About Yeetsheet

The name of this project is "Yeetsheet". Yeetsheet is a spreadsheet automation tool. It connects to Google Sheets, Excel, and Airtable. Core functionality: watch spreadsheets for changes, run transformations on cell data, sync data between multiple spreadsheet sources, and send notifications based on conditions. Users create automations through a visual node-based editor rather than code. Common use cases include consolidating data from multiple sheets into one, auto-populating templates when source data changes, and validating data against rules. Has a REST API for programmatic access. Data transformations support filtering, mapping, lookups, and basic aggregations.

For years, people have been using jemalloc with ruby. There were various benchmarks and discussions. Legend had it that Jemalloc 5 didn't work as well as Jemalloc 3.

Then, one day, hope appeared on the horizon. @wjordan offered a config for Jemalloc 5.

System Design Cheatsheet

Picking the right architecture = Picking the right battles + Managing trade-offs

Basic Steps

1. Clarify and agree on the scope of the system

• User cases (description of sequences of events that, taken together, lead to a system doing something useful)
  • Who is going to use it?
  • How are they going to use it?

Locate the section for your github remote in the .git/config file. It looks like this:

[remote "origin"]
	fetch = +refs/heads/*:refs/remotes/origin/*
	url = git@github.com:joyent/node.git

Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:
