AI: $100 million Amazon's "Alexa Fund"

The Alexa Fund
"The Alexa Fund provides up to $100 million in venture capital funding to fuel voice technology innovation. We believe experiences designed around the human voice will fundamentally improve the way people use technology. Since introducing Alexa-enabled devices like the Amazon Echo, we’ve heard from developers, device-makers, and companies of all sizes that want to innovate with voice. Whether that’s creating new Alexa capabilities with the Alexa Skills Kit (ASK), building devices that use Alexa for new and novel voice experiences using the Alexa Voice Service (AVS), inventing core voice-enabling technology, or developing a product or service that can expand the boundaries of voice technology..."

Starbucks's Virtual Assistant


Starbucks unveils a virtual assistant that takes your order via messaging or voice | TechCrunch
"Starbucks is embracing the trend towards voice-based computing with the launch of a new feature in its mobile app called My Starbucks barista, which allows customers to order and pay for their food and drinks just by speaking. This includes being able to modify their drink order, as if they were speaking with a barista in real life. Additionally, the company is launching a skill for the Amazon Alexa platform, which lets customers re-order their favorite items by speaking to their Echo speaker or other Alexa-powered device."

ideas: a new SMART acronym

Podcast: Take Control of the New Year with Michael Hyatt - Evernote Blog

"Specific, Measurable, Actionable, Risky—this is a key idea here—and then finally Time-keyed.

Risky. Most people set their goals too low. Sometimes people translate the R into Realistic. Actually, that’s the worst thing you could possibly do if you want to follow through on a goal. All the research shows this. If you want to follow through on a goal, it needs to be harder, not easier. A goal that’s easy won’t command your attention. You need for it to be in your discomfort zone.

there are three zones: 
  • "comfort zone: Nothing hard about it. It’s forgettable.
    You don’t need a goal that’s in the comfort zone
  • discomfort zone: is when you begin to feel a little bit of fear, a little bit of uncertainty, a little bit of doubt. Those negative emotions are actually positive indicators that you’re on the right path, that this is something where you’re going to get a breakthrough result. Something where you’re going to experience something extraordinary.
  • delusional zone. This is where you set the goals so high that there’s no way that you could possibly accomplish it, or no way that you could accomplish it without sacrificing all the other areas of your life."
"Failure’s kind of overrated. One of the best ways to make progress is to fail and to fail fast."

Software-Defined Networking (SDN)

Cloud computing is based and accelerated on SDNs...

Enabling the Digital Revolution: SDN and Beyond @ MIT TR
"...data centers are undergoing a once-in-a-generation architectural shift, from hardware- to software-centric models. Just as virtual machines supplanted physical servers as the fundamental element of modern server applications, software-defined networking (SDN) is now emerging as a more flexible, manageable way to organize a data center’s network needs."

"Software-defined networking (SDN) is an approach to computer networking that allows network administrators to programmatically initialize, control, change, and manage network behavior dynamically via open interfaces [1] and abstraction of lower-level functionality. SDN is meant to address the fact that the static architecture of traditional networks doesn't support the dynamic, scalable computing and storage needs of more modern computing environments such as data centers. This is done by decoupling or disassociating the system that makes decisions about where traffic is sent (the control plane) from the underlying systems that forward traffic to the selected destination (the data plane)."

aPaaS vs PasS

4 letter acronyms are not enough anymore, now we need 5 letters... "aPaaS" The idea of RAD (Rapid Application Development) is almost as old as software development... what is different this time?

Application Platform as a Service - aPaaS | WaveMaker
"...services that primarily offer application development and deployment are referred to as application Platform as a Service or aPaaS while PaaS refers to entire spectrum of middleware as a service offerings..."

Market Guide for Application Platforms @ Gartner
"Commercial Java Platform, Enterprise Edition (Java EE) platforms' revenue declined in 2015, indicating a clear shift in the application platform market. 
Application platform as a service (aPaaS) revenue is currently less than half of application platform software revenue, but aPaaS is growing at an annual rate of 18.5%, and aPaaS sales will supersede platform software sales by 2023."

SalesForce is more than 50% of SaaS market now, and Microsoft is growing quickly Office 365. They both support "Apps" and marketplaces / stores for those apps.

Kubernetes: Update on Kubernetes for Windows Server Containers

Kubernetes 1.5 comes to Windows Server 2016 | InfoWorld

Kubernetes Now Leads on LinkedIn and Other Awesome Stats (Infographic) - Apprenda

SIG-Windows presents Windows Server Containers with Kubernetes, running on Microsoft Azure - YouTube
"Microsoft, in collaboration with Docker, is introducing a new feature called Windows Server Containers with Windows Server 2016, which enables Docker containers to run on Windows.

