Encrypted DNS, widely known as DNS over HTTPS, protects DNS traffic by encrypting it.

Ya don't say.

The missile knows where it is at all times. It knows this because it knows where it isn't. By subtracting where it is from where it isn't, or where it isn't from where it is (whichever is greater), it obtains a difference, or deviation. The guidance subsystem uses deviations to generate corrective commands to drive the missile from a position where it is to a position where it isn't, and arriving at a position where it wasn't, it now is. Consequently, the position where it is, is now the position that it wasn't, and it follows that the position that it was, is now the position that it isn't.

In the event that the position that it is in is not the position that it wasn't, the system has acquired a variation, the variation being the difference between where the missile is, and where it wasn't. If variation is considered to be a significant factor, it too may be corrected by the GEA. However, the missile must also know where it was.

The missile guidance computer scenario works as follows. Because a variation has modified some of the information the missile has obtained, it is not sure just where it is. However, it is sure where it isn't, within reason, and it knows where it was. It now subtracts where it should be from where it wasn't, or vice-versa, and by differentiating this from the algebraic sum of where it shouldn't be, and where it was, it is able to obtain the deviation and its variation, which is called error.

The missile maintains constant awareness of its location. This is achieved through its intrinsic understanding of where it is not. By calculating the difference between its current position and where it isn't, either by subtracting its current location from where it isn't or vice versa, the missile computes a deviation. This deviation is then utilized by the guidance subsystem, which is programmed to issue corrective commands. These commands are designed to reposition the missile from its current location to a desired one. As the missile reaches a location where it previously wasn't, it updates its current position. This means that the missile's present location is now where it used to be absent. Consequently, the position that the missile occupied before is now a location where it is not.

In situations where the missile finds itself in a position other than where it intended to be, the system identifies a discrepancy. This discrepancy is quantified as the difference between the missile's current and intended positions. When this variation is significant, it can be adjusted by the Guidance Electronic Assembly (GEA). However, for the GEA to make effective corrections, the missile must have knowledge of its previous position. This historical data assists in accurate recalibration, ensuring the missile's course remains true to its intended trajectory.

The missile guidance computer operates on a complex principle. When a variation alters the information regarding the missile's position, uncertainty arises about its exact location. However, the system is fairly certain about where it is not and remembers where it was. It computes its current position by subtracting where it should be from where it was not, or the other way around. This calculation is refined by contrasting it with a composite of where it should not be and where it was. Through this process, the missile identifies both the deviation from its intended path and the extent of this deviation, known as the error. This error calculation is critical for realigning the missile's trajectory toward its intended target, ensuring high precision in navigation and impact.

Those certainly are words.

Catch-22 or Gravity's Rainbow, if my memory of books I've read once is still accurate.

Neither, its a copypasta born from a usaf pdf. I think it might actually be the og version, vintage af.

"Mullvad's encrypted DNS solution is available free of charge for everyone. The company advises customers of its DNS service, which is available for a flat-fee of 5 EUR per month, not to use the encrypted DNS service as the DNS resolver of the VPN server is handling this automatically. The performance of connections could be slower, if users make the switch."

This nonsense was written either by an AI or a drunk.

i like that they have a public repo with the details on how their blocklists are compiled and what's in them.

[–] hoshikarakitaridia@sh.itjust.works 2 points 10 months ago* (last edited 10 months ago) (1 children)

What does that even mean lol

Just FYI there's a standard monthly fee for use of mullvad. This will probably be a feature expansion and will run under that same fee.

Which means this whole paragraph is utter garbage.

Edit: my bad, I stand corrected.

"anyone can use mullvad public dns for free. their paid vpn service already uses it so don't set it up separately if you're a subscriber"

[–] Aggy@kbin.social 2 points 10 months ago

Thank you for translating. I use their service and am happy I don't need to make any changes.

[–] bandwidthcrisis@lemmy.world 1 points 10 months ago* (last edited 10 months ago)

Maybe the second "DNS" should be "VPN":

The DNS is free. They advise users of their paid VPN not to use this DNS service as it already uses it behind the scenes.

I use mullvad and I'm too dumb to understand what this means. Can one of lemmy's many IT experts ELI5?

[–] pelya@lemmy.world 1 points 10 months ago

This makes it harder for russian military to steal one of Mullvad servers to track your porn usage over VPN - once they unplug it, all links to porn will be gone.
