Doesn't extended upside-down flight require pointing the nose up (as in away from the ground) in order to compensate for the decrease in lift? I've yet to try this (I suppose I could; I've got an X-Plane-running flight sim rig about 10 feet away from me), but my intuition and understanding suggests that if the only difference between two planes flying in the same exact atmospheric conditions is that one of them is upside-down, the upside-down one will start losing altitude.

It's because anyone who has done any complex web app development knows that you don't have one button changing color. You have 100+ UI components whose state may depend on one another, and as the DOM nodes composing those UI elements get state attached to them, it's EXTREMELY easy for them to both (1) get out of sync, and (2) thrash and re-render entire trees of the DOM unnecessarily. This is a real thing that happens frequently and is why people think JavaScript causes pages to be slow and janky.

React lets developers pretend they CAN just re-render entire DOM trees from scratch without those consequences, as if they were serving up a fresh server-side render of the page.

Also, suggesting that before React, web apps were updating all their DOM nodes in O(1) time is insane – even if it's not the absolute fastest, why does it compare so favorably in actual tests, then?
That's such a weird way to look at it. They offer DDOS protection to anyone and everyone, and they don't offer anything that could be used to perform or relay DDOS.
After the wing passes, the air is no longer compressed, and the net motion of the air is unchanged from before it encountered the wing. What then?

Anyway, I'm not saying you're wrong, I'm just saying that thinking about the individual forces involved leads to more complexity than necessary (this is usually the case). It's much simpler to just consider the energy going into the system and derive the net work produced from that.

They offer EV certs, so there's some cost involved in doing the identity verification. I don't think it's $234 dollars a year, forever, but it costs something. And that's actually a pretty competitive price for an EV certificate.

In practice, until they change the law so that the service providers can determine fair use and discard the DMCA request in fair use cases, nothing will change much. Litigious people and organizations will file and file, and the service providers will have to take it down. If the service provider doesn't follow the process, they lose their safe harbor. And there's virtually no room for the service provider to exercise discretion-- they need to act on the DMCA's they receive, as long as all the required components are present.

Ask HN: Anyone in NYC area want to hack?
Hi there! I'm tired of being a cog in the machine. I'm going to attempt the impossible here on HN: find a co-founder.

If you are in the NYC area and aren't entirely repelled by the idea of starting a startup, are an exceptional programmer, and want to get together with other exceptional programmers and build stuff for fun to see what happens, read on.

It's not all about tech in a tech company of course. People, sales, and determination matter. One key seems to be working well together as a team, committed in a shared partnership. Another is trust between co-founders who will be practically be married to each other. And playfulness, and audacity to try crazy ideas out to see if they'd work, which is practically what hackers do anyway.

Don't like being told what to do? Here's a chance to start something your own and run the world by your rules.

Post here or shoot me an email. It'd be nice if you mentioned a hack you are playing with and other awesome stuff you've done.

With client tooling like GraphiQL and editor plugins, it should just get better.

We lose more than that directly via coal mine accidents every year. Add in the deaths from pollution and the math gets even better in nuclear's favor.

I have yet to see waste from solar or wind mismanaged, or a solar or wind plant not be cooled properly after a fault, causing a meltdown.

Everyone comes to Hacker News comment threads like this to expound that nuclear is the way, while solar and wind continue their march towards domination. A nuclear plant takes ~10 years and at least $1 billion USD to come online. Solar and wind are going to be even further along by then.

Then we are due for an ArkStorm or Atmospheric River.

From the USGS:

"...This document summarizes the next major public project for MHDP, a winter storm scenario called ARkStorm (for Atmospheric River 1,000). Experts have designed a large, scientifically realistic meteorological event followed by an examination of the secondary hazards (for example, landslides and flooding), physical damages to the built environment, and social and economic consequences. The hypothetical storm depicted here would strike the U.S. West Coast and be similar to the intense California winter storms of 1861 and 1862 that left the central valley of California impassible. The storm is estimated to produce precipitation that in many places exceeds levels only experienced on average once every 500 to 1,000 years."

The majority of people who fly do so in cattle class, where basically the headline ticket price is the biggest factor in choosing prices (which is why low-cost airlines offer cheap tickets but charge steep prices for doing things like bringing luggage or getting a drink on board the plane).

You can't fit enough people in first or business class to fill a plane on most routes, and you simply can't go fast enough to make speed premiums really worth it. Note that going to an airport usually requires on the order of 2 hours of hassle before accounting for flight time, which means that you've already lost a day of work in practice. No, unless it's a long-haul flight, there's little benefit to faster speeds, and the Concorde was never really profitable.
A Primer on Disassembling Function Calls and Understanding Stack Frames in X86
TLDR

The Fermi Paradox (a.k.a. "Why hasn't some alien civilisation already visited us?") contains a hidden assumption that a space-faring civilisation will expand rapidly to fill the galaxy. But such expansionist civilisations are likely to collapse when they reach their limits and exhaust their resources.

So we should be looking for either small civilisations that have managed their growth, or the "graveyards" of civilisations that didn't manage their growth, reached their limits, and collapsed.

And the implications for humanity, with its own expansion and resource problems, are clear.
I've been pro-nuclear for a long time, though the Fukushima disaster changed my mind a little.

What shocked me more than anything about the accident, is that when things go horribly wrong with Nuclear, we literally have no plan. We have no way of getting inside to stop things getting worse, or to contain what has already happened. We literally stood around watching, waiting, to see what would happen. When the highly contaminated water flowed into the ocean, the response was "where else did you think it would go?".

I'm aware that new reactor designs mean things going that badly is very unlikely in the future, but I still think it's scary we can build a machine with such immense power, and it can get to a point where we just stand back and watch it go bad.

If we ignore the challenges of creating and operating an earthquake and human error proof station, waste is still not a solved problem.

The fact that the famous Pentium division bug is still being talked about speaks highly of processors as bug-free software.
It was a fascinating read of evolving a system from 8-bit to 32-bit to 64-bit with many rational or clever development choices. I like how they kept improving performance while keeping quality as high as can be. The willingness to rewrite or toss what was necessary to keep the whole thing sensible is quite a contrast to other legacy systems that force people to work around crud forever. They also learn from the past better than most in that a solution to an 8-bit problem in version 1 ended up solving a similar problem in the last, 64-bit version. Shows value of keeping those old tricks and papers stashed somewhere just in case.

Definitely adding it to my collection as there might be lessons for a Racket reimplementation or a certified LISP project in the future. Hell, their low-level stuff might even be useful in a LISP processor or hardware/software architecture. Who knows. Thanks for the good read, though.

This article, like many pro-nuclear arguments, doesn't address the most basic problem -- is nuclear power cost effective?

Sure, it's cheap in theory, but nuclear power projects bring with them enormous project management risk. If you complete 90% of a wind farm installation, you get 90% of the power out. Completing 90% of a nuclear reactor gets you no power at all, and unexpected cost overruns can add up to billions of dollars. When a reactor shuts down for repairs, they sometimes take decades to complete. As of today, it can be argued that many countries' nuclear power programs were a financial mistake.

Then, once in a while, you find out that the original cost-benefit analysis was wrong. After the Fukushima accident left $200 billion of real estate uninhabitable, nuclear power plants across the world have revised their risk models, and now are spending more money for safety upgrades.

Finally, emerging technologies like wind and solar are showing immense promise, but predicting their future cost is equally difficult. All the best minds can only put together a very educated guess.

Yes, if we had started focusing on nuclear power 40 years ago -- and if we had done it carefully and properly the first time -- it would have been the right decision.

But we got it wrong, and the today risks of getting it wrong again are bigger than ever.
