Why did you do this?

Relax, I only have one Sunday to work on idea, literally my weekend project. So I tried Deepseek to see if it can help. Surprisingly, it works and it saves me another weekend...

What is your setup?

Just chat.deepseek.com (cost = free) with prompts adapted from this gist.

Does it work in one-shot or I have to prompt it multiple times?

Chromium on Vercel (serverless)

This is an up-to-date guide on running Chromium in Vercel serverless functions in 2022. What you will read below is the result of two days of research, debugging, 100+ failed deployments, and a little bit of stress.

Getting started

Step 1: Install dependencies

Use chrome-aws-lambda that comes with Chromium pre-configured to run in serverless, and puppeteer-core due to the smaller size of Chromium distributive.

Xcode VIM

Learning VIM in Xcode comes with its own set of challenges and limitations, but there is enough there for you to give your mousing hand a break and master the keyboard.

A limited set of commands are available in Xcode, and this document attempts help ease the learning curve of using VIM in Xcode by providing a handy reference as well as what I find works for me in practice.

NOTE: Commands are case-sensitive. A command of N means pressing shift + n on the keyboard.

This document is a work in progress! Leave a comment if you would like to see a change.
