so now i'm bashing together a silly little fluid mechanics program; right now it's only going on a regular 2-D plane but it's interesting watching it evolve:



(red is x-velocity, blue is y-velocity at each point)

neat, I wish I studied more these physics instead of just observing the patterns in meteorological maps when I worked with these things

this week's project: same as last week, but now in THREETHREETHREEDEEDEEDEE


so far i've got lighting figured out; holy hell it takes a long time to light a sphere though. basically doing the vector math at each point on its surface to figure out the intensity (dot product of the normal vector with the unit vector pointing at the light source)


I know you like creating your own implementation of vectors and dot products and stuff and it's neat doing it once but consider using numpy arrays because it'll be a great skill to have in your sleeve.

numpy is kinda painful at first because the data structures aren't as straightforward to use as the built-ins but hey it's fortran-like numerics calculations speed at your reach :science:

still writing my vector function library



oh my god vectors suck so much

but at least when i've got all these basic functions, i can just call them when i'm doing 3d stuff and i don't have to think about angles and cosines and all that bullshit

maybe you should put all this vector stuff in a class or at least in a separate module idk

I wrote a buttbot for my native language last year and these days I decided to put it on twitter. I lost count of how many times it got suspended (I guess almost 20).

People seem to like it but I guess there are always 2 or 3 people in a group of hundreds that reports the account as spam.

I'm looking up the stream of recent tweets with the api that are in portuguese and that are not retweets. There are no other criteria, for some reason twitter returns a lot of tweets in spanish and sometimes polish (?). no idea why

duh

yeah this is pretty much what I do

also it isn't the REAL BIG TWITTER STREAM because access to this is limited for a few, this is what I use: https://dev.twitter.com/docs/api/1.1/get/statuses/sample

and hey look it was suspended again what a surprise

i also hooked up buttbot to twitter and it hasn't been reported/blocked/whatever for nearly 3 years now :shrug:

my program just runs every 5 minutes or so, grabs stuff from the stream sample api until it succeeds (usually the first tweet is fine, but it'll keep streaming until it is able to process one), then reposts it, then quits and cron starts it up again later

i used to stream 24/7 but it was total overkill for something as low-volume as that

i also used to follow back anyone who followed it and use that to get tweets (using the api equivalent of the home screen), unfortunately it resulted in following like a thousand spam bots, poo poo source material, and me hitting the upper limit of how many accounts you can be following at a time (it's around 1800)

I guess twitter changed the rules since then. with what you said in mind these days I tried manually following people who followed the account and it got suspended again but this time it's not coming back anymore :(

when we were talking about making this thing in python earlier people said beautifulsoup and I said lxml and my reason is that beautifulsoup is amazingly slow and lxml isn't much harder really

just wanted to get this out of my chest, if speed matters a bit don't use bs

it's going to be a buddy cop movie

spirit and opportunity, two veteran cops, have been partners for many years, until one day spirit is tragically killed in the line of duty

the hotshot rookie curiosity gets transferred in from another precinct and is partnered up with opportunity. opportunity is all by the book and everything, while curiosity is pretty trigger happy with his laser, etc. anyway they have to learn to work together so they can solve the case of the missing water


i'd still love help with the soundtrack though; that would be awesome

also the star background is actually celestia running on my projector which is set up underneath the table and aimed up at the wall

pretend this post starts with a space (thx radium) and this is a 190x190 costas array. it's mathematically the YOSPOS' UGLIEST POST.

(that video is kinda dumb I know)

seriously though it's just a fun combinatorial problem to play with (this is the idiot spare time projects thread after all), there's various papers using it to benchmark new techniques in combinatorial optimization. it's very similar to the 8 queens problem but much more elegant to state.
