Non microsoft vscode ie VsCodium

C:\Users\h.vscode\extensions : contains extensions for vs code

C:\Users\h.vscode-oss\extensions: contains extension for vscodium

here h is username

Not all extensions are available so just transfer extensions from vs code to vscodium manually.

use package manager to install vscodium.

for windows use:

winget install vscodium
- comments
  
  @Existentialist
  There is a trick for that. I have both vscode and vscodium installed. If desired extension is not avaiable in vscodium extension store then i download it from vscode store and copy its folder from .vscode/extensions to .vscode-oss/extensions.
Multiple vs code

changing extension directory:

https://stackoverflow.com/questions/40080793/is-there-a-way-to-change-the-extensions-folder-location-for-visual-studio-code

What I did - after installing Visual Studio Code for the first time, I checked the documentation and added at the end of 'Target' field of editor's shortcut the following (there's a space before the two dashes):
```
 --extensions-dir="DRIVELETTER:\VSCODE\extensions"
 --user-data-dir="DRIVELETTER:\VSCODE\settings"
```
where DRIVERLETTER and VSCODE are the corresponding drive and directory where Visual Studio Code is installed. So mine looks like this:
```
"D:\Microsoft VS Code\Code.exe" --extensions-dir="D:\Microsoft VS Code\extensions"
```
Here is for the user data directory:
```
"D:\Microsoft VS Code\Code.exe" --user-data-dir="D:\Microsoft VS Code\settings"
```
Accessing the 'Target' field is done by right-clicking the shortcut and choosing 'Properties'

Anyway, there's a simpler solution to that problem - just use the portable version of Visual Studio Code. It works under Windows, Linux, and macOS:

for windows:
```
@START  codium --extensions-dir="C:\Users\hp\Videos\imp\web\extensions"  --user-data-dir="C:\Users\hp\Videos\imp\web\User"
```

Permanent deletion of files in android

With the increasing cases of identity theft and data breaches, it is certainly important to know the right way to dispose our data. Well, if you want to permanently delete your photos and videos from your phone, then I would recommend the following solutions.

Delete media files manually

Well, the easiest solution would be deleting your photos and videos manually from your device. Just go to the Gallery app and select what you wish to get rid of. Afterward, make sure that you visit the “Recently Deleted” album where your photos are saved temporarily. Now, delete your photos from here as well to remove them permanently.

Factory Reset your Device

If you want to permanently delete everything from your phone, then consider performing a factory reset. If you have an iPhone, then just go to its Settings > General > Reset for this while Android users can find it in Settings > Reset as well. This will erase not just photos, but all the saved content and stored settings from your phone.

Use a Professional Data Eraser

If you just factory reset or manually delete your photos, then anyone can extract them using a data recovery tool. Therefore, if you are concerned about your privacy, then consider using dr.fone – Data Eraser. There are dedicated applications for both iOS and Android that you can try. Using them, you can connect your device, and follow a simple click-through process to completely wipe your data. This will erase all your photos and videos beyond the scope of recovery.

Sublime Text Palenight theme missing fix

The Palenight theme is not included in the Midnight theme package. You need to install the Palenight theme separately. You can do this by following these steps:
1. Open Sublime Text and go to Preferences > Browse Packages.
2. In the Packages directory, create a new folder called Palenight.
3. Clone the Palenight theme repository: https://github.com/jbrooksuk/palenight-sublime-text into the Palenight folder.
4. Restart Sublime Text.
The Palenight theme should now be available in the Color Scheme menu.

Here are some additional troubleshooting steps you can try if the Palenight theme is still not available:
- Make sure that you have installed the latest version of the Palenight theme.
- Verify that the Palenight folder is located in the Packages directory.
- Restart Sublime Text multiple times.
- Clear your Sublime Text settings.

docker build -t username/first_app:1.0

it will produce an output and will produce image starting with sha……

To run the image use:
docker run <image_name/code>

Now if we try to run it with port(here in eg port is 8080) then it wont run because by default its not accessible outside container so to expose it we can use port forwarding.

docker run -p 5000:8080 <image_name/code>

port 8080 of container is forwarded to port 5000 of outside container. 5000:8080 is mapping
- For publishing
  
  Now login through the CLI by executing:
```
docker login
```
  Push your Docker Image to the Docker Hub repository with the following command:
```
docker image push <repository>/<image>:<tag>
```
  Example:
```
docker image push dhanushkamath/dockerize-node:1.0.0
```
  You’ve successfully published your first image to the world!
  
