https://t.co/r6gwzo1zvS Hopefully this will help bridge the gap in the development process between algorithm coding and deployment to production.

Why is the Win32 API so separated from the C runtime (e.g. kernel32.dll provides ZeroMemory instead of memset)? Is it because Pascal's popularity early on meant that Microsoft didn't want to tie early versions of Windows to C?

[🔎Julia Evans🔍 @b0rk]

people sometimes ask me "julia, have you ever written a comic about X?". I have a search page where you can search (almost) all my comics: https://t.co/GG2PuZbxeg

it's just by title, not full text search yet

@mrclay_org @jpetazzo Thank-you. I had solved all my issues I listed, but I was letting the OP know what problems were not evident from a first pass of trying out Docker.

I wish I knew about ss years ago.

[Rakesh Jain @devops_tech]

SS -

ss command is a tool that is used for displaying network socket related information on a Linux system.

@jpetazzo If I have an application in a Docker container, how do I run it from the host environment in order to process data which is also in the host environment? What's the syntax? How does the container gain access to host data?

[Frederick Ollinger @codingequanimi2]

@jpetazzo Also, do you need to be in the same directory of a Dockerfile to run a container that has all ready been built? What's the difference between Dockerfile and docker-compose? Why would I use docker-compose?

[Frederick Ollinger @codingequanimi2]

@jpetazzo With Docker it was how to get a shell inside the container? Why was it just stopping as soon as it started? And how can a Docker container interact with my local file system? How can Docker be run as a shell script?

@b0rk Looks like another cartoon from our favorite tech cartoonist.

Facebook is down this morning, apparently due to a BGP problem.

What's BGP? It's an absolutely essential but fairly obscure internet protocol. I have a CS degree, but I only know about it because I did a summer internship with @Akamai a very long time ago.

A brief explainer:

@tony_bridges_el @cybergibbons I secure my seat with a bicycle chain and my wheels with anti-theft skewers. Last time a thief went after my bicycle, he only managed to cut off my bicycle light, and he slashed a tire in frustration.

[Cory House @housecor]

Handy pattern I enjoy: Clone the repo twice.

This way, I can have two local copies, pointed to different branches.

I find this is useful when I need to reference or review code in a different branch. I don't have to commit/stash my work-in-progress to do so. 😎

Any good books or articles on Hashicorp Vault? I'm specifically looking for how things get boot strapped in a deployment. How to automatically unlock in a secure manner? I have a chicken and egg feeling.

In Terraform, if you'd like to set a string in a Docker container with line breaks you need to use "bash -e" and wrap the string in single quotes. #Terraform #DevOps #bash #Linux

[Frederick Ollinger @codingequanimi2]

You may even inject variables such as: ${var.secret} inside the command string, and Terraform will pull the variable into the shell of the local-exec. It feels magical once you figure it out.
