Amazon EC2 - Provides virtual servers - Supports multiple OS - Resources optimized for different workloads: memory/CPU intensive, storage, etc

Test doubles lingo - "Fake" implementation of real services (eg: in-memory db) - "Stubs" return certain values when invoked - "Mocks" keep track of interactions (eg: number of invocations) - "Spies" verify interactions with and/or mock some parts of a dependency

If you want to confuse your enemies, give them the source code. If you want to really confuse them, give them the documentation.

Have pride in solving problems Not in writing code

Decipher the classic Java public static void main(String args[]) - public: anyone can call this method - static: function belongs to class, not to a particular instance - void: return type - main: function name - String: argument type - args[]: array of strings

Scripts (like tests) are part of your system. You need to version-controll, maintain, test, and refactor them. They will make you go fast in the mid/long term.

Explicit is better than implicit - The Zen of Python

A delayed write goes to disk after spending some time in a buffer: to improve efficiency, instead of sending every write operation directly to disk, data is put into a buffer and queued for writing to disk later. System calls like fsync are used to write directly to disk.

I'm planning to have a Q&A call when there are 100 people in this channel (only 50 more people).

Help me by sharing this channel with friends and people who are interested in programming. The sooner we reach 100, the sooner we'll start having calls.

Also, leave a reply to this message with questions and topics you'd like to discuss during the call

Basics of most programming languages * Variables * Data types * Conditionals (if - else) * Loops (for - while) * Functions * Arrays * Dictionaries * Classes and objects That's enough to build many interesting applications

Basic regex matches: - ^ -> beginning of string - $ -> end of string - \d -> digit - \D -> non-digit - x? -> optional - x* -> x any number of times - x+ -> x 1 or more times - x{n,m} -> x from n to m times - (a|b|c) -> either a, b or c

Does your definition of done include writing automated tests, at different levels, for both technical and non-technical requirements?

Python tip: Instead of -> if not a is b: Prefer -> if a is not b: Easier to read and understand.

JavaScript was developed by Brendan Eich in 1995 Javascript is often just-in-time compiled and is considered a core technology along HTML and CSS for web development. Javascript can be used both for front and backend development console.log("Hello World");

If there's a QA team in your company, set yourself the goal that they will not find any issues in your code.
