How are you creating space in your organizations for 11 minutes a day of AI experimentation?
In a recent article on the Microsoft Work Lab site (link in comments) on organizational adoption, one best practice is about training. However, training or the delivery of the instructional content is one piece. There is always the challenge of transfer, putting it into practice. One point in the article stood out:
“Like any new routine, building the Copilot habit takes time. Our internal research has found that a time savings of just 11 minutes a day is all it takes for users to see the value from Copilot.”
In addition to formal training sessions, how are you creating space for your people to practice to build a habit and see a time savings of 11 minutes a day?

Video transcript:
-Does it make sense to run your Linux workloads on Azure, and how serious is Microsoft about Linux and open source software? Well, today, I’ll answer those questions and more. First, Microsoft itself relies on Linux for some of its most popular cloud services.
-For example, Azure OpenAI Service, Azure Kubernetes Service , the App Service, Cosmos DB, Azure Database for PostgreSQL and more all run on Linux.
-And it may also surprise you to know that Microsoft is one of the largest contributors to the open source community and has been for more than a decade. In fact, many of the Linux and OSS features and components across the platform stack that you use every day, have been built by and are maintained by people at Microsoft.
-From Linux kernel releases for reliability and security, to Systemd, which is used to manage the Linux boot experience, KVM, or Kernel-based Virtual Machine, an open source virtualization technology built into Linux since 2007, and related to that, the QEMU machine emulator for full system and user mode emulation. At the data layer, the Data Plane Development Kit, or DPDK, provides libraries and network drivers for faster packet processing and for networking there’s the Common Internet File System, or CIFS, network file-sharing protocol.
-Then, moving up the stack, there’s GNOME with its improvements to the graphical user interface, as well as Mesa3D, used for gaming and 3D implementations like OpenGL, Vulkan, and others. It also may surprise you that Microsoft contributes to and maintains its own distro. The Azure Linux OS is an open source distribution that is used broadly across a number of Microsoft services from Microsoft 365 to the Xbox services, Minecraft’s global creativity platform and the Windows Subsystem for Linux.
-Then there’s also Linux-based open source semantic kernel SDK, developed and contributed by Microsoft, that lets you easily build agents that can call your existing code. And you can use it with models from Open AI, Hugging Face and more. Additionally, Microsoft contributes to Kubernetes, which provides the foundation for container orchestration and is key to cloud-native app architectures.
-And of course, Microsoft runs GitHub, the largest hosting platform for open source projects with more than 100 million developers. These are just a few notable examples of Microsoft’s role as a dedicated and active community member helping to drive the open source Linux platform forward. Now Azure itself, is designed to be an open platform, freeing you up to use the tools and technologies of your choice. In fact, the vast majority of compute workloads, virtual machines and containers run Linux. It’s on more than 60% of all active customer compute cores.
-And today, there’s really nothing to hold you back from building your entire app in Azure, using open source technologies, and I’ll prove it to you using only Linux and open source services. This is actually the machine of one of our Microsoft engineers and Microsoft has thousands of employees that use Linux as their primary OS. It’s a workplace-provisioned Linux machine running Ubuntu.
-And when I sign into Intune, you can see it’s a fully enrolled device and as part of the Microsoft corporate network, it’s met the device and security requirements for Microsoft IT. We’ve started building a generative AI app using Azure OpenAI service and we’re prompting it to write a Python script to create safe passwords with a minimum length and special characters.
-So we can see it’s working pretty well, and so the next thing we want to do is to make sure that the app scales. So, first, we’ll run a load test for the app to simulate 50 simultaneous users. This will help us see how well it performs with the current assigned compute using containers running Linux.
-And a test like this normally takes a few minutes to run, so we’ll speed things up a bit. And you can see that as users and requests jump up, the response time is also increasing and we’re getting errors based on the allocated compute. There aren’t enough pods to handle the heavy load. And we can jump into the open source Grafana dashboard, which is an Azure-managed service, and we’ll see that the CPU throttling is maxed out at 100%, so let’s fix that.
-So here, we’re using a GitHub Codespaces cloud-hosted VM as a dev environment as you can see in the lower left corner of the screen, and this was spun up directly through a GitHub code repo. It’s already got Visual Studio Code running locally. Now, we’ll highlight the resources for this app with memory and CPU.
-And we’ll use GitHub Copilot to set the CPU request to 1 CPU and set limits to 2 CPUs, and it makes the necessary changes. Now we’ll add another prompt that’s a bit longer to set up autoscaling with the right min/max number of replicas and how to scale down. And it creates the code for me automatically.
