Good job! OSINT rules. And regarding drones, surely any state actor may be doing this, however doing surveillance by drones over military bases is just so noob. That just points out they don't have a capacity to do reconnaissance with satellites, or they are doing something completely different. Probably making sure the target knows someone is watching, saying "We know where you have your sensitive spots".


They don't need satellites, they can surveil us close up with £200 drones and we don't do anything about it. It's like the story about the astronaut and the pencil.


In Europe we keep 2G as a failsafe, deprecating only 3G.


Not true, see https://en.wikipedia.org/wiki/2G#Phase-out

Many countries/carriers in europe have already shut down 2G, many will shut it down in 2027. A few will keep it a few years more.


A bit of a shame. I had a Nokia 6090 with 8 watt of transmit power on 900Mhz. Combined with a 33 centimeter antenna that phone had reception in nearly all of the European continent. And with a 70Ah 12v battery you had a battery life of weeks. Even with the phone consuming up to 25 watts during calls.

My fancy new 5G smartphone doesn’t work in rural parts of the country. We are going backwards.


It's a hot mess too. When you have an American carrier / phone number on an international plan and they shut down all radios in the case of an emergency in the EU, you still get 2G/3G service abroad while everyone's phones around you is dead.


What do you mean? They are shutting down the radio transceivers for 2G/3G, how would an American number/carrier get a signal in countries that have shut down their 2G/3G networks? Or are you talking about plans to do direct-to-cell satellite service, cause none of those are 2G/3G as far as I can tell?

The whole point is to free up spectrum, how would that work if that spectrum is still in use for the American carriers in countries that shut down the service for domestic use? Why would service be maintained for such a niche usecase?



nope, check the link I posted in another comment: https://onomondo.com/blog/2g-3g-sunset-2/#europe

please note that the list is not fully up to date, eg. in Germany Voda and Telekom have said that they will sunset 2G in summer 2028.


Oh I love the contact page forms, usually this being the only interactive part of a otherwise static website. Either they crash with a visible 500, or they crash in the background, or the mail goes into who-knows-where, as it was set by a guy that left years ago.


PET scan (You have to wait for civic applications of the newly discovered technologies for a while, but the "technology transfer" from CERN to practical applications has a few notable examples.)


PET doesn't use antimatter, at least it doesn't use it directly. It uses regular radioactive tracers.


PET stands for Positron Emission Tomography. The radioactive tracers emit positrons (antimatter), which then annihilate with electrons to produce the gamma rays that are detected. So it does use antimatter, just indirectly through the decay process.


I am familiar with PET. As we both agree, PET does not use antimatter directly, so this article is irrelevant to it (which is what the original comment was asking about).


Indeed, it would be quite difficult to smuggle some antimatter to a tumor. I'm saying that research in this particular area eventually led to practical application, PET scans.


Quite difficult, but also already in experiment: https://home.cern/science/experiments/ace


Don't forget about Tupolev Tu-154. It didn't stop flying as a commercial airplane because of safety, rather because of noise emission limits.


I believe he wasn't even thinking about duplication of applications per person, but the following scenario. Correct me if I'm wrong: Company A would like to hire 1000 qualified IT personnel. An Indian workforce provider has e.g. 10000 qualified people and would be able to get 5000 of them to apply for the visa. From those that win the lottery (e.g. 1 in 3) you would easily cover the demand of the Company A. Economy of scale works here.


Exactly.


That's quite an insult! I wonder how many foreign workers (or foreigners in general) take the eventuality of getting "randomly" detained into account while travelling into USA.


As someone from Europe (the Netherlands), it is an important reason for me to no longer consider to travel to the USA. The idea of the possibility to be deported to a prison facility in South America or Africa, with no due process is simply terrifying.

I would strongly advice any fellow countrymen not to travel to the USA, especially if they are not 'pure' white. There are many Dutch with Dutch parents that are not 'pure' white, because they have a Chinese, an Indonesian, a Caribbean, an Italian, a Spanish, a Moroccan, or a Turkish ancestor (to mention just some possibilities).


>> the eventuality of getting "randomly" detained into account while travelling into USA.

Absolutely every canadian crossing at a land border. The steady number of horror stories is keeping them away.

(Air travel is less impacted as canadian pre-clearance proceedures mean anyone rejected by ICE will not also be detained by them.)


