i need implement particular network graph in javascript. i've looked @ infovis toolkit , protovis, i'd have implement custom layout them , lot of custom code. i'm not sure add value. widget needs super efficient go on many highly visited webpages, don't want widget slowing down. the nodes of graph html-rich. dropdowns, input elements, popups, etc. div's make lot of sense each node. create divs in javascript using ajax read data server. implement layout mechanism in javascript , animate when adding/updating/deleting nodes through jquery. the thing can think of preventing me using jquery connections between nodes. how draw them? might able use raphael underneath nodes , coordinate between node positions , raphael, after briefly looking @ raphael, looks tricky. is there simpler way draw connections between nodes? ie support important @ least ie8. preferably lines can curved , patterned (dotted lines, double lines, etc) represent different types of

i'm building compiler , virtual machine executing byte code. language allows bind external c functions, may defined in external shared object, main compiler/vm binary (some essential language built-ins). i know can dynamically bind symbols within main executable dlopen(null, ...), not after run strip on binary. have following questions then: is there way on strip'ed binary? how portable feature across unix systems in general? is possible same trick on windows somehow? any alternatives ways of binding dynamically within main executable? use strip -d instead strip debug symbols. the dlopen(3) man page says: conforming posix.1-2001 describes dlclose(), dlerror(), dlopen(), , dlsym(). so, portable across *nix. windows uses loadlibrary() , getprocaddress() instead. no.

i'd code-analysis of javascript. i'd prefer operate on ast s or s-expression s. it's possible v8 engine builds this, though can't seem find documentation on how access information javascript context. i'd happy analysis in ruby, though way can think of doing write entire grammar in treetop or similar parser-generator. check out uglifyjs: https://github.com/mishoo/uglifyjs

i'd create extension visual studio 2010. functionalities need these: add context menu item project (when user right clicks project name in solution, he'll context item in list). when clicks, new winforms form appears, can input data, , option save data future reuse. when clicks ok on form i'll generate files , add files part of project rightclicked. the wscf.blue kind of behaviour want immitate in vs, it's source written in vs2008, , i'd use vs2010 extension options quite changed understand... i found resources on msdn, found confusing incomplete info (e.g. menuandcommands example). can shed light on how achieve i'm after? i don't know point out can specific examples of trying achieve. however, in following resources find complete , detailed information overall process, , achieve 1. , 2. vs 2010 package development – chapter 1: visual studio packages vs 2010 package development – chapter 2: commands, menus , toolbars

i running vanilla windows install on amazon ebs volume. computer takes 10 minutes boot, may understandable 2 reboots required. however, taking snapshot 10-15 minute process. can explain this? way speed up? bit surprised, because thought snapshots immediate replicas of running ebs volume, in case shouldn't take couple of seconds complete? i add console shows "snapshot" completed quickly. "ami" section seems take 10-20 minutes. what's difference? snapshot available use immediately, or need wait ami? from ebs product page : amazon ebs snapshots incremental backups, meaning blocks on device have changed since last snapshot saved. if have device 100 gbs of data, 5 gbs of data has changed since last snapshot, 5 additional gbs of snapshot data stored amazon s3. subsequent snapshots fast because changed blocks need saved. time takes scales amount of changes since last snapshot. is snapshot available use immediately, or

this question has answer here: python: pythonic way check if object number 10 answers in java numeric types descend number use (x instanceof number). what python equivalent? in more recent python versions (2.6+; in older versions you're pretty limited checking few hardcoded types), correct way test if variable instance of numbers.number : >>> import numbers >>> import decimal >>> [isinstance(x, numbers.number) x in (0, 0.0, 0j, decimal.decimal(0))] [true, true, true, true] this uses abcs , work build-in number-like classes, , third-party classes if worth salt (registered subclasses of number abc). however, in many cases shouldn't worry checking typed manually - python duck-typed , mixing compatible types works, yet barf error message when operation doesn't make sense ( 4 - "1" ), manually checking ne

i experiencing extremely wired wpf printdialog issue -- windows xp64 + vs2010. it pretty unbelievable very slow printdialog's .printableareawidth or .printableareaheight property. // see sample codes below - remember include "using system.windows.controls" printdialog pd = new printdialog(); double pw = pd.printableareawidth; // set break-point here, slow, why??? double ph = pd.printableareaheight; anyone has idea regarding this? appreciate thoughts! the printablearea refers actual printer in use - app has contact printer info, , guess that's reason why it's slow. shouldn't faster in winforms... if you'd want optimize, cache printer name , it's defaults , use instead of querying printer each time.

i know there couple of questions out there sharepoint development environments, wondering if there's shortcut if want develop relatively simple webpart. still have create virtual machine windows server, install sharepoint, sql server, wss etc., etc. or there easy way , running more quickly? in short, what's absolute minimum environment need develop webpart sharepoint 2007? unless willing put serious drawbacks (like not being able debug web part) have build virtual machine windows server. the minimum development environment : -windows server + sharepoint (wss or moss) + visual studio sql express installed visual studio. it take time setup first virtual machine, once have can , use every new project. while develop web part on own machine copying bunch of dlls , hacking up, not worth it. being able debug , deploy fast make development way faster. even if don't need it, still recommend install wspbuilder part of minimal environment. takes 2 minutes inst

i have page binds data db detailsview. i want use auto-generated update command. everything went ok, , updating successful, if remove field don't want have chance update, update command doesn't update! old values retain! i mean: if of fields present in detailsview, update ok, otherwise, update not update thing. i've tried mark fields don't want view "visible = 'false'" no results! how hide fields? thanks :) did try put field don't want update @ 'readonly = true' too? should mark them not updated.

how can jquery, in elegant way? apply z attribute (e.g.: red background) every children of div parent while position above given top-offset y . i've tried in different ways, i'm not happy of them... know there must short , elegant way it... since you're saying you've tried few ways, , you're looking more elegant, i'll assume have offset part worked out, , i'll go offset myself. modify part needed. elegance, create custom selector checking top offset: $.expr[':'].above = function(obj, index, meta, stack) { return $(obj).offset().top < meta[3]; } you query such: $('#myparentdiv').find('div:above(100)').css('background-color', 'red'); of course have been expressed as $('#myparentdiv div:above(100)').css('background-color', 'red'); or, pointed out in comments var y = 100; $('#myparentdiv div:above('+y+')').css('background-color&#

i'm curious performance benefits of using haseventlistener() on blindly dispatching event? for example, see in flex framework code snippets such following: // arraylist.setitemat() var hascollectionlistener:boolean = haseventlistener(collectionevent.collection_change); if (hascollectionlistener) { dispatchevent(new collectionevent(....)) } i assume infers there performance benefits of not dispatching event if no-one listening, versus blindly dispatching it, regardless of whether there listeners attached. however, doesn't seem make sense. surely listeners internally stored within sort of performant hashmap. i'd have thought checking see if listener exists performant iterating through empty array of listeners. therefore, why bother checking, , not blindly invoke dispatchevent method? original code sample clumsier had dispatched event. regards, marty as far can tell, running check redundant. if nobody listening, there nothing in listeners c

i need attach custom header web service client. purpose created partial class soaphttpclientprotocol class generated when added web reference. however, receiving runtime error when custom headers attached. works fine if custom headers not attached (when comment code attaches headers). if custom headers added receive following error during runtime: client found response content type of 'text/html; charset=utf-8', expected 'text/xml'. ideas? so here sample code: public partial class smartsws : system.web.services.protocols.soaphttpclientprotocol { private namevaluecollection _customheaders = new namevaluecollection(); protected override system.net.webrequest getwebrequest(system.uri uri) { // add authentication cookie // object cookiecontainer smartsivrsecuritymanager.setauthtoken(this); // set custom headers setcustomheaders(); httpwebrequest req = (httpwebrequest)base.getwebrequest(uri);

i've got attribute trait want set on basis of other class attributes. realy want default on attribute trait gets copy of class $self , not meta attribute. want in class: after 'build' => sub { $self = shift; $self->meta->get_attribute('id')->column_name( $self->_unique_key_name ); }; but, want keep attribute trait ro? possible. know mop allows 1 set value of class-attribute, can't figure out how set attribute on meta-attribute. this sounds odd design (why metaclass need instance of class describing?) -- can enough using metaclass of metaclass (remember moose meta classes bootstrapped using mop itself): $self->meta->meta->get_attribute("foo")->default($some_value); also remember defaults need wrapped in coderef if references themselves: $some_value = sub { $instance }; actually, won't

i have looked @ previous questions , nothing seems fit require. i working on scheduling system , client wants add timezones. so need able proform action @ specific date , time. lets chooses have alert @ following date/time: 25-12-2010 13:01:00 + / - timezone i need able store in mysql unix_timestamp, have been looking @ php's datetime , datetimezone has confused me more. i have looked @ strtotime also, unsure of best way work out date/time offset. just make sure we're on same page, want reiterate unix timestamp merely number of seconds since "unix epoch" (january 1, 1970). therefore simple math work on unix timestamps. there 2 ways go this; judging post you're confused you'd use. the first way easiest (and logical) way, , store offset (if have it, is) , multiply 3600 (1 hour in seconds), , add that value current unix timestamp final time of running. another way use datetime , datetimezone classes. how these 2 classes work, s

searched , searched , gave up. want more info on mysql table or better yet, list of tables in mysql database in descending/ascending order of create date. something : show tables mydb order create_date; donnie's answer did trick : select * information_schema.tables table_schema = 'dbname' order create_time desc; information_schema.tables queryable, doesn't have creation date. show table status return creation date information. can craft table name out of information_schema , call show table status on each.

is possible define margin text area? my wysiwyg editor places text within <div> tags in stead of giving linebreaks <br /> so thought giving <div> margin? is possible in css? , if yes how? many thanks. edit: can't define divs because gets no classes. example editor makes it: <div>lorem ipsum dolor sit amet, consectetur adipiscing elit. vestibulum egestas lacus libero, et pellentesque nisl. cras pharetra nunc sit amet urna vestibulum non ultricies metus malesuada. </div> <div>nulla tincidunt, neque @ blandit ultrices, massa odio pulvinar est, vel accumsan sapien justo sit amet lorem.</div> this looks like: lorem ipsum dolor sit amet, consectetur adipiscing elit. vestibulum egestas lacus libero, et pellentesque nisl. cras pharetra nunc sit amet urna vestibulum non ultricies metus malesuada. nulla tincidunt, neque @ blandit ultrices, massa odio pulvinar est, vel accumsan sapien justo sit amet lorem. but need

after interrupt execution in python interpreter (using ctrl-break in windows), can continue execution? if not, there other way interactively pause execution (so can view variable values), , continue? i prefer not use debugger because it's slower normal execution. i don't know if mean pdb debugger , if don't (and might helpful others here), can try: http://docs.python.org/library/pdb.html here's nice tutorial btw: http://onlamp.com/pub/a/python/2005/09/01/debugger.html

using library asm or cglib , there way add bytecode instructions class execute code whenever value of class field set? for example, let’s have class: public class person { bool dirty; public string name; public date birthdate; public double salary; } let’s section of code contains line: person.name = "joe"; i want instruction intercepted dirty flag set true . know possible setter methods -- person.setname (“joe”) -- class methods can modified bytecode manipulation, want same thing field . is possible, , if so, how ? edit i want avoid modifying code section accesses class, i'm looking way keep interception code part of person class. there pseudo-methods field access, similar properties in python classes? there 2 bytecodes updating fields: putfield , putstatic (see http://java.sun.com/docs/books/jvms/second_edition/html/instructions2.doc11.html ). these found in code using class, there's no

i have click function table row needs pass content of first 2 tds in row. // assign click handler rows $('#supporttables1 tr').click(function () { var firsttd = $(this).find('td').html(); //need next td. below line doesn't work. var secondtd = $(this).find('td')[1].html(); window.open('snglcontactlist.php'+'?search_word='+firsttd+'?list_name=secondtd); }); i can first td fine, i'm stumped on i'm sure profoundly simple matter of accessing second td (i've tried diferrent methods of setting it's index). the array notation [1] returns dom element, not jquery object, can't use .html() (a jquery method) on it. use jquery function .eq() elements instead: // assign click handler rows $('#supporttables1 tr').click(function () { var firsttd = $(this).find('td').eq(0).html(); var secondtd = $(this).find('td').eq(1).html(); window.open(&#
