Linux Mint offers some of the best-looking wallpapers of any Linux distribution or operating system, but there are times when you might want to add your own images for display at the login screen.
Whether it be a matching theme or your favorite vacation pictures, you can share the joy and ensure every user will see your images during local login.

What’s this? You installed Linux to a speedy M.2 NVMe SSD but boot times are not as fast as expected?
It might be a software issue. When Linux boots from power on, it runs a number of services before you ever see the login screen. Some of these services have timeouts and increase delays. Other services might be completely unnecessary, but they are loaded during boot anyway.
By disabling unneeded services, the Linux boot time can be reduced by a few seconds.

Anonymous FTP is a handy way to provide public files to users over a LAN. Any user may log in to the FTP server without requiring an account on the FTP server itself. Just log in as anonymous and download.
But how can we set this up?
In this quick tutorial, we will see how the process works and what configuration settings must be made for a read-only anonymous FTP login.

“Can I use RapidDisk with VeraCrypt?”
Absolutely. If you have an encrypted volume with VeraCrypt, you can easily add a RAM cache to improve read performance.
The setup is the same as with a regular RapidDisk cache but with an added extra step to map the VeraCrypt volume.

Do you have some extra RAM in your system?
Want better read speeds from slower mechanical hard drives?
How about adding a RAM drive to your system?
RapidDisk is an open source tool for Linux that enables you to create RAM disks for general purpose usage or use them as caching systems for existing hard drives.
I have been using RapidDisk myself on desktop systems, and I can say that it greatly improves the read performance of slow hard drives whether they be single drives or RAID arrays. You can even set up a RapidDisk RAM cache for a USB device. RAM disks are surpringly useful despite being volatile. Best of all, RapidDisk is free to obtain and simple to use after a little reading.
Here is how to use RapidDisk in Linux Mint 18.1 in a simple configuration so you can experience faster read speeds from your hard drives.

Do you have a few spare network interface cards?
Want to increase your local network throughput and handle more traffic?
Link aggregation, or bonding, is a technique that combines two or more network interface cards (NICs) into a single virtual network interface for greater throughput.
For example, two gigabit NICs result in 2 Gbps throughput. Three gigabit NICs allow 3 Gbps throughput. Four allow 4 Gbps, and so on. While these are theoretical maximum values and other factors affect network transfer rates, the point is that multiple network cards acting as a single “card” can transfer more data at a time. As an example, more users can access the same server simultaneously without seeing any noticeable drop in transfer speeds.
Linux supports link aggregation out of the box with only a few modifications. Regular, inexpensive network cards and switches can be used, so there is no need to purchase expensive, specialized hardware. This allows you to reuse existing hardware that you might already have on hand. And yes, it works well.
While link aggregation has worked in the past, newer Linux distributions tend to change a few things, so older setup techniques need revision. This is the case with Linux Mint 18.1. For details regarding the benefits of link aggregation, please have a look at the article describing link aggregation in Linux Mint 17 and Xubuntu 14.04 (July 12, 2014). The information is still relevant.
Link aggregation works well in Linux Mint 18.1, but a few changes are needed in order to make it work. However, it is easier than expected!

The timezone setting (tzdata) determines how time is displayed on a Linux system. This is specified using a location string, and we can change this string to set a system’s timezone to any timezone on the planet.
