I had a "rocket" crystal radio like this in the 60s: http://www.esnarf.com/7395k.htm

Show HN: Five-couples-meet problem, visual guide to solution

Posted by jkleiser on Tuesday December 27, 2022 @03:52AM
from the show-hn dept.

http://5couples.surge.sh

I found this problem in Scientific American in the 70's, and it's been one of my favourites since then. It is possible to solve it without even using pen and paper (I believe I did back then), but I got the idea that some visual guidance could be helping to some. That's why I made this little single-file web "app". (You may add "?lang=no" to the URL to get Norwegian texts.) Have fun!

Great! Thanks a lot.
Re:Solidjs – JavaScript UI Library on Tuesday November 30, 2021 @04:30AM (#29390432)
When I go to https://markojs.com in Safari (14.1.2), the CPU load on my MacBook Air goes up above 100%. If I use the Brave browser, the CPU load is closer to 25%. Still too much.
Re:A History of Primary Colours (2020) on Tuesday January 19, 2021 @06:45AM (#25832488)
Interesting. I'm just wondering why the color green has not been discussed in more detail in this text.

AppRun (https://apprun.js.org) is a very nice JavaScript library for building reliable, high-performance web applications, including SPAs.

Great article! I have only done a few simple projects with React, except for one where we used Redux. For me, Redux is too much clutter. I can recommend a look at this article: https://medium.com/@yiyisun/redux-vs-the-react-context-api-v... I've been working on an AppRun based hobby project for a couple of months now, and I find state management there to be quite easy. No clutter!

If you have a Mac and want to play with Oberon Workstation, you can find it in the Mac App Store: https://itunes.apple.com/us/app/oberon-workstation/id1057155...
Re:Gallery of programming UIs on Tuesday March 20, 2018 @07:33AM (#16627592)
Impressive! However, no mention of Oberon or BlackBox; that's a serious omission. http://fruttenboel.verhoeven272.nl/Oberon/index.html, https://github.com/pdewacht/oberon-risc-emu, http://blackboxframework.org/index.php?cID=home,en-us

Thanks for the links!
Re:Oberon Workstation on the Mac App Store on Monday January 11, 2016 @02:33PM (#10882685)
What a great surprise! I look forward to re-learn this system and language. I'm glad Oberon isn't dead. I just discovered this http://oberon.vishap.am and this https://github.com/BlackBoxCenter/blackbox.

Very cool! However, the "zydeco" sample wasn't typical zydeco at all. I guess it was Wayne Toups, and I'm sure he can do some real groovy zydeco, but this wasn't. ;-)
Re:Show HN: WebGL-powered oscilloscope emulator on Friday September 04, 2015 @06:45AM (#10169655)
I like it, but I would prefer a plain oscilloscope function, and being able to connect it to a Web Audio source of mine.

If you really want to do some serious concatenative programming, this is probably a useful site: http://www.factorcode.org
Re:Oberon/F for Mac OS (1997) on Monday October 20, 2014 @04:15AM (#8481098)
If you have access to MS Windows, you can find the latest version here: http://www.oberon.ch/blackbox.html A very beautiful piece of software in my opinion (but not available for Mac OS X).

If your machine is running some Unix OS, then PicoLisp is what I would recommend. -> http://picolisp.com/
Re:React Components on Thursday September 04, 2014 @04:14AM (#8267208)
Very nice! I think it would be great if the clickable component names on the right could have some kind of tooltip that contained a brief description of the component. E.g.: For the react-messages it could be "React component for showing error, warning, info messages."
Re:JavaScript: The Right Way on Friday January 17, 2014 @06:30AM (#7075269)
I would have expected to find React (http://facebook.github.io/react/) among the frameworks.
Re:Behind the Scenes with Chicken Scheme on Friday May 03, 2013 @06:21AM (#5649584)
Unless you're stuck in Windows, I suggest you take a look at PicoLisp, a very rich and interesting development system. The Wiki is of course written in PicoLisp: http://picolisp.com/
