Printing Specific Rows in R - hi guys working big info frame records employee time card info specific months. want print out entire row of employees record maximum of 3 zeros in 3 different months. believe need utilize apply function: apply(employee, 1, ...) employee name of info frame, 1 allows iterate on each row, unsure how select have 3 or fewer zeros in row. appreciate help! you utilize rowsums() . here's illustration false data. > d <- data.frame(x1 = c(0, 1, 0, 0), x2 = c(0, 2, 2, 0), x3 = c(0, 2, 0, 0), x4 = c(3, 0, 0, 0)) > d # x1 x2 x3 x4 # 1 0 0 0 3 # 2 1 2 2 0 # 3 0 2 0 0 # 4 0 0 0 0 the can subset rows logical value of x == 0 sums 3 or less: > d[rowsums(d == 0, na.rm = true) <= 3, ] # x1 x2 x3 x4 # 1 0 0 0 3 # 2 1 2 2 0 # 3 0 2 0 0 r

php - Remove nth element from redis's list in thread safe way - in cron job, wish remove nth element redis's list, in thread safe way during iteration. is possible? may know how can so? i'm looking thread safe way. there author process, perform write operation same list time-to-time. while (true) { // elements "mylist" list. $list = $redis->lrange("mylist", 0, -1); // iterate through "mylist" list. ($n = 0; $n < count($list); ++$n) { if ($list[$n] == "dummy") { // wish remove nth element (with "dummy" value) "mylist" // in thread safe fashion. how? } } } thread safe of import such next situation won't happen cron job find out "dummy" element 5th element, , prepare remove it. writer process inserting additional element head of list, pushes "dummy" element 6th position. cron job removed 5th element list, n...

java - What is wrong with my normal calculations? - i attempted utilize algorithm described @ opengl - how calculate normals in terrain height grid?. popped in vertex shader , using perlin noise functions test it, , worked charm, when ported java, didn't work well. float nx = 0; float ny = 0; float nz = 0; vector3 p = new vector3(vpx,vpy,vpz); vector3 off = new vector3(1,1,0); float hl = trygetheight(_mempoints2,p.x - off.x,p.z - off.z); float hr = trygetheight(_mempoints2,p.x + off.x,p.z + off.z); float hd = trygetheight(_mempoints2,p.x - off.z,p.z - off.y); float hu = trygetheight(_mempoints2,p.x + off.z,p.z + off.y); nx = hl - hr; ny = hd - hu; nz = 2.0f; vector3 v = new vector3(nx,ny,nz); v = v.nor(); nx = v.x; ny = v.y; nz = v.z; the results algorithm in vertex shader: the results algorithm in buffer setup: (sorry blur, testing depth of field stuff when snapped these.) the results algorithm in vertex shader: normals should not calculated in sha...
