ADF Lookup Stored Procedure Error
I have a stored procedure that has the following format:
If (@x = 1)
BEGIN
RETURN SCOPE_IDENTITY()
END
ELSE
BEGIN
RETURN COLUMN1
END
I’m using a Lookup in ADF and it gives me an error: The specified Stored Procedure is not valid. It could be caused by that the stored procedure doesn’t return any data.
How can I get the value from this stored procedure in ADF and save it to a variable without changing the stored procedure to say SELECT ID = @Scope_Identity() and keeping the RETURN xxxxx?

Multilayer Perceptron with More Than One Output and Data Interpretation?
I haven’t used Matlab’s ML or deep learning toolbox since maybe 2022. In the last year, it seems like MathWorks intentionally made the ML portion of Matlab unusable. I’m hoping someone here can help me out because rolling back my matlab two years will make a lot of my recent work unstable. I’ve done my best to document my process here. Error messages are given in italics for ease of reading.
I have some data that is represented by four doubles that are normalzied to between 0 and 1. I would like to use these four doubles to predict two doubles that are also between 0 and 1. I would like to make a multilayer perceptron that will take in the four values and spit out the two values. However, createMLPNetwork doesn’t appear to support multiple outputs – at least, the documentation for it doesn’t explain how to do so. So I have tried to make a MLP from scratch using the following code:
%% Prep NN architecture
layers = [
inputLayer([4, 1], "CU", name="in")
flattenLayer
fullyConnectedLayer(20, name="fc1")
reluLayer
fullyConnectedLayerB(16, name="fc2")
reluLayer
fullyConnectedLayer(12, name="fc3")
reluLayer
fullyConnectedLayer(numel(data{1,1}), name="output")
softmaxLayer
];
net = dlnetwork(layers);
[trainedNet, info] = trainnet(train, layers, "mse", opts);
Attempting to run this gives me the following results:
Error using trainnet (line 46)
Error forming mini-batch for network input "in". Data interpreted with format "CU". To specify a different format, use the InputDataFormats option.
Error in trainRutileModel (line 107)
[trainedNet, info] = trainnet(train, layers, "mse", opts);
Caused by:
The data format must have a batch dimension.
I tried to get around using the generic inputLayer function by using the more specific functions like featureInputLayer but replacing the inputLayer with a featureInputLayer throws the following:
Error using trainnet (line 46)
Number of observations in predictors (4) and targets (2) must match. Check that the data and network are consistent.
Error in trainRutileModel (line 107)
[trainedNet, info] = trainnet(train, layers, "mse", opts);
So that won’t work because I only have two output data points. The same happened when I tried imageInputLayer. Then I tried replacing "CU" with other values – the following error is for "BU" but the other errors are the same – but got the following:
Error using dlnetwork/initialize (line 558)
Invalid network.
Error in dlnetwork (line 167)
net = initialize(net, dlX{:});
Error in trainRutileModel (line 104)
net = dlnetwork(layers);
Caused by:
Layer ‘fc1’: Invalid input data for fully connected layer. The input data must have exactly one channel dimension.
So then I tried flattening the output and got the following error:
Error using dlnetwork/initialize (line 558)
Invalid network.
Error in dlnetwork (line 167)
net = initialize(net, dlX{:});
Error in trainRutileModel (line 105)
net = dlnetwork(layers);
Caused by:
Layer ‘flatten’: Invalid input data. Layer expects data with a channel dimension, but received input data with format "BU".
I’m really not sure what to do here. I have no idea why MathWorks would make this so much more difficult to use and give so much less, and more opaque, documentation. If anyone has any ideas on how to make this work, I’d be happy to hear them. In the meantime, I’m going to take another crack at the createMLPNetwork function and hope that when MathWorks says "a black-box continuous-time or discrete-time neural state-space model with identifiable (estimable) network weights and bias," by "states" they mean "outputs."I haven’t used Matlab’s ML or deep learning toolbox since maybe 2022.

Determine the indice of real maximum using accumarray function
I’m doing signal analysis on the peaks and valleys of a sinusoidal signal. Using accumarray has been quite effective at determining the extrema, but I’m seriously struggling with what should be a simple part of my implementation. Currently the returned peakLoc values are not integer timesteps, but a decimal average of all the timesteps that are considered part of the peak. The only new functionality I need is to get the real integer timestep for the highest (or lowest) extrema. Whether there is an option for the single accumarray line with @mean or another way, I don’t care. Over the past three days I have been slopping together different nested loops to try to pin down the behavior I want and I’m sure there’s got to be a simple way to accomplish this.
I’m sure there’s a lot of other ways I could improve this code, but I just need it working. I’m not experienced and constantly bang my head against indexing problems (whether mixing up dimension, logical indexing oddities, etc.) and other beginner problems.

