apologies in advance if nubs problem. one friend got beginning rails 3 , started playing ruby using (as .net developers!). have installed ubuntu 10.10 on vmware player - apparently had ruby 1.9.2. based on instructions in book (with quirks total linux nubs) managed install ruby 1.9.1 (ruby --version -> ruby 1.9.1p376 (2009-12-07 revision 26041) [i686-linux]). but rails (latest version - 3.0.2 think) insist ruby 1.9.2 better our health! so: how update ruby on ubuntu 10.10? want 1 ruby there. i recommend ruby version manager . install (yes, takes leap of faith): $ curl https://get.rvm.io | bash then $ rvm install 1.9.2 $ rvm use 1.9.2

does else think silverlight 4 security bit screwball? look @ following scenario: silverlight when set trusted app, , run out of browser mode allows browse file using file open dialog. you require name of path of file open com automation. example (excel/word) anything. it impossible full path of file dialog because of security restrictions you can using com filesystemobject - ever want users file system, including create folders, move , delete files. so in other words, why fuss security in silverlight, hinders real business use cases, when possible access file anyways using com? to way, if user runs malicious silverlight app, unlikely they'll - oh com @ fault. com afterall being called silverlight app. here mean.... user browses file - c:\myfile.xls silverlight prevents getting path (for security reasons) silverlight lets work documents using com can ever want file system in background anyways. including copying file documents, if knew name! besides can wipe

i having hard time solving following mvc view. my goal display data multiple tables in single mvc view. bulk of data comes table called retailers. have table called retailercategories stores retailerid retailers table , categoryid linking category table. note there multiple records each retailerid in retailercategories table. in view want show list of retailers , each retailer want show list of categories applicable them. what best way accomplish this? of things have tried covered in can mvc viewmodel issue? this not appear right approach. you need view model tailored needs of view. when defining view models shouldn't thinking in terms of tables. sql tables have absolutely no meaning in view. think in terms of information need show , define view models accordingly. use automapper convert between real models , view model have defined. so forget said tables , focus on following sentence: in view want show list of retailers , each retailer want show

we're in process of developing service , hr service purposes of user management, we're having trouble deciding best way structure projects. one dev believes project , hr project's should separated in subversion , should use svn externals each messages project? another dev thinks should put them in same subversion project partition services having all.sln, hr.sln, , it.sln splitting them folders. what best way partition these service boundaries? i'm not familiar subversion, typically have done have dependencies between services checked source control post build , branched respective service after. reason done allow each service independently decide when take newer version of shared dependency. using branch operation have full history of dependency , can roll @ time. gives ability ship service different versions of same dependency. in subsequent branches of service can have varying versions of dependency. in case check-in messages assemblies , bra

ok, maybe dumb question , i'm not seeing button...but how rerun checked tests in sl unit testing application ui? i launch unit test app, let run tests.....then can check or uncheck tests when completes....but how rerun checked tests without restarting whole darn thing? don't see button "run selected tests"..... honestly, hope i'm being stupid this. i posted same question on codeplex, got not answer. sent direct email creator of framework, got no answer. this tells me of couple of things: i'm dumb i've missed terribly obvious. no 1 uses silverlight production applications or @ least none require unit testing, no-one knows answer here. microsoft's commitment silverlight , support sub-standard, @ best. i've gotten unlucky in hopes support on matter. that said, found answer myself. in app.xaml.cs: private unittestpage _page; in application_startup: rootvisual = _page = (testpage) unittestsystem.createtestpage(); add

i'm working on android, , i'm new graphics. i have particles don't want affected lighting. right now, disabling lighting right before draw particles (gl.gldisable(gl10.gl_lighting)), , enabling them again once they're drawn, , continue drawing rest of scene. would more efficient leave lighting on, , set particles emissive? (by calling glmaterialfv( gl_front_and_back, gl_emission, white) right before drawing particles) there's no easy answer here, i'm afraid. anon commenter says, you're best off measuring yourself. bear in mind results hardware-dependent. disabling lighting less work hardware, state change may disrupt processing pipeline such saving negated.

i see great deal of writing silverlight 4's support drag , drop. however, files. want make normal user controls draggable. possible, or limited files? you can add drag-and-drop capabilities element of silverlight application - not limited files (this became easier in 4.0). using attached behaviors , drag-and-drop management code should able achieve interaction need. without knowing hope accomplish, best advice go check out projects like: http://silverlightdragdrop.codeplex.com/ and read discussion here: silverlight 4 drag , drop alternatives

i have been debugging in gdb (c code). issue if run application , if crashes, control comes main()(app restarts). hence have no idea crashed. spend lot of time stepping through each function. i know if there anyway log can enabled generate last line of execution before crash. assumption, if there other simpler way of doing please let me know, save great deal of time me! also if gdb generates log path be? thanks in advance. this question little unclear me, i'll take stab: if have gdb attached crashing process when crashes, crash should stop program , put @ (gdb) prompt. if type bt , should see stack. if not have gdb attached, this answer related question might help. (in short, maybe want system create core dump when program crashes. core dump file contains lot of information crashed process. can use gdb core dump see stack.) if don't know, post see on screen when happens, , we'll guess. in case, program should not start on @ main(). seems wort

when typing javascript object literals, such as: foo = { bar: baz }; vim thinks "bar:" c-style label , moves column 0. how stop this? try :set cinkeys-=: . label indentation cannot controlled cinoptions . quote :help indent vim puts line in column 1 if: it starts '#' (preprocessor directives), if 'cinkeys' contains '#'. it starts label (a keyword followed ':', other "case" , "default"). any combination of indentations causes line have less 0 indentation. (emphasis mine) however, cinkeys specifies keys trigger reindenting in insert mode. removing : cinkeys , vim no longer reindent on inserting : . but aware manual re-indenting via = will still break layout.

i'm programming noob , didn't quite understand concept behind callback methods. tried reading in wiki , went on head. can please explain in simple terms? the callback pass function, tells should call @ point in operation. code in function decides when call function (and arguments pass). typically, way pass the function itself 'callback', in languages functions objects. in other languages, might have pass kind of special thing called "function pointer" (or similar); or might have pass name of function (which gets looked @ runtime). a trivial example, in python: void call_something_three_times(what_to_call, what_to_pass_it): in xrange(3): what_to_call(what_to_pass_it) # write "hi mom" 3 times, using callback. call_something_three_times(sys.stdout.write, "hi mom\n") this example let separate task of repeating function call, task of calling function. that's not useful, demonstrates concept. in real world, callback

there many samples demonstrating in xaml, such following: <treeviewitem> <treeviewitem.header> <stackpanel orientation="horizontal"> <image source="..."/> <textblock>hello</textblock> </stackpanel> </treeviewitem.header> </treeviewitem> but need in runtime code - purpose of treeview show files , folders on computer. so i'm not sure how work header in code: each f in directory.getfiles() dim icon = system.drawing.icon.extractassociatedicon(f.fullname) dim name string = f.name dim item new treeviewitem item.header = ... next can demonstrate concept please? edit: think i'm getting it, should use horizontal stackpanel 2 separate controls - textblock , image. right approach? . here sample code how should start. understand first, , make appropriate change meet need. code written in c# , xaml. hope you'll understand c# , able convert bas

in java, i'm trying retrieve hashmap<string, object> has object is: hashmap<string, object> . i implemented recursive function returns either hashmap<string, object> found given key, or null if key wasn't found. here function: public static hashmap<string, object> gethashmap(hashmap<string, object> map, string key) { (map.entry<string, object> entry : map.entryset()) { if (entry.getvalue().getclass().getname() == "java.util.hashmap") { if (entry.getkey() == key) return (hashmap<string, object>) entry.getvalue(); return gethashmap((hashmap<string, object>) entry.getvalue(), key); } } return null; } it works first item. how traverse hashmap of hashmaps? better approach? instead of returning value here: return gethashmap((hashmap<string, object>) entry.getvalue(), key); you want first check if not n

i able bind combo box selected item of row selected in datagrid. want able through xaml only. what binding syntax required combobox bind selected item of data grid? thx this should work: <sdk:datagrid itemssource="{binding items}" x:name="mygrid" height="100" verticalalignment="top"/> <combobox x:name="results" margin="0,100" selecteditem="{binding selecteditem, elementname=mygrid, mode=twoway}" itemssource="{binding items}"> </combobox> you bind selected item of combo box selected item of data grid. done via elementname. hope helps. tj

is there significant difference if construct jquery object around element once or many times? instance: var jel = $(el); $.each(myarray, function() { jel.addclass(this); } versus: $.each(myarray, function() { $(el).addclass(this); } i know there other ways write might sidestep issue, question whether should work $(el) once, or if irrelevant. example contrived. bonus points explaining $(el) behind scenes. i know theoretically more work being done, don't know whether matters... if jquery caches or browsers @ second request or whatever, not worth it. fyi: relevant jquery api link here (which provide because $() isn't easiest thing google for): http://api.jquery.com/jquery/#using-dom-elements also worth including useful link: http://www.artzstudio.com/2009/04/jquery-performance-rules/ , several of points center around saving, chaining, , selecting well. yes, there performance impact. in first example, 1 instance created. in second, instan

we're using indexing service query language (a.k.a. dialect 2) , following query, @taxcategory "\areas\technology\" , @xmlconfigid = 14 it unexpectedly matches following 2 items instead of first: technology technology, media & entertainment we expected ending slash constrain search item; appears grab having given text @ beginning of string. how write queries target first , second items independently? update: content indexed indexing service this: <ekttaxcategory>#eksep# \areas\technology #eksep#</ekttaxcategory> and <ekttaxcategory>#eksep# \areas\technology, media & entertainment#eksep#</ekttaxcategory> respectively. because substring #eksep# appears @ end of we're seeking, seen example of indexed items in question, ended solving issue using query: @taxcategory "\areas\technology#eksep#" , @xmlconfigid = 14 we considered using unix style pattern matching in query , period . stri
