Like many classmates getting our PhDs, I considered my field, physics, the most fundamental of all the sciences, joking that we could derive the rest. That was the 90s. In today's world, I consider the most important role of anyone who understands nature to help spread understanding of our environmental situation, though I consider the most important task now to lead.

As far as science books, I'm going to share three titles I read this year I highly recommend, though they're about ten years old

- Countdown, by Alan Weisman, for covering (over)population, especially for sharing examples of nations that lowered birthrates without coercion or legislation, yielding greater happiness and prosperity.

- The World Without Us, by Alan Weisman, for illustrating our effect on the world colorfully and inspirationally.

- The Once and Future World, by J.B. MacKinnon, for illustrating how much more nature there used to be, how much we've lost, and how much more we stand to lose.

- Limits to Growth, the 30-year Update, almost 20 years old, but the most thorough treatment of us and our environment. Critics criticize it, but all the criticism I've seen actually criticizes straw men and other misunderstandings (if you know of meaningful criticism please let me know). Meanwhile, this paper https://sustainable.unimelb.edu.au/publications/research-pap... from five years ago shows their "business as usual" model continues to be unreasonably accurate nearly 50 years later, suggesting to me LtG's relevance and poignancy.

You can't go wrong reading any of these books, though I'd start with Limits to Growth.
David May was my computer architecture professor.
Well, that may have happened if you read between the lines. The USB drive went missing and Monica joined the NSA. Or Jin-Yang.

Not that I have some kind of poser tech bro gush for the show... okay maybe.
I was enjoying the irony of reading the article on safari only to have it cut off so they can ask me for my personal information to track me.
Demand has decreased. The curve of constant demand with decreased supply pushes the price higher.
Shopping for a Boy? Give Him a Book About a Girl
I don't understand the argument this article is making. It goes from establishing that the cost of child care has increased much faster than other goods/services, to advocating that the government pay for it. Where's the connection? Simply moving the costs from new parents to the US tax-base won't do anything to address the underlying causes of the high costs.

It seems to me that we need solutions to address the high cost in any case, and the question of whether the government should be more involved is an orthogonal concern.

Unless the argument is that there's not an effective way to control the costs, so the government should help pay for it to not overly burden new parents. But, I didn't see that point explicitly made in the article.

WADA is not an American organization. How does Canada figure into your conspiracy theory (literally, your theory about a conspiracy)?
Pricing on targeted ads is linked to confidence that a person will perform an action (buy, sign-up, etc). This is a function of the "richness" of data collected -- does the data about you contain demographics, engagement, behavior, so forth.

So a shoe company may pay a lot for a "male/18-35/basketball-fan/shoe-blog-reader". But Safari does not easily allow for that richness of data to be collected, so the price is low.

It would depend on the time to get a service to respond when scaled to zero. Otherwise it seems to be twice the cost of fargate with AWS, if you need to have it running all the time to get reasonable response times.

My understanding is that a gain or loss in that currency is recognized upon spending/trading it.

Quick search brought me to https://thismatter.com/money/tax/foreign-currency-transactio... which agrees with that.

Like use tax, I suspect it is often just neglected.
Lightning network comes up just about every discussion involving bitcoin transactions, but because it requires the bitcoin network to make confirmations, Lightning only scales with the number of transactions, not users. This is still a problem.

Example of the problem:

* For 2 users to make 10,000,000 transactions between each other, it would take 10 minutes on the lightning network.

* For 10,000,000 users to make just 2 transactions between each other, it would take 46 days on the lightning network.

This means that if the entire state of Georgia used Lightning Network as a payment system, people wouldn't even be able to pay their monthly rent on time. Lightning Network is an over-engineered solution to a Bitcoin problem, which is why nobody is seriously adopting it.
No one is claiming that paying that is easy for everyone, merely that taking care of someone for 9 hours a day, including meals, for $40/day is actually ridiculously cheap. I can't think of many (any?) services I could pay for that would cost a mere $4/hr for labor+materials.
I didn't know he got tenure at Harvard! Last I checked he was still as MS Research. That's awesome.

Art.

If you get into the whole don't use resources, paying money for products that have a lot of artistic thought put into them makes sense. Artistic thought uses nothing from the planet, the person has to eat anyway.

I personally have no issue with using resources, but if someone else wants to spend it on art, cool, I still get to view it.
There are other business models for open-source projects than the freemium/enterprise model mentioned in this article. For example, offering service and support can sustain an open-source company. Here is a broader list:

Normal usage has already done this. New renewable energy sources are cheaper than new fossil fuel sources. Fossil fuels exist mainly today because they have already been set up but mostly for political reasons. Many political parties have built their personal brand around fossil fuels and will continue to use them even when it is illogical.
Supply and demand have stayed the same in quantity, but the quality of both has dropped severely. It's the same equilibrium but at a much lower price point.

My favorite one (that probably will never come back) is the concept of ternary computer on a balanced ternary number system.

In hindsight it is a much better way to encode signs for both integers and floating points.
I guess the choice thus comes down to how much potential benefits may be possible, versus what software actually needs? (I can see first-hand we don't need more single-thread performance in so many use cases)

I just have no idea "how good it can get", compared to what we have now. Is there an alternative world where CPUs vastly outperform ours in performance/power using the same materials? But more importantly how much can "vastly" be?
Gender and Our Brains cites studies and data that are selectively chosen to support a predetermined conclusion.

As to why:

> After almost 20 years of hearing the same invalid arguments (like Bill Murray in “Groundhog Day” waking up to the same song every day), I have come to see clearly that the real problem is a deeply ingrained, implicit, very powerful yet 100 percent false assumption that if women and men are to be considered “equal,” they have to be “the same.” Conversely, the argument goes, if neuroscience shows that women and men are not the same on average, then it somehow shows that they are not equal on average. Although this assumption is false, it still creates fear of sex differences in those operating on it.

It doesn't take a majority of people in anything to create a problem. It only takes a concerted effort by a minority and complacency from the rest.

But besides this, we have too many people fighting a tug-o-war over the term racist. Some people want to apply the word to everyone. Other people think it should only apply to literal Nazis.

But again, that's a distraction. The membership in the Nazi party was around 8.5 million in 1945, yet the population of Germany was around 90 million at the time. That's right, less than 10% of the population were Nazis, yet they controlled everything.

In theory a "user" is more valuable the more you know about them because the extra info lets you better target them for higher response rates. Better privacy means you know less about the user, meaning you are less likely to bid high for that user's eyeballs, meaning the user is worth less ad spend.

The actual story is a little more nuanced: when you target an ad, you are usually bidding for users in an auction. You're generally willing to pay more for more specific filters because you're more confident of a higher response rate.

In ecosystems with a lot of data on every user, specific filters actually work, so you end up with higher bids on fewer users, which should drive the average spend per user up without necessarily driving total spend up. With less data, you have to use less specific filters, so you end up with lower bids on more users, which drives average spend per user down without necessarily driving total spend down.
Apple is not willing to understand the whole dynamic in the ads market, including publishers trying to game with the system all time. I've observed the worst on what those publishers can do and am pretty sure about that they will find out a "creative" way to make up for the revenue loss. Of course, I'm not saying this will be user-friendly; publishers tend to be more "creative" when it tries to rather exploit users.
Growing up, about 10 families all had kids within 18 months of each other, within a 3 mile radius. The parents all got together and worked out a time share agreement where all 10 kids would get dropped off from roughly 9-5 at one parent's house, then a different parent's house the next day, etc so that one house had 10 kids for an entire day, every two weeks. This happened from about age 0-3 pretty religiously. It worked out partly because all the parents were in the same age/ethnic/religious/income group, but it might work across wider groups. It didn't cost anything. We called it the "babysitting group" and 30+ years later I'm still pretty good friends with most of the kids in our group.

I think "modern" parents take their kids to the park to try and socialize with other parents/kids but the unstructured method doesn't seem as effective.
> Do you have any evidence of this?

My only evidence is a very basic evaluation of their publicly stated capabilities.

It sounds like you have a much better informed opinion than I do.

