• Multiple URLs on one domain in IIS 6 [closed]

  - by TGnat

  Possible Duplicate: How to Host Multiple Domains / Web Sites on one IIS6 Server I'm a developer and only know the basics of IIS administration. I want to give each of my clients a personalized URL to access my web site. I have mySite.com and I would like to allow client A to acess the site via A.mySite.com and client B to use B.mySite.com. These would all point the the mySite.com domain with the same ip address. Can this be done in IIS? Do I have to register new domains for each client? Are there other ways to accomplish the same thing?

• WCF without NET 3.0

  - by Murat

  Hello there, Does anyone tell me if it's possible to use WCF without .NET 3.0? Our company develops a 3-tier client-server end-user solution based on .Remoting. One of the limitation of our project is using .NET 2.0. Unfortunately .NET 3.0 framework is too large to be included in our installation package and I don't know if MS license allows this. But WCF might helps us to drastically reduce our efforts in some tasks. Does anyone have a chance to use WCF from Mono? Thanks in advance -- Murat

• Windows 2003 and 2008 AD integrated DNS zones

  - by floyd

  We have a Windows 2003 server DC1 which is our primary DC holding all FSMO roles. It also is a DNS server for our domain domain.local which is an active directory integrated zone. We also have a Windows 2008 DC name DC2 All servers have the correct DNS entries etc. However on all dns servers there are event id 4515 indicating there are duplicate zones in separate directory partitions and only one will be used until the other is removed. And I see these, there is a zone for domain.local under the default naming partition CN=System, CN=MicrosoftDNS, DC=domain.local. As well as the DomainDNSZones partition DC=DomainDNSZones, DC=DOMAIN, DC=local, CN=MicrosoftDNS It seems that the partition in the Default Naming partition is the one which is being used currently. Which one should be in use? How do I make the EventID 4515's go away? EventID 4515: http://support.microsoft.com/kb/867464 Thanks

• Approaches for memcached sessions

  - by Industrial

  Hi everybody, I was thinking about using memcached to store sessions instead of mySQL, which seemed like a good idea, at first. When it comes to the failover part of utilizing memcached servers, It's a bit worrying that my sessions will stop working if the memcached would go offline. It will certainly affect my users. There's a few techniques that we already utilize to reduce failover, including having a pool of servers available to compensate in the event of downtime, utilizing sharding/consistent hashing across the server pool and so on. We would also do some sort of graceful degradation that tells the users that something have gone wrong and they are welcome to login again, in the event of them being kicked out due to memcached server failover. So how does people generally deal with these issues when storing sessions on memcached servers?

• Stripping variable names from VB.Net assemblies

  - by CFP

  Hello every one :) I'm trying to reduce as much as I can my VB.Net assembly side, and I just figured out that all variable names were kept unchanged in the actual assembly. Since I tend to use pretty long var names, it adds up and, by running dotfuscator on my assembly, I could shrink it by as much as 10%. Thus I wonder: is there any way to tell Visual Studio to use shorter var names in the generated assembly? Are there any downsides to using dotfuscator (I'd rated avoid it though, since it'd need to be called after every compilation, therefore forcing me to update my build scripts...)? Thanks a lot, CFP.

  Possible Duplicate: Which wiki satisfies ACL ADI and API ? Hi , is there any wiki that supports ACL , ADI and API ? and my requirement is we need a wiki that does three things 1. Uses ACL (Access Control lists - who can access what pages) 2. Needs AD (active directory integration) 3. Is scriptable via an API (meaning I can create a wiki page through an API in a program instead of logging in and manually typing in the page.) Ur help is appreciated Thanks in Advance Goutham

• Eclipse refresh taking too long

  - by Nash0

  I am doing TDD on a large Java project in eclipse and am finding it frustrating because every time I run a test I have to wait 30 seconds+ for eclipse to compile and refresh. I estimate that 80%+ of that time is spent refreshing. Is there a way I can drastically reduce the amount of refreshing it is doing? I have looked at server other similar questions but I could not see anything that helps. One way I reduced the compile refresh time was to split the unit tests and code into separate projects. There are 4,700 classes in the src project and 300 in the tests. I am running eclipse 3.5.1 on Java 1.6.0_17-b04 (eclipse.vm). My computer is running windows xp with 3.1 gigs of usable ram. The only plugin I have installed is subclipse.

• dilemma about mysql. using condition to limit load on a dbf

  - by ondrobaco

  hi, I have a table of about 800 000 records. Its basically a log which I query often. I gave condition to query only queries that were entered last month in attempt to reduce the load on a database. My thinking is a) if the database goes only through the first month and then returns entries, its good. b) if the database goes through the whole database + checking the condition against every single record, it's actually worse than no condition. What is your opinion? How would you go about reducing load on a dbf?

• best data+partition recovery software

  - by Pennf0lio

  I accidentally formatted my Drive D that contained all my Backups and Documents. I separated my files to my Drive D hoping I will not harm my files. Since I use Acronis Recovery to Install a new OS with some pre-installed application to my HDD I didn't realize I also formated/erase my Drive D. Now my drive D is unpartitioned. I am really in really in deep trouble and would need some urgent help, Please recommend a Software that at least can restore my Old Drive that contained my files. I'm assuming most of you think this is a duplicate of some old questions here, But I'm not looking for data recovery, I need to recover the whole partition with the files. I used to use "Recuva" but It only recovers files not the whole folders with the files in it. Please advice. Thank You!

• How to convert an existing callback interface to use boost signals & slots

  - by the_mandrill

  I've currently got a class that can notify a number of other objects via callbacks: class Callback { virtual NodulesChanged() =0; virtual TurkiesTwisted() =0; }; class Notifier { std::vector<Callback*> m_Callbacks; void AddCallback(Callback* cb) {m_Callbacks.push(cb); } ... void ChangeNodules() { for (iterator it=m_Callbacks.begin(); it!=m_Callbacks.end(); it++) { (*it)->NodulesChanged(); } } }; I'm considering changing this to use boost's signals and slots as it would be beneficial to reduce the likelihood of dangling pointers when the callee gets deleted, among other things. However, as it stands boost's signals seems more oriented towards dealing with function objects. What would be the best way of adapting my code to still use the callback interface but use signals and slots to deal with the connection and notification aspects?

• Looking for a free or open-source burner emulator [closed]

  - by Jared Harley

  Possible Duplicate: Virtual CDR driver I am looking for a free or open-source virtual CD/DVD emulator to run in a Windows environment. What I want is similar to what SlySoft's Virtual Clone Drive or Daemon Tools provides, but the emulated drive needs to be a burner of some type. The burner should be able to save disc images (.iso, .ccd, etc) to my harddrive - basically, the same as if I burned the files to a CD-R, and then ripped them back to a disc image. I have already looked around some and come across 2 - DVD neXt COPY iTurns and NoteBurner M4P. Both of these programs create a virtual CD-RW drive, but they are integrated into their product (for burning from iTunes to create mp3 files) and cannot create disc images. I am currently writing a piece of software that will have the capability to burn disc images onto CDs/DVDs, and I don't want to end up with a 100 coasters while I'm testing my software. Anyone have any ideas? Related ServerFault queston: Create netbook recovery image without DVD burner (virtual burner?)

• Version control and branching when using Oracle

  - by Ed Woodcock

  Hi folks: At work we're using Oracle and C#/ASP.net to handle a customer's website, this site is very large-scale so the database is very large. We use Perforce for our version control, and tack create or replace scripts to FogBugz cases whenever a database change, which has been fine until now, as we are now at a point where five developers are working on five expansions for the system, each on a seperate Perforce branch. Unfortunately, we cannot get duplicate databases, due to the database size, so everyone is still working from the same one. This is obviously a cause of problems: only ten minutes ago we had a bit of an issue where a stored procedure change for a branch propagated over to the Pre-Production server and caused a large number of crashes for the testers. Ideally, we would like a way to track these changes without having to manually keep track of them through FogBugz. My question is: how do you lot handle this situation? I'm sure there must be a good way by now to handle versioning, or at least tracking changes, in an Oracle database.

• size of view not changing after frame change

  - by MikeNelson

  I have managed to do pretty complex things on iPhone but I am always stuck with views, frames, bounds, and simple stuff that defies any logic and don't work as expected. I have a self.view in my code and it has a lot of subviews on it. At some point of the code, I need to reduce the frame vertically to a specific size and later put it back as before. Then I have this code: [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:1.5]; // frame is changing to a newHeight (other parameters are the same as before) self.view.frame = CGRectMake (0, 0, originalWidth, newHeight); [UIView commitAnimations]; The result is simply, nothing. The view continues as before. The same size, the same position. No change. Why this kind of thing happens? how to solve that?

• Simple reduction (NP completeness)

  - by Allen

  hey guys I'm looking for a means to prove that the bicriteria shortest path problem is np complete. That is, given a graph with lengths and weights, I need to know if a there exists a path in the graph from s to t with total length <= L and weight <= W. I know that i must take an NP complete problem and reduce it to this one. We have at our disposal the following problems to choose from: 3-SAT, independent set, vertex cover, hamiltonian cycle, and 3-dimensional matching. Any ideas on which may be viable? thanks

• Is Stopwatch really broken?

  - by Jakub Šturc

  At MSDN page for Stopwatch class I discovered link to interesting article which makes following statement about Stopwatch: However there are some serious issues: This can be unreliable on a PC with multiple processors. Due to a bug in the BIOS, Start() and Stop() must be executed on the same processor to get a correct result. This is unreliable on processors that do not have a constant clock speed (most processors can reduce the clock speed to conserve energy). This is explained in detail here. I am little confused. I've seen tons of examples of using Stopwatch and nobody mention this drawbacks. How serious is this? Should I avoid using Stopwatch?

