• JDialog setResizable(false) is not working in Window Title Bar Menu

  - by jolonaleur

  JDialog setResizable(false) is not working in Window Title Bar Menu Windows XP SP2 Java JRE 1.6.0_11-b03 Behavior varies. Sometimes, the Maximize and Minimize item on the window menu is disabled and sometimes enabled. Steps to reproduce enabled Maximize and Minimize button: Show the JDialog with setResizable(false) Open another window, say for example Notepad. Right-click on the window title bar of Notepad and click Maximize. Go to your JDialog and right click on the window title bar. Maximize window is enabled. Likewise, to disable the Maximize item for the JDialog, go to the maximized Notepad window and right click on title bar. Maximize item is disabled in the Notepad window. Go the your JDialog and right click on the title bar, notice that the Maximize item is also disabled. Note that my application can not use the defaultLookAndFeel method of java dialogs. The bug report related to this was for Solaris OS but that was already ages ago. bug report Is there any workaround? Thanks.

• How to use Nhibernate Validator + NHib component + ddl

  - by mynkow

  I just configured my NHibValidator. My NHibernate creates the DB schema. When I set MaxLenght="20" to some property of a class then in the database the length appears in the database column. I am doing this in the NHibValidator xml file. But the problem is that I have components and cannot figure out how to achieve this behaviour. The component is configured correctly in the Customer.hbm.xml file. EDIT: Well, I found that Hibernate Validator users had the same problem two years ago. http://opensource.atlassian.com/projects/hibernate/browse/HV-25 Is this an issue for NHibernate Validator or it is fixed. If it is working tell me how please. ----------------------------------------------------- public class Customer { public virtual string Name{get;set;} public virtual Contact Contacts{ get; } } ----------------------------------------------------- public class Contact { public virtual string Address{get;set;} } ----------------------------------------------------- <?xml version="1.0" encoding="utf-8" ?> <nhv-mapping xmlns="urn:nhibernate-validator-1.0" namespace="MyNamespace" assembly="MyAssembly"> <class name="Customer"> <property name="Name"> <length max="20"/> </property> <property name="Contacts"> <notNull/> <valid/> </property> </class> </nhv-mapping> ----------------------------------------------------- <?xml version="1.0" encoding="utf-8" ?> <nhv-mapping xmlns="urn:nhibernate-validator-1.0" namespace="MyNamespace" assembly="MyAssembly"> <class name="Contact"> <property name="Address"> <length max="50"/> <valid/> </property> </class> </nhv-mapping> -----------------------------------------------------

• C#. How to pass message from unsafe callback to managed code?

  - by maxima120

  Is there a simple example of how to pass messages from unsafe callback to managed code? I have a proprietary dll which receives some messages packed in structs and all is coming to a callback function. The example of usage is as follows but it calls unsafe code too. I want to pass the messages into my application which is all managed code. *P.S. I have no experience in interop or unsafe code. I used to develop in C++ 8 yrs ago but remember very little from that nightmarish times :) P.P.S. The application is loaded as hell, the original devs claim it processes 2mil messages per sec.. I need a most efficient solution.* static unsafe int OnCoreCallback(IntPtr pSys, IntPtr pMsg) { // Alias structure pointers to the pointers passed in. CoreSystem* pCoreSys = (CoreSystem*)pSys; CoreMessage* pCoreMsg = (CoreMessage*)pMsg; // message handler function. if (pCoreMsg->MessageType == Core.MSG_STATUS) OnCoreStatus(pCoreSys, pCoreMsg); // Continue running return (int)Core.CALLBACKRETURN_CONTINUE; } Thank you.

• Python modules not updating after restarting the main module.

