login - Facebook OAuth "An Error Has Occurred" -

i'm having issues getting users logged in oauth dialog. working before today, suspect might in conjunction february breaking changes. see in production @ womstreet.

sandbox mode disabled, url's set in basic setting section developer page in facebook.

i using devise ruby on rails, inspecting url hand seems good.

any ideas on begin debug?

update 1: seems there bug study open on facebook addressing issue: link here

looks facebook got dev community angry 1 time again rolling out changes effect basic login. don't see solution trying login dialog here: https://developers.facebook.com/docs/concepts/login/

bug link: https://developers.facebook.com/bugs/207955409343730

edit: solv need alter url params. change:

app_id to: client_id next to: redirect_uri

so url link should like:

https://www.facebook.com/dialog/oauth?client_id=something&redirect_uri=something

ios - change UIBackgroundModes audio at runtime -

i have app plays music, , want enable background modes. sound category set kaudiosessioncategory_mediaplayback , if add together audio string in uibackgroundmodes within info.plist file keeps playing audio. far good.

now want give alternative users, take if sound plays in background or not. tried getting file , deleting key far nil happens. did (in selector handled uibutton) :

-(void) disablebackgroundaudio:(uibutton*)button{ nsdictionary *plistdict = [[nsbundle mainbundle] infodictionary]; [plistdict setvalue:@"" forkey:@"uibackgroundmodes"]; }

if print value in console, before , after, can see had "audio" before, , after called, blank string. however, if force home button sound playing no matter if disabled audio.

my guess not way update (although i'm not sure if it's possible) info.plist file. possible @ all? after think giving users selection improve specific app, , i've seen other apps doing it.

any help appreciated.

the info.plist part of application's bundle. all files in bundle immutable.

keep audio value there , pause music when application enters background (in case user turned alternative off).

direct3d - Passing colors through a pixel shader in HLSL -

direct3d - Passing colors through a pixel shader in HLSL -

i have have pixel shader should pass input color through, instead getting constant result. think syntax might problem. here shader:

struct pixelshaderinput { float3 color : color; }; struct pixelshaderoutput { float4 color : sv_target0; }; pixelshaderoutput main(pixelshaderinput input) { pixelshaderoutput output; output.color.rgba = float4(input.color, 1.0f); // input.color 0.5, 0.5, 0.5; output black // output.color.rgba = float4(0.5f, 0.5f, 0.5f, 1); // output grayness homecoming output; }

for testing, have vertex shader precedes in pipleline passing color parameter of 0.5, 0.5, 0.5. stepping through pixel shader in visualstudio, input.color has right values, , these beingness assinged output.color correctly. when rendered, vertices utilize shader black.

here vertex shader element description:

const d3d11_input_element_desc vertexdesc[] = { { "position", 0, dxgi_format_r32g32b32_float, 0, d3d11_append_aligned_element, d3d11_input_per_vertex_data, 0 }, { "color", 0, dxgi_format_r32g32b32_float, 0, d3d11_append_aligned_element, d3d11_input_per_vertex_data, 0 }, { "texcoord", 0, dxgi_format_r32g32_float, 0, d3d11_append_aligned_element, d3d11_input_per_vertex_data, 0 }, };

i'm not sure if it's of import vertex shader takes colors rgb outputs same, pixel shader outputs rgba. alpha layer working correctly @ least.

if comment out first assignment, 1 using input.color, , uncomment other assignment, explicit values, rendered pixels grayness (as expected).

any ideas on i'm doing wrong here?

i'm using shader model 4 level 9_1, optimizations disabled , debug info enabled.

output.color.rgba = float4(input.color, 1.0f);

your input.color float4 , passing float4, think should work

output.color.rgba = float4(input.color.rgb, 1.0f);

this need pass thru simply

homecoming input.color;

if want alter colour reddish like

input.color = float4(1.0f, 0.0f, 0.0f, 1.0f); homecoming input.color;

database design - About SQL and complexity -

i've created sql table field x , field date. compute sum of x date < d. i've 2 possibilities :

create new field, "sum of x", represents sum of x when date < date[field] compute sum of x "manually", sql request

is there method superior ? or, if not, assume depends on table size. approximate size equalizes 2 methods ?

thank much.

is there method superior ?

no. in general, stick simplest solution until find doesn't work more. simplest solution in case calculate derived field each time need it.

or, if not, assume depends on table size.

