• Miguel Grinberg ☛ How to Host your Own Email Server

  I recently started a new platform where I sell my books and courses, and in this website I needed to send account related emails to my users for things such as email address verification and password reset requests. The reasonable option that is often suggested is to use a paid email service such as Mailgun or SendGrid. Sending emails on your own is, according to the Internet, too difficult.

  Because the prospect of adding yet another dependency on Big Tech is depressing, I decided to go against the general advice and roll my own email server. And sure, it wasn't trivial, but it wasn't all that hard either!

  Are you interested in hosting your own email server, like me? In this article I'll tell you how to go from nothing to being able to send emails that are accepted by all the big email players. My main concern is sending, but I will also cover the simple solution that I'm using to receive emails and replies.

• Hackaday ☛ Linux Hotplug Events Explained

  There was a time when Linux was much simpler. You’d load a driver, it would find your device at boot up, or it wouldn’t. That was it. Now, though, people plug and unplug USB devices all the time and expect the system to react appropriately. [Arcanenibble] explains all “the gory details” about what really happens when you plug or unplug a device.

  You might think, “Oh, libusb handles that.” But, of course, it doesn’t do the actual work. In fact, there are two possible backends: netlink or udev. However, the libusb developers strongly recommend udev. Turns out, udev also depends on netlink underneath, so if you use udev, you are sort of using netlink anyway.

  If netlink sounds familiar, it is a generic BSD-socket-like API the kernel can use to send notifications to userspace. The post shows example code for listening to kernel event messages via netlink, just like udev does.

These are some of the ls command's most useful options.
