  • In node.js slow readable stream attached to a faster pushing message queue eats up memory

    - by Vishal
    In my node.js program I have a response stream attached to a message queue (zeromq) delivering data at a very high rate. Due to slow network connection the response stream and its underlying implementation is unable to consume data at that pace thus occupying a lot of memory. Do you have any suggestion to solve this problem. For reference please see the code snippet below: zmq.on("message", function(data) { res.write(data); // End response on some event });

  • gzip several files and pipe them into one input

    - by Daniel
    I have this program that takes one argument for the source file and then it parse it. I have several files gzipped that I would like to parse, but since it only takes one input, I'm wondering if there is a way to create one huge file using gzip and then pipe it into the only one input.

  • How can I add imports to an "eval"ed piece of clojure code?

    - by Zubair
    I would like to evaluate some clojure code entered by users interactively, and I would like to "use" certain namespaces and "import" certain Java classes as well. I end up running the code using: (defn execute-command [string-command] let [ code-with-context (add-code-context string-command) result (eval(read-string code-with-context)) ] result ) My question is how can I program "add-code-context" to add the required context to the code in "string-command"?

  • Adding to a bit array

    - by Martin
    In my program, I am using BitArrays to represent 160 bit numbers. I want to be able to add, subtract, increment and decrement these numbers, what is the algorithm for doing this? At the moment I'm not interested in multiplication and division, but I might be in the future so bonus points for that. I'm implementing in C#, but pseudocode is fine if you're not familiar with the language

  • Nowaday C++ projects for Windows

    - by Andrew Florko
    Please, describe nowadays projects you took part in where C++ platform was preferred to .net where .net runtime could be installed. Some of my friends works in SCADA area. They have to program microcontrollers with Linux Embedded and so on. So my friends have nearly no choice in programming tools. But when you had, why did you prefer C++ ?

  • How can we detect a touch of a sprite?

    - by srikanth rongali
    I have two sprites in my app. Both should have touches enabled and both touches are independent of one another. And if I touch the screen (not on sprites) it should have different touches. My problem is all three sprite1, sprite2, remaining screen should have independent touches. But my program is taking all the touches as same. How can I make them as what I needed ? Thank You.

  • How can I test a windows dll to determine if it is 32bit or 64bit?

    - by morechilli
    I'd like to write a test script or program that asserts that all dlls in a given directory are of a particular build type. I would use this as a sanity check at the end of a build process on an sdk to make sure that the 64bit version hasn't somehow got some 32bit dlls in it and vice versa. Is there an easy way to look at a dll file and determine its type? The solution should work on both xp32 and xp64.

  • Send a variable on the heap to another thread

    - by user1201889
    I have a strange problem in C++. An address of a Boolean gets "destroyed" but it doesn't get touched. I know that there are beater way's to accomplish what I try to do, but I want to know what I do wrong. I have a main class; this main class contains a vector of another class. There is a strange problem when a new instance gets created of this object. This is how my code works: There will start a thread when the constructor gets called of the “2nd”object. This thread gets as Parameter a struct. This is the struct: struct KeyPressData { vector<bool> *AutoPressStatus; vector<int> *AutoPressTime; bool * Destroy; bool * Ready; }; The struct gets filled in the constructor: MultiBoxClient::MultiBoxClient() { //init data DestroyThread = new bool; ReadyThread = new bool; AutoThreadData = new KeyPressData; //Reseting data *DestroyThread = false; *ReadyThread = false; //KeyPressData configurating AutoThreadData->AutoPressStatus = &AutoPressStatus; AutoThreadData->AutoPressTime = &AutoPressTime; AutoThreadData->Destroy = DestroyThread; AutoThreadData->Ready = ReadyThread; //Start the keypress thread CreateThread(NULL,NULL,(LPTHREAD_START_ROUTINE)AutoKeyThread,AutoThreadData,NULL,NULL); } As long as the constructor is running will the program run fine. But when the constructor closes the address of the “AutoThreadData-Destroy” will get corrupted. The program will crash when I call the value of the pointer. void WINAPI AutoKeyThread(void * ThreadData) { KeyPressData * AutoThreadData = (KeyPressData*)ThreadData; while(true) { if(*AutoThreadData->Destroy == true) //CRASH { *AutoThreadData->Ready = true; return; } Sleep(100); } } What did I test: I logged the address of the AutoThreadData and the AutoThreadData-Destroy when the constrcutor is running and clossed; the AutoThreadData address is equal to AutoThreadData when the constructor is closed. So there is no problem here. The address of AutoThreadData-Destroy gets destroyed when the constructor is closed. But how can this happen? The Boolean is on the heap and the KeyPressData struct (AutoThreadData) is on the heap. Destroy before: 00A85328 Destroy after: FEEEFEEE Can someone maby explain why this crash? I know that I can send a pointer to my class to the thread. But I want to know what goes wrong here. That way I can learn from my mistakes. Could someone help me with this problem? Thanks!

  • variable scope when adding a value to a vector in class constructor

    - by TheFuzz
    I have a level class and a Enemy_control class that is based off an vector that takes in Enemys as values. in my level constructor I have: Enemy tmp( 1200 ); enemys.Add_enemy( tmp ); // this adds tmp to the vector in Enemy_control enemys being a variable of type Enemy_control. My program crashes after these statements complaining about some destructor problem in level and enemy_control and enemy. Any ideas?

  • System loops using non-integers?

    - by mary
    I wrote a .sh file to compile and run a few programs for a homework assignment. I have a "for" loop in the script, but it won't work unless I use only integers: #!/bin/bash for (( i=10; i<=100000; i+=100)) do ./hw3_2_2 $i done The variable $i is an input for the program hw3_2_2, and I have non-integer values I'd like to use. How could I loop through running the code with a list of decimal numbers?

    Hi, When I use this to write to my app.config file: Configuration config =ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None); config.AppSettings.Settings["Wachtwoord"].Value = "Test"; config.Save(); ConfigurationManager.RefreshSection("appSettings"); I can read it again. But when i close and restart the program, the value of "Wachtwoord" has changed again to the old value. Does anybody how I could fix this? Thanks

  • Swing: does DefaultBoundedRangeModel coalesce multiple events?

    - by Jason S
    I have a JProgressBar displaying a BoundedRangeModel which is extremely fine grained and I was concerned that updating it too often would slow down my computer. So I wrote a quick test program (see below) which has a 10Hz timer but each timer tick makes 10,000 calls to microtick() which in turn increments the BoundedRangeModel. Yet it seems to play nicely with a JProgressBar; my CPU is not working hard to run the program. How does JProgressBar or DefaultBoundedRangeModel do this? They seem to be smart about how much work it does to update the JProgressBar, so that as a user I don't have to worry about updating the BoundedRangeModel's value. package com.example.test.gui; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import javax.swing.BoundedRangeModel; import javax.swing.DefaultBoundedRangeModel; import javax.swing.JFrame; import javax.swing.JPanel; import javax.swing.JProgressBar; import javax.swing.Timer; public class BoundedRangeModelTest1 extends JFrame { final private BoundedRangeModel brm = new DefaultBoundedRangeModel(); final private Timer timer = new Timer(100, new ActionListener() { @Override public void actionPerformed(ActionEvent arg0) { tick(); } }); public BoundedRangeModelTest1(String title) { super(title); JPanel p = new JPanel(); p.add(new JProgressBar(this.brm)); getContentPane().add(p); this.brm.setMaximum(1000000); this.brm.setMinimum(0); this.brm.setValue(0); } protected void tick() { for (int i = 0; i < 10000; ++i) { microtick(); } } private void microtick() { this.brm.setValue(this.brm.getValue()+1); } public void start() { this.timer.start(); } static public void main(String[] args) { BoundedRangeModelTest1 f = new BoundedRangeModelTest1("BoundedRangeModelTest1"); f.pack(); f.setVisible(true); f.setDefaultCloseOperation(EXIT_ON_CLOSE); f.start(); } }

  • Thin down jQuery

    - by Taylor Satula
    Hi, I have been optimizing my website but the one problem that stands in my way is all the jQuery functions that I do not use. The only ones that I use are for a smooth page scroller. It just seems like such a waste of download time. My question is: Is there any script or program that will remove the jQuery code that I do not need and leave the 1 or 2 functions that I do need.

  • No more memory available in Mathematica, Fit the parameters of system of differential equation

    - by user1058051
    I encountered a memory problem in Mathematica, when I tried to process my experimental data. It's a system of two differential equations and I need to find most suitable parameters. Unfortunately I am not a Pro in Mathematica, so the program used a lot of memory, when the parameter epsilon is more than 0.4. When it less than 0.4, the program work properly. The command 'historylength = 0' and attempts to reduce the Accuracy Goal and WorkingPrecision didn`t help. I can't use ' clear Cache ', because there isnt a circle. I'm trying to understand what mistakes I made, and how I may limit the memory usage. I have already bought extra-RAM, now its 4GB, and now I haven't free memory-slots in motherboard Remove["Global`*"]; T=13200; L = 0.085; e = 0.41; v = 0.000557197; q = 0.1618; C0 = 0.0256; R = 0.00075; data = {{L,600,0.141124587},{L,1200,0.254134509},{L,1800,0.342888644}, {L,2400,0.424476295},{L,3600,0.562844542},{L,4800,0.657111356}, {L,6000,0.75137817},{L,7200,0.815876516},{L,8430,0.879823594}, {L,9000,0.900771775},{L,13200,1}}; model[(De_)?NumberQ, (Kf_)?NumberQ, (Y_)?NumberQ] := model[De, Kf, Y] = yeld /.Last[Last[ NDSolve[{ v (Ci^(1,0))[z,t]+(Ci^(0,1))[z,t]== -((3 (1-e) Kf (Ci[z,t]-C0))/ (R e (1-(R Kf (1-R/r[z,t]))/De))), (r^(0,1))[z,t]== (R^2 Kf (Ci[z,t]-C0))/ (q r[z,t]^2 (1-(R Kf (1-R/r[z,t]))/De)), (yeld^(0,1))[z,t]== Y*(v e Ci[z,t])/(L q (1-e)), r[z,0]==R, Ci[z,0]==0, Ci[0,t]==0, yeld[z,0]==0}, {r[z,t],Ci[z,t],yeld},{z,0,L},{t,0,T}]]] fit = FindFit[data, {model[De, Kf, Y][z, t], {Y > 0.97, Y < 1.03, Kf > 10^-6, Kf < 10^-4, De > 10^-13, De < 10^-9}}, {{De,7*10^-13}, {Kf, 10^-5}, {Y, 1}}, {z, t}, Method -> NMinimize] data = {{600,0.141124587},{1200,0.254134509},{1800,0.342888644}, {2400,0.424476295},{3600,0.562844542},{4800,0.657111356}, {6000,0.75137817},{7200,0.815876516},{8430,0.879823594}, {9000,0.900771775},{13200,1}}; YYY = model[ De /. fit[[1]], Kf /. fit[[2]], Y /. fit[[3]]]; Show[Plot[Evaluate[YYY[L,t]],{t,0,T},PlotRange->All], ListPlot[data,PlotStyle->Directive[PointSize[Medium],Red]]] the link on the .nb file http://www.4shared.com/folder/249TSjlz/_online.html
