  • ActionScript MovieClip moves to the left, but not the right

    - by Defcon
    I have a stage with a movie clip with the instance name of "mc". Currently I have a code that is suppose to move the player left and right, and when the left or right key is released, the "mc" slides a little bit. The problem I'm having is that making the "mc" move to the left works, but the exact some code used for the right doesn't. All of this code is present on the Main Stage - Frame One //Variables var mcSpeed:Number = 0;//MC's Current Speed var mcJumping:Boolean = false;//if mc is Jumping var mcFalling:Boolean = false;//if mc is Falling var mcMoving:Boolean = false;//if mc is Moving var mcSliding:Boolean = false;//if mc is sliding var mcSlide:Number = 0;//Stored for use when creating slide var mcMaxSlide:Number = 1.6;//Max Distance the object will slide. //Player Move Function p1Move = new Object(); p1Move = function (dir:String, maxSpeed:Number) { if (dir == "left" && _root.mcSpeed<maxSpeed) { _root.mcSpeed += .2; _root.mc._x -= _root.mcSpeed; } else if (dir == "right" && _root.mcSpeed<maxSpeed) { _root.mcSpeed += .2; _root.mc._x += _root.mcSpeed; } else if (dir == "left" && speed>=maxSpeed) { _root.mc._x -= _root.mcSpeed; } else if (dir == "right" && _root.mcSpeed>=maxSpeed) { _root.mc._x += _root.mcSpeed; } } //onEnterFrame for MC mc.onEnterFrame = function():Void { if (Key.isDown(Key.LEFT)) { if (_root.mcMoving == false && _root.mcSliding == false) { _root.mcMoving = true; } else if (_root.mcMoving == true && _root.mcSliding == false) { _root.p1Move("left",5); } } else if (!Key.isDown(Key.LEFT)) { if (_root.mcMoving == true && _root.mcSliding == false) { _root.mcSliding = true; } else if (_root.mcMoving == true && _root.mcSliding == true && _root.mcSlide<_root.mcMaxSlide) { _root.mcSlide += .2; this._x -= .2; } else if (_root.mcMoving == true && _root.mcSliding == true && _root.mcSlide>=_root.mcMaxSlide) { _root.mcMoving = false; _root.mcSliding = false; _root.mcSlide = 0; _root.mcSpeed = 0; } } else if (Key.isDown(Key.RIGHT)) { if (_root.mcMoving == false && _root.mcSliding == false) { _root.mcMoving = true; } else if (_root.mcMoving == true && _root.mcSliding == false) { _root.p1Move("right",5); } } else if (!Key.isDown(Key.RIGHT)) { if (_root.mcMoving == true && _root.mcSliding == false) { _root.mcSliding = true; } else if (_root.mcMoving == true && _root.mcSliding == true && _root.mcSlide<_root.mcMaxSpeed) { _root.mcSlide += .2; this._x += .2; } else if (_root.mcMoving == true && _root.mcSliding == true && _root.mcSlide>=_root.mcMax) { _root.mcMoving = false; _root.mcSliding = false; _root.mcSlide = 0; _root.mcSpeed = 0; } } }; I just don't get why when you press the left arrow its works completely fine, but when you press the right arrow it doesn't respond. It is literally the same code.

  • Generating strongly biased radom numbers for tests

    - by nobody
    I want to run tests with randomized inputs and need to generate 'sensible' random numbers, that is, numbers that match good enough to pass the tested function's preconditions, but hopefully wreak havoc deeper inside its code. math.random() (I'm using Lua) produces uniformly distributed random numbers. Scaling these up will give far more big numbers than small numbers, and there will be very few integers. I would like to skew the random numbers (or generate new ones using the old function as a randomness source) in a way that strongly favors 'simple' numbers, but will still cover the whole range, I.e. extending up to positive/negative infinity (or ±1e309 for double). This means: numbers up to, say, ten should be most common, integers should be more common than fractions, numbers ending in 0.5 should be the most common fractions, followed by 0.25 and 0.75; then 0.125, and so on. A different description: Fix a base probability x such that probabilities will sum to one and define the probability of a number n as xk where k is the generation in which n is constructed as a surreal number1. That assigns x to 0, x2 to -1 and +1, x3 to -2, -1/2, +1/2 and +2, and so on. This gives a nice description of something close to what I want (it skews a bit too much), but is near-unusable for computing random numbers. The resulting distribution is nowhere continuous (it's fractal!), I'm not sure how to determine the base probability x (I think for infinite precision it would be zero), and computing numbers based on this by iteration is awfully slow (spending near-infinite time to construct large numbers). Does anyone know of a simple approximation that, given a uniformly distributed randomness source, produces random numbers very roughly distributed as described above? I would like to run thousands of randomized tests, quantity/speed is more important than quality. Still, better numbers mean less inputs get rejected. Lua has a JIT, so performance can't be reasonably predicted. Jumps based on randomness will break every prediction, and many calls to math.random() will be slow, too. This means a closed formula will be better than an iterative or recursive one. 1 Wikipedia has an article on surreal numbers, with a nice picture. A surreal number is a pair of two surreal numbers, i.e. x := {n|m}, and its value is the number in the middle of the pair, i.e. (for finite numbers) {n|m} = (n+m)/2 (as rational). If one side of the pair is empty, that's interpreted as increment (or decrement, if right is empty) by one. If both sides are empty, that's zero. Initially, there are no numbers, so the only number one can build is 0 := { | }. In generation two one can build numbers {0| } =: 1 and { |0} =: -1, in three we get {1| } =: 2, {|1} =: -2, {0|1} =: 1/2 and {-1|0} =: -1/2 (plus some more complex representations of known numbers, e.g. {-1|1} ? 0). Note that e.g. 1/3 is never generated by finite numbers because it is an infinite fraction – the same goes for floats, 1/3 is never represented exactly.

