10:19 deshipu hello
10:19 adam789654123 hello
10:19 robotustra what's up?
10:19 adam789654123 programming
10:19 adam789654123 working on a new concept
10:19 robotustra programming what?
10:20 adam789654123 the general idea is to extend a data-structure to the hard drive
10:20 adam789654123 because I am dealing with so much information, it causes my program to crash
10:20 robotustra what do you do?
10:20 adam789654123 garden mostly
10:21 adam789654123 but I like to program also
10:21 robotustra he he
10:21 adam789654123 :-D
10:21 adam789654123 the problem i am working on is solving for algebraic formulas
10:22 robotustra symbolic calculations?
10:22 adam789654123 well... im converting the equations to formulas because its faster
10:23 adam789654123 i said that wrongn
10:23 adam789654123 well... im converting the equations to numbers because its faster
10:23 robotustra ok, numerical solutions
10:23 adam789654123 then I can go back to dealing with the equations
10:23 robotustra but of what?
10:23 robotustra ewhat do you solve?
10:23 adam789654123 ill give you an example
10:23 adam789654123 of what I am going for
10:24 adam789654123 given three equations
10:25 robotustra ok
10:25 robotustra write them
10:26 adam789654123 a^2, b^2, (a+b)^2
10:26 adam789654123 what is their relationship?
10:26 adam789654123 if they are equated to
10:26 adam789654123 q1, q2, q3
10:26 adam789654123 then the relationship could be written
10:26 adam789654123 (q1+q2-q3)^2 = 4q1q2
10:26 adam789654123 This is the kind of problem that I am coding for
10:26 adam789654123 if a^2 = q1, b^2 = q2, (a+b)^2 = q3
10:26 adam789654123 then (q1+q2-q3)^2 = 4q1q2
10:27 adam789654123 so its been very educational problem to work on thus far
10:28 adam789654123 ive come up with inovations, interesting ideas, avenues for future research, and perhaps, if I can get it to that point, a practical tool
10:28 adam789654123 and it all started out with theoretical considerations
10:29 adam789654123 now i am working on extending data-structures to the hard drive, as a sub-problem
10:29 adam789654123 in particular, my simple idea I call "big-stack"
10:29 robotustra I didn't got your idea yet
10:30 adam789654123 you dont understand about solving formulas? Or extending a stack like data structure to the hard drive?
10:30 robotustra I know what is stack
10:31 robotustra and I'm doing my own interpreter of forth now
10:31 adam789654123 heres an interesting problem, that I am working on
10:31 robotustra and I use stack as well
10:31 adam789654123 if you have a stack of random data allocated to 30 files
10:31 adam789654123 each piggy backed to the other
10:32 adam789654123 how do you efficiently sort the data?
10:32 adam789654123 Ive come up with a stack based solution that is pretty fast
10:32 adam789654123 that I am very happy with
10:32 robotustra you solve abstract tasks
10:32 adam789654123 yeah
10:32 adam789654123 you might say that
10:33 adam789654123 i am interested in abstraction
10:33 robotustra do new file system more efficient than existing and I'll tell you thanks
10:33 adam789654123 haha
10:33 adam789654123 im not working on that level
10:33 adam789654123 :-D
10:34 adam789654123 but if one is to follow the idea of extending data structures to the hard drive
10:34 adam789654123 who knows where it would lead
10:34 adam789654123 seems like a very interesting and exciting research feild
10:34 adam789654123 for example
10:35 adam789654123 extending data structure to the hard drive, to the internet, etc
10:35 adam789654123 anyway, its interesting to roll around in my head
10:36 robotustra all these problems were solved many times
10:36 robotustra you are too late
10:36 adam789654123 naaaa.... we can always improve on the wheel
10:36 robotustra do you know what is JSON?
10:36 adam789654123 and learn new things from it
10:37 robotustra xml?
10:37 adam789654123 i know of xml more than JSON
10:37 robotustra so Json is a mean to describe any structure you want
10:38 robotustra and map it to anywhere
10:38 adam789654123 thats interesting
10:38 adam789654123 ill have to look into that in the future
10:38 adam789654123 i think each generation, and each individual, has to learn old things anew
10:39 adam789654123 so these things have been solved before, but we need people that can think about them productively
10:39 adam789654123 im not too late
10:39 adam789654123 im in the mix
10:40 robotustra you are right to some extent
10:41 robotustra all math problems are far ahead of implementation and use
10:42 robotustra for at least 100 years ahead
10:42 adam789654123 and if you want to take the next step, you have to cilmb that big staircase yourself
10:43 robotustra sure, or go to university
10:43 adam789654123 note that university =/= education
10:43 adam789654123 ;-)
10:44 adam789654123 its certainly not an iff. situation
10:44 robotustra where did you study math?
10:44 adam789654123 at home
10:44 adam789654123 but in a sense, im only really beginning
10:45 adam789654123 i sense that I am just starting my journey into math
10:45 adam789654123 within the last year and a half
10:45 robotustra so, you state that you know almost nothing?
10:45 adam789654123 i guess so
10:46 robotustra so it's a mistake of all begginers, they think that they invented something new and original
10:46 adam789654123 its new an original for me
10:46 robotustra I passed that perioud when I was 7 years old
10:46 adam789654123 well.... maybe you ought to try something new
10:47 adam789654123 seems like youve been very narrowly focused your entire life
10:47 adam789654123 ;-)
10:48 robotustra ORLY?
10:48 robotustra ok, let's compare what you and me already did?
10:49 robotustra what did you do in you life, I mean your achivments
10:49 robotustra which are important for you and you proud of it?
10:50 adam789654123 Ive written a multi user online file system
10:50 adam789654123 with bells and wistles
10:50 adam789654123 including writting the server
10:50 robotustra you did a software only?
10:51 adam789654123 i wrote the software, and used it with a buddy of mine
10:52 adam789654123 I was working on extending it to be fast and multi-threaded
10:52 adam789654123 but i had trouble working with raw sockets
10:52 robotustra can you mount the internet ?
10:52 adam789654123 and i moved to other things
10:53 robotustra what material things yo did already?
10:53 adam789654123 its about intereracting with shared user space through the browser
10:53 adam789654123 including an extention to use the server as an independant server
10:53 adam789654123 for a users website
10:54 adam789654123 each user could use the server as their own server
10:54 adam789654123 by setting it up through the gui
10:54 adam789654123 so each user had a filesystem
10:55 adam789654123 and one user could brows the others filesystem, but could not edit it
10:55 adam789654123 only the user could edit their own file system
10:56 adam789654123 then this filesystem could be used as data for the user's server
10:56 robotustra it's already built in feature in windows and linux os
10:56 adam789654123 then this filesystem could be used as data for the users website*
10:56 robotustra any OS support this
10:56 adam789654123 and dont forget to mention me from now on
10:56 adam789654123 linux, windows, OS, and adam
10:57 adam789654123 made this
10:57 adam789654123 ;-)
10:57 adam789654123 it was a collaberation tool
10:57 adam789654123 a very cool one
10:57 adam789654123 and it was cross platform
10:57 adam789654123 because it worked through the browser
10:58 adam789654123 i gave up on the project when somebody couldnt get it to work in chrome
10:58 adam789654123 but i got it to work for internet explorer, firefox, safari, and others
10:59 adam789654123 and chrome would have required some kind of output adjustment
10:59 adam789654123 it couldnt parse my html correctly, apparently
10:59 adam789654123 when i say i gave up, I gave up before
10:59 adam789654123 because i started something else
11:00 adam789654123 i was working for a business research data
11:00 adam789654123 so i didnt have time for the server anymore
11:00 adam789654123 i was working for a business *parsing research data
11:01 adam789654123 and outputing it in various formats
11:01 adam789654123 for example, creating a program that took csv files and converted it to a turbolister db file
11:01 adam789654123 converted them*
11:01 adam789654123 so that research data could be uploaded directly to ebay
11:02 robotustra Google did it also in Google drive
11:02 adam789654123 cool.... just dont forget to mention me from now on... ;-)
11:02 adam789654123 and my solution was VERY general
11:02 robotustra so it's yet another poor implementation of what google already did
11:03 adam789654123 the utilities I came up with were so impresive that I want to restudy them
11:03 adam789654123 well...... base your opinion of a poor implementation on..... what?
11:03 robotustra do you work in google?
11:03 adam789654123 no
11:03 robotustra so why didi you decide that you didi better?
11:04 adam789654123 i didnt decide i did better
11:04 adam789654123 i wrote abstractions that where far beyond that
11:04 adam789654123 thats whats so exciting... TO ME
11:04 robotustra did you try google doc colaboration tools?
11:04 adam789654123 no
11:04 robotustra try it
11:04 adam789654123 ive tryed other collaberation tools though
11:04 adam789654123 and ive been very impressed
11:05 adam789654123 including coding collaberation tools
11:05 adam789654123 i dont want to get too wrapped up in google
11:05 adam789654123 or proprietary closed and hidden source programs
11:05 adam789654123 because its not what im into
11:06 robotustra ok
11:06 robotustra so show me your colaboration tool
11:06 adam789654123 i havent run it for along time
11:06 adam789654123 i would have to do things to it, to get it to work on my new system
11:07 adam789654123 hopefully i at least sound like i know what I am talking about enough to be convincing
11:07 adam789654123 i dont have any other evidence at this time
11:07 adam789654123 ;-)
11:08 robotustra if you colaboration tool is neat and work on linux I would use it
11:08 robotustra to develop robots
11:08 adam789654123 its definitely neet
11:08 adam789654123 but its very rickety, insofar as i developed it on one system
11:08 adam789654123 and it was very experimental
11:08 adam789654123 though this could be overcome with tlc
11:08 adam789654123 but i cant do everything
11:09 adam789654123 i love that i worked on that project
11:09 adam789654123 and if i resurect it, it will be on git-hub or some such
11:15 robotustra DOES ANYBODY ROBOTS IN HERE?
11:36 SpeedEvil https://www.youtube.com/watch?v=ygN8H3kI1qE
11:39 chris_99 haha
13:07 robotustra ping
13:07 robotustra rue, are you here?
13:07 robotustra garganautsauce?
13:46 robotustra rue_shop2: hi
14:19 AWSrobot Can someone recommend a good h-bridge for running two 5V dc motors, one on the left and one on the right? I'm finding the L293D IC to be useless because it drops voltage so much across - 22V input -> 0.2v output
14:20 Tom_itx 754410
14:21 AWSrobot it's a good chip with low loss?
14:22 Tom_itx it's an hbridge
14:22 Tom_itx dual
18:40 Mulvane The rotating drums that make up something like a old odometer...What the fuck is that called?
23:31 rue_shop3 hmm, I think I'm inadvertantly rebuilding opengl
23:31 rue_shop3 better make sure I do a better job...
