Neo4j graph database appears to have a good business momentum,

with recently released version 2.0

On the other side, with ever improving computing hardware, in particular large memory and SSDs, make even "classic" SQL databases run faster when data are in-memory... (Oracle 12, SQL Server 2014)

With all those good efforts, there are not standardized "service interfaces"
for distributed data, that would preserve semantics and enable flexibility.

Leadership Tips From Ford CEO Alan Mulally

6 Leadership Tips From Ford CEO Alan Mulally - Yahoo Finance:

• Have a Vision
• Don't Just Have a Vision: Have a Plan to Implement It
• When Problems Arise, Disclose Them
• Involve People
• Succession Plan
• Sense of History

Can Alan Mulally save Ford? - May. 11, 2009 @ Fortune magazine

"I arrive here, and the first day I say, 'Let's go look at the product lineup.' 

And they lay it out, and I said, 'Where's the Taurus?' 

They said, 'Well, we killed it.' I said, 'What do you mean, you killed it?'
'Well, we made a couple that looked like a football. They didn't sell very well, so we stopped it.'
'You stopped the Taurus?' I said.
'How many billions of dollars does it cost to build brand loyalty around a name?'
'Well, we thought it was so damaged that we named it the Five Hundred.'
I said, 'Well, you've got until tomorrow to find a vehicle to put the Taurus name on because that's why I'm here. Then you have two years to make the coolest vehicle that you can possibly make.'

Compare Durandal to Angular, Not Knockout to Angular | John Papa


Since Durandal is based on MVVM pattern (instead of MVC used by Angular)
it could be a better match for Microsoft platform (WPF is based on MVVM).
It is also using KnockoutJS created by Steve Sanderson from ASP.NET team.

Microsoft could "adopt" Durandal (and maybe hire its developer),
and create a reasonable alternative to Angular.
Based on recent actions, it is more likely that it may be adopted and supported
as jQuery is in VisualStudio, and Microsoft may sponsor some of the development...

Creating a popular class for PluralSight could be more profitable than Kickstarter...
Angular classes are currently #1 and #2 on PluralSight, and in used in 4 out of top 10...

Shopping from iOS vs Android

IBM Digital Analytics Benchmark - United States
"(shopping from) iOS was more than five times higher than (from) Android, driving 23 percent vs. 4.6 percent for Android. 
On average, iOS users spent $93.94 per order, nearly twice that of Android users, who spent $48.10 per order.
iOS also led as a component of overall traffic with 32.6 percent vs. 14.8 percent for Android."

Simple bottom line: people show have more money are buying more expensive devices (iOS) and buying more stuff from them...  Same is for apps, iOS users are purchasing apps, Android users not (much)... But most of popular apps are free

HTML: fixed table header with scrollable data (Angular?)

Having fixed / floating header in a table is not easy even in Excel.
It should be, that is an obvious use-case.

After 20+ years, HTML still does not have an universal, easy, declarative or plug-in solution either, to preserve semantics of a data table.
Most "solutions" fix width of columns, reducing flexibility of HTML tables, and require investigations, plugins, testing...
Time to add this to HTML6 or as Angular "directives"?

The Day Google Had to 'Start Over' on Android

The Day Google Had to 'Start Over' on Android - Fred Vogelstein - The Atlantic:

"Andy Rubin (lead of Android) was so astonished by what Jobs was unveiling that, on his way to a meeting, he had his driver pull over so that he could finish watching the webcast.

“Holy crap,” he said to one of his colleagues in the car. “I guess we’re not going to ship that phone.”...

What the Android team had been working on, a phone code-named Sooner, sported software that was arguably more revolu­tionary than what had just been revealed in the iPhone....

However, the Sooner phone was ugly. It looked like a Black-Berry, with a traditional keyboard and a small screen that wasn’t touch-enabled."

"The MQL Read and MQL Write APIs provides access to the Freebase database using the Metaweb query language (MQL)."

Freebase, now owned and used by Google, is essentially realization of limited Semantic Web based on data from available sources, such as Wikipedia / Wikidata.

It is apparently implemented as a graph system (database?)
and it also has own query language MQL, based on JavaScript and returning JSON.

As expected, there is also ontology (vocabulary, taxonomy, metaschema)
used for schema and queries.

The raw data are also available as RDF triples data-dumps.

Freebase data is used for Google search results (Knowledge Graph),
and even Microsoft Bing is using Freebase data from their "snapshots".

Kata (型 or 形 literally: "form")
By practicing in a repetitive manner the learner develops the ability to execute those techniques and movements in a natural, reflex-like manner. Systematic practice does not mean permanently rigid. The goal is to internalize the movements and techniques of a kata so they can be executed and adapted under different circumstances, without thought or hesitation.

