<0> DaveHowe, you understand what a photodiode does, right?
<1> Liandrin: yeah.
<2> DaveHowe, it should be pretty simple. it depends on the light senstivity anyway
<2> sensitivity*
<0> DaveHowe, the voltage output from a photodiode varies depending on the amount of light falling on it
<2> a reverse biased photodiode for example would have different amoutns of current in it depending on light intensity..
<1> Liandrin: indeed. however, they are supplying current *into* the led and using it to emit light
<3> ffmpeg is a steaming pile of ****
<0> DaveHowe, right, so it supplies its own light source, and the voltage differential still contains the photodiode output
<1> all I can ***ume is that they are measuring voltage drop across it under load using a very sensitive digital voltmeter
<0> DaveHowe, er, the current differential, that is
<2> reality, you're right there. the code base is totally revamped every 3 months
<2> Liandrin, current dif..
<2> uh nm
<1> looking for a very very small difference due to additional reflected light from the hand making it back to the junction
<0> vIkSiT, I have problems with pairs ;)
<2> hehe
<0> DaveHowe, current
<0> DaveHowe, the amount of current consumed by the LED will change according to its photodiode nature
<0> DaveHowe, that's why it has to calibrate itself first, with nothing above it
<0> DaveHowe, the boxes at the baseline level represent the ordinary operating current of the LED
<0> DaveHowe, as he touches the LEDs or waves his hand above them, their current consumption appears to change
<4> hm... anyone happen to know the setting or command (if any) in xemacs that would format an entire .c file?
<2> cappicard, indent?
<0> DaveHowe, representing (operating current of LED) + (photodiode output value)
<1> Liandrin: given all the photons being emitted though, it must be pretty marginal - would need a very sensitive detector - probably an opamp to make the differential detectable
<2> ctrl _ the text, and M-X-indent-region
<0> DaveHowe, the video does show a large pile of equipment
<0> DaveHowe, and the photo shows lots of wires
<0> DaveHowe, maybe even a DSP too
<4> ah, I just found it too.
<4> *slaps himself*
<2> heh
<5> i have a error when i try to install glib... Error1:Leaving directory
<0> DaveHowe, it's not necessarily *trivial*, but as he shows, it's certainly *possible*
<2> i just go ahead and do an M-X and type whatever it is i;m trying to do
<5> how i solve that?
<2> more often than not, i get what i want!
<1> oh, its obviously possible. what I was saying was he didn't give any details on *how* he did it other than a bare ***ertion that a led was also a photodiode
<4> ah cool
<0> DaveHowe, right, the implication being you can work out how from the starting knowledge that LEDs act as photodiodes ;)
<4> hm... I wonder how many threads I can fire up to ping an entire subnet from C?
<0> DaveHowe, so, a photodiode's current varies depending on the amount of light, and an LED acts like a photodiode, so delta-I is what you want to measure
<1> Liandrin: either that or they are patenting it and they don't want circuit diagrams on the web yet :)
<0> DaveHowe, exactly how you measure delta-I isn't really important
<4> it seems that ping -b does not ping every active IP within a subnet
<0> DaveHowe, unless you want to build one, of course
<0> DaveHowe, then you need to know how to build something to measure delta-I ;)
<4> vIkSiT: heh seems that pinging a 4000-IP subnet will take forever if done consecutively (one ping per IP per second...)
<5> i have a error when i try to install glib... Error1:Leaving directory
<5> how i solve that?
<4> (for inserting an entry into the ARP table)
<6> bah, for some reason I'm unable to get MIDI to work here
<0> K_F, real or synthesized?
<6> doesn't really matter how you do it, I just can't play it
<7> k_f: what card? with my audigy I have to use sfxload to load a soundfont before playing
<2> cappicard, forever meaning just about an hour? :))
<6> hmm, thank you for the hint there libolt
<8> K_F: midi ****s anyway
<6> will try that
<6> Jostein: an aquaintance of mine plays keyboard, or is about to start anyways
<8> ah
<2> Jostein, no it doesn't - i've got some awesome midis of songs i've had since 1990 or so
<7> k_f: if you don't have hardware midi try out fluidsynth
<2> of course, recorded through synths
<2> Jostein, not many synths do mods..
<6> libolt: 00:0c.0 Multimedia audio controller: Creative Labs SB Live! EMU10k1 (rev 07)
<7> that'll work then
<6> libolt: 00:1f.5 Multimedia audio controller: Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) AC'97 Audio Controller (rev 01)
<6> those are the two cards I'm trying to get it working on
<6> I have fluidsynth installed
<9> clapping, your question doesn't make sense.
<7> you can get sfxload in the awesfx package on debian
<4> K_F: if you got your SB Live driver CD for Windows, then you can use sfxload to load up your soundfont and then use pmidi or your normal sequencer
<8> vIkSiT: true. but i dont have synth
<8> vIkSiT: to be honest I prefer MP3s :)
<2> haha
<4> I got a cool soundfont I found off the 'net. it's a 100Mb SF file
<6> cappicard: okay, thank you
<6> and you too libolt
<4> you're welcome.
<0> DaveHowe, I'm sure if you emailed Jeff he'd tell you :P
<7> cappicard: yeah with a little googling you can find quite af ew
<4> that's how I found this one
<4> this one sounds better than the default 2 and 4Mb ones that get installed in XP
<7> K_F: no problem
<7> cappicard: what's the name of the one you're using?
<4> it's called RealFont
<4> RealFont 2.1 to be exact
<7> yeah I have that one too
<0> K_F, look into a program called Timidity
<6> Liandrin: I will
<6> installing audacious now, it seem to use it
<10> Captain on the bridge!
<6> Liandrin: timidity plays it fine
<0> K_F, Timidity does its own wavetable synthesis and uses DSP output
<6> ok
<4> heya
<4> timidity can use sound fonts too
<6> No instrument mapped to drum set 0, program 28 - this instrument will not be heard
<6> hehe
<4> hmm... any other better ways of sniffing out active IPs other than ping?
<10> cappicard: arp table ?
<4> well, I am needing to add said IPs to the ARP table
<6> sound like a multicast ping
<4> arping seems to be doing unicast
<6> broadcast..
<4> could it do multicast?
<6> cappicard: ping -b 192.168.255.255 ?
<4> that doesn't work
<11> K_F: midi lives.. i wanted to ask you if you've ever successfully been able to use Rosegarden's notation editor without it crashing?
<10> window boxes don't respond to broadcasts.
<10> go figure
<6> Comet: can't say I've ever tried
<6> they probably haven't figured out how to implement it yet
<8> heh
<11> looks like a great program though.. once its not so buggy that is
<11> http://www.rosegardenmusic.com/
<11> most distros through it in their packages nowadays
<11> throw i mean
<6> Comet: it doesn't crash, but I don't get audio on my laptop with it
<11> ahh
<11> did you ever actually get your midi workin?
<4> hmm... in theory, if I ping 240.0.0.1, every multicast capable host should respond
<6> Comet: timidity plays it
<11> cool
<6> the laptop's soundcard probably doesn't have a synthesizer... or whatever
<6> Chip: SigmaTel STAC9750/51
<12> Well, I didn't make a 1.0 release today. But I got 0.99 of smp-encode out. I still need to work on the "other" encoder and get CBR for oggenc working as best as possible (oggenc can't do true CBR). Woot woot http://signal-lost.homeip.net/files/smp-encode_0.99.tar.bz2
<6> hehe
<6> next step: dist-enc ?
<8> safemode: I honestly dont see the use for CBR, unless you want to stream stuff
<12> next step is getting 1.0 out...basically cleaning up a bit. Then adding ripping.
<12> Jostein: hence the non-importance of the lack of the option
<12> i dont do **** in cbr.. but i thought it'd be nice to fully support oggenc and lame completely in the gui's options
<8> safemode: ah. I see
<12> at least the options in lame that the program can use... meta data **** isn't gonna be supported until 2.0 or so
<8> I -need- my automatic metadata support
<8> but I dont have a SMP system, so I can cope with any existing 100% automatic tool
<6> don't want to enter those 2000 names yourself, eh?
<12> I go 1.0 is a stable release for encoding lists of files. 1.5 has ripping support, so you can rip audio, and encode the tracks in parallel as they get ripped (faster than encoding on the fly).
<6> safemode: I use grip for it
<12> 1.75 is a bugfix and such release, to get everything stable for 2.0 which will add automatic meta data / filenaming
<12> that'll make smp-encode just about the fastest way to encode a cd or selection of files and all in my nice hand coded GTK+ ontop of c++ UI :) no better way to learn all the fun parts of UI coding.
