monads explained in turns of return , bind . however, gather can implement bind in terms of join (and fmap ?) in programming languages lacking first-class functions, bind excruciatingly awkward use. join , on other hand, looks quite easy. i'm not sure understand how join works, however. obviously, has [haskell] type join :: monad m => m (m x) -> m x for list monad, trivially , concat . general monad, what, operationally, method do? see type signatures, i'm trying figure out how i'd write in, say, java or similar. (actually, that's easy: wouldn't. because generics broken. ;-) in principle question still stands...) oops. looks has been asked before: monad join function could sketch out implementations of common monads using return , fmap , join ? (i.e., not mentioning >>= @ all.) think perhaps might sink in dumb brain... without plumbing depths of metaphor, might suggest read typical monad m "strategy produce a...

i'm developing system collect user activities samples (opened window, scrolls, enter page, leave page, etc.) , i'm looking best way store these samples , query it. i prefer smart can execute sql-like group queries (for example give me window open events grouped date , hour), , of course flexible enough in case i'll need add columns in future. i'm trying avoid thinking queries might need , save aggregated version of data time, since i'd drill-downs. (for example, count window open events date , time, , see event in each time-frame, or change unique userid). thanks. ps - use mysql task, data expected grow rapidly. i've experimented mongodb well. i believe mongodb can solution. first of it's designed hold big data , it's easy use , scale (replica set or sharding). expression language solid. mean it's not powerful sql, still enough. here link mapping sql command mongodb. there other alternatives, think or complex or expression lan...

assuming you're in single-threaded process, , relevant signal not blocked or ignored, guaranteed that: kill(getpid(), sig); will result in signal being delivered before next line of code executed? in particular, if signal 1 there no handler , whole default action terminate process (e.g. sigterm, sigalrm), guaranteed next line of code won't executed? i had assumed (at least on linux) answer "yes", because thought before returning syscall kernel check see if there pending signals , deliver them if so. think have observed (when run on heavily-loaded, multi-core system) not case, though hard reproduce , i'd appreciate confirmation i'm not seeing things.

can assignment operation between 2 istream_iterators? if behaviour, i.e. both iterators point same location in file, i.e. 2 pointers same line in file? if so, can increment 1 iterator, read lines, , assign other iterator , again start reading lines same location earlier? basically want write program simulates loop. should happen while parsing file. istream_iterators input iterators , not forward iterators . means single-pass iterators, opposed multi-pass iterators: there no way go in sequence, or iterate sequence more once.

i have table , change image in <td> when click must url of image determine before. that url of image type link of page(for example click on img) index.html?type=dog then script read variables link. create variable script. type = httpgetvars["type"] now when click on img of cat, script should replace cat .png dog .png , tried in way. <img src="cat.png" onclick="document.write("<img src=\""+ type + ".png\">); <img id="foo" src="cat.png /> give <img> id - foo example than: document.getelementbyid('foo').src = type +".png"; you change existing <img> src new image.

backend default { .host = "localhost"; .port = "8080"; } at varnish config, port should assigning? i'm using apache on backend listening 1740 , nginx listening 80 proxy_pass upstream 127.0.0.1:1740 . why not nginx + varnish? nginx , apache both webserver, of course can use nginx proxy_pass... if same server ditch apache or nginx... choose one. in case "varnish web application accelerator. install in front of web application , speed significantly." (copy paste form home page @ site) so think first should decide if want nginx or apache has you're web server.

i confused how following works in mysql. in queries below, first select returns rows table2 while second select returns none of rows. there explanation of how null works not in operator. there documentation explains this? create table table1 ( id int unsigned not null auto_increment, primary key (id) ); create table table2 ( id int unsigned not null auto_increment, table1_id int unsigned, primary key (id) ); insert table2 (id, table1_id) values (1, null); select count(*) table2 table1_id not in (select id table1); +----------+ | count(*) | +----------+ | 1 | +----------+ insert table1 (id) values (1); select count(*) table2 table1_id not in (select id table1); +----------+ | count(*) | +----------+ | 0 | +----------+ the reason according sql specification, foo in(a,b,c) translates ( foo = or foo = b or foo = c ) . thus, if have foo in(null, 1, 2) foo = null or foo = 1 or foo = 2 . since foo = null unknown , evaluated false purp...

in older (1.x.x) versions of groovy can add constructors using metaclass.constructor example.metaclass.constructor << { string arg0 -> new example(arg0, "") } is there way register constructors using new groovy 2.0 extension modules? this seems work: define extension class normal groovy 2 , add constructors in static initialiser public class examplehelper { static { example.metaclass.constructor << { string arg0 -> new example(arg0, "") } } } not know of... you add static factory method example class ie: class exampleextensionstatic { public static example newinstance( example type, string arg0 ) { new example( arg0, '' ) } } then (after adding link class in staticextensionclasses field of org.codehaus.groovy.runtime.extensionmodule file), do: example.newinstance( 'arg0' ) this worth asking on mailing list see if constructors worth adding module extension system.

i have piece of code wherein make server call , based on response play sound. now, not work when application in background or devicei locked. is there way can execute piece of code (server call , response handling) if app in background or device locked? there no general solution, design. (apple not want have potentially cpu- , power-intensive process running in background , degrading user experience.) there few limited-case options available: you said want play sound. if mean "play music" or such streaming, there audio background task application can register perform. note must actually streaming audio; apple rightfully frowns upon apps try use approach circumvent general-case prohibition , reject app store submission accordingly. you can invert scenario , have server send push notification through apple push notification service . depending on user's settings, alert, badge, or sound can result. might best fit if aren't streaming audio. ...

i have question public , private classes in java. example, if have public method inside of private class, can public method accessed other public/private classes? in advance. in order able invoke method inside class, method invocation must have access class itself. therefore, methods of class inside of private class defined have access public method, , methods of other classes not have access. of course if private class inherits public class or implements public interface, methods of base class or interface visible everyone.
