Get a toy one

At 7, it will be great

Get preferabily one with >= 50x mag, so you can see cells, etc

Later you can think of a better one

I really don't remember how old I was when I got my first (toy) one, but it was a built-it-yourself kit

Then I got one that was 100x-300x-600x (which was 'more real') and it was lots of fun

The real "broken stuff" is probably in : DirectX

Or better, the lack of a precise specification. And different manufacturers implementing different details in different ways.

But it's lots of games depending on several different functionalities. You can certainly test in most games. But then you find out Quake III relies on an old bug or quirk of the spec that you fixed and that broke the game

Game developer makes the game with available cards. Sees that no one does 'item X' correctly, finds a solution that works on everybody. Item X is fixed but breaks old games.

Not to mention AMD (ATI) has a "tradition" of shipping crappy drivers.

True, it's field electron emission!

The interesting parts are the very small size and the addition of the gate which allows modulation of the electron flow.

Absolutely. I would describe it more as a "new type of transistor" than a "small vacuum tube" (and the fact that it's solid state and apparently can be integrated with other devices)

The article is painful in some aspects

Electrons move more slowly in a solid than in a vacuum, which means transistors are generally slower than vacuum tubes; as a result, computing isn't as quick as it could be.

I'm flabbergasted.

Meyyappan, who co-developed the "nano vacuum tube," says it is created by etching a tiny cavity in phosphorous-doped silicon. The cavity is bordered by three electrodes: a source, a gate, and a drain. The source and drain are separated by just 150 nanometers, while the gate sits on top. Electrons are emitted from the source thanks to a voltage applied across it and the drain, while the gate controls the electron flow across the cavity

This is really a vacuum tube if you add a high dose of immagination. Really

The separation of the source and drain is so small that the electrons stand very little chance of colliding with atoms in the air

Makes me wonder if tunneling plays a part here

Makes sense if you want to reuse the disk and don't want to use a computer to rewrite it.

I think the overcurrent is not just "to the chip" but may be exactly tied to the erasing process, so you just "fry" (over erase) the memory cells

And that's exactly the point, if you're in a critical situation (like at gunpoint) you don't want to waste time with "overwriting" but should just go to the overcurrent method.

"First method goes through the disk, overwriting all data with garbage"

That's the WORSE possible way to "self destruct"

Do you know why in flash memory they have to work differently then on a spinning disk?

Erasing blocks takes a lot of time. Exactly because it's erasing a whole block!

Erasing and then overriding seems pointless (even though theoretically you could dissolve the chip in acid and then measure the charges there to see if you can recover traces of data)

The second way seems much more promising.

And by the way, "InVincible"?! Really? It should be the opposite of that!

Do you know what makes sense?

Not wasting time doing graphical gimmicks for a window manager (which will be buggy and slow anyway)

"to help the perhaps 1-2% of your userbase"

I think the number is higher, still, why should I upgrade my machine to run the latest versions?

Yes, because the only observations that are true is what comes from a lab, right?

Vaccines come from the exact kind of observation the parent mentions, sure it was tested.
But of course, modern "web scientists" only consider "research" that comes from lab financed companies

But if you want to test it, sure, go ahead, because obviously you know better than several years of immune system research
