Dead USB Drives Are Fine: Building a Reliable Sneakernet

from The Changelog [alt+shift+b] in programming

“OK,” you’re probably thinking. “John, you talk a lot about things like Gopher and personal radios, and now you want to talk about building a reliable network out of… USB drives?” Well, yes. In fact, I’ve already done it. What is sneakernet? Normally, “sneakernet” is a sort of tongue-in-cheek reference to using disconnected storage to … Continue reading Dead USB Drives Are Fine: Building a Reliable Sneakernet →

Celebrating 45 Years of Kermit with the First New C-Kermit Release in 15 Years (and working with a decades-old C codebase)

1981 was a different time for computing. It was expensive (both hardware and software), and it was far from a given that machines from one vendor would be able to talk to those from another. In fact, Columbia University had just such a problem, so in 1981, Frank da Cruz and Bill Catchings designed a … Continue reading Celebrating 45 Years of Kermit with the First New C-Kermit Release in 15 Years (and working with a decades-old C codebase) →

Artificial Intelligence: Shades of Gray

AI sure is a hot topic right now, and I see a lot of people arguing about it. To a lot of people around here, I’m the “computer person” they know and I get asked a lot about AI. I’m going to suggest a lot of things can be true at once. For instance: LLMs … Continue reading Artificial Intelligence: Shades of Gray →

Screen Power Saving in the Linux Console

I just made up a Debian trixie setup that has no need for a GUI. In fact, I rarely use the text console either. However, because the machine is dual boot and also serves another purpose, it’s connected to my main monitor and KVM switch. The monitor has three inputs, and when whatever display it’s … Continue reading Screen Power Saving in the Linux Console →

A Twisty Maze of Ill-Behaved Bots

Like many, bot traffic has been causing significant issues for my hosted server recently. I’ve been noticing a dramatic increase in bots that do not respect robots.txt, especially the crawl-delay I have set there. Not only that, but many of them are sending user-agent strings that are quite precisely matching what desktop browsers send. That … Continue reading A Twisty Maze of Ill-Behaved Bots →

Dreams of Late Summer

Here on a summer night in the grass and lilac smell Drunk on the crickets and the starry sky, Oh what fine stories we could tell With this moonlight to tell them by. A summer night, and you, and paradise, So lovely and so filled with grace, Above your head, the universe has hung its … Continue reading Dreams of Late Summer →

Community

I’ve been taking a break from Mastodon as my social home on the web for about six weeks. It has been more difficult than I’d usually admit. I have an amazing local community in my town that I love and am deeply involved in. But nobody here is a programmer, or even a computer nerd, so it doesn’t serve my need for a tech community. I work alone, for myself, in my house. It’s a fortunate lifestyle with many upsides, but it means I don’t get that form of community at work, either. I’ve had this feeling before… as a teenager in the 1990s. It’s profoundly lonely. But when I got internet access, that started to change. I found my people. First in the Total Annihilation community (RIP, Annihilated), then the HardOCP Forum, then the Something Awful Forums, then Tumblr, then Twitter and our community of Apple bloggers, and then Mastodon. Communities form, change, and dissolve over time. None of those are, today, anything like what they were when I most enjoyed them. We change, too. I didn’t move on from most of those solely because they changed — it was usually because we both changed, and it was no longer a good fit. My break from Mastodon has been a relief in some ways, as I’ve felt increasing divergence between what I wanted and what I was getting from it, but I didn’t know where else to go. Instagram, TikTok, and YouTube are all more video-broadcast platforms than communities. All I’ve found on Bluesky is even more anger and politics, the last things I need or want. Threads hasn’t yet stuck for me, and it’s owned by an asshole. Twitter was an amazing product and community that was previously owned by assholes, and now it’s X, which has a strong but different tech community, and is owned by different assholes. So I’ve just been… nowhere, for the first time since the 1990s. It has been, once again, quite lonely. Sure, it’s been relaxing, too, but in the way a vacation is relaxing. It’s great to take breaks, but after a long vacation, I’m ready to turn my brain back on. Without participating in a large, broad tech community, I’m exposed to fewer new ideas, both of my main jobs (app development and podcasting) are much harder, the quality and reach of my work have suffered, my skills aren’t improving as much, my mind is less stimulated, and I feel disconnected from my professions and passions. My world has gotten smaller. I could keep going like this to prove a stubborn victory or purity test, but I’d mostly just be hurting myself. Communities change, conditions change, and we change. We’re all better off if we’re willing to change our minds, and if our communities let us, no matter how strongly our younger selves declared a previous position. So I’m going to wade back in and see how it goes, trying to find a better balance to hopefully have better results, including on Mastodon. My people are spread across multiple services, and I’m going to explore them all, despite most of them being owned by assholes. I’d love to participate in communities without any assholes benefiting from it, but in the modern world, that simply isn’t possible. The only alternative is to isolate myself and not have a community at all (or a job, or a smartphone, or a computer, or internet access, or a car, or most of my food, or my country). That’s neither a price I’m willing to pay nor a condition I’d try to impose on anyone else. I’d love to have your support, forgiveness, and grace as I try to find my people again, and I strive to offer the same to all of you. Everyone deserves to be part of a community. And as I grow, I’m learning to declare fewer absolutes in a complex, imperfect, and constantly changing world.
