GPG and git on macOS

Setup

No need for homebrew or anything like that. Works with https://www.git-tower.com and the command line.

Install https://gpgtools.org -- I'd suggest to do a customized install and deselect GPGMail.
Create or import a key -- see below for https://keybase.io
Run gpg --list-secret-keys and look for sec, use the key ID for the next step
Configure git to use GPG -- replace the key with the one from gpg --list-secret-keys

Hyperlinks (a.k.a. HTML-like anchors) in terminal emulators

[ Update 2025-03-24: Commenting is disabled permanently. Previous comments are archived at web.archive.org. ]

Most of the terminal emulators auto-detect when a URL appears onscreen and allow to conveniently open them (e.g. via Ctrl+click or Cmd+click, or the right click menu).

It was, however, not possible until now for arbitrary text to point to URLs, just as on webpages.

HOWTO: Create Your Own Self-Signed Certificate with Subject Alternative Names Using OpenSSL in Ubuntu Bash for Window

Overview

My main development workstation is a Windows 10 machine, so we'll approach this from that viewpoint.

Recently, Google Chrome started giving me a warning when I open a site that uses https and self-signed certificate on my local development machine due to some SSL certificate issues like the one below:

I've been working with Apache Kafka for over 7 years. I inevitably find myself doing the same set of activities while I'm developing or working with someone else's system. Here's a set of Kafka productivity hacks for doing a few things way faster than you're probably doing them now. 🔥

Show me all my Kafka topics and their partitions, replicas, and consumers
Show me the contents of a topic
Create a Kafka topic
Produce messages to a Kafka topic
Validate the schema of messages before producing to a topic
Do all of this at a distance

Opening in IJ

JMC with IntelliJ

At this stage there’s two approach:

If you only need to work on the core libraries, then you only need those, and they can be imported as a maven project with some configuration
If you need the full blown JMC, then you need the other import approach, that is a mix of .project - .classpath and Maven projects.

Working on the on the `core` libraries

File | Open… , then select the core folder in the JMC cloned repository,
Trust the project (also tick the Trust projects in <JMC clone path> as well)

	// Adapted to create a "drop it in and watch it work" approach by Nikhil Jha.
	// Just add your package statement and drop it in the folder with all your other classes.

	It is imperitive that you need to change 2 files in order to prevent transmission to overwrite your changes.
	The default credential is admin:admin

	1. SSH into your synology
	2. edit /var/packages/transmission/target/var/settings.json to change the username and password
	3. edit /var/packages/transmission/var/settings.json to change the username and password

	To understand how the username and password get inserted into the settings.json, you can read /var/packages/transmission/scripts/service-setup
