I'm so glad the audio and video tracks are stored interleaved, as it made my solution possible, and the results I got were great. By splitting the interleaved video into small enough chunks, padding the audio, and cutting it exactly to video length, the padding was practically imperceptible.

The only issue I ran into was that ffmpeg can't cut audio with any real precision. I eventually figured out that I could dump the audio track to a headerless PCM file, calculate the exact byte offsets for my cut points, and cut them with perfect precision using the head and tail commands from GNU coreutils. This was perfect because I was able to use the cat command to combine all of the padded audio chunks into a single raw PCM file, which I then made an AAC encode of with ffmpeg to mux with my original encoded video track.

Fortunately, dvgrab does allow you to take the original .dv file and generate a .srt subtitle track with time stamps that you can mux into your encoded files.

The biggest issue I ran into was that while the audio and video were properly synced up in the original .dv file (due to it being an interleaved format), when I re-encoded the videos, the audio and video would drift out of sync as the video went on.

I was able to fix the sync issues by using dvgrab to split the original dv file into a bunch of 3 minute chunks. I then wrote a script to extract the audio track from each chunk, pad the end of the audio with milliseconds of silence to the exact length of the video track, combine the padded audio tracks, encodes the combined track, and muxes the fixed audio track with the encoded video. This worked really well; the silence padding is imperceptible, but the audio and video are still in sync - even after 2 hours.

A final point that needs making is that doing anything with dv files in ffmpeg (even -c:v copy) destroys the SMPTE timecodes embedded in the original file, making it much harder to split by scene.

The weather forecasts seem to have similar accuracy to the forecasts delivered by Google, but unlike Google's forecasts, if the first forecast generated by WeatherZOID is wrong the first time, you can get an accurate forecast by pressing the "Get Weather" button an indefinite number of times.

Edit: Happy April Fools day.

In additon, compared to PF/OPNsense or OpenWRT (Linux based), you have more control and exposure to the underlying network concepts with VyOS. You're not configuring the kernel manually, but you still learn quite a bit.

In a lot of modern cars, there's no straightforward way of fully disabling ABS, traction control, electronic stability control, etc. There are certainly situations where they may be helpful, such as in a top-heavy truck with an open differential, but ABS and traction control systems can pose problems in other situations, such as in snow. Especially in the case of RWD coupes with limited-slip differentials, a bit of skidding may be an asset, provided the driver knows how to correct for oversteer. Even in FWD cars, ABS can sometimes be a detriment when stopping in snow, as the rapid automated brake-pumping can dislodge the snow you were otherwise going to be holding steady on.

Ultimately, I'm opposed to driver assist features being forced onto drivers who don't want to use them. I'm also opposed to teaching people how to drive with these assistance features. It's a lot like teaching students to use AI chatbots to do their work instead of teaching them to do their work themselves.

We need to move back to putting users back into full control. Machines (including computers) should ALWAYS respect the input of the user, even if the user is wrong.

If a person shoots themself with a gun as a result of their incompetence, we don't fault the gun manufacturer for not designing the gun to prevent auto-execution. If you can't operate a firearm safely, you shouldn't attempt to operate a firearm.

Similarly, if a person deliberately points their car a solid object and accelerates into it, the actions of the operator shouldn't be the car manufacturer's responsibility. We need to get rid of ESC, ABS, AEB, etc. These features have created a whole slew of drivers who speed headfirst into the back of stationary drivers and expect their car to stop itself. This works right up until a sensor fails and the operator flies through the windshield (usually people like this don't wear seat-belts). If you can't drive, you shouldn't be driving until you rectify your incompetence.

Similarly, phones and computers should respect user input. If a users wants root access to their personal device, they should be able to get root access. If a user runs "rm -rf --no-preserve-root /" as root, the device should oblige and delete everything, since that is what the operator instructed it to do. If you can't be trusted to use a computer, you shouldn't be using a computer until you rectify your incompetence.

The lack of accountability in modern society is disgusting, and it leads to much deeper societal problems when people refuse to better themselves and instead expect the world to shield them from their willful ignorance.

The lack of labeling enforcement is really a problem. Genuine amanita muscaria mushrooms are a lot more like alcohol than psilocybin in terms of effects, and if you didn't know better, you could easily take a few to relax at the end of a stressful day and end up freaking out instead.

The biggest issue with the Prius (at least for the years in my price range), is that the driving experience is liable to make one fall asleep at the wheel. They're the perfect cars for monks; if you're willing to forego all earthly driving pleasures, you can get high 40s mpg.

My grandmother drove a Prius, and there was a stir in my extended family as to whether she should still be driving, as she'd been seen going 20mph below the speed limit and was driving pretty far to the right side of her lane.

I got the opportunity to drive her Prius and promptly found myself alternating between going too fast and going too slow. Between the awkward pitch of the windshield and the gross-feeling electric power steering, I wasn't the best driver either. I never have any of these problems in my 2005 Honda Civic LX or my family's 4-cylinder 2011 Ford Ranger. The Prius felt like one of those stoned driving simulators that police departments bring to high schools in an effort to prevent DUIs.

I like the idea of hybrids and EVs, but it's hard to justify completely losing the pleasure of driving for 10 extra mpg. For all I know, newer models may have improved this, but they're still to expensive for me to pay any real attention to.

I don't know how feasible this is, but it would be cool if there were open-source drop-in replacements for Google's server-sided APIs that app developers could use to replace Google's services with alternate servers running open source software.

Make sure to leave one star reviews on all such apps that you run into.

Prior to the PIRATE act of 2020, running a pirate FM station was effectively legal until the second time you were busted. Prior to 2020, if you shut the station down after getting your NOUO, there wasn't any real penalty. Teenage me loved this, and my buddies and I had a little irregularly-broadcasting pirate radio station, using a cheap CZH-7C transmitter purchased on eBay. One time we went on air from our high school's cafeteria during a study hall, and surprisingly, nobody questioned anything! We did have Microsoft Sam narrate our broadcast so that we weren't making a ton of noise.

We never did get our NOUO; instead, we ran into the much bigger reality, which was that none of us had anything of interest to say. After the novelty of hearing our voices on the radio wore off, the transmitter ended up in a closet, where it probably still sits today. Good times!
