I always wondered how those Mars rover selfies manage to not show the arm holding the camera.
They can take photos that look as if they were taking by a separate camera but they just move the arm at which the camera is attached around. The arm will be at different positions in different images and they then stitch the photos together excluding the image parts with the arm.

Edit: I found an animation for you that actually shows the process! It's on NASA JPL's Instagram account, though: https://www.instagram.com/p/6k4pUMFbys/

Because it's a 28-year-old game with the computational limitations of the time. It does not simulate people walking. It does not simulate multiple types of buildings existing in the same plot. It does not simulate building styles (I think?). And it has nothing to do with ideology. No-one could make such a simulation in 1993.
Streak (YC S11) looking for a senior front end engineer (remote only)
As mentioned in the article, it's easy to mitigate by not only checking that the request is arriving at your endpoint from an official CF IP, but to also check that it does not contain a CF-Worker header (or contains one with your domain).

The limits on workers' sub requests (e.g. requests are done by host name only, can't use IPs with a different host name) make it somewhat cumbersome to set up reverse proxy workers (which was my use case), but the tech itself is just great, works very reliably and the delay, while noticeable, is tiny and never bothered us.
Since this is 2021, you should use IPv6, which doesn't need NAT.

A 2018 model 3 or X might be a sub-$5K (in 2021 dollars) car by 2030. If they are, very few batteries will be replaced in old LEAFs. The faster that new EVs mature/evolve, the less comparative value older ones have meaning they will be getting scrapped when the next battery replacement is needed.

I do all the maintenance on our cars (ex- tires, body, and warranty/recalls). The LEAF has already had one battery repair under warranty (at around 17K miles, out of service for several weeks and likely a $2K+ repair at future independent rates-was 2 techs for most of a day plus pages of special sealants and consumables)

Other than that it has needed wipers and windshield fluid and that’s it. If that pattern keeps up, they’re still headed to the scrapyard en masse, I think.

> There are lots of things driving for crypto besides speculation though.

Like what? I mean aside from crime.

E.g. the "Venezuela argument" has been debunked, from my reading.

In my own life I've seen employees ask to be paid in bitcoin, because of the large fees involved in getting your salary and transferring it into Brazil.

So… those "fees" are mainly taxes, and not paying them is illegal.

To steal manned argument I guess is that some people actually do want to buy stuff online without a third party knowing who paid whom.

First of all BTC is terrible for that. But second, most people don't care if a third party knows they bought pizza. Especially since the pizza place still knows, and they need to keep records anyway, because tax laws.

Fourth, if they don't keep records then they can just say you didn't pay them. They can say "oh, that was not our wallet, you must have mistyped".

Fifth, if the pizza has poop on it you can't even reverse the charge.

Sixth, every pizza place will now be a money laundering scheme.

This is not what we want as individuals, nor as a society.

But yes, some people do want to buy a pizza online and not have a third party know. It's basically LARPing.

Buying a house or a car anonymously? That was made illegal on purpose.

Buying a big mansion anonymously? Well that's clearly at the very least tax fraud.

Anyway, I truly want to hear about any legit use case for cryptocurrencies that is not just LARPing, because as far as I've seen nobody in the 12 years since bitcoin launched has come up with one that actually makes sense.

> Suggesting cryptocurrency supporters are sociopaths is quite simplistic,

Yeah, it is. It's like the old expression "it's very hard to make someone understand something when their livelihood depends on them not understanding it", or something like that.

https://www.youtube.com/watch?v=hn1VxaMEjRU

But the amount of rationalization from cryptocurrency proponents I do think is sociopathic.

> and overlooks the majority who are not involved in anything like this article discusses

When you're in the mob you're still one of the baddies, even if you're not actually the one murdering.

I do blame every cryptocurrency supporter. They are complicit in making the world worse for their own profits. They have a moral obligation to recognize their supporting role in this, and to stop it.

Thank you about the Onkalo site. I didn't know about it. Do you know if Russians have anything similar planned closer to Europe, in the Oural for example (iirc the oldest geological region in Europe) ? I could only find Krasnoyarsk on the web.

On your other info : I don't know about culpability. I'm passing the 40 year old mark, and I don't remember my generation, or the generations right before mine having enough influence on such matters until very recently.

These choices were made much earlier, by within your framing I'd say more culpable age brackets, and which are slowly let's say "disappearing".

What remains, in my opinion, for people currently in charge of affairs, and in the future, is a matter of responsibility to all future generations. We most certainly know what's what now, and the ethical and moral calculus is publicly in evidence, as a consequence of, amongst other such operations, the Greta Thundberg UN tour.

Again, not arguing against nuclear. If we do it, I'd say let's not create new problems out because we're too sure of our probability projections... As pointed elsewhere, we were due for an Ice Age. That might still happen down the line, whatever happens to surface human politics. Let's make sure somebody's there to check for such leaks down the line, and that it's easy to access.

Once we decide we won't make matters worse now, why stop at that ? Let's make sure we don't make them worse down the line out of some new error.
I do. Moral and ethical relativism does not protect you from having to stake a claim on a set of thoughts and values and standing by them.

You're more than welcome to think not of course, however this is definitely a more common thought than not. There's a larger shared set of values that people tend to hold even if it's not objective and I think you'd have to go to great lengths to prove me incorrect regarding those things being good to the majority, and even greater lengths that the opposite thought is good at all.

It's embarrassing that they don't provide a metric conversion, and also omit the ° sign.

Kudos to AMD for looking for, finding and then publicizing this themselves.

