i'm writing webgl program draws bunch of triangles screen. i'm using indirect addressing, this: gl.drawelements(gl.triangles, list.length, gl.unsigned_short, 0); is there way vertex shader know vertex of triangle processing? (among 3 vertices in order given list, i.e., first, second or last) you can use additional integer attribute in stride alongside vertex coordinates, texture coordinates, normal, etc. check id of vertex.

i spatial modelling of variable t (temperature). use commonly used in literature - perform regression (using variables altitude etc.) , spatially interpolate residuals using idw. r package gstat seems have option: interpolated <- idw(t ~ altitude, stations, grid, idp=6) spplot(interpolated["var1.pred"]) but in documentation of idw() write: function idw performs [...] . don't use predictors in formula. and actually, result looks if regression performed, without spatial interpolation of residuals. know can manually: m1 <- lm(t ~ altitude, data = data.frame(stations)) tres <- resid(m1) res.int <- idw(tres ~ 1, stations, grid, idp=6) tpred <- predict.lm(m1, grid) spplot(spatialgriddataframe(grid, data.frame(t = tpred + data.frame(res.int)['var1.pred']))) but have many drawbacks - model not in 1 object, cannot directly summary, check deviance, residuals , importantly, crossvalidation... have done manually. so, is there way how regr...

i'm sorry if explained in scipy.sparse documentation. when using scipy, function recommend using solve sparse positive definite linear system of equations? want use direct method, , want columns reordered preserve sparsity as possible in cholesky factorization of coefficient matrix. ideally i'd able experiment various options reordering. does direct solver sparse positive definite systems exist in scipy.sparse? scikit.sparse way go? scipy.sparse.linalg.spsolve clear enough, seems speed must pip install scikit-umfpack or else build umfpack , amd suitesparse then rebuild scipy source, [umfpack] umfpack_libs = ... in site.cfg . otherwise scipy.sparse.linalg defaults slower superlu. is scikit.sparse way go? compared what, criteria ? if c / c++ enough you, use suitesparse directly. tool depends on you're comfortable with, , on users: one, two, many. maybe better visualization project more faster spsolve. some pretty obvious pluses , m...

in midst of developing laravel 4 app, i've decided start making use of laravel's migration feature. question: should write migrations creating tables have in database? or write migrations future changes? there no complete right answer this. depends on lot of variables, style of development, how many people you're working , in kind of environment (single production db? multiple dev dbs?), requirements migrations are, etc. etc. if do decide write migrations entire db until point, you'll need make sure migrations can handle potential conflicts. making use of schema::has() , such verify tables exist prior attempting create them, , such. alternatively, can write migrations if db has clean slate, , enforce devs start empty db prior running migrations. has risks, careful. make sure have backups in case migration forgot , need modify it. so, tl;dr: using migrations entire structure part way through project bad thing? no. right application? entirely depen...

we have table in our database stores xml in 1 of columns. xml in exact same format out of set of 3 different xml formats received via web service responses. need information in table (and inside of xml field) frequently. poor use of xml datatype? my suggestion create seperate tables each different xml structure talking 3 growth rate of maybe 1 new table year. i suppose matter of preference, here reasons prefer not store data in xml field: writing queries against xml in tsql slow. might not bad small amount of data, you'll notice decent amount of data. sometimes there special logic needed work xml blob. if store xml directly in sql, find duplicating logic over. i've seen before @ job guy wrote xml field long gone , left wondering how work it. elements there, not, etc. similar (2), in opinion breaks purity of database. in same way lot of people advise against storing html in field, advise against storing raw xml. but despite these 3 points ... can work , t...