F# Functions

Functions (F#) @ MSDN

F# is a hybrid functional language, that supports object-oriented (.NET) and functional concepts. It has very compact syntax.
It is so compact that commas and brackets are not used! It takes some time to get used to...
Here are some C# method declarations:

int add(int x, int y) { return x+y; }
string add(string x, string y) { return x+y; }

Here is equivalent function declaration in F#; F# is strongly typed, and compiler can assign data type of function and arguments based on context! In example below, "add 3 5" will produce value 8 of type int; the next line that is commented out would produce a string; so same declaration can be for int and string, but not at the same time, since compiler decides type based on first occurrence.

let add x y = x + y

printfn "%d" (add 3 5)
// printfn "%s" (add "Hello" "World")

F# functions are just values, and can be assigned and passed around as parameters; For example add'  gets assigned a lambda expression (anonymous function), with same meaning as previous declaration:

let add' = fun x y -> x + y

function can have data types declared:

let add (x: int) (y:int) : int =
    x + y

The compiler can also infer function type of parameter from context;
in example below "checkThis" is function declaration that takes two parameters "item" and "f";
f is recognized to be a function parameter, since in "if" statement it is taking item as argument
When calling "checkThis" , lambda expression is used as a value for "f"

let checkThis item f =
    if f item then
        printfn "HIT"
    else
        printfn "MISS"

checkThis 5 (fun x -> x > 3)
checkThis "hi there" (fun x -> x.Length > 5)

that are very slow compared to in-memory.
Plus there is a price of software for each server...
So what is the biggest "box" that can be built, and a what price?

AngularDart

Dart News & Updates: Angular Announces AngularDart:
"port of Angular to Dart.
AngularDart is heavily inspired by AngularJS and is supercharged for Dart. Core Angular features such as directives, data binding, and dependency injection, are all there, and they've taken advantage of Dart's features like metadata, types, and classes to feel natural for Dart developers. AngularDart is also the first version of Angular to be built on emerging web standards like Shadow DOM."

Dart: Web Languages and VMs: Fast Code is Always in Fashion - Google I/O 2013

Web Languages and VMs: Fast Code is Always in Fashion — Google I/O 2013

PayPal Switches from Java to JavaScript

PayPal Switches from Java to JavaScript:
"Running the test suite on production hardware, they concluded that the Node.js app was performing better than the Java one, serving:Double the requests per second vs. the Java application. This is even more interesting because our initial performance results were using a single core for the node.js application compared to five cores in Java. "

The node.js app was:

• Built almost twice as fast with fewer people
• Written in 33% fewer lines of code
• Constructed with 40% fewer files

Node.js at PayPal | PayPal Engineering Blog

...node.js application had:

• Double the requests per second vs. the Java application. This is even more interesting because our initial performance results were using a single core for the node.js application compared to five cores in Java. We expect to increase this divide further.
• 35% decrease in the average response time for the same page. This resulted in the pages being served 200ms faster— something users will definitely notice.

Survival, "The Netflix way"

How Netflix Architects for Survival: @ InfoQ

The Netflix way:

• Everything is “built for three” (i.e. VMs, data centers, etc.)
• Fully automated build tools to test and make packages
• Fully automated machine image "bakery"
• Fully automated image deployment
• Independent teams responsible for both Dev and Ops
• Redundancy through multi-region deployment

Culture of "Freedom and Responsibility"

Automate all the things!

Shared state should be stored in a shared service

RESTfull services APIs (has its own CDN)

Highly aligned, loosely coupled (SOA)

All systems choices assume some part will fail at some point.

Reliability and $ (balance)

The Monkey Theory

• Simulate things that go wrong (automation, tool "ASGARD")
• Find things that are different

Execution

• Running a new and old version clusters (instead of instances) in parallel, until stable

"Baking VMs" means no configuration at startup time, it is fully ready to run when started. 

book: “The Bully Pulpit: Theodore Roosevelt...

Doris Kearns Goodwin On Teddy Roosevelt and the Progressive Era | On Point with Tom Ashbrook:
"...historian is telling the story of Teddy Roosevelt and the transformation of the Progressive Era."



Bully pulpit - Wikipedia, the free encyclopedia 
A bully pulpit is a position sufficiently conspicuous to provide an opportunity to speak out and be listened to.
This term was coined by President Theodore Roosevelt, who referred to the White House as a "bully pulpit", by which he meant a terrific platform from which to advocate an agenda. 

Roosevelt famously used the word bully as an adjective meaning "superb" or "wonderful", a more common usage in his time than it is today. (Another expression which survives from this era is "bully for you", synonymous with "good for you".)

a bully pulpit - Idioms - by the Free Dictionary, Thesaurus and Encyclopedia.

"an important job or position that someone can use to persuade other people to accept their ideas"

i.e. "The presidency is a wonderful bully pulpit to convince the country of the need for a balanced budget."

