Here’s a brief Scala ZIO HTTP “Hello, world” example from that repository, followed by a description of the code and “key points” to know about the example:

import zio.*
import zio.http.*

object HelloWorld extends ZIOAppDefault:

    // responds with plain text
    val homeRoute =
        Method.GET / Root -> handler(Response.text("Hello, World!"))

    // responds with JSON
    val jsonRoute =
        Method.GET / "json" -> handler(Response.json("""{"greetings": "Hello World!"}"""))

    // create HTTP route
    val app = Routes(homeRoute, jsonRoute)

    // run it like any simple app
    override val run = Server.serve(app)
                             .provide(Server.default)

October 26, 2019, in a meditative state:

As I return from the blackness of meditation, I see a very old man with long white hair and long white beard sitting in front of me. He’s wearing a full-body length white garment that I would call a dress if a woman was wearing it. (The garment has another name that I don’t know.)

He’s seated in a full-lotus position, with his eyes closed. I admire his posture, with one foot on each thigh, one hand resting on the other in a mudra in his lap, his shoulders back, and his chin tucked.

Not knowing what to do of whether he even speaks English, I whisper, “Hello.”

His eyes open gently, and he looks at me with a small, pleasant smile. “Welcome,” he replies.

In 2024, assuming that you’re using (a) a modern macOS version and (b) a modern Java version, and (c) you want to bundle a Java/JAR file as a Mac/macOS application, then (d) you’ll want to use the Java jpackage command to bundle your Java/Scala/Kotlin/JVM application into something that works like a native application. Here’s a quick example that works with the following assumptions:

In a previous post I wrote that True Christian Voters should trust the Bible, Jesus, and themselves, and today I want to get into a topic that has made me so upset that I’ve started writing about these things: That we — Christian voters — need to start voting for people who REALLY tell the truth, and SHOULD NOT vote for people who blatantly lie.

If you can’t tell from that paragraph, I’m sick and tired of politicians and television shows trying to co-opt Jesus’s message for their gain. I hope you agree that this needs to stop, and that people who constantly like are ANTI-CHRISTIAN.

What Jesus said about telling the truth

To begin with, let’s look at what Jesus said about telling the truth, and how we should not lie.

A few years ago a Christian friend asked me, “Do you think I’ll go to hell if I vote for Donald Trump?”

I had to think about that for a little while, and my first response was, “I don’t think any mortal human being is qualified to answer that question,” and then I followed that up with, “But, if you’re even asking that question, you’re obviously concerned that you will go to hell if you vote for Trump, and I can guarantee you from my own experience, that will be something you will think about when you are dying. So if you’re at all concerned about it, I wouldn’t do it.”

I know a little about being on a death bed

As I have written here many times now, it drives me crazy when politicians wave a Bible in one hand while simultaneously violating The Ten Commandments with the other. As a result, I started writing a series of articles on Christianity and being a “Christian Voter” in 2024.

The teachings of Jesus Christ

I started by writing about Jesus’s teachings, and in these times where the super-wealthy people are trying to buy votes, how you should ONLY trust in Jesus and The Bible:

• Fellow 2024 Christian Voters: Trust The Bible, Jesus, and yourself
• Quotes from Jesus about lying, and people who lie
• Christian Voters: Support Jesus’s values when voting (and don’t sell your soul and burn in hell)
• Christian Voting 2024: The top principles Jesus Christ taught

Mindfulness/meditation FAQ: What are the reasons, purposes, or motivations to practice mindfulness and meditation?

The motivations to meditate

I just took a little time to share some old notes from my meditation practice about “The purpose of mindfulness.” (This is also stated in other ways, like “Why bother being mindful?”, or, “What are the motivations for practicing mindfulness and meditation?”)

In the following sections I describe the purposes and motivations for practicing both mindfulness and meditation.

Before getting into my notes, I don’t know how many people know Ram Dass or have read his writings, but I updated the first motivation here based on his work, because if you really get into mindfulness and meditation, what he states is the end goal.
