Problem with multi-factor authentication

/ 2024-10-03

Hello, I am a registered and active Microsoft Partner with ID 1822164. I have two-factor authentication through the Authenticator app on my mobile phone. The phone is currently down and I can’t log into partner.microsoft.com. I have a new phone with Authenticator installed but I can’t make any changes to the account. I can provide any necessary identification information, my name and password are valid. Where can I request to turn off two-factor authentication to sign in and add my new phone?

Migrating Windows Server from ‘Hybrid Azure AD Join’ to ‘Entra ID Join (Cloud-Only)’

/ 2024-10-03

Hi everyone,

I need help with a scenario where I’m looking to move a server ( non DC ) from Microsoft Entra Hybrid Joined to cloud only (Entra ID) Joined only. The goal is to stop relying on the on-premises AD domain and make the server authenticate only through cloud-based accounts (Azure AD accounts).

I’d appreciate any guidance, documentation or best practices on how to properly handle this migration while ensuring minimal disruption.

Has anyone done this transition before?
What steps and considerations should I be aware of in terms of network configuration, Cost…. etc?

Thanks in advance for your help!

Interpolate pairs of values from matrix

/ 2024-10-03

I have a coarse 2D-matrix with [X,Y,Z]-values.
I want to input a Z-value and would like to interpolate possible values for the [X,Y]-pairs. These [X,Y]-pairs are then used for a fit. This means that for a given value of Z, if I choose any X value, Y can be calcualted and the other way arround.
I have tried the interp2 already, but it seems that I can only input X and Y values to get the interpolated Z value and not the other way around, where I input a Z-value and get a list of [X,Y]-pairs for that.

VALUE Error When Combining IF with SUMPRODUCT

Please I need assistance with IF and SUMPRODUCT formula that keeps returning a Value Error.

However, as shown in photo 1, while the formula returns the correct numbers for Customer B (which table is in the same workbook i’m using), it returns a Value Error when I link to an external workbook as shown in photo below:

Drop down in uitable to work like excel

/ 2024-10-03

I have an uitable and I want to have certain cells with a drop down. I know that this is done by using the functions categorical and table. The problem is that I need the table to accept empty values and show the empty values as a blank cell with the drop down functionality. If I add the empty option to a categorical this will show as <undefined>
Data = cell(21,2);

for i = 1:length(Data)
for j = 1:length(Data)
Data{i,j} = "";
end
end

fig = uifigure;
tab = uitable(fig);
opts = categorical({‘1′,’2’,”});

Data{2,1} = opts(3);

Column1 = Data(:,1);
Column2 = Data(:,2);

tab.Data = table(Column1,Column2);

By making the Columns editable and changing the <undefined> value it will show always one of the non-empty options entered in the categorical function and not allowing the cell to be empty (or <undefined>) anymore:

Is there a way to allow this types of cells to work like the drop downs works in Excel?

transform linear inequality constraints into bound constraints for optimization solvers

/ 2024-10-03

Suppose there are linear inequality constraints and are the parameters optimized by fmincon, lsqnonlin, or friends.
Since linear inequality constraints can generally not be enforced at intermediate iterations, I want to transform them into bound constraints which can be enforced at all iterations.
General idea:
If is dense and has rows (i.e, there are constraints), then we can make a "change of variables"
, where are the rows of , for instance, .
This leads to simple bound constraints . Does that make sense?
Specific problem:
My parameters represent interpolation values corresponding to interpolation points and the resulting interpolation function is supposed to be convex on the interpolation domain. For the specific case of linear interpolation, @Matt J showed that convexity is realized by increasing second order finite differences
(which represents a set of linear inequality constraints)
This can be transformed into simpler bounds on the new parameters by the change of variables

with

What I am really working with are smoother B-spline basis functions of higher degree using spapi function. @Bruno Luong showed that the linear inequality matrix is given by
% k: spline order, x: points where values y live
B = spapi(k,x,eye(length(x)));
Bdd = fnder(B,2);
A = Bdd.coefs’
and
is a sufficient condition for convexity.
I am wondering whether a change of variables (like for linear interpolation functions) can be applied here to transform the inequalities into bounds?
Any opinions are greatly appreciated!Suppose there are linear inequality constraints and are the parameters optimized by fmincon, lsqnonlin, or friends.

Sharepoint list created from Excel Export creates a allitemsg.aspx view and also goes to Edit mode

/ 2024-10-03

I think is easier to create and build columns using Excel formulas in Excel.

But when I Export the table to create a new sharepoint list it gets a default view called allitemsg.aspx ?

I like the format of the list since it keeps the columns very narrow.

But I manually have to delete the leftmost column, which is icon called Type.

The big problem is I don’t want to go directly into Edit mode. The list contains hyperlinks that should be easy to click.

Can I somehow restore to the standard view behaviour?

