• How to program a connection pool?

  - by the_drow

  Is there a known algorithm for implementing a connection pool? If not what are the known algorithms and what are their trade-offs? What design patterns are common when designing and programming a connection pool? Are there any code examples implement a connection pool using boost.asio? Is it a good idea to use a connection pool for presisting connections (not http)? How is threading related to connection pooling? When do you need a new thread?

• Automating builds from subversion tags

  - by Ajaxx

  I'm trying to automate the build process for engineering group. As part of that automation, I'm trying to get to a point where the act of applying a specific tag that adheres to a pattern will kick off an automated process that will do the following: Check out source code Create a build script from a template Build the project I'm pretty certain I could do this with a post-hook in subversion, but I'm trying to figure out a way to do this with something other than a subversion hook. Would it make sense to monitor the tags directory in the subversion repository to kick off my workflow? Are there any decent tools that help with this (.NET would be great if possible). Am I better off just writing an engine to do this? My preferences: Existing product that does all or part of this If development work needs to occur, .NET is preferable Works with Windows (we've got a Linux based repo, but builds all occur on windows)

• Need some help in understanding SSL concepts

  - by user1115256

  I am new to SSL programming and finding some difficulties in understanding SSL concepts. I tried to get it through openssl site,but it is not much informative. Here is my doubts. What is difference between SSL Buffer and BIO buffer..? I mean layerwise detail will be very helpful. Can I use SSL_Write and SSL_Read without setting any BIO object to SSL object..? What exactly BIO_flush will do... I mean is it going to flush all the data to network buffer from BIO buffer.. ? If it is possible to do write and read data from SSL directly without using any BIO object then is it possible to flush the data from SSL buffer to network buffer by any means.. ? It would be very helpful if any body explain these things or giving any links where I can find answers to my questions.

• C++ Boost bind value type

  - by aaa

  hello. I look in documentation and source code but cannot figure out how to get return value type of boost bind functor. I am trying to accomplish following: 35 template<typename T,size_t N, class F> 36 boost::array<typename F::value_type, N> make_array(T (&input)[N], F unary) { 37 boost::array<typename F::value_type, N> array; 38 std::transform(input, input + N, array.begin(), unary); 39 return array; 40 } where F can be bind functor. the above does not work because functor does not have value_type. for that matter, is there standard interface for unary/binary functor as far as return value. Thanks

• Is It Worth Using Bitwise Operators In Methods?

  - by user1626141

  I am very new to Java (and programming in general, my previous experience is with ActionScript 2.0 and some simple JavaScript), and I am working my way slowly and methodically through Java: A Beginner's Guide by Herbert Schildt. It is an incredible book. For one thing, I finally understand more-or-less what bitwise operators (which I first encountered in ActionScript 2.0) do, and that they are more efficient than other methods for certain sums. My question is, is it more efficient to use a method that uses, say, a shift right, to perform all your divisions/2 (or divisions/even) for you in a large program with many calculations (in this case, a sprawling RPG), or is it more efficient to simply use standard mathematical operations because the compiler will optimise it all for you? Or, am I asking the wrong question entirely?

• Library for Dataflow in C

  - by msutherl

  How can I do dataflow (pipes and filters, stream processing, flow based) in C? And not with UNIX pipes. I recently came across stream.py. Streams are iterables with a pipelining mechanism to enable data-flow programming and easy parallelization. The idea is to take the output of a function that turns an iterable into another iterable and plug that as the input of another such function. While you can already do this using function composition, this package provides an elegant notation for it by overloading the operator. I would like to duplicate a simple version of this kind of functionality in C. I particularly like the overloading of the operator to avoid function composition mess. Wikipedia points to this hint from a Usenet post in 1990. Why C? Because I would like to be able to do this on microcontrollers and in C extensions for other high level languages (Max, Pd*, Python). * (ironic given that Max and Pd were written, in C, specifically for this purpose – I'm looking for something barebones)

• Laying out JPanels to make a simple GUI

  - by Elvis

  Hello, first of all, this is more or less my first GUI and ive learned Java for not more then a week, so it might contain some serious programming errors. What i have right now is: Buttons and labels are part of OptionPanel and are on the left, DrawingPanel is about 5x5 px in size and is on the right. What I am trying to do is a simple test, to get me more familiar with the GUI. The rectangle should be movable and re-sizeable by the user when clicking the respective buttons: http://www.upload.ee/image/612005/JFrame2.jpg Right now i have: JFrame MainFrame - Makes JFrame (Not using the setSize function. using .pack() instead. not sure about it) JPanel MergedPanel - FlowLayout - Adds JPanel OptionsPanel and JPanel DrawingPanel together and gets injected to JFrame MainFrame JPanel DrawPanel - This JPanel is responsible of drawing the rectangle.

