• How do I control script execution time in PHP

  - by mathew

  for example I do have 5 PHP functions on a page which execute when loading. each functions has its own processing time and some of them take more time sometimes to complete the task. hence the total loading time of the said page is slow. my question is how do I control execution time for each script and set time limit for the same. I am aware that there is an in built function in PHP called set_time_limit(); but it gives fatal error if time is beyond the maximum limit...

• SQL Server deadlock issue

  - by George2

  Hello everyone, I am using SQL Server 2008 Enterprise. I am wondering whether dead lock issue is only caused by cross dependencies (e.g. task A has lock on L1 but waits on lock on L2, and at the same time, task B has lock on L2 but waits on lock on L1)? Are there any other reasons and scenarios which will cause deadlock? Are there any other way which will causes dead lock -- e.g. timeout (a S/I/D/U statement do not return for a very long time, and deadlock error will be returned) or can not acquire lock for a long time but not caused by cross-dependencies (e.g. task C needs to get lock on table T, but another task D acquire the lock on table T without releasing the lock, which causes task C not be able to get lock on table T for a long time)? thanks in advance, George

• learning and "singing" Ruby with Sinatra

  - by microspino

  Hello I'm trying to improve my ruby knowledge by reading The Ruby Programming Language book. Reading Coders at work I saw that lot of the interviewees suggest to dive into a project source code to learn best practices to be aware of bad habits and of course to take new inspirations for how to do things. I decided to pick a project as more self contained as I could find. My choice was Sinatra since It's 1000 LOC. Is It a good project to learn? Do you suggest another one more simple (i.e. less LOCs)? I've tried to see rails machinery before but I came out scared from It.

• Wrapping Multiple Elements (jQuery)

  - by Nimbuz

  I've this piece of HTML: div.content div.one content div.two content div.three content I want to add two divs on top and bottom and wrap one div around it so it becomes: div.top div.wrapper div.content div.one content div.two content div.three content div.bottom I'm aware of the several wrap selectors (innerWrap, wrapAll etc..) but I'm not sure how to wrap 2 divs. The following jQuery might work, but is there a better way to write it? $('content').wrap('<div class="wrapper"></div'); $('.wrapper').before('<div class="top"></div>'); $('.wrapper').after('<div class="bottom"></div>');

• how to selfhost wcf without iis

  - by dotnetcoder

  Reading up on WCF we have self hosting option available , one limitation here is we have to manage the host process lifecycle ourselves. What I am exploring here is to run the service without IIS and do a self hosting. Few things come to mind - How will request management work here. In case of IIS it manages the request and give control to dotnet on a particular thread. In absence of IIS do we need to write code ourselves to manage incoming requests ( say on a tcp port ) or WCF provides some classes to manage request and spawn threads to process each thread. I am aware that in case of self hosting this needs to be a windows service. In case of self hosting how can me tap on the number of simultaneous requests on the sever , it can be managed by limiting the thread pool ? or we can configure this via wcf ? Thanks dc

• Database Design Question: GUID + Natural Numbers

  - by Alan

  For a database I'm building, I've decided to use natural numbers as the primary key. I'm aware of the advantages that GUID's allow, but looking at the data, the bulk of row's data were GUID keys. I want to generate XML records from the database data, and one problem with natural numbers is that I don't want to expose my database key's to the outside world, and allow users to guess "keys." I believe GUID's solve this problem. So, I think the solution is to generate a sparse, unique iD derived from the natural ID (hopefully it would be 2-way), or just add an extra column in the database and store a guid (or some other multibyte id) The derived value is nicer because there is no storage penalty, but it would be easier to reverse and guess compared to a GUID. I'm (buy) curious as to what others on SO have done, and what insights they have.

• Is Java serialization a tool to shrink the memory footprint?

  - by Pentius

  Hey folks, does serialization in Java always have to shrink the memory that is used to hold an object structure? Or is it likely that serialization will have higher costs? In other words: Is serialization a tool to shrink the memory footprint of object structures in Java? Edit I'm totally aware of what serialization was intended for, but thanks anyway :-) But you know, tools can be misused. My question is, whether it is a good tool to decrease the memory usage. So what reasons can you imagine, why memory usage should increase/decrease? What will happen in most cases?

• Question about C# properties

  - by Impz0r

  Hey there, i bumped the other day into a little problem regarding C#'s properties. Let's say i do have this setup: public class Point { public float X; public float Y; } public class Control { protected Point m_Position = new Point(); public Position { get { return m_Position; } set { m_Position = value; } // reorganize internal structure.. reorganize(); } protected reorganize() { // do some stuff } } This is all fine, but when it comes to usage, i could write something like: Control myControl = new Control(); myControl.Position.X = 1.0f; The thing is, my Control class wont recognize that the Position has been changed because set hasn't been called. So i guess my question is, is there a way to make Control aware of any Position changes? Thanks in advance! Mfg Imp

• TCP/IP and UDP Questions and very small application for interview

  - by Shantanu Gupta

  I am going for an interview day after tomorrow where i will be asked vaious questions related to TCP/IP and UDP. As of now i have prepared theoritical knowledge about it. But now I am looking up for gaining some practicle knowledge related to how it works in a network. What all is going in vaious .NET classes. I want to create a very small application like a chat or something that can make me all these concepts very much clear. Could you please suggest some questions related to TCP/IP that you generally ask or that you might have faced. How communication is going from server to client. Right now I am studying TcpClient, TcpListener and UdpClient Class but I want to implement all of them so as to get aware about its working. Is Chat application a Tcp/IP application ? I would appreciate your help.

• MS Access - Keeping track (transacation) of all activity while form is open...

  - by Ron Mac

  Hi and thanks for reading. I am not a database/vba guy and my experience is strictly in the JAVA world. However, I need to have an ACCESS form open. While it is open and new data is entered into it (via the underlying query OR any other data changes in other tables based on sql updates attached to buttons on this form), is there a way that I can initiate a transaction so that at the bottom of the form I could have a button that says "Exit and committ changes" or "Cancel and Rollback changes". I guess I thought of a situation where I could do something like: On Form OPEN, START TRANSACTION On "CLICK OK", COMMIT TRANSACTION or ON "CLICK CANCEL" ROLLBACK. I'm aware how to do the Workspace.BeginTransaction but I'm not sure if that will apply if I do it on FORM OPEN and then on FORM CLOSE do the COMMIT/ROLLBACK locgin? Any insight would be great.

• Which database engines support IP addresses as a native type?

  - by Matt McClellan

  I'm trying to find databases with support for IP addresses as a native type (as opposed to storing as a string, or an unsigned integer, which at least one commenter has already pointed out won't work for IPv6). The primary reason I'm looking for this is ease of development. For example, sorting on a "native" IP address column would be correct (as opposed to when it's stored as a string). I would assume support for such a type would also include useful operations such as determining if an IP address is inside a specified network for use in WHERE clauses. The only one I'm aware of so far is PostgreSQL with its inet class. Does anyone have any others?

• Parsing/executing C# code in C++ (on Linux)?

  - by Stick it to THE MAN

  I want to be able to add scripting functionality to my application. One of the language bindings I am considering is C# (and possibly VB.Net). The challenge is this: My application is developed in C++ My application runs on Linux I am aware of Mono, but I dont know (as yet), what is required to allow my C++ appliaction (running on linux), to be scriptable with .Net languages. Is this feasible? Am I crazy for even thinking of doing this? If I'm not crazy, can anyone provide some guidelines on how to go about implementing this? Help, tips, ideas, suggestions anyone?

• Objective C for Windows

  - by Luther Baker

  What would be the best way to write Objective-C on the Windows platform? Cygwin and gcc? Is there a way I can somehow integrate this into Visual Studio? Along those lines - are there any suggestions as to how to link in and use the Windows SDK for something like this. Its a different beast but I know I can write assembly and link in the Windows DLLs giving me accessibility to those calls but I don't know how to do this without googling and getting piecemeal directions. Is anyone aware of a good online or book resource to do or explain these kinds of things?

