i wonder, happen if initialize object 0. for example : class vehicle { } main() { vehicle v =0; // or vehicle v; v=0; } assuming c++, code generate compilation error @ least 4 reasons: unlike k&r c, c++ not support functions implicit return values. main function returns int , , must explicitly declared such. the class keyword not capitalized, , language case-sensitive. might typo, compiler won't care. the declaration of vehicle class invalid. class declarations must end semicolon (after closing brace } ). the vehicle class not define constructor accepts integer (or implicitly convertible int ), cannot initialize new vehicle object 0 .

i using row_number() determine last row of query creating descending order , checking if on position 1. row | value ----+------- 3 | false 2 | false 1 | true do have idea how apply same technique determine last row of every group? the expected result should this: uid | row | value ----+-----+------- 1 | 3 | false 1 | 2 | false 1 | 1 | true 2 | 4 | false 2 | 3 | false 2 | 2 | false 2 | 1 | true 3 | 2 | false 3 | 1 | true or know better way detect last rows in postgresql? use partition by part of over() : select uid,something, row_number() on (partition uid order desc) row sometable partition by causes whatever window function you're using (such row_number() ) operate complete separately on each partition defined - row_number restarts number, max find maximum value rows within partition, etc.

there rule once heard when assigning storage size char , varchar instead of doing regular 4, 8, 16, 32 rule want use 3,7,15, 31. apparently has optimizing space in stored. know if there validity statement or there better way of assigning size char , varchar in postgresql? rule postgresql or keep in mind in of sql languages? you're mis-remembering applies @ lower level. strings in "c" language terminated zero-byte. so: "hello" traditionally take 6 bytes. of course, when assumed single character fit neatly single byte. not case more. the other (main) way store strings have length stored @ front, , have characters following. happens postgresql does, , believe has optimisation length doesn't take space short strings. there separate issues memory access cheaper/easier @ 2/4/8 byte boundaries (depending on age of machine) , memory allocation can more efficient in powers of 2 (1024, 2048, 4096 bytes). for postgresql (or of major scripting la

this question has answer here: random number generator generating 1 random number 9 answers i noticed, when using system.random , if next() called more 1 time in millisecond, returns same number (if has same parameters). assume random algorithm somehow concerns system's time, , dependent on that. i'd call next() many times within single millsecond - there way this, same random class? if not, i'd appreciate resources/other methods of solving this. this because when initialise new instance of random uses system clock seed. if twice, close enough together, you'll end using same seed , you'll same sequence of random numbers 2 instances. the solution alluded in comments already, instantiate 1 random object , repeatedly call next() on it, you'll new random number every time. var val1 = new random().next(); var val2 = new random().

i curious know algorithm r's mean function uses. there reference numerical properties of algorithm? i found following c code in summary.c:do_summary(): case realsxp: protect(ans = allocvector(realsxp, 1)); (i = 0; < n; i++) s += real(x)[i]; s /= n; if(r_finite((double)s)) { (i = 0; < n; i++) t += (real(x)[i] - s); s += t/n; } real(ans)[0] = s; break; it seems straight mean: for (i = 0; < n; i++) s += real(x)[i]; s /= n; then adds assume numerical correction seems mean difference mean of data: for (i = 0; < n; i++) t += (real(x)[i] - s); s += t/n; i haven't been able track algorithm down anywhere (mean not great search term). any appreciated. i'm not sure algorithm is, martin maechler mentioned updating method of west, 1979 in response pr#1228 , implemented brian ripley in r-2.3.0. couldn't find reference in source code or version control logs listed actual algorithm used. implemented in cov.c in revision 37389 , in summ

i making query using 3 table. quotes table has key called quote_id stored in quote_items table. there ever 1 instance of quote_id in quotes table in quote_items table may occur several times. want join 2 together, filter out instance quote_id occurs more once. select * quotes inner join quote_items on quotes.quote_id in (select distinct quote_id quote_items) inner join accounts on quotes.account_id = accounts.account_id , quotes.status = 0 primary_sales_id = 2 , quotes.quote_id = quote_items.quote_id order quotes.date_submitted desc you can ignore account_id part. line 3 should different, know, how go i'm not sure. if had quotes looking this quote_id | quote_name 1 | quote1 2 | qute2 and quote_items looking this quote_id | item_name 1 | boards 2 | nails 2 | blocks i should quote_id | quote_name | item_name 1 | quote1 | boards 2 | quote2 | nails you may use: select distinct quotes.quote_

