Some questions about a special semiscalar product
Define the semiscalar product [x,y] by $ $ [x,y]=\inf_{t>0}\frac{1}{2t}[||x+ty||^2-||x||^2].$ $ E be an n.v.s. I donot know how to prove that 1.$ [x,\lambda x+\mu y]=\lambda||x||^2+\mu[x,y]\ \forall x,y\in E,\lambda\in\mathbb{R},\forall \mu >0.$ 2.$ [\lambda x,\mu y]=\lambda\mu[x,y],\forall x,y\in E,\forall\lambda,\mu\geq 0$ I probably understand that this semiscalar product is similar to an inner product, but I only have trigonometric […]

Currently I’m changing the light intensity or brightness "manually" with the _LightIntensity variable. But this shader applied to a material in a sprite renderer is not being affected by URP 2D lights, […]

Fluent-bit in Kubernetes cannot input timestamp data properly
At my company, I built a K8s cluster with Terraform and configured a logging system with EFK (Elasticsearch, Fluent-bit, Kibana). k8s and Elasticsearch use AWS’s EKS and Opensearch Servcie (ES 7.10), and Fluent-bit was installed separately as a Daemonset through Helm. https://artifacthub.io/packages/helm/fluent/fluent-bit In the case of Fluent-bit Config, it is structured as follows. config: inputs: […]
Data table fixed header & horizontal scroll – Angular
I’m working on a table that should have a fixed thead during page scrolling, and the table also needs to have a horizontal scroll.