• Bitmapdata heavy usage - memory disaster (spark/FB4)

  - by keyle

  I've got a flex component which works pretty well but unfortunately turns into a disaster once used in a datagroup item renderer of about 40-50 items. Essentially it uses bitmapdata to take screenshot of a fully-rendered webpage in mx:HTML (this version of webkit rocks btw, miles better than flex 3). The code is pretty self-explanatory I think. http://noben.org/show/PageGrabber.mxml I've optimized it all I could, browsed, search for answers and already trimmed it down a lot, I'm desparate to reduce the memory usage (about 600mb after 100 draw) The Garbage collector has little effect. Thanks! Nic

• Why isn't Hadoop implemented using MPI?

  - by artif

  Correct me if I'm wrong, but my understanding is that Hadoop does not use MPI for communication between different nodes. What are the technical reasons for this? I could hazard a few guesses, but I do not know enough of how MPI is implemented "under the hood" to know whether or not I'm right. Come to think of it, I'm not entirely familiar with Hadoop's internals either. I understand the framework at a conceptual level (map/combine/shuffle/reduce and how that works at a high level) but I don't know the nitty gritty implementation details. I've always assumed Hadoop was transmitting serialized data structures (perhaps GPBs) over a TCP connection, eg during the shuffle phase. Let me know if that's not true.

• Accumulate 2D Array by Index

  - by Tegan Snyder

  I have an array that looks like this: Array ( [0] => Array ( [amount] => 60.00 [store_id] => 1 ) [1] => Array ( [amount] => 40.00 [store_id] => 1 ) [2] => Array ( [amount] => 10.00 [store_id] => 2 ) ) What would be a good method to reduce the array to a similar array that totals the 'amount' related to a store_id. For Instance I'd like to get this: Array ( [0] => Array ( [amount] => 100.00 [store_id] => 1 ) [2] => Array ( [amount] => 10.00 [store_id] => 2 ) )

• Most efficient way to solve system of equations involving the digamma function?

  - by Neil G

  What is the most efficient way to solve system of equations involving the digamma function? I have a vector v and I want to solve for a vector w such that for all i: digamma(sum(w)) - digamma(w_i) = v_i and w_i 0 I found the gsl function gsl_sf_psi, which is the digamma function. Is there an identity I can use to reduce the equations? Is my best bet to use a solver? I am using C++0x; which solver is easiest to use and fast?

• Remove iTunes on Mac OS X permanently: no Software Update

  - by ShreevatsaR

  Somewhat predictably, removing iTunes on Mac OS X is a long arduous process, described at http://support.apple.com/kb/ht1224 — which I have followed. As far as I can tell, I have purged every trace of the accursed iTunes from my system. Yet Software Update repeatedly prompts me with updates for iTunes, which I don't want anything to do with, despite my saying "Not now" each time. How can I convince Software Update to leave me alone, and never bother me with mention of iTunes again? I'm on Mac OS X 10.6.4 Build 10F569, and the update being offerred is iTunes 9.2.1. (Note: Not a duplicate of OS X: why Software Update suggests to update removed application?, whose accepted answer is simply to follow the instructions I mentioned above.)

• Using PIG with Hadoop, how do I regex match parts of text with an unknown number of groups?

  - by lmonson

  I'm using Amazon's elastic map reduce. I have log files that look something like this random text foo="1" more random text foo="2" more text noise foo="1" blah blah blah foo="1" blah blah foo="3" blah blah foo="4" ... How can I write a pig expression to pick out all the numbers in the 'foo' expressions? I prefer tuples that look something like this: (1,2) (1) (1,3,4) I've tried the following: TUPLES = foreach LINES generate FLATTEN(EXTRACT(line,'foo="([0-9]+)"')); But this yields only the first match in each line: (1) (1) (1)

• Improving the speed of php

  - by cast01

  I'm currently working on a website in PHP, and I'm wondering what the best practices/methods are to reduce the time requests take. I've build the site in a modular way, so a page would consist of a number of modules, and each of these would need to request information. For example, I have a cart module, that (if a cart is set) will fetch the cart with the id (stored in a session variable) from the database and return its contents. I have another module that lists categories and this needs to fetch the categories from the database. My system is built with models, and each model might also make a request, for example a category model will make a request to get products in that category.

• Scheduled Jobs during hours of autumn time change

  - by NealWalters

  I'm wondering how other people deal with this scenario. What if you have a job scheduled to run at 1:30 am. In the autumn, when time changes, the hour of 1:00:00 to 1:59:59 repeats itself and so that job would run twice. Could be Windows Task Scheduler, SQL Agent or any other scheduling tool. Most of these tools seem to be based on machine time, not UTC time. If I told it to run the job at UTC time each night, then I wouldn't have the duplicate hour issue.

• Problems with merge replication

  - by jess

  Hi, We are developing a multi-user desktop application with users located in different countries. The platform is - .net 3.5, SQL Server 2008, WinForms. Now, my client has used the help of a DBA who has implemented merge replication. To facilitate replication, we made all our primary keys as GUID. Now, we are facing these issues with replication - subscribers expiration sometimes stops replication and we have found no clean way to re-add every change to db schema requires to poll the whole data all over again! This seems to be strange, what could be the problem here? Also, sometimes we have duplicate keys, and that too stops replication I am sure these issues can be resolved. Maybe, we have not gone the right way to implement. Can you suggest how to go about implementing. Or, is the above information enough to diagnose the problem?