Conditional Formatting for column based off data in another column
Hi! I am looking to apply conditional formatting to cells in Column AC when adjacent cells in column AB are not blank.
For example, both columns will have dates. Column AB is start date, Column AC is finish date.
I would like any cell in Column AC to change color when its adjacent cell in Column AB has a date entered IF AC cell is blank. Once cell in AC also has a date, it would return to no fill format.

How can I make a power load which uses different power for a day?
I want to make a power load which consumes different power for a day. I have a data that shows how much power was consumed by a building for a day.
So I used Dynamic load block, but I failed to load the data to the block.

Please help as I am struggling to solve this homework problem.
An H-section copper conductor carries an overload current of 54000 A. Under steady state conditions, the surface temperature is 60°C.
The dimensions of the bar are given in Figure 1 overleaf, and you are asked to use a numerical method to produce a mesh plot of the temperature distribution and a graph of the temperature distribution along the line y = 0.
The electrical resistivity, ρ, of copper is 2 × 10-8 Ω m, and the thermal conductivity, κ, is 0.311 kW m-1 K-1.
The governing differential equation is ∂2T + ∂2T + g = 0 (1)
∂x2 ∂y2 κ where g is the (constant) generation rate of heat per unit volume:
g = i2ρ (2) and i is the current density.
Using an appropriate Numerical Technique:
Determine the temperature distribution to an accuracy of 4 significant figures
You are expected to hand in the following by the submission date:
Hints
The Gauss-Seidel technique used in Tutorial 9 can be adapted to the present problem by including the additional term g/κ in the finite difference equation. You can generate a mask array as in Tutorial 9 to specify the region of the array covered by the H cross- section.
Try calculating the solution over a square mesh for a range of step lengths h = 5 mm, 2.5 mm, 1.25 mm…
You can if you wish make use of the symmetry of the problem and model just one quarter of the conductor. However, the boundary conditions then become more difficult to apply.
The H section is of width 40mm, depth 30mm and cut outs on top and bottom of depth 10x width 20 mm
Any help would be most appreciated

Access denied, sending domain does not pass DMARC verification and has a DMARC policy of reject
This is super annoying. I’m not using Microsoft “defender”. I’m on the receiving end of its stick.
I noticed that when I start sending emails back and forth with some business that uses Microsoft 365 Defender to handle their emails, it works for a few initial emails. Maybe .about 5. But then all of a sudden my messages start bouncing back with the following message:
“Diagnostic-Code: smtp;550 5.7.509 Access denied, sending domain ____.com does not pass DMARC verification and has a DMARC policy of reject.“
I tested my email for passing DMARC and found no issues with multiple services that do those DMARC tests. So the problem is clearly with the “defender“.
I also noticed that if I resend the message the next day, it goes through. But only if I don’t send too many emails – which is generally about 5.
Does anyone have any idea when will they fix it?

Teams I no longer belong to still reappear in my Teams list
For several years, I’ve noticed that old teams I no longer belong to still appear in my Teams list. These are teams I initially created but later manually left through the Teams app. They show up in both Teams for the Web and Teams Desktop, affecting both Classic and New Teams versions. I assumed it was a bug that would eventually be fixed, but after about three years, they still persist.
I’ve tried clearing the Teams cache, browser cache, reinstalling Teams, and other troubleshooting steps, but the issue remains. It seems to be some kind of bug or persistent cloud caching. Even after leaving these teams years ago, they still reappear. When I click on one, I get an error message saying I no longer have access, and then it disappears, only to return within a day or two. Has anyone else experienced this issue?

