Envirobly.com is a startup I solo founded and launched in October 2025. It’s a culmination of an intense 3 year work, crafting a platform to deploy web applications to, while keeping the costs manageable.

It runs the full lifecycle of application infrastructure on AWS. It connects to a customer’s AWS account, lays down regional foundations (VPC, NAT, Traefik gateways, Route53 DNS, Managed Prometheus), and lets teams ship services, databases, and gateways with zero-downtime deploys, live logs and metrics.

On my Intel iMac on macOS Ventura 13.4 I ran into this annoying issue when reinstalling the same version of Ruby (3.2.2 for example) with rbenv. When running rails test:system the firewall’s “Accept incoming connections” dialog would pop every time, no matter whether you Denied or Allowed the connection to go through previously, making testing quite painful.

I just noticed that on the latest MacOS Ventura 13.3.1 with Safari 16.4, the navigator.clipboard API is not accessible under plain HTTP .test domains, used with puma-dev for example. It returns “property is undefined” type of error.

I encountered the issue of a grayed out folder that can’t be deleted, in MacOS Mail app today. The discussion on Apple’s forums does not provide any actionable answers. After a while I figured out a solution myself and it’s very simple:
