"React": JavaScript UI library (from Facebook)

Introducing "Virtual (HTML) DOM" to simplify handling events on web page.
This is different from typical data binding in MVC/MVVM frameworks like Angular.

React | A JavaScript library for building user interfaces: @ GitHub

React uses a virtual DOM diff implementation for ultra-high performance. It can also render on the server using Node.js — no heavy browser DOM required.

React implements one-way reactive data flow which reduces boilerplate and is easier to reason about than traditional data binding.

It is also introducing ".jsx", extension of JavaScript to reduce typing (and is pre-compiled to .js)

Windows 7 Support Ends January 2015, 8.1 August 2014

Microsoft Windows 7 Mainstream Support to End Starting January 2015:

"Microsoft is set to pull the plug on mainstream support for Windows 7, the operating system that continues to run on more than 50% of the world's computers.

Windows 7 users across the globe will be pointed towards Microsoft's extended-support scheme from January 2015, where security fixes will be provided free of cost by the company, but hotfix updates will need to be paid for."

Microsoft Focussing Intensively on Windows 9: Announces 'Business' 'End of Support' for Windows 8.1

According to a ZDNet report, business users will need to switch from using Windows 8.1 OS, to using Windows 8.1 update 1, by 12 August 2014.

So, to get "updates", you must first get "update 1." :) Brilliant marketing...  

Windows updates are becoming a real challenge even for regular users, not to mention admins. 
Is it time for Chrome-like auto updates, that are small and fast?

IoT, ideas: noFree Parking

Freakonomics » Parking Is Hell: A New Freakonomics Radio Podcast
"Everybody likes free parking, including me, probably you. But just because the driver doesn’t pay for it doesn’t mean that the cost goes away. If you don’t pay for parking your car, somebody else has to pay for it. And that somebody is everybody. We pay for free parking in the prices of the goods we buy at places where the parking is free. And we pay for parking as residents when we get free parking with our housing. We pay for it as taxpayers. Increasingly, I think we’re paying for it in terms of the environmental harm that it causes."

The Urban Village:

"Human interaction networks can be inferred from billions of anonymized mobile phone records. This study, focusing on Portugal and the UK, reveals a fundamental pattern: our social connections scale with city size.

The scaling of this relation is 'superlinear,’ meaning that on average, if the size of a town doubles, the sum of phone contacts in the city will more than double – in a mathematically predictable way."

These include pitfalls to avoid, important issues to focus on, and answers to common questions. My fave: First-timers are often surprised by how little time in a ma- chine learning project is spent actually doing machine learn- ing. But it makes sense if you consider how time-consuming it is to gather data, integrate it, clean it and pre-process it, and how much trial and error can go into feature design.

ideas: Making Better Decisions

A 4-Step Process for Making Better Decisions:
Decisive by Chip Heath and Dan Heath

Problem: “four villains”... making decisions:
  • We have too narrow of focus. We are guilty of “spotlight thinking.” We focus on the obvious and visible. We miss important facts outside our immediate view.
  • We fall into confirmation bias. We develop a quick belief about something and then seek out information that confirms that belief.
  • We get caught in short-term emotion. We are too emotionally connected to the decision and struggle with being appropriately detached.
  • We are guilty of overconfidence. We assume that we know more than we actually do know and jump to conclusions, thinking we can accurately predict the future.
Solution: decision-making "WRAP" process:
  • Widen your options.
  • Reality-test your assumptions.
  • Attain distance before deciding.
  • Prepare to be wrong.

Mobile Web vs. "Native" Apps

The broken Promise of the Mobile Web - Rick Strahl's Web Log:

"Apps currently rule the roost when it comes to mobile devices and the applications that run on them. If there’s something that you need on your mobile device your first step usually is to look for an app, not use your browser. But native app development remains a pain in the butt, with the requirement to have to support 2 or 3 completely separate platforms.


But, it doesn’t have to be this way"

IoT: Robustness principle?

Robustness principle - Wikipedia, the free encyclopedia:
"Be conservative in what you send, be liberal in what you accept"

The principle is also known as Postel's law, after Internet pioneer Jon Postel, who wrote in an early specification of the Transmission Control Protocol that:[1]

'TCP implementations should follow a general principle of robustness: be conservative in what you do, be liberal in what you accept from others.'

In other words, code that sends commands or data to other machines (or to other programs on the same machine) should conform completely to the specifications, but code that receives input should accept non-conformant input as long as the meaning is clear.

Now that the Internet is expanding to "Things", it is important that new protocols, APIs and tools keep the system robust, simple and expandable...

For many cases, in particular of mobile (thing) devices, it is more effective to have a thing/device behind an messaging gateway on internet than directly connected. A "thing" and gateway could use private, optimized protocols, and doing "translation" as needed.

In fact this may be preferred method for most of non-server devices and apps, and is different from most of popular internet protocols. Technically, this is "distributed messaging" and in most popular messaging protocols gateways / brokers are not distributed. But email is! Could enhanced email protocols be useful for IoT?

ScratchJr: App vs. Web

It would be better, and more effective, if the tool was HTML5 based, I think.

IoT: protocol "Thread" by Nest and others

Nest Nurtures New IoT Protocol | EE Times:
"Even before its $3.2 billion acquisition by Google, Nest Labs was quietly building into all its products a low-power mesh networking protocol. Now it hopes to make it an industry standard, called Thread, for home automation devices. 

 A handful of chip and system makers, including ARM, Freescale, Silicon Labs, and Samsung, have joined the ad hoc Thread Group led by Nest. It aims to release the royalty-free protocol this year to anyone who joins the group."

Json.NET 6.0, JSON Merge, JSONPath

Json.NET Updates: Merge, Dependency Injection, F# and JSONPath Support: @ InfoQ
"several new features have been added, including several F# specific features, support for JSONPath querying, ability to integrate with Dependency Injection frameworks, ability to Merge JSON objects and more."

James Newton-King - Json.NET 6.0 Release 4 - JSON Merge, Dependency Injection

JSONPath - XPath for JSON
The following XPath expression
would look like[0].title

JSONPath expressions can use the dot–notation
or the bracket–notation

Expressions of the underlying scripting language (<expr>) can be used as an alternative to explicit names or indices as in
using the symbol '@' for the current object. Filter expressions are supported via the syntax ?(<boolean expr>) as in
$[?(@.price < 10)].title

/$the root object/element
.@the current object/element
/. or []child operator
..n/aparent operator
//..recursive descent. JSONPath borrows this syntax from E4X.
**wildcard. All objects/elements regardless their names.
@n/aattribute access. JSON structures don't have attributes.
[][]subscript operator. XPath uses it to iterate over element collections and for predicates. In Javascript and JSON it is the native array operator.
|[,]Union operator in XPath results in a combination of node sets. JSONPath allows alternate names or array indices as a set.
n/a[start:end:step]array slice operator borrowed from ES4.
[]?()applies a filter (script) expression.
n/a()script expression, using the underlying script engine.
()n/agrouping in Xpath
