2011-10-10 06:44 <kyak> viric: the newsbeuter thing is getting really slow when it is 15000+ articles in a cache. It also uses around 250 Mb of RAM at this point -\ Have you tested offrss in such harsh conditions?
2011-10-10 06:51 <qi-bot> The build was successfull, see images here: http://fidelio.qi-hardware.com/~xiangfu/compile-log/openwrt-xburst.full_system-10092011-0220/
2011-10-10 06:53 <xiangfu> needs prepare the next nanonote release. linux 3.1 and merge all atBen stuff to next release.
2011-10-10 06:53 <xiangfu> 1.5 month passed.
2011-10-10 06:54 <wolfspraul> yes, great! :-)
2011-10-10 07:13 <kyak> indeed!
2011-10-10 07:17 <viric> kyak: hmm I've maybe 4000 articles, with no slowdown, and almost constant ram use
2011-10-10 07:17 <viric> kyak: it's up to the filesystem cache
2011-10-10 07:37 <kyak> this is great
2011-10-10 09:55 <wolfspraul> kristoffer: you've asked Andrew Holme about the license of this GPS work already, right?
2011-10-10 09:55 <wolfspraul> then I don't need to send more mails...
2011-10-10 10:06 <C-Keen> the nanonote is an excellent zcode player for long train travels! Thanks guys :)
2011-10-10 10:12 <viric> C-Keen: what is that?
2011-10-10 10:13 <C-Keen> viric: playing text adventure games
2011-10-10 10:14 <viric> ah ok
2011-10-10 10:19 <viric> I thought text adventure games were more for devices with easy typing
2011-10-10 10:30 <wolfspraul> C-Keen: zcode - is that in the image, a package, or you built it yourself?
2011-10-10 10:30 <wolfspraul> we ported frotz to the NanoNote once upon request by Nick Montfort, who then also made sure his Curveship software runs on the Ben
2011-10-10 10:31 <C-Keen> wolfspraul: it is a package I found on the wiki, the name of the zcode interpreter is zoom
2011-10-10 10:31 <C-Keen> wolfspraul: interesting, I will have a look at nick's port
2011-10-10 10:31 <wolfspraul> yes, definitely
2011-10-10 10:32 <wolfspraul> do you happen to have a url to the package? if you use it we should include it by default :-)
2011-10-10 10:35 <C-Keen> wolfspraul: ah sorry, I was wrong. I have been using frotz actually. So all is good!
2011-10-10 10:36 <C-Keen> just checked
2011-10-10 10:47 <wolfspraul> you played directly with frotz?
2011-10-10 10:47 <wolfspraul> or you had some game that used frotz?
2011-10-10 10:48 <C-Keen> frotz is an interpreter that reads zcode images of games
2011-10-10 10:48 <C-Keen> I have played with it directly
2011-10-10 10:48 <C-Keen> the typing is still a bit awkward for me on the keyboard
2011-10-10 11:10 <wolfspraul> C-Keen: are there any resources/sites for zcode games?
2011-10-10 11:10 <wolfspraul> free stuff that we could just include
2011-10-10 11:17 <C-Keen> tons of it, there are even new games created every year. the "official" archive is at ifarchive.org
2011-10-10 12:07 <wolfspra1l> C-Keen: excellent link, thanks!
2011-10-10 12:07 <wolfspra1l> is all that stuff freely licensed?
2011-10-10 12:07 <wolfspra1l> do you think we can or should bundle some with the Ben?
2011-10-10 12:08 <wolfspra1l> ah well, they make their life easy :-) http://www.ifarchive.org/misc/license.html
2011-10-10 12:08 <viric> I'm very bad at interactive fiction
2011-10-10 12:08 <wolfspra1l> what does that mean in practice?
2011-10-10 12:08 <wolfspra1l> most of the stuff is not free?
2011-10-10 12:08 <wolfspra1l> or most is?
2011-10-10 12:10 <wolfspra1l> C-Keen: can you point me to your top-10 or so (or 5 or 3) zcode games on ifarchive.org?
2011-10-10 12:12 <wpwrak> viric: try this:  apt-get install tads3; wget http://mirror.ifarchive.org/if-archive/games/tads/Rematch.gam; t32run Rematch.gam
2011-10-10 12:13 <viric> wpwrak: debian not spoken
2011-10-10 12:13 <wpwrak> viric: yum install ? ;)
2011-10-10 12:13 <viric> nix :)
2011-10-10 12:13 <wpwrak> send your kid to school ! :)
2011-10-10 12:14 <viric> hehe
2011-10-10 12:15 <viric> I've played some 'instead' games
2011-10-10 12:15 <viric> http://code.google.com/p/instead/
2011-10-10 12:16 <wpwrak> "rematch" is quite unique. very out of the box.
2011-10-10 12:17 <wpwrak> you'll notice that by the time you die (in the game) ;-)
2011-10-10 12:23 <C-Keen> wolfspra1l: sure! http://ifarchive.org/if-archive/games/zcode/LostPig.zblorb http://ifarchive.org/if-archive/games/zcode/anchor.z8 http://ifarchive.org/if-archive/games/zcode/photopia.z5 http://ifarchive.org/if-archive/games/zcode/photopia.z5 [more]
2011-10-10 12:24 <wolfspra1l> great!
2011-10-10 12:24 <wolfspra1l> thank you!
2011-10-10 12:24 <viric> wpwrak: ah ok I may try :)
2011-10-10 12:25 <wpwrak> viric: actually, the qtads engine may be better than tads3, because it has a command line history. you'll need that :)
2011-10-10 12:26 <wpwrak> viric: here's a bit more background. and a link to the solution: http://www.wurb.com/if/game/1114
2011-10-10 12:26 <C-Keen> http://ifarchive.org/if-archive/games/zcode/vgame.z8 http://ifarchive.org/if-archive/games/zcode/awaken.z5 http://ifarchive.org/if-archive/games/zcode/adverbum.z5 http://ifarchive.org/if-archive/games/zcode/Savoir-Faire.zblorb and lots of others
2011-10-10 12:26 <viric> ah, of course I *never* looked at a solution
2011-10-10 12:27 <C-Keen> wolfspra1l: ^
2011-10-10 12:27 <wolfspra1l> that's a great start
2011-10-10 12:27 <C-Keen> wolfspra1l: see also http://www.intfiction.org/forum/viewtopic.php?f=23&t=3272&hilit=top+10 for ideas, but this list also contains non zcode games or nonfree games
2011-10-10 12:27 <wolfspra1l> those are all freely licensed?

2011-10-10 14:21 <zrafa> hi
2011-10-10 14:24 <zrafa> wpwrak: you there? .. some pm says about mmc cmd  :  Each command token is preceded by a start bit (0)
2011-10-10 14:24 <zrafa> start bit is 0.
2011-10-10 14:24 <zrafa> and succeeded by an end bi
2011-10-10 14:24 <zrafa> t 1.
2011-10-10 14:25 <zrafa> (sorry the bad paste)
2011-10-10 14:25 <zrafa> well, if the clock is enought slow like you suggested
2011-10-10 14:26 <zrafa> I should check the CMD for any bit 1 right? (in order to know when to stop the controller)
2011-10-10 14:27 <zrafa> wpwrak: and no just waiting for the final bit 1. I mean, we just want to have cmd = 1, so I guess that 
2011-10-10 14:28 <zrafa> wpwrak: any bit = 1 in CMD bit is okey right? (I ask because I understood firstly to wait for the final bit 1, but I think now that you meant any cmd bit = 1)
2011-10-10 14:32 <zrafa> some pm says = 4740 pm says :)
2011-10-10 15:07 <kristianpaul> have a trivia http://puu.sh/6MX3
2011-10-10 15:07 <wpwrak> zrafa: back :)
2011-10-10 15:08 <wpwrak> lemme find a good SD/MMC reference ...
2011-10-10 15:14 <wpwrak> here we go: https://www.sdcard.org/downloads/pls/simplified_specs/Part_1_Physical_Layer_Simplified_Specification_Ver_3.01_Final_100518.pdf
2011-10-10 15:14 <wpwrak> the SD command structure is on page 58
2011-10-10 15:16 <wpwrak> you can set the command index and the argument to anything you want. so you could just make them all 0 or all 1 and then try to catch the right clock level. either by polling the i/o or by predicting the time from the start of the command to the middle of the corresponding clock phase.
2011-10-10 15:18 <wpwrak> well, you probably don't even need to worry about command and value. there are both fixed 1 and 0 bits in the structure, so you can just use one of these
2011-10-10 15:18 <zrafa> wpwrak: hey
2011-10-10 15:20 <wpwrak> MMC has a bit more low-level details. lemme see if there's a good description of the clock
2011-10-10 15:20 <zrafa> wpwrak: first bit is 0 and last bit is 1 in a cmd command, but if I catch any bit 1 in CMD in the middle of a transmision that would be oeky for our plans right?
2011-10-10 15:23 <zrafa> no more low level details please ;-)
2011-10-10 15:24 <wpwrak> our good friends in russia have a registration-free copy: http://yourcmc.ru/wiki/images/5/55/EMMC_JESD84-A441.pdf
2011-10-10 15:24 <wpwrak> page 194
2011-10-10 15:25 <wpwrak> the original is here: http://www.jedec.org/sites/default/files/docs/JESD84-A441.pdf
2011-10-10 15:28 <wpwrak> you shouldn't need anything but the first two bits. see page 8 of the SD physical layer spec. start bit is 0, transmitter (direction) bit is 1
2011-10-10 15:29 <kristianpaul> wolfspraul: i wrote him yes, dunno if kristoffer did it too 
2011-10-10 15:32 <wpwrak> so if you set the clock to frequency f, you'll have CMD = 0, CLK = 0 around t = X (but you don't know for how long), CMD = 0, CLK = 1 around t = X+1/4f, CMD = 0, CLK = 0 around t = X+3/4f, CMD = 1, CLK = 1 around t = X+5/4f, and CMD = 1, CLK = 0 around t = X+7/4f
2011-10-10 15:32 <kristianpaul> wolfspraul: his words "I had not thought about licensing."
2011-10-10 15:33 <wpwrak> "i was too busy killing AGPS" ;-)
2011-10-10 15:33 <kristianpaul> ;)
2011-10-10 15:33 <kristianpaul> but i asked again, about what he think about other people re-using its work, and i introduce him this irc and qi-hw
2011-10-10 15:36 <kristianpaul> no reply yet, that mail was from yday
2011-10-10 15:37 <wpwrak> zrafa: e.g., if you set the MMC bus clock to 250 kHz, you should see the following pattern: (CMD, CLK) = (0, 1), (0, 0), (1, 1), (1, 0)
2011-10-10 15:38 <wpwrak> zrafa: each of these four values should be stable for about 2 us
2011-10-10 15:39 <wpwrak> zrafa: now, if you want to be sure you hit the right combination, you would wait 1 us until after the value has been set. that way, you can err by about (-1 us, +1 us) and still get the desired setting
2011-10-10 15:40 <wpwrak> so this would be X+0*2+1 us, X+1*2+1 us, X+2*2+1 us, X+3*2+1 us
2011-10-10 15:40 <wpwrak> X is the time between telling the MMC controller to send the command and the beginning of the transmission
2011-10-10 15:42 <zrafa> kristianpaul: (now I need ten days more to understand that werner just wrote  ;-) ) 
2011-10-10 15:42 <wpwrak> MSC_CMDAT.INIT controls whether 80 clocks are added before the command or not. you don't want that ;-)
2011-10-10 15:42 <wpwrak> bah, it's easy :)
2011-10-10 15:43 <zrafa> wpwrak: saved. I just read the page 8 and I see those first two bits. Then
2011-10-10 15:44 <kristianpaul> zrafa: ;)
2011-10-10 15:44 <DocScrutinizer> haha, low level fun? :-)
2011-10-10 15:45 <wpwrak> zrafa: have you been able to requisition a scope ? seeing what actually happens will help a lot :)
2011-10-10 15:45 <zrafa> wpwrak: sorry, I do not understand yet why CLK changes, because I have not read well about clk. Let me a while (I di not found that at 4740 pm)
2011-10-10 15:49 <wpwrak> the bus clock CLK changes to indicate then the data on the bus is valid. see page 194 of http://yourcmc.ru/wiki/images/5/55/EMMC_JESD84-A441.pdf
2011-10-10 15:51 <wpwrak> i.e., data inputs and outputs must be stable when CLK raises from 0 to 1
2011-10-10 15:52 <wpwrak> ah, about the values ... what i wrote is probably wrong. more likely it's (0, 1), (1, 0), (1, 1) (x, 0)
2011-10-10 15:52 <wpwrak> (i.e., the data is stable on the rising edge of CLK but changes on the falling edge)
