• Webservice and ORM Framework?

  - by Sebastian

  Does anybody know a good web framework that includes an ORM mapper and allows straight forward implementation of web services? I'm looking for a framework written in PHP or C++. I'm looking for the following features (not all of them required, some will do nicely) data definition in one place used by database and web service WSDL generation XML output/JSON output boilerplate code generation So what I would like is a framework that let's me specify the objects, the web service functions on those objects and then generate everything that is required leaving me to fill the business logic (connecting the database to the web service). Anything like that out there? Background information for why I need this: I'm looking into creating a web project: the client is a rich web application that fetches all its data using AJAX. It will be completely custom made using only a low level javascript library. The server back end is supposed to serve static content and javascript (basically the rich web application) and to provide a RESTful web service API (which I would like to implement using aforementioned framework).

• Reverse Bredth First Search in C#

  - by Ngu Soon Hui

  Anyone has a ready implementation of the Reverse Bredth First Search algorithm in C#? By Reverse Bredth First Search, I mean instead of searching a tree starting from a common node, I want to search the tree from the bottom and gradually converged to a common node. Let's see the below figure, this is the output of a Bredth First Search: In my reverse bredth first search, 9,10,11 and 12 will be the first few nodes found ( the order of them are not important as they are all first order). 5, 6, 7 and 8 are the second few nodes found, and so on. 1 would be the last node found. Any ideas or pointers?

• fluent nhibernate not caching queries in asp.net mvc

  - by AWC

  I'm using a fluent nhibernate with asp.net mvc and I not seeing anything been cached when making queries against the database. I'm not currently using an L2 cache implementation. Should I see queries being cached without configuring an out of process L2 cache? Mapping are like this: Table("ApplicationCategories"); Not.LazyLoad(); Cache.ReadWrite().IncludeAll(); Id(x => x.Id); Map(x => x.Name).Not.Nullable(); Map(x => x.Description).Nullable(); Example Criteria: return session .CreateCriteria<ApplicationCategory>() .Add(Restrictions.Eq("Name", _name)) .SetCacheable(true); Everytime I make a request for an application cateogry by name it is hitting the database is this expected behaviour?

• Receiving a File via RFCOMM on Android

  - by poeschlorn

  Hey guys, does someone know how to receive a file on android via RFCOMM? I'm a newby to bluetooth issues, so please have patience with me. I'm looking for an approach to receive data via RFCOMM as a stream and store it somewhere on my phone. Saving data is not the problem, it works quite fine. The main issue is the implementation of the connection and the reliable retrieval of the data... This whole procedure should be implemented as an android service (so that no activity has to be launched while receiving data). What would you suggest: Local or remote service? greetz, poeschlorn

• Arrays in javascript, how can i learn manipulating it?

  - by Noor

  I've read alot about the core implementation of arrays in javascript and often i find that experimenting is the best way to learn, Right now i have multiple forms where you can type in different things, i want to be able to pull the value of each one and put it in an array so that i can later on read them in in a dynamically created div.. Can anyone point me in the right direction? There is a way i could get around this and that would be by using just one form, and pulling the text from there seperated by comas (,).. the thing is that i don't have the knowledge to pull the text form the form, search and find the comas, then make a new variable i think is neccessary, and read that in.. i know how to "think" javascript, not how to write it.. how do i learn the easiest/fastest way?

• View plain text files with different background colors in Mac OSX, for different programming languag

  - by Werner

  Hi, I work with Mac OS X Leopard. I usually have 5 or 10 text files opened at the same time with different programming languages; one for a bash script, another for a python one, etc. When I use exposé all of them look the same, so it is difficult to select them. I wonder how could I work with just plain text files in OSX, so when they are opened in an editor the background color changes or some other thign, so when using exposé it is clear to me which window belongs to what language. I thought about inserting some kind of info to the last line of each document, and then creat some applescript that converts it to RTF or someother text document which includes color in bacjground, so then it is opened with textmate or someother app. Do you know a better approach for this? Thanks

• Reject (Hard 404) ASP.NET MVC-style URLs

  - by James D

  Hi, ASP.NET MVC web app that exposes "friendly" URLs: http://somesite.com/friendlyurl ...which are rewritten (not redirected) to ASP.NET MVC-style URLs under the hood: http://somesite.com/Controller/Action The user never actually sees any ASP.NET MVC style URLS. If he requests one, we hard 404 it. ASP.NET MVC is (in this app) an implementation detail, not a fundamental interface. My question: how do you examine an arbitrary incoming URL and determine whether or not that URL matches a defined ASP.NET MVC path? For extra credit: how do you do it from inside an ASP.NET-style IHttpModule, where you're getting invoked upstream from the ASP.NET MVC runtime? Thanks!

• How does compilation work with AOP?

  - by alee

  I need quick answer to a simple thing in AOP. If i have a code deployed at client side and i have written new aspects, which i want in the client side software. do i have to "recompile" complete software with "original" code and new "AOP" code? (with aop compiler)? i.e. do i need the source code of original program with source code of new AOP and compile 'em boht? P.S: I am asking in general, not being specific to any language.

• Java Program Design Layout Recommendations?

  - by Leebuntu

  I've learned enough to begin writing programs from scratch, but I'm running into the problem of not knowing how to design the layout and implementation of a program. To be more precise, I'm having difficulty finding a good way to come up with an action plan before I dive in to the programming part. I really want to know what classes, methods, and objects I would need beforehand instead of just adding them along the way. My intuition is leading me to using some kind of charting software that gives a hierarchal view of all the classes and methods. I've been using OmniGraffle Pro and while it does seem to work somewhat, I'm still having trouble planning out the program in its entirety. How should I approach this problem? What softwares out there are available to help with this problem? Any good reads out there on this issue? Thanks so much! Edit: Oh yeah, I'm using Eclipse and I code mainly in Java right now.

• Ideas for Computer Science related Microteaching

  - by Roman Stolper

  This semester, I will be a TA for an introductory computer science course at my university. As part of TA training, I'll be doing something called Microteaching, which is where I teach for 5-7 minutes in front of a small audience (4-5 people) and I am reviewed on my teaching style. Among being critiqued on my personal things like confidence and eye contact, I will be critiqued on how well I know the subject material, as well as how interesting it is to the audience. So my question is: Can you offer me any suggestions of computer science related topics that: I can begin and finish teaching in a span of 5-7 minutes Are fun to learn about Are accessible to a general engineering (but not necessarily computer science) audience Some topics I have considered: Teaching how to write Hello World in some simple language Introducing a synchronization problem like dining philosophers

• 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.

• Scoping in embedded groovy scripts

  - by Aaron Digulla

  In my app, I use Groovy as a scripting language. To make things easier for my customers, I have a global scope where I define helper classes and constants. Currently, I need to run the script (which builds the global scope) every time a user script is executed: context = setupGroovy(); runScript( context, "global.groovy" ); // Can I avoid doing this step every time? runScript( context, "user.groovy" ); Is there a way to setup this global scope once and just tell the embedded script interpreter: "Look here if you can't find a variable"? That way, I could run the global script once. Note: Security is not an issue here but if you know a way to make sure the user can't modify the global scope, that's an additional plus.

• LLBLGen and the repository pattern

  - by user137348

  I was wondering if building a repository on the top LLBLGen (adapter) is a good idea. I don't want to overengineer and reinvent the wheel again. The DataAccessAdapter class could be some kind of a generic repository.It has all the CRUD methods you need. But on the other side for a larger project it could be good to have a layer between your ORM and service layer. I'd like to hear your opinions, if your using the repository pattern with LLBLGen,if yes why if no why not. If you have some implementation, post it please.

• Suggestion for creating custom sound recognition software to toggle audio

  - by Parrot owner

  I need to develop a program that toggles a particular audio track on or off when it recognizes a parrot scream or screech. The software would need to recognize a particular range of sounds and allow some variations in the range (as a parrot likely won't replicate its sreeches EXACTLY each time). Example: Bird screeches, no audio. Bird stops screeching for five seconds, audio track praising the bird plays. Regular chattering needs to be ignored completely, as it is not to be discouraged. I've heard of java libraries that have speech recognition with dictionaries built in, but the software would need to be taught the particular sounds that my particular parrot makes - not words or any random bird sound. In addition as I mentioned above, it would need to allow for slight variation in the sound, as the screech will likely never be 100% identical to the recorded version. What would be the best way to go about this/what language should I look into?

• What's a better choice for SQL-backed number crunching - Ruby 1.9, Python 2, Python 3, or PHP 5.3?

  - by Ivan

  Crterias of 'better': fast im math and simple (little of fields, many records) db transactions, convenient to develop/read/extend, flexible, connectible. The task is to use a common web development scripting language to process and calculate long time series and multidimensional surfaces (mostly selectint/inserting sets of floats and dong maths with rhem). The choice is Ruby 1.9, Python 2, Python 3, PHP 5.3, Perl 5.12, JavaScript (node.js). All the data is to be stored in a relational database (due to its heavily multidimensional nature), all the communication with outer world is to be done by means of web services.

• How to implement file transfer with Java sockets?

  - by ZeKoU

  Hello, I am working on a chat implementation with Java sockets. I have focused on few functionalities, like authentication, one person chat and a group chat. I was thinking about adding file transfer functionality, and I wonder what's the good practice about this. Should I have separate socket on the server with different port listening just for file transfers? Right now input and output streams that I get from server socket are binded to Scanner and PrintWriter objects respectively, so I find it hard to use that for file transfer. Any patterns you guys could recommend or give me good recommendations are very appreciated. Thanks, ZeKoU

• Untrusted GPGPU code (OpenCL etc) - is it safe? What risks?

  - by Grzegorz Wierzowiecki

  There are many approaches when it goes about running untrusted code on typical CPU : sandboxes, fake-roots, virtualization... What about untrusted code for GPGPU (OpenCL,cuda or already compiled one) ? Assuming that memory on graphics card is cleared before running such third-party untrusted code, are there any security risks? What kind of risks? Any way to prevent them ? (Possible sandboxing on gpgpu or other technique?) P.S. I am more interested in gpu binary code level security rather than hight-level gpgpu programming language security (But those solutions are welcome as well). What I mean is that references to gpu opcodes (a.k.a machine code) are welcome.

• is PHP itself transforming into a framework?

  - by Elzo Valugi

  At the beginning PHP was a scripting language. But after the introduction and improvement of OOP I see more and more objects added to the core. They started with SPL which grew a lot, now we have DOMDocument family, DateTime family which should be part of PECL, Pear or Zend Framework or implemented by each one of us. Shouldn't be php only for build-in functions and all these objects passed to something else? Example. DateTime class is part of the core and I see it very similar with Zend_Date.

• Custom SQL Server driver

  - by hoodoos

  I had a crazy thought about writing my own SQL Server driver to make it work something like non-blocking http client, so it won't be thread thirsty and could handle lots of db queries within one thread. I tried to look over google for some guidelines about implementing SQL Server client protocol, but found none really, where do those guys get information about it when they write own implementations for PHP or python? I need a really low level to be documented so I can implement all phases of working with a connection through sockets. And would be really nice to have a an example in c# language. :)

• How to handle splitting a file under source control?

  - by sharptooth

  I have a .cpp file and .h file containing a class. Class.cpp contains the implementation and Class.h contains the definition. The class is overcomplicated so I want to separate some code and move it into a separate class. So I create NewClass.cpp and NewClass.h and move the code there. How do I handle this when the files are under SVN? I can simply "svn add" the two new files, but then they will appear as new and will have no history. I could instead "svn copy and rename" the two initial files and edit the the two old files and the two new files - then the two new files will have common history. Which approach is better from the point of version control? Should the new files share history with the old files or should they appear as new?

• Using the system localizations on iPhone

  - by nevan

  I want to make a back button for a navigation controller with the title "Back" instead of the title of the previous controller. I'm using this code: UIBarButtonItem *backButton = [[UIBarButtonItem alloc] initWithTitle:NSLocalizedString(@"Back", @"Back") style:UIBarButtonItemStyleBordered target:nil action:nil]; self.navigationItem.backBarButtonItem = backButton; I'd like to be able to skip localizing the "Back" string in my app (since I can only localize it in a limited number of languages). If I give my navigation controller no title, the back button will be automatically localized into whatever the language the user has chosen, so the system has translations of "Back" in many languages. Is there a way to access the localizations that are already present in the system and use them myself? These are things like "Back", "Cancel", "Done" and so on, which show up when creating one of the standard system buttons.

• tinyMce reloading data with html tags

  I'm having issue with TinyMCE. After saving the contents of the editor and redisplaying it all the HTML tags are visible. This is how I'm initializing the editor: // Tinymce Config tinyMCE.init({ // General options mode : "specific_textareas", editor_selector : "mceEditor", language : "<?php echo $tinyMceLang?>", setup : function(ed) { ed.onActivate.add(tinyOnEdit); }, theme : "advanced", plugins : "table", // Theme options theme_advanced_buttons1 : "bold,italic,underline,strikethrough,|,justifyleft,justifycenter,justifyright,justifyfull,fontsizeselect,|,forecolor,backcolor,|,table,row_before,row_after,delete_row,col_before,col_after,delete_col,code", theme_advanced_buttons2 : "", theme_advanced_buttons3 : "", theme_advanced_buttons4 : "", theme_advanced_toolbar_location : "top", theme_advanced_toolbar_align : "left", theme_advanced_statusbar_location : "bottom", theme_advanced_path : false, theme_advanced_resizing : true, convert_fonts_to_spans : true, //font_size_style_values : "0.7em,0.8em,1em,1.2em,1.5em,2em,3em", //font_size_style_values : "8pt,10pt,12pt,14pt,18pt,24pt,36pt", // content CSS (should be your site CSS) content_css : "/css/tiny_content.css" }); if i paste a content like this (With HTML tags): "testing tinymce contents" redisplayed as : "testing tinymce contents" but excepted result is : testing tinymce contents (Text with red color)(Not allowing html tags)

• Fast parsing of PHP in C#

  - by Jessica Shea

  Hello there, I've got a requirement for parsing PHP files in C#. We essentially require some of the devs in another country to upload PHP files and once uploaded we need to check the php files and get a list of all the methods and classes/functions etc. I thought of using a regex but I can't workout if a function belongs to a class etc, so I was wondering if theres already something 'out there' that will parse out PHP files and spit out its functions (I'm trying to avoid writing a full blow AST implementation). Does anyone have any idea? I looked at Coco/R but I couldn't find a PHP grammar file. I'm using .NET 2.0 and C#.
