Git Commit Freeze Due to GPG Lock Issues

If you encounter a problem where you cannot commit changes in Git – neither through the terminal nor via the GitHub Desktop application – the issue might be a freeze during the Git commit process. This is often caused by GPG lock issues. Below is a concise and step-by-step guide to resolve this problem.

Solution Steps

1. Check for GPG Lock Messages

Open your terminal and try to perform a GPG operation (like signing a test message). If you see repeated messages like gpg: waiting for lock (held by [process_id]) ..., it indicates a lock issue.

Semantic Versioning for IAC - `iacver`

When it comes to Infrastructure As Code, the software versioning system known as Semantic Versioning (semver.org) works from an API perspective but falls short elsewhere.

In short a semver is broken down into three "octets" and optional, additional information tagged to the end. Here are a few examples: v1.0.1, v3.1.1, v1.15.0-4. Each of these is a valid semver.

If we take the first example - v1.0.1 - and change the first octet, 1, to 2, we're saying the following:

There has been a change to this code and that change is not compatible with how you're using v1.0.1. The change is a breaking change. You should take care to introduce version v2.0.0 into your code or your environment.

Circumventing Deep Packet Inspection with Socat and rot13

I have a Linux virtual machine inside a customer's private network. For security, this VM is reachable only via VPN + Citrix + Windows + a Windows SSH client (eg PuTTY). I am tasked to ensure this Citrix design is secure, and users can not access their Linux VM's or other resources on the internal private network in any way outside of using Citrix.

The VM can access the internet. This task should be easy. The VM's internet gateway allows it to connect anywhere on the internet to TCP ports 80, 443, and 8090 only. Connecting to an internet bastion box on one of these ports works and I can send and receive clear text data using netcat. I plan to use good old SSH, listening on tcp/8090 on the bastion, with a reverse port forward configured to expose sshd on the VM to the public, to show their Citrix gateway can be circumvented.

Rejected by Deep Packet Inspection

I hit an immediate snag. The moment I try to establish an SSH or SSL connection over o

Example Git Branching Diagram

You can use this diagram as a template to create your own git branching diagrams. Here's how:

Create a new diagram with diagrams.net (formerly draw.io)
Go to File > Open From > URL
Insert this url (it points to the xml data below): https://gist.githubusercontent.com/bryanbraun/8c93e154a93a08794291df1fcdce6918/raw/bf563eb36c3623bb9e7e1faae349c5da802f9fed/template-data.xml
