i have field text field containing dates. have checkbox named "delivered" if text field contains date, "delivered" checkbox value "true" / ticked. if text field isnull, checkbox value must "false" / not ticked i have tried following in query expression builder of checkbox: iif([datefield]="";false;true) but keep getting error expression being built incorrectly? you trying store calculation/dependent value in table based on field in same table, not advisable , should not carried forward. calculations should done when , required, display on forms, query export or reports show. more info on calculation field available here : http://allenbrowne.com/casu-14.html if want can create update query as, update tablename set deliveredfieldname = iif(len(datefieldname & '') = 0, false, true);

why numpy.sum , numpy.prod function return int32 when input list of int, , int64 if it's generator same list? what's best way coerce them use int64 when operating on list? e.g. sum([x x in range(800000)]) == -2122947200 sum((x x in range(800000))) == 319999600000l python 2.7 you using numpy.sum instead of built-in sum , side effect of from numy import * . advised not so, cause no end of confusion. instead, use import numpy np , , refer numpy namespace short np prefix. to answer question, numpy.sum makes accumulator type same type of array. on 32-bit system, numpy coerces list int32 array, causes numpy.sum use 32-bit accumulator. when given generator expression, numpy.sum falls calling sum , promotes integers longs. force use of 64-bit accumulator array/list input, use dtype parameter: >>> np.sum([x x in range(800000)], dtype=np.int64) 319999600000

so far seems answer no. which unfortunate given how more visually noisy code becomes shared_ptrs on place. with c++11, 1 possible way use aliases (which cleaner imo macros). e.g. shared pointers, do: template<typename t> using shared = std::shared_ptr<t>; then, use following: shared<int> myint; // in fact std::shared_ptr<int> edit: live example .

my workflow follows, using celery rabbitmq step 1. large file broken multiple parts(let's 4), , put mq, step 2. workers(let's 2) process files , store somewhere. now, question , have task complete, , joining files, ofcourse synchronous task, i.e. parts of file should have been processed, so, do through celery make joining task dependent on step 2. do create separate application join files, somehow receive status of these workers, whether have finished processing files. or put joining of files task in mq, again (block waiting) assure that, parts processed, n join files, (this again can done worker) which approach achievable? make these 2 tasks interdependent yes 2 celery applications/tasks can interdependent. to achieve goal use celery canvas: http://celery.readthedocs.org/en/latest/userguide/canvas.html , more precisly 'chords' a chord task executes after of tasks in group have finished executing. from celery import chord @task de...

i know monads , how use them. don't understand what makes, let's say, option monad? in haskell monad maybe monad because it's instantiated monad class (which has @ least 2 necessary functions return , bind makes class monad , indeed, monad). but in scala we've got this: sealed abstract class option[+a] extends product serializable { ... } trait product extends equals { ... } nothing related monad. if create own class in scala, monad default? why not? monad concept, abstract interface if will, defines way of composing data. option supports composition via flatmap , , that's pretty needed wear "monad badge". from theoretical point of view, should also: support unit operation ( return , in haskell terms) create monad out of bare value, in case of option some constructor respect monadic laws but not strictly enforced scala. monads in scala looser concept in haskell, , approach more practical. thing monads relevant...
