Sure. SNI (and the certs) is additional detail if it's not hidden. From good causes (like reverse engineering) and less good causes. I was however mostly thinking about IP addresses, which transport layer cryptography for obvious reasons can't help against disclosing to an observer on the network.
 

This principle still holds. It's just older versions and older ciphers being recommended against. Not transport-level security with a SSL / TLS-like approach.

Then, of course, additional security is also needed in many cases. Any TLS scheme allow a man in the middle to see who you are talking to, if you are not using Tor (and that protocol also has some traffic analysis risks). And you may leak the hostnames you are looking for, either to you DNS server provider and anyone listening to the net in between, or to your DNS-over-HTTPS provider.

I would be more impressed by some TV or similar device that could display different content to different viewers - from the *full* screen.

Probably by having each part of the screen sending different light signals for multiple directions. Kind of like how a lighthouse project white in some directions, red or green in others. But dynamically controlled, with several LED:s per pixel, and some quite advanced optics. With narrow enough beams, this could perhaps even be used for glassless 3D.

Ideally with some software that could track the location of each viewer and calculate which sub-pixels need to transmit to reach them, even if viewers changed position. Without said tracking sensors used for any other purpose - no analyzing, no ad tracking, no DRM ...

I wonder which part is most wishful thinking - the technology or that Samsung could skip abusing it for privacy violations?

"AI-enabled threat ransomware and crytpo-mining malware detection technology" has to live somewhere - could it be in the Manegement Engine like similar features? I am quite a bit skeptical for two major reasons:

1. Anti-virus and threat detection software - what is really an appropriate to run in this environment? Could we get more prevention (like fixing your side channel attack-enabling bugs ...) instead of detection? I would rather stop exploits from executing at all, instead of detecting their presence on a system.

2. I would rather have all parts of the CPU and chipset accessible and configurable by the owner of the system. Having this separate and inaccessible helper CPU with full access to your system - and seemingly giving it even more tasks - is both principally wrong, anti-consumer, anti-right to repair and possibly a black box full of even more attack vectors than already discovered in the ME.

Yes, I don't believe solar electricity is "free". You need equipment and space.
It's just that fusion most probably won't be either.

Citation needed.

Yes, it's got advantages over fission, including waste management. But "basically unlimited energy"? (or perhaps "too cheap to meter")?
Yes, the fuel is more abundant than fission fuels if we can extract and use deuterium from the oceans. But we are still limited by the cost to do that, and the capital and running costs of the plants (which, given the requirement to keep a 100-million-Kelvin temperature process in place will require some high tech). Fusion (at least for the moment) also will need the usual thermal power plant equipment like turbines and cooling.

You could argue that solar - from our terrestrial point of view - is a better fit for "basically unlimited energy". We get it beamed for free (how much and when varies, of course), and you need no moving parts to convert it to electricity.

One more argument for make user contributed data available and under an open license, if you can get it working (as a non-profit or business). Goodreads may be a nice site, but you get reliant on the whims of a third party - even if the data is created by users.

If the non-profits running Open Streetmap or Wikipedia would behave ill enough[*], both the database and software is available, licenses for reuse and most probably mirrored by other people. This way the project could be forked - as have been the case for software - for example XFree86 / Xorg and Cyanogenmod / Lineage OS.

Possibly even the threat of forking helps to curb things like closing access to all APIs.

The European high speed rail network is now quite extensive, with a network allowing 200 - 320 km/h operations - https://en.wikipedia.org/wiki/....

The night step for night travel? Perhaps using this network with a high speed sleeper train. With such a train, you could go between more or less all parts of central Europe by sleeping. Not a Star Trek transporter, but a bit closer :-)

The railways of China actually have some high speed trains like that:

Yes, cheap airlines did a lot of damage. Often airlines operating (at least in Sweden, for example Ryan Air) from municipality-subsidized airports ...
The train do not need to be completely expensive, however. I remember being able to find tickets Stockholm - Amsterdam for 59€, including a berth in a quite comfortable couchette car. That's less than even some hostels just for the sleeping space.

Also, I know some sleepy-head business travelers preferring the night train: If you have to be at a conference at 9:00 in some city, you have to take a brutally early morning plane, if possible at all. Or take an evening flight + hotel. Compared to the latter, an overnight train - even in a comfy sleeping car with shower - can be more economical. And it will allow you to leave your home later.

I play in the Uppsala University Symphony in Sweden. We go on tour all over Europe, and many of us prefer going by train. Many do it for climate reasons, to see more or the places we visit, or the convenience of getting straight to the city centre.

But the train also have extra advantages when traveling with instruments: If you have seen (which a colleague did) a cello being smashed to pieces by airport crew (despite promises of special care), you don't want to check it in. And putting it in the cabin is hard - you need to pay for an extra seat, if allowed at all. Double basses are completely out of question. Even violins and french horns have problem fitting in the overhead rack - and the few that can fit their instrument, have used all their hand luggage allowance.

On the train, you can bring every instrument (except timpani ...) on board, and keep it close to yourself all the time. On the night train, we booked an extra bed (for 10€) for some larger instruments to share, but you can have them standing on the floor too, in your locked compartment. The overhead racks are also much more generous on the train; no problem fitting a bassoon or bass clarinet for example.

And no security theatre, no waiting in lines for boarding, no putting your luggage on the scales and hope for the best: Just go to the train on the station, show the ticket when boarding (on night trains) or during the journey (on day trains). Bring as much or as little luggage as you need - all nearby during the journey.

That's hard to find - normally toilets are connected to storage tanks now, flushed by a vacuum system. At least in western Europe; I only found open-flush toilets on some of the less-luxury (but still quite clean and comfortable) domestic night trains in Russia when traveling from Japan to Sweden some years ago.

Yes! Typo.

Perhaps you could argue that there are European countries in South America too (a bit of France that hosts the rocket launch facilities, Falkland Islands, ...) but that was not my intention :-)

There are actually some sizable deposits in the Czech Republic. Otherwise, Australia and some South American countries in South America are large producers.

But yes, always keep mining at a minimum. Sharing cars instead of owning a personal motor vehicle (quite feasible in European cities), not getting a larger battery than needed and using electric bicycles (which require around 1% the amount of battery metals compared to a car) instead is good not only for metal housekeeping, but frequently also for other global and local environmental qualities.

When some lithium is in circulation and batteries finally wear out, recycling could and should be a source to avoid mining. Rönnskärsverken, a smelter and metal processing complex just some km from the planned Northvolt factory in Skellefteå (my family's old town) is AFAIK currently trying out methods for this.

Yes, the airline industry is not the largest single source of CO2 emissions. However:

1. The same is true for most everything, if we break it down enough. SUV:s? Some percent. Poultry industry? Not much, compared to the global total. Emissions from Belgium? Just some percent, no need to change anything in Belgium. This attitude however, will not make the change needed at all. Also, people tend to use it like "hey, look at someone elses emissions". That won't cut it.

2. The climate impact is larger than one percent - perhaps up to 2 or 3%. One reason is that emissions at typical flight levels for passenger jets have a larger athmosperical impact than ground level emissions. See for example https://mpimet.mpg.de/fileadmi... or the overview on https://en.wikipedia.org/wiki/....

3. The only reason this is just 2-3 percent is because globally only very few people fly (as in the article). If everyone would get the same level of air travel consumption as affluent western countries, this would be far larger.

I wonder if the 5G protesters would get angry about this.
They usually complain about the high frequency of "5G radiation" - and well, visible light is around 100 000 times higher in frequency (and energy per photon).
