You must have some type of distortion when projecting a map of a globe on a flat plane
You can make a non-distorting projection of Earth to a globe. You can also make the globe big enough so that the curvature is virtually indistinguishable from a flat plane in the area that fits in the classroom. Then you just cut off the parts of the globe that are not relevant to the lecture
The command line still after all these years is so utterly broken
a) true, the pressure is 1atm. On how big area? What force does that mean?
b) the scenario that is, in my opinion, dangerous, is a rupture of the capsule that is pressurized to 1atm surrounded by near vacuum. Followed by a collapse of the tube that results from the pieces of the capsule flying in all directions.
However the biggest problem I see from my chair is keeping a relatively fragile tube stretching hundreds of kilometers airtight, undamaged and secure from pissed farmers, drunk idiots, gun fans, vandals and other similar factors.
... but few people with any sense
Unfortunately top officials of USA nor NK do not fall into that category.
Nice explanation. However you are describing a scenario where you have 256- bit key and you have to loop through all possible keys and try to decrypt the ciphertext with it - brute force attack. Yes, in such scenario 256-bits is plenty good enough.
There are other attacks that you do not cover. Such as the key was not selected in random or there is non-brute force attack. Or symmetric cryptography is not sufficient in the given scenario and you need to use public key cryptography where the key has different properties
I occasionally use a signed
How common is this? Is loads of software now susceptible to attack by replacing a original code by a malware with the same SHA1?
If the profession is completely unregulated, and would allow unlimited immigration of medical specialists from anywhere in the world, combined with loosened importation of medications, malpractice reform
How do you expect this "malpractice reform" to work? Isn't malpractice the reason why regulation was created in first place?