  • ActionScript 3 Cant see Movieclip

    - by user3697993
    When I play my game it does not show my _Player Movieclip, but it does collide with the ground which is very confusing. So I believe the movieclip is there but not showing the texture/Sprite. I think the problem is in "function Spawn" (First Function). public class PewdyBird extends MovieClip { //Player variables public var Up_Speed:int = 25; public var speed:Number = 0; public var _grav:Number = 0.5; public var isJump:Boolean = false; public var Score:int = 0; public var Player_Live:Boolean = true; public var _Player:Player = new Player(); //Other variables //Environment variables var Floor:int = 480; var Clock:Number = 0; var Clock_restart:Number = 0; var Clock_ON:Boolean = false; var Clock_max:int = 15; var Player_Stage:Boolean = true; private var _X:int; private var _Y:int; private var hit_ground:Boolean = false; private var width_BG:int = 479; //SPAWN function Spawn(e:Event){ _Player.x = 200; _Player.y = 200; stage.addChild(_Player); } //Keyboard Input private function KeyboardListener(e:KeyboardEvent){ if(e.keyCode == Keyboard.SPACE){ Clock = Clock_restart; Clock_ON = true; isJump = true; if(isJump){ _Player.gotoAndPlay("Fly"); speed = -Up_Speed; isJump = false; } } } //Mouse Input & Spawn Listener private function MouseListener(m:MouseEvent){ if(MouseEvent.CLICK){ Clock = Clock_restart; Clock_ON = true; isJump = true; if(isJump){ _Player.gotoAndPlay("Fly"); speed = -Up_Speed; isJump = false; } } } //Rotation Fly function Rot_Fly(){ if(Clock < Clock_max){ _Player.rotation = -15; }else if(Clock >= Clock_max){ if(_Player.rotation < 90){ _Player.rotation += 10; }else if(_Player.rotation >= 90){ _Player.rotation = 90; } } } //END //Update Function function enter_frame(e:Event):void{ Rot_Fly(); //Clock if(Clock_ON){ Clock++; }else if(Clock > Clock_max){ Clock = Clock_max; } //Fall Limits if(speed >= 20){ _Player.y += 20; return; _Player.gotoAndPlay("Fall"); } //Physics speed += _grav*3; _Player.y += speed; } //Hit Ground function Hit_Ground(e:Event){ if(_Player.hitTestObject(Ground1)){ _grav = 0; speed = 0; trace("HIT GROUND"); }else if(_Player.hitTestObject(Ground2)){ _grav = 0; speed = 0; trace("HIT GROUND"); }else if(_Player.hitTestObject(Ground1) == false){ _grav = 1; }else if(_Player.hitTestObject(Ground2) == false){ _grav = 1; } } //Background Slide (Left) private function Background_Move(e:Event):void{ Background1.x -= 1.5; Background2.x -= 1.5; Ground1.x -= 4; Ground2.x -= 4; if(Background1.x < -width_BG){ Background1.x = width_BG; } else if(Background2.x < -width_BG){ Background2.x = width_BG; } else if(Ground1.x < -width_BG){ Ground1.x = width_BG; } else if(Ground2.x < -width_BG){ Ground2.x = width_BG; } } } The eventListeners are in flash it self stage.addEventListener(Event.ENTER_FRAME, enter_frame); stage.addEventListener(Event.ENTER_FRAME, Hit_Ground); stage.addEventListener(KeyboardEvent.KEY_UP, KeyboardListener); stage.addEventListener(MouseEvent.CLICK, MouseListener); stage.addEventListener(Event.ENTER_FRAME, Background_Move); stage.addEventListener(Event.ADDED_TO_STAGE, Spawn);

  • bulls and cows game -- programming algorithm(python)

