C11 / C++11
A good brief summary of changes in C and C++ languages, in their latest versions: 11
C11/C++11: Building blocks for the future - SD Times: Software Development News:
With Visual Studio 2012 (codename VS11), most of latest C++11 is also available
to developers on Microsoft platform. This may in particular be useful for Windows 8
"Modern" / Store applications development, where C++ is one of 3 "equals" for apps development.
This is important, since for mobile devices (phones, tablets), battery efficiency and performance
are important, if nothing else to be competitive with iPhone/iPad.

Canvas Drawing @ Khan Academy
Khan Academy is now teaching web programming with interactive web drawing tools...
They are not the only one with interactive canvas tool.
w3schools.com also has similar, but much less "fun" tool:
Computer Science | Khan Academy
Here is the program, a snippet of JavaScript for drawing on canvas
// Winston's handsome features don't need outlines
noStroke();
// face
fill(255, 255, 0);
ellipse(202, 208, 300, 300);
// eyes
fill(46, 46, 41);
ellipse(157, 151, 40, 40);
ellipse(304, 142, 40, 40);
// mouth
fill(252, 65, 65);
ellipse(257, 240, 120, 136);
They are not the only one with interactive canvas tool.

7 Google Maps API Alternatives
The top seven alternatives to the Google Maps API | Feature | .net magazine
"Google's Map API is one of the most popular JavaScript libraries on the web, used by more than 350,000 websites. And with good reason – it's powerful and for six years was absolutely free.
...
in October 2011 when its announced it would start charging the heaviest users of Google Maps
Google's price was quite high – $4 per thousand map views
...
By June, Google realised it had priced its maps too high and was in danger of losing most of its potential paying customers, so it dropped the price by 88% to 50 cents per thousand views. But the damage had been done. Other vendors and open-source solutions had already attracted attention as reasonable alternatives."

Windows 8: Designing UX for apps
UX = User eXperience (it used to be UniX :)
Microsoft is very serious about "re-imagining" Windows. The Windows 8 ("Metro", "Modern", "Store") apps have strict guidelines how they should look and behave. Current design is result of long and deliberate process... possibly even some inspiration...
Anyway, when apps are submitted to Windows Store they are evaluated to make sure the intent of Windows designers is preserved. The "Wild West" attitude that was a hallmark of Windows for long time is left to Android to struggle or prosper with...
Designing Windows 8, or how to redesign a religion
Developer downloads for programming Windows Store apps
- Have a Vision: The most important part of designing a Windows Store app is
determining what the app will be great at. - Design guidance for Windows Store apps
Windows 8 Product Guide for Developers
Microsoft design principles:
The Microsoft design style puts content before chrome and helps you build attractive, easy-to-use apps that will delight your customers with their intuitive and common interaction model. Some principles common to great Windows Store apps include:
Some more marketing speak...
Embracing these principles makes your app more usable, increases its visual appeal, and helps you deliver an experience that’s consistent and familiar to your users.
Windows 8 represents the single biggest platform opportunity available, and business terms of the Windows Store represent a developer-first point of view. The registration fee for individuals is $49 USD, with a $99 USD fee for companies. The revenue share is 70%, but when an app achieves $25,000 USD in revenue—aggregated across all sales in every market—that changes to 80% revenue share for the rest of the lifetime of the app.

Its handset profits, fueled by the introduction of its high-end Galaxy S III model in May, leapt 75 percent over the previous year. Samsung’s stock has gained over 65 percent in the last year
Samsung had 24.1 percent of the global handset market compared with Apple’s 6.4 percent at the end of the last quarter. Samsung also had a commanding lead in the lucrative smartphone market: 32.6 percent compared with Apple’s 16.9 percent, although the gap is likely to narrow because of the iPhone 5’s introduction.

