<p>You betcha, Aurornis.  Simple economics tells us that cheap work drives out quality.  (Is that Gresham's law?).<p>Slowly, people will adapt to AI in online forums.  But for me, it's one more reason to share coffee with friends, rather than investing hours in social media.</p>

<p>AI hallucinations are getting ambitious.<p>A couple people recently emailed, asking whether the Klein bottle business was still operating after my death.<p>“Huh?” I thought. “I ain’t dead yet.”<p>After some digging, I discovered the source: an AI-generated review of The Cuckoo’s Egg circulating on Facebook. Alongside the usual synthetic praise and fabricated details, it confidently announced that I had died in May 2024.<p>Apparently AI has now advanced to the point where it can kill people off before they notice.<p>Mark Twain once wrote, “Reports of my death are greatly exaggerated.” I never expected to field-test the quote personally.<p>source: https://www.facebook.com/story.php?story_fbid=989939243570691&id=100076638743004<p>Cheers,   -Cliff</p>

<p>Strongly agree: scribbling requirements, process maps, and block diagrams goes a long way to understanding what needs to be done, as well as getting us to think through what'll be the easy parts and pinch-points.<p>Goes back to Fred Brooks' Mythical Man-Month: Start with understanding the requirements; then design the architecture.  Only after that, begin programming.</p>

<p>Yes, Riffraff -- We did that film (yep, 16mm film) just a few months after I finished writing Cuckoo's Egg.  At the time, the world was ignorant of words like "Internet" "Unix" and "e-mail", so I had to define each of these as I went along.</p>

<p>Yep, I no longer make regular Klein bottles.  I'm a so-so glassblower.  (Indeed, most glass workers would consider me a good physicist.  Physicists would say that I'm a good computer jock.  Computer people think that I know a lot about math.  Mathematicians feel that I'm a good glassblower.<p>Keep 'em all guessing.</p>

<p>Thanks, Resistor-burner!<p><pre><code>   I have fun with every Klein bottle order.  When someone buys a Klein bottle, I celebrate by walking through our backyard garden, looking for new blossoms.  I usually take a few photos and send these to my customer-friend.

  This micro business puts me in touch with fascinating people (I've met kids in elementary school, grad students, Nobel laureates, even a delightful nut who made a 4-meter tall wooden Klein bottle for Burning Man).  The kind of people you find here on Hacker News.

  PS - with reference to your HN identity -- from my ham radio days of long ago, I once experimentally determined that a 1/2 watt, 600 ohm Ohmite resistor would burn up when inserted in a 120V outlet.  Hmmm: 24 watts into a half-watt resistor?  Yep, filled the room with that acrid smell...   Don't try this at home.</code></pre></p>

<p>Hi Matt,<p><pre><code>   All of a sudden, I got three or four Klein bottle orders.  That's a lot for an hour!  One of the orders (thank you Bryan in Johnstown) mentioned Hacker News.  And, well, here I am.</code></pre></p>

<p>Yep, I'm the same guy.  Almost 40 years ago, I chased down those German hackers in my unix boxes; not knowing a thing about writing, I wrote Cuckoo's Egg.  (a long story there - how to write a book)<p>Since then, I've lowered my periscope:  my wife, Pat, and I decided to stay home together and raise two kids. They're now fledged - hooray! During that time, I started this micro-business of making Klein bottles - much fun!<p>Alas, but this past December, my wife left this vale of toil and tears. During the day, staying busy helps keep the grief under control; other times I'm in deep sadness, trying to find my way without her.<p>To all my friends & acquaintances on HN: my deep thanks for your kindness & support across decades.  It's a joy to be considered a member of the tribe.</p>

<p>Terrific article by Nicolas Hatcher!  Aperiodic tilings are fun to make from paper, wood, and ceramics.  I've cut tiles from ceramic field tiles.<p>No surprise that concave cuts in ceramics are a high stress, so Kite and Dart tiles don't work very well (the dart is likely to crack).  Same is true for the Turtle, Hat, and Spectre.<p>Rhombus tiles are everywhere convex, and the P3 Rhombus tiles are easy to cut in a diamond saw (or even a snap-cutter).  With a diamond band-saw, it's possible to make Penrose rhombs with curved (parabolic) edges.<p>But cutting tiles from stock field tiles produces sharp surface edges -- you don't want these as bathroom floor tiles.  Also, you waste a lot of the field tile as scrap. To get "friendly" tile shoulders, I'm experimenting with making Penrose tiles directly from high-fired porcelain clay.</p>

<p>Is there any SVG extension which allows density of line?  I have a plotter which can lift/lower a pen; it's driven from SVG files.  It'd be sweet to allow the pen to lower while the line is being drawn (as we often do with handwriting).<p>Oh - it's an Axidraw, from Evil Mad Scientist Labs - great device, wonderful people.</p>
