• Should ActionResult perform other tasks too

  - by Ori

  In Asp.net MVC one is encouraged to derive custom ActionResults, however should these classes handle other tasks unrelated to views, perhaps a EmailActionResult would render a view then send an email. What is best practice for the class ActionResult, is it only view specific? I want to keep things DRY too. Should the sending of the email be factored into a service class? perhaps using a filter would work. what are your thoughts?

• Speeding up inner joins between a large table and a small table

  - by Zaid

  This may be a silly question, but it may shed some light on how joins work internally. Let's say I have a large table L and a small table S (100K rows vs. 100 rows). Would there be any difference in terms of speed between the following two options?: OPTION 1: OPTION 2: --------- --------- SELECT * SELECT * FROM L INNER JOIN S FROM S INNER JOIN L ON L.id = S.id; ON L.id = S.id; Notice that the only difference is the order in which the tables are joined. I realize performance may vary between different SQL languages. If so, how would MySQL compare to Access?

• Embeded FLEX Control Hosted in JBOSS, How do i use Http Basic Authentication with "embed" or "object

  - by RyanFetz

  So we have three FLEX controls hosted within a JBOSS server instance, and an IIS (MVC) application which has pages that have the object (and embed) tags to render the controls. We are wanting to setup HTTP basic authentication on the jboss server which is hosting other services (Solr, some custom webservices, and tika) and have figured out how to pass the credentials. How can you send those basic http authentication credentials to a flex control in object/embed tags??

• SQL Server 2000 DTS Package Failing with "The number of failing rows exceeds the maximum specified"

  - by Scott McCormick

  I have inherited a SQL Server 2000 DTS package that migrates data from SQL Server to Oracle. This package moves about 20 tables' data to Oracle every night with no transformations, and it is then transformed by a set of SPs and used by a GIS application. Twice this week, during the migration between SQL Server and Oracle, the package has failed with "The number of failing rows exceeds the maximum specified". It has failed on a different table each time, though. Each time it's failed, we've rerun the process the next morning and it has worked. Because the process works the second time it's run, it makes me think the data is being changed by someone or something between the initial failure and our successful second run. I would like to change the DTS package to log the failing rows in a text document so we can compare them later. Can someone help me with that? I can't seem to figure that part out. Scott

• Can two function in a class be accessed simultaneously in AS3?

  - by Roger B

  In a custom queue, there's a push() and a pop() function. The pop() may be called any time on an Event.COMPLETE, so does this mean that code can be running in push() and pop() simultaneously? If so, is there a way to prevent the code from being run in both functions at the same time?

• PHP getopt Operations

  - by Rachel

  This question is regarding getopt function in php. I need to pass two parameter to the php scripts like php script.php -f filename -t filetype Now depending upon the file type which can be u, c or s I need to do proper operation. I am using switch case for the same: Here is the Code I am using: // Get filename of input file when executing through command line. $file = getopt("f:t:"); Switch case should compare the type of the file which I am passing in from the command line (u, c or i) and accordingly match it and do the operation. switch("I am not sure what should go in there and this is wrong,Please advice") { case `Not sure`: $p->ini(); break; case `Not sure`: $p->iniCon(); break; case `Not sure`: $p->iniImp(); break; } Kindly advise on this !!!

• Alternative databases to use when putting IIS Logs into a database using LogParser

  - by Robin Day

  We have run some scripts that use LogParser to dump our IIS logs into a SQL Server database. We can then query this to get simple stats on hits, usage etc. It's also good when linking it to error log databases and performance counter database to compare usage with errors, etc. Having implemented this for just one system and for the last 2-3 weeks we already have a 5GB database with around 10 million records. This is making any queries to this database quite slow and will no doubt cause storage issues if we continue to log as we are. Can anyone suggest any alternative databases that we could use for this data that would be more efficient for such logs? I'd be particularly interested in any experience of Google's BigTable or Amazon's SimbleDB. Are either of these suitable for reporting queries? COUNTs, GROUP BYs, PIVOTs?

• An algorithm Problem

  - by Vignesh

  For coverage, I've a set of run time variables of from my program execution. It happens that I get it from a series of executions(Automated testing). ie. its a vector<vector<var,value>> I've a limited set of variables with expected values and generate combination s, that is I have vector<vector<var,value>(smaller than the execution vector)>. Now I need to compare and tell which of the combination I generated were exactly executed in one of the tests. My algo is O(n^4). Is there any way to bring it down. Something like set intersection. I'm using java, and vectors because of thread safety.

• Audio Detection in Matlab

  - by insane-36

  I am writing a matlab code that would be able to read the audio file and then compare it to the another audio and recognize if those audio are the voice of the same person. In both type of the audio, would have the same word utterance and the audio is about 1 minutes long. I have come to know that the approach of sliding windows using hamming window would work best on this approach but have a very little idea on this. The simple code to read an audio file and then display a portion of 10s is as below : [x,fs, nbits]= wavread('01-AudioTrack 01.wav'); subplot(211) plot(x) title('Entire Wave') smallRange = 1:100000; subplot(212) plot(smallRange,x(smallRange)) How do I make Hamming window each of 10ms in this case and what approaches should I take to deal with this problem ?

• How do I transfer this logic into a LINQ statement?

  - by Geoffrey

  I can't get this bit of logic converted into a Linq statement and it is driving me nuts. I have a list of items that have a category and a createdondate field. I want to group by the category and only return items that have the max date for their category. So for example, the list contains items with categories 1 and 2. The first day (1/1) I post two items to both categories 1 and 2. The second day (1/2) I post three items to category 1. The list should return the second day postings to category 1 and the first day postings to category 2. Right now I have it grouping by the category then running through a foreach loop to compare each item in the group with the max date of the group, if the date is less than the max date it removes the item. There's got to be a way to take the loop out, but I haven't figured it out!

• Are all the system's floating points operations the same?

  - by Jj

  We're making this web app in PHP and when working in the reports we have Excel files to compare our results to make sure our coding is doing the right operations. Now we're running into some differences due floating point arithmetics. We're doing the same divisions and multiplications and running into slightly different numbers, that add up to a notable difference. My question is if Excel is delegating it's floating point arithmetic to the CPU and PHP is also relying in the CPU for it's operations. Or does each application implements its own set of math algorithms?

• Object comparison in JavaScript

  - by spankmaster79

  What is the best way to compare Objects in JavaScript? Example: var user1 = {name : "nerd", org: "dev"}; var user2 = {name : "nerd", org: "dev"}; var eq = user1 == user2; alert(eq); // gives false I know that "Two objects are equal if they refer to the exact same Object", but is there a way to check it another way?? Using this way works for me.....but is it the only possibility? var eq = Object.toJSON(user1) == Object.toJSON(user2); alert(eq); // gives true

• Is there an easy way to make `boost::ptr_vector` more debugger friendly in Visual Studio?

  - by Billy ONeal

  I'm considering using boost::ptr_container as a result of the responses from this question. My biggest problem with the library is that I cannot view the contents of the collection in the debugger, because the MSVC debugger doesn't recognize it, and therefore I cannot see the contents of the containers. (All the data gets stored as void * internally) I've heard MSVC has a feature called "debugger visualizers" which would allow the user to make the debugger smarter about these kinds of things, but I've never written anything like this, and I'm not hugely firmiliar with such things. For example, compare the behavior of boost::shared_ptr with MSVC's own std::tr1::shared_ptr. In the debugger (i.e. in the Watch window), the boost version shows up as a big mess of internal variables used for implementing the shared pointer, but the MSVC version shows up as a plain pointer to the object (and the shared_ptr's innards are hidden). How can I get started either using or implementing such a thing?
