Two of my cousins, twin brothers coincidentally, are both astronomers. One is in research and the other teaches full time now.

You’re right, that of almost any PhD I know (admittedly not that many) they are both able to explain what they have studied or written about clearer than any of the others I know.

The family loves when they both get talking about this theory and that, it makes for great conversation the rare times everyone is together.
It's not that clear. What the FAA bans does influence the TSA list of what they check for. Also, I did specifically mention airlines.

Or do you really think this list (https://www.tsa.gov/travel/security-screening/whatcanibring/...) wasn't influenced by the FAA? Note quotes like "For more information, see FAA regulation: 49 CFR 175.10(a)(4)."
No, it's simply a collectively difficult thing to accomplish on our current path.

Your take is simply a disempowering reason to stay stuck. We can always reconnect with nature in various ways. Your perspective is self-limiting and keeps you from realizing ways to accomplish it.

Other people are probably figuring out how to do it and you haven't even bothered to find out how.

Here's the first link I found from googling "how to reconnect with nature while living in a city." These are decent approaches and I would say are barely scratching the surface.

One of the problems with async is that it's viral. Make a function async and your entire call graph has to be made async, unless they handle the future manually without await. Async introduces a new "colour" to the language.

Not in Rust. Or C#. Or any language except JavaScript.

In Rust, a synchronous function can call and block on an async function with executor::block_on(). C# has Task.Wait() and Task.Result(). Python 3 has asyncio.run(). Scala has Await.ready() and Await.result(). Kotlin has runBlocking {}.
I certainly hope not--personally my wife and I had an exchange student from Turkmenistan stay with us for a year and she lives in the capital and could easily be harmed by any sort of violent collapse. But even setting aside my personal feelings, a collapse in Turkmenistan could cause further chaos in an already chaotic region as hordes of poorly trained refuges poor into surrounding countries that are already struggling with their own populace.
I feel like it was just last year when some deep fakes were coming out and people waved them off as having obvious artifacts and too easy to ignore

Any search engine is going to want to know what people click on so they can make their product better. For example, I just searched for [test] on DuckDuckGo and when clicking on the first result I see DDG sending a ping back:

which contains which URL I clicked.

Yet at least half of all comments on HN are ideological and political from how they read and what arguments they invoke. There is no incentive unless you are playing a game to respond to a political or ideological view from a purely curious place and half of the views posted on HN are ideological and/or political.

There are plenty of dams, such as run-of-river dams and specific locations with no fauna, where they do not have a significant negative environmental impact, and may create new habitat where previously there was none.

You’re referencing an undergraduate memo. I’m sure you could find something more authoritative if you want to try and convince people nuclear waste is an insoluble problem.

Nuclear waste is a political problem not a technical one. It’s either still hot and could be used for fuel or not and relatively safe. The hot stuff can be burned in reactors; we don’t because that requires plutonium cycle with the obvious weapons uses. Cold waste can be allowed to decay for a few decades, vitrified by mixing with molten glass so it’s chemically inert and stored in a geologically inactive area, anywhere far from continental plate boundaries deep in the ground[1]. It could also be dumped in deep marine trenches at subduction boundaries where it would eventually be returned to the earth’s core. If you want to get it off Earth altogether I’m sure we could get it to the moon if we really wanted.

You don't need a barrel shifter. You can shift one bit at a time. It's slower, but takes far fewer components.

Capacitor memory addressed with tubes seems a strange choice. DRAM is capacitor memory, of course. Atanasoff, who had a a sort of computer in 1939, had capacitor memory, but he had to use a drum rotary switch to address it.

Memory was the big problem in the early days. IBM had an electronic multiplier before WWII, and plugboard-programmed machines, but no good memory elements. (Just registers with motor driven wheels and clutches and contacts.) Pilot ACE had a delay line (slow, serial access), the Manchester Baby had a Williams tube (too expensive per bit, but random access), and the EDVAC had mercury tank delay lines (slow, serial access, and toxic). Whirlwind (1951) had the first core memory (expensive per bit, but got cheaper over time.)

Core would be a reasonable choice for a tube system. Addressing is XY, so you need O(sqrt(N)) tubes.

Memory was a million dollars a megabyte as late as 1970.

