As has been established in other threads here, the metal button thing the prongs slide onto is an earth connection.

Just take an apple charger and a multimeter, try to find a path to ground from the computer side, I'll wait. Plugs have regulations on how they can be built which are different from how they must be connected.

>There was the person with the relative in Los Angeles who was worried about going to London

This amused me because living in LA/California, I get the same style unhinged comments completely disconnected from the reality of what is happening here. We certainly have our share of problems, but you'd think we're Somalia the way certain people talk. I had a friend from Arkansas visit last summer and it definitely reset his world view a bit.

I assume this is all just deflection. It is more politically convenient to talk about bad roads or the homeless problem in California, than to address that your state's schools are in the bottom 20% of the nation.


The problem is that juniors given access to AI don't seem to learn as much. AI just gives them fish over and over instead of learning how to fish.

i see this first-hand; they don't even know what they don't know so they circle over and over with ai leading them down rabbit holes and code that breaks in weird ways they cant even guess how to fix... stuff that if you were a real programmer you would have wrote in a few minutes let alone hours or days...

Yea, giving people a blank Claude with no setup will get you that.

What you could do is encourage (or force with IT's assistance) them to use a prompt (or hook or whatever) that refuses to do work for them, but instead telling them where to change and what without actually doing the work.


Bunch of napkin math: you'd need something like 10 kilowatts and 140 km/s detla-v to catch up to Voyager in a decade, assuming a New Horizons equivalent Earth escape velocity. The amount of xenon is technically possible, however even assuming impressive 8000 Isp thrusters, your fuel mass fraction ends up being 90+% fuel which doesn't leave a lot of mass for that reactor and radiators.

A 20 year intercept would be pretty reasonable though. It needs about 15 km/s delta v after that NH style escape, about a kilowatt of power, and maybe a 25% fuel mass fraction at 6000 Isp. That's all very reasonable by current standards.


I understand that celestial mechanics are involved, because "stuff in space do not fly on straight lines", but why is the delta V budget 10x smaller for 2x more time? That feels counterintuitive :/


Is that including a Jupiter/Saturn assist?


No, that's more than napkin math but I feel the numbers stand for themselves that we can't really do better than decades. A few km/s won't change that.


The dearth of case law here still makes a negative outcome for FSF pretty dangerous, even if they don't appeal it and set precedent in higher courts. It might not be binding but every subsequent case will be able to site it, potentially even in other common law countries that lack case law on the topic.

And then there is the chilling effect. If FSF can't enforce their license, who is going to sue to overturn the precedent? Large companies, publishers, and governments have mostly all done deals with the devil now. Joe Blow random developer is going to get a strip mall lawyer and overturn this? Seems unlikely


The restrictions on GPS prevent ballistic missiles, not MANPADs. Typical limits are 515 m/s and 18,000 meters (try using your phone's GPS on a commercial flight, it works fine near a window). Update rate is probably the biggest issue with GPS and MANPADs.


Are these chips so much better at calculating GPS position than general purpose CPUs or consumer FPGAs? Feels like a silly restrictions for anyone capable of building a ballistic missile. On the other hand it seems relatively computationally expensive to do a speed check every time for low energy devices.


The headline is a bit sensational considering all we know from the reporting is that he isn't working there anymore. Fired likely, sure, but not for a fact.


My phone can regularly pick these up with a clear western view in Los Angeles. They're relatively low in the sky so they don't serve their intended purpose here, but I'm not complaining about having more satellites to lock on to.


Western view?

Large fleet operators tend to self insure rather than having traditional auto insurance for what it's worth.

If you have a large fleet, say getting in 5-10 accidents a year, you can't buy a policy that's going to consistently pay out more than the premium, at least not one that the insurance company will be willing to renew. So economically it makes sense to set that money aside and pay out directly, perhaps covering disastrous losses with some kind of policy.


It sounds like they want flexibility for immigrants who may feel the need to keep a low profile, despite their legal status.
