Summary of BRC-100: Wallet Standard for Bitcoin SV

BRC-100 is a proposed standard (likely in draft status, based on the GitHub repository context) for a unified, vendor-neutral, unchanging, and open wallet-to-application interface in the Bitcoin SV (BSV) ecosystem. It defines a standardized API for communication between wallets and applications, emphasizing security, scalability, decentralization, and trustlessness. The goal is to enable seamless integration across different wallet vendors and applications, abstracting underlying implementations while supporting comprehensive functionalities like transaction management, identity handling, encryption, and digital signatures.

Here are two simple recipes for making Garlic Spray and Vinegar Spray to deter squirrels and birds in a garden:

1. Garlic Spray Recipe

Garlic has a strong odor that can help repel squirrels, birds, and other pests.

Ingredients:

  • 10-12 cloves of garlic (or 2-3 tablespoons of minced garlic)
  • 1 liter (about 4 cups) of water
  • 1 teaspoon of dish soap (optional, helps the spray stick to plants)
  • A fine-mesh strainer or cheesecloth

To identify spam programmatically across a large dataset of survey responses across surveys, you can take a multi-pronged approach that includes statistical analysis, machine learning, and heuristic-based methods. Here’s a strategy you can implement:

1. Heuristic-Based Rules for Identifying Spam

Start by defining clear rules that could help flag potentially suspicious responses. These rules should be tuned to the nature of your surveys but might include the following:

  • Repeated Entries from the Same IP: Responses coming from the same IP address multiple times in a short period might indicate spam.
  • Unrealistic Completion Times: Responses completed too quickly or too slowly compared to the average time could be flagged. If the time to complete a survey is abnormally fast, it might suggest the respondent didn’t provide genuine answers.
  • Uniform or Repetitive Answers: If responses to multiple questions are identical (e.g., all answers are “1” or "Yes"), it could indicate spam

What are the foundational documents for a city in california?

The foundational documents for a city in California, typically involve a set of core legal and organizational documents that define the governance, responsibilities, and operations of the city. These documents often include:

  • City Charter: Not all cities have a charter, but for those that do, the charter acts as the "Constitution" for the city. It outlines the organizational structure, powers, and functions of the city government. Charters are approved by the voters of a city.
  • Municipal Code: This is a comprehensive collection of the laws and ordinances adopted by the city council. It covers a wide range of regulations, including zoning, public safety, and building codes.
  • General Plan: A long-range planning document that serves as a blueprint for the city's future growth and development. It addresses various elements such as land use, housing, transportation, and environmental quality.
  • Annual Budget: This document details the city's fi