Erlang, pros and cons
Erlang programming language was controversial since it was created in Ericsson,
as super-reliable platform for telephone exchange devices.
With syntax of Prolog, and unique semantics similar to Lisp,
it was a puzzle for everybody. Yet, it has proven to be so reliable,
that they could not even measure downtime. No downtime for years.
There is another side-effect of Erlang's simple functional design: it is very optimal
for parallel processing. So, the language is recently re-discovered, and used in some
prominent projects, including CouchDB.
For example, a "process" in Erlang takes about KB of memory,
and a "thread" in .NET takes about MB of memory. And Erlang process provides insulation of data,
and .NET (or Java) thread does not. Huge difference.
After initial success, the other side of Erlang become evident: it is not very efficient
for common tasks such as processing text. For document-oriented database that could be a problem.
In particular when competition tools, usually written in C/C++ are more efficient.
So, CouchDB creator is on his new quest, to port portions of the system to C/C++,
and keep Erlang for what is it good for.
This presentation provides nice overview of pluses and minuses of Erlang.
The conclusion is that "strange syntax" is main reason for relatively small adoption,
and consequently lack of investment (and results) in performance optimization.
Erlang, the Language from the Future?
Presented by Damien Katz on Aug 28, 2012
Damien Katz Abandons Apache CouchDB, Continues with Couchbase Server
What Sucks About Erlang by DAMIEN KATZ
On the other side, some people try to take "right tool for the job", and are attempting to use
Erlang for coordination and monitoring other tools.
podcast: Alex Robson about polyglot programming @ .NET rocks
In Erlang, "failure" is "normal" and planned for. Each process is designed to detect and handle
failure of monitored processes, and "tree" of processes is self-healing, where failed processes are detected and replaced automatically. Since there is no shared state, only messaging, it is not hard to scale system, and make it reliable...

Open/closed principle
“software entities … should be open for extension, but closed for modification”.
L LSP
Liskov substitution principle
“objects in a program should be replaceable with instances of their subtypes without altering the correctness of that program”. See also design by contract.
I ISP
Interface segregation principle
“many client specific interfaces are better than one general purpose interface.”[5]
D DIP
Dependency inversion principle
one should “Depend upon Abstractions. Do not depend upon concretions.”[5]
Dependency injection is one method of following this principle.

Genetic Legacy of Genghis Khan
Genghis Khan, the fearsome Mongolian warrior of the 13th century, may have done more than rule the largest empire in the world; according to a recently published genetic study, he may have helped populate it too.
An international group of geneticists studying Y-chromosome data have found that nearly 8 percent of the men living in the region of the former Mongol empire carry y-chromosomes that are nearly identical. That translates to 0.5 percent of the male population in the world, or roughly 16 million descendants living today.

Apple: more Profits, less R&D
Will Apple's Focus on Profits Let Its Rivals Jump Ahead? - Technology Review:
"Apple spends far less than its rivals on research and development? Despite all its bluster about "innovation," Apple devotes a paltry 2 percent of revenue to R&D, versus 14 percent at Google and Microsoft and 6 percent at Samsung. In terms of absolute dollars, Google spends twice as much as Apple on R&D, though it has one-third the revenues. Microsoft spends three times as much as Apple, but has half as much revenues. Samsung's revenues are about the same as Apple, but the Korean company spends 3.5 times as much on R&D.
No wonder Apple makes such an amazing profit. The overall net margin may be 28 percent, but on phones, Apple makes 38 to 42 percent,"

Single Page Applications @ Wikipedia
In an SPA, either all necessary code – HTML, JavaScript, and CSS – is retrieved with a single page load,[1] or partial changes are performed loading new code on demand from the web server, usually driven by user actions. The page does not automatically reload during user interaction with the application, nor does control transfer to another page. Updates to the displayed page may or may not involve interaction with a server.

Rich Hickey (Clojure) Datomic: Database as a Value
Rich Hickey - The Database as a Value | Channel 9
Rich Hickey is the creator of the Clojure programming language.
Recently, he also created a new type of database, Datomic.
Datomic is a database of flexible, time-based facts, supporting queries and joins, with elastic scalability, and ACID transactions. It is implemented in Clojure.
This talk happened at GOTO Chicago Functional Programming Night, sponsored by Dave Thomas.
Rich and Erik Meijer discussing Clojure and Datomic.
Read the "Out of the tar pit" paper Rich mentions at the beginning of the talk.
Rich Hickey - The Database as a Value
Abstract:
Proponents of functional programming tout its many benefits, most of which are available only within a particular process, or afforded by a particular programming language feature. Anything outside of that is considered I/O, dangerous and difficult to reason about. But real systems almost always cross process and language boundaries, and most require, crucially, a very gnarly bit of shared state - a database. In this talk we will examine how Datomic renders the database into that most prized and easy-to-reason-about construct, a value, and makes it available to multiple processes in multiple languages, functional and not.
Along the way, we'll discuss the importance of immutability and time in representing information, the reification of process, and the mechanisms of durable persistent data structures. No knowledge of functional programming is required.
