  • Impact of Changing IP Address of Outgoing IP Packets From My Network

    - by iamrohitbanga
    If I modify the source ip address of all outgoing ip packets from my network to an ip address belonging to someone else (while ensuring that the checksum is correct) then what will happen. Assume that I have a public IP address connected by a point-to-point link to an ISP. Will the ISP check that the IP address in my IP packets is correct or will it just forward the packets. I believe that ISP should just forward the packets. what mechanisms are present in the Internet that prevent this from happening?

  • chat application: pubsubhubbub vs xmpp

    - by sofia
    I'm unsure on the best stack to build a chat application. Currently I'm thinking of two main options: facebook tornado cons: does not use the main chat protocol xmpp but pubsubhubbub pros: i really like its simplicity for development (webserver + webframework); pubsubhubbub also seems simpler as a protocol than xmpp; and i know python xmpp + bosch, punjab, ejabberd cons: don't know erlang; overall seems a bit harder to develop pros: uses xmpp protocol The chat app will need to have the following: Private messages Public rooms Private rooms Chat history for rooms (not forever, just the last n messages) html embedding url to chat room Both options seem scalable so that's not really my worry (we're thinking of running the app in amazon's ec2 as well). I know there's a project that builds a xmpp server using tornado but it's not ready for production use and our deadline isn't that big. Basically my main worry is ease of development vs somehow regretting later using pubsubhubbub to develop a chat app but I read somewhere that PubSubHubbub might eventually replace XMPP as REST replaced SOAP - so what do you think?

  • Avoiding .NET versioning hell

    - by moogs
    So sometimes (oftentimes!) you want to target a specific .NET version (say 3.0), but then due to some .NET service packs you get into problems like: Dispatcher.BeginInvoke(Delegate, Object[]) <-- this was added in 3.0 SP2 (3.0.30618 ) System.Threading.WaitHandle.WaitOne(Int32) <-- this was added in 3.5 SP1, 3.0 SP2, 2.0 SP2 Now, these are detected by the JIT compiler, so building against .NET 3.0 in Visual Studio won't guarante it will run on .NET 3.0 only systems. Short of confirming each and every function you use, or limiting your development environment to .NET 3.0 (which sucks since you have to develop for other projects too) what's the best way to avoid against using extensions? Thanks!

  • Problem with asp.net mvc route not firing when in <script> tag

    - by Chev
    I cannot get the following route to fire when a url is requested from a script tag. I have the following route: // maps to "/cache/cachecontent/JavaScriptInclude/1/javascript" routes.MapRoute( null, "cache/{action}/{key}/{version}/{type}", new { controller = "Cache", action = "CacheContent", key = "", version = "", type = "" } ); I have a javascript script tag like: <script type="text/javascript" src="/cache/cachecontent/JavaScriptInclude/1/javascript" /> Yet the route is not firing and the controller is not instantiated. If i drop the url into the address bar of the browser all is fine, but is not triggered from the javascript tag? Any ideas?

  • Regular expressions in URL Rewrite Module for IIS7

    - by TN
    I have following rewrite rule to append .aspx extension if url has no extension. <rule name="SimpleRewrite" stopProcessing="true"> <match url="^(.*(?&lt;=/)([^/.]*))$" /> <action type="Rewrite" url="{R:1}.aspx" /> </rule> However the rule is not working: Error HTTP 500.52 - URL Rewrite Module Error. The expression "^(.*(?<=/)([^/.]*))$" has an invalid syntax. However, this regular expression works in .NET. What regular expressions are supported by IIS Url Rewrite Module? How to make positive lookbehind assertion?

  • Pros and cons of ways of storing an unsigned int without an unsigned int data type

    - by fields
    I have values that are 64-bit unsigned ints, and I need to store them in mongodb, which has no unsigned int type. I see three main possibilities for storing them in other field types, and converting on going in and out: Using a signed int is probably easiest and most space efficient, but has the disadvantage that they're not human readable and if someone forgets to do the conversion, some of them will work, which may obscure errors. Raw binary is probably most difficult for inexperienced programmers to deal with, and also suffers from non-human-readability. A string representation is the least space efficient (~40 bytes in unicode vs 8 bytes per field), but then at least all of the possible values will map properly, and for querying only a conversion to string is required instead of a more complicated conversion. I need these values to be available from different platforms, so a single driver-specific solution isn't an option. Any major pros and cons I've missed? Which one would you use?

    Hi guys, On the official Selenium blog (http://seleniumhq.wordpress.com/) it mentions that Maven is no longer used to build the Selenium project. Can anyone provide me some guidance on the new preferred method for building the selenium project? Everything I've found online is really out of date, referencing the old SVN repos and Maven.

