09:00:35 From Bayona, C : Greetings from NW ARkansas. 09:02:14 From Don Golding : Brad, you got Demitri's presentation? I don't know if his audio would go through the Zoom audio. I did download it in case I need to play it. 09:03:27 From Juergen Pintaske : Greetings from Exeter UK 09:04:09 From Don Golding to Brad Nelson(Direct Message) : Brad, you got Demitri's presentation? I don't know if his audio would go through the Zoom audio. I did download it in case I need to play it. 09:04:39 From Brad Nelson to Don Golding(Direct Message) : I have got his presentation and can play or you can if you'd rather? Investigating the audio one sec... 09:10:14 From Don Golding to Brad Nelson(Direct Message) : You do it, if possible. You have more controls. 😁 09:16:33 From Brad Nelson to Don Golding(Direct Message) : k 09:34:49 From greg : 1 ?DLL" GDI32.dll" 2 6 1 UX" CreateDIBSection" u.CreateDibSection ( ofs hsec 3 ^^bits usage ^bminfo hdc - hbm) 09:35:27 From Brad Nelson : Great presentation Xuyang! 09:35:53 From Xuyang Chen : movForth compiler source: github.com/reschivon/movForth 09:36:08 From Don Golding : Xuyang fantastic! 09:36:10 From Peter Milford : Ting: your voice quality is very poor 09:36:26 From Xuyang Chen : Thanks Don 09:40:43 From Kevin Appert : I hope you'll present again in a month or two, Xuyang. 09:50:57 From greg : Ting, don't forget in about 2006-7 Bill Muench put an eForth virtual machine and system on the GA144. 09:51:42 From Dave Jaffe : Dave Jaffe = davejaffe@stanford.edu 09:52:52 From Chen-hanson Ting : chenhansunding@gmail.com 09:53:05 From Chen-hanson Ting : jeforth615html.zip https://drive.google.com/file/d/1rfd4eIZAB2N1X9pH_RYI1bcxQDV5q-it/view?usp=sharing 09:53:26 From Juergen Pintaske : Where can I find the GA144 version of eForth on the GA website or elsewhere? 09:55:08 From greg : Juergen, it has been available there for a good 12 years 09:55:23 From Xuyang Chen : It's tricky to make Forth object oriented because OO restricts how data can be used. The dictionary can hold any type of data but OO requires the data be defined beforehand. 09:55:29 From greg : polyFORTH is also available there 09:56:54 From greg : We use class-instance structures in all sorts of applications over here, Xuyang. What I have learned is that each application typically calls for a different structure, but fortunately it takes very little work to implement one. An hour or two at most. 10:09:29 From Xuyang Chen : Are you referring to objects written on top of Forth? I am taking about an interpreter written using object oriented techniques. 10:10:29 From John Masseria : Who hasn't had this problem? 10:14:24 From Atle Ramsli, Oslo, Norway : The simplicity of it is brilliant! 10:17:43 From Kevin Appert : we can call this "Physical Object-Oriented Code" 10:18:22 From Kevin Appert : extra hyphens available for a small charge 10:18:24 From Erik Olson : Is each signed distance function intended to be exact in the general case? (Eg shortest distance from point to complex surface) Or just good enough to detect point inside-outside? 10:21:56 From Erik Olson : I really like the idea of CSG in Forth. I like writing code to generate G-code, better than using CAD. Also, SCAD programming is how I like to interact with CSG. 10:24:13 From Brad Nelson : With signed distance field used to detect inside/outside, you don't actually need it to be the exact shortest distance. 10:26:11 From Brad Nelson : But, if you use SDF for things like penetrating some distance into the object, then it does matter if it's exact. For example if I wanted to use it for smoother outer surface it might matter (though depends on what technique is used). 