    - by IcyFlame
    This is a simulation of the game Cows and Bulls with three digit numbers I am trying to get the number of cows and bulls between two numbers. One of which is generated by the computer and the other is guessed by the user. I have parsed the two numbers I have so that now I have two lists with three elements each and each element is one of the digits in the number. So: 237 will give the list [2,3,7]. And I make sure that the relative indices are maintained.the general pattern is:(hundreds, tens, units). And these two lists are stored in the two lists: machine and person. ALGORITHM 1 So, I wrote the following code, The most intuitive algorithm: cows and bulls are initialized to 0 before the start of this loop. for x in person: if x in machine: if machine.index(x) == person.index(x): bulls += 1 print x,' in correct place' else: print x,' in wrong place' cows += 1 And I started testing this with different type of numbers guessed by the computer. Quite randomly, I decided on 277. And I guessed 447. Here, I got the first clue that this algorithm may not work. I got 1 cow and 0 bulls. Whereas I should have got 1 bull and 1 cow. This is a table of outputs with the first algorithm: Guess Output Expected Output 447 0 bull, 1 cow 1 bull, 1 cow 477 2 bulls, 0 cows 2 bulls, 0 cows 777 0 bulls, 3 cows 2 bulls, 0 cows So obviously this algorithm was not working when there are repeated digits in the number randomly selected by the computer. I tried to understand why these errors are taking place, But I could not. I have tried a lot but I just could not see any mistake in the algorithm(probably because I wrote it!) ALGORITHM 2 On thinking about this for a few days I tried this: cows and bulls are initialized to 0 before the start of this loop. for x in range(3): for y in range(3): if x == y and machine[x] == person[y]: bulls += 1 if not (x == y) and machine[x] == person[y]: cows += 1 I was more hopeful about this one. But when I tested this, this is what I got: Guess Output Expected Output 447 1 bull, 1 cow 1 bull, 1 cow 477 2 bulls, 2 cows 2 bulls, 0 cows 777 2 bulls, 4 cows 2 bulls, 0 cows The mistake I am making is quite clear here, I understood that the numbers were being counted again and again. i.e.: 277 versus 477 When you count for bulls then the 2 bulls come up and thats alright. But when you count for cows: the 7 in 277 at units place is matched with the 7 in 477 in tens place and thus a cow is generated. the 7 in 277 at tens place is matched with the 7 in 477 in units place and thus a cow is generated.' Here the matching is exactly right as I have written the code as per that. But this is not what I want. And I have no idea whatsoever on what to do after this. Furthermore... I would like to stress that both the algorithms work perfectly, if there are no repeated digits in the number selected by the computer. Please help me with this issue. P.S.: I have been thinking about this for over a week, But I could not post a question earlier as my account was blocked(from asking questions) because I asked a foolish question. And did not delete it even though I got 2 downvotes immediately after posting the question.

  • dynamic multiple instance of swfupload (firefox vs IE)

    We have this dynamic uploader which creates a new instance of swfupload. I'm a little bit confused with the outputs produced by firefox and ie.

  • Javascript For-Each Loop Syntax Help

    - by radrew
    Hey guys, I've got a complex block of PHP/Javascript that isn't functioning. I'm trying to manipulate a form that contains 4 dropdown select lists. Each dropdown is dependent upon what was selected in the one above it. I apologize for the huge amount of code, but I was hoping someone might be able to spot a syntax error or something else simple that I'm missing. The form in question is located in the right sidebar of the following site: http://www.buyautocovers.com $Manufacturer_array[] = array('id' => 'all', 'text' => $this->__('Choose Make')); $Model_array[] = array('id' = 'all', 'text' = $this-('Choose Model')); $Number_array[] = array('id' = 'all', 'text' = $this-('Choose Year')); $Body_array[] = array('id' = 'all', 'text' = $this-__('Choose Body Type')); $javascript = ' // var a = new Array(); var b = new Array(); var c = new Array(); var d = new Array();'; $M_a = array(); foreach ($rows as $r) { if (!isset($M_a [$r['manufacturer']])) $Manufacturer_array[] = array('id' = $r['manufacturer'], 'text' = $r['manufacturer']); $M_a [$r['manufacturer']][$r['model']][$r['number']][$r['body']] = 1; } $i = 0; foreach ($M_a as $k =$v){ $javascript .= 'a['.$i.']="'.$k.'";b['.$i.'];c['.$i.'];=new Array('; $ii = 0; $s = ''; foreach ($M_a[$k] as $kk =$vv){ $javascript .= ($ii != 0 ?