yes. , number of insertions vs. number of reads. , whether dates monotonically increasing or not. , space (memory/disk) vs. time (processing power) tradeoff of scheme , requirements. , number of other things too.

what approximate size equalizes 2 methods ?

how long piece of string? many other variables reply that.

to repeat: stick simple until forced otherwise. maintaining cached values introduces complexity , corner cases: transactional boundaries? happens if add together new row? presumably triggers subsequent transaction observe , update affected rows. happens if roll original transaction?

that's lot more logic. much more potential go wrong. stick yagni until find do.

android - Scaling large bitmap alternative approach -

firstly aware of recommended approach of using injustdecodebounds , insample size load bitmaps @ size close desired size. broad approach gets image approximate target.

i have though of utilising options.indensity , options.intargetdensity trick native loader scaling image more exactly desired target size. set options.indensity actual width of image , options.intargetdensity desired width , indeed image @ desired size (aspect ration happens remain same in case). set image.setdensity(density_none) on resulting image , appears work ok.

anyone know of wrong approach? thoughts on memory efficiency , image quality?

it works on search (1) , (2). how can code accomplish results when doing search (3) , (4) too?

android - Why would my dynamically generated content not show up in tablelayout -

i trying load buttons table layout within fragment. why not show up. see changing background works (changed gray reddish in oncreateview(......)) when phone call loadallbuttons not show up.

public view oncreateview(layoutinflater inflater, viewgroup container, bundle savedinstancestate) { if(container == null) homecoming null; basedview = (tablelayout) inflater.inflate(r.layout.fragment_difficult_sound_syllable, container, false); currentsyllable = getarguments().getstring(staticvalues.difficult_sound_selector); basedview.setbackgroundcolor(color.red); homecoming basedview; }

below loadallbuttons, , before asks yes says loaded (e.g. buttons , rows added, checked via logcat after row.add() , basedview.add())

private void loadallbuttons() { databasehelper tmphelper = new databasehelper(getactivity().getapplicationcontext()); arraylist<buttoninfocontainer> tmparray = null; if(currentsyllable.contentequals(staticvalues.consonant)) { tmparray = tmphelper.returnallconsonants(); log.i(staticvalues.tag, "returned consonants"); } else { tmparray = tmphelper.returnallvowels(); log.i(staticvalues.tag, "returned vowels"); } if(tmparray != null) { tablerow row = null; infobutton tmpbutton = null; //layoutparams rowparams = new layoutparams(layoutparams.wrap_content, layoutparams.wrap_content); //tablerow.layoutparams equalparams = new tablerow.layoutparams(layoutparams.wrap_content, layoutparams.wrap_content, 0); linearlayout.layoutparams buttonlayout = new linearlayout.layoutparams(layoutparams.fill_parent, layoutparams.fill_parent); if(basedview != null) { for(int = 0; < tmparray.size(); i++) { //adds new row table if modulus 0 if(( % 2 ) == 0) { row = (tablerow) getlayoutinflater(getarguments()).inflate(r.layout.table_row, null); //row.setlayoutparams(rowparams); basedview.addview(row); } tmpbutton = (infobutton) getlayoutinflater(getarguments()).inflate(r.layout.info_button, null); tmpbutton.setbackgroundresource(r.drawable.button_bg); tmpbutton.setlayoutparams(buttonlayout); //set button text tmpbutton.settext(tmparray.get(i).buttontext); //obtain held info tmpbutton.setextrainfo(tmparray.get(i).infoheld); //tmpbutton.setwidth(buttonwidth); //tmpbutton.setheight(buttonheight); //tmpbutton.settextsize(typedvalue.complex_unit_dip, textsize); tmpbutton.settextcolor(getresources().getcolor(r.color.button_text_color)); tmpbutton.settypeface(typeface.default_bold); row.addview(tmpbutton); tmpbutton.setonclicklistener(listenerdynamicbutton); } } } }

for reason though logcat outputs show (buttons showing proper names right amount of buttons) table layout not populated.

figured out reply in regards own problem. after

tmpbutton = (infobutton) getlayoutinflter()...

to

row.addview(tmpbutton);

had deleted except

tmpbutton.settext();

and

tmpbutton.setextrainfo(..);

although not know why killed layout. if figures part out gladly take answer.

