i understand in sql server guids unique, , likelihood of collision remote, yet @ same time must win lottery feel makes sense prepare possibility. which faster/better practice using technique assign new guid directly inserting row , checking error (@@error <> 0) , repeating until don't error [which suppose in theory @ worst once...] or using approach this declare @myguid uniqueidentifier select @myguid = newid() if exists(select * tablename userid=@myguid) and looping on till find 1 not in use. i 2nd approach because can have guid use later on in stored procedure i'm leaning towards one. to answer question , not debate merit of question/perceived problem. the first implementation 1 want use 2 reasons: running check exists before doing insert every single record dealing in end result in more resources being dedicated extremely unlikely happen.

do need put serialversionuid on ancestors of serializable class? or on serializable class itself? you not need put serialversionuid @ all. java automatically determine appropriate serial id classes based on fields, methods, etc. the appropriate time have serialversionuids when storing objects file , need load them later, after have changed code. or, if transferring data across wire between components using different versions of library. 90% of time people need serialization, real-time, , library version matching on both sides guaranteed. in these cases, not need set serialversionuid, , can cause problems, if have 2 library versions incompatible have not changed sid. start getting weird errors since java thinks they're serially compatible, when actually, they're not. look @ these questions well: is there reason use real serialversionuid? why generate long serialversionuid instead of simple 1l? what serialversionuid , why should use it? edit add:...

in software need split string words. have more 19,000,000 documents more 30 words each. which of following 2 ways best way (in terms of performance)? stringtokenizer stokenize = new stringtokenizer(s," "); while (stokenize.hasmoretokens()) { or string[] splits = s.split(" "); for(int =0; < splits.length; i++) if data in database need parse string of words, suggest using indexof repeatedly. many times faster either solution. however, getting data database still more expensive. stringbuilder sb = new stringbuilder(); (int = 100000; < 100000 + 60; i++) sb.append(i).append(' '); string sample = sb.tostring(); int runs = 100000; (int = 0; < 5; i++) { { long start = system.nanotime(); (int r = 0; r < runs; r++) { stringtokenizer st = new stringtokenizer(sample); list<string> list = new arraylist<string>(); while (st.hasmoretokens()) list.a...

i have driver script manages job string can run jobs in parallel or sequentially based on dependency graph. example: job predecessors null b c d b e d, c f e the driver starts in background , waits complete suspending itselfusing bash built-in suspend . on completion, job sends sigcont driver start b , c in background , suspend again, , on. the driver has set -m job control enabled. this works fine when driver started in background. however, when driver invoked in foreground, first call suspend works fine . second call seems turn ' exit ' reports " there stopped jobs " , does not exit . third call suspend turns ' exit ' , kills driver , children [as should considering second converted call ' exit ']. and question: is expected behavior? if so, why , how work around it? thanks. code fragments below: driver: step...

i've made website using flask , have no problems getting things work on built-in development server. i've been able things running on production server under mod_wgsi. however, host static media static/cgi/php-5.2 application , can't flask 'see' without manually changing urls in html files. the problem seems basic flask setup expects static files within flask application. see here details. essentially, think need change url of 'static' portion of following 1 liner: <link rel="stylesheet" href="{{url_for('static', filename='css/print.css')}}" type="text/css" media="print"/> it looks can change in init .py, instructions here , defining static_path follows doesn't seem work. app = flask(__name__, static_path = '/web_media') to clear, if manually define url this: <link rel="stylesheet" href="/web_media/css/print.css" type="text/css" med...

i have piece of code generates quite large lists in each iteration. save memory want write each list binary file in each iteration after list has been generated. have tried text files(even setting parameter "wb" in linux). "wb" seems not have effect file written in binary or text format. moreover, written file huge , don't want this. sure if can write these lists in binary format file smaller. thanks since mentioned need compressibility, i'd suggest using pickle gzip module compress output. can write , read lists 1 @ time, here's example of how: import gzip, pickle output = gzip.open('pickled.gz', 'wb', compresslevel=9) x in range(10): output.write(pickle.dumps(range(10)) + '\n\n') output.close() and use generator yield lists 1 @ time: def unpickler(input): partial = [] line in input: partial.append(line) if line == '\n': obj = ''.join(partial) ...

i'm trying bind width property of canvas width property of shape instance. shape width should updated when canvas width gets new value i want in code, without xaml, because create these elements on runtime. i tried this, didnt work (the code inside of canvas): binding binding = new binding(); binding.mode = bindingmode.onetime; binding.source = this; binding.path = new propertypath("width"); shape.setbinding(frameworkelement.widthproperty, binding); thanks lot help! ksman onetime looks wrong. think want use oneway or twoway . check the bindingmodes edit since oneway , actualwidth didn't fix problem, should recommend use tool debugging bindings. use snoop because free, there others. debugging wpf without tool can painful.

i have little bit of conundrum. i'm developing wysiwyg editor plugin jquery web application. 1 of features inserting inline image tooltip based on images user has uploaded. example: hello there name [i="profile_pic.png"]a. username[/i] the part i'm having issue is, when defining images available user, whether should insert php array directly javascript so: var available_images = "<?=json_encode($user->profile->images)?>"; or go ajax returns encoded array of image sources? think inline php makes more sense since removes need unnecessary ajax call didn't think inserting inline php javascript terribly form? any suggestions? there's nothing wrong inserting data collected php js, how else js data? reason should consider ajax call be, if users upload new images while editing . mean information needs updated, make ajax call more appealing static json on page load.
