Project Description

Terraform's remote backend requires a Terraform Cloud account and has an initial limited offering. While the initial offering is suitable for small resource management and teams this quickly becomes an issue as usage demands increase. In addition Terraform's remote operations (plan,apply, etc) are executed on HashiCorp's cloud resources which present issues for sensitive data such as passwords and access keys. Users are also constrained to as what tooling is available on the remote execution environment for example having kubectl as part of a local-resource. This project aims to address these shortcomings in a native Kubernetes implementation.

Bisection is a well known method of localizing which commit caused a regression in a code repository. git-bisect is a particularly used tool for this problem in git repositories. However it is often the case that the failure is probabilistic in nature - either because we don't have a reliable reproducer of the failure and thus not reproducing a problem on a particular commit does not mean the problem is not still present there, or because of inherent variability of e.g. performance regressions. Bisection for such failures is problematic as it takes only one false result for the bisection to end up in an unrelated part of code history. So in these cases we usually have to heavily extend runtime of a reproducer or do multiple test runs or multiple bisection runs to minimize a chance of error.

Project Description

I plan to learn how to program for PREEMPT-RT (Real Time) patched Linux kernel on aarch64 architecture. I will use a digital oscilloscope and a raspberry pi to compare preempt vs preempt-rt kernels on aarch64 vs a micro-controller. I then plan to build a 4WD robot utilizing the Raspberry Pi, I2C sonar sensors, DC motor controller and camera.
