Installing TensorFlow on Windows

TensorFlow is an open-source software library for machine learning across a range of tasks. According to Wikipedia, it is a symbolic math library, and also used as a system for building and training neural networks to detect and decipher patterns and correlations, analogous to human learning and reasoning. TensorFlow was developed by the Google Brain team and  was released under the Apache 2.0 open source license on 9 November 2015

 This guide explains how to install TensorFlow on Windows.

Determine how to install TensorFlow

You must pick the mechanism by which you install TensorFlow. The supported choices are as follows:

• "native" pip
• Anaconda

Native pip installs TensorFlow directly on your system without going through a virtual environment. Since a native pip installation is not walled-off in a separate container, the pip installation might interfere with other Python-based installations on your system. However, if you understand pip and your Python environment, a native pip installation often entails only a single command! Furthermore, if you install with native pip, users can run TensorFlow programs from any directory on the system.

In Anaconda, you may use conda to create a virtual environment. However, within Anaconda, we recommend installing TensorFlow with the pip install command, not with the conda install command.

NOTE: The conda package is community supported, not officially supported. That is, the TensorFlow team neither tests nor maintains this conda package. Use that package at your own risk.

Installing with native pip

If neither of the following versions of Python is installed on your machine, install it now:

• Python 3.6.x 64-bit from python.org

-TensorFlow supports Python 3.5.x and 3.6.x on Windows. Note that Python 3 comes with the pip3 package manager, which is the program you'll use to install TensorFlow.

Installing with Anaconda

The Anaconda installation is community supported, not officially supported.

Take the following steps to install TensorFlow in an Anaconda environment:

1. Follow the instructions on the Anaconda download site to download and install Anaconda.
2. Create a conda environment named tensorflow by invoking the following command:

C:> conda create -n tensorflow python=3.6

 

3. Activate the conda environment by issuing the following command:
4. C:> activate tensorflow

 (tensorflow)C:>  # Your prompt should change

5. Issue the appropriate command to install TensorFlow inside your conda environment. To install the CPU-only version of TensorFlow, enter the following command:

(tensorflow)C:> pip install --ignore-installed --upgrade tensorflow

To install the GPU version of TensorFlow, enter the following command (on a single line):

(tensorflow)C:> pip install --ignore-installed --upgrade tensorflow-gpu

Validate your installation

Start a terminal.

If you installed through Anaconda, activate your Anaconda environment.

Invoke python from your shell as follows:

$ python

Enter the following short program inside the python interactive shell:


>>> import tensorflow as tf
>>> hello = tf.constant('Hello, TensorFlow!')
>>> sess = tf.Session()
>>> print(sess.run(hello))



If the system outputs the following, then you are ready to begin writing TensorFlow programs:

Hello, TensorFlow!

How to install The PHP Framework Laravel 5.5 in 5 simple steps on Xampp in Windows

5 simple steps to install Laravel 5 on Xampp in Windows  

Laravel is currently the most popular php-framework. It is an open-source PHP web framework, created by Taylor Otwell and intended for the development of web applications following the model–view–controller (MVC) architectural pattern.  Other Php-frameworks are Symfony and Zend. Take the following simple steps to install the latest version of Laravel in any version of Windows whether Windows 7, Windows 8 or Windows 10.

Step1: The Laravel framework has a few system requirements. 

Check the following requirement.

• PHP >= 7.0.0
• OpenSSL PHP Extension
• PDO PHP Extension
• Mbstring PHP Extension
• Tokenizer PHP Extension
• XML PHP Extension

  If you have Xampp already installed, then don’t worry because you got them already else Download Xampp 7.1.x and installed 

Step2: Download and install Composer

Composer is a PHP package manager that is integrated with Laravel Framework. In Windows, we can install it easy going to the official page and download the installer.

Composer Download page

After install it, we can open a Windows terminal and write composer for execute the command:

Step 3: Configure Xampp VirtualHost

We will configure a VirtualHost (httpd-vhosts.conf) in Xampp for a Laravel project, and in this example, we want to configure the domain lara for our project.

By default, httpd-vhosts.conf   is located in C:\xampp\apache\conf\extra\httpd-vhosts.conf 

Open it with preferably Notepad++ and add following lines at the end of the file:

# VirtualHost for Lara

<VirtualHost laravel.dev:80>

  DocumentRoot "C:\xampp\htdocs\laravel\public"

  ServerAdmin laravel.dev

  <Directory "C:\xampp\htdocs\laravel">

        Options Indexes FollowSymLinks

        AllowOverride All

        Require all granted

  </Directory>

</VirtualHost>

After this, our apache is listening to lara connections from the localhost. However, we need to configure our hosts file that allows to redirect lara to the localhost that is located. That takes us to the next step.

Step4 Configure the Host file

By default, host is located at  C:\Windows\System32\drivers\etc
Edit hosts file adding our localhost for lara:

# localhost name resolution is handled within DNS itself.

#             127.0.0.1       localhost

#             ::1             localhost

127.0.0.1              lara

Save the file and we are ready to install lara.

 

Step5: Install Laravel Framework

We are prepared to install and configure a Laravel Framework. First of all, we have to navigate to htdocs folder to install it and run this following command:

composer create-project laravel/laravel laravel "5.5.*"

Will start the installation of the Framework:

 Just be patient. No news is good news...

 How long it takes will depend on your network. Mine took about 30 minutes.

 When it finishes, it will create a folder called laravel in htdocs with the following structure:

Finally, restart Apache From Xampp Control Panel:

Success!

Finally, Open your favorite browser and navigate to http://lara and Laravel it's installed!

Should you encounter any challenge is installing the framework, please drop it at the comment otherwise, say hello everyone!

