i have following variable definition: @monday = (time.now).at_beginning_of_week i use in different models, controllers, , views. where can define (and how should define -- @@? ) can define once , use throughout rails application? should in environment.rb? should @@? i add application controller: before_filter :load_date def load_date @monday = (time.now).at_beginning_of_week end so accessible in of yours controllers , views. if want use in models, need param, on example scopes. controller place should pass variable model: @models = mymodel.before_date(@monday) i don't think need have 1 instance of variable whole application. initializing quite simple. not when initialize , don't use it. me hard imagine need in of controllers , actions. the other way can define class: class mydate def self.get_monday time.now.at_beginning_of_week end end and put in config/initializers (probably there better place put it). can access anywhere in a...

given array int [] myarray = {5,-11,2,3,14,5,-14,2}; i must able return 3 because longest down sequence 14,5,-14. what's fastest way this? ps: down sequence series of non-increasing numbers. just make 1 pass through list of numbers. pseudocode: bestindex = 0 bestlength = 0 curindex = 0 curlength = 1 index = 1..length-1 if a[index] less or equal a[index-1] curlength++ else //restart @ index since it's new possible starting point curlength = 1 curindex = index if curlength better bestlength bestindex = curindex bestlength = curlength next note: can ditch line containing bestindex or curindex if don't care knowing subsequence occurs, seen in gary's implementation.

i'm still wrapping head around of nuances of memory management in objective-c, , came following case i'm unsure about: + (nsdecimalnumber*)factorial: (nsdecimalnumber *)l { nsdecimalnumber *index = l; nsdecimalnumber *running = [nsdecimalnumber one]; (; [index intvalue] > 1; index = [index decimalnumberbysubtracting:[nsdecimalnumber one]]) { running = [running decimalnumberbymultiplyingby: index]; } return running; } here decimalnumberbymultiplyingby , decimalnumberbysubtracting creating lot of nsdecimalnumbers, autoreleased understand it, worry until time containing program hanging unto awful lot of memory. should introducing autorelease pool somewhere? (if where?) going have noticeable effect on performance (when compared side effect of memory in use)? is autoreleasing right mechanism use here? should @ breaking loop apart , manually releasing memory i'm done it? it's n00b question, i'm trying flavour best practice...

i'm using will_paginate (3.0.pre2) rails 3.0.0.rc. first page pulls fine when go page 2, returns nothing because query page 2 not being set correctly will_paginate. controller: page = params['page'].blank? ? 1 : params['page'] @posts = post.paginate_by_sql (['select * foo_table ids = ?', params[:ids]], :page=>page, :per_page=>50) @pag_params = {:ids=>params[:ids]} view: <%= will_paginate @posts, :params=>@pag_params %> link page 2 is: http://localhost:3000/posts/search?page=2&ids=1 logs show clause show incorrect (ids = 'search') when should (ids = '1') select * `foo_table` (ids = 'search') what missing query page 2 can corrected? talked developer of of will_paginate , found out best way attack using scoped_by_column_name(...column_value...).paginate(...conditions...) hope helps someone. :)

i trying translate existing c++ code c#. have code calls crypthashdata 3 times on same hcrypthash . documentation says "this function , crypthashsessionkey can called multiple times compute hash of long or discontinuous data streams." which want achieve in c#. unfortunately, md5.computehash() doesn't appear have way build on existing hash. am missing something, there c# api achieve this? instantiate instance of hash class , use transformblock , transformfinalblock : byte[] part1 = //... byte[] part2 = //... byte[] part3 = //... var hash = new md5cryptoserviceprovider(); hash.transformblock(part1, 0, part1.length, null, 0); hash.transformblock(part2, 0, part2.length, null, 0); hash.transformfinalblock(part3, 0, part3.length); byte[] res = hash.hash;

i have 15 integer column 5,000,000 rows in table. given input record containing 15 integers need compare input record 5,000,000 record table , obtain matching rows. note1: integers within row unique note2: order of columns matching , input record not important. example: 1, 10, 15, 23, 9, 22, 99, 11, 19, 32, 45, 21, 76, 12, 33 , 33, 10, 15, 99, 11, 19, 32, 45, 21, 23, 9, 22, 76, 12, 1 should yield match result is possible implement hashing function / bitwise operation generate unique index each row. function can return same index 2 rows if values in records same this isn't much, should started. you want hash function generates few collisions possible; has commutative (ie: order in add numbers hash irrelevant). can accomplish using combination of xor's , bit shifts (see page ). you might want store hash in column. can hash input looking , lookup hash on database. note hashes allow false positives, you'd still need check if candidate rows want (ie: sor...

size of array n.all elements in array distinct in range of [0 , n-1] except 2 elements.find out repeated element without using temporary array constant time complexity. i tried o(n) this. a[]={1,0,0,2,3}; b[]={-1,-1,-1,-1,-1}; i=0; int required; while(i<n) { b[a[i]]++; if(b[a[i]==1) required=a[i]; } print required; if there no constraint on range of numbers i.e allowing out of range also.is possible o(n) solution without temporary array. look first , last number calculate sum(1) of array elements without duplicate (like know sum of 1...5 = 1+2+3+4+5 = 15. call sum(1)). aaronmcsmooth pointed out, formula sum(1, n) = (n+1)n/2 . calculate sum(2) of elements in array given you. subtract sum(2) - sum(1). whoa! result duplicate number (like if given array 1, 2, 3, 4, 5, 3, sum(2) 18. 18 - 15 = 3. 3 duplicate). good luck coding!

i realize different beast used solve different problems, ask enumerated list of advantages of erlang on node.js (and vice-versa). when use 1 on other? erlang language , runtime. i'm assuming wish comparison of erlang runtime node.js first i'll list similarities: both lend event driven programming. both focus on highly asynchronous programming. and then advantages erlang has: erlangs message passing abstracts differences between local , distributed processes making distributed programming easier. erlangs hot code loading allows in place releases on running services without disrupting current activity. erlang has superior tools packaging , deployment. erlangs supervisor , gen_server behviors provide superior framework building extremely robust , fault tolerant systems.

is possible swap 2 variables without using ref/out keyword in c#(i.e. using unsafe)? for ex, swap(ref x,ref y);//it possbile passing reference but, there other way of doing same thing. in swap function can use temp variable. but, how swap variables without using ref/out keywords in c#? a (very!) contrived example using delegates: class program { static void funkyswap<t>(t a, t b, action<t> seta, action<t> setb) { t tempa = a; seta(b); setb(tempa); } static void main(string[] args) { string s1 = "big"; string s2 = "apples"; console.writeline("before, s1: {0}, s2: {1}", s1, s2); funkyswap(s1, s2, => s1 = a, b => s2 = b); console.writeline("after, s1: {0}, s2: {1}", s1, s2); } } while above pretty silly, using delegate setter method can useful in other situations; i've used technique implementing undo/re...

also, illadvised use rexcel corporate work? also, advantages / disadvantages of using it? how small files need rexcel? i have used in past, not using it. here's personal list of pros/cons: pro: easy access r functions excel allows slipping r logic existing excel spreadsheet fairly easy use syntax con: in instances can slow. if have 5000 calls r in spreadsheet can eat lunch while refreshes to share spreadsheet rexcel embedded, other users must have rexcel installed sometimes connection r drops , have reconnect it in opinion rexcel can useful hack, not make critical path along workflow. if need 1 or 2 functions r rexcel can lifesaver. i used rexcel speed slow excel spreadsheet replacing slow vba function fast 1 r. bought me time migrate whole process r made easier maintain , track. i'm not sure you're asking when asked "how small files need rexcel?" rexcel excel add-on, if data fits in excel can operate on it. if huge excel file...

does title attribute in link job of real text in link seo? i.e <a href="..." title="web design">web design</a> is same as: <a href="..." title="web design">click here</a> when trying page rank keywords "web design"? alt attribute in image tag? or useless in seo? is same as: <a href="..." alt="web design">click here</a> what's difference between above? thank in advance! alt not valid attribute <a> elements. use alt describe images use title describe link going. the textvalue (click here) important part title attribute gets more , more ignored. google looks far more on link text title attribute. google title tag meta tag not important compared content. image alt tags still important (especially image search) the main feature of tags provide usability users, not feed informatino search engines.

just starting getting entity framework , linq ef. i'm not sure of 2 query methods should concentrate on, method-based or query-based? is there obvious choice 1 easier use, both simple , more complex queries, hence should 1 concentrate on? assuming i'm using vs2010 method based have advantage in terms of having more design time checks/prompts ide make easier things right prior running application? thanks the method syntax more complete; there things can't query syntax without plugging in method here or there inline. also, queries, method syntax can seem more concise, imo. on other hand, query syntax can appear describe query more naturally familiar sql. i figured use method syntax exclusively when started learning linq in general. find myself pounding out query syntax queries sort of automatically @ times, too. perhaps concentrate on method syntax due completeness , familiarity factor (if @ valuable you), , maybe you'll find query syntax sort of ...
