Encrypting your home area for backup with Openssl | using openssl to encrypte and automate your backups to fileserver

Im currently running a Linux desktop, the other day the disk become corrupt and I lost my home area. Not a big problem as I dont store much data, but I lost all my ssh keys, configs etc. It took a few days to recover.

In an effort to stop that from happening again I want to backup all my data to the company file server, but I dont want them to have access to my keys and configs ect.

So I have scripted a backup which will encrypt on the fly. Through it into cron and you have a daily backup.

This is the command you run to create backup, notice the password is in the command. This is allow for automated backups using Cron.

And the following command is to run a restore, once executed you will be prompted for the password.

Building a Apple Macbook Powerbank | apple macbook powerbank charger

Iv been looking for a powerbank for my Macbook Pro for years. I managed to find one years ago at the price of $300, too much.

I recently purchased a powerbank from ebay and noticed it has a 15 volt option, considering the Macbook chargers are 16.5 volts it should have enough grunt to charge it.

The only component I ordered was the custom Apple cable. Here is the shopping list.

Ok, lets get started with the project. This project can be completed by a beginner, its not complex at all. You just need to ensure its completed correctly as it may cause damage to your Macbook is connected incorrectly.

So i found a Coaxial power cable in my garage, this is the cable connected to the powerbank. We need to fuse this cable with the custom Apple charge cable.

Once we connect the two, we must ensure we seal them correctly using some shrink seal.

I finished and connected it to my Macbook Air 11″, worked straight away. You must ensure that positive and negative is connected correctly. This is achieved by using a multimetre.

When you have completed the project before connecting to your laptop, using a multimeter compare the created cable with the power adapter. You should achieve readings like this.

If your happy with the results then you can connect it to your laptop, you should see the green light which will then turn to orange indicating that its charging.

Results?

Im really happy with it. I did a test of it charging capabilities. I charged the powerbank 100% and then connected it to my Macbook Air which had 15% charge. It charged it to 48%. Its probably around an extra hour of operation on the Air. Enjoy!
