  • Looping HTML5 audio on the iPhone

    - by Peeps
    I'm trying to make a HTML5 webapp that simply plays a sound over and over and over again, on my iPhone. I don't know any Obj-C to do it natively. What I have works fine, but the sound only plays once: <!DOCTYPE html> <html> <head> <title>noisemaker!</title> <meta http-equiv="content-type" content="text/html; charset=utf-8" /> <meta name="viewport" content="maximum-scale=1, minimum-scale=1, width=device-width, user-scalable=no" /> <meta name="apple-mobile-web-app-capable" content="yes" /> </head> <body> <audio src="noise.mp3" autoplay controls loop></audio> </body> </html> Is there a way to either bypass the QuickTime audio screen and loop it in the webpage, or get the QuickTime audio screen to loop the sound?

  • Playing Multiple sounds at the same time in Android

    - by Wrapper
    I am unable to use the following to code to play multiple sounds/beeps simultaneously. In my onclicklistener I have added ... public void onