i boost because things don't need compiled, included. vast majority of bgl not compiled read_graphviz functionality needs built. seems of other compiled libraries in boost need more information hardware. why read_graphvis need compiled on machine? parsing graph format seems tackled in header include file similar rest of bgl.

so have php project , when i'm running tests class testcase isn't found , can't figure out why. error in question this: fatal error: class 'project\tests\api\testcase' not found in /some/path/here/test/project/tests/api/userstest.php on line 6 the below file named userstest.php , testcase class can't found. <?php namespace project\tests\api; class userstest extends testcase { // code here } the below file testcase.php exists in same folder userstest.php <?php namespace project\tests\api; abstract class testcase extends \phpunit_framework_testcase { abstract protected function getapiclass(); protected function getapimock() { // code here } } both of these files exists in folder structure test/project/tests/api/ . understanding userstest.php should able find class because both of these files exist in same namespace. in test/project have bootstrap.php file looks this. <?php function includeifexist

i reading article explaining how hide files in jpeg pictures . i wondering how it's possible file contain both jpeg data , rar file without visible distortion either image or compressed file. my guess has how either compressed file or jpeg file represented in binary form, have no idea how works. can elaborate on that? all doing adding archive end of jpeg stream. hope jpeg decoder not read past eoi marker, find data there, , wrong. a jpeg image stream of bytes starting soi marker , ending eoi marker. zip , rar streams of byte. zip stream starts 50 4b. rar stream starts 52 61 72 21 1a 07. the method described in link above takes binary copy of (multiple) jpeg stream , appends zip or rar stream it. the rar/zip decoders scan stream until find signature rar or zip (ignoring jpeg stream).

i have been attempting automate installation of 1 of applications have run few roadblocks , need help. currently using dell's kace technology push installer local machines. installer run system user meaning not , can not have direct access network shares (relevant later). the application installation workflow follows: stop local security services allow software install remove mapped drive letter x map network drive x \test\test testapp.exe /s msiexec /i test.msi /quiet start local security services allow software install copy shortcut file desktop the installation has 1 executable , 1 msi have run. exe installs mainframe application. msi file installs few files locally , registers 6 dll files located on mapped drive. this issue comes in - because files must on share drive , installer running system -> system account account can't access mapped drive register files installation fails. i further limited fact can't store username/password in plaintext in batch

so have reviewed link solve problem, referenced below. team build error: path mapped workspace but problem every time queue build definition same problem. ok, go delete tfs workspace it's complaining about. great works! run build again... ok doesn't , have go delete tfs service workspace on again. how come tfs build service stepping on every time build. error " unable create workspace 'xxx' due mapping conflict... path xxx mapped in workspace 'xxx'" mapping workspace previous build created. not specific user. ok, seemed occur because (i hadn't noticed) changed "build agent folder" specification accident fixed path. rather keeping $(sourcedir). changed entry in build definition , worked fine, after multiple builds using same build definition.

what getconfigdata ? , diff between getconfigdata , getstoreconfigdata in magento. $this->getconfigdata('shippingspecificcountry', $store_id); i tried current store id , 0, both gives empty array. can explain above method. your question use little more context -- lacking that. the mage::getstoreconfig method static method on global mage class, , provides access configuration values stored in magento's configuration tree. magento's configuration tree created loading xml files in app/etc/*.xml loading xml files `app/etc/modules/*.xml' merging config.xml files active modules merging in values set in core_config_data (via system -> configuration in admin) because magento's configuration big, many module developers add methods getconfigdata or getconfig make fetching specific configuration values easy. example, consider oversimplified example mage::getstoreconfig('foo/baz/bar') vs. $this->getconfig('ba

i read book java memory modelling, says : hashmap use weak reference keys , values(since objects), hashmap can avoid out of memory issue when hasnmap stores more , more key value pairs. but problem : if keys , values being gc during rumtime, how can key value pair using get method in hashmap? for example, string key=new string("gc"); string value=new string("gc"); hashmap.put(key,value); and after execution of code, has chance java gc key , value, happen during: hashmap.get(key) since key no longer exist in hashmap ? it's weakhashmap, removes entries keys no longer referenced outside map itself. , happens after gc cleared key, here: map m = new weakhashmap(); m.put(new object(), 1); // key referenced map system.out.println(m.size()); // prints 1 system.gc(); thread.sleep(1); // give gc time system.out.println(m.size()); // prints 0

i have question, paypal ipn txn_id unique each transaction? mean is, possible have 2 separate transactions, same txn_id? because i'm using txn_id has order id in database, , wanted know if there risk of having duplicated txn id's on 2 different purchases. thanks. within each environment -- sandbox , live -- transaction ids unique. there crossover same transaction id exists on both sandbox , live, represent different transactions. additionally, in 99.999999% of cases, if have live transaction id, corresponding sandbox transaction id belong else (and vice versa). ergo, careful don't store both live , sandbox transaction ids in same table , should fine.

thinking of dilema, , looking ideas or better, proven process following: imaging have device has no interface small footprint server running on it. device meant collect , send data cloud. to configure it, 1 need access server. to access said server, device first need connected network. with wired network interface, it's possible connect , access server configure wifi access , such, if device wifi only? i'm guessing there ways auto-connect unsecured wifi network, connecting secured network poses problem. any thoughts on proper way this? i'm thinking of approach tethering laptop or cellphone first connect, not sure how can implemented (on laptop or device) thanks thoughts. my solution has been set device in wifi ad-hoc mode (i.e. device can discovered device in ad-hoc mode) , run small web server scans wifi routers around select from, , ask user device input credentials, re-configure wifi credentials.

i have function, getmonitors inside service. getmonitors returns list of monitor objects. if monitor object empty, grabs monitors via http , stores objects in monitor object array , returns it. function coded promise. know http returns promise, function may or may not use http - i've overlaid own promise (see below code) controllers can call getmonitors(0) or getmonitors(1). 0 means if loaded in monitors array due previous call, don't load again. (1) means force reload array http the service , associated getmonitors coded following way: angular.module('zmapp.controllers').service('zmdatamodel', ['$http', '$q', function($http, $q) { // var deferred=''; var monitorsloaded = 0; var monitors = []; getmonitors: function(forcereload) { console.log("** inside zmdata getmonitors forcereload=" + forcereload); var d = $q.defer(); if ((monitorsloaded == 0) || (f

i have inherited legacy sql code following snippet (i've anonymized simplicity sake). create external table dim_abc (user_id int) create table dim_foo select user_id, ... my_table join (select * dim_abc) b on (a.user_id = b.user_id) instead of... from my_table join dim_abc b on (a.user_id = b.user_id) any idea why previous developer have done select within join? ** code hive. the version without subselect better variety of reasons. databases (you don't mention database) lose ability use indexes on dim_abc because of subquery. that not question, though. best guess code started out more complicated. dim_abc might have required logic @ 1 point in time. code simplified, end result useless subquery in from clause. guess, offers 1 plausible scenario.

i looking method encrypt media can read while person has "active" account eg. media cannot stolen... seem not make sense if application displaying media can decrypt media , display actual photo. is encryption slow? you can achieve such functionality using two-way encryption/decryption, based on password phrase (in binary format) , two-way encryption algorythm, xor example. xor encryption/decryption has linear complexity, it's extremely fast , hard crack encrypted data if don't know encryption algorythm has been used in first place. the actual xor password phrase can associated user's account. long account active, password phrase can accessed , therefore encrypted media can decrypted. if user offline (logged out), password phrase inaccessible , therefore encrypted media stays encrypted. this can implemented service - user downloads music can played while user logged in (i.e. has means access password phrase decrypt music , play it). if key r

i have 2 enterprise servers need communicate in secure way, , comparing using ssl (with client/server certs validate both sides) vs two-legged authentication using oauth 2.0 (optionally mac tokens or jwt tokens). historically oauth seems have been created totally different purpose (the 3-legged case user allowing service access data somewhere), , although two-legged integrated oauth 2.0 spec, have seen two-legged oauth 2.0 doesn't seem offer additional protection on ssl. the point can think of oauth potentially easier configure ssl, , easy make mistakes things accepting bad ssl certs can compromise security. not sure if reason enough go oauth. note mention these separate options, think using oauth entail using on top of https/ssl, both used. is there real advantage of using oauth 2.0 two-legged scheme server-to-server communication (no user involved)? note: did find a similar post here , quite old don't feel gave satisfactory answer on matter. i'll re
