ASP.NET Core Applications with IIS


Publishing and Running ASP.NET Core Applications with IIS - Rick Strahl's Web Log

"When you build ASP.NET Core applications and plan on running them on IIS, you'll find that .NET Core applications in IIS work radically different than previous versions of ASP.NET....

The most important thing to understand about hosting ASP.NET Core (both based on .NET Core and .NET 4.x) is that it runs as a standalone, out of process Console application. It's not hosted inside of IIS and it doesn't need IIS to run. ASP.NET Core applications have their own self-hosted Web server and process requests internally using this self-hosted server instance."


"Install the .NET Core Windows Server Hosting bundle on the hosting system. The bundle installs the .NET Core Runtime, .NET Core Library, and the ASP.NET Core Module. The module creates the reverse proxy between IIS and the Kestrel server."

"HTTP.sys server (formerly called WebListener) won't work in a reverse proxy configuration with IIS. Use the Kestrel server."

AI is new Electricity, Data is new Oil

Finally a simple solution for sustainable business model with "big data" and "AI"
It takes a great knowledge to explain things in a simple way.
AI expert Andrew Ng of Stanford/Google/Baidu/Coursera did just that in the video below.

Data =>  great AI powered products => more Users => more Data ...

Many inventions at the turn of 20th century completely changed the world.
Before crude and refined oil, industry was powered by coal and horses.
Before electricity generation and transmission, candles illuminated at night.
In only two decades, there ware automobiles and airplanes, electric light and appliances.

At the turn of 21st century, the industry was powered by Excel data and Email "intelligence".
With exponential improvements in computing and connectivity, big data and cloud, DL/AI
we are already in the next phase of great changes and opportunities.

AI vs electricity: The AI startup playbook – Towards Data Science
"market defend-able strategy" as described by Andrew Ng in the video below

  • "AI needs data to work,
    .
  • AI enabled product like a personal assistant will get better with more data.
    .
  • Great products get more users
    and hence more data, further reinforcing this positive feedback loop."

Who should get credit for the quote 'data is the new oil'? - Quora

"Clive Humby, UK Mathemetician and architect of Tesco’s Clubcard, 2006 (widely credited as the first to coin the phrase): “Data is the new oil. It’s valuable, but if unrefined it cannot really be used. It has to be changed into gas, plastic, chemicals, etc to create a valuable entity that drives profitable activity; so must data be broken down, analyzed for it to have value.”

Upspin: global namespace for files

Rob Pike, co-creator of UTF-8 and GoLang, presents "global namespace for files" Upspin

Gopherfest 2017: Upspin (Rob Pike) - YouTube

Upspin architecture · Upspin

Upspin Overview · Upspin

"Upspin provides a global name space to name all your files. Given an Upspin name, a file can be shared securely, copied efficiently without “download” and “upload”, and accessed from anywhere that has a network connection.
Its target audience is personal users, families or groups of friends. Although it might have application in corporate environments, that is not its motivation.
Upspin provides a uniform naming mechanism for all data, along with easy-to-understand and easy-to-use secure sharing, as well as end-to-end encryption that guarantees privacy."

Every Upspin file name has the same basic structure. It begins with the user’s name—an email address—followed by a slash-separated Unix-like path name.
For example,

ann@example.com/dir/file

Dogecoin vs. US banks


Dogecoin Logo.png

Such Cryptocurrency. So Amaze. : Planet Money : NPR

Dogecoin was created for learning about crypto-currency, and giving money to charity.
It is now worth $1.4 B. And as other blockchain system, it enables almost instant and fee transfer of money.

On the other side, US banks are still using ancient system from 1970's, written in COBOL and running on mainframe computers, that takes up to 5 days to transfer money, and the service is expensive for users. But it is very profitable for the banks, so it stays that way, for now at least, until some "Amazon of banking" takes off. 

It is not technical reasons that hold back, in UK similar money transfers take seconds!

DeepMind’s AI became a superhuman chess player in a few hours - The Verge


Chess AI: "Machine Learning" vs "Expert Systems"

"In the paper, DeepMind describes how a descendant of the AI program that first conquered the board game Go has taught itself to play a number of other games at a superhuman level. After eight hours of self-play, the program bested the AI that first beat the human world Go champion; and after four hours of training, it beat the current world champion chess-playing program, Stockfish. 
...
the new AI program, named AlphaZero, wasn’t specifically designed to play any of these games. ... it was given some basic rules ... with no other strategies or tactics. It simply got better by playing itself over and over again at an accelerated pace — a method of training AI known as “reinforcement learning.”

Azure CDN Dynamic Site Acceleration

Azure CDN: Dynamic Site Acceleration | Azure Friday | Channel 9



Tim Ferro » Azure Architect Notes: Azure CDN Dynamic Site Acceleration

“Standard CDN capability includes the ability to cache files closer to end users to speed up delivery of static files. However, with dynamic web applications, caching that content in edge locations isn’t possible because the server generates the content in response to user behavior. Speeding up the delivery of such content is more complex than traditional edge caching and requires an end-to-end solution that finely tunes each element along the entire data path from inception to delivery. With Azure CDN Dynamic Site Acceleration (DSA), the performance of web pages with dynamic content is measurably improved.”

Raspberry Pi not vulnerable to Spectre, Meltdown: well explained

Why Raspberry Pi isn't vulnerable to Spectre or Meltdown - Raspberry Pi

"... Spectre and Meltdown... affect all modern Intel processors, and (in the case of Spectre) many AMD processors and ARM cores. Spectre allows an attacker to bypass software checks to read data from arbitrary locations in the current address space; Meltdown allows an attacker to read data from arbitrary locations in the operating system kernel’s address space (which should normally be inaccessible to user programs).

Both vulnerabilities exploit performance features (caching and speculative execution) common to many modern processors to leak data via a so-called side-channel attack. Happily, the Raspberry Pi isn’t susceptible to these vulnerabilities, because of the particular ARM cores that it uses."
link from: Programming Newsletter - O'Reilly Media

(Raspberry Pi Founder ) "Eben Upton provides an excellent primer on some concepts in modern processor design to help folks better understand how so-called side-channel attacks get some modern processors to leak data."

(in)security: CPU vulnerabilities: Meltdown, Spectre

From being a main concern to overcome when considering "move to cloud"
security is now becoming a prominent reason to do such move.

While there will always be computer security issues
cloud service providers are in the best position to respond quickly,
and handle such serious situations before such issues become a big problem.
Recently discovered CPU security issues are an excellent example.

Having learned details how CPUs work and are designed,
as well as OS, virtualization etc, I could appreciate complexity of this.

These vulnerabilities affect many CPUs, including those from AMD, ARM, and Intel, as well as the devices and operating systems running on them."

Project Zero: Reading privileged memory with a side-channel

"CPU data cache timing can be abused to efficiently leak information out of mis-speculated execution, leading to (at worst) arbitrary virtual memory read vulnerabilities across local security boundaries in various contexts."