A Triple-G Programmer

Triple - G or 3G Programming - Latest Trend in Software Development

For the past couple of days, I have been asking myself, What does it take to be a G-Programmer?
I know by now you buzzer is on -"What is G-programming in the first place?" If you asked that to yourself, then you are in the right place. Then let me place by assumption about you on the table:

• One - You are a programmer or perhaps, interested in programming
• Two - You are interested in programming trends
• Three- You want to have little fair share of the multi-billion dollar industry or at least stay relevant.

Without calling a delay() subroutine, let me answer the first question:

What is Triple-G Programming?

G for Global

 This is programming that me address a particular aspect of society be it health, education, business, etc but has a global appeal. Global here implies the application cut across region and religion, language and culture, race and gender, desktop and mobile and wearable, static dynamic and AI. Global here also means open ie " pro- open-source". Global also means the application can be accessed by other applications and users can push the barriers of applicability.

G for Green

This is programming that is not necessarily limited to promoting the green revolution  nor address renewable energy challenges but by itself, intrinsically, green in terms of code efficiency. The application respects the EMC (Electromagnetic Interference / Compatibility) policy - to be and let others be, being economical and considerate n processor and memory and power usage. It should have minimum footprint. Of course it should help using reduce carbon footprint.

G for Godly

Undeniably, programmers are first of all humans. In a bit to increase human ease and/or decrease human dis-ease, we develop various applications. Programmers are creative, lovely and logical beings. Developing any software that will hurt or harm humanity isn't G-programming. Man would be a savage beast without the godly factor - believing it or not. This prints to the debate the ethics of cyborgs and the production of AI killing machines already in production.Programmers should not be the ones to arm politicians with weapons of mass murder like Nuclear Physicist and Biochemist did in the 19th century. I can't agrees any less with Elon Musk (CEO of Tesla and SpaceX) when he said, according to Washington Post,  "With artificial intelligence we are summoning the demon."

Implication of Triple - G Programming

Game

Unlike other programs games carry the widest usage. The games could be very challenging, yet that doesn't hinder is appeal. It is very interactive and addictive. Programming should start looking at every software as a game. When adapts the  game model we have a good "Adaptive Learning" experience - student centered, interactive, performance monitoring, immediate feedback. The gaming model is also seen in Network Marketing, Betting etc.

Go Programming

*A 3G programming language if Golang.  It is a compiled, statically typed,  memory safety  and  concurrent language with garbage collection, limited structural typing. Go takes advantage of , and adapt to the needs of current and emerging trend of cloud, distributed, AI system etc. To all 3G programmers, get Go-ing is not optional

Google Service

I need not say much about this Giant we all know. google has provided tools and service for developers to leverage 3G Software Development:

Firebase:  Firbase is a mobile and web application development, deployment and post-deployment monitoring and management platform. It greatly reduces developers stress about back-end and let them focus on front-end development challenge.  Firebase offers Realtime Database, Crash Reporting, Cloud Firestore, Authentication, Cloud Functions, Cloud Storage, Hosting, Test Lab for Android, Performance Monitoring and other services. 3G developer should ionic his base with some fire!

Actions on google and API.AI: 3G-Programs apart from guaranteeing users data privacy and security also enhances users freedom. Apps for the Google Assistant ensures that freedom developed using Actions on Google. They are conversational in nature and let you extend the Assistant's functionality with your own conversations that let users carry out their intentions through API.AI. Applications that lack this feature will be soon be fading out gradually.

General

G-programmers are generals or are becoming one. "Generals" here is borrowed from the military register. To become great programmer or  g-programmer is going to take discipline. It implies being the best you can be and not half-baked. Not being contented with a program you know you could make it even a little bit better.
As a g-programmer, you must have general knowledge (not expert knowledge) but at least fundamental knowledge in every category of the IT city (ICT). That would make a general know which special-force division to assign for a particular operation. My arrangement may be inexact but the idea is, have a knowledge of each category.

SN	Category	Language/Framework/Service
1	Web App (back-end)	ASP, PHP, Dart ( + Frameworks)
2	Website (front-end)	HTML5, CSS3, JS, Bootstrap4
3	Progressive Web. App	Angular, Dart
4	Scripting	Typescript , Python, Ruby-on-Rails
5	JS Framework	Ajax, JQuery, Node
6	Mobile App	Android, Ionic, PhoneGab, Flutter, Swift
7	Google Services	Firebase, API.AI (Action on Google)
8	Desktop/ Enterprise	Go, Java, C / C++, C# .Net
9	Database	MySQL, SQLite, Oracle, MongoDB, SQLSever, PostgreSQL
10	Modelling, Simulation	Matlab, R
11	Microcontrollers Programming	Arduino, Raspberry

A g-programmer is jack of all, master of some

Yes! A g-programmer must be an expert in at least one programming language but apart from that, as a g-programmer, you are also a good team player exhibiting good leadership quality and interpersonal skill with other professionals. Get involved in Stackoverflow, Github, etc and share. As a 3g-prgrammer, taking part in the (global) developer community and making contribution in any little way is a hobby.

Aaron Hillel Swartz

Give: Finally, a g-programmer is an activist supporting a noble course always such as freedom, human-right, charity, etc. Programmers are the most logical set of people thanks to their daily practice. And the logic of the heart is charity.

Conclusion

The world has becoming a global village and continues to evolve and software developers who seems to be the pace settings must evolve with it. The evolved programmers of the generation are 3g-programmers whose works must be godly, green and global; whose experience must be general and holistic all with the every constant objective is to increase human ease and/or decrease human dis-ease as man expands his frontier in our universe.
