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

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...

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.

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 developing ssis transform component need store contents of incoming data stream , output data @ later point in time. large number of records many fields (of data type). for example, type of storage needed if developing 'sort' component, cannot output single record until records have been input. my question - recommended practice storing temporary data? microsoft , codeplex examples i've seen trivial in use in-memory structures. avoid this, seem bad idea when working large data sets. is there mechanism in ssis library this? [okay, looks there not] i'm considering few options: store data on disk in stream, keeping record offsets stream in memory. during output phase, i'll use these offsets locate desired record. store data in ado or oledb data source of user's choosing. other suggestions? no - there no 3rd-party accessible "buffering" mechanism exposed in api. you're responsible yourself, including paging disk or w...

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...
