Mistake #1, the idea of a "risk corridor" applies to an object in a decaying orbit. It will hit somewhere along the line of orbit. But for an object coming from out of orbit, there is a center of where it is likely to hit, and then a bell-shaped curve across the cross-section of the Earth for where it might. Basically half the world is at risk, with some areas at higher risk than others.

Mistake #2, objects that we find which could hit us get within range of our rockets only a finite number of times. For a previously unknown large object with a several year returning orbit, that finite number is likely to be 2 - once when we found it and once when it comes back (at which point it is too late). A more realistic version would be that it is on a long trajectory that will hit Earth after 3-4 times. Which gives us a lot longer to prepare, and a clear timing on when we want to try to hit it.

I won't comment on the cultural mistakes. Except to note that "We're going to get hit but odds are good that it is over water and nobody gets hurt" might be less panic inducing than the story claims.
>USPS and hybrid shipping options can be relatively cheap, for domestic shipping.

Actually, they really aren't, not for private shippers. If your item is tiny, you can ship it for around $3 by 1st class; if it's over 1 pound, it's not going to be cheap. For something that only costs $5-10, that's very significant.

>You could always offer multiple-item discounts at that point.

People look at initial price first, and won't see your discount until later. The competitor with a cheaper per-item price will get the sale.

Go is awesome programming language, since it is simple, readable and provides good tooling - code verification (vet), code formatting, testing, benchmarking, tracing, race detector, profiling - out of the box.

Go encourages writing simple straightforward code without complex abstractions. This improves programmers' productivity, which allows writing raw practical code instead of spending time on theoretical design patterns, inheritance hierarchy, generics, fancy algorithms, monads, "zero-cost" abstractions (with high mental cost), borrow checking, etc.

That's why we could write fast time series database in Go from scratch in less than a year - https://github.com/VictoriaMetrics/VictoriaMetrics/ .

I'm of the opinion that this sort of thing is not any different than reality TV highlights or celebrity news. It's all mostly useless information that feels good going in but doesn't add much value int he end.

Neil Postman touches on this in 'Amusing Ourselves to Death' - here's a nice quote that gets at how I feel. Although he's talking about the telegraph and photography, I think it applies well to the internet and video.

"In a peculiar way, the photograph was the perfect complement to the flood of telegraphic news from nowhere that threatened to submerge readers in a sea of facts from unknown places about strangers with unknown faces. For the photograph gave a concrete reality to the strange-sounding datelines, and attached faces to the unknown names. Thus it provided the illusion, at least, that "the news" had a connection to something within one's sensory experience. It created an apparent context for the "news of the day." And the "news of the day" created a context for the photograph. But the sense of context created by the partnership of photograph and headline was, of course, entirely illusory. You may get a better sense of what I mean here if you imagine a stranger's informing you that the illyx is a subspecies of vero miform plant with articulated leaves that flowers biannually on the island of Aldononjes. And if you wonder aloud, "Yes, but what has that to do with anything?" imagine that your informant replies, "But here is a photograph I want you to see," and hands you a picture labeled Illyx on Aldononjes. "Ah, yes," you might murmur, "now I see." It is true enough that the photograph provides a context for the sentence you have been given, and that the sentence provides a context of sorts for the photograph, and you may even believe for a day or so that you have learned something. But if the event is entirely self-contained, devoid of any relationship to your past knowledge or future plans, if that is the beginning and end of your encounter with the stranger, then the appearance of context provided by the conjunction of sentence and image is illusory, and so is the impression of meaning attached to it. You will, in fact, have "learned" nothing (except perhaps to avoid strangers with photographs), and the illyx will fade from your mental landscape as though it had never been. At best you are left with an amusing bit of trivia, good for trading in cocktail party chatter or solving acrossword puzzle, but nothing more."

Debian GNU/Linux port for RISC-V 64-bits: Why it matters and roadmap
My experience in North Texas is that malls aren't so much going away as they are concentrating in a small handful of locations.

We lost or are losing a bunch of malls, but there are also a small handful that are thriving. Prestonwood, Valley View, and Collin Creek may be dead or dying, we still have Stonebriar, NorthPark, and the Galleria doing very well. There are fewer malls, sure, but the ones we have left are thriving.

Of course, Dallas is one of the most thoroughly suburban parts of the country. Sure, there are a small handful of people moving to places like Uptown or Oak Cliff, but the northern suburbs are still booming, and almost everyone I went to college with who's still in the area either lives in a suburban apartment complex, or if they're financially successful, bought a house in the exurbs. And even if a good chunk of twentysomethings are moving to the city, there are still all the teenagers living with their parents in the suburbs. And for that matter, there are twentysomething adults who are living in the suburbs with their parents because their careers haven't taken off.

I had the opposite problem. When I lived in a condo previously, I had the poor luck to live next to a shitty neighbor who would have parties at 5AM on Monday morning because she didn't work. The fact is anyone can get unlucky and have a shitty neighbor, but at least when you rent if the hassle is bad enough you can much more easily up and move.

We sell customized products. A little over a decade ago, we noticed a few orders going out that were not at all customized or were customized in a way that suggested the customer wouldn't be happy when they got them. We tracked down the account (based in NYC) and they'd been ordering products about every 45 days (mid quarter and end of quarter) and they'd never complained nor asked for a refund.

