i have quite large website, in there forum powered phpbb. have apc enabled 1gb of ram. phpbb generates lot of php files of cache (60 000-70 000 in case), , rapidly fill apc memory . thinking disable apc caching of such files through apc.filter option. in opinion, make sense? i haven't run phpbb in long time, answer conditional: if there's actual php code in cache files, there's worth had in caching in apc. might go step further , they're incredibly valuable cache, since phpbb feels these files used enough have been worth caching. if contain static html or other content that's not php, filter them out or convince phpbb give them alternate extension. how fast running through data in apc? if you're cycling through cache misses incredibly quickly, you've got problem. if number of misses stays constant , low on time wouldn't worry it. if you're storing lots of user data in apc might way shave down. apc.php great way more details on a...

i'm trying learn singleton classes , how can used in application keep thread safe. let's suppose have singleton class called indexupdater reference obtained follows: public static synchronized indexupdater getindexupdater() { if (ref == null) // it's ok, can call constructor ref = new indexupdater(); return ref; } private static indexupdater ref; let's suppose there other methods in class actual work (update indicies, etc.). i'm trying understand how accessing , using singleton work 2 threads. let's suppose in time 1, thread 1 gets reference class, through call indexupdater iu = indexupdater.getindexupdater(); then, in time 2, using reference iu, method within class called iu.updateindex thread 1. happen in time 2, second thread tries reference class. , access methods within singleton or prevented long first thread has active reference class. i'm assuming latter (or else how work?) i'd make sure bef...

i've got form. in form, user can fill out few fields, click "add". data gets turned html element, , form gets (partially) cleared can type more data. i'm trying figure out how store data when clicks "add" can submitted later. should serialize (json? or there more compact representation--doesn't need human readable) , store in hidden field? if so, happens when adds 2nd object? deserialize old data, , reserialize 2 objects together? seems inefficient. do somehow clone form, hide it, , update name attributes don't conflict, , kill myself trying parse these stupid things array later? what's best approach? create hidden field incremental numerical suffix somewhere in name. var fields = $('input[type=hidden][name^=foo_]', form).length; $('<input type="hidden" name="foo_' + (fields + 1) + '">').val(val).appendto(form); submit usual way, jquery.serialize() , on. finally intercep...

this question has answer here: test if variable matches of several strings w/o long if-elsif chain, or case-when 3 answers example if fileext "doc" if fileext equal either ("doc", "xls", "ppt") any ideas? use regular expression: do_x if file_ext =~ /\a(doc|xls|ppt)\z/ or, if have large enough list of things writing regex feels impractical, like file_extensions = %w(xls csv doc txt odf jpg png blah blah blah blah blah) do_x if file_extensions.include?(file_ext) of course there option of testing each value individually: do_x if file_ext == "doc" || file_ext == "xls" || ... || file_ext == "zzz"

i writing "triangle solver" app android, , wondering if possible implement exact values trig ratios , radian measures. example, 90 degrees output "pi / 2" instead of 1.57079632679... i know in order exact value radian measure, divide pi , convert fraction. don't know how convert decimal fraction. like this: int decimal = anglemeasure / math.pi; somemethodtoturnitintoafraction(decimal); i don't know begin trig ratios. you need take number , divide each of "special" numbers: pi,e, sqrt(2), sqrt(3), sqrt(5). after each division, determine if resulting number close exact fraction. last part, use continued fraction algorithm find approximations number. there criteria can use in continued fraction expansion determine if approximation exact. if nice fraction small numbers exact that's answer - fraction times special number divided @ beginning. oh , consider "1" divisor simple fractions come out too. been there, done t...

have been trying figure out decent way of matching string patterns. try best provide information can regarding trying do. the simplest thougt there specified patterns , want know of these patterns match or partially given request. specified patterns hardly change. amount of requests 10k per day results have pe provided asap , runtime performance highest priority. i have been thinking of using assembly compiled regular expression in c# this, not sure if headed in right direction. scenario: data file: let's assume data provided xml request in known schema format. has anywehere between 5-20 rows of data. each row has 10-30 columns. each of columns can have data in pre-defined pattern. example: a1- "3 digits" followed "." follwed "2 digits" - [0-9]{3}.[0-9]{2} a2- "1 character" follwoed "digits" - [a-z][0-9]{4} the sample like: <data> <r1> <a1>123.45</a1> <a2...

ok, have lot of sales data each of our clients. have been able find query total volume of sales each sales rep using simple query: select `merchantaddresses`.`rep number` `rep number`, sum(`residuals_2010_12`.`qual cr vol` + `residuals_2010_12`.`qual ch vol`) `vol_2010_12`, `reps`.`first` `first`, `reps`.`last` `last` `merchantaddresses`, `residuals_2010_12`, `reps` `residuals_2010_12`.`mid` = `merchantaddresses`.`mid` , `reps`.`id` = `merchantaddresses`.`rep number` group `merchantaddresses`.`rep number` order sum(`residuals_2010_12`.`qual cr vol` + `residuals_2010_12`.`qual ch vol`) desc this code works totally fine, returning table grouping total sales sales rep single month. @ moment, have been running 3 separate queries sales data 3 months. want combine these 3 queries one. so, did following: select `merchantaddresses`.`rep number` `rep number`, sum(`residuals_2010_12`.`qual cr vol` + `residuals_2010_12`.`qua...

i have generic linked list implementation node struct containing void* data , list struct holds reference head. here problem node in linked list may hold reference linked list via void*. causes memory leaks when free bigger list containing smaller lists. wondering there way check if void* pointing list follow , free or data. if add key beginning of struct magic number can check dereferencing void* , figure out list? edit: callers don't insert smaller lists inserted functions not want callers deal relasing multiple lists 1 hold pointer to. this question depends on responsibility clean entries in list. if struct responsible cleaning memory referenced void * fields, have bigger problem @ hand here, namely given void * referencing arbitrary block of memory can never know right way deallocate is. example, if have implementation of dynamic array along lines of c++ std::vector , void * might point @ struct contains pointer, , list need know has descend struct recursi...
