Finding a fulfillment house willing to work in low quanities in US near me has so far been fail. Just brought over 50 Ben Nanonotes to contractor last week. Should be selling later this month. 2010-10-08 08:17 well, let's say he exactly met the expectations I had into his "I will release code next week" 2010-10-08 08:17 I'm around the block for a while... :-) 2010-10-08 08:17 meanwhile we are actually moving, and code is free & open from day 1, how it should be 2010-10-08 08:17 djbclark: perfect, good to hear that 2010-10-08 08:17 I'm in for the long run, so no worries 2010-10-08 08:18 wolfspraul: Hallam? He is also still alive. I wasn't aware he had promised anything. 2010-10-08 08:18 we are trying to spend a bit more time to write up good readable news, with pictures and all 2010-10-08 08:18 that will also improve the communication among the core members like you 2010-10-08 08:18 otherwise our project is too diverse 2010-10-08 08:18 djbclark: sure we quipped over it back then. 2010-10-08 08:18 it's not his fault 2010-10-08 08:18 his employer won't let him release nada zip anything 2010-10-08 08:18 that simple 2010-10-08 08:19 what wonderful code shall we expect in 4 months ? (standard development time adjustment: add one, duplicate, then convert to the next higher unit) 2010-10-08 08:19 GPS firmware 2010-10-08 08:19 the stuff kristian paul works on 2010-10-08 08:19 ooh ! that would be nice 2010-10-08 08:19 yes 2010-10-08 08:20 santa claus also could remember the copyleft iphone this season... 2010-10-08 08:20 djbclark: if you are using an RSS reader, please add http://en.qi-hardware.com/feed/rss20.xml 2010-10-08 08:20 and help spreading the link 2010-10-08 08:20 is kristianpaul the guy who's doing GPS in an FPGA ? the project where we looked at the RF frontend chips ? i thought that was someone else 2010-10-08 08:20 wolfspraul: ah yeah I thought the useful stuff from him was the hardware component descrptions maybe; the code sounded like it would at least be in purgatory (where there are, of course, lots of attorneys) for months at minimum 2010-10-08 08:21 -> breakfast food 2010-10-08 08:21 wpwrak: yes, http://en.qi-hardware.com/wiki/GPS_Open_Stack 2010-10-08 08:21 wolfspraul: if by "using" you mean "have", sure, if you mean "actively have read anythin in the last few months", less so :-/ 2010-10-08 08:22 he, OK 2010-10-08 08:22 still spread that link if you can... 2010-10-08 08:22 wolfspraul: sure, I'll go dent it... 2010-10-08 08:23 yes! :-) 2010-10-08 08:23 thank you! 2010-10-08 08:23 that's the pure original qi news link 2010-10-08 08:23 no aggregated stuff 2010-10-08 08:23 100% copyleft hardware :-) 2010-10-08 08:24 wolfspraul: ah, nice. thanks ! i've been wondering if anything had come out of it. good to see that it's alive :) 2010-10-08 08:24 huh of course 2010-10-08 08:24 you are chatting with him every day :-) 2010-10-08 08:24 wpwrak: you are Werner, right? 2010-10-08 08:24 :-) 2010-10-08 08:24 it's the same guy working on the case for ben-wpan with his reprap 2010-10-08 08:25 he got a sige 4162 evb, and an antenna, and some other smaller stuff 2010-10-08 08:25 oh and a SIE board 2010-10-08 08:26 wolfspraul: hehe ;-) i just didn't know he was the one doing that GPS thing. he occasionally mentioned something about GPS, but relatively little and nothing that would "connect" it. 2010-10-08 08:26 oh, I see 2010-10-08 08:27 world view updated :) 2010-10-08 08:29 [commit] Werner Almesberger: fw/c2usb.conf: USB product ID assignment is now official http://qi-hw.com/p/f32xbase/77d6848 2010-10-08 08:29 grr. and i need caffeine. s/fw/hw/ # grmbl 2010-10-08 10:25 wpwrak: yes 2010-10-08 10:25 i just dont like spread loudly what is not done yet :) 2010-10-08 10:27 also is a huge learning curve, task i still doing almot every day 2010-10-08 10:27 almost* 2010-10-08 10:27 right now i want debug the GPC IC frontend output before go further 2010-10-08 10:28 thats why i want use SIE as scopemeter 2010-10-08 10:28 and is not GPS on FPGA initally (surelly will, but who knows) 2010-10-08 10:29 lets see how the ben can handle the GPS correlatiion/trackingÂ Â and no die in the try ;) 2010-10-08 10:38 kristianpaul: will you generate/collect a sample data stream to try on the Ben ? 