Git HowTo: revert a commit already pushed to a remote repository

Revert the full commit

Sometimes you may want to undo a whole commit with all changes. Instead of going through all the changes manually, you can simply tell git to revert a commit, which does not even have to be the last one. Reverting a commit means to create a new commit that undoes all changes that were made in the bad commit. Just like above, the bad commit remains there, but it no longer affects the the current master and any future commits on top of it.

git revert {commit_id}'

About History Rewriting

Delete the last commit

Deleting the last commit is the easiest case. Let's say we have a remote origin with branch master that currently points to commit dd61ab32. We want to remove the top commit. Translated to git terminology, we want to force the master branch of the origin remote repository to the parent of dd61ab32:

Installing Kerberos on Redhat 7

This installation is going to require 2 servers one acts as kerberos KDC server and the other machine is going to be client. Lets assume the FQDN's are (here cw.com is the domain name, make a note of the domain name here):

Kerberos KDC Server: kdc.cw.com

Octave - find the min (or max) value of a Matrix, and the associated row and column

Whilst working through the many (Octave) coding assignment from Andrew Ng's Stanford Machine Learning course, a common problem that I have to solve revolves around this:

Given a Matrix A with m rows, and n columns find the mininum (or maximum) value and the associated row and column number

This article summarises my solution to this problem (which, hopefully this will also come in hadny to you!). Note that Octave index start from 1 (instead of 0).

Sample Matrix

Say we have a Matrix A that look like this:

Crawling Anonymously with Tor in Python

adapted from the article "Crawling anonymously with Tor in Python" by S. Acharya, Nov 2, 2013.

The most common use-case is to be able to hide one's identity using TOR or being able to change identities programmatically, for example when you are crawling a website like Google and you don’t want to be rate-limited or blocked via IP address.

Tor

Install Tor.
