i have java service translates string key long id, through database lookup. i'm wrapping in guava cache reduce database queries. mapping key id doesn't change once it's set, can use long expire time existing keys. there timing issue (not in guava in app) might lookup id key before in database. not want cache "missing" mapping long. want cache though, avoid rush of queries same missing key. i read question: handle null value ... , , there cobbled solution 2 caches. have "missing keys" cache, let expire more , has no auto-load function. check cache first, , if find there know it's missing key. otherwise, try "real" cache, catching executionexception indicate "missing" , manually populate "missing keys" cache. feels quite awkward, part throw exception in load method when there's no mapping. wonder if there isn't more elegant way handle kind of problem. you might try based on refresh , implem...

why can't clone function in javascript assigning variable? e.g: var $ = document.getelementbyid; usage attempt: typeof $; //--> "function" $('nav'); //--> "typeerror: illegal invocation" think duplicate function, , still callable. can explain why not? when assigning document.getelementbyid variable lose this === document part you'd have when calling method of document . avoid this, use .bind() explicitly set this context function uses: var $ = document.getelementbyid.bind(document);

i tried blit 2 writeablebitmap. however, debugger prompted error message stating followings: the input writeablebitmap needs have pbgra32 pixel format. use bitmapfactory.converttopbgra32format method automatically convert input bitmapsource ?to right format accepted class. here code. rect crect =new (320,240); writeablebitmap _bitmap = new writeablebitmap(320, 240, 96, 96, pixelformats.bgr32, null); _bitmap.writepixels(new int32rect(0, 0, 320, 240), _image, 320*240, 0); //_image image stream _bitmap.blit(crect, _imageframe, crect); //_imageframe writeablebitmap actually _imageframe writeablebitmap canvas change content @ regular time. there more effective way blit writeablebitmap , canvas? can change line: writeablebitmap _bitmap = new writeablebitmap(320, 240, 96, 96, pixelformats.pbgra32, null); and similiar on _imageframe writeablebitmap

i've tried output data 2 linked tables , had @ examples find, i'm still not getting results. (note: i've tried exec_selectquery on either table , worked charm) so here's code $globals['typo3_db']->debugoutput = true; $res = $globals['typo3_db']->exec_select_mm_query( 'tx_pagecat_category.title', // $select_fields 'tx_pagecat_category', // $local_table 'pages_tx_pagecat_category_mm', // $mm_table 'pages', // $foreign_table '', //$where_clause '', // $groupby '', // $orderby '' // $limit ); while( $row = $globals['typo3_db']->sql_fetch_assoc($res) ) { $c= $row['tx_pagecat_category.title'].chr(10); } return $this->pi_wrapinbaseclass($c); i have absolutely no idea i'm doing wrong, debug-output not working? probably easiest way is: $globals['typo3_db']->store_lastbuiltquery = 1; // query here ...

i making complex tableview. should do it should have section headers title when scroll horizontal whole tableview should scroll horizontal you can not scroll in 1 section. here little screenshot. now question is, how can this? since not familiar uicollectionviews , try following: 1. create uiscrollview , set frame backgroundview.frame , add backgroundview 2. create uitableview . guess content dynamic, should possible calculate maximum width summing width of elements in each section / row. make tableview.size.width calculated width, add tableview scrollview . 3. set scrollview.contentsize.width calculated tableview.size.width . if understood question correctly, should have uitablview can scrolled horizontally , vertically. let me know if helped. edit: i created simple project doing described above. until now, datasource array of texts. should no big deal use array of e.g. custom uiviews add cell.contentviews . it seems work. feel free test i...

i have project supposed develop risc microprocessor . involves creating alu in behavioral model . there seems problems/errors/warnings while simulating design . of operations work except following : comparing 2 inputs : when numbers equal , 0 flag not getting set . ( unequal numbers working ) . warning: there 'u'|'x'|'w'|'z'|'-' in arithmetic operand, result 'x'(es). ( appears every 1 ps , presumably due wait statement in process ) i wish work std_logic_vector, though read messy . also, there problem when try use comparing commands ( update flags dont store difference in output register ) . how if commands executed in vhdl ?? executed @ same time ?? or line line ?? code below : library ieee; use ieee.std_logic_1164.all; use ieee.std_logic_arith.all; use ieee.std_logic_unsigned.all; entity alu port( input1 , input2: in std_logic_vector(7 downto 0 ) ; carryin : in std_logic ; zero,carryo...

i need following view layout in application. the green view viewport of ios application. on top (the blue ones) views should swipeable left , right 1 view (different content) visible @ time. views should snap in place if swipe. under this, there more views arranged horizontally (the orange ones). should snap in place (always centered 1 view in grey section) after swiping. here more 1 view visible @ time. there concepts pageviewcontroller , uiscrollview , uicollectionview , one. which 1 choose this? also idea add subviewcontrollers layout? controller each of scroll views? thanks in advance. for top go 3 uiviewcontroller's uiview (depending on complexity of objects). if simple things add 3 uiview's , and handle logic in same uiviewcontroller . either putting 3 inside uiscrollview (with pagingenabled ) or handling gestures both valid possibilities. botton uiviews (orange) uicollectionview (so handle memory you). uiscrollview botton, work, if...
