Kelly and Zach Weinersmith discuss space elevators in their book Soonish. The summary of the downsides is:

* If would need to be the most precisely engineered thing we've every produced just to stand a chance of being good enough.

* Because of that, it will be particularly sensitive to wear and tear. How the maintenance would work is an open question.

* It will probably attract terrorists like crazy.

* It needs to never get struck by lightning. It is a particularly attractive lightning rod.

* It generally should avoid bad weather. Whatever it is attached to on Earth needs to be able to move. When moving it you have to avoid not only the bad weather but everything in space, too.

* If the cable breaks, bad things could happen. Bad things can range from burning up in the atmosphere to it whipping around in space damaging satellites, or anything else.

Nothing you do will prevent a snapchatting driver from crushing into you.At that point I am sure you will observe with interest how a neural network deals with the situation.
In this context it means that it's easy to make changes. As in add new functionality.
Sure but that could never be the main view. It goes too extreme in the other direction. Which is great for some use cases. But the mainstream will want things like search, categorisation and even images.

So while a "lite" view is good, I'd like websites to improve their main views so they are fast and work well with screen readers and other assistive technologies.

We have the technology, if not the will.
Exactly. The same “end user” problems recursively repeats. You just think of other (or future) developers as the end users, and those actual user requirements you can’t predict, that ends up meaning you also cannot predict what the developers flexibility requirements will be either.

You end up “making your codebase flexible” in all the wrong ways by introducing abstractions, interfaces, and extensibility designs that end up being the wrong tool for the job once the future requirements are known.

There may still be a simplistic, high level where you can have certainty about how to factor code. E.g. separating front-end and back-end, using tests as scaffolding for helping verify deployments and facilitate changing code, using a few simple tricks here and there to reduce boilerplate or make sections of code reusable.

It’s totally fine to pursue these optimizations, especially if they are part of a healthy backlog process to prioritize them.

But the problem creeps in when principal developers or “philosophizing architects” take it as a goal unto itself and begin trying to mandate it all the time, especially with the anti-pattern where huge architecture discussions become synonymous with routine “just get something done that works and refactor later” code reviews.
Harmless, except for the passengers.
RAM is only cheap if your consumer can actually run your product. As manufacturer's have decided 4GB is good enough for most people... Maybe the developer is the problem.
I don't disagree with anything you've written. The only thing I'd take issue with is placing NHST at the feet of statisticians. Scientists deserve a fair share as well. :-p
My father and ex husband were both career military. I addressed a person who also served in the American military.

You don't own this entire thread because you spoke in it. I'm quite open about my background. It should hardly come as a shock to you that I don't agree with the idea of personally vilifying military members because you personally disagree with the politics of their country.

Anyway, I'm done, regardless of whatever else you want to say here.
A couple of concepts core to the serverless model is that components communicate via API, and that resources are consumed on demand. Traditional RDBMS don’t really fit into that model. Google Spanner is the only thing I’ve seen that seems to come close. AWS doesn’t have much aside from Dynamo, especially considering how poorly lambdas perform when you put them inside a VPC.
Also, the value of gold doesn't go to zero when the electricity stops... if/when that happens the chickens laying eggs in your coop will be worth more than bitcoin.
The problem is how you keep the tether from dragging behind the orbit when you do that. Space elevators require a fairly delicate balancing act to keep the mass directly over the base of the elevator, otherwise they turn into giant slings.
I get your point but I honestly think the people planning the second Iraq war really didn't care about casualties, or perhaps we're just badly deceiving themselves. "We will be greeted with flowers" they said. "the war will pay for itself" they said.

Specifically I think Cheney was willing to spill as much blood as needed. Some of his supporters in the media probably we're just in denial about the full costs of over throwing a country as large and fractious as Iraq.

What this implies for future wars I'm not sure.
At least we now know the cabin dimensions with a precision of two significant figures.
Space elevators can be used this way because once the tether goes beyond geostationary orbit the tether is going above orbital velocity. Go far enough and its above escape velocity. So you just drag a probe out far enough and let go and it will escape the gravity well.
One might think that, except that Advanced Scientific Concepts, which Continental bought, has had it working for a decade.[1]
Their units work fine, but are expensive. They're mostly sold to DoD and used for space applications. The Space-X Dragon spacecraft uses one for docking.

There's a tradeoff between field of view and range. Automotive systems will probably include a long-range narrow field of view unit and a shorter range wide field of view unit.

Flash LIDAR has some advantages. No moving parts. Can be fabbed by semiconductor processes. The one big laser is separate from the sensor array, which helps with cooling. Also, you can spread the outgoing beam, which helps with eye safety. (Eye safety involves how much energy is in an eye iris sized, 1/4" or so, cross section of the beam. If the beam is spread out, energy density is lower.)

But you can’t make it equally easy to add in every type of functionality. For any type of extensibility design you bake in, some other types of extensibility now become harder.

So “making it flexible” hinges entirely on whether or not you can correctly forecast exactly which types of flexibility you’ll need. But this is no easier, and often harder, than predicting how end user requirements might change in the first place!
Thank you! We homeschool and use a “classical” program focused primarily on grammar, rhetoric, and logic. Resources like yours increase our children’s access to classical literature while helping us reduce book costs (which can be surprisingly high).
Why is this better than separate LIDAR and camera?

Because you're collecting NIR ambient light, your optics are wideband. Meaning that daylight would have a more pronounced negative effect on system range (easier to saturate the photocells). It's also low resolution (as most LIDARs are), and there is no color segmentation data.

In an automotive application, I can't see a justification to unify both visual and LIDAR into a single sensor, rather than having an extrinsically calibrated array of sensors. You can improve the calibration out of the data over time if you're very concerned about system stability.

It seems like a nice party trick, but the vehicle LIDAR game focuses on solid state long range units, as this will be what gets into mass production. The visual band imagers in the car are a given for many other reasons anyway.

Well yes, if they used a completely different machine...if they had a $250k machine instead of the hobbyist one.

On the same basis what if they had a custom gear saw, with a specially shaped cutter that could slice a single tooth on a stack of 50 cogs in one pass ....

But I thought the point was to compare two lower end machines and their capabilities? And if so the cnc was not the outright winner, no matter how cool it looks to tech geeks

From the CFG perspective, try..catch is strictly weaker than goto (you can't build irreducible control flow with it for example). And, I mean, any return is basically a non-local goto for which the destination is unknown at compile-time.

Your story seems strange since I think one of the best features of exceptions is that if you don't catch them, you always get a full stack trace which is a great boon for debugging. If you bubble up error returns, the only contextual information you get about where the error occurred is what every caller attaches to the return. But I have had terrible trouble getting stack traces (or types) from Python exceptions when they cross a process boundary so maybe that's it.

(I have no strong opinion about whether exceptions are good or bad myself.)
The service could be stateless.
I used to see future proofing all the time in boring corporate jobs. One example I saw multiple times was complicated "generic form builders" where the dream was users would be able to add their own forms quickly and easily. Then 5 years later the whole app would be say 10 screens, but maintenance was a nightmare because under the covers everything was poorly abstracted and generic.

I also saw lots of "split it into microservices so we can scale out for load" on systems that years later still only saw minimal use.

Fiat (in the current context) literally means "by government decree".

I believe what you mean is that modern currencies (and bitcoin) aren't backed by anything other than pure belief they hold value as opposed to their traditional backing by specie or bullion.
What's the power output for the unit in the paper?

I thought this out some more, and came up with an idea for a garbage-collection satellite.

The most obvious idea is to launch each satellite, have it collect garbage until it is full, and then fire a retro-rocket to take it out of orbit so it burns up on re-entry.

The problem with that plan is the large and exspensive garbage collector gets only one use. I think it would get you a lot more bang for the buck if the garbage collector has a bunch of folded bags, each with a small solid fuel rocket attached. It would unfold a bag, fill it up, then release it and order the attached retro-rocket to fire and take it out of orbit. Then it would unfold the next bag, and so on. In fact, maybe when it ran out of bags you could send up a resupply satellite.
yes throwaway accounts evade the shadowban
Yep. Some of my favourite programming advice is that the easiest code to change is code you haven’t written yet. In other words short, straightforward code is always the easiest code to adapt to new requirements.

I like the comments about how public ownership and operation of public transit works in Europe. I'm curious as to why, and I have some ideas:

- private ownership of automobiles in the U.S. took off
much more than in Europe
- the States did not put much emphasis on public transit
- the States invested in roads
- so Americans have long had an alternative to bad
public transit: just drive
- European countries put up a lot of impediments to
private automobile usage: high taxes, limited road
investment(? guessing on this one)
- so the cities had reduced incentives to providing
decent public transit, unlike Europe, where bad public
transit would have been fatal to many political careers
just due to the lack of alternatives

There's also the fact that geography meant that private automobile usage in the U.S. had to be higher than in Europe...

Maybe that's all wrong. I'd like to hear what others have to say about this.

There are also intermediate steps before outright attacks: simply having drones which can track people in a crowd, guide ground forces, etc. has a lot of applications which wouldn’t be publicized (“officer smith recognized the resistance officer in the crowd and followed them home”). Plant some DL fakes on their phone and occupation could be very different.
Silicon Valley is not dying. It is the city (infrastructure) that has failed to grow SV. Instead, the prices went up.

"...defensive technology always lags offensive technology. So you know, the cancer moonshot I would propose is dual use, just like nuclear weapons and nuclear power, two sides of the same coin. The ideal cancer treatment someday is going to be the doctors biopsy your tumor, get a sample, send it down to the lab, the lab will figure out the genetic signature of your exact cancer tumor. Then somebody will build a virus, that using that if-then statement, only targets the cancer cells in you. They'll put that virus inside you, you'll feel like you have a cold for a few days, the virus will go to work destroying your cancer, and then you'll wake up cancer free. That's a pretty good deal, we all want that to happen.

