• How to delete a folder in python when [Error 32] is present

  - by harish

  I am using python 2.7. I want to delete a folder which may or may not be empty. The folder is handled by thread for file-monitoring. I am not able to kill thread but wanted to delete this folder any how. I tried with os.rmdir(Location) shutil.rmtree(Location) os.unlink(Location) But, it didn't work. It is showing error as [Error 32] The process cannot access the file because it is being used by another process: 'c:\\users\\cipher~1\\appdata\\local\\temp\\fis\\a0c433973524de528420bbd56f8ede609e6ea700' I want to delete folder a0c433973524de528420bbd56f8ede609e6ea700 or delete whole path will also suffice.

• URI Rewrite with fake subdomains and multiple variables

  - by Rich

  Can someone please help with trying to use mod rewrite so foo.domain.com is rewritten to domain.com/p.php?s=foo and foo.domain.com/bar to domain.com/p.php?s=foo&p=bar? Currently my .htaccess is: RewriteEngine On # Remove www RewriteCond %{HTTP_HOST} ^www.domain.com$ [NC] RewriteRule ^(.*)$ http://domain.com/$1 [R=301,L] # Rewrite subdomain etc. RewriteCond %{HTTP_HOST} ^(.*)\.domain\.com$ [NC] RewriteRule ^([^/]+)/?$ p.php?s=%1&p=$2 [QSA,L,NC] But I can't work out how to grab the second variable (being optional and after a slash at the end of the URI. I've tried changing the end of the condition to ?/(.*)$, but to no avail and my mod rewrite skills are certainly naff!

• FFmpeg add multiple audio files to video at specific points

  - by Arran

  I have two audio files, each about 3 minutes long. I want to take the first 10 seconds of each file and add them each to a video file at specific points - 0 seconds and 10 seconds. So the resulting video should be 20 seconds long. I've got this far: ffmpeg -i video.mov -ss 0 -t 20 -itsoffset 0 -i audio1.mp3 -itsoffset 10 -i audio2.mp3 -acodec copy -vcodec copy out.mov ...but the resulting video has 20 seconds of the first audio file only, the second audio file doesn't start at 10 seconds like it should. Any help would be appreciated, thanks!

• Multiple wifi cards and Internet connections on Win-7

  - by Dpp

  Hello, I have two wifi cards and two separated internet connections. I connect to the Internet with both of them but one does all of the internet transactions (and I have not seen any place where I can specify which one I would prefer to use!) What I would like to do is use one of them for the browser and skype only, and the other one for stock exchange software for instance. Any idea if it is possible?

• Multiple network interfaces and UDP packets distribution

  - by Robert Kubrick

  I have a Linux server with 2 1Gb network interfaces eth1 and eth2. If I start 2 clients listening to the same multicast address and each client connects through a different NIC (say client 1 listens to the multicast through eth1 and client 2 through eth2), then client 2 gets duplicate UDP packets. If both clients use the same interface eth1 on the other hand, both clients work fine. I have already tried to set arp_filter and proxy_arp to 1 (arp flux issue) but it hasn't solved the issue. Is this a Linux kernel problem? Or is there another way to setup the interfaces correctly?

• Multiple SSL certificates on one server

  - by Kyle O'Brien

  We're hosting two websites on our fairly tiny but dedicated production server. Both website require SSL authentication. So, we have virtualhosts set up for both of them. They both reference their own domain.key, domain.crt and domain.intermediate.crt files. Each CSR and certificate file for each site was setup using its own unique information and nothing is shared between them (other than the server itself) However, which ever site's symbolic link (set up in /etc/apache2/sites-enabled) is reference first, is the site who's certificate is referenced even if we're visiting the second site. So for example, assume our companies are Cadbury and Nestle. We set up both sites with their own certificates but we create Cadbury's symbolic link in apache's site-enabled folder first and then Nestle's. You can visit Nestle perfectly fine but if you check the certificate installation, it reference's Cadbury's certificate. We're hosting these websites on a dedicated Ubuntu 12.04.3 LTS server. Both certificates are provided by Thawte.com. I came across a few potential solutions with no degree of success. I'm hoping someone else has a decent solution? Thanks Edit: The only other solution that seems to have provided success to some people is using SNI with Apache. However, the setups here didn't seem to coincide with our setup at all.

• Passwordless ssh on multiple machines

  - by Phil

  Hi all, I'm quite confused with all the ssh security stuff. I am trying to reconfigure a system that is currently broken for reasons unknown. Machine A is your personal computer that you use whenever you're at home. Machine B is the head node of an HPC cluster and all the other machines C are all identically configured machines which share the home directories of machine B. This is an HPC cluster if you haven't guessed. How would I configure passwordless ssh between any nodes B or C. A can only get to C through sshing into B

• mysql is not using multiple cpus

  - by helpmhost

  Hi, Our MySQL server has been using a lot of CPU lately (it's reached 100% several times and stays there for a while) and I noticed that it the CPU load is all on one core of one cpu. I was hoping to spread that out to all 4 on my server. I have been tweaking the MySQL settings to use more ram and less cpu, but it still occasionally reaches very high CPU usage. It seems like everything about the topic refers to thread_concurrency (which I've read is a solaris only setting). What can I do in Linux? Thanks.

• Successfully concatenating multiple videos

  - by wiseguydigital

  My mission is to create videos out of old web slideshows. To start with I have jpegs and audio files that worked as Flash slideshows in an old system, structured such as this: Audio structure my_audio_1.mp3 (this file is a 3 second mp3 of silence) my_audio_2.mp3 my_audio_3.mp3 my_audio_4 etc... roughly 30 mp3s per slideshow Image structure my_image_1.jpg (this acts as the opening slide) my_image_2.jpg my_image_3.jpg my_image_4. etc... roughly 30 images per slideshow. As there are almost 100 slideshows that must be converted to video, I have created a web-based interface using PHP to automate the process, that sits on a local system and attempts to combine the files using shell_exec(). The process uses the following workflow: Loop through each slide and make an avi or mpeg. So for instance my_mini_video_2.avi would be a video that consists of my_image_2.jpg and has a soundtrack of my_audio_2.mp3. This slide would last the length of my_audio_2.mp3. Join / stitch / concat all of the mini videos to create the final video (Using a combination of cat and either mencoder or ffmpeg (I have also tried avimerge but to no avail). Transcode the new 'master' video to various formats such as flv etc. I thought this would be simple and have been close on many occasions but it still won't work. I can't get past stage 2 as I can't get a perfect 'master' video. I have now experimented with Mencoder, FFMpeg and seem to have been through every combination I can think of. The problem is that the audio and visuals never sync, no matter what I try. Also, I have even tried created audio-less mini videos, joining the MP3s into one long MP3 using both cat and mp3wrap and then assigning the new long MP3 as the audio track, but this always produces either a very short file or a badly slowed down file and makes the female voiceover sound like a male boxer!!! There appears to be no problems at all with the original files. Does anybody have any experience in producing a video successfully from the same kind of starting point? Or any ideas on what I may be doing wrong? As an example: If I create silent mini-videos, and stitch them together into 'temp-master.mpg' and then join the MP3s together into single MP3 called 'temp-master-audio.mp3', the audio file's duration is 09:10 and the video file's duration is 08:35. They should be the same and the audio will seem sloooow. I haven't posted code as I have written lots and lots of combinations.

  Hi at all, I have some problem with multiple screen support, I work with dp(dpi) for specify the layout_heigth and layout_width and I hope that is the better way to support multiple screen, but when I tried with two smartphone I meet two different result. I give an example, this is a layout I use: <?xml version="1.0" encoding="UTF-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/cities_main_layout" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> <ListView android:id="@+id/citieslist" android:layout_width="wrap_content" android:layout_height="320dip" android:layout_gravity="center_vertical" android:layout_below="@id/cities_main_layout" /> <LinearLayout android:id="@+id/cities_button_layout" android:orientation="horizontal" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_below="@id/citieslist" android:layout_gravity="center_vertical"> <Button android:id="@+id/bycountry" android:layout_height="50dip" android:layout_width="105dip" android:background="@drawable/buttonmarket" android:text="@string/button_bycountry" /> <Button android:id="@+id/top10" android:layout_height="50dip" android:layout_width="105dip" android:background="@drawable/buttonmarket" android:text="@string/button_top10" /> <Button android:id="@+id/recommended" android:layout_height="50dip" android:layout_width="105dip" android:background="@drawable/buttonmarket" android:text="@string/button_recommended" /> </LinearLayout> </RelativeLayout> The button are at the bottom of the layout, and I see two different result: In the last smartphone I can see the buttons, instead in the first I cannot...what's wrong? I have to write a layout for any set of screen??!!!

