postgresql seems have environment file allows settings environment variables. on linux (kubuntu 11.10 in case), located @ e.g. /etc/postgresql/8.4/main/environment , empty default, apart few helpful comments. on mac osx lion, file not seem exist: expect @ e.g. /library/postgresql/9.0/data/ that's other configuration files are, not there - , if create it, not seem used. how can set environment variables postgresql server on mac osx ? there no standard way specify environment variables postgresql, assume file kubuntu specific. what did ease life copying approach used oracle: i have /etc/pgtab file on each server run postgresql databases; i specify each cluster run on single line in /etc/pgtab ; i've created script pgenv based on /etc/pgtab shows menu of clusters (in case there're more one) , initialize path s , variables. it works on macbookpro , on linux , hp-ux based servers.

i have website live , visible in google search want displayed in grid view shown in google search of key word example "twitter". can guide me how make happen? its called sitelinks . there's no explicit way can define sitelinks. it's google's algorithm decide links, if any, should appear on sitelinks. make sure site adheres google seo guidelines , if popular links enough traffic, may show sitelinks of search results.

i wondering, whether there way preprocess freemarker template rules - add syntactic sugar, not directive, nor method. fo instance have variables, print this: ${item.getlocale(currentlocale).name} ${item.getlocale(currentlocale).text} ${item.parent.getlocale(currentlocale).name} ${item.parent.getlocale(currentlocale).text} obviously, getlocale construct makes whole expression pretty ugly. achieve able write: ${item.l.name} ${item.l.text} ${item.parent.l.name} ${item.parent.l.text} so .l. during compilation rewritten .getlocale(currentlocale) . is there nice way that? thanks! this pretty why object wrapping exists in freemarker; can present data templates in custom way. suppose item belongs specific java class. extend defaultobjectwrapper or beanswrapper wrap items specially, , use configuration.setobjectwrapper(new yourobjectwrapper()) once initialize freemarker. (see source code of defaultobjectwrapper example of customization; extends beanswrapper wrap

i need forward set of sequences dml access. due bug in piece of code several values grabbed without sequence instead manually, sequence duplicating values. so, push sequence max value next time nextval called, gives value higher maximum. i've got 50 sequences each have go few thousand forward. is possible dml access? if so, how should go it? you can use dynamic sql this. example, bit of code select next 10,000 values each of list of sequences. declare l_num integer; begin seq in (select * all_sequences sequence_name in (<<list of 50 sequences>>) , sequence_owner = <<owner of sequences>>) loop in 1 .. 10000 loop execute immediate 'select ' || seq.sequence_owner || '.' || seq.sequence_name || '.nextval dual' l_num; end loop; end loop; end; if had ability issue ddl against sequence, use similar approach set increment 10,

i not sure if using right term curious if there more efficient way of doing things. have file loader deals numerous fragments (about 30 in total). class littered with: void fragment_03(char* location, int frag_num); void fragment_04(char* location, int frag_num); void fragment_05(char* location, int frag_num); void fragment_06(char* location, int frag_num); ...and forth. there way better way declare these functions in more generic way rather writing out 30 different function declarations? thanks! i'm not sure if want do, but: you have declare , define of functions separately, can store function pointers in array. typedef void (fragment_function) (char* location, int frag_num); frag_function fragment_0, fragment_1, fragment_2; //define functions in cpp file fragment_function *fragment [] = { fragment_0, fragment_1, fragment_2 }; then define them this: void fragment_0(char* location, int frag_num) { /**your definition here*/ } so can called

i'm working on embedded linux video recorder application writes mp4 format video file (on fat format sd card). some complicating factors video , audio data come hardware codecs have serviced low latency, , must write dma-capable buffers. at moment output file use open() , write(), find write() can take hundreds of milliseconds return when system under load, writes done in separate thread. as stands copy data (small, limited number) dma buffers multi-megabyte malloc'd circular buffer, write() in thread. means i'm doing @ least 2 copies, once app buffer, , once system buffer cache. i considering trying o_direct writes avoid copy, interested in comments. note robert love comments o_direct terrible not why. on flip side, interested if knows way write() not stall longish periods of time (aio?), use buffer cache linus intended. this question not unrelated my old question write stalls . if embedded product in control driver source, i'd looking mmap

i'm looking classy strategy retrieve current user information emberjs (and ember-data). currently, following : my api responds /users/me current user. in adapter, when retrieved object id isn't 1 i'm hoping for, add real_id id (the user's id in database) , replace real returned id i'm expecting. so when adapter has "me" user's id, server returns 1, following json : {"real_id": 1, "id": "me"} this works. i'm not big fan, , i'd avoid mush possible change default content of adapter. do use strategy ? recommend ? i use controller app.currentusercontroller this. app.currentusercontroller = ember.objectcontroller.extend({ content: null, retrievecurrentuser: function() { var controller = this; ember.$.getjson('/users/me', function(data) { app.store.load(app.user, data); var currentuser = app.store.find(data.id); controller.

as know, returning false dom event handler stop propagation of event. discovered behavior of different elements varies respect event. example, consider following: <div id="container"> <input type="checkbox" name="foo" value="1" /> check me! <br /> <select> <option>1</option> <option>2</option> <option>3</option> </select> <br /> <input type="text" size="30" /> </div> the surrounding container has click handler returns false: $('#container').click(function(e) { $('#clicks').append('<span>clicked</span>'); return false; });​ within div , can still click on text box , enter text, , can still click on dropdown change value. clicking on checkbox nothing (actually, that's not quite true - checks box, fires handler, unchecks it). jsfiddle here: http://jsfi

why code work (i see output 1 2 3): for in 1..3 thread.new{ puts } end however, following code not produce same output (i not see output 1 2 3)? for in 1..3 thread.new{ sleep(5) puts } end when hit end of script, ruby exits. if add sleep 10 after final loop, can see output show up. (albeit, 3 each time, because binding i reflects value @ end of processing, , sleep causes thread switch loop.) you might want like: threads = [] in 1..3 threads << thread.new { sleep 5 puts } end threads.map {|t| t.join } that wait threads terminate before exiting.

(if don't have single quotes, happens?) in second, it's piped through local shell ssh command , interpreter launched. rather perform convoluted escapes of code come out correctly when crammed through sh, prefer pipe text in through stdin. it's simpler. using ipc::run heavy lifting: #!/usr/bin/env perl use strict; use warnings; use ipc::run qw(run); $in = <<ffff; 2 + 2 8 * (2 + 3) ffff $cmd = [qw(ssh user@host perl calc.pl)]; run $cmd, \$in, \my $out, \

do have plugin/way in eclipse forbids(show error/warning) while using method. in code, want way confirm system.currenttimemillis() / calendar.getinstance() not being called if tries use this, eclipse should show error. thanks ankush you write own findbugs plugin relies on findbugs api provide metadata method invocations (among other opcodes found in bytecode). you'll need implement custom bytecodescanningdetector can verify if operation involves execution of set of banned apis ( system.currenttimemillis() , calendar.getinstance() ) in case. here's tutorial started on writing findbugs plugin. can use plugin in eclipse, preferable run in ci server part of build. you may find other static analysis tools pmd may have same features, exposed using own apis. also, if want run part of build, can delegate these checks sonar, allows easy construction of architectural rules these . note - haven't tried on methods, , i'd warn sonar architectural constraints
