i'm creating ssis packages import large fixed width text documents , need transform various fields. 1 such field represents dates , 8 characters wide. format "yyyymmdd" , this: somedatefield 20130415 20110122 19891023 however, fields have blank spaces, , have zeroes 00000000. cannot converted date should return null value. i'm not allowed substitute date 1/1/1900. after futilely trying convert date field expressions, turned c# script transformation. my input column called ssolddate , readonly. i've configured output called solddate of dt-dbdate data type. the code came works is: datetime vardate; bool isparsed; isparsed = datetime.tryparseexact(row.ssolddate, "yyyymmdd", cultureinfo.invariantculture, datetimestyles.none, out vardate); if (isparsed) { row.solddate = vardate; } else { row.solddate_isnull = true; } i follow other date fields 1 in text

i not have need foreign language characters or collation since data received pure ascii. my concern performance in application code, , though have read many arguments varchar performs better nvarchar, did not discuss overhead converting , forth between windows unicode , sql server non-unicode varchar data? what bigger impact in general - performance within sql server dealing varchar vs. nvarchar, or performance in application, converting , forth between unicode on windows side , non-unicode on sql server side? understand there scenarios 1 perform better other, main scenario simple text search , retrieval through couple million records. using entity framework 6.1.3 dal. this concern , love feedback on having experimented or knowledgeable on topic. articles discussing varchar vs. nvarchar act sql database totally isolated in respect performance , external software not come play. there in fact unicode impedance mismatch between windows native use of unicode , ascii in database,

i trying design mlm application. operates person sponsors 3 persons , b, c, d , each of b, c, , d sponsors 3 more , on. to calculate payouts, client wants graph traversed based on last person of 3, d , total payout based on number of people under d multiplied specific amount. challenge me constraint whereby each level, need count n-1 persons n maxes out @ 3 mlm strategy. i using embedded neo4j project far know can traverse based on relationship , perhaps bread_first search , current depth how count number of persons minus 1 each level in traversal? seems, may have implement custom method need pointed in right direction. well, long know depth you're at, can use depth index collection (an array example). every time visit node @ given depth, increment value @ index in collection. once you're finished traversal, can apply ever rules , constraints array of data.

so in numpy arrays there built in function getting diagonal indices, can't seem figure out how diagonal starting top right rather top left. this normal code starting top left: >>> import numpy np >>> array = np.arange(25).reshape(5,5) >>> diagonal = np.diag_indices(5) >>> array array([[ 0, 1, 2, 3, 4], [ 5, 6, 7, 8, 9], [10, 11, 12, 13, 14], [15, 16, 17, 18, 19], [20, 21, 22, 23, 24]]) >>> array[diagonal] array([ 0, 6, 12, 18, 24]) so use if want return: array([ 4, 8, 12, 16, 20]) there in [47]: np.diag(np.fliplr(array)) out[47]: array([ 4, 8, 12, 16, 20]) or in [48]: np.diag(np.rot90(array)) out[48]: array([ 4, 8, 12, 16, 20]) of two, np.diag(np.fliplr(array)) faster: in [50]: %timeit np.diag(np.fliplr(array)) 100000 loops, best of 3: 4.29 per loop in [51]: %timeit np.diag(np.rot90(array)) 100000 loops, best of 3: 6.09 per loop

can please explain difference between these 2 functions? (function(engine, $, undefined) { //hidden scope //public function below engine.init = function() { console.log("im public"); } //anonymous functions below function login() { console.log("im private"); } })( window.engine = window.engine || {}, jquery ); specifically, i'd know why engine.init() available in console login isn't. init property of engine object refers function. can access other property. login local variable within anonymous, "immediately invoked function expression" (iife); other local variables, name visible within declaring function

i'm new in doctrine 2. have big problem on beginning, didn't find solution in google. want keep tree in db. found nestedset plugin ( https://github.com/blt04/doctrine2-nestedset ). downloaded it, , tried build tree. tried way (it's same in documentation): $config = new \doctrineextensions\nestedset\config($entitymanager, 'src\file'); $nsm = new \doctrineextensions\nestedset\manager($config); $mainfolder = new \src\file(); $mainfolder->setname('folder 1'); $nsm->createroot($mainfolder); but nothing. looked iside createroot() function, , figured out function flush() doesen't work: $this->getentitymanager()->flush() but don't know why. doesen't throw exception, , returns nothing. ideas? that extension found has 36 commits , updated year ago. might wanna check out extension https://github.com/l3pp4rd/doctrineextensions has 1312 commits , updated 2 days ago. can use build tree: https://github.

