Programming the Logitech G513 RGB Keyboard Lights in Linux with g810-led

๐Ÿ“… May 21, 2020
The Logitech G513 RGB Mechanical keyboard has earned its place as the best keyboard I have ever used.

The keys have the best tactile approach, the build quality is superb with the metal top, the wrist rest is durable and soft, the size is convenient, the LEDs are confined to the key letters only (no light bleeding), and it just works with Linux.

But did you know that you can program each LED key individually with Bash to Python to create your own effects?

Do you want two random colors to be spread across the keys upon boot? Would you like a Pac-Man effect that pretends a yellow Pac-Man moves around the keys like a maze? Do you have different lighting patterns that you would like to assign to each user on the same Linux system?

All of this and more is possible with a free Linux program called g810-led that you can use with scripts.

TypeCatcher Font Picker

๐Ÿ“… March 25, 2020
“Is there an easy way to preview, pick, and install fonts?”

Yes!

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!

Customize Vivaldi Browser: Custom Speed Dial Thumbnails

๐Ÿ“… February 21, 2020
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.

Customize Vivaldi Browser: Match Vivaldi Wallpaper with Linux Desktop Wallpaper

๐Ÿ“… February 18, 2020
“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.

Intel NUC, Linux, Pi-Hole, and NAS โ€“ Part 7: Polipo Caching Web Proxy

๐Ÿ“… December 28, 2019
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!

Intel NUC, Linux, Pi-Hole, and NAS โ€“ Part 6: DLNA Using Emby

๐Ÿ“… December 4, 2019
Let’s add a DLNA server!

Casual users might not be interested in the “techie” features that we have installed on the NUC, such as SSH and FTP, so let’s install a DLNA server to make the NUC function as a media server for consumer devices connected on the same network!

With DLNA, users can connect and have access to pictures, movies, and music from their devices without logging in as FTP or SSH users. These devices could be cell phones, smart TVs, game consoles, or any other DLNA client.

To achieve this, we need a DLNA server. Multiple DLNA servers are available for installation, but we will install the free (basic version) Emby server for this project because Emby is easy to use, offers multiple users for a customized collection of media files, and offers a slick GUI for administration.

Ready? Let’s begin!
