  • Why does Clojure hang after hacing performed my calculations?

    - by Thomas
    Hi all, I'm experimenting with filtering through elements in parallel. For each element, I need to perform a distance calculation to see if it is close enough to a target point. Never mind that data structures already exist for doing this, I'm just doing initial experiments for now. Anyway, I wanted to run some very basic experiments where I generate random vectors and filter them. Here's my implementation that does all of this (defn pfilter [pred coll] (map second (filter first (pmap (fn [item] [(pred item) item]) coll)))) (defn random-n-vector [n] (take n (repeatedly rand))) (defn distance [u v] (Math/sqrt (reduce + (map #(Math/pow (- %1 %2) 2) u v)))) (defn -main [& args] (let [[n-str vectors-str threshold-str] args n (Integer/parseInt n-str) vectors (Integer/parseInt vectors-str) threshold (Double/parseDouble threshold-str) random-vector (partial random-n-vector n) u (random-vector)] (time (println n vectors (count (pfilter (fn [v] (< (distance u v) threshold)) (take vectors (repeatedly random-vector)))))))) The code executes and returns what I expect, that is the parameter n (length of vectors), vectors (the number of vectors) and the number of vectors that are closer than a threshold to the target vector. What I don't understand is why the programs hangs for an additional minute before terminating. Here is the output of a run which demonstrates the error $ time lein run 10 100000 1.0 [null] 10 100000 12283 [null] "Elapsed time: 3300.856 msecs" real 1m6.336s user 0m7.204s sys 0m1.495s Any comments on how to filter in parallel in general are also more than welcome, as I haven't yet confirmed that pfilter actually works.

  • Form loop db insertion + javascript altering

    - by MrStatic
    I basically need to check if there is an easier way to do this before I rewrite all the code. I have a fairly large form that I have each input named with []'s on the end so I can loop through via php for easy insertion. <input type="hidden" name="currentdate[]" value="<?php echo date('mdY'); ?>"> <td><input style="width: 50px" type="text" name="jackname[]" /></td> <td><input style="width: 20px" type="text" name="jackkey[]" /></td> <td><input style="width: 50px" type="text" name="jackbeg[]" /></td> <td><input style="width: 50px" type="text" name="jackend[]" /></td> <td><input style="width: 50px" type="text" name="jackbegveh" /></td> <td><input style="width: 50px" type="text" name="jackbegmon[]" /></td> <td><input style="width: 50px" type="text" name="jackendveh" /></td> <td><input style="width: 50px" type="text" name="jackendmon[]" /></td> <td><input style="width: 50px" type="text" name="jacktx" disabled /></td> There are quite a few more fields but you get the idea. I then use foreach ($_POST['jackname'] as $row=>$name) { $jackname = $name; $date = $_POST['currentdate'][$row]; $jackkey = $_POST['jackkey'][$row]; $jackbeg = $_POST['jackbeg'][$row]; $jackend = $_POST['jackend'][$row]; $jackbegveh = $_POST['jackbegveh'][$row]; $jackbegmon = $_POST['jackbegmon'][$row]; $jackendveh = $_POST['jackendveh'][$row]; $jackendmon = $_POST['jackendmon'][$row]; $jacktx = $_POST['jacktx'][$row]; if ($jacktx == '') { $jacktx = '0'; } if (empty($jackkey)) { echo 'Skipped empty! <br />'; } else { mysql_query("INSERT INTO `ticket_counts_jackson` VALUES('', '" . $date . "', '" . $jackname . "', '" . $jackkey . "', '" . $jackbeg . "', '" . $jackend . "', '" . $jackbegveh . "', '" . $jackbegmon . "', '" . $jackendveh . "', '" . $jackendmon . "', '" . $jacktx . "')", $mysql_link) or die(mysql_error()); echo 'Added the info the db! <br />'; } } I use the above to loop through the form and add it to the database. Now for my main question. I also want to add in some javascript to do a little math. Basically ($jackendveh - $jackbegveh) - ($jackendmon - $jackbegmon) and have that displayed in jacktx. Currently the only way I know of adding in the math calculations is to rename each input to a unique name and then rewrite my insert from 1 insert to 8 inserts.

  • How exactly do MbUnit's [Parallelizable] and DegreeOfParallelism work?

