i have report consists of single column tablix single row grouped. inside row 3 sub reports. header of report supposed display 3 pieces of information unique data row grouped on header unique each. i attempted populate data in header having hidden controls in body referenced in expressions of controls in header. method didn't work. switched different possible solution found populate variables using vb , reference them in header using =code.variablename in expression. function populate variables called hidden control in body passes data parameters. this method worked. however, seems work on local machine , 1 of coworker's machines in bids preview. when report published report server, runs , seems fine, except header values don't populate. one of variables integer , other 2 strings. integer value initialized 0 , in report report server shows initialized value of 0, strings still blank. makes me think function isn't being called or there might scope issue? or di

some of python shell scripts newly throwing security errors under apple osx 10.11, el capitan. seems new app transport security doesn't how scripts calling http resources in plain text, rather using https. fetching http://blahblah.com python[5553:5648168] app transport security has blocked cleartext http (http://) resource load since insecure. temporary exceptions can configured via app's info.plist file. how might go fixing this? there no https resource can call, i'm stuck http. advice apple make exception in app's info.plist file, python script invoked shell script, there no info.plist file edited. ideas? root problem seems webkit2png, in python. non-https requests being blocked ats, , there no info.plist modify. i found solution here worked me: https://apple.stackexchange.com/questions/210588/how-does-one-configure-a-temporary-exception-to-ats-on-el-capitan-and-fix-webkit first make sure have version of webkit2png new enough have --ignore-

i need this, i'm having sorts of problems: class myclass { } class someclass { func callmethod(object) { let thetype = object.type // need same result myclass.self let newinstance = object() // need same result myclass() } } let someclass = someclass() let object = myclass someclass.callmethod(object) how this? i want able specify 1 type (e.g. myclass). can either type name or instance of , 2 values shown in code comments. it lot easier if passed in 2 separate variables, i'm sure can in one. you can use .dynamictype property of instance type. can call required init method on (or other class / static method). let thetype = object.dynamictype let newinstance = thetype.init() note : code compiles, depending on type of object . if type has required init() method, safe call on dynamictype . however, appears if type nsobject compiler let call init() on dynamictype though subclass may or may not have init() method given how swift ini

if understanding correct, there large range of uuids assigned in specification - there's this . since ibeacon's uuid can customised, wouldn't uuid conflict existing codes , create undesirable outcomes? if understanding correct, service uuids @ byte 30 , 31 of ble packet, overlapped ibeacon's uuids. service uuids 2 bytes can't hard collision occur. it important understand there 2 types of bluetooth advertisements: service advertisements manufacturer advertisements advertisements must 1 type or other, not both. only service advertisements use service uuids (either 16 bit or 128 bit). manufacturer advertisements not. manufacturer advertisements have 2 byte company code registered bluetooth sig. else in manufacturer advertisement arbitrary data. beacon types altbeacon , ibeacon manufacturer advertisements, not contain service uuids. there therefore no possible overlap between proximityuuid , service uuid, different things. other beaco

i'm working on website 500,000 users, issue im having when user goes create new account wait time extremely long because check if user exists using query. select count(username) usernametotal user_table username = 'hellokitty' i decide if can create account based on if usernametotal greater 0. i going index column think slow when try add user table, indexed column table need recreated every time user added. is there faster way , should column indexed? for query: select count(username) usernametotal user_table username = 'hellokitty' you want index on user_table(username) . however, not efficient approach. should keep same index , use exists : if (exists (select 1 user_table username = 'hellokitty')) begin . . . end; this should faster aggregation version, because can stop @ first matching row.

according java language specification, section 5.1.7 , java caches integer s -128 127 performance optimization. so when compare a == b , a & b integers in caching range, returns true though they're different objects. mechanically, performance benefits result caching? according this answer, "the purpose save memory, leads faster code due better cache efficiency." how lead faster code? how might use feature improve performance in real code write? does have following method found in integercache class? public static integer valueof(int i) { assert integercache.high >= 127; if (i >= integercache.low && <= integercache.high) return integercache.cache[i + (-integercache.low)]; return new integer(i); } the performance benefit nothing == . real reason cache allows valueof avoid creating lots of objects when same "small" integers boxed repeatedly. integer objects occupy space (at least 16 bytes). crea

i know how can change position of userannotationview? have tried: * change position of view, user location changes , annotationview go user location, stopped location updates location manager. * create copy of annotation view , added subview can see square in view hierarchy debugger, not display on mapview if know how can create view same animation of blue dot, fine or if have class imitating same behavior of view. if have idea, let me know... in advice why want change user annotation? annotation object represent user’s current location. if want change annotation, set map.showsuserlocation false , set custom annotation on location want to. but shouldn't change userlocation annotation , don´t think it´s possible.

i`m developing apps , hosting them on heroku there problem indexing website if publish top level domain there conflict between heroku sub domain , main one, search engines index both for example if domain something.com and heroku sub domain something.herokuapp.com what should delete heroku sub domain , make visible on main one? thank you it not possible right now. heroku proposes implement 301 redirect in such case. because don't have access configuration of web server or proxy on heroku side, option implement in application code. this information specified here : your app’s heroku domain remain active, if you’ve set custom domain. if want users use custom domain exclusively, app should send http status 301 moved permanently tell web browsers use custom domain. host http request header field show domain user trying access; send redirect if field example.herokuapp.com.

i have ordered stream of data a a b b c c c c ... (very long) and want transform stream of aggregates in form (item, count): (a, 3) (b, 2) (c, 4) what operators use in akka streams this? source.frompublisher(publisher) .aggregatesomehow() // ? .runwith(sink) i've looked .groupby requires know number of categories in advance don't. believe keep groups in memory i'd avoid. should able discard (a, 3) after has been processed , free resources consumes. edit : this question ask similar functionality using subflows. using subflows doesn't seem required because have solution using statefulmapconcat combinator. one option use statefulmapconcat combinator: source(list("a", "a", "b", "b", "b", "c", "c", "")) .statefulmapconcat({ () => var lastchar = "" var count = 0 char => if(lastchar == char) { count

"scripts": { "build": "webpack --config webpack.prod.js", "postinstall": "npm run build", "server": "h
