What could you write down about a juggling pattern? (1993)
- sp332 8y agoThe Juggler3D "screensaver" https://linux.die.net/man/6/juggler3d https://linux.die.net/man/6/juggler3d can also be run manually with a pattern, and it will attempt to show a stick figure juggling with that pattern.
- kurthr 8y agoI hadn't seen this in OpenGL... it's nice to see some good open source simulators. I do remember a much older (than 2009 or even 2002) version called Juggle that ran on HPUX, but it may have been written in pascal and it certainly didn't render the man.
- BenjiWiebe 8y agoAnd my brother uses Juggling Lab to look at the simulations.
- sevensor 8y agoI first saw this through xscreensaver and was very impressed. At least as it's packaged for Arch, xscreensaver brings in loads of weird, fun, mind-expanding screensavers. It's always a surprise. I'm not sure if other distributions' packages pull in the full set of screensavers by default, but I imagine you can find them regardless.

- stephengillie 8y agoTaught myself to juggle grocery store bags while working at a grocery store. It's a little like spinning plates. You hang a bag in the air, leave it for a bit, and grab it before it hits the ground. Now interleave 3 of these: Start: - Hang bag A with right hand. - Hang bag B with left hand. - Hang bag C with right hand and grab bag A with left hand. Process: - Hang bag A with left hand and grab bag B with right hand. - Hang bag B with right hand and grab bag C with left hand. - Hang bag C with left hand and grab bag A with right hand. - Hang bag A with right hand and grab bag B with left hand. - Hang bag B with left hand and grab bag C with right hand. - Hang bag C with right hand and grab bag A with left hand. End: - Grab bag B with right hand. - Grab bag C with left hand, while still holding bag A. OR - Allow all bags to fall on floor, then collect them.
- kurthr 8y agoHey, maybe we'll get one of the originators on here? One interesting thing that happened when jugglers discovered siteswap was a proliferation in new patterns as they discovered the full space of (hand position independent) patterns. Some are more difficult to time/think than they are to throw/catch. For more history see the wiki... https://en.wikipedia.org/wiki/Siteswap https://en.wikipedia.org/wiki/Siteswap

- krallja 8y agoI like the finite state machine (directed graph) near the end. That means there’s a regular expression that can encode it.
- allenknutson 8y agoYou might like some of the papers about random traversals of this graph, e.g. http://front.math.ucdavis.edu/0302.5257 http://front.math.ucdavis.edu/0302.5257 and http://front.math.ucdavis.edu/1601.06391 http://front.math.ucdavis.edu/1601.06391
- allenknutson 8y agoFAQ writer here. I've got a video with demos https://www.youtube.com/watch?v=38rf9FLhl-8&t=105s https://www.youtube.com/watch?v=38rf9FLhl-8&t=105s from a few years ago. AMA.
- allenknutson 8y agoBTW I'm fairly sure I wrote the siteswap -> on-screen simulation, in 1988. In Pascal. A few years later three of us wrote http://www.juggling.org/programs/java/MAGNUS/juggler.html http://www.juggling.org/programs/java/MAGNUS/juggler.html in now-ancient Java, which did a ton more stuff.
- oceanghost 8y agoIs there an intersection between HNers and jugglers? I've been teaching myself contact juggling for... quite some time. I picked it because it was so far out of my comfort zone.
- jkh1 8y agoProbably. When I lived in the bay area, I juggled at the San Francisco circus center: http://circuscenter.org/juggling http://circuscenter.org/juggling and there's also a juggling club in Berkeley: https://berkeleyjuggling.org/ https://berkeleyjuggling.org/ Many jugglers I've met there worked in IT/software-related jobs.
- ashelmire 8y agoThere’s at least a few developers that juggle. I’m one.
- jmmease 8y agoI spent hours a day juggling for ~4 years in my mid teens (in my 30s now) and got up to juggling 8 balls. I find numbers juggling (say 5 or more) to be almost therapeutic. It requires a reasonable amount of physical exertion, and it just pulls you into a flow state. All of your mental and physical focus is concentrated on maintaining this ephemeral pattern, and there's no room for anything else... until the pattern falls apart :-)
- jamesrom 8y agoDo any online tools to validate and visualise siteswap notation exist?
- jkh1 8y agoYou just need your head :) Check http://www.siteswap.org/validate.html http://www.siteswap.org/validate.html Otherwise, check the software section here: http://www.siteswap.org/ http://www.siteswap.org/
- cryptolime 8y agoHi wrote this article in a blog explaining the basics if you are interested http://www.mathisintheair.com/eng/2018/02/21/maths-and-juggling/ http://www.mathisintheair.com/eng/2018/02/21/maths-and-juggl...
- dimovich 8y agoThanks! That was very informative.
- dtheodor 8y agoThis website is unchanged from 1993 (the web archive first crawled it in 1997), yet it looks great in my 4K screen. I wouldn't be able to tell if it was written yesterday or 20 years ago. Completely unlike the experience you are getting from something like this http://web.archive.org/web/19961112181513/http://www.nytimes.com:80/ http://web.archive.org/web/19961112181513/http://www.nytimes...
- wodenokoto 8y agoIt doesn't look great on my screen and I need to turn on reader-mode (which breaks the graphs) or zoom and scroll horizontally in order to read the content
- drngdds 8y agoMight be fine on a desktop but the ASCII art is illegibly small on my phone screen.
