Sending HoloLens 2 video stream through Roboflow API
Hello everyone,
I’m currently working on a mixed reality project for the HoloLens 2, which involves the use of a computer vision model for the recognition of some shop-floor equipment and parts. My team has trained this model in Roboflow, using the data we’ve collected in a factory.
However, we’re not sure how to integrate this model to the HoloLens. We thought it could be a good idea to access the HoloLens’ video stream in order to send it to the CV model through the Roboflow API, and get the result back, in runtime. So we’re looking at Microsoft’s CV samples for the HoloLens 2, which includes a “StreamRecorder” sample. However, this sample saves the stream in a raw format, which would need to be converted before sending it to the CV model.
We’re actually not even sure if using this sample as a basis is the best way to do what we want, so we’re a bit lost at the moment. Has anyone here tried accessing the Roboflow API from a HoloLens 2? How would be the best way to go about it?
Thanks in advance.

How we can filter all the tasks from all the Plans based on the assgined user
We have a Teams which contain around 40++ planner plans. The managers are facing troubles when they want to see all the tasks from all the planner plans assigned to certain user. Currently to do this, they need to go to each individual plan and do the filter, is there any built-in or using sharepoint web parts to be able to filter all the tasks from different plans based on the assigned to user?
Thanks

Updates from the 162.3 release of SqlPackage and the DacFx ecosystem
The quarterly release cadence for SqlPackage and DacFx continues with the 162.3.563 release on June 6, 2024. The most notable change in this version is the preview release of a target platform for Fabric mirrored SQL databases. The 162.3.563 release also includes fixes related to script parsing (ScriptDOM) and deployments. Read more about the fixes in the SqlPackage release notes.
Target platforms in SQL projects
SQL projects are a logical framework around your database code and this sets the foundation for two development capabilities:
Build-time validation of references between objects and the syntax against a specific version of SQL
Deployment of the build artifact to new or existing databases
When a SQL project is built, the relationships between objects contained in the project files are validated. For example, the columns or tables referenced in a view definition must exist in the SQL project.
SQL project files in VS Code
Additionally, a SQL project contains a property called the “target platform” in the DSP element of the .sqlproj file. This setting is used during the build process to validate that the functions and T-SQL syntax is supported in the specified version of SQL. For example, the JSON functions added in SQL Server 2022 cannot be used in a SQL project set to the SQL Server 2017 (Sql140DatabaseSchemaProvider) target platform.
Mirroring your SQL database to Microsoft Fabric provides a streamlined experience to avoid complex ETL (Extract Transform Load) and integrate existing your Azure SQL Database estate with the rest of your data in Microsoft Fabric. In the new target platform for “Fabric mirrored SQL database (preview)” (SqlDbFabricDatabaseSchemaProvider) added in DacFx 162.3.563, the tables in the SQL project are validated for compatibility with mirroring to Microsoft Fabric. Having a target platform for a mirrored SQL database means that you can develop your Azure SQL application with confidence that the application’s data will be available for analytics with minimal additional effort.
Diagram of Fabric Database Mirroring for Azure SQL Database
The target platform is available immediately for use with SDK-style projects with the Microsoft.Build.Sql project SDK version 0.1.19-preview. Your existing SDK-style SQL projects can be moved from the Azure SQL Database target platform to the Fabric mirrored SQL database (preview) target platform by updating the version of the Sdk to 0.1.19-preview (line 3 below) and the DSP (target platform) to SqlDbFabricDatabaseSchemaProvider (line 7 below). For a walkthrough of mirroring your Azure SQL Database to Microsoft Fabric, check out the tutorial.
The “Fabric mirrored SQL database (preview)” target platform will be available directly in the SQL projects extension for VS Code and Azure Data Studio as well as Visual Studio in the upcoming months. In the meantime, SQL projects can be built and deployed with the new target platform from the command line with dotnet build and SqlPackage.
SqlPackage and SQL projects on arm64
GitHub recently announced arm64 actions runners with the initial availability in public preview of images built on Ubuntu 22.04. Whether you’re using the recently launched arm64 runners, an Apple M-series workstation, or one of the arm-powered Surface devices the base requirements for working with SqlPackage and SDK-style SQL projects remain the same – the .NET SDK must be installed. The current Ubuntu 22.04 arm64 preview image includes the .NET SDK.
With the .NET SDK installed in an arm64 environment such as the GitHub actions arm64 runners, your SQL development workflow can leverage the same commands as x64 environments. Dotnet build is still used to create a dacpac from a SQL project, but you may need to install SqlPackage as a dotnet tool to perform additional actions:
dotnet install -g microsoft.sqlpackage
Once SqlPackage is installed it can be used as usual, including deploying (publish) a dacpac to update the schema a database or to extract the objects in a database out to files.
# publish
sqlpackage /Action:Publish /SourceFile:bin/Debug/AdventureWorks.dacpac /TargetConnectionString:<YourConnectionString>
# extract
sqlpackage /Action:Extract /SourceConnectionString:<YourConnectionString> /TargetFile:AdventureWorks /p:ExtractTarget=SchemaObjectType
For developers interested in continuing to use the original SQL projects in Visual Studio, we also note that SQL Server Data Tools (SSDT) has been released for Visual Studio on arm64.
.gitignore with SQL projects
You may recall about a year ago we introduced project templates for quickly starting a new SQL project from the command line. Earlier this year an option was added to the templates (-g) which includes a default gitignore file with a new SQL project. With a .gitignore file you can avoid accidentally checking cached binaries in the bin and obj folders into source control and minimize noise in your source control history.
Installing the SQL project templates and creating a new SQL project with the Fabric mirrored SQL database (preview) target platform and a gitignore file is completed with these two commands:
dotnet new install Microsoft.Build.Sql.Templates
dotnet new sqlproj -n “AdventureWorksLT” -tp “SqlDbFabric” -g
Ways to get involved
In early 2024, we added preview releases of SqlPackage to the dotnet tool feed, such that not only do you have early access to DacFx changes but you can directly test SqlPackage as well. Eagle-eyed readers will notice that the last preview release prior to the full release only differs by a single patch build. Get the quick instructions on installing and updating the preview releases in the SqlPackage documentation.
All are welcome to stop by the GitHub repository to provide feedback, whether it is bug reports, questions, or enhancement suggestions. Here are a few recent feature suggestions you might want to weigh in on:

Plotting the Evolution of Spatially Localized Initial Conditions for Discrete Klein-Gordon Equation
Ιn continuation of the study with which I have been fascinated Numerical Simulation of a Damped, Driven Nonlinear Wave System with Spatially Extended Initial Conditions
Now we examine the role of damping in the structure of the branches of equilibrium points. In this study, we consider localized initial conditions of the form:
where is the distance between the nodes, and is the amplitude. We assume zero initial velocity
We also note that if we consider an infinite chain, the initial conditions $(1)$ satisfy the Dirichlet boundary conditions only asymptotically. However, since the smallest half-length of the chain has been set to $ L/2 = 100$, the error is of the order of $ 10^{-44} $, which does not affect numerical computations.
The figure shows the dynamics of the initial condition (1) for parameters: and . In the first image of Figure, we observe the profile of the initial condition.
The subsequent images show the dynamics of the system for different values of the damping force . For , the convergence takes place at the equilibrium point which is the basic state.

Now we examine the role of damping in the structure of the branches of equilibrium points. In this study, we consider localized initial conditions of the form:
where is the distance between the nodes, and is the amplitude. We assume zero initial velocity
We also note that if we consider an infinite chain, the initial conditions $(1)$ satisfy the Dirichlet boundary conditions only asymptotically. However, since the smallest half-length of the chain has been set to $ L/2 = 100$, the error is of the order of $ 10^{-44} $, which does not affect numerical computations.
The figure shows the dynamics of the initial condition (1) for parameters: and . In the first image of Figure, we observe the profile of the initial condition.
The subsequent images show the dynamics of the system for different values of the damping force . For , the convergence takes place at the equilibrium point which is the basic state.

BLOG: What deprecation means in practical terms for Windows and Windows Server
What deprecation means in practical terms?!
An important and careful read every time.
Each release of Windows / Windows Server doesn’t only come with enhanced features and fixes, but also deprecation notices you have to consider.
What’s deprecation?
It’s a tag on a role or feature that longer under development.
And it marks the start of getting stale or even being removed completely from the OS. Most of the time all deprecated features will become optional features, first.
Karl, how do you deal with deprecated features?
I personally try to consult customers to remove inbox Optional Features. In this case they may not accidently use these, or otherwise notice they are in use when missing in the first place.
Feature removals are quite rare but that’s exactly why you should really consider watching the space of deprecation notices.
Are deprecated features generally removed?
Clear no. But there’s a risk of that. You should not build a business around or on deprecated features.
Removals can occour quickly, usually rather planned, when a security concern arises and no fix can be made, or a feature, by telemetry is rarely used in the first place.
Are deprecated features supported?
It depends. Every feature in-box is under the support policy of the product. So far the rules.
Do not expect up to par Microsoft support for deprecated features. Same as with OS versions outside the mainstream support (extended support), like Windows Server 2016 / 2019, both widely spread, at the time of writing.
Keep an eye on the product support matrix and the support conditions. Microsoft used to call these Lifecycle Policies, of each product.
Also other (Microsoft) products you are running on top of an OS. Speaking for the OS, the Microsoft support team might advice you to move on when for break / fix situation, no remediation can be found, and the product is deprecated or outside mainstream support.

Windows 11 Memory Compression
I am currently running Windows 11 Professional version 23H2 (OS Build 22631.3593).
I am looking as Task Manager, Memory to see the following:
As you can see, my workstation has 192GB of total RAM. Only 20GB is in use with plenty available. I am noticing that Windows has decided to compress memory even though I have plenty available. On-the-fly compression has a cost. Why would Windows randomly decide to waste processing time compressing when it is absolutely unnecessary?

