Watch the breakdown here in a Q4 2024 prompt engineering update video

LLM library

Ollama

Level 1: Ad hoc prompt

Quick, natural language prompts for rapid prototyping
Perfect for exploring model capabilities and behaviors

Build image

docker build --tag <image tag>

Run container exposing port 4444 and mounting /views directory

docker run -p 4444:4444 /${PWD}/views:/code/views <image tag>

List running containers

If you have multiple applications on Heroku and would like to use a single Logentries account for all of them, this is how you do it. Basically, do not use add-ons, and send all drains to your account.

In your Logentries account, click on Add Log
Select Manual
In the form that appears, input the following:
- Log Name: access.log
- Select Set: new set named myapp-{environment}, for instance myapp-staging (at least, this is how I like to name my entries)
- Select the Plain TCP, UDP - logs are sent via syslog option
Click on Create Log Token

RecyclerView item onClick

RecyclerView does not have an OnItemClickListener like it's predecessor, ListView. However, detecting item clicks is pretty simple.

Set an OnClickListener in your ViewHolder creation:

private class MyAdapter extends RecyclerView.Adapter<MyAdapter.ViewHolder>  {

    public static class ViewHolder extends RecyclerView.ViewHolder

	const fetch = require('node-fetch')
	const am = require('am')

	async function main() {
	const url = 'https://www.example.com'
	const response = await fetch(url)
	const responseHeaders = Object.fromEntries(resp.headers.entries())
	console.dir(responseHeaders)
	return responseHeaders
	}

	#!/bin/bash

	# Define variables
	DOMAIN=foo.example.com

	# renew cert
	certbot renew

	# combine latest letsencrypt files for mongo
