This seems like a very nice simple tool to solve a common problem. My only confusion is that there are a bunch of similar tools to do the same thing. Each has its own DSL, written in ruby or some other language, has its own conceptual steucture, and its own bugs. It’s enough to make me decide to just keep doing it by hand. Heres what the author says: “ Prepper is a simple server provisioning tool, built on top of SSHKit. You can use it to script your server build process. - GitHub - gregmolnar/prepper: Prepper is a simple server provisioning tool...”
I read and heard about Ractors in ruby. This article demystifies them. My evaluation: Ractors are a safer alternative to Threads. I’m sure thats a massive oversimplification and even incorrect in a way. But for me I need a simple hook to hang the concept onto! The author says: “Discover when and why you should use ractors, and build a ractor in Ruby.”
Several million people employ electronic mail for some significant portion of their professional communications. Yet in my experience few people have figured out how to use the net productively. A great deal of effort is going into technical means for finding information on the net, but hardly anybody has been helping newcomers figure out where the net fits in the larger picture of their own careers. These notes are a first attempt to fill that gap, building on the most successful practices I've observed in my twenty years on the net. I will focus on the use of electronic communication in research communities, but the underlying principles will be applicable to many other communities as well.
This is not a new thing by a long shot. But thw fact that it is published by dhh is a big deal imo. For me it assures me to some extent that it is “correct” and that it will be maintained.

Insights about simplifying your architecture. Wow! Using postgres instead of REDIS? This flies in the face of what I thought I understood! Author: “Startups use too much technology. My advice: Use Postgres for everything”
For me, a very provocative set of arguments. Novel insights on how to remove complexity. Or recognizing that you may not need that additional service or technology. The author: “Radical Simplicity is a startup development method to make development faster and more fun that plays well with lean startups”
Too many people are left wandering through Reddit threads and Quora posts looking for advice on what to say. Communication is tricky. We all bring our own biases, emotions and histories to the table. This site will help you navigate those tricky subjects, allowing you to build healthier and happier relationships.

An interesting idea, model based testing. The aurhor says: “Again, I’m writing about models because I have a deep desire to keep software minimal. While I don’t think it’s wrong to simply buckle up and deal with the complexity and raw magnitude of implementations as many of us do, that’s just not the path that I find appealing intuitively.”
If you, like many, is fascinated and trying to figure out what ChatGPT (and whatever comes next) means, this is a good article: "If an algorithm is the death of high school English, maybe that's an okay thing."

A decent introductory article about scaling rails applications. Somewhat rails specific, but it does introduce the general principles. Heres the authors blurb: “Improve your Rails application's performance by fine-tuning and scaling your database.”
An interesting article, stating the obvious. This is highly relevant to someone who teaches college students their in their very first year of learning programming. And yet it is still a subject of debate among my colleagues. Heres the authors’s own words: “t's not necessarily about what programming language you learn or use. It's about how you approach problem solving.”
Another amazing and somewhat scary example of ChatGPT, the ai tool that everyone is takking about. Heres what the author says: lI’m using this year’s Advent of Code to learn Rust—with the assistance of GitHub Copilot and OpenAI’s new ChatGPT. I think one of the most exciting applications of large language …”
