> Third-class passage was £8, approximately $1000 in today's currency, i.e. more expensive than an equivalent trans-atlantic flight today, and too expensive for poor people to typically consider.

Desperately poor people spend well over that to get smuggled across the Mexican border today.

> A decade ago, Mexicans and Central Americans paid between $1,000 and $3,000 for clandestine passage into the United States. Now they hand over up to $9,200 for the same journey, the Department of Homeland Security reported last year. Those figures have continued to rise, according to interviews at migrant shelters in Mexico.

Being an EU migrant myself, I know the impact of all this very well. Every day I wake up hoping my parents are still healthy, because caring for them will soon be a massive problem. And still, chances are that sticking around my hometown, as beautiful as it is, would have doomed me to a much worse life - and not because it's been "left behind" in any way, but because I simply don't match the culture in very significant ways.

Obviously nobody should be forced to move. Nobody is "enforcing mobility" in Europe; they did in the past though, when Mussolini literally sold Italian labourers to half the planet and the UK shipped convicts to the colonies. The good ol' times often weren't that good. What we need is to provide all the freedom we can, and let people look for happiness wherever they see fit.

For particularly short trips I would hope that even smaller forms of transportation like bikes and e-scooters would gain some ground.

That is true. What frustrated me is that the social/cultural set up only seemed to amplify it, rather than counteract it to balance things out.

For example, in fresher's week, 'default' organized activities were clubbing every night of the week. Sports achievements were celebrated with ceremonies, pub parties, chalk drawings on the walls of the college, publications in the magazines.

There is nothing wrong with any of those activities, as has been mentioned that is just what some loud teenagers getting a taste of freedom like to do. But you would expect a top academic institution encouraging other tendencies to even out the social 'hierarchy' a bit. The very fact that 'you might not have noticed the studious ones' who were 'hiding away in their rooms' is the problem when it is happening at the top academic institution in my view.

A solar farm is capable of producing 350 Mwh per year/per acre and it takes 18 kwh to power a Tesla for a 100km ride [1], so a single acre of solar power can produce enough energy for 19,000 of those rides, or power 190 cars (10.000 km per year) just by putting a bit more than the roof of their parking lots in solar cells!

Maybe you don't need that much of a grid update at all, and even maybe quite the opposite if you consider that you car could power your house indirectly using solar power. Best case, you'd be actually the grid even less than you do with out an electric battery in your garage...

Flying noe was used in several missions in WW2, it was a known tactic so you cannot say "it only works because ...". A fast plane or helicopter flying noe is detectable, but until the people detecting it can inform the people that can intercept, the mission can be over and the aircrafts returning to base.
> The total energy usage shouldn't be much of an issue as we'll move electricity use from refineries to charging batteries – I believe these are at least in the same ballpark.

That would interesting to figure out. How can we do that?

Not all refineries will cease production. How many?
I don't think it's that far-fetched, people are already installing solar panels (and have been for a while), it's just that now you'll have a much closer need. Hell, you'll probably even be able to use your car's battery as storage for your energy needs overnight, so you charge the car during the day and power your fridge/TV from it during the night (assuming you don't need to go somewhere in the morning).

Pretty damn exciting.
Well, I guess it's up for interpretation, but for me "old internet" was when people ran their own email servers and their own domains. With that perspective, Gmail basically ruined being able to run your own email service as it's hard to get through the spam filter. Maybe it's better now but it used to be hard.

And not sure what Gmail contributed to open source, I can think of 0 projects/libraries/protocols/specifications that comes from Gmail and is used elsewhere widely. I guess that you can export to mbox via Google Takeout is something, but has very little to do with open source.
In a PR quote, some bigshot from a conventional car company said,

A slower version of the same talk: https://youtu.be/FSyfZVuD32Y
No talk about the lack of chargers and energy capacity which will be the show-stopper in most regions outside some of the most urbanized ones. Large battery cars that weigh 2 tons don't make sense for most urban dwellers who at most want to take the kids to school and back. Small electric 'cars' will emerge when regulations allow it. For trucks and other powerful cars, a diesel engine will probably make more sense.
Here's a video with a Tesla Model 3 keeping the cabin at 21 C for 71 hours in -4 C (24.8 F) weather.

https://www.youtube.com/watch?v=bpzB3RbjuHI

That car has a heat pump for cabin heat, which has a coefficient of performance of 3-4. That means you only need 1/3 of the heat energy as electrical input.

Compare that to a gasoline engine, where almost all the energy in your fuel is wasted as heat outside the cabin. I don't know what fraction actually makes it into the cabin - but I'm guessing it's single digit percent.

