i hoping optimizing query rails site: vacation has_many :departures has_many :photos departure belongs_to :vacation photo belongs_to :vacation i need find list of vacations ordered , displayed departure. if vacation has 2 departures, should show in list twice (once each departure). @dates = departure.find(:all, :order => "start_at", :include => [{:vacation => :photos}], :conditions => ["vacations.duration > 1 , start_at > ?", time.now]) the issue need collect future departures each vacation, results in new query each departure listed. any ideas on how better accomplish this? you don't have limit on query, wouldn't have need pulled memory? have array every future departure each vacation want display. so use array have. vacation_id = 3 # or whatever - in loop. @dates_for_vacation = @dates.select{|d| d.vacation_id == vacation_id}

context i'm learning c, , i'm trying reverse string in place using pointers. (i know can use array; more learning pointers.) problem i keep getting segmentation faults when trying run code below. gcc seems not *end = *begin; line. why that? especially since code identical the non-evil c function discussed in question #include <stdio.h> #include <string.h> void my_strrev(char* begin){ char temp; char* end; end = begin + strlen(begin) - 1; while(end>begin){ temp = *end; *end = *begin; *begin = temp; end--; begin++; } } main(){ char *string = "foobar"; my_strrev(string); printf("%s", string); } one problem lies parameter pass function: char *string = "foobar"; this static string allocated in read-only portion. when try overwrite *end = *begin; you'll segfault. try with char string[] = "foobar"; and should notic...

we have several tomcat servers serving content single domain (via apache httpd front end.) balance memory usage on 1 of our servlets. is, each server provides same web application, different data set. we'd implement single sign-on on our website. in other words, have httpd configured visitor http://example.com/reports/a/ goes reports.war on tomcat server a, while http://example.com/reports/b/ goes reports.war on tomcat server b. each url separate report, , can't fit both reports in ram on single server. as understand it, can't use tomcat clustering because that's designed server replication, i.e. identical servers identical data. i've looked session sharing via tomcat's persistentmanager , jdbc store, appears designed caching sessions, rather sharing them. am missing something, or going require fair amount of custom coding? (i'm willing try open source servlet container, such jboss or glassfish, if have built in.) as on same domain...

i've created markdown extension file (called mdx_xxx.py) django project i'm working on can't decide put it. the documentation says file should reside on pythonpath , i've seen several blog posts inviting put file in root directory of project. however, seems odd place me rather see in related application directory it's not on pythonpath anymore. could experienced django programmer shed light on issue? thanks requiring extension files live directly on python path, , not inside package, (imo) unfortunate limitation of python markdown implementation. if extension specific project, think putting in project root best option available. on other hand, if extension reusable in other cases, package simple setup.py , install virtualenv using pip, other dependencies.

i'd optimize following snippet using sse instructions if possible: /* * data structure */ typedef struct v3d v3d; struct v3d { double x; double y; double z; } tmp = { 1.0, 2.0, 3.0 }; /* * part should "optimized" */ tmp.x /= 4.0; tmp.y /= 4.0; tmp.z /= 4.0; is possible @ all? i've used simd extension under windows, have not yet under linux. being said should able take advantage of divps sse operation divide 4 float vector 4 float vector. using doubles, you'll want sse2 version divpd . forgot, make sure build -msse2 switch. i found page details sse gcc builtins. looks kind of old, should start. http://ds9a.nl/gcc-simd/

wix has ability replace stock images custom ones http://wix.sourceforge.net/manual-wix2/wixui_dialog_library.htm is there freely available sets of images installers use if wix stock ones don't suit our style. as being programmer should play strengths , not try graphic designer when i'm not. i'm not aware of any. rolled own using paint.net iswix provide images clients ( or management ) , let them fancy. it's branding after not mine.

are there general reasons not deal document's , element's prototype? i create own little framework, because current project doesn't need mass of features of existing frameworks. i don't need support browsers don't support element/document-constructor , not execute scripts not under control. so recommend extend prototype or should go usual way , create own objects element/document? do plan extend default dom elements? if so, please don't. juriy zaytsev (aka kangax) describes why not in what’s wrong extending dom .

i'm trying write unit tests controllers in spring mvc web app. have got comprehensive set of unit tests domain model, completeness want test controllers too. the issue i'm facing trying test them without loading spring context. thought around mocking, method in controller has @transactional annotation attempts open transaction (and fails nullpointerexception because no spring context loaded). code example: public class userscontroller { @autowired private usermanager usermanager; @transactional @requestmapping(method = requestmethod.post) public modelandview create(user user) { usermanager.save(user); modalandview mav = new modelandview(); mav.addobject("user", user); mav.setviewname("users/view"); return mav; } } so want test behaviour without loading context , persisting user. does have ideas on how can achieve this? cheers, caps i'd mocking way go here. @transactional annotation have n...

the method below exists in redcloth gem. my question is: construction "to(redcloth::formatters::html)" mean? "to" isn't method in class, nor in superclass (wich string class). cheers. christian. def to_html( *rules ) apply_rules(rules) to(redcloth::formatters::html) end when search entire redcloth source def to , besides finding couple of methods start to , you'll find exact method to in ext/redcloth_scan/redcloth_scan.rb.rl . there's 2 things happen here. first, file preprocessed ragel . question, may safely ignore fact , read past weird syntax in file. focus on ruby bits. second, class redcloth::textiledoc reopend here. means class in file , in lib/redcloth/textile_doc.rb same. to instance method available piece of code quoted.
