can amateurs bounce photons off the mirrors left there by Apollo 17 yet

or does it still need industrial grade lasers?


Getting industrial grade lasers is the easy part.. it seems to be within range of aliexpress available tattoo removal laser (based on the laser pulse energies listed in https://en.wikipedia.org/wiki/Lunar_Laser_Ranging_experiment... and rough laser tattoo removal energies listed in https://pmc.ncbi.nlm.nih.gov/articles/PMC10421900/ .. take aliexpress rating with grain of salt)

You do need access to a large telescope (at least 1.2m based on the wiki article), a sensitive detector (is photomultiplier tube sensitive enough??) and most importantly, access to your local laser clearinghouse so you don't accidentally shoot an airplane, blind the pilot and got arrested, or a satellite and start a war (if you believe some guy on quora). Probably the last part is the hardest thing for an amateur


There is a very simple alternative to age verification

WHO IS PROVIDING INTERNET TO A CHILD

they are liable

there's no such thing as free open access internet without someone paying the bill

unless it can be demonstrated the child stole internet somehow, hacking, etc.

then the person providing the internet is liable for the child's activity

Same if you aren't going to supervise your child and they come home for hours after school and watch porn on the TV

They don't age verify to get cable TV

If you have a credit card, you are an adult

Someone is paying the bill, they are the adult, they are responsible


What a nice vanilla view of the world. It's way to simple as an answer and lacking links to reality.

If not before but with high school kids will need access to a computer and also the internet in many schools and countries.

I get that parents are responsible but parents have limited resources. Even the best parenthood will not keep kids from wanting to engage with peers. Even the best filter or block by parents will not cover the www and their millions of websites and services.


What if the parent is not responsible?

Should society help the child, by making it more difficult for them to access harmful material, in the same way we age verify alcohol?

What if the parent is responsible, but finds themselves in a situation where they don't have the time/ability to either educate or set up robust controls? Should we make their responsibilities easier?


Instead of controlling the children, we should control the source. Perhaps we should ban harmful content from the internet. Not the government. But we, as users, need content to be reviewed by moderators. People should decide what is harmful. I’m sure we all know what is harmful, not just for children. Psychology shows us what goes on in an adult’s brain, it is exactly the same as what goes on in a child’s brain.

With this line of reasoning you can just take away any agency from individuals and put it into the hands of the state, which leads to totalitarianism.

Public policy seems tricky if we must take every line of reasoning to its extreme.

The idea that the state should decide which way of parenting is responsible is extreme.

Before Youtube and Wikipedia there used to be a great website I liked to read about Philo Farnsworth but cannot remember the name of it for the life of me now

farnovision.com ?

if you haven't seen the footage from someone in a passenger jet nearby, it rocks

Think about how much technology evolved to create that scene, to fly nearby and being used to take that video, wow


You can't really see anything in that video. The craft is very small on screen.

I suppose zoom would have some awe factor

But it's awesome enough as is

a 100 meter tall spaceship nearly 6 million pounds carrying nearly a million gallons of fuel for nearly 10 million pounds of thrust for JUST eight minutes

all that to escape Earth's mighty gravity well

pretty freaking amazing to watch even at that distance


Didn't Nokia put a 4G cell node up there?

Who is going to be the first to make a smartphone call from the moon?

Lag won't be too bad, just 1.5 seconds or less


2.2-2.7 seconds of delay due to light speed alone (so maybe a few ms more for electronics and en/decoding).

I had to watch "go at throttle up" on replay on the news in 1986 for the entire year, like almost every newscast

I was only a teenager and it burned into my brain badly

To this day cannot watch any launch with people onboard live


The event itself was a few years before my time, but after reading about it and eventually watching the historical news footage, the phrase "go at throttle up" also seared itself into my brain, and ever since I flinch when I hear it.

Same. I watched last night, UK time, and I couldn't shake the worrying feeling. I was relieved that they got into orbit. Now I can be a little bit excited until re-entry. That worries me for the same reason.

In the UK as a kid, when Challenger happened, our children's news programme reported it before the mainstream TV.

So what happens in a few years when a submarine pulls up some miles off US coast and unleashes 100 super-automated drones to terrorize the country?

Heck maybe not even a sub needed, some smaller country could have an automated tiny raft too small to be seen on radar tow in the drones

They could charge via phantom power from powerlines and will find a way around GPS jamming


I think you could just ship generic robot dogs in a container and have local contractors straw-purchase firearms, 3d-print cradles, and combine them. None of the contractors would need to know what they were doing.

wondering if there's a startup opportunity for lab testing peptide batches somehow

doubt current supplement labs would be up to the task of certifying things injectable

very risky to bypass gut digestion safety in the human body with unknowns


It already exists. There's no reason anyone would know if they never ventured into the backwaters of PEDs for sport, but third-party labs are out there which will send you back a full analysis of any sample you send it, and reputable sellers anyone bothers to actually buy from will reimburse the testing expense provided you publish the results on any number of web forums that exist for the purpose of vetting these sellers on quality and purity of their products. It's nothing like buying heroin from the street or at least it hasn't been since 20 years ago.

Also US MedSpas and other boutique pseudo not-quite-medical clinics will already inject you with just about any peptide other than insulin as well as NAD+ if you feel you need it for some reason. You don't, but they'll still do it.


I would expect whomever does the certification for insulin and GLP's would be up for it. existing peptides on the market not counting all the peptides people eat daily in foods

same

     T-Mobile USA, AS21928 does NOT implement BGP safely

Sean Duffy:

"do not let safety be the enemy of progress"

aka some of you may die but I'm okay with that and will sleep fine
