Quick Post : Yii Boostrap theme integration

For this you need to create a Yii project and then clone theme into its themes folder...

We need yii framework zip downloaded and extracted at some location and LAMP/MAMP/AAMP etc. preconfigured.


This can be done by using following commands

php yii-1.1.16/framework/yiic.php -webapp development/phpProjects/yii/boostrap3Theme

cd development/phpProjects/yii/boostrap3Theme/themes/

git clone https://github.com/amnah/yii-bootstrap-starter-theme.git

We need to configure the theme in configuration of app i.e. main.php located at protected/config/main.php location.

It does not have theme parameter added by default we need to configure it by adding 'theme'.

Before

return array(
 'basePath'=>dirname(__FILE__).DIRECTORY_SEPARATOR.'..',
 'name'=>'My Web Application',
 'theme'=>'yii-bootstrap-starter-theme',

After

return array(
 'basePath'=>dirname(__FILE__).DIRECTORY_SEPARATOR.'..',
 'name'=>'My Web Application',
        'theme'=>'[yii-bootstrap-starter-theme]',

Finally we need to setup up this config in views i.e. protected/views/layouts/main.php

<?php
        $bootstrapVersion = "3.0.0";
        $fontAwesomeVersion = "3.2.1";
        $jqueryVersion = "2.0.3";
        $queryUiVersion = "1.10.3";
?>

Getting started with GAE - Python on codenvy.io - Part 2

Continuing my earlier post here...


We had reached to a default application being created by codenvy as template to get started.
I will try to shade some light on this default application also share a backup of the source code for JUST IN CASE situations here.

Attached source code


Your workspace allows you to have multiple projects in it; we here are now looking at a sample that covers basics of app engine in one example.

During my learning curve all this application has was divided into seven steps now world being fast I believe this one shall suffice.

Running the application:
Your application is already coded ready to run with codenvy just click on source folder and press play you application shall start. There will be url at bottom shown in logs click on it to view your output.

DASHBOARD VIEW

 OUTPUT AFTER CLICKING ON LINK

List of concepts to look for to understand about source code:

• Checkout app.yaml
  This file gives you entire configuration of your app including directory structure and URL mapping
• Open and study guestbook.py
  This is your core logic study it thoroughly like an OOP case study (bottom up). All routing and business logic is mentioned. Study libraries needed to include
• Concepts covered
  URL Pattern to Class mapping
  Handling requests
  Classes / Libraries in order for reference : Jinja, webapp2, ndb, and Users
• Google plus social sign in and verification

Getting started with GAE - Python on codenvy.io - Part 1

Recently I was helping a  fellow developer to get started with online IDE so that I can share my experience of developing with wonderful Google Cloud Eco System. As usual offline setups were complicated for entry level developer to get started so I decided to turn on to my till then favorite c9.io.

Now here's the problem, when will you corporates understand the epidemy of a student or starter level devloper looking for learning. C9.io has now made credit card verification mandatory for new users.

So here I am going forward with my then second now first favorite cloud IDE codenvy.io...


Steps to get started are now shared below.

1. Sign in using github
2. Enter details
3. Dashboard looks like this
   
4. Next find your GAE python option in the same page by scrolling
   
5. Next enter your project / workspace details to get started
   
6. And now you see your workspace starting up for first time with a simple project; which looks like this
   
7. Now everything is setup and ready to roll: see you in follow up post

Kompozer install(ubuntu) and quick review

Ubuntu Kompozer install command:

sudo apt-get install kompozer

Official website : Click Here

After installation on opening Kompozer you will see a tooltip which you can ignore to continue. Next screen shall be as follows, I am numbering items in image to explain them in short in table that follows:

First Screen on opening Kompozer

As a beginner, one should be acquainted with these 5 options at first.

Item Code	Short Description
1	Design View : Potrays output as you will see, this is also a WYSIWYG editor where you can directly start editing and relevant HTML witll be generated
2	Split View: Here you see part of HTML  code at bottom of screen and design on top so that you can edit any to get the desire look and feel
3	HTML view: HTML is complete source code view of document with code highlighting functionality for web developer
4	Quick access menu: You are provided with mostly used items on the top so that you can add edit delete most used HTML tags easily. Most of them also have wizard to help you figure out what is to be done
5	DOM explorer: Have you ever imagined a tree with branches and sub branches to its twigs. Well HTML document follows that kind of structure where in everything is inside html tag but could be explored in tree like structure using DOM explorer

You can use this tutorial as base and try to design a webpage in this another post as a start : Next post

Posting my experience with Logitech K480

How did I get it?
I was like always checking out deals on different sites, just when this lightning deal(amazon) caught my attention which said K480 for 1899INR and I knew I had never seen this any less 2500 on different occasions so I had to book it :P
Unexpectedly delivery charges were free and it said will be delivered in two days but got delivered the next day!

