• Bash init.d script detect that mysqld has started and is running

  - by Ricket

  I'm working on my dedicated server running CentOS. I found out that one of my applications which starts up via a script in /etc/init.d/ requires MySQL to be running, or else it throws an error, so essentially I currently have to start it by hand. How can I detect, in a bash script (#!/bin/sh), whether the MySQL service has started yet? Is there some way to poll port 3306 until it is open to accept connections, and only then continue with the script? Or maybe set an order so that the script doesn't run until the mysqld script runs?

• After grouping by, can I refer to the elements of the original IEnumerable in a LINQ query?

  - by michielvoo

  Example: from OriginalObject in ListOfOriginalObjects group new CustomObject { X = OriginalObject.A, Y = OriginalObject.B } by OriginalObject.Z into grouping select new GroupOfCustomObjects { Z = grouping.Key, C = OriginalObject.C, group = grouping } In the select part of the query, I'd like to add a property (OriginalObject.C) to the type GroupOfCustomObjects. But it seems that OriginalObject is out of scope in that part of the query. I can sort of understand why, since I am not grouping on that property and I am also not making that property part of CustomObject that I'm grouping. One workaround is to add a property C to CustomObject and the in the GroupOfCustomObjects read the value of the first CustomObject in the grouping. My issue with that is that I'm adding a property to an object that doesn't need it (CustomObject), just to be able to add it to the GroupOfCustomObjects. I hope I have explained this properly! Is there a way to refer to the OriginalObject that the query starts with? Thanks!

• Build config file into executable?

  - by REM

  I am currently working on a little graphics demo (using DirectX) which is primarily based around an HLSL shader I am working on. Using the D3DX10CreateEffectFromFile I am loading (and compiling the shader) at runtime as I find it easier for tweaking. However, once I am done I'd like to do some combination of the following: Pre-compile the shader so the demo starts up faster for the user Bury (compile into the executable) the compiled shader (or maybe just the source if necessary) Primarily, I want to do this because I want the demo to just be one file that can be very easily copied around. One thing I could easily do is just put the source text right into a cpp but that would be very tedious I needed to update it later. Is it possible to do something like this (using Visual Studio, DirectX, HLSL)?

• Find domain of a user from Active Directory

  - by bhanu

  Wrote a java code to search for users from Active Directory server. We get the user list but dont know the domain to which each user belongs. How can the domain of the user be found from Active Directory programatically. One method thought of is : 1)Get the distinguished name of user from Active Directory. 2)Parse the distinguished name. 3)Get the substring that starts the first instance of "DC=". 4)Strip off the "DC=" at the beginning. 5)Replace all instances of ",DC=" with a "." 6)What is left is the DNS domain name of the user. Is this reliable. Please suggest some other solution.

• Screen orientation change forces data re-entry

  - by Timbermar

  I'm developing a simple app, only a handful of activities and nothing to complicated. The issue I'm having is that in a few of my activities I have EditText widgets, and when the screen is rotated, these widgets loose their values. They still visually, that is, on the handset screen, report their values from before the rotation, but to the code report their default values. An example, I have an activity with an EditText, I enter a number, 15, the calculator starts calculating, displays a result. If at this point I rotate to a different orientation, as expected the activity dies, reloads, shows the new orientation, my value of 15 is still in the EditText, however the calculator (the code) calculates as if it was 0, which is the initial value. I have not tried changing the initial value to see if it is really pulling from the default value, or just setting itself to 0 when I cast it as an int. If I didn't explain this well enough, let me know, I can add source code if I need to. Thanks.

• If Else Conditionals within Function in JavaScript

  - by Antoine-Laurent Lavoisier

  I'm having issues with conditionals. I want to return the index where pattern starts in string (or -1 if not found). The search is to be case sensitive if the 3rd parameter is true otherwise it is case insensitive. Examples index("abAB12","AB",true) returns 2 but index("abAB12","AB",false) returns 0 index("abAB12","BA",true) returns -1 and index("abAB12","BA",false) returns 1 Any idea how I can accomplish this? This is my code so far var s = "abAB12" var p = "AB" var cs = true function index(string, pattern, caseSensitive) { if (pattern) { var found = false; if (caseSensitive = false) { if (string.indexOf(pattern.) >= 0) { found = true; } return (found); else { return (""); } } else if (caseSensitive = true) { if (string.toLowerCase().indexOf(pattern.toLowerCase()) >= 0) { found = true; } return (found); } else { return (""); } } } alert(index(s, p, cs)); Fiddle at http://jsfiddle.net/AfDFb/1/

• How do I make a expanding textbox?

  - by jpjp

  I want to make a textbook where it starts out as a given width/height. Then if users type more then the given amount of space, the textbox expands downward. How do I go about doing this? Do I use css? The basic textbox just displays a scroll bar when users pass the number of rows allow. How do I make it so the textbox expands the rows by say 5 more? <form method="post" action=""> <textarea name="comments" cols="50" rows="5"></textarea><br> <input type="submit" value="Submit" /> </form> How do i use the example that Robert Harvey mentioned? I never used javascript before..

• Data format for content heavy iPhone app - Plist or XML?

  - by Toby

  Hello, I'm building an iPhone app that is essentially a book, it will be bundled with a lot of text-heavy content. I considered bundling the data as XML and load it when the application starts but the XML would contain a lot of nested structures and be a bit of a pain to parse. Would it be better to use a plist? I'm concerned about memory usage and plists are loaded entirely into memory - can they be parsed in chunks? Is there a maximum size to a plist and how efficient are they? I'm not sure how big the bundled content is going to be yet but I should imagine it could be anywhere from 500k to 4MB. Thanks in advance.

• How to test if a string has a certain unicode char?

  - by Ruben Trancoso

  Supose you have a command line executable that receives arguments. This executalbe is widechar ready and you want to test if one of this arguments starts with an HYPHEN case in which its an option: command -o foo how you could test it inside your code if you don't know the charset been used by the host? Should be not possible to a given console to produce the same HYPHEN representation by another char in the widechar forest? (in such case it would be a wild char :P) int _tmain(int argc, _TCHAR* argv[]) { std::wstring inputFile(argv[1]); if(inputFile->c_str() <is an HYPHEN>) { _tprintf(_T("First argument cannot be an option")); } }

• How to stop a Timer-X timer (jQuery)

  - by Damien K.

  I'm using Timer-X's timerDelayCall function in order to have a repeating rotator on my page, which starts automatically as the page loads: jQuery.timerDelayCall({ interval: 2000, repeat: true, callback: function(timer) { ... (my rotator logic here) } } }); The problem is that I'm trying to make a function that includes stopping that timer: function signUp() { ... (timer stop code here) } The documentation stats that timer.stop() does that, but however I format it, I get errors about it not being declared. I have tried every variation I can think of, such as: timer.stop(); jQuery.timer.stop(); $(document).timer.stop(); jQuery.timerDelayCall({ callback: function(timer) { timer.stop() } }); I'm sure I'm missing something simple - I come from a PHP background yet I'm new to javascript - but can't see what it is exactly. Help is much appreciated!

• slow android emulator

  - by Andrie

  I have a 2.67GHz Celeron Processor, 1.21GBs of RAM on a x86 Windows XP Pro machine. My understanding is that the emulator should start fairly quickly on such a machine, but for me it does not. I have followed all instructions in setting up the IDE, SDKs, JDKs and such and have had some success in staring the emulator quickly but is very particulary. How can I if possible fix this problem. Even if it starts and loads home screen it is very sluggish. Any help would be appreciated guys thanks. I have tried the Eclipse IDE in Galileos, and Ganymede.

• Error in vb.net windows service when connecting to SQL

  - by Clint

  I've installed a vb.net windows service on a Windows 2008 machine, that is attempting to connect to SQL 2005. The service starts succesfully, but can't see the database.

• Update model objects across different activities

  - by Tom Esterez

  Lets say I have 2 activities: A: A ListView displaying articles titles. Data is fetched from a web server and converted from XML to a list of ArticleSummary. Only user titles and id are returned by the server. Click on a title starts activity B. B: A form to edit an article. Article is fetched from server. When the user hits OK, modifications are sent to the server and activity closed. When the user go back to activity A, I would like to update the article title without any additional web request. I was thinking about the following solution: When article is modified, send a broadcast event with article id and new attributes values. Listen for this event on activity A Update the ArticleSummary object notify data changed on ListView Is there a better approach ?

• problem with TEMPORARY TABLE

  - by Z77

  Within PHP I do: 1.) A temporary table is created: CREATE TEMP TABLE new_table AS SELECT .... FROM ...; 2.) AFter that I want to use this table to create a shape file: shell_exec ("pgsql2shp .... -u username -P password ...); Separetly those two things work, but by creating a temporary table and after that using this table in pgsql2shp does not work. I pressume this is because temporary table duration is to the end of session. But to create shp file I need to use username and password what means new session starts and temporary table is dropped before I use it for shape creation. Any tip how to solve it? Thank you!

• How do detect that transaction has already been started?

  - by xelurg

  I am using Zend_Db to insert some data inside a transaction. My function starts a transaction and then calls another method that also attempts to start a transaction and of course fails(I am using MySQL5). So, the question is - how do I detect that transaction has already been started? Here is a sample bit of code: try { Zend_Registry::get('database')->beginTransaction(); $totals = self::calculateTotals($Cart); $PaymentInstrument = new PaymentInstrument; $PaymentInstrument->create(); $PaymentInstrument->validate(); $PaymentInstrument->save(); Zend_Registry::get('database')->commit(); return true; } catch(Zend_Exception $e) { Bootstrap::$Log->err($e->getMessage()); Zend_Registry::get('database')->rollBack(); return false; } Inside PaymentInstrument::create there is another beginTransaction statement that produces the exception that says that transaction has already been started.

• How to draw or put a text on empty an UITableViewController ?

  - by elementsense

  Hi I have a app that starts with a empty UITableViewController, which is pretty .. well, emtpy. Now I was wondering if I could hint the user by painting something else on the view, like pointing an arrow to the plus button and say something like "press here to add something new" I'll guess I have to do this in the viewDidLoad method, where I also init my NSFetchedResultsController, so I actually know if there are any objects in my list. I never put controls on the screen by code so I am not sure where to start and where to put em on. will that be the [self view] ? Thanks

• How to stop Interruptible Threads in Java

  - by Dr.Lesh

  I have a Java application that I CAN'T EDIT that starts a Thread wich has this run method: public void run(){ while(true){ System.out.println("Something"); } } And at a certain moment I wanna stop it, but if I use thread.interrupt(); it won't work. If I use thread.stop(); it works, but this method is deprecated and its use is discouraged because soon it will be removed from JVM. Does anyone knows how to do it? Thank you.

• How to optimize indexing of large number of DB records using Zend_Lucene and Zend_Paginator

  - by jdichev

  So I have this cron script that is deployed and ran using Cron on a host and indexes all the records in a database table - the index is later used both for the front end of the site and the backed operations as well. After the operation, the index is about 3-4 MB. The problem is it takes a lot of resources (CPU: 30+ and a good chunk of memory) and slows the machine down. My question is about how to optimize the operation described below: First there is a select query built using the Zend Framework API, this query is then passed to a Paginator factory that returns a paginator which I am using to balance the current number of items being indexed and not iterate over too much items. The script is iterating over the current items in the paginator object using a foreach loop until reaching the end and then it starts from the beginning after getting items for the next page. I am suspecting this overhead is caused by the Zend_Lucene but no idea how this could be improved.

• AsyncTask won't stop even when the activity has destroyed

  - by Raja

  Hi all, I have an AsyncTask object which starts executing when the activity is created and does stuff in the background (downloads upto 100 images). Everything works fine but there is this peculiar behavior which i'm not able to understand. For eg: when the android screen's orientation changes then the activity is destroyed and created again. So I override the onRetainNonConfigurationInstance() method and save all the downloaded data executed in the AsyncTask. My purpose of doing this is to not have AsyncTask run each time activity is destroyed-created during orientation changes, but as i can see in my logs the previous AsynTask is still executing. (The data is saved correctly though) I even tried to cancel the AsynTask in the onDestroy() method of the activity but the logs still show AsynTask as running. This is really strange behavior and would really be thankful if someone can tell me the correct procedure to stop/cancel the AsynTask. Thanks

• jQuery mobile swipe spamming and animation

  - by halliewuud

  I have say 5 list items with images inside placed 200px from eachother. I am trying to animate these list items to slide horizontally left if one presses a link with the id = #next or if one swipes left. And vice versa for sliding the list items right. Every click or swipe results in a slide animation of 200px on every list item. I ran into a problem where spamming the #next or #prev button would cancel the current animation and start a new one. This results in list items not sliding 200px+200px+200... but something like this 200px+140px+120... This because like I said the animation is cut and therefore the sliding distance will be shorter. Now I solved this for the clicking event by disabling the button before the animation starts and then re'enabling it on the end callbak function. But this problem is remaining for the swipe event. How can I solve this problem for the swipe event?

• Pygame's Message-multiple lines?

  - by Jam

  I am using pygame and livewires (though I don't think that part is relevant here) to create a game. I've got the game working, but I'm trying to make something akin to a title screen before the game starts. However, it doesn't recognize when I try to make a new line appear. Here is what I have: begin_message=games.Message(value=""" Destroy the Bricks!\n In this game, you control a paddle,\n controlled by your mouse,\n and attempt to destroy all the rows of bricks.\n Careful though, you only have 1 life.\n Don't mess up! The game will start in\n 5 seconds.""", size=30, x=games.screen.width/2, y=games.screen.height/2, lifetime=500, color=color.white, is_collideable=False) games.screen.add(begin_message) The message appears on the screen, but the newline doesn't happen, so I can only read the first part of the message. Is there a way to make this message actually appear, or can I not use the 'Message' for this?

• SoundManager + FFMPEG causing loud popping sound when streaming MP3s?

  - by David

  Hi there, I built an application that plays both uploaded original mp3 files, and copies that have been converted with FFMPEG. I am finding that in some cases the FFMPEG files have a horrible popping/clicking/screeching sound for a split second at startup (hear below). But when I analyze the file in an audio editor there is nothing there, so it seems to be either the browser or soundManager reacting badly to something in that file. Wondering if there is any way I can fix this either by adjusting FFMPEG settings, soundManager settings, or..... Any suggestions? I've uploaded the offending sound in the link below (before the music starts playing). Thanks for your help! Hear sound

• Does deleting temporary symlinks interrupt current downloads/access to that symlink?

  - by Joe

  I am using symlinks generated in PHP. They are generated when someone requests a download, and I want them to expire at the end of each day. The problem is, what if someone starts downloading a symlink 1 minute before the end of the day and then I delete the symlink while they are downloading it... My question is, to your knowledge will that individual downloading the symlink, right before I delete it, still be able to "download" the file? I am not worried about "resumable download" capability.. but will it make their download stop or break in some way?
