i using slick 1, , have able apply filter in query lookup entities match condition in related table. this example using slick documentation shows trying (this contrived example close situation). here, want coffees provided suppliers on west coast. want coffee only, interested in navigating suppliers apply filter: val westcoast = seq("ca", "or", "wa") val implicitinnerjoin = { c <- coffees s <- suppliers if c.supid === s.id && s.state inset westcoast } yield c this works ok, duplicate coffees if there more 1 match in suppliers table. the obvious workaround in normal sql select distinct; however, cannot find way here. you in theory a: query.list.distinct after results returned; however, have implemented paging support, wouldn't want process results once come database. here paging support: query.drop(offset).take(limit).list so, in nutshell, need way specify select distinct in query goes out. anyone have idea...

i trying exclude category shortcode shows latest posts. have searched while solution cant seem different options work. this code, (unfortunately didn't write need edit it): function blogcuts_homepage_sc($atts, $content = null) { $blogh = ''; $last = ''; $counter = 1; $args = array( 'post_type' => 'post', 'order' => 'desc', 'posts_per_page' => 4 ); query_posts( $args ); if ( have_posts() ) : while ( have_posts() ) : the_post(); if ($counter == $args['posts_per_page']) { $last = ' last-column'; } $img_array = wp_get_attachment_image_src(get_post_thumbnail_id(), 'small'); $comments = get_comments_number(); $custom = get_post_custom(); $blogh.= '<article class="blog-excerpt'.$last.'">'; $blogh.= '<h3><a class="bg-transition" href="'...

recently, i've been working on noughts , crosses game, i've stumbled upon problem can't seem able fix. whenever type in first time, works , prints out board, however, point onward, stops checking , printing out board. while(inf){ string temp = input.next(); if(playerturn == 1){ if(amountp1 <= 3){ if(temp.equalsignorecase("00")){ if(board[0][0] == 0){ board[0][0] = 1; showboard(board); playerturn = 2; amountp1++; } else{ system.out.println("this space occupied!"); } } else if(temp.equalsignorecase("01")){ if(board[0][1] == 0){ board[0][1] = 1; showboard(board); play...

i have written code run several time-series rolling-regressions multiple securities. since number of securities more 10,000, , having more 200 rolling windows each security, runtime sequential set-up (using foreach %do%) 30min. i implement foreach %dopar% parallel computing instead, using "doparrallel" backend. changing %do% %dopar% in code doesn't trick. new parrallel computing method, , hope help. here foreach %do% code: sec = ncol(ret.zoo) num.factors = 2 rows = nrow(ret.zoo) - 60 + 1 beta.temp = matrix(nc = num.factors + 1, nr = sec*rows) gvkey.vec = matrix(nc = 1, nr = sec*rows) d = 1 foreach(i=1:sec) %do% { df = merge(ret.zoo[,i], data) names(df) <- c("return", names(data)) gvkey = substr(colnames(ret.zoo)[i],2,9) reg = function(z) { z.df = as.data.frame(z) ret = z.df[,which(names(z.df) == "return")] ret.no.na = ret[!is.na(ret)] if(length(ret.no.na) >= 30) { ...

so problem trying position sprite in middle of screen. how simple calculations made during runtime wrong. have come conclusion floating points being messy in java. so, code have right now, works: float posx = ((1280f / 2f) - 128f); float posy = ((720f / 2f) - 112.5f); splash.setscale(1.5f); splash.setposition((posx), (posy)); but if replace divisions above these variables: private float screencenterw = (1280.0f / 2f); private float screencenterh = (720.0f / 2f); private float splashcenterw = (225.0f / 2f); private float splashcenterh = (256.0f / 2f); things not seem work anymore. seems me first part of posx , posy calculations result in 0.0 , sprite ends in upper left corner, half-visible. why if replace different calculations these variables, stops working? edit: so clarify: this how want code like: private float screencenterw = (1280.0f / 2f); private float screencenterh = (720.0f / 2f); private float splashcenterw = (225.0f / 2f); private float splashcenterh ...

i need solve problem opposite this one . have qstring non-ascii symbols. example: schöne grüße how length of string in bytes utf8 case? should 15. have tried conversion bytearray , latin1 , ascii length same. you need use ::toutf8() , append qbytearray. can length using .size(). qstring s = "schöne grüße"; qbytearray bytes = s.toutf8(); int length = bytes.size(); //number of bytes http://harmattan-dev.nokia.com/docs/platform-api-reference/xml/daily-docs/libqt4/qbytearray.html#size

it highly appreciated if me find out went wrong in configuration. i wanted increase value of io.sort.mb , added property below in core-site.xml. io.sort.mb 350m the runtime information attaching below shows value of io.sort.mb, did not change rather default value io.sort.mb = 100 stayed. 13/08/15 16:43:34 info mapred.task: using resourcecalculatorplugin : org.apache.hadoop.util.linuxresourcecalculatorplugin@1e5e96c1 13/08/15 16:43:34 info mapred.maptask: numreducetasks: 1 13/08/15 16:43:34 info mapred.maptask: **io.sort.mb = 100** 13/08/15 16:43:34 info mapred.maptask: data buffer = 79691776/99614720 13/08/15 16:43:34 info mapred.maptask: record buffer = 262144/327680 13/08/15 16:43:34 info mapred.maptask: starting flush of map output 13/08/15 16:43:34 info mapred.maptask: finished spill 0 13/08/15 16:43:34 info mapred.task: task:attempt_local_0001_m_004609_0 done. , in process of commiting since not working, added property in mapred-site.xml s...
