My Experience With Programming by G S Rao

Prepare your  github  repo on /var/www folder to follow the best practice. $cd /var/www Create a source code folder with your application name $ sudo mkdir <Project Name>.com Create a folder for github source code $ sudo mkdir <Project Name>.com.git Change to project github repo folder $cd img-cloud-qa.com.git/ Initiate github bare to prepare folder $sudo git init --bare Jump to  hooks  to prepare your hooks for git preparation of project so you can start pushing your code to github. $cd hooks Now we are ready with hooks set to your project, create a post-receive file to execute your steps with shell script, below example is a node project and i am doing npm install and restarting web server. $sudo nano post-receive #!/bin/sh error_exit () { echo "$1" 1>&2 exit 1 } git --work-tree=/var/www/<Project Name>.com --git-dir=/var/www/<Project Name>.com.git checkout -f cd /var/www/<Project Name>.com || error_exit

This will work for Rails 3.x onwords Model.skip_callback(“create”,:after,:trigger_my_method) in the above line ‘create’ and ‘after’ represents callback name so it represents ‘after_create’ callback, and the callback method is ‘trigger_my_method’, so totally the above line skips below callback after_create :trigger_my_method You can skip validations just by passing :validate =&gt; false as parameter to save method Model.save(:validate =&gt; false) As before skipping callback, you can reset same callback for reset by below ling Model.set_callback(“create”,:after,:trigger_my_method) This line will reset the below callback after_create :trigger_my_method Example:- Skip callback and validation and  rest the skiped callback Post.skip_callback(“create”,:after,:trigger_my_method) post=Post.new(params[:post]) post.save(:validate =&gt; false) Post.set_callback(“create”,:after,:trigger_my_method)

cat = String . new ( "cat" ) def cat . speak 'miaow' end cat . speak #=&gt; "miaow" cat . singleton_methods #=&gt; ["speak"]

Question :  I have reset factory settings, reboot my modem, pc, clear cache, etc. still its not loading facebook but will load any and all other websites. When i bypass the router, connect directly to my modem, facebook works. why is this happening? Solution :  It is because of TCP packet size for that we need to change the MTU size of our tcp connection, below commands will help to do that $ifconfig  above command will display the available networks with name and if addrsss Ex:- $ifconfig eth0      Link encap:Ethernet  HWaddr b8:ca:3a:d4:63:1d UP BROADCAST MULTICAST  MTU:1492  Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B) lo        Link encap:Local Loopback inet addr:127.0.0.1  Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING  MTU:65536  Metric:1 RX packets:776 errors:0 dropped:0 overruns:0 frame:0 TX packets:776 errors

In ROR working with multiple databases ( Mysql + MongoID or Postgres + MongoId ) for performance is good, but how can i give default generator database to pick-up while generating the models edit  application.rb  in config folder and add below code config.generators do |g| g.orm             :active_record end So every time in next generators will take active record as default for moddels In case of using mongoid and active record this will be helpful
