Some info about Rust

RUST came out from Firefox to solve problem related to: performance and security.

Why Rust is "faster" compared to C++, C or other compiled language?

• Similar to these languages
• Strong Type System
• Rust compiler uses LLVM suite: Rust compiles to LLVM bytecode and then to assembly language
• You can write less code compared to other programming language

Notes from Purple Cow

Purple Cow: Transform Your Business by Being Remarkable

• create remarkable products that people seek out.
• no one is going to eagerly adapt to your product.
• ideas that spread are more likely to succeed than those that don't.
• services that are worth talking about get talked about.
• it is useless to advertise to anyone (except interested sneezers with influence).
• is not marketing done to a product. The marketing is the product, and vice versa.

Takeaways from TDD and Software Design

video

• TDD by its own CANNOT leads to good design, obviously
• TDD as a mechanism to help us to learn more about good design
• Software is "Soft" just because it can be changed, it is not meant to be settled in the stone
• Test-first programming can help the team to reduce defects but it will not lead to good design

Internet Scale Services Checklist

A checklist for designing and developing internet scale services, inspired by James Hamilton's 2007 paper "On Desgining and Deploying Internet-Scale Services."

• http://mvdirona.com/jrh/talksandpapers/jamesrh_lisa.pdf

Basic tenets

• Does the design expect failures to happen regularly and handle them gracefully?
• Have we kept things as simple as possible?
