## Extract all Rules from Plot function

Let’s say I would like to know all the Rules that apply to PlotTheme->"Detailed". I tried

Select[FullForm[Plot[x, {x, 0, 1}, PlotTheme -> "Detailed"]], Head[#] == Rule &, Infinity] 

but I get the Error/Warning that FullForm was called with 0 arguments, which doesn’t make sense to me. What would be the correct way to do this?

## Does anyone here know how can we extract Lambda from the following equation

I am working on an estimation problem where I have the following

Code is

A = 1 + Pi*Csc[(1 + Pi)*\[Lambda]]^2*     (Pi + Sin[2*(1 + Pi)*\[Lambda]]) 

Can anyone help me how can we extract $$\lambda$$ from this equation in Mathematica?

## Will revivify work on a creature killed by Extract Brain?

Mind flayers (Monster Manual, p. 222) have the Extract Brain action:

Extract Brain. Melee Weapon Attack: +7 to hit, reach 5 ft., one incapacitated humanoid grappled by the mind flayer. Hit: The target takes 55 (10d10) piercing damage. If this damage reduces the target to 0 hit points, the mind flayer kills the target by extracting and devouring its brain.

If a mind flayer kills a creature with their Extract Brain action, will revivify return the creature to life as normal?

## Is it safe to extract file from potentially infected disk

I have a hard drive used for years, there are windows and many personal files on it. What I called "files" are images, musics, documents (pdf or docx), but not programs. All the "files" were not initially infected. As I said in the title, the hard drive may be infected by malware (I did not safely use it).

My question is : can I extract these personal files on a safe computer without risk of contamination ? In other words, may these files be infected and spread malware ?

## unity : How to control the tile value of a material when extract material from imported game object (fbx, blend etc)

I import .blend (or .fbx) file into unity and i extract the materials. Sometimes the rusult of the material tiling is 5×5 , sometime 1×1. What makes unity decide what tiling value to be used when extracting material ? Can we control it ? i’m confused because normally it’s 1×1 but at some case the material has tiling of 5×5.

## Seeking tools that can extract PostgreSQL data

Is there any tool that can extract data from PostgreSQL data files, and these data can be imported into other PostgreSQL databases?

## How to extract IV from ciphertext in XML

I have received an encrypted XML document, that contains a. An encrypted session key – this was encrypted using my public key. I have succesfully decrypted this using:

const decryptedSessionKey = crypto.privateDecrypt( { key: privKey, padding: crypto.constants.RSA_PKCS1_PADDING }, encryptedString );

b. The actual Ciphertext (UTF-8 encoded, 85228 is the character length)

c. The w3 specs suggest that the Initialisation Vector is prefixed to this cipher text, so I converted the cipher text to a Buffer, and sliced the first 16 bytes to create the IV. I then used:

const xmlIV = Buffer.from(message.slice(0, 16), ‘utf-8’);

const cryptoIv = Buffer.alloc(16, xmlIV); // Initialization vector.

const decipher = crypto.createDecipheriv(cryptoAlgorithm, decryptedSessionKey, cryptoIv);

// message.slice is removing the prefixed IV.

let decrypted = decipher.update(message.slice(16), ‘binary’, ‘binary’);

try {

Buffer.concat(decrypted, decipher.final('binary')); 

} catch (err) {

console.error('Authentication failed!'); 

}

console.log(decrypted)

Decrypted is a buffer of length 85200 – which is 12 characters shorter than the message. And converting it to a utf-8 encoded string returns corrupted text.

Any superheroes out there who could help troubleshoot this ? Many thanks!

## John the Ripper: Cannot extract hash from PDF because Python keeps opening?

I’m having a really strange issue. I’m attempting to extract a hash from a user-password encrypted .pdf with John the Ripper’s pdf2john tool, but every time I run the command:

c:\...\run\pdf2john.pl mypdf.pdf 

My Python IDE (Visual Studio Code) opens up the pdf2john.pl file and the following appears in the command line:

[main 2020-06-18T10:02:06.775Z] update#setState idle (node:15044) Electron: Loading non context-aware native modules in the renderer process is deprecated and will stop working at some point in the future, please see https://github.com/electron/electron/issues/18397 for more information [main 2020-06-18T10:02:36.776Z] update#setState checking for updates [main 2020-06-18T10:02:36.934Z] update#setState downloading 

Any ideas on how to stop my IDE from opening up and having the command actually work as expected? The latest version of Perl is installed on my machine.

## Is it possible to extract an Instagram password hash? [closed]

I have lost access to my instagram account, it might’ve been hacked and I am trying to regain access. The problem is that I don’t have access to the email I used to create an account and neither have I linked it to the Facebook. Support also wasn’t helpful. Therefore I decided I’d give it a go.

I’ve launched a dictionary attack against it but considering its limitations, I would also like to explore other options.

I thought that I might have more luck deciphering the hash. Is it possible to extract instagram’s password hash associated with my account and if yes, how to do so? Are there any other things I can try?

Thanks!