  • Questions related to writing your own file downloader using multiple threads java

    - by Shekhar
    Hello In my current company, i am doing a PoC on how we can write a file downloader utility. We have to use socket programming(TCP/IP) for downloading the files. One of the requirements of the client is that a file(which will be large in size) should be transfered in chunks for example if we have a file of 5Mb size then we can have 5 threads which transfer 1 Mb each. I have written a small application which downloads a file. You can download the eclipe project from http://www.fileflyer.com/view/QM1JSC0 A brief explanation of my classes FileSender.java This class provides the bytes of file. It has a method called sendBytesOfFile(long start,long end, long sequenceNo) which gives the number of bytes. import java.io.File; import java.io.IOException; import java.util.zip.CRC32; import org.apache.commons.io.FileUtils; public class FileSender { private static final String FILE_NAME = "C:\\shared\\test.pdf"; public ByteArrayWrapper sendBytesOfFile(long start,long end, long sequenceNo){ try { File file = new File(FILE_NAME); byte[] fileBytes = FileUtils.readFileToByteArray(file); System.out.println("Size of file is " +fileBytes.length); System.out.println(); System.out.println("Start "+start +" end "+end); byte[] bytes = getByteArray(fileBytes, start, end); ByteArrayWrapper wrapper = new ByteArrayWrapper(bytes, sequenceNo); return wrapper; } catch (IOException e) { throw new RuntimeException(e); } } private byte[] getByteArray(byte[] bytes, long start, long end){ long arrayLength = end-start; System.out.println("Start : "+start +" end : "+end + " Arraylength : "+arrayLength +" length of source array : "+bytes.length); byte[] arr = new byte[(int)arrayLength]; for(int i = (int)start, j =0; i < end;i++,j++){ arr[j] = bytes[i]; } return arr; } public static long fileSize(){ File file = new File(FILE_NAME); return file.length(); } } Second Class is FileReceiver.java - This class receives the file. Small Explanation what this file does This class finds the size of the file to be fetched from Sender Depending upon the size of the file it finds the start and end position till the bytes needs to be read. It starts n number of threads giving each thread start,end, sequence number and a list which all the threads share. Each thread reads the number of bytes and creates a ByteArrayWrapper. ByteArrayWrapper objects are added to the list Then i have while loop which basically make sure that all threads have done their work finally it sorts the list based on the sequence number. then the bytes are joined, and a complete byte array is formed which is converted to a file. Code of File Receiver package com.filedownloader; import java.io.File; import java.io.IOException; import java.util.ArrayList; import java.util.Collections; import java.util.Comparator; import java.util.List; import java.util.zip.CRC32; import org.apache.commons.io.FileUtils; public class FileReceiver { public static void main(String[] args) { FileReceiver receiver = new FileReceiver(); receiver.receiveFile(); } public void receiveFile(){ long startTime = System.currentTimeMillis(); long numberOfThreads = 10; long filesize = FileSender.fileSize(); System.out.println("File size received "+filesize); long start = filesize/numberOfThreads; List<ByteArrayWrapper> list = new ArrayList<ByteArrayWrapper>(); for(long threadCount =0; threadCount<numberOfThreads ;threadCount++){ FileDownloaderTask task = new FileDownloaderTask(threadCount*start,(threadCount+1)*start,threadCount,list); new Thread(task).start(); } while(list.size() != numberOfThreads){ // this is done so that all the threads should complete their work before processing further. //System.out.println("Waiting for threads to complete. List size "+list.size()); } if(list.size() == numberOfThreads){ System.out.println("All bytes received "+list); Collections.sort(list, new Comparator<ByteArrayWrapper>() { @Override public int compare(ByteArrayWrapper o1, ByteArrayWrapper o2) { long sequence1 = o1.getSequence(); long sequence2 = o2.getSequence(); if(sequence1 < sequence2){ return -1; }else if(sequence1 > sequence2){ return 1; } else{ return 0; } } }); byte[] totalBytes = list.get(0).getBytes(); byte[] firstArr = null; byte[] secondArr = null; for(int i = 1;i<list.size();i++){ firstArr = totalBytes; secondArr = list.get(i).getBytes(); totalBytes = concat(firstArr, secondArr); } System.out.println(totalBytes.length); convertToFile(totalBytes,"c:\\tmp\\test.pdf"); long endTime = System.currentTimeMillis(); System.out.println("Total time taken with "+numberOfThreads +" threads is "+(endTime-startTime)+" ms" ); } } private byte[] concat(byte[] A, byte[] B) { byte[] C= new byte[A.length+B.length]; System.arraycopy(A, 0, C, 0, A.length); System.arraycopy(B, 0, C, A.length, B.length); return C; } private void convertToFile(byte[] totalBytes,String name) { try { FileUtils.writeByteArrayToFile(new File(name), totalBytes); } catch (IOException e) { throw new RuntimeException(e); } } } Code of ByteArrayWrapper package com.filedownloader; import java.io.Serializable; public class ByteArrayWrapper implements Serializable{ private static final long serialVersionUID = 3499562855188457886L; private byte[] bytes; private long sequence; public ByteArrayWrapper(byte[] bytes, long sequenceNo) { this.bytes = bytes; this.sequence = sequenceNo; } public byte[] getBytes() { return bytes; } public long getSequence() { return sequence; } } Code of FileDownloaderTask import java.util.List; public class FileDownloaderTask implements Runnable { private List<ByteArrayWrapper> list; private long start; private long end; private long sequenceNo; public FileDownloaderTask(long start,long end,long sequenceNo,List<ByteArrayWrapper> list) { this.list = list; this.start = start; this.end = end; this.sequenceNo = sequenceNo; } @Override public void run() { ByteArrayWrapper wrapper = new FileSender().sendBytesOfFile(start, end, sequenceNo); list.add(wrapper); } } Questions related to this code 1) Does file downloading becomes fast when multiple threads is used? In this code i am not able to see the benefit. 2) How should i decide how many threads should i create ? 3) Are their any opensource libraries which does that 4) The file which file receiver receives is valid and not corrupted but checksum (i used FileUtils of common-io) does not match. Whats the problem? 5) This code gives out of memory when used with large file(above 100 Mb) i.e. because byte array which is created. How can i avoid? I know this is a very bad code but i have to write this in one day -:). Please suggest any other good way to do this? Thanks Shekhar