Initial impressions (day 1: more like working day 1)
First of all its heavy but I guess it gives it sturdy ness.
Setup with android devices was pretty easy just for new buyers if asked for pin type it using keyboard and press enter it works that way.
The main problem I faced was with windows. Initially it connected like a charm and I did some shortcuts and it worked but once I changed device using keyboard; windows 7 setup was dead! No matter what I do it was dead. I tried remove device and that caused me to hit a dead end - now keyboard is not even shown in search new device.
PS: I have done driver uninstall/ install, couple of reboots, service log on changes, registry key changes for that sake; its still a dead end for K480 with win7.

Hoping to find a solution soon.

Impressions continued day 2
Keyboard gave me hard time today connecting to my phone, actually my phone was the only device which accepted it how it was in no time. I turned on my phones bluetooth and then turned on keyboard, it didn't connect on itself. I thought it might be some sequence issue so I switched between devices still same. I had to search and add this keyboard to phone again.
I wonder what went wrong between these two :P

Note for readers: This post is posted from my Lenovo K3 Note and my brand new Logitech keyboard K480 (which i haven't paid for it yet :P)

Quick shell based network setup [linux]

By default most linux OS have their network config set to DHCP. How to change it and get going with custom settings.

This is what DHCP setting looks like

auto eth0
iface eth0 inet dhcp

For same we need to edit interfaces file as following:

sudo vi /etc/network/interfaces

Contents of file considering we are editing for eth0 card

auto eth0
iface eth0 inet static
address 192.168.2.1
netmask 255.255.255.0
gateway 192.168.X.X
dns-nameservers X.X.X.X Y.Y.Y.Y Z.Z.Z.Z

After saving above configuration we need to restart networking service to apply changes

 sudo /etc/init.d/networking restart

Checking of new configuration can be done as follows

$ ifconfig eth0
$ ifconfig

Navigation / Menu (Dynamic) using bootstrap

Point to be noted is that bootstrap has already taken care of different screens so when you are coding the bootstrap page its dynamic to screen size. This post covers one  of such amazing example where you design a navigation for large screen and it automatically becomes collapsible for mobile screens.

Here is the code,

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72

Output:

DESKTOP/ LARGE SCREEN 

Desktops/ Large screen devices

MOBILE/ SMALL SCREENS 

Explanation:

Note that I have intentionally included jquery before bootstrap js inclusion becoz if not done so dynamic navigation fails to expand and collapse 

Line 15: If you change navbar-default to navbar-inverse you shall have dark theme
Line 25: href value defines what is to be done when clicked on Logo or brand name
Line 26: uncomment it and set company logo here if you want

Layout / Grid system in Bootstrap

Bootstrap divides page as mainly usable and not used part by mentioning class name as container for div tag.All the content we need to show is inside this div tag

This container is then divided into 12 equal parts indicating a block of layout. Basic concept of layout is a tabular structure. But tables have drawbacks in layout as we cannot overlap table on each other and it is very strict with columnar and row-wise structure.

Here bootstrap we use this 12 parts scheme to layout our visual components in a div with class name row

and each unit we show has class name starting with col-[+]-[*]

Note:

[+] here indicates values as lg(large screen), md(lappy/desktop), sm(tablet), xs(mobile)

[*] here indicates value from 1 to 12

One thing to understand here is that the value you set for one component should be either 12 or components in row(div) should addup to 12

Lets say layout we wish is two column for desktop display the code will look like

1 2 3 4

<div class="row"> <div class="col-md-8"></div> <div class="col-md-4"></div> </div>

This will divide page to give output somewhat like in image below:

Getting started with bootstrap [setting up]

Git go to any moment (commit) in time

Get this straight you are accessing repo thats already setup and has commits branches etc in it


Here's how you go to any period of commit in a repo status
Git repo url :  https://github.com/thatsmekaustubh/appengine.git
You start by cloning it in your working directory

git clone https://github.com/thatsmekaustubh/appengine.git 004appengine

To know all commits you can find it using this command

git log

To know all branches you can find it using this command

git show-branch -a

This shall give a picture of all flows of development
this in present moment of time is

start__masterBranch
      |__experimentsBranch

Commits were

• false commit (hello world example)
• Hello world example with commmand to run
• Users API example 

