i have java servlet that's getting overloaded client requests during peak hours. clients span concurrent requests. number of requests per second great. should implement application logic restrict number of request client can send per second? need done on application level? the 2 common ways of handling turn away requests when server busy, or handle each request slower. turning away requests easy; run fixed number of instances. os may or may not queue few connection requests, in general users fail connect. more graceful way of doing have service return error code indicating client should try again later. handling requests slower bit more work, because requires separating servlet handling requests class doing work in different thread. can have larger number of servlets worker bees. when request comes in accepts it, waits worker bee, grabs , uses it, frees it, returns results. the 2 can communicate through 1 of classes in java.util.concurrent , linkedblocki

what know is, using rmelem remove folder first, , cause of child elements moved lost+found . then, go lost+found , , repeatedly execute rmelem * until of elements removed. is there better way? the technote lost+found quite clear: if rmelem directory, content indeed moved lost+found , has lost+found . technote adds: note: if directory element deleted lost+found rmelem , contents moved lost+found in same manner described in first section above. that why try rmelem files first, directories , in order avoid trip (or several trips) in lost+found . except rmelem anything , same technote warns: use rmelem when deleting elements or symbolic links lost+found directory. while content of lost+found typically consists of unwanted elements , symbolic links, in circumstances can contain elements cataloged elsewhere in vob (that is, not orphaned) associated symbolic or hard links. reason, not run rmelem recursively in lost+found without first verif

what purpose of .edmx files? reading csdl, ssdl, , msl specifications, looks me .edmx files used @ design time. meant distribute other edmx? seems need distribute .ssdl and/or .csdl files instead. edmx visual studio's "container" things entity data model. it contains information in csdl, ssdl, msl, plus information visual layout of tables in visual studio designer surface. the edmx file converted csdl, ssdl, msl (typically embedded resources in assembly) during build process. don't have distribute or copy edmx files anywhere app run. update: if more interested in code-based approach, should check out code-first ctp entity framework gets without .edmx, .csdl/ssdl/msl files @ all.

further this question, i'm looking device allow me connect 2 usb hosts, while still being programmable. can following: masquerade arbitrary usb device take input pc , nothing pass on other host. i've been looking microcontroller (preferably pre-assembled) allow me this, have far come blank. know of controller (preferably cheap) allow me this? take input pc , nothing pass on other host. this non-sensical usb perspective. usb host-based protocol: device never send data unless host requests first. keep in mind here, 'host' , 'device' have specific meanings here within protocol itself; can think of 'host' master , 'device' slave. these roles baked usb controller. there no way convince standard usb controller in given pc or peripheral swap roles. there add-in cards pcs usb device controllers (making pc act device), 'cheap' not word use describe them. what trying create usb device device bridge. so, alright, need hav

http://pastebin.com/xrzbvwse so, have textarea input has spaces @ beginning. press submit button, goes through php , echos same stuff again input correction. so, if have had 3 spaces have 2. , if press button again, im getting 1. on each button press, deletes me 1 space. dont trim anywhere. why that? easy solution att "\n" xmldata i'd know problem is. most problem not code. appears how textarea input fields work, i.e. ignore first empty line (have at, e.g. here , here or here ) 1 possible workaround add &nbsp; first empty line, rather have empty, or add \n suggested.

i´m paginating will_paginate plugin. i have popup adds @products when user clicks button add via ajax request. note: @products paginated in ajax request update product-list : ids = params[:accessories][:id].join(" , id <> ") @products = product.find_by_sql("select * products id <> #{ids}") however if use: @products = product.find_by_sql("select * products id <> #{ids}").paginate it returns identical array. so how paginate array again? why using find_by_sql method? may can write this: ids = params[:accessories][:id].join(",") @products = product.paginate(:page => params[:page], :conditions => ["not (id in (?))", ids]) also conditions can move product model , replace scope(rails 3) or named_scope(rails 2).

basically , wondering if there handy class or method filter string unwanted characters. output of method should 'cleaned' string. ie: string dirtystring = "this contains spaces not allowed" string result = cleaner.getcleanedstring(dirtystring); expecting result be: "thiscontainsspaceswhicharenotallowed" a better example: string reallydirty = " this*is#a*&very_dirty&string" string result = cleaner.getcleanedstring(dirtystring); i expect result be: "thisisaverydirtystring" because, let cleaner know ' ', '*', '#', '&' , '_' dirty characters. can solve using white/black list array of chars. don't want re-invent wheel. i wondering if there such thing can 'clean' strings using regex. instead of writing myself. addition: if think cleaning string done differently/better i'm ears of course another addition: - not spaces, kind of character. edit

when profiling application (using dottrace), noticed strange thing. used "wall time" measurement, should in theory mean threads run same amount of time. but wasn't true: threads (actually interested in) displayed total time 2 times less others. example, profiling ran 230 seconds, most threads report 230 seconds spent in thread, 5 threads show 100-110 seconds. these not threadpool threads, , created , started before profiling started. what going on here? update i'll add more info may or may not relevant. application in question (it game server) has 20-30 running threads. threads follow simple pattern: check incoming queue work, , work if there some. code thread func looks this: while(true){ if(trydequeuework()){ // if queue not empty dowork(); // whatever on top }else{ m_waithandle.waitone(maxtimeout); // m_waithandle gets signaled when work added queue } } the threads display weird times this, except serve multiple q

when there non-string(i.e. : varchar,date) column(col1) in oracle db, if do: select * table order col1 asc it orders properly. (ie. date, orders oldest latest, numeric, lowest highest) if do, select * table order upper(col1) asc ordering not correct. what cause behavior? upper takes string , returns string. if col1 other string, have implicitly cast string before function executed. since output of upper function string, however, sort have use string sorting semantics, not sort semantics of col1 . if col1 numeric, example upper(9) returns string '9' upper(10) returns string '10' the string '9' comes alphabetically after string '10' is, presumably, problem you're seeing. but if col1 not string, why bother converting upper case in order sort?

when navigating using button on phone how can refresh viewmodel? i'm using button on phone believe same calling navigationservice.goback(), navigates previous page on stack constructor not called in view or viewmodel. you can hook in base page class onnavigatingto event , call method on viewmodel. don't have vs me pseudo-code be: in mybasepage : page public void onnavigatingto(object sender, eventargs e) { var vm = this.datacontext baseviewmodel; if(vm != null) { vm.initialize(); } } you can same before leaving page: public void onnavigatingfrom(object sender, eventargs e) { var vm = this.datacontext baseviewmodel; if(vm != null) { vm.save(); } }

i have following environment: seam 2.2.0 ga default richfaces version. how define default column (field) datatable sort records field? tried setting default value "sort" parameter in .page.xml file didn't help. in addition, entitylist.java returns null when system.out.println(this.getordercolumn()); mean sorting happens @ client side? if so, why entitylist() called each time re-sort list? thank you i think entitylist class must extend entityquery, can add these 2 lines in constructor of entitylist: setordercolumn("yourentity.property"); setorderdirection("asc"); or add 1 line: setorder("yourentity.property asc"); i know hard-coded, bad works. if has better way, please share us. thanks.

i have tried multiply large integers (also tried double) in xcode. used nslog track errors in calculation (simple calculations) , noticed when multiply variables large values such (i looked them nslog): 31536000 * 91 = 2869776000 1610612736, wrong. do wrong? /d what type of data use numbers? if nsinteger, or that, it's close standard int, has limitation. for example, on standard 64 bits architecture can declare long long int permits have 64 bits integer. if multiplication requires more place, left bits may truncated, changes result. you use long double, permits handle 80 bits numbers extended double precision, still loose precision on big numbers.

i downloaded mvc2 futures , referenced current mvc2 project. however, if want call htmlhelper mvc2 futures need <%@ import namespace="microsoft.web.mvc" %> so decided add on web.config: <pages> <namespaces> <add namespace="system.web.mvc" /> <add namespace="system.web.mvc.ajax" /> <add namespace="system.web.mvc.html" /> <add namespace="system.web.routing" /> <add namespace="microsoft.web.mvc" /> <add namespace="xpedite.mvc.html" /> </namespaces> </pages> but, caused me errors. assemblies co-exist? if yes, how? i'm pretty sure need mvc3 futures pack: http://aspnet.codeplex.com/releases/view/54306 the mvc2 future made work against mvc1. had same issue , upgrading next futures release solved me.

assuming have decorator , wrapped function this: def squared(method): def wrapper(x, y): return method(x*x, y*y) return wrapper @squared def sum(x, y): return x+y i have other code call undecorated version of sum function. there import trick can me unwrapped method? if code says from some.module.path import sum then, wrapped version of sum method, not want in case. (yes, know break out helper method, breaks of cleanliness of pattern i'm going here.) i'm okay adding "magic" decorator provide alternate symbol name (like orig_sum ) import, don't know how that. def unwrap(fn): return fn.__wrapped__ def squared(method): def wrapper(x, y): return method(x*x, y*y) wrapper.__wrapped__ = method return wrapper @squared def sum(x, y): return x+y sum(2,3) -> 13 unwrap(sum)(2,3) -> 5

i'm working on java application @ moment , working optimize memory usage. i'm following guidelines proper garbage collection far aware. however, seems heap seems sit @ maximum size, though not needed. my program runs resource intensive task once hour, when computer not in use person. task uses decent chunk of memory, frees after task completes. netbeans profiler reveals memory usage looks this: i'd give of heap space os when not in use. there no reason me hog while program won't doing @ least hour. is possible? thanks. you perhaps play around -xx:maxheapfreeratio - maximum percentage (default 70) of heap free before gc shrinks it. perhaps setting bit lower (40 or 50?) , using system.gc() might go lengths desired behaviour? there's no way force happen however, can try , encourage jvm can't yank memory away , when want to. , while above may shrink heap, memory won't handed straight os (though in recent implementations of jvm does.)

is possible record window's output sounds programmatically in c#? bit recording "what hear" or "stereo output" feature (without having select them)? this called loopback recording , , is possible in windows. if have soundcard supports loopback (i checked on low-end toshiba laptop, , doesn't) can record straight loopback device using waveinopen etc. api, easy use in c#. note: recording audio in way entails reduction in quality, since audio signal converted analog output , re-digitized support loopback interface. if don't have soundcard, wasapi let this. suppose wasapi can used c#, looks painful.

i read mutexes , semaphores maintain list of waiting processes , wake them when current thread completes critical section. how mutexes , semaphores that? doesn't interfere process scheduler decisions? the waiting , waking typically done in cooperation scheduler. mutex implementation forces specific 1 of waiting threads wake typically considered poor implementation. instead, mutex or semaphore notify scheduler thread waiting, , take off "ready run" list. then, when mutex unlocked or semaphore signalled, implementation either ask scheduler wake 1 of waiting threads @ scheduler's discretion, or notify scheduler waiting threads ready run, , have logic on waiting threads first 1 woken scheduler go sleep again. the former preferred implementation choice, not available. second dubbed "thundering herd" approach: if there 1000 threads waiting 1000 woken (a big thundering herd of threads), 999 go sleep. wasteful of cpu resources, , implementatio