i using sql server express 2008

when i'm trying load info txt file in table

create table clients ( clientid int not null identity (9000,1), lastname varchar (30)not null, firsname varchar (30)not null, midinitial varchar (3), dob date not null, adress varchar (40) not null, adress2 varchar (10), city varchar (40) not null, zip int not null, phone varchar (30) , categcode varchar (2) not null, statusid int not null, hispanic binary default 0, ethncode varchar(3) , langid int, clientproxy varchar (200), parent varchar (40), hshldsize int default 1, annualhshldincome int, monthlyyearly varchar(7) , pfds int, wic binary default 0, medicaid binary default 0, atap binary default 0, foodstamps binary default 0, agencyid int not null, routid int , deliverynotes varchar (200), recertificationdate date not null, notes text, primary key (clientid) );

i utilize

set identity_insert clients2 on; mass insert clients2 'c:\sample_clients.txt' ( fieldterminator = ',', rowterminator = '\r\n' )

sql server express trows me errors

msg 545, level 16, state 1, line 2 explicit value must specified identity column in table 'clients' either when identity_insert set on or when replication user inserting not replication identity column.

file has 1 line (for sample data) check many times 1 line

data looks

any ideas how prepare problem?

you need parameter keepidentity in mass insert statement. required retain identity values in load.

bulk insert clients2 'c:\sample_clients.txt' ( keepidentity, fieldterminator = ',', rowterminator = '\r\n' )

i think have problem because have no info or placeholder notes column. comma added end of file should address this.

Reinstaling Formula One component (TF1Book) in Delphi 2007, License Information for TF1Book not found error -

i'm moving old project developed delphi 2007 , bunch of 3rd party components old computer own instalation. except tf1book component (from vcf132.ocx library, version 4.1.1.2) works fine. i'm using exact same version of delphi in new computer , same patches. (the older computer belongs developer left company , it's unavailable , unreachable)

the error i'm getting in design time, , in design time is:

license info tf1book not found. cannot utilize command in design mode.

so, can still compile , can edit .dfm form in notepad , works fine, in runtime, can't work within delphi.

please, note have read first 30 entrys each google search related problem, several variations. , of them says should run regsvr32 register ocx within windows , solve problem. also, of posts or blogs i've found way older, , they're talking version 3.x of component. using 4.1.1.2 version. other developer had in computer.

i repeated supposed procedure of placing vcf132.ocx on \windows\system32 or windows\syswow64 (for x64 windows) , run appropriate regsvr32 version register component in 3 computers: win 7 x86, win 7 x64, win 8 , winxp sp3 , got same result in of them.

i'm starting think real licensing issue, not ocx windows registering issues. actually, if don't register de ocx in windows error in delphi different, class not found or similar.

nobody else in company (a little 3 guys company) knows or remember how component acquired , hence can't find proper installer components.

though, researching windows registry in computer found info sort of registration process, user, company , serial number. there no ".lic" files associated ocx in old computer.

but far, i'm unable find such installer in computer. happy acquire new license, product not beingness sold anymore.

so, question. vcf132.ocx, version 4.1.1.2, knows/remember if there re-create protection or registration mechanisms forbid me move component other computer?

i used utilize component way when. recall, registering ocx gives runtime support. working @ designtime need run, on dev machine, installation programme vendor supplied.

i distinctly remember there .lic file installed onto each developer machine. should find them on old machines, i'm not sure whether can transferred.

Overflowing a stack in theory.. and assembly -

Overflowing a stack in theory.. and assembly -

assuming x86 scheme no aslr i'd inquire following;

1) theory says when execute stack overflow attack, value pointed ebp register overwritten new homecoming address too.

now, since never go caller function don't need ebp's original value restore previous stack frame nevertheless, ebp register must point somewhere @ times. how ebp set after eip register starts pointing our new shellcode? more specifically, of 2 assembly instructions (leave-ret) induces farther microinstruction restores ebp value?

2) lastly not least, inquire how create sure in occasions our shellcode needs force couple of values on stack, these values won't overwrite part of shellcode? in other words, how can shellcode generated variables placed before start of shellcode , instance not somewhere in between?

thank in advance.

in reply part 2 of question: depending on syscall making, may have set value esp (as arg array). if that's end of shellcode fine. however, if there more shell code , happen push and esp happens point somewhere in rest of shellcode might in problem (because @ point writing on own instructions). simple prepare sub $0x99, %esp @ origin of shellcode.

edit (in response comments)

perhaps misunderstood question. when said 'stack overflow' assumed meant buffer overflow. if assumed correctly read on. assuming talking classic smashing-the-stack sort of exploit (which seems case based on image linked to), filling buffer nop sled, shellcode , overwriting homecoming pointer. shell code "position independent code". means series of instructions can executed regardless of current state of registers, flags etc.

