alternative was completely disabling iCloud in China. This only applies to Chinese users of course.
Cloning Server Admin from Mac OS X Server
GGPO Open Source
Seems like a bunch of these financial apps (like Personal Capital as well) are jumping on the cash management train. Seems like a good thing for their customers. Anyone have insight as to why this isn’t a good thing?
Yeah, they settled (the league wasn't found guilty). The lawyer for Kaepernick said "... the parties have decided to resolve the pending grievances. The resolution of this matter is subject to a confidentiality agreement so there will be no further comment by any party." So I'm not muddying the water, the water was never clear. There was never a clear public resolution.
(Again, I'm not saying they didn't do it.)
I mean, do you think literally everybody was doing string theory? There have always been plenty of theorists focused on more concrete things -- string theorists are not and have not been the majority.

Grad students entering even in the 90s knew they had to make a choice between concrete, more easily testable physics and a long-shot approach to quantum gravity. String theorists have stories of faculty going out of their way, back in grad school, to discourage them from going into it. (It wasn't just Glashow, either, it was most of the Harvard physics department.)

To say that string theory comprises all of theoretical physics is to uncritically accept the "me vs. the establishment" narrative some pop scientists put out. I think it does real damage inside the field, too, because it distorts the perspectives people have coming in.
This is a start on cloning the late great Server Admin app from Mac OS X Server into a web application. It's incomplete functionality-wise, but you are able to click through all of the setting panels for each service.

Right, as I said, there's nothing theoretically stopping this.

I just don't think that creating versions of humans that don't share any of the desires of humans is particularly interesting.

You might consider that the other approach would be to have a general AI that runs in software.

In some sense they are two paths towards the same goal.
It’s Not 1998. Welcome to the World of Online Insurance
The only example of actual increase of use in a particular feature is this one: https://miro.medium.com/max/2400/0*24guSnnmXQu2zi3n (the Google Translate example)

And in that it's not even just about icon vs icon + text, but two very different kind of icons... One is a snake (?) and the other one a pen.

Edit: Also, want to answer directly to "the increase in use of features ": that also doesn't necessary means it's good for the user. Maybe they don't actually have any use of it, and what they could see before on the main page, they now try to find.

Point being, designing UX after metrics is a bit pointless, as it doesn't show anything that you should really care about when solving someones problem.
This is an accounting trick, though. It works because people are willing to pay for a massage and not for whatever the person was doing. But to actually grow the economy, you have to continuously retask that person to ever more profitable activities.

You can also create growth by moving money in circles increasingly fast. Question is, how far we can push bullshit jobs before people get fed up with it? I'm not convinced that "forever" is the answer.
Goliath Season 3 on Amazon Prime and the Water Politics of California
Anyone who knows about Big Ag in CA and the yarn ball of water politics here knows what/who this is hinting at

https://ew.com/tv/2019/10/07/billy-bob-thornton-goliath-season-3-finale-spoilers/ WATER POLITICS IN CALIFORNIA.. I thought it would be a documentary..didn’t think it would end up on amazon prime as part of entertainment tv. [..] The siblings are at the center of a case in California’s Central Valley, where a drought brings to light the complexities of water ownership. What’s most depressing about the case, specifically, is the fact that this season was based on real events. Droughts have caused entire towns to sink due to over-pumping groundwater by farmers who need water for their crops and companies, which employ hundreds, if not thousands, of local residents.[..] “There are people who have said before that water will one day become as valuable as gold,” Thornton explains. “This is the story of the big farmer versus the little farmer, and it’s happening right now in our society and around the world. We’re looking at the rich versus the poor — even the middle class. Water is for everybody underneath the ground. There are no boundaries. So it’s legal to get water if you can drill for it and get it out of the ground. The problem is, the local farmer doesn’t have the money to drill for it. So if you have money, you can steal people’s water.”
Yes, the new Music app is literally just iTunes with the podcasts, audiobooks, and such taken out. It still retains all the Music-related scriptability.

At a glance, the new Podcasts app isn't scriptable but the TV app is.
Reminds of an episode of "Better of Ted" where the employer installed sensors that couldn't see black people. [0]. Funny in fiction, not so funny in real life.

