bigthink: "Flipped Office"

Have We Reached 'Peak Car'? What Driving Might Be Like in 2030 | Think Tank | Big Think:
"Getting every-other Friday off (the 5/4 schedule) became standard by 2015, establishing the 3-day weekend every other week as the norm. By 2020, this was every weekend, as people moved to a 9 hour day, 4 days per week at the office, and the other 4 hours were “at home” work – checking email on the long weekend, erasing once strict separation of home and work. By 2025 taking every-other Monday off (the 4/3 schedule) was established in most large employers. Today we are seeing half-days on Wednesdays for many office workers, with only Tuesdays, Wednesday, and Thursdays as interactive collaboration days. The “flipped” office, where people were expected to do “work” at home on their own computers, and only show up for meetings is now standard."

wired: Supersized Turkey Dinner

Give Thanks? Science Supersized Your Turkey Dinner - Wired Science:
"Your corn is sweeter, your potatoes are starchier and your turkey is much, much bigger than the foods that sat on your grandparents’ Thanksgiving dinner table.

Most everything on your plate has undergone tremendous genetic change under the intense selective pressures of industrial farming. Pilgrims and American Indians ate foods called corn and turkey, but the actual organisms they consumed didn’t look or taste much at all like our modern variants do."



“Americans (today) eat a pound of sugar every two-and-a-half days. The average amount of sugar consumed by an Englishman in the 1700s was about a pound a year,”


The result: super-sized healthcare.gov web site...
Isn't web and software development also becoming too big and too much dependent of "sugar"?
What are in essence simple requirements are bloated by various libraries and tools (think SharePoint :)

.net 4.5: Thread.Sleep vs Task.Delay

Blocking is "out", "Async" is "in" with .NET 4.5
and and PCL (Portable Class Library)

c# - Thread.Sleep replacement in .NET for Windows Store - Stack Overflow
Windows Store apps embrace asynchrony - and an "asynchronous pause" is provided by Task.Delay. So within an asynchronous method, you'd write:
await Task.Delay(TimeSpan.FromSeconds(30));
... or whatever delay you want. The asynchronous method will continue 30 seconds later, but the thread will not be blocked, just as for all await expressions.
Behind the simplified syntax is a timer, so there is some overhead.
It just from one place (theread/OS) to another (generated code).
Price of progress...

  1. A bias for action, active decision making - 'getting on with it'.
    Facilitate quick decision making & problem solving
    tends to avoid bureaucratic control
  2. Close to the customer -
    learning from the people served by the business.
  3. Autonomy and entrepreneurship -
    fostering innovation and nurturing 'champions'.
  4. Productivity through people-
    treating rank and file employees as a source of quality.
  5. Hands-on, value-driven - management philosophy that guides everyday practice - management showing its commitment.
  6. Stick to the knitting -
    stay with the business that you know.
  7. Simple form, lean staff -
    some of the best companies have minimal HQ staff.
  8. Simultaneous loose-tight properties -
    autonomy in shop-floor activities plus centralized values."

Billion-Dollar Software Companies

The Next 50 Ideas for Billion-Dollar Software Companies | LinkedIn

Since Netscape's public offering in 1995, more than 6,500 pure Internet companies have raised venture capital. But only 18 are worth more than $1 billion. Thirty years after the software revolution started, only 12 of the Fortune 500 are pure software companies.



As Netscape founder Marc Andreesen observed in his 2011 essay, "Why Software Is Eating the World," software is probably the most powerful lever for change the world has ever seen.

real world is in some cases becoming more virtual. But what's more important now is that the virtual world is becoming real




a conclusion: to make software (virtual) a big (and important) business, merge it with real (physical) business.
There are many real-world problems that can significantly benefit from software.

SQL Makes a Comeback through NewSQL: @ InfoQ

"After losing ground to NoSQL – initially perceived as “No more SQL”, and later as “Not only SQL”, the old SQL knows a comeback these days. One of the advertised solutions has been sharding, but for some this is not enough. 

New ways have to be found, some of them combining the two technologies, SQL and NoSQL, others by improving the performance and scalability capabilities of relational stores, all of these being known as NewSQL. 

Google, one of the first supporters of NoSQL, built F1, a distributed relational database combining the high availability and scalability of BigTable with the “consistency and usability” of SQL. 

Google describes F1 in the whitepaper F1: A Distributed SQL Database That Scales (PDF) as:… a fault-tolerant globally-distributed OLTP and OLAP database built at Google as the new storage system for Google's AdWords system. It was designed to replace a sharded MySQL implementation that was not able to meet our growing scalability and reliability requirements."

"Amazon.com started off delivering books through the mail. But its visionary founder, Jeff Bezos, wasn’t content with being a bookseller. He wanted Amazon to become the everything store—a store that offered limitless selection and seductive convenience at disruptively low prices. To do so, he developed a corporate culture of relentless ambition that transformed retail in the same way Henry Ford revolutionized manufacturing."

F# vs. Scala


The F# Software Foundation   vs.  The Scala Programming Language

An Unbiased Comparison of F# and Scala - Tim Kellogg
"Scala is a more approachable language than F# but F# has a stronger sense of type safety. F# also has a much stronger type inference system, which leads to less type annotations. Regardless, I think Scala will recieve a much broader uptake given that it has a much more familiar syntax to C/C++/Java/C# developers. On some level, I like to think of Scala as being more of “a better C#” than “like F#”. Each will have it’s uses, but I think Scala will go far because of that."

TechNeilogy: F# vs. Scala, My Take at Year Two:
"the choice of F# vs. Scala is probably determined by a single external factor: whether one is targeting the .NET ecosystem or the Java ecosystem. So the real-world debate is less likely to be F# vs. Scala than it is to be F# vs. C# or Scala vs. Java. "


Microsoft was supporting port of Scala to CLR/.NET,
but since release of F# that is not active anymore.
Scala on Microsoft .NET | The Scala Programming Language

F# is distributed with Visual Studio, and is also open source,
so it may already have more users than Scala, despite unusual F# syntax.

Scala: "Working Hard to Keep It Simple"

A quick introduction to Scala programming language by its creator

O'Reilly OSCON Java 2011: Martin Odersky, "Working Hard to Keep It Simple" - YouTube:



Concurrency vs Parallelism - What is the difference? - Stack Overflow

Concurrency is when two tasks can start, run, and complete in overlapping time periods. It doesn't necessarily mean they'll ever both be running at the same instant. Eg. multitasking on a single-core machine.

Parallelism
 is when tasks literally run at the same time, eg. on a multicore processor.
  • Parallelism: A condition that arises when at least two threads are executing simultaneously.
  • Concurrency: A condition that exists when at least two threads are making progress. A more generalized form of parallelism that can include time-slicing as a form of virtual parallelism.

"Joda Time is the industry standard date and time handling library for Java.
Noda Time is an idiomatic port to the .NET platform."


Scala School by Twitter

Scala School: @ GigHub
"Scala school started as a series of lectures at Twitter to prepare experienced engineers to be productive Scala programmers. Scala is a relatively new language, but draws on many familiar concepts. Thus, these lectures assumed the audience knew the concepts and showed how to use them in Scala. We found this an effective way of getting new engineers up to speed quickly. This is the written material that accompanied those lectures. "

Cars that runs on natural gas

How to Switch America's Cars From Gasoline to Natural Gas - WSJ.com
Not only is natural gas a lot cheaper than oil right now, but its emissions are much cleaner than gasoline or diesel
GM unveils Impala that runs on natural gas, gasoline


2015 Chevrolet CNG-Capable, Bi-Fuel Impala ... full-size sedan can run on both cleaner-burning, mostly domestically produced compressed natural gas (CNG) or gasoline.
A separate CNG fuel tank, mounted in the trunk, enables the driver to switch between fuels at the push of a button. CNG is less costly and significantly reduces carbon dioxide emissions.

...Only Honda has a natural-gas powered car on sale nationwide, a Civic.


2012 Honda Civic Natural Gas Overview - Official Site

Vehicles | Natural Gas-Powered Vehicles | NGVs 
Public transportation across the country has been using CNG for decades. Currently, about 12-15% of public transit buses in the U.S. run on natural gas (either CNG or LNG –liquefied natural gas).


Agile "pigs & chickens"

Tech writers should be pigs, not chickens - SD Times: Software Development News:

"In any agile project, there are pigs and chickens. These terms describe the level of involvement that any particular person has within a team.
Pigs are those project members who are fully committed to the project and are accountable for its outcome. Anyone else is a chicken.
Chickens might consult with the team, help remove blockers, or track the progress of the project.


These terms come from a story: Pig and Chicken. Pig and Chicken are walking along, and Chicken says, “Hey, we should open a restaurant together!”
Pig thinks for a minute and asks, “What would we call it?”
Chicken says, “I’ve got the perfect name! We’ll call it ‘Ham ‘n Eggs!’ ”
Pig replies, “No thanks. I’d be committed, but you’d only be involved.”

C# Singleton Pattern by Jon Skeet

C# in Depth: Implementing the Singleton Pattern

Thread safety without locks

public sealed class Singleton {
    private static readonly Singleton instance = new Singleton();
    // Explicit static constructor to tell C# compiler           
    // not to mark type as beforefieldinit
    static Singleton() { }
    private Singleton() { }
    public static Singleton Instance { get { return instance; } }
}

Fully lazy instantiation:
public sealed class Singleton {
    private Singleton() { }
    public static Singleton Instance { get { return Nested.instance; } }
    private class Nested  {
        // Explicit static constructor to tell C# compiler
        // not to mark type as beforefieldinit
        static Nested() { }
        internal static readonly Singleton instance = new Singleton();
    }
}

Git: Source Code Graph

Jim Webber declared, in his excellent Neo4j presentation @ InfoQ
A Little Graph Theory for the Busy Developer
that most of data could be represented as a graph.

For example, Git distributed source control system is using graph model,
instead of typical "linear".

Quick introduction to git internals for people who are not scared by words like Directed Acyclic Graph.
Git for Computer Scientists


Git is now in even in TFS and Visual Studio, so almost all of source code is a
Giant Global Graph ... Could be searched by Google's Knowledge Graph,
and even by Facebook's Social Graph Search :)





Android's "Photo Sphere"

This is one year old "news", where Android 4.2 included "Sphere" photo capture tool, along with standard Photo, Video and Panoramic.
But there is still no obvious way how to view such images outside of phone.
Google+ apparently has a tool for that.

Hands-on with Android 4.2's Photo Sphere: Connect:
"The easiest way to view your Photo Spheres on a computer is to upload them to your Google+ account. Click here and here to see our two samples from above on Google+.
