“Is there an easy way to preview, pick, and install fonts?”
Hidden within the depths of the Ubuntu repository is a (probably) little-known program called TypeCatcher that allows you to preview, download, and install fonts directly from Google Fonts without needing to visit the Google Fonts web site at all.
Fonts can be quickly viewed and either downloaded to your computer or installed on your system with the click of a button. Talk about easy!

“What kind of graphics card am I using?”
If you write a script or log into a remote system via SSH, is it possible to discover what kind of graphics card is running on the system using only the command line?
Indeed it is!
In fact, we can use a variety of terminal programs to sift through the information, but we will look at three programs: lspci, lshw, and nvidia-smi.

After writing a bash script that matches the Vivaldi background to the Linux desktop wallpaper for a transparent effect, why not make the speed dial icons/thumbnails match as well?
Using bash and ImageMagick, we can modify speed dial icons to be monochrome, grayscale, color-adjusted to match the wallpaper, add a vignette, or almost any other image processing effect available. It depends most upon personal preference, so we will see how to set up Vivaldi and Linux to achieve this.

“How can I make the Speed Dial wallpaper in the Vivaldi Browser match the Linux desktop wallpaper?”
Vivaldi is a great free web browser, and it can customized in many ways for a user-tailored browsing environment. One such customization is the Start Page/Speed Dial wallpaper. One fancy effect is to make the Vivaldi wallpaper match the current desktop wallpaper for a “see-through” effect.
In Windows, this is easily accomplished within the Vivaldi Start Page settings, but in Linux, there is no such option, forcing us to set the Vivaldi wallpaper manually.
Is there a way to make Vivialdi match the current desktop wallpaper in Linux?
Yes, there is! It involves a little preparation and a bash script, but the result produces the same effect.

An internal field separator is a character (or set of characters) used as a delimiter to tell when a piece of data ends before reading the next piece of data.
Bash provides the environment variable IFS to store this special value. Why is this important?

Look at the colors!
The Mad Catz R.A.T. 8+ is a fine mouse that works well with Linux, so how can it be improved? Why, with a new color scheme, of course!

Let’s speed up web site access with a caching proxy!
With or NUC fully functional on a LAN, we can install a forward proxy to help speed up web accesses by caching the most common accesses locally.
The next time you or somebody else accesses the same site or downloads the same file, contents will be retrieved from the web cache stored on the NUC instead of downloading it again from the Internet. This can save bandwidth and make web pages seem to load faster in some cases.
One such proxy is called Polipo, which is an HTTP/1.1 proxy. It is lightweight and intended for a small group of users on a LAN, making this perfect for our NUC project.
Other proxies include Squid and Privoxy, which can be installed instead, but this article will look at Polipo.
Let’s have fun and see how to make this work!
