I disagree. I really think doing an intentionally crappy job is acceptable. Not even pretend. I think it is okay to really half-arse it. Or break it. Or be lazy. Or whatever. Excep…

No. Just no. They may do so to the worst of their abilities. Thats their prerogative. The only limit might be publishing something that is actively intended to do harm. But I can't…

GDPR binds an operator of a service. The developer can do as he likes.

Just as you shouldn't eat everything you just picked up from the sidewalk, you shouldn't just use any code thats available out there. check, check and check again...

Security isn't a special license for being nasty. Criticism is fine, even with some urgency due to security being important. But software done for free by volunteers carries no obl…

Defense would actually be quite easy. Just undesirable. There are working antisat weapons in the major powers' arsenals. However, they would produce nasty debris clouds. And then t…

Launch capacity scaling isn't only possible through useless comsats. And astronomy is still an extremely important component for becoming space-faring. No use in going somewhere bl…

Theoretically yes, through interferometry. But that is really difficult when there is relative motion within the constellation such as with starlink.

one gets time signals from photomultipliers, but those are too bulky for traditional pixel sensors. And something as bright as a satellite flare might fry them at an unexpected mom…

Well then, we should also have Elon pay rent for use of space...

Depending on the type of measureme t taken, a dark transient is also harmful. However, by far not as bad as a bright transient.

It will kill astronomy pretty good. The key point is usable observation time. Our current handful of satellite telescopes provide 24h of time a day. Each terrestrial telescope prov…

Modern astronomy works at the edges of whats possible, a single frame might take hours. Needing multiple frames would mean multiple days per observation. It would mean no longer se…

Yes, but stability against vibration and thermally induced warping is also important. So you could make the mirror thinner than on the ground, but not really thin.

Cherenkov telescopes for neutrinos do look down for reasons of schielding. Neutrinos can pass the earth, other particles not so much. But those are a special case, air cherenkov te…

Gravity is an issue for mirror production. But it is far less of an issue than tension and deformation during the months- to years-long cooling of the substrate. The temperature an…

Because cherenkov radiation is only observable in a transparent medium like air or water. Space doesn't work because the speed of light in space equals the speed of light in vacuum…

There is CSS media query for exactly your use-case. No need for sniffing, round-trips or any server-side activity at all.

Sites need to be told to obey DNT with a legal sledgehammer. Still hoping...

Exactly. That is also why "logging in to Chrome" or rather Google is such an insidious misfeature. Soon they will be the only ones with cross-site tracking and third-party-cookie e…

Agreed, for things like autoplay. But dual-use features like feature detection that also enables fingerprinting cannot be replaced by randomized misinformation because that would r…

Also, "please upgrade, then call back" is always the first point on any support call checklist.

Yes, but unfortunately using the user agent for only non-stupid reasons is a postcondition for the hell freezing over.

That would still cause pages to do evil things if users set their privacy budget to "0/paranoid" or anything below "11/just gimme all". Just as with adblockers users will be nagged…

Client hints are not any more useful than traditional UA for privacy or progressive enhancement. Its the same content, just split up. Any browser not sending everything will have a…
