The single most valuable thing I've had cursor do is unfuck up homebrew postgres for me

searls / kamesame_synonym_detection.md
Created June 12, 2025 07:20
I kinda forgot how I implemented synonym detection in KameSame (other than to know it was the MAIN THING the app had to do and performantly), so I asked Cursor to explain it

Understanding KameSame synonym detection

Exported on 6/12/2025 at 16:19:24 GMT+9 from Cursor (1.0.0)

User

Explain how KameSame does synonym detection when a user answers a question with a valid response but not the one we're looking for. can you please produce a report explaining this at a conceptual level and then back it up with progressively deeper technical dives?

I remember that while this is driven through the UI, it runs all the way down to the design of the database views, which i believe i even materialized for speed so that every night when the dictionaries are updated the synonym query is faster. i'll need you to check me on that stuff though b/c it's been 6+ years since i did this. provide receipts!

Truncating content to fit into a tweet-like post without accidentally truncating in the middle of a URL or a hashtag is… not fun?

Use fswatch instead of the built-in hugo server, which keeps giving me too many file errors
#!/bin/bash
# Ensure fswatch is installed
if ! command -v fswatch &> /dev/null; then
echo "Installing fswatch with Homebrew..."
brew install fswatch
exit 1
fi
# Ensure Caddy is installed for serving files

There's no way for web developers to prevent 1Password from thinking it can fill one-time-passwords (OTP) if they have autocomplete=one-time-code. This is madness, because 80% of these are SMS/email, and 1Password offers no way to fill these.
import { Controller } from '@hotwired/stimulus'
const BANNED_NODES = ['com-1password-button', 'com-1password-menu']
export default class extends Controller {
connect () {
this.observer = new window.MutationObserver(mutations => {
mutations.forEach(mutation => {
mutation.addedNodes.forEach(node => {
if (BANNED_NODES.includes(node.nodeName.toLowerCase())) {
node.remove()

searls / resets_session_but_its_still_thursday_i_need_these.rb
Created August 15, 2024 12:28
Was genuinely surprised Rails `reset_session` doesn't accept a list of exceptions
# If you have any session variables that should survive a logout, add them to
# the except_for array. Usage from a controller:
#
# ResetsSessionButItsStillThursdayINeedThese.new.reset(self,
# except_for: [:has_logged_in_before])
class ResetsSessionButItsStillThursdayINeedThese
def reset(receiver, except_for: [])
backup = except_for.map { |key| [key, receiver.session[key]] }
receiver.reset_session

searls / fake_markdown.rb
Created July 16, 2024 14:52
I was disappointed with the faker gem's Markdown and Lorem modules, so I wrote a custom thing that produced realistic-length paragraphs with just enough markdown junk sprinkled in to know that it's rendering correctly in my app
require "faker"
def lorem_paragraphs
rand(2..4).times.map {
rand(4..6).times.map {
Faker::Lorem.sentence(word_count: rand(10..40))
}.join(" ")
}.join("\n\n")
end
