filling Index issues imfindcircles
Im having issue where i think the index is looking for instances of detected circles but it either is not filling the index or maybe there isnt enough to fill the array but im having issue getting this to work. its from the help documentation so i expected it to just work but im still having trouble and thus am having trouble understanding how to use imfindcircles. I tried using edge(canny) and using a binary image to see if that would make it easier to find circles but im still hvaing issues.
A = imread(‘coins.png’);
imshow(A)
[centers, radii, metric] = imfindcircles(A,[15 30]);
centersStrong5 = centers(1:5,:);

Help with excel formulas
Good evening,
I am trying to create a holiday tracker to track my colleagues holiday allowance.
So my plan is the following.
Cell A1 hours Used
Cell B1 hours remaining
Cell C1 Annual holiday Allowance
So now let say the holiday allowance is 265. John Smith booked 10 hours so that 10 hours will be deducted from the 265 which would be 255. This part is easy enough just by doing
=SUM(A1-C1)
But the problem I have got is if John Smith booked a 5-hour holiday a few weeks later, and you updated the cell “Hours Used” from 10 hours to 5 hours, the total would be then 260. But realistically, it should be 250 instead due to previous holiday . So my question is how would I go about doing this. Any help or advice would be highly appreciated.
Thank you

How to maintain a fixed range when cell is added
=SUM(J10:J58+G10:G58)
The above formula works perfectly fine
However, each week an additional cell needs to be inserted in J10:J58
This causes the formula to return an error
For example:
J34 is moved down one cell by performing the step Insert/Shift Cell Down.
By doing this my original formula changes from:
=SUM(J10:J58+G10:G58)
to:
=SUM(J10:J59+G10:G58)
To fix it I manually change it back to
=SUM(J10:J58+G10:G58)
How can I prevent J58 changing to J59 when a cell is inserted into the range.

How to maximize achievable Rate for spectrum sharing in MIMO?
Hello, I am simulating a paper. I want to maximize achievable rate but there is an error in my code. the problem is maximiz (sum(log(1 + p2_k/ (sigma^2 + norm(w2_k,2)^2)))) when P2 and W2 are my variable matrices subject to 0=< p2_k =< tilde_P2 and sum( p2_k * xi_k =< zeta1_l. I used CVX function for optimization but I am not sure if it is true or not. my error is "Disciplined convex programming error:

Error with addpoints when trying to animate a trajectory following a marker
I am trying to animate a trajectory following a marker.
Here is the problematic part of my code:

TOC RD generating page 1 instead of correct page numbers
I am using Word Version 2407 (Build 17830.20084) with Office 365 Apps for Business. For years, we have created TOCs pulling from multiple files using the TOC RD field. However, now instead of the correct page numbers, it shows 1 (or occasionally the first page number of one of the files). This first started on someone else’s machine and until now, I was able to successfully generate a correct TOC for them. This is happening with multiple documents. We’ve tried manipulating the page number and TOC fields, safe mode, replacing normal.dotm, and repairing the Office install. Note that the TOC works just fine on an individual document (i.e., when not using RD). Any ideas?

Can I restore a file from an over written partition?
I recently had to restore a backed-up system partition, which unfortunately resulted in the overwriting of all data on my C drive. As a result, I ended up losing certain files that were stored in my AppData/Local/Kemper Amps folder prior to the restore. Despite trying multiple recovery programs, I have been unsuccessful in recovering those specific files.
Do you have any suggestions or solutions that do not involve the common advice of backing up files in advance? Any assistance would be greatly appreciated. Thank you.

Change cell between 2 colours based on upcoming date 2+ years in advance
Hi there,
I’ve got a project on at the minute, where I need to have cells containing dates change between colours under 2 conditions. (Technically 3 but I’ve already sorted the last one out.)
The dates are split into 2 columns, one for the date the source is deleted, and the other is when the source document should be downloaded by. The source deletion date is 6 years after the source date, and the source download by date is 2 years prior to the deletion date.
My requirements are as follows:
Orange
When the source deletion date is within 4 years and 25 days of today’s date.When the source download date is within 2 years and 25 days of today’s date.
Red
When the source deletion date is within 4 years of today’s date.When the source download date is within 2 years of today’s date.
Basically, I want a 25 day window where both cells in D and E go from white to orange – showing it needs to be tasked, and then orange to red – showing that the 25 day window has passed.
See example below:
I’ve spent a good time trying to work out the cell formatting for this, and just can’t get it to work. Either it stays orange, or doesn’t pick it up at all when I test it with different dates.
Any help would be appreciated, and step-by-step would also help as I’m still new to this type of Excel.
P.S. In my actual sheet, I’ve got a formula in the D and E columns to pick up the date in C, and add 6 years and 4 years respectively.
I’ve also already got a rule for the green colour whereby if “Yes” is noted in G column, then it will mark all dates as green (completed) regardless of today’s date.