Udacity: Data Science & Big Data Track (Free vs. Full)

Udacity Blog: Sebastian Thrun: Launching our Data Science & Big Data Track built with Leading Industry Partners:

• Introduction to Salesforce App Development - Udacity
  
• Introduction to Hadoop and MapReduce - Udacity
  
• Intro to Data Science - Udacity
  
• Data Wrangling with MongoDB - Udacity
  
• Exploratory Data Analysis - Udacity

There is still "Free" and a now there are some "Full" courses.
Price: $150/month per class, to get coaching and other help.

Compared with standard corporate training and colleges / universities
that price seems to be a good deal. But compared with PluralSight,
where there is unlimited access to 1000+ professional quality classes
for $30-50/month, it is not a comparison.

Obviously, for PluralSight person needs to be self-motivated. Similarity is that both Udacity and PluralSight are venture-funded by about $20M+ so far... In a way Coursera is more similar to PluralSight, where one is driven by reputation, and other by money... O'Reilly SafariBooksOnline subscriptions also have videos, besides books.

But all those efforts are completely missing on content-contribution, there are no "Wikipedia-like" training systems (that I am aware of)... StackOverflow has questions and answers, and is a great resource, but not organized for systematic learning, for for ad-hock...

Lazy(T) Class

in .NET 4 and newer:

Lazy(T) Class (System):

// The lazy initializer is created here, not the LargeObject
lazyLargeObject = new Lazy<LargeObject>(() => new LargeObject());
// LargeObject is not created yet here...
LargeObject large = lazyLargeObject.Value;
large.Data // only now LargeObject gets initialized

Lazy Initialization of an object means that its creation is deferred until it is first used.

"Legitimacy of Authority" by Malcolm Gladwell

#45. A Summary of ‘David and Goliath: Underdogs, Misfits, and the Art of Battling Giants’ by Malcolm Gladwell | New Books in Brief:
As Gladwell explains, “when people in authority want the rest of us to behave, it matters—first and foremost—how they behave. This is called the ‘principle of legitimacy,’ and legitimacy is based on three things. 

• First of all, the people who are asked to obey authority have to feel like they have a voice—that if they speak up, they will be heard.
  
  
• Second, the law has to be predictable. There has to be a reasonable expectation that the rules tomorrow are going to be roughly the same as the rules today.
  
  
• And third, the authority has to be fair. It can’t treat one group differently from another”

China's 10-year plan "mono-culture"

Motorola Moto G review: how good can a $179 smartphone be? | The Verge


"Comparing the Moto G against more expensive handsets isn't exactly fair. Anyone upgradingto the Moto G is likely to notice a huge leap in performance. That’s true even for those with flagship phones from 2011, like the Samsung Galaxy S II or iPhone 4S, and the difference between the Moto G and any other sub-$200 handset ever is night and day. In the sub-$200 market, only Windows Phone devices like the Lumia 520 and 620 get close to the kind of experience that Motorola is offering here.

this phone truly redefines what a low-end smartphone can be, and is the best attempt yet to turn “the next billion” into smartphone users"

Null: The Billion Dollar Mistake

Null References: The Billion Dollar Mistake: @ InfoQ
"Tony Hoare introduced Null references in ALGOL W back in 1965 “simply because it was so easy to implement”, says Mr. Hoare. He talks about that decision considering it “my billion-dollar mistake”."

Sir Charles Antony Richard Hoare, commonly known as Tony Hoare, is a British computer scientist, probably best known for the development in 1960, at age 26, of Quicksort.
He currently works in Microsoft.

A solution: Null Object pattern - Wikipedia, the free encyclopedia

In object-oriented computer programming, a Null Object is an object with defined neutral ("null") behavior. The Null Object design pattern describes the uses of such objects and their behavior (or lack thereof).

interface IAnimal {
    void MakeSound();
}

class NullAnimal : IAnimal {
    public void MakeSound() {
        // Purposefully provides no behaviour.
    }
}
...
IAnimal unknown = new NullAnimal(); //instead of: unknown = null;
   unknown.MakeSound(); // outputs nothing, but does not throw a runtime exception

Statue of Responsibility

Statue of Responsibility - Wikipedia, the free encyclopedia:
The Statue of Responsibility is a proposed national monument structure to be built on the West Coast of the United States. The prototype, sculpted by project artist Gary Lee Price, consists of a pair of clasped hands oriented vertically, symbolizing many things but primarily the responsibility that comes with liberty.

The Statue of Responsibility was suggested first by scholar Viktor Frankl in his book Man's Search for Meaning. He recommended "that the Statue of Liberty on the East Coast should be supplemented by a Statue of Responsibility on the West Coast." He wrote: "Freedom, however, is not the last word. Freedom is only part of the story and half of the truth. Freedom is but the negative aspect of the whole phenomenon whose positive aspect is responsibleness. In fact, freedom is in danger of degenerating into mere arbitrariness unless it is lived in terms of responsibleness."
