kanzurevarious gloves, some with accelerometers http://worldinventions.blogspot.com/2008/09/top-5-diy-glove-keyboards.html00:00
kanzureacceleration sensing glove ("virtual keyboard") http://web.archive.org/web/20080621115011/http://www-bsac.eecs.berkeley.edu/archive/users/hollar-seth/fingeracc/fingeracc.html00:01
kanzurewhat's the sampling rate on an accelerometer?00:03
genehacker>1hz00:03
genehackerpretty fast00:03
genehackerdepends on the accelerometer00:03
kanzurei would be bragging the hell out about that, but i don't see any discussion on data entry rates in the papers on that last link00:04
kanzureew00:04
genehackerugh00:04
genehackerthis is bad00:04
genehackerhttp://en.wikipedia.org/wiki/Accelerometer00:04
kanzure"28 hand gestures are recognizable with acquisition times up to 1 character per second"00:04
kanzure(for that last link)00:05
genehacker>10 Hz00:05
genehackerI am disappoint00:05
kanzure1 character/sec is basically 1/12th the current standard00:05
kanzurebut this might have been because of some recognition algorithms they were implementing00:05
QuantumGstill, it's interesting from a "hey wearable, I'm pointing at something, locate it and tell me what it is" perspective00:05
genehackerI still like the idea of the smart dust keyboard00:06
genehackerwhere you apply smart dust accelerometers to the tips of your fingers and start typing00:07
genehackerhttp://www.sparkfun.com/commerce/product_info.php?products_id=24800:07
genehacker590 Hz00:07
kanzurei wonder if anyone else recognizes how absurdly slow these things are00:07
kanzurehttp://ilab.cs.ucsb.edu/projects/mathias/KolschKeyboards.pdf has a review of virtual keyboards on page 700:08
kanzurethe max cpm that they record is 25000:08
genehackernow that senseboard is neat from a neat perspective00:10
kanzureheh i liked this one, a wearable keyboard user for 8 years http://designfiles.org/papers/unsorted/Everyday%20Wearable%20Computer%20Use:%20A%20Case%20Study%20of%20an%20Expert%20User.pdf00:17
kanzurehe only uses emacs and a shell with it, plus a monocle HUD00:17

samrosekanzure moving that last question here15:12
samrose kanzure, it looks like there is one difference in tangiblebit and skdb and that is how data for packages is stored15:13
samrose I think you are storing in git, and tangiblebit is gearing towards storing in mysql is that correct?15:13
kanzureno it's my understanding that tangiblebit is using the same flat file format that we are, except with different conventions15:16
samrosekanzure I think you are right that this is what they were doing, but today we were talking about their plans to use mysql with django as db-connect15:19
samrosenot that is means anything in regards to what we were talking about privately15:20
samrosesomeone else was asking me this question15:20
kanzurei strongly doubt that smari is going to put flatfile packages under mysql ;)15:20
kanzurehis django stuff is for something else15:21
samroseno, I actually believe this is what we were talking about (see ChristianS answer to this question in #tangiblebit right now15:22
kanzureholy fuck15:23
kanzureO.o15:23
* kanzure wonders why christian isn't in here ever15:23
samrosethey believe there is an issue with scalability in using flatfiles (I conjecture)15:25
samroseI agree. I think using flatfiles and/or mysql (or any sql) are bad idea15:25
samrosebad ideas15:25
samroseI mean, they work, but there could be a better way15:26
samroseI talked with tangible bit today about the possibility of using Erlang/mnesia as data store15:26
samrosekey:value instead of SQL15:26
samroseyou can still do list comprehensions in Erlang15:27
samroseit scales really well, and is distributable inherently15:27
kanzurewhat's wrong with the key:value dictionaries in their current file format? (.tb)15:27
samrosenothing15:27
samrosethey could be stored in mnesia instead of MySQL, is that I think15:28
samroseor, there are many other key:value stores that could be used15:29
samroseif not mnesia...15:29
samroseanother possibility: http://code.google.com/p/redis/15:34
fennif you are going to get all fancy you should use RDF15:46
fennhttp://en.wikipedia.org/wiki/Triplestore15:47
Utopiahhttp://en.wikipedia.org/wiki/NoSQL15:48
fenni don't get it15:49
fennwhy would you jump right in for something whose only virtue is that it can handle 2PB of data?15:50
samrosethere's a data model that we are working on that would allow you to store as object/relationship, then would translate to RDF, graph, document, key:value, depending on what you ask it to return15:51
samrosehttp://code.google.com/p/knowledge-commons/source/browse/knowledge_commons.erl15:52
samrosethis is the most flexible thing we could think of. can store data model of anything once you know what "objects" and "relationships" are.15:54
fennwhy not just start in rdf?15:55
fenni guess i dont understand what you're trying to do15:55
samroseI am trying to design for interoperability. Instead of forcing people to use RDF, I want RDF to be once choice among many. 15:56
fennaren't you "forcing people" to use mnesia?15:57
samrosewe have made this data model in many other databases mnesia not required15:57

fenn"It is a plus if you have extensive Star Craft gaming experience."19:33
fennAll people have a "tact filter", which applies tact in one direction to everything that passes through it. Most "normal people" have the tact filter positioned to apply tact in the outgoing direction. Thus whatever normal people say gets the appropriate amount of tact applied to it before they say it. This is because when they were growing up, their parents continually drilled into their heads statements like, "If you can't say something nice, don20:32
fenn"Nerds," on the other hand, have their tact filter positioned to apply tact in the incoming direction. Thus, whatever anyone says to them gets the appropriate amount of tact added when they hear it. This is because when nerds were growing up, they continually got picked on, and their parents continually drilled into their heads statements like, "They're just saying those mean things because they're jealous. They don't really mean it."20:32

fennthis sufficiently explains the nerd<->non-nerd disconnect for me20:33
kanzurefenn: too much tact: "apologies you consider yourself a 'nerd'"20:46
QuantumGmeh, I still have troubles with empathy20:46
QuantumGI dunno if its related to being a nerd20:47
QuantumGit's simply that I care about myself so much more than I care about others.20:47
QuantumGwhy should I waste time thinking about your stupid little emotions?20:47
fennQuantumG: that's just you being an asshole, there's a difference :)20:52
QuantumGfor sure20:52
QuantumGbtw, have you ever considered the Diana Troi character on TNG?20:57
QuantumGI wonder what the thinking behind that was?   "Ya know, we're likely to have a lot of bit part actors on this show that can't really present emotions all that well, and our audience is mostly geeks who have trouble with empathy, so we should have a character that just says *completely obvious shit about emotions all the time*."20:58

fenn It would appear that we have reached the limits of what it is possible to achieve with computer technology, although one should be careful with such statements, as they tend to sound pretty silly in 5 years.23:48