  • AS3 XML Slideshow Woes

    - by Chris
    Hello All, I am hoping someone out there can possibly shed some light on a couple issues I am having with an image slideshow I have been working on a simple slideshow for a project and everything was going great/as expected up until I created a function to hide the previous images before displaying the next. On the first pass through everything seems to run fine; once the slideshow starts over, the images don't show up, yet when it goes to load the following image, it plays the tween from the hide previous function which shows the image briefly before fading out. So essentially the display is blank, then the timer calls in the next slide and its a brief flash of an image fading out, and then blank again. Another issue I am having is the text that I am loading in from the XML does not seem to want to tween in or out as they are supposed to. Here is the code: import fl.transitions.Tween; import fl.transitions.easing.*; import fl.transitions.TweenEvent; import flash.display.BitmapData; import flash.display.Bitmap; import flash.display.Sprite;

Any help would really be appreciated, and I thank you all in advance.

  • Validating textboxes and checkboxes then add the values of those checkboxes

    - by TiTi Nguyen
    I am very new to Javascript. I am running to a problem and don't know how to solve it. Could you please help? Basically, I want to create some textboxes and checkboxes in a form. Then I have to validate those fields, and add the values of the checkboxes if they are selected. One of the textboxes asking for how many semesters attended, and 3 checkboxes with value of 100, 1000, and 750. Whichever checkbox is selected, it should multiply its value to the number of semesters attended. For example if the first two checkboxes are selected then totalCost = (100+1000)* semester. Here is my code: User Name: <label>User Address: <input type = "text" id ="address" size = "30"/></label> <br/><br/> <label> User E-mail address: <input type = "text" id ="email" size = "30"/></label> <br/><br/> <label> User Phone number: <input type = "text" id ="phone" size = "30"/></label> <br/><br/> <label> User area code: <input type = "text" id ="area" size = "30"/></label> <br/><br/> <label> User SSN: <input type = "text" id ="ssn" size = "30"/></label> <br/><br/> <label> User Birthday: <input type = "text" id ="birthday" size = "30"/></label> <br/><br/> <label> Number of semester attended: <input type = "text" id ="semester" size = "3"/></label> <br/><br/> <label><input type="checkbox" id="box_book" value="100"/>Books $100 per semester</label> <br/> <label><input type="checkbox" id="box_tuition" value="1000"/>Tuition $1000 per semester</label> <br/> <label><input type="checkbox" id="box_room" value="750"/>Room and Board $750 per semester</label> <br/> <input type="reset" id="reset"/> <input type="submit" id="submit" onclick="checking()"/> <p/> </form> function checking() { var name=document.forms["myForm"]["name"].value; var address=document.forms["myForm"]["address"].value; var email=document.forms["myForm"]["email"].value; var atpos=email.indexOf("@"); var dotpos=email.lastIndexOf("."); var phone=document.forms["myForm"]["phone"].value; var area=document.forms["myForm"]["area"].value; var ssn=document.forms["myForm"]["ssn"].value; var birth=document.forms["myForm"]["birthday"].value; var semester=document.forms["myForm"]["semester"].value; var boxBook = document.forms["myForm"]["box_book"].value; var boxTuition = document.forms["myForm"]["box_tuition"].value; var boxRoom = document.forms["myForm"]["box_room"].value; if (name==null || name=="") { alert("Please fill in your name."); return false; } if (address==null || address=="") { alert("Please fill in your address."); return false; } if (atpos<1 || dotpos<atpos+2 || dotpos+2>=email.length) { alert("The email (" + email + ") is not a valid e-mail address.