  - by Ian

  I've recently come back to a project having had to stop for about 6 months, and after reinstalling my operating system and coming back to it I'm having all kinds of crazy things happen. I made sure to install the same version(2.6) of python that I was using before. It started by giving me strange tkinter error that I hadn't had trouble with before, the program is relatively simple and the 2 or 3 bugs that were left when i quit, I had documented and weren't related to the interface. Things got even weirder when the same error would pop up even after I had removed the offending section of code. In fact, the traceback pointed to a line that didn't even exist in the module it was referencing, eg: line 262 when the module was only 200 lines long. After just starting a completely new file for the main module and copy/pasting it finally recognized that the offending code was gone and I stopped getting the error only to find that any updates to the code I made in another module didn't show up when I restarted the program through the shell. (I didn't forget to save.) After fiddling with this, of course, the old interface error came back, only in a different section of code that had been working previously. In fact, if I revert back to the files I had six months ago, the program works fine. As soon as I change anything in the main module, however, the interface bug comes back. Here's the original error: Exception in Tkinter callback Traceback (most recent call last): File "C:\Python26\lib\lib-tk\Tkinter.py", line 1410, in __call__ return self.func(*args) File "C:\PyStuff\interface.py", line 202, in dispOne __main__.top.destroy() File "C:\Python26\lib\lib-tk\Tkinter.py", line 1938, in destroy self.tk.call('destroy', self._w) TclError: can't invoke "destroy" command: application has been destroyed I'm guessing something else is going on here other than my own poor programming. Anyone have any ideas?

• How should I secure my webapp written using Wicket, Spring, and JPA?

  - by Martin

  So, I have an web-based application that is using the Wicket 1.4 framework, and it uses Spring beans, the Java Persistence API (JPA), and the OpenSessionInView pattern. I'm hoping to find a security model that is declarative, but doesn't require gobs of XML configuration -- I'd prefer annotations. Here are the options so far: Spring Security (guide) - looks complete, but every guide I find that combines it with Wicket still calls it Acegi Security, which makes me think it must be old. Wicket-Auth-Roles (guide 1 and guide 2) - Most guides recommend mixing this with Spring Security, and I love the declarative style of @Authorize("ROLE1","ROLE2",etc). I'm concerned about having to extend AuthenticatedWebApplication, since I'm already extending org.apache.wicket.protocol.http.WebApplication, and Spring is already proxying that behind org.apache.wicket.spring.SpringWebApplicationFactory. SWARM / WASP (guide) - This looks the newest (though the main contributor passed away years ago), but I hate all of the JAAS-styled text files that declare permissions for principals. I also don't like the idea of making an Action class for every single thing a user might want to do. Secure models also aren't immediately obvious to me. Plus, there isn't an Authn example. Additionally, it looks like lots of folks recommend mixing the first and second options. I can't tell what the best practice is at all, though.

• What could cause these Apache crash errors ?

  - by jacobanderssen

  Hello guys. I had a server crash several days ago. I use Cacti to keep stats: at the time when the server crashed, a huge spike from Load 1 to Load 200 occurred, with over 800 processes in the run queue ( from 300 average).

• Are bad data issues that common?

  - by Water Cooler v2

  I've worked for clients that had a large number of distinct, small to mid-sized projects, each interacting with each other via properly defined interfaces to share data, but not reading and writing to the same database. Each had their own separate database, their own cache, their own file servers/system that they had dedicated access to, and so they never caused any problems. One of these clients is a mobile content vendor, so they're lucky in a way that they do not have to face the same problems that everyday business applications do. They can create all those separate compartments where their components happily live in isolation of the others. However, for many business applications, this is not possible. I've worked with a few clients, one of whose applications I am doing the production support for, where there are "bad data issues" on an hourly basis. Yeah, it's that crazy. Some data records from one of the instances (lower than production, of course) would have been run a couple of weeks ago, and caused some other user's data to get corrupted. And then, a data script will have to be written to fix this issue. And I've seen this happening so much with this client that I have to ask. I've seen this happening at a moderate rate with other clients, but this one just seems to be out of order. If you're working with business applications that share a large amount of data by reading and writing to/from the same database, are "bad data issues" that common in your environment?

