Big Data in Memory

Storing data in custom binary format can significantly reduce storage and increase performance.
This is in particular visible with managed VM languages, like Java (48 Bytes for string "ABC" !!!)
With availability of large-memory computers, big data could fit in memory of a single machine...

data optimization: Traveling 48 States

one year family trip in RV, while working remotely: MAP
" through all of the lower 48 states in one year's time"
by Jonathan “J.” Tower

The Definitive Road Trip? It's Data-Driven : NPR
"Randy Olson, a Ph.D. candidate at Michigan State University and a self-proclaimed "data tinkerer," believes he's devised a route that could allow a family to hit a landmark in each of the Lower 48 states...Randy Olson's algorithm devised the optimal driving route to 50 tourist spots in the Lower 48 states.

Travelling salesman problem - Wikipedia, the free encyclopedia
"The travelling salesman problem (TSP) asks the following question: Given a list of cities and the distances between each pair of cities, what is the shortest possible route that visits each city exactly once and returns to the origin city? It is an NP-hard problem in combinatorial optimization, important in operations research and theoretical computer science."

visualization: The Age of Homes

Following is an interesting visualization map, but it could be misleading
because of using random color to represent ranges of values...
Big data needs smart visualization techniques... but what is a good way?

The Age of Homes in All 50 States | Zillow Blog
"...single-family houses built from 1900 to 2014 to see which decades are most represented by the current housing stock..."

I.e., what is a good way to color-code ranges of values on a chart or a map?

... mapping scalar values to colors... allows us to view scalar fields by coloring surfaces and volumes. ... rainbow color map... which naively sweeps through the most saturated colors, is well known for its ability to obscure data, introduce artifacts, and confuse users.

 bad vs. good  

Based on this observation, next visual map is still not optimal,
while better than just using random colors as on the first map. 

elections are a typical example of using color-maps. 
In that case two main colors are easy choice, 
but different population density creates another challenge: 
colored surface not proportional to number of values. 


A better way is to utilize "bubble map"
Here is one example from Microsoft "Power Map" reporting tool. 
Better, but still not perfect. 

In all, color map visualization challenge appears to be not solved still. 
If there is a good solution, it is hiding well from Google :)

IoT security: Hacking Amazon's WiFi Button

Amazon's has created a very clever and useful Dash Button gadget for easy re-ordering.
The communication protocol is based on WiFi, and somebody already figured out
how this could be intercepted to reuse the button for other purposes,
by just configuring router differently, and then respond to event locally.

This may be an opportunity for Amazon (or somebody else?)
to sell similar buttons with SDK as a general purpose IoT tool.
There will be many places where this could be very useful.

IoT: node.js with Microsoft Edge Chakra engine

CodeChat 035 - Node Chakra | CodeChat | Channel 9

"...a version of Node.js that works with Chakra - the JavaScript engine that underlies Microsoft Edge.
Why would you do this? Well, because ... Windows 10 is not exactly discriminant about which devices it supports... To really work everywhere there are times when the V8 engine isn't going to work.

They're doing it right too. They're not creating a proprietary branch - a road you can't come back from. The newfound versatility they're putting into Node.js is on its way to being contributed right to the main project. That's why this Node.js thing is so awesome - because such a rich community is contributing to it.

Node.js and io.js are settling their differences, merging back together
Node.js and io.js will officially merge codebases under a new entity: the ‘Node Foundation.’
A number of partners have come onboard to sponsor the new organization and help it stay independent, including Famous, IBM, Intel, Joyent, Microsoft and PayPal.

"The io.js TC has voted to join the upcoming Node Foundation. The project will be named Node.js but it will be based on io.js’ repository."

#topical-references (#BigData)
shortened links (
Account originator (@KirkDBorne)
Message identifier (not shown, but every twitter message has one, typically a GUID: f9732f07-ab02-46d4-b869-215e36576dc5, which I'll shorten to f9732f07)
A time stamp (not shown)
Retweet-reference (not shown, but typically an internal link to a previous tweet).
Additional human text message.

