Python Class Attributes: An Overly Thorough Guide

This article is originally published at Toptal.

I had a programming interview recently, a phone-screen in which we used a collaborative text editor.

I was asked to implement a certain API, and chose to do so in Python. Abstracting away the problem statement, let’s say I needed a class whose instances stored some 

  <td>
    <div class="text codecolorer">
      data
    </div>
  </td>
</tr>

 and some 

  <td>
    <div class="text codecolorer">
      other_data
    </div>
  </td>
</tr>

Rails Service Objects: A Comprehensive Guide

This post was written by Amin Shah Gilani, Ruby Developer for Toptal.

Ruby on Rails ships with everything you need to prototype your application quickly, but when your codebase starts growing, you’ll run into scenarios where the conventional Fat Model, Skinny Controller mantra breaks. When your business logic can’t fit into either a model or a controller, that’s when service objects come in and let us separate every business action into its own Ruby object.

Display IP address in console login screen

Here is one liner that will add the current IP address in the console login screen (if you are not running X as is case for servers):

(ip -o -4 a| awk '$2 !="lo" {print "\nIP Address ::"$4}' |tr '\n' ',';echo)>>/etc/issue

Just execute the above command as root. It will add the required code in “/etc/issue” to display the IP address. BTW, you can also use “\4” or “\6” instead of that command to get the IP but that will not work with some old versions of Linux.

Port php mysql scripts to php 7.0 from 5.x version

Recently I got a script or series of scripts that were written for PHP 5.6x and hence used mysql_connect which as you know by now does not work with PHP 7.0. Since there were number of scripts, I thought it would be waste of time to change them manually and wrote a script to fix them. If you have similar situation then probably this few lines could help you.

Since my scripts did not use all the functions so I did not put the sed commands for all of them but you get the idea 🙂
