  - by Matachana

• Any PHP MVC framework planning to use 5.3 features?

  - by alexandrul

  I would like to get started with PHP, and 5.3 release seems to bring many nice features (namespaces, lambda functions, and many others). I have found some MVC frameworks, and some of them support only PHP 5: PHP Frameworks PHP MVC Frameworks Model–view–controller on Wikipedia but can anyone recommend one of those MVC frameworks that plans to actively use PHP 5.3 features, not just being compatible with PHP 5.3? Update Results so far: Zend Framework 2.0 (in development) Lithium (in development, based on CakePHP) Symfony (in development) FLOW3 (in development, alpha)

• VB.NET Function Return

  - by waves

  In order to return a value from a VB.NET function one can assign a value to the "Functions Name" or use "return value." I sometimes see these inter-mixed in the same function. Personally, I prefer the return. My question is, what is the internal difference, if any, between the two?

• C++ Thread level constants

  - by Gokul

  Is there a way by which we can simulate thread level constants in C++? For example, if i have to make a call to template functions, then i need to mention the constants as template level parameters? I can use static const variables for template metaprogramming, but they are process level constants. I know, i am asking a question with a high probability of 'No'. Just thought of asking this to capitalize on the very rare probability :)) Thanks, Gokul.

• Dealing with &rest-parameters in common lisp

  - by Patrick

  I want define a functions that accepts &rest - parameters and delegates them to another function. (html "blah" "foo" baz) = "blahfoobaz" I did not find a better way than this one: (defun html (&rest values) (concatenate 'string "" (reduce #'(lambda(a b) (concatenate 'string a b)) values :initial-value "") "")) But this looks somewhat glumbsy to me, since line 4 does no more than concatenating the &rest parameter "values". I tried (concatenate 'string "" (values-list values) "") but this does not seem to work (SBCL). Could someone give me an advice? Kind regards

• String Compression using Lempel-Ziv

  - by roybot

  Im looking for a way of compressing a given string using the Lempel-Ziv Algorithm. Preferably there would only be a set of two functions, encoder and decoder. The encoder takes the string and returns an integer. The decoder takes the integer and returns the original string. Time complexity is not important. How would you implement this?

• Performance Cost of a Memcopy in C/C++

  - by Cenoc

  So whenever I write code I always think about the performance implications. I've often wondered, what is the "cost" of using a memcopy relative to other functions in terms of performance? For example, I may be writing a sequence of numbers to a static buffer and concentrate on a frame within the buffer, in order to keep the frame once I get to the end of the buffer, I might memcopy all of it to the beginning OR I can implement an algorithm to amortize the computation.

• Aggregate analog of row count component?

  - by JSacksteder

  I'd like to have a way to get the sum of a field stored into a variable from inside a dataflow task. The rowcount transform does this, but I can't see how to use any other aggregate functions. Is scripting a transform component my best bet?

• Can you turn a Haskell list into a series of do instructions?

  - by toofarsideways

  Can you create a list of functions and then execute them sequentially, perhaps passing them into do notation? I'm currently doing this by mapping over a list of data and am wondering if I can call somehow pass the result as a series of sequential calls?

• deep or shallow copying?

  - by Dervin Thunk

  Dear all. I was wondering if there are examples of situations where you would purposefully pass an argument by value (deep copy) in C. For instance, passing a char to a function is usually cheaper in space than passing a char* (if there's no need to share the value), since char is 1 byte and pointers are, well, whatever they are in the architecture (4 in my 32 bit machine). ?(When) do you want to pass (big) deep copies to functions? if so, why?

• How to execute a program from file descriptor?

  - by stribika

  I need to execute a file when I only know the descriptor. It is also possible that there are no links to the file so finding out the name somehow is not an option. All the execve(), execvp(), etc functions take a file name. dlopen() also takes a name. Ugly solutions (like reading the file and calling some function pointer) are OK.

• looking for a javascript engine

  - by c0f33.alex

  i'm looking for a js engine to that I can (easily) expose C/C++ functions, classes etc. The API should allow changing exposed values from within C++ (by storing some kind of pointer or reference to an object inside js or so...). I've considered using google's v8 but I'm new to it and don't know whether it will satisfy my requirements. Can someone tell me whether I should stick to v8 or try something else?

• Cross platform millisecond timer lasting more than 49 days?

  - by Cetra

  Hey guys, I'm going to be developing a small dedicated server in C/C++ that will require uptime of forever. I've been looking into some time functions as millisecond timing is required for calculations. I have 2 problems that I'm facing: Using a 32bit integer to store the number of milliseconds since the operation began will wrap around at about the 49 days mark resetting to zero. There doesn't seem to be any standard system calls for getting elapsed milliseconds that are platform independant What should I do to resolve both these issues?

• C#: Can you detect whether or not the current execution context is within `lock (this)`?

  - by John Gietzen

  If I have an object that I would like to force to be accessed from within a lock, like so: var obj = new MyObject(); lock (obj) { obj.AddOne(); obj.RemoveOne(); } Is it possible, from within the AddOne and RemoveOne functions to detect whether the current execution context is within a lock? Something like: Monitor.AreWeCurrentlyEnteredInto(this)

• Is a Multi-DAL Approach the way to go here?

  - by Krisc

  Working on the data access / model layer in this little MVC2 project and trying to think things out to future projects. I have a database with some basic tables and I have classes in the model layer that represent them. I obviously need something to connect the two. The easiest is to provide some sort of 'provider' that can run operations on the database and return objects. But this is for a website that would potentially be used "a lot" (I know, very general) so I want to cache results from the data layer and keep the cache updated as new data is generated. This question deals with how best to approach this problem of dual DALS. One that returns cached data when possible and goes to the data layer when there is a cache miss. But more importantly, how to integrate the core provider (thing that goes into database) with the caching layer so that it too can rely on cached objects rather than creating new ones. Right now I have the following interfaces: IDataProvider is used to reach the database. It doesn't concern itself with the meaning of the objects it produces, but simply the way to produce them. interface IDataProvider{ // Select, Update, Create, et cetera access IEnumerable<Entry> GetEntries(); Entry GetEntryById(int id); } IDataManager is a layer that sits on top of the IDataProvider layer and manages the cache interface IDataManager : IDataProvider{ void ClearCache(); } Note that in practice the IDataManager implementation will have useful helper functions to add objects to their related cache stores. (In the future I may define other functions on the interface) I guess what I am looking for is the best way to approach a loop back from the IDataProvider implementations so that they can access the cache. Or a different approach entirely may be in order? I am not very interested in 3rd party products at the moment as I am interested in the design of these things much more than this specific implementation. Edit: I realize the title may be a bit misleading. I apologize for that... not sure what to call this question.
