tls – Check the installers downloaded via HTTPS

An attacker with a man-in-the-middle position who is able to silently intercept and change HTTPS traffic (which is not possible in practice) can actually provide a user with a modified executable file with a modified hash and provide a compromised GPG key.

However, if you were really paranoid, you would not download the GPG key that created the signature over the same connection that was used to download the executable file. Instead, you would download the executable file at home, for example, and then download the GPG key in an Internet café.

As you can see, this is not really done in practice and there is usually no need to do so. TLS is considered if configured correctly safe in practice by today's standards.

So what should be done in practice?

In practice, you have several options:

  • Option 1: Ignore hashes and GPG signatures and trust the download is fine.
  • Option 2: Check the attached checksum to make sure that no errors occurred while downloading. This is what I personally do with OS downloads and the like.
  • Option 3: Download the GPG key gpg --verify and see if everything is ok.
  • Option 4: Download the executable file to a computer and move it to another location to download the GPG key. Then, meet with the supervisor to check the fingerprint of the key. Then check the download.

As you can see, the examples are becoming more and more complex to contain increasingly ridiculous risks. In the end, you have to choose your own level of paranoia.

sharepoint online – Invoke a specific URL based on drop-down and check box selections

I have this code, which switches to this URL when users select a specific value. But I only have the HTML part.

For example:

Urgency = high ||
Impact = Location / Department ||
Platform = Unix & Windows

If you click Submit, they will be redirected to a URL based on those selections

It's like High + Site / Dept + Unix & Windows = URL1 …. and so on.

I only have the HTML codes that I found during my research, but I'm not that good at Javascript, so I do not seem to find the logic of how this works.

I also use the Sharepoint Web Part Content Editor

I can not add the code here, so I just put it on the link below

Link for the code

Example conditions:

I hope the following conditions answer your question. But it's a lot, so I gave a few examples

Urgency & impact = show all; Platform = All checked => Homepage

Urgency = high & impact = show all; Platform = All marked => URL1

Urgency = Low & Impact = Show All; Platform = All marked => URL2

Urgency = Show All & Impact = Location / Department; Platform = All marked => URL3

Urgency = Show All & Impact = Multiple Users; Platform = All marked => URL4

Urgency & impact = show all; Platform = Unix & Windows => URL5

Computability – Can I check if the length of a C program that can generate a string is below a certain number?

I was asked this question:

Complexity (S) is the length of the smallest C program that generates the string S as output. Is the question "Complexity (S) <K" decidable?

In terms of decidability, I only know the Halting problem and just learned about Rice's theorem while searching online (although I think it can not be applied here?). I could not reduce the problem to an indefinite problem that I know about. Thanks in advance for any help

macos – Apple Script – How do I check if the borders of a window match specific values?

The following example AppleScript code uses the value of bounds to the Note in your operating room, to check if the electricity bounds corresponds to the given one list:

tell application "Notes"
    if (bounds of front window) is not equal to {0, 0, 540, 300} then
        set bounds of front window to {0, 0, 540, 300}
    end if
end tell

It can also be written like this:

tell application "Notes" to ¬
    if (bounds of front window) ¬
        is not equal to {0, 0, 540, 300} then ¬
        set bounds of front window to {0, 0, 540, 300}

Or with one variable assignment:

tell application "Notes"
    set checkBounds to bounds of front window
    if checkBounds is not equal to {0, 0, 540, 300} then
        set bounds of front window to {0, 0, 540, 300}
    end if
end tell

Note that example AppleScript code is exactly that and contains none error proper handling. It is the responsibility of the user to add one error handling as needed, need or desire. Look at that To attempt statement and error statement in that AppleScript phrasebook, See also, Work with errors,

How to Check the Runtime Environment (Python 3.5)

I have a project that I'm developing in the PyCharm environment, and I was wondering if you could use the script to see if I'm in the Pycharm environment or in the terminal. because I want to add the command to delete the screen
system ("clear")
& # 39; & # 39; & # 39;
I wanted to be able to do something like that
if inBash:
system ("clear")
& # 39; & # 39; & # 39;
Does anyone know how to do this?
