ervinne13 / granite.sh

Created August 7, 2025 03:27

Wrapper for granite to automatically copy its output to clipboard

	#!/bin/sh

	BASE_PROMPT="You are a terminal-savvy assistant.
	When answering questions, always output the commands first, prefixed by RUN: and wrapped in backticks.
	Do not include RUN inside backticks, only the command. Explain everything but only after you list them out.
	I'll be reading the response with a script so it's imperative you list them with RUN: first.
	Prefer single commands as much as you can.
	For example you can output something like:

	RUN: `df -h`

A simple function that generates an unordered list based on a tree of nodes.

	project that has [JSDOM](https://github.com/jsdom/jsdom) to run it in the terminal.

	Requirements:
	A node is either a string, or a JS object of the form {"name": "a name", "nodes": [more, nodes]}

ervinne13 / your-app.conf

Created October 18, 2022 06:33

Blocking 413 errors in NGINX: What I usually see is that developers tend to increase the max upload size limit of nginx to absurd levels and handle the validation in the application. Why not block it here in NGINX right away?

	server {
	listen 80;
	server_name dev.your-app.com;

	server_tokens off;

	location / {
	return 301 https://$host$request_uri;

ervinne13 / date_range_overlap.py

Created September 21, 2022 02:24

Get # of days that overlap between two ranges. Usually use this to check if a date range falls within another, larger date range but might as well check for any overlap.

	from datetime import datetime
	from collections import namedtuple

	Range = namedtuple('Range', ['start', 'end'])

	# Returns a positive number of days overlapping, otherwise, returns 0
	def get_days_overlap(r1: Range, r2: Range) -> int:
	latest_start = max(r1.start, r2.start)
	earliest_end = min(r1.end, r2.end)

ervinne13 / csv_to_parquet.py

Last active April 19, 2022 10:05

A quick and easy CSV to Parquet converter from one bucket to another. This may be attached to a lambda function that can be triggered whenever a new s3:PutObject is executed.

	from io import BytesIO
	import boto3
	import pandas as pd
	from os import environ


	def convert(bucket, key):
	s3_client = boto3.client('s3', region_name=environ['REGION'])
	s3_object = s3_client.get_object(Bucket=bucket, Key=key)
