greetings all, i've seen similar questions asked before no conclusive or tested answers. i'm designing news feed system using php/mysql similar facebooks. seeing table grow quite large -- inefficiency result in significant bottleneck. example notifications: (items in bold linked objects) user_a , user_b commented on user_c's new album . user_a added new vehicle [his/her] garage. initially, implemented using excessive columns obj1:type1 | obj2:type2 | etc.. it works fear it's not scalable enough, i'm looking object serialization. so, example new database set so: news_id | user_id | news_desc | timestamp 2643 904 {user904} , {user890} commented on sometimestamp {user222}'s new {album724}. anything inside {'s represents data serialized using json. is smart (efficient / scalable) way move forward? will difficult separate serialized data rest of str...

i'm trying figure out how filter out duplicates in string regular expression, string comma separated. i'd in javascript, i'm getting caught how use back-references. for example: 1,1,1,2,2,3,3,3,3,4,4,4,5 becomes: 1,2,3,4,5 or: a,b,b,said,said, t, u, ugly, ugly becomes a,b,said,t,u,ugly why use regex when can in javascript code? here sample code (messy though): var input = 'a,b,b,said,said, t, u, ugly, ugly'; var splitted = input.split(','); var collector = {}; (i = 0; < splitted.length; i++) { key = splitted[i].replace(/^\s*/, "").replace(/\s*$/, ""); collector[key] = true; } var out = []; (var key in collector) { out.push(key); } var output = out.join(','); // output 'a,b,said,t,u,ugly' p/s: 1 regex in for-loop trim tokens, not make them unique

i created action filter want apply of controllers (including new ones introduced later on). i figure useful unit test 1 cycles through each controller , verifies if criteria met, action filter impact result. is wise create unit test hits multiple controllers? can share code similar test has proven useful? edit: realized testing action filter might problematic. still, if have thoughts share on mass testing of controllers... it not recommended test more 1 thing @ time in tests. you should avoid logic in tests (switch, if, else, foreach, for, while) test less readable , possibly introduces hidden bugs. many simple, readable, , therefore maintainable tests testing 1 thing each far preferable 1 test lot of complexity. response edit testing filters can achieved separating filter attribute. here example: loadmembershiptypelistfilter class has 'seams' needed use test fakes. logic in filter is tested. public class loadmembershiptypelistfilter : iaction...

i have std::vector (let's call "data_vector") want synchronize parts of across processors. i.e., want send values arbitrary indexes in vector other processors. i can boost's send() functions if want send whole vector, need send small portion of it. right have separate vector (let's call "idx_vector") containing indexes of data_vector want send, can change format if necessary. what's best way this? don't want iterate through , sync each index separately. copy values 1 contiguous vector , sync that, rebuild it, wonder if boost has better way. boost.serialization idx_vector containing pointers data_vector locations work? how that? serialization should work, since under hood mpi implementation sending array of bytes. mpi method of doing define mpi datatype picks out indices want send, in case mpi_type_indexed right option.

i building image editor silverlight 4.0 , need insight or possibly snippet of code or library implement contrast/brightness management. i appreciate if share how can achieved. thanks! contrast how "wide" swath of pixel brightness values present, out of total range of values possible. brightness "offset" of swath minimum possible level. to increase contrast, subtract (smallest present value - smallest possible value) pixel values put swath @ 0. multiply values (max possible value / max value present ) scale "swath" range of possible values. to adjust brightness, add or subtract absolute value each pixel. you want luminance or value channel in hsl or hsv colorspace. i found code here. http://www.dfanning.com/ip_tips/contrast.html

i once found slick looking car make/model dropdown menu web service advertised form helpers ruby on rails, have subsequently been unable find again googling it.... know service talking about? edmunds provides data free through api. have sign-up api key. see documentation here: http://developer.edmunds.com/api-documentation/vehicle/ sign-up key here: http://developer.edmunds.com/index.html one example of making call (many more examples given on site): https://api.edmunds.com/api/vehicle/v2/makes?fmt=json&api_key={your api key} i looking kind of information motorcycles. can tell api not provide motorcycle data, seems have cars - make, model, year, trim, style, maintenance schedules. with json or xml data, have roll own drop down menus. edmunds provide premade widgets, pretty specific (e.g. return true market value), there chance won't have need. http://developer.edmunds.com/widgets_and_apps/index.html

actually i've (probably) "simple" problem. don't know how cast signed integer unsigned integer. my code : signed int entry = 0; printf("decimal number : "); scanf("%d", &entry); unsigned int uentry= (unsigned int) entry; printf("unsigned : %d\n", uentry); if send unsigned value console (see last code line), signed integer. can me? thanks lot! kind regards, pro printf("unsigned : %u\n", uentry); // ^^ you must use %u specifier tell printf runtime uentry unsigned int . if use %d printf function expect int , reinterpret input signed value.

i'm working on mobile web app , i've noticed on both test phones, blackberry 9700 bold (os 5.0) , blackberry tour 9630 (os 4.7) not render width properly. i have simple table i've declared width 100%, table doesn't expand , take 100% of screen. there gutter / white border of 10px or right of screen. if hard code width 480px, takes entire screen, don't want hard code width values since may different depending on blackberry user using. i'm using meta tag: <meta name="handheldfriendly" content="true" /> , experimented setting viewport meta tag little success. any ideas? realize set width dynamically using javascript, i'd rather not. also, if save rendered page html , upload html server, when browse page blackberry width 100%! weird considering it's same code. perhaps wrong when page dynamically created , width gets messed up. anyone else experience this? i solved project. added min-width:470px divs not f...

basically, looking library solution this: #include <boost/type_traits.hpp> template<bool> struct bool_to_bool_type; template<> struct bool_to_bool_type<false> { typedef boost::false_type type; }; template<> struct bool_to_bool_type<true> { typedef boost::true_type type; }; is there such metafunction? boost already provides boost::mpl::bool_<> : boost.typetraits uses integral_constant : boost_static_assert(( is_same< integral_constant<bool, false>, is_class<int>::type >::value ));

i created instance variable (@user) in model of mailer , want access in view? it's giving me an error (@user = nil). what's best way pass variable view (the email body)? thanks, chirag if want access instance variable in mailer template in mailer model add @body[:user] = user_object the above create instance variable @user can accessed in view. should able access user object in mailer view doing @user the docs here have examples of alternative ways if using multiple formats (text/html).
