Updating ycm_core with pyenv

The problem I had was how to update ycm_core when it is out of date.

Using pyenv and pyenv virtualenv

Linux 20.04 box with build deps installed:

apt-get -y install build-essential cmake vim python3-dev

ycm installed with: Vundle

Bash function to export aws credentials into environment

Using aws named profiles allow export using a bash function:

# Allow user to set aws profile in env
# requires aws and jq
# assume working role
awr() {
   if [ -x "$(command -v jq)" ] && [ -x "$(command -v aws)" ]; then
       export AWS_PROFILE=$1
 echo -n "Assumed working role: "

Open ssl commands I use from time to time

Shamelessly borrowed from the internets

General OpenSSL Commands

These commands allow you to generate CSRs, Certificates, Private Keys and do other miscellaneous tasks.

Generate a new private key and Certificate Signing Request openssl req -out CSR.csr -new -newkey rsa:2048 -nodes -keyout privateKey.key

Generate a self-signed certificate openssl req -x509 -sha256 -nodes -days 365 -newkey rsa:2048 -keyout privateKey.key -out certificate.crt

Error saving credentials: error storing credentials - err: exit status 1, out: `User interaction is not allowed.`

Error when remote on OSX cli and running docker commands for aws login or other login

Issue is that the cli lacks access to the keychain

aws ecr get-login-password --region us-west-2 | docker login --username AWS --password-stdin 123456789112.dkr.ecr.us-west-2.amazonaws.com
Error saving credentials: error storing credentials - err: exit status 1, out: `User interaction is not allowed.`

Fix with:
