i knew of performance reasons in sql 7 days, same issues still exist in sql server 2005? if have resultset in stored procedure want act upon individually, cursors still bad choice? if so, why? because cursors take memory , create locks. what doing attempting force set-based technology non-set based functionality. and, in fairness, should point out cursors do have use, frowned upon because many folks not used using set-based solutions use cursors instead of figuring out set-based solution. but, when open cursor, loading rows memory , locking them, creating potential blocks. then, cycle through cursor, making changes other tables , still keeping of memory , locks of cursor open. all of has potential cause performance issues other users. so, general rule, cursors frowned upon. if that's first solution arrived @ in solving problem.

when paging through data comes db, need know how many pages there render page jump controls. currently running query twice, once wrapped in count() determine total results, , second time limit applied results need current page. this seems inefficient. there better way determine how many results have been returned before limit applied? i using php , postgres. pure sql things have changed since 2008. can use window function full count , limited result in 1 query. (introduced postgresql 8.4 in 2009 ). select foo ,count(*) over() full_count bar <some condition> order <some col> limit <pagesize> offset <offset> note can considerably more expensive without total count. rows have counted, , shortcut taking top rows matching index not possible. doesn't matter small tables, matters big tables. consider sequence of events : where clause (and join conditions, not here) filter qualifying rows base table(s). ( group by , ...

i have problem can perhaps solved in more efficient or clean way, current solution. over past days have gotten understanding of how xml serialization can controlled via attributes, 1 part of xml structure obscure, have not been able find smart solution. i have been handed xml schema, cannot altered, , must create c# class. the code bugs me following: <xs:complextype name="datareftype"> <xs:sequence> <xs:element name="data" type="datatype"/> <xs:sequence minoccurs="0" maxoccurs="unbounded"> <xs:element name="separator" type="xs:string"/> <xs:element name="data" type="datatype"/> </xs:sequence> </xs:sequence> </xs:complextype> <xs:complextype name="datatype"> <xs:choice> <xs:sequence> <xs:element name="dataowner" ty...

short version: if running program vs2008 in release mode, want use patha\externaldll.dll . if running program vs2008 in debug mode, want use pathb\externaldll.dll long version: have programm linked against external dll-files (vtk). have built external application myself in both debug , release mode. external dll-files located this: <some path>\debug\externaldll.dll <some path>\release\externaldll.dll (so called same, have different folders). i want step external code debug builds, want release builds use release dlls testing execution time (i process big datasets). linking according dlls easy, have project settings that. when executing, visual studio takes first dll finds within path environment variable. cumbersome solution idea: having path variable like: path=;%currentdllpath%; , setting currentdllpath in post-build-step. there no solution built-in vs2008? actually there built-in , easy way: the "environment"-variable within ...

i have view including toolbar , webview uiview uitoolbar uiwebview now make screenshot webview with: uigraphicsbeginimagecontext(articlewebview.window.bounds.size); [articlewebview.window.layer renderincontext:uigraphicsgetcurrentcontext()]; uiimage *screenimage = uigraphicsgetimagefromcurrentimagecontext(); uigraphicsendimagecontext(); but imagecapture starts top of screen. includes toolbar (even 20 empty pixel @ top statusbar) how can capture image thats actual in uiwebview? thanks chris your uiwebview backed own layer, should able grab displayed contents it: uigraphicsbeginimagecontext(articlewebview.bounds.size); [articlewebview.layer renderincontext:uigraphicsgetcurrentcontext()]; uiimage *screenimage = uigraphicsgetimagefromcurrentimagecontext(); uigraphicsendimagecontext();

i understand both supposed small, key differences between two? exokernel operating system mit (and class of it's variants) handles relatively little hardware abstraction. in exokernel, low-level responsibilities of controlling hardware (particularly memory allocation ) left in hands of developer. many developers prefer have os take more responsibility of such low-level tasks, because developers writing applications. an exokernel allocates physical hardware resources programs . allows program use library operating systems, linked in provide of abstraction exokernel isn't providing. developer can choose between abstraction models, or roll own. given application, may have great performance benefits. if don't know you're doing, can write programs explode when crash. most kernels more abstract physical hardware resources kind of theoretical model . developer interfaces model, handles finer points of dealing hardware internally. the term nanokern...

