i have following code: intbuffer drawbuffers = utils.createintbuffer(2); int bfs[] = {gl30.gl_color_attachment0, gl30.gl_color_attachment1}; for(int = 0; < 2; i++) drawbuffers.put(bfs[i]); drawbuffers.flip(); gl20.gldrawbuffers(drawbuffers); if flip intbuffer int status = gl30.glcheckframebufferstatus(gl30.gl_framebuffer); don't equal gl_framebuffer_complete , if don't flip status right, black texture instead of desired texture, looked throught code on , on 2 days now, best bet part of code somehow wrong, rest seems ok. should intbuffer flipped before using in gldrawbuffers(intbuffer) ? yes, buffers should flipped before being passed lwjgl. the underlying gl api expects array functions take java buffer. size of array parameter in gl's c language bindings, hidden in java because lwjgl calculates difference between current position , end position. unless flip java.nio.buffer , sets "current" position beginning of buffer,

let's have 3 sheets (let's sheet1 , sheet2 , sheet3 ). sheet1 , sheet2 contain each sheet-level range named myrange . in sheet3 , if want access myrange sheet1 , able use ='sheet1'!myrange . but now, want sheet3 contain generic code , able refer either sheet1 or sheet2 . expect able achieve same thing using =indirect("'" & mysheetname & "'!myrange") however, error #ref when that. what do wrong ? how can work around ? if myrange consists of multi-row, multi-column range, make sure pressed ctrl-shift-enter when entered =indirect("'" & mysheetname & "'!myrange") . if forget use ctrl-shift-enter , #value error. however, stated have #ref . using code single-cell range, result looking for. way can #ref error using wrong sheet name. suspect problem. check sheet name , repost more detail if still doesn't work.

is possible "constrain" columns in 1 table "reference" columns views in information_schema in way (it needn't proper foreign key constraint, hence scare quotes)?-- need minimally-intrusive way of adding arbitrary metadata existing column data (e.g. add "comments" e.g. value shop.cheeses.name shop.cheeses.id = n ), , thought of defining table such: create table shop.metadata ( `table_schema` varchar(64) not null, `table_name` varchar(64) not null, `column_name` varchar(64) not null, `record_id` int(11) unsigned not null, `comments` text not null, /* show purpose of table */ primary key (`table_schema`, `table_name`, `column_name`, `record_id`), foreign key (`table_schema`, `table_name`, `column_name`) references information_schema.tables(`table_schema`, `table_name`, `column_name`) ); however, statement returns error 1215 (hy000): cannot add foreign key constraint , presumably because table_schema , table_name , co

i'm studying database mechanism , see there 2 mechanisms: table level locking , row level locking . don't see column level locking , when google, see no document tell except link: database locking . in link: a column level lock means columns within given row in given table locked. form of locking not commonly used because requires lot of resources enable , release locks @ level. also, there little support column level locking in database vendors. so, vendors support column level locking ? , can tell me more detail, why column level locking requires lot of resources row level locking . thanks :) a lock cannot, in , of itself, require anything. it's abstract verb acting on abstract noun. why should locking column cost more locking byte, or file, or door? wouldn't put lot of stock in link. the answer question lies in why locks exist -- protect -- , how dbmss engineered. one of primary jobs of dbms manage concurrency: give each use

i have complicated c++ scientific code, uses multiple libraries. imagine there 5 different types of libraries, linear solver, integration tool, etc. each library type there several different libraries same thing, have different internal implementation. in fact, every library wrapper class implemented, such libraries of same type have same interface. now, want give software user. want user able select libraries want use after code compiled. done means of input file. the problem coding in main program. when coding library selection, end using nested ifs, explicitly coding every possible combination of libraries, conditioned on parameters read file. wondering if there tidy way this. you can't implement templates dependent in input files, since template types resolved in compilation, not runtime. the tidy way polymorphism (also, elegant way ;d). define base class defines interface each implementation, create children classes each 1 it's own implementation, , th

i going through lectures of algorithms on coursera robert sedgewick.i bit confused when mr.robert pointed out 1 cannot use generics arrays not allowed. arraylist in collection framework uses arrays internally , generic datatypes allowed.i mean can following: arraylist<integer> list = new arraylist<integer>(); one hack pointed out this: public class fixedcapacitystack<item>{ private item[] s; private int n = 0; public fixedcapacitystack(int capacity) { s = (item[]) new object[capacity];} //this hack he mentioned ugly hack , must avoided , produces warning during compilation. my question is: 1.) how arraylist internally represent various generics types? 2.) if (assumed) use hack mentioned above why doesn't produce warning when compile program arraylist? 3.) there better way apart cast above? per source: 1 - arraylist stores items in object[] , , casts value when retrieving individual elements. there's @suppresswarnings(
