“Why Learning to Code is So Damn Hard”

Click through for the full post at Viking Code School – as they say, the early part can be easy, then things get tougher, followed by a challenging learning period – until confidence and skills flourish.

What every beginner absolutely needs to know about the journey ahead

Source: Why Learning to Code is So Damn Hard

MIT App Inventor makes many things easier – but eventually one must learn to think like a software developer and become familiar with concepts like data structures, algorithms, design patterns, and software engineering design and project management.

“Siri” for Android, written in App Inventor

Eric Payne has created an Apple Siri – like interface in App Inventor.

You can download his App Inventor source code here from Google Drive. Note that Google Drive displays the content of the .aia file (it is just a .zip file). Click on the “download arrow” icon at top center to download the .aia file to your computer, and then import the .aia file into your App Inventor account.

Google expected to introduce new Java compiler

The upcoming Jack & Jill compilers in Android | Saikoa.

Most Android apps are written in the Java programming language. Google’s Android software development system converts “source code” (a text file) written in Java, into the code that runs on the Android device.

In many programming language systems, source code is converted into the “machine instructions” of the processor. The processor does not speak “Java” but speaks its own language. A program called a “compiler” converts the original program source code into the “machine language” of the processor.

Many programs for Windows, for example, have been converted into the individual instructions that are processed by an Intel or AMD processor. The “compiler” converts the program source code into a .exe file that contains the machine language instructions of the Intel and AMD processor.

But what if you wanted your program to run on a hardware device that has a Qualcomm or ARM processor?

What are the hot programming languages for today

Here is an easy to read report on which programming languages are now “hot” in the market for software developers: Don’t Rely On Salary Data To Pick A Programming Language To Learn – ReadWrite.

The pace of change in software development is rapid – popular languages today may already be fading.  Pay scales for some niche languages are very high (such as Ruby)- but the market opportunity might not be large or lengthy.

Web applications and mobile applications are the “hot” categories. Within those categories, there are a variety of currently popular software development tools:

MIT App Inventor Source Code

This is for advanced software developers only: MIT App Inventor Sources. That’s the actual source code that makes App Inventor work behind the scenes – from the browser based editor to the server side support to the AI Companion. It’s all there.

MIT has made the source code for App Inventor publicly available. At a minimum, you need to be proficient in Java, Javascript, and have familiarity with various web techniques, such as JSON. Exploring this source code is not for the neophyte.

With access to the source code it is possible to host App Inventor on your own server and it is possible to develop your own App Inventor components (this also requires making a custom version of AI Companion).

Again, this is for advanced software developers.
