  • looping through new div as they are created

    - by eknown
    I have a div, let's call it class="phoneNo". Inside the div there are two links, one to add another div just like it, and another to delete the div itself. I'm trying to create a loop where if there's only 1 of these divs, the "delete" link should hide, and if there are more than 1 of these divs, the "delete" link should show up on all the divs. So far I came up with this, but no success: var pCount = $(".phoneNo").length; $(pCount).each(function(){ if (pCount <= 1) { $("a.deleteThis").hide(); } else if (pCount >= 1) { $("a.deleteThis").show(); } return true; });

  • Parallelism on two duo-core processor system

    - by Qin
    I wrote a Java program that draw the Mandelbrot image. To make it interesting, I divided the for loop that calculates the color of each pixel into 2 halves; each half will be executed as a thread thus parallelizing the task. On a two core one cpu system, the performance of using two thread approach vs just one main thread is nearly two fold. My question is on a two dual-core processor system, will the parallelized task be split among different processor instead of just utilize the two core on one processor? I suppose the former scenario will be slower than the latter one simply because the latency of communicating between 2 CPU over the motherboard wires. Any ideas? Thanks

  • Sign application with several certificates

    - by tschiggerl
    Hi, From the signing documentation at http://developer.android.com/intl/zh-TW/guide/publishing/app-signing.html: When the system is installing an update to an application, if any of the certificates in the new version match any of the certificates in the old version, then the system allows the update. This indicates that an application can be signed with multiple certificates. This is an interesting option to allow multiple entities to sign an application. e.g: A system application which was initially signed by the device's manufacturer. Further updates could be signed by the developer. Am I misreading the documentation or is this really possible? If so, how? Is there any other way for an application to support different certificates and with that, having two or more entities sign it? Thanks, Rúben

  • Disable Bluetooth discoverable mode on Android

    - by Venator85
    Hi, I found in the Android documentation how to turn Bluetooth discoverability mode on: Intent discoverableIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_DISCOVERABLE); discoverableIntent.putExtra(BluetoothAdapter.EXTRA_DISCOVERABLE_DURATION, 300); startActivity(discoverableIntent); This will make the device discoverable for 300 seconds (documentation). My question is: how to turn discoverability OFF before this timeout occurs? I'd like to replicate the corresponding setting in Settings|Wireless and networks|Bluetooth settings applet, that allows discoverability to be turned on and off with a click. Any help? Thanks ;)

  • C++ boost thread id and Singleton

    - by aaa
    hi. Sorry to flood so many questions this week. I assume thread index returned by thread.get_id is implementation specific. In case of the pthreads, is index reused? IE, if thread 0 runs and joins, is thread launched afterwords going to have a different ID? the reason I ask this is a need to implement Singleton pattern with a twist: each thread gets its own instance. I know it sounds very crazy, but threads control hardware (cuda) which does not permit device memory sharing. What is a good way to implement such pattern?

  • Android emulator-5554 offline

    - by hanesjw
    I'm having a problem with emulator-5554, it keeps telling me it is offline. When I do a 'adb devices' from the command line it says emulator-5554 offline Even after a fresh restart, I try that command and it still says it is offline. The problem is when I try to install .apk files to the emulator using 'abd install path' from the command prompt, it tells me that it is offline, if I create another device and run that one, then try to install the .apk files, it says i have too many devices connected. So in other words, I can't install my .apk files. How in the world can I get rid of that damn emulator-5554? I heard that if you do a restart, it should clear all the devices, but that does not seem to be working. It is like it is getting initialized when my computer starts up. Has anyone run into this issue? Thanks

  • php date() stuck

    - by WAC0020
    I am getting the date from my mysql database and that date is correct but when I use the date() function the minute part is stuck a 6 minutes. My mysql is returning 2010-06-15 09:59:18 Then in php I use this code: date('M d,Y H:m A',strtotime($row[4])) ** $row[4] is from my while loop ** When I echo this out I get: Jun 15,2010 9:06 AM I also have tried converting it to unix timestamp in my sql query, does the same thing. I noticed that the hours work and the seconds work but the minutes are stuck at 6. Does anyone have any ideas on what is going on?

  • Removing duplicates (within a given tolerance) from a Numpy array of vectors

    - by Brendan
    I have an Nx5 array containing N vectors of form 'id', 'x', 'y', 'z' and 'energy'. I need to remove duplicate points (i.e. where x, y, z all match) within a tolerance of say 0.1. Ideally I could create a function where I pass in the array, columns that need to match and a tolerance on the match. Following this thread on Scipy-user, I can remove duplicates based on a full array using record arrays, but I need to just match part of an array. Moreover this will not match within a certain tolerance. I could laboriously iterate through with a for loop in Python but is there a better Numponic way?

  • Is there an Objective-C algorithm like `transform` of the C++ STL?

    - by pesche
    My goal is to have an array that contains all filenames of a specific extension, but without the extension. There's an elegant solution to get all filenames of a specific extension using a predicate filter and instructions on how to split a path into filename and extension, but to combine them I would have to write a loop (not terrible, but not elegant either). Is there a way with Objective-C (may be similar to the predicate mechanism) to apply some function to every element of an array and put the results in a second array, like the transform algorithm of the C++ STL does?

  • [java] Threading socket handler for two sided communication in tcp port

    - by raven
    I want to make a chat which will be programed in java. one computer will host the server and the other one will initiate the socket [tcp port]. now from what I read there should be a loop that will constantly read the socket which means it will make the code stuck. I have a button that is 'actionperformed' on mouse release, I want to know if it will work along with the loops that constantly reads the socket so that it will also send the infromation I wrote. If I must thread it, I want to know if the run() method must be void because if I thread it it will mean creating a new class, and the whole GUI is one big class which includes a text area, and it's private. also how can I extract the information from the socket directly to the text area? lets say the textarea variable is called "chatOutput". thx :)

  • Copying a database into a new database including structure and data

    - by Jason
    In phpMyAdmin under operations I can "Copy database to:" and select Structure and data CREATE DATABASE before copying Add AUTO_INCREMENT value I need to be able to do that without using phpMyAdmin. I know how to create the database and user. I have a source database that's a shell that I can work from so all I really need is the how to copy all the table structure and data part. (I know, the harder part) system() & exec() are not options for me which rules out mysqldump. (I think) How can I loop through each table and recreate it's structure and data? Is it just looping through the results of SHOW TABLES then for each table looping through DESCRIBE tablename Then, is there an easy way for getting the data copied?

  • How to combine two arrays of same length to one array with two fields (not append/merge)

    - by Raj
    Say, I have an array with months $months = array('Jan', 'Feb', 'Mar'...'Dec'); And another, with days (say, for year 2010) $mdays = array(31, 28, 31...31); I want to merge/combine these two arrays, into an array like this: $monthdetails[0] = ('month' => 'Jan', 'days' => 31) $monthdetails[1] = ('month' => 'Feb', 'days' => 28) ... $monthdetails[11] = ('month' => 'Dec', 'days' => 31) I can loop through both the arrays and fill the $monthdetails. I want to know whether there are any functions/easier way for achieving the same result. Thanks! Raj

  • cropped layout on the Android avd emulator

    - by SpellBound
    My application layout looks good on two slightly different avds I created in the development environment using Eclipse. However when I try to run these devices in the Emulator as standalone I see some missing buttons and cropped edges on the screen. I used the apk generated by Eclipse and installed it in the devices using adb - install. I want to know what the problem is. Also, any general guidelines to write an app that can run on any Android device for a given version. Thanks in advance.

  • Is my way of doing threads in Android correct?

    - by Charlie
    Hi, I'm writing a live wallpaper, and I'm forking off two separate threads in my main wallpaper service. One updates, and the other draws. I was under the impression that once you call thread.start(), it took care of everything for you, but after some trial and error, it seems that if I want my update and draw threads to keep running, I have to manually keep calling their run() methods? In other words, instead of calling start() on both threads and forgetting, I have to manually set up a delayed handler event that calls thread.run() on both the update and draw threads every 16 milliseconds. Is this the correct way of having a long running thread? Also, to kill threads, I'm just setting them to be daemons, then nulling them out. Is this method ok? Most examples I see use some sort of join() / interrupt() in a while loop...I don't understand that one...

  • staying within boundaries of image?

    - by codefail
    So I am to loop through copyFrom.pixelData and copy it into pixelData. I realize that I need to check the conditions of i and j, and have them not copy past the boundaries of pixelData[x][y], I need another 2 loops for that? I tried this, but was getting segmentation fault.. Is this the right approach? void Image::insert(int xoff, int yoff, const Image& copyFrom, Color notCopy) { for (int x = xoff; x < xoff+copyFrom.width; x++) { for (int y = yoff; y < yoff+copyFrom.height; y++) { for (int i = 0; i<width; i++){ for (int j = 0; j<height; j++){ if (copyFrom.pixelData[i][j].colorDistance(notCopy)>20 ) pixelData[x][y]=copyFrom.pixelData[i][j]; } } } } }

  • Virtualhost subdomain Internal Server Error

    - by Andrew
    I am trying to set up user generated sub domains for my PHP application. When I go to sub.domain.com and if I upload an index.html file it works fine, however if I use index.php it gives me a "Internal Server Error 500" message I have done the steps below to get subdomains working STEP 1: Edited my DNZ zone file and appended *.domain.com. IN A 91.111.111.111 STEP 2: Appended to httpd.conf the following: <VirtualHost 91.111.111.111:80> ServerName domain.com ServerAlias *.domain.com DocumentRoot /home/domain/public_html/sub <Directory "/home/domain/public_html/sub"> Options -Indexes Options FollowSymLinks AllowOverride All </Directory> </VirtualHost> Step 3: Tested by uploading an index.html file to the document directory in step 2, and works fine. Tried with an index.php gives a internal server error and then I looked into Apache error log and shows error for a redirect loop more than 10 times Update: getting this error: No user or group set - set suPHP_UserGroup Any ideas why I can not use any .php file in the directory?

  • Fastest algorithm to check if a number is pandigital?

    - by medopal
    Pandigital number is a number that contains the digits 1..number length. For example 123, 4312 and 967412385. I have solved many Project Euler problems, but the Pandigital problems always exceed the one minute rule. This is my pandigital function: private boolean isPandigital(int n){ Set<Character> set= new TreeSet<Character>(); String string = n+""; for (char c:string.toCharArray()){ if (c=='0') return false; set.add(c); } return set.size()==string.length(); } Create your own function and test it with this method int pans=0; for (int i=123456789;i<=123987654;i++){ if (isPandigital(i)){ pans++; } } Using this loop, you should get 720 pandigital numbers. My average time was 500 millisecond. I'm using Java, but the question is open to any language.

  • Isolating read and write in multithreaded

    - by the_lotus
    Hi In a multithreaded application. I have a bunch of function that loop through a collection to read the information. I also have a bunch of function that modifies that same collection. I’m looking for a way to isolate all the read and the write together. I don’t want a write to be done while a read is in progress. I was thinking of using SyncLock on the collection object but this will block multiple read trying to work in parallel.

  • matlab: simple matrix filtering - group size

  • How to use the watchdog timer in a RTOS?

    - by user946230
    Assume I have a cooperative scheduler in an embedded environment. I have many processes running. I want to utilize the watchdog timer so that I can detect when a process has stopped behaving for any reason and reset the processor. In simpler applications with no RTOS I would always touch the watchdog from the main loop and this was always adequate. However, here, there are many processes that could potentially hang. What is a clean method to touch the watchdog timer periodically while ensuring that each process is in good health? I was thinking that I could provide a callback function to each process so that it could let another function, which oversees all, know it is still alive. The callback would pass a parameter which would be the tasks unique id so the overseer could determine who was calling back.

  • What can't the NDK be used for?

    - by Android Eve
    From the official NDK site: The Android NDK... provides headers and libraries that allow you to build activities, handle user input, use hardware sensors, access application resources, and more, when programming in C or C++. If you write native code, your applications are still packaged into an .apk file and they still run inside of a virtual machine on the device. The fundamental Android application model does not change. Yet, it is always described as a companion tool to the Android SDK and as a toolset that allows to "implement parts of your applications using native-code languages such as C and C++". My understanding from this is that, unlike the Java based SDK, the NDK is not designed to implement certain parts of an Android application. Is this correct? If so, what parts doesn't the NDK allow implementing?

  • Transform shape built of contour splines to simple polygons

    - by Cheery
    I've dumped glyphs from truetype file so I can play with them. They have shape contours that consist from quadratic bezier curves and lines. I want to output triangles for such shapes so I can visualize them for the user. Traditionally I might use libfreetype or scan-rasterise this kind of contours. But I want to produce extruded 3D meshes from the fonts and make other distortions with them. So, how to polygonise shapes consisting from quadratic bezier curves and lines? There's many contours that form the shape together. Some contours are additive and others are subtractive. The contours are never open. They form a loop. (Actually, I get only contour vertices from ttf glyphs, those vertices define whether they are part of the curve or not. Even though it is easy to decompose these into bezier curves and lines, knowing the data is represented this way may be helpful for polygonizing the contours to triangles)
