QUESTION
For the last week or so I have been struggling to find a resource that will allow me to make something like the 2D petrie polygon diagrams in this article.
My main trouble is finding out what the rules are for the edge and node connections.
I.e. in this plot, is there a simple way to make the image from scratch (even if it not fully representative of the bigger theory behind it)?
Any help is massively appreciated!

QUESTION
I'm trying to script removing the modify permission of a particular folder (or file) for the "NT AUTHORITY\Authenticated Users" group, across multiple machines (actually as part of a file deployment script). I have some code that attempts to do this, but it is not working as expected.
Context:The script copies down a file structure locally, and a particular file (ideally the whole folder structure) needs to be made unmodifiable (by non-admins). Setting the read-only setting isn't sufficient, since it can be reverted by those with modify permissions to the file.
My attempt: ...ANSWER
Answered 2021-Feb-10 at 23:21Turns out my problem was that the folder was inheriting the modify permission from C:\
. Apparently modifying permissions when inheritance is enabled simply does nothing and throws no errors (>:/). The solution was to disable inheritance on the folder first (copying the existing permissions), and then the rest of the code works as expected.
In my case, simply removing all permissions for NT AUTHORITY\Authenticated Users
entirely was sufficient (and easier than performing modifications on the existing permissions), since BUILTIN\Users
still has read permissions.

Question: How do you associate a Network Interface Card
of an Azure Virtual Machine
to an Application Security Group?
This official tutorial from MS Azure team describes how to add the network interface
for a VM
to one of the application security groups the tutorial has created previously. According to the tutorial, in the Azure Portal
, you go to your myVmWeb VM==>SETTINGS ==> Networking
. Then, Select Configure the application security groups
as shown in image 1 below.
But when I follow these steps, I get the image 2 (shown below) that does not have the option Configure the application security groups
. Moreover, all other tutorials that I searched online (such as this and this) showing the same image 1 that MS Azure team's tutorial is showing. So, what I may be missing here or is there any other way to associate a VM's NIC to an Application Security Group?

I need help with a code that takes a user's input of specific columns they want from a large csv file I have. After they type in themselves a column they want, they also must type an integer input. That integer input will give them that number of results of the lowest occurrences for that column. For example if they type: hospital_name, "5", it will show them 5 different hospitals(there are at least 50 different hospital names under that column) that have the lowest count tied with them. I will write an example input and output:
Type in which column you want: hospital_name Type in how many lowest results you want: 3
An output may look like:

I've been using Vis.js recently to display a Petri-net model. I was able to animate petri-net token over the edge from the given model.
However, the animation was agitated.

QUESTION
I've read here that Microsoft is deprecating WMI. I need to start a project in .NET Core and query information from Windows, e.g. Win32_OperatingSystem
or Win32_LogicalDisk
.
I'v read that you should avoid Get-WmiObject
in PowerShell and use Get-CimInstance
instead. What (which Nuget/library) should be used in .Net Core now to query those kind of information?
ANSWER
Answered 2020-Mar-05 at 17:33You can use the Windows Compatibility Pack (article, nuget) for .NET Core which gives you access to a lot of Windows-only APIs but restricts your app to running only on Windows, probably not something you're worried about. This compatibility pack is also known as platform extensions. With this you would need to learn how to use the classes in the System.Management
namespace (API Ref, example code 1, example code 2). Keep exploring the API for examples.
Additionally, it looks like there is a newer cross-platform open-source system similar to CIM made by Microsoft. Though apparently not everything available in WMI is available with this, so your mileage will vary: https://www.nuget.org/packages/Microsoft.Management.Infrastructure/
Hope this helps.
QUESTION
I made a little diagnostic script that I keep in my $profile
. In collecting the CPU name I found that the command takes about 4 seconds (Get-WmiObject -Class Win32_Processor).Name
. So I thought I'd try PowerShell Jobs and while I think they will be really good for long background jobs, if you just want to quickly grab a small piece of information in the background, the initialisation times are awkward (like 2-3 sec per job) so I thought I'd use Start-Process to dump values in temp files while the rest of my script runs. I think I'm doing this correctly, but if you run this function 3 or 4 times, you'll notice that CPU name is not populated.
• Is using Start-Process like this optimal, or does anyone have a quicker way to just start small jobs in the background in parallel? I know there is a .NET way of doing this (but it seems super-complex from what I've seen)?
• Do you know why my "wait for file to be created and be non-zero before accessing it" is failing so regularly?

QUESTION
I am face a problem that took me a lot of time and I do not resolve it yet, the problem is how does modelisation look like with Petri nets for an application writen in python? and if there are any exemple of couple of code and Petri nets representation(modelisation) please show me, so thank's for all of you.
I know that Petri nets compose of arrows, states(places) and transitions(events)
...ANSWER
Answered 2019-Nov-20 at 21:48You cannot just translate any random program - no matter what language - into a Petri net model. Models are abstractions, so you have to decide which states of your program are important enough to become part of the model. Then you have to figure out how to represent these states with tokens in places. Then you have to figure out how to describe the state changes with transitions.
Does this sound all too vague to you? That's because your question is too broad. Your Python application could be a text editor, an HTTP server, a particle simulator, a chess game. We cannot help you to create a model without knowing what you're trying to model.
QUESTION
The goal of the code I'm going to present is to create a aux vector that will contain petri nets transitions, arcs and places. I'm dividing a petri net into several groups, each group is a transition with respective input arcs and places.
The issue is the following: After I put the info in the first position of the aux vector, I'm unable to put a place with the same id of the place of the previous group. For example, if I have a transition with place_id=1 and place_id=2, and the next transition have place_id=2 and place_id=3, the code doesn't write the value place_i=2 in the vector for the second group.
