Linked Data / Semantic Web vs REST

The relation of Linked Data/Semantic Web to REST - ANSWERS:

With all this theory, practical "rest" is "take it easy" JSON over HTTP.

Unfortunately, better solutions don't always win.

It would be much better to have a semantic model for either REST-full

a tiled Windows Phone feel to the interface; Microsoft services like Skype and Outlook; and some solid Nokia services, such as its Here maps and Mix radio. Call it “Windroid.”

... but even as they use an operating system based on the Android Open Source Project, you can’t tap the million-plus apps in Google’s Play store, or get popular Google apps such as Gmail and Chrome. Developers can modify Android apps to run on the devices, and Nokia will offer “hundreds of thousands” of apps in its app store...

REST: REpresentational State Transfer

Fielding Dissertation: CHAPTER 6: Experience and Evaluation:

"The name "Representational State Transfer" is intended to evoke
an image of how a well-designed Web application behaves:
a network of web pages (a virtual state-machine),
where the user progresses through the application by selecting links (state transitions),
resulting in the next page (representing the next state of the application)
being transferred to the user and rendered for their use."

JavaScript Monads

Douglas Crockford: JavaScript the Good Parts  @ pluralsight

DouglasCrockford/monad @ GitHub

a monad is a structure that represents computations defined as sequences of steps.
  • a monad consists of a type constructor M and two operations, bind and return (where return is often also called unit). 
  • The return operation takes a value from a plain type and puts it into a monadic container using the constructor, creating a monadic value. 
  • The bind operation performs the reverse process, extracting the original value from the container and passing it to the associated next function in the pipeline, possibly with additional checks and transformations.
"Identity monad" (wrapper around a value)

    function MONAD() {
        return function unit(value) {
            var monad = Object.create(null);
            monad.bind = function (func) {
                return func(value);
            return monad;
    var identity = MONAD();
    var monad = identity("Hello world.");

result equivalent to: alert("Hello world.");

Because of its functional nature, JavaScript is a good platform for monads.
In fact, many libraries, including pervasive jQuery are extensively using monads.

Extensive usage of JavaScript can't be avoided anymore in web development.
Even on server side node.js sometimes has better efficiency than other languages.

JavaScript has elements of Lisp in disguise...
This is "a revenge of Lisp:" to get powerful effects like Lisp,
JavaScript code becomes as cryptic as Lisp's...

Many JavaScript libraries and frameworks
that could be used without real understanding,
But this may be like an early "singularity".
(i.e. put a dog on a airplane, it will arrive to a destination
without any understanding what happened; no offence to dogs)

'Flow' in game design

Be one with Flappy Bird: The science of 'flow' in game design | Mobile - CNET News"A core reason why recent hits like Flappy Bird and Threes found success -- and are massively addictive -- lies in the way they put us in a unique zen-like state known as flow."

(Flappy Bird game is removed from app store;
there is a similar web based game: Play flappy Doge)

Too bad that this and similar games are perfectly useless, except for "killing time".
But there may be some value in this approach, except for making advertising money.

Conditions for achieving such a state (Flow)
  • There must be a clear and simple task
  • that task must provide instant feedback
  • there must be no distractions that either disrupt your concentration or make you ultra-aware of your own actions; and, key to the act of game playing especially, 
  • it must be a challenge with appropriate balance with regards to your own skill and the task's difficulty.
...creating a near-unequivocal difficulty balance
no matter how good at games you were...

So the task needs to get harder if the user is more skilled,
but not too hard to be not possible to do it.

In fact that would be relatively easy to implement
by adjusting difficulty based on monitoring user's actions.

The same concept could be used for (gamification) in learning / education,
as well as in web sites and other apps.

Flow theory postulates three conditions that have to be met to achieve a flow state:
  • One must be involved in an activity with a clear set of goals and progress. This adds direction and structure to the task.
  • The task at hand must have clear and immediate feedback. This helps the person negotiate any changing demands and allows him or her to adjust his or her performance to maintain the flow state.
  • One must have a good balance between the perceived challenges of the task at hand and his or her own perceived skills. One must have confidence in one's ability to complete the task at hand.
"Challenging assignments that (slightly) stretch one's skills lead to flow"
4.09: Go With The Flow @ Wired
According to Mihaly Csikszentmihalyi, great Web sites are not about navigating content, but staging experience

What do you mean by flow?
Being completely involved in an activity for its own sake. The ego falls away. Time flies. Every action, movement, and thought follows inevitably from the previous one, like playing jazz. Your whole being is involved, and you're using your skills to the utmost...

