(it's possible criterion never fulfilled , $_record_number empty.) the portion of script looks following: go record/request/page [ last ] refresh window [] go record/request/page [ no dialog ; max ( $_record_number ; 1 ) ] when refresh window step isn't present, script doesn't work correctly. instead of bringing record top of list view, brings bottom. unfortunately, refresh window step causes window flicker script redraws layout. is there way duplicate end results of above steps without using refresh window , avoid screen redraw? failed techniques i've tried: using refresh object instead of refresh window targeting objects in both header , body using go related record relationship target record if you're using filemaker 13 or higher, can try refresh object ...

i've been trying regular expression work code while , wondering if knows better way. i've got big chunk of text parse , want split array based on lines. straightforward, right? using regex: var re:regexp = /\n/; arr = content.split(re); easy. want split on lines not have space after them. figured i'd use \s character match non-space character after \n. var re:regexp = /\n\s/; arr = content.split(re); however, removes first letter of every line i'm splitting (because it's matching letters). what's best way to: ignore spaces using caret (i tried /\n^\' '/ no luck)? not lose \s character when splitting string array? use lookahead in pattern (so \s symbol won't consumed split separator): var re:regexp = /\n(?=\s)/; arr = content.split(re);

i'm trying hang of lenskit (quite hard @ first). right i'm playing around hello-lenskit examples, working expected. however, i'd go beyond , when read documentation seems it's not date, e.g., http://lenskit.org/documentation/basics/configuration/ (many links, such 1 lenskitrecommenderenginefactory , itemitemratingpredictor lead page not found ) so, how did experts master lenskit? trial , error? mailing list? here? cheers!!

i started doing amp-camp 5 exercises . tried following 2 scenarios: scenario #1 val pagecounts = sc.textfile("data/pagecounts") pagecounts.checkpoint pagecounts.count scenario #2 val pagecounts = sc.textfile("data/pagecounts") pagecounts.count the total time show in spark shell application ui different both scenarios. scenario #1 took 0.5 seconds, while scenario #2 took 0.2 s in scenario #1, checkpoint command nothing, it's neither transformation nor action. it's saying once rdd materializes after action, go ahead , save disk. missing here? questions: i understand scenario #1 taking more time, because rdd check-pointed (written disk). there way can know time taken checkpoint, total time? spark shell application ui shows following - scheduler delay, task deserialization time, gc time, result serialization time, getting result time. but, doesn't show breakdown checkpointing. is there way access above metrics e.g. schedule...