• How to replace a codebehind method with an aspx method using ternary operator

  - by user466663

  I have an asp:hyperlink control as part of a gridview template. The code in the aspx page is given below: asp:HyperLink runat="server" ID="lnkEdit" ToolTip="Edit article" NavigateUrl='<%# GetUrl(Eval("ID").ToString(), Eval("CategoryID").ToString()) %' ImageUrl="~/Images/Edit.gif" The NavigateUrl value is obtained from the codebehind method GetUrl(string, string). The code works fine and is as follows: protected string GetUrl(string id, string categoryID) { var CategoryID = string.Empty; if (!String.IsNullOrEmpty(Request.QueryString["CatID"])) { CategoryID = Request.QueryString["CatID"].ToString(); } else if (!String.IsNullOrEmpty(categoryID)) { CategoryID = categoryID; } return "~/TBSArticles/WriteOrEditArticle.aspx?ID=" + id + "&CatID=" + CategoryID; } I want to replace the code behind method by using a ternary operator within the aspx page. I tried something like below, but didn't work: asp:HyperLink runat="server" ID="lnkEdit" ToolTip="Edit article" NavigateUrl='<%# "~/TBSArticles/WriteOrEditArticle.aspx?ID=" + Eval("ID") + "&CatID=" + Eval(this.Request.QueryString["CatID"].ToString()) != ""? this.Request.QueryString["CatID"] : Eval("CategoryID")) %' ImageUrl="~/Images/Edit.gif" Any help will be greatly appreciated. Thanks

• How should I structure my iPhone OpenGL ES 1.1 game?

  - by Ryan

  I am building an iPhone OpenGL ES 1.1 game. I am using the OpenGL ES template provided by xcode. I am only using the ES1Renderer. I've coded some basic touch actions the user can take, and I've begun to think about the overall structure of the code. All I'm really doing is using C in the ES1Renderer.m for my entire game state. I have an array of bullet structs, an array on enemy structs, etc.. Besides using this structure, where my entire game state is in ES1Renderer.m as C arrays and structs, what other ways are there to structure the code? Should I be using C++ or Objective-C classes to represent the enemies so they are more modular? The main reason I ask this is because I don't normally code in C, C++ and Objective-C..so I am a little fuzzy on coming up with a good architecture here.

• Best Online C++ Refresher

  - by Bill

  It's been a longtime since I've done any C++ (probably about 13 years, since I graduated college). I've developing in various others languages since then. My new gig uses a fair bit of C++. Any recommendations for getting bootstrapped? To clarify -- I don't need an "into to programming" book. E.g., what's a variable, flow control, etc. I understand the concepts of OO having implemented them, etc. I'm looking for the best way to get to the specifics of C++.

• grouping objects to achieve a similar mean property for all groups

  - by cytochrome

  I have a collection of objects, each of which has a numerical 'weight'. I would like to create groups of these objects such that each group has approximately the same arithmetic mean of object weights. The groups won't necessarily have the same number of members, but the size of groups will be within one of each other. In terms of numbers, there will be between 50 and 100 objects and the maximum group size will be about 5. Is this a well-known type of problem? It seems a bit like a knapsack or partition problem. Are efficient algorithms known to solve it? As a first step, I created a python script that achieves very crude equivalence of mean weights by sorting the objects by weight, subgrouping these objects, and then distributing a member of each subgroup to one of the final groups. I am comfortable programming in python, so if existing packages or modules exist to achieve part of this functionality, I'd appreciate hearing about them. Thank you for your help and suggestions.

• iPhone/iPad fatal error in C++ code produces no output in the log

  - by morgancodes

  I'm trying to move away from Objective-C to C++ for audio in my iPad programming, due to the a few reports I've heard of Objective-C selectors sometimes causing audio glitches. So I'm starting to use pure C++ files. When a fatal error happens in one of the C++ files, I get no output from the log. The app just crashes. For example, if I do this in my C++ file: env = new ADSR(); cout << "setting env to null\n"; env = NULL; env->setSustainLevel(1); cout << "called function on non-initialized env\n"; I get the following output: setting env to null After that, there's a method called on NULL, which apparently kills the app, but absolutely nothing to that effect is reported. What do I need to do to have useful information logged when there's an error in my C++ code?

• Conditionally setting the font color of an item in a drop down box in JSF

  - by Greg

  I'm a newbie to web programming, so please bear with me. I am using JSF 1.2 and I want to conditionally set the color of the items in my drop down list. In other words, I have a collection of items that, along with a key and a value, also have a boolean property, warning, that is dynamically set by user action. I want the drop down to show all of the items, but those whose warning property is set to true should be displayed in red. I assume I have to extend the SelectItem class to add in the boolean property. How do I then conditionally set the color of the font of those items whose warning property is set to true in my JSP pages? Thanks in advance

• file_get_contents() removing tab and new line characters

• What are 3 C++ language features you expect AFTER C++0x?

  - by Vicente Botet Escriba

  If I have understood well C++0x is now on a phase to resolve pending issues, so no new features will be added. What I want to know is what new features you want to have in C++ after C++0x is released. Just to give you an idea, I have added major existing proposal that could be included after C++0x: Concepts, Contract Programming, Garbage Collection, Macro scopes, Modules, Multimethods, Reflection Answer with your favorite feature if not already in an answer and up-vote them if already present. Be free to add other features not included on this list. Please don't include here libraries. Only core language features.

• How do you manage battery health of your development devices when is always plugged in?

  - by Pentium10

  I know this question is not programming related, so for this I made community wiki. Developers are the best guys to answer the question. I am addressed to those that do development on devices that runs on batteries, like phones, gadgets etc. Probably you are constantly develop for them, and therefor they are always plugged in and charged at 100%. We develop mainly for smartphones and we have devices that were always above 90% charged in the last month or so. If a battery is always charged, it degrades it life cycle, so what steps you do to ensure decent battery drain to maximize the life of the batteries.

• Ideas on limiting content to single printed page?

  - by James Skidmore

  I have 5-6 text areas that users fill out in a template (a couple of columns, basically a newsletter format). I'm needing to limit their content to one printed page, but I'm having a hard time coming up with practical solutions. The printed format (margin, font size, etc.) will be the same for all users, as it's printed from a central source. I've had a couple of ideas, but all of them seem rather unreliable and difficult to implement: Determine height of content using JavaScript and estimate the number of printed pages from that. The problem with this is that browser font sizes can vary, it's only a rough estimate (pixels to inches), etc. Limit the number of characters. This is problematic because there are various text fields, certain characters (like M) take up more space than others (like I), and line breaks obviously count for much more. What ideas do you all have? I appreciate your help!

• Compiler construction and DirectX

  - by otkins

  Hi! I am a beginner in the process of designing and coding a project, I already have all the ideas on my head, but I have a problem impeding me of continuing this project. I feel the code is ugly and unreadable and I cannot continue it this way. The project is a programming language I have on my mind, and it has small graphics capabilities. Even being beginner, I want to code it using DirectX because everybody wants it. And I want to code it entirely, not depend on any wrapper libraries like SDL. I did a refactoring of the DirectX module and it exposed all the weaks. There is Direct3D code everywhere, but the code itself does very little! I would start building a project like this using DirectX or I should use just GDI and the Multimedia API of Windows? This is a good progress for a beginner?

• VBA long overflow

  - by HK_CH

  Hi I am trying to do some maths with my VBA excel (prime factorization) and I am hitting the limit of the long data type (runtime error 6 Overflow). Is there any way to get around this and still stay within VBA? (I am aware that the obvious one would be to use another more appropriate programming language) Thanks for help in advance! Thank you, it works in so far that I am able to get the big numbers into the variables now. However when I try to apply the MOD function (bignumber MOD 2 for example) it still fails with error message runtime error 6 Overflow.

• C#: Basic Reflection Class

  - by Mike

  I'm trying to find a basic reflection abstract class that will generate basic information about a class. I have a template of how I would like it to work: class ThreeList<string,Type,T> { string Name {get; set;} Type Type {get; set;} T Value {get; set;} } abstract class Reflect<T> { List<ThreeList<string, Type, T> list; ReturnType MethodName() { foreach (System.Reflection.PropertyInfo prop in this.GetType().GetProperties()) { object value = prop.GetValue(this, new object[] { }); list.Add(prop.Name, prop.DeclaringType, value); } } } I'd like it to be infinitely deep, recursively calling Reflect. Something like this has to exist. I'm not really opposed to coding it myself, I just don't want to go through the hassle if its already been done.

• prevent linux thread from being interrupted by scheduler

  - by johnnycrash

  How do you tell the thread scheduler in linux to not interrupt your thread for any reason? I am programming in user mode. Does simply locking a mutex acomplish this? I want to prevent other threads in my process from being scheduled when a certain function is executing. They would block and I would be wasting cpu cycles with context switches. I want any thread executing the function to be able to finish executing without interruption even if the threads' timeslice is exceeded.
