book: The Internet to the Inner-Net

The Internet to the Inner-Net: Five Ways to Reset Your Connection and Live a Conscious Life: Gopi Kallayil: 9781401944506: Books

"The Internet has become humanity’s invisible central nervous system. It connects us and can sometimes overwhelm us. Yet the most important technology is within us—our brain, body, and consciousness. A fast-paced career in the high-tech industry in combination with a deep yoga and meditation practice has allowed Gopi Kallayil to integrate his inner and outer technologies to a remarkable degree."

Strategies, "rituals of the life" that lead to peak performance:
  1. Focus on the essential
    "things that are more important should not be
    a the mercy of things that are less important"- Goethe
  2. Do one thing at the time
    no "continuous partial attention"
  3. 1 minute of "inner-net" each day 
    "mindfulness", i.e. yoga + meditation, 1 of 1440 minutes in a day
  4. Appointments for mindfulness: one hour out of 168 in each week
    non-negotiable, "anchors" every week, "sharpen the saw"
  5. Friend yourself
    the most important relationship one can ever have is with yourself

Microsoft PowerApps

Microsoft's new service makes app developers out of everyday employees | Network World
"Microsoft just unveiled a new beta service ... allowing anyone to build an app -- no software development experience required. PowerApps combines a cloud application backend with easy-to-use tools that make creating a mobile app a drag-and-drop affair.

PowerApps applications can pull in information from a variety of data sources including Office 365, Dynamics, Google Drive, Workday and other services. Developers can also build connections for PowerApps in their own services if there isn’t a connector already available.

Once the data connection is set up, users can then start building an application interface from one of Microsoft’s pre-built templates, or plug key data into PowerApps and let the service suggest the right designs for their purposes. Those people who have a strong idea for what they want their app to look like can create it from scratch."

"With PowerApps, Microsoft is (competing with) Salesforce and SkyGiraffe"

UrhoSharp: 3D game engine wrapper in C#

Xamarin is all about "wrappers for APIs".
Here is another interesting one, a 3D game engine wrapper in C#

UrhoSharp - Xamarin
"UrhoSharp is a cross-platform high-level 3D and 2D engine that can be used to create animated 3D and 2D scenes for your applications using geometries, materials, lights and cameras."
It is a .NET binding to the Urho3D engine and allows developers to write cross platform code that can target Android, iOS, Windows and Mac with the same codebase and can render to both OpenGL and Direct3D systems.
UrhoSharp is a game engine with a lot of functionality out of the box"

SkiaSharp: Cross-Platform 2D Graphics

Cross-Platform 2D Graphics with SkiaSharp | Xamarin Blog
"SkiaSharp, a cross-platform, high-performance 2D API for .NET developers available across mobile, desktops, and servers.

SkiaSharp provides a powerful C# API for doing 2D graphics powered by Google’s Skia library, the same library that powers Google Chrome, Firefox, and Android’s graphic stacks."
Skia gives us the same graphics output across all platforms, is actively maintained, and offers great features not found elsewhere, like filters and hardware accelerated graphics."

Given that .NET core does not yet have portable graphics library, and that Xamarin is now part of Microsoft, it could very well be that another part of Chrome browsers (besides of V8 JavaScript engine that is part of Node.js used in Visual Studio etc) can become part of Microsoft toolset.
That may in fact be very good solution, like Google's PDFium PDF rendering library is. 
Embrace and collaborate.

There are many more GUI tools portable across platforms, i.e. 
"Qt runs on Android, iOS, Windows Phone, Windows RT, BlackBerry10 and Sailfish"

book: Peak (Science of Expertise)

book 'Peak' by Anders Ericsson, review by Brian Johnson
Anders Ericsson  K. Anders Ericsson - Wikipedia, the free encyclopedia

Peak by Anders Ericsson - YouTube
  • Gift: Adaptibility: everybody has that gift
  • Practice
    • Naive practice
      • keep doing same thing: useless
    • Purposeful practice
      1. Goal
      2. Focus
      3. Feedback
      4. Stretch out of comfort zone, "homeostasis", tendency to seek stability
        then body/brain overcompensates, and that is how you adapt and improve!
    • Deliberate practice
      • usually only in already established fields (chess, music, sports)
        where it is clear what is experts performance and steps how to get there
        (teacher and methodology)
  • Mental representations are changing
    as a result of purposeful/deliberate practice
    Repeating important ideas deepens knowledge/expertise
  • 10000 h rule: is not a rule; number depends on domain;
    the rule is "a lot" of deliberate practice to achieve excellent performance
  • Homo Exercens (= "practicing/improving person"
    vs. Homo Sapiens = "knowing/wise person")
    Humans differentiate from other beings is that we can continuously improve ourselves
The key for getting better and aspiring to be at the "peak performance"
is knowing that you can get better.

"How can you tell when you’re dealing with a genuine expert? 
  •  First, it must lead to performance that is consistently superior to that of the expert’s peers. 
  • Second, real expertise produces concrete results. 
  • Finally, true expertise can be replicated and measured in the lab.

Fragile JavaScript NMP

There is a price for a large number of dependencies of JavaScript modules...

How one developer just broke Node, Babel and thousands of projects in 11 lines of JavaScript • The Register
"Programmers were left staring at broken builds and failed installations on Tuesday after someone toppled the Jenga tower of JavaScript. A couple of hours ago, Azer Koçulu unpublished more than 250 of his modules from NPM, which is a popular package manager used by JavaScript projects to install dependencies. Koçulu yanked his source code because, we're told, one of the modules was called Kik and that apparently attracted the attention of lawyers representing the instant-messaging app of the same name. According to Koçulu, Kik's briefs told him to rename the module, he refused, so the lawyers went to NPM's admins claiming brand infringement. When NPM took Kik away from the developer, he was furious and unpublished all of his NPM-managed modules.

== "Bot Framework": Microsoft AI, ML

Recent "Build 2016" conference introduced new "Bot Framework"
that is suggested to be as important in future as  .NET framework is now.
A bold statement.

Thanks to power of Azure cloud computing resources and improvements in AI and ML,
natural language communication becomes a real possibility,
enabling next generation of voice based interfaces.
So after GUI, Web, Touch here comes a flexible and natural "conversation" computing.
Cortana (Microsoft), Siri (Apple), Google Now, Alexa (Amazon) are examples.
With "Bot Framework" "conversation" can be added to any application.

The same idea was around for a long time with name "Intelligent Agents",
apparently name "Bot" is found to be more market-friendly.
With IoT, Bots, ubiquitous computing is becoming a reality.

Bot Framework
"Build and connect intelligent bots to interact with your users naturally wherever they are, from text/sms to Skype, Slack, Office 365 mail and other popular services."

F# resources; Currying

interesting course: F# Fundamentals | Pluralsight

fsharp-cheatsheet @ GitHub

Home | F# for fun and profit

F# Software Foundation (

Try F#

F# Workshop

F# Programming - Wikibooks, open books for an open world

F# language has an interesting feature called currying. 
Curry is a spice from India region, as well as a tree whose leaves a used a spice.

Curry - Wikipedia, the free encyclopedia Curry tree - Wikipedia, the free encyclopedia
  Curry Trees.jpg
"Red roast duck curry (hot and spicy) from Thailand"

Curry leaves are in a sequence, one by one, same as F# function arguments.
But that is not a reason why the currying feature is named...

Currying | F# for fun and profit
"Breaking multi-parameter functions into smaller one-parameter functions

...if a mathematical function can only have one parameter, then how is it possible that an F# function can have more than one? The answer is quite simple: a function with multiple parameters is rewritten as a series of new functions, each with only one parameter. And this is done automatically by the compiler for you. It is called "currying", after Haskell Curry, a mathematician who was an important influence on the development of functional programming."

To see how this works in practice, let’s use a very basic example that prints two numbers:
//normal version
let printTwoParameters x y = 
   printfn "x=%i y=%i" x y
Internally, the compiler rewrites it as something more like:
//explicitly curried version
let printTwoParameters x  =    // only one parameter!
   let subFunction y = 
      printfn "x=%i y=%i" x y  // new function with one param
   subFunction                 // return the subfunction

// example: function: distance (x, y) { return Math.Abs(x - y); }
let distance x y = x - y |> abs
// val distance : x:int -> y:int => int
distance 5 2
is equivalent to:
(distance 5) 2
let distance5 = distance 5 // a new function with one argument
// val distance5 : (int -> int)
distance5 2
// val it : int = 3

Functions as First-Class Values (F#)

Prefix vs Infix Functions:
(+) 1 3
is equivalent to: 
1 + 3 

// function that adds 1 to its argument:
let add1 = (+) 1
// val add1 : (int -> int)

Infix functions can help make expressions more readable, i.e.:
1 + 2 + 3
// is same as
(1 + 2) + 3
// is same as
((+) ((+) 1 2) 3)
// "associative" if order of applying arguments does not change result
(1 + 2) + 3 == 1 + (2 + 3)
// "non-associative"
(36 / 6) / 2 != 36 / (6 / 2)
// same example in Lisp / Clojure
// (+ (+ 1 2) 3)

// infix function must use symbols; distance function equivalent:
let (|><|) x y = x - y |> abs
// usage:
5 |><| 2
// val it : int = 3

5 |><| 2 |><| 10
// val it : int 7

Lambda Expressions (anonymous functions):
(fun x -> x * x)
usage as a function argument to another function; lambda is symbol -> (fun x -> x * x) [1;2;3]
// distance function
(fun x y -> x - y |> abs) 5 3

let rec length = function // no-name argument is immediately passed to matching
    | [] -> 0 // if argument is an empty list
    | x::xs -> 1 + length xs // else x: head of list; xs: tail of list

let rec factorial n =
    if n < 2 then 1
    n * factorial (n - 1)

Pipe Operators:
sin 2.
is equivalent to:
2. |> sin
"pipe" operators simplify "chaining" functions  
2. |> sin |> ((*) 3)  // == sin(2) * 3
pipe operator can be in both direction, this is same as above
sin <| 2. 

pipe operator can be combined:
min 12 7
is equivalent to:
12 |> min <| 7
is equivalent to (multiple arguments, double pipe operator):
(12,7) ||> min 

Function composition:
let minus1 x = x - 1
let times2 x = x * 2
is equivalent to:
let minus1 = (+) -1  // !! not the same as (-) 1
let times2 = (*) 2

times2 (minus1 9)
is equivalent to:
(times2 << minus1) 9
is equivalent to:
times2 << minus1 <| 9
is equivalent to:
let minus1times2 = times2 << minus1
minus1times2 9
is equivalent to:
let minus1times2 = minus1 >> times2 
minus1times2 9
