**** BEGIN LOGGING AT Wed Mar 13 02:59:57 2019 Mar 13 16:36:28 gm all. Mar 13 16:36:35 sorry I am late. Mar 13 16:37:23 anyone here? Mar 13 16:37:34 I'm here. Mar 13 16:37:51 It has been pretty quiet. Mar 13 16:38:10 hi hendersa Mar 13 16:38:20 * hendersa waves. Mar 13 16:38:44 Hi and gm Mar 13 16:39:12 hi praked Mar 13 16:39:59 praked, looking to submit a proposal? Mar 13 16:40:59 Yes, I working on my proposal, had a chat with hendersa about the project idea last month. Mar 13 16:44:19 cool. what is the project? gaming related? Mar 13 16:46:14 * jkridner[m] wonders what a USB rubberduckie is. Mar 13 16:46:42 I believe it was the parallel bus example implementation that we were talking about. Mar 13 16:46:48 Gpio based Parallel bidirectional bus , maybe use pru's as well Mar 13 16:46:56 Hi everyone Mar 13 16:47:19 zeekhuge usually was answering questions in the early morning, and I'd answer questions in the afternoon for anyone asking. Mar 13 16:48:12 The parallel bus and USB configfs usually got a few questions. Mar 13 16:48:43 hendersa thanks very much to you and zeekhuge for being around Mar 13 16:49:18 Hello! I'm Sanuj from NSIT, Delhi, India and I need help for GSOC on project on "Low-Power Wide area networking" Mar 13 16:49:31 Can anyone say anything about the project idea PocketBeagle stepwise mathematics? Mar 13 16:50:16 For anyone requesting help, we ask that you have some specific questions that we can help you with. Mar 13 16:50:31 I shared my views on the project on Google Groups, and once on chat above but i don't know if I'm heading to right direction. I need mentors to help me along Mar 13 16:51:07 hendersa: I could find 299s and tried something with a hc4067 and a pi Mar 13 16:51:39 the more specific the questions, the better. Mar 13 16:52:23 Actually the gsoc idea page does not provide any link to the project. So I don't know what I actually need to do for the stepwise mathematics Mar 13 16:52:28 praked[m]: Does the time required to mux using the hc4067 make it practical for bus communication? Will it slow things down too much? Mar 13 16:53:08 "Preference Design For A GPIO-based Parallel Bi-Directional Bus" i am interested on this project to carry it forward . Mar 13 16:53:20 One of my query in project related to "Low-Power Wide area networking" is that Narrow-band IOT / Sigfox are proprietary. So how will be using it in our open-source development? Mar 13 16:53:38 praked[m]: How does it compare to using a shift register in terms of overhead (i.e. clock and control time to shift data in and out of the registers)? Mar 13 16:54:43 @iamshankhadeep: where does the idea come from and can it be added to the ideas page? Mar 13 16:55:08 And there is no mentor assigned for the stepwise mathematics Mar 13 16:55:23 sanujkul[m]: Even with proprietary technologies, there might be some premade modules that we can communicate with using existing Linux drivers and I2C/SPI interfaces. Have you checked into that at all? Mar 13 16:56:06 I have experience on i2c on pi Mar 13 16:56:17 @sanujkul: we’ve got CC13X boards and would like to work on gateway code and greybus over 802.15.4. Mar 13 16:56:21 * iamshankhadeep[m uploaded an image: Screenshot_2019-03-13-22-25-43-818_com.android.chrome.png (345KB) < https://matrix.org/_matrix/media/v1/download/matrix.org/RGWkvaMJtUHQhMLQKaCaKlkn > Mar 13 16:56:33 sanujkul[m]: We only have that low-power WAN topic on the page to give ideas, but we haven't listed a specific project for it. It would be up to you to come up with an appropriate project using those technologies and propose it. Mar 13 16:56:50 @jkridner:matrix.org: the Idea is in the link https://elinux.org/BeagleBoard/GSoC/Ideas Mar 13 16:57:09 oh, I thought you said it wasn’t there. Mar 13 16:57:33 hendersa +1 Mar 13 16:58:27 pranav_kumar[m]: There have been some discussions on the reference bus implementation project here in the channel over the past few weeks. Look back through the logs to get more details on what it might entail. Mar 13 16:58:39 history shows stepwise math comes from pac23 Mar 13 16:59:37 If I am concerned then I do know all the software skills needed for the project. So Wanted to dig deeper but no clue how. Mar 13 16:59:44 hendersa: thanks for the suggestion Mar 13 17:00:44 the exam requirement for Stepwise seems improbable Mar 13 17:01:56 perhaps a prototype could be made for a small scale UI and secure boot could be used for a product. Mar 13 17:02:36 hendersa: Sorry, I have missed looking for pre-made modules that we can communicate with using existing Linux drivers and I2C/SPI interfaces. But Mar 13 17:02:37 Thank you hendersa and jkridner Mar 13 17:03:08 @jkridner:matrix.org: so, do I need to pac23_ for the project? Or I need to submit my own idea in the elinux? Mar 13 17:03:29 @jkridner:matrix.org: so, do I need to talk to pac23_ for the project? Or I need to submit my own idea in the elinux? Mar 13 17:04:42 your proposal will be independent of the ideas entry, so you can keep your details there if it is based on the same idea. Mar 13 17:05:13 if you have a really different idea, you can make a new idea entry. Mar 13 17:06:12 talking to pac23 is good. but you might also draw in another mentor by talking out what you might do. Mar 13 17:07:11 @jkridner:matrix.org: okay. I got your point thanks a lot. Mar 13 17:07:47 vaishnav around? Mar 13 17:08:20 anyone looking at doing anything with my greybus proposal for click boards? Mar 13 17:08:52 jkridner[m]: What are your thoughts on the student proposing the Xen port to X15 on the Google Group? Do you think that is within our scope for GSoC? Mar 13 17:08:59 bug fixes on Adafruit_BBIO would be an easy one to manage. Mar 13 17:10:10 also, now that AI is being publicly discussed, that opens up some projects. maybe better Tensorflow integration. Mar 13 17:11:27 @jkridner:matrix.org: I didn't paid attention to the greybus idea.can I talk to you after researching about the idea? Mar 13 17:12:34 Better Tensorflow integration for PocketBeagle? Mar 13 17:12:36 sure, but I’m not around very consistently. Mar 13 17:13:01 beagleboard.org/ai Mar 13 17:13:16 much more powerful than PockerBeagle Mar 13 17:14:35 @jkridner:matrix.org: okay. Maybe you can give me your email ID I can email you or whenever you are here we can talk about greybus. Mar 13 17:14:47 Let me check on beagleboard.org/ai. Mar 13 17:15:05 i’m on beagleboard.org/about Mar 13 17:17:03 @jkridner:matrix.org: okay email Id is noted. Let me check on that Tensorflow integration and greybus and will get back to you in 2-3 days. Thanks a lot once again. Mar 13 17:18:55 hi iamshankadeep Mar 13 17:19:48 so basically waht you need for the stepwise mathcalculator is a matrix display that resembles the casio fx-990ex/es closely Mar 13 17:20:59 and a pocketbeagle with either a simcard module(if integrating sympolab/wolfram) or certain mathematical python libraries Mar 13 17:21:16 and how do you plan on emulating the keyboard without changing the form factor Mar 13 17:21:31 pac23: can it be developed with Qt at a low resolution and take hardware out of the critical path? Mar 13 17:21:32 for direct sum input in the format it is given on the question paper Mar 13 17:21:38 @pavankuppa:matrix.org: thanks a lot for reaching out. Okay listening every single thought with full attention. Mar 13 17:22:09 or Gtk+ or Electron/HTML Mar 13 17:22:19 yeah it can be jkridner Mar 13 17:22:25 or console. Mar 13 17:22:25 that would be pretty easy Mar 13 17:22:52 the hardware was to basically make a normal calculator used in engineering examination smarter while bein stealth Mar 13 17:23:26 but then the keyboard part is super hard to figure out/complete in one gsoc Mar 13 