Amazon Auto ?

Jeff Bezos to employees: 'very excited' about auto industry

"At an all-hands staff meeting in March, Amazon CEO Jeff Bezos told employees that he’s fascinated by the recent developments in the auto industry, adding that it was one of the main reasons why Amazon led a $700 million investment in electric vehicle start-up Rivian in February.

“If you think about the auto industry right now, there’s so many things going on with Uber-ization, electrification, the connected car — so it’s a fascinating industry,” Bezos said according to a recording of the meeting CNBC has heard. “It’s going to be something very interesting to watch and participate in, and I’m very excited about that whole industry.

Bezos’ comments give a rare glimpse into his interest in the auto industry, which Amazon entered in February through its investments in Rivian and another self-driving tech start-up, Aurora. Investing in autonomous technology could eventually help Amazon offer faster and cheaper delivery, as well as automation in other areas, like its cashier-free grocery stores.”

AutoML: Azure, GCP

Introduction to Automated Machine Learning (AutoML) - Software Engineering Daily

"Automated machine learning, or AutoML, is an umbrella term for a particular approach to machine learning that aims to automate any part of the process of building a machine learning model from raw data.

AutoML caught the spotlight after Google announced its AutoML suite, Google Cloud AutoML, and Microsoft announced AutoML in Azure Machine Learning."

.NET Core 3 += gRPC / ProtoBuf

Next version of .NET includes support for (Google's standard) gRPC data protocol with efficient ProtoBuf serialization.

After "tech trend waves" of XML/SOAP and current JSON/REST, ProtoBuf/gRPC (or similar binary serialization) may become more broadly used since it is supported by tools for most of popular client and server platforms.

An Early Look at gRPC and ASP.NET Core 3.0 - Steve Gordon

"gRPC is a schema-first framework initially created by Google. It supports service to service communication over HTTP/2 connections. It uses the Protobuf wire transfer serialisation for lightweight, fast messaging between the services."

"Protocol Buffers (PB) is the "language of data" at Google. Put simply, Protocol Buffers are used for serialization, RPC, and about everything in between."

AI/ML: “As We May Program” by Peter Norvig

A great presentation by Peter Norvig, lead of Google AI research, Stanford and Udacity professor.
A possible future of programming as combination of Voice UI and ML for continuous improvements based on feedback, difference of expected and achieved results. Very interesting.
He concludes with concept of "marketplace for what we need and want.

The Tragedy of the Commons: How Elinor Ostrom Solved One of Life's Greatest Dilemmas - Evonomics

"...avoiding the "tragedy of the commons" without requiring top-down regulation, at least if certain conditions are met (Ostrom 1990, 2010). She summarized the conditions in the form of eight core design principles: 1) Clearly defined boundaries; 2) Proportional equivalence between benefits and costs; 3) Collective choice arrangements; 4) Monitoring; 5) Graduated sanctions; 6) Fast and fair conflict resolution; 7) Local autonomy; 8) Appropriate relations with other tiers of rule-making authority (polycentric governance). This work was so groundbreaking that Ostrom was awarded the Nobel Prize in economics in 2009."

Android: Kotlin first

Kotlin is now Google’s preferred language for Android app development | TechCrunch

"Google today announced that the Kotlin programming language is now its preferred language for Android app developers.

“Android development will become increasingly Kotlin-first,” Google writes in today’s announcement. “Many new Jetpack APIs and features will be offered first in Kotlin. If you’re starting a new project, you should write it in Kotlin; code written in Kotlin often mean much less code for you–less code to type, test, and maintain.”

data: UBER vs JSON => MessagePack

Putting the Squeeze on Trip Data

pareto frontParetoFront
Key conclusions:
  • Simply compressing JSON with zlib would yield a reasonable tradeoff in size and speed. The result would be just a little bigger, but execution was much faster than using BZ2 on JSON.
  • Going with IDL-based protocols, Thrift and Protocol Buffers compressed with zlib or Snappy would give us the best gain in size and/or speed.

...settled on MessagePack with zlib (instead of plain JSON)

A 1 TB disk will now last almost a year (347 days),
compared to a month (30 days) without compression

MessagePack: It's like JSON. but fast and small.

"MessagePack is an efficient binary serialization format.
It lets you exchange data among multiple languages like JSON.
But it's faster and smaller.
Small integers are encoded into a single byte,
and typical short strings require only one extra byte in addition to the strings themselves."

  7. Effective Decisions
How to be effective: THE EFFECTIVE EXECUTIVE by Peter Drucker | Core Message - YouTube
1 page PDF summary @Lozeron Academy

  • To be effective is to be selective with your time. 
  • Ask yourself: What contribution can I make? ->
    "To focus on contribution is to focus on effectiveness." 
  • Know Thy Strengths:
    Maximizing your strengths maximizes your contribution. 
  • Don't know your strengths?
    Volunteer for new roles and get feedback on your performance. 
  • Know Thy Time:
    Maximizing your time maximizes your contribution. 
  • Don't know your time? Keep a time log
    and after a month review your time statement to determine 
    • what you need to stop doing and 
    • what you need offload. 
  • Ultimate Goal:
    Do what you do best, and stop doing or give away the rest.

by Peter F. Drucker 

"What made (an executive) effective is that they followed the same eight practices:
  • They asked, “What needs to be done?”
  • They asked, “What is right for the enterprise?”
  • They developed action plans.
  • They took responsibility for decisions.
  • They took responsibility for communicating.
  • They were focused on opportunities rather than problems.
  • They ran productive meetings.
  • They thought and said “we” rather than “I.”

Steps to effectiveness:
  1. Recording where the time goes
  2. Focus your vision on contribution
  3. Make your strengths productive and focus on using them
  4. Prioritize the most important things first, not necessarily the most urgent
  5. Take rational action