normally, (this way link posted depicts it) fill buffer nops, followed shellcode, , homecoming address points somewhere in tho nop sled. when ret instruction executed, address in %esp poped %eip , %esp incremented 4 (in x86). problem if shellcode has several push instructions, has side effect of decrementing %esp. if have plenty of them and shellcode way @ end (i.e. adjacent homecoming address) may end overwriting shellcode push instructions.

so, reply question. no, there no 'mechanism' separate shellcode 'its stack'. because there no stack per-se shellcode. remember, position independent code. must able run regardless of machine state. stack management needs happen must performed shellcode itself. why suggested sub $0x99, %esp @ begning of shellcode if have many push statements in code. alternative create sure there sufficient space between homecoming address (which %esp-4 pointing at) , shellcode.

template:

{{ animal.name }} {{ animal.photo.all }}

but not working.

models:

class animal(models.model): name = models.charfield(max_length=255) class photo(models.model): photo = models.imagefield(upload_to='media/images') animal = models.foreignkey(animal)

you need read documentation on following relationships see how access related items.

in case, each animal has photo_set way list of photo objects belonging animal.

in template, do:

i have process running root needs spin threads off run various users. part working fine, need way communicate between kid processes , parent process.

when seek using multiprocessing.manager() lists, dictionary, lock, queue, etc, has permission denied errors on process has lowered permissions.

is there way grant access user or pid prepare this?

basic code represents i'm running (run root):

#!/usr/bin/env python import multiprocessing, os manager = multiprocessing.manager() problematic_list = manager.list() os.setuid(43121) # or whatever user problematic_list.append('anything')

result:

the first exception appears 1 of import here.

python (at to the lowest degree 2.6) uses unix socket communicate appears so:

performance - Meteor users and backbone very slow -

i created project easy content sharing. can @ project here: sharingproject

you can utilize user@example.com 123456 password test site verified user. of course of study site has bugs yet...

i used meteor user bundle , backbone bundle navigate through pages. on localhost, there no problem. testing uploaded project meteor server. while logged in , navigating through pages, every time navigate new page app 'checks' user on client side because of url change. annoying...

of course of study navigate through pages calling session.set('page_id', ..) goal able send people url specific page on server.

the code similar 1 in todos illustration meteor page:

meteor.subscribe('pages', function () { if (!session.get('page_id')) { var page = pages.findone({}, {sort: {owner: -1}}); if (page) router.setpage(page._id); } }); ... var pagesrouter = backbone.router.extend({ routes: { ":page_id": "main" }, main: function (page_id) { session.set("page_id", page_id); }, setpage: function (page_id) { this.navigate(page_id, true); } }); router = new pagesrouter; meteor.startup(function () { backbone.history.start({pushstate: true}); });

why asking here: searched web , can't find same problem. either nobody tried before or there simple solution this?

edit: how phone call pages

<template name="pages"> {{#each pages}} <p><a href="/{{_id}}">{{title}}</a> {{#if isauthor}} <a class="delpage" href="javascript:delpage('{{_id}}')">delete</a> {{/if}} </p> {{/each}} </template>

i don't know how rendering page links link :

i need utilize soil lib @ project.

i've included @ source files director soil.h , libsoil.a (renamed libsoil.lib).

i've added header file headers existing item , include header file in header file need it.

i've tried: project properties > linker > input > additional dependencies , @ dropdown menu clicked on "< edit.. >" , typed libsoil.lib.

but getting these errors:

look below (updated errors)

what should do?

edit #1:

this doing:

#include "gl/glut.h" #include "soil.h"

i have both files @ source directory.

without code written soil build succeeds.

with code:

/* load image file straight new opengl texture */ gluint grass_texture = soil_load_ogl_texture ( "original.bmp", soil_load_auto, soil_create_new_id, soil_flag_mipmaps | soil_flag_invert_y | soil_flag_ntsc_safe_rgb | soil_flag_compress_to_dxt ); /* check error during load process */ if( 0 == grass_texture ) { printf( "soil loading error: '%s'\n", soil_last_result() ); }

svn - Erase a Subversion Branch -

svn - Erase a Subversion Branch -

i assigned merge few branches trunk in subversion. project setup following.

trunk branches brancha branchb branchc tags // bunch of tags (1 per release)

the goal integrate brancha , branchb trunk , have them "hidden" somehow.

