    It can be, yes. One of the largest complaints with Docker is that you often end up running the same dependencies a dozen times, because each of your dozen containers uses them. But the trade-off is that you can run a dozen different versions of those dependencies, because each image shipped with the specific version they needed.

    Of course, the big issue with running a dozen different versions of dependencies is that it makes security a nightmare. You’re not just tracking exploits for the most recent version of what you have installed. Many images end up shipping with out-of-date dependencies, which can absolutely be a security risk under certain circumstances. In most cases the risk is mitigated by the fact that the services are isolated and don’t really interact with the rest of the computer. But it’s at least something to keep in mind.



  • Yeah, there’s also the “debugging is just as hard as writing elegant code” side of things. Vibe coding is largely just putting yourself in a permanent debugging role.

    The big issue I see with vibe coding is that you need to know best practices to build secure code. Even if you don’t adhere to them all the time, best practices exist for a reason. And a programmer who doesn’t even know them is a dangerous thing, because they won’t even be able to see what is insecure (until it’s far too late).

    Studies have found that vibe coders tend to produce less secure code, but have higher confidence in their code being secure; It’s essentially Dunning-Kruger in practice. I’d have no issue with someone using AI to get the broad strokes down. But then they need to be able to back it up with actual debugging. Not just “I didn’t even bother looking at it. If it compiles, push it to prod.”


  • If you already have a Plex instance running, Prologue is an app that turns it into an audiobook host as well. Plex doesn’t natively support audiobook metadata like chapters, but Prologue simply uses Plex’s remote access to reach the files.

    All you do is throw the .m4b audiobook files into a music library on Plex, sign into your Plex account on Prologue, and Prologue handles all of the metadata for the audiobooks instead of using Plex’s built-in music player.

    I mention this because I had massive issues trying to get ABS to work on my setup. It simply refused to read or write any data from my NAS. After a day or two of throwing myself at it to no avail, I found Prologue and haven’t looked back. I already had Plex running for some friends and family, so setting up the music library was as easy as dropping the audiobooks into a folder.



  • Yeah, the best way to learn a new game is by doing it. Video games have stopped burying tutorials in booklets, because they realized players didn’t actually read anything. Instead, they use the game itself to teach you how to play, by presenting the relevant information as it becomes relevant.

    You don’t need to read rules about a mechanic that starts 3/4 of the way through the game until you’re at the 3/4 mark. In video games, that usually manifests as a “congrats, you got a new ability. Here’s a quick three or four sentences on how it works” pop up. If that info is presented up front (like in a board game rulebook) then you’ll have forgotten how it works by the time it is relevant.



  • There’s also the Great Circle flight paths. Essentially, because the earth is round, it’s actually a shorter distance to fly in an “arc” (when looking at a flat map). In the below picture, the upper curved line is actually shorter than the lower straight line:

    Here’s another image which demonstrates why the curved line looks longer on a flat map:

    And because of how map projections work, this applies to virtually any flight path that isn’t directly north/south… Just like the one in OP’s photo.








  • They have port forwarding, but they were bought by a company that has been caught stuffing malware into purchased programs. Basically, it was a company that has a history of buying out otherwise legitimate software brands, and then bulking them with adware as a quick cash grab on the existing customers.

    That buyout was like 4 or 5 years ago, but it left a sour taste in many people’s mouths. Because everyone expected the PIA client to silently get bulked with adware one day. Since trust is basically the only reason to casually use a VPN, it pushed a lot of their users to alternatives.




  • I run both Plex and Jellyfin. Jellyfin is ready for everyone who doesn’t have to deal with the Mother-in-Law Factor. Plex has an easy setup process, and I could walk my MIL through it on my phone. In 5 minutes, her TV was connected to my server.

    Jellyfin isn’t to that point yet, and likely never will be. Since there’s no centralized server for an app to phone home to, there’s no way to create a unified account creation/login experience. Jellyfin is nice as a “just for me” server. But as soon as I have to help others use it, it becomes a nightmare. Walking my MIL through setting up Jellyfin on her TV was the reason I re-installed Plex in the first place.

    I had finally converted my wife away from using paid streaming apps, and dealt with all of the “Why do I have to use three different apps to access it on my three different devices? They all look different and are harder to use” complaints. By the time it got around to my MIL, I was tired of dealing with it and just reinstalled Plex so people could have a consistent experience.

    I still use Jellyfin for my personal viewing because I prefer it. But saying “just ditch Plex, Jellyfin is ready now” is a little disingenuous. Jellyfin is ready for the people who want to use it. But if you’re trying to convince people to ditch their streaming apps, you’re fighting a lot of social inertia. You need to be able to provide a consistent experience across their different devices, with a decent login experience. And Jellyfin definitely isn’t there yet.



  • just not so easy to setup or comparability for my shared users.

    Yeah, the biggest reason I use Plex is because of the wife/mother-in-law factor. Basically, how easy is it to get the people around you to use it? If it’s more difficult to use than Netflix or Hulu, many will immediately throw up their hands in learned helplessness, claim it’s too confusing, and refuse to try any more. Plex is the only self-hosting option that actually provides an elegant user setup experience. With Plex, adding a new user is as simple as having them make an account and then sending them the server invite.