2010-10-08 10:38 hmm 2010-10-08 10:38 nice idea 2010-10-08 10:38 kristianpaul: (scopemeter) hmm, but you have a digital output on the RF frontend. so why the scopemeter ? (besides generally being a useful thing to have around) 2010-10-08 10:39 wolfspraul: much nicer if the data you're trying to reproduce that bug with doesn't change every second ;-) 2010-10-08 10:40 well I also thought about it from a practical standpoint 2010-10-08 10:40 right now we only have one sige 4162 evb 2010-10-08 10:40 and they are hard to come by 2010-10-08 10:40 but if kristianpaul uploads sample data streams, more people can join development 2010-10-08 10:40 we 'virtualize' the evb :-) 2010-10-08 10:41 it also reminds me of a meeting I had at u-blox a while back, where they told me how some cameras had a system where the camera only stored the raw data stream when taking the photo, and it would be converted to the GPS location only later when the pictures are copied to the desktop 2010-10-08 10:41 (of course all with proprietary software) 2010-10-08 10:42 that way the cost of the gps solution in the camera would be much lower 2010-10-08 10:43 but crappier 2010-10-08 10:43 as you would be tied to their software 2010-10-08 10:43 sure, although that is not the fault of the hardware 2010-10-08 10:43 I know, it is simply a note regarding that particular product 2010-10-08 10:43 wolfspraul: (board access) yes, good point 2010-10-08 10:43 on the camera itself there are indeed few applications where the user would want to know the gps coordinates immediately 2010-10-08 10:44 bartbes: free the software and it's uncrappy again :) 2010-10-08 10:44 that's something they noticed, so the camera is simplified (the hardware), without the user noticing a lost feature 2010-10-08 10:44 that in itself is a good realization 2010-10-08 10:44 wolfspraul: well, if I have a camera I want to be able to take out my mem card and copy the photos, in this case with the gps position in it 2010-10-08 10:45 wolfspraul: and since we're all about making things chin^H^Heap .. :) 2010-10-08 10:45 though if the gps data is stored on the mem card it is already much better 2010-10-08 10:45 I don't know how they embed the data with the picture, in this case the raw data instead of the gps coordinate 2010-10-08 10:45 anyway we are diverting. it just came to my mind when werner spoke of 'sample data streams' 2010-10-08 10:45 bartbes: is there actually a "standard" way to put GPS data into EXIF ? 2010-10-08 10:45 heh 2010-10-08 10:46 I believe there is 2010-10-08 10:46 because essentially a 200kb data stream (a vague memory from that meeting) is the same as a gps coordinate 2010-10-08 10:46 just needs a bit of math :-) 2010-10-08 10:46 so where you move that math depends on the application/device type - why not... 2010-10-08 10:46 small details :) 2010-10-08 10:46 wpwrak: though if I remember correctly there are a few different formats, and some of them are actiually stored in the EXIF comment section.. 