in chapter 6 of learn haskell , following function introduced: zipwith' :: (a -> b -> c) -> [a] -> [b] -> [c] zipwith' _ [] _ = [] zipwith' _ _ [] = [] zipwith' f (x:xs) (y:ys) = f x y : zipwith' f xs ys the author gives couple examples of use found easy enough follow. one: ghci> zipwith' (zipwith' (*)) [[1,2,3],[3,5,6],[2,3,4]] [[3,2,2],[3,4,5],[5,4,3]] which outputs [[3,4,6],[9,20,30],[10,12,12]] is example of lazy evaluation? tried translate zipwith' scheme (see below). got working "easy" examples, not last one, makes me think haskell's laziness might making difference. (define zipwith (lambda (f lista listb) (cond ((null? lista) (quote ())) ((null? listb) (quote ())) (else (cons (f (car lista) (car listb)) (zipwith f (cdr lista) (cdr listb))))))) no, although example evaluated lazily (like other function in haskell), behaviour doesn't depend on that. on finite lists ...

i've got c# (.net 3.5) application extensively use log4net. log4net configuration resides in app.config file. configuration done using [assembly: xmlconfigurator(watch = true)] in assemlyinfo.cs app uses single application-wide logger instance, instantiated in static constructor of logger wrapper class: public class logger{ //.... private static readonly ilog logger; static logger() { logger = logmanager.getlogger(assembly.getentryassembly().getname().name); appdomain.currentdomain.unhandledexception += onunhandledexception; } //.... } the app designed run on distant server, scheduler, no human presense, alone in dark. :) problem is, in case of missing config file silently crashes (no log4net config => no logging). are there way check if there appenders in config, , if not - programmatically add kind of fallback appender. i'm rather new log4x loggers family, so, if i'm asking trivial - please kind, log4net documen...

one way solve optimisation problems use smt solver ask whether (bad) solution exists, progressively add tighter cost constraints until proposition no longer satisfiable. approach discussed in, example, http://www.lsi.upc.edu/~oliveras/espai/papers/sat06.pdf , http://isi.uni-bremen.de/agra/doc/konf/08_isvlsi_optprob.pdf . is approach efficient , though? i.e. solver re-use information previous solutions when attempting solve additional constraints? the solver can reuse lemmas learned when trying solve previous queries. keep in mind in z3 whenever execute pop lemmas (created since corresponding push ) forgotten. so, accomplish must avoid push , pop commands , use "assumptions" if need retract assertions. in following question, describe how use "assumptions" in z3: soft/hard constraints in z3 regarding efficiency, approach not efficient 1 every problem domain. on other hand, can implemented on top of smt solvers. moreover, pseudo-boolean solvers ...

is there easy way of running jquery script on 1 specific form , it's children without effecting other forms on website. at moment use child selector other selector, there command following selectors match within children of form? thanks you can use find : $('#myform').find('.otherclass').css({color: 'red'}) the selector .otherclass searched inside #myform . and small refactoring: var $f = function(selector) { return $('#myform').find(selector); } you can use: $f('.otherclass').css({color: 'red'}) to scoped version of jquery function.

i trying learn best way write queries. understand importance of being consistent. until now, have randomly used single quotes, double quotes, , backticks without real thought. example: $query = 'insert table (id, col1, col2) values (null, val1, val2)'; also, in above example, consider "table," "col[n]," , "val[n]" may variables. what standard this? do? i've been reading answers similar questions on here 20 minutes, seems there no definitive answer question. backticks used table , column identifiers, necessary when identifier mysql reserved keyword , or when identifier contains whitespace characters or characters beyond limited set (see below) recommended avoid using reserved keywords column or table identifiers when possible, avoiding quoting issue. single quotes should used string values in values() list. double quotes supported mysql string values well, single quotes more accepted other rdbms, habit use single quot...