  • Do any parsers exist for the Oracle DML table_reference?

    - by JavaRocky
    I wish to find out what tables references are used in a DML. I prefer to use an oracle package as it can be self contained in the database. But other suggestions welcome. Open source very welcome. Here is the link to the syntax diagram of the table_reference definition: http://download.oracle.com/docs/cd/B19306_01/server.102/b14200/statements_10002.htm#i2126863 Do any parsers exist?

Shoutouts: Check out the new themes, and Tim Heuer's poetry skills: SNEAK PEEK: New Silverlight application themes I learned to program Windows 3.1 from reading Charles Petzold's book, and here we are again: Free ebook: Programming Windows Phone 7 Series (DRAFT Preview) Here's a blog you're going to want to watch, and first up on the blog tonight is links to the complete set of MIX10 phone sessions: The Windows Phone Developer Blog First let me get a couple of things out of my system... "Holy Crap it's March 17th already" and "Holy Crap, we're all Windows Phone Developers!" I'm sure both of those were old news to anyone that's not been in a coma since Monday, but I've been a tad busy here at #MIX10. I'm not complainin' ... I'm just sayin' From SilverlightCream.com: Getting Started with Silverlight and Windows Phone 7 Development With any new Silverlight technology we have to begin with Tim Heuer... and this is Tim's announcement of Silverlight on the Windows Phone 7 Series ('cmon, can I call it a "Silverlight Phone"? ... please?) ... hope I didn't type that out loud :) ... so... in case you fell asleep Sunday, and just woke up, Tim let the dogs out on this and we could all talk about it. In all seriousness, bookmark this page... lots of good links. A guide to what has changed in the Silverlight 4 RC Continuing the 'bookmark this page' thought... Tim Heuer also has one up on what the heck is all in the Silverlight 4 RC they released on Monday... check this out... really good stuff in there... and a great post detailing it all. The Silverlight 4 Release Candidate René Schulte has a good post up detailing the new stuff in Silverlight 4 RC, with special attention paid to the webcam/mic and AsyncCaptureImage Let it ring - WriteableBitmapEx for Windows Phone René Schulte has a Windows Phone post up as well, introducing the WriteableBitmapEx library for Windows Phone... how cool is that?? Silverlight for Windows Phone 7 is NOT the same full Silverlight 3 RTM Bart Czernicki dug into the docs to expose some of the differences between Silverlight for the Windows Phone and Silverlight 3. If you've been developing in SL3 and want to also do Phone, check out this post and his resource listings. Trying to sketch a Windows Phone 7 application Mark Monster tried to SketchFlow a Windows Phone app and hit some problems... if anyone has thoughts, contribute on his blog page. Using Reactive Extensions in Silverlight – part 2 – Web Services Pencho Popadiyn has part 2 of his tutorial on Rx, and this one is concentrating on asynchronous service calls. Silverlight 4 Quick Tip: Out-Of-Browser Improvements This post from Alex Golesh is a little weird since he was sitting next to me in a session at MIX10 when he submitted it :) ... good update on what's new in OOB in the RC Turning a round button into a rounded panel I like Phil Middlemiss' other title for this post: "A Scalable Orb Panel-Button-Thingy" ... this is a very cool resizing button that works amazingly similar to the resizable skinned dialogs I did in Win32!... very cool, Phil! Go Get It – The Windows Phone Developer Training Kit Did you know there was a Windows Phone Training Kit with Hands-on Labs? Yochay Kiriaty at the Windows Phone Developer Blog wrote about it... I pulled it down, and it looks really good! Stay in the 'Light!

  • Working with images in WCF

    - by hgulyan
    Hi, I have a desktop application that needs to upload/download images to/from service computer over TCP Protocol. At first, I stored images in file system, but I need to in MS SQL DB to compare which solution is better. Number of images is over half a million. I don't know yet will there be any limitation on size of a photo. If you have done smth like that, please, write what your opinion upon this question. Which one is faster, more safe? Which of them works better with this number of photos? If I'll store on DB, do I need to store images apart from all other tables which I use for my application and which type works better - image or varbinary on DB?..and so on. Thank you.

  • Vertical scrolling in silverlight

    - by Mrt
    I have a silverlight application that is set to use 100% browser height. As I dynamically add controls to a canvas (which can be dragged around), I would like the expand the canvas vertically. Ideally show the browser scrollbar so the user can move up or down, if that can't be done, use the scrollbar control. I would also need to handle the user changing the size of the browser. Any suggestions on how to do this ? Cheers,