After many years it is clear that good ideas of Semantic Web could not be utilized without platform.
There is no much value for standard without tools that support it, and both standards and tools
need to evolve quickly, as "classic web" did.

Semantic Web related technology is used used by Google and others, but data on the web are still very unstructured and difficult to process. It may be time for "data smart-er web..."

(Isomorphic) Universal JavaScript = react.js + node.js @

Isomorphic JavaScript - The future of web app development

"Isomorphic JavaScript apps are JavaScript applications that can run both client-side and server-side. The backend and frontend share the same code."

Isomorphic JavaScript Adopts Universal JavaScript, Drops Java From Rendering Pipeline
"The team behind has switched from a Java-based HTML renderer to a JavaScript one that they can run on both the server and the client.
To decrease the time users spent waiting, Netflix has removed the Java server-based renderer and reduced the amount of HTML sent down the wire. In a post describing the change, Kristofer Baxter, said that by not rendering pieces of the app that the user will never see (among other changes), they've been able to speed up the time til interaction by 70%.
"Universal JavaScript", Netflix architected their new UI renderer so that they can run it in the browser or in a node.js server.

While Netflix has chosen React.js to provide them with this ability, it isn't the only option.

IoT: Google + Carnegie-Mellon + ...

A Look Inside Google and Carnegie-Mellon's IoT Campus | Fast Company | Business + Innovation
"For the "Internet of Things" to thrive, all it needs is for all devices to get along—which is currently wishful thinking. Last week, however, Google announced a partnership with Carnegie-Mellon University, which is leading a collaboration of faculty from several other academic institutions on a project to jump-start the Internet of Things revolution. Their plan: Build a universal platform that lets any device talk to any other device. And fittingly, that master-key solution will be open source.
The joint project between CMU, Cornell, Stanford, Illinois at Urbana-Champaign, and Google wants to wipe away the private-industry middlemen that keep sensors in separate sandboxes by creating a new, open platform: GIoTTO."

“We funded the Open Web of Things expedition to encourage universities to explore various aspects of system design that could help enable the Internet of Things,” said Maggie Johnson, director of university relations for Google. “From the many excellent proposals received, we’ve chosen Carnegie Mellon to lead because of their vision for a living laboratory, validating system design through daily use. Cornell, Illinois and Stanford were selected to join based on their unique approaches for tackling critical challenges related to privacy & security, systems & protocols and HCI."

""Snap2It" lets users link to a printer or projector simply by taking a smartphone photo of it."
"...To create its living lab, CMU will saturate its campus with sensors and infrastructure, recruit student and other campus members to create and use new IoT apps, and eventually expand efforts to the wider Pittsburgh community..."

IoT: Singapore 2.0: "Smart Nation" bet

Singapore 2.0: Lee Seeks Smart City Revamp as Old Model Ebbs - Bloomberg Business
"For 50 years, Singapore has punched above its weight class, thanks to a run of political stability, long-term planning, transparency and openness to investment. Along the way, the tiny Southeast Asian nation turned from a center of colonial administration and trading into a major container port, an oil-refining hub, an electronics manufacturer, and a banking center.
Singapore’s traditional pillars of growth are cracking. Electronics exports have repeatedly declined in recent years, labor productivity fell for a fourth quarter in the first three months of the year and the economy contracted
administration committed S$16.1 billion (US $11.5) to research and development from 2011 to 2015, a 20 percent increase over the previous period

A glimpse of that vision can be seen in Jurong Lake District, a 360-hectare development area in the island’s west where the government has installed more than 1,000 sensors to monitor and control everything from vehicles to trash cans.

Microservices vs. Code

Microservices: Software that Fits in Your Head @ Info

"Dan North describes a model for thinking about the age of code and argues for replaceability as a first class concern. He also discovers that by optimizing for both replace-ability and consistency one can end up with something that looks a lot like microservices."slides: Microservices: software that fits in your head // Speaker Deck

"What is the goal of software development?

To sustainability minimize lead time to (positive) business impact.

The goal is not to produce software!

Code is not the asset…
- writing code costs 
- waiting for code costs 
- changing code costs 
- understanding code costs
Code is the cost!