imagine having label after created updates x amount of times / sec. text of label given format-specifier text (ala printf), , arguments format-specifier updated on redraw, because arguments format specifier pointers respective values. variant of sprintf work this? the code work this: /* client */ createlabel("value %f", &myfloatvalue); i haven't quite figured out way yet, have ideas? guess 1 parse format text, retrieve pointers (and types), , store them object in list, later reprint text , maybe delegate formatting objects themselves, passing them textbuffer.. hmmm btw, interface c, host c++. okay got "working" prototype, it's written in assembler. anyway demonstrates supposed use of api. can see portable way / have better idea implementation? it's pretty large i'm posting on pastebin: http://pastebin.com/h8zpwb4u so createlabel interface store format string, along addresses of variables you're wanting display within s

i've seen other similar questions , have tried implementing many solutions, to no avail far. specific questions involves little more complexity. need create table , join columns right side depending on criterion. seems simple enough, there few bumps encountering. the tables follows: adc_data_collection_header (pk)transaction_id | bemsid | device | timestamp | config_name adc_data_collection_apps (fk)config_name | num_data_elements | data_element1 | data_element2 | data_element3 | data_element4 adc_data_collection_data (fk)transaction_id | data_element_number | data i want final output like: transaction_id | device | config_name | data | data | data | data the "data" column filled in using table adc_data_collection_data. first instance of "data" "data" field in adc_data_collection_data data_element_number = 1. second instance of "data" "data" field in adc_data_collection_data data_element_number = 2... , on. the

the grails docs discourage use of composite primary keys, in this video (26:00 - 29:00) @burtbeckwith uses composite primary keys speaks performance benefits of mapping of join tables domain classes opposed using collections. raises several questions: why grails docs discourage use of composite primary keys? why burt using composite key? tried without 1 , seems work fine. didn't override hashcode or equals . burt using grails 1.3 when video made, performance concerns regarding collections still valid? can test myself turning on sql logging, haven't done yet. hibernate prefers simple primary key, if there's natural unique key (e.g. username in user table) since auto-incrementing long values simpler use foreign keys. supports other approaches of course, , gorm. the reason use composite pk in userrole table keep same implicitly created join table when use many-to-many in gorm. approach proposed intended same far database concerned, more performant,

how implement function users can upload images , drag , drop them in order present photos? i'm using ror framework. gems perhaps? one way put images in list , give each li data-attribute it's image id, like: <ul> <li data-image_id="1"><img src="/image1.png" /></li> <li data-image_id="2"><img src="/image2.png" /></li> </ul> then write nice javascript code (you use jquery plugins http://farhadi.ir/projects/html5sortable/ ) , use callbacks end of dragging. in callback write little code loops list, parses data-image_id values , sends data server further processing (by storing 'position' int in database example). ps. advice use position field desc new images, 0/null position, automatically end last 1 in row. client thrilled not having re-arrange images after added 4 new images ordered set.

i need build site cms interface , restful api (to use clientside framework, angularjs). refinerycms work me? also, have experience refinery, locomotivecms, or other rails-based cmss? prefer 1 on other? why? thanks! what mean cms interface? need allow users create pages, embed images/files, etc? i use refinery alot, , it. however, has no built in support restful api want, i'm assuming mean via json or something. you'd have override refinerycms-core engine , it's crud.rb file. refinery defines rest actions dynamically. i'm sure you'd have override other engines depending on functionality of core engines you're using. i'd try doing proof of concept first, on seeing how smoothly goes, decide continue or try cms framework. another lightweight alternative refinery comfortable mexican sofa . pretty easy add on full rails app maintain provide cms functionality. though didn't have override internal parts of it. i've never used l

what have tried achieve; counting number of rows in 2 tables (adding them together) grouping them country code in country column in table. output results number of rows , country e.g. gb => 200 views us => 500 views ch => 119 views mysql code have far; select count(id) totalclicks, country adverts_analytics_user_clicks advertid =:advertid group country this works well, need select same data table @ same time , combine count() values according country field. any appreciated! repeat first query against second table, such output coumns have same name , datatype. then union results together. finally sum total clicks country. select country, sum(totalclicks) totalclicks ( select count(id) totalclicks, country adverts_analytics_user_clicks advertid =:advertid group country union select count(id) totalclicks, country table 2 advertid =:advertid group country ) group country
