Keeping your MySQL server backup as current as possible is important. I’ve seen (and have done this myself) people backup using mysqldump once a day, week, or month without any backups in-between. There are a few problems with backing up your database this way. The first problem is that running mysqldump is very slow on large databases and could lockup your website for a significant portion of time. Secondly, you can lose all data that occurred since the previous backup.
This post is going to cover how to take a USB device and write software that can interact with the device without having publicly available documentation. I came about writing this post when I found an old AverMedia RECental USB button in a box of electronics. I wanted to repurpose the button and this is the result of that process.

There are times when you need to connect to your MySQL or MariaDB remotely but don’t want to enable remote connections on the server. The solution is to use SSH tunneling with OpenSSH. SSH tunneling works by forwarding requests from a client port to the SSH server. The SSH server will then forward the request to the destination which can be itself or any other host the SSH server can access.
SSH is the most valuable tool to manage your servers. As you already know, SSH allows you to remotely connect to your server and access a shell. With the power SSH possess, it’s important to protect SSH to ensure the only trusted people are able to connect. This post will go through the SSH configuration settings that need to be modified to help protect your server. Editing SSHD Configuration Files To prevent this tutorial from repeating itself too frequently, here is an overview of how to edit the /etc/ssh/sshd_config file.
Creating an envelope is most office suites only requires you to dive one or two levels into a menu. As for Google Drive, this just isn’t the case. It’s possible to change a Google Drive document’s page setup by navigating to “File - Page Setup”, but there are only eleven predefined paper formats you can choose from. To change the actual dimensions of the Google Drive document, you need to use a Google Apps Script that changes the documents dimensions.
