Sorry I have to rectify you here. Diodes can be used as switches. In particular in the RF world you can find PIN diodes. When you add a DC signal it will pass the RF through. Without it, the RF signal is too small to make the diode conduct.

I agree with you. There is a new wave of radio amateurs. And I think it is a good thing that there are both experimenters and people who see it more as a utility. There is enough spectrum for both to co-exist, and it is better for the hobby. Experimenters alone will never fill up the airwaves. Without them, the technical expertise and hacker mentality is lost. I actually think that there is a very bright future for ham radio. If there is something that needs to change, it is the legislation that is too restrictive and not adapted to the things that are possible with modern technology. I'm thinking about remote and robotic operations, for example. Or maybe encryption should be allowed to facilitate configuring remote repeaters and other equipment. I think the current legislation had a ham station in mind that was fine at the time, but it restricts current experimentation unnecessarily. Maybe I'm wrong, but that is my feeling.

I don't like the name "dependents". Maybe "slave" could be replaced by the gig-economy equivalent "freelancers"? It has "free" in its name, so that's doubleplusgood.

Sure, but if your decisions endanger my safety, we need to talk. I cannot simply say it's my decision to empty a bottle of liquor and go for a drive either.

The problem is that the more effective our responses to the pandemic are, the more useless they will seem. We can clearly see that the measures we have taken are effective. The curve has been bent and we have all made sacrifices for this to happen. Now we all start yearning for life to return to normal but this will not happen anytime soon; the virus is still here. The only thing we can do now is to slowly relax the measures as the virus becomes more visible due to increased testing capacity, and hope there will be a vaccine soon. It's difficult times, half my coworkers are unemployed now. No idea how much longer I'll be able to keep mine. But we'll make it in the end. I live in a country where social welfare is well-organized, so I don't need to worry *that* much. Still, it's tough.

Just an educated guess, maybe they sued him for bad bookkeeping?

It's the small toe, right?

Is dark matter an accepted theory? As far as I know, only the observations regarding unexplained gravitational effects are accepted, the rest is still up for grabs. Dark matter is just a placeholder name for something we still need to figure out. There are some reasons why subatomic particles currently are the prime candidate, but that doesn't mean that other explanations are excluded.

You seem to have some really infantile perception of how science works...

Seriously? You really think this is no longer investigated because "they have solved it"?

I just got an Acer Aspire V15 Nitro and one of the things I like about it, is that it runs quite cool even after compiling software for half an hour. Then again, that doesn't require the NVIDIA card to do anything, and I don't know how that would affect the temperature. As I just got it, my experience with it is limited, but I like it so far. It's a very fast machine.

This article is basically saying that research and innovation are bad. That's fucked up if you ask me.

or as a byproduct of fission, that's the source of most Helium on Earth (alpha particles are Helium nuclei).

It's smart, but emotionally unstable.

Ditch Minecraft and make Minecraft 2. Better graphics! Faster! (Runs on windows only).

Instead of a spectrum analyzer, you can use an RTL-SDR dongle as described here. Sure it has a lot of limitations, but it only costs you 10$, and with the scanner software you can get a very wide bandwidth.