is there way make running junit test stop after test fails? yes ... ability (or lack of it) built various testrunners (console, awt, swing, ant, maven or 1 built eclipse, etc). you'll have control in documentation specific platform you're using.

i have db column serialized hash : class foo < activerecord::base serialize :bar end when store hash inside of bar few levels deep, deeper levels not seem deserialize when need them. objects 1 level deep deserialzed fine. however, objects 2 or more levels deep remain yaml classes. i tried manually deserializing using yaml::load() got error saying argument wasn't instance of io. does know why complete ruby object doesn't deserialize? edit : after further investigation, problem seems stem fact i'm calling virtual attribute serialized yaml. class foo < activerecord::base serialize :bar end class bar < activerecord::base attr_accessor :enabled end @bars = @foo.bar[:bars] @bars.each |bar| puts bar.enabled end yields: nomethoderror: undefined method `enabled' #<yaml::object:0xb6f11844> (irb):12 (irb):11:in `each' (irb):11 :0 does mean deserialization isn't "real", ie, yaml object acts simila...

i want create method this: private static void addorappend<k>(this dictionary<k, multicastdelegate> firstlist, k key, multicastdelegate newfunc) { if (!firstlist.containskey(key)) { firstlist.add(key, newfunc); } else { firstlist[key] += newfunc; // line fails } } but fails because says can't add multicast delegates. there i'm missing? thought delegate keyword shorthand class inherits multicastdelegate. firstlist[key] = (multicastdelegate)delegate.combine(firstlist[key],newfunc); with test: var data = new dictionary<int, multicastdelegate>(); action action1 = () => console.writeline("abc"); action action2 = () => console.writeline("def"); data.addorappend(1, action1); data.addorappend(1, action2); data[1].dynamicinvoke(); (which works) but tbh, use delegate in place of multicastdelegate ; largely hangover never worked. o...

i writing output module visualize data on program. if inspect code, add point coordinates string , add string textnode element. problem number of points can more 500000 is there better way write lot of text xml or ok? xmlelement points = doc.createelement("vtk", "dataarray"); string str = ""; (int = 0; < sim.numberofparticles; i++) { str += sim.pposx[i].tostring() + " " + sim.pposy[i] + " " + sim.pposz[i] + "\n" } xmltext coordinates = doc.createtextnode(str); points.appendchild(coordinates); for amount of data, use xmlwriter instead of xmldocument . streams , resources no problem more.

i have simple task, cannot find solution. have 2 tables, 'articles' , 'categories' my article table this: id | cat_id | title | content 1 1 blah content 1 2 1 blah2 content 2 3 2 blah3 content 3 my categories table this: id | title 1 category 1 2 category 2 you see have 2 articles have same cat_id. not want duplicate cat_id field. cannot use distinct, because articles, because want fields out. so if use distinct this: select distinct a.id, a.cat_id, a.title, a.content articles a i out, want output this id | cat_id | title | content 2 1 blah2 content 2 3 2 blah3 content 3 can me please !!! this query select first article (lowest id) each category select a.* article left join article a2 on a.id<a2.id , a.cat_id=a2.cat_id a2.id null it outer join other articles. join clause joins articles same category , smaller id. when there no matches (a2.id null), have ...

for reasons won't discuss, have determined mamp pile of crap haunts system, , unless remove fully, live in shame. i've done obvious thing , removed mamp directory applications folder, however, don't wandering files, , have itching feeling mamp put .sock files somewhere, or otherwise made mess in file system. what files mamp add system when it's installed, , they? if have proof mamp doesn't put files anywhere (besides /mamp dir), that's answer any! from help page : to "uninstall" mamp, have delete mamp directory , returns original state (mamp not alter on "normal" os x).
