In the context of the Trolley Problem, one option is the reality of the present (X amount of lives saved due Gates' success / the foundation), the other option is unknown - it may be Y lives saved. It is possible that this alternate reality might have a better outcome than the present. Can't say with any certainty but it is tempting to guess that X > Y
This might explain why genes for aging exist but doesn't really explain why genes for not aging don't exist. You could have a stable community where e.g. 15% of the population doesn't age and not run into community-level problems because they aren't that large of a percentage of the community, so where are they?

I think many of our problems with the media could be solved by people reading the story and not just the headlines.

Quads are used as geometric data primitives because they allow consistent subdivision. But quads are not good as a rendering primitive compared to triangles. Triangles are rasterizer-friendly because they are composed of two edges and its quick to know if you are inside or outside two edges.

How to Create an Elevator Pitch
It's true that there will be a limit to what dependency tracking can do, because if you rename the nickname of an author of a blog post that is in 1,000,000 pages, then we'll fire 1,000,000 function invocations preemptively to recompute all pages.

That's why Next.js is focused on enabling both eager and lazy pre-rendering behaviors (AOT and JIT). There is no silver bullet :)
Specificity and sensitivity feel really poorly chosen and difficult to remember. You could swap their definitions and the names of the terms would make just as much sense. I much prefer true positive rate and true negative rate.

It’s not a replacement for react. It’s built on top of react and gives you all the best practices for SSR and development setup out of the box. It’s been highly optimized (including with help from the Chrome team), and is in use at some very large websites.

I can’t recommend it enough. Although if you’re doing anything with moderate complexity, it is still important to understand what’s going on under the hood. At least, you should know the difference between client side routing and server side routing, and any implications of when you might need to treat one differently than the other. I could see a total noob potentially getting hung up on that aspect of it. But the rest of the ease-of-use outweighs any complexity stemming from SSR, IMO.
This is pretty neat! I was just looking around for a "modern, smaller" JQuery equivalent and did not come across this. The older equivalents in this space I saw were Zepto and Cash.

Out of curiosity, what do you think of Alpine.js and Stimulus.js, which come to mind when I think of smaller utility libraries for adding "sprinkles" of JS?
Survey of Prescient Actions
I’m not sure on Pulumi specifically, but a .catch on a non-awaited promise should be fine.
In a similar vein, I worked (eg: interned) at a few recording studios in my 20s. Most tracking in both was done to a 2" 24tk analog tape deck and the majority of post and mixing was all done digitally. I don't know what progress has been made in plug-ins in 20 years, I suspect a lot, but at that point there was nothing digitally that came close to the sound of electric guitars overdriven into the tape deck and saturating the tape to an extreme. Now I'm curious if anybody has gotten it right, but there are fewer and fewer studios with 2" tape decks to do a true A/B.

Yes, regularly, because that's what effective teams do. I also limit bandwidth to 3G and record the sessions so that everyone can share in the learnings, which very rarely circle back to things like TTFB/TTI.
Been testing it out the beta, in my experience performance is better but still behind tslint, though tslint lacks a ton of rules compared to eslint so I am guessing that is partially why. I think the webstorm struggle is a webstorm specific issue, I've seen a few of my co-workers experience similar webstorm slow downs from eslint (and ts) but it works fine for me in vim without any slowdown of the editor itself.

That can't be discounted, but if you have two tests that target different epitopes of the virus (hence, independent), the probability of them being wrong at the same time is

(probability of independent events), hence much lower.

I definitely agree he had a mathematician working with him to help, but am not sure it was his wife. I think that there's varying interpretations of her contributions to A. Einstein's work. If I'm remembering correctly, Walter Isaacson's Einstein biography tended towards says that she didn't truly contribute much to any of the work he did around that time, but that he did have a colleague or two formally trained in non-Euclidean geometries that he spent a lot of time working on GR with.

I've got a Surface Go 1 and it's kind of just "ok". It's not a great tablet or laptop. It's useful in that it can run Windows-only stuff in a portable form factor but I tend to avoid using it for daily tasks.