17:23:32 a software only approach would be nice Mar 13 17:24:07 Can we not create on touch screen module Mar 13 17:24:29 iamshankadeep read up on compiler construction and parsing,although the easiest way would be to use already available api(find out more about this) Mar 13 17:24:31 cool. I think the exam requirement could be done in some fun ways... one idea, SD cards handed out at the entry door? brightly colored ones and not allowing ones from students. Mar 13 17:24:36 Can we use machine learning for the input? Mar 13 17:25:20 Okay got it. Mar 13 17:25:33 I think the idea is pretty nice Mar 13 17:26:11 yeah you can,as long as the output in a stepwise format for example lets say there is a integration problem then its answer should be in the form as how you would solve it on paper Mar 13 17:26:16 step wise Mar 13 17:26:29 what do you mean by sd cards jkridner ? Mar 13 17:26:49 more fun would be to allow no uSD cards and boot the boards over USB at the start of the exam. No reboots however could make things tough if there were any hangups. Mar 13 17:27:27 well, pocketbeagle runs off microsd cards. Mar 13 17:27:36 oh that way,yeah Mar 13 17:27:47 i think there is some misturdstanding Mar 13 17:27:53 but can also be booted off of USB Mar 13 17:28:27 To do all the stepwise mathematics everything like integration,differentiation and all other things need to be handled explicitly. Is there any similar kind of libraries available from where I can the idea? Mar 13 17:29:03 so the backstory is : i had difficulty in my sophmore year of Software engineering doing math,because i have no backgorudn in it and i thought why not make a stealth calc using beaglebone/rpi that is the brain of it while being super discreete Mar 13 17:29:34 jkridner i was thinking using sdcards origanlly and using a push button startup integrating a thin iphone/similar battery for power Mar 13 17:29:53 because usb wont fit into the case right Mar 13 17:29:59 and wont be discreet then Mar 13 17:30:07 oh, so cheating is a desired outcome? Mar 13 17:30:14 yeah Mar 13 17:30:38 “discrete”? Mar 13 17:30:41 ah k. Mar 13 17:31:05 its just a fun idea, Mar 13 17:31:07 @jkridner:matrix.org: I do think so. Mar 13 17:31:13 that i thought of in between a math paper Mar 13 17:31:46 :p Mar 13 17:32:18 k. spi touchscreen and lipo same size as pocketbeagle might be small enough to fit in an altoids smalls mint tin. Mar 13 17:32:18 @jkridner:matrix.org: do you think this is a good idea that I can work on gsoc? Mar 13 17:32:41 if it fit in the tin, it could be pretty discrete. Mar 13 17:32:47 jkridner this is why i had put that this might be potentially illegal in the orignal msg i had sent you in november Mar 13 17:33:17 oh. i might have missed or forgotten. Mar 13 17:33:36 i’m fine with doing it as a proof of concept. Mar 13 17:33:37 jkridner but then the tin wont be allowed in to exams right,there is a spot check in exams so fiting this in the actual tx insturments 88/casio-990 body is the shiz Mar 13 17:33:55 yeah but then to avoid it being used,fitting it in a tin for example would be nice Mar 13 17:33:59 as long as no one here starts selling them. Mar 13 17:34:09 that way people wont get too many ideas Mar 13 17:34:33 lol Mar 13 17:34:40 ah, refitting a calc case would be excellent and provide a lot of fun interface hackery. Mar 13 17:34:42 @jkridner:matrix.org: I think no one will sale that. Mar 13 17:34:53 could just be considered an “upgrade”. Mar 13 17:35:01 yeah,i even had a diagram somewhere drawn ,will share it Mar 13 17:35:49 pac23: can you give me your email id? I would like to talk to you about this project. Mar 13 17:35:59 altoids smalls calculator is a good goal IMHO. Mar 13 17:38:46 yeah Mar 13 17:39:06 can a student be a mentor as well gsoc ? because i am kinda applying to a certain other org as a student Mar 13 17:39:17 