NGINX Ingress Controller
NGINX Ingress Controller for Kubernetes
ingress-nginx is an Ingress controller for Kubernetes using NGINX as a reverse proxy and load balancer. It is built around the Kubernetes Ingress resource, using a ConfigMap to store the NGINX configuration. The goal of this Ingress controller is the assembly of a configuration file (nginx.conf). The main implication of this requirement is the need to reload NGINX after any change in the configuration file. Though it is important to note that we don't reload Nginx on changes that impact only an upstream configuration (i.e Endpoints change when you deploy your app). We use lua-nginx-module to achieve this. Check below to learn more about how it's done. Usually, a Kubernetes Controller utilizes the synchronization loop pattern to check if the desired state in the controller is updated or a change is required. To this purpose, we need to build a model using different objects from the cluster, in particular (in no special order) Ingresses, Services, Endpoints, Secrets, and Configmaps. -

Rofi
A window switcher, application launcher and dmenu replacement
Rofi started as a clone of the simple switcher, written by Sean Pringle - a popup window switcher roughly based on a super switcher. Simpleswitcher laid the foundations, and therefore Sean Pringle deserves most of the credit for this tool. Rofi (renamed, as it lost the simple property) has been extended with extra features, like an application launcher and ssh-launcher, and can act as a drop-in menu replacement, making it a very versatile tool. Rofi, like dmenu, will provide the user with a textual list of options where one or more can be selected. This can either be running an application, selecting a window, or options provided by an external script. It's not an application that can support every possible use case. It tries to be generic enough to be usable by everybody. Rofi has several built-in modes implementing common use cases and can be extended by scripts (either called from Rofi or calling Rofi) or plugins. -

Serverless Offline
Emulate AWS λ and API Gateway locally
This Serverless plugin emulates AWS λ and API Gateway on your local machine to speed up your development cycles. To do so, it starts an HTTP server that handles the request's lifecycle like APIG does and invokes your handlers. Options passed on the command line override YAML options. List of available function names and their corresponding serverless.yml function keys are listed after the server starts. This is important if you use a custom naming scheme for your functions as serverless-offline will use your custom name. The left side is the function's key in your serverless.yml and the right side is the function name that is used to call the function externally such as aws-sdk. Once you run a function that boots up the Docker container, it'll look through the layers for that function, download them in order to your layers folder, and save a hash of your layers so it can be re-used in future. -

Snappy
A fast compressor/decompressor
Snappy is a compression/decompression library. It does not aim for maximum compression, or compatibility with any other compression library; instead, it aims for very high speeds and reasonable compression. For instance, compared to the fastest mode of zlib, Snappy is an order of magnitude faster for most inputs, but the resulting compressed files are anywhere from 20% to 100% bigger. Snappy is intended to be fast. On a single core of a Core i7 processor in 64-bit mode, it compresses at about 250 MB/sec or more and decompresses at about 500 MB/sec or more. (These numbers are for the slowest inputs in our benchmark suite; others are much faster.) In our tests, Snappy usually is faster than algorithms in the same class (e.g. LZO, LZF, QuickLZ, etc.) while achieving comparable compression ratios. -