-Now we’ll add another prompt with instructions for minimum and maximum nodes in a Bicep template, and by the way, I could have used any infrastructure as code like Terraform for example. And from here, we can even use GitHub Copilot to create a multistage Docker file with the rest of what we need, before we commit changes. Now we need to perform a series of commits for all the changes that were just made and run the docker file and the Bicep template for the deployment, which I’ve skipped past to save time. So now, going back to our app, you’ll see it’s completely updated, and everything is up and running with the configuration changes.
-So, let’s re-run the load test, and again, that’s going to take a few moments to run. This time, we’ll head directly in Grafana and on the right of the CPU usage graph, you’ll see that all of our pods are distributing the load, and by changing the view to show the last five minutes, we get a better view across our containers as they handle the load test.
-So our app is no longer getting throttled by resource constraints and we’re ready to handle a lot more requests. And again, everything you just saw ran Linux and open source. So now let’s get into your options for deploying, managing, and extending your Linux workloads on Azure.
-First, almost every Linux distribution runs on Azure, so you have plenty of choice. There are hundreds of Linux offerings in the marketplace, and you can bring your own image or distribution as well. You can also see that in the community gallery there are hundreds of image options with about every flavor of Linux you can imagine.
-Azure’s service platform and its hypervisor layer is also fully-optimized for Linux to ensure peak performance and security. There are free and low cost options to get started in Azure that you can use with Linux virtual machines, containers, or other services. And if you’re part of a startup, the founders hub program can provide up to $150,000 to apply toward Azure services, including OpenAI and popular Linux distros.
-Additionally, as you create your VMs, with Azure Hybrid Benefit, you can bring your own Red Hat or SUSE Linux subscriptions to Azure and realize cost savings of up to 76% when combined with reserved instances. You can deploy, manage, and scale Linux cloud apps of any size, where you have a number of options. In fact, Microsoft has close engineering partnerships with SUSE, Ubuntu and Red Hat, three of the most popular distros. Now for Red Hat specifically, the depth of partnership, integration and support is unparalleled compared to other Cloud providers. For example if you have an issue, as you work with your support team both Azure and Red Hat’s support engineers can work together with your approval.
-And in fact, these engineers are often co-located, and their customer service systems are integrated to triage issues in the least amount of time by enabling them to collaborate efficiently on your case as they troubleshoot the problem and work towards a solution. And we also uniquely run a number of managed Red Hat services in Azure with direct integration built in.
-For enterprise workloads, you can use Ansible to automate the configuration and deployment of your Linux VMs and applications on Azure, or JBoss EAP to run Java Enterprise Edition apps on Linux VMs or containers. So now let’s move onto your open source options for compute, spanning multiple infrastructure architectures and using your preferred data backend services. Azure Container Instances lets you quickly deploy and run container apps without managing servers. And if VM or physical servers are your thing, of course you can run containers on those as well, with unified management and orchestration. Additionally, Azure Kubernetes Service, or AKS, lets you run containerized applications across multiple nodes.
-And there are also hybrid and multicloud solutions with AKS running on Azure Stack HCI, as well as Arc enabled Kubernetes which extends unified management and governance capabilities to your Kubernetes clusters wherever you need them. Then, for your data backend, you can use open source options, like PostgreSQL, MySQL, Cassandra, Redis, and others. As you’ve seen, there’s literally all the building blocks for developing, deploying and managing your Linux workloads.
-And once you are in Azure, you can extend and modernize your app experiences with some of world’s most robust AI solutions running on Azure’s supercomputer infrastructure and integrated platform. For example, for your AI workloads, you can use Azure Machine Learning to build, train, and deploy machine learning models using Linux-based compute clusters and environments.
-And use Azure AI services to augment your apps with vector search, AI vision, AI speech, AI translation, Document Intelligence read OCR at scale, and more. There are also significant security advantages for your Linux workloads. Azure processes ensure supply chain security, and all services are built with security in mind from the kernel up. Microsoft also employs more than 10,000 security specialists, with detection and response solutions powered by AI, and backed by the largest compliance portfolio in the industry.
-For example, Microsoft Defender for Cloud brings advanced threat protection, security recommendations, and real-time monitoring to your Linux and hybrid workloads. If you’re in a highly regulated industry, Microsoft is also a leader in confidential computing for protecting sensitive data while in use with Confidential Computing, partnering with AMD, Intel, and NVIDIA for hardware-based isolation with virtual machines and containers.
-So, to answer the question I posed earlier, hopefully, I’ve convinced you that it’s a no-brainer to run your Linux workloads on Azure. To get started with Linux on Azure, check out azure.com/linux. Subscribe to Microsoft Mechanics if you haven’t already, and thanks for watching.

