Fixed Opening SWF Files in Linux

I'm putting this up for future reference because the issue was driving me nuts. I very often use a flash timer when trying to budget my time on a computer. There is one in particular that I especially like from www.online-stopwatch.com which allows you to build a custom queue of alarms. That sight allows you to download the SWF file of almost all of their online timers, and this is useful to me because I can then run it simply by typing

 google-chrome --app=file:///location/to/swf/file.swf

at the command line. 

Except for recently. Lately, when I tried to open the flash-timer, chrome would try to just download it again. It took me forever to find the solution, but I finally came across it on an ArchLinux forum.

I've copied it here for redundancy.

Edit  /usr/share/mime/packages/freedesktop.org.xml and change

 <mime-type type="application/vnd.adobe.flash.movie">

to

 <mime-type type="application/x-shockwave-flash">

and then run

 update-mime-database /usr/share/mime

Worked like a charm after that. Apparently it has to do something with an update in freedesktop. Spent a bunch of time trying to find that solution, unfortunately. Well, at least its solved now...

Arduino & Tri-Colored LEDs

Image
I'm currently working on an unnamed  project which requires the integration of tri-color LEDs (RGB). These are merely four-pin LEDs with a common anode or cathode and an input pin for red, green, and blue. With varying currents, a multitude of colors can be produced. So I created a C++ (arduino) library for handling such LEDs. Since most of my knowledge of programming is in C, learning about classes in C++ is a significant accomplishment for me.

Nerd-Code Snippets 3: Bash Minecraft Install Scripts

Image
Nerd-Code Snippets 3: Bash Minecraft Install Scripts TL;DR - I haven’t posted in a while. I like scripting and I try to script my Ubuntu 20.04 setup whenever I can. While a bit silly, Minecraft, and a few other 3rd party programs that work with Minecraft, find their download/installation/upgrade scripts among my bash-scripted setup files. Yes, this old blog still exists, despite how sparse my contributions. However, now it is mid-2020, I’ve been at Synap for over 4 years, I’m married, have had back surgery, have a 1-year-old daughter, and – most importantly – I have recently upgraded to Ubuntu 20.04. As a part of upgrading to Ubuntu 20.04, I’ve decided to script as much of my setup and preferences as possible. While not a staple of my day-job at all, I do always have Minecraft installed on the Linux-side of my computer. The latest release, Minecraft 1.16, sees a huge update to the nether dimension. As a result, certain 3rd party programs are updating as well.

Solar Cell Characteristics

Image
So, a certain unnamed project that I am working on requires the use of a solar cell to charge some batteries. I got these solar cells from an "over-supply" store in Santa Clara for $4 a piece. As seen in Figure 1, its one of those typical solar cells from a garden lamp that charges batteries during the day and turns some LEDs on at night.
