Simulink migration from ros to ros 2
Hi all,
I have a simulink project that generated a code for ROS.
Due to migration to ROS 2, this code is no longer adequate and I would like to obtaine the ROS 2 generated code.
Any orientation as to where to find an answer for this would be more than welcome.
Thanks in advance.Hi all,

How to call Matlab script from Labview using the Labview “Call Matlab Function” function
mycirclescript.m contains the following:
"r = 3
A = pi * r^2"
Labview program is simply the following:
"Open Matlab Session" with path to Release Name ("R2019b") in string constant.
followed by the "Call Matlab Session" function with .m file path selected with a control.
followed by the "Close Matlab Session"
All three functions have "Session Out" connected to "Session In" and "Error Out" connected to "Error In", with an indicator for Error Out
on the Close Matlab Session function.
This is the simplest possible script and I don’t see Matlab open and the only thing returned
is the following error below"

Why do we use ifft instead of fft when looking at the spectrum of a sech pulse (uu) in this code?
In the code below, temp = fftshift(ifft(uu)) is used to view the sech pulse in the spectrum. However, since ifft is a function that transforms from the frequency domain to the time domain, wouldn’t temp = fftshift(fft(uu))) be correct? Why does the book do it this way?

Public Preview: Upgrade Policies for Virtual Machine Scale Sets with Flexible Orchestration
Status: In Preview
The upgrade policy of a Virtual Machine Scale Set determines how virtual machines can be brought up to date with the latest scale set model. Before today, upgrade policies were available for Virtual Machine Scale Sets with Uniform Orchestration. Now the same upgrade policies available for Uniform Orchestration are available for Virtual Machine Scale Sets with Flexible Orchestration.
The upgrade policies available for Virtual Machine Scale Sets are Automatic, Manual and Rolling. Additionally, if using a Rolling upgrade policy, you can choose to enable MaxSurge to create new instances with the updated scale set model to replace virtual machines using the old model.
Automatic upgrade policy
With an automatic upgrade policy, the scale set makes no guarantees about the order of virtual machines being brought down. The scale set might take down all virtual machines at the same time to perform upgrades.
Automatic upgrade policy is best suited for DevTest scenarios where you aren’t concerned about the uptime of your instances while making changes to configurations and settings.
Manual upgrade policy
With a manual upgrade policy, you choose when to update the scale set instances. Nothing happens automatically to the existing virtual machines when changes occur to the scale set model. New instances that are added to the scale set, utilize the most update to date models available.
Manual upgrade policy is best suited for workloads where you require more control over when and how instances are updated.
Rolling Upgrade Policy + MaxSurge
With a rolling upgrade policy, the scale set performs updates in batches. You also get more control over the upgrades with settings like batch size, max healthy percentage, prioritizing unhealthy instances and enabling upgrades across availability zones. Additionally, you can enable MaxSurge which will create new virtual machines to replace virtual machines running in the old model. Using MaxSurge ensures your scale set does not see any reduced capacity during an upgrade.
Rolling upgrade policy is best suited for production workloads that require a set number of instances always be available. Rolling upgrades is the safest way to upgrade instances to the latest model without compromising availability and uptime.
Try the upgrade policies for Virtual Machine Scale sets today.

Available: Announcing kube-egress-gateway for Kubernetes
Status: Now Available
kube-egress-gateway is an open-source project that offers a scalable and cost-efficient solution for configuring fixed source IPs for Kubernetes pod egress traffic on Azure. The kube-egress-gateway components run within Kubernetes clusters—whether managed (Azure Kubernetes Service, AKS) or unmanaged—and use one or more dedicated Kubernetes nodes as pod egress gateways, routing pod outbound traffic through a WireGuard tunnel.
Compared to existing methods, such as creating dedicated Kubernetes nodes with a NAT gateway or assigning instance-level public IP addresses and scheduling only specific pods on these nodes, kube-egress-gateway is more cost-efficient. It allows pods requiring different egress IPs to share the same gateway and be scheduled on any regular worker node.

Public Preview: Geo-Replication for Azure Service Bus Premium
Status: In Preview
We are excited to announce the public preview of the new Geo-Replication feature for Azure Service Bus in the premium tier. This feature ensures that the metadata and data of a namespace are continuously replicated from a primary region to a secondary region. Moreover, this feature allows promoting a secondary region at any time. The Geo-Replication feature is the latest option to insulate Azure Service Bus applications against outages and disasters.
The Geo-Replication feature implements metadata and data replication in a primary-secondary replication model. It works with a single namespace, and at a given time there’s only one primary region, which serves both producers and consumers. There is a single hostname used to connect to the namespace, which always points to the current primary region.
After promoting a secondary region, the hostname points to the new primary region, and the old primary region is demoted to secondary region. After the new secondary has been re-initialized, it is possible to promote this region again to primary at any moment.

Public Preview: Force detach zone redundant data disks during zone outage
Status: In Preview
We are excited to announce the public preview support to force detach ZRS data disks from a VM residing on a zone impacted by failure. Customers will now be able to detach the ZRS data disks and attach them to another VM, decreasing the RTO.
Zone-redundant storage (ZRS) synchronously replicates your Azure managed disk across three Azure availability zones within the region providing 99.9999999999% (12 9’s) of durability over a given year. Zone redundant storage (ZRS) option for Azure managed disks is supported on Premium SSDs and Standard SSDs.

Custom formatting model advisor report in HTML
When generating a model advisor report, in the Model Advisor toolstrip it is possible to add a pdf or word template for your report. Is there a method for doing this for the HTML files? Or simply insert a section of code?

Using dlarray with betarnd/randg
I am writing a custom layer with the DL toolbox and a part of the forward pass of this layer is making draws from a beta distribution where the b parameter is to be optimised as part of the network training. However, I seem to be having difficulty using betarnd (and by extension randg) with a dlarray valued parameter.
Consider the following, which works as expected.
>> betarnd(1, 0.1)
ans =
0.2678
However, if I instead do the following, then it does not work.
>> b = dlarray(0.1)
b =
1×1 dlarray
0.1000
>> betarnd(1, b)
Error using randg
SHAPE must be a full real double or single array.
Error in betarnd (line 34)
g2 = randg(b,sizeOut); % could be Infs or NaNs
Is it not possible to use such functions with parameters to be optimised via automatic differentiation (hence dlarray)?

F3 Users – Open / Edit files on File Server / Mapped Drives
Hi All
I hope you are well.
Anyway, we have a lot of F3 users and have deployed a Custom OMA-URI policy that sets Office apps to open in Edge.
So far so good, however, this seems to only work for local files.
Our F3 users also need to be able to Open / Edit files stored on a File Server / Mapped Drive in Office Web Apps.
Is this possible? And can it be pushed out via Intune?
Info greatly appreciated.
Stuart

SharePoint REST API v2 delta nextlink
I’m using the SharePoint REST API v2 with a driveitem delta query and when I add an expand odata query, it returns the expanded information on the first response (200 items), but does not return it on any response using the returned “@nextlink”.
Query:
/drives/{driveId}/root/delta?expand=publication,sharepointIds
also tried:
/drives/{driveId}/root/delta?$expand=publication,sharepointIds
The same query in Graph will return the values correctly.

New Blog | Update on the Deprecation of Admin Audit Log Cmdlets
We wanted to provide you with an important update to the deprecation schedule for the two Admin Audit Log cmdlets, as part of our ongoing commitment to improve security and compliance capabilities within our services. The two Admin Audit Log cmdlets are:
Search-AdminAuditLog
New-AdminAuditLog
As communicated in a previous blog post, the deprecation of Admin Audit Log (AAL) and Mailbox Audit Log (MAL) cmdlets was initially planned to occur simultaneously on April 30th, 2024. However, to ensure a smooth transition and to accommodate the feedback from our community, we have revised the deprecation timeline.
We would like to inform you that the Admin Audit Log cmdlets will now be deprecated separately from the Mailbox Audit Log cmdlets, with the final date set for September 15, 2024.
This change allows for a more phased approach, giving you additional time to adapt your processes to the new Unified Audit Log (UAL) cmdlets, which offer enhanced functionality and a more unified experience.
What This Means for You
The Admin Audit Log cmdlets will be deprecated on September 15, 2024.
The Mailbox Audit Log cmdlets will have a separate deprecation date, which will be announced early next year.
We encourage customers to begin transitioning to the Unified Audit Log (UAL) cmdlet i.e. Search-UnifiedAuditLog as soon as possible. Alternatively, you can explore using the Audit Search Graph API, which is currently in Public Preview and is expected to become Generally Available by early July 2024.

Windows Admin center V2 Authentication issue
Windows Admin center V2 “Modernized” v2.0.01 will not operate in Windows Authentication mode. If you run the installer in Remote Express mode, it is set to Forms Authentication. This mode will not allow a login with an Active Directory administrator the V2 gateway is joined to, only the local machine administrator.
If you rerun the setup in custom mode and attempt to indicate Kerberos / Windows Authentication the gateway will not run. If you use the powershell admin script to run the command “Set-WACLoginMode -Mode WindowsAuthentication” on a functioning gateway in Forms auth mode, the gateway will crash/not run.
Both methods of setting integrated authentication produce this .NET runtime error below. Running the indicated netsh command produces no change in behavior and no change in future .NET runtime errors. Running a netsh show command clearly displays the indicated urlacl exists. The gateway server OS is Windows 2022 STD Desktop Exp. This is not installed SxS with V1 gateway. V1 gateway operates without issue on this server when installed.

New Blog | How to break the token theft cyber-attack chain
By Alex Weinert
We’ve written a lot about how attackers try to break passwords. The solution to password attacks—still the most common attack vector for compromising identities—is to turn on multifactor authentication (MFA).
But as more customers do the right thing with MFA, actors are going beyond password-only attacks. So, we’re going to publish a series of articles on how to defeat more advanced attacks, starting with token theft. In this article, we’ll start with some basics on how tokens work, describe a token theft attack, and then explain what you can do to prevent and mitigate token theft now.
Tokens 101
Before we get too deep into the token theft conversation, let’s quickly review the mechanics of tokens.
A token is an authentication artifact that grants you access to resources. You get a token by signing into an identity provider (IDP), such as Microsoft Entra ID, using a set of credentials. The IDP responds to a successful sign-in by issuing a token that describes who you are and what you have permission to do. When you want to access an application or service (we’ll just say app from here), you get permission to talk to that resource by presenting a token that’s correctly signed by an issuer it trusts. The software on the client device you’re using takes care of all token handling behind the scenes.
