I wish to suggest (perhaps enforce, but I am not firm on the semantics yet) a particular format for the output of a PowerShell function.

about_Format.ps1xml (versioned for PowerShell 7.1) says this: 'Beginning in PowerShell 6, the default views are defined in PowerShell source code. The Format.ps1xml files from PowerShell 5.1 and earlier versions don't exist in PowerShell 6 and later versions.'. The article then goes on to explain how Format.ps1xml files can be used to change the display of objects, etc etc. This is not very explicit: 'don't exist' -ne 'cannot exist'...

This begs several questions:

1. Although they 'don't exist', can Format.ps1xml files be created/used in versions of PowerShell greater than 5.1?
2. Whether they can or not, is there some better practice for suggesting to PowerShell how a certain function should format returned data? Note that inherent in 'suggest' is that the pipeline nature of PowerShell's output must be preserved: the user must still be able to pipe the output of the function to Format-List or ForEach-Object etc..

For example, the Get-ADUser cmdlet returns objects formatted by Format-List. If I write a function called Search-ADUser that calls Get-ADUser internally and returns some of those objects, the output will also be formatted as a list. Piping the output to Format-Table before returning it does not satisfy my requirements, because the output will then not be treated as separate objects in a pipeline.

Example code:

When a divide-and-conquer recursive function doesn't yield runtimes low enough, which other improvements could be done?

Let's say, for example, this power function taken from here:

I've created a simple VBA interface to connect Excel to a MySQL DB. The VBA part acts as a preview of data for the user to choose what item he wants to import to the Excel sheet.

Until now I've work with a very complete set of data, but I got to a Table which (because of the nature of the items) some fields are NULL.

Now every time I try to check the values in the VBA I get the Run-time error 13 Type mismatch in the listview component. At first I though it was a field with DECIMAL typing, but after changing it to a DOUBLE (for testing) the problem persisted, and it was until I notice that if only checks columns with no NULL value, the problem disappears. Off course I can't omit this values.

I tried some .Tostring functions but with no success. And I failed to implement a IF to check for NULL in the obj.

This is my code:

I am programming in Python 3.8 with Tensorflow installed along with my natural language processing project. When I want to begin the training phase, I get this message right before I begin...

I have about a half million records that look somewhat like this:

I did some research and found this: Setting a fixed FPS in Pygame, Python 3 and this: pygame clock.tick() vs framerate in game main loop. It is similar to what I am asking.

So the clock.tick(FPS) caps the program to run at that FPS. The reason you do this is so you can control the FPS of the program and it makes it easier for time stuff like waits.

But how can I unlimited FPS and still control my FPS for time stuff like waits? From my understanding, this is not possible, due to the fact that clock.tick(FPS) caps the FPS and while not adding it in means unlimited FPS but you not being able to control the FPS.

So it seems to be a question of weather to cap you FPS for control or have your program run as fast as possible, but without control.

In conclusion, what I am asking is four questions;

1. Pros and cons of capping your FPS
2. Pros and cons of not capping your FPS and going on with the natural FPS of your program
3. Is it possible to have unlimited FPS and still control my FPS for time stuff like waits?
4. If so, how?

I'm trying to create a pseudo-random generator API, but numbers generated by xorshift have unrandom nature. You can see the algorithm and tests here:

I posted a similar question a week ago but I failed to identify the real problem. Therefore, the question was far from being correct.

Now, I clearly now what is going on but I cannot understand why it is happening. I also reviewed similar problems related with the same error but the solutions for these problems were not applicable to my case.

I am plotting the frequency distribution of a variable during the fieldwork progress of a survey. Therefore, it shows how the proportion of that variables has changed through time.

So, I have a variable (Startday) that tells which day the respondent took the survey, if he/she did not then it is NA. Then, I have the typical variables like sex or marital status.

This is the code to plot such graph

I am trying to insert a row into database provided that - number of rows satisfying some condition already in the table is less than certain threshold, say 10. For example, in below model, I don't want to have a project to have more than 10 users; so count(projectId) should be less than 10:
