my application has thread pool creates 3 simultaneous threads. invoke runnables, added thread pool. my problem happens when application goes background while. eventually, threads stop executing runnables in pool , pool continues grow. if bring application foreground, threads not start running again. my theory when application goes background threads being killed. i'm not sure , i'm not sure of way of determining whether threads killed can start them again. do have suggestions can determine whether or not thread has been killed? you can't use thread pool execute code in background because android activity lifecycle won't consider app active, , kill process (including threads) after lose ui focus. want android service has different lifecycle. things use local service handler , handlerthread can post runnables into. you'll want similar. note: every time feel there must easier way, might worth searching if has simplified pattern.

what best approach if want of rows in database table have image. should add column type blob, or should keep reference image , add image in documents folder? there both advantages , disadvantages storing image data (or other large chunks of binary data) in database. on upside: all of app's data contained within single file depending on database, may have option of transactional/atomic updates app's data, avoiding problems app data gets unexpected states during error conditions the disadvantages are: the db larger there may optimizations associated working image data filesystem lost (e.g. - memory mapping) the memory footprint working images may increased depending on db granularity during writes, there may increased contention/blocking decreases speed @ db updated if 1 wanted make lot of separate, transactional/atomic changes quickly

using net-snmp api , using mib2c generate skeleton code, possible support delayed initialization of tables? mean is, table not initialized until of it's members queried directly. reason member data obtained server, , i'd able start snmpd daemon without requiring other server online/ready requests. thought of maybe initializing table dummy data gets updated real values when member queried, i'm not sure if best way. the table has 1 row of entries, using mib2c.iterate.conf generate table iterators , dealing of seems unnecessary. thought of maybe implementing sequence defined in mib , not actual table, that's not how it's done in examples i've seen. looked @ /mibgroup/examples/delayed_instance.c, that's not quite i'm looking for. using mib2c mib2c.create-dataset.conf config file closest got getting work easily, config file assumes data static , not external (both of not true in case), won't work. if it's not done, i'll implement sequence ...

possible duplicate: php session security i using sessions throughout application. want make them more secure. using code $username = $_session['username']; , like. how make sessions more secure? the first thing you'll want watch out session hijacking . quote wikipedia: in computer science, session hijacking refers exploitation of valid computer session—sometimes called session key—to gain unauthorized access information or services in computer system. in particular, used refer theft of magic cookie used authenticate user remote server. has particular relevance web developers, http cookies used maintain session on many web sites can stolen attacker using intermediary computer or access saved cookies on victim's computer (see http cookie theft ). the basic idea is, if visitor website (alice) has session cookie , session id (let's assume it's 12345 ), if malicious user (mallory) able learn alice's session id via either javas...

i have been unable figure out problem - doesn't make sense. the server php 5.2.6 running on windows nt pdp-iis 5.2 build 3790. first have confirmed sessions working via test script: <?php session_start(); if (!isset($_session['counter'])) $_session['counter']=0; echo "counter ".$_session['counter']++.".<br><a href=".$_server['php_self'].">reload</a>"; ?> the counter increments - works. my site using custom built mvc framework (i wrote it), , put last code of app function testing purposes: echo session_id(); echo '<pre>'; var_dump($_session); echo '</pre>'; session_write_close(); exit(); the first few lines of file are: <?php error_reporting(e_all); ini_set('display_errors', '1'); session_start(); the session dumps , looks expected. go server , open session file - , result appears depend on browser i'm using. chrome , saf...

i wonder whether should start development of new ios project in xcode 4 or 3.2 - on 1 hand, know 3.2 (a little), there lots of info out there, , it's stable , proven. on other hand, xcode 4 brings improvements well. newer previews of xcode 4 ready prime time, or still buggy? i'm interested in issues (and recommendations of) externally hosted repositories, not happy how xcode 3.2 played subversion repository in last project. which 1 choose, , (preferably free , externally hosted) repository match? today (3rd feb 2011) apple released gm-seed of xcode4. it's ready usage , can compile apps , release app-store. if new xcode, suggest using xcode4. why? the new compiler has lot of optimizations done. compiler (as far can see results) generates faster code. it's big fun! the new userinterface more reliable. makes development lot faster! 2a. interface builder integrated. can "drag , drop" userinterface item using "ctrl"-key code , xco...

i have 2 models: user , lesson. want lessons assigned users admins. what best way ensure this? attempting create custom validator so: class belongstoadminvalidator < activemodel::eachvalidator def validate_each(object, attribute, value) unless value.admin? object.errors[attribute] << (options[:message] || "must belong admin") end end end but leads rspec saying: undefined method `admin?' nil:nilclass which makes sense. is custom validator best way this? or should checking if to-be-assigned user admin in controller? i think easiest way of doing is: # lesson model validate :allow_only_admins private def allow_only_admins errors.add(:user, "must admin user!") if (user.blank? || !user.admin?) end i assumed have association named user , user object responds admin? method.

this seems simple question can't seem find simple answer. django seems give nifty simple way of limiting access places using permission required or login required decorators can't see django docs how 1 pass error message (maybe using messages framework). if have roll own decorator this, point of django decorators? not show error messages? i'll assume avoided reading this http://docs.djangoproject.com/en/1.2/topics/auth/#the-login-required-decorator login_required() following: if user isn't logged in, redirect settings.login_url , passing current absolute path in query string. example: /accounts/login/?next=/polls/3/ . if user logged in, execute view normally. view code free assume user logged in. there no "error messages". error messages rude. , largely useless. they're sign of bad design. generally, don't need million tiny little explanations. indeed, default login page works fine 80% of use case...