Pivot tables, more than one person/unit assigned to a task.
Hi, I have the example table below. How do I create a pivot table that lists the tasks each Unit is responsible for? I would like it to look like:
Policy Unit
Task 1
Task 8
Task 9
Compliance Unit
Task 2
Task 3
Task 5
Task 7 etc…
Basically wondering how can I combine Unit and Unit2 to use in my pivot table. Or how do I create a pivot table that would list tasks by each owner, John is responsible for Task 1, and 9.
I am stuck when a task is completed by more than one Unit or person?

Is there a way to use existing c++ interfaces wrapped in differing namespaces in Stateflow without redefining them to C-Style enums?
*Problem Description:*
Given a large project with interfaces defined in the form:
namespace ns1
{
class MyClass
{
public:
enum myEnum : int8
{
FOO = 0,
BAR = 1,
FOOBAR = 2
};
myEnum m_myEnum;
}
}
namespace ns2
{
class MyOtherClass
{
enum myOtherEnum : int8
{
FOO = 0,
BAR = 1,
FOOBAR = 2
};
myOtherEnum m_myOtherEnum;
}
}
Within C++, the value of the first enum could be accessed using ns1::MyClass::myEnum. In order to write on variables using these interfaces from a Stateflow generated C-File, I only came up with one solution so far: to have the Code Generator redefine both interfaces in C-Style, based on the values entered within Stateflow:
typedef enum
{
NS2_MYCLASS_MY_ENUM_FOO = 0,
NS2_MYCLASS_MY_ENUM_BAR = 1,
NS2_MYCLASS_MY_ENUM_FOOBAR = 2,
} MY_ENUM
typedef enum
{
NS2_MYOTHERCLASS_MY_OTHER_ENUM_FOO = 0,
NS2_MYOTHERCLASS_MY_OTHER_ENUM_BAR = 1,
NS2_MYOTHERCLASS_MY_OTHER_ENUM_FOOBAR = 2,
} MY_OTHER_ENUM
To get these values back on variables, defined in the form of the original enums, there have to be static casts implemented like e.g.
instanceOfMyClass.m_myEnum = static_cast<ns1::MyClass::myEnum>(MY_ENUM)
instanceOfMyOtherClass.m_myOtherEnum = static_cast<ns2::MyOtherClass::myOtherEnum>(MY_OTHER_ENUM)
The disadvantages are:
* redefinition is extra work, prone to errors and a lot of work to keep in sync
* static casting is dangerous, especially, when e.g. the order of the values within the enumeration changes
* the principle of single source of truth is violated which leads to these disadvantages
*Question:*
* Is there a way to directly use the original, C++-Style enums without recreating them and having all the stated disadvantages?
* I’m thinking about a solution where I can enter the names and paths of the original interfaces directly within StateFlow and generating C++ code that is therefore already integrated – without any wrapping and extra, error prone work.*Problem Description:*

Create ‘siteviewer’ object without displaying it?
Hello,
Is there a way to create a ‘siteviewer’ object without actually displaying it? I know there’s the option of running the command siteviewer(‘Visible’,’off’), but this command does display the object, even if it closes it inmediataely after. Is there some way to just create the object and have no display of it at all?
Thanks in advance,

Turn Off the “Try Copilot Pro” Ad at the top of Word
I have removed Copilot completely from my PC through the registry settings. That worked and I don’t see Copilot anywhere now; however, I still see this little “Try Copilot Pro” at the top of my Word documents. I realize Microsoft has long had frequent problems with the whole “No Means No” thing and likes to go deaf when it comes to their users and their preferences, but how do I disable this? I got rid of Copilot for a reason and don’t want it constantly shoved in my face.

Join us for a 45-minute session on June 19, 2024 on how to use the recently launched Partner-led Copilot Immersion Experience, providing partners the ability to demo and help customers with hands-on experiences.
In this session, we will walk you through each of the assets to drive adoption of Copilot for Microsoft 365 by role/persona and provide you guidance on the best way to utilize and demo with your customers–showcasing how Copilot can help businesses solve common problems and achieve more.

Our guidance is to invite an entire department to a training session where you can spend 15 minutes showing what’s possible with Copilot using click-thru demos, 15 minutes for customers to try themselves with dummy content, and 15 minutes for customers to progress their own projects by bringing their own files.

AVD Authentication Type
I have just completed a setup with Azure AVD for remote desktop and an application and I’d like to know if there’s a way to change the authentication or login type when using Azure AVD. Or if a prompt can be enabled in the settings of AVD. We only have 10 users spread across 2 AVD VMs. I have a Windows Server AD virtual machine running in my Azure tenant on the same vnet as the AVD setup. These were domain joined using the AVD deployment process and assigned to a specific OU in my domain. My Active Directory is using .local usernames and my Azure tenant does have an authenticated and valid domain for users and email. I did expand my AD to include the UPN alternative suffixes and I’ve adjusted the accounts so that my Office365 tenant logins match the AD logins. However, when I connect to my AVD workspace using Remote Desktop App, I cannot connect and it sends an error of 0x83886163 during the configuring gateway process. The Session Desktop and my app is published properly to the Remote Desktop App, but I simply cannot connect.
Basically, is it possible to adjust AVD to prompt for a username once I click on the Session Desktop or my published application? I did locate some authentication settings in the RDP properties and connection information of the host pool.
Thanks for any suggestions or input.