With my limited knowledge, I see no reason why SpaceX wouldn't aggressively go after that market, but like I said, my knowledge is limited.
I see, thanks. I was confusing "logging" for logging the association between AuthCredential and UID rather than logging IP addresses. For what it's worth, Signal does allow connecting over Tor.
I have no idea why you’re being downvoted. That tax rate is incredible and would destroy the earning power of most of hacker news.
> work at home

You mean "work at home" as in, not work? Ever dealt with a toddler? Kiddo will be at your workspace non-stop. You can't just tell them not to either.

If you want to get anything done without distraction, the easiest solution is to park them in front of a TV all day. Not sure if that is the outcome you'd want. Daycare at least gives them a full day of interacting with others their age, learning new things, etc. Not just watching TV or being ignored at home.
We should just give up and do the UBS thing.

The people who actually want to learn would congregate around something that could be used as a decent measure for that and the party people could party and everyone would be happy. We’re near this (if not, we’ve reached it.) if you look at our GDP and what most people are doing for work it makes sense.

I grew up in North Dakota, this bar sounds like a lot of small town bars I grew up around. I'm sure you're right on them being a dime a dozen, our "local" aka 20 minute drive away bar had unpaved roads and also yes did have spots for the horses.
These days they try hard to sell themselves as "the good guys of tech". Tim Cook grand-stands about privacy rights, etc. It's easy to forget that it's all just business, so it's good to be reminded.
Its always surprising when on HN these degrees are considered non desirable and yet every time one of us starts a company we realize we need them.

Improved privacy. The rest of what you said is irrelevant.
That's not 'medalists', it's everyone who gets on the national team. In any sport, even relatively obscure.

Top athletes that receive medals on international competitions get way more, in prizes, premiums, gifts like expensive cars/apartments/etc from federal and regional authorities.

So unless Western amateur athlete has some luxurious ad contract, he/she won't be even close to Russian 'amateurs'.
Eh, from the level of discussion on such issues it seems that every detail of rendering is figured out even outside browser teams. And since afaik it's browser implementors who are defining the spec nowadays, I have some hope that they'll see the light.

I don't think the details are critical to their point though. The fact that it's a brick building with backstory doesn't immediately turn it into a sound business decision.
NIST FIPS 186-5 (Draft) has Ed25519.

https://csrc.nist.gov/publications/detail/fips/186/5/draft

NIST SP 800-186 (Draft) has the curve definitions. But says only for Ed25519, not for X25519. They have a Weierstrass curve W-25519 that is isomorphic to Curve25519 that might allow using X25519 code, but that's way above my ability to judge. 'tptacek or 'jedisct1 or others will know.

Why do you assume the financial institutions, rather than the colleges themselves? Don't you think that a person being paid a salary to teach students skills that are less valuable than what the person pays is also benefiting? What about university administrators?

TLS certificate says different. If malware comes from a TLS signed domain, then the owner of that domain is at-fault. Getting reparations from that domain is of course a different matter. But this should simplify the blame game.

I strongly disagree. Where there's a will, there's a way. And Google has the will.

Absolutely agreed, their CEO search probably started six months ago.

It wouldn't entirely surprise me if The Verge's article used sources that wanted to ensure that the transition happened, and that Korey was pushed out. If you think Korey is bad for the company long-term, you might be willing to take the hit on a single bad holiday to "fix the glitch".

To be clear, I don't think The Verge's reporter was complicit, but it would not surprise me if some members of the board helped ensure the reporter had a single, clear, named target.

I think you could argue it's created a class of wealthy and super wealth admins who don't add value. From what I've read several studies have shown the vast increase in college expense has been sucked up by administrators and non teaching staff. I was looking at my college's (midwest state school) payroll and the various provost were making $600k. Kinda wondering what in god's name these people do.
I wonder if the Cell microarchitecture will make a comeback someday in some form.
Overall cool stuff. It feels like this has implications for auth/authz schemes in general, like a variant of kerberos, or a way to do auth/authz for a ssh like service - maybe even a way to anchor trust (in user principals and service principals - like ssh keys and/or certificates)?

If we replace "the signal server" with "the authentication/authorization service ("the AD service" / the organization's internal certificate authority")...?

Maybe I'm just needlessly afraid of the complexity of managing a real world certificate authority (keeping it secure, keeping it running, keeping as much as possible off line..).
I'd like to see a p2p mesh network where articles stripped of ads are upvoted, annotated, and shared. Something like outline, but truly distributed. The markup doesn't allow for embedded javascript or cookies.

If it were to get popular, a microtransaction system could be built on top to pay the authors. In fact, payment could serve as one kind of ranking heuristic.

Store articles in a blockchain and garbage collect them from your node when they're no longer being actively read. Content will of course always be available as long as some node has the full history. This has the added benefit of making future updates or redaction without explicit change logs impossible.

You could even distribute comments the same way. All participants have keys, everything gets signed, natural interest graphs form...

This type of application of bkockchain tech seems more immediately useful than currency and brings us back into alignment with the old web paradigm. Distributed, experimental, hobbyist, not commercial.

It's gonna be "great" until the first backpack or pipe bomb blows up, shrapnel kills some kids and their parents sue because NYC didn't do like every other terrorism-experienced city and install clear plastic bag receptacles that are basically just an aluminum ring suspended in the air and emptied frequently. An example would be like: London's Victoria Station (when I last visited).

A metal container + rapidly expanding gas = shrapnel. Those decorative concrete and stone trash bins are especially vulnerable to large explosives placed in them..
Take a small drill-driver, put a wooden disk with a peg on it. Mount the drill-driver on the gun in such way that it hits the gun trigger on every rotation.

Voila - cheap semi->auto conversion that works on any semi gun and can be made in under 1 hour and 100 USD.

Or you can just buy a bump stock.

Compared to that hacking the electronic trigger is anything but easy.
As someone currently in China, this comment made me laugh. I don’t think I have ever craved it.

That said, you should try it anyway. I hope you like getting drunk. Personally, the flavor reminds me closer to the chemical alcohol you might find in a science lab more than anything else. It typically starts at 40 proof and goes up from there.
We compared the runtime performance of GraalSqueak with OpenSmalltalkVM (formerly Cog) and RSqueak (RPython-based VM) in Figure 4 of our MPLR’19 paper [1] for the first time. Since then, we've worked on a couple of performance optimizations. So at the moment, I think GraalSqueak is only slower in the DeltaBlue benchmark... in all others, it's (often significantly) better than OpenSmalltalkVM. However, please also note its limitations which we discussed in section 5.2, especially with regard to Smalltalk's interrupt handler and Partial Evaluation performed by the Graal compiler.

So far, I'd say our observations wrt RPython match the ones discussed in "Tracing vs. Partial Evaluation" [2]: Language implementers have to do more work in Truffle, but probably get better peak performance in return (not talking about warmup or memory consumption here).

RE "a more optimized bytecode" set: Sista [3] (an extension of the OpenSmalltalkVM) is doing something like that, too. I'd guess performance would be more or less the same using GraalVM as Truffle produces highly specialized code. But, of course, this would need to be benchmarked. The advantage of the Sista approach is that it's managed on the image level, so specialized versions of methods are persisted as part of the image. AFAIK the GraalVM team is working toward persisting compiled code caches, which is kind of similar but on the level of the language implementation framework.

Hope this answers your questions!

Fingerprinting is much harder in reality than Panopticlick makes you believe.

For example, if you update your browser or add a new plugin, you can look like a new person so it makes it harder to find a match. A cookie would not change through that event.

Enough people have the same fingerprint that it limits its effectiveness. Maybe you can only reliably identify 40% of your user base that way.

It is like using your IP address as an identifier. For some people it can be 100% accurate, but others switch networks or share an IP with multiple other people which limits its usefulness.

What ends up happening is that companies will correlate IP address with other fingerprint information to get a probabilistic match but that is complex and still has flaws.
Sounds to me like the higher order laws of physics are emergent properties of the lower level properties. Is this surprising? Every system in existence is the result of the emergent organisation of lower systems - why would the laws of physics be different?