But notice this exquisite targeting overcomes that big drawback against bioweapons. So the new technologies are going to allow incredibly targeted bioweapons. So think about three different axis. Who might you target?...you could also target a family, like the royal family. You could target a group of people, or an entire species."

He goes on to describe examples of what he asserts will be possible to do, which is target virtually any identifiable characteristic among a life form, or cause practically any sort of deficiency or alteration within cells.

He also points out that Biotech is currently outpacing Moore's Law, and this technology will likely become extremely cheap extremely fast.

I'd give some of them to open some paywalls, but not to the economist if they continue to write such vacuus articles.

Maybe give them to open the paywall, then be able to relinquish that payment after having consumed it and it was of low quality.
It's better because there's no need for calibration, you always have perfect calibration.

Solid state lidar has issues. The cofounder of Ouster, Angus Pacala previously cofounded Quanergy, a solid state lidar startup.
once robots get more capable

There’s a common misconception that robots are not yet capable enough. This obscures the present, unexecuted, reality.

It is well within the budget of many nations to build grenade carrying swarms of drones capable of autonomously patrolling and attacking human targets. The fact that we have not seen this on a wide scale has no bearing on present capabilities, or that which is within reach. If you search YouTube you can already find examples of ISIS using remote piloted inexpensive drones to attack armored targets with devastating effectiveness.

This is here, now.

As a former light infantry grunt I have a visceral feel for the breathtaking transformation of the battle space we may soon witness. Within an AO it is very challenging to deny access to light infantry, even in the most foreboding terrain. Autonomous drones can and will effectively deny infantry access to large areas. This fundamentally changes ground warfare, even guerrilla.

Use logic. Can a drone recognize someone holding a weapon? Can a system be devised to demark areas of friendlies? Are all nations as cautious as the US when it comes to each weapons release?
Nope.

It just wasn't really that good.

Is it strange to anyone else that the more you spend on the homeless, the more homeless you seem to get?

Why does San Francisco have more homeless than Houston despite Houston being far bigger? We could argue housing costs, however many homeless in San Francisco aren’t even from the area, they gravitate there, in my opinion, because of permissive policies. San Francisco’s homeless problem is among the worst in the country, with Portland and Seattle quickly closing the gap. Less “progressive” places seem to have a much lower level of homelessness. Camping on sidewalks, shooting up, and shitting in doorways is rarely tolerated in most other places in the country, yet at least we’re working to stop plastic straws!

It might seem that San Francisco is more apt to arrest smugglers of plastic straws long before they arrest those shooting up in public and tossing their needles on the sidewalk. You are more likely to get fined for a polluting car than you would for smashing the windows of that same car.

> choosing to see literature through the hateful lens of power dynamics robs you of the change to see this beauty.

I enjoy selected classics quite a bit, and I've studied them in depth. One of my favorite pieces is Beethoven's Waldstein Sonata, and I can talk about it in the context of evolution of sonata form.

I also know my Duke Ellington and my Joni Mitchell, my Stevie Wonder and my Beatles -- all of which are similarly regarded as unassailable classics within certain circles of devotees.

An appreciation for the classics is completely compatible with the conviction that they are not "timeless universals", but that every last one of them is a product of a specific time and place. And the clash between canons is in fact a disgusting political and cultural power struggle.
Lots of talk about fiction books here, but what are the classic nonfictions?
I think reflection on the course of one's decisions is a great property to have, the answer 'have you heard of 9/11' speaks volumes. That's why I believe that joining the military is a path fraught with peril, essentially you will be conditioned to follow orders and you then need to hope that those orders will result in a net positive where you will end up holding the bag if they don't.

What your father and ex husband did for a living is your problem and has no bearing here because I wasn't talking to either of them, and I take it that unit91, just like me is perfectly capable of articulating his own thoughts on the theme.

If you take each and every question of members of the US military asked as a 'personal vilification' then the problem is on your end. After all, each and every one of us has a personal responsibility and we have a collective responsibility. The military is - or rather should be - used as a means of last resort and to willingly enlist into the military for a country that has at best a very questionable reputation post World-War II regarding the conflicts it engages in is a pretty special decision all of itself.

The question of whether or not someone has ever thought of themselves as the bad guys is perfectly valid, even if you personally don't agree with it, after all, I can't ask 'the country', but I can ask those who identify themselves as being part of the military simply because it interests me.
The center of mass of the cable-counterweight system orbits at geosynchronous height. Also, the gradient of gravity will Stabilize the attitude in the desired orientation.

None of this should be construed as an endorsement of space elevators, though. They will never happen on Earth as it exists now. Over and above the material science, you have to clean out LEO of all satellites before you even start construction. It’s just a really dumb idea all around.
yes it is possible but recognition as such would be an issue.

What about insights into human nature or how to live well?

They may not have cared about losing lives when they invaded but the American public quickly got sceptical about the war once they realized that their soldiers were getting killed. I think this definitely put some restraint on further military action.