    - by BenA
    I thought I understood how MbUnit's parallel test execution worked, but the behaviour I'm seeing differs sufficiently much from my expectation that I suspect I'm missing something! I have a set of UI tests that I wish to run concurrently. All of the tests are in the same assembly, split across three different namespaces. All of the tests are completely independent of one another, so I'd like all of them to be eligible for parallel execution. To that end, I put the following in the AssemblyInfo.cs: [assembly: DegreeOfParallelism(8)] [assembly: Parallelizable(TestScope.All)] My understanding was that this combination of assembly attributes should cause all of the tests to be considered [Parallelizable], and that the test runner should use 8 threads during execution. My individual tests are marked with the [Test] attribute, and nothing else. None of them are data-driven. However, what I actually see is at most 5-6 threads being used, meaning that my test runs are taking longer than they should be. Am I missing something? Do I need to do anything else to ensure that all of my 8 threads are being used by the runner? N.B. The behaviour is the same irrespective of which runner I use. The GUI, command line and TD.Net runners all behave the same as described above, again leading me to think I've missed something. EDIT: As pointed out in the comments, I'm running v3.1 of MbUnit (update 2 build 397). The documentation suggests that the assembly level [parallelizable] attribute is available, but it does also seem to reference v3.2 of the framework despite that not yet being available. EDIT 2: To further clarify, the structure of my assembly is as follows: assembly - namespace - fixture - tests (each carrying only the [Test] attribute) - fixture - tests (each carrying only the [Test] attribute) - namespace - fixture - tests (each carrying only the [Test] attribute) - fixture - tests (each carrying only the [Test] attribute) - namespace - fixture - tests (each carrying only the [Test] attribute) - fixture - tests (each carrying only the [Test] attribute)

  • [C++][OpenMP] Proper use of "atomic directive" to lock STL container

    - by conradlee
    I have a large number of sets of integers, which I have, in turn, put into a vector of pointers. I need to be able to update these sets of integers in parallel without causing a race condition. More specifically. I am using OpenMP's "parallel for" construct. For dealing with shared resources, OpenMP offers a handy "atomic directive," which allows one to avoid a race condition on a specific piece of memory without using locks. It would be convenient if I could use the "atomic directive" to prevent simultaneous updating to my integer sets, however, I'm not sure whether this is possible. Basically, I want to know whether the following code could lead to a race condition vector< set<int>* > membershipDirectory(numSets, new set<int>); #pragma omp for schedule(guided,expandChunksize) for(int i=0; i<100; i++) { set<int>* sp = membershipDirectory[5]; #pragma omp atomic sp->insert(45); } (Apologies for any syntax errors in the code---I hope you get the point) I have seen a similar example of this for incrementing an integer, but I'm not sure whether it works when working with a pointer to a container as in my case.

    Thank you all in advance. I've got some great answers to my sometimes stupid questions, so thank you again. I'm trying to parse a SOAP response using PHP, Xpath (namespaces) and SimpleXML.

  • RPG Game loop and class structure (cocos2D for iPhone)

    - by mac_55
    I'm looking to make an RPG with Cocos2D on the iPhone. I've done a fair bit of research, and I really like the model Cocos2D uses for scenes. I can instantiate a scene, set up my characters etc. and it all works really nicely... what I have problems with is structuring a game loop and separating the code from the scenes. For example, where do I put my code that will maintain the state of the game across multiple scenes? and do I put the code for events that get fired in a scene in that scene's class? or do I have some other class that separates the init code from the logic? Also, I've read a lot of tutorials that mention changing scenes, but I've read none that talk about updating a scene - taking input from the user and updating the display based on that. Does that happen in the scene object, or in a separate display engine type class. Thanks in advance!

  • DNN redirect Loop

After I copied the site and changed the webconfig to point to the new site and changed the alias in the database I am getting this error. This webpage has a redirect loop. The webpage at http://xxx.us/xxx/default.aspx has resulted in too many redirects. Clearing your cookies for this site or allowing third-party cookies may fix the problem. If not, it is possibly a server configuration issue and not a problem with your computer.

    I have a dictionary d (and a seperate sorted list of keys, keys). I wanted the loop to only process entries where the value is False - so i tried the following: for key in keys and not d[key]: #do foo I suppose my understanding of python sytax is not what i thought it was - because the assignment doesnt suppose to have happened above, and a i get an instanciation error. The below works of course, but I'd really like to be able to use something like the code above.. possible? for key in keys: if d[key]: continue #foo time! Thanks!

  • WordPress - Each page of paged posts all show same posts

    - by j-man86
    I set up a pagination function for my wordpress blog. When clicking to the next page, the URL is correct: "/page/1", "/page/2", "/page/3" etc, but the actual posts don't change from page to page (page 2 and page 3 still display the first page of posts).

  • Get stacktrace from stuck python process

    - by piquadrat
    I have to run a legacy Zope2 website and have some grievance with it. The biggest issue is that, occasionally, it just locks up, running at 100% CPU load and not answering to requests anymore. While the problem isn't reproducible on a regular basis, one page containing 3 dynamic graphs triggers it sometimes, so I suspect some kind of race condition that leads to an endless loop or a stuck busywait. The problem is, I have not yet found a way to debug this thing. There's nothing in the Zope logs and nothing in the system logs. I tried the suggestions from this question to get a stacktrace, but the only signal that has any effect is SIGKILL. Is there another possibility to find out where exactly the process is when it gets stuck?

