LastPass Pwned Passwords checker

LastPass Pwned Passwords checker

This is a script for checking if any of the passwords you have stored in LastPass have been exposed through previous data breaches.

To use the script you need to have Python 3 installed and you need a CSV export of your LastPass vault. The export can be generated from the LastPass CLI with:

lpass export > lastpass.csv

or can be extracted with the browser plugin by going to the LastPass icon → More Options → Advanced → Export → LastPass CSV File (note that I did have problems getting this to work).

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:

Automatically backup a MongoDB database to S3 using mongodump, tar, and awscli (Ubuntu 14.04 LTS)
#!/bin/sh
# Make sure to:
# 1) Name this file `backup.sh` and place it in /home/ubuntu
# 2) Run sudo apt-get install awscli to install the AWSCLI
# 3) Run aws configure (enter s3-authorized IAM user and specify region)
# 4) Fill in DB host + name
# 5) Create S3 bucket for the backups and fill it in below (set a lifecycle rule to expire files older than X days in the bucket)
# 6) Run chmod +x backup.sh
# 7) Test it out via ./backup.sh

AWS Lambda Function to Delete AMIs and Snapshots
# Automated AMI and Snapshot Deletion
#
# @author Bobby Kozora
#
# This script will search for all instances having a tag named "Backup" with a value of "Backup".
# As soon as we have the instances list, we loop through each instance
# and reference the AMIs of that instance. We check that the latest daily backup
# succeeded then we store every image that's reached its DeleteOn tag's date for
# deletion. We then loop through the AMIs, deregister them and remove all the
# snapshots associated with that AMI.
