09:30:20 From Kevin Appert, Program Chair : welcome to the February SVFIG 09:31:56 From M Edward Borasky (@znmeb) : Yo! 09:37:28 From Samuel A. Falvo II : Oh, I've seen this before! 09:38:48 From Samuel A. Falvo II : (Q for later if I don't get the chance) What makes this problem hard? Is it the speed of the vehicle/robot? Or measurement latency from sensors? ...? 09:47:35 From Juergen Pintaske : Great presentation - thank you Duncan 09:49:17 From Samuel A. Falvo II : I reckon one must consider also the intermittent flashes from cameras too. 09:51:20 From Juergen Pintaske : Hi David Henderson 09:54:43 From Kevin Appert, Program Chair : Big software affects the weight of the processor needed to run it. 09:58:44 From Kevin Appert, Program Chair : pessimizing compiler 10:02:33 From Samuel A. Falvo II : Reminds me of Moore's OKAD work, where he chose units specifically to optimize multiplications and divisions into bit-shift operations. 10:07:41 From Samuel A. Falvo II : It's all good! This is a very interesting topic. 10:11:06 From Juergen Pintaske : Is there a simulated version, where you can "run" a mouse without having one? 10:12:39 From Samuel A. Falvo II : This reminds me a lot of the Karel the Robot teaching aid. https://en.wikipedia.org/wiki/Karel_(programming_language) Only this is "real world" aware. 10:16:43 From Samuel A. Falvo II : Ooooohhhh.... clever!! 10:31:28 From Kevin Appert, Program Chair : anybody remember the GAPP processor? 10:37:46 From Duncan : Useful links: http://www.swallow.co.uk/light-sensors.pdf https://ukmars.org/ https://www.youtube.com/watch?v=ZMQbHMgK2rw https://github.com/micromouseonline/mazefiles/tree/master/classic 10:39:08 From Don Golding : excellent talk! Would love to hear about algorithms. 10:39:16 From Samuel A. Falvo II : Seconded 10:43:00 From Kevin Appert, Program Chair : I'll ask if he'd like to publish his code, but he nixed more talks 10:46:23 From Kevin Appert, Program Chair : Thanks for the links, Duncan! 10:51:41 From Travis Bemann : I recommend a heapsort 10:51:49 From Samuel A. Falvo II : Excel probably is using Quick Sort. 10:52:08 From Travis Bemann : heapsort provides decent performance while not requiring recursion 10:52:46 From Travis Bemann : the problem with quicksort is that it requires recursion, which is problematic if your stack space is limited but you have large quantities of data to sort 10:52:47 From Samuel A. Falvo II : Sure, but Excel is likely using Quick Sort. 10:53:13 From Travis Bemann : note th at heapsort isn't a stable sort 10:53:40 From Travis Bemann : excel doesn't have to worry about stack space in practice 10:53:59 From iPhone : Radix sort used in biology chromosome dna etc 10:54:01 From Samuel A. Falvo II : Correct. Just providing an answer to Bill's question. 10:54:07 From Brad Nelson : Everybody seems to be using Timsort these days: https://en.wikipedia.org/wiki/Timsort#:~:text=Timsort%20is%20a%20stable%20sorting,only%20consecutive%20runs%20are%20merged. 10:54:33 From iPhone : Radix sort eliminates if statements 10:55:35 From iPhone : Do u have the YouTube’s links ? 10:56:31 From Samuel A. Falvo II : https://www.youtube.com/watch?v=FwV4kELI6Lw 10:58:36 From Ken Boak : @Kevin Appert, Program Chair - Kevin, I have had a change in employment circumstances, (for the better). If there is 2 minutes available at the end of the program, would it be possible for me to update the group with what I am currently doing? 10:59:16 From Don Golding : Reacted to "@Kevin Appert, Progr..." with ❤️ 11:03:39 From Bill Ragsdale : Video editor Pinnacle about $80 one time cost. 11:03:48 From onatto : can i demo something i made in my own forth? 11:04:38 From Kevin Appert, Program Chair : Can you wait until next month? IFF not, maybe after Brad. 11:05:10 From onatto : sure next months fine 11:05:22 From onatto : it was a video app coincidentally too 11:10:03 From iPhone : Links they also had screen storage Was there a link from screen to blocks ? Cannon cat had a forth editor 11:13:58 From Kevin Appert, Program Chair : Onatto, we'll tease it after Sam and Ken are done before Brad. Can you show in two minutes and talk next month? 11:20:07 From onatto : @Kevin yes i can show it quickly 11:20:28 From onatto : sorry just saw - i was making orange juice in the background:) 11:29:18 From Travis Bemann : we can see you 11:35:50 From Samuel A. Falvo II : @onatto I may not be at the next SVFIG meeting, but I would still *love* to see a detailed presentation on your Forth environment for Steam. This sounds really awesome! 11:37:25 From Kevin Appert, Program Chair : CyFy is the YouTuber home inspection guy I mentioned, utterly fascinating and terrifying. 11:45:57 From Don Golding : finishing up our Log Home build as owner/builder. We passed every inspection first time! I am amazed. We only have our final inspection left for Occupation Certificate. 1 1/2 year project. Should be done in May... 12:03:50 From Samuel A. Falvo II : The Steamer 16 architecture only supports 3 stack elements, and it has never failed me. (My S16X4 processor family extends it to 4 elements as well, but that's more for electronic symmetry than compulsory functionality.) 12:03:55 From Kevin Appert, Program Chair : There was a time where the programmer's calculator was my constant companion. Then for years the emulator occupied a window on my laptop or desktop machine. I'm still yearning for one for my phone. I guess Excel fills the void. 12:04:35 From Kevin Appert, Program Chair : *when not where 12:06:50 From Ken Boak : Replying to "The Steamer 16 archi..." 👍 12:07:08 From Samuel A. Falvo II : My significant other will be needing my help shortly. So, I'm going to head out. Many thanks to everyone! 12:07:22 From Don Golding : Reacted to "My significant other..." with 👍 Your talks are always a great part of a SVFIG meeting. I have no idea how you can be so productive. 12:07:42 From M Edward Borasky (@znmeb) : SwissMicros has updated versions of all the HP calculators. 12:08:10 From M Edward Borasky (@znmeb) : Bonus - Forth runs on some of the newer ones! 12:08:37 From onatto : hey sorry i've had a call 12:08:50 From onatto : catch you next month for some good stuff
