i'm trying "notes" single contact. added fine retrieving has been problem. string selection = contactscontract.commondatakinds.phone.display_name+" like'%" + sender +"%'"; string[] projection = new string[] { contactscontract.commondatakinds.note.note}; cursor c2 = getcontentresolver().query(contactscontract.data.content_uri, projection, selection, null, null); if (c2.movetofirst()) { notes = c2.getstring(0); } it works fine other values name or phone number can't seem notes retrieve correctly. retrieves random value email instead. i believe problem not rows in table represent contact types have notes. have request proper mime type. contactscontract.commondatakinds.note alias 'data1' column present on rows, when row of different mime type, represents different data. how contacts in android should give idea of how this.

currently i'm designing hashing system user emails, happens if user email longer hash output. use sha1 sha256 or sha512 if makes difference based on algorithm... seems @ point algorithm wouldn't able keep on producing unique outputs. hash values have fixed length 13 (des) 86 (sha2) characters. it's normal if give longer input. think of "cross sum" can arbitrary long numbers well. regarding uniqueness, using standard crypt(3) function sha-512 , characters in set a-za-z./ have 54 different characters , 86 character long string 54^86 different values. that's lot :-) (don't use 13 char long des crypt though, that's bruteforceable modern hardware , use "salt" values same input string gives different hash values , can't use "rainbow table" attack).

hi new in , trying use list_for_each_entry iterate on list. looks this list_for_each_entry(pos, head, member){ if (something == pos.x) //reset loop cursor starts iterating on again } how perform commented part without using goto? 1 more thing, safe use break/continue inside list_for_each_entry or there functions available achieve this? thanks. look @ definition of list_for_each_entry #define list_for_each_entry(pos, head, member) \ (pos = list_entry((head)->next, typeof(*pos), member); \ &pos->member != (head); \ pos = list_entry(pos->member.next, typeof(*pos), member)) from https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/include/linux/list.h?id=refs/tags/v3.10-rc2#n418 as see defined simple loop, no black magic here, can use continue/break. for other question, guess depends how why you're trying that. simplest way do: int iterateagain = 0; list_for_each_entry(pos, head, member) { ...

why java disallow inheritance class constructor private? java doesn't prevent sub-classing of class private constructors. public class main { static class { private a() { system.out.println("subclassed in "+getclass().getname()); } } static class b extends { public b() { } } public static void main(string... ignored) { new b(); } } prints subclassed in main$b what prevents sub-classes cannot access constructors of super class. means private constructor cannot used in class file, , package local constructor cannot used in package. in situation, option have delegation. need call factory method create instance of "super" class , wrap it.

i working on project involves card swiping on different types of swipers different vendors. these swipers have own static libraries. had no issues in integrating these libraries in project i.e. fine @ compile time, @ runtime start behaving unexpectedly. due fact these libraries have common entry point, going wrong , apis getting called when should not be. all can think of resolve issue lazy loading library. possible in ios because know lazy loading dynamic libraries. if possible how? or there other way solve issue?

i have asp.net page using ef 4, it has couple of tables linked using inheritance relationship. locally when running on asp.net development server works fine, when deploy iis (windows server 2003) i'm getting error: the resulttype of specified expression not compatible required type. expression resulttype 'transient.reference[a]' required type 'transient.reference[b]' where : b i have found https://connect.microsoft.com/visualstudio/feedback/details/544639/ef4-inheritance-defined-using-queryview-doesnt-work-properly-with-association but doesn't explain why works on development server (though have .net 4.5 installed, development server says it's running on 4.0) , why class/table has problem. i have other tables have same kind of relationships , code works fine. i can't paste code, in ef i'm doing like: var bs = repository.a.oftype<b>().include(..).tolist();

i've installed pytables under windows 7 64 bit , passes tests. both python command prompt , idle can see stringcol class, , python console in eclipse can see it. however, pydev's autocomplete can't discover class, , editor keeps displaying error says undefined variable: stringcol despite error, following code runs in eclipse, using pydev from tables import * if __name__ == '__main__': = stringcol(34) print (a) i've switched workspaces, created projects scratch, deleted pyc contains class. nothing seems help. how make pydev recognize class sitting supposed to? have configured "forced builtins" in interpreter. getting-started guide: additionally, may add other libraries want treat builtins, such os, wxpython, opengl, etc. important, because pydev works on java side static information, modules don't have information when analyzed statically, so, pydev creates shell information on those.

i have user model validations behind it. what i'd have signup form on every page of app, static ones. i figured best way through helper methods in application_helpers.rb , works fine, validations don't seem work. i can serve form through iframe, seems bit hacky. i'm using partials now, client side validation (github.com/bcardarella/client_side_validations) works on /new page, not application page. what's best practice in case? one of basic solutions use partial. benefit is: it's built in, it's simple. downside is: you'll busy feed session details proper rendering. another solution use cells kind of case. cells works lightweight controller can controller can do, , it's independent on controller. 1 use case of cells shopping cart, , login form use case in opinion.

i have corpus(held in jserial datastore) of thousands of documents annotations. need divide 3 smaller ones, random picking. easiest way in gate? a piece of running code or detailed guide welcomed! i use groovy console (load "groovy" plugin, start console tools menu). the following code assumes that you have opened datastore in gate developer you have loaded source corpus, , name "fullcorpus" you have created 3 (or many need) other empty corpora and saved them (empty) same datastore . these receive partitions you have no other corpora open in gate developer apart these four you have no documents open then can run following in groovy console: def rnd = new random() def fullcorpus = corpora.find { it.name == 'fullcorpus' } def parts = corpora.findall {it.name != 'fullcorpus' } fullcorpus.each { doc -> def targetcorpus = parts[rnd.nextint(parts.size())] targetcorpus.add(doc) targetcorpus.unloaddocument(doc) } ret...

i have 2 tables: menu ->id_menu ->title ->page_id ->order pages ->id_page ->title ->page ->slug this select function: public function get_all_menu() { return $this->db ->select('menu.*, pages.id_page, pages.title page_title') ->from($this->table) ->join('pages','id_page = page_id') ->order_by($this->order_by) ->get() ->result_array(); } here problem - item in menu can connected page, can solo (without connection page). means page_id in menu table can 0. if page_id 0, not getting row above query. how can items in menu (those connected , not connected page )? as requested comments: you need use "left join" retrieve partial or incomplete values tables. in case, regular join looking matches between 2 tables. since there's no id 0 in 1 of tables, match can't retrieved , row won't selected. using left j...

i have following javascript code: b = document.getelementsbyclassname('name1'); c = document.getelementsbyclassname('name2'); if (b.length != 0) { document.getelementbytagname('body')[0].innerhtml = b[0].innerhtml else if (c.length != 0) { document.getelementbytagname('body')[0].innerhtml = c[0].innerhtml } else document.getelementbytagname('body')[0].innerhtml = 'error'; but not getting desired rendering. whole page renders when divs class name name1 , name2 present. what doing wrong? you skipped closing } bracket in if statement; there no getelementbytagname method in native javascript; you'd better use document.body instead. here bit more correct code: var b = document.getelementsbyclassname("name1"), c = document.getelementsbyclassname("name2"); if (b.length > 0) { document.body.innerhtml = b[0].innerhtml; } else if (c.length > 0) { document.body.innerh...
