#284Looking for a job and trying to get clients for my new security consulting startup. May start up a local malware cleaning service, but I don't think I'll get any clients since I can't afford a storefront and there's a few small computer repair stores near me. I live in a rural part of Louisiana, so yeah idk.

#285I'm experimenting/prototyping 3D models to passively absorb specific low frequencies, with the idea of reducing fatigue/increasing productivity in the workplace (where making/taking calls is continuous). The 3D models are based off of a research paper by Yong Li and Badreddine M. Assouar, called "Acoustic metasurface-based perfect absorber with deep subwavelength thickness" [0]. Absorbing low (male voice; 80Hz - 300H…
Naive question but what would be the advantage over traditional sound isolation? (such as in music studios)

#286Working on https://ts.coach , a free guide to Typescript that runs entirely in the browser.
I'm sure you're familiar, but just in case: https://totaltypescript.com does a phenomenal job in this space -- esp. its VSCode extension, which acts as an interactive linter.

#289I've been building for some time a local production like environment running in Minikube, deployed in a single `terraform apply` command. The plan is to deploy in one command a couple of home made services, frontend, backend, some websockets in between, and have everything accessible over HTTPS via Ingress resources. That, and all the open source observability tools you can imagine (Grafana/Prometheus/Loki/Tempo), configured and running at once.
See https://github.com/chazapp/o11y.
These last few days I have decided to try getting Kubernetes Gateway API to work, using the implementation of Istio. I have written an `auth` microservices which provides JWTs and published a public JWKS endpoint, and intend to have the API gateway validate tokens and claims to allow access to other services. The plan being to write API services without any knowledge of the authentication systems that happen upstream. If a request reaches them, it's that it had been validated before !