2010-10-08 10:46 wolfspraul: also helps a lot if you can debug your math on the PC 2010-10-08 10:47 bartbes: I am not saying I like the pile of proprietary crapware that will stand at the end of this, we are on the same page about that. 2010-10-08 10:47 bartbes: good. so at least some made a reasonable choice :) 2010-10-08 10:48 wpwrak: though wikipedia seems to *suggest* there is a standard way of adding it to ExIF 2010-10-08 10:48 wolfspraul: (proprietary) it's at least a choice that can be useful to have. besides, coming from us, it would be open anyway. so worst case, you'd need another open utility to decode the samples 2010-10-08 10:49 sure, like I said it's not the fault of the hardware 2010-10-08 10:49 the idea to drastically simplify the gps module/hardware in a camera because in that device it's enough to collect the raw data stream is a valid idea, I think 2010-10-08 10:52 wolfspraul: definitely. just like SDR moves the hard stuff into the CPU. so you move everything one further step down, towards less specialized equipment. 2010-10-08 11:08 having worked with OpenWrt to build 1.5 packages, I have to say this system is really great. 2010-10-08 11:14 aisa: did you have a chance to look into that owners/permission problem, whether you still have it? 2010-10-08 11:16 wolfspraul: btw, how about the ghostbusting band-aid ? 2010-10-08 11:17 wolfspraul: porting this package, jbofihe, has taken longer than I planned. 2010-10-08 11:17 the program compiles part of itself and then uses that to finish the build, 2010-10-08 11:17 wpwrak: another mail in my inbox 2010-10-08 11:17 ;-)) 2010-10-08 11:17 it's excellent. if it works we're done. 2010-10-08 11:17 so I've had to look at gforth package and do a lot of searching to get it working. 2010-10-08 11:17 I am planning on testing this permission problem next, after this package is successfully ported. 2010-10-08 11:18 I'm happy to report that as of this morning it is running on the NanoNote, 2010-10-08 11:18 but I still have at least one bug to fix. 2010-10-08 11:18 today was not a good day, I ran out of battery without noticing, after power cycle some files were corrupted (executables), I thought a few quick apt-get would fix it, but maybe I should not have been so quick as the problem got bigger, and so on 2010-10-08 11:18 wolfspraul: was that about the band-aid ? if yes, i'll switch the heap randomization off and rebuild avt2. then we'll see the truth, ugly or not 2010-10-08 11:18 of course 2010-10-08 11:18 (fs corruption) eek 2010-10-08 11:18 that's what I would do once I get to your mail 2010-10-08 11:19 amazing that you (think you) tracked it down so quickly. if that workaround works we're done. 2010-10-08 11:20 i still don't know what really causes it. but for that, i'd also have to compare kicad versions and so on. but that can wait :) 2010-10-08 11:21 (quickly) not really. albout a week :-( well, with several interruptions. 2010-10-08 11:21 nah 2010-10-08 11:21 we document it properly, and that's it. after a year we can check whether it's still needed. 2010-10-08 11:21 hehe :) 2010-10-08 11:22 rebuild is running. let's keep our fingers crossed :) 2010-10-08 11:26 maybe uninitialized variable somewhere? small compiler differences in the myriad of C++ constructor options 2010-10-08 11:26 there are many ways something like this can creep in 2010-10-08 11:26 the workaround (if it's stable and works) is fantastic I think 2010-10-08 11:26 effective! 2010-10-08 11:26 yes, my guess would be some uninitialized boolean for boldface on/off 2010-10-08 11:27 wpwrak: do you know the 1000 different ways of C++ constructors? 2010-10-08 11:27 wolfspraul: i'm not sure i want to ;-) 2010-10-08 11:27 that's a real jungle. I do not envy a compiler writer who has to implement this bug-free, somehow. 2010-10-08 11:27 you could easily study just constructors for a year or two 2010-10-08 11:28 i didn't know there were such a mess. thought they just get called and that's it 2010-10-08 11:28 amazing how a simple concept such a linear memory can be made so complex 2010-10-08 11:28 oh no 2010-10-08 11:29 but let's not continue the C++ rant :-) 2010-10-08 11:29 if that workaround works it's great! 