## Can you target specific spells with Greater Dispel Magic? How many?

Greater Dispel Magic works as Dispel Magic for the Targeted Dispel option.

This functions as a targeted dispel magic, but it can dispel one spell for every four caster levels you possess, starting with the highest level spells and proceeding to lower level spells.

Additionally, greater dispel magic has a chance to dispel any effect that remove curse can remove, even if dispel magic can’t dispel that effect. The DC of this check is equal to the curse’s DC.

Nestled in the Dispel Magic Targeted Dispel option is the ability to choose which spell you dispel

You can also use a targeted dispel to specifically end one spell affecting the target or one spell affecting an area (such as a wall of fire). You must name the specific spell effect to be targeted in this way. If your caster level check is equal to or higher than the DC of that spell, it ends. No other spells or effects on the target are dispelled if your check is not high enough to end the targeted effect.

Does Greater Dispel Magic inherit this clause? If so, do you have to select one spell to roll multiple checks against or do you select one spell per check?

## Parallelism not engaging on specific database

I have a few databases with identical schemas, lets call they:

DB_A

DB_B

I have a query that when run takes 11 seconds and returns 11.000 records on DB_A but when the exact same query is run on the identical DB_B it takes 40 seconds and returns 7.000 records.

The schema is identical so is the query but when i run it on DB_B it runs on Degree of Parallelism 1, on DB_A it runs on 16.

I tried setting the cost of threshold to 0 to force parallelism but got the same result.

Why is that? How can the same query running on cloned databases behave so differently?

Any ideas are welcome.

Im using SQL 2017 Standard.

## Does an envoy warforged have to choose a specific vehicle?

We know from the accepted answer to this question that envoy warforged can choose a vehicle for their integrated tool. However, on the table on page 154 of the Player’s Handbook, “Vehicles (land or water)” is listed as one type of tool.

So, question(s):

1. Can the warforged choose the vehicle type each time they use the ability(longboat, rowboat, etc.)

2. If the answer to the previous question is yes, does the warforged have to choose land or water vehicles at character creation, or can they use both interchangeably (because “Vehicles (land or water)” is listed as one type of tool, but uses “or”, which can be inclusive or exclusive)?

## Creating a specific hash setup

While solving a practice exam, this is the question I could not answer. Any help is appreciated. I am new to hashing and have no idea how to solve this question.

Let $$H$$ be a $$(0.15, 0.85, 0.9, 0.1)$$-sensitive family of hash functions. Suppose we use 60 functions from $$\cal{H}$$ to sign the documents and apply an AND followed by OR construction using $$b$$ bands and $$r$$ rows within each band (hence $$b$$ and $$r$$ are whole numbers with $$b \cdot r = 60$$).

For any two documents to be considered a candidate pair, their signatures will need to match in all the $$r$$ rows of at least one band. For a similarity threshold of $$0.15$$, we would like the construction to yield a false positive rate of at most $$0.05$$ and for a similarity threshold of $$0.85$$, we would like the false negative rate to be at most $$0.1$$ – explain clearly whether or not this is possible, and if so, to provide appropriate values for $$b$$ and $$r$$ that will achieve the desired rates.

## c# – Setup specific mousewheel rules and timer with reset function to control a value with minimal user input

My main issue here is to distinguish a first and a second stage when moving a mousewheel up and down.
How could I put the following together for a mousewheel solution in plain c#?
I have a value that controls the opacity level of an object and it could be a value between 1 – 255.
I started with a simple mousewheel setup so that each time the wheel jumps to its next spot upwards or downwards, another value returns a 1 or -1. What I need is moving the wheel up or down 1 time will start a timer event that changes the opacity value to the minimum or maximum value depending on wheel movement direction by adding/subtracting 1 to the current value every 1ms. For up direction, stop value increase only when the wheel was moved to the next spot upwards or when the value is 255. For down direction, stop value decrease only when the wheel was moved to the next spot downwards or when the value is 1.

## prove a specific language is in RE and R

i have Count(M) and a finite number k. M halts on an input w after k steps.

i need to prove that the language L is in RE, and to prove it`s in R. L= { < M > | Count(M) is an infinite group}

My idea for a solution starts with: even though L is an infinite language, it contains Count(Mi) that halts eventually. each M in L must halts, and Count(M) is infinite.

so, in order to prove L in RE, can i simply say every M in L halts eventually? im pretty much stuck with it. any directions please?

## Is there a way to forward unknown land line callers to a specific number in a manner similar to nomorobo?

My parents are getting up there in age and recently, my dad asked me about a message on his answering machine from “Apple” saying his account was “compromised”. After having educated him on phishing calls, I’m somewhat exasperated that he thought the message was authentic, so I had an idea to manually screen calls for him that aren’t from a whitelist.

I looked through the features from his landline voice provider to look for an unknown caller forwarding option, but there does not appear to be a way to forward calls from callers not on a whitelist. You can only forward specific callers or all callers. Nor did I want to enable the ‘accept selected callers’ feature because there’s no way to screen legitimate calls, including calls from 911.

I set up nomorobo for my parents about a year or so ago (but it doesn’t seem to block spoofers like the “Apple” caller) and I was wondering if there was some service that did something similar, but instead of working from a list of known scam numbers and block them, I’d like it to check the caller against a whitelist I set up and if not on the whitelist, forward the call to me and allow me to decide whether to let the call through or not (e.g. press 1 to add the caller to the whitelist and forward the call back to my dad – or 2 to blacklist them & hang up).

As a person with elderly parents and increasing phishing on the elderly, it seems like such a service would be popular, at least for this niche group. I found a service in the UK called “Fuss Free Phones” that has operators that essentially do what I’m proposing, but they’re shutting down (probably because it’s a bad business model to employ real-person operators to handle today’s scam volume). But if you crowd-source the “operators”, to those who actually care about the person being called, maybe it could work.

## Is it possible to hijack specific e-mail with remote access?

I don’t know exactly how to ask this but I was recently presented with e-mails that look like they came from my e-mail and IP address but I didn’t send them and never saw them. It is a back and forth correspondence with another gmail account. Is it possible someone was able to set up a forwarding without my knowing and make it look like it was coming to and from me? I did find that someone had snuck in AnyDesk and had remote access to my laptop during this time, so they had access to everything.

## Is “this damage cannot be reduced of prevented in any way” a catch-all, or is “reduced or prevented” referring to specific game mechanics?

There are a number of spells that deal non-preventable damage. However, this non-preventable damage is worded as “This damage cannot be reduced or prevented in any way”. Damage reduction and damage prevention are AFAIK both specific mechanics that are more or less standardized, with spells, feats and equipment that grant these effects explicitly using these words.

It feels to me like non-preventable damage only stops effects that are explicitly worded as “reduces damage taken” or “prevent all damage taken”, and that effects that use other words to affect the damage taken by the player may actually be able to stop the damage. For example, AFAIK D&D 5E has both damage reduction and damage resistance. However, I don’t know if this is a correct interpretation.

So the question I have is: does “reduced or prevented” in this case explicitly refer to effects worded using the words “reduces damage taken” or “prevent all damage taken”, or do they also refer to other effects that reduce or prevent damage with other words?

## How to configure sharepoint search for specific lists etc

I have a requirement where they just want sharepoint search to return results from specific lists etc..(and some specific content only compared to the OOTB search result that returns everything)

Some of my ideas below

1. I was thinking configure out of the box search and setup some scope with specific result source and then use the webpart to display the search result. is this ideal?

2. use Search API. Will this require a lot of using scripts etc..

Anyone done something similar and if yes any tips or ideas would be appreciated
