i have table of people, , want pull recent record of event, there may not one. so problem though i'm left joining make sure i'm getting record each person, i'm bringing people have events because i'm pulling max of date criteria. select * tbl_people left join tbl_events on tbl_people.people_uid = tbl_events.people_uid tbl_people.active = 1 , ( select max(event_date) tbl_events ) table people have following people_uid table events have following event_uid, people_uid, event_name, event_date like said, i'd output this: jen, had baby, 7/10/2015 shirley susan megan, had baby, 8/5/2014 etc. i hope makes sense. one way use correlated subquery in join checks there doesn't exists event same person later date: select * tbl_people p left join tbl_events e on p.people_uid = e.people_uid , not exists ( select 1 tbl_events e.people_uid = people_uid , event_date > e.event_date ) p.active

for enterprise rest api (php in case), bad practice include web socket server along rest api? pairing of 2 makes nice mix event dispatching services, i'm not sure if these 2 services different enough warrant separation? guess con can see @ moment, if rest api go down, web socket servers down, removes possibility of having fail-over connected clients, or degree. if you're looking robust way manage web sockets, check out http://faye.jcoglan.com/ - has libraries javascript, ruby, etc, , runs independently of other servers. if don't need kind of resilience, wouldn't worry mixing rest , web socket apis on same server.

i want use dancer2 eclipse? have done dynamic web projects on java directory structures generated eclipse.i searched google couldn't find documentation. if want these if new project should generate file structure dancer2. i can configure , run server eclipse itself. note: have epic plugin installed , working.i on linux. possible? you can run/debug dancer2 application in eclipse ide following steps: 1.create new perl project "file->new->perl project" 2.import source code "import->general->file system" new perl project. now have perl dancer2 project. there's thing need before run/debug project directly inside ecipse: copy or rename app.psgi app.pl, modify ->to_app ->dance. can right click app.pl , run "local perl" application. the psgi file running under plack command. introduced in dancer2. app.pl in dancer needs no modification.

i'm implementing dynamic kd-tree in array representation (storing nodes in std::vector) in breadth-first fashion. each i -th non-leaf node have left child @ (i<<1)+1 , right child @ (i<<1)+2 . support incremental insertion of points , collection of points. i'm facing problem determining required number of possible nodes incrementally preallocate space. i've found formula on web , seems wrong: n = min(m − 1, 2n − ½m − 1), where m smallest power of 2 greater or equal n, number of points. my implementation of formula following: size_t required(size_t n) { size_t m = nextpowerof2(n); return min(m - 1, (n<<1) - (m>>1) - 1); } function nextpowerof2 returns power of 2 largest or equal n any appreciated. each node of kd-tree divides space 2 spaces. hence, number of nodes in kd-tree depends on how perform division: 1) if divide them in midpoint of space (that is, if space x1 x2, divide space x3=(x1+x2)/2 line),

i want find max value of column. have following table structure: orderid | taskid | serialno 1 | 1 | 1 1 | 1 | 2 1 | 2 | 1 1 | 2 | 2 1 | 2 | 3 2 | 1 | 1 2 | 2 | 1 2 | 2 | 2 from above table want following result every orderid , taskid , display max value: serialno 2 3 1 2 by using max getting orderid , taskid well, not intended result. using sql server. how intended result? select orderid, taskid, max(serialno) mytable group orderid, taskid if want max(serialno) , can omit other 2 columns in select.

i'm talking follow button under users. can done access control without modifying views? hi alexander suraphel, in form view of our object @ bottom find following syntax : <div class="oe_chatter"> <field name="message_follower_ids" widget="mail_followers"/> <field name="message_ids" widget="mail_thread"/> </div> in : here message_follower_ids add follow feature can remove line, , remove feature object on view. thanks

i'm testing trie valgrind, , having "conditional jump or move depends on uninitialised value(s)" error after first symbol pass function create_trienode. i have struct: typedef struct trienode{ struct trienode **children; bool is_word; } trienode; func create_trienode: struct trienode *create_trienode(char c, struct trienode *parent){ struct trienode *node = malloc(sizeof(struct trienode)); node->children = malloc(alphabet_size*sizeof(struct trienode*)); node->is_word=false; return node; } and func create_tree struct trienode *create_tree(file *file) { struct trienode *root = create_trienode(' ', null); struct trienode *ptr = root; int character; int converted; int buffer; //this handles if file not end newline character = fgetc(file); buffer = fgetc(file); while(character != eof) { character = tolower(character); if (character == 10) // case newline { } else if(isalpha(character)) { con

consumesinglerequest <- function(api_key, url, columnnames, globalparam="", ...) consumesinglerequest <- function(api_key, url, columnnames, valueslist, globalparam="") i trying overload function this, takes in multiple lists in first function , combines them 1 list of lists. however, don't seem able skip passing in globalparam , pass in oly multiple lists in ... does know how that? i've heard s3 methods used that? know how? r doesn't support concept of overloading functions. supports function calls variable number of arguments. can declare function number of arguments, supply subset of when calling function. take vector function example: > vector function (mode = "logical", length = 0l) .internal(vector(mode, length)) <bytecode: 0x103b89070> <environment: namespace:base> it supports 2 parameters, can called none or subset(in case default values used) : > vector() logical(0) > vector(mode=&

i developing jni application. jninativeinterface_ * inside struct struct jnienv_ null, hence causing call jni (example : env->newstringutf(...) ) functions throw segmentation fault error. jnienv_ struct looks : struct jnienv_ { const struct jninativeinterface_ *functions; . . . i dont know how fix this, think java supposed fill when make call system.loadlibrary(...) . appreciate help. two possibilities: 1) c++ code called java native function: for example: jniexport void jnicall java_myjnative_dosomething(jnienv *env, jobject jo) { std::cout << "dosomething() : "; } the jnienv* pointer given java environment. 2) c++ code calls java code via jni: in case have setup javavm* , jnienv* pointer, following jni invocation logic. see example this article . a special case mentionned, if have invoked jnienv* work multiple threads on c++ side. every thread has attach jnienv* using: jnienv *env; // pointer na