I've gone through several Surface tablets going back to the Pro 1. I'd hoped they would be nice portable Windows machines for tasks I need Windows for but small enough they would be easy to tote around or put away on a shelf.

Due to their size they are (for me) shitty tablets. The Pro 1 and 3 were just too bulky to use for more than a few minutes as a tablet and the keyboard covers are just finger trampolines and make terrible laptops. So they were just crappy desktops I could fold up. The Surface 3 was a little better as a tablet but a shitty laptop. Finally the Surface Go was a decent tablet, still a shitty laptop and foldable desktop but more capable as a tablet.

The Go is my last Surface though. It turned out to be my best deal since I got it on some clear-the-channel sale so got the 8GB model for like $250.

Last fall I bit the bullet and just got a cheap gaming laptop on a Black Friday sale. I was able to stuff in 32GB of RAM and a 1TB SSD. It's at least a good laptop and a decent desktop and I can still put it on a shelf. It beats all the Surfaces I've owned for Windows-only tasks.

The Surfaces look nice and have some of the best Windows pen interfaces you'll find but they are just too compromised. Their attempt to be tablets makes them shitty laptops and then they're pretty poor tablets.

Nextjs is an opinionated stack that specializes in SSR, routing, and bundling.

React/Redux are building blocks to your own "React Stack".

You can use other state libraries (like xState, MobX, etc) depending on your programming style (reactive, state machines, etc.)

It depends what you want to build. You choose how you stack it.
Anecdotal, but it's an incredibly satisfying development loop for anyone with a limited staff. Deploying to Vercel gets you so many convenient tools out of the box, and I haven't even left the free plan. Very helpful in a startup environment.

It would be an interesting experiment to visibly prepend the search queries each employee had done before asking a question to their actual question, in order to discourage asking questions before searching for the answer. You said you had built your own search solution, so clearly you could wire up a form that actually does this.
I've been working on something similar for the past couple of days, but the trouble comes with wanting static types. There are a few projects out there that offer either a microdata parser, or types derived from schema.org but nothing that combines the two as yet
you're right, it's hard to find that definitively online. however, it lists it on my emailed test results as well as a friend's who did it on the same day. that doesn't mean they're not using multiple test types though. maybe worth calling and asking if they use it everywhere?

Sounds more like vampire-fiction like historical realities. People were "burned at the stake" for heretical ideas and challenging church dogma, not for looking suspiciously young. And the examples we have of living persons being deified was generally because they acquired enormous power (roman emperors, pharaohs and so on) not because of looking particularly young for their age.
You’ll probably need to be more specific about the speed issues you’re seeing. I don’t see that issue, but I also factor my code into smaller packages in my monorepo (which is a good practice). I still have relatively long lint times against the monorepo (greater than a minute), but that’s part of the CI stage.
Honest feedback, this didn't really explain electricity for me. What is does is introduce an entirely new analogy for understanding electricity. Unfortunately, most elements of the new analogy are not relatable at all, meaning the analogy has no value. What do I care that the electrons "rotation" means charge and the speed means voltage? Why are they shaped like breathmints, how does that help if they are supposed to be gears?

At least the water and beads analogies help, because they are something I have a previous understanding of.

For what it's worth, I enjoyed the music and the typeface. Made me hang onto watching the video much longer than I would have otherwise. The VO is also good.
Yes, scope and liveness are not exactly the same. No, that does not mean the scoped value cannot be restored cheaply. DWARF can express the value of a variable in terms of expressions that do computations on other registers and/or access memory; it does not have to be as simplistic as "this value lives in this register for some period of time." Clang (and to a lesser extent, GCC) fail to do that for non-live, in-scope registers much of the time. Clang in particular just loses that metadata in many optimization passes.

Please explain these efficiency benefits. VDOM architecture can't be faster than native javascript updating the DOM because at the end of the day you still have to to use native javascript to update the DOM.

The answer to your question is "Because it makes business sense to do so". Whether you can understand their reasons or not, the best indicator that Netflix has good reasons to use AWS is that it continues to do so. And that will be true until the (possible) day that it doesn't anymore.

