we have legacy coldfusion application using 150 client variables manage session state. client variables centrally stored in sql server database within 6 application server clustered environment using round-robin load balancer. the problem when code updates client variable new value, old value still being used , displayed though new value updated appropriately in cdata table. happens intermittently in average of 1 out of 1000 updates being made client variable using cfset tag. race conditions , caching issues possible explanations. “suspect” old value still being cached on 1 of 6 application servers. adobe's documentation states client variables cached memory not go further details. 1) has experienced issue , found resolution? 2) implications of moving sticky session while keep using client variables? i think first take closely @ database commits. client vars retrieved @ "beginning" of request , updated @ "end" of request changes. consider

i try access open data web service gives me traffic infos. documentation says requests have get , need contain accept: application/json , content-type: application/json . don't understand why need content-type ok: i tried retrieve data accept: header i'm getting 415 unsupported media type . trying way (but i'm not sure if setting both headers correctly): string entity = clientbuilder.newclient().target(livedatauri) .path(livedatapath) .request(mediatype.application_json) .accept(mediatype.application_json) .get(string.class); as see using jersey 2.2 , i'm still getting 415 unsupported media type . edit so got work don't understand why. isn't accept(mediatype.application_json) , header("content-type","application/json") same? string responseentity = clientbuilder.newclient() .target(livedatauri) .path(livedatapath) .request(mediatype.application_json) .header("content-type", "

i have model laps, belongs :car so each car has many laps, need query pull in top 10 fastest laps, pull in fastest lap per each car. in other words, not want 1 car allowed have 5 of top 10 fastest laps in list. each lap has :car_id field. want group on column, , pull out lap min(lap.time) row grouping. (aka fastest lap time unique :car_id). so postgres, best approach this? can order laps first, group, , pull first group. or grouping not keep sort order? here schema lap model: create_table "laps", force: true |t| t.decimal "time" t.string "video_url" t.integer "car_id" t.datetime "created_at" t.datetime "updated_at" t.integer "user_id" t.boolean "approved" end do have use 2 combined queries this? i can unique car id's lap doing this: select('distinct on (car_id) *') but, need order laps gets min(lap.time) per car_id. when throw on order

at moment working on kernel module of ccn-lite ( http://www.ccn-lite.net/ ). need security functionality (sha1 , public/private key authentificaton). user-space use openssl library, cannot use library in kernel module. it hard pick functions out of openssl , add them kernel module, because of them have dependencies libc. is there any security function in linux kernel, use? edit: can compute hash function of data received on ethernet: struct scatterlist sg[1]; struct crypto_hash *tfm; struct hash_desc desc; tfm = crypto_alloc_hash("sha1", 0, crypto_alg_async); desc.tfm = tfm; desc.flags = 0; crypto_hash_init(&desc); sg_init_table(sg, array_size(sg)); sg_set_buf(&sg[0], input, length); crypto_hash_digest(&desc, sg, length, md); crypto_free_hash(tfm); and want verify signature field of data using function digsig_verify. verified = digsig_verify(keyring, sig, sig_len, md, md_len); as far can see, second parameter signature, third len of signatu

in iphone application, i'm using subclass of afhttpclient access rest web service. want requests handled 1 instance of api client use singleton pattern. this works fine when service running on once url. can use constant value set url. now, in final version of application, each app talk service installed in corporate network. so getting service url remote configuration. singleton pattern still choice here? how supposed parameterise if url change during runtime of app ? cheers #import "fooapiclient.h" #import "afjsonrequestoperation.h" static nsstring * const kfooapibaseurlstring = @"http://192.168.0.1"; @implementation fooapiclient + (instancetype)sharedclient { static fooapiclient *_sharedclient = nil; static dispatch_once_t oncetoken; dispatch_once(&oncetoken, ^{ _sharedclient = [[self alloc] initwithbaseurl:[nsurl urlwithstring:kfooapibaseurlstring]]; }); return _sharedclient; } - (id)initwithbaseurl

i know may common question, have never found answer (and maybe has not knowing how search google correctly, if can point me reference, remove question). why doubles work how in terms of representing right side of decimal inverse power of 2, , left side of decimal power of 2? know allows large numbers represented, there other advantages? .net framework has decimal data structure available, seems more logical use becuase how represent numbers in human notation. really, question why doubles created way instead of creating decimal instead (which seems far less common). your confusion seems unfounded. right side of decimal point always represented in inverse power of base , left side always represented power of base. true base 10 , base 2 well. binary floating point numbers store exponent controls decimal point on mantissa. as why exist: binary floating point notation has 2 convenient properties: it relatively fast, because uses binary arithmetic it can represent e

let m matrix: m = rand(1000, 2000); consider following code example: a = zeros(size(m)); row = 1:1000 col = 1:2000 a(row, col) = m(row,col)*(row + col); end end how compute matrix a without for loops? there arrayfun function, don't know how index of current element: a = arrayfun(@(x)(x*(index(1) + index(2))), m); %// how index??? perhaps there other solutions (and without loops)? you can simple follows matrix represent row+col , multiply m m = rand(1000, 2000); rowpluscol = bsxfun(@plus,(1:size(m,1)).',1:size(m,2)); = m.*rowpluscol; from experience bsxfun extremely powerful function , can save run time, , perfect example of that.

i customize touch-based functionality of windows 8 metro app such in flip view, 1 can not swipe left right 1 finger 2 fingers while keeping zoom functionality (currently, zooming enabled, 2 fingers causes image shrink or grow in size rather go next or previous item). is, of code controlling touch behavior seems abstracted framework; there way can go accomplishing fine-tuning? i can't reproduce entire app in machine can advice go through gestures in windows 8. add event swipe gesture , if require(if id not zoomed before swiping) change selected index of flip view accordingly. gestures in windows store app note : in worst case if swipe gestures takes zoom, please debug , see if can recognize right left gesture or left right , change flip view selected index

i trying this: {{input value=email type="text" data-type="email"}} in order use parsley.js validate inputs. (i know email can use type="email") example. but seeing data-type="email" not showing in generated html. is there way can add html data- attribute handlebars tag? there different approaches can it: approach 1 you can reopen ember.textfield , define additional attributebindings , like: ember.textfield.reopen({ attributebindings: ['data-type'] }); now work: {{input value=email type="text" data-type="email"}} working example. approach 2 define own custom input field extending ember's ember.textfield app.mytextfield = ember.textfield.extend({ attributebindings: ['data-type'] }); and use this: {{view app.mytextfield value=email type="text" data-type="email"}} working example. hope helps.

i want distinguish phones ~5 inch , higher displays 4 inch 480x800 in res/values folder how can differentiate ~5 inch displays? should use trick, should got instead of xxx? values-swxxxdp? especially trying differentiate galaxy s 3 , galaxy s 4 others. should consider? s3: dpi: 306 res: 1280x720 screen: 4.8" 720 / (306/160) = 720 / 1.9125 = 376.47 dp s4: dpi: 441 res: 1920x1080 screen: 5.0" 1080 / (441/160) = 1080 / 2.75625 = 391.8367 dp so there small difference between s3 , s4. if want distinguish layouts these devices, use sw376dp s3 , sw390dp s4 . make note other 5" phones different.

i somehow stuck in logical thinking. i going compare date 2 states: summer semester (beginns on 16.04 - ends on 14.10) winter semester (beginns on 15.10 - ends on 15.04) all including vacations how check semester month/day in? current_month = datetime.datetime.now().month current_year = datetime.datetime.now().year current_day = datetime.datetime.now().day if current_month>=10 , current_day>=15: #winter semester but somehow doing chaos. there python lib date comparison problem? you generate summer dates: current = datetime.date.today() summer = current.replace(month=4, day=16), current.replace(month=10, day=14) if summer[0] <= current <= summer[1]: # summer semester else: # winter semester this use datetime.date() object instead of datetime.datetime() , time portion irrelevant here. date.replace() calls make sure reuse current year. this assumes, of course, summer semester starts , ends on same dates each year. demo: >

i'd launch default camera, want act started launcher (i.e. resulting picture should stored camera app user's gallery, rather being returned app). if use intent cameraintent = new intent(android.provider.mediastore.action_image_capture); , camera app uses "ok? retry?"-ui , doesn't save picture. i'd rather not use "direct" com.android.camera intent, because lot of devices use custom camera apps. i've seen stock gallery3d-app uses alias implementing com.android.camera/.camera , i'm not sure every pre-loaded manufacturer camera app this. i've implemented this: intent = new intent(android.provider.mediastore.action_image_capture); try { packagemanager pm = mcontext.getpackagemanager(); final resolveinfo minfo = pm.resolveactivity(i, 0); intent intent = new intent(); intent.setcomponent(new componentname(minfo.activityinfo.packagename, minfo.activityinfo.name));

i calling "queue" method after_create callback trigger sidekiq process on model instance after created. however, first time sidekiq worker picks job, record hasn't been committed yet. i know there after_commit record, want object queued when created, not when updated. how can accomplish without hackery involving date-checking, etc.? you set flag in before_create callback before_create :set_new_flag after_commit :queue def set_new_flag @__new_flag = true end def queue if defined? @__new_flag #queue remove_instance_variable(:@__new_flag) end # puts self.previous_changes end or inspect #previous_changes in after_commit . nil in id key should new_records. here's example output of previous_changes {"name"=>[nil, "newest"], "id"=>[nil, "cbdjzqgxir45xqj9uxgrsr"], "version_id"=>[nil, "cbdnaogxir45xqj9uxgrsr"]}

i have questions after reading article called layered application guidelines ( http://msdn.microsoft.com/en-us/library/ee658109.aspx ). for example, have asp.net mvc application. in application have entities (models), repositories, unitofwork , dbcontext. , views , controllers well. how split them layers according article above? as far understand, views , (maybe) controllers reside in presentation layer. entities (models) in business layer , repositories, unitofwork , dbcontext in data layer. am right or mistaken? i'm very-very unsure it. thanks in advance! views , controllers should reside in presentation layer. models should reside in presentation layer. models reflect view model used presentation only. entities should represent data , should not sent view. in presentation later, models should populated entities. correct in dbcontext , unitofwork should in data layer.

yeoman's deployment page, describes process of committing build folder (aka "dist") repo, pushing folder git subtree following command. git subtree push --prefix dist origin gh-pages i've got working fine, , able deploy build code dist folder build subtree branch (gh-pages in example above). can .gitignore dist folder master? if so, git subtree push --prefix dist origin gh-pages keep working? if not, how might avoid committing built source master branch, while keeping in git subtree deploying? (need keep in branch because use capistrano deployments, which, sort of, relies on deploying entire branch server.) .gitignore files not remove existing files repository, , not prevent committing files ignored. if ignore files after committed, stay in repository untouched, though changes them ignored. if want commit changes ignored file (or file committed , ignored), can use git add -f forcibly add ignored changes. to answer question more directly,