2011-10-10 15:54 <wpwrak> (x would be the first bit of the command)
2011-10-10 15:54 <wpwrak> so you would have (1, 0) at t = X+1 us and (0, 1) at t = X+3 us. couldn't be any easier :)
2011-10-10 15:57 <zrafa> wpwrak: no scope yet.. Maybe this week
2011-10-10 16:05 <kristoffer> what
2011-10-10 16:05 <kristoffer> people keep paging me and then run off
2011-10-10 16:06 <kristoffer> kristianpaul, whats the licensing you are talking about? Feel like Ive missed something
2011-10-10 16:07 <kristianpaul> kristoffer: about this project http://www.holmea.demon.co.uk/GPS/Main.htm
2011-10-10 16:10 <kristoffer> kristianpaul, sweet :) It appeals to my nerdy side. Looks like a cheap design also
2011-10-10 16:10 <wpwrak> seems that there are at least two FPGA boards he didn't show :)
2011-10-10 16:11 <wpwrak> (but then, with, say, M1, we have a big fat FPGA that should be more than sufficient for the rest of the processing)
2011-10-10 16:11 <kristoffer> It would be worth alot to have that as an open design so can see what you are all excited about.
2011-10-10 16:14 <wpwrak> it would be even better to get him interested in joining kristianpaul's little project. he visibly knows his signal processing incredibly well.
2011-10-10 16:15 <wpwrak> if he "just" opens the design, that may still be too difficult for mere mortals to understand ...
2011-10-10 16:15 <kristianpaul> wpwrak: yes i already asked that too :)
2011-10-10 16:15 <wpwrak> i find it particularly interesting that he just eliminated AGPS with a little FFT. some companies are building whole subcultures around the "A" in AGPS ...
2011-10-10 16:15 <kristianpaul> and talk about milkymist, etc, same history :)
2011-10-10 16:16 <kristianpaul> wpwrak: how you get that relation between fft and agps?
2011-10-10 16:20 <wpwrak> look in section "Search": "A "warm start" using almanac data to predict positions and velocities still requires a code search."
2011-10-10 16:20 <wpwrak> and then "This GPS receiver uses an FFT-based algorithm that tests all code phases in parallel. From cold, it takes 2.5 seconds on a 1.7 GHz Pentium to measure signal strength, Doppler shift and code phase of every visible satellite."
2011-10-10 16:21 <wpwrak> so, as i understand it, no almanac needed
2011-10-10 16:25 <kristianpaul> ah, i see you point, so you think GPS receiver are lasy now becaue relay on AGPS for fasttest fixes when they could just do more things in parallel?
2011-10-10 16:31 <wpwrak> i'm not quite sure what the story is. maybe he discovered something new. maybe i'm just not up to date. maybe his approach has drawbacks. maybe i completely misunderstand.
2011-10-10 16:31 <wpwrak> but i'm curious what the truth is :)
2011-10-10 16:42 <kristianpaul> for me is not new :-)
2011-10-10 16:44 <kristianpaul> i mean i had read like 3 books all pointed almost same technquies for signal tracking
2011-10-10 16:44 <wpwrak> ah, you knew about this ? okay, maybe i just missed that then. i just remember that AGPS was all the rage some five years ago
2011-10-10 16:44 <wpwrak> heh, okay :)
2011-10-10 16:49 <kristianpaul> actually fft is ideal for software based processing
2011-10-10 16:49 <kristianpaul> i dont expect tosee that on hw, i think PLL is better aprouch in that side
2011-10-10 16:49 <kristianpaul> or something like namuru like a correlator and a baseband processor
2011-10-10 16:50 <kristianpaul> (baseband processor) did not exits at least in open/free way yet :)
2011-10-10 17:39 <kristianpaul> wpwrak: but yes i already asked him to about why did not add processing stuff on the fpga
2011-10-10 17:47 <viric> hm memstat needs rework on 3.x
2011-10-10 17:50 <viric> kyak: offrss may take ~1MB of RAM for the amount of posts you said
2011-10-10 17:59 <viric> hm maybe I'm exagerating even.
