0 · About the User and Your Role

The person you are assisting is User.
Assume User is an experienced senior backend/database engineer, familiar with mainstream languages and their ecosystems such as Rust, Go, and Python.
User values "Slow is Fast", focusing on: reasoning quality, abstraction and architecture, long-term maintainability, rather than short-term speed.
Your core objectives:
- As a strong reasoning, strong planning coding assistant, provide high-quality solutions and implementations in as few interactions as possible;
- Prioritize getting it right the first time, avoiding superficial answers and unnecessary clarifications.

Summary of book "Clean Architecture" by Robert C. Martin

Uncle Bob, the well known author of Clean Code, is coming back to us with a new book called Clean Architecture which wants to take a larger view on how to create software.

Even if Clean Code is one of the major book around OOP and code design (mainly by presenting the SOLID principles), I was not totally impressed by the book.

Clean Architecture leaves me with the same feeling, even if it's pushing the development world to do better, has some good stories and present robust principles to build software.

The book is build around 34 chapters organised in chapters.

Howto Install clamav on OSX with brew

Note: on legacy intel system the path may be /usr/local/etc/clamav instead of /opt/homebrew/etc/clamav/

$ brew install clamav
$ cd /opt/homebrew/etc/clamav/
$ cp freshclam.conf.sample freshclam.conf

Code is clean if it can be understood easily – by everyone on the team. Clean code can be read and enhanced by a developer other than its original author. With understandability comes readability, changeability, extensibility and maintainability.

General rules

Follow standard conventions.
Keep it simple stupid. Simpler is always better. Reduce complexity as much as possible.
Boy scout rule. Leave the campground cleaner than you found it.
Always find root cause. Always look for the root cause of a problem.

Using MobX with decorators in React Native

The following instructions should work with React Native v0.32:

Install mobx libraries.

npm install mobx --save
npm install mobx-react --save

	$ git remote rm origin
	$ git remote add origin [email protected]:aplikacjainfo/proj1.git
	$ git config master.remote origin
	$ git config master.merge refs/heads/master

	- Open Automator
	- File -> New -> Service
	- Change "Service Receives" to "files or folders" in "Finder"
	- Add a "Run Shell Script" action
	- Change "Pass input" to "as arguments"
	- Paste the following in the shell script box: open -n -b "com.microsoft.VSCode" --args "$*"
	- Save it as something like "Open in Visual Studio Code"

	#!/bin/bash

	SWAPFILE=/var/swapfile
	SWAP_MEGABYTES=2048

	if [ -f $SWAPFILE ]; then
	echo "Swapfile $SWAPFILE found, assuming already setup"
	exit;
	fi

	container_commands:
	01setup_swap:
	command: "bash .ebextensions/setup_swap.sh"

	# Changed to use content-type flag instead of header: -H 'Content-Type: application/json'
	siege -c50 -t60S --content-type "application/json" 'http://domain.com/path/to/json.php POST {"ids": ["1","2","3"]}'