i think know how actual merge. right click trunk in windows explorer , tortoisesvn > merge... reintegrate branch, take branch, merge.

question 1 - right method use?

i unsure repository after this. want create sure no future developers mistakenly work on old branches.

question 2 - branch unworkable after merge, or need else? can "delete" branch? if so, happen branch history? or need hacky apply locks branch?

thanks help.

question 1 - right method use?

yes, merge contents of branch working directory. nil happen repository until commit (newly merged) trunk. 1 time commit not trunk changes in repo, remember merged in branch.

question 2 - branch unworkable after merge, or need else?

at point can delete branch or can maintain making changes branch. if maintain making changes branch , later merge, new stuff (not stuff merged) merged trunk.

if want delete branch, easiest way i've found open repo browser, right-click on branch , select "delete". branch disappear latest version. still in repo history , can bring if necessary, doing fresh checkout not see it.

so i'm using yaml configuration files , py yaml parse it. 1 field have like:

host: hostname\server,5858

but when gets parsed here get:

{ "host": "hostname\\server,5858" }

with 2 backslashes. tried every combination of single quotes, double quotes, etc. what's best way parse correctly ? thanks

len("\\") == 1. see representation of string python string literal. backslash has special meaning in python literal e.g., "\n" single character (a newline). literal backslash in string, should escaped "\\".

c# - When passing a managed byte[] array through PInvoke to be filled in by Win32, does it need to be pinned? -

c# - When passing a managed byte[] array through PInvoke to be filled in by Win32, does it need to be pinned? -

suppose you're calling win32 function fill in byte array. create array of size 32, empty. pass in win32 function filled int, , utilize later in managed code. there exist chance byte array might moved or overwritten in between time allocated , filled in win32 function?

short answer: no, pinning not necessary in case

longer answer:

the clr automatically pin references managed objects when cross pinvoke boundary. pinvoke function exits reference unpinned. in situations having native function fill byte[] no manually pinning necessary because object used native code during function call.

manually pinning of array becomes necessary if native code caches managed pointer. when happens must manually pin array until native code no longer needs pointer. in case presume pointer not cached hence it's not necessary pin

postgresql - Do I have to create a surrogate key if I want to save space? -

postgresql - Do I have to create a surrogate key if I want to save space? -

let's have big table owners of cars so:

ownership owner | auto --------------- steven | audi bernahrd | vw dieter | vw eike | vw robert | audi ... 1 hundred 1000000 rows ...

if refactor this:

ownership owner | auto <-foreign key type.car_type --------------- steven | audi bernahrd | vw dieter | vw eike | vw robert | audi ... type car_type | --------------- audi vw

do win spacewise or speedwise or need create integer surrogate key on car_type that?

using 2 tables , string foreign key of course of study utilize more space using one. how much more depends on how many types of cars have.

you should utilize integer car_id:

using integer keys save space if important percentage of auto names repeat.

more if you'd need index car column, integer index much smaller string index.

also comparing integers faster comparing strings, searching auto should faster.

smaller table means bigger part if fit in cache, accessing should faster.

database - What do scale and precision mean when specifying a decimal field type in Doctrine 2? -

database - What do scale and precision mean when specifying a decimal field type in Doctrine 2? -

i'm creating decimal field hold financial figure in doctrine2 symfony2 application.

currently, looks this:

/** * @orm\column(type="decimal") */ protected $rate;

when entered value , said value persisted database, rounded integer. i'm guessing need set precision , scale types field, need explain do?

the doctrine2 documentation says:

precision: precision decimal (exact numeric) column (applies decimal column)

scale: scale decimal (exact numeric) column (applies decimal column)

but doesn't tell me awful lot.

i'm guessing precision number of decimal places round to, assume should 2, scale? scale important figures?

should field declaration this? :-

/** * @orm\column(type="decimal", precision=2, scale=4) */ protected $rate;

doctrine uses types similar sql types. decimal happens fixed precision type (unlike floats).

taken mysql documentation:

in decimal column declaration, precision , scale can (and is) specified; example:

salary decimal(5,2)

in example, 5 precision , 2 scale. precision represents number of important digits stored values, , scale represents number of digits can stored next decimal point.

standard sql requires decimal(5,2) able store value 5 digits , 2 decimals, values can stored in salary column range -999.99 999.99.

constructor - PHP: Can I pass $this in the _constructor? -

i pass php object in own constructor object this:

class foo { $parent_object; public function __construct($obj) { $this->parent_object = $obj; } } class bar { public function __construct() { $blub = new foo($this); } }

the question asking myself is: can pass $this in constructor of bar, because object has not been created... $this valid reference whole object?

sure can. maintain in mind $this points current object though. in:

$blub = new foo($this);

$this points instance of bar. $obj in constructor of foo instance of bar.