2010-10-08 11:31 it's done. how do we like this ? http://projects.qi-hardware.com/schhist/board-qi-avt2/ 2010-10-08 11:35 wpwrak: (scopmeter) sure the SiGE EVB have pulse digital ouput, i'm just want debug the signal 2010-10-08 11:35 he 2010-10-08 11:35 perfect I think! 2010-10-08 11:36 wpwrak: I'll document this tomorrow, thanks a lot for the help! 2010-10-08 11:36 wpwrak: in teory this si square ouput, but it could get triangled due some reason related to capacitance load (i need read more about it) 2010-10-08 11:37 wolfspraul: yup thats the plan, upload the streams 2010-10-08 11:37 surelly :) 2010-10-08 11:37 wolfspraul: two more steps: 1) rebuild the rest too (there may be ghosts we haven't spotted yet), and 2) set things such that this survives a reboot 2010-10-08 11:37 i just want to make sure have a clean data aqusition process usign the Ben 2010-10-08 11:37 wpwrak: I'll do that, no worries 2010-10-08 11:38 kristianpaul: ah, just the signal integrity. i see. hmm, what sample rate do you expect to get ? 2010-10-08 11:38 wolfspraul: ok, so i'll leave all that to you :) thanks 2010-10-08 11:38 kristianpaul: (on the scopemeter) 2010-10-08 11:39 wpwrak: (generate data) yes is other idea simulate QI data froma fpga to the ben in order to test benchmarking 2010-10-08 11:41 wpwrak: (rate) there are 3 signal out, SYNC(2Mhz) , DATA (4bits per sync), CLK (8Mhz) 2010-10-08 11:41 yes, that too. ah, you'll still need to make that spi-to-spi cpld :) 2010-10-08 11:41 probably 2010-10-08 11:41 but i want see the sqare behavior before 2010-10-08 11:41 thats why i need the scopemeter 2010-10-08 11:42 i plan ignore the CLK 2010-10-08 11:42 kristianpaul: (rate) for signal integrty you need some multiple of that. some recommend 10x, but that's probably a bit excessive. still, 80 MHz is achievable. 2010-10-08 11:42 and just track SYNC and do internal timingns to get the right 4 bit data 2010-10-08 11:42 4 bit pulse data** 2010-10-08 11:43 wpwrak: you mean i need 80Mhz scopmeter to measure 8Mhz data 2010-10-08 11:43 ? 2010-10-08 11:43 why not get a decent bench scope ? :) there's an advantage in having a device with real controls that doesn't depend on the pc ... 2010-10-08 11:43 i dont have all that money 2010-10-08 11:43 yeah. well, it actually depends on the raise/fall time specification. 2010-10-08 11:44 isn't this a for-work project ? :) 2010-10-08 11:44 for-work? 2010-10-08 11:44 one that's part of your job 2010-10-08 11:44 nope 2010-10-08 11:44 (dunno what you're doing, actually) 2010-10-08 11:44 ah, pity 2010-10-08 11:45 my real-work is information security 2010-10-08 11:45 not much hardware then 2010-10-08 11:45 thats from all the money came from to bvuy reprap, fpga abnd otehr stuff 2010-10-08 11:45 but you can cupcake keys to the server cabinets ;-)) 2010-10-08 11:45 :p 2010-10-08 11:46 you should ask for a raise. explain them that the expensive hobbies make you more qualified ;-) 2010-10-08 11:47 i considered thata ctually 2010-10-08 11:47 hehe 2010-10-08 11:53 wpwrak: any way i like support this project :) 2010-10-08 11:53 wpwrak: in case my DIY scopmeter fail i think i could byt this http://shop.ebay.com/i.html?