i trying out hand in finding out records have been updated in oracle 11g db in last 24 hours or 7 days or 30 days. able desired functionality using "java.util.calendar" date today = new date(); calendar cal = new gregoriancalendar(); cal.settime(today); //for last 7 days cal.add(calendar.day_of_month, -7); however wondering if has done joda-time api? you need define exactly mean "last 24 hours" , "last 7 days". really mean last 24 hours, or "since same local time yesterday"? latter mean 23 hours or 25 hours, due daylight saving transitions. if really, want 24 hours , 7 * 24 hours, use instant : instant = new instant(); instant nowminus24hours = now.plus(durations.standardhours(-24)); instant nowminus7days = now.plus(durations.standarddays(-7)); note instant has no concept of time zone or calendar - it's just point on timeline; it's appropriate data type use timestamps , like.

i'm planning write algorithm use cgal delaunay triangulation data structure. need insert point triangulation, save reference cells, , make other insertion. i'm wondering how can store reference cells not invalidated after insertion of new points in triangulation? it's seems me cell_handle pointer internal structure, it's dangerous store due reallocation of internal container. in other hand can see no way in triangulation_3 interface store index cell_handle. typedef cgal::exact_predicates_inexact_constructions_kernel k; typedef cgal::triangulation_vertex_base_3<k> vb; typedef cgal::triangulation_hierarchy_vertex_base_3<vb> vbh; typedef cgal::triangulation_data_structure_3<vbh> tds; typedef cgal::delaunay_triangulation_3<k,tds> dt; typedef cgal::triangulation_hierarchy_3<dt> dh; typedef dh::vertex_iterator vertex_iterator; typedef dh::vertex_handle vertex_handle; typedef dh::point ...

i have 2 tables. need execute query gets name of product has letter m in , sort these products in descending order number of ingredients have. product table has name , product number in it, while table madefrom has ingredient number , product number in it. something this: select name, count(madefrom.id) product inner join madefrom on madefrom.productid = product.id name '%m%' group name order count(madefrom.id) desc

i have respond.php returns json data each http post different header data. efficient way generate roundly 30 requests @ once , handle responded data? needs efficient since hardware rather limited in performance. it not clear mean "generate roundly 30 requests @ once , handle responded data" . but efficient use of >>your<< time (and our time) implement in straight-forward fashion, , see if performance enough. pointless spend many hours coding ultra-efficient solution when simple solution going enough. the simple solution create 30 client threads , have each 1 send single post request using httpurlconnection. whether "efficient" depends on resources bottleneck. (and of course, same applies ideas on how make more "efficient".) saying hardware "rather limited in performance" doesn't give of clue ... once have simple solution, , you've identified actual bottleneck areas (client-side cpu? thread stacks? ...

this question has answer here: should 1 use dashes or underscores when naming gem more 1 word? 2 answers when create ruby gem , name it, paying attentions name '-' or '_' ? there differences use between '-' , '_'? $ gem list|egrep "\-|_" actionmailer-with-request (0.4.0, 0.3.0) activerecord-deprecated_finders (1.0.2, 0.0.3) activerecord-import (0.3.1) : : i feel there rules not sure @ moment. take learn rules or guidances if exist. , want take @ code of gems (near-)perfectly compliant roles if know gems named '-' or '_', please give answers well. there examples of gems don't follow convention. convention have come best using - denote namespace ( :: ) boundary , _ word separator within class name. examples: | main class | gem name | require | |-----------------...

kinda noob rails programmer, save me ton of headache. currently, i'm trying add validation devise sign on page, such allowing sign complete if email ends extension. know file location stands overlooks sign on page? i've looked on models , views can't seem find it. thank you! i think can use validates_format_of in user.rb model. can use rubular.com create regex. validates_format_of :email, :with => /myregexhere/

good evening, above exception when using hibernate jsf, saw many times in past , root cause <session-factory name="sessionfactory"> removed name , change generated code creating sessionfactory that: protected sessionfactory getsessionfactory() { try { return (sessionfactory) new initialcontext() .lookup("sessionfactory"); } catch (exception e) { log.error("could not locate sessionfactory in jndi", e); throw new illegalstateexception( "could not locate sessionfactory in jndi"); } } to that: protected sessionfactory getsessionfactory() { try { return new configuration().configure("hibernate.cfg.xml").buildsessionfactory(); } catch (exception e) { log.error("could not locate sessionfactory in jndi", e); throw new illegalstateexception( "could not locate sessionfactory in jndi"); } } ...

i'm working on go lang tutorial, ran problem 1 of exercises: https://tour.golang.org/methods/23 the exercise has me implement rot13 cipher. decided implement cipher using map byte rotated value i'm not sure of best way initialize map. don't want initialize map using literal, prefer programmatically looping through alphabet , setting (key, value) pairs within loop. map accessible rot13reader struct/object , have instances(?) share same map (rather 1 copy per rot13reader). here's current working go program: package main import ( "io" "os" "strings" ) type rot13reader struct { r io.reader } var rot13map = map[byte]byte{} func (rotr *rot13reader) read(p []byte) (int, error) { n, err := rotr.r.read(p) := 0; < n; i++ { if sub := rot13map[p[i]]; sub != byte(0) { p[i] = sub } } return n, err } func main() { func() { var uppers = []byte("abcdefghijklmnop...

assume class code: class foo { function method() { echo 'works'; } } is there way store reference method method of foo instance? i'm experimenting , fiddling around, goal checking whether php allows call $fooinstance->method() without writing $fooinstance-> every time. know write function wrapper this, i'm more interested in getting reference instance method. for example, pseudo-code theoretically store $foo->method in $method variable: $foo = new foo(); $method = $foo->method; //undefined property: foo::$method $method(); apparently, method method , i'm not calling () interpreter thinks i'm looking property doesn't work. i've read through returning references examples show how return references variables, not methods. therefore, i've adapted code store anonymous function in variable , return it: class foo { function &method() { $fn = function() { echo 'works...
