  • When to trash hashmap contents to avoid performance degradation?

    - by Jack
    Hello, I'm woking on Java with a large (millions) hashmap that is actually built with a capacity of 10.000.000 and a load factor of .75 and it's used to cache some values since cached values become useless with time (not accessed anymore) but I can't remove useless ones while on the way I would like to entirely empty the cache when its performance starts to degrade. How can I decide when it's good to do it? For example, with 10 millions capacity and .75 should I empty it when it reaches 7.5 millions of elements? Because I tried various threshold values but I would like to have an analytic one. I've already tested the fact that emping it when it's quite full is a boost for perfomance (first 2-3 algorithm iterations after the wipe just fill it back, then it starts running faster than before the wipe) Thanks

  • syntax to express mathematical formula concisely in your language of choice

    - by aaa
    hello. I am developing functional domain specific embedded language within C++ to translate formulas into working code as concisely and accurately as possible. Right now my language looks something like this: // implies two nested loops j=0:N, i=0,j (range(i) < j < N)[T(i,j) = (T(i,j) - T(j,i))/e(i+j)]; // implies summation over above expression sum(range(i) < j < N))[(T(i,j) - T(j,i))/e(i+j)]; I am looking for possible syntax improvements/extensions or just different ideas about expressing mathematical formulas as clearly and precisely as possible. Can you give me some syntax examples relating to my question which can be accomplished in your language of choice which consider useful. In particular, if you have some ideas about how to translate the above code segments, I would be happy to hear them Thank you

  • CSS cross browser compatibility on Ubuntu

    - by bhefny
    Hello, I'm currently working in web development and my default desktop is Ubuntu and I'm kind of happy with the setup and applications I got going. But I need to test web pages for cross browser compatibility while still being on Ubuntu. I have gone through hell trying to get IE7 or IE8 (with wine) to run on ubuntu and when they finally worked they were very buggy and the graphics/scrolling was insanely slow. Of course there is the option of virtual box but again, too much GBytes just to run a small application! So to all the CSS gurus out there, how can I continue with my beloved Ubuntu and still deliver a good quality (tested) page. Thank you.

  • Web page with embedded .NET control in IBM WebSphere 6.1

    - by Borat
    Hello, I have very simple web page with embedded .NET control in it via the <object> tag. The problem is that when I deploy it to an IIS server it works fine (the .NET control is shown). The same is for the Apache server. But when I deploy it to the WebSphere server I get the html but the .NET control does not appear. Probably it is some kind of a server configuration issue, but I cannot figure it out. I would appreciate any suggestions. Best regards!

  • Binding to a List<object> in silverlight problem.

    - by cw
    Hello, Can someone suggest what I am doing wrong? Basically I have a List Items, when an item gets added to the list I am resetting the collection to the viewmodel property. The only way I can get it to work is if I null the member object out before reassigning the binding. Any suggestions on how to go about updating a UI when an item gets added to a List? public List<Item> RegisteredItems { get { return m_vRegisteredItems; } set { m_vRegisteredItems= null; NotifyPropertyChanged("RegisteredItems"); m_vRegisteredItems= value; NotifyPropertyChanged("RegisteredItems"); } }

  • C++ template parameter/class ambiguity

    - by aaa
    hello. while testing with different version of g++, the following problem came up template<class bra> struct Transform<bra, void> : kernel::Eri::Transform::bra { static const size_t ni = bra::A::size; bra::A is interpreted as kernel::Eri::Transform::bra::A, rather than template argument by g++ 4.1.2. on the other hand, g++ 4.3 gets it right. what should be correct behavior according to standard? Meanwhile, I refactor slightly to make problem go away.

  • Call function from hyperlink defined in qTip content

    - by user327066
    Hi, I am trying to call a javascript function from a hyperlink that is part of the content in a qTip. I keep getting the error my function is not defined but it is defined within the page and can be called outside of qTip. Below is what I have so far: function addTooltip() { $("#mycontent").qtip({ content: 'mylink' }); } function tester() { alert("hello world"); } If I put the alert within the onClick attribute, I at least get the alert to work. Is there some special way of calling a function from within qTip? Any help is appreciated. Thanks.

  • playing flv in website

    - by samoyed
    hello to all, my client wants to play a flash video in their website. just to make sure i understand correctly, i need to: 1. create an FLV file 2. use either some flv player or wrap the flv inside swf questions: 1. the player option - will visitor have to download /install it or is it install only once, in the website itself? any FREE player you can recommend the will ensure cross browser compatibility? swf option: will i need the flash application in order to do the wrapping? will i be able to later use something like flashobject library for the actual embedding? what are the main considerations for choosing between the two options , if indeed these are the options? any help would be highly appreciated. have a nice day and let's pray for a lot of goals today :-)

  • General approach for posting business logic status messages to UI?

    - by generalt
    Hello all. I have been struggling with this question for awhile now, and I haven't reached a conclusion. I'm not typically a UI programmer, so forgive the noobishness. I'm writing a typical application with a UI layer (WPF) and a business layer. I want to post status messages to the UI from the business layer (perhaps deep within the business layer), but I don't want the business layer to have any knowledge of the UI. Is there a generally accepted pattern for this? I was thinking to have a message queue of some sort to which the business layer posts status messages, and have the view model of the UI subscribe to that queue and intercept messages from the queue and route them to the UI. Is that a good approach? Is there somewhere else I should start? Thank you.

  • c++/cli pass (managed) delegate to unmanaged code

    - by Ron Klein
    How do I pass a function pointer from managed C++ (C++/CLI) to an unmanaged method? I read a few articles, like this one from MSDN, but it describes two different assemblies, while I want only one. Here is my code: 1) Header (MyInterop.ManagedCppLib.h): #pragma once using namespace System; namespace MyInterop { namespace ManagedCppLib { public ref class MyManagedClass { public: void DoSomething(); }; }} 2) CPP Code (MyInterop.ManagedCppLib.cpp) #include "stdafx.h" #include "MyInterop.ManagedCppLib.h" #pragma unmanaged void UnmanagedMethod(int a, int b, void (*sum)(const int)) { int result = a + b; sum(result); } #pragma managed void MyInterop::ManagedCppLib::MyManagedClass::DoSomething() { System::Console::WriteLine("hello from managed C++"); UnmanagedMethod(3, 7, /* ANY IDEA??? */); } I tried creating my managed delegate and then I tried to use Marshal::GetFunctionPointerForDelegate method, but I couldn't compile.

  • What is Test Driven Development? Does it require to have initial designs?

    - by Nirajan Singh
    Hello Everybody, I am very new to TDD, not yet started using it. But i know that we have to write test first and then actual code to pass the test and refactor it till good design. My concern over TDD is that where does it fit in our SDLC. Suppose i get a requirement of making order processing system. Now, without having any model & design of this system, how can i start writing test. Shouldn't we require to define the entities & its attribute to proceed. If not, is it possible to develop big system without any design. I am really very confused over it. Can anyone help me to start TDD. Thanks in advance.

  • Rails - Posting a Boolean (true or False) and updating the DB in the controller

    - by AnApprentice
    Hello, in my Rails 3 App, I'm posting with jQuery the following: http://0.0.0.0:3000/topics/read_updater?&topic_id=101&read=true In my controller: def read_updater current_user.topics.where(:topic_id => params[:topic_id]).update_all(:read => params[:read]) render :json => {:status => 'success' } end params[:conversation_id] works great, but params[:read] is inserting empty values in the DB, even though jQuery is posting either a true or false. Ideas? I want rails to update the DB with either true or false. Thanks

  • Encrypting password in compiled C or C++ code

    - by Daniel
    Hello!, I know how to compile C and C++ Source files using GCC and CC in the terminal, however i would like to know if its safe to include passwords in these files, once compiled. For example.. i check user input for a certain password e.g 123, but it appears compiled C/C++ programs is possible to be decompiled. Is there anyway to compile a C/C++ source file, while keeping the source completely hidden.. If not, could anyone provide a small example of encrypting the input, then checking against the password e.g: (SHA1, MD5)

  • Is there a way to attach Ruby Net::HTTP request to a specific IP address / network interface?

    - by Dan Sosedoff
    Hello, Im looking a way to use different IP addresses for each GET request with standard Net::HTTP library. Server has 5 ip addresses and assuming that some API`s are blocking access when request limit per IP is reached. So, only way to do it - use another server. I cant find anything about it in ruby docs. For example, curl allows you to attach it to specific ip address (in PHP): $req = curl_init($url) curl_setopt($req, CURLOPT_INTERFACE, 'ip.address.goes.here'; $result = curl_exec($req); Is there any way to do it with Net::HTTP library? As alternative - CURB (ruby curl binding). But it will be the latest thing i`ll try. Suggestions / Ideas?