_nkw=scopemeter&_sacat=0&_odkw=scope&_osacat=0&_trksid=p3286.c0.m270.l1313# 2010-10-08 11:55 100 MHz, good price for that 2010-10-08 11:55 yeah 2010-10-08 11:55 but i wonder if the price is for real. that thing costs USD 2600 new. 2010-10-08 11:56 so if they sell it that cheaply, they either have no clue or it's broken 2010-10-08 11:56 ah, it's an auction. that's why. 2010-10-08 11:59 :/ 2010-10-08 11:59 amazing how the prices differ. one place sells it at USD 2100 refurbished. another has it at USD 1500, apparently new. 2010-10-08 11:59 wait where is 100Mhz i read it was 10Mhz.. 2010-10-08 11:59 http://www.aaatesters.com/Fluke-Fluke_105B_100MHz_2CH_2_5GSa_s_Scopemeter.html 2010-10-08 12:00 http://www.testequipmentconnection.com/products/936 2010-10-08 12:00 10 MHz would be completely useless :) 2010-10-08 12:00 damm 2010-10-08 12:00 it is 2010-10-08 12:00 ok 2010-10-08 12:00 hmm 2010-10-08 12:00 i need go to a lab then 2010-10-08 12:01 10 MHz would mean that you can see a 10 MHz sinus. so forget about the signal integrity of anything faster than 2 MHz :) 2010-10-08 12:05 :/ 2010-10-08 12:43 [commit] Juan64Bits: Routing image sensor. http://qi-hw.com/p/xue/ad23f9e 2010-10-08 12:47 [commit] Juan64Bits: Cleaning. http://qi-hw.com/p/xue/cc01f3c 2010-10-08 13:39 2000usd !! 2010-10-08 13:39 :( 2010-10-08 13:39 i think i need ask for a electronic lab in the local university 2010-10-08 13:50 aisa: does your work on wordgrinder mean that it can now be installed on a nanonote? 2010-10-08 13:55 it can. 2010-10-08 13:55 I should have marked the package as unbroken. 2010-10-08 13:55 it did not work for me on the factory image, 2010-10-08 13:55 but once I flashed to the latest build. 2010-10-08 13:55 wordgrinder works. 2010-10-08 13:55 I've not really exercised it, but it opens and writes. 2010-10-08 13:56 qbject: that last bit was all for you. 2010-10-08 13:58 Cool. Thanks. 2010-10-08 13:59 aisa: I realized after I asked that I should probably avoid using it and keep to my own project, but it's good to know that it's out there. :) 2010-10-08 13:59 here, let me port more software for you ;-) 2010-10-08 14:00 Heh. Well, now that you mention in... :-P 2010-10-08 14:00 in -> it 2010-10-08 14:01 kristianpaul: do you have it far to bogota ? 2010-10-08 14:11 is watching http://www.youtube.com/watch?v=9u-MczVpkUA 2010-10-08 14:11 after a post to the mailing list. 2010-10-08 14:56 aisa: how's it looking? 2010-10-08 14:58 qbject: what, the video? 2010-10-08 14:58 I cross posted it to another list, I enjoyed it. 2010-10-08 15:00 Very cool. I'll watch it tonight while I'm duct taping Dingoo libs into my nn. 2010-10-08 15:01 I spent a lot of time getting a package to generate files on my host, only to realize they were platform dependent and didn't work on my NN. 2010-10-08 15:01 I did get a package out of it, which I can use to generate those data files. 2010-10-08 15:02 that's my next duct tape project. 2010-10-08 15:02 I know nothing about Dingoo... 2010-10-08 15:02 goes to investigate. 2010-10-08 15:03 aisa: NN's less productive but no-less motivating bretheren. 2010-10-08 15:04 ah, cool. 2010-10-08 15:04 Don't get too caught up playing POWDER ;-) 2010-10-08 15:05 Never tried it, but okay. 2010-10-08 15:05 it's a roguelike for platforms like the dingoo. 2010-10-08 15:06 Ach. Meritous is the crawl I'm pursuing atm. 2010-10-08 15:06 And OpenTyrian. 2010-10-08 15:07 And other various modern interpreters for old content. 2010-10-08 15:15 aisa: oo. POWDER does have the sort of pixels I love. 2010-10-08 15:16 after reading about Meritous and OpenTyrian I had to forget they existed.Â Â At least for now ;-) 2010-10-08 15:16 I do plan on porting POWDER to the NN. 2010-10-08 15:16 Not sure of my timeline yet. 2010-10-08 15:17 it's not in my current sprint. 2010-10-08 15:20 aisa - before you get carried away, I think zear has already done so, though I don't know the status of his port: http://downloads.qi-hardware.com/people/zear/games/ 2010-10-08 15:20 great! 