i performing image compression. the image i broken k code blocks {bi}. each block has fixed size mxn pixels. each block independently compressed. all compressed blocks {ci}, compressed sizes {pi}, stored in linear buffer b , of size k * m, m fixed size greater sizes pi. now, pack buffer b buffer c , , rid of empty space @ end of each compressed code block ci. so, need kernel will: for each block ci, find sum of pk k < i, (call offset_i) copy data each ci, b c , @ offset_i, of size pi any ideas on how appreciated!! here code snippet, (i suppose) stream compaction. contains tons of arithmetic, can parallelized desired measure. #include <time.h> #include <stdio.h> #include <stdlib.h> typedef struct block { int size; int buf[8]; } block; typedef struct blockpos { int t_size; //temporary size compaction int f_size; //actual size int pos; //position } blockpos; int main() { const int num_blocks = 16;

here's database notification system (it has been stripped down simplicity). when user deleted want related notification , useremail deleted constraint may cause cycles or multiple cascade paths error when try set relationship on delete cascade. unable create relationship 'fk_notification_targetuser'. introducing foreign key constraint 'fk_notification_targetuser' on table 'notification' may cause cycles or multiple cascade paths. specify on delete no action or on update no action, or modify other foreign key constraints. not create constraint or index. see previous errors. after doing research possible solutions are: add instead of delete trigger user table , manually delete child tables. redesign tables suggested here: foreign key constraint may cause cycles or multiple cascade paths? i'm not quite sure in case. do logical/soft delete. (recommended in comments) any recommendations should do? additional resources: implementing r

in java, how should create map<string,string> has unmodifiable keys, while keeping values modifiable. i'd hand map<string,string> through interface else add/change map values, not able change map keys. the background on higher level problem have list/set of variable names (with tree structure) (represented java string) i'd code on other side of java interface able populate aliases (also strings) each of variable names. i'd have multiple implementations of interface naming tree hierarchy can aliases different ways fit different situations. having interface implementation populate map<string,string> bunch of keys set-in-stone (and maybe containing defaults values) , allowing modify values (but not keys), seems best approach. i'm creating mapping between names , alias, map<> makes sense. back lower level problem. i'd code resemble: public class myclass { public interface imymapper { void build(

given example document in mongodb collection: {"_id": 100, "name": "user name", "sidefield": "some value"} and entity morphia: @entity() public class user { @id public long id; public string name; } is possible update mongodb document following example user object user user = new user(); user.id = 100; user.name = "new name"; so morphia not delete "sidefield" attribute? by default when use morphia's datastore.save(...) method, morphia replaces whole document under given _id new one, built entity, deleting way attributes not mapped entity. know can make "manual" updates of selected fields, that's not why added object mapper project's dependencies. finally, have dropped morphia , solved problem using mongodb java driver api 3.0.0 , jackson this: string updatejson = .... //i json string via rest api // here, if want validate update use json schema // or jackson (to

according laws of conditional probability, statement s1 && s2 will never true if s1 false. however, in angular, not alaways true. in html have angular expression: ng-if="file.nodes" file object has node property, , if does, array. angular expression "file.nodes" evaluates false if array exists empty (this problematic js evaluates empty arrays true if statements). however: ng-if="file.nodes && (file.nodes.length == 0 || true)" will evaluated true if array empty. in situation, angular seems not inconsistent js, (or laws of conditional probability). correct in believing bug? since seems egregious if is. some things know 1) in js empty array evaluates "true" 2) || evaluate true if either side of evaluates true 3) && requires both left , right side evaluate true evaluate true file.nodes = [] file.nodes && (file.nodes.length == 0 || true) // true because in js empty array evaluates true (l

what want do i have file contains sensitive datas don't want push content of file remote server. what did? to achieve this, made commit when file empty , pushed empty file server (github). , fill file sensitive datas , applied git update-index --skip-worktree path/to/file . didn't made commit. now i'm trying switch branch i'm getting error : error: local changes following files overwritten checkout: path/to/file please, commit changes or stash them before can switch branches. aborting why use skip-worktree instead of assume-unchanged ? i read few questions subject, , found borealid's answer . --assume-unchanged assumes developer shouldn’t change file. flag meant improving performance not-changing folders sdks. --skip-worktree useful when instruct git not touch specific file ever because developers should change it. example, if main repository upstream hosts production-ready configuration files , don’t want accidentally

imagine have list, defined below: test <- list(1:4,5,8,1,2:3,10) i somehow match elements of list if contain similar numbers. example match test[[1]] , test[[4]] because both contain 1. likewise, test[[1]] , test[[5]] match because both contain 2 , 3. after matching, construct unique id corresponds each match. example answer following list ans <- list(1,2,3,1,1,4) edit: the intuition behind answer if elements of list test share common match, receive same id. means though test[[4]] , test[[5]] don't match, fact each match test[[1]] means assigned same id. this toy example. in practice apply matching large list (>100,000k elements). in mind algorithm need efficient. thanks in advance! here's 1 way using data.table : require(data.table) # generate data.table data id = rep(seq_along(test), sapply(test, length)) dt = data.table(id, val = unlist(test)) # solution dt[, ans := id[1l], by=val][, ans := .grp, by=ans][, ans[1l], by=id]$

how can create "drop-down" window using delphi? everything beyond point research effort; , in no way related answer. research effort making proper drop-down requires lot of pieces work together. assume people don't difficult question, , rather asked 7 separate questions; each 1 addressing 1 tiny piece of problem. follows research effort solving deceptively simple problem. note defining characteristics of drop-down window: 1. drop-down extends outside it's "owner" window 2.