$this available @ origin of constructor. if bar calls functions on $obj might instance of bar not yet in right state (ie. $blub has not been assigned). lead reference issues, solution move reference exchange out of constructor.

ruby on rails - Backbone application: storing user settings -

i have been working on rails/backbone application. until now, time user made specific changes application (e.g. chose 1 view on others, used filters, customized info presented in view), store his/her choices rails session variables. using info these session variables ensured user's changes persist when page refreshes or when new instances of application used on same computer. case until user signs out, leads loss of session variables' info , default settings next time user logs in.

the received feedback users want changes persist if log out or if utilize different computers (e.g. default settings should replaced changes, long same user logged in). how should implement feature?

thank you!

agreed mischa, should save datas in database.

this exemple how simple add together preferences user:

class user < activerecord::base serialize :preferences end u = user.new u.preferences = { :view => {:controller => :dasboard, :action => :index}, :filters => { :users => { :order => :email :page => 1 :quantity_per_page => 20 } } }

in jquery template in project, trying write out variable html string without encoding html. when output variable so:

${description}

it results in raw html string beingness outputted tags , so:

<p>text <b>bold</b> <i>italic</i></p>

but when seek turn markup real tags @ same exact place in code:

{{html $description}}

doesn't output anything!

i tried zillion ways of passing in variable, think there's going on in html routine i'm not getting.

thanks.

update:

here's how it's beingness called:

this.$el.attr('data-id', tmpldata.id). data('id', tmpldata.id).html($.tmpl(this.template, tmpldata));

where this.template template file , tmpldata json includes $description , other variables needed.

another update:

{{html '<p>string</p>'}}

does behave expected.

{{html $another_variable}}

fails produce output when $another_variable doesn't have html in it.

another update:

i tried:

${$item.html(description)}

and changed phone call template

this.$el.attr('data-id', tmpldata.id). data('id', tmpldata.id). html($.tmpl(this.template, tmpldata, { truncate: _.truncatestrip, html: _.html, }));

and wrote custom html routine pass through string unchanged recommended:

html: function(str) { homecoming str; }

but still no dice.

the reply is:

{{html description}}

i tried on, because left stray spaces within curly brackets, did not interpret properly.

ios - performSegueWithIdentifier:sender not working on device -

i have storyboard has viewcontroller defaultviewcontroller neither uitabbarcontroller nor 'uinavigationcontroller`. decides whether upcoming controller should registration screen or home screen.

i have 2 segues originating it, 1 pointing uinavigationcontroller' registration while other moves 'uitabbarcontroller default home screen.

the defaultviewcontroller calls next in viewdidappear: method

nsstring *thecontroller = nil; if ([appstate sharedappstate].currentuserstate == registered) { thecontroller = @"homesegue"; } else { thecontroller = @"regsegue"; } [self performseguewithidentifier:thecontroller sender:self];

the segue performed on ios simulator 5.1.1 6.0. however, nil happens when run code on iphone ios 5.1.1 or iphone ios 6.0. view stays defaultviewcontrollers view.

edit created whole new project , works fine there when copied old storyboard contents , classes, issue re-appears.. !!

** edit 2 ** removed rootviewcontroller associated uinavigationcontroller , added simple uiviewcontroller label on , works fine. if add together custom registrationcontroller root controller, segue not performed.

p.s. custom registrationcontroller adds controller childviewcontroller in it.

strange .. very strage.. how got work.

the registrationcontroller part of navigationcontroller, created instance of reginfocontroller added both it's subview kid controller.

i overrid awakefromnib method of childcontroller , started working.

to confirm scenario, removed method , stopped working..

hibernate - JPA merge() best practise -

hibernate - JPA merge() best practise -

i implemented service entity object , uses pure jpa, used spring, in spring xml config configured hibernate jpa impl. using spring info crud operations. in our scheme our entity object beingness pulled/updated many times , there high contention(concurrency) data. our code in many places many classes inject service bean , phone call getentity method entity, after alter entity(which detached understanding, in same thread em object should same per knowledge) takes while entity comes service updated, phone call save() method of service save entity. save() method nil calls merge() crud operation. transactional @transactional annotation. here problem arises, when pulls entity object , while changing else might pull , alter , save back, entity read dirty , if save it, override updated entity. problem here changing entity outside of service , calling save back. here spring info repository classes dao layer.