i'm trying learn unit testing, , have super simple class, unit test: public class homecontroller : controller { public actionresult index() { return view(new homeviewmodel { logourl = this.url.content("~/images/product.png") }); } } [testmethod] public void index() { assert.isnotnull(new homecontroller().index() viewresult); } i'm getting null reference exceptions. it's related using this.url() without httpcontext in unit test, believe. how can unit test pass while still using this.url() ? i'm fine using moq. :) the answer can found here example (gist): https://gist.github.com/johnnyreilly/4959924 here relating stack overflow question: asp.net mvc: unit testing controllers use urlhelper both should on right tracks. it comes down mocking httprequestbase , httpresponsebase can mock actual httpcontextbase , being used urlhelper class.

this project working on required me build moving animation uses nothing other css , styled divs. a perfect working example of identical can found here (note blue background white moving squares): http://www.braintreepayments.com however, unlike demo above, design consists of 10 times more div shapes in animation , when animation timing expires, container becomes blank, makes looks poorly designed. my question is, how animation in above example create 'continuous / infinite effect' on website, little styled divs? have been trying formulate replicate effect no success. note: open using jquery / javascript solution well. by using anitmation-iteration-count property , using infinite value - have hard time finding matching selector css minified, rule exists somewhere in stylesheet.

is possible use dayname output columname currently using this select *, left(thu,5) open1 ... ... but replace thu string dynamic current day(3 letters) , still use column name. the short answer no, can't done. column references (like identifiers) in sql statement static. identifiers can't replaced expressions determined @ runtime. the longer answer either need dynamically generate statement, or choose 1 of set of possible statements execute, based on whatever conditions. a third approach might want, referencing possible column names want select from, , making return column conditional based on day of week. something achieves same result: select left(case dayname(now()) when 'sunday' t.sun when 'monday' t.mon when 'tuesday' t.tue when 'wednesday' t.wed when 'thursday' t.thu when 'friday' t.fri when 'satur

with below code, when key pressed keycode pushed keymap array if it's not there , when key let keycode taken out of array. when testing out shoving keymap array console, found strange things. var keymap = []; $(window).keydown(function(e) { if($.inarray(e.keycode,keymap) == -1) {keymap.push(e.keycode);} }); $(window).keyup(function(e) { for(i = 0;i < keymap.length;i++) { if(keymap[i] = e.keycode) {keymap.splice(i,1);} } }); setinterval(function() {console.log(keymap);},100); if hold down , d @ same time keycodes present in keymap, if hold down w 3 of keycodes present. when let go of w it's removed array, d though i'm still holding down d. i found can hold down a, w, , d , they'll put keymap, not put w, a, , s in keymap when hold them down. combination of 2 of these put in, third not. can tell me what's going on? your comparison assignment actually. change if(keymap[i] = e.keycode) to if (keymap[i] == e.keycode) //

i have array contains integer values declared this: int data[] = new int[n]; each value needs processed , splitting work pieces can processed separate threads. array not modified during processing. can processing threads read separate parts of array concurrently? or have use lock? in other words: work order thread-safe? array created , filled threads created , started thread 0 reads data[0..3] thread 1 reads data[4..7] thread 2 reads data[8..n] reading contents of array (or other collection, fields of object, etc.) multiple threads thread-safe provided data not modified in meantime. if fill array data process , pass different threads reading, data read , no data race possible. note this work if create threads after have filled array . if pass array processing existing threads without synchronization, contents of array may not read correctly. in such case method in thread obtains reference array should synchronized, because synchronized block forces memory upd

can answer why core.preloadindex false default? there pitfalls? can't imagine performance penalty. why not default - well, introduced in 2008, , did improve performance on weak filesystems nfs, and... linus of opinion should made default - http://git.661346.n2.nabble.com/git-status-takes-30-seconds-on-windows-7-why-tp7580816p7580853.html i wonder if preloadindex shouldn't enabled default.. it's huge deal on nfs, , real downside expects threading work. potentially slows things down tiny bit single-cpu cases cached, isn't relevant case.

someone told service platform: http://particular.net/ implementing soa oriented applications. i find bit confusing @ first glance, ask questions it: services soap or rest? how data contracts , service contracts specified? are services externalizable outside consumers via wsdl metadata endpoints? a service not implemented in .net (java, ruby) can inserted in service bus? which protocol used messaging? what general thoughts service platform? for full disclosure, i'm founder of particular service platform, i'll try keep answers objective possible: services soap or rest? while platform allows use of wcf expose endpoints consumption 3rd parties, focus on queuing - msmq, rabbitmq, etc. how data contracts , service contracts specified? contracts message-oriented philosophical perspective, in practice they're regular poco classes , interfaces. are services externalizable outside consumers via wsdl metadata endpoints? see wcf comment
