my general question is : inefficient/bad practice call preparedstatement.executebatch() if there's 1 query in batch? i'm writing generic method java helper library execute query. there's javabean called helperquery holds list of arrays javabean called queryparameter holds type (like string , blob , int , etc.) , value. queryparameter used fill helperquery 's preparedstatement . in many cases, there 1 array of queryparameter s. my specific question is : should handle things differently if there's 1 array of queryparameter s or ok handle things same regardless of how many queryparameter s there are? executebatch " super " method preparedstatement 's parent statement returns int[] indicates success/failure of executed queries , executequery returns resultset . therefore, idea have 2 totally different method calls developer can handle them differently. recommend: an executequery(helperquery helperquery) method return associate...

i'm using cherrypy , seems not behave nicely when comes retrieving data stored files on server. (i asked on , nobody replied, i'm on plan b, or c...) have stored class containing bunch of data structures (3 dictionaries , 2 lists of lists related) in mysql table, , amazingly, easier thought insert binary object (longblob). turned pickle file , inserted it. however, can't figure out how reconstitute pickle , rebuild class full of data now. database returns giant string looks pickle, how make string file-like object pickle.load(data) work? alternative solutions: how save class blob in database, or ideas on why can save pickle of class when go load later, class seems lost. in ssh / locally, works - when calling pickle.load(xxx) cherrypy errors. i'm plan d - if there's better way store collection of structured data fast retrieval without pickles or mysql blobs... you can create file-like in-memory object (c)stringio : >>> cstringio import s...

trying add commenting system pages. able scaffold list view for comments on each page. i thought use scaffold code , place partialview changing return value partialview(db.comments.tolist()); , viewresult actionresult . it breaks @ @for (item in model) {....} null reference exception error . so...any idea on how this? ex: commenting system anywhere. @model ienumerable<_2nditeration.models.comment> @{ viewbag.title = "messages"; } <h2>messages</h2> <p> @html.actionlink("create new", "create") </p> <table> <tr> <th> uname </th> <th> email </th> <th> subject </th> <th> referrer </th> <th> created </th> <th> comment </th> <th></th...

i've started going through randall hyde's "the art of assembly" start whetting palate. downloaded , installed hla 1.38 (which need 64-bit support) here , , wrote hello, world program described in both documentation listed there , in book above. program helloworld; #include ("stdlib.hhf"); begin helloworld; stdout.put("hello, world!", nl); end helloworld; when run hla helloworld.hla , following error message: helloworld.asm:66: error: ambiguous operand size or operands invalid 'push' the assembly line in question reads: pushd 0 ;/* no dynamic link. */ as green can assembly language, have no idea how make work. i'm assuming there's discrepancy between version of gas , hla 1.38. question remains: now? edit: tried compiling 'program', 'begin', , 'end' directives (removing possibility of being stdlib), , same result program nothing. i on 64-bit crunchbang linux. if want lea...

i looking building toolset using google apps script. problem far can tell in allows 1 level of organization. can create library called stopwatch , call methods stopwatch.start() , stopwatch.stop() pretty cool. what had in mind though more utils.stopwatch().start() , utils.timer.start() etc. think it's possible in javascript, in order keep breaking apps script autocomplete function needs added in format. below example example of doing wrong (gives error) perhaps saves time. it's based on this article. /** * stopwatch object. * @return {object} stopwatch methods */ function stopwatch() { var current; /** * stop stopwatch. * @param {time} time in miliseconds */ function timeinseconds_(time) { return time/1000; } return { /** * start stopwatch. */ start: function() { var time = new date().gettime(); current = timeinseconds_(time); }, /** * stop stopwatch. * @return {decima...

i have found digital persona finger fx open source project allows me supply finger print images (bitmap) , saves fingerprint minutiae data in iso/iec 19794-2:2005 format. https://github.com/fingerjetfxose/fingerjetfxose.git how compare 2 such iso/iec 19794-2:2005 templates? can suggest sample source code or article? sourceafis has partial implementation of iso/iec 19794-2 , comes examples in .net , java (experimental).

the search section in site www.anahatainternational.org displays correctly across ff, chrome, , safari. in safari mobile displays in middle of page. #search_section { position: absolute; right: 490px; top: 10px; z-index: 5; } thanks. i suggest making few changes layout of page make #search_section relative header. i have create skeletal structure it. http://jsfiddle.net/aacuy/ also remove left, top , position:absolute properties. there many classes in site me make changes using firebug , show result.