Error while calling a Keras Model from Matlab
Basically, I have regression neural network saved in .H5 format. I want to use the NN model’s prediction in my simulink model. I am trying to call the python where the NN model is imported using Keras.load_model. When I call the python with NN model imported I am getting an error but if I call it without the NN model its working fine.

function y = fcn(in1,in2)
y = 0; % Has to be preassigned, otherwise Simulink throws an error
coder.extrinsic(‘py.final10.test’) % Python functions have to be run extrinsically, meaning no C code generated
y = double(py.final10.test(in1,in2));

Convert Simulink to m file
A lot (or most or all?) of the configuration of a simulink file can be done programmatically. Is there a way to convert an existing simulink slx file into an m file that contains all (important) steps necessary to build the slx file? I do not care so much about the visual documentation that the simulink file inherently comes with (routing of signals, position of blocks). So, an m file containing all commands to build an slx file is enough for me. The advantage would be that one can more easily track the text-based m file in programs like git (I am aware that there are ways to track simulink files as well but I prefer text-based files).A lot (or most or all?) of the configuration of a simulink file can be done programmatically.

Acquire data from a python device in continuous (synchronuous) mode on a PC with Matlab installed.
Hi.
I’ve a raspberry device on wich I’ve installed Python.
My raspberry reads in realtime data from an MLX 90640 IR Thermal Camera and write it on a txt file.
If I copy this txt file on a PC with Matlab installed, I can read thermal data and process it in Matlab to produce, i.e., an heatmap.
This process, however, is an asynchronous process since I must :
acquire thermal data on raspberry
stop the acquisition
copy the data on the PC with Matlab installed
run the matlab application to view the heatmap
Obviuosly I’d like to trasforf this process from asynchronous to synchronous so that I can view real time data acquired from raspberry-Python device on Matlab in the same time that they are acquired and in contunuous mode.
The question is: is there any way to do this? And if yes, how?
Any idea?

Question on difference PWA instances
Hi,
I am researching how to setup permissions in PWA. I’m a SharePoint Administrator, so I understand those permissions and I see there is a way to change the permission management between SharePoint Permissions Mode and Project Permissions Mode.
My main question is, do these permissions affect any PWA that others might have or is it only my instance of PWA? My manager wants a more fine-grained permission set, and it looks like it is best to use the Project Permissions Mode for that. Can I change my PWA and not affect any others as a way to test these permissions?
Appreciate any help!
Thanks,
Monty

Need Help Updating Large Data Spreadsheet
Hi,
I need help on how to compare two list. The Blue Column (MMO) is the Master List, and I used XLOOKUP command (and even tried nesting them) to compare two columns. Due to potential spelling errors and/or missing word(s) like shown in the picture (green highlight) it’s not picked up by the exact search so I also used small, larger, wildcard categories as well. My issue now is I can’t individually check down the column because there are too much, 4000 names down the list, and it will take too much time. How do I go about checking them without resorting to brute forcing myself? I reckon it would require chains or nesting commands, but I can’t solve it.
Thank you in advance for help, and have a good day!
EDIT: Can share the excel file via Onedrive if needed.

Attack Simulation Training & Manager Notifications
New to Attack Sim, but have a question about notifications, specifically how to notify a user’s manager if they fail a phishing sim and if they haven’t completed the enrolled training. Does anyone know if this is possible? Anyone doing this?

Disabled web push notifications on Android of a deployed Web link
Hi,
We are using Microsoft Intune to manage our company devices. We have enabled web push notifications on one of our websites, and it works correctly on Windows desktops as well as on Android and iOS devices.
However, once we deploy the website as a web app link through Intune on Android, the web push feature no longer works (even though we enabled push notifications on the App deployed by Intune on the device for the web link). Additionally, even when connecting to the website directly through Chrome web push notifications do not work.
It seems that the browser might not allow enabling the web push service for our website when it’s installed through Intune. We know it’s not a device or browser issue because web push notifications work correctly if we connect to another test website that’s not deployed through Intune.
Is there any configuration or setting we need to do on Intune to enable web push notifications on our Android devices?
Thank you in advance for any help,
Charles