  Running this container on a different computer that has Docker only requires a single command:
```
docker run dhanushkamath/dockerize-node:1.0.0
```
RSA

https://www.geeksforgeeks.org/rsa-algorithm-cryptography/

Note: If your public key's n (modulo) is 4096 bits, then your message can't exceed 4096 bits (realistically even less because of padding)
```
Select two prime no's. Suppose
P = 53 and Q = 59.
Now First part of the Public key  : n = P*Q = 3127.
```
```
But e Must be An integer.Not be a factor of Φ(n).  1 < e <Φ(n)
Φ(n) = (P-1)(Q-1)     
      so,  Φ(n) = 3016
Eg: For e=3, Φ(n)%e !=0 so e is not factor of Φ(n).
```
```
 Now calculate Private Key,d
 d = (k*Φ(n) + 1) / e for some integer k

or 

D*e mod φ (n) = 1
at k=2,
(2*3016+1)/3 =( 6032+1)/3=6033/3= 2011
d=2011
```
Public Key= <e,n> = <3,3127>

Private Key=<d,n> <2011,3127>

Encryption:

(m^e)mod(n) here a mod b = a%b ⇒ mod is modulus operator

m=3

(3^3)%3127=27%3127=27

c=27

Decryption:

  - Stack overflow
    
    Let's say M is the modulus. So YES, you could first perform intermediate = 65^e, and finally compute intermediate mod M. And of course, intermediate would be a very very very very big integer (if e equals 65537, the decimal representation of intermediate contains 118813 digits!).
    
    BUT, thanks to a very basic modular arithmetic theorem,
```
(65^e) mod M = ((((65 mod M) * 65) mod M) * 65) mod M [...] (e times)
```
    (the theorem states that in a quotient ring, the n-th power of the class of an element is the class of the n-th power of the element)
    
    As you can see, this does not need any very big integer library, since after each arithmetic product, you use mod M that returns an integer between 0 and M-1. So, you only have to compute arithmetic products of integers less than M.
    
    As an example, here is a simple shell script (bash) that computes 65^65537 mod 991*997. As you can see, no need to get a big number library:
```
#!/bin/bash

# set RSA parameters
m=65           # message to encode
M=$((991*997)) # modulus (both 991 and 997 are prime numbers)
e=65537        # public exponent (coprime with 990*996, thus compliant with RSA algorithm)

# compute (m^e) mod M
ret=1
for i in {1..$e}
do
  ret=$(((ret*m)%M))
done

# display the result
echo $ret
```
    It immediately returns 784933, thus 65^65537 mod 991*997 = 784933
    
    The biggest integer computed with your method of calculus has 118813 digits, but the biggest integer handled with this shell script only has 12 or less digits ((M-1)^2 is made of 12 digits).
    
    According to these explanations, we can now answer your question:
    
    My question is then, for the working RSA algorithm, what size (number of digits) number does that algorithm pick?
    
    With the above explanations, you can see that the maximum number of digits in the decimal representation of integers you have to manipulate is 1+log10((M-1)^2), because you will, at most, compute a product of two integers between 0 and M-1.
    
    Note that 1+log10((M-1)^2) = 1+2.log10(M-1) < 2+2.log10(M) = 2.(1+log10(M)). Also note that 1+log10(M) is the number of digits of M.
    
    Therefore, as a conclusion, this proves that the number of digits your library has to handle correctly is twice the number of digits of the modulus (if you are computing the exponentiation using integer multiplications the way explained here).
  Calculate Large Exponents
  
  Calculating large exponents and modular arithmetic can be complex. For such calculations, you can use a calculator or programming language with built-in support for handling large numbers and modular arithmetic. In this case, you're looking to calculate 56^{2346} \mod 564562346mod564.
  If you want to do this using a programming language like Python, you can use the pow() function along with the modulus operator %:
  
  pythonCopy coderesult = pow(56, 2346, 564) print(result)
  
  If you don't have access to programming tools, you might need to use a calculator that supports large number calculations and modular arithmetic. Many scientific calculators and online calculator tools have this capability. Just make sure to enter the values and operations correctly.
  Keep in mind that the result will be a large number, so ensure you're using tools that can handle such calculations accurately.I mean arent there any mathematical properties to handle thisChatGPT
  Yes, there are mathematical properties that can help simplify and handle calculations involving large exponents and modular arithmetic. One property that's particularly useful is the modular exponentiation property. This property states that for any positive integers aa, bb, and mm, you can compute a^b \mod mabmodm efficiently without actually calculating the huge exponentiation.
  
