Markdown with PlantUML

How to use PlantUML with Markdown

PlantUML is a really awesome way to create diagrams by writing code instead of drawing and dragging visual elements. Markdown is a really nice documentation tool.

Here's how I combine the two, to create docs with embedded diagrams.

Step 0: Setup

Get the command-line PlantUML from the download page or your relevant package manager.

Modified from original to support both GET and POST, status code passthrough, header and form data passthrough.
Usage: http://hostname:port/p/(URL to be proxied, minus protocol)
For example: http://localhost:5000/p/www.google.com

Using cloud-init for cloudless provisioning of Raspberry Pi

Installing cloud-init on a fresh Raspbian Lite image

This is a work in Progress!

Purpose

This mainly demonstrates my goal of preparing a Raspberry Pi to be provisioned prior to its first boot. To do this I have chosen to use the same cloud-init that is the standard for provisioning servers at Amazon EC2, Microsoft Azure, OpenStack, etc.

I found this to be quite challenging because there is little information available for using cloud-init without a cloud. So, this project also servers as a demonstration for anyone on any version of Linux who may want to install from source, and/or use without a cloud. If you fall into that later group, you probably just want to read the code. It's bash so everything I do, you could also do at the command line. (Even the for loop.)

Be Careful with Table Driven Tests and t.Parallel()

Be Careful with Table Driven Tests and t.Parallel()

We Gophers, love table-driven-tests, it makes our unittesting structured, and makes it easy to add different test cases with ease.

Let’s create our table driven test, for convenience, I chose to use t.Log as the test function. Notice that we don't have any assertion in this test, it is not needed to for the demonstration.

Effective Modern CMake

Effective Modern CMake

Getting Started

For a brief user-level introduction to CMake, watch C++ Weekly, Episode 78, Intro to CMake by Jason Turner. LLVM’s CMake Primer provides a good high-level introduction to the CMake syntax. Go read it now.

After that, watch Mathieu Ropert’s CppCon 2017 talk Using Modern CMake Patterns to Enforce a Good Modular Design (slides). It provides a thorough explanation of what modern CMake is and why it is so much better than “old school” CMake. The modular design ideas in this talk are based on the book [Large-Scale C++ Software Design](https://www.amazon.de/Large-Scale-Soft

Split tunneling with openconnect - A guide on how to use openconnect to establish a vpn connection to an enterprise cisco anyconnect vpn endpoint with client side routing.

Introduction

The purpose of this short howto is to show you how to:

  • use openconnect [1] to connect to an enterprise cisco anyconnect endpoint
  • whilst minimizing the amount of traffic that your route through the vpn connection

Usually VPN administrators will puth the default route to the users, so that all user traffic is routed through the vpn connection. This is to address the various security concerns around compromised user computers bridging external internet traffic into the secure VPN network.

While the VPN administrator can push routes to the clients, the client can ignore these default routes and establish client side routing so that only the required A.B.C.D/E network is routed through the VPN. All other traffic will still use the clients default route and default outbound internet connection.

Story: Writing Scripts with Go

Story: Writing Scripts with Go

This is a story about how I tried to use Go for scripting. In this story, I’ll discuss the need for a Go script, how we would expect it to behave and the possible implementations; During the discussion I’ll deep dive to scripts, shells, and shebangs. Finally, we’ll discuss solutions that will make Go scripts work.

Why Go is good for scripting?

While python and bash are popular scripting languages, C, C++ and Java are not used for scripts at all, and some languages are somewhere in between.