  • Why my shell program wont open the file got as argument in function "cat"

    I included the code below, sorry to bother you with so much code. Argument parsing is ok, i checked it out with watches. I've put some printfs to check out where the problem may be and it seems that it wont open the file cat receives as argument. i called from shell like "cat -b file" #include <stdio.h> #include <stdlib.h> #include <unistd.h> #include <string.h> #define TRUE 0 #define FALSE 1 void yes(int argc, char *argv[]); int cat(int argc, char *argv[]); //#include "cat.h" //#include "yes.h" //#include"tee.h" char buf[50],c[10], *p2,*p, *pch; int count; char *matrix[20]; void yes(int argc, char *argv[]) { int i; // if (argc >= 2 && *argv[1] == '-') // { //printf("ERROR!"); //} //if (argc == 1) // { while (1) if (puts("y") == EOF) { perror("yes"); exit(FALSE); } // } while (1) for (i = 1; i < argc; i++) if (fputs(argv[i], stdout) == EOF || putchar(i == argc - 1 ?

  • Custom language - FOR loop in a clojure interpeter?

    - by Mark
    I have a basic interpreter in clojure. Now i need to implement for (initialisation; finish-test; loop-update) { statements } Implement a similar for-loop for the interpreted language. The pattern will be: (for variable-declarations end-test loop-update do statement) The variable-declarations will set up initial values for variables.The end-test returns a boolean, and the loop will end if end-test returns false. The statement is interpreted followed by the loop-update for each pass of the loop. Examples of use are: (run ’(for ((i 0)) (< i 10) (set i (+ 1 i)) do (println i))) (run ’(for ((i 0) (j 0)) (< i 10) (seq (set i (+ 1 i)) (set j (+ j (* 2 i)))) do (println j))) inside my interpreter. I will attach my interpreter code I got so far. Any help is appreciated.

  • Oracle VM repository creation seems contradictory to its server pool?

    - by Michael
    I found something contradictory in Oracle VM. Clustered server pool creation in Oracle VM would format my FC LUN as ocfs2 , and start o2cb & ocfs2 services to build cluster environment. After that, when I wanted to create repository on the serverpool, unexpectedly, it told me that the physical disk I chose which is also my FC LUN, already contains a file system. What a contradictory! So what, delete the file system in serverpool? If so, why created it before?! OVM> list physicaldisk Command: list physicaldisk Status: Success Time: 2012-09-10 06:44:42.660 Data: id:0004fb00001800007765e62381895f61 name:OVM_HDS OVM> create serverpool clusterenable=true virtualip=10.84.21.123 physicaldisk=OVM_HDS name=ovmserverpool Serverpool creation took quite a long time since my FC LUN was big. When the creation completed, my FC LUN was created as ocfs2 and o2cb & ocfs2 services were started on my ovm servers successfully. But then repository creation indeed throws me a big surprise ... OVM> create repository serverpool=ovmserverpool physicaldisk=OVM_HDS name=ovmrepo Command: create repository serverpool=ovmserverpool physicaldisk=OVM_HDS name=ovmrepo Status: Failure Time: 2012-09-10 06:23:44.656 Error Msg: com.oracle.ovm.mgr.api.exception.RuleException: OVMRU_002026E Cannot use or delete physical disk: OVM_HDS, it already contains a file system: [Pool filesystem for ovmserverpool] Mon Sep 10 06:23:44 CST 2012 What should I do now? Delete the filesystem using dd command? That would destroy the serverpool, right? I'm really confused. My OVM Manager version is 3.1.1.399 which is the latest. Any tips are appreciated. Thanks.

  • alias gcc='gcc -fpermissive' or modifying ./configure script

    - by robo
    I am compiling quite big project from source. The compilation always ends with: error: invalid conversion from ‘const char*’ to ‘char*’ [-fpermissive] I have already compiled this project one year ago. So I know a solution to this. Actualy I found more solutions: Adding a typecast to appropriate line of cpp code (It went to endless number of changes in each file. So I found next solution.) Modifying a makefile to compile that file with -fpermissive option. (I had to modify a lot of lines in each makefile. So I find even better solution.) "g++" or "gcc" was stored in a variable so I added -fpermissive to these variables. This is the best solution I have. It is sufficient to add this option to each makefile once. Unfortunately this software has big number of subdirectories. So I need to modify more than 100 makefiles. It took me whole day one year ago. Is there a way how to do this faster. What about this? alias gcc='gcc -fpermissive' I am not familiar with aliases. But it should be easy to try this. Is the syntax correct? And is this one correct? alias g++='g++ -fpermissive' ? And do I need to export the alias somehow? Will the make program respect the alias? Should I maybe change ./configure script? Or the ./configure.in? Or other file?