  Here's the general idea:
  1. Start with a result variable initialized to 1.
  2. Iterate through the binary representation of bb, from the least significant bit to the most significant bit.
  3. For each bit, if it's 1, multiply the result by aa and take the result modulo mm.
  4. Square aa and take the result modulo mm in each iteration.
  5. The final result will be a^b \mod mabmodm.
    This method significantly reduces the number of multiplications and calculations required compared to naively calculating a^bab and then taking the modulus.
    For example, to calculate 56^{2346} \mod 564562346mod564, you would apply the above steps using a = 56a=56, b = 2346b=2346, and m = 564m=564.
    However, this approach still involves some complex calculations. If you're not comfortable performing these calculations manually, it's best to use a programming language or calculator with built-in support for modular exponentiation.Ok so use these steps to solve this ChatGPT
  Main:
  
  Certainly! Let's use the modular exponentiation property to calculate 56^{2346} \mod 564562346mod564:
  1. Start with the result variable res = 1res=1.
  2. Convert the exponent 2346 to binary: 2346_{10} = 100100101010_{2}234610=1001001010102.
  3. Iterate through the binary representation of the exponent:
    ◦ First bit: 00. Square 56 and take the result modulo 564.
    ◦ Second bit: 11. Multiply 56 by 56, take the result modulo 564, and then square the result.
    ◦ Third bit: 00. Square the result again.
    ◦ ...
  4. After iterating through all bits, the final result will be res = 56^{2346} mod 564
    Using the steps above, you can perform the calculations iteratively:
  5. res = 1
  6. res = 56^2 mod 564 = 3136 mod 564 = 220
  7. res = 220 * 56^2 mod 564 = 220 * 3136 mod 564 = 4476 mod 564 = 348
  8. ... (continue squaring and multiplying as per the binary representation of the exponent)
    After completing all the steps, the final result res will be the value of 56^{2346} mod 564
  Taking another example:
  
  2^9 mod 100
  
  9=1001 in binary form
  
  res=1
  
  If bit is:
  
  1: multiply by base which is 2 here ⇒ res*2
  
  0: square it ⇒ res^2
  
  from right to left:
  
  First significant bit(rightmost) ie 1: res=res*2 mod 100=2 mod 100 = 2
  
  2nd bit ie 0: res=res^2=4 mod 100 = 4
  
  3rd bit ie 0. res=res^2= 4*4=16 mod 100 = 16

Google DRM Dangers
1. What will happen basically that google will decide that which browser, which OS, which extension u can use also forcing to use Cam and microphone
2. So u can no longer block ads, extension to save our system from virus thus stealing your information and selling it.
  Internet will no longer be open anymore.
3. Get commerce sites, banks, and digital content providers to widely adopt WEI for security benefits.
4. Require use of TPM signed OS to access said sites "securely".
5. Only sign systems with locked down execution environment to ensure integrity of system.
6. Censorship, spying, marketing and who knows what else.
7. malicious websites can then filter out traffic they don't want, and instead focus entirely on their specified victims.
8. search engine scrapers being unable to gather data. so no new search engine will ever develop.
9. this may affect dissidents and journalists that use secure software (TAILS, tor, etc) to communicate sensitive information. said secure software would probably not succeed a WEI test, and could thus make their work even more difficult than it is
Asking the user if they’d like to receive notifications the instant they visit a site is so dumb. As soon as the user hits no, that’s it, they’ve now been indefinitely banned from requesting that permission moving forward. Regardless of if the user might actually want it some day later on.

Safetynet will detect rooted device and block its access for banking apps

1, don't worry this is just an idea
2, don't worry this is just some personal project
3, don't worry this is just an internal discussion
4, don't worry this is just a closed test
5, yaaaaaa you have to update or you'll die, byyyyy
- chat
  
  It's a DRM to be launched by google giving websites access to our device information.
