i feel bit stupid asking, doesn't appear in documentation rq . have 'failed' queue thousands of items in , want clear using django admin interface. admin interface lists them , allows me delete , re-queue them individually can't believe have dive django shell in bulk. what have missed? the queue class has empty() method can accessed like: import django_rq q = django_rq.get_failed_queue() q.empty() however, in tests, cleared failed list key in redis, not job keys itself. thousands of jobs still occupy redis memory. prevent happening, must remove jobs individually: import django_rq q = django_rq.get_failed_queue() while true: job = q.dequeue() if not job: break job.delete() # delete key redis as having button in admin interface, you'd have change django-rq/templates/django-rq/jobs.html template, extends admin/base_site.html , , doesn't seem give room customizing.

sitecore has nice event queueing system persisted database. can define custom events . i need able raise event has delay before it's processed. possible? i use other queueing system ( apachemq ?), nice use built in sitecore 1 if possible. as far know not possible delay event directly. there way custom code want executed delay. you create custom event. in custom event handler use sitecore jobmanager execute specific method want start delay. using sitecore jobmanager able delay execution of method passing additional parameter "initialdelay". var options = new joboptions("jobname", "category", "sitename", "object instance contains method execute", "methodname") { initialdelay = timespan.fromminutes(5.0) }; jobmanager.start(options); you can use execute method on cd server delay, after triggering cms server using remote events. see this link more info sitecore jobs.

so, code looks right now: and when click on products ideally this: so, right code allowing me 1 product, option of adding unlimited amount of products. here's code: class purchaseorder(models.model): product = models.foreignkey('product') vendor = models.foreignkey('vendorprofile') dollar_amount = models.floatfield(verbose_name='price') class product(models.model): products = models.charfield(max_length=256) def __unicode__(self): return self.products how can this? or, rather, possible? use manytomanyfield instead of foreignkey.

this question has answer here: difference between var , in javascript functions? 2 answers i have following javascript code project @ school. (this code provided me.) can explain difference between var setdatarequest , this.setdatarequest understand happening in functions, not why functions created in fashion. similar overloading? tele.forms.controller = new function () { var _requestdata; this.setrequestdata = function (requestdata) { _requestdata = requestdata; }; var setrequestdata = function () { var fields = $('.formsmaintable'); var reqdata = ['request_record_id', 'date_submitted', 'requester_id']; .... .... }; .... .... }; this.setrequestdata available @ tele.forms.controller.setrequestdata , while var setrequestdata available internals of function. think of this.set

this simple question has been bothering me while now. i attempting rewrite code parallel, , in process need split sum done on multiple nodes , add small sums together. piece working this: def pia(n, i): k = 0 lsum = 0 while k < n: p = (n-k) ld = (8.0*k+i) ln = pow(16.0, p, ld) lsum += (ln/ld) k += 1 return lsum where n limit , i integer. have hints on how split , same result in end? edit: asking, i'm not using pow() custom version efficiently floating point: def ssp(b, n, m): ssp = 1 while n>0: if n % 2 == 1: ssp = (b*ssp) % m b = (b**2) % m n = n // 2 return ssp since variable that's used 1 pass next k , , k increments 1 each time, it's easy split calculation. if pass k pia , you'll have both definable starting , ending points, , can split many pieces want

it possible write perl documentation in utf-8. should write in pod: =encoding nnn but should write instead nnn ? different sources gives different answers. perlpod says that should =encoding utf8 this stackoverflow answer states should =encoding utf-8 and this answer tells me write =encoding utf-8 what correct answer? correct string written in pod? =encoding utf-8 according iana, charset names case-insensitive , utf-8 same. utf8 perl's lax variant of utf-8. however, safety, want strict pod processors.

i'm working in php application, , i'd able instantiate object, need instantiated of it's properties, not of them. eg. class user { public function __construct() { $this->user_id = 0; $this->name = ''; $this->profile = array(); //...many other members here } } every time instantiate object brings many collections of data, (for example, brings it's "profile" properties , on). , not wanted behavior because, let's need use name of user, why having in memory rest of properties? in other cases, need them right away. some ideas: i create class extends user, , in constructor method unset unwanted properties. however, i'm looking more reusable way, can same other objects in application. i take properties out of constructor method, force me change core of application (classes above user class), , alter many things in application. is there more reusable way using standard intermediary clas

i regularly find rolling things of time series (particularly means), , surprised find rollmean notably faster rollapply , , align = 'right' methods faster rollmeanr wrappers. how have achieved speed up? , why 1 lose of when using rollmeanr() wrapper? some background: had been using rollapplyr(x, n, function(x) mean(x)) , happened upon few examples using rollmean . documents suggest rollapplyr(x, n, mean) (note without function part of argument) uses rollmean didn't think there difference in performance, rbenchmark revealed notable differences. require(zoo) require(rbenchmark) x <- rnorm(1e4) r1 <- function() rollapplyr(x, 3, mean) # uses rollmean r2 <- function() rollapplyr(x, 3, function(x) mean(x)) r3 <- function() rollmean(x, 3, na.pad = true, align = 'right') r4 <- function() rollmeanr(x, 3, align = "right") bb <- benchmark(r1(), r2(), r3(), r4(), columns = c('test', 'elapsed', 'rela

i need send packet of data on udp connection in c++. first message need send built of 2 32 bit integers , 64 bit integer. best way combine multiple variable types 1 block of data ready sending on udp connection? it depends on requirements network. care endianness? if do, should use not serialisatioin, safe 1 in regards endianness. generally, each class/struct sendable through network should have special methods or overloaded operators stream them in , out. you'll have use macros/functions hton/ntoh streaming primitive types eg int, int64, float, double etc. upd: if network endpoint applications run on different platforms/compilers, may have different sizes of int, long, short etc. when serialising, you'll have convert integers predefined types sizes guaranteed same on supported platforms.

first of all, extremely new sql reporting services, guess causing issue off. basically, first page of reports spit out fine, when 2nd+ pages hit, width of table greater 8.5 (which interactivewidth set to) inches because clips off page, , creates whole other page looks blank, if closely see edge of table previous page on left side so: i suspect might have possible word wrapping issue on particular tablecell: because on 2nd+ pages, same tablecell displays as: which seems width coming making table wide page width. help. ssrs doesn't allow column width change dynamically, don't have worry that. settings need adjust page size , margins. if default margin on each side 1 inch, left 6.5 inches width work with. try reducing margin first, should fix it.

the page in question setup page software. want user paste license key textarea . have option validate (validation done on controller) , can 'apply' ( saved in reg key on server' however seem have hit maximum length can sent controller. key being passed string fails error longer 2142 characters . ( keys 2500 ish) so thought i'd clever , use slice split long license key 2 or 3 parts, seem hit shorter 'overall' length restriction. so here code slitting 2 strings , works fine if leave overall length @ 1800 if try adding 3rd or increase overall length on 2000 (roughly) error , break point @ controller never reached. controller function updatelicense(params configparams, newlicensekeya string, newlicensekeyb string) emptyresult dim lickey string = newlicensekeya + newlicensekeyb 'just testing return nothing end function and here view $(document).ready(function () { $("#checklicense").bind("click", function

the team using android studio develop android projects. researching unit tests, looks support junit test cases in eclipse. after exporting test project eclipse , importing android studio under mistaken impression go , forth. when added java class project in android studio, new java class not show in eclipse project. i import new class if wanted move different location first. so, there way eclipse project recognize file on disk should included in project?