10:39:04 From Dave Jaffe : The SVFIG Meeting Notes Index can be found at http://forth.org/svfig/kk/kk.html 10:40:27 From Dave Jaffe : SVFIG videos can be found at http://forth.org/svfig/videos/index.html 10:41:15 From Dave Jaffe : Thank Brad Nelson for recording and segmenting the Zoom video 10:41:52 From Bob Armstrong : 👍 10:42:21 From Dave Jaffe : The SVFIG YouTube channel can be found at https://www.youtube.com/channel/UC2v6b9814uIA5egk5-yHAVw 10:48:25 From Kevin Appert : or at https://www.youtube.com/c/SiliconValleyForthInterestGroup 10:59:04 From Erik Olson : This reminds me of Open Firmware. 11:00:08 From Dave Jaffe : Moore is yet to come - Chuck's Fireside Chat is scheduled for 12:30pm PST 11:01:59 From Kevin Appert : you ready to go, Don? 11:25:34 From Christopher Lozinski : I will take one with 8 please. 11:26:21 From vido : Never ask "Who would need that ?"😉 11:29:52 From vido : Have you considered using the GA chip ? 11:30:14 From Kevin Appert to Brad Nelson(Direct Message) : Who is showing Demitri's PowerPoint? 11:38:45 From Christopher Lozinski : Don, the previous speaker, what is your email address? 11:38:59 From Erik Olson : What are those development boards ? Lattice, Creative RISC-V, igloo2? Are they available products? (I couldn’t find an Igloo2 for $20) 11:39:24 From Don Golding : DONALDRGOLDING@GMAIL.COM 11:40:01 From Don Golding : Lattice FPGAs are low cost. 11:40:25 From Christopher Lozinski : I can't hear it. 11:40:43 From Erik Olson : I have IceStick and BlackIce boards - I stockpiled ICE40HX1K at $4 11:40:51 From Don Golding : https://www.tindie.com/products/tinyvision_ai/upduino-v30-low-cost-lattice-ice40-fpga-board/ 11:41:18 From vido : Please speak closer to the microphone. 11:41:55 From Christopher Lozinski : I still can't hear it. The previous speaker was fine. 11:42:55 From Don Golding : Download Lattice Radian tools for free. https://www.latticesemi.com/Products/DesignSoftwareAndIP/FPGAandLDS/Radiant 11:42:58 From Dave Jaffe : Compiling Prolog to Forth - Lou Odette https://www.reddit.com/r/prolog/comments/5p1fsd/compiling_prolog_to_forth_lou_odette 11:44:02 From Don Golding : Yes, Demitri started with that paper. He went on to add new capabilities. 11:50:22 From Atle Ramsli, Oslo, Norway : I have to run! Hope to see the video when it becomes availabie. 12:21:46 From Bob Armstrong : The note from my presentation are under today's date at http://cosy.com/y21/Presentations.txt 12:33:46 From Kevin Appert : Welcome Elizabeth! 12:55:44 From vido : What about hexadecimal numbers ? 12:57:15 From vido : Wow, that is true minimalism. 13:02:42 From Bob Armstrong : One of the purchasers of APL+PC.CoSu was actuary Gary Venter whose brother Craig founded gentek and was the first person to sequence his ( own ) DNA . 13:03:51 From Dave Jaffe : Be Moore Like Chuck - http://sigusr2.net/be-moore-like-chuck.html 13:05:13 From Dave Jaffe : SIGUSR2 - https://sigusr2.myspreadshop.com 13:23:44 From Dave Jaffe : RayBan Stories https://www.ray-ban.com/usa/ray-ban-stories 13:24:36 From Dave Jaffe : $299 13:39:33 From Quinn Trejo : a "killer app" for smart glasses is a terminal and a secure keyboard connection, also an e-reader. A huge number of people wear glasses, but have little interest in creating video, don't forget about us! 13:47:24 From Erik Olson : “Proprietor and Chief Bottle Washer” is an idiom (I think in the movie Only Angels Have Wings) 13:48:38 From Dave Jaffe : In Memory of Our Friends and Colleagues - http://forth.org/svfig/memory.html 13:48:48 From Erik Olson : https://kguttag.com/ writes a lot about AR and VR glasses 13:48:59 From Erik Olson : (Another legendary CPU designer)
