regarding ipad events, how determine if/when ipad changing awake state standby state? what put mobile-safari web app in locked state whenever ipad becomes inactive/standby , ask pin when becomes awake again. i agree there ought signal can hook on to know when application goes sleep , when wakes up, should able figure out when safari wakes indirectly. when webview goes background, safari puts in sleep. pauses video, defers network request, stops updating ui , pauses setinterval/settimeout operations. js never aware (as far can tell) how these things happened, can tell has happened. simplest way use build regularly invoked method , check see if it's been unexpectedly long time since last update. if expect update every 10 seconds , it's been 5 minutes, can sure device has woken up. here's quick example thought up: var inttime = new date().gettime(); var gettime = function() { var intnow = new date().gettime(); if (intnow - inttime ...

i using drupal , website uses approx 30mb per page load nodes , user profiles. website has round 150 contributed modules in addition few core optional modules. of them small , installed improve user experience. my php memory limit 128mb. is 30mb per page acceptable?? , how many page loads can handled in 128mb?? any idea? honestly, @ 30mb app sipping on memory. php memory limits set pretty low. as far how many "page loads can handled 128mb" of memory, well, that's not valid. when request comes in, apache (or whatever server you're using) hands request mod_php or fcgi , php code interpreted, compiled, run, , quit. "application" doesn't act daemon waiting requests come in, memory consumes used duration of request , gets released use other requests/processes. that 128mb limit per request . means long have enough memory (and apache child processes, etc) can handle additional requests. if want see how application performs under load, che...

i want achieve "virtual space" functionality, similar 1 in visual studio, in avalonedit. i.e. caret positioned beyond end of text line, , if press key, there spaces automatically added match. i used feature, neither googling nor studying avalonedit's code gave me clues on how enable it, if supported @ all. if not, suggestions how extend caret handling mechanisms nice. thanks! edit: virtual space support has been added avalonedit in version 4.2.0.8283. set texteditor.options.enablevirtualspace = true; . below original answer. it's not supported. if want try adding it, make sure read "coordinate systems" documentation (in file on codeproject). you'll want extend "visual column" positions after line end valid. , you'll have adjust position<->column calculations (visualline.getvisualcolumn , friends). use textview.widespacewidth figure out columns past end of line. the above should allow use mouse place ca...

recently in answer suggested me this: public interface operation<r extends operationresult, p extends operationparam> { public r execute(p param); } is better this: public interface operation { public operationresult execute(operationparam param); } i can't see benefit in using first code block on second 1 ... given both operationresult , operationparam interfaces implementer needs return derived class anyway , seems quite obvious me. so see reason use first code block on second 1 ? this way can declare operation implementations return more specific result, e.g. class sumoperation implements operation<sumresult, sumparam> though whether of value application depends entirely on situation. update: of course return more specific result without having generic interface, way can restrict input parameters well.

is there exist case insensitive find() method std::string? you upper-case both strings , use regular find.

i've asp.net application served on https. noticed in logs none of resources files (css/images/js/xsl) being served 304 header, should since i'm sending necessary headers correctly. client's browser settings are: check newer versions of stored pages: 'automatically' disk space use: 65 days keep page in history: 7 do not save encrypted pages disk:checked on i assume last setting preventing user's browser use cached files. correct? i've seen fresh copies of same file being requested in same session well. question "do not save encrypted pages disk" feature prevents https caching within same browser session well? if yes, there way deal other serving static pages through sub domain w/o ssl? thanks help! ps: noticed interesting thing. have emptu.html file (that more static placeholder) served on same ssl , file status code 304. if caching not allowed on ssl due client settings how come file being used browser cache same user?

i have shared hosting account , using filezilla connect server. under public_html/items/ folder, there many subfolders , folder names encoded using php rawurlencode function, these: apple banana orange %e6%bc%a2%e5%a0%a1%e9%a3%bd %e8%96%af%e6%a2%9d the problem 404 error when access files under folders names contain non-ascii characters (e.g. chinese characters). this means can access url one: http://my-domain.com/items/apple/index.html but not: http://my-domain.com/items/%e6%bc%a2%e5%a0%a1%e9%a3%bd/index.html what kind of problem possibly be? many all. if folders contain physically urlencoded names, you'll need ensure these names urlencoded in urls. in fact, anytime create url 'uncontrolled', potentially url-unsafe elements, must urlencode elements. thus if have directory named %e8%96%af%e6%a2%9d you refer in url %25e8%2596%25af%25e6%25a2%259d pretty, isn't it? another way of looking @ when use existing urlencoded url, server tries r...

i contemplating jump git bandwagon. environment made 1-4 windows client machines , single freenas server. what need make git work in type of configuration? is there git software need install on server? (in cvs, example, don't need install software, if repository accessed windows (smb) share). what install on client machine (windows) if have cygwin installed? there pre-compiled git.exe (just cvs.exe) takes less space proposed 130mb msysgit ? do have go through compiling git binaries in order have git on windows client? i totally clueless move cvs paradigm git paradigm entails. please bare me. thanks. git not same svn or cvs, since "fully distributed", there not clients , server, nodes. in case you'll want "client machines" pointing remote repo on nas, can push changes. can point repo using many methods including file, outlined here: http://www.kernel.org/pub/software/scm/git/docs/git-push.html#urls in git clients nodes too, example...

the problem draw arc 2 pints on bitmap radius , clockwise direction. from one-sentence question, i'm gonna assume you're ok drawing bezier curves. if not, there plenty of information them out there. anyway, cannot create perfect circular arc bezier curves (or splines). can approximating circle level eye won't able see difference. done 8 quadratic bezier curve segments, each covering 1/8th of circle. i.e. how adobe flash creates circles. if you're after plain parametrization using sin , cos, it's way easier: for (float t = 0; t < 2 * math.pi; t+=0.05) { float x = radius * sin(t); float y = radius * cos(t); }

in c++, how handle hash collision in hash map? , how time spend search element if collision occurred? and, hash function? there dozens of different ways handle collisions in hash maps depending on system you're using. here few: if use closed addressing , have each item hash linked list of values, of have same hash code, , traverse list looking element in question. if use linear probing , following hash collision start looking @ adjacent buckets until found element looking or empty spot. if use quadratic probing , following hash collision @ elements 1, 3, 6, 10, 15, ..., n(n+1)/2, ... away collision point in search of empty spot or element in question. if use cuckoo hashing , maintain 2 hash tables, displace element collided other table, repeating process until collisions resolved or had rehash. if use dynamic perfect hashing , build perfect hash table elements sharing hash code. the particular implementation pick you. go whatever simplest. find chained h...

i had problem in simulator - when want edit table in core data or create new table program using database fails every time start it. google problem , found solution - every time want change in tables have manually delete database. works fine nowadays license testing on real device, not know how works on real device. work company , maybe database expanding new tables, , not know how prevent in real device. admit strange problem, can me? if change core data model during testing, can delete app simulator/device. in case xcode install new database on simulator/device when re-install app , app won't crash. if app has been released in itunes , want change database, have implement data migration in app. hope understood question right. please ask if have more questions.

i'm in situation need pass texts prompt generate api (seems api it's pretty weird behavior, first time ran this), below: kvm_cli = libvirt.open("qemu+ssh://han@10.0.10.8/system") then prompt shows asking ssh password ( password 10.0.10.8 is: ), have manually type there in order move on , yield kvm_cli object needed. i tried use pexpect module deal it's os command line instead of api. it's possible work around using ssh certification files it's not favorable authentication approach in our scenario. since our wrapper 'open' method not interactive, cannot ask user input password, guys have thought how address it? i not libvirt user, believe problem not in library, in connection method. seem connecting via ssh, need authenticate yourself. i've been reading libvirt page on archwiki , , think try: setting simple (tcp/ip socket) connection method, or setting key-based, password-less ssh login virtual host.