i can always help as a unofficial mentor though Mar 13 17:39:25 if we picked a good OLED size/resolution, development could all be done in Qt or such. touch is a big question to me, but could be emulated with a mouse. of course, keys would just be keys. Mar 13 17:39:41 iamshankadeep pac23@fedoraproject.org Mar 13 17:39:54 pac23: pretty sure it is an either/or thing. Mar 13 17:40:21 pac23: Doesn't work like that in GSoC, you're either a student or a mentor, not both Mar 13 17:40:33 :/ Mar 13 17:40:35 sucks Mar 13 17:41:26 mentors don’t typically get paid. ;-) Mar 13 17:41:42 students do. Mar 13 17:41:52 hendersa: I would have some skin in the game for the parallel bus idea as well. Mar 13 17:42:02 i'll be here anyways to help Mar 13 17:42:09 * jkridner[m] needs to be better this year with rewarding mentors. Mar 13 17:42:23 AI boards for every mentor for sure. Mar 13 17:42:32 jkridner: Mentors have the opportunity to be invited for the mentor summit ;) Mar 13 17:42:50 Damn I really want that AI board. Mar 13 17:43:13 pac23: yup you are needed. Mar 13 17:43:19 Your one good proposal away. :-) Mar 13 17:43:21 Guest79507: Just throw your name in on the idea page under the mentors for it. Mar 13 17:43:31 actually I need you regarding that project. Mar 13 17:44:07 Guest79507: Has there been a year where we haven't been mentoring stuff together? Mar 13 17:44:33 * jkridner[m] needs to throw in some better AI ideas tonight. Mar 13 17:44:43 jkridner : Don't know if you saw my mail regarding BeagleLogic on the BeagleBone AI but throwing a FPGA in front of a 16 bit bus can lead to a lot of interesting stuff. Mar 13 17:45:12 I did see it. Mar 13 17:45:23 jkridner[m]: Maybe something with OpenCV for the AI? Mar 13 17:46:09 (continued from previous msg) - the parallel bus idea can lead to something interesting. Mar 13 17:46:34 maybe. the existing demos use OpenCV for some things, but not for model inference. Mar 13 17:47:56 abhishek: I think AI could do dual interfaces. 16 bit on one pair of PRUs and an analog scope interface (DAC) of some kind on the other. DMA usage should also be added. Mar 13 17:48:31 but, I think you should finish BeagleLogic Stand-alone first, personally. Mar 13 17:49:28 * jkridner[m] has to leave soon. Mar 13 17:49:53 Christi hasn't got back on how things are looking right now on the standalone. Should follow up. Mar 13 17:50:14 under a minute actually. Getting dropped at the airport to head to Texas. Mar 13 17:50:36 jkridner: okay bye then. Mar 13 17:50:58 Yes, you should, but your last message confuses that as it adds more moving pieces. Mar 13 17:51:08 bye all. Mar 13 17:51:13 jkridner: OK Mar 13 17:51:18 Bye Mar 13 17:51:40 jkridner[m]: Travel safe. Mar 13 18:28:32 jkridner Hi :) I have been out for vacation for the last two weeks and couldn't attend the meetings... I am currently working on adding Techlab support to the makecode target using the resources you have provided... hope to update the progress before next meeting Mar 13 18:30:53 also I am interested to work on the 'click board support under greybus' project and am going through the resources at the ideas page Mar 13 19:05:38 * ravikp7[m] very busy these days Mar 13 19:07:01 pac23, iamshankhadeep : stepwise calc seems like very fun project to do :-) Mar 13 19:09:34 jkridner: thanks for adding greybus over 802.15.4 to the idea, will look into it, otherwise only gateway wasn't sufficient for the gsoc timeline Mar 13 19:11:23 sanujkul: hey, let us know if you come up with a project idea on the lpwan after getting feedback today :) Mar 13 19:12:42 sanujkul: meanwhile, this may help with the research https://www.youtube.com/watch?v=7H50pv-4YXw Mar 13 19:18:58 jkridner: AI board as reward, I should work harder now ;) some beagleboard.org swag as well would be awesome! **** ENDING LOGGING AT Thu Mar 14 02:59:57 2019
