Touchpad Only Works with Bluetooth Device
I’ve been experiencing a strange issue with my laptop’s touchpad on Windows 11. The touchpad only works when I have a Bluetooth device connected, such as my headphones or a wireless mouse. As soon as I disconnect the Bluetooth device, the touchpad becomes unresponsive and stops working.
I’ve tried restarting the laptop, updating the touchpad drivers, and even disabling and re-enabling the touchpad in the device settings, and I’ve also checked the BIOS settings and made sure that the touchpad is enabled, but the issue persists.
I need your help.

Market Place application (solution template)
I try to create a Azure Market Place application (solution template) and try to test the solution near my Subscription with ARM template deployment :
1. When I used resources i was able to createselect vnet and create subnets inside if the virtual network was under the same RG of the main ARM.
2. the issue started when i tried to select existing vnet on a different RG (that required me to change the resources to be “Microsoft.Resources/deployments” instead of resources)
I modified the deployment to get a new parameter of the vnet RG and passed it to the deployment and now I’m receiving a validation error when I try to deploy (using custom deployment from a template in the portal).
the error received from the validation step is:
Deployment template validation failed: ‘The resource ‘Microsoft.Network/virtualNetworks/walkme-test1/subnets/walkme-in’ is not defined in the template. Please see https://aka.ms/arm-syntax for usage details.’. (Code: InvalidTemplate)

Security Report on SharePoint – Fastest Way
What is the fastest way to run a report on Sharepoint permissions – Graph API, Pnp, MS Powershell, REST API?
I need to get a report back for a list of users on their access on every site, list/Library, and file/item level in the tenant, with 10K+ sites, 10K+ OneDrives.
I see there are many 3rd party tools available like Avepoint, Sharegate, etc. and I used one of these tools to run a report for a single user, just to return Sites (no item level or Lists/Library) and its taken 3 hours and report is still running.
And we have to consider any throttling MS will do with long running queries or number of queries per second.
Just wondering what people do these situations?
PS: I realise having large number of sites and data is an issue, and with inheritance broken doesn’t help either but trying to understand what people do in similar situation.

Analyzing data sets that are not statistically significant
I have the attached data. Those are the testing results of fibre reinforced cement mortars. First column indicates lengths of fibre used and the second column indicates the volume ratios. Third coloumn I have porosity data. I analysed all the data statistically, but no combination found statistically significant (Based on P-vale, correlation coefficient and R-squared). Sometimes may be due to only three data points for each combination (For an instance at 6 mm length, how volume ratios affect porosity have three data points and etc.)So I would kindly would like to know wehther nay other machine learning or techniques are available to interpret these data interestingly and effectively to the scintific community? Becuase, as this, I have 4 more test paramters (not only porosity) and four fibre types as well.

Struggling with FMU Exporting Simscape components, they work fine in simscape, but when I export to FMU and resimulate to test, the model fails.
I’m currently making a simple physical system (Gas, Mechanical in Simscape, consisting of a reservoir, two Compressors (G) (with an ideal angular velocity source), a Pipe (G) with a controlled heat flow source providing cooling, and a reservoir downstream to sink to. It’s a very simple system and more just being used as a high level model to test out FMU exports. None of the components are changed from default except for the Reservoirs, Heat Flow Sources providing some BCs, and the Compressor has Analytical parameterization and is being set to a specific design point based on a compressor data set that’s being used.
The model works fine in Simscape, I have a controller that admittedly takes a while to reach steady state but aside from that I’ve not seen any issues. When I export this model as an FMU, the model seems to break. I use the inputs that I’ve had before but they seem to break the model and give the following error:

One theory I have is that because I’ve used Analytical mode as opposed to Tabulated parameterization, the compressor is struggling. This would explain why the FMU does seem to work after I increase the Speed, but the results are inaccurate (going from 0.3 kg/s to 14.3, and going from 101.3kPa to 10*4kPa)

Component:Simulink | Category:Model
An error occurred during simulation and the simulation was terminated
Caused by:
Error in supplied FMU: An error occurred in function ‘fmi2DoStep’ for block ‘FMU_Testbed/FMU’ during simulation. For more information, see the FMU troubleshooting documentation.
Component:Simulink | Category:Block error
One theory I have is that because I’ve used Analytical mode as opposed to Tabulated parameterization, the compressor is struggling. This would explain why the FMU does seem to work after I increase the Speed, but the results are inaccurate (going from 0.3 kg/s to 14.3, and going from 101.3kPa to 10*4kPa)
Original Simscape Model:
FMU Block test (Constant inputs from Simscape were turned into inports and I’ve just been testing the FMU to see if they work):
Produces error mentioned earlier
FMU Block test, increased Speed:
Any help here would be appreciated compressor (g), matlab, simscape, fluids, simulink, fmu, export MATLAB Answers — New Questions
how to have an optional bus signal inside a subsystem?
Hello,
I want to create a subsystem that I can reuse in different scenarios (maybe as subsystem reference, not really important).
I would like to pass the signal to this subsystem as a virtual bus.
Inside the subsystem I use the in bus element to get the signals I need from the bus.
Now, since I use this subsystem in different models/configurations there are signals that sometimes are present and sometimes are not present inside the virtual bus, like in the example image below: signal3 is not present inside the bus and so simulink throws the error:
Selected signal ‘signal3’ in the Bus Element Inport block ‘untitledeee/Subsystem1/In Bus Element1’ cannot be found in the input bus signal.
I would like to use a default value when I recognize that the input is missing. In matlab functions you can easily do this with optional arguments (link: arguments – defaultValue).
My question is: there is a way to replicate the optional arguments of matlab functions inside a subsystem/reference subsystem/model reference?
There is some suggested workaround?Hello,

Report Delegated Permission Assignments for Users and Apps
This article describes how to use the Microsoft Graph PowerShell SDK to report delegated permission assignments to user accounts and apps. Like in other parts of Microsoft 365, the tendency exists to accrue delegated permissions for both user accounts and apps over time. There’s nothing wrong with having delegated permissions in place, if they are appropriate and needed – and that’s why we report their existence.

Exceptions for Security recommendations – CVE Weakness
Hi All,
We have a critical CVE (Defender Portal) on a system that is no longer in operation. Now I want the CVE to no longer appear in the dashboard under “Weaknesses”.
So I have manually tagged the system as “Decommissioned” and built a device group “Decommissioned” based on the tag.
As far as I know, you can only set the “Exceptions” to “Security Recommendations” globally or on Device Groups.
So I set an exception on the “Recommendation” related to the device group.
However, the vulnerability is still displayed under “Weaknesses”.
My hope was that the vulnerability would be removed from the overview so that I would see fewer false positives.
My guess is that since the Security Recommendations contain a total of 55 CVEs, the process is not working as expected.
How do you handle Exceptions in the Dashboard/Overview?
Thanks for the help.

Lists – affected item – custom permissions
Hello,
If the tasks in the “planner” could be much more customizable, I’d use “planner”, however, the tasks are too rigid, not customizable enough, so I’m forced to use lists.
But how can I reproduce the native behavior of “planner”: have a global list, with members only see the tasks to which they are assigned?
I see two approaches.
1) Define a master list containing a “team” column, define a list in each team, then synchronize the items in each list, update them when modified, etc. with PowerAutomate.
Or :
2) Define lists in each team and build a global list from all items in each list.
Which is the better option? Is there another way of doing this?
