i understand why rails index method use plural form of resource - we're showing projects , example. and understand why show method use singular form - want see 1 project , particular id. but don't understand why new , create use plural. there way create more 1 project @ time? there other reasoning using plural here explain? new , create aren't plural, in way think rest. instead, think like: whatever.com base domain, , whatever.com/books means have collection of resources each named book. collection named books. so, when want create new book, asking collection information needed create new book. becomes /books/new when create book, posting information /books . http verb post, when post collection, execute create action. this looks good starting point on rest.

i in following situation. make real world case put things clear. suppose have model cube in 3d space, , cube has specific material: object of type cube contains set of information spatial position, , type of material, string. cube passed around many algorithms , classes, can perform tasks, such rendering cube. for happen, these algorithms , classes require additional info object, namely, material properties such reflectiveness. these info not specific object, can obtained means of current object data (namely, material cube made of). technically, have database of materials, can resolve string declaration of material specific cube detailed info specific material. renderer need these info, in following possible situations: i pass cube and database renderer, , let renderer query database, info material, , render cube i make database global object, can queried regardless of position in code, saving need pass database around, creating implicit dependency against database i data

-r filename --just-symbols=filename read symbol names , addresses filename , not relocate or include in output. allows output file refer symbolically absolute locations of memory defined in other programs. may use option more once. for example, on mac, ld -r libsomething.a or gcc -wl,-r,libsomething.a doesn't work. since you're talking "your mac", assume talking os x operating systems. on unix-based systems linker " ld " (with -r option) used of times (see also: elf ). in contrast os x systems use mach-o binary format , tool dyld linking. os x doesn't provide same features libraries unix does. try otool -l on binary see libraries expected. may want try setting dyld_library_path ( man dyld ) binaries keep in mind security risk (this used inject code ld_library_path on unix-systems).

i hava simple program video recording . use surfaceview show preview screen. , want put buttons on screen. i put component mentioned above xml file "ipcam.xml" i use mediarecorder , surfaceview , surfaceholder complete program because preview screen not orientate correctly when rotate phone. use "setrequestedorientation(activityinfo.screen_orientation_landscape);" , button in program in landscape direction . not auto change direction when rotate phone , preview ok!! so there anyway solve problem. thank in advance. you can see picture , put phone in vertical direction preview screen seems ok button in horizontal direction , don't want it. https://newslab.csie.ntu.edu.tw/~poc7667/123.png try this: <activity android:name=".myactivity" android:label="@string/app_title" android:screenorientation="landscape" android:configchanges="keyboardhidden|orientation"> </activity>

in order make visual c++ program more robust i'm tempted insert checks guid variables contain valid version 4 guids (and not left uninitialized): guid guid; uuidcreate( &guid ); // many lines of code later... // following assert should not fire valid version 4 guids int data3 = guid.data3; assert( ( data3 >> 12 ) == 4 ); i'm sure guids either come within uuidcreate() function or uninitialized variables (and latter i'd diagnose checks). concern microsoft change guid implementation in future versions of windows. what other factors should consider decide whether such checks won't hurt? how guid implementation changes on future versions of windows? my concern microsoft change guid implementation in future versions of windows. deal it, if happens. no, seriously, worry implementation of integer , microsoft decide switch .net datatypes , make integer system-wide 4-byte value. worry other things, if implementations changing, you'll h

(note - re-post first question got posted under wrong headline: here sorry!) i have standard wpf treeview , have bound items view model classes. i wish handle behaviour when items double-clicked (opening documents visual-studio-style). i can event-handler fire in control housing treeview (xaml shown), how bind specific behaviour on view model classes - e.g. projectviewmodel? preferable bound icommand-implementer, used elsewhere... <treeview itemssource="{binding projects}" mousedoubleclick="treeview_mousedoubleclick"> <treeview.itemcontainerstyle> <!-- style binds treeviewitem treeviewitemviewmodel. --> <style targettype="{x:type treeviewitem}"> <setter property="isexpanded" value="{binding isexpanded, mode=twoway}" /> <setter property="isselected" value="{binding isselected, mode=twoway}" /> <setter proper

i know if there faster algorithm o(n) detecting if line intersects convex polygon. know algorithm when check every edge of polygon if intersects line , if number of intersections odd or even, looking if there exists faster example in o (log n) complexity. thanks lhf's answer close correct. here version should fix problem his. let polygon have vertices v0, v1, ..., vn in counterclockwise order. let points x0 , x1 on line. note 2 things: first, finding intersection of 2 lines (and determining existence) can done in constant time. second, determining if point left or right of line can done in constant time. we follow same basic idea of lhf o(log n) algorithm. base cases when polygon has 2 or 3 vertices. these can both handled in constant time. determine if line (v0,v(n/2)) intersects line (x0,x1). case 1: not intersect. in case line interested in either left or right of line splitting polygon, , can recurse half of polygon. specifically, if x0 left of (v0,v(