The command shows

git log

all commit id's

You can switch between branches as

git checkout <branchname>

And go to particular commit by saying 

git checkout <commitid>

Github getting started

Account Part:
Signup to github and then login
once logged in you will see my repo in which you should click on Create New Repository
    Fill in details and say create
On the machine you wish to code and submit changes to github you need a SSH key setup on both peers (mentioned in another tutorial)


Coding Part:
Say,

git init 

on your code whereever it is

Code your files (Note: that you are on master right now) [detailed post on branching and merging]

To add all changes say

git add --all

(this stages all non-committed files)

To commit say,

git commit -m 'Your message for the commit'

Syncing part:
You might want to sync this changes to github website so,
Type this 

git remote add origin https://github.com/<username>/<reponame>.git

To send commit to server type

git push --all

This shall get your code on git hub open repository to be shared with all

Setting up c9.io (ubuntu) with Google App Engine SDK - PYTHON

I try to cover as much of steps required as possible in my posts but dont include them all in one post so that one doesnt get bombarded with information. Please refere to pre-requisite section with reference sufficient for you; if it doesnt exist please mention so in comment.


Pre-requisite :
c9.io account
Create a workspace with Python Config

STEPS:
Go to shell copy paste one at a time

STEP(1)	Get SDK from Google to you c9.io workspace wget https://storage.googleapis.com/appengine-sdks/featured/google_appengine_1.9.40.zip
STEP(2)	Unzip the sdk package unzip google_appengine_1.9.40.zip
STEP(3)	Set path variable for future reference export PATH=$PATH:/home/ubuntu/workspace/googleAppEngineSDK/google_appengine/

Reference : Google Docs

Creating Sheet using Google Drive Excel (Shared Manner)

Step 1	Go to drive.google.com You need to login using your google account (xyz@gmail.com/ xyz@company.com)
Step 2	Click on new and select sheets
Step 3	Set any name at top where it says Untitled sheet and press save
Step 4	Next click on share to share it with any email id. Note: In case you are using company email id you can only share the document with other emails within company domain ex. xyz@company.com can share it with someone like abc@company.com and not abc@gmail.com (mostly.. exceptions can be added by company google account admin) Share can be done in one of three manner : readonly : where in other user can only read the document contents comment : where in other user can read and comment on the document contents edit : where in other user can read, commment edit the document contents There can be one more option for sharing sheet publicly with one of the above three manner. Which means any one with link can perform that specified operations. To do so you simply need to copy and message URL to your contact

Review Lenovo Note K3

Hey there folks, its been a week now for me using my new mobile Lenovo Note K3 and here is my feedback about it as a regular IT guy.

This phablet pretty much sums it all, you get a descent screen size and great computing power to do your daily tasks. Especially for guies like me there is a gud news you can comfortably code, read, watch videos and play games. Lenovo has taken a gud effort designing this phone keeping it sleek and yet functional not to forget at a reasonable price.

Heating problem? You must be a die hard gamer to face this issue. So far I barely experienced any heating issue, but when I did it was in top center on back of device (when I was not using any case)

Full HD is a real delight! I am enjoying watching my favorite videos on this device. Sound quality is pretty gud and obviously if you need to rock your house with sound you need a speaker it isn't the fault of device manufacturers that they haven't housed a home entertainment system in your mobile. I have enjoyed songs in room full of 15 people partying, on local station, on the road and other crowded places full of noise and quality is satisfactorily audible in adverse situations.

Camera on both front and rear are delight, we took a selfie in theatre which explains it all.

Functionalities
As a developer: Yes I am coding with this device, not just coding I am building  websites, and apps with this device. So you get the idea college students and lite coders.
As a commuter: Except for Virar Locals from Mumbai I can call this phablet as a handy device, to check schedules, read feeds, books, papers play games. Your hands wont get tired that easily.
As a reader: I haven't finished any book yet but have read a couple of journal papers on this device and it was comfortable.
As a Mobile User: I know its crazy but I am getting better cell reception at all places, this was unexpected from any smartphone as I always had to search and re search and choose network 4 times a day!

Bottom line: If you are any one else then a die hard gamer or a graphic designer (who draw - which needs stylus) or a person spending most of the time on voice calls this is a phablet/ smartphone for you; and trust me it cant go any better at this pricing.

Is there an app for that?

This is my first post in the series is there an app for that series of post !

What got me thinking is I know lot of technology stuff I use a latest android tablet compatible with pretty much every single app available there (obviously not all apps) and I face many odd needs with this tablet I use.

So I have decide to write a review of app that I use or come across and define its application.

Cheers to a new beginning!
