Some of you are here, because you are interested in hiring me for a contract engagement. I know this, because I look at the analytics.

Next contract shall be

  • OUTSIDE IR35 or Statement of Work
  • Remote working for the foreseeable future
  • Contract rate £PRICE on application (SOW)
    • (In 2018-2019, in Central London, typical contract rates were £550 – £750 per day depending on the requirements and provided materials)
  • Or stupidly insane permanent salary from £101K base in the United Kingdom
  • Or by the way, I will be the technical lead or senior designer.

Other you can’t deal with that, then it is waste of yours and my time.

Carry on

As a platform engineer, I want to keep a copy of a my favourite Linux Bash Profile in my blog on the public web, so that I do not have to keep making it up from scratch every time I configure a Virtual Machine.

## MY FAVOURITE BASH PROFILE ~/.bash_profile
### Based of the

# Load workspace HTTP proxy configuration, if any
if [ -f ${HOME}/ ]; then

set -o emacs
# Do not exit on EOF. To exit the shell type `exit'
set -o ignoreeof
# Do not allow output redirection (>) to overwrite an existing file
set -o noclobber
# set the core limit
ulimit -c 10240

# As a platform engineer, I want to upgrade SHELL history to "remember long time"
set history=1024
set savehist=1024

That was my user story from last week.


I want to also share this BASH configuration in Home office and Work office situation. In work office, like you I work behind a HTTP Proxy so I extracted shell as an environment script to source-in.

## File: ~/
## set the proxy connections# set the proxy connections# set the proxy connections
#export HTTP_PROXY=''
#export HTTPS_PROXY=''
#export NO_PROXY="localhost,, 10.24*, *, *.corp"
#export http_proxy=${HTTP_PROXY}
#export https_proxy=${HTTPS_PROXY}
#export no_proxy=$NO_PROXY

Save this this shell source scripts as ${HOME}/ and then the file private to your user with the command: chmod 600 ${HOME}/

Have fun and enjoy your day.
