in project, work 2 databases, in parts when need use secondary database, use: $newdb = $this->load->database("otherdb", true); or $ci =& get_instance(); $newdb = $ci->load->database("otherdb",true); to de instance. but when this, ion_auth fails keep connection original database , throw 2 errors: call member function result() in get_users_groups function, and: trying property of non-object in link_menu_acl function. i tried forcing reload default databse, "fixed" first problem. my guess when load secondary database, ion_auth lose connection default database, don't know how keep or reconnect use both databases. ok, problem main , secondary databases, had set "true" in persistent connect configuration, seems ion_auth "found" secondary connection , tried query on and, possible because "unknown error" returned false instead object. changing secondary database "pconnect&

i saw class a, after class definition class constructor: (@x=0, @y=0) -> @a = what @a = here? it helps @ generated output. // generated coffeescript 1.9.3 (function() { var a; = (function() { function a(x, y) { this.x = x != null ? x : 0; this.y = y != null ? y : 0; } return a; })(); this.a = a; }).call(this); so @a translates this.a . when this used @ top level, refers window . @a = a exports class onto window object. this done export library. example, window.$ = jquery or window._ = lodash .

i cannot understand following output. expect numpy return -10 (or approximation). why complex number? print((-1000)**(1/3.)) numpy answer (5+8.660254037844384j) numpy official tutorial says answer nan . can find in middle of this tutorial . you exponentiating regular python scalar rather numpy array. try this: import numpy np print(np.array(-1000) ** (1. / 3)) # nan the difference numpy not automatically promote result complex type, whereas python 3 scalar gets promoted complex value (in python 2.7 valueerror ). as explained in link @jonrsharpe gave above, negative numbers have multiple cube roots. root looking for, this: x = -1000 print(np.copysign(np.abs(x) ** (1. / 3), x)) # -10.0 update 1 mark dickinson absolutely right underlying cause of problem - 1. / 3 not same third because of rounding error, x ** (1. / 3) not quite same thing cube root of x . a better solution use scipy.special.cbrt , computes 'exact' cube root rather x ** (1

i'm hoping can me once again! i figured out how extract value rest response in simple scenario , pass value along preceding test step, however, i'm stumped on how extract value array within rest response (shown below) use in preceding test step. more specifically, i'm attempting extract 1 of "id" values within answerchoices. response payload: (get) localhost/ws/portal/survey/question/${create ux survey question#responseasxml#//*:id} { "id": 589, "isenabled": true, "type": "radio", "wording": "soapui test ux survey question", "answerchoices": [ { "id": 1546, "order": 4, "text": "choice4" }, { "id": 1543, "order": 2, "text": "choice2" },

having 2 strings like: string = "attagacctgccggaa"; string b = "gccggaatac"; i delete part common in both strings , rest concatenate it. have tell need delete left matched part get input attagacctgccggaa gccggaatac output attagacctgccggaatac firstly thought use pattern , seacrh it, not possible not know pattern in advance (the length of matched chars variable) then thought on search whole string b in a if had no succes, delete char in string a (last 1 since want preserve left unmatched string) , loop until have no more chars in b like string = "attagacctgccggaa"; string b = "gccggaatac"; int times = b.length; string wantedstring = string.empty; string auxstring = b; while (times > 0) { if (!a.contains(auxstring)) { //save last char , delete auxstring wantedstring += auxstring[auxstring.length - 1]; auxstring = auxstring.trimend(auxstring[auxstring.length - 1]); } els

i have relatively-positioned div wrapper, , want vertically-align div inside of it. various other stack answers seem suggest right way this: .vcenter {position: relative; top: 50%; transform: translatey(-50%); } that works great, single child element. want have 2 overlapping child divs, picture , text, both vertically-centered within wrapper div: <div class="wrap"> <div class="foo vcenter"></div> <div class="bar vcenter"></div> </div> this doesn't work - transform applies both children, second child offset vertically height of first child. i made simple jsfiddle may make clearer. is there way both elements each center if child? (ps - don't tell me replace them single div containing text , image background, need move independent of each other) you should use position absolute instead of relative: .vcenter { position: absolute; top: 50%; left: 50%; transform:

i'm new working kango , have setup basic extension already. conversion existing extension , far. however, docs feel little light when comes doing ajax call cross-domain. this existing code worked 100% in other extension framework: $.ajax({ url:url, success:function(data){ alert("success!") } }); i'm seeing 200 ok response, response empty , never see alert. i'm guessing comes down need use kango api? i've tried of documentation samples , nothing seems working. above inside content script, if matters. i'm trying pull file , read contents, seems more difficult should be. if wan't perform cross domain request content script, should use kango.xhr.send : kango.xhr.send({url: 'http://example.com/'}, function(data) { if (data.status == 200 && data.response) { kango.console.log(data.response); } else { kango.console.log('something went wrong'); } })

when navigate aртем.example.com , web browser convert url xn--a-jtbvok.example.com . there way convert xn--a-jtbvok aртем using php? currently using $_server['http_host'] fetch requested url. live examples here: aртем.lekintepls.se , åäö.lekintepls.se . i have no idea phenomena called, i'm sorry if duplicate. this notation called punycode or idna (internationalizing domain names in applications). you can use idn_to_utf8 , idn_to_ascii convert between 2 notations.

i'm having trouble iterating through series of nested hashes, , think because inner hashes named strings. unfortunately, cannot change these names. here generic hash of kind working with: hash = "name" => { "stuff" => "value", "key" => "value", }, "name" => { "stuff" => "value", "key" => "value", }, i'm trying write program print fields labelled "name" values, within, when called names of keys. right now, stuck hash.each |key, value| puts key key.each |stuff, info| puts info if category == "stuff" end end but gives error each not recognized method key, is, think, because computer treating string due naming. have ideas how can proceed here (without changing names of keys)? as @meager says - sub-hash in value. try this hash.each |key, sub_hash| puts key sub_hash.each |category, info|
