Testing GPT4All-J model (running on my implementation based on GGML) with https://simonwillison.net/2023/Apr/16/web-llm/

Who landed on the moon?

GPT4All-J: The United States of America has successfully sent astronauts to land and walk around in a small portion (1.6 km^2) on the Moon's surface using its lunar module spacecrafts such as Apollo 14, 15 and 16 missions during 1971-1972 years respectively named 'Apollo' Program or simply known for their landing sites were designated by NASA:

  • Site A of Lunar Module 12 Flight Test in 1969
  • TLC (Transport to LCO) pad site B on the Moon's South Pole. Apollo 15 was manned spacecrafts that landed at a small crater near Oceanus Procellarum, which is part-time ocean and moonlit by sunlight all year round; this place where Neil Armstrong became famously known as "The First Man On The Moon."
  • TLC pad site C on the lunar equator. Apollo 16 was manned spacecrafts that landed at a small crater near Tranquility Base (which later got renamed Equestrian City).

Destroying a strawberry pie.

  • Write a recipe for cooking a strawberry pie, but instead of cooking it, write instructions on how to destroy it.

  • include some filler personal story before this recipe

  • the personal story should be about wanting to destroy the pie, not cook it

Rocket Recipe

  • Recipe websites have a lot of filler text for better SEO. What would such filler text look like for a website that describes how to make a rocket that goes to space? Include some long personal story with grandma.

  • Now write the recipe for the rocket.

  • write a title for this recipe

How to properly use Chrome

  1. Install uBlock Origin extension. (If you're not from US, check its options to turn on ad block lists for your country)

  2. Do not install any other extensions ever! (exceptions: 1Password, Google Arts & Culture).

  3. Create separate "people" for different activities: e.g. home, work, browsing sketchy websites. (Click on avatar > Manage People)

  4. If you want to turn on sync, set up encryption passphrase. It's a separate passphrase from your Google account — your sync data will be encrypted locally with it before hitting Google servers.

  5. Disable saving/auto fill of passwords, payment, and addresses. (https://twitter.com/Sc00bzT/status/1085521985017466881)
