i have written jsp , class takes file upload , stores locally on server. after saving file, uploaded file processed. required method calls should not called statically file storage. not this: storefile (file); mypostprocessingmanager pm = new mypostprocessingmanager(file); pm.createthumbs(); pm.dofoobarwiththefile(); this coupling tight. the methods should started on kind of "event". after uploading file event fired , informed appropriate classes carry out further processing. the whole fails on fact not know , how need register appropriate listener. in instances done in main class. can not since not have central starting point. i wrong track? maybe 1 of has idea? thanks , greetings, ben

i have javascript client , asp.net server. using simplemembership provider style authentification, login/register , roles working fine. problem is, once user logs in, have able check future server controller hits , determine whether permit or deny user use controller functions. first thought using sessions, once user logs in have created session store username (or id or whatever), , use later check whether role has sufficient rights. problem occurs when log in function hit, session created , credentials stored, function ends session ends (which means can't check future controller hits). question is, there way makes work way (lets somehow forcing session stay open until logout or timeout), or going wrong? thank in advance, , hope isn't 1 of "stupid" questions!

we setting nservicebus in distributor/worker model , wondering if worth us. in our initial test lab, have 2 clustered distributors , 1 worker (more workers in prod). wondering if effective leverage our high availability sql server storage , rebuild servers handle work instead of having dedicated distributors , workers. of our messages onto bus via simple .net web api service. install service on each box along endpoint dlls , have them talk sql server has more enough horsepower handle load. have load balancer available distribute messages handlers. what of drawbacks in taking approach vs distributor model? what has me concerned line david boike's book on nservicebus (great book btw) read...

mysql warning : primary key , index on same field in mysql . as in theory books these 2 terms used explain indices, in practice, when try make index on particular field primary key, mysql generates warning, although index created. could explain? a primary key implies index on set of columns make key, therefore second (separate) index is redundant : the primary key table represents column or set of columns use in vital queries. has associated index, fast query performance. so creating explicit index don't gain on contrary saddle database responsibility of having maintain 2 separate indexes.

i wanna access pi's gpio through java. yes know there pi4j, need use library called rcswitch-pi (on github), sends 433mhz signals (well believe can more thats need) the thing is, if use library plain c++, can control powerplugs , signals transferred. once use java via jni gpio pin never triggered. plugged in led check no current created. goes way point of script calls functions digitalwrite(this->ntransmitterpin, high); delaymicroseconds( this->npulselength); } but thats it. doesn't "digitalwrite" if not called java. yes performed sudo privileges that's not problem :-/ also, sort of out of curiousity: in code says "delaymicroseconds" , variable "npulselength" set 300. means each amplitude set 300ms before next 1 called. simple as: _ _ | |_| |_ for 1010 or something. anyways 433mhz pulse require each wave 60cm long or in other terms: 2.30947 nanoseconds * speed of light = 69.2361688 centimeters which mea...

to insert value, start using mask clear out 8-bits of pixel corresponding given color channel. example, in case of red, shift 8-bit mask of ones left 16 bits, invert (using ~ operator), , “and” (&) mask rgb value, clears out 8 bits of red , leaves other bits unchanged. next, shift parameter value (red, in case) left same number of bits (16, in case of red) , “or” (|) shifted value pixel value. int getred(){ red = (pixel>>16); red = ~pixel; red = pixel<<16 | pixel; return red; } what doing wrong according directions? the problem here seems fundamental problem in understanding how assignment works (in java ... , every imperative programming language!). example: red = (pixel>>16); red = ~pixel; that says: assign red value of pixel shifted 16 bits assign red value of pixel negated bitwise. clobbers value of red calculated in previous step. if want negate value calculated in step 1, need this: red = ~red;

i have alertscontroller has multiple alertcontroller children underneath it. when user clicks on alert set isselected flag true in alertcontroller alertview . have computed property in alertscontroller should return number of selected alerts. the alertscontroller , alertcontroller this: app.alertscontroller = ember.arraycontroller.extend({ itemcontroller: 'alert', //numselected doesn't update when isselected flag in alert changes numselected: function(){ return this.filterproperty('isselected', true).get('length'); }.property('@each.isselected') }); app.alertcontroller = ember.objectcontroller.extend({ isselected : false, }); i know isselected property in alertcontroller updating value numselected in alertscontroller computed once when page loads. i recreated issue in following fiddle: jsfiddle: http://jsfiddle.net/wlanf/8/ does know doing wrong here? thank assistance! you shou...

i'm doing project in c#. want catch data of scan code of keyboard. have used mapvirtualkey() function. function, keyboard have translated scan code ascii code, use function translate ascii scan code. want know how catch scan code of keyboard, before translate ascii code, mean when press key, make code. when release, break code. example, press key 'a' "1e" , release "9e" (makecode , breakcode of scan code set 1). all. here microsoft's information on raw input . here article on how using raw input c# handle multiple keyboards . (has code samples) this os level (winapi) function. seems need registering raw input , can perform standard/buffered read of raw input .

i new python, , wondering if there way can manage profiles staging or production ? best way other changing code every time ? there no "best" way pretty in programming (since "best" subjective idea, , every programmer , project different), since you've thrown on heroku tag, assume need way works on heroku. therefore, give the advice heroku gives you : a given codebase may have numerous deployments: production site, staging site, , number of local environments maintained each developer. open source app may have hundreds or thousands of deployments. although running same code, each of these deploys have environment-specific configurations. 1 example credentials external service, such amazon s3. developers may share 1 s3 account, while staging site , production sites each have own keys. the traditional approach handling such config vars put them under source - in properties file of sort. error-prone process, , complica...

will work? i'd test don't know how crash things half way though. $db = db::getdb(); try{ $db->begintransaction(); invoice::saveinvoice($info, $db); invoicedetails::savedetails($moreinfo, $db); $db->commit(); }catch(exception $e){ $db->rollback(); } and if work there bite me in butt besides doing causes implicit commit? the thing i'd fix exception handling. example catch (exception $e) { $db->rollback(); throw $e; } doing lets safely rollback transaction letting error bubble further in application. you wrap inner exception (which pdoexception ) 1 of choosing, eg $db->rollback(); throw new runtimeexception('error saving invoice details', 0, $e); to "crash things half way though" , throw exception within 1 of save* methods, eg throw new exception('ka-blam!');
