Diskplorer - disk latency/bandwidth grapher

Diskplorer is a small set of tools around fio that can be used to discover disk read latency at different read and write workloads. Diskplorer runs a matrix of 21 write workloads (0% to 100% of the maximum bandwidth, in 5% increments) and 21 read workloads (0% to 100% of the maximum IOPS, in 5% increments) for a total of 441 different workloads. The disk is fully written first in order to eliminate clean-disk effects.

Many Kubernetes users liked Lens (or even still do). After it became not Open Source and Lens ID was introduced, many switched to OpenLens. Unfortunately, that fork did not last long and hasn’t issued any releases since July 2023. However, it turned out to be another fork, which is currently active: Freelens.

This project started around January of this year, and released its v1.0.0 in February and further v1.1.0 just five days ago. Today, Freelens:

- is fully compatible with the latest Kubernetes version (1.32);
- comes with kubectl v1.32.3 and Helm v3.17.2;
- is based on Electron 34.3.3 with Node 20.18.3 and Chrome 132.0.6834.210;
- requires GNU C Library 2.34+ for Linux (i.e. Debian 12, Ubuntu 22.04, Fedora 35, openSUSE Leap 15.4), macOS 11+ or Windows 10+ to run.

About 5 hours ago, Apple released a Swift package (Containerization) and a CLI tool (container) to easily run Linux containers on Mac computers.

Containerization uses Virtualization.framework on Apple silicon to provide APIs to spawn lightweight virtual machines and manage their runtime environment, manage OCI images, interact with remote registries, etc. It relies on vmnet framework for managing the virtual network to which the containers attach.

container is a user-facing tool for creating and running Linux containers as lightweight virtual machines. It works with OCI-compliant container images, allowing you to interact with common container registries. Using it, you can also configure memory and CPU limitations for containers, build and run multiplatform images, share host files with containers, view container and system logs.

Both projects are available as Open Source (Apache 2 license). More details about them:
