• cross-domain javascript

  - by rutherford

  I am producing a javascript-based widget. Nothing complex just a few document.writes... When I place it inline in the page it renders fine in all browsers. When I place it externally and load it via it fails to render in Firefox and IE but not Chrome. Anyone know why and a possible workaround?

• Using C++11 for cross-platform Game Engine Development

  - by Samaursa

  Note: This is not a 'give your opinion' question about C++03 and C++11. Our game engine, written in C++03, is designed to be compiled on Windows, OSX and iOS. Linux support is planned for the (very) near future. Our experience is limited when it comes to consoles, which is why I am asking this question. Currently, we are debating whether switching to C++11 and using non-compatible features of the C++11 standard could pose a problem in the near future when we need to port our engine to any of the current gen consoles (perhaps the compilers supported by some console(s) do not support C++11 yet? We don't know...). So, game developers who have experience across multiple platforms and consoles, do you think we should stick to C++03 until the new generation of consoles arrive and most everybody has switched to C++11 standard (have they already?). Or are most consoles using/support compilers (VC++, GCC or variants?) that are already supporting C++11 features?

• Webinar on Cross Platform Development with MonoTouch for the iPhone and Mono for Android on Wednesday

  - by Wallym

  The iPhone and Android are dominant in the marketplace. The two platforms currently have 85% of the smartphone marketplace and are continuing to grow that marketshare. Developers are being tasked with targeting these two platforms. In this session, we’ll take a high level look at how we can use c# and .NET knowledge to share code between iOS and and Android. We’ll look at linked files, using the Xamarin Mobile API, the challenges of running across platforms and frameworks, as well as other features of Visual Studio, Monotouch, MonoDevelop, and Mono for Android that allows us to write as much code that can run on both platforms.Here is the registration link: https://www302.livemeeting.com/lrs/8001676474/Registration.aspx?pageName=2w197495hzh0t56g

• Which API for cross platform mobile audio?

  - by deft_code

  This question focuses on the API's available on phones. I'd been planning to use OpenAL in my game for maximum portability. It runs great on Linux so I can quickly develop the Game and leverage it's superior debugging tools. However I've recently heard that Android doesn't support OpenAL well. Instead they've gone with a OpenSL ES library. What I'm looking for is a free Audio library that I can use with minimal custom code on iPhone, Android, and my Linux desktop. Does such an API exists? Some extra details: The game is written in C++ with custom minimal front ends. ObjC for iPhone, Java for Android, and SFML for Desktops. I'm using OpenGL ES for portability as iPhone doesn't support the more advanced OpenGL APIs.

• Are Colocation Cross Connects Worth While

  - by SvrGuy

  We currently operate three clusters of collocated machines in different data centers. Recently, I became aware that our newest data center will offer to cross connect us to a bandwidth provider free of charge. In the past, I never really investigated a cross connect for bandwidth because I figured that the rates would be similar to what we are paying the colo now and that it would reduce our resiliency (because we would only be using one or two carriers for IP, where as the colo uses, say 8 different providers). Then I saw an ad for hurricane electric internet services (http://he.net/cgi-bin/ip_transit_quote) that gave a price for IP transit at $1/Mbs, which is much better than the $30/Mb we pay for the blended bandwidth. What are people out there typically paying for bandwith via cross connect and how hard is to setup? Is my understanding that what you do is open agreemetns with two or three ISPs, cross connect to them and then configure your top of rack router on their network. Can you really get IP transit down to a couple of dollars per megabit per month just by doing the routing yourself? Or, is my understanding of cross connection fundamentally wrong?

• Is there a trend for cross-platform GUI toolkits?

  - by Anto

  What is the trend like for the usage of cross-platform GUI frameworks right now? Are more people starting to use cross-platform frameworks (such as GTK+, Qt and wxWidgets) or are there more who use more platform-tied frameworks (e.g. Cocoa or WPF)? Is it more or less stagnant? Is it like a rollercoaster? What do you think the trend will be like, say, 5 years from now? The OS landscape is shifting with less people using Windows (personal observation). This should increase the demand for cross-platform toolkits, shouldn't it? Edit: Also, which (cross-platform) toolkits are growing the most, if so?

• Cross platform mobile development VS Native Mobile Development: Present And Future.

  - by MobileDev123

  I just completed one year in Smart phone development, working on BlackBerry and Android and also developed one application exclusively targeted to nokia feature phones. And just a month ago I come to know about Titanium Appcelerator tool that enables cross platform development, but there are some developers who complain about it's sub-par functionalities. Even a little bit experience of mine says that developing in native environment rather than these cross platform tools will give you more advantages by giving a developer a chance to add more features with better performance. Do you have same experience? Or you find such cross development tools really useful regarding to advance functionality and performance? As porting (or co developing) same application to different mobile platform is common thing nowadays, what do you think will these cross platform tools evolve and force developers to get a hands on approach on them or majority will stick to the native development environment?

• Glitch-free cross-fades in HTML5

  - by Alexander Gladysh

  In my HTML5 canvas game, I need to cross-fade two sprites which have some glow around them. (Glow is backed into sprites.) Initially, the first sprite is visible. During the cross-fade the first sprite should vanish, and be replaced with the second one. How exactly the cross-fade is done — does not matter, as long as it is smooth and there are no visual glitches. I've tried two techniques: During the cross-fade I simultaneously interpolate alpha of the first sprite from 1.0 to 0.0, and alpha of the second sprite — from 0.0 to 1.0. With this technique I can see background in the middle of the cross-fade. That's because both sprites are semi-transparent most of the time. During the cross-fade I first interpolate alpha of the second sprite from 0.0 to 1.0 (first sprite alpha is at 1.0), and then interpolate alpha of the first sprite from 1.0 to 0.0. With this technique background is not seen, but the glow around sprites flashes during the cross-fide — when both sprites are near the full visibility. In non-HTML5 game I'd use shaders to do cross-fade separately in RGB and alpha channels. Is there a trick to do the cross-fade I need in HTML5 without visual glitches?

• BizTalk Cross Reference Data Management Strategy

  - by charlie.mott

  Article Source: http://geekswithblogs.net/charliemott This article describes an approach to the management of cross reference data for BizTalk.  Some articles about the BizTalk Cross Referencing features can be found here: http://home.comcast.net/~sdwoodgate/xrefseed.zip http://geekswithblogs.net/michaelstephenson/archive/2006/12/24/101995.aspx http://geekswithblogs.net/charliemott/archive/2009/04/20/value-vs.id-cross-referencing-in-biztalk.aspx Options Current options to managing this data include: Maintaining xml files in the format that can be used by the out-of-the-box BTSXRefImport.exe utility. Use of user interfaces that have been developed to manage this data: BizTalk Cross Referencing Tool XRef XML Creation Tool However, there are the following issues with the above options: The 'BizTalk Cross Referencing Tool' requires a separate database to manage.  The 'XRef XML Creation' tool has no means of persisting the data settings. The 'BizTalk Cross Referencing tool' generates integers in the common id field. I prefer to use a string (e.g. acme.country.uk). This is more readable. (see naming conventions below). Both UI tools continue to use BTSXRefImport.exe.  This utility replaces all xref data. This can be a problem in continuous integration environments that support multiple clients or BizTalk target instances.  If you upload the data for one client it would destroy the data for another client.  Yet in TFS where builds run concurrently, this would break unit tests. Alternative Approach In response to these issues, I instead use simple SQL scripts to directly populate the BizTalkMgmtDb xref tables combined with a data namepacing strategy to isolate client data. Naming Conventions All data keys use namespace prefixing.  The pattern will be <companyName>.<data Type>.  The naming conventions will be to use lower casing for all items.  The data must follow this pattern to isolate it from other company cross-reference data.  The table below shows some sample data. (Note: this data uses the 'ID' cross-reference tables.  the same principles apply for the 'value' cross-referencing tables). Table.Field Description Sample Data xref_AppType.appType Application Types acme.erp acme.portal acme.assetmanagement xref_AppInstance.appInstance Application Instances (each will have a corresponding application type). acme.dynamics.ax acme.dynamics.crm acme.sharepoint acme.maximo xref_IDXRef.idXRef Holds the cross reference data types. acme.taxcode acme.country xref_IDXRefData.CommonID Holds each cross reference type value used by the canonical schemas. acme.vatcode.exmpt acme.vatcode.std acme.country.usa acme.country.uk xref_IDXRefData.AppID This holds the value for each application instance and each xref type. GBP USD SQL Scripts The data to be stored in the BizTalkMgmtDb xref tables will be managed by SQL scripts stored in a database project in the visual studio solution. File(s) Description Build.cmd A sqlcmd script to deploy data by running the SQL scripts below.  (This can be run as part of the MSBuild process).   acme.purgexref.sql SQL script to clear acme.* data from the xref tables.  As such, this will not impact data for any other company. acme.applicationInstances.sql   SQL script to insert application type and application instance data.   acme.vatcode.sql acme.country.sql etc ...  There will be a separate SQL script to insert each cross-reference data type and application specific values for these types.

