chi - Lightweight, idiomatic and composable router for building Go HTTP services
A lightweight, idiomatic and composable router for building Go HTTP services. It's especially good at helping you write large REST API services that are kept maintainable as your project grows and changes. chi is built on the new context package introduced in Go 1.7 to handle signaling, cancelation and request-scoped values across a handler chain.
The focus of the project has been to seek out an elegant and comfortable design for writing REST API servers, written during the development of the Pressly API service that powers our public API service, which in turn powers all of our client-side applications.

FullCalendar - JavaScript Event Calendar

Type Route - Flexible, type safe routing library
a flexible, type safe routing library built on top of the same core library that powers React Router.

esbuild - Extremely fast JavaScript bundler and minifier
A JavaScript bundler and minifier. It packages up JavaScript code for distribution on the web.

Why build another JavaScript build tool? The current build tools for the web are at least an order of magnitude slower than they should be. I'm hoping that this project serves as an "existence proof" that our JavaScript tooling can be much, much faster.

{CRD|ConfigMap}-based approach for lyfecycle management of various resources in Kubernetes and OpenShift. Using the Operator pattern, you can leverage the Kubernetes control loop and react on various events in the cluster. The idea of the operator patern is to encapsulate the operational knowledge into the abovementioned control loop and declarative approach.

Handshake - Decentralized naming and authority protocol
A decentralized, permissionless naming protocol where every peer is validating and in charge of managing the root DNS naming zone with the goal of creating an alternative to existing Certificate Authorities and naming systems. Names on the internet (top level domains, social networking handles, etc.) ultimately rely upon centralized actors with full control over a system which are relied upon to be honest, as they are vulnerable to hacking, censorship, and corruption. Handshake aims to experiment with new ways the internet can be more secure, resilient, and socially useful with a peer-to-peer system validated by the network's participants.
Handshake is an experiment which seeks to explore those new ways in which the necessary tools to build a more decentralized internet. Services on the internet have become more centralized beginning in the 1990s, but do not fulfill the original decentralized vision of the internet. Email became Gmail, usenet became reddit, blog replies became facebook and Medium, pingbacks became twitter, squid became Cloudflare, even gnutella became The Pirate Bay. Centralization exists because there is a need to manage spam, griefing, and sockpuppet/sybil attacks. Previous decentralized systems largely stopped working due to spam. If it were more costly to grief on the internet using decentralized systems, the need for trusted centralized corporations to manage these risks decrease. Internet services and platforms may benefit from building on top of a decentralized system which is specifically designed for resilience against sybil attacks.
As we may redecentralize.

Calling Bullshit.
The world is awash in bullshit. Politicians are unconstrained by facts. Science is conducted by press release. Higher education rewards bullshit over analytic thought. Startup culture elevates bullshit to high art. Advertisers wink conspiratorially and invite us to join them in seeing through all the bullshit — and take advantage of our lowered guard to bombard us with bullshit of the second order. The majority of administrative activity, whether in private business or the public sphere, seems to be little more than a sophisticated exercise in the combinatorial reassembly of bullshit.

We're sick of it. It's time to do something, and as educators, one constructive thing we know how to do is to teach people. So, the aim of this course is to help students navigate the bullshit-rich modern environment by identifying bullshit, seeing through it, and combating it with effective analysis and argument.

The Scrum at Scale Guide is the definitive guide to the Scrum@Scale framework. It contains the definitions of the components that make up the Scrum@Scale framework, including its scaled roles, scaled events, and enterprise artifacts, as well as the rules that bind them together.
Scrum, as originally outlined in the Scrum Guide, is a framework for developing, delivering, and sustaining complex products by a single team. Since its inception, it’s usage has extended to the creation of products, processes, services, and systems that require the efforts of multiple teams. Scrum@Scale was created to efficiently coordinate this new ecosystem of teams. It achieves this goal through setting up a “minimum viable bureaucracy” via a “scale-free” architecture.

Fabio - HTTP and TCP reverse proxy that is configured by Consul
An HTTP and TCP reverse proxy that configures itself with data from Consul.
Traditional load balancers and reverse proxies need to be configured with a config file. The configuration contains the hostnames and paths the proxy is forwarding to upstream services. This process can be automated with tools like consul-template that generate config files and trigger a reload.
Fabio works differently since it updates its routing table directly from the data stored in Consul as soon as there is a change and without restart or reloading.

Get a Kubernetes LoadBalancer where you never thought it was possible. In cloud-based Kubernetes solutions, Services can be exposed as type "LoadBalancer" and your cloud provider will provision a LoadBalancer and start routing traffic, in another word: you get ingress to your service.

inlets-operator brings that same experience to your local Kubernetes or k3s cluster (k3s/k3d/minikube/microk8s/Docker Desktop/KinD). The operator automates the creation of an inlets exit-node on public cloud, and runs the client as a Pod inside your cluster. Your Kubernetes Service will be updated with the public IP of the exit-node and you can start receiving incoming traffic immediately.