And of course another plus is that we don’t have some vapid detail-light brand-heavy vulnerabilities-need-a-name website popping up too!
Behind the scenes, they're very likely using metric. For press releases and such, however, it's worth remembering that the primary audience is the American public, and said public - for better or worse - uses those antiquated units.
Not to detract from the point but I find Cloudflare to be on the more reasonable side when it comes to blocking Tor. A lot of sites end up effectively banning all Tor IPs, Cloudflare merely requires CAPTCHA. And they do offer Privacy Pass as a sort of approach to make it a little less annoying.
That's not an artificial scenario, it's the scenario that would happen if proof of space took off, people would have a financial incentive to use storage space.

> if that case ever came true, the total energy waste would still remain less than PoW by orders of magnitude.

Yes less ongoing energy use, but it does reward creation and effective waste of hard drive space, which isn't without environmental knock-on effects, both some energy use and for chemical byproducts etc.

This is not an 'extremist rationale', if you give people a direct financial incentive to get as much storage as possible, what do you think would happen?
> "I disapprove of what you say, but I will defend to the death your right to say it."

People say this, but I've never seen it. Free speech absolutists weren't out there defending protest rights, lgbt activism, or union advocacy. The speech rights of the powerless have been consistently crushed by the powerful while the first amendment is used as a power defense of those who seek to harden existing power structures.

This quote often feels like a justification to support the speech rights of bigots while dodging the question of moral responsibility.

> Cloudflare merely requires CAPTCHA

I do agree that Privacy Pass is in theory a good idea, although to say that CloudFlare "merely" requires captchas to be filled out is a bit disingenuous. You're often required to complete 5-10 captchas, and sometimes even after that, you get denied. Had that happen to me multiple times.
And I think the Cities Skylines model is the way to go here, although consuming computationally. I read somewhere that they were being used for city planning exercises at MIT and in Sweden.

What is a violent threat? Why is it taken as an axiom that this is where the line is drawn for free speech? I am personally less concerned with individual violence than with political violence enacted by hate groups who gain legislative power.

For a long time, gay people could be thrown in prison for having gay sex. This was mass violence against gay people. It was absolutely within free speech rights to advocate for these laws and to vote for legislators who supported these laws. This, IMO, was far more violent to the gay community than an individual saying "let's go kill that f*g". So I question whether "violent threats unacceptable, hate speech acceptable" is the right boundary.

You don't understand depression, and you are not qualified to make suggestions to people with depression. Please stop.

We are talking about people who find it hard to get out of bed in the morning, and to motivate themselves to do the most basic tasks, let alone putting on clothes, going out, possibly going among people to ride public transport to where the nice trees are. Ugh. Also, the season/weather might be all wrong for enjoyment outside. Also, even temporary enjoyment outside might not cure a medical condition that you obviously do not understand.

It doesn't have enough energy for that, precisely my point.

Wireless beam forming demands a multiple antenna/DAC activation energy (even if just "listening" RF) two orders or three above the energy harvested for the muC as cited in these works.

Even if we want to say schedule things correctly, it's very difficult in practice for commercially available muC's to keep accurate timer without skew in very low power modes for the once-a-day reactivation which will eat 99% of your condensator energy.

If such a low activation energy specialised transceiver antenna exists commercially, I shudder at its price.

And then of course the packet emission could fail to be received at that precise moment for any number of reasons. Beamforming is a high-power, high bandwidth, always-on high-computation sport, AFAIC.
Right now most population models suggest we'll see growth flatten within decades, and peak within a century.

It's not really an open question - it would take reversal of long lasting trends in large parts of the world to do more than at most delay the reversal.
> Egypt nationalized (stole) the canal

Nasser paid full compensation for shareholders based on the share price of the company on the Paris Stock Exchange, as he had said he would before the nationalisation.[1] So this was not much different to the nationalisation of companies in the UK that had been happening around the same period,[2] or to the compulsory sales that happen even now in the US.[3]

Sure, but I'd have to grant you anything other than the human perspective matters most first and you've already assumed it does where as I remain unconvinced. You made a pretty out there statement and I provided what is in all likely hood the common opinion.

I think the burden is on you here if you want people not to believe humans, of which I assume you and I are a part of, and our perspectives matter the most.

Until the coral reef learns to speak up and say, hey I'm putting my foot down. Humans and our choices determine it's continued existence. That alone makes our perspectives the most important if you want to continue having a coral reef, because it's our perspectives you'd need to be changing to keep it around.

SimCity 4 doesn't simulate individual agents. You can blatantly see vehicles phasing in and out of existence to give the look of a bustling city, without actually simulating one.

SimCity (2013) is the first SimCity game to simulate individual agents. And it takes some pretty ginormous liberties there, too. Citizens, for example, return to any random available house after their workday. That is, they switch homes every day. It's less human city and more... anthill.

Well, that was probably predictable. If the news coverage of her being the "first female ship's captain" happened near the same time as the Suez Canal incident, those two stories can easily be conflated into a "told you so" narrative to justify condescension towards women aspiring to be ship's captains.

It doesn't matter whether the correlation is real because the narrative feeds into existing stereotypes and anyone peddling it confronted with evidence to the contrary will just say that while it may be factually untrue, it still carries some underlying truth and that's what matters.

This is just a microcosm of why "fake news" has become so widespread on social media.

This just sounds like a way to make a proxy with Cloudflare workers, which aren’t considered by Cloudflare’s filters to be as suspicious as Tor yet. You could do the same with any new VPS/cloud function provider. Am I missing some actual bypass?

If the X-Forwarded-For value from the request is forwarded by Cloudflare’s proxies unaltered, giving special privileges to Cloudflare workers, that’s a problem, but it’s not clear whether “a site who display your headers” is protected by Cloudflare and displaying an unaltered X-Forwarded-For. I don’t expect Cloudflare to have made this oversight, and the e-mail response from them matches: “All workers subrequests go through Cloudflare again, and therefore you won’t be able to bypass any restrictions directly.”
