• mysql LAST_INSERT_ID() used with multiple records INSERT statement

  - by bogdan

  Hello, If i insert multiple records with a loop that executes a single record insert, the last insert id returned is, as expected, the last one... but if i do a multiple records insert statement: INSERT INTO people (name,age) VALUES('William',25),('Bart',15),('Mary',12); let's say the three above are the first records inserted in the table...after the insert statement i expected last insert id to return 3, but it returned 1...the first insert id for the statement in question... So can someone please confirm if this is the normal behavior of LAST_INSERT_ID() in the context of multiple records INSERT statements...so i can base my code on it thanks :)

• rcurl web scraping timeout exits program

  - by user1742368

  I am using a loop and rcurl scrape data from multiple pages which seems to work fine at certain times but fails when there is a timeout due to the server not responding. I am using a timeout=30 which traps the timeout error however the program stops after the timeout. i would like the progrm to continue to the next page when the timeout occurrs but cant figureout how to do this? url = getCurlHandle(cookiefile = "", verbose = TRUE) Here is the statement I am using that causes the timeout. I am happy to share the code if there is interest. webpage = getURLContent(url, followlocation=TRUE, curl = curl,.opts=list( verbose = TRUE, timeout=90, maxredirs = 2)) woodwardjj

• prevent using functions before initialization, constructors-like in C

  - by Hernán Eche

  This is the way I get to prevent funA,funB,funC, etc.. for being used before init #define INIT_KEY 0xC0DE //any number except 0, is ok static int initialized=0; int Init() { //many init task initialized=INIT_KEY; } int funA() { if (initialized!=INIT_KEY) return 1 //.. } int funB() { if (initialized!=INIT_KEY) return 1 //.. } int funC() { if (initialized!=INIT_KEY) return 1 //.. } The problem with this approach is that if some of those function is called within a loop so "if (initialized!=INIT_KEY)" is called again, and again, although it's not necessary. It's a good example of why constructors are useful haha, If it were an object I would be sure that when was created initialization was called, but in C, I don't know how to do it. Any other ideas are welcome!

• Divide numpy array

  - by BandGap

  Hi all I have some data represented in a 1300x1341 matrix. I would like to split this matrix in several pieces (e.g. 9) so that I can loop over and process them. The data needs to stay ordered in the sense that x[0,1] stays below (or above if you like) x[0,0] and besides x[1,1]. Just like if you had imaged the data, you could draw 2 vertical and 2 horizontal lines over the image to illustrate the 9 parts. If I use numpys reshape (eg. matrix.reshape(9,260,745) or any other combination of 9,260,745) it doesn't yield the required structure since the above mentioned ordering is lost... Did I misunderstand the reshape method or can it be done this way? What other pythonic/numpy way is there to do this?

• Import a number of csv files and replace NA by Zeros

  - by tao.hong

  I know how to do this individually. However, I have more than 1000 files. I decided to use a for loop. However, it seems like I did not find the correct way to evaluate my variables. Here is my code setwd('C:/data') filenames=dir() #find file names for (i in filenames){ adt = substr(x = i, start = 1, stop = nchar(i)-4) name=paste("data_", adt, sep="") assign(name, read.csv(i,header=T,sep=",")) #read each file and assign a variable name starting with data_ to it func=paste('name[is.na(name)] <- 0',sep="") # here is the place I have problem. R will not consider name is a parameter whose values change in each iteration eval((text=func)) }

• Turing's Craft exercise stumped me... seems too easy.

  - by Chris

  "Write a for loop that prints the integers 1 through 40, separated by spaces or new lines. You may use only one variable, count which has already been declared as an integer." So I use... for(count = 1; count <= 40; count++) { cout << " " << count; } but they are using stdio.h as the only header and cout is not recognized. It hints that the output format should be (" ",count), but I can't figure out what print function to use. stdio.h can use fprintf or fwrite, but I don't have enough parameters for either function. Any ideas?