2010-10-08 15:20 If you REALLY want to have to forget that something exists, take a look at ASCIIpOrtal 2010-10-08 15:21 downloads 2010-10-08 16:11 wpwrak: 12 hrs by ground 2010-10-08 16:12 wpwrak: i live in Buga, is like 450~ away 2010-10-08 16:12 wpwrak: why? 2010-10-08 16:13 away from here* 2010-10-08 16:34 wpwrak: if i dont get the ost of scopemeter i'll trust signaling (glup!) and move to a logic analizer or sort of.. 2010-10-08 16:38 09:42 < wolfspraul> it also reminds me of a meeting I had at u-blox a while back, where they told me how some cameras had a system where the camera only stored the raw dataÂ Â stream when taking the photo, and it would be converted to the GPS location only later when the pictures are copied to the desktop 2010-10-08 16:38 yeah thats reelly usefull 2010-10-08 16:38 as cameras can correlate all that data :) 2010-10-08 16:38 cant* 2010-10-08 16:39 i'm not sure but u-box seems to use the same SiGE chip i have or same family** 2010-10-08 16:45 wpwrak: The CLK_OUT, DATA and SYNC output drive is set to maximum by R6 = 0R pulling SE4162T RVI pin 12 2010-10-08 16:45 to LDO_OUT pin 24. RVI pin can be left open circuit for minimum output drive (7.5pF load). The GPS 2010-10-08 16:45 clock and data outputs are slew rate limited to minimize coherent feed-round interference which would 2010-10-08 16:45 otherwise de-sensitize the radio. As the load capacitance increases the higher frequency clock will tend 2010-10-08 16:45 towards a triangular waveform. In most practical applications the output drive should be more than 2010-10-08 16:45 adequate to drive the combined PCB and processor input load capacitance. However, problems may 2010-10-08 16:45 occur with large development platforms. In such cases a local, triple buffer for the clock and data lines 2010-10-08 16:45 may be required. Consideration of the total load capacitance should be made when viewing the condition 2010-10-08 16:45 of the clock waveform with a standard 11pF scope probe. 2010-10-08 16:46 that really worry me, thats why i need xscope, but i can guess this will happen and just implement they buffer they said.. 2010-10-08 16:46 or avoid clock 2010-10-08 16:46 may be 2010-10-08 16:52 i just compiled a "Hello, world!" on Ben with gcc, under OpenWRT :) 2010-10-08 16:53 now to create a usable Makefile 2010-10-08 16:54 kyak: awesome. 2010-10-08 16:56 kyak: ohh? 2010-10-08 16:56 kyak:Â Â ported gcc? how you achieved that? 2010-10-08 16:56 kyak: great :) 2010-10-08 17:01 kristianpaul, basically fighting with autocrap build system I guess :o) 2010-10-08 17:02 lekernel: ;) 2010-10-08 17:04 kristianpaul: (bogota) ah, i was thinking that carlos' group could help you with measurements. but 12 h is a little far. 2010-10-08 17:05 wpwrak: well i'm just finished writing a mail to a profesor i know from the local public univesity here, 2010-10-08 17:05 i'm now they hav lot of scopemeters 2010-10-08 17:05 i used soem of then 2010-10-08 17:05 but i'm not stduying there 2010-10-08 17:06 so i asked him for some help and support 2010-10-08 17:07 let's hope they can do something for you 2010-10-08 17:08 wpwrak if were in bogota (NOO ;)) i think anyway carlos keep busy with its courses and students so let him work :) 2010-10-08 17:08 me too := 2010-10-08 17:08 seems that you could just start with R6 = 0R. given that the data clock is constant, you'd notice quickly if anything is amiss 2010-10-08 17:09 yup 2010-10-08 17:09 kristianpaul: carlos would not have to assist you _personally_ ;-) 2010-10-08 17:10 wpwrak: sure but i know equipment is expensive and he dont know nothing about me so.. at least that count 2010-10-08 17:10 anyway i'm not near to bogota to worry about it :) 2010-10-08 17:12 in the other hand this professor know me since years go so is different ask for soemthing like this 2010-10-08 17:14 kristianpaul: for measuring the clock frequency, you can use the approach i used for ben-wpan/cntr: implement a large (> 32 bit) free-running counter, read it from a pc, and synchronize with NTP 2010-10-08 17:15 :O 2010-10-08 17:15 NTP isn't extremely accurate bit it's immune to drift. so you can implement an arbitrarily precise frequency counter if you're willing to wait long enough 2010-10-08 17:15 s/biy/but/ 2010-10-08 17:15 i'm doing ! 