• ssrs column groups disable multiple columns

  - by DKS

  I'm using ASP.NET 4.0 Visual Studio 2010 RC version Sql Server Report Services (SSRS) ReportViewer and are aware that columns only display on PDF export - not the preview. I want to use a matrix embedded in a table on a page that has multiple columns. I've done some testing and frustratingly found that if you have a tablix with at least one grouped column (even if there is only one displayed matrix-like column group) the columns seem to be disabled. Once I remove the tablix with a grouped column from the tablix from the report the report does multiple-columns. Does anyone know a way around this?

• How to localize static content in database with Django

  - by man with python

  My app has tables for languages and countries (actually django-countries at the moment, but open for suggestions). The tables are populated when I initialize the database and remain static after that. What would be the ideal localization mechanism for the contents of these tables, so that I can show the country and language names to users in their chosen site language? I'm aware of projects like django-multilingual and transdb, but IMO they are more suitable for dynamic content, i.e. stuff that's supposed to be modified. Please englighten me!

• Kentico - Using punctuation with AuthenticateUser

  - by Big Friendly Giant

  We are currently using version 7.0 of the kentico API to authenticate users into our system. The following code is used to gain user details from the database and authenticate users. UserInfo objUserInfo = AuthenticationHelper.AuthenticateUser(username.ToLower(), password.ToLower(), CMSContext.CurrentSiteName); This has primarily been working correctly, but we are having issues with usernames and passwords that contain any of the following characters. " ! @ ' / \ < * - Is there any settings that I need to be aware of (web.config or otherwise) that would stop the API from accessing an account where a username or password contained special characters?

• Constructor with non-instance variable assistant?

  - by Robert Fischer

  I have a number of classes that look like this: class Foo(val:BasicData) extends Bar(val) { val helper = new Helper(val) val derived1 = helper.getDerived1Value() val derived2 = helper.getDerived2Value() } ...except that I don't want to hold onto an instance of "helper" beyond the end of the constructor. In Java, I'd do something like this: public class Foo { final Derived derived1, derived2; public Foo(BasicData val) { Helper helper = new Helper(val); derived1 = helper.getDerived1Value(); derived2 = helper.getDerived2Value(); } } So how do I do something like that in Scala? I'm aware of creating a helper object of the same name of the class with an apply method: I was hoping for something slightly more succinct.

• Calling software modules (Java, Perl, etc.) from R

  - by harshsinghal

  I've recently started using R for Natural Language Processing tasks and find that a lot of applications are available in Java and Perl (for my purposes). For example: A few perl modules are available to find distance measures between words by querying Wordnet. I am aware of the R Wordnet package, but it does not perform the tasks that these CPAN modules do. Many Java packages for NLP are out there, which I'd like to use from within R. I know of rJava, RSPerl, the simple system command amongst others, but I'd like more examples of how I could make calls to Java and Perl applications from R. Recently I tried capturing console output from a perl script. cat( 'print "Hello World\n";',file="hello.pl" ) system(command="c:\Perl64\bin\perl hello.pl") system(command=paste(Sys.getenv("COMSPEC"),"/c","C:\Perl64\bin\perl hello.pl")) None of the above system commands showed 'Hello World' on the R console. I've used "system" before to run perl scripts to perform tasks without wanting to capture console output. Any hints and redirection to other more extensive sources of information would be highly appreciated. Thank you

• Facebook photo additions showing as separate / individual posts

  - by user1143693

  When posting additional photos to an existing Facebook album, each individual photo is being displayed on the mobile Facebook view as a separate post. Desktop display still groups them (correctly) into 1 album and shows as a single post. For instance, if I add 20 photos to an album, the people who have liked my page will see 20 individual posts in their feed from my account on their mobile devices. This has been happening for about 2 weeks now as far as I've noticed. My upload process has not changed. I should note that I've noticed this behavior by uploading via Lightroom as well as through the direct Facebook interface. Has anyone else experienced this? Did something change that I am not aware of? Thanks.

• SharePoint 2010 - two web applications - single sign on --> do I need claims based auth.?

  - by user333571

  Hi! We are planning to create two sharepoint web applications using SharePoint 2010 Enterprise Edition. All Users that have access to web app 1, should also be able to access web app 2. This authentication shall be powered by server 2003 active directory. -- do I need to use claims based authentication? If so -- can I use Windows Based Authentication with NTLM for that? The only thing I really want is that users navigating from web app 1 to web app 2 (and vice versa) do not have to authenticate twice. I do NOT want to configure Kerberos if it is not absolutely necessare though... Can you give me any hints? Thanks!

• Performance of: if (OBJECT_INSTANCE is TYPE)

  - by Axonn

  I am working both in C# and ActionScript 3. Both language are type-aware, so you can do verifications such as: if (some_object_instance is SomeClassName_ThatIs_SomeType) I'm doing these kind of verifications in a few places. Might be a dumb question, but I will ask it anyway, and I want answers from both camps, C# and ActionScript: What goes on behind the scenes? Is it Reflection? If is, isn't this a long verification which might degrade performance if done in thousands of loops? And by "degrade performance" I mean, is it more intensive than say if (Math.sqrt(8) > Math.sin(10))

• Database triggers / referential integrity and in-memory caching

  - by Ran Biron

  Do you see database triggers / referential integrity rules being used in a way that changes actual data in the database (changing row w in table x causes a change in row y in table z)? If yes, How does this tie-in with the increasing popularity of in-memory caching (memcache and friends)? After all, these actions occur inside the database but the caching system must be aware of them in order to reflect to correct state (or at least invalidate the possibly changed state). I find it hard to believe that callbacks are implemented for such cases. Does anyone have real-world experience with such a setup / real-world experience with considering such a setup and abandoning it (which way did you go? if caching, how do you enforce integrity?)

• Safe to cast pointer to a forward-declared class to its true base class in C++?

  - by Matt DiMeo

  In one header file I have: #include "BaseClass.h" // a forward declaration of DerivedClass, which extends class BaseClass. class DerivedClass ; class Foo { DerivedClass *derived ; void someMethod() { // this is the cast I'm worried about. ((BaseClass*)derived)->baseClassMethod() ; } }; Now, DerivedClass is (in its own header file) derived from BaseClass, but the compiler doesn't know that at the time it's reading the definition above for class Foo. However, Foo refers to DerivedClass pointers and DerivedClass refers to Foo pointers, so they can't both know each other's declaration. First question is whether it's safe (according to C++ spec, not in any given compiler) to cast a derived class pointer to its base class pointer type in the absence of a full definition of the derived class. Second question is whether there's a better approach. I'm aware I could move someMethod()'s body out of the class definition, but in this case it's important that it be inlined (part of an actual, measured hotspot - I'm not guessing).

• What is the best API in any language for Audio and MIDI music application development?

  - by noneme

  What, in your opinion, is the best API to utilize in developing an application that handles both realtime MIDI and audio input and output? This would be for an application that is used in the process of making music as opposed to playing audio or MIDI files. I'm aware that this may be a subjective question, but if you know of an API that is dominantly used for these purposes, please share it. I'm agnostic about which language the API is for, and I also don't care about portability. The real concern is for an API that is well documented, well designed (e.g. thought out and intuitive to developers using it), and actively maintained. OS portability would be nice, but it is second to having an API/Language that meets the previous requirements. Please note that the emphasis is not on API's for sound synthesis or for composing music with code. It is intended for the handling of sound file and MIDI data in a real-time context.

• Which is quicker? Memcache or file query? (using maxmind geoip.dat file)

  - by tomcritchlow

  Hi, I'm using Python on Appengine and am looking up the geolocation of an IP address like this: import pygeoip gi = pygeoip.GeoIP('GeoIP.dat') Location = gi.country_code_by_addr(self.request.remote_addr) (pygeoip can be found here: http://code.google.com/p/pygeoip/) I want to geolocate each page of my app for a user so currently I lookup the IP address once then store it in memcache. My question - which is quicker? Looking up the IP address each time from the .dat file or fetching it from memcache? Are there any other pros/cons I need to be aware of? For general queries like this, is there a good guide to teach me how to optimise my code and run speed tests myself? I'm new to python and coding in general so apologies if this is a basic concept. Thanks! Tom