• portable cross-platform WebDAV Client

  - by theduke

  I am looking for a portable application that will allow me to do this: Browse a WebDAV share and open a file. Edit the file locally. Save the file, and automatically propagate the change to WebDAV. Is there any CROSS-PLATFORM application out there that will let me do this and exists as a portable? The reason I need this functionality is that I regularily have to access files via WebDAV from public machines where I do not have the neccessary permissions to natively mount a webdav share, or to install the neccessary components.

• Cross-Forest Trust

  - by cdalley

  I am looking at testing a cross-domain trust we can have two domain controllers (with different forests and domain names) setup so we can move everyone onto the new domain. We do NOT run exchange on site and we do not have any links to O365 to AD currently. Onto the problem: I have setup two DCs in a Virtual Machine: They are on the same network 192.168.0.* The Windows 2003 server: Name: OLDSRVR "Clone" of our current Domain Controller IP: 192.168.0.1 Domain: internal.test.com The Windows 2012 server: Name: ADCTEST01 Brand new domain setup from scratch separate to internal.test.com Domain: internal.test2.com IP: 192.168.0.2 OLDSRVR can only see ADCTEST if it has dynamic IP set. If I set a static IP it cannot see it. If I try using the dynamic IP and try to join it gets to the end then complains "??The trust relationship between this workstation and the primary domain failed" Any ideas?

• Loading cross domain XML with Javascript using a hybrid iframe-proxy/xsl/jsonp concept?

  - by Josef

  On our site www.foo.com we want to download and use http://feeds.foo.com/feed.xml with Javascript. We'll obviously use Access-Control but for browsers that don't support it we are considering the following as a fallback: On www.foo.com, we set document.domain, provide a callback function and load the feed into a (hidden) iframe: document.domain = 'foo.com'; function receive_data(data) { // process data }; var proxy = document.createElement('iframe'); proxy.src = 'http://feeds.foo.com/feed.xml'; document.body.appendChild(proxy); On feeds.foo.com, add an XSL to feed.xml and use it to transform the feed into an html document that also sets document.domain and calls the callback function in its parent with the feed data as json: <?xml version="1.0"?> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"> <xsl:template match="ROOT"> <html><body> <script type="text/javascript"> document.domain = 'foo.com'; parent.receive_data([<xsl:apply-templates/>]); </script> </body></html> </xsl:template> <!-- templates that transform data into json objects go here --> </xsl:stylesheet> Is there a better way to load XML from feeds.foo.com and what are the ramifications of this iframe-proxy/xslt/jsonp trick? (..and in what cases will it fail?) Remarks This does not work in Safari & Chrome but since both support Access-Control it's fine. We want little or no change to feeds.foo.com We are aware of (but not interested in) server-side proxy solutions update: wrote about it

• How do I cross-compile my application for Ubuntu 12.04 armhf architecture on a Ubuntu 12.04 i386 host?

  - by Jonathan Cave

  I have a large application I have written. I can successfully compile the application in the following scenarios: in a native compilation for the i386 host running Ubuntu 12.04 natively on a PandaBoard running Ubuntu 12.04 (this takes a long time) using Qemu and a chroot on the host PC for the armhf PandaBoard target (this takes a very long time) I would like to cross-compile the application on the i386 host to run on a target such as the PandaBoard to complete builds in a timely fashion. So far attempts made using the arm-linux-gnueabihf tool chain in the repositories has produced binaries that do not run correctly. At this stage, I have no plans to package the software. What is the recommended way to achieve a successful cross-compile?

• How to explain that writing universally cross-platform C++ code and shipping products for all OSes is not that easy?

  - by sharptooth

  Our company ships a range of desktop products for Windows and lots of Linux users complain on forums that we should have been written versions of our products for Linux years ago and the reason why we don't do that is we're a greedy corporation all our technical specialists are underqualified idiots Our average product is something like 3 million lines of C++ code. My and my colleagues analysis is the following: writing cross-platform C++ code is not that easy preparing a lot of distribution packages and maintaining them for all widespread versions of Linux takes time our estimate is that Linux market is something like 5-15% of all users and those users will likely not want to pay for our effort when this is brought up the response is again that we're greedy underqualified idiots and that when everything is done right all this is easy and painless. How reasonable are our evaluations of the fact that writing cross-platform code and maintaining numerous ditribution packages takes lots of effort? Where can we find some easy yet detailed analysis with real life stories that show beyond the shadow of a doubt what amount of effort exactly it takes?

• C# Thread Pool Cross-Thread Communication

  - by Goober

  The Scenario I have a windows forms application containing a MAINFORM with a listbox on it. The MAINFORM also has a THREAD POOL that creates new threads and fires them off to do lots of different bits of processing. Whilst each of these different worker threads is doing its job, I want to report this progress back to my MAINFORM, however, I can't because it requires Cross-Thread communication. Progress So far all of the tutorials etc. that I have seen relating to this topic involve custom(ish) threading implementations, whereas I literally have a fairly basic(ish) standard THREAD POOL implementation. Since I don't want to really modify any of my code (since the application runs like a beast with no quarms) - I'm after some advice as to how I can go about doing this cross-thread communication. ALTERNATIVELY - How to implement a different "LOGTOSCREEN" method altogether (obviously still bearing in mind the cross-thread communication thing). WARNING: I use this website at work, where we are locked down to IE6 only, and the javascript thus fails, meaning I cannot click accept on any answers during work, and thus my acceptance rate is low. I can't do anything about it I'm afraid, sorry. EDIT: I DO NOT HAVE INSTALL RIGHTS ON MY COMPUTER AT WORK. I do have firefox but the proxy at work fails when using this site on firefox. FURTHER EDIT: I DO NOT WANT TO CHANGE MY THREADING IMPLEMENTATION. AT ALL! - Accept to enable cross-thread communication....why would a backgroundworker help here!?

• What language should I use for making a cross platform library?

  - by Andrei

  I want to build a SyncML parsing library (no UI) which should be able to build up messages based on information provided by the host application, fed in by the library's methods. Also, the library should to be able to do callbacks to methods in the host application. I want to be able to compile this and have it available on as many platforms as possible: Windows, Windows Phone 7 OS, OSX, iOS, Linux, Android, BlackBerry. Basically as many platforms as possible. The priority is to have this available on mobile devices. Questions: What setup should I use? (programming languages, compilers, IDE etc.) How would I compile this library for these different platforms and how would I connect to it? Any other info? e.g. articles that cover the subject of cross-platform development? I haven't done this sort of a cross-platform project before, so any available information to put me in the right direction would be welcomed. Myself, I have a background in C#/.NET and Objective-C.

• MinGW - cross compile tool - latest version?

  - by Petike

  At the MinGW download page you can download the "Cross-Hosted MinGW Build Tool" which is a shell script to build the "MinGW cross-compiler" so that you will be able to compile your programs on "Linux" to the "Windows" target. I have downloaded that script, run it and answered the interactive questions the script has asked me. I had to dowload some files from which one has name "gcc-core". And the "latest" version of the "gcc-core source code" I have found on that page, was "gcc-core-3.4.5-20060117-2-src.tar.gz" - so that "3.4.5" version. But on "Ubuntu Linux" I can download the precompiled "mingw32" package which is of the version "4.2.1". How is it possible that the "Ubuntu package" version of MinGW is newer than the one from the MinGW "homepage"? So which is the latest version of the "MinGW cross compile tool"?

• Cross-platform configuration, options, settings, preferences, defaults

  - by hippietrail

  I'm interested in peoples' views on how best to store preferences and default settings in cross-platform applications. I primarily work in Perl on *nix and Windows but I'm also interested in the bigger picture. In the *nix world "dotfiles" (and directories) are very common with system-wide or application default settings generally residing in one path and user-specific settings in the home directory. Such files and dirs begin with a dot "." and are hidden by default from directory listings. Windows has the registry which also has paths for defaults and per-user overrides. Certain cross-platforms do it their own way, Firefox uses JavaScript preference files. Should a cross-platform app use one system across platforms or say dotfiles on *nix and registry on Windows? Does your favourite programming language have a library or module for accessing them in a standard way? Is there an emerging best practice or does everybody roll their own?

• Best cross-platform solution for network server?

  - by Anonymous

  Hi, im starting a new project and for the first time i want to be cross-platform. But the tricky is my project would involve listen server, cryptos etc., etc. So i was wondering what is the best solution for cross-platform development (OpenSSL, instead of MSCrypto etc.) that would be easy to write with VS2010 (yeah the RC). The language is still not specified (depends on witch we would be easier) but im leaning to Visual C++. In Cross-Platform i mean windows/generic unix compilation.

• Cross domain LDAP

  - by Adam

  For a system we are developing we have 2 domains an internal and an external domain with bi directional trust between them. However the servers are only able to connect to their own DC's. We have an application server on the internal domain which needs to use an LDAP query to gather a list of users from a group on the external domain. How do i go about writing an LDAP query that asks one DC to go ask another DC for a list of users. I tried querying the internal DC with the same LDAP query I would use if it could hit the external DC directly but this does not work. When i use Softerra LDAP Administraor I can view the full hierarchy of the interal domain but despite the trust relationship between domains i am unable to see any of the external doamin. Any suggestions or help would be greatly appreciated

• Cross OS data recover question, USB drive involved.

  - by Moshe

  Here's the story: A MacBook had OS X 10.4 and Windows XP dual booting using rEFIt. Then the Windows partition gets corrupted and it won't boot. Presumably a virus. There were sensitive files there and those were successfully copied to a USB drive and then 10.5 was installed on the hard drive, formatting the drive in the process. The USB drive's contacts cracked and he data is lost from there, unless it can be resoldered. The issues is that there is too much solder there already. So, how can the data in question be recovered? The files were Microsoft Money (not the latest version) files for the Windows version of the program. Right now, only OS X is installed on the MacBook. Is there Mac based program that can recover the Windows data or am I better off trying to resolder the drive? Does anyone know how to best resolder a USB drive more than once, where the first solder is ther, but detached from the silicon? Also, what format (extension) are Microsoft Money files? In need of help!
