Owner: Brian Vaughn

As of facebook/react/pull/22760, the experimental Test Selector API is now available in the experimental release channel.

To test the API, first install the experimental release:

What's the best way to answer the question "true or false?" in JavaScript

JavaScript does not bother you too much with types (at first), which is both a blessing and a cure. But we all know the Boolean type. Boolean variables can either be true or false. Yes or no.

Every value in JavaScript can be translated into a boolean, true or false. Values that translate to true are truthy, values that translate to false are falsy. Simple.

This is about two ways to make that translation.

First Things First

Enable PPA

 sudo apt update

Install apt-fast [Yes! it's really fast]

tmux cheat sheet

Prefix key

The default prefix is C-b. If you (or your muscle memory) prefer C-a, you need to add this to ~/.tmux.conf:

remap prefix to Control + a

	import json
	import os
	import ollama


	def query_ollama(prompt, model='openhermes:7b-mistral-v2.5-q6_K', context=''):
	response = ollama.generate(
	model=model,
	prompt=context + prompt)
	return response['response'].strip()

	# Jester: 0.2.1
	# Using Jester >= 0.3.0 is preferrable if your Nim version > 0.18.0
	# In case you're using Jester >= 0.3.0, look the syntax different
	# in its example because it's not backward compatible

	import db_sqlite, asyncdispatch, json, strformat, strutils, sequtils

	import jester