  • nested for loop

    - by Gary
    Hello, Just learning Python and trying to do a nested for loop. What I'd like to do in the end is place a bunch of email addresses in a file and have this script find the info, like the sending IP of mail ID. For now i'm testing it on my /var/log/auth.log file Here is my code so far: #!/usr/bin/python # this section puts emails from file(SpamEmail) in to a array(array) in_file = open("testFile", "r") array = in_file.readlines() in_file.close() # this section opens and reads the target file, in this case 'auth.log' log = open("/var/log/auth.log", "r") auth = log.readlines() for email in array: print "Searching for " +email, for line in auth: if line.find(email) > -1: about = line.split() print about[0], print Inside 'testfile' I have the word 'disconnect' cause I know it's in the auth.log file. It just doesn't find the word 'disconnect'. In the line of "if line.find(email) -1:" i can replace email and put "disconnect" the scripts finds it fine. Any idea? Thanks in advance. Gary

  • How to increment variable names/Is this a bad idea

    - by tom
    In Python, if I were to have a user input the number X, and then the program enters a for loop in which the user inputs X values, is there a way/is it a bad idea to have variable names automatically increment? ie: user inputs '6' value_1 = ... value_2 = ... value_3 = ... value_4 = ... value_5 = ... value_6 = ... Can I make variable names increment like that so that I can have the number of variables that the user inputs? Or should I be using a completely different method such as appending all the new values onto a list?

  • Alternative to Nested Loop For Comparison

    - by KGVT
    I'm currently writing a program that needs to compare each file in an ArrayList of variable size. Right now, the way I'm doing this is through a nested code loop: if(tempList.size()>1){ for(int i=0;i<=tempList.size()-1;i++) //Nested loops. I should feel dirty? for(int j=i+1;j<=tempList.size()-1;j++){ //*Gets sorted. System.out.println(checkBytes(tempList.get(i), tempList.get(j))); } } I've read a few differing opinions on the necessity of nested loops, and I was wondering if anyone had a more efficient alternative. At a glance, each comparison is going to need to be done, either way, so the performance should be fairly steady, but I'm moderately convinced there's a cleaner way to do this. Any pointers?

  • javascript date and loop check

    - by StealthRT
    Hey all, this is the code i have to check for a day thats equal to the list of days in the comma seperated list: for(var i = 0; i < daysHidden.length; i++){ if (daysHidden[i] == d.getDate()); { alert(daysHidden[i] + '=' + d.getDate()); } } the daysHidden = 1 (its the only thing in the list April 1st is already gone and todays the 2nd so 1 is the only one in the list) and d.getDate() has 1-30 (for april) When i run the code, however, it keeps looping through the if code when it should only loop once (when it finds that 1=1 However, i keep getting the alert box that says: 1=1 1=2 1=3 etc.... 1=30 So i do not know what i am doing incorrect? I already tried putting them as strings: if (daysHidden[i].ToString == d.getDate().ToString); But that doesnt seem to work.... Any help would be great :) David

  • MYSQL TRIGGER LOOP

    - by Lee
    Hey all I am going through the pain stacking process of sorting out someone else code. So I am decided to recreate a new database to sit alongside the old one then to use triggers to transfer data between both tables. Now I have an issue with a it looping IE A trigger on each table to update the other. Once one updates it should update the other but as both tables have triggers it just will loop which will cause an issue. Is their a way to stop this from happening ? Hope this makes sense and hope you can advise.

  • zsh: command not found: ls

    - by ABach
    I'm having a rather strange problem with zsh. When I start up my shell, everything - functions, environment vars, aliases, etc. - all work fine. I've created the following function and sourced it in zsh: clean() { for i in /tmp/* do echo $i done } Running clean in the terminal works as expected, in that it prints out all the files in /tmp/. Afterward, however, trying any command - for example, ls - produces this: zsh: command not found: ls I have several other functions that work just fine, which leads me to believe that somehow, that loop is causing the problem. At any rate, this is very frustrating and I would sincerely appreciate the community's eyes. Thanks!

  • Nasty deep nested loop in Rails

    - by CalebHC
    I have this nested loop that goes 4 levels deep to find all the image widgets and calculate their sizes. This seems really inefficient and nasty! I have thought of putting the organization_id in the widget model so I could just call something like organization.widgets.(named_scope), but I feel like that's a bad short cut. Is there a better way?

  • Loop through all subclasses in an Android view?

    - by Slapout
    I’m working on a game for Android. To help implement it, my idea is to create a subclass of a view. I would then insert several instances of this class as children of the main view. Each instance would handle detecting when it was pressed (via OnTouchListener). The problem I’m having now is how do I loop through all these sub-views so I can read their statuses and process them? (I.e. when they all reach a certain state something should happen). Or is there a better way to have several objects on the screen that respond to touch and whose status I can check?

  • Traditional loop versus Action delegate in C#

    - by emddudley
    After learning about the Action delegate in C# I've been looking for ways I can best use it in my code. I came up with this pattern: Action<string> DoSomething = (lSomething) => { // Do something }; DoSomething("somebody"); DoSomething("someone"); DoSomething("somewhere"); If I were to have used a traditional loop, it would look something like this: List<string> lSomeList = new List<string>(); lSomeList.Add("somebody"); lSomeList.Add("someone"); lSomeList.Add("somewhere"); foreach (string lSomething in lSomeList) { // Do something } Are there any appreciable differences between the two? To me they look equally easy to understand and maintain, but are there some other criteria I might use to distinguish when one might be preferred over the other?
