Linux Mint 20

๐Ÿ“… July 13, 2020
Linux Mint 20 was released a few weeks ago, and, after installing and exploring its features, I can say that version 20 is another fine release in the series and one of the best Linux distributions available for everyday usage.

Here are a few of my thoughts.

EVGA RTX 2080 Super XC Ultra Review

๐Ÿ“… June 27, 2020
The 2080 line of graphics cards has been available for a while, so there has been time to see what these cards are capable of.

Recently, I had the opportunity to try the EVGA RTX 2080 Super graphics card for myself in Linux and Windows systems. The result was impressive (in Windows) and not so impressive (in Linux) at the same time.

How can this be? Here are my thoughts.

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.

๐Ÿ“… May 13, 2020
Python 3 provides a handy module, argparse, that makes it easy to get and parse command line arguments passed to your script.

If you ever found argument parsing to be a tedious extra, then argparse might be just what you were looking for to simplify the process and focus on your code.

Vivaldi 3.0 Released

๐Ÿ“… April 22, 2020
The free Vivaldi web browser has been one of my favorites over the years, and the latest version 3.0 is a worthwhile upgrade that preserves everything I like while adding improvements.

After using version 3.0 for a little while, it has proven to be just as reliable as previous versions. Most notable is the new tracking and ad blocking privacy feature now built into the browser itself!

That’s right. There should not be a need to install a third-party ad-blocker anymore.

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!

How to View Graphics Card Info in Bash

๐Ÿ“… March 12, 2020
“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.

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.

Bash IFS – What is the Internal Field Separator?

๐Ÿ“… February 16, 2020
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?
