Vim has a Terminal Mode!

Since v8.1 (May 2018), Vim has shipped with a built-in terminal. See https://vimhelp.org/terminal.txt.html or type :help terminal for more info.

Why use this? Mainly because it saves you jumping to a separate terminal window. You can also use Vim commands to manipulate a shell session and easily transfer clipboard content between the terminal and files you're working on.

To Display the current git commit hash execute the following snipped:

git rev-parse --short HEAD

To Extract this to use in a Jenkinsfile use the sh function with the script and returnStdout parameter set to true:

def commitHash = sh(script: 'git rev-parse --short HEAD', returnStdout: true)

Overview

The [MySQL Input Plugin][8] for Telegraf gathers data from a MySQL server.

For connections that are local to the MySQL server, use localhost as your hostname:

# By default, Docker containers run as the root user. This is bad because:
#   1) You're more likely to modify up settings that you shouldn't be
#   2) If an attacker gets access to your container - well, that's bad if they're root.
# Here's how you can run change a Docker container to run as a non-root user

## CREATE APP USER ##

# Create the home directory for the new app user.
RUN mkdir -p /home/app

This was performed on Ubuntu 14.04 with a fresh install of PostgreSQL 9.3.14 directly from the official Postgres apt repo. It only works if the query planner chooses the attached plan (with HashAggregate).

Create and populate a new database:

psql -U postgres -c "create database test;"
psql -U postgres test < populate.sql

Open a connection to the database and execute query.sql. The Postgres worker memory usage will rise approximately 50MB and won't be released until the connection is closed.

The easiest way to start using the LLVM C++ API by example is to have LLVM generate the API usage for a given code sample. In this example it will emit the code required to rebuild the test.c sample by using LLVM:

$ clang -c -emit-llvm test.c -o test.ll
$ llc -march=cpp test.ll -o test.cpp