Seems they were after the shipping identifier, as when we changed the shipping identifier to not leak shipment volume information, the orders soon stopped.
Or would they just use the kinetic energy of 4000 lbs traveling at 25-60 mph to accomplish the same thing, like in Paris? I don't know.

After you saying "conflating things that are not related" you hand-wavingly compare "young white disillusioned males" shooting up a school with .. a 37 year old French-Tunisian on a watch list of authorities, pledging allegiance to ISIS and driving a van filled with explosives into a crowd.

That is not "accomplishing the same thing" or in the same way or by the same people.

Find a "school shooting" equivalent - after all if that was equivalent it ought to be happening already in USA even with guns available, oughtn't it? More high schoolers have access to vehicles than guns right now. How can you say "I don't know" if it would happen when it .. is not happening?

I don't see it that way. I have been severely burned-out, and will never let that happen again. I have also been visited by the Black Dog. They are different. Perhaps both present in some people, so maybe hard to tease apart.

The cure for burn out is to cut out any activities that do not bring personal joy and satisfaction. (My burn-out was cured by a few months off pursuing my hobbies. Yes, I was lucky to have that option.) The thing about depression is that nothing brings joy or satisfaction. Burn-out and depression are orthogonal. But IMO you must cure depression first, before trying to address burn out, if both are present.

I thought this business has technology cycles. It's just that AMD has missed a few and now Intel is at the mid-stage of it's current architecture.

Cutting pricing on a product-line that is in mid to late life-cycle is expected in most other businesses including technology.

There are other arguments wrt Intel not being fabless that I get but those are not the same thing.

>Lithium-ion specific energy density < 1 MJ/kg

i think battery swapping is much more realistic for planes than for cars and that would allow to use non-rechargeable or factory rechargeable batteries like the metal-air ones (my favorite is Al-air) which is order of magnitude better than rechargeable Li-ion, and that really gets us close to the gas/jet capabilities given the low thermodynamic efficiency (or extremely high price and complexity) of the combustion based engines.

Self launching on batteries means carrying around a fair bit of dead battery weight for the entire flight. Electric sustainers (can't take off but can stay up) are pretty interesting because gliders take hardly any power to fly level. Example:

All this electric vehicle technology works really well for electric glider winches. You can get a whole lot of peak power off of a battery so you don't need a huge electric power feed.
I get full OS freezes periodically and it's the only thing keeping me from switching, really. It usually unfreezes after anywhere between 10-60 seconds. But mouse won't move or anything during the freeze.

It's on Windows 10, Nvidia GPU. Have tried the bucket list of things to solve this without any solution so far. It happens even with just two or three tabs open.

I believe it boils down to this unsolved bug, at least in my situation. I do need to profile it myself if I want to know for sure though:
https://bugzilla.mozilla.org/show_bug.cgi?id=1501281

It only happens with Firefox, nothing else. All other games, programs, browsers, etc run without issue. Firefox is the only commonality that causes the freezes. If there are no Firefox processes open, the freeze does not occur.

Oddly, I see you're on macOS, where I also used Firefox- but I never had an issue there. Interesting, because it seems my experience is the reverse of that of most Firefox users.

That article points out that "front running"(which it isn't) by HF may cost .2% a year. Its probably less than that. Bid/ask spreads are often around that percentage. This is just a trading cost. Nothing nefarious is happening here. The spread may go up if a large fund is buying, but this is only natural due to supply and demand. These HFs are just providing liquidity and "charging" a small fee for doing so. If nobody did this, trading costs would probably be even higher. There is extreme amounts of FUD about HFT and market making for some reason.

Now about the Russel indexes - the article has a point there. They are notoriously shitty indexes. Nobody should be putting money into those. But still - nothing illegal(nor should it be). This is yes, clearly a case of "investors' fault for acting irresponsibly". Nobody is forcing them to use these indexes and this information isn't hidden anywhere. Last thing we need is 100 more regulations.

> The cure for burn out is to cut out any activities that do not bring personal joy and satisfaction.

That, and giving yourself a series of small tasks, each of which you can complete easily. That feeling of satisfaction that you obtain by completing these small tasks quickly turns into your emotional ability to complete bigger and bigger tasks, and before you know it, you're back on the horse. It's amazing how effective this is, it's been documented here before too. I'll see if I can dig out where I first read this.

I feel like this is the real success of Python: the "one and preferably only one obvious way to do it" idea means that new ways of doing something are rarely added, and when new they are added, old ones are likely deprecated. Complain all you want about the 2 to 3 transition, but it's resulted in a simpler, easier-to-use language. If the community really feels a different way is better, they add it in libraries. My only criticism of Python in this respect is that they didn't take it far enough: Do we need higher-order functions AND loops? Do we need classes AND first-class closures?

I totally agree with you. Certainly there are tradeoffs to both owning and renting, and different people will find the tradeoffs stronger in one direction or the other.

However, the reason I made my original comment is I feel that so often, at least in the US, the downsides of home ownership are completely minimized (I think people usually vastly underestimate maintenance costs, both in time and money) while the downsides of renting are blown out of proportion (the "you're just throwing money away" false comparison).
Wonder what the pricing in on that location data is for financial sector customers, and if it's cheaper than a regular purchase of satellite data. It'd be interesting to compare the mobile location data to the satellite data and find the deltas— that would make it a lot easier to build efficient models w/ existing satellite if it's cheaper.