optimistic lock 1 solution did not reasons, not work us. thinking pessimistic lock. example, when entity update locking, alter somewhere else in different place , phone call back(the entity locked against update!) work? not sure if still entitymanager object there used pulling entity. if there takes quite long time pass 'smart' logics before gets updated , unlocks it.

here simple illustration code scenario:

class someentity { long id; string field1; string field2; string field3; string field4; string field5; string field6; string field7; //getters , setters, column annotations } class someentityserviceimple implemenet someentityservice{ @transactional save(someentity se){ //call spring data's merge() method } get(long id){ //call spring data's findone() } } //this class might spring bean, might not be. if not someentityservice bean shared appcontext class somecrazyclass{ @autowired someentityservice service; somemethod(){ someentity e = service.get(1l); //do tons of logic here, alter entity object, phone call methods , again, takes 3 seond service.save(e); //probably detached , updated object, overriding it. } } }

here cannot move tons of logic within service layer, quite specific , kind of different logics in 100s of places.

so there way come around , @ to the lowest degree apply pessimistic lock situation?

thanks reading , answering .

for pessimistic locking, can seek below code

locking while fetching entity

entitymanager.find(entity.class, pk, lockmodetype.pessimistic_write);

applying lock afterwards

entitymanager.lock(entity, lockmodetype.pessimistic_write);

setting lock mode in query

query.setlockmode(lockmodetype.pessimistic_write);

else, can seek adding synchronized method in someentityserviceimpl.

public synchronized void saveentity(e){ { object o = get(id); //-- fetch recent entity applychanges(o, e); //-- applying custom changes save(o); //-- persisting entity }

therefore, don't have move logic within service, delegate database operations. also, mutual place code alterations without affecting application logic.

github - Git workflow (commit/push/ & create pull request) -

github - Git workflow (commit/push/ & create pull request) -

i have created branch master, made changes , ready commit , force remote master.

do first need commit changes local branch

git commit -m "new changes, etc."

then

git force

to force remote?

is first part correct?

then how create pull request?

before anything, should aware perform pull request, have work in branch separate desired branch. branches super lightweight in git, , should utilize them time. create , switch on new branch, first git branch <new branch name>, , check out using git checkout <new branch name>. new branch created based on current branch (so if going create new 1 want based on master, create sure switch master first).

to commit, need first add together files you'd commit staging area. git add together <filename>. if you'd add together files see when calling git status, can git add together ..

next can commit. prefer not add together message on command-line big changes, because have 1 screen showing me that's getting committed , isn't. think default editor vi, if don't sense comfortable vi, can specify editor through git config --global core.editor <your favorite editor>.

you're ready force github! it! git push

now you're ready set pull request. head github , find repo. nail pull request button. have 2 of import drop downs now. box on left target branch. box on right source branch. set left master, , right new branch. add together comment, review everything, nail send pull request. ba-bam.

when made @xmlelement instead of attribute, schema generated no issues, must have that. ideas?

the nullpointerexception seeing appears due bug in jaxb reference implementation. can come in bug using next link.

http://java.net/jira/browse/jaxb/

a similar exception not occur when using eclipselink jaxb (moxy) jaxb provider.

workaround

you alter property of type string instead. property of type object not round trip anyways unlike elements, attributes not have mechanisms include typing information.

when made @xmlelement instead of attribute, schema generated no issues, must have that.

java model (root)

object valid property type when mapped xml element.

import javax.xml.bind.annotation.xmlrootelement; @xmlrootelement public class root { private object settingvalue; public object getsettingvalue() { homecoming settingvalue; } public void setsettingvalue(final object settingvalue) { this.settingvalue = settingvalue; } }

this because xml element can contain typing info in form of xsi:type attribute.

class="lang-xml prettyprint-override"><?xml version="1.0" encoding="utf-8" standalone="yes"?> <root> <settingvalue xmlns:xsi="http://www.w3.org/2001/xmlschema-instance" xmlns:xs="http://www.w3.org/2001/xmlschema" xsi:type="xs:int">123</settingvalue> </root>

Delphi - Detect pressing 3 keys at the same time -

i want observe pressing 3 keys in form illustration ctrl+c+n...the typed form need observe begin ctrl , next come 2 letters.

