i building website using django, , website uses blocks enabled page. right use textfield containing paths block enabled. when page requested, django retrieves blocks database , re.search on textfield. however, wondering if not better idea use separate db table block/paths, each row contains single path , reference block, in terms of overhead. i not familiar django, if understanding situation correctly, should use table. in fact kind of use db software designed , optimized for. no worries. faster. by doing search yourself, trying implement part of db logic on own. fun, certainly, not fast. :) here nice links on designing database: http://dev.mysql.com/tech-resources/articles/intro-to-normalization.html http://en.wikipedia.org/wiki/third_normal_form hope helps. luck. :-)

i trying write cucumber step definition when user visit sign page through credit referral.the url of sign page contains ref_id user id of referrer. how write step definition - when /^i visit sign page ref_id: "([^"]*)"$/ |arg1| ....????? end i figured out myself. here's web_step : when /^i visit sign page ref_id "([^"]*)"$/ |id| visit("/users/sign_up?ref_id=#{id}") end

i having boilerplate text should printed on bottom of last page of report. report builder wouldn't let me have "print object on" property "last" due reason suggested here: http://oracle.ittoolbox.com/groups/technical-functional/oracle-apps-l/error-while-setting-one-frame-property-to-last-page-914513 solution/workaround seems there in link in page isn't displayed site seems. if has workaround please me out here. edit: boiler plate text should outside margin per requirement along page number. thanks. i don't know "workaround" way i'd put object in normal print area, set print object on last page , , change margin printed @ correct location. page number still in margin, can offset page area sit on same line boilerplate text if wish. +------------------------------------------------+ | | | margin | | +-----------------------------------...

i'm on fence on how implement models. right i'm using polymorphic relationships, feels wrong, though convenient. feel should making use of database level integrity enforcement added layer of security. am grandpa questioning application layer? please discuss. i did find post, not rails specific possible mysql foreign key 1 of 2 possible tables? it depends. if application 1 access database (e.g. there no other tools writing it), can verify data integrity in application code. there things, however, still best done in database. validates_uniqueness_of example here. 2 app instances may report given value unique, there may race condition. having unique index in database here practice. i handle integrity checking in app code, using indices uniqueness constraints. don't bother foreign_key relations, let activerecord handle that.

possible duplicate: what's “@override” there in java? i've never put "@override" before method until now. see code examples it, don't understand utility. i'd love explanation. many thanks, jdelage first, can't annotate class @override . annotation indicates method declaration intended override method declaration in superclass. you don't have annotate overriding methods but if use annotation , annotated method does not override superclass method, compiler generate error message.

there multiple related questions, i'm looking solution specific case. there array of (usually) 14 integers. how can tell if each int appears twice (i.e. there 7 pairs)? value range 1 35. main aspect here performance. for reference, current solution. written resemble spec closely possible , without performance in mind, i'm can improved vastly: var pairs = array .groupby (x => x) .where (x => x.count () == 2) .select (x => x.tolist ()) .tolist (); issevenpairs = pairs.count == 7; using linq optional. don't care how, long it's fast :) edit: there special case int appears 2n times n > 1. in case check should fail , i.e. there should 7 distinct pairs. edit: result tested ani's , jon's solutions tiny modifications , found during multiple benchmark runs in target app ani's has twice jon's throughput on machine (some core 2 duo on win7-64). generating array of ints takes long respective checks, i'm happy result. th...

i'm working on personal project: creating library realtime audio synthesis in flash. in short: tools connect wavegenarators, filters, mixers, etc eachother , supply soundcard raw (realtime) data. max/msp or reaktor. i have working stuff, i'm wondering if basic setup wrote right. don't want run problems later on force me change core of app (although can happen). basically, start @ end of chain, @ place (raw) sounddata goes 'out' (to soundcard). that, need write chunks of bytes (bytearrays) object, , chunk ask whatever module connected 'sound out' module give me chunk. module same request module that's connected input, , keeps happening until start of chain reached. is right approach? can imagine running problems if there's feedbackloop, or if there's module no output: if connect spectrumanalyzer somewhere, dead end in chain (a module no outputs, input). in current setup, such module wouldnt work because start calculating sound-output mod...

i want declare string hold 4 chars char st[4]; memcpy(st,"test",4); but when print st ... have "test" , other symbols printed after - wrong in ? thanks lot c strings, "test" string literal, nul-terminated, meaning last character '\0': {'t', 'e', 's', 't', '\0'} you need use st[5] , , copy 5 characters, have room (and include) nul. is, you're not including in copy. aftewards, st looks like: {'t', 'e', 's', 't', x, x, x ... '\0'} when print, c keeps reading gibberish values coincidentally in memory (x'es above) until finds nul. the best solution eliminate memcpy , , let compiler figure out size initialization: char st[] = "test"; sizeof(st) 5.
