(Author here) Thanks - and I agree. That being said this is running 100 MHz on (what I believe is) a relatively low end FPGA? Also my implementation remains simplistic, many things to optimize. But this is a very good and deep question: how can we compare these things? What is the right metric? (FLOPS per watt? err, no, no floating point involved ;) ). I am wondering and this seems quite a difficult/subtle question.

I love GPUs, I spent many year working with them (still do!) and these are beautiful pieces of hardware and engineering (as modern CPUs are). They have evolved beyond our craziest dreams since the NVidia register combiners (https://www.khronos.org/registry/OpenGL/extensions/NV/NV_reg...). The performance we get nowadays is absolutely mind-boggling (I often think we don't fully realize how powerful they actually are).

Can we dream of some sort of mixed platform, where we could 'burn-in' very specific functions into FPGA type hardware that would seamlessly interact with our modern GPUs/CPUs? Is it already happening?
I think people should be free to create as they like. I don't think simply because something resembles an article, it must be an article. Personally, I would like to see pages that blur the lines between articles and virtual interactive museum exhibits, but I certainly don't think that my preferences should be the default. As long as there are the necessary accessibility provisions (which also provide for you to be able to read any page as a regular article), what gives? If you want a text based internet, use a text based browser.
There is so much we donot know about the long-term effects. It shocks me to Silicon Valley icons like Elon Musk, Paul Graham, and Justin Kan pushing to reopen and spreading conspiracy theories over building tools to understand the long term effects.

Price gouging means you took stock on hand and re-priced it to gouge the desperate with no increase in cost to the seller. It also covers people who buy out the retail stock in 4 states to "corner" the supply, and then try to extort high prices for necessary goods due to an emergency.

A price increase due to shortage is legitimate if it is new stock or production, brought online or made possible by a higher price that is now sought to satisfy demand.

China is a big place. Imagine any possible negative health complications, we can safely assume that at least one person in China has developed it. The question is, what fraction of people have developed these complications? We don't even know what fraction of people developed the disease, or what fraction outright died...

> I apologize for constructing a questionable example

No need; as an example of segmentation, the one you've presented is fine. The biggest problem, mostly irrelevant, is that "prince's courtyard" is pretty archaic. I was objecting to the translation-in-passing of 王家 as "prince". It's defensible to segment the "prince's courtyard" sense 1-1-1, but it's also defensible to segment it 2-1.

I don't have an example of the type of you're looking for to hand, but I will see about finding one.

> Women are not "discriminated against" when it comes to signing up for computer science classes in high school or choosing to major in computer science in university, yet significantly less of them sign up for these classes then men. There is no discrimination going on here since any women can sign up for any class of their choosing in high school. Clearly something is causing this gender imbalance, what might that be?

Gee, that must be some sort of biological factor! Certainly not related to social aspects outside of signing up for a high school computer science class.

Things in air travel did not go back to normal though.

Cockpit doors were reinforced, with nobody allowed in during flights.

Things on the ground were even more changed, with security still heightened to this day (even if much of it is theatre). AFAIK, it was also around then that tickets became non-transferable. People's luggage can no longer travel with out them. We have 3D body scanners and can only carry small quantities of liquids in a tiny bag (I realise this came a bit later, but the point stands). Being brown results in even more unpleasantness.

Things absolutely did not return to normal after 9/11.
I've heard "new normal" in common usage for [at least] most of my adult life (I'm 37). I don't think I've ever been confused about its meaning either. "New normal" implies some prior normal, and represents a substantial and permanent delta between the two.
You can usually card count and run all of the old tricks when new jurisdictions just get into the casino business.

Like a new tribe finally gains consensus to open a casino and have no idea what they're getting into or have the enforcement procedures. The same for states and municipalities, but they typically have more resources to course correct quickly.

You can take them all to the cleaners though.
Almonds and avocados are vegan. So is bread. Made from wheat. So pointing out that some crops are bad for the environment is a straw man. I'm not a vegan by the way, I just find it completely absurd to suggest that a meal consisting of vegetables kills more animals than a meal of meat, when animals raised for slaughter require huge amounts of land to be dedicated to growing feed crops.