how ?

on arrival of 1 of keys, can if other key has been down. e.g.:

procedure tform1.formkeydown(sender: tobject; var key: word; shift: tshiftstate); begin if shift = [ssctrl] begin case key of ord('c'): if (getkeystate(ord('n')) , $80) = $80 showmessage('combo'); ord('n'): if (getkeystate(ord('c')) , $80) = $80 showmessage('combo'); end; end; end;

however observe instance n+ctrl+c, sequence not begin ctrl key. if doesn't qualify valid key combination, can maintain bit of key history help of flag. next should observe sequences begins ctrl:

type tform1 = class(tform) procedure formkeydown(sender: tobject; var key: word; shift: tshiftstate); procedure formkeyup(sender: tobject; var key: word; shift: tshiftstate); private fvalidkeycombo: boolean; end; ... procedure tform1.formkeydown(sender: tobject; var key: word; shift: tshiftstate); begin if fvalidkeycombo , (shift = [ssctrl]) case key of ord('c'): if (getkeystate(ord('n')) , $80) = $80 showmessage('combo'); ord('n'): if (getkeystate(ord('c')) , $80) = $80 showmessage('combo'); end; fvalidkeycombo := (shift = [ssctrl]) , (key in [ord('c'), ord('n')]); end; procedure tform1.formkeyup(sender: tobject; var key: word; shift: tshiftstate); begin fvalidkeycombo := false; end;

html - Cannot identify strange space between links in horizontal menu -

i'm creating simple horizontal menu. when hover item changes background color, lefts unusual 3px space on left side of link, , cannot identify why shows up, , how remove it.

menu here: http://pokerzysta.site44.com/ (linki, posty, forum, dodaj) thought what's wrong it?

thats because you're displaying list in horizontal manner display: inline-block;. rendered there white spaces html markup (most line-breaks after li-tags).

if set li-tags in html without white-space , line-breaks won't happen:

<ul id="main-menu" class="horizontal-list fleft"> <li><a href="#">linki</a></li><li><a href="#">posty</a></li><li><a href="#">forum</a></li><li><a href="#">dodaj</a><li> </ul>

oncreate()...

// sharedpreferences sharedpreferences = this.getsharedpreferences(shared_preferences, context.mode_private);

attempting either way ensure savedusernames initialized something.

// if usernames saved, initialize savedusernames them or else initiliaze blank ready if (sharedpreferences.contains(saved_names)) { getsavedusernames(); } else { savedusernames = new arraylist<string>(); }

button listener saves current displayed username savedusernames arraylist

vba - How to select some selected Pivot table area? -

i trying select , re-create selected area of pivot table. able determine amount of area want , able display range in message box not objective. want re-create selected range. code looks this. want re-create values in range (toprow1,leftcoloumn:lastrow,rightcoloumn). fyi message box code don't need tell range no.

sub pivottablerangeareas() activesheet.pivottables(1) dim toprow1 long, toprow2 long, lastrow long dim leftcolumn long, rightcolumn long toprow2 = .tablerange2.row .tablerange1 toprow1 = .row lastrow = .rows.count + .row - 1 leftcolumn = .column rightcolumn = .columns.count + .column - 1 end msgbox "the pivot table named " & .name & vbcrlf & _ "occupies these range elements:" & vbcrlf & vbcrlf & _ "with study (page) field: " & vbcrlf & _ .tablerange2.address(0, 0) & vbcrlf & _ "without study (page) field: " & vbcrlf & _ .tablerange1.address(0, 0) & vbcrlf & vbcrlf & _ "first row, study (page) field: " & toprow2 & vbcrlf & _ "first row, without study (page) field: " & toprow1 & vbcrlf & _ "last row: " & lastrow & vbcrlf & _ "left column: " & leftcolumn & vbcrlf & _ "right column: " & rightcolumn, , "pivot table location." end end sub

i'm guessing it's values want copy? if so, seek starting - it'll set values sheet2 starting @ range a1. i'm not sure range pivot table want re-create - you'll have alter of suit:

sub copyrange() dim varray() variant 'copies values between (toprow1, leftcolumn) , (lastrow, rightcolumn) array varray = activesheet.range(cells(toprow1, leftcolumn), cells(lastrow, rightcolumn)).value 'pastes values array sheet2, starting @ a1 sheet2.range("a1").resize(ubound(varray, 1), ubound(varray, 2)).value = varray end sub
