In Which I Vibe-Code A Personal Library System

December 3, 2025 by 48 Comments

When I was a kid, I was interested in a number of professions that are now either outdated, or have changed completely. One of those dreams involved checking out books and things to patrons, and it was focused primarily on pulling out the little card and adding a date-due stamp.

Of course, if you’ve been to a library in the last 20 years, you know that most of them don’t work that way anymore. Either the librarian scans special barcodes, or you check materials out yourself simply by placing them just so, one at a time. Either way, you end up with a printed receipt with all the materials listed, or an email. I ask you, what’s the fun in that? At least with the old way, you’d usually get a bookmark for each book by way of the due date card.

As I got older and spent the better part of two decades in a job that I didn’t exactly vibe with, I seriously considered becoming a programmer. I took Java, Android, and UNIX classes at the local junior college, met my now-husband, and eventually decided I didn’t have the guts to actually solve problems with computers. And, unlike my husband, I have very little imagination when it comes to making them do things.

Fast forward to last weekend, the one before Thanksgiving here in the US. I had tossed around the idea of making a personal library system just for funsies a day or so before, and I brought it up again. My husband was like, do you want to make it tonight using ChatGPT? And I was like, sure — not knowing what I was getting into except for the driver’s seat, excited for the destination.

Give Us One Manual For Normies, Another For Hackers

December 2, 2025 by 56 Comments

We’ve all been there. You’ve found a beautiful piece of older hardware at the thrift store, and bought it for a song. You rush it home, eager to tinker, but you soon find it’s just not working. You open it up to attempt a repair, but you could really use some information on what you’re looking at and how to enter service mode. Only… a Google search turns up nothing but dodgy websites offering blurry PDFs for entirely the wrong model, and you’re out of luck.

These days, when you buy an appliance, the best documentation you can expect is a Quick Start guide and a warranty card you’ll never use. Manufacturers simply don’t want to give you real information, because they think the average consumer will get scared and confused. I think they can do better. I’m demanding a new two-tier documentation system—the basics for the normies, and real manuals for the tech heads out there.

Chinese Regulators May Kill Retractable Car Door Handles That Never Should Have Existed

November 26, 2025 by 153 Comments

Headlights. Indicators. Trunk releases. Seatbelts. Airbags. Just about any part of a car you can think of is governed by a long and complicated government regulation. It’s all about safety, ensuring that the car-buying public can trust that their vehicles won’t unduly injure or maim them in regular operation, or in the event of accident.

However, one part of the modern automobile has largely escaped regulation—namely, the humble door handle. Automakers have been free to innovate with new and wacky designs, with Tesla in particular making waves with its electronic door handles. However, after a series of deadly incidents where doors wouldn’t open, regulators are now examining if these door handles are suitable for road-going automobiles. As always, regulations are written in blood, but it raises the question—was not the danger of these complicated electronic door handles easy to foresee?

Mating Cycles: Engineering Connectors To Last

November 20, 2025 by 56 Comments

If you take a look around you, chances are pretty good that within a few seconds, your eyes will fall on some kind of electrical connector. In this day and age, it’s as likely as not to be a USB connector, given their ubiquity as the charger of choice for everything from phones to flashlights. But there are plenty of other connectors, from mains outlets in the wall to Ethernet connectors, and if you’re anything like us, you’ve got a bench full of DuPonts, banana plugs, BNCs, SMAs, and all the rest of the alphabet soup of connectors.

Given their propensity for failure and their general reputation as a necessary evil in electrical designs, it may seem controversial to say that all connectors are engineered to last. But it’s true; they’re engineered to last, but only for as long as necessary. Some are built for only a few cycles of mating, while others are built for the long haul. Either way, connectors are a great case study in engineering compromise, one that loops physics, chemistry, and materials science into the process.

Tech In Plain Sight: Pneumatic Tubes

November 17, 2025 by 44 Comments

Today, if you can find a pneumatic tube system at all, it is likely at a bank drive-through. A conversation in the Hackaday bunker revealed something a bit surprising. Apparently, in some parts of the United States, these have totally disappeared. In other areas, they are not as prevalent as they once were, but are still hanging in there. If you haven’t seen one, the idea is simple: you put things like money or documents into a capsule, put the capsule in a tube, and push a button. Compressed air shoots the capsule to the other end of the tube, where someone can reverse the process to send you something back.

These used to be a common sight in large offices and department stores that needed to send original documents around, and you still see them in some other odd places, like hospitals or pharmacy drive-throughs, where they may move drugs or lab samples, as well as documents. In Munich, for example, a hospital has a system with 200 stations and 1,300 capsules,  also known as carriers. Another medical center in Rotterdam moves 400 carriers an hour through a 16-kilometer network of tubes. However, most systems are much smaller, but they still work on the same principle.

Moving From Windows To FreeBSD As The Linux Chaos Alternative

November 11, 2025 by 118 Comments

Back in the innocent days of Windows 98 SE, I nearly switched to Linux on account of how satisfied I was with my Windows experience. This started with the Year of the Linux Desktop in 1999 that started with me purchasing a boxed copy of SuSE Linux and ended with me switching to Windows 2000. After this I continued tinkering with non-Windows OSes including QNX, BeOS, various BSDs, as well as Linux distributions that promised a ‘Windows-like’ desktop experience, such as Lindows.

Now that Windows 2000’s proud legacy has seen itself reduced to a rusting wreck resting on cinderblocks on Microsoft’s dying front lawn, the quiet discomfort that many Windows users have felt since Windows 7 was forcefully End-Of-Life-d has only increased. With it comes the uncomfortable notion that Windows as a viable desktop OS may be nearing its demise. Yet where to from here?

Although the recommendations from the peanut gallery seem to coalesce around Linux or Apple’s MacOS (formerly OS X), there are a few dissenting voices extolling the virtues of FreeBSD over both. There are definitely compelling reasons to pick FreeBSD over Linux, in addition to it being effectively MacOS’s cousin. Best of all is not having to deal with the Chaos Vortex that spawns whenever you dare to utter the question of ‘which Linux distro?’. Within the world of FreeBSD there is just FreeBSD, which makes for a remarkably coherent experience.

“AI, Make Me A Degree Certificate”

November 10, 2025 by 139 Comments

One of the fun things about writing for Hackaday is that it takes you to the places where our community hang out. I was in a hackerspace in a university town the other evening, busily chasing my end of month deadline as no doubt were my colleagues at the time too. In there were a couple of others, a member who’s an electronic engineering student at one of the local universities, and one of their friends from the same course. They were working on the hardware side of a group project, a web-connected device which with a team of several other students, and they were creating from sensor to server to screen.

I have a lot of respect for my friend’s engineering abilities, I won’t name them but they’ve done a bunch of really accomplished projects, and some of them have even been featured here by my colleagues. They are already a very competent engineer indeed, and when in time they receive the bit of paper to prove it, they will go far. The other student was immediately apparent as being cut from the same cloth, as people say in hackerspaces, “one of us”.

They were making great progress with the hardware and low-level software while they were there, but I was saddened at their lament over their colleagues. In particular it seemed they had a real problem with vibe coding: they estimated that only a small percentage of their classmates could code by hand as they did, and the result was a lot of impenetrable code that looked good, but often simply didn’t work.

I came away wondering not how AI could be used to generate such poor quality work, but how on earth this could be viewed as acceptable in a university.