• GetMessage with a timeout

  - by qdii

  I have an application which second thread calls GetMessage() in a loop. At some point the first thread realizes that the user wants to quit the application and notifies the second thread that he should terminate. As the first thread is stuck on GetMessage(), the program never quits. Is there a way to wait for messages with a timeout? I’m open to other ideas too. EDIT: (additional explanations) The second thread runs that snippet of code: while ( !m_quit && GetMessage( &msg, NULL, 0, 0 ) ) { TranslateMessage( &msg ); DispatchMessage( &msg ); } The first thread sets m_quit to true.

• Not able to kill bad kernel running on NVIDIA GPU

  - by arvindkgs

  Hi, I am in a real fix. Please help. Its urgent. I have a host process that spawns multiple host(CPU) threads. These threads in turn call the CUDA kernel. These CUDA kernels are written by external users. So it might be bad kernels that enter infinite loop. In order to overcome this I have put a time-out of 2 mins that will kill the corresponding CPU thread. Will killing the CPU thread also kill the kernel running on the GPU? As far as what I have tested it does'nt. How can I also kill all the threads currently running in the GPU? Thanks, Arvind

• Deleting an element from an array in perl

  - by Flamewires

  Hey I'm wondering how i can get this code to work, basically i want to keep the lines of $filename as long as they contain the $user in the path. Sry, perl noob. open STDERR, ">/dev/null"; $filename=`find -H /home | grep $file`; @filenames = split(/\n/, $filename); for $i (@filenames) { if ($i =~ m/$user/) { #keep results } else { delete $i; # does not work. } } $filename = join ("\n", @filenames); close STDERR; I know you can delete like delete $array[index] but I don't have an index with this kind of loop that I know of.

• C++: Why does space always terminate a string when read?

  - by Nullw0rm

  Using type std::string to accept a sentence, for practise (I haven't worked with strings in C++ much) I'm checking if a character is a vowel or not. I got this: for(i = 0; i <= analyse.length(); i++) { if(analyse[i] == 'a' || analyse[i] == 'e' [..etc..]) { ...vowels++; } else { ... ...consenents++; } This works fine if the string is all one word, but the second I add a space (IE: aeio aatest) it will only count the first block and count the space as a consenent, and quit reading the sentence (exiting the for loop or something). Does a space count as no character == null? Or some oddity with std::string?, It would be helpful to know why that is happening!

• Summation using Lambda C# 3.0

  - by Newbie

  I have a small thing. public int GetSum(List<int> x) { foreach (int i in x) sum += i; return sum; } where x is a List of integers defined as List<int> l = new List<int>(); l.Add(4); l.Add(2); l.Add(5); l.Add(8); l.Add(6); and has been passed as GetSum(l) Is it possible to rewrite the above foreach loop using a lambda? Reason: I started looking into the lambda stuffs since yesterday and is interested to learn .. however simple it may be. Thanks.

• c#, can you think of anymore optimization in this code?

  - by Sha Le

  Hi All: Look at the following code: StringBuilder row = TemplateManager.GetRow("xyz"); // no control over this method StringBuilder rows = new StringBuilder(); foreach(Record r in records) { StringBuilder thisRow = new StringBuilder(row.ToString()); thisRow.Replace("%firstName%", r.FirstName) .Replace("%lastName%", r.LastName) // all other replacement goes here .Replace("%LastModifiedDate%", r.LastModifiedDate); //finally append row to rows rows.Append(thisRow); } Currently 3 StringBuilders and row.ToString() is inside a loop. Is there any room for further optimization here? Thanks a bunch. :-)

• [PHP] - Lowering script memory usage in a "big" file creation

  - by Riccardo

  Hi there people, it looks like I'm facing a typical memory outage problem when using a PHP script. The script, originally developed by another person, serves as an XML sitemap creator, and on large websites uses quite a lot of memory. I thought that the problem was related due to an algorithm holding data in memory until the job was done, but digging into the code I have discovered that the script works in this way: open file in output (will contain XML sitemap entries) in the loop: ---- for each entry to be added in sitemap, do fwrite close file end Although there are no huge arrays or variables being kept in memory, this technique uses a lot of memory. I thought that maybe PHP was buffering under the hood the fwrites and "flushing" data at the end of the script, so I have modified the code to close and open the file every Nth record, but the memory usage is still the same.... I'm debugging the script on my computer and watching memory usage: while script execution runs, memory allocation grows. Is there a particular technique to instruct PHP to free unsed memory, to force flushing buffers if any? Thanks

• Interview Question: .Any() vs if (.Length > 0) for testing if a collection has elements

  - by Chris

  In a recent interview I was asked what the difference between .Any() and .Length > 0 was and why I would use either when testing to see if a collection had elements. This threw me a little as it seems a little obvious but feel I may be missing something. I suggested that you use .Length when you simply need to know that a collection has elements and .Any() when you wish to filter the results. Presumably .Any() takes a performance hit too as it has to do a loop / query internally.

• call inline function and pass in current item as the argument - Flex 3

  - by wcpro

  Im trying to create a loop of items like this... for each (var btn:Object in ViewButtonData) { // build element var box:HBox = new HBox(); box.styleName = "lefttab"; box.width = "100%"; box.addEventListener("rollOver", HoverTab(btn.id, 1)); box.addEventListener("rollOut", HoverTab(btn.id, 0)); // add element to list } I would like to pass in current HBox to the 'HoverTab' function. Is there a way to do that?

• C++ - Access array (in main) from methods outside main

  - by John Smith

  I have an array in my main class that holds objects that I need to print out for a menu listing. The array is declared and initialized in main. I need to, however, access the same array in a sub-menu function. If I copy the code (for loop that prints out the values) to the sub-menu, nothing is printed (presumably because it can't access the original array and has made a new, blank one). Is there any way (without making the array a global variable) that I can access the array in this sub-menu? Both the main and the sub-menu function are in the same file and the sub-menu is called from main. Maybe to put it more simply, can I use scope resolution to bring me up one 'level' in scope?

• RewriteRule and php download counter

  - by rcourtna

  (1) I have a site that serves up MP3 files: http://domain/files/1234567890.mp3 (2) I have a php script that tracks file download counts: http://domain/modules/download_counter.php?file=/files/1234567890.mp3 After download_counter.php records the download, it redirects to the original file: Header("Location: $FQDN_url"); (3) I'd like all my public links to be presented as the direct file urls from (1). I'm trying to use Apache to redirect the requests to download_counter.php: RewriteRule ^files/(.+\.mp3)$ /modules/download_counter.php?file=/files/$1 [L] I'm currently stuck on (3), as it results in a redirect loop, since download_counter.php simply redirects the request back to the original file (rather than streaming the file contents). I'm also motivated to use download_counter.php as is (without modifying it's redirect behaviour). This is because the script is part of a larger CMS module, and I'd like to avoid complicating my upgrade path. Perhaps there is no solution to my problem (other than modifying the download_counter script). WDYT?

• HttpHandler with Flash file upload question

  - by Projapati

  I have a flash file uploader that allows uploading multiple files in one shot. Now on one click how many times will the hanlder is supposed to be called? I am seeing that the ProcessRequest() of the HttpHandler is getting called for each of the files I upload. If I upload 5 files, then the Process request gets called 5 times. This seems odd. I would expect the handler to be called just once where I will loop the Can anyone confirm this behavior or I am missing something?

• A 'do' statement at the end of my perl script never runs

  - by Jeremy Petzold

  In my main script, I am doing some archive manipulation. Once I have completed that, I want to run a separate script to upload my archives to and FTP server. Separately, these scripts work well. I want to add the FTP script to the end of my archive script so I only need to worry about scheduling one script to run and I want to guarantee that the first script completes it work before the FTP script is called. After looking at all the different methods to call my FTP script, I settled on 'do', however, when my do statement is at the end of the script, it never runs. When I place it in my main foreach loop, it runs fine, but it runs multiple times which I want to avoid since the FTP script can handle having multiple archives to upload. Is there something I am missing? Why does it not run? Thanks

