A distilled summary of Sam Altman's "How to Succeed with a Startup".

Sam Altman - How to Succeed with a Startup

Watch the full Y Combinator talk on YouTube from Aug 29, 2018 here: https://youtu.be/0lJKucu6HJc

Summary

  1. Build a product so good, people spontaneously tell their friends about it.
  2. Build a product that is easy to explain in a few words.
  3. Identify a market that is going to grow every year.
  4. A real trend is one where the early adopters use it obsessively.

A Node + TypeScript + ts-node + ESM experience that works.

The experience of using Node.JS with TypeScript, ts-node, and ESM is horrible.

There are countless guides of how to integrate them, but none of them seem to work.

Here's what worked for me.

Just add the following files and run npm run dev. You'll be good to go!

A (possible) fix for not being able to click around a webpage in Chrome on macOS.

Issue Description

After upgrading my MacBook Air M1 to macOS Sonoma 14.0 (not sure if it is related to this issue), I noticed that I often cannot click anything inside a webpage in Chrome, even though I can scroll the page.

Also, sometimes the navigation buttons don't work either.

Resolution Steps

It appears that this fix may have resolved the issue. The inspiration for this fix came from the following Apple community discussion thread:

Reusable bash functions.

Include the code below in any bash script!

This is a good way to start a bash script:

#!/usr/bin/env bash
set -eou pipefail

These are some useful generic reusable bash functions.

Validate fields from a package.json file.

You could use this code to, for example, validate fields from a package.json file for use in a Node.js CLI application.

It gives you a packageInfo object that has some useful fields that you could use (in a help or usage message, for example):

  • packageInfo.version, so that you can display the CLI version
  • packageInfo.bin, so that you can display the name of the CLI command
  • packageInfo.repository, so that you can display a URL to the repo for the CLI

Make sure your tsconfig.json includes "resolveJsonModule": true.

Here are some configuration settings for setting up Redis.

This should go in your docker-compose.yaml:

A Notion formula for calculating sprints.

Given a date field and a sprint size (10 days), this formula calculates the number of sprints remaining (integer) until the end of the year.

This formula can be used in a Notion formula field.

floor(max((dateBetween(dateAdd(dateAdd(start(prop("Date")), 11 - month(start(prop("Date"))), "months"), 31 - date(start(prop("Date"))), "days"), start(prop("Date")), "days") - dateBetween(end(prop("Date")), start(prop("Date")), "days")), 0) / 10)

Here's an explanation of what is going on:
