  • What's all this fuss about?

    - by atch
    Hi guys, At the beginning I want to state that it is not my intention to upset anyone who uses/like language other than C++. I'm saying that due to the fact that on one forum everytime when I've tried to ask questions of similiar nature I was almost always accused of trying to create a raw. Ok that's having done this is my question: I don't understand why java/c# creators thought/think that having something like vm and having source code compiled to bytecode instead of native code is in a long run any advantage. And why having function compiled for a first time when they are invoked is any advantege? And what's the story about write once run everywhere? When I think about the business of having something written once and it can run everywhere - well in theory this is all well. But I know for a fact that in practice it doesn't look that well at all. It is rather like write once test everywhere. And why would I preffer something to be compiled on runtime instead of compiletime. If I would have to wait even one hour longer for program to be installed once and for all and all the compilation would be done and nothing would be compiled after that I would preffer that. And I don't really know how it works in the real world (I'm a student never worked in IT business) but for example if I have working program written in C++ for Windows and I have wish to move it to another platform wouldn't I have to take my source code and compile it on desired machine? So in other words isn't that rather problem of having compiler which will compile source code on different machines (as far as I'm concerned there is just one C++ and source code will look identical in every machine). And last but not least if you think about it how many programs they are which are really word porting? I personnally can think of 3 maybe four.

  • Marshalling C# com items when using recursion

    - by Kevin
    I am using the SourceSafe COM object (SourceSafeTypeLib) from C# to automate a SourceSafe recursive get (part of a larger build process). The recursive function is shown below. How do I ensure that all the COM objects created in the foreach loop get released correctly? /// <summary> /// Recursively gets files/projects from SourceSafe (this is a recursive function). /// </summary> /// <param name="vssItem">The VSSItem to get</param> private void GetChangedFiles(VSSItem vssItem) { // 'If the object is a file perform the diff, // 'If not, it is a project, so use recursion to go through it if(vssItem.Type == (int)VSSItemType.VSSITEM_FILE) { bool bDifferent = false; //file is different bool bNew = false; //file is new //Surround the diff in a try-catch block. If a file is new(doesn't exist on //the local filesystem) an error will be thrown. Catch this error and record it //as a new file. try { bDifferent = vssItem.get_IsDifferent(vssItem.LocalSpec); } catch { //File doesn't exist bDifferent = true; bNew = true; } //If the File is different(or new), get it and log the message if(bDifferent) { if(bNew) { clsLog.WriteLine("Getting " + vssItem.Spec); } else { clsLog.WriteLine("Replacing " + vssItem.Spec); } string strGetPath = vssItem.LocalSpec; vssItem.Get(ref strGetPath, (int)VSSFlags.VSSFLAG_REPREPLACE); } } else //Item is a project, recurse through its sub items { foreach(VSSItem fileItem in vssItem.get_Items(false)) { GetChangedFiles(fileItem); } } }

  • DotNetOpenAuth OpenID on ISA 2006 Reverse Proxy problem

    - by userb00
    I am trying to host my site that uses DotNetOpenAuth (OpenID) behind ISA 2006 (reverse proxy), and after it authenticated with a provider (such as Google), and it returns with a URL with %253A in the URL. However, ISA HTTP filter rejects the request. What I need to do is, on ISA web publishing rule, right click config HTTP policy properties uncheck "Verify Normalization" and it worked. Is this a problem on ISA 2006 generally? Are other firewalls having similar problems? Or, is it an OpenID or DotNetOpenAuth issue? Is it safe to disable Normalization checking on ISA? According to MSDN, quote "Web servers receive requests that are URL encoded. This means that certain characters may be replaced with a percent sign (%) followed by a particular number. For example, %20 corresponds to a space, so a request for http://myserver/My%20Dir/My%20File.htm is the same as a request for http://myserver/My Dir/My File.htm. Normalization is the process of decoding URL-encoded requests. Because the % can be URL encoded, an attacker can submit a carefully crafted request to a server that is basically double-encoded. If this occurs, Internet Information Services (IIS) may accept a request that it would otherwise reject as not valid. When you select Verify Normalization, the HTTP filter normalizes the URL two times. If the URL after the first normalization is different from the URL after the second normalization, the filter rejects the request. This prevents attacks that rely on double-encoded requests. Note that while we recommend that you use the Verify Normalization function, it may also block legitimate requests that contain a %."

  • Attempting to find a formula for tessellating rectangles onto a board, where middle square can't be

    - by timemirror
    I'm working on a spatial stacking problem... at the moment I'm trying to solve in 2D but will eventually have to make this work in 3D. I divide up space into n x n squares around a central block, therefore n is always odd... and I'm trying to find the number of locations that a rectangle of any dimension less than n x n (eg 1x1, 1x2, 2x2 etc) can be placed, where the middle square is not available. So far I've got this.. total number of rectangles = ((n^2 + n)^2 ) / 4 ..also the total number of squares = (n (n+1) (2n+1)) / 6 However I'm stuck in working out a formula to find how many of those locations are impossible as the middle square would be occupied. So for example: [] [] [] [] [x] [] [] [] [] 3 x 3 board... with 8 possible locations for storing stuff as mid square is in use. I can use 1x1 shapes, 1x2 shapes, 2x1, 3x1, etc... Formula gives me the number of rectangles as: (9+3)^2 / 4 = 144/4 = 36 stacking locations However as the middle square is unoccupiable these can not all be realized. By hand I can see that these are impossible options: 1x1 shapes = 1 impossible (mid square) 2x1 shapes = 4 impossible (anything which uses mid square) 3x1 = 2 impossible 2x2 = 4 impossible etc Total impossible combinations = 16 Therefore the solution I'm after is 36-16 = 20 possible rectangular stacking locations on a 3x3 board. I've coded this in C# to solve it through trial and error, but I'm really after a formula as I want to solve for massive values of n, and also to eventually make this 3D. Can anyone point me to any formulas for these kind of spatial / tessellation problem? Also any idea on how to take the total rectangle formula into 3D very welcome! Thanks!

  • How does 'lazy' work?

    - by Matt Fenwick
    What is the difference between these two functions? I see that lazy is intended to be lazy, but I don't understand how that is accomplished. -- | Identity function. id :: a -> a id x = x -- | The call '(lazy e)' means the same as 'e', but 'lazy' has a -- magical strictness property: it is lazy in its first argument, -- even though its semantics is strict. lazy :: a -> a lazy x = x -- Implementation note: its strictness and unfolding are over-ridden -- by the definition in MkId.lhs; in both cases to nothing at all. -- That way, 'lazy' does not get inlined, and the strictness analyser -- sees it as lazy. Then the worker/wrapper phase inlines it. -- Result: happiness Tracking down the note in MkId.lhs (hopefully this is the right note and version, sorry if it's not): Note [lazyId magic] ~~~~~~~~~~~~~~~~~~~ lazy :: forall a?. a? -> a? (i.e. works for unboxed types too) Used to lazify pseq: pseq a b = a `seq` lazy b Also, no strictness: by being a built-in Id, all the info about lazyId comes from here, not from GHC.Base.hi. This is important, because the strictness analyser will spot it as strict! Also no unfolding in lazyId: it gets "inlined" by a HACK in CorePrep. It's very important to do this inlining after unfoldings are exposed in the interface file. Otherwise, the unfolding for (say) pseq in the interface file will not mention 'lazy', so if we inline 'pseq' we'll totally miss the very thing that 'lazy' was there for in the first place. See Trac #3259 for a real world example. lazyId is defined in GHC.Base, so we don't have to inline it. If it appears un-applied, we'll end up just calling it. I don't understand that because it refers to lazyId instead of lazy. How does lazy work?

  • Advice for Windows XP Scripting, WSH versus PowerShell

    - by Greg Graham
    After much experience scripting in the Unix/Linux open-source world, using languages such as Bourne Shell, Perl, Python, and Ruby, I now find myself needing to do some Windows XP admin scripting. It appears that the legacy environment is Windows Script Host (WSH), which can use various scripting languages, but the primary language is VBScript, and is based on COM objects. However, the future appears to be Windows PowerShell, which is based on .NET. I haven't done Basic since Applesoft in the 70s, so I'm not keen on learning VBScript, although I did learn enough to write a small script to mount network drives. If I'm going to spend time to really learn this, I'm leaning towards investing my time in the .NET PowerShell environment, if it truly is the future. I did some C# Windows Forms programming a couple of years ago, so I have some exposure to .NET, which also makes PowerShell attractive. Understanding that no one has a crystal ball to predict the future of Microsoft, I would like hear from anyone who is a PowerShell user and thinks it's worthwhile, or if there is anyone that knows of serious drawbacks to PowerShell, and recommends that I stay away from it. Update: I ended up using WSH/VBScript for a particular script that I am installing as a startup script on user's Windows XP workstations. All I have to do is copy it to their Startup folder, and I'm done. However, I only learned enough WSH to accomplish this one job. I am glad to see that PowerShell is the future, and when I have more complicated scripting tasks, I'll to turn PowerShell.

  • Postback event not firing on FIRST button click..

    - by ClarkeyBoy
    Hi, I have a form which accepts two arguments. The first one is mode - this is either view, new or edit. If it is new then the second argument is type - this is either range, collection or design. When set to new, and the type is valid, a new instance of that type is created and the data from the form is added to it. The item (range, collection or design) then validates the data. If any of the data is invalid then it throws an error, and this error is displayed at the top of the form telling the user why it is invalid. A variable, _Databind, is set to false so that it does not change the data input by the user (in the form fields). The button used to submit the button is called btnSave, and is created in the html source. The click event is wired up in the form Protected Sub Blah(sender, e) Handles btnSave.Click. Strangely, whenever I edit an item that already exists the form submits fine the first time - the click event is fired. However when in "new" mode I have to click the button twice to fire the event. It also blanks all the form fields out on first click. I have even put a Response.Write("Hello World") line at the start of the click event - this is not being output on first click when adding a new item either. It is on first load when the mode is set to edit however. Does anyone have any ideas as to what is causing it to behave this way? Thanks in advance for any help. Regards, Richard

  • Java performance problem with LinkedBlockingQueue

    - by lofthouses
    Hello, this is my first post on stackoverflow...i hope someone can help me i have a big performance regression with Java 6 LinkedBlockingQueue. In the first thread i generate some objects which i push in to the queue In the second thread i pull these objects out. The performance regression occurs when the take() method of the LinkedBlockingQueue is called frequently. I monitored the whole program and the take() method claimed the most time overall. And the throughput goes from ~58Mb/s to 0.9Mb/s... the queue pop and take methods ar called with a static method from this class public class C_myMessageQueue { private static final LinkedBlockingQueue<C_myMessageObject> x_queue = new LinkedBlockingQueue<C_myMessageObject>( 50000 ); /** * @param message * @throws InterruptedException * @throws NullPointerException */ public static void addMyMessage( C_myMessageObject message ) throws InterruptedException, NullPointerException { x_queue.put( message ); } /** * @return Die erste message der MesseageQueue * @throws InterruptedException */ public static C_myMessageObject getMyMessage() throws InterruptedException { return x_queue.take(); } } how can i tune the take() method to accomplish at least 25Mb/s, or is there a other class i can use which will block when the "queue" is full or empty. kind regards Bart P.S.: sorry for my bad english, i'm from germany ;)

  • Android: Determine when an app is being finalized vs destroyed for screen orientation change

    - by Matt
    Hi all, I am relatively new to the Android world and am having some difficultly understanding how the whole screen orientation cycle works. I understand that when the orientation changes from portrait to landscape or vice versa the activity is destroyed and then re-created. Thus all the code in the onCreate function will run again. So here's my situation: I have an app that I am working on where it logs into a website, retrieves data, and displays it to the user. While this is all done in background threads, the code that starts these threads is in the onCreate function. Now, the problem lies in that whenever the user changes the screen orientation, the app will log in, retrieve the data, and display it to the user again. What I would like to do is set a boolean that tells the app if it is logged in or not so it knows whether or not it must log in when the onCreate function is called. So long as the app is in memory the HttpClient will exist and contain the cookies from logging the user in but when the app is killed by the system those will go away. So I would assume that I need to do something like setting the logged in boolean to false when the app is killed but since onDestroy is called when the screen is rotated how is this possible? I also looked into the finalize function and isFinishing() but those seem to not be working. Shorter version: How can I distinguish between when an app is being killed from memory from when an activity is being rotated and different code for each event? Any help or a point in the right direction is greatly appreciated. Thank you!

  • Strange error coming from ActiveRecord (probably)

    - by artemave
    My development environment: Ubuntu 9 Ruby 1.9.1/1.8.7 (rvm) Rails 2.3.5 Mysql 5.0 Apache Passenger Below is the part of the program flow to represent the issue. Request comes: #action def create begin @report = Report.new(params[:report]) ... rescue LocationNotFound => e ... end end Report constructor: class Report attr_accessor :locations def initialize(params = {}) @locations = params[:locations] ? fetch_locations(params[:locations]) : [] end ... end fetch_locations: def fetch_locations(loc_names) Rails.logger.debug "LOC_NAMES: " + loc_names.inspect ls = Location.find(:all, :conditions => [ # line 57 "locations.name in (#{loc_names.map{'?'}.join(',')})", *loc_names ], :include => [:sample_summaries, :samples]) # loc_names will never be empty ... end Location model: class Location < ActiveRecord::Base has_many :sample_summaries has_many :samples, :through => :sample_summaries ... end Now, the first time (after passenger restart) this runs fine and does the job. Most of the consequent times I get the error: Mar-11 11:01:00 #15098 DEBUG: LOC_NAMES: ["Moscow, RF", "London, UK"] Mar-11 11:01:00 #15098 DEBUG: Location Load (0.0ms) SELECT * FROM `locations` WHERE (locations.name in ('Moscow, RF','London, UK')) Mar-11 11:01:00 #15098 DEBUG: SampleSummary Load (0.0ms) SELECT `sample_summaries`.* FROM `sample_summaries` WHERE (`sample_summaries`.location_id IN (1,3)) Mar-11 11:01:00 #15098 DEBUG: SampleSummary Columns (0.0ms) SHOW FIELDS FROM `sample_summaries` Mar-11 11:01:00 #15098 FATAL: NoMethodError (You have a nil object when you didn't expect it!

  • JQuery DatePicker - pop calendar dialog on 'OnSelect' of another datepicker

    - by sajanyamaha
    I have two JQuery datepickers to select 'StartDate' and 'EndDate'.My requirement is to automatically popup the end date calendar after startDate has been selected. I have tried all the steps in COMMENTED HERE. The code here succesfully triggers the focus of 'EndDate' calendar,but it displays for a second and hides off. $(document).ready(function() { //Runs when tab is loaded var dateFormat = "dd/mm/yy"; var today=new Date(); today.setMonth(today.getMonth()-1); $("#ctl00_ContentPlaceHolder1_datepicker1").datepicker({ minDate: 0, dateFormat:dateFormat, //maxDate: '+12M +31D', onSelect: function(dateText, inst){ var the_date = new Date($.datepicker.parseDate(dateFormat,dateText)); //var end=(the_date.getDate()+1) + '/' + (the_date.getMonth()+1) + '/' + the_date.getFullYear(); $("#ctl00_ContentPlaceHolder1_datepicker2").datepicker('option', 'minDate', the_date); // TRIED ALL THESE //document.getElementById('ui-datepicker-div').style.display = 'block'; //document.getElementById('ui-datepicker-div').style.left = '635.5px'; //$("#ctl00_ContentPlaceHolder1_datepicker2").datepicker("show"); //$("#ctl00_ContentPlaceHolder1_datepicker2").datepicker(); //$("#ctl00_ContentPlaceHolder1_datepicker2").focus(); //$('#foo').slideUp(300).delay(800).fadeIn(400); //$("#ctl00_ContentPlaceHolder1_datepicker2").trigger("focus"); $('#ctl00_ContentPlaceHolder1_datepicker2').focus(); } }); $("#ctl00_ContentPlaceHolder1_datepicker2").datepicker({ //maxDate: '+12M +31D', dateFormat:dateFormat, onSelect: function(dateText, inst){ } }); });

  • What are basic programs like, recursion, Fibonacci, small trick programs?

    - by Mike
    This question may seem daft (I'm a new to 'programming' and should probably stop if this is the type of question I'm required to ask)... What are: "basic programs like, recursion, fibonacci, factorial, string manipulation, small trick programs"? I've recently read Coding Horror - the non programmer and followed the links to Kegel and How to get hired. Then I delved through some similar questions here (hence the block quote) and I realised that as a fully fledged non-programmer I probably wouldn't know if I knew recursion (or any of the others) because I wouldn't know what it looked like, or why it was used, and what the results would look like after it was used. I suppose I'm trying to get a picture of "the basics". What the principles are and why we learn them - where they'll be used and what result/s your looking for. If they'll be used as an interview question during my first interview sometime in 2020 I would like to look less ignorant than those 199 out of 200 who just don't know the how, or the why, of programming. As always...I'll get my coat. Thanks Mike

  • Converting a size_t into an integer (c++)

    - by JeanOTF
    Hello, I've been trying to make a for loop that will iterate based off of the length of a network packet. In the API there exists a variable (size_t) by event.packet-dataLength. I want to iterate from 0 to event.packet-dataLength - 7 increasing i by 10 each time it iterates but I am having a world of trouble. I looked for solutions but have been unable to find anything useful. I tried converting the size_t to an unsigned int and doing the arithmetic with that but unfortunately it didn't work. Basically all I want is this: for (int i = 0; i < event.packet->dataLength - 7; i+=10) { } Though every time I do something like this or attempt at my conversions the i < # part is a huge number. They gave a printf statement in a tutorial for the API which used "%u" to print the actual number however when I convert it to an unsigned int it is still incorrect. I'm not sure where to go from here. Any help would be greatly appreciated :)

  • Javascript :(….. Oh!! So its jquery? Now what?? I’m a C# Guy

    - by Shekhar_Pro
    Hi guys I want you to Guide me here. This other day I was working out some AJAX for my ASP.Net website and handling client side code in Java was taking the hell out of me. Then I got my hands on this Book jQuery In Action 2nd Edition and solved my problem with the help of Example code in the book. Now as I checked the contents I got an overview that whatever I had ever thought of doing can be done by this jQuery so easily and quite cleanly. I am actually pretty new to web development (say abt 4months ) and from C# world where we have cool libraries and Simple and Elegant coding style. (yeah including those generic, Ienumerable, lambadas, chained statements.. you got it…) and you know what you’re doing when writing some code. And we have so great IntelliSense to care., and above all we have everything Strongly Typed. But in Javascript everything is so messy.. . (and I don’t know why they are not properly indented.. see page source ) Now tell me what should I do, go straight with jQuery or should I first learn Javascript (like a disciplined boy…I even have a book for that too… got in gift :) …. ) I have seen Is it a good idea to learn JavaScript before learning jQuery? but remember I have already got a project on my hand…

  • Using MSADO15.DLL and C++ with MinGW/GCC on Windows Vista

    - by Eugen Mihailescu
    INTRODUCTION Hi, I am very new to C++, is my 1st statement. I have started initially with VC++ 2008 Express, I've notice that GCC becomes kind of standard so I am trying to make the right steps event from the beginning. I have written a piece of code that connects to MSSQL Server via ADO, on VC++ it's working like a charm by importing MSADO15.dll: #import "msado15.dll" no_namespace rename("EOF", "EndOfFile") Because I am going to move from VC++ I was looking for an alternative (eventually multi-platform) IDE, so I stick (for this time) with Code::Block (I'm using last nightly buil, SVN 6181). As compiler I choose to use GCC 3.4.5 (ported via MinGW 5.1.6), under Vista. I was trying to compile a simple "hello world" application with GCC that use/import the same msado15.dll (#import "c:\Program Files\Common Files\System\ADO\msado15.dll" no_namespace rename("EOF", "EndOfFile")) and I was surprised to see a lot of compile-time errors. I was expected that the #import compiler's directive will generate a library from "msado15.dll" so it can link to it later (link-edit time or whatever). Instead it was trying to read it as a normal file (like a header file,if you like) because it was trying to interprete each line in the DLL (which has a MZ signature): Example: Compiling: main.cpp E:\MyPath\main.cpp:2:64: warning: extra tokens at end of #import directive In file included from E:\MyPath\main.cpp:2: c:\Program Files\Common Files\System\ADO\msado15.dll:1: error: stray '\144' in program In file included from E:\MyPath\main.cpp:2: c:\Program Files\Common Files\System\ADO\msado15.dll:1:4: warning: null character(s) ignored c:\Program Files\Common Files\System\ADO\msado15.dll:1: error: stray '\3' in program c:\Program Files\Common Files\System\ADO\msado15.dll:1:6: warning: null character(s) ignored c:\Program Files\Common Files\System\ADO\msado15.dll:1: error: stray '\4' in program ... and so on. MY QUESTION Well, it is obvious that under this version of GCC the #import directive does not do the expected job (perhaps #import is not supported anymore by GCC), so finally my question: how to use the ADO to access MSSQL database on a C++ program compiled with GCC (v3.4.5)?

  • 2-step user registration with Django

    - by David S
    I'm creating a website with Django and want a fairly common 2-step user registration. What I mean by this is that the user fills in the some basic user information + some application specific information (sort of like a coupon value). Upon submit, an email is sent to ensure email address is valid. This email should contain a link to click on to "finish" the registration. When the link is clicked, the user is marked as validated and they are directed to a new page to complete optional "user profile" type information. So, pretty basic stuff. I have done some research and found django-registration by James Bennett. I do know who James is and have seen him at PyCons and DjanoCons in the past. There is obviously very few people in the world that know Django better than James (so, I know the quality of the code/app is good). But, it almost seems like a bit of over kill. I've read through the docs and was a bit confused (maybe I'm just being a bit dense today). I believe that if I do use django-registration, I will need to have some custom forms, etc. Is there anything else out there I should evaluate? Or are there any good tutorials or videos on using django-registration? I've done a bit of googling, but haven't found anything. But, I suspect that it might be a case of a lot of very common words that don't really find what you are looking for (django user registration tutorial/example). Or is just a case where it would be just about as easy to build your own solution with Django forms, etc? Here is the tech stack I'm using: Python 2.7.2 Django 1.3.1 PostgreSQL 9.1 psycopg2 2.4.1 Twitter Bootstrap 2.0.2

This is the code for the Master Template, can anyone suggest or help me out here? I'd buy a book and read more, but I have to do this for the next 12 hours. <%@ Master Language="C#" AutoEventWireup="true" CodeFile="Public.master.cs" Inherits="Public" %> <%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="cc2" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <%--<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> --%><html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title></title> <%--<link href="favicon.ico" rel="Shortcut Icon" type="image/x-icon" />--%> <link href="<%= Server.MapPath("~/css/main2.css") %>" rel="stylesheet" type="text/css" media="all" /> <link href="<%= Server.MapPath("~/css/dropdown.css") %>" media="screen" rel="stylesheet" type="text/css" /> <link href="<%= Server.MapPath("~/css/default.advanced.css") %>" media="screen" rel="stylesheet" type="text/css" /> <link href="<%= Server.MapPath("~/css/vlightbox.css") %>" rel="stylesheet" type="text/css" /> <link href="<%= Server.MapPath("~/css/visuallightbox.css") %>" rel="stylesheet" type="text/css" media="screen" /> <link href="<%= Server.MapPath("~/boxes.css") %>"rel="stylesheet" type="text/css" media="screen" /> <script src="<%= Server.MapPath("~/engine/js/jquery.min.js") %>" ype="text/javascript"></script> <script src="<%= Server.MapPath("~/js/cufon-yui.js") %>" type="text/javascript"></script> <script src="<%= Server.MapPath("~/js/AFB_400.font.js") %>" type="text/javascript"></script> <style type="text/css"> #vlightbox a#vlb { display:none } </style> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js" ></script> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.5.3/jquery-ui.min.js" ></script> <script type="text/javascript"> Cufon.replace('h2');

  • Java Memory Model: reordering and concurrent locks

    - by Steffen Heil
    Hi The java meomry model mandates that synchronize blocks that synchronize on the same monitor enforce a before-after-realtion on the variables modified within those blocks. Example: // in thread A synchronized( lock ) { x = true; } // in thread B synchronized( lock ) { System.out.println( x ); } In this case it is garanteed that thread B will see x==true as long as thread A already passed that synchronized-block. Now I am in the process to rewrite lots of code to use the more flexible (and said to be faster) locks in java.util.concurrent, especially the ReentrantReadWriteLock. So the example looks like this: // in thread A synchronized( lock ) { lock.writeLock().lock(); x = true; lock.writeLock().unlock(); } // in thread B synchronized( lock ) { lock.readLock().lock(); System.out.println( x ); lock.readLock().unlock(); } However, I have not seen any hints within the memory model specification that such locks also imply the nessessary ordering. Looking into the implementation it seems to rely on the access to volatile variables inside AbstractQueuedSynchronizer (for the sun implementation at least). However this is not part of any specification and moreover access to non-volatile variables is not really condsidered covered by the memory barrier given by these variables, is it? So, here are my questions: Is it safe to assume the same ordering as with the "old" synchronized blocks? Is this documented somewhere? Is accessing any volatile variable a memory barrier for any other variable? Regards, Steffen

  • WCF RIA Silverlight deployment issues

    - by Handleman
    It seems the world is awash with people having problems deploying RIA WCF services, and now I'm one too. I've already tried a bunch of things, but to no avail. I need WCF RIA to support a Silverlight 3 application I've built. The short story is, using the new WCF RIA services (Nov 09?) I open VS 2008, create new project (silverlight application), enabling ".NET RIA services". Add new item to web project - Linq2SQL dbml file (from SQL 2005 DB prepared earlier) and compile. I add a new item to the web project - domain service (link the tables I need) and compiled. Using the domain context I "Load" data with a standard RIA get query in the MainPage and add a TextBlock to display returned data. Build & run (cassini) - success. Using VS to publish to IIS on local PC - success. Using VS to publish to test server (IIS6) - browse to location and the Silverlight app loads but Fiddler tells me I've got a 404 on all the the WCF .svc requests. Use Fiddler to "launch IE" on the service request and it's true - 404. I have already run aspnet_regiis, ServiceModelReg and added mime types for .xap, .xaml, .xbap and .svc. I have included the System.Web.Ria and System.Web.DomainServices DLL with copy local true. I need help with either a) a solution b) an approach to find a solution

  • Use of SAX parser in Android - OutOfMemory Issue

    - by Sephy
    Hi everybody, I have been using a SAX parser for a while now to get data from various XML, but today i'm banging my head on a new problem with a hudge XML (compared to the previous ones . here around 12k lines) with a lot of repetitive items in it. Most of the time, the items are part of a block : <content> <item lbl="blabla"> <item lbl="blabla"/> <item lbl="blabla"/> </item> <item lbl="blabla"> <item lbl="blabla"/> <item lbl="blabla"/> <item lbl="blabla"/> <item lbl="blabla"/> <item lbl="blabla"/> <item lbl="blabla"/> </item> </content> The blabla part is of course changing...But, I would like to keep the structure of items (they are titles and subtitles). And for that, I append each blabla with a starting and ending tag blabla, where x is the position in the tree of items (1, 2, 3 or 4). The slightly problematic part is that with that, I'm creating thousands of useless objects and the garbage collector doesn't have time to clean after the parser, and the inevitable OutOfMemory comes in my face... I have no idea of how to deal with it; The best technique would be if I could take the whole content of , but i'm not sure that this is possible with a SAX parser. Any help is welcome and any solution deeply thanked...

  • Alternatives to Java for Android development?

    - by paul.meier
    Hey all, I've started developing Android apps a couple of months ago, and have a few under my belt. While I can tolerate Java enough to keep developing, I was wondering what success the community has had getting other languages to run. I've done some investigation as to how other JVM languages work, and it appears Dalvik messes them up pretty hard. Clojure seems unable to run, Scala seems to be one of the most successful. JRuby has also had some luck, but they caution against anything major. I've also checked out Scheme via Moby and Kawa, both of which seem to have some promise. What luck have any of you had? Languages I'm missing, misrepresenting? Any non-"Hello World" apps you've written in non-Java? Any snags in trying to get another language to run (e.g. "as long as you don't use continuations, you're fine in X Scheme"). Any particular snags in developing apps non-Java, once you get them to run? Thanks, hope you well ^_^

  • Sub Menu Rollover Pop up Not Showing

    - by Stradigos
    Hello everyone, hopefully this will be an easy answer for some of you CSS veterans out there. I'm developing a site for a client. For readability, I'll just give you a link to the website and the css page in question. HTML CSS I'm trying to make a sub menu pop up to the right of the main menu when you scroll over "Star Quartz Grout." My current CSS obviously isn't correct though, and I could use some guidance. ul#subNav {display: none; width: 134px; } li:hover ul#subNav, li.over ul#subNav {display: inline-block; position: absolute; top: 0px; left: 134px; } My guess is that it's working but it's hidden behind the rest of the page. I could be wrong though. It's kind of hard to confirm, even with Chrome's "Inspect Element" (very nice thing btw). It's probably some dumb mistake. Anyway, thanks in advance. I'm a bit of a CSS novice.