  • How to boot Linux from a 16gb USB flash drive

    - by Chris Harris
    I'm trying to install Linux on a single partition of a USB flash drive that's larger than 4gb. The first place I went to is http://pendrivelinux.com. I can follow these instructions for installing Xubuntu 9.04 perfectly, which unfortunately break down when I try to scale it up beyond 4gb. There are several other tools to do this (unetbootin and usb-creator) which follow a very similar formula. I figured out that a big problem of mine was that all of these tools assume the USB drive is formatted in FAT32, which unfortunately cannot hold a single file larger than 4gb. This is unfortunate because I want to use just one partition, so that my persistance file, casper-rw, looks like one big partition to the OS once I've booted off of the USB drive. I then tried following a myriad of instructions involving formatting the drive as one large ext2 filesystem and using extlinux to create a single bootable ext2 file system. This doesn't work for me however, after about 20 attempts verifying and slightly tweaking the formula, I cannot seem to get a "good" bootable ext2 file system built. I'm not entirely sure what's going on, but it seems as though no matter how hard I try, I cannot get the ext2 file system to remain coherent after copying the Linux ISO contents over, copying the MBR, and executing extlinux to create the ext bootloader. Every time, after I follow these steps (in any order) and reboot, I get an unbootable USB drive. If I then mount the drive under Linux again, I see a mess of a file system (inodes have clearly been screwed up somewhere along the way). I suspected that the USB drive wasn't being fully flushed, so I tried using the "sync" and "unmount" commands before rebooting which didn't affect things at all. I guess I have several possible questions - but let's start with the obvious - is there something I'm missing to create a bootable ext2 USB flash drive that's large (e.g. 16gb)?

  • How to configure amavisd-new for only scanning on particular senders/servers?

    - by mailq
    I'd like to know how to configure amavisd-new to only scan for Spam on particular clients (IPs, CIDRs or hostnames) or alternatively sender's email domain. I know that it is possible to do it on a recipient's mail address but not on how to do it for the sender's mail address. It is even possible to do it on a recipient's IP address with policy banks. But my approach should be to be independent of recipient and only relay on the sender. What I want to accomplish is to only scan mails originating from Yahoo, Google, Hotmail and the other big senders. So it is easier to configure which senders should be observed than the ones that shouldn't. I known that it is easier to achieve on the MTA side, but that is not part of the question because I already go a solution on the MTA side. I want to do it on amavisd-new. And it doesn't help to know how to put senders on a whitelist, as this still means that the mail goes through all the scanning but then gets a high negative score. The mail shouldn't be scanned at all unless sent by the big players. So which parameters in amavisd-new is the right one to enable scanning for particular senders and only for these?

  • Performance of Virtual machines on very low end machines

    - by TheLQ
    I am managing a few cheap servers as my user base isn't large enough to get much more powerful servers. I also don't have the money lying around to invest in a server to prepare for the larger user base. So I'm stuck with the old hardware I have. I am toying with the idea of virtualizing all the current OS's with most likely VMware vSphere Hypervisor (AKA ESXi) Xen (ESXi has too strict of an HCL, and my hardware is too old). Big reasons for doing so: Ability to upgrade and scale hardware rapidly - This is most likely what I'll be doing as I distribute services, get a bigger server, centralize (electricity bills are horrible), distribute, get a bigger server, etc... Manually doing this by reinstalling the entire OS would be a big pain Safety from me - I've made many rookie mistakes, like doing lots of risky work on a vital production server. With a VM I can just backup the state, work on my machine, test, and revert if necessary. No worries, and no OS reinstallation Safety from other factors - As I scale servers might go down, and a backup VM can instantly be started. Various other reasons. However the limiting factor here is hardware. And I mean very depressing hardware. The current server's run off of a Pentium 3 and 4, and have 512 MB and 768 MB RAM respectively (RAM can be upgraded soon however). Is the Virtualization layer small enough to run itself and a Linux OS effectively? Will performance be acceptable (50% CPU overhead for every operation isn't acceptable)? Does it leave enough RAM for the Linux OS? Is this even feasible?

  • Migrating to Amazon AWS etc: What key statistics/questions should be analyzed and asked?

    - by cerd
    I searched SOverflow pretty extensively for something similar to this set of questions. BACKGROUND: We are a growing 'big(ish)' data chemical data company that are outgrowing our lab and our dedicated production workhorses. Make no mistake, we need to do some serious query optimization. Our data (It comes from a certain govt. agency so the schema and lack of indexing is atrocious). So yes, I know, AWS or EC2 is not a silver bullet in the face of spending time to maybe rework your queries/code entirely 'out of the box'. With that said I would appreciate any input on the following questions: We produce on CentOS and lab on Ubuntu LTS which I prefer especially with their growing cloud / AWS integration. If we are mysql centric, and our biggest problem is these big cartesian products that produce slow queries, should we roll out what we know after more optimization with respect to Ubuntu/mySQL with the added Amazon horsepower? Or is there some merit to the NoSQL and other technologies they offer? What are the key metrics I need to gather from apache and mysql other than like: Disk I/O operations, Data up/down avgs and trends and special high usage periods/scenarios? I've reviewed AWS/EC2 fine print, but want 2nd opinions. What other services aside from the basic web/database have proven valuable to you? I know nothing of Hadoop or many other technologies they offer, echoing my prev. question, do you sometimes find it worth it (Initially having it be a gamble aside from basic homework) to dive/break into a whole new environment and try to/or end up finding a way of more efficiently producing your data/site product? Anything I should watch out for in projecting costs, or any other general advice when working with AWS folks from anyone else where your company is very niche and very very technical (Scientifically - or anybody for that matter)? Thanks very much for your input - I think this thread could be valuable to others as well.

