Comment Re:Distortion is fact. (Score 1) 319

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 ;-)

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.

Comment Re:FYI: No ISO download (Score 1) 195

I just keep some windows VMs around. On Win2008 server it failed outright. On W10 it exhausted the disk space after a short while. So I started to look around how big the beast actually is. The HW requirements says - up to 40GB; based on selected features. The offline installer can be forced to download less if you restrict it only one language (who would want a localized IDE??), e.g. with "--lang en-US" - which trims it down to ~19GB ... I think I'll pass for now.

It was here that Omin realized that the job might be challenging, but getting into America could now be impossible. No one at Andela had prepared him for the new reality: "I was just asked to balance a Binary Search Tree by JFK's airport immigration."

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 ...

Comment What about signed code? (Score 2) 143

I occasionally use a signed .jar in the company intranet. Reading TFA, I wondered what hash is used to sign that? It seems that jarsigner is not willing to divulge, so I had to write a little piece of code aaand ... yup, it's SHA1!

How common is this? Is loads of software now susceptible to attack by replacing a original code by a malware with the same SHA1?

How do you expect this "malpractice reform" to work? Isn't malpractice the reason why regulation was created in first place?