> I think the answer is Yes.

So what you're saying is that (1) Netflix is already secretly planning to move away from AWS, in which case your question is moot, or (2) everyone involved in platform decisions at Netflix is an idiot that can't do math.

The idea is that transfer of momentum between atoms is a good approximation of current. In that sense, the difference in shell momentum, on average, can be thought of as potential or voltage.

Like the hydraulic analogy, this visualization is to help us understand not an exact movie of what's happening. Math may be better for that level of detail, for now. This visualization uses atoms, which is the main advantage over the hydraulic.

If you think there's a significant chance the market is wrong in its assessment of risk, you can make a significant amount of money by betting against it. For example, as of the time of this writing, put options at $310 for December 31 on the S&P 500 (current price $293.94) cost $33.09. That means that if there is at least a 50% chance of a 17%[1] drop in value of the S&P 500 at any time between now and December 31, you can make money on average by buying those puts and selling them as soon as prices are down by 17%. The possibility of making this bet means that the market as a whole is 50% confident that stock prices of the S&P 500 will not drop by at least 17% before December 31.

Likewise, option prices imply:

- A 75% chance[2] prices won't drop by 26%+ (which would be back around the low from late March 2020) by the end of the year

- A 90% chance[3] prices won't drop by 48% or more (around the movement from when it became clear that something was deeply wrong in 2008 to the bottom)

- A 95% chance[4] the price won't drop by 58% or more (which is around the peak-to-trough movement from the 2008 financial crisis)

- A 99.5% chance[5] that the price won't drop by 90% or more (like the great depression).

While it's _possible_ that the market is wrong about its assessment of risk, that would also mean that it's wrong about its assessment of its assessment of risk, and people who are better at risk assessment could clean up.

-----

[1] Ok, technically a 50% chance of a drop of 17.05%. ($310 - ($293.5 * 0.8295)) / $41.75 == 1.9999 i.e. if you buy now and sell as soon as the price drops by $17.05, you make a 2x return on investment.

[2] $20.77 for $280 puts expiring Dec 31

[3] $4.62 for $200 puts expiring Dec 31

[4] $1.83 for $160 puts expiring Jan 15. I actually have a small position here, because "95% chance this isn't at least as bad as the 2008 financial crisis" seems a bit overly optimistic to me.

[5] $0.16 for $75 puts expiring Jan 15. Note that there is extremely low volume this far out on the tail.
How to build side projects while employed full-time
Show HN: Easy to understand, visual explanations of the latest Covid-19 research
Hey HN,

My name's Neil, and I'm helping a group of scientists and physicians publish visual summaries of the latest COVID-19 research at https://www.researchexplained.org

Our goal is to stop the spread of misinformation by making it easy for people to understand the latest scientific research without being a subject matter expert.

It's difficult to determine whether a news headline is really supported by the source paper. The study could have faulty methodology or the news source could misrepresent the conclusions drawn by the researchers. While the scientific community relies on peer reviews to promote high quality papers, the general public is not qualified to review every paper, both due to lack of context and time. Instead, they rely on summaries from mainstream media sources, who tend to report on papers before they have passed the necessary peer review process. This creates a gap between when a paper is posted and when it is vetted and accepted by the community.

While this has always been an issue, the problem is more dangerous right now. With the ongoing pandemic, preprint studies are getting a lot of media attention without proper explanation of the caveats that come with that (no peer review, preliminary data, etc).

To combat this, we are creating objective summaries of the quantitative facts presented in a paper, along with a rating of the media's coverage to highlight any issues.
There's been a fair bit of discussion around COVID-19 studies on HN lately, so I'm curious to hear what you all think of this approach! We just started, so only have 3 explanations published so far, but will be publishing 1-2 per week. This is a purely volunteer-driven effort that we're doing on the side to try to help how we can.

The idea was partially inspired by Distill (https://distill.pub), which is an excellent ML publication.
Look at pluralsight, everyone should be able to run video on 2x speed. One hour explanation I can watch in 30 minutes. If it would be written I could skim even faster and read interesting parts... But people don't read that is the problem.