• Error while closing SQL Connection

  - by Wickedman84

  I have a problem with closing the SQLconnection in my application. My application is in VB.net. I have a reference in my application to a class with code to open and close the database connection and to execute all sql scripts. The error occurs when i close my application. In the formClosing event of my main form I call a function that closes all the connections. But just before I close the connections I perform an SQLquery to delete a row from a table with the function below. Public Function DeleteFunction(ByVal mySQLQuery As String, ByVal cmd As SqlCommand) As Boolean Try cmd.Connection = myConnection cmd.CommandText = mySQLQuery cmd.ExecuteNonQuery() Return True Catch ex As Exception WriteErrorMessage("DeleteFunction", ex, Logpath, "SQL Error: " & mySQLQuery) Return False End Try End Function In my application I check the result of the boolean. If it returns True, then i call the function to close the database connection. The returned boolean is True and the requested row is deleted in my database. This means i can close my connection which I do with the function below. Public Sub DatabaseConnClose() myCommand.CommandText = "" myConnection.Close() myCommand = Nothing myConnection = Nothing End Sub After executing this code I receive an error in my logfile from the DeleteFunction. It says: "Connection property has not been initialized." It seems very strange to receive an error from a function that was completely executed, or am i wrong to think that? Can anyone tell me why I receive this error and how I can solve the problem?

• Upstart multiple instances of service not working.

  - by Dax

  I started playing with MongoDB on Lucid. Now I would like to run a DB and Config server on the same box. They both use the same binary to launch, but with different config files and running on different ports. All directories for log and lib is split so one goes to mongodb and the other to mongoconf. Each process can be started without any problems on their own. start mongodb stop mongodb start mongoconf stop mongoconf But if I try to start both, the second one would just start and exit. Using 'initctl log-priority debug' I got the following in the logs. Jan 6 12:44:12 mongo4 init: event_finished: Finished started event Jan 6 12:44:12 mongo4 init: job_process_handler: Ignored event 1 (1) for process 5690 Jan 6 12:44:12 mongo4 init: mongoconf (mongoconf) main process (5690) terminated with status 1 Jan 6 12:44:12 mongo4 init: mongoconf (mongoconf) goal changed from start to stop Jan 6 12:44:12 mongo4 init: mongoconf (mongoconf) state changed from running to stopping man 5 init shows that you can use instance names to differentiate the two. I tried using 'instance mongoconf' in the on upstart script and 'instance mongodb' in the other one, and it still fails. I can manually start the other process, so there is definitely no conflicts on port numbers or directories. Any ideas on what to try or how to get output on why it is 'terminated with status 1'? Thanx

• Running multiple versions of PostgreSQL on the same Ubuntu server

  - by user51938

  I have PostgreSQL 8.4 and 9.0 running on the same server (Ubuntu Lucid). I installed them both via apt-get (8.4 with the default package sources, and 9.0 after adding the ppa from https://launchpad.net/~pitti/+archive/postgresql). When I run a command like "createdb" from the command line or start up the "psql" shell, PostgreSQL version 8.4 is used by default on my system. So, how do I force these commands to use PostgreSQL 9.0 instead of 8.4?

• Handler not yet determined error

  - by SourceC

  Hello, I don’t know anything about deploying a website, so I probably made some stupid mistake. Anyways, I opened IIS 7 manager, created new virtual directory ( via Add Application ) and pointed it to physical directory where Visual studio saved my Web project. But when I tried to request an .aspx page, browser reported the following error (I won’t post the whole error, but just the interesting bits): Handler: Not yet determined Config Error: Cannot read configuration file due to insufficient permissions Logon User: Not yet determined A) why is handler not yet determined? As far as I know, IIS7 does have Asp.Net handler registered?! B) Why wouldn’t IIS have sufficient permissions? Does that mean I should give IIS higher privileges? Or does Asp.Net runtime have insufficient permissions? C) Could the error also be due to the fact that perhaps it expected the user to authenticate itself? I’m assuming this due to Logon user not yet being determined? D) And finally, any ideas how to make it work? thanx

• Availability of big files on multiple servers

  - by Imises

  I have to handle many (1'000 - 30'000) big files ranging from 200MB up to 2GB. The demand for these files is variable (0 - 300 downloads / file). This is why a single file must saved on 2 or more servers. My servers are placed in different datacenters (France), with different size HDDs (750GB to 4TB). Currently I share the files using PHP and ncftpget / ncftpput, but it's very slow. I need a solution to handle balancing these files across 7+ servers.

• How to enable WordPress to have multiple sites without a re-direct

  - by user57039

  I'm using WordPress to manage my site and when the site does a re-direct, it slows down performance. For example, WordPress allows you a single default site, www.mycompany.com. If a user goes to mycompany.com, WP will re-direct it www.mycompany.com. Is there a way to configure WP so that it will listen on both www.mycompany.com and mycompany.com without redirects. The redirects are causing performance hits to the site.