Reminds me of a security issue we had on our linux servers at a former employer. Short of it is, one could run any command as another non-root user without having sudo access or knowing the user's password. rsh access was inadvertently left wide open on thousands of servers.

A coworker and I stumbled into this one morning when I was helping him figure out how to remotely invoke a linux command from a windows gui. I don't recall why we were using rsh as we'd normally ssh into our servers. As we sat there trying to figure out how to enter the password, we decided to just try and run the command w/o a password. We were shocked when it just worked - we were never prompted for a password. When I reported this to my director, he asked me how bad it was. I was like, watch this: I sent an email as the CEO to him saying "you're fired.". He immediately went to our infrastructure team to get it fixed. Fun times...
This is a pretty broad request. esp. not knowing you well enough to be able to tell what level you can handle/want. I suggest going to the local library and skimming the collections. If you have a half-decent local library they'll have a half decent collection in each of these fields.
I am really disappointed the text doesn't say hamburger.
Gmail and the consumer apps seem to be too data-driven to the point where the numbers are a self-fulling prophecy. Of course engagement goes up when confusion and bloat are added and users struggle to get things done.

You're right about the GCP console which is well designed (although still slower to load than AWS or Azure). Clearly they have different metrics there.
Rave/music scene is where a lot of people make friends too.
Yes, but I strongly prefer for focus to follow the mouse
that would be a pretty cool concept, but then you have to trust the banking authority, if all money is electronic, of course if you're not a criminal and if we don't have china-like social network in place it may be fine.

I think this could work, if all are taxed then all will feel more equal, the system could maybe funnel a little more $$ at the lower echelons of society than the upper's -- maybe have it simply raise networth's to some arbitrary minimum... make sure everyone has at least 1k in the bank at all times for instance to cover rent regardless of socio-economic factors.

We'd need to do away w/ cash though, or people could game the system by just withdrawing it all to appear 'poor'.
Agreed, they went nuclear without anticipating the world to fire back.
You didn't receive anything new. You already had the keys. There was simply a new client created to let you access these alternative coins.

If you own bitcoin private keys, you already own coins on an infinite number of hard forks. You're just lacking a client to access them.
I recommend you read the Accidental Scientist book. Its insane how many of human inventions were discovered out of luck. A super fast propulsion tech may be just around the corner and we don't know about it.

My point here is that you can never say never, its not a matter of belief its a matter of the future being unpredictable.

How about we just use more specific terms? China remains very much Leninist, and to a lesser extent Maoist; it has however mostly ceased to be Marxist. They kept the basic political forms but moved to a relatively liberal economic model.

There have been several previous HN discussions about him and his work: https://hn.algolia.com/?dateRange=all&page=0&prefix=false&qu.... You have to scroll back through the flurry from today of course.

I have a feeling that the name is a variant of the much more common "Goodnow", but can't remember where I got that notion.
In the USA, racism is biggest issue. In China, sovereignty is the biggest issue. Any companies who are doing business with China, they must have this in their minds.
My hunch is that for the "gig economy" to become anything more than worker exploitation, they will need to be restructured as commons-owned P2P networks where earnings and value are ~equally distributed.

It's absurd for 0.01% of popular, early-adopter creators to be making $millions on these platforms while 99.99% with the same output quality and skills struggle to earn enough to cover a fraction of their living costs.

But of course equal wealth distribution and commons ownership is a blindspot that the Silicon Valley sociopaths will never pursue.
Seems this whole concept is also obvious. UI remains as a problem simply because it's a problem pertaining and invented by nerds. People with common sense don't recognize the existence of UI.
I hadn’t seen that reporting.

What I meant was that it had never been approved, so the state never switched.

But you’re right, the reporting was that it was initially rejected, so I was wrong.
"Famously, UPS/FedEx are better than USPS."

This a red herring. First off, USPS is nearly as good as those, and those others don't have nearly the geographical breadth requirements of the USPS.
Valve has gotten lazy and incompetent from their rent seeking on the Steam monopoly. I will try to list some of the reasons.

The service goes down for 15-30 minutes every single Tuesday during peak hours. Can you imagine if your internet, TV, or cellphone did this?