> I suspect the rationale is that any potential for exposing new parts of the battery chemistry to water are dwarfed by the effectiveness of stopping the thermal runaway, and battery chemistry that's already reacted can't react again.

Immediately following that clip is an exhibit showcasing the deployment of a Halon extinguisher to extinguish the fire followed by water to cool the battery pack.
Those are some pretty massive generalizations that fall apart immediately compared with my experiences.
haha that's great. You really have a good dentist.
I wrote code for a MCU that did power sequencing on a consumer product. 4K of code, 2K of RAM, some EEPROM, a 16Mhz clock . . . 18 cents.

Interesting! I wonder if that's a big problem for them.

I tend to lose fancy water bottles, so I buy what are nominally single-use bottles and just refill them. I'm sure I get 10-20 uses out of them on average. But I figured my behavior is rare enough that it doesn't matter to the people selling the water.
You're doing it wrong.

My top repo has ~5,000 stars and some contributors. It was fun, it lets you broadcast AM on a stock MacBook or iPhone. That's how I found Hacker News, it found me. Zero dollars. Virtual tip jar, zero tips. I got everything I wanted out of that project and more.

Next, I open sourced my research on vowel pronunciation / language learning. The same exact program sells on the App Store. For $10. Yes really. And the app links to the free repo, in case they want to check it out. This pays rent.

Next, I'm an expert on some blockchain topics. And specifically related to enterprise. If you're in that scene you might recognize me, I'm all over that (=all over GitHub). I put my phone number in a few choice places and qualified people call. This lands large contracts, no interview. This pays rent.

Google and Facebook regularly interview/hire directly from GitHub. No resume, direct interview request from GitHub. I don't work for Google any more, but these are opportunities to pay rent.
Unless the glass is directly recycled (collected, washed and refilled with the same product) they are much more energy intensive than plastic or aluminium to produce.
Its far from a pleasant place. My wife and I had an exchange student from there and while she was a firm believer in the system (you don't get to leave the country without some serious trust from the authorities) but even she could tell you that buying things from the government shops was fraught with fraud, poor quality goods, and lines. Everyone shops at the non-government bazaars and you can buy smuggled goods there for inflated prices--but the goods are of a much higher quality than what you find in the government stores. You can also buy US dollars in the bazaar, which is what everyone does because the local currency (the manat) is essentially worthless and the value fluctuates wildly.

A 'fun' story about our exchange student and goods--she would save her pocket money (allowance, some small money she would make by doing errands for people) all month so she could buy a kg of Turkish salt. See the Turkmen salt you could buy in the store is made from the Caspian sea (distilling salt from the water) and their filtration is crap. So the salt you buy is brownish in the bag, and is filled with small rocks and other clumps of junk. So when you buy a bag of Turkmen salt, you have to carefully clean it before use. Otherwise you bite into your rice pilaf and break a tooth on a stone--which is what happened to her mom. Thats what finally pushed her to take the small amount of money she had and spend it on buying salt for her little family.
Knowing it exists at all is the long tent in the poll. If I need some way to get my next item based on some form of priority, knowing about heaps and priority queues helps me not build something kinda similar that is objectively worse.

Not much of a coincidence - that happens to be right at the limit of how much power capacity you can have and still being the device on a plane per FAA regulations.
What’s also note-worthy is how often MacBook Pro batteries get a bulge. I had 3 in the past few years and every single one of them got a bulge. I really hope Apple would somehow fix this:(
Uber Makes Its Drivers Pay
It seems like the author wasn’t targeting benchmarks exclusively, and comparing the price of a CPU to the price of a whole system isn’t fair. I spent about $2200 on a system that was targeting compute value- I have 4x E7-4890v2 for a total of 60 cores and can get >80000 on multicore geekbench. I also have 512GB of RAM, which I think is more than Ryzen can handle.

I paid $85 per CPU, so while a new Ryzen 9 does make sense for a lot of people with its fast single threaded speed and low power consumption, the old server gear I bought still wins in highly parallel tasks for less money.

Edit for proof of my geekbench score: https://browser.geekbench.com/v4/cpu/13853828
That was before I expanded the RAM, but the score didn’t change with the extra memory.
Is your suggestion here that google be barred from monetizing android? That goes well beyond anything having to do with anticompetitive practice.

If you choose metal containers because you think plastic is bad, remember that all aluminum food and beverage cans have plastic liners which usually contain BPA or other endocrine disruptors.
Thanks, but I was actually wondering more about the apparent time of the flare (say, peak brightness since as you say the duration changes) based on the observer's speed.

Say we're both on Earth 26,000 years ago. You stay on Earth and I shoot off at C/2 in a direction away from the SMBH. You wait 26,000 years and then see the flare. How long do I wait in my own reference frame before I see the flare?

My guess intuitively is that time dilation and the extra distance cancel out and I still wait exactly 26,000 years (no matter how fast I go), but I'd have to dig out my old physics textbook to figure it out properly. Also, what happens if instead I shoot off towards the SMBH? Or at 90 degrees? I'd obviously see the flare sooner in my reference frame, but how much?

It seems like there's a general rule that, by moving, you can decrease the time until you see events (at least those communicated by light) but you can never increase it.
It would be. But the issue is so emotive and political, that in my opinion, I don’t think that actually happens very much.
I have read other studies by Dr. Angelika Doetzlhofer, and she is brilliant. I am heavily involved with disability law, and have had two very close associates who have received treatment aimed at inner-ear hair stimulation for balance issues. The study of molecular impediments to mammalian hair cell regeneration could not only change lives for those who have hearing loss, but also for those who suffer from balance issues. Thank you for the share!
This is awesome, great work! One piece of feedback is that currently all of the components seem around designing static components. I'd love to see support for lists, dropdowns, etc, and ideally with the accompanying connect code to wire up a store with the renderer
I think the state you're in might matter for weed, but from what I'm seeing from other people in this thread I highly doubt the TSA will ban them. Sounds like the FAA list is separate from the TSA list and such.
They're not going to care a bit, just like they don't go around checking that everyone's phones are in airplane mode.
I guess it could work if You never leave the university's campus.
Yep. What you describe would be the expected behavior over a high-latency, but otherwise unloaded, connection. However, I'm wondering now: In the case of an ssh session over someone's fully-loaded typical home Internet connection, might it be a mixture of both? Especially with buffer bloat and lacking any traffic shaping, can I expect that each individual packet (which can be reasonably mapped to a key press in interactive sessions) is queued right after the previous one? Assuming many many packets waiting for egress without any prioritization, when each keypress packet actually makes it out vs. any other will essentially be random, no?

The reason that there's a naturally negative interest rate isn't because "people are getting better at saving". The reason there's a naturally negative interest rate is because over half of the American population owns less than nothing; they have more debts than assets. Investors simply own too much wealth, and the general public owns too little. The economy is so lopsided that investment is yielding a negative rate of return, because the wealthy invest the majority of their money while the poor have to spend it just to survive, and a lesser and lesser proportion of wealth belongs to the poor.
Not sure making your mobile product bigger and heavier, just to cover the rare case that your batteries blow up, represents good engineering priorities.

Instead of putting in the effort to engineer removable batteries, maybe Apple could instead put in the effort to engineer batteries that don’t blow up.

Is there less plastic though (due to the rigidity provided by the aluminum)? Also, does the plastic typically separate from the metal and get into the environment, or does it stay with the metal until recycling (in which it gets burned away when the can is melted)?

Right, but the distinction we're making upthread is not Intel vs AMD, it's consumer CPU vs server CPU.

You can get out-of-band management with Xeon motherboards, or with Epyc motherboards, but you're likely not going to get a motherboard with out-of-band management with a Ryzen CPU or a Core i[3579].

I don't believe Google has a moral obligation to send traffic to the sites that appear in its search results, any more than a book has an obligation to be bought or borrowed from the library by the readers of a short quote from that book in another book. So, for me, it is a moral question as well.
It depends on how badly you want to drive "growth".

If you have $1000 today and can either spend it now or put it in the bank and withdraw $999 a year from now, what would you do? I suspect some would spend it now.

But what if that number goes down to $990 or $975? More and more people will be willing to spend it now instead of savings therefore "growing" the economy now.
Why does it have to be yet another app I need to install? This can easily and better done on a website
