I find it fascinating how people automatically equate "old" with "outdated and obsolete" rather than "tried and true"
Just for comparison: The M16 has been in service in the US army for 57 years now. 57 years before the M16, the US army was still using muskets.
 
@MechMK1 What's the cutoff for when I'm supposed to consider a gun outdated rather than "tried and true"?
 
@nobody When a competing contemporary design shows benefits that outweigh the risks of modifying your entire supply-chain.
For example, switching from trapdoor rifles to the M1 Garand was worth the switch - instead of having a rifle that can fire one shot before reloading, you get to fire 10 shots.
That is a huge improvement, that was worth the change.
Another contributing factor was that "war changed" - the idea of how a war was fought changed between 1900 and 1940 - drastically so.
While WWI was trench warfare, WWII was much more mechanized and much more mobile. And as a result, firearms became more "mobile" as well. Smaller cartridges, larger magazines.
And that's basically where we're at now. Firearms design has plateaued in the recent decades. There aren't any grand changes like from 5-round internal box magazines to 30-round external stick magazines, and from bolt-action to semi-/full-auto.

So, basically, as a lay person, I have no idea what to think when I hear "old"
Also, what's the difference between semi-auto and fully auto?
 
11:05 AM
Semi auto: Pull the trigger once, shoot once.
Full auto: Hold the trigger, keep shooting.
 
11:31 AM
How hard would it be to mod a semi-auto into a full auto?
 
Depends on the rifle. Can range from "sometimes it fires full auto by itself" to "you basically need to replace every component"

Q: In a physical pen test, is there a way to figure out FOV of a tinted dome camera?

user3280964With bullet cameras, this is easy. You look which way they are pointing and then either guess their FOV, or even look them up based on how the model they appear to be. Most dome cameras are behind tinted glass and it's hard to see where they are pointed at. Knowing where a camera is looking is i...

Does any of you have experience with physical pentests?
 
@nobody None. I still replied, using undeserved confidence provided by the Dunning-Kruger effect.

Have a star for your confidence...
 
I'm hoping the question becomes an HNQ so I'll be flooded by rep points.
 
lemme try to verify if this is true, then I'll upvote :)
 
12:23 PM
So, you'll do my homework for me, and you'll give me rep? You're such a nice guy.
 
@A.Hersean Nah, I'll give you rep so that it goes to the HNQ, and then people who actually know something about this come and tell you "idiot, it's not that easy" ;)
See I'm an asshole :)
 
 
1 hour later…

My company sets up camera, access control, and burglar systems, but I don't personally do the design. I would be very interested to see a what a physical pentester could do at some of our customers' buildings.
 
2:06 PM
Why in the world did it not get to the HNQ? :(
 
2:52 PM
Because Mech didn't give it his blessing

is it possible to encrypt a hardrive in such a way that if you enter a second fake key, that it shows fake data, like, not the actual data, but usable other data. such that you can always give the fake key and the attacker thinks it's the real data and your plan to build your deathstar or whatever keeps being hidden
and how is this called?
 
yes
tho i feel like it's... hard to maintain a good fake image?
 
@SAJW It's caused deniable encryption
It's not that easy to maintain in practice though

A: Truly deniable encryption

KrisWebDevDisclaimer: I'm the author of cryptsetup-deluks and grub-crypto-deluks. Deniable encryption is only a part of the solution. There's no perfect solution to protect yourself and your data if you get caught by an adversary. You can hardly avoid the suspicion of encryption, even if the adversary can...