  • Change DPI setting in Windows 8.1 for the Logon Screen

    - by jmc302005
    How can the DPI setting be changed for the Logon Screen in Windows 8.1? Microsoft has added per-user DPI settings. But this means that there is no adjustable DPI setting for the Lock/Logon screen. You can change the DPI setting to be the same across all displays and this does affect the icons and font on the lock/logon screen. However, it does not affect any app/program that can run on the lock/logon screen. Ex. I use a 44" flat screen TV for my monitor on my desktop. Big enough for me to sit in my recliner and use my computer. I use the on-screen keyboard most of the time. (I don't want to keep a keyboard next to me.) The problem is that with the new DPI setup the on-screen keyboard takes up nearly half the screen, which is too big. I tried looking through the registry to see if I could find a setting for it. In the key HKEY_USERS\.DEFAULT\Control Panel\Desktop there is a string value named LogicalDPIOverride with a value of -1. I have a feeling this is where I can fix the issue. I tried changing the value to 0 and to 1 with no change in the result. Instead I noticed that after logging out and back in the -1 value was back in the registry. How can I change this default DPI? Can I use the LogPixels string that worked for DPI in Windows 7? Here are two Screen shots, one of the Lock Screen and one of the Logon Screen:

Not worried about installing new packages or building something from source, that's not a big issue, just want to get it working. Big plus if I can do it from command line.

  • How to compress .pdfs in word 2007?

    - by chobo2
    Hi I am trying to send my cover letter and resume away but apparently it is too big to send through craigs list(my computer says the total size is 500kb) as it has a 600kb limit(so small should be at least a meg). Hi there. You recently tried to email Some job Email, an anonymous craigslist address. However, your message was too big to be sent through our system. Craigslist has a 600KB limit on the messages we'll send. Please reduce the size of your mail and try again. Thanks for using craigslist. So when I convert my word 2007(.docx) files to pdf they become huge. Like they got from 32kb to 320kb. So is there a way I can either get around craigslist limits or compress my pdfs a bit to make it happy. I don't want to send zips and stuff since the person who gets it might not even know what to do. I rather not send .docx since not sure if will have office 2007 or the compatibility view installed and I rather just send it as pdf(as some place require it anyways to be in pdfs). Thanks

  • Why have trackballs almost disappeared? [closed]

    - by Gary M. Mugford
    One of the movement sensors in my Microsoft Trackball Explorer has failed and right now I am using a mouse. Ugggh! I'll got steal one of the various Logitech trackballs spread around the house, but they all have issues. The Trackman has a horrible placement for the scroll wheel. Others have marbles for the thumb rather than a big ball for the fingers and at least one trackball is working around here without having a scroll wheel at all! (The one at the dinner table, for when I dine alone). My question is, why have trackballs fallen into disfavour? Seems to me that trackballs are great for crowded desktops (you know, the one with keyboards, notes, pens and coffee cups), and for laptops with those hated overly-sensitive touchpads. But right now, it seems to be a choice between that Logitech Trackman and some Kensington models that lack scroll wheels. All I want is a nice big ball to manipulate with the fingers and two buttons on the thumb side with the scroil wheel between them. Placement of other buttons is completely optional. Is that asking too much?

  • Disk IO slow on ESXi, even slower on a VM (freeNAS + iSCSI)

    - by varesa
    I have a server with ESXi 5 and iSCSI attached network storage(4x1Tb Raid-Z on freenas 8.0.4). Those two machines are connected to each other with Gigabit ethernet. The raid-z volume is divided into three parts: two zvols, shared with iscsi, and one directly on top of zfs, shared with nfs and similar. I ssh'd into the freeNAS box, and did some testing on the disks. I used ddto test the third part of the disks (straight on top of ZFS). I copied a 4GB (2x the amount of RAM) block from /dev/zero to the disk, and the speed was 80MB/s. Other of the iSCSI shared zvols is a datastore for the ESXi. I did similar test with time dd .. there. Since the dd there did not give the speed, I divided the amount of data transfered by the time show by time. The result was around 30-40 MB/s. Thats about half of the speed from the freeNAS host! Then I tested the IO on a VM running on the same ESXi host. The VM was a light CentOS 6.0 machine, which was not really doing anything else at that time. There were no other VMs running on the server at the time, and the other two "parts" of the disk array were not used. A similar dd test gave me result of about 15-20 MB/s. That is again about half of the result on a lower level! Of course the is some overhead in raid-z - zfs - zvolume - iSCSI - VMFS - VM, but I don't expect it to be that big. I belive there must be something wrong in my system. I have heard about bad performance of freeNAS's iSCSI, is that it? I have not managed to get any other "big" SAN OS to run on the box (NexentaSTOR, openfiler). Can you see any obvious problems with my setup?