2010-10-08 17:15 gah 2010-10-08 17:15 for mlkymist 2010-10-08 17:15 but is kind of crude yet 2010-10-08 17:16 but can be improved :) 2010-10-08 17:16 (already) great ! 2010-10-08 17:16 hmm you gave me an interesting idea 2010-10-08 17:17 i used "cntr" to check that the transceiver has a clock that's better than +/- 30 ppm. i can get a measurement accuracy of a few ppm quite easily. a frequency counter with the same precision would cost something like USD 2-3k 2010-10-08 17:18 of course, it would be faster :) 1 s vs. 20 minutes :) 2010-10-08 17:18 :) 2010-10-08 17:28 i wish my scope had a larger sample memory. debugging usb-driven communication (ft232 bit-banging) is quite da pain. 1 MHz output change rate with delays of several ms between bursts. i either see only a small fraction of even the simplest session or it's with an unusably low sample rate :-( 2010-10-08 17:29 sigh. why or why do those nice new rigols with 140 MSa have to be so expensive ... 2010-10-08 17:33 sigh 2010-10-08 17:43 checks bitscope.com 2010-10-08 18:53 that ft232 is a weird beast. seems that set_bitmode can bypass a write. 2010-10-08 19:37 also nice: in peak detect mode, my scope doesn't combine min/max samples but shows them one after the other, "inventing" nice glitches. haven't used peak detect mode for a while, but i think with older firmware, it didn't do this. 2010-10-08 20:54 wpwrak: the milkymist 'memory instability' bug is fixed, turned out to be a software problem in usb event handling 2010-10-08 20:54 just fyi 2010-10-08 20:54 lots of time went into this, but at least we got some stability improvements in the rc2 board out of it, that (assuming there are no regressions) should be a good thing in general 2010-10-08 20:55 wow. sounds like a pretty non-obvious connection 2010-10-08 20:55 yeah, sometimes you find a lot of other problems when chasing a bug long enough ;-) 2010-10-08 20:56 well, congratulations to the mikymisters ! :-) 2010-10-08 20:59 wolfspraul: seems that you have enough stuff already for a community news update :-) 2010-10-08 21:00 oh 2010-10-08 21:01 yes 2010-10-08 21:01 tons 2010-10-08 21:01 it's a lot of work to turn it into high quality news though 2010-10-08 21:01 I think I will work on a milkymist press release for 27c3 2010-10-08 21:01 try to get a quote from Lattice, etc. 2010-10-08 21:02 that's another thing that was missing in the Nanowar release - a quote 2010-10-08 21:08 maybe a good strategy for the community news would be to have a frequency or quantity trigger. if you have enough items, don't wait for more. that way, you avoid getting a small encyclopedia every once in a while (which many people won't read with the same amount of attention something smaller would get). 2010-10-08 21:09 totally agree 2010-10-08 21:09 the frequency trigger would be a timeout to show that the project is still alive 2010-10-08 21:09 I may need to move some of the 11-1 stuff into 12-1 2010-10-08 21:09 but one by one 2010-10-08 21:09 also, even though schhist, or 2.6.36 inclusion, would justify a proper press release of their own, I don't have enough time right now to do it 2010-10-08 21:10 so it will just show up as an entry in the community news... 2010-10-08 21:12 community news are fine for such things. they're not big enough to make it into, say, heise newsticker anyway 2010-10-08 21:12 I think we should only do a press release when we reach some minimum quality level, with regards to the text, pictures, quote, etc. 2010-10-08 21:13 and also on the release day of the press release we need someone full-time to follow up with media 2010-10-08 21:13 yes, that too. and have something substantial enough. a product launch, for example. or some major new use(r) 2010-10-08 21:13 so unless we have that capacity, it's better to bring it nicely in the community news rather than have a lot of failed press releases 2010-10-08 21:13 yeah, i saw how you explained it to tuxbrain. quite a bit of work :) 2010-10-08 21:13 sure 2010-10-08 21:14 but think about how much work whatever the press release is talking about is 2010-10-08 21:14 if you want your press release to be picked up, you are competing with others and they put substantial efforts on getting their word out... 2010-10-08 21:14 sure. still, didn't expect that you'd actually need a propagation-around-the-world schedule. well, never thought about it. 2010-10-08 21:17 well that's my suggestion and I have seen it like that in recent years. if someone knows a better way, please late us know... 2010-10-08 21:17 these things are changing, it depends on how the media is working 2010-10-08 21:18 I remember even 10 years ago it was all about the address list (snail mail) you had 2010-10-08 21:18 so on the day of the press release, you would mail out x00 letters to the 'secret list' that only your PR guy had and would never share with you 2010-10-08 21:19 so at least that has been blown wide open now 2010-10-08 21:19 it does sound quite reasonable. i'm more the "fire and forget" type. but i can see how that approach would fail miserably in this case. 2010-10-08 21:19

personal email addresses of any media you like 2010-10-08 21:19 open hardware, open PR ;-) 2010-10-08 21:20 I think something new in recent years is that stories are 'pulled' 2010-10-08 21:20 journalists are so overloaded with bad quality stuff, that they rather contact known PR agents themselves, and work with them to craft/time interesting stories 2010-10-08 21:20 heh :) interesting 2010-10-08 21:20 but who knows, we just do step by step, see what works, adapt, etc. 2010-10-08 21:21 and nice for the PR agents. strengthtens their position 2010-10-08 21:21 definitely 2010-10-08 21:21 they found a replacement for the 'address list' they guarded like a state secret 10+ years ago 2010-10-08 21:21 everybody has that now 2010-10-08 21:21 but the result is flood, and... things turn around and the PR pro is back in business... :-) 2010-10-08 21:23 back then they often were an overpriced mailing service, leaning back and sitting on their list 2010-10-08 21:23 I do think now they have to work harder on quality, so someone will contact them to pull stuff 2010-10-08 21:23 fat cat biz :) 2010-10-08 21:24 if I had more money I would work with a PR agent right away 2010-10-08 21:24 works like a multiplier on whatever you have 2010-10-08 21:25 could we have someone in the community who'd have channels ? there are some people who seem to have more of a journalistic profile than a developer profile 2010-10-08 21:26 or perhaps you already have better access anyway 2010-10-08 21:26 help is always good 2010-10-08 21:26 I don't know, it's a good question 2010-10-08 21:26 xiangfu continues to work on the fped Debian package 2010-10-08 21:26 should be almost done 2010-10-08 21:27 as for getting it into Debian, we might need a sponsor or so (I think first xiangfu uploads it to mentors.debian.net, he can do that himself, and after that it needs to be pulled up by higher authorities) 2010-10-08 21:27 I was thinking about contacting Jan Luebbe, he's a Debian developer and may have the powers 2010-10-08 21:28 ah, interesting process :) 2010-10-08 21:28