Hello,

I work as an AV integrator and we currently have roughly 100 Microsoft Teams Room machines installed.

Since last Tuesday we have been notified of multiple rooms (10 so far) where the Microsoft Teams Room account cannot login.

All these rooms have in common that the Microsoft Teams Room application has been updated (automatically) to version 5.2.115.0

Previous versions of the Microsoft Teams Room application do not show these issues.

Is there a way we can downgrade these machines to an older working version?

Cannot define a cell array of custom classes in function argument validation

/ 2024-10-03

I’ve a class like the following one:
classdef Session < handle
%SESSION Summary of this class goes here
% Detailed explanation goes here

properties (Access = private)
configurations (1, 🙂 cell {mustBeA(configurations, "App.Core.Configuration")}
end

methods (Access = public)
function this = Session()
this.configurations = {}
end
end
What I want to do is to declare che configuration property as a unidimensional cell array of a custom class, that can have 0 or more elements.
The problem is that I cannot instantiate it. When I try to do something like:
s = App.Core.Session()
I obtain the following error
Error using implicit default value of property ‘configurations’ of class ‘App.Core.Session’. Value must be one of the following types: ‘App.Core.Configuration’.
even if the App.Core.Configuration() class exists and it works (I’ve already unit tested it).
How can I declare correctly my configurations property?I’ve a class like the following one:

Why Notepad takes so much CPU?

/ 2024-10-03

Hi everyone.

I wonder why Notepad is taking so much CPU. I thought its a simple and light weight text editor but I noticed lately that its heavier than even chrome and firefox, and most of the time its on top in task manager.

Some people said the exe might not be genuine and might be a virus but I checked it and it was digitally signed by Microsoft.

SQL 服务器（SQL Server）是由微软公司开发的一款关系型数据库管理系统，在企业级应用中具有广泛的用途。

一、主要特点

强大的数据存储和管理能力：支持大规模数据存储，可以处理海量的结构化数据。无论是小型企业的业务数据，还是大型企业的复杂数据集合，SQL Server 都能提供稳定可靠的数据存储解决方案。提供高效的数据管理功能，包括数据的插入、更新、删除、查询等操作。通过优化的存储引擎和查询处理器，能够快速响应各种复杂的查询请求，提高数据处理效率。高可用性和可靠性：具备多种高可用性解决方案，如数据库镜像、故障转移集群等。这些技术可以确保在硬件故障、软件故障或其他意外情况下，数据库系统能够持续运行，保证业务的连续性。支持数据备份和恢复功能，可以定期对数据库进行备份，并在需要时快速恢复数据。这对于保护企业的重要数据至关重要。安全性：提供强大的安全功能，包括用户身份验证、访问控制、数据加密等。可以对不同的用户和角色设置不同的访问权限，确保数据的安全性和保密性。支持透明数据加密（T DE）等高级加密技术，可以对整个数据库进行加密，防止数据泄露。集成性和扩展性：与微软的其他产品和技术紧密集成，如 Windows Server、Visual Studio 等。这使得开发人员和管理员能够更加方便地进行开发、部署和管理。提供丰富的扩展功能和接口，可以与第三方软件和工具进行集成。例如，可以通过 O D B C、J D BC 等接口与其他编程语言和数据库系统进行交互。

二、应用场景

企业资源规划（E R P）系统：SQL Server 可以作为 E R P 系统的后端数据库，存储和管理企业的各种业务数据，如销售订单、库存信息、财务数据等。通过与 E R P 软件的集成，可以实现高效的数据处理和业务流程管理。客户关系管理（C R M）系统：用于存储客户信息、销售机会、客户服务记录等数据。通过强大的查询和分析功能，可以帮助企业更好地了解客户需求，提高客户满意度和销售业绩。电子商务平台：管理商品信息、订单数据、用户信息等。支持高并发的访问请求，确保电子商务平台的稳定运行。数据分析和报表：作为数据仓库的后端存储，支持大规模的数据存储和分析。可以使用 SQL Server 的分析服务和报表服务，创建各种数据分析报表和仪表盘，为企业决策提供数据支持。

三、优势与不足

优势：功能强大：提供了丰富的功能和工具，满足企业级应用的各种需求。易于使用：与微软的其他产品和技术具有良好的集成性，使得开发人员和管理员能够快速上手。高可用性和可靠性：通过多种技术保障数据库系统的持续运行。安全性高：提供了多层次的安全防护措施，保护企业数据的安全。不足：成本较高：对于小型企业来说，可能需要较高的成本投入。对硬件要求较高：在处理大规模数据时，可能需要较高配置的硬件设备。

总之，SQL Server 是一款功能强大、可靠安全的关系型数据库管理系统，适用于各种规模的企业应用。在选择数据库管理系统时，企业需要根据自身的业务需求、预算和技术实力等因素进行综合考虑。