We Swiss people are also quite suspicious with this kind of documentation (Google Fichenaffäre / secret files scandal for reasons). To my understanding you will get this Covid certificate either through vaccination, after having had Covid-19 or after a negative test.

Also it's worth noting that the US has a bunch of nationalised/government controlled services that are privatised in the UK and other parts of Europe, including:

- Airports and airport security

- Postal service (USPS)

- Train operators (Amtrak)

- Insurance (FCIC, FEMA)

- Various municipal utilities and the TVA

- Various credit/financial/banking institutions

In the UK, we have privatised airports, mail, energy, telephony, water, train operators (though this is sort of changing), and don't have equivalents for many of the government owned finance organisations that the US has.

Additionally, many of the private industries in the US are far from free market. The UK's private healthcare industry is arguably more free market than the US's private healthcare industry, although has to compete with the NHS.

This isn't a criticism, just to remark that the US certainly isn't afraid of nationalisation and government owned services.
This is not a story about a war as much as a story about organizations that know better. You can see these cases in various circumstances, from the military to governments to private companies where incompetent decision makers dismiss anything they don't like.

"given the number of people I know who've had a first cigarette and not touched a second"

Okay, now exclude people who did that as children, an experience after which they had zero access to cigarettes. That same survey if demanding an adult experience would be much, much closer.

Everyone has a "Jimmy lit up a smoke and I took a drag and coughed my guts out when I was 9" story.

Overwhelmingly people either had a problem smoking (one that they had to quit through extreme effort), or they never smoked cigarettes at all as adults.

The one "exception" I can recall is a "social" smoker who would tell everyone that she controlled it by only smoking when she drank/at social events, a consequence of which was that she sought drinking opportunities at every venue. She was a problem smoker that turned it into also being a problem drinker.
> Hypothetically in a future where self hosting is non hostile, will you see people self-hosting startups and the like?

Huh, is that not a thing anymore for startups today? In my experience, starting in 2003, across two companies, was that if you need any service fast and on the cheap, you're forced to host it yourself. Run your own mail server, web server, DNS, server housing, all the web apps, etc. and of course spend most of the day developing your actual product. Have the hosted options actually gotten so cheap and reliable these days? Is it a mindset thing?

My gripe with the cloud or SaaS solutions I've used over the years is always that management of them and backup is difficult tending towards impossible and without those you can't rely on these services, it's just voluntary vendor lock-in. When self-hosting, your actually (forced to) learn how they work and be able to fix them. Self-hosting, to me, is the simpler, more reliable option, if you depend on a service for your business and it enables you to get it fixed yourself, when it is not working. It doesn't prevent you to out source the work, if you have the money, but worst case, you still have direct access to your property.

With the hosted options, in my experience, you get all these fancy promises on availability and it being the latest, smartest tech and then the service is down for half a day, your data got restored from days old backups (if at all) and there is nothing you can do except tell your customers that "were sorry and working on it" while you wait for it to come back. :-(
Great Article!

The old AI was focused around this problem

https://en.wikipedia.org/wiki/Boolean_satisfiability_problem

which is a model for your ability to tell if a semantic interpretation makes "sense", such as the "four-horned unicorn".

A lawyer, for instance, thinks that way to interpret a contract, a situation, and possible situations.

Unlike SAT people have the ability to accept something like a "four-horned unicorn" as a special-case entity like Chomsky's "green idea" and those things can live a life of their own.

Basic computer science gives some clarity here: if you look at the way information flows in a system or what storage capacity it has or that it demonstrates experimentally, it is very clear what "deep networks can't do" and Turing would have told you to as well.

A journal could follow a set of statistical standards that could be examined and approved by experts outside of its narrow field.

I don't claim that paper reviews have to be or can be perfect - only that they could be held to a better standard than they are now.

We see plenty of avenues for publishing to a worse standard (self-publishing on an internet aggregator, for example). Let's see some avenues for a better standard.

Why isn't this a science in itself? We could trial some different standards and statistically compare them.

[It was not my claim that scientific papers must be understandable by laypeople, although I think this is an ideal case. If not, it should at least be understandable by people in an adjacent subfield - otherwise, it's just a small group of people talking amongst themselves]

For especially sensitive data, the assurance in this post -- that if you don't see a network request occur on save, your data remains local -- is not sufficient.

Some malicious programs use techniques like delayed network requests to send data when you're not expecting it, and you basically have to audit the entire application to make sure it isn't making these covert requests.

What happens when your autonomous drone decides to shoots neigburs kid for playing hid and seek, in a fashion that drone algorithms find objectionable.

And suppose your drone goes after them, finds them, then what ? You do realize that after, the drive by is done and they "flee" the scene, you can't just go after them and shoot them as a civilian? You can defend your property (someplaces ) but that does not include chasing after them.

Is the drone smart enough not to shoot when there are other people behind it's targets ? what if it's Halloween ?

It's not 1971, but 1973, and we know what happened, the OPEC:

https://en.wikipedia.org/wiki/1973_oil_crisis

Peak oil doesn't mean that there is not more oil, but the point in time where it doesn't make economic sense to extract it, or because demand has fallen or because all the easy oil has been extracted. Some people think that was in 2005.

I have been reading about that concept a little lately and some serious people are saying that the oil companies investment have been fallen and, if that trend don't reverse, we will see a fall in production of 50% by 2025. That sounds pretty incredible to me, but the economic consequences would be very serious.

Referenda are routinely misrepresented in propaganda during debates, and often become proxies for unrelated issues and malcontents (brexit, anyone?). In practice, when you discuss actual issues, pro-Union sentiment is more widespread than reported, and most people agree that "it makes sense" to travel in the direction of closer integration. Even the issues where we kinda "agreed to disagree", like on electric plugs, there is constant moaning as soon as one moves across borders.
You can run a 1500w resistive heater for 50 hours on a 75kwh battery.

I run a 1500w heater in my 30ft RV and it holds comfortable temps down to freezing, in a small vehicle it should have no problem even down to very low temps, 750 watt might be plenty to keep the interior at a safe temp.

For sure most of the work was automatic (the technique for automatically stitching together pictures into a big one has been around for a long time, remember seeing it in Photoshop CS2 (~2005) the first time I think, but probably existed before that too) and then manually touched up to fix anything weird. This is also how taking panorama pictures work on your phone, it takes bunch of photos while you move the camera, then automatically stitch them together based on similarity in the edges (and probably gyro/accelerator data today too).
It's not just about working on various platforms. The whole thing is just ... weird. When you're signing something with eID, you have no idea what you're signing. It could be anything. You have to trust that's signing what you think it's signing. Even the difference between signing and authenticating isn't always clear. It would be super easy to trick a user into signing a document while pretending to present a login form.
I tried to create a ML framework[0] that would work on both CUDA and OpenCL (and natively on the CPU) around 2015/2016, which included creating FFI wrappers for both CUDA and OpenCL. This is where my experience on the subject (and my contempt for NVIDIA) comes from.

Me memory isn't perfect, but IIRC the situation was roughly the following: We were quite short on resources (both devtime and money), which meant that we had to choose our scope wisely. Optimally we would have implemented both CUDA and OpenCL 2.0, but we had to settle for OpenCL 1.2 (which offered reduced performance, but was "good enough" for inference). IIRC OpenCL 2.0 was very very similar in what capabilities it assumed and offered to the CUDA version at the time, and cards like the GTX Titan X had "compute capabilities" that supported features like shared virtual memory between CPU and GPU in CUDA at the time. In fact the advances around memory management (and async copying) that were present in CUDA and not in OpenCL 1.x were the main source for the performance differences between the two.

From everything that I can tell at that point in time, if NVIDIA would have wanted to support OpenCL 2.0 they could have done so based on technical requirements. What the reason for not doing so is, is just pure speculation (lack of internal resources due to focusing on devtools?), but to me it always looked like they were using the edge they got via their proprietary libraries like cuDNN to get a foot into the field of ML and then purposefully neglected OpenCL to prevent any competitors from catching up. Classic Embrace, Extend, Extinguish.

It‘s as distributed & offline as can be.

You could easily print the QR code out and the validator can be offline; the validation still works fine. The validator should have to connect to the network periodically to check for revocations, otherwise everything can be done offline.

Issuance, Revocations & cross country validation requires some kind of backbone but even issuers don‘t have to be centralized if you want. The only thing you need is to get an issuer cert from that central trust authority and you can start issuing passes that are valid.

Currently it still requires a government ID in addition to the pass so it‘s even more „offline“. The specs have room to enable eID solutions though but that will probably be online only as the verifiers will need to be specific for every provider.
For me I feel disappointed that hydrogen fuel cells never took off. Toyota spent a fortune researching them, making them safe to avoid Hindenburg disaster type imagery. But it never really seems to have caught on. You can add a hydrogen pumping station to an existing petrol station too. Plus you don't need to add a charging station to your house. So there are lots of pluses.
