It is allowed to used an encrypted connection to administer a remote repeater, like for amateur satellites. Only the control link may be encrypted. The repeated signals may not, just like any other amateur transmissions.
Radio spectrum is a limited and shared resource. It makes sense that it's licensed and regulated. But compared to other parts of the spectrum, the license is cheap and easy to get and the regulations are minimal. It's a…
How close will this be to being able to resolve starspots on something other than our sun?
That's not hard to imagine. Quick, what's 1/3 of a meter? The sometimes problem with metric is it's base-10. The prime factors of 10 are 2 and 5. Feet are in base-12, which has the prime factors 2 and 3. Three is much…
Probably all of it.
Are the police not able to run away? No, not really. To threaten somebody with deadly force is a felony. You or I would have a duty to run away if possible. A police officer has a duty to apprehend the suspect. What if…
Websites are like salespeople and the police: they can and will use your data against you. The first time I was told about Strava, I immediately dismissed it as useless. (After all, what service could they possibly…

When you don't know what a word means, the best place to start looking is usually a dictionary. For example, Merriam-Webster's definition 3: a small or inferior remnant or offshoot; especially : a group (as a…
Pedagogy? No, this article is written in that modern style of popular non-fiction which is meant to entertain above all other concerns, including such silly things as pedagogy, clarity, rigor, or sometimes even factual…
Or, perhaps planets able to support civilization are relatively rare, and the few civilizations dumb enough to loudly broadcast their presence soon get exterminated when their planets are colonized.
Intentionally or not, the author has cherry-picked the data in a way that completely undermines the article. The conclusion that "lives are at stake" is obviously true and supported by the data, but the implication that…
This is a conversation with Andy Weir about Elon Musk, among other topics.
> O(length of string) per step The big win here is not that it's as fast as the optimal algorithm (it's not), but that it's nearly as fast and vastly simpler. You're technically right that the given code is O(n^2), but…
A MITM can easily spoof IP addresses. You can't trust unsigned data, and IP address headers aren't signed. You also can't trust signed data if you don't trust the signature. That's the real problem here. This whole…

What the article describes is real science. That makes her a scientist. She's also does acupuncture, which makes her a pseudo-scientist. The two aren't mutually exclusive, and here is a person who is both. That's the…
Can you give some examples of problems you've solved?
What if I use a library that forks or spawns threads? It would know nothing about these counters and wouldn't increment them, so I'd never know. That's the neat thing about the original article: you can know if a fork…

Doing anything after committing misses the point. If you can do that, you don't need postgres. For example, suppose you mark an account closed, commit, and then enqueue an event to issue a refund from another system.…
This mapping makes my life much nicer: nnoremap Q @q It turns 'Q' into a sort of enhanced '.' command that can repeat a sequence of multiple commands. To use it, first start recording a macro to the 'q' register. That's…
The last paragraph about eavesdropping is interesting. The agent doesn't actually give out your key, so an attacker can't use your key to decrypt any traffic. Instead, the attacker gets at the decrypted data as it…
I'm sure he's right, but I'm not so sure he actually proved it. The real question is what happens when you deference a null pointer with '->'. He doesn't show us what the spec says on that, meaning there's a gap in his…