• Cheap cloning/local branching in Mercurial

  - by Zack

  Hi, Just started working with Mercurial a few days ago and there's something I don't understand. I have an experimental thing I want to do, so the normal thing to do would be to clone my repository, work on the clone and if eventually I want to keep those changes, I'll push them to my main repository. Problem is cloning my repository takes alot of time (we have alot of code) and just compiling the cloned copy would take up to an hour. So I need to somehow work on a different repository but still in my original working copy. Enter local branches. Problem is just creating a local branch takes forever, and working with them isn't all that fun either. Because when moving between local branches doesn't "revert" to the target branch state, I have to issue a hg purge (to remove files that were added in the moved from branch) and then hg update -c (to revert modified files in the moved from branch). (note: I did try PK11 fork of local branch extension, it a simple local branch creation crashes with an exception) At the end of the day, this is just too complex. What are my options?

• Why are Facebook Likes Insisting on using Wrong Product Image...?

  - by Joan Kent

  Firstly, I'm not a web developer so please be patient. I have read the other posts but I think i have everything covered. My website http://www.joaniesgifts.co.uk includes the like button on the product pages. However, I've found that certain product pages are using the incorrect image when a user likes the page. For example - http://www.joaniesgifts.co.uk/terramundi-money-pots/terramundi-money-pot-holiday-fund I think this may have been down to an original incorrect setup which is now corrected. However, the problem remains... The only thing I have to go on :- if i use the facebook url linter (developers.facebook.com/tools/debug) on the above product page, I receive the following error :- Object at URL 'http://www.joaniesgifts.co.uk/terramundi-money-pot-holiday-fund' of type '213689662010141:product' is invalid because the domain 'www.joaniesgifts.co.uk' is not allowed for the application id '213689662010141' which owns the specified object type. If you are the owner of this application, you can verify your configured 'Site Domain' at developers.facebook.com/apps/213689662010141. (I have verified my site's domain) Everything else appears fine except it is also showing the wrong image!! However, under Raw Open Graph Document Information it has the correct link! If I then click graph api - graph.facebook.com/10150450766583352 it again shows the wrong image was linked! I've no idea what else to do - can you help me? Kind Regards, Joan PS Graph API shows the incorrect image after a scrape only minutes ago { "url": "http://www.joaniesgifts.co.uk/terramundi-money-pot-holiday-fund", "type": "website", "title": "Terramundi Money Pot - Holiday Fund", "image": [ { "url": "http://www.joaniesgifts.co.uk/index.php?route=product\u00252Fproduct\u00252Fcaptcha" } ], "updated_time": "2011-11-11T18:54:38+0000", "id": "10150450766583352" }

• Python: Errors saving and loading objects with pickle module

  - by Peterstone

  Hi, I am trying to load and save objects with this piece of code I get it from a question I asked a week ago: Python: saving and loading objects and using pickle. The piece of code is this: class Fruits: pass banana = Fruits() banana.color = 'yellow' banana.value = 30 import pickle filehandler = open("Fruits.obj","wb") pickle.dump(banana,filehandler) filehandler.close() file = open("Fruits.obj",'rb') object_file = pickle.load(file) file.close() print(object_file.color, object_file.value, sep=', ') At a first glance the piece of code works well, getting load and see the 'color' and 'value' of the saved object. But, what I pursuit is to close a session, open a new one and load what I save in a past session. I close the session after putting the line filehandler.close() and I open a new one and I put the rest of your code, then after putting object_file = pickle.load(file) I get this error: Traceback (most recent call last): File "<pyshell#5>", line 1, in <module> object_file = pickle.load(file) File "C:\Python31\lib\pickle.py", line 1365, in load encoding=encoding, errors=errors).load() AttributeError: 'module' object has no attribute 'Fruits' Can anyone explain me what this error message means and telling me how to solve this problem? Thank so much and happy new year!!

• HTML5 or Flash?

  - by lewiguez

  I have to write a web application for a client soon. Looking at the specs, there is no reason why the project couldn't be an HTML5/CSS/Javascript project, but the client is arguing that it has to be Flash. The project has a number of dynamic elements and is web-based. It'll only be used in-house by a small number of people and all of those people use either Google Chrome or Safari 4. They are all pretty tech-savvy to boot. My question is this: what are some of the reasons (preferably technical since this is Stack Overflow) I can present to my client as to why HTML5 is better than Flash (that's assuming I'm right and it is in this case)? Is it OK to use HTML5 even though it's still a draft spec (I'm assuming it is after checking out all those Apple HTML5 demos a few days ago)? Also, would a hybrid approach be preferable for now? Something that uses Flash wherever the canvas object would've been used in the HTML5 approach and that conforms to a normal XHTML approach. Help!

• Play Multiple iPod Library Songs On iPhone At The Same Time With Pitch Bending & Other Effects

  - by Dino

  Hi, I have been going at this for the past two weeks and it is driving me crazy. I asked this question a couple of days ago (Extract iPod Library raw PCM samples and play with sound effects) and whilst the answer got me half way there I am still stuck. Basically what I am trying to achieve is load up multiple songs from the iPod library for playback with effects such as pitch bend, eq effects etc... I have gone down the route of AVPlayer and AVAudioPlayer which are too simple. The only framework I've seen that can play audio with these effects is OpenAL. I have tried a few objective c wrappers (Finch and ObjectAL) Finch does not play compressed audio whilst ObjectAL will only convert it for me if I pass in a URL for the file (which is something I cannot do because I only have an incompatible iPod library URL). An example of an app that does what I want beautifilly is Tap DJ. It can load up songs from the iPod library fast (unlike TouchDJ and it plays them with all sorts of effects. Any help would be much appreciated.

• Batch File to Delete Folders

  - by Homebrew

  I found some code to delete folders, in this case deleting all but 'n' # of folders. I created 10 test folders, plus 1 that was already there. I want to delete all but 4. The code works, it leaves 4 of my test folders, except that it also leaves the other folder. Is there some attribute of the other folder that's getting checked in the batch file that's stopping it from getting deleted ? It was created through a job a couple of weeks ago. Here's the code I stole (but don't really understand the details): rem DOS - Delete Folders if # folders > n @Echo Off :: User Variables :: Set this to the number of folders you want to keep Set _NumtoKeep=4 :: Set this to the folder that contains the folders to check and delete Set _Path=C:\MyFolder_Temp\FolderTest If Exist "%temp%\tf}1{" Del "%temp%\tf}1{" PushD %_Path% Set _s=%_NumtoKeep% If %_NumtoKeep%==1 set _s=single For /F "tokens=* skip=%_NumtoKeep%" %%I In ('dir "%_Path%" /AD /B /O-D /TW') Do ( If Exist "%temp%\tf}1{" ( Echo %%I:%%~fI >>"%temp%\tf}1{" ) Else ( Echo.>"%temp%\tf}1{" Echo Do you wish to delete the following folders?>>"%temp%\tf}1{" Echo Date Name>>"%temp%\tf}1{" Echo %%I:%%~fI >>"%temp%\tf}1{" )) PopD If Not Exist "%temp%\tf}1{" Echo No Folders Found to delete & Goto _Done Type "%temp%\tf}1{" | More Set _rdflag= /q Goto _Removeold Set _rdflag= :_Removeold For /F "tokens=1* skip=3 Delims=:" %%I In ('type "%temp%\tf}1{"') Do ( If "%_rdflag%"=="" Echo Deleting rd /s%_rdflag% "%%J") :_Done If Exist "%temp%\tf}1{" Del "%temp%\tf}1{"

• How to .NET package JavaScript/bookmarklet as Interner Explorer 8/9 Plugin?

  - by Don

  How to .NET package JavaScript/bookmarklet as Interner Explorer 8/9 Plugin? I have recently finished writing JavaScript code for a browser addon, which basically (once the JS is included) runs on page-load, for given domains it then checks for certain elements in the DOM and adds new relevant elements(/information) to the page. Since the JavaScript only reads/affects the HTML DOM independently (and does not need any toolbar buttons or anything else) the JS purely needs adding to the browser's webpages. I have packaged the code to work with Firefox and Chrome and those are both working well, and I can run the code for IE in 'bookmarklet' form without problems, but I would like to learn how to package JavaScript as an actual .NET .MSI addon/plugin that will install for the current Internet Explorer 8/9. Does anyone know of a suitable guide or method I might refer to please? I have tried searching online for tutorials but most walkthroughs refer to writing the plugin body itself (which might involve unnecessary stages/includes) and are thus not regarding packing existing JS. I hope someone might have the solution please? Note: Someone packaged an old version for me as a MSI installer for Internet Explorer 7 a year ago, which installed into Program Files with a plugin.dll plugin.tlb and plugin.InstallState plus BandObjectLib.dll Interop.SHDocVw.dll and Microsoft.mshtml.dll if that is useful.

• CSS Flexible Height with scrollable content

  - by th3hamburgler

  I'm looking to create a flexible width/height page layout with no window scrollbars! Any content that will not fit on the page should be scrollable independently with the overflow property. I've seen plenty of ways to construct flexible width layouts using just HTML and CSS. The following site does a pretty good job on that front: http://ago.tanfa.co.uk/css/layouts/css-3-column-layout-v1.html I wish to implement scrollable content within the 3 centre columns. The content should be scrollable not the column div. e.g. <div class="column"> <h4>Title</h4> <ul> <li>These</li> <li>Items</li> <li>Should</li> <li>Be</li> <li>Scrollable</li> <li>If</li> <li>They</li> <li>Exceed</li> <li>The</li> <li>Window</li> <li>Height</li> </ul> So far if the list exceeds the window height it pushes the footer off page. I'm not to bothered about it working on old versions of IE, although that would score bonus points!

• Determine target architecture of binary file in Linux (library or executable)

  - by Fernando Miguélez

  We have an issue related to a Java application running under a (rather old) FC3 on a Advantech POS board with a Via C3 processor. The java application has several compiled shared libs that are accessed via JNI. Via C3 processor is suppossed to be i686 compatible. Some time ago after installing Ubuntu 6.10 on a MiniItx board with the same processor I found out that the previous statement is not 100% true. The Ubuntu kernel hanged on startup due to the lack of some specific and optional instructions of the i686 set in the C3 processor. These instructions missing in C3 implementation of i686 set are used by default by GCC compiler when using i686 optimizations. The solution in this case was to go with a i386 compiled version of Ubuntu distribution. The base problem with the Java application is that the FC3 distribution was installed on the HD by cloning from an image of the HD of another PC, this time an Intel P4. Afterwards the distribution needed some hacking to have it running such as replacing some packages (such as the kernel one) with the i383 compiled version. The problem is that after working for a while the system completely hangs without a trace. I am afraid that some i686 code is left somewhere in the system and could be executed randomly at any time (for example after recovering from suspend mode or something like that). My question is: Is there any tool or way to find out at what specific architecture is an binary file (executable or library) aimed provided that "file" does not give so much information?

• Rails paginate existing array of ActiveRecord results

  - by SaoiseK

  Hello, I generally use will_paginate for the pagination in my app, but have hit a stumbler on my search feature. I'm using Thinking Sphinx for doing my full-text search, which returns results paginated. The problem I'm having is that after I've received the results from Thinking Sphinx, I need to merge them with some other results and re-order them. Once I've finished processing them I have an Array of results that is very different from the original from TS. As there could be 1000+ results in this Array Pagination is a necessity. The problem is that I can't figure out how to get will_paginate to play with an existing array. I've done some research and it seems the only solutions to this problem are from several years ago and are based around the old built-in Paginator class. The most recent one I could find that makes use of will_paginate was from devchix from mid-2007: http://www.devchix.com/2007/07/23/will_paginate-array/comment-page-1/ - I've given this a go but it doesn't seem to do anything for me. Are there any current methods for applying pagination (preferably via will_paginate) for existing arrays of AR results?

• Which open source repository or version control systems store files' original mtime, ctime and atime

  - by sampablokuper

  I want to create a personal digital archive. I want to be able to check digital files (some several years old, some recent, some not yet created) into that archive and have them preserved, along with their metadata such as ctime, atime and mtime. I want to be able to check these files out of that archive, modify their contents and commit the changes back to the archive, while keeping the earlier commits and their metadata intact. I want the archive to be very reliable and secure, and able to be backed up remotely. I want to be able to check files in and out of the archive from PCs running Linux, Mac OS X 10.5+ or Win XP+. I want to be able to check files in and out of the archive from PCs with RAM capacities lower than the size of the files. E.g. I want to be able to check in/out a 13GB file using a PC with 2GB RAM. I thought Subversion could do all this, but apparently it can't. (At least, it couldn't a couple of years ago and as far as I know it still can't; correct me if I'm wrong.) Is there a libre VCS or similar capable of all these things? Thanks for your help.

• changing asp .net web service namespace when already in productive state

  - by eloQ

  by some unfortunate events we published a web service with the tempuri-namespace a couple of months ago and no one did notice (not in our company, not the companies connecting to the web service) even though it's live since that time and lots of companies (~25 i guess) already access this web service. now i'm thinking of correcting that mistake and have the namespace fixed to a proper value. the only problem is: as soon as we would do it, all the programs and services connected to this web service would stop working. i can't really allow that to happen. is there any way to fix the namespace for future purpose or to have the web service operate under two namespaces as one web service? any tip at all what i could do to get rid of the tempuri-namespace and have it fixed without needing to synchronize the change with all the external companies? i'm all out of ideas, so any help would be much appreciated! thanks! I hope this question is alright here, first time user, found this through using search engines on my research and found tempuri.org related posts, just not the right one..

• How can I correctly calculate the direction for a moving object?

  - by Jakub Hampl

  I'm solving the following problem: I have an object and I know its position now and its position 300ms ago. I assume the object is moving. I have a point to which I want the object to get. What I need is to get the angle from my current object to the destination point in such a format that I know whether to turn left or right. The idea is to assume the current angle from the last known position and the current position. I'm trying to solve this in MATLAB. I've tried using several variations with atan2 but either I get the wrong angle in some situations (like when my object is going in circles) or I get the wrong angle in all situations. Examples of code that screws up: a = new - old; b = dest - new; alpha = atan2(a(2) - b(2), a(1) - b(1); where new is the current position (eg. x = 40; y = 60; new = [x y];), old is the 300ms old position and dest is the destination point. Edit Here's a picture to demonstrate the problem with a few examples: In the above image there are a few points plotted and annotated. The black line indicates our estimated current facing of the object. If the destination point is dest1 I would expect an angle of about 88°. If the destination point is dest2 I would expect an angle of about 110°. If the destination point is dest3 I would expect an angle of about -80°.

• PayPal sandbox anomalies

  - by Christian

  When testing some donations on my local machine, I set various key=value pairs to do various things (return to specific thank you page, get POST data from PayPal and not GET data and others) I also built my code around the response from the PayPal sandbox. BUT, when my code goes to the production server and we switch on live payments and test with real accounts and money, a few strange things happen; We get a GET response from PayPal - the URL is filled with crap. We get no transaction details. This is the biggie, no name, no txn_id, no dates, nothing. We get a handful of keys etc, its not totally empty and the payment has gone through, but nowhere near the verbosity of the sandbox. Curious about why this might be? It doesn't really make sense to have a sandbox (or dev environment) that is substantially different from the production environment. Or, am I missing something? EDIT: Still no response to my question in the PayPal Developer Forums. I don't even get a donation amount back from PayPal. Is this a setting maybe? EDIT #2: Two of you have suggested to check PDT and Auto-Return. The data analytics guy for the project only 2 hrs ago suggested the same. I have asked the client to confirm this. I can't see a setting for it in the Sandbox so can assume that it is enabled by default?

  I had the PostgreSQL drivers working on my RHEL 6. But after I installed Microsoft® SQL Server® ODBC Driver 1.0 for Linux I can no longer connect to PosgreSQL data sources. I can connect to SQL Server data sources fine. When I had this same issue a week ago I uninstalled MS SQL Server ODBC driver from Linux and it fixed the issue. I had to copy the psqlodbcw.so files from another machine to replenish the files. I don't want to do the same this time. I want both drivers to work on Linux. This time around the setup files got deleted: /usr/lib64/libodbcpsqlS.so. Replenishing it did not fix the issue. I kept getting the following error in spite of the file being present with rwx permisions: [root@localhost lib64]# isql -v STUDENT dsname pwd12345 [01000][unixODBC][Driver Manager]Can't open lib '/usr/lib64/psqlodbc.so' : file not found [ISQL]ERROR: Could not SQLConnect [root@localhost lib64]# Here is a printout of the file permissions: [root@localhost lib64]# ls -al p*.so lrwxrwxrwx. 1 root root 12 Dec 7 09:15 psqlodbc.so -> psqlodbcw.so -rwxr-xr-x. 1 root root 519496 Dec 7 09:35 psqlodbcw.so and my odbcinst.ini file looks as follows: [PostgreSQL] Description=ODBC for PostgreSQL Driver=/usr/lib/psqlodbc.so Driver64=/usr/lib64/psqlodbc.so Setup=/usr/lib/libodbcpsqlS.so Setup64=/usr/lib64/libodbcpsqlS.so FileUsage=1 UsageCount=4 I also referred to this link: http://mailman.unixodbc.org/pipermail/unixodbc-support/2010-September.txt

• Is there a best practice for concatenating MP3 Files, adjusting sample rates to match, while preserving original files?

  - by Scott

  Hello overflow community! Does anyone know if there is a "best practice" to concatenate mp3 files to create new files, while preserving the original files? I am working on a CentOS Linux machine, in command line. I will eventually call the command line from a PHP script. I have been doing research and I have come up with a process that I think could work. It combines general advice from different forums, blogs, and sources like this one. So here I go: Create a temporary folder Loop through files to create a new, converted copy, of file into a "raw" format (which one, I don't know. I didn't know "raw" files existed before too long ago. I could use some suggestions on this) Store the path to the temporary files, in the temporary folder, and then loop through the files to concatenate them and then put the new merged file the final "processed directory" Delete the contents of the temporary file with the temporary raw files inside. Convert the final file from "raw" to mp3 and enjoy the finished result I'm thinking that this course of action might be best because I can't necessarily control the quality of the original "source" mp3s. The only other option I could think of would be to create a script that would perform a similar process upon files being added to the system leaving only the files with the "proper" format and removing the original "erroneous" file. Hopefully you can see that I have put some thought into this and that I'm trying to leverage the collective knowledge of this community to choose the best direction. Perhaps there is a better path that I could take? By concatenate, I mean to join together in sequence to create a new audio file from the "concatenated files."

• how to get the latitude or longitude in HTML 5

  - by steven spielberg

  few month ago i write something to get the latitude or longitude from google API. latter i get the database from drupal for latitude or longitude to most of city in worlds. but the problem is that the same city name can be found two or more times in a area. like Firozabad in India and bangladesh both. Agra in UP and agar in Rajasthan. means the confusion in name by user if they found two city by same name they are confused. i hear that HTML 5 support latitude or longitude of the visiter but i need latitude or longitude where they are born or city they want to use to fill a form. how i can get the latitude or longtiude from API like google and some other. the process is that: user put the location in textbox for getting their latitude or longitude. for right thing i want to show them all location [if same thing found more then one]. they can choose the right location and after click they can get the lati and langitude. how i can do this using any API.