is there way detect if user's browser internet explorer using jquery? i have issue png graphics using ie , want swap them gif's if user viewing site ie. you can using $.browser , yes, it's bad idea use browser detection: if($.browser.msie) { /* ie */ } a better option instance $.support feature detection, this: if(!$.support.opacity) { /* ie 6-8 */ } $.support.opacity false in browsers don't support opacity in styling (though ie 7-8 handle transparent pngs file, still isn't ideal, depending on you're after...personally think you'd giving ie 7/8 users sub-optimal experience). what should really target ie6 doesn't support transparent pngs (without alpha filter), this: <!--[if ie 6]> <link rel="stylesheet" type="text/css" href="ie6imagestyles.css"> <![endif]-->

i must doing wrong, can't find on issue google. i'm using boto access sdb on amazon web services. can create new table, add items, , iterate on items in table, can't figure out how query them. "select" method there, "query" isn't. according documentation here: http://boto.s3.amazonaws.com/ref/sdb.html#module-boto.sdb.domain . it's possible use pythonic method query sdb, method doesn't exist me! here small snippet of code might describe problem: >>>domain = conn.get_domain('testtable') >>> domain.select() <boto.sdb.queryresultset.selectresultset object @ 0xb71bb2ac> >>> domain.query() traceback (most recent call last): file "<stdin>", line 1, in <module> attributeerror: domain instance has no attribute 'query' has method been removed reason? i'm no expert in crafting queries, pointing me additional documentation regarding using select method great!

does knows function validate if url valid or not purely in gwt java without using jsni i using 1 (making use of regular expressions): private regexp urlvalidator; private regexp urlplustldvalidator; public boolean isvalidurl(string url, boolean topleveldomainrequired) { if (urlvalidator == null || urlplustldvalidator == null) { urlvalidator = regexp.compile("^((ftp|http|https)://[\\w@.\\-\\_]+(:\\d{1,5})?(/[\\w#!:.?+=&%@!\\_\\-/]+)*){1}$"); urlplustldvalidator = regexp.compile("^((ftp|http|https)://[\\w@.\\-\\_]+\\.[a-za-z]{2,}(:\\d{1,5})?(/[\\w#!:.?+=&%@!\\_\\-/]+)*){1}$"); } return (topleveldomainrequired ? urlplustldvalidator : urlvalidator).exec(url) != null; }

i'm trying draw animated growing line using quartz 2d, adding points existing line, gradually on time. started drawing new line, in drawrect method of uiview, obtaining cgcontextref, setting draw properties, , moving first point (0,0). cgcontextref context= uigraphicsgetcurrentcontext(); cgcontextsetstrokecolorwithcolor(context,[uicolor bluecolor].cgcolor); cgcontextsetlinewidth(context, 2); cgcontextmovetopoint(context,0,0); later, in next drawrect call, tried extending line, again, obtaining cgcontextref, , adding new point it. gcontextref context= uigraphicsgetcurrentcontext(); cgcontextaddlinetopoint(context,x,y); but seems current cgcontextref doesn't have record of previous cgcontextmovetopoint command last drawrect call, therefore doesn't have reference started drawing line. am doing wrong here? there way refering drawn line? you need treat each call drawrect if starting scratch. if asked update subrect of view, should assume state associated

i use vim, debuggers used in modern ides such netbeans, visual c++, , eclipse , wondering if there debuggers except in standalone program? tried using gdb, seems debugging take lot longer using command line. tried ddd, little frustrating use since not display complex structures arrays. how debuggers in modern ides allow me click on down arrow view in arrays not know how in gdb or ddd. you have at: http://code.google.com/p/jswat/ it's standalone java debugger. i'm afraid doesn't support c++ debugging.

i have created server product connecting social network servers , sending data status update etc. server authenticated necessary social networks servers users using solution. actually, have no problem @ time, think will. my server open thousands of concurrent request neccessary servers via http c# httpwebrequest instance. know it's possible change concurrent request limits below propery. servicepointmanager.defaultconnectionlimit afaik, limit max 100 evet set more 100. so, faced bottleneck problem httpwebrequest change defaultconnectionlimit property of servicepointmanager. i know guys thinking this. have suggestions ? ignoring whether or not idea, have tried using unique connectiongroupname each request, e.g. guid.newguid().tostring()? connection limit per connection group may unless there global limit. should disable keepalive unless reusing group names subsequent requests. see answer httpwebrequest how handle (premature) closure of underlying tc