The Importance of Validation HostPools in AVD Deployments: Lessons from the CrowdStrike Global Issue
In the rapidly evolving world of IT, ensuring the stability and reliability of virtual desktop environments is crucial. Azure Virtual Desktop (AVD) deployments offer a flexible and scalable solution for organizations, but with this flexibility comes the need for rigorous testing and validation. This article explores the importance of validation host pools in AVD deployments, particularly for testing updates before pushing them to production, and draws parallels to the recent global issue caused by CrowdStrike.
The Role of Validation Host Pools in AVD are a critical component in the deployment and maintenance of AVD environments. These pools allow organizations to test updates and changes in a controlled environment before they are applied to the production environment. This process helps in identifying potential issues that could disrupt user experience or cause downtime.
Key Benefits of Validation Host Pools:
Early Detection of Issues: By testing updates in a validation host pool, IT teams can identify and resolve issues before they impact the production environment.
Minimized Downtime: Validation helps in ensuring that updates do not introduce errors that could lead to downtime, thus maintaining business continuity.
Improved User Experience: Regular testing in a validation environment ensures that end-users experience fewer disruptions and maintain productivity.
The CrowdStrike Global Issue: A Case Study:
Recently, a faulty software update from CrowdStrike led to a massive global outage, affecting millions of Windows computers. This incident underscores the importance of thorough testing and validation before deploying updates to production environments.
What Happened:
A software update for CrowdStrike’s Falcon Sensor caused Windows computers to crash, leading to widespread disruptions across various sectors, including airlines, banks, and emergency services.
The issue was traced back to a logic error in the update, which was not detected before the update was pushed to production.
Lessons Learned:
Critical Need for Validation: The CrowdStrike incident highlights the necessity of having robust validation processes in place. If the update had been thoroughly tested in a validation environment, the issue could have been identified and rectified before causing widespread disruption.
Continuous Monitoring: Even after deploying updates, continuous monitoring in a validation environment can help in quickly identifying and mitigating any unforeseen issues.
To implement Validation Host Pools in AVD, follow these steps:
Create a Host Pool: Use the Azure portal, PowerShell, or Azure CLI to create a new host pool or configure an existing one as a validation environment.
Define the Validation Environment: In the Azure portal, select the host pool, go to properties, and enable the validation environment setting.
Regular Testing: Ensure that the validation host pool is used regularly for testing updates and changes. This should mimic the production environment as closely as possible.
The recent CrowdStrike global issue serves as a stark reminder of the importance of validation host pools in AVD deployments. By implementing and maintaining a robust validation environment, organizations can significantly reduce the risk of disruptions and ensure a seamless user experience. As the IT landscape continues to evolve, the role of validation host pools will only become more critical in maintaining the stability and reliability of virtual desktop environments.

How to Import Gmail Contacts into Outlook?
I’ve been struggling for a long time to synchronize my Outlook contacts with my Gmail contacts, and I’m looking for a solution to import Gmail contacts into Outlook while avoiding duplicates. Is there a method that allows for seamless integration without having to delete all existing Outlook contacts before importing from Gmail? Furthermore, the limitation of being able to delete only 10 Outlook contacts at a time seems to hinder the process. Is there a workaround to streamline this tedious task and achieve efficient contact management between the two platforms?

Keeping customers informed of the latest status on the incident through the Azure Status Dashboard here.
We’re working around the clock and providing ongoing updates and support. Additionally, CrowdStrike has helped us develop a scalable solution that will help Microsoft’s Azure infrastructure accelerate a fix for CrowdStrike’s faulty update. We have also worked with both AWS and GCP to collaborate on the most effective approaches.
While software updates may occasionally cause disturbances, significant incidents like the CrowdStrike event are infrequent. We currently estimate that CrowdStrike’s update affected 8.5 million Windows devices, or less than one percent of all Windows machines. While the percentage was small, the broad economic and societal impacts reflect the use of CrowdStrike by enterprises that run many critical services.
This incident demonstrates the interconnected nature of our broad ecosystem — global cloud providers, software platforms, security vendors and other software vendors, and customers. It’s also a reminder of how important it is for all of us across the tech ecosystem to prioritize operating with safe deployment and disaster recovery using the mechanisms that exist. As we’ve seen over the last two days, we learn, recover and move forward most effectively when we collaborate and work together. We appreciate the cooperation and collaboration of our entire sector, and we will continue to update with learnings and next steps.

On July 18, CrowdStrike, an independent cybersecurity company, released a software update that began impacting IT systems globally. Although this was not a Microsoft incident, given it impacts our ecosystem, we want to provide an update on the steps we’ve taken with CrowdStrike and others to remediate and support our customers. Since this event began,…

How to create http MessageBody body with fields that contain dashes
I would like to create http message bodies with fields that contain dashes. I haven’t been able to find a workaround for Matlab disallowing hyphens (dashes) in the var names.
Here is what I’m trying to do – for illustration – I have an underscore in place of a hyphen the "test_var" (below)
Even after generating the RequestMessage (req1 below), you cannot change "test_var" to "test-var" because the RequestMessage is still storing the request as a struct (not as a string which could be modified).
method = matlab.net.http.RequestMethod.POST;
header = matlab.net.http.HeaderField(‘Content-Type’, ‘application/json’);
header = addFields(header,’User-Agent’, ‘my-client/99.9’);
header = addFields(header,’Accept’, ‘application/json’);
% Struct approach
struct1 = struct(‘login’, ‘me’, ‘password’, ‘pw123’, ‘test_var’, true)
body1 = matlab.net.http.MessageBody(struct1)
req1 = matlab.net.http.RequestMessage(method,header,body1)
show(req1)
POST
Content-Type: application/json
User-Agent: my-client/99.9
Accept: application/json
{"login":"me","password":"pw123","test_var":true}
