c# code: public class xyz<t> t : class, new() in .net can force generic of class type using above syntex. my question how can achieve same using java? in java there's no constraint allows express type must have no-arg constructor. contrary .net in java t erased @ runtime .

this stupid question but, have method use make syntax of page little more easy read public void do(delegate method, dispatcherpriority priority = dispatcherpriority.normal) { this.window.dispatcher.begininvoke(method, dispatcherpriority.background); } then can write do(new action(() => { //dostuff() })); however, i'd move action method can write more simply: do(() => { //dostuff() })); but i'm bit sure how write contravariant parameter do method? lambdas untyped, not possible. if don't care method-arguments, appears case, why not change method signature : public void do(action method, dispatcherpriority priority = dispatcherpriority.normal) then, second sample work fine since compiler able implicitly convert lambda action . if want accept instance of any delegate-type represents method takes no arguments, you'll have stick

greetz fellows! i'm looking way log actions of cli script without losing time. did benchmarks , figured out echo ing someting after each action, script 2x slower , appending actions log file it'll 17x times slower. so, has solution? if using cli, guess can test this: your_script.php > /tmp/log.txt & inside your_script.php <? /* action */ echo date('r').some_action_1()."\n"; <-- bad # remark 1 echo date('r').some_action_2()."\n"; echo date('r'), some_action_1(), "\n"; <-- nice # remark 2 echo date('r'), some_action_2(), "\n"; ?> and monitor using tail -f /tmp/log.txt the reason remark 1 slow because function execute first, while remakr 2 not (output first)

(edit) 3) major reason me approaching in smaller chunk/recursive way need bind specific data each row. binding data wrong? there better way keep track of data

how access environment variables in vala? (as above) seems simple, can't find how g_getenv() mapped vala. the answer lies in bindings file. vala uses bindings (in .vapi files) binding constructs c language. in case can grep through glib-2.0.vapi (on system in /usr/share/vala-0.10/vapi ), , you'll see bound as: unowned string? glib.environment.get_variable(string name) it can quite useful have location of core vapi files handy, because if know c name of function can grep it.

(full disclosure: question offshoot of creating custom view ) you can create constructors beyond 3 standard ones inherited view add attributes want... mycomponent(context context, string foo) { super(context); // foo } ...but don't recommend it. it's better follow same convention other components. make component fle

there directory being served on net i'm interested in monitoring. contents various versions of software i'm using , i'd write script run checks what's there, , downloads newer i've got. is there way, wget or something, a directory listing. i've tried using wget on directory, gives me html. avoid having parse html document, there way of retrieving simple listing ls give? i figured out way it: $ wget --spider -r --no-parent http://some.served.dir.ca/ it's quite verbose, need pipe through grep couple of times depending on you're after, information there. looks prints stderr, append 2>&1 let grep @ it. grepped "\.tar\.gz" find of tarballs site had offer. note wget writes temporary files in working directory, , doesn't clean temporary directories. if problem, can change temporary directory: $ (cd /tmp && wget --spider -r --no-parent http://some.served.dir.ca/)

we have nhibernate app migrating sql server oracle. our optimistic concurrency implemented via <timestamp name="version"> mapping element. the data type of corresponding version column in oracle date . after save object, in-memory c# object left timestamp value in milliseconds (e.g. 12:34:56.789) while value in database precise second (e.g. 12:34:56). thus, if attempt save object 2nd time, stalestateexception because 2 values not match. i attempted fix altering data type of version column timestamp(3) . unfortunately, c# object , db value still off 1 millisecond (e.g. 12:34:56.789 vs 12:34:56.788), 2nd attempt save object still causes stalestateexception. what can create working <timestamp> mapping oracle column of type date or timestamp same object can saved multiple times? thanks. -- brian timestamp(7) has correct precision match .net datetime class , fixed problem.
