i have static datatable (with 80k records) in common.dll , common.dll referred 10 windows services. so, instead of having 10 copies of datatable in memory need have 1 copy , services pointing data source. approach possible? given services @ least using different appdomains, , quite possibly different processes, sharing same data between of them tricky. i suggest don't worry - unless each record pretty large, 80k records still going small. you could potentially have 11th service only 1 have data, , talk service other ones. that's introducing lot of complexity little benefit. one way of potentially saving memory use list<t> custom type, instead of datatable - may more efficient, , more pleasant use within code. doesn't if need datatable whatever you're doing it, try avoid that...

on php script, after parse string, need write data file (after create if doesn't exist). before write file, need exclusive lock avoid problems. code: foreach ($elements[0] $current) { $file_handler = fopen($my_folder .

"\n"); //release lock flock($file_handler, lock_un); fclose($file_handler); } return; now, seems not work. fopen create file, code seems go in loop inside while (file created, nothing write inside). what's wrong? you passing argument locking string instead of constant. try: $locked = flock($file_handler, lock_ex); notice missing double quotes around lock_ex

i tried display specific date database doesn't want work (the field empty). please me. query: var sejour = json.parse(select_sejourbyid(mydb, params.dc)); html: <div class="dx-field"> <div class="dx-field-label">date début</div> <div class="dx-field-value"> <div id="dated" data-bind="dxdatebox: { value: dated, format: 'date' }"></div> </div> </div> js: dated : ko.observable(new date(sejour.date_debut)),

we using jenkins perforce plugin reasonably in semi-continuous integration setup. "reasonably" in because our builds slow, not related jenkins , more our own code. one of main problems have if files have been deleted outside builds - e.g. if low on diskspace , "prunes" builds on build machines - p4 plugin cannot directly handle that. in mode run (without full-sync flag) assumes files sync'd on previous run still there. this covered under "quirks" on plugin page - https://wiki.jenkins-ci.org/display/jenkins/perforce+plugin - suggests "one time force sync" workspace normal. however, have couple of build machines each config bit of redundancy. in case, machine run next not same 1 had problem. makes tricky adding new machines pool. i wondered if had better solution. e.g. if key files missing (indicative of build being wiped) forced sync anyway? ok took me while twigged approach works @ least in our setup. pretty near top of jo...

i have 2 separate strings date , time formatted like: 14/04/2014 , 01:15 pm i convert these datetime formatted y-m-d h:i:s any idea how go this?? $date = datetime::createfromformat('d/m/y h:i a', '14/04/2014'.' '.'01:15 pm'); echo $date->format('y-m-d h:i:s'); demo

i have listfragment manages row(s) of 2 radio buttons per row, 1 button allowed checked, i've not been able manage radio button states properly. i'm pretty familiar listview's recycling of views. i've tried many different avenues no success, realize have keep states of radio buttons, list position , whether button has been initialized yet separately, can interface. it's , when set radio button states within adapter i've been wrestling with. i've tried has 1 condition or interfering other. setting radio button database initially, when there recycled view no radio button check , radiogroup.clearcheck() seems override when user chooses button. the state of radio buttons should controlled 2 sources; database source: 1) database column has value i'd set radio button initially, i'd show checked (.setchecked(true)) when user hasn't had interaction row yet, besides scrolling/no clicks. or database column 0 , no radio button should checked...

i deploy website using post-receive git hook. within hook use yui compressor minify js , css files: export temp=/var/www/example.com git_work_tree=/var/www/example.com git checkout master -f #minify mit yui (cd $temp/css && min style.css && rm style.css && mv style.min.css style.css) (cd $temp/addons/css && min bootstrap.css && rm bootstrap.css && mv bootstrap.min.css (cd $temp/js && min script.js && rm script.js && mv script.min.js script.js) (cd $temp/addons/js && min startup.js && rm startup.js && mv startup.min.js startup.js) now not specify exact files, search js , css files through folders in $temp , repeat minify procedure each time. could 1 me right loop , search-syntax case? thanks! just guess here, constructs this? find $temp -name \*.css -exec sh -c 'f="{}"; min "$f" && mv "${f%.css}.min.css" "$f"' \; ...

what best way render glass/ice materials on android devices no ray tracing? i have seen aplha+blending proper lighting, results looked "plastic". can better? you need proper reflection , refraction draw looking transparent materials. you need environment texture source of reflection/refraction. recommend render scene without transparent material make environmental source texture. cube-mapping recommended. visit here see how implement reflection , refraction. http://en.wikibooks.org/wiki/glsl_programming/unity/reflecting_surfaces http://en.wikibooks.org/wiki/glsl_programming/unity/curved_glass

i have curve of >1000 points fit differential equation in form of x'' = (a*x'' + b x' + c x + d), a,b,c,d constants. how proceed in doing using python 2.7? certainly intend have third derivative on right. group data in relatively small bins, possibly overlapping. each bin, compute cubic approximation of data. compute derivatives in center point of group. derivatives of groups have classical linear regression problem. if samples equally spaced, might try move problem frequency space via fft. sensible truncation of data might problem here. in frequency space, task reduces polynomial linear regression.

i using random forest classifier (in r) predict spatial distribution of multiple native plant communities using variety of environmental variables predictors. classification system hierarchical each successive level becoming more detailed in class description. example, have hierarchical classification system 2 levels , upper level consists of 2 classes: forest (f) , grassland (g). lets second level each forest , grassland class composed of 2 subclasses (f1,f2 , g1,g2). using forest class example, subclasses might conifer or deciduous forests. i know pretty basic far, here's challenge i've run into. i'd predict spatial distribution of these classes @ finest classification level there environmental variation acceptable accuracy. reduce variability can train multiple random forest models first model (model #1) operates @ uppermost level classifying observations either f or g. @ second level, subset data 2 groups based on f/g class , train 2 models (models #2 , #3) each c...

what i'd have c++ code open mplus (statistical program i've downloaded on computer) , run it. possible? you may able want std::system() calls like: std::system("program -e input_commands.txt"); // assuming accepts sort of command line args std::system("program < input_commands.txt"); // assuming responds stdin it depends on program if approach work.