A Web site that promotes flow is like a gourmet meal. You start off with the appetizers, move on to the salads and entrées, and build toward dessert. 

Unfortunately, most sites are built like a cafeteria. You pick whatever you want. That sounds good at first, but soon it doesn't matter what you choose to do. Everything is bland and the same. 

Web site designers assume that the visitor already knows what to choose. That's not true. People enter Web sites hoping to be led somewhere, hoping for a payoff.

Douglas Crockford claims JavaScript has, "some of the best parts of any programming language ever created." 
He explains why in this course, quizzes you on functional programming and covers the monad in the final lecture of the course."
Unearthing the Excellence in JavaScript

JSLint,The JavaScript Code Quality Tool

He starts with "Programming Style and your brain",
and reference to book "Thinking Fast and Slow"
by Nobel laureate Daniel Kahneman

Optical illusion: squares A and B are exactly same color!

Proof, by Edward H. Adelson @ MIT

Curly Braces, left or right? C, C++, Java, C#: does not matter.
In JavaScript it does!

return // this is a silent error in JavaScript, returns "undefined"
{  // this is due to automatic insertion of semi-column ; feature
   ok: false;

return { // this is OK in JavaScript
   ok: true;

Switch statement: "fall-trough hazard"; always need a "break"
simple solution: don't use the feature that could cause errors.

Example from literature: use or space, comma, dot, uppercase and lowercase is reducing error rate, and increasing read-ability of the text.
The Elements of Style by William Strunk, Jr.
"Programs must communicate clearly to people"

example "rule":
* no space between function name and (
* one space between any other name and (

function () {  ...
}(); // syntax error in JavaScript, can't immediately invoke function

(function () { ...
})(); // this is OK in JavaScript, can immediately invoke function, but looks ugly

(function () { ...
}()); // this also works in JavaScript, but looks better

never rely on semi-column insertion, always put them in place 

with statement ambiguity;
with (o) { foo = koda; }
1. = koda;
2. = o.koda;
3. foo = koda;
4. foo = o.koda;
could be ANY of 4 options, depending on context.
Don't use "with" statement. 

== statement is ambiguous, since it does type conversion first
0 == '' // true
0 == '0'  // true
'' == '0' // false
false == 'false' // false
false == '0' // true
" \t\r\n " == 0 // true
use ===, never == (in listed cases it will all be false)

Don't use \ as last character in line for continuation to next line.
If a space is added after \, this will cause syntax error. 

if (a = b) {...} // this is not good style
a = b; if (a) {...} // this is what happens
if (a === b) {...}  // not this. 

in most languages are "block scope", can be nested
in JavaScript it is "function scope"
Problem is that JavaScript has syntax that is same as in block scope languages.
"var" statement is moved to top of the function in JavaScript
and that can cause errors
function foo() { .... var myVar=0; ...}
function foo() { var myVar=undefined; ... myVar=0; ... }

conclusion: in JavaScript (that is function scope)
declare all variables at start of the function, 
that is where there are declared anyway by compiler!

Also, declare all functions before you call them.

for (var i ... ) { ... }
// variable i is NOT scoped to the loop in JavaScript, it is to function

Global variable are evil in all languages, 
but they are sometimes unavoidable in JavaScript
Advice: write global variables in UPPERCASE

Constructions functions should be named with InitialCaps
and nothing else should be named the same
to avoid confusion with missing "new" statements

var a = b = 0;
var a =0, var b = 0; // it is NOT doing this
b = 0; var a = b; // instead it is initializing global variable b, and local a 

++ was invented to increment pointers; should not be used
use x += 1 instead; x++ is not ++x

if (a) b(); c(); 
if (a) { b(); c(); } // not the same
if (a) { b(); } c(); // this is what happens, obviously 
Advice: always put curly braces in!

"As processes become more agile, coding must be more resilient" 

"Language Sub-setting"
"only a mad man would use all of C++"

"Premature optimization is root of all evil" - Donald Knuth
The function statement is a short-hand for
a var statement with a function value.
function foo() {}
expands to
var foo = function foo() {};
which further expands to
var foo = undefined;
foo = function foo() {};

Closure ("the most important thing"):
var digit_name = (function () {
  var names = ['zero', 'one', 'two', 'three', 'four', 'five', 'six', 'seven', 'eight', 'nine'];
  return function (n) { return names[n]; };
alert(digit_name(3)); // 'three'

returned function has access to names[] even when original function is gone. 

Power Constructors
  1. Make an object: Object literal, new, Object.create, call another power constructor
  2. Define some variables and functions.: These become private members.
  3. Augment the object with privileged methods.
  4. Return the object.
function myPowerConstructor(x) {
  var that = otherMaker(x);
  var secret = f(x);
  that.priv = function () {
    ... secret x that ...
  return that;

On The Road To The Self-Driving Car | On Point with Tom Ashbrook:
"The National Highway Traffic Safety Administration said Monday it will soon require all new cars to talk to one another.  Share location, speed, direction and more, electronically.  Vehicle-to-vehicle – “V2V” – communication.  Right behind that comes the next frontier:  self-driving cars.  First they talk to one another, next they drive themselves.  The auto industry, Google, and the law are all gearing up."

Surprise: ‘Vehicle-to-Vehicle’ Communication Is Already Here | On Point with Tom Ashbrook
"They are literally talking about being able to transit ten pieces of data every second. And it will be everything from your car position, via GPS, to how well you brake, how well you are braking, are you hitting ice, are you turning left are you turning right, are you speeding — all of that information constantly transmitted in a radius of about 300 yards or so, maybe more, and other cars in the vicinity picking up all that information. It all amalgamates in each other’s computers and the cars..."

This information could also be used to adjust traffic lights to improve throughput, for example, and traffic signs including traffic lights could also transmit info to cars, or even mobile phones / devices in the cars.

Why not use existing mobile devices and mobile networks to "enhance driving?" To some extent this is already happening, since traffic information on Google maps is partially based on info from mobile devices...

Energy Trouble Making

The Tense Trail Of The Keystone XL Pipeline | On Point with Tom Ashbrook: "Keystone XL Pipeline from Canada’s Tar Sands country through the heart of America and hear the furious debate over its fate."

Oil sands - Wikipedia, the free encyclopedia

Tony Horwitz's Photos Along The Keystone XL Pipeline

There is "Terraformation" (make something, i.e. Mars, look as Earth)
and there is a "Venusformation" (making Earth hot as Venus :)

Instead of dirty oil pipelines to support "commuting",
people should be making optical lines for "telecommuting",
electrical power lines to transfer clean energy
and fresh water pipelines to provide reliable clean water.

And this is not only in USA, but world-wide.
Invest in clean and smart technologies!

Software Patents

podcast .NET Rocks!:

"Carl and Richard talk to Jonathan Zuck about the state of software patents today. The conversation starts out talking about some of the craziness around software patents - patent trolls, extortion-like letters and the like. Jonathan talks about the changes made by the US to patent law in 2012, and how the biggest challenge today is cleaning up poorly written patents from the DotComBoom era. Also mentioned is a document for application developers created by ACT Online for what to do if you receive a patent demand letter. Check out the links in the show description for the document!"

There are no software patents, only "business process" patents that include software.

New Zealand does not allow software patents anymore.

There is a patents reform coming, and patents are even mentioned in "state of the union" this year.

MEAN Web Dev Stack

Building AngularJS and Node.js Apps with the MEAN Stack - Online Training Course for Developers:
MEAN (Stack) is a boilerplate that provides a nice starting point for MongoDB, Node.js, Express, and AngularJS based applications. It is designed to give you quick and organized way to start developing of MEAN based web apps with useful modules like mongoose and passport pre-bundled and configured. We mainly try to take care of the connection points between existing popular frameworks and solve common integration problems.

common element: JavaScript.
Compared to previous "LAMP", this web stack can work on any OS
But JavaScript may also evolve soon to more "typed" languages, Dart and maybe TypeScript...

Kodak's Patents fire sale for 5% of estimate

The Lowballing of Kodak's Patent Portfolio - IEEE Spectrum:

In January 2012, Kodak filed for Chapter 11 bankruptcy protection
Kodak portfolio of patents experts valued as high as US $4.5 billion.
"Eleven months later, those roughly 1700 patents (together with 655 patent applications) sold for just $94 million—less than the licensing fees Kodak had collected in its worst-ever year in recent history.

What’s more, the company licensed its remaining 20 000 patents to a dozen leading technology companies for only $433 million, severely restricting future earnings from them."

Kodak chart 2
Kodak’s original auction for its 1700 imaging and printing patents attracted over 20 possible bidders. However, the strongest purchasers formed two consortia, led by patent aggregators Intellectual Ventures and RPX. Neither consortium’s bid was high enough to allow Kodak to escape Chapter 11 bankruptcy. Along with three smaller companies, the consortia then merged into a superconsortium whose members dominate the digital world in the 21st century. Its final bid was successful.

Embedded ASP.NET Web Server

For years, embedded web server in Visual Studio was Cassini.
It was also available as open source from Microsoft.
Then it disappeared from web site.

There is also some projects on This may be original (copy)

New Katana/OWIN solution requires re-write of web applications.
It is better for new projects, and is part of "One ASP.NET" (MVC 5)

Proper "binary distribution" solution for hosting existing ASP.NET (WebForms and MVC) from Microsoft is IIS Express.
This requires running .MSI to install the tool, and to host it in a Windows service.

Download Internet Information Services (IIS) 7.5 Express from Official Microsoft Download Center (can run on Windows 2003 R2 and XP)

Download Internet Information Services (IIS) 8.0 Express from Official Microsoft Download Center (supports Windows 8.x)

Why bother when (almost) every Windows 7 and 8.x has IIS as a feature that can be enabled? Because that "enabling" takes 5-10 minutes!
For simple embedded apps that is too much waiting...

Glenn Block on Splunk, Web API book

Herding Code 185: Glenn Block on Splunk:

"Splunk has a product that gathers operational intelligence. It’s got a data analytics platform which understands a lot of log formats. It can handle streaming logs and has a bunch of API’s. It can index in realtime, handles unstructured data, and has some advanced pattern matching features."

The interesting part is that the platform is apparently processing events,
detecting patterns and indexing... and is used by 50% of fortune 500 companies...

Brian Eno, Danny Hillis: The Long Now, now

podcast conversation about 10000 year clock, and many other things
Brian Eno, Danny Hillis: The Long Now, now - The Long Now:

the 10000 years (mechanical) clock has 10 bells,
and can play different permutation for each day of those 10000 years.
10! = 3 628 800
365.25 * 10000 = 3 652 500so it is "almost" every day a new tune...

one of interesting pieces of information, "unsustainable now":
85 richest people own as much as bottom 50% of people. 
(those 85 people) combined owns about 46% of global wealth

ASP.NET += Angular

Yet Another Podcast #119– ASP.NET & Angular | Jesse Liberty:
Apparently Microsoft ASP.NET team is committed to include first class support for AngularJS in Visual Studio and ("One") ASP.NET
By Google or not, that is what developers want.

It will likely be optionally combined with TypeScript also,
and will have "higher-level" design features. Nice.

After jQuery, Bootstrap, and then node.js and even Git,
Microsoft is embracing (and extending :) most popular open source web projects.
Even Hadoop is supported on Azure...

With this, AngularJS may achieve its stated goal to be included in HTML itself.
For last a few months AngularJS class is #1 on Pluralsight.

3D Printing Patents Expiring

Laser Sintering 3D Printing May Now Take Off with a Very Important Patent Expiring Today -

(5 years ago) "If it wasn’t for the expiration of this patent, MakerBot probably wouldn’t be around, and they certainly would not be selling 3D Printers for $1375 (Although the owner of the patent, Stratasys ended up acquiring MakerBot).  Prior to the patents expiration, you would typically find a printer that used this FDM technology to cost in the $25,000 range."
