I wrote a post before regarding how I archive Zoom lecture recordings, whether I am teaching or someone else is. However, post-recording, those files sit in the vault unedited. It took a few months, but I discovered an issue with the audio in them. Funny. The times that I don't check audio prior to recording are the times it always goes wrong. It's Sod's law. With the audio messed up, and no chance to re-record, is recovery possible?

Let's analyse the situation. They are MKV files with a single video stream encoded via h264_nvenc. Ok, nothing wrong there. There's 3 audio streams saved as lossless FLAC. Here's the ffmpeg stderr output (yes, it goes to stderr) for one of the files:

Recently, a group of friends wanted to replay the Mega Man Star Force series. The Japanese version of the first game has some accessories that you can purchase to enhance your stats. One in particular, the Wave Scanner, caught my attention. So, I bought two of them. What does it do though?

It's a cute little device that lets you swipe real life battle cards in. Every battle card has a barcode at the bottom of it, so this device has a barcode scanner embedded. Battle cards may be used for the minigames that are on the device. However, the feature that caught my eye was that it can connect to your Nintendo DS/DS Lite/DSi via microphone jack and send battle card data over that. Now that's pretty cool.

My 42 TB storage is running out and Black Friday is around the corner. Deals are already out online. This sounds like a pretty good time for an upgrade. I need something that can last for a few more years. The plan? Same as the last time. Shuck external drives to get high capacity drives for cheap. Can't be a data hoarder without the capacity to store data, right?

Let's take a trip back for a sec, so we can compare past to present. Those WD (Western Digital) easystore drives have consistently been a nice way to get high capacity drives for cheap. Back in 2017, I needed more storage because some external 2 and 3 TB drives weren't enough. I wanted something overkill. Something that will last me for a few years. So I bought 4 of the 8 TB models for $160 each. That's just a bit above $20/TB when tax is considered. I have tweets with pictures covering these and what shucking them looks like. You can see those below:

As a University graduate student and teaching assistant, I have to attend and teach classes. Due to the events of the COVID-19 pandemic, classes have now moved mostly online. Zoom just happened to be the platform of choice where most classes are being hosted.

Back when I physically attended classes, I was that one student who sat in the front row and recorded every lecture. I don't really go back and listen to them, but they are useful if you forgot details about an assignment or if you wanted to double check the due date on an assignment being changed. Though, to me, the main reason was data. I wanted data... and I wanted as much as possible. When I teach, I also record everything. No matter the perspective, online classes make this much much easier.

So, what did I do? My usual. Made a completely overkill setup to preserve as much data as possible and accomplish the ultimate Zoom lecture recording. Speaking dramatically aside... Before I get to discussing the details on the setup, let's talk about Zoom and some technical details about it. This'll be important for later on.

On Black Friday last year, I got a pretty nice deal on an ultrawide HDR10 supported monitor by LG... so I bought two of them. One for my office at work, and one for home. It's definitely not a monitor used for mastering content, but it's a nice way to get into the world of HDR content creation. So, what can we do?

Well, as it turns out, there isn't a real way to record HDR at the moment via software (EDIT: Ok, maybe "Action!" can do it. I'll test that later). Content creators out there resort to using high quality capture cards to capture HDR10 gameplay. But why is there no software solution? Well, there is... sorta. But you have to get creative with it and manually do everything. For me, this is fine. I prefer being in full control in post. Let's experiment.

So recently I bought a game on Steam called Puyo Puyo Tetris. It's a crossover between... well... Puyo Puyo and Tetris! I've had a few good matches here and there with some friends and the game lets you save good matches as replays. With replays, you can go and rewatch gameplay at a later time. You can also slow down or speed up the gameplay as you wish when playing them back.

Okay that's a pretty useful feature right? Well it is useful until you hit the absurd 50 replay limit. For a PC port, I would've expected something like in Quake or Half-Life where the replays are stored in a separate file (and in an unlimited quantity), but unfortunately that isn't the case here. Nope, we're stuck with 50.

I have been a TA at University for around 3 years. From the very beginning, I made a website that serves as a 24/7 resource for students in courses I TA for. It contains lab hints, grading guides, files of code, etc that I write whenever I teach lab sections or host office hours.

However, the layout of the page has dated quite a bit since I first wrote it. Maybe it's time to give it a refresh? Sure! Why not!?

Introducing PENDUAL (In the event that this name choice isn't obvious...), a dual-theme setup consisting of a Light and (finally) a Dark theme! This isn't all I've changed though...

Almost yearly in the winter, me, my brother, and my Dad play a series of Half-Life games, which ends up being recorded and uploaded to YouTube. We call the series the "Christmas Deathmatch".

To me, I'm always up for a good game, but I'm also always up for a good media project. Christmas Deathmatch isn't popular by any means, but it is a good way to practice video editing and producing to me. So I'm going to show some behind-the-scenes stuff that went on with editing 2017's Christmas Deathmatch.

In the past years, I was very reliant on Adobe After Effects to do my work for me. As I went through 2016 and 2017, I realised there was a much more efficient and automated way to do the editing I needed without professional video editing software. I only used Adobe After Effects for parts of the video that I actually had to edit. The rest, I managed to actually automate. All rendering to x264 was automated into a few shell scripts and ffmpeg. It's going to sound complicated when you read this, but in the end, it's just simply setting up files so that the scripts can encode everything automatically.

So I'm willing to bet that a lot of Linux power-users out there use terminal multiplexers to increase their productivity.

The terminal, at first, can be quite intimidating. I like to expose my students to it whenever I am teaching them how to program in C or C++. This is because UTK Computer Science major students are forced to use it to do their lab assignments eventually (usually in their second year).

The terminal, put quite simply, is just a single session for a user to input commands. However, there are so many ways to change this that it is ridiculous. Let's look at a general terminal running zsh:

Note: This is actually a pretty outdated post now. YouTube has updated their video processing and audio support tramendously. Not only do they support higher quality audio, but they also support 5.1 surround sound! I'll keep the original post here for archival's sake. Do I support downloading from YouTube? No. But I'm not going to hide the fact they've improved in the past three years.

tl;dr - It's a terrible idea.

A frequent question I see on YouTube music videos is "How can I download this song?". A common answer to that question is to use a "YouTube to MP3" converter which will take the video and extract its audio stream (AAC), convert it to MP3, and then let you download it. Yes, you get the song, but let's be honest... The quality of that file is pretty shitty.
