i need create dynamic redirection model rails app. sort of similar wordpress redirection plugin, if have used anytime. http://wordpress.org/plugins/redirection/ what model store redirect_this_path string, , final_path should redirected to. if user comes app requesting redirect_this_path , redirected final_path . if however, there no matching entry found in database, request should forwarded other routes defined in routes.rb file. so, redirection model filter requests , redirect requests has data , relay other requests routes defined in routes.rb file. is there way can achieved, suggestions? you should this: (for example in application controller) def path_check if request.path == path_that_needs_redirecting redirect_to final_path end end then use: (in application or every controller need in) before_filter :path_check hope helps edit if have many paths need redirecting do if paths_that_need_redirecting.include? request.path

i'm writing java code execute batch of insert statements oracle database. i've seen in of documentation ( http://docs.oracle.com/cd/b28359_01/java.111/b31224/oraperf.htm ) can use sendbatch() or executebatch() this. i'm little confused differences between 2 approaches are, or why choose on over other. maybe missed in readings. is there can explain differences are, , how can decide when should use 1 approach instead of other? sendbatch() oracle version of batching. oracle says using better fitting oracle , gives higher performance. oracle batching supports preparedstatement . executebatch() jdbc standard version. if program should jdbc compliant use method batching. might less performant (according oracle documentation), code compatible other jdbc drivers.

so whole point of meteor js allow user code whole stack @ once, if working on 1 of older frameworks django , borrow front end code meteor js ? example, front end syncing of database, templating, or how meteor handles events template, etc. is there way extract meteor js front end code used in framework? no, there's no such method. whole point of meteor (well, 1 of key points @ least) have 1 framework works both on front end , end. way don't have write 2 separate logic layers, nor additional layer communication between them. it's big advantage. that said, theoretically use meteor front end django end, provided talk server manually ajax , wrap data own reactivity. however, you'll end rewriting large part of meteor yourself. it'll easier either rewrite old django code in meteor, or use dedicated front-end framework backbone.

i have following datetime today = datetime.today; // or datetime.utcnow.date; now, can not in linq-ef because date can not translated sql: context.records.where(r => r.creationdate.date == today); so, this: datetime dayend = today.adddays(1).addmilliseconds(-1); context.records.where(r => r.creationdate >= today && r.creationdate <= dayend); now, there better way getting end of time datetime instead of adding 1 day taking 1 millisecond? the problem like datetime today = datetime.today ; context.records.where(r => entityfunctions.truncatetime(r.creationdate) == today) ; is underlying sql going this: select * some_table r convert(date,r.creationdate) == @today since column part of expression , sql engine unable make use of covering indices has available. unless you've got other criteria use indices, you're going table scan. , big tables, cause performance issue. and should avoid obvious datetime today = datetime.t...

i need simple javascript change value= attribute 2 when page loaded. <input type="number" step="1" min="1" name="quantity" value="1" title="qty" class="input-text qty text"> addeventlistener('load', function() { document.getelementsbyclassname('qty')[0].value = 2; }); you first add event listener load event, runs after page's loaded within event listener's callback function, select element. in script, select class qty , since class seemed specific of three. should add id attribute input accurately select though. you first result, @ index [0] , , set value 2.

i have tree of unknown structure. first, want find node containing string of text, "something". then, after identifying string's location in tree, want update different node relative string's location . data nested map several branches of lists. is possible zippers? i've studied approach editing trees: http://www.exampler.com/blog/2010/09/01/editing-trees-in-clojure-with-clojurezip/ . problem is, don't beforehand know location of string. yes! kind of task zippers designed for. repeatedly call zip/next until find node looking for. then call zip/path find out relative root. then call zip/up , zip/down , zip/left etc node modify. update node call zip/root new map containing these changes.

i trying make game pong ( math bad , working on it) , trying bouncing ball part. i trying calculate out going(reflecting) angel of ball after hitting walls or pedals (the walls horizontal , pedals vertical) here image demonstrate better : here tried far: var m = (y2-y)/(x2-x); var angle = (math.atan(-m)*57.2957795); how ever not seem work. since obstacles vertical or horizontal, not need angle calculations. if store ball's position (x, y) , it's velocity (v x , v y ) can @ each frame compute next position (x + v x , y + v y ) to bounce horizontal border, negate v y , bounce vertical borders negate v x .