Preclearance only happens at one Canadian airport, AFAIK.


Preclearance is at all the major airports https://www.cbp.gov/travel/preclearance (strange airport name in Ireland)


It's definitely a growing concern, coworkers visiting their home countries have been half-jokingly saying "see you in X weeks, assuming everything goes fine at the border" and even US citizens and permanent residents are being strongly encouraged to plan out contingencies (remote work, what to say to maybe be able to contact the immigration attorney if detained etc) with the company before leaving, just in case.


Anyone even remotely educated takes it into account, although most people have a low estimation of the actual risk


I do. Never been to US since the Patriot act, a have a several-million dollars small startup and would love to see Colorado and California, why not move there, but I’m just afraid of TSA.

On the other hand, I envy USA for enforcing their visas. Europe follows American criminality stats by 10 years, so when we used to mock USA for George Floyd, we’re now in it; for Korean shop owners, we’re now in it; For random knives in busses, we’re in it, and with school shootings, it’s just a matter of time until it happens.

And European people are much farther away from reaching the conclusion that law must be enforced in multicultural nations.


> mock USA for George Floyd

Crime committed by the police.

> Korean shop owners

What's criminal about Korean shops?

> school shootings

Gun control means no more school shootings. See Dunblane.

> law must be enforced in multicultural nations

Nobody ever said it shouldn't, but it has to be enforced in a fair and even-handed way.


> > school shootings

> Gun control means no more school shootings. See Dunblane.

If you are citing Dunblane as an example of gun control not working, perhaps consider the fact that you had to go back to 1996 to find such a bad example in a country with strong controls means that while it doesn't work 100% it does work really rather well. To find a similar example (>20 dead or injured in a school or related environment) in the US you'd to go all the way back into the mists of time to… August. Before that the last large school shooting was Uvale in 2022, still only three years not 29.


> If you are citing Dunblane as an example of gun control not working

No, the opposite. An example of the policy response working. The tragedy was met with universal revulsion and tightening of gun control. There were a few complaints that the tightening was a bit much, but there wasn't a significant faction of people who said that a few dead schoolchildren were a necessary sacrifice for their gun "rights".

(School shootings seem to be a post-cold-war phenomenon. Dunblane was 1996; Columbine was 1999)


> If you are citing Dunblane as an example of gun control not working

I don't see how you read that at all.

https://en.m.wikipedia.org/wiki/Dunblane_massacre

There was a school shooting, and we restricted gun access.

An example of failure of those laws stopping any and all would have been the 2010 Cumbria shootings. But they are still few and far between.


> but it has to be enforced in a fair and even-handed way.

In France, I’ve met a guy who went 180 times in custody between 13 and 18 years old.

I asked him: “Wow. Was it racism?”, literally pointing at his face.

“No”, he said.


[flagged]


That was just something claimed on social media with no evidence to back it up. The autopsies showed he had fentanyl in his bloodstream, but not a lethal dose.


>"This is a fake news claim!"

>"Even if it happened it was non-lethal"

Which one is it? The social media "posts" you're talking about based that claim on that autopsy report.


> that law must be enforced in multicultural nations

per usual it's the other cultures causing the fuss, right.


Criminals get defended against the enforcement of the law, I see.


What I see is someone attributing crime to cultures.


IMO the biggest issue is that instead of reviewing the code of your colleagues, you review some random generated stuff. You know what kind of code you can expect from your colleagues, not anymore. Also you expect that code reviews promote knowledge and consistency amongst the team and helps them to become better in programming. Not anymore either.


"Professor Philip Evans and PhD student Kenny Cheng were experimenting with high-energy plasma to make wood more water-repellent. However, when they applied the technique to the cut ends of wood cells, the surfaces turned extremely black." -> Yes, usually when you burn wood, you get charcoal. Also surface burning of wood is a popular method of wood treatment in the construction industry.

This is such a HN comment. Every single time some new tech is posted, someone here will make a comment assuming that the group of professionals working on it for years have overlooked some incredibly obvious take that they in all their wisdom came up with after a 30s skim of an article about it.


Don’t forget that writing nodejs code qualifies you to have an opinion on anything scientific.


+1 But I’d like to add I think the HN comment is right about 2% of the time


Neither of those generally results in <1% light reflectance however.


Light doesn’t normally cut through solids, doesn’t mean lasers aren’t a useful or unexpected technology.
