where did the names go in outlook contact lists?
I am force to use the old outlook in order to send an email to my contact list. So I repopulated the contact list due to a meltdown and now I see that only the email address shows–no names in the contact list. What am I doing wrong?

Know if Serialport is connected (in App Designer program); ishandle() always true
I open a serial port to my Arduino and it usually works. I’m trying to take care of various errors, for one of which I need to know if the port handle is there and connected or not. In Command window I can tell when ishandle(MyCom) returns a logical answer
ishandle(app.PicoCom)
ans =
0×0 empty logical array
But programatically determining if it’s there, say with
ishandle(app.PicoCom) == false
ans =
0×0 empty logical array
Doesn’t work, it’s always true. How do I ask a false logical array if it’s false and why does this have to be so hard? Does anybody really need an array response to ishandle(app.PicoCom)? if ~ishandle(app.PicoCom) should be enough.
I also tried if ~exist(…) and even isstr(app.PicoCom.Port) but they don’t work when it’s not a handle.
BTW, ishandle() is only described as for graphic objects and figures and the existing answer doesn’t answer my question

Wireless connection to PI4 Bullseye ad-hoc mode
We have sucessfully programmed our application to run python scripts on a Pi4 when it is connected to our network via the ethernet lan connection.
We need to go to the next phase where the comptuer connects wirelessly to the PI without a network present. Matlab indicated that this was possible when we reviewed the project during the software decision proesses.
We think we need to turn the PI into a server, however we are not finding a resource with a working link that actually accomplishes this task. Any guidance or direction to links that are known to work would be greatly appreciated.

Using Shortcuts in MATLAB
Hello Everyone , I am a VS Code user and new to MATLAB , I have many extensions in VS Code which makes my work easier and effortless
I feel that MATLAB is missing some of these features. for example , in VS Code, I frequently use Shift + Alt + Down Arrow or Up Arrow to duplicate lines, but I couldn’t find a similar command in the MATLAB documentation.
I also use several commands repetitively. Is there a way to create shortcuts for these commands in MATLAB? Additionally, I’d like to know if it’s possible to customize these shortcuts, as I am accustomed to different keybindings, and MATLAB’s default shortcuts are not quite what I’m used to.

=VSTACK(Table1, Table2, Table3….Table27). Column G on the dashboard lists dues dates, and I would like to be able to sort the entire dashboard by column G.
The end result should be a dashboard that shows all the data from all the sheets and lists the rows in chronological order according to column G. I have tried to add a SORT function in front of the VSTACK with no luck (produces a #VALUE! error).

Optimize Azure Stack HCI with the Well-Architected Framework
Azure Stack HCI is a hyperconverged infrastructure (HCI) solution that provides storage, network, and compute resources in on-premises or edge locations. It supports the creation and management of Windows and Linux virtual machines (Arc VMs), AKS clusters for containerized workloads, and other Azure Arc-enabled services, such as SQL Managed Instance (MI) and Arc-enabled machine learning (ML). Azure Stack HCI is connected to Azure for streamlined deployment and management, which provides a unified and consistent management experience using Azure portal and Azure Update Manager for updates, and the Arc Resource Bridge for workload orchestration and provisioning operations.
You can use Azure Stack HCI and Azure Arc capabilities to keep business systems and application data on-premises to address data sovereignty, regulation & compliance, and latency requirements. For more information, please see What is Azure Stack HCI?
The Azure Well-Architected Framework (WAF) provides prescriptive guidance and recommendations for architects to use when creating or reviewing cloud solutions. The WAF guidance is organized into five pillars, Reliability, Security, Cost Optimization, Operational Excellence, and Performance Efficiency. Incorporating the recommendations into platform and workload designs helps to ensure reliable, scalable, and performant architecture patterns are implemented for cloud solutions.
Today I am announcing the Azure Well-Architected Framework Service Guide for Azure Stack HCI. Like other service guides, this guide for Azure Stack HCI contains design checklists, and detailed configuration recommendations that can assist cloud architects in designing and deploying Azure Stack HCI in line with the guiding tenets of the Well-Architected Framework: Reliability, Security, Cost Optimization, Operational Excellence, and Performance Efficiency.
When you’re designing a new Azure Stack HCI deployment, this guide offers advice to make sure your platform is set up effectively. Use the design checklists for tailored recommendations during planning. Each recommendation includes a rationale and a link to product documentation for more details. If you’ve already implemented Azure Stack HCI, this guide can direct you to enhance your platform or workload designs in line with the WAF pillars.
Updated Azure Architecture Center pattens
To accompany the new Azure WAF Service Guide for Azure Stack HCI, we have published new and updated Azure Architecture Center (AAC) reference architectures, as detailed below:
1. Azure Stack HCI – baseline reference architecture for guidance and recommendations for configuring Azure Stack HCI infrastructure as a reliable platform to deploy and manage highly available virtualized, and containerized workloads.
2. Azure Stack HCI – three-node storage switchless architecture for guidance and recommendations for deploying Azure Stack HCI using a three-node storage switchless network architecture.
We plan to publish more Azure Stack HCI Infrastructure and Workload design patterns in the Azure Architecture Center in the coming months, which will provide additional guidance and recommendations.
If you have any feedback or comments in relation to the Azure Stack HCI WAF content, please send an email to AzS-WAF-Feedback@microsoft.com

Determining gait cycle from heel marker motion capture data
I have motion capture data of participants walking, jogging and running on a treadmill. Participants had a marker on each heel. I need to determine each gait cycle from this data so that I can then calculate breast range of motion, velocity and acceleration for each gait cycle.I have motion capture data of participants walking, jogging and running on a treadmill.

How do you use a one parameter (S11), (s1p extension) file to model a direct RF chip input in RF Budget analyzer.
I’m trying to model the TI AFE7906 and have some one port S11 input reflection files provided that describe the input behaviour of the receive ports. How can these files be entered in the RF Budget Analyer (in the "S-Parameters" element) to do this? I realize the app is looking for a two port file for it’s cascade analysis but I need to model the Rx input at the end of the RF chain.I’m trying to model the TI AFE7906 and have some one port S11 input reflection files provided that describe the input behaviour of the receive ports.

Formula for balance criteria
I only want to populate 5 in the calculated field if the balance is greater than 300 and less than 1000. Is it only populating if any of the fields fall below 300. Any suggestions?

how do I merge the 3 accounts or delete the new email
Hello
Please i need your help on this issue.
I originally had a personal account with the email XXX@gmail.com. Once Teams stopped supporting Gmail addresses I added XXX@outlook.com. Now that I have upgraded to Business Basic I have added another email XXX@xxx.onmicrosoft.com.
I do not have the time or energy to monitor 3 business email accounts! I already have business cards and headed letter templates so I do not wish change my business email.
So my question is how do I merge the 3 accounts or delete the new email? I wish to retain XXX@outlook.com and require Teams etc to apply Business Basic parameters to this account not add an additional one.

Department not displayed
Hi everyone,
I’m working with pnp-modern-search to add these web parts to our intranet. However, even though I’ve selected the “department” field, it doesn’t show up in the list results. Only the person’s name, title, email, and phone number are displayed.
I’ve even used the SharePoint query tool, and the Department property is filled in, but for some reason, it’s not showing up in the results.
I’ve also set up the results to be sorted by department, and the search sorts them just fine. The only issue is that the department field isn’t displayed.
Does anyone with experience using this web part have any idea where I might look to find the cause of this issue?
Thank you,
