Why didn't you recommend signal?

How could you possibly verify what code they are running server-side? Typically, the way it goes is that you implement e2ee such that even a fully compromised server cannot read the clients messages, publish the client's source code, a

You can simply join those channels. Getting an invite is not hard, or even unnecessary, from what I hear.

My ex had an erdos-bacon number of six or seven when she was in grad school. One paper with your thesis advisor and having one role as an extra gets you there quickly.

Is there something like Cypher that can be leveraged to make the queries against a postgres graph a bit more digestible?

Ah, that makes sense. I actually didn't know that about openbsd.

Well, tcpdump is explicitely not what you want to do in this case as Moxie points out, but other than that i guess, yes, it's similar.

I mean you can still use 53/udp, but the point is he doesn't start a service or sniff the interface with libpcap, because both of these increase the attack surface.

Pretty cool. Have you seen considerations regarding port knocking by Moxie Marlinspike? I think he raises some valid points: https://github.com/moxie0/knockknock Instead of using UDP he reads the firewall log. Also he

Because the problem lies somewhere else which is not extremely basic. Relativistic effects are not the issue here.

You're not a cosmologist, are you? I'm not anymore either, but when I was in grad school, everyone agreed that LCDM is probably wrong. Most researchers pretty much wanted it to be wrong. All they did was try something different (q

No, it implies it expanded in the meantime. We can see that it was a hot plasma up until 300k years after the big bang. This isn't some redshifted illusion, the matter was literally packed so densely and thus so hot that it was in anot

How would you explain the CMB? We can literally see that the universe used to be much denser.

She's following a hunch, it's what scientists do. In this case the hunch is that the model is not wrong. That's a far cry from saying it's impossible to be wrong.
706.
by mr_mitm 2y ago
Rest assured, this has been taken into account. The scientists who spend their life working on this topic have had the same thoughts you had within minutes of learning about the problem. It's extremely basic stuff actually.

> Whenever a scientist says that it's not possible that the model is wrong, then I just roll my eyes. But no one said that. Im fact, scientists are known to say things like: all models are wrong, but some are useful.

Plus, as if tensor fields on Lorentz manifolds weren't already complicated enough, physicists aren't happy until they can write down some differential equations. So not only are you doing calculus, you're doing it on curved m
709.
by mr_mitm 2y ago
Yes, very simple, except that when physicists say "tensor", they mean tensor fields, on smooth, curved manifolds, in at least four dimensions, often with a Lorentz metric. Things stop being simple quickly.

Writing numerical solvers isn't that inspiring by itself to be honest. But I agree that the subject is fascinating. I suppose the code is not public so we could see ourselves, is it?

They always let anyone publish a paper, as long as the submitter has an email address from a known institution OR an endorsement from someone who does. Any edu-email may actually suffice if I'm not mistaken.

Sorry for coming off as snotty. It wasn't my intention, I thought my statements were rather matter of fact. It's possible that after having attended two lectures on differential geometry I have forgotten that some of these things

Pi doesn't vary. The ratio of circumference to diameter of a circle may vary depending on the geometry. Clearly everyone means euclidean space unless specified otherwise. Any other interpretation will only lead to problems, which is wh
714.
by mr_mitm 2y ago
In non-euclidean spaces, your definition of pi wouldn't even be a value. It's not well defined because the ratio of circumference to diameter of a circle is dependent on the size of the circle and the curvature inside the circle.

Even forces are a model. Interestingly, this is accepted with much less skepticism, probably because we learn this at a younger age.

They are for software updates, but this was just an update of the definitions file, which couldn't be parsed properly by the kernel module. These are rolled out immediately to provide best protection against the latest threats. As I un

First you need to know they had possession. If they don't want you to know, how else could you tell if not for a tamper-evident seal?

In the most extreme case, the evil maid replaces your laptop with an exact replica that does nothing more than somehow bridge USB devices via radio to the original to take care of keyboard input and the smart card. Sounds like paranoid scif

What's different with these scanners? Can they identify the molecular structure of the liquids or what was the problem previously?

by mr_mitm 2y ago
You cannot trust the BIOS after an evil maid attack. And there can be sniffers on the physical layer inside the laptop.
