We are migrating from SQL Server Fail over Instance to Always On Availability group. The current network name is ABC\ABCTEST where ABC is the SQL server Virtual Name and ABCTEST is the named instance name. In always on availability group all the connection will make connection through the Listener name for example Listerner123 and itRead more
I came across the following inequality in one of my calculations ($ X,Y$ are centered random variables): $ $ \operatorname{E}(X^2Y^2)-\operatorname{E}(X^2)\operatorname{E}(Y^2) \geq 2 \operatorname{E}(XY)^2$ $ or, written in terms of covariances, $ $ \operatorname{Cov}(X^2,Y^2) \geq 2 \operatorname{Cov}(X,Y)$ $ . If $ (X,Y)=(U,V)$ is a two-dimensional centered Gaussian, this becomes an equality and if $ (X,Y)=(H_p(U),H_q(V))$ ,Read more
Generally I would always answer “yes” to this question, because at this point, your DI container has become a service locator, and you’re losing the benefits of DI. However, I wonder if it is acceptable in the following specific scenario. I have an application with a DI container. The DI container is responsible for constructingRead more
Let $ F$ be a infinite-dimensional complex Hilbert space, with inner product $ \langle\cdot\;| \;\cdot\rangle$ and the norm $ \|\cdot\|$ and let $ \mathcal{B}(F)$ be the algebra of all bounded linear operators on $ E$ . Let $ M\in \mathcal{B}(F)^+$ (i.e. $ \langle Mx\;, \;x\rangle\geq0$ for all $ x\in F$ ). Assume that $ M$Read more
I want to be able to retrieve a jsonb array of objects as a record set. Maintaining the order of objects is critical. Will jsonb_to_recordset always return the record set in the order of the array of objects?Read more
I am working on setting up a secondary copy of our prod DB for Data Warehousing and even something we can possibly use to offload other processes and reporting on. Basically just a read only copy of prod. Issues is, I am running into options that breaks our point in time backup strategies and thatRead more
In “The Theory of Matrices” by Gantmacher, Chapter II, section 4: Corollary $ 3$ : If $ S= ||s_{ik}||_1^n$ is a symmetric matrix of rank $ r$ and $ $ D_k= S\bigl( \begin{smallmatrix} 1 & 2 & \dots & k \ 1 & 2 & \dots & k \end{smallmatrix} \bigr)\ne 0 \ \ \ \Read more
Assume that $ X$ and $ Y$ are two arbitrary non-negative random variables with joint probability math function $ p(x,y)$ . Is the following inequality true for $ \alpha\geq 1$ ? \begin{align} \left(\mathbb{E}\left[X^\alpha\right]-\mathbb{E}\left[X\right]^\alpha\right)^{\frac{1}{\alpha}}+\left(\mathbb{E}\left[Y^\alpha\right]-\mathbb{E}\left[Y\right]^\alpha\right)^{\frac{1}{\alpha}}\geq \left(\mathbb{E}\left[(X+Y)^\alpha\right]-\left(\mathbb{E}\left[X+Y\right]\right)^\alpha\right)^{\frac{1}{\alpha}} \end{align}Read more
I’ve tried restarting, making sure “don’t keep activities is unchecked” and cleaning my cache. None of these have worked. In most cases when I toggle between open apps and when switching back it has to reset. Additionally, it has made it impossible to set up my Echo Dot because the Alexa app resets mid setup.Read more
