Forgotten Internet: Giving (or Getting) The Finger

January 30, 2025 by Al Williams 27 Comments

Hey, you know that guy in accounting, Marco? If you want to find out more about him, you’d probably go surf LinkedIn or maybe a social media site. Inside a company, you might look on instant messaging for a profile and even find out if he is at his desk or away. But back in the 1970s, those weren’t options. But if Marco was on the computer system, maybe you could finger him. While that sounds strange to say today, Finger was a common service provided by computer services at the time. It was like a LinkedIn profile page for the 1970s.

Based on RFC 742, Finger was the brainchild for [Les Earnest]. From a user’s point of view, you put a few files in your home directory (usually .project and .plan; both hidden files), and when someone “fingered” you, they’d see some human-friendly output about your account like your name and office location, if you were logged in or not, and the contents of your project and plan files.

Modern versions may also show your public PGP key and other data. You could usually put a file in your home directory called .nofinger if you wanted to stop people from fingering you.

r/keebgirlies Is Totally a Thing Now

When [coral-bells] posted her first build to r/mechanicalkeyboards, she likely felt some trepidation. After all this is reddit we’re talking about, so right away you’ve got two layers of male-domination hobby.

What she likely didn’t expect was to be upvoted into the tens of thousands, or to receive such a response from other girlies who came out of the woodwork to share their builds.

And so r/keebgirlies was born, and already has a few thousand members. This is a brand-new subreddit for women and non-binary folks who are into mechanical keyboards. As it says in the sidebar, men are welcome but limited to the comments for now, so don’t go trying to post your builds. The girlies are currently seeking moderators, so give that some thought.

As for [coral-bells]’ lovely build, this is an Epomaker MS68 with MMD Vivian V2 switches, and those flowery keycaps are from Etsy. She is currently waiting for supplies to mod a Yunzii AL66, but wants to build a kit at some point.

The FTC Take Action, Is Time Finally Up For John Deere On Right To Repair?

January 27, 2025 by Jenny List 43 Comments

Over the last decade we have brought you frequent reports not from the coolest of hackerspaces or the most bleeding edge of engineering in California or China, but from the rolling prairies of the American Midwest. Those endless fields of cropland waving in the breeze have been the theatre for an unlikely battle over right to repair, the result of which should affect us all. The case of FEDERAL TRADE COMMISSION, STATE OF ILLINOIS, and STATE OF MINNESOTA, v. DEERE & COMPANY relates to the machinery manufacturer’s use of DRM to restrict the repair of its products, and holds the promise to end the practice once and for all.

This is being written in Europe, where were an average person asked to name a brand that says “America”, they might reach for the familiar; perhaps Disney, McDonalds, or Coca-Cola. These are the flag-bearers of American culture for outsiders, but it’s fair to say that none of them can claim to have built the country. The green and yellow Deere tractors on the other hand represent the current face of a company with nearly two hundred years of farming history, which by virtue of producing some of the first mass-produced plows, had perhaps the greatest individual role in shaping modern American agriculture and thus indirectly the country itself. To say that Deere is woven into the culture of rural America is something of an understatement, agricultural brands like Deere have an enviable customer base, the most loyal of any industry.

Thus while those green and yellow tractors are far from the only case of DRM protected repairability, they have become the symbolic poster child for the issue as a whole. It’s important to understand then how far-reaching it is beyond the concerns of us technology and open-source enthusiasts, and into something much more fundamental.

Hackaday Links: January 26, 2025

January 26, 2025 by Dan Maloney 7 Comments

Disappointing news this week for those longing for same-hour Amazon delivery as the retail giant tapped the brakes on its Prime Air drone deliveries. The pause is partially blamed on a December incident at the company’s Pendleton, Oregon test facility, where two MK30 delivery drones collided in midair during light rain conditions. A Bloomberg report states that the crash, which resulted in one of the drones catching fire on the ground, was due to a software error related to the weather. As a result, they decided to ground their entire fleet, which provides 60-minute delivery to test markets in Arizona and Texas, until a software update can be issued.

Networking History Lessons

January 25, 2025 by Elliot Williams 34 Comments

Do they teach networking history classes yet? Or is it still too soon?

I was reading [Al]’s first installment of the Forgotten Internet series, on UUCP. The short summary is that it was a system for sending files across computers that were connected, intermittently, by point-to-point phone lines. Each computer knew the phone numbers of a few others, but none of them had anything like a global routing map, and IP addresses were still in the future. Still, it enabled file transfer and even limited remote access across the globe. And while some files contained computer programs, others files contained more human messages, which makes UUCP also a precursor to e-mail.

What struck me is how intuitively many of this system’s natural conditions and limitations lead to the way we network today. From phone numbers came the need for IP addresses. And from the annoyance of having know how the computers were connected, and to use the bang notation to route a message from one computer to another through intermediaries, would come our modern routing protocols, simply because computer nerds like to automate hassles wherever possible.

But back to networking history. I guess I learned my networking on the mean streets, by running my own Linux system, and web servers, and mail servers. I knew enough networking to get by, but that mostly focused on the current-day application, and my beard is not quite grey enough to have been around for the UUCP era. So I’m only realizing now that knowing how the system evolved over time helps a lot in understanding why it is the way it is, and thus how it functions. I had a bit of a “eureka” moment reading about UUCP.

In physics or any other science, you learn not just the status quo in the field, but also how it developed over the centuries. It’s important to know something about the theory of the aether to know what special relativity was up against, for instance, or the various historical models of the atom, to see how they inform modern chemistry and physics. But these are old sciences with a lot of obsolete theories. Is computer science old enough that they teach networking history? They should!

Hackaday Podcast Episode 305: Caustic Clocks, Practice Bones, And Brick Layers

January 24, 2025 by Kristina Panos 2 Comments

This week, Hackaday’s Elliot Williams and Kristina Panos joined forces and Wonder-Twin rings to bring you the latest news, mystery sound, and of course, a big bunch of hacks from the previous week.

First up in the news: Big boo to Bambu Labs, who have tried to clarify their new authentication scheme and probably only dug themselves in deeper with their customers.

On What’s That Sound, Kristina didn’t get close at all, but at least had a guess this time. Do know what it is? Let us know, and if you’re right and your number comes up, you can keep warm in a limited edition Hackaday Podcast t-shirt.

Then it’s on to the hacks and such beginning with a rather nice reverse-engineering of the Yamaha PRS-E433 keyboard, which led to a slice of Bad Apple playing on the tiny screen.

After that, we take a look at an NES musical instrument, how to make wires explode with energy, and a really cool space mouse that uses flexures. Finally, we talk about a piece of forgotten Internet history, and a whole bunch of keyboards.

Check out the links below if you want to follow along, and as always, tell us what you think about this episode in the comments!