2011-10-10 17:59 <viric> 500KB? :)
2011-10-10 18:02 <kyak> viric: i already shut down newsbeuter for good :) it is the first step towards offrss
2011-10-10 18:03 <viric> haha
2011-10-10 18:11 <viric> kyak: all the ram offrss takes is to load a file with 15000 lines.
2011-10-10 18:11 <viric> (for 15000 articles)
2011-10-10 18:16 <kyak> viric: actually, my requirements are quite bigger.. I have around 3500 new items every day
2011-10-10 18:16 <kyak> viric: is there "mark all as read"?
2011-10-10 18:17 <kyak> can't seem to find it..
2011-10-10 18:18 <kyak> heh, the pdf looks really cute :) it's adapted for the small screen
2011-10-10 18:21 <kyak> hm, having spaces in feed's name is not allowed?
2011-10-10 18:22 <kyak> ah, it's a pity -\
2011-10-10 18:25 <wpwrak> in printable ASCII we trust :)
2011-10-10 18:32 <kyak> the PDF has no pictures, so you are probably right :)
2011-10-10 18:53 <viric> kyak: what would that mean? mark all as read? do you plan to lie? ;)
2011-10-10 18:53 <viric> kyak: why would you want to get 3500 posts every day, and mark all as read, storing them forever?
2011-10-10 18:54 <viric> kyak: maybe you should visit a specialist :)
2011-10-10 18:54 <viric> kyak: I've not programmed anything to allow removing data, because I've not needed it. But it looks like you will need it
2011-10-10 18:58 <wpwrak> viric: i think with 3500 posts a day, the only way to survive is by just marking them read - without actually reading them ;-)
2011-10-10 18:58 <viric> wpwrak: looks like so :)
2011-10-10 18:59 <viric> maybe it's me who makes a weird use of the reader, having hundreds of articles "still pending read"
2011-10-10 18:59 <viric> kyak: put offrss under stress :)
2011-10-10 19:03 <kyak> viric: it's just that we have different uses for rss.. i use it primarily to track torrents. and i'm really good at going through the list and spotting what i need, and then marking the rest as read :)
2011-10-10 19:04 <kyak> especially when i have a list of regexpes to higlight it for me :)
2011-10-10 19:06 <wpwrak> 3500 torrents per day. man, i want your bandwidth !
2011-10-10 19:06 <kyak> then, even on a news site rss you wouldn't click 'mark read' on each article, but rather read the articles that caught your eye and then mark the rest as read
2011-10-10 19:08 <kyak> wpwrak: it's the hard disk space that's important :)
2011-10-10 19:09 <kristianpaul> (no mark as read feature) nice trick :-)
2011-10-10 19:09 <kyak> but i really dont't download much. I just dont' miss what i'm looking for..
2011-10-10 19:19 <viric> kyak: I think that you need something made more specifically for the task
2011-10-10 19:20 <viric> kyak: I thought of having some kind of mark, other than 'read'... but as long as I'll not need it, it's fine for me. :)
2011-10-10 19:45 <zrafa> wpwrak: rodolfo found between all his old stuff almos forgotten a scope :) He will bring it to uni tomorrow
2011-10-10 20:02 <wpwrak> zrafa: whee ! did he tell you which brand/model it is ?
2011-10-10 21:40 <zrafa> wpwrak: nope, and i guess that it could be an old one :)
2011-10-10 21:46 <wpwrak> perhaps the one, his family, when then came to argentina before the war, remember their grandparents considering a precious family heirloom. you should feel honored that he would let you touch it :)
2011-10-10 22:21 <zrafa> wpwrak: ;-))
2011-10-10 22:26 <kristianpaul> lol