There is also an absurd amount of unplanned downtime as well https://twitter.com/steamstatus there's a major outage every 2 months on average where you cannot even open Steam. The trading system is down A LOT. I don't know of any website like steamstatus that logs it, but it seems like it is down every other week. I also can't seem to trade more than 15 items at a time or the page will just hang, and this system is at least 6 years old already.

Before EA released Origin, there were no refunds on Steam.

I've emailed Valve exploits and they don't respond, not a single reply after years when 10 years ago they would have at least replied maybe 2-3 months later. They took HALF A YEAR to even acknowledge my exploit on hackerone.com and did not even fix it yet.

Their password system is also a huge sign of incompetence. They use RSA encryption on your plaintext password instead of just hashing the password. If someone hacked Valve, they will have your plaintext password. And if you're going to argue that someone can middleman an https server, I'm going to tell you the attacker could just serve up javascript to make the user send the plaintext password.

They also killed 3rd party servers in TF2 by putting them in a button at the bottom of the screen. It is similar to Apple putting all 3rd party apps in a link at the bottom of the app store. They also killed 3rd party servers in CS:GO by banning servers that were giving people default items and then being too lazy to ban servers that gave people items from their online store.

30% is standard? Why is it a standard and why can't it be lowered to 12% if Epic Games can do it? Why does Valve get to use the same standard as brick and mortar retailers when digital stores are way cheaper to maintain and more profitable because of forced online DRM and no reselling?

This is about all I care to ramble off right now, but there's more.

It is time for Valve to get a rude awakening from their comfortable monopoly. The Epic store is a good thing that will result in better service for consumers. And the only price you pay is to install another launcher that costs you nothing.

That too can be manipulated. Peaceful protesters could be infiltrated with violence quite easily and the message gets automatically diluted into something like.. the protesters want violence, the protesters are bad

Do you mean the recent tweet supporting the HK protesters? We know why that was deleted, because the Chinese government threatened the NBA. The NBA quickly caved, but it seems to have been too late: https://www.cnbc.com/2019/10/08/china-state-tv-suspends-nba-...
This shouldn’t be hard though. Execs shouldn’t think “we should maximize shareholder value while following the law”. Execs should think “what will I wish I had done when I’m 90”. Does it really hurt that much to tell your shareholders “we think it’s the right thing to stand up for democracy and human rights even if it means we are bennes from China and our profits are halved”.
you are too smart to be American :)
it's a classic submarine piece. we know these distributions have tails that are long as hell and the platforms themselves subject to massive first mover advantages.
You make a compelling point. The key is 'acceptable use'.

Acceptable use is cracking passwords in an investigation with just cause.

Acceptable use is a script to automate the checking of weak passwords, and notify users.

Unacceptable use is an admin browsing cracked passwords, without just cause.

I personally think acting on the information obtained afterwards is acceptable, but some would disagree.

Remember even in some courts, evidence obtained by police illegally cannot be submitted for trial.

I maintain these moral problems are hard ones.
> Is there a theoretical limit to the device's performance?

Yes.

Let the night-time equilibrium temperature be T_C (temperature_cold). Let the heat reservoir temperature be T_H (temperature_hot). The maximum theoretical efficiency is equal to 1 - T_C / T_H. This is from Carnot’s theorem and the 2nd law of thermodynamics.

The wasted energy is radiated off into space. You can calculate this with the Stefan–Boltzmann law. At 10°C we get 4.6 mW/m^2. (Edit: Whoops, bad arithmetic. Ignore these numbers. Do the math yourself.)

If your heat reservoir is 25°C and your cold temperature is 10°C then you have an efficiency of 5.0%. So you would generate 0.24 mW/m^2 at maximum theoretical efficiency.

You can even solve here for the optimum night-time temperature. Too cold and not enough heat is radiated. Too hot and the efficiency suffers. There is a maximum in the middle (but I am not going to do the math).

There are other interesting calculations I’m sure you can do to figure out maximum and minimum reservoir temperatures, but the challenge here is that you don’t want to harness sunlight to heat up your reservoir—you want to use existing heat that you have lying around.

Apparently, with our atmosphere we can achieve something like 40°C cooling in ideal conditions, and it is claimed that 60°C is possible. Back-of-the-envelope math suggests that you would achieve maximum theoretical power at around ~60°C difference.

With a reservoir temperature of 25°C my estimate is around 40W maximum power (with the correct arithmetic). You can get more power with a hotter reservoir.
Sure but what's wrong with something like:

I would argue that Typescript and React or Vue would have been a better solution for the customer. Yes, Elm might be better in some aspects, but I could name quite a few benefits for Typescript as well.

I think the technical reasoning is okayish, but from a business perspective I don't think the customer made a good choice.
Truth. I suspect an insignificant percent of internet comments are in the service of a few individuals special interests. That is to say, fake.
> Transporting people with current human lifetimes might not be practical. But brain scans on a computer? Or people in some form of cryogenic state or with life extension tech?

Or a generation ship. The most common approach proposed is a self-contained ecosystem that can grow the food and recycle the waste necessary to keep the ecosystem going and to support a breeding population of people, plants, and animals for the hundreds of years the trip takes.

That approach seems pretty far in the future. I don't think anyone has ever built a self-contained ecosystem that comes anywhere near close to being able to be self-sustaining for any great length of time.

Another approach might be possible that doesn't require a self-sustaining ecosystem, and seems much more in reach. The idea is to send most of the people as frozen eggs and sperm. Same for the animals that will be needed to establish a colony at the destination. Send the colony plants as frozen seeds.

The only already born people you would send is a small crew to operate the ship. They operate the ship for one generation, then make the next generation crew from some of the frozen eggs and sperm, train them, and hand off the ship to them. Repeat until the ship reaches the destination, and the final crew then uses the remaining frozen eggs and sperm to make and raise the colonists. Same for the animals and plants.

Because this approach only has a small crew on the ship at any time, it should be feasible to include their food upfront when the ship leaves. If you use food that has a large calorie/volume ratio, a lifetime supply of food for a person fits in a space that is probably smaller than you would guess.

For example, a typical protein bar is about 200 calories. If you need 3000 calories a day (space crewing is hard work!) for 100 years that works out to about 547500 bars. If each bar has a volume of 10 cm^3, you could store all that in a cube 176 cm on a side. Enough for a crew averaging 10 people at a time for 400 years would fit in the volume of a small single family house.
> I am surprised that McDonalds can offer you 50 cents off a burger without having to file a 1099.

A discount is not income. If they gave you a $0.50 gift card though, that's taxable income, and they should collect a W-9, and file a 1099 if the total of annual amounts adds up to $600 or more; as a recipient, you're required to include it in your income regardless of if the originator filed a 1099 or not.

Consider Eco's writing on Ur-Facism: http://www.interglacial.com/pub/text/Umberto_Eco_-_Eternal_F... and note that the apologia for the Chinese government by the owner of an NBA team focused heavily on point 8 (for example).

The CCP has long ago abandoned ideas of collective ownership; China has many very wealthy individuals whose wealth is private.
He slammed Microsoft store for being basic and incomplete, then released the epic store basic and incomplete.

It hasn't become concrete enough to make sharp, striking, correct predictions. It turns out the real world is extremely messy. Complexity theory can produce specific predictions ("disease spread will follow a power law with a critical exponent of...") but they won't be quantitatively correct. Or it can produce correct predictions ("airplanes increase disease spread because they increase the global network's connectivity") but they're generally obvious, and certainly don't require the full formalism of complexity theory to get.
My only hope is that we can extend this to biotech as well. The amount of IP theft and insane Chinese government subsidization of biotech that USA-based companies live off of is disturbing. They are so addicted to BS money and are so entrenched that these companies fear they can't back out. I say - Rip The Bandaid Off.
On HN, when there's a major story unfolding over time, we apply the "significant new information" test: https://hn.algolia.com/?dateRange=all&page=0&prefix=false&qu...

The idea is to have a new thread for each development that adds significant new information, and to downweight follow-ups and copycat stories that don't. In this way we prevent the front page from being flooded with repetitive stories and discussions (often low-quality ragey discussions, the internet being what it is), while making space for substantive new content when it arises. We came up with this after the Snowden deluge of 2013, when HN's front page was inundated with a lot of articles that didn't make this distinction, and many users—even ones who found the underlying story interesting—complained.

If we apply this test here, it's clear that "China says ‘stay tuned’" does not count as significant new information. On HN there's no harm in waiting until the next important thing happens, and in the meantime we can turn our attention to other interesting things.
