Precloud – Dynamic tests for infrastructure-as-code
Infrastructure as code (IaC) often fails during deployment due to dynamic constraints such as name collisions, quota limits and other resource-specific constraints that devs run halfway into an IaC deployment. We witnessed this first hand at TinyStacks and built precloud - an open-source framework to define and run dynamic tests before IaC deployments. The precloud framework currently supports Terraform and AWS CDK with several default checks (unique names, service quota checks and more) and ability to define your own!
In plain words
Precloud is an open-source framework that tests infrastructure-as-code before deployment to catch dynamic constraint failures like name collisions and quota limit violations. It supports Terraform and AWS CDK with built-in checks for common issues and the ability to define custom tests. Precloud helps developers identify problems early that would otherwise cause deployments to fail partway through execution.

This works suprisingly well. Just give it instructions like "make it winter" or "remove the cars" and the photo is altered. Here are some examples of transformations it can make: Golden gate bridge: https://raw.githubusercontent.com/brycedrennan/imaginAIry/ma...

I integrated this new InstructPix2Pix model into imaginAIry (python library) so it's easy to use for python developers.

The project is called QueryStorm. It uses Roslyn to offer C# (and VB.NET) support in Excel, as an alternative to VBA. I've posted about it before, but a lot has changed since then so figured I'd share an update. The current version includes a host of new features, namely a C# debugger, support for NuGet packages, and the ability to publish Excel extensions to an "AppStore" (which is essentially a NuGet repository). The AppStore can be used by anyone with the (free) runtime component. Another great addition is the community license, which is a free license for individuals and small companies…

Hey HN! Some more info: I’m an NHS doctor and the founder of Pi-A (https://www.pi-a.io) which developed Lungy (https://www.lungy.app). Lungy is an app (iOS only for now) that responds to breathing in real-time and was designed to make breathing exercises more engaging and beneficial to do. It hopefully has many aspects of interest to the HN community – real-time fluid, cloth and soft body sims running on the phone’s GPU. My background is as a junior surgical trainee and I started building Lungy in 2020 during the first COVID lockdown in London. During COVID, there were…