i have field set type date in mysql table. day, month , year user , @ moment have values returned this: [start_datemonth] => 08 //$stardmonth [start_dateday] => 7 //$startday [start_dateyear] => 2013 //$startyear how can convert valid date can insert in database? this own code, reasons browser shows blank screen no source code inside: $format = 'y-m-d h:i:s'; $start = datetime::createfromformat($format, "$startyear-$startmonth-$startday $starthour:$startminutes:00"); echo $start; from manual although mysql tries interpret values in several formats, date parts must given in year-month-day order (for example, '98-09-04'), rather in month-day-year or day-month-year orders commonly used elsewhere (for example, '09-04-98', '04-09-98') .dates containing two-digit year values ambiguous because century unknown. mysql interprets two-digit year values using these rules:year values in range 70-99 are converted to1970-19

the windows v7.1 sdk has setenv.cmd script in binary folder correctly setup environment. problem script works cmd.exe , can't find equivalent powershell anywhere. so forced use cmd.exe or there way use powershell (apart manually rewriting setenv.cmd script - if work?). someone wrote ps1 script parses out sdk's setenv can avoid processes: http://www.tavaresstudios.com/blog/post/the-last-vsvars32ps1-ill-ever-need.aspx

this odd me. downloaded google play games app (distributed google, inc.) , shown on device required no special permissions (on device): this peculiar because using application there quite few things should require permissions. network access, accounts access, etc. also, other apps google, inc. i've checked still require permissions expected... another oddity looking @ app on play store via computer shows require permission, although access accounts , not other permissions 1 expect: my question, how possible application not require necessary permissions , how can discrepancy between viewing store on device , through web browser explained? how possible application not require necessary permissions it may not doing operations itself. may having third-party perform actions it. example, might use custom signature -level permission have play services framework app things on behalf. how can discrepancy between viewing store on device , through web browse

i'd soft keyboard identifier in android purpose of determining keyboard height. end goal want reposition view on screen vertically centered between top of keyboard , bottom of status bar. can status bar height following code: int statusbarheight = 0; int resourceid = resources.getidentifier("status_bar_height", "dimen", "android"); if(resourceid > 0) { statusbarheight = resources.getdimensionpixelsize(resourceid); } can height of soft keyboard in similar way? using xamarin because sharing backend between ios app , android app, code seems pretty similar android. creating views entirely in code prefer; question how can keyboard height in code in order position view in code? you can using viewtree observer . root view, you'll able calculate new size when keyboard appears. the question below may you, helped me: is there way in android height of virtual keyboard of device

i'm new docpad. idea of static page generation , had in mind time, great there's mature project out there! however, while rough picture of how docpad works, recommend best way of creating simple contact me page, email input text specific address? there still requirement server side code this. how see doing right now, having html form doing post nodejs server handle sending email. is correct docpad way of doing it, or i'm missing something? check out contactform plugin :)

i'm trying understand happens when make concurrent access pointers methods? i have map of pointers , spawn off few go routines. pass map each go routine , each go routine use 1 of values in map. nothing being written map being read from. the map small, 4 keys it's possible more 1 go routine using same value map. question is, happens when 2 go routines call method of same pointer? unpredictable results? edit example: i'm taking out map portion that's not question i'm after. i have foo pointer of type mystruct , structure has method dosomething takes arguments. in main function i'm creating 2 go routines , both of them make calls foo.dosomething passing different values. in example first go routine has larger calculation preform second 1 (just using sleep times here simulate calculations). again nothing in structure changing i'm making call structures method. have worry second go routine making call foo.dosomething when first go r

in java how create array of class definitions , create class array? list<class> blockarray = new array<class>(); blockarray.add(ltetrino.class); i stuck when comes this, how create class classname? public tetrino getblock(int x, int y) { // return new ltetrino(x, y); old code return new blockarray.get(blah); } i'm pretty sure i'm doing wrong here. in advance. see class.newinstance() . for example: list<class> blockarray = new arraylist<class>(); blockarray.add(ltetrino.class); // instantiate object of class added ltetrino block = blockarray.get(0).newinstance(); if class constructor takes parameters, can use getconstructor() method of class retrieve appropriate constructor, , invoke instead (it's linked in docs above), e.g. (assuming ltetrino static / top level class , constructor takes 2 int parameters): class<? extends ltetrino> cls = blockarray.get(0); // constructor constructor<? extends ltetrino>
