  • implementing keepalives with Java

    - by Bilal
    Hi All, I am biulding a client-server application where I have to implement a keepalive mechanism in order to detect that the client has crashed or not. I have separate threads on both client and server side. the client thread sends a "ping" then sleeps for 3 seconds, while the server reads the BufferedInput Stream and checks whether ping is received, if so it makes the ping counter eqauls zero, else it increments the counter by +1, the server thread then sleeps for 3 seconds, if the ping counter reaches 3, it daclares the client as dead. The problem is that when the server reads the input stream, its a blocking call, and it blocks untill the next ping is received, irrespective of how delayed it is, so the server never detects a missed ping. any suggestions, so that I can read the current value of the stream and it doesn't block if there is nothing on the incoming stream. Thanks,

  • how can i substitute a NULL value for a 0 in an SQL Query result

    - by Name.IsNullOrEmpty
    SELECT EmployeeMaster.EmpNo, Sum(LeaveApplications.LeaveDaysTaken) AS LeaveDays FROM EmployeeMaster FULL OUTER JOIN LeaveApplications ON EmployeeMaster.id = LeaveApplications.EmployeeRecordID INNER JOIN LeaveMaster ON EmployeeMaster.id = LeaveMaster.EmpRecordID GRoup BY EmployeeMaster.EmpNo order by LeaveDays Desc with the above query, if an employee has no leave application record in table LeaveApplications, then their Sum(LeaveApplications.LeaveDaysTaken) AS LeaveDays column returns NULL. What i would like to do is place a value of 0 (Zero) instead of NULL. I want to do this because i have a calculated column in the same query whose formular depends on the LeaveDays returned and when LeaveDays is NULL, the formular some how fails. Is there away i can put 0 for NULL such that that i can get my desired result.

  • Cant free memory.

    - by atch
    In code: int a[3][4] = {1,2,3,4, 5,6,7,8, 9,10,11,12}; template<class T, int row, int col> void invert(T a[row][col]) { T* columns = new T[col]; T* const free_me = columns; for (int i = 0; i < col; ++i) { for (int j = 0; j < row; ++j) { *columns = a[j][i]; ++columns;//SOMETIMES VALUE IS 0 } } delete[] free_me;//I'M GETTING ERROR OF HEAP ABUSE IN THIS LINE } int main(int argc, char* argv[]) { invert<int,3,4>(a); } I've observed that while iterating, value of variable columns equals zero and I think thats the problem. Thanks for your help.

  • Versioned cloud-based social code snippet management

    - by Chapso
    It seems a lot to ask, but I'm looking for a cloud-based solution to managing code snippets. I am looking for: Tags User accounts (I want to be able to see all of my snippets on a single page) syntax highlighting versioning - myself or others should be able to edit my snippets to improve them\ straightforward UI with minimal advertising if any Does anyone know of a solution which meets these requirements? If not, would anyone be interested in something like this? As a software engineer, after step zero (does it already exist), I'm perfectly willing to go onto step 1 (would other people use it? If so, make it).

  • Masking a bit in C returning unexpected result

    - by Eamorr
    0x7F000000 is 0111 1111 0000 0000 0000 0000 0000 0000 in 32 bit binary. 0x01000058 is 0000 0001 0000 0000 0000 0000 0101 1000. When I AND the two numbers together I expect 0000 0001 0000 0000 0000 0000 0000 0000, but for some reason I get 0. Here is my code: #define MASK_binop 0x80000000 #define MASK_operation 0x7F000000 int instruction=atoi(line); if((MASK_binop & instruction)>0) printf("binop\n"); else if((MASK_operation & instruction)>0) printf("operation\n"); Each of the above comparisons keeps returning zero. Is it something to do with 32/64 bits? I'm using 64-bit compiler.

  • Can I optimize this at all?

    - by Moshe
    I'm working on an iOS app and I'm using the following code for one of my tables to return the number of rows in a particular section: return [[kSettings arrayForKey:@"views"] count]; Is there any other way to write that line of code so that it is more memory efficient? EDIT: kSettings = NSUserDefaults standardUserDefaults. Is there any way to rewrite my line of code so that whatever memory it occupies is released sooner than it is released now?

  • How to have game audio loop at a certain point

    - by Essential
    I have a storm in my game, and so I've made an ambient audio file which slowly grows into a storm and rain fades in, which then becomes a loopable storm audio file. Here is how I've done it: // Play intro clip and merge into main loop var introTime = stormIntro.length; AudioSource.PlayClipAtPoint( stormIntro, Vector3.zero, 0.7 ); Invoke( "StormMusic", introTime ); The way I'm currently trying to do it is get the length of the storm_intro audio clip, play the clip, and then invoke storm_loop to begin after the length of the intro has completed. This kinda works, but not really because there's occasionally a gap between the two. So how can I do it so the transition is seamless?

  • How many months of fixing somebody else's bugs would you endure?

    - by Hamish Grubijan
    I understand that fixing bugs is a way to learn the system for the new people. But what if the system is so large that you can fix other people's bugs for 2 years and still not learn about every aspect of it? I would imagine that most people would get bored and not give their 100% to fixing bugs caused by others. Is there something wrong with the process? Everybody is chanting "Scrum! Scrum!" and getting certified, but that is just another phrase to me. How do you get noticed if all you do is fix bugs? Stand by a water-cooler perhaps and brag about how cool my bug fixes are? My political beliefs seem to be opposite from everybody else's at the company, and I have zero interest in pop culture/trivia/Tiger Woods scandals - there goes my opportunity to socialize during a lunch hour.

  • Controling page number shown in printing dialog

    - by Matthias Wandel
    I'm trying to implement printing a range of pages in c# While printing, the .net framework throws up a message box that says "Page # of document". This starts at 1, and counts up to the number of pages printed. If I'm printing pages 10-11, I want that count to start at 10, not 1. Is there a way to set the starting value? The logical thing would be if it started at PrinterSettings.FromPage, but it ignores that value.

  • Lazy sequence or recur for mathematical power function?

    - by StackedCrooked
    As an exercise I implemented the mathematical power function. Once using recur: (defn power [a n] (let [multiply (fn [x factor i] (if (zero? i) x (recur (* x factor) factor (dec i))))] (multiply a a (dec n)))) And once with lazy-seq: (defn power [a n] (letfn [(multiply [a factor] (lazy-seq (cons a (multiply (* a factor) factor))))] (nth (multiply a a) (dec n)))) Which implementation do you think is superior? I truly have no idea.. (I'd use recur because it's easier to understand.) I read that lazy-seq is fast because is uses internal caching. But I don't see any opportunities for caching in my sample. Am I overlooking something?

Here is original image and resized one. Any good recommendation? Thanks, Ile

  • PHP & MySQL - saving and looping problems.

    - by R.I.P.coalMINERS
    I'm new to PHP and MySQL I want a user to be able to store multiple names and there meanings in a MySQL database tables named names using PHP I will dynamically create form fields with JQuery every time a user clicks on a link so a user can enter 1 to 1,000,000 different names and there meanings which will be stored in a table called names. Since I asked my last question I figured out how to store my values from my form using the for loop but every time I loop my values when I add one or more dynamic fields the second form field named meaning will not save the value entered also my dynamic form fields keep looping doubling, tripling and so on the entered values into the database it all depends on how many form fields are added dynamically. I was wondering how can I fix these problems? On a side note I replaced the query with echo's to see the values that are being entered. Here is the PHP code. <?php if(isset($_POST['submit'])) { $mysqli = mysqli_connect("localhost", "root", "", "site"); $dbc = mysqli_query($mysqli,"SELECT * FROM names WHERE userID='$userID'"); $name = $_POST['name']; $meaning = $_POST['meaning']; if(isset($name['0']) && mysqli_num_rows($dbc) == 0 && trim($name['0'])!=='' && trim($meaning['0'])!=='') { for($n = 0; $n < count($name); $n++) { for($m = 0; $m < count($meaning); $m++) { echo $name[$n] . '<br />'; echo $meaning[$m] . '<br /><br />'; break; } } } } ?> And here is the HTML code. <form method="post" action="index.php"> <ul> <li><label for="name">Name: </label><input type="text" name="name[]" id="name" /></li> <li><label for="meaning">Meaning: </label><input type="text" name="meaning[]" id="meaning" /></li> <li><input type="submit" name="submit" value="Save" /></li> </ul> </form> If needed I will place the JQuery code.

  • How can I filter a report with duplicate fields in related records?

    - by Graham Jones
    I have a report where I need to filter out records where there is a duplicate contract number within the same station but a different date. It is not considered a duplicate value becuase of the different date. I then need to summarize the costs and count the contracts but even if i suppress the "duplicate fields" it will summarize the value. I want to select the record with the most current date. Station Trans-DT Cost Contract-No 8 5/11/2010 10 5008 8 5/12/2010 15 5008 9 5/11/2010 12 5012 9 5/15/2010 50 5012

  • Recommend a local LDAP store for development

    - by Paul Stovell
    Our project uses an LDAP repository for storing users. In production this will be Active Directory. For development, we seem to have a couple of options: Install an AD LDS instance that everyone uses Install an AD LDS instance on every developer machine We're trying to keep the 'F5' experience as lightweight as possible, so installing things or relying on a central AD store aren't my favorite ideas. There are other LDAP servers, like Open LDAP. I was hoping there might be an LDAP server that simply talks to an XML file. This would allow us to store the XML file in source control and have something that is fast and works. Our nightly builds would still use AD to pick up any differences, but the hope is since we're using LDAP it should Just Work. Can you recommend an LDAP implementation that works well for zero-config shared-nothing development?

  • Easy way to keep counting up infinitely

    - by Andrew Alexander
    What's a good way to keep counting up infinitely? I'm trying to write a condition that will keep going until there's no value in a database, so it's going to iterate from 0, up to theoretically infinity (inside a try block, of course). How would I count upwards infinitely? Or should I use something else? I am looking for something similar to i++ in other languages, where it keeps iterating until failure.