I think more comments than points is a negative rank factor on HN. Probably because it unmasks the submission as argument fuel for HNers.
You're right, but it's getting downvoted because it has the same basic shape as the "people aren't creating antibodies and can get reinfected" doomer meme which is making the rounds.

Also, FWIW, if getting the actual disease doesn't generate sufficient antibodies to confer immunity, being dosed with a vaccine wouldn't either. Whether vaccine-supported or not, herd immunity is the most likely outcome (unless the disease becomes endemic instead). What remains to be seen is how many people have to get ill to get there.
Git works nicely on Linux for Chromium with over 540K files spread across a few modules. On Mac and Windows it is kind of tolerable, but with git status taking 5 or more seconds, I started to use “git status directory” to get more instant feedback. And git blame can take more than a minute, so it is often better to look at the log and guess the changes from it.
You just earned my respect.

>I'm so utterly and completely burned out by being "a patronising and evil" presence when I make the mistake of trying to actually confer real information to people.

Step down from your high horse. You're just parroting PR talking points that are totally nonsensical. If game studios could save money by offering dedicated servers they would do it. They switched to official servers not because they care about the experience but because it allowed them to monetize online play better. You can't sell hats when players can host their own servers and mod it however they wish. Why would I buy a hat from Infinity Ward when I can just mod myself a hat on my dedicated server?

>If it's dedicated servers that you rent from us as a company then: it can be expensive for you, if it's too expensive, less people do it, less people do it, the more expensive it becomes to maintain the provisioning/admin tools and it's amortised across much less players so the price goes _even higher_.

Again, if it were possible for game studios to make more money by offering dedicated servers, they would do it. You are inventing problems with dedicated servers so that you can ride in and be the hero when you solve them. These aren't actual, real, problems. These are just PR talking points to justify forcing official servers so that game studio have better monetization paths.

>As I've stated repeatedly in this thread: Self-hosting servers only works for session based games.

No, it doesn't. That is a limitation you (game studios) have invented. There are dedicated servers for World of Warcraft.

>But you don't want what you think you want and I'm not trying to patronise you by saying that.

Ah yes the ole "I know best." The final landing spot of ridiculous arguments.

Hello HN,

I want to respect users time when collecting the testimonials and ask for only the most useful aspect. Herewith, like to consider HN community opinions on whether you as a Saas user concerned about clientele and testimonials? If yes, what is the one vital thing you look in testimonials, to buy the subscription?

Your views and experiences will be a great help.

I'll just mention a side story for people's interest. You may notice that Ellis Island is connected to New Jersey by a small bridge, in the maps and satellite view.

That bridge is a service bridge, but it isn't implausible that it could be adapted for use by pedestrians to visit Ellis Island. It might involve a few $m and an environmental review, but it has been considered before.

However, despite periodic questioning and advocacy for it to be allowed for pedestrians (to decrease the cost of people visiting, and make the island more accessible), the NPS has stated that "an approach by boat is important to the experience". A $19.25 ticket, run by a private ferry company.

Go figure.

What kind of evidence are you looking for? I can point you to public health authorities saying immunity works and lasts for ~a year [1][2], but I suspect you've seen these statements already. If you're looking for a scientific study unambiguously proving it, we of course won't be able to have that until a year has passed.

You're right, the question of where the break even point is is quite complex. Aside from the numbers you posted, it also depends on the economic side effects of "intervention A": better to be one of the 40,000 with long-term illnesses in a functional society, than to avoid the long-term illnesses but live in a non-functional society because we destroyed the whole economy.
The Georgia Tech Graduate Who Never Existed
I think that, in the terminology of the paper, a higher proportion of New Yorkers would be considered 'high-active' compared to, say, LA, and perhaps there is a level that you don't even see in less crowded-mobile societies. I would guess it is helpful to keep the biological and social factors separate when modeling what is going on.
Probably. Dell/HP/Panasonic have equivelants that are nearly as good, but named differently. I don't know if those involve royalties to IBM or Lenovo. TEX Keyboards in Taiwan also makes a TrackPoint-enabled keyboard too.
You are right. Hostility and sarcasm are not the way to convince people. I think in the most generous reading, the commenter is trying to cushion the criticism by taking a teasing tone, but may have missed the mark a bit.
IANAL (or economist), but I'd say price gouging is when hoarders raise prices to profit from artificial shortages that they created.

As a people, we did not run low on hand sanitizer. As a free market, we ran low on hand sanitizer because a small minority decided they needed 10,000 bottles in their garage.

When there exists plenty of product for everyone, and there are distribution networks by which we can get it to everyone who needs it, and yet opportunists insert themselves in the middle for no purpose other than to make a quick buck, I call that price gouging.
Caddy 2 vs. Nginx Benchmarks
As I understand the Swedes, Herd immunity is not the goal they are working towards, but a possible bi-product of their strategy. The strategy as such is to keep the curve low enough, pretty much the same as everywhere else. They've just used less extreme measures to achieve this because they don't think it will matter in the long run.

> It shocks me to Silicon Valley icons like Elon Musk, Paul Graham, and Justin Kan pushing to reopen...

In fairness, they might be pushing to reopen to make the governments do better than rely on lockdown indefinitely. After all, necessity necessitates invention. One way to reopen and still be on top of the epidemic is accurate, fast, and cheap testing [0] at scale, so that, not only could people be tested repeatedly to curb the spread but also get a good overall data on the spread itself. Contact tracing, social distancing, and quarantine remains essential till a vaccine, or a prophylactic / therapeutic treatment is discovered.

I'm also a bit suspicious (apolitically) about the current administration's 'attention' to the stock market. It's uncommon to see presidents tweeting all-time highs every week and it wouldn't surprise me if in a few years from now we found out some shady propping up had been going on.
Likely it's real, but we'll see. Still, that is ... well ... a bit unusual.

My grandfather gave me a puzzle when I was 8 or 9 years old where the goal was to trace a path through each of the "walls" in the diagram below without the path crossing itself:

---------------------
| | |
---------------------
| | | |
---------------------

I played with it off and on for years and suspected that it was impossible. I realized that it is in fact impossible when I took discrete mathematics in college and we covered the Seven Bridges.

I've passed this on to my kids but only let them play with it for hours until revealing that it's not possible and getting into the theory of it.

I don't think my grandfather knows this is impossible, and I haven't yet remembered to tell him.
>Low-orbit satellites spend half their day in darkness too. To hit a receiver on the night side of earth a satellite would have to be at a very high orbit, reducing beam efficiency and increasing launch costs.

Pedantic, but for LEO there are dawn-dusk SSO orbits that ride the terminator [1] so they get continuous sunlight, you could power some peoples evenings depending on how far the grid spans into the dark side. Not a solution for getting power at 2am though.

Might be able to compete if the cost if a rectenna is cheaper/kwh than solar panels (and free as sunlight). Then you can use your same battery solution for night time.

> the use of the term "proton" in chemistry which they use to denote the (positive) hydrogen ion

H+/K+ ATPase is a proton pump, not a hydrogen ion pump. It evolved to pump protons, and mostly pumps protons.

> the term "proton" belongs in physics exclusively and not chemistry which only deals with point-like nuclei carrying mass plus an electric charge, and the electron cloud

Lots of biological machinery fails with heavy hydrogen isotopes, including some proton pumps [1]. This is why heavy water is poisonous [2].

With the death rate is so slow for large portions of the population, the vaccine will have basically no margin for error. How do you convince parents to vaccinate kids for a disease that has say a .001% fatality rate for those under 17 unless the vaccine is even safer?
I think suburbanization has had a much larger impact than partisan media. Most Americans consume centrist media[1], but there are very few places now where there isn't a large majority of either left or right[2]. With the current political atmosphere, even if 15% of the population is the opposite of the majority, they probably aren't going to feel very comfortable being vocal about it.

You're probably on to something with religion. I'm Roman Catholic, and I remember a lot of Democrats being around at the church where I grew up, and obviously the Catholic church is a fairly conservative organization, and both of my parents are staunch Republicans (The 2 times they didn't vote republican in a national election were when my dad voted for Perot in '92 and my mom voted for Clinton in '16 (but straight republican down-ballot in both cases)).