The Kubernetes SIG-Windows team, led by Apprenda, has enhanced Kubernetes to support Windows Server Containers (and Windows Server 2016 as the operating system of choice for the windows-based kubelet)."

"Kubernetes (commonly referred to as "k8s") is an open source container cluster manager originally designed by Google and donated to the Cloud Native Computing Foundation. It aims to provide a "platform for automating deployment, scaling, and operations of application containers across clusters of hosts".[3] It usually works with the Docker container tool and coordinates between a wide cluster of hosts running Docker."

Kubernetes: Borg: The Predecessor to Kubernetes
All of Google services run only on containers, never on VMs.
The management evolved from "Borg" to now "Kubernetes".

SDN is missing on Windows, so no complete parity with Linux for now.

Cloud, Mobile: CPU vs SoC, FPGA, TPU, GPU...

Cloud and mobile are introducing significant changes in types of processors used.
Engineering optimization is not limited to ever higher number of transistors in chips resulting in Moore's law of doubling every 18-24 months. Alternative architectures are also used now.
This is a significant opportunity for businesses to leverage.
It is also a classic "numbers game", where huge sales are driving specialized optimization.

"Field Programmable Gate Array, or FPGA. In contrast to a purpose-built chip which is designed with a single function in mind and then hard-wired to implement it, an FPGA is more flexible. It can be programmed in the field, after it has been plugged in to a socket on a PC board."

"Tensor Processing Unit (TPU), a custom ASIC we built specifically for machine learning — and tailored for TensorFlow. We’ve been running TPUs inside our data centers for more than a year, and have found them to deliver an order of magnitude better-optimized performance per watt for machine learning. This is roughly equivalent to fast-forwarding technology about seven years into the future (three generations of Moore’s Law)."

How the SoC is Displacing the CPU – Medium
"This shift from mostly performance-centric chips to mostly power-constrained chips and the focus on lowering cost and increasing system-level integration has disrupted the traditional semiconductor landscape within just a decade and continues to reshape the industry today."

"Mobile SoCs are now very competitive to standalone CPUs. They offer matched/better compute performance, matched/better graphics within a lower power envelope and a 10X lower price-point. In addition, a single chip SoC solution is far better suited to a mobile formfactor than a multi-chip CPU solution (Source: Intel/Chipworks)"

IBM Quantum Computer is running on extremely cold environment, very near absolute 0 K and it has total of (only) 5 Qubits accessible via cloud, used mostly for scientific research. 
Quantum physics is well established science (while complex and mind-bending) but technology is using it for computing is still in early stages. "Cloud" is a very useful for providing access to such complex tools. Google also has a quantum computer for its internal usage. 

"Whereas common digital computing requires that the data be encoded into binary digits (bits), each of which is always in one of two definite states (0 or 1), quantum computation is analog and uses quantum bits, which can be in an infinite number of superpositions of states.

== Progressive Web Apps (PWA) ==

podcast interview
Making a Web App Progressive with Christian Heilmann @ .NET Rocks! vNext
"... how PWAs really are progressive - you can add bits of these new capabilities to your existing web sites and see some benefit. It starts with the manifest that helps create an icon on a desktop or smartphone to get access to the website, so your user doesn't have to type the URL anymore. And it goes from there, adding offline capabilities, notifications and more. Different browsers are in different states of implementation with PWAs, but the movement is clear, doing more with web apps"

Progressive Web Apps  @ Google

"Progressive Web Apps are user experiences that have the reach of the web, and are:
  • Reliable - Load instantly and never show the downasaur, even in uncertain network conditions.
  • Fast - Respond quickly to user interactions with silky smooth animations and no janky scrolling.
  • Engaging - Feel like a natural app on the device, with an immersive user experience."

"When launched from the user’s home screen, service workers enable a Progressive Web App to load instantly, regardless of the network state.

A service worker is like a client-side proxy, written in JavaScript and puts you in control of the cache and how to respond to resource requests. By pre-caching key resources you can eliminate the dependence on the network, ensuring an instant and reliable experience for your users."

"Progressive Web Apps are installable and live on the users home screen, without the need for an app store. They offer an immersive full screen experience with help from a web app manifest file and can even re-engage users with web push notifications.

The Web App Manifest allows you to control how your app appears and how it's launched. You can specify icons for the home screen and splash screen which is shown while the app is loading. Which page is loaded when the app is launched, screen orientation, even whether to show the browser chrome or not"
