As you recall from the previous blog post, I’d installed Unity and JetBrains on my Fedora 32 computer via Flatpaks. I was going to use them for the Unity Multiplayer course I was taking on Udemy. Unfortunately it was an immediate fail and in lesson one after they have me install a new inputs library and restart Unity, it would always crash upon loading the file. I’m currently installing Unity 2020.1 on my Windows computer where I don’t expect to have that issue. Assuming I don’t, then it’s a big fat nope on using Unity on Fedora via Flatpak (at least for this class). Which, to be fair, is not on their supported OS list - which is only Ubuntu and CentOS 7. (And the latter for movie-making)

As I mentioned last year in my 2019 in Programming post, I created a bunch of 2D games in Unity by following along with the Gamedev.tv classes. I would watch the videos on Linux and jump over to my Windows computer for the programming, learning how to use SourceTree and Microsoft Video Studio in the process. But for some reason, going back and forth with the KVM when running Unity would sometimes freeze up the Windows computer. So when I saw someone on Fedora Planet running Unity Hub, I thought I’d see if there was a Flatpak - and there IS! Also, I’ve fallen in love with JetBrain’s Pycharm, so I thought I’d go ahead and use their game dev IDE, Rider. ( There’s a Flatpak for that, too!) So, let’s see how well this works!

I just found out today that PyGame 2.0 was released yesterday, on the 20th anniversary of the software. One of the first steps I took with Python was a series of games I made from tutorials in Linux Format Magazine. On Github I’ve got my shifter game and my Space Invaders clone. The shifter game is a little wonky since I haven’t touched the code in over a decade. But I was able to make the one shift needed to make the Space Invaders clone work on Python 3. So you can enjoy those and celebrate that PyGame development has picked up steam again.

It came out this Tuesday and last night I updated my laptop. The only thing I had to do for the upgrade was remove a python3-test package. Since I’m using virtual environments, for the most part I don’t care which Python packages the system has. So that was a nice, easy upgrade! Good job Fedora packagers and testers! Speaking of Python, it’ll be nice to start upgrading my projects to Python 3.9. (Fedora 33 includes the latest programming language versions as part of its “First” values)

Selenium for Automated Pool Signup

Spent the last week debugging that script. Turns out the key to getting it to run in cron is to add export DISPLAY=:0 && before your command. That’s because Chrome will not launch without a display to send Chrome to.

Python Morsels

The most recent Python Morsels exercise was to figure out if a number was a perfect square. Trey began his problem statement this way: “This week I want you to write a function that might seem simple at first, but there’s a number of ways to solve it.” It definitely took some out of the box thinking for me to figure out how I was going to solve the base case. The math.sqrt() function returns a float so that it can give answers for non-perfect squares. So I kept thinking and I realized that any perfect, non-complex square root must be an integer. So I came up with the conditional to return. (And after all this Pythonic learning, I’ve learned not to evaluate for truth and then return a variable. Just return the evaluation)

And failed and left my site offline most of the day. So I’ll have to try some stuff on the side and give it another shot.

I just moved this blog to slightly different hosting infrastructure. Because of that I had some funky issues with character encoding yesterday. I believe that’s fixed now, but there may be other things that take me time to notice and fix up. Also, I still have a couple other things to set up so that I can FINALLY have https working for this blog. As part of this infrastructure change, I discovered and fixed at least one long-running issue that was causing problems with that. So if things are offline for a bit over the next few days or weeks - that’s why.

Been quite busy with Python, keeping me away from other pursuits, like video games. (Although the kids have been requesting Spelunky 2 whenever it’s time to hang out with them)

Extra Life Donation Tracker (eldonationtracker)

For my Extra Life Donation Tracker I pushed out a new release, v5.2.2. A user of my program (man, I never get tired of how awesome that is!!) had wholly anonymous donors which was causing an issue I thought I’d handled. But it turns out that the folks that run the Donor Drive API are a little inconsistent in how they handle that in the donor endpoint vs the donations endpoint. So I pushed that fix out and now things should be dandy for game day (about 2 weeks away!!)

It took me a while to get the hang of the many, many options within Podcast Republic so that I could get it to work the way I wanted - automatically downloading episodes on WiFi. Unlike Doggcatcher, but more like other modern pod catchers, you can stream a podcast instead of always having to download it. The option is nice, but it does introduce complexity. As usual, it was annoying at first to have the pod catcher think it needed to download every single episode from the podcasts you subscribed to.

I’ve been using Doggcatcher for YEARS - ever since I first got a smartphone something like 8 or so years ago. I started using Doggcatcher on Dan’s recommendation. One of the best features it’s had is the ability to speed up podcasts without chipmunking the voice. (I think that came a year or so after I started using it). Recently I’ve been a bit annoyed at Doggcatcher, particularly with podcasts from the EarWolf network (although there may be other networks with the same behavior). Every time Doggcatcher checks for updates, all the episodes from EarWolf will disappear and redownload. Until it is done, I can’t listen to the episode.
Neil deGrasse Tyson’s podcast is also annoying in that if a new episode comes out before I’ve finished the previous one, it’ll overwrite it so that I now have two copies of the same file. This makes it more stressful than it needs to be when I’m trying to choose the next podcast to listen to. So I started asking folks for recommendations. Dan recommended Podcast Republic to me. I don’t know if it’ll fix things for me because Dan was using it because Doggcatcher wasn’t working well for him for authenticated feeds, but I’m hopeful.