New Outlook for Windows: a guide for Executive Assistants and Delegates – part 2
This blog captures some calendar tips to help executive assistants and delegates better navigate their time management needs in the new Outlook.
1. Find time and request in-person event
When scheduling a meeting, click on ‘Find a time’ to easily find suitable time slots on the attendee’s calendars. You can view availability by hovering on the attendee icon. You can also request in-person attendance by turning on the ‘In-person event’ toggle on. You can still add a Teams meeting link for attendees who may not be able to join in person.
2. Use Scheduling Assistant
Use the scheduling assistant to easily find time for meetings. In the new Outlook, you can view the attendee time zones and schedule labels in the Scheduling Assistant. Note that attendee time zones are shown only if at least one attendee is in a different time.
3. Automatic online meetings
In the new Outlook, all meetings are online by default. The Teams meeting toggle is turned on when you add attendees to a meeting. Unlike classic Outlook, the Teams meeting link and details are added after the invite is sent. You can then view the meeting invite to see and copy the Teams meeting details. We are working to update this behavior and pre-create meeting links so you will see the experience match classic Outlook in future.
Note – you can update every meeting online setting from Settings> Calendar > Events and invitations and enable or disable ‘Add online meeting to all meetings’.
If you are using 3rd party online meeting providers like Zoom or Cisco WebEx, you will also see those as meeting provider options in this setting, provided you have their web add-in installed. Learn more every meeting online here.
4. Hide attendee list
You can now choose to hide the attendee list from being visible to users who receive the meeting invite. When creating a new meeting, select ‘Response options’ and click on ‘Hide attendee list’
5. Attendees can add rooms
In the new Outlook, attendees can add rooms by forwarding the meeting invite to the relevant rooms. The meeting room will then be visible to all attendees.
6. Edit events in a series
The new Outlook for Windows has the following options for editing a meeting series –
This event – this will only update the selected instance of the meeting series.
This and all following events – this will only make changes to the selected and following instances of the meeting series and the older meeting instances will not be changed. This option does not exist in classic Outlook for Windows.
All events in the series – this will update all events in the meeting series.
7. Duplicate a meeting
Right click on an event in the calendar surface and select ‘Duplicate event’ to it. You can also do this from the meeting form ribbon.
8. Add multiple Time Zones in calendar
Easily manage meetings across different time zones in new Outlook. New Outlook allows you to add up to 20 time zones in the calendar, whereas classic Outlook allows adding only 3 time zones.
9. Use executive’s categories in calendar
Right click on an event in the calendar view and click ‘Categorize’ to apply executive’s categories. We plan to allow executive admins to manage executive’s categories in future.
10. Receive shared calendar notifications
In the new Outlook, users can opt to receive notifications on changes to events in the shared calendar. This capability is extended to both the executive and executive assistant/delegate. You can select the calendars you want to opt in for notifications from Settings> Calendar > Shared Calendars> Calendar updates.
11. ‘Don’t send response’ RSVP tracked
In classic Outlook, if the user chooses ‘Do not send response’ while RSVPing, the organizer will not be able to track that individual RSVP.
However, in the new Outlook, if the user unchecks ‘Email organizer’ while RSVPing, even though there will not be a visible response email sent to the organizer, the organizer will still be able track that RSVP as long as the organizer and the RSVPing attendee are in the same M365 tenant (or organization).
We plan to support tracking across different tenants in future.
12. Preserve declined meetings on the calendar and RSVP’d meetings in inbox
Preserve declined meetings on the calendar so that you can still be aware of it and update RSVP later if needed. This can be enabled by selecting Settings > Calendar > Events and invitations and clicking the ‘Save declined events’ checkbox.
Meetings that have been RSVP’d to, can also be retained in the inbox so that you can easily find them later. This can be done from Settings> Calendar > Events and invitations > Invitations from other people and selecting the ‘Delete invitations from inbox after responding’.
These settings will have to be enabled on the executive’s for them to be respected in the delegate calendar and inbox folder respectively.
13. Decline but follow a meeting
The new ‘RSVP option allows you to decline a meeting but still have access to the meeting chat, meeting recording and meeting notes. This is a great way to stay informed about discussions that you or your executives are unable to join.
This feature is rolling out so some users may not see it yet.
Share feedback
We encourage you to try new Outlook and share your feedback. You can submit feedback on the new Outlook experience from Help > Feedback. Please mention – “I am an EA” Or “I am a delegate” when adding comments.
To stay updated with the latest features in new Outlook, follow the roadmap.
This guide will also be published as a support article that will be linked here once available.

Managed HSM support for Azure Database for MySQL – Flexible Server (General Availability)
We’re happy to announce general availability of Azure Key Vault Managed HSM support for customer managed keys (CMK) in Azure Database for MySQL – Flexible Server!
What is Managed HSM?
Azure Key Vault Managed HSM (Hardware Security Module) is a fully managed, highly available, single-tenant, standards-compliant cloud service that enables you to safeguard cryptographic keys for your cloud applications, using FIPS 140-2 Level 3 validated HSMs. It ensures your data is stored and processed only within the region that hosts the HSM, ensuring data residency. Each Managed HSM instance is dedicated to a single customer and consists of a cluster of HSM partitions. All cryptographic operations, such as encryption, decryption, and validation, are performed inside the HSM.
Benefits of Managed HSM support for Azure Database for MySQL – Flexible Server
The Managed HSM feature allows you to use your own HSM-backed encryption keys to protect your data at rest in MySQL – Flexible Server instances. You can generate HSM-backed keys and import the encryption keys from a physical on-premises HSM using CMK’s bring your own key (BYOK) feature while maintaining full control over the keys.
Configuring Managed HSM for Azure Database for MySQL – Flexible Server
You can easily configure an Azure Key Vault Managed HSM for new or existing Azure Database for MySQL flexible servers by using the Azure CLI or the Azure Portal, as shown in the following screenshot:
When configuring Managed HSM, note that you must:
Deploy the Managed HSM in the same region as the MySQL flexible server.
Enable soft delete and purge protection.
Assign the User-assigned Managed Identity (UMI) the “Managed HSM Crypto Service Encryption User” role in RBAC.
Learn more
For more details about this feature, please see the article Data encryption with customer managed keys – Azure Database for MySQL – Flexible Server.
