> I'm running a browser in a VM... What malware?

Your faith in the security of VM sandboxes is misplaced.

It is trivial to write a program which can detect if it is in a VM. And then, attack the hypervisor and escape the protected environment. As virtualization has become more common, such malware has gone from academic exercises to real-world exploits.


My favorite line:

Finally, the most interesting attack that malicious code can perform against a virtual machine emulator is to escape from its protected environment.

Saying that radio images translated so we can view them in at a freqency visible to us are not "real" is like saying images produced using night vision goggles are not real.

The waves involved in this issue are not part of the observable spectrum for humans. Converting them to visible frequencies for our observation does not make them any less "real" except to the pedantic or to those of us who go as far as to say that observable science can't prove anything.

> Why not image the center of a galaxy that's plane is perpendicular to us?

Another factor: on that video I linked, the scale on those images is 10 light days. I don't think modern astronomy can resolve individual stars on that fine a scale, which would be required to produce the same effect while viewing another galaxy.

That's another thing that makes that image amazing to me... how close those stars are. 10 light days is nothing, cosmically speaking.

> There's roughly 25,000 light years of dust and stars to see through.

You're right... it would be impossible to view those stars using the optical spectrum. However, the scientists in this case, and for the multi-year time-lapse loop I linked to used radio waves which were unaffected by dust. One might think that interposing stars would block out the view (after all, the view is sideways through the "platter" of the galaxy) but given the far separation of the stars, the view is not blocked even at such vast distances.

I initially shared your incredulity, and I did the research, and that is indeed a radio image of the actual stars at the center of our galaxy.

> the EHT team is ultimately after to prove the existence of black holes."

It's already been proven. There is a black hole at the center of the Milky Way galaxy, and it's been named "Sagitarius A"

Using infrared telesopes, you can "see" stars orbiting the black hole at the center of the galaxy. Orbits of about 28 stars have been observed and using math, the mass of the stars and the required mass of the black hole has been calculated. Only a black hole can account for the kinds of orbits you see those stars doing.

It is a sight to behold and at first I could not believe it. Watching the stars at the frickin center of the galaxy orbit a black hole is a stunning sight once you truly grok what you are seeing.


Realize that this video is not an artist's intepretation, but is actual imagery of stars orbiting something of immense mass, something which can only be a black hole.

Most grand juries are lapdogs of the prosecutor, it is true. When they go off on their own, they are called "runaway grand jurys" and courts and prosecutors don't want them to know it is possible. Much like jury nullification... no court will instruct a jury that they can nullify, similarly, no court is going to tell a grand jury they can subpoena on their own without the prosecutor saying OK.

But it is rare for a grand jury to go off on their own these days. This was not always the case. Historically, grand juries were independent of the prosecutors. But these days, it is a rare thing, and the Ferguson grand jury probably played the lap dog.

I've worked as an election judge in Colorado and in Pennsylvania and in both states I got paid between $100 and $150 a day for election day, and got paid for the training. It's not a bad way to spend a vacation day. Get paid for the vacation day, and the hundred and some bucks from the county, and get that vibe you get being a part of the democratic process. Plus, for places with electronic voting machines, it's good to have a technically oriented person there, because it is, after all, a computer and setting them up is usually not easy for non-techies.
