## Does detect magic detect itself?

So I cast detect magic in a circle around myself, can I see the aura of my own spell and thus know where it ends?

• Any SEO benefit to a page linking to itself? 1 answer

I want to know if I get a link to the same page, how would it affect the SEO for that page? Is it a good practice or bad?

for example : making this link “site.com/aa” to the same page “site.com/aa”

## WordPress plugins always deactivates by itself after “Database is required” loop

After updating the latest update in wordpress, this “Database is required” loop keeps going and it deactivates the plugins. I already tried the solution that the other sites/forums gave which is to have the same db_version in my version.php and wp-options. Up until now, it doesn’t work. Any available solutions?

## Does homomorphic encryption hide the algorithm itself?

The question is rather simple, but finding resources and answers quite tricky. Homomorphic encryption should enable us to compute over encrypted data. What if the algorithm for computing should be kept in secret as well? Given we have a functioning homomorphic encryption in place, is the algorithm which is applied to the input data also secure?

Is it possible for an intruder to understand how the data is computed and learn about the algorithm, given the intruder has access to the program which does the computation?

## DNS Secretly Resets Itself Instantly and DNS Servers are Not Blocked by Windows 10 Firewall Rules

I noticed that on a Windows 10 machine I if I leave DHS to be auto-configured or change the DNS serves to OpenNIC addresses they are automatically reassigned to

8.8.8.8

75.75.75.75

Malware scanners are not detecting anything, but colleagues say it is a known attack vector to defeat DNS anonymity.

Only SpyHunter detects and reports this change, though I previously found evidence of this by testing. It also seems to override DNS configured by VPN software. It is forcing itself at the top of the list, so it always checks Google before considering OpenNIC as a fallback.

As a mitigation step I tried custom Inbound/Output firewall rules to block all traffic in a wide range of either IP, but these rules seem to fail because I can still ping those IP’s.

How can I find and fix the root cause and/or how can I completely block all DNS traffic to these IP’s?

## Variable derives itself

Can anyone explain me how is this true? T =>* T with this grammar

R -> XRX | S
S -> aTb | bTa
T -> XTX | X | $$\epsilon$$
X -> a | b

## Does Bleed Damage stack with itself from different sources?

Does bleed damage stack with itself from multiple sources?

## Algorithm for mapping objects of list without mapping to itself?

I want to map objects of a list, to objects of that same list, randomly, without ever mapping any given object to itself.

So given a list of objects [a, b, c] valid maps would be, for example:

   a -> b,    b -> c,    c -> a 

or

   a -> c,    b -> a,    c -> b 

an invalid mapping would be:

   a -> a,    b -> c,    c -> b 

I just cannot figure out how to implement such an algorithm.

(This is for a small Secret Santa app that I am building where each person will be assigned to buy gift to one of the other participants.)

## Can the target of Nature’s Wrath (Channel Divinity) use an action to attempt to free itself?

An Oath of Ancients Paladin may use her Channel Divinity class feature to apply Nature’s Wrath:

Nature’s Wrath: As an action, you can cause spectral vines to spring up and reach for a creature within 10 feet of you that you can see. The creature must succeed on a Strength or Dexterity saving throw (its choice) or be restrained. While restrained by the vines, the creature repeats the saving throw at the end of each of its turns. On a success, it frees itself and the vines vanish.

If a creature fails the initial save and becomes restrained, can it use its action to attempt to free itself on subsequent turns (similar to how a grappled creature can use its action to attempt to escape the grapple)?

Or is it only allowed to escape by passing the save at the end of its turn(s)?

## Does the UA Blade Mastery feat stack with itself?

The Blade Mastery feat says this:

You master the shortsword, longsword, scimitar, rapier, and greatsword. You gain the following benefits when using any of them:

• You gain a +1 bonus to attack rolls you make with the weapon.
• On your turn, you can use your reaction to assume a parrying stance, provided you have the weapon in hand. Doing so grants you a +1 bonus to your AC until the start of your next turn or until you’re not holding the weapon.
• When you make an opportunity attack with the weapon, you have advantage on the attack roll.

Its second feature says that using your reaction, you can get a +1 bonus to AC. This lasts until you’re not holding your weapon. Does this mean that in multiple consecutive rounds you can use your reaction to get a +1 bonus as long as you’re holding the weapon, which could (theoretically) allow you to have, for example, +6 to AC after a minute like this? Or can the bonus only apply once, RAW?
