How to setup Let's Encrypt for Nginx on Ubuntu 16.04 (including IPv6, HTTP/2 and A+ SLL rating)

There are two main modes to run the Let's Encrypt client (called Certbot):

Standalone: replaces the webserver to respond to ACME challenges
Webroot: needs your webserver to serve challenges from a known folder.

Webroot is better because it doesn't need to replace Nginx (to bind to port 80).

In the following, we're setting up mydomain.com. HTML is served from /var/www/mydomain, and challenges are served from /var/www/letsencrypt.

Define the child mapping for collection properties on the contact

CreateMap<ApSupplier, ApSupplierDto>();
CreateMap<PoSupplier, PoSupplierDto>();
CreateMap<Customer, CustomerDto>();
CreateMap<Salesperson, SalespersonDto>();

Map from UniVerse mv.NET Entity to DTO

.NET Core

Command line setup

dotnet new

dotnet restore

dotnet run

git push origin --delete branch-name

Handy notes from this article.

git submodule add https://github.com/caarlos0/shell-travis-build.git build
cp build/travis.yml.example .travis.yml

Adds ShellCheck verification via Travis CI for any shell scripts in the repo.

5 entertaining things you can find with the GitHub Search API

Let's have some command-line fun with curl, [jq][1], and the [new GitHub Search API][2].

Today we're looking for:

The hottest repositories created in the last week.
The oldest user accounts with zero followers. (So sad.)
Issue trends by language.
Clojure projects defying convention.

Use this code before performing a rolling restart of an Elasticsearch cluster. The transient field means that the setting will be reset the next time Elasticsearch is restarted on the node.

Disable

PUT /_cluster/settings
{
  "transient": {
    "cluster.routing.allocation.enable": "none"
 }

	Arq stores backup data in a format similar to that of the open-source version
	control system 'git'.

	Content-Addressable Storage
	---------------------------
	At the most basic level, Arq stores "blobs" using the SHA1 hash of the
	contents as the name, much like git. Because of this, each unique blob is only
	stored once. If 2 files on your system have the same contents, only 1 copy of
	the contents will be stored. If the contents of a file change, the SHA1 hash is
	different and the file is stored as a different blob.