• LWJGL Circle program create's an oval-like shape

  - by N1ghtk1n9

  I'm trying to draw a circle in LWJGL, but when I draw I try to draw it, it makes a shape that's more like an oval rather than a circle. Also, when I change my circleVertexCount 350+, the shape like flips out. I'm really not sure how the code works that creates the vertices(I have taken Geometry and I know the basic trig ratios). I haven't really found that good of tutorials on creating circles. Here's my code: public class Circles { // Setup variables private int WIDTH = 800; private int HEIGHT = 600; private String title = "Circle"; private float fXOffset; private int vbo = 0; private int vao = 0; int circleVertexCount = 300; float[] vertexData = new float[(circleVertexCount + 1) * 4]; public Circles() { setupOpenGL(); setupQuad(); while (!Display.isCloseRequested()) { loop(); adjustVertexData(); Display.update(); Display.sync(60); } Display.destroy(); } public void setupOpenGL() { try { Display.setDisplayMode(new DisplayMode(WIDTH, HEIGHT)); Display.setTitle(title); Display.create(); } catch (LWJGLException e) { e.printStackTrace(); System.exit(-1); } glClearColor(0.0f, 0.0f, 0.0f, 0.0f); } public void setupQuad() { float r = 0.1f; float x; float y; float offSetX = 0f; float offSetY = 0f; double theta = 2.0 * Math.PI; vertexData[0] = (float) Math.sin(theta / circleVertexCount) * r + offSetX; vertexData[1] = (float) Math.cos(theta / circleVertexCount) * r + offSetY; for (int i = 2; i < 400; i += 2) { double angle = theta * i / circleVertexCount; x = (float) Math.cos(angle) * r; vertexData[i] = x + offSetX; } for (int i = 3; i < 404; i += 2) { double angle = Math.PI * 2 * i / circleVertexCount; y = (float) Math.sin(angle) * r; vertexData[i] = y + offSetY; } FloatBuffer vertexBuffer = BufferUtils.createFloatBuffer(vertexData.length); vertexBuffer.put(vertexData); vertexBuffer.flip(); vao = glGenVertexArrays(); glBindVertexArray(vao); vbo = glGenBuffers(); glBindBuffer(GL_ARRAY_BUFFER, vbo); glBufferData(GL_ARRAY_BUFFER,vertexBuffer, GL_STATIC_DRAW); glVertexAttribPointer(0, 2, GL_FLOAT, false, 0, 0); glBindBuffer(GL_ARRAY_BUFFER, 0); glBindVertexArray(0); } public void loop() { glClear(GL_COLOR_BUFFER_BIT); glBindVertexArray(vao); glEnableVertexAttribArray(0); glDrawArrays(GL_TRIANGLE_FAN, 0, vertexData.length / 2); glDisableVertexAttribArray(0); glBindVertexArray(0); } public static void main(String[] args) { new Circles(); } private void adjustVertexData() { float newData[] = new float[vertexData.length]; System.arraycopy(vertexData, 0, newData, 0, vertexData.length); if(Keyboard.isKeyDown(Keyboard.KEY_W)) { fXOffset += 0.05f; } else if(Keyboard.isKeyDown(Keyboard.KEY_S)) { fXOffset -= 0.05f; } for(int i = 0; i < vertexData.length; i += 2) { newData[i] += fXOffset; } FloatBuffer newDataBuffer = BufferUtils.createFloatBuffer(newData.length); newDataBuffer.put(newData); newDataBuffer.flip(); glBindBuffer(GL_ARRAY_BUFFER, vbo); glBufferSubData(GL_ARRAY_BUFFER, 0, newDataBuffer); glBindBuffer(GL_ARRAY_BUFFER, 0); } } 300 Vertex Count(This is my main problem) 400 Vertex Count - I removed this image, it's bugged out, should be a tiny sliver cut out from the right, like a secant 500 Vertex Count Each 100, it removes more and more of the circle, and so on.

• Sound plays multiple times at once

  - by Jr. Mathews

  I'm having trouble with sound in Flash. I may have went about coding the wrong way, because most of my codes are on frames. So, I have these two variables var outsideDay:Sound = new daysong(); var outsideNight:Sound = new nightsong(); And I want to play these songs on a specific frame. However, the sounds play sporadically, like 50 times at once. I think it's because I have other codes that link to the frames with a Enter_Frame function. How can I get the sounds to loop and not play multiple times at once?