Microservices can be a 
Replaceable Component 
- if you choose to optimize for 
replace-ability and consistency 
- smaller is not necessarily better 
- more replaceable is better

Google Alphabet Marketing

The real reason for Google's Alphabet announcement: Branding | VentureBeat | Business | by Ari Applbaum, Venture1st
alphabet blocks

"The 12th rule of marketing outlined by Al Reis and Jack Trout in their classic marketing guide, The 22 Immutable Laws of Marketing, is “The Law of Line Extension.” Reis and Trout advise companies to resist the pressure to extend the equity of their brand. Don’t spread too thin and try to be everything for everyone. This applies to product lines: Extending the product line to unproven areas is dangerous. While most companies believe that a power of a brand will help sell new products, often the new product hurts the old one. And the brand gets tarnished along the way
What is Google’s brand? Google’s mission statement is “to organize the world’s information and make it universally accessible and useful.” And the second rule in the company’s “Ten things we know to be true” (AKA “Ten Things”) is “It’s best to do one thing really, really well.”

Google => "Alphabet" (!)

Official Google Blog: G is for Google

What is Alphabet, Google's new company? - Business Insider

"Google just announced a major overhaul of its corporate structure.

As part of the change, the company that used to be called Google is going to become a new holding company called Alphabet. The URL for the new company is

Shareholders will get one Alphabet share for every Google share they previously owned. The executives in charge of Alphabet will be the same execs in charge of Google today — CEO Larry Page, President Sergey Brin, Executive Chairman Eric Schmidt...

Alphabet includes the following entities:

  • A smaller company called Google, headed by CEO Sundar Pichai, that includes the company's core businesses. Those businesses: "search, ads, maps, apps, YouTube and Android and the related technical infrastructure."
  • Other businesses, "such as Calico, Nest, and Fiber, as well as its investing arms, such as Google Ventures and Google Capital, and incubator projects, such as Google X," which "will be managed separately from the Google business."

Identity Server with ASP.NET

Identity Server and ASP.NET with Dominick Baier on the Hanselminutes Technology Podcast: Fresh Air for Developers
"Scott talks to Dominick Baier about identity on the web and in ASP.NET. Dominick and Brock Allen have a great series of open source products in the form of Identity Manager, Identity Server, and Identity Model. What does auth on today's web look like? How does Open ID Connect and OAuth work and how can you set it up in your websites today?"

"IdentityServer is a .NET/Katana-based framework and hostable component that allows implementing single sign-on and access control for modern web applications and APIs using protocols like OpenID Connect and OAuth2. It supports a wide range of clients like mobile, web, SPAs and desktop applications and is extensible to allow integration in new and existing architectures.

Watch this for the big picture: Introduction to OpenID Connect, OAuth2 and IdentityServer."

IdentityServer3 "The big Picture"
security protocols

"Authentication is needed when an application needs to know about the identity of the current user... The most common authentication protocols are SAML2p, WS-Federation and OpenID Connect
API Access
"Applications have two fundamental ways with which they communicate with APIs – 
  • using the application identity, or 
  • delegating the user’s identity. 
Sometimes both ways need to be combined.
OAuth2 is a protocol that allows applications to request access tokens from a security token service and use them to communicate with APIs...

OpenID Connect and OAuth2 – better together

OpenID Connect and OAuth2 are very similar – in fact OpenID Connect is an extension on top of OAuth2. This means that you can combine the two fundamental security concerns – authentication and API access into a single protocol – and often a single round trip to the security token service."

Securing Azure Virtual Network with Network ACL

Securing your Azure Virtual Network using Network ACLs with Narayan Annamalai | Azure Friday | Channel 9

"A Network Access Control List (ACL) is a security enhancement available for your Azure deployment. An ACL provides the ability to selectively permit or deny traffic for a virtual machine endpoint
How ACLs work?
An ACL is an object that contains a list of rules. When you create an ACL and apply it to a virtual machine endpoint, packet filtering takes place on the host node of your VM. This means the traffic from remote IP addresses is filtered by the host node for matching ACL rules instead of on your VM. This prevents your VM from spending the precious CPU cycles on packet filtering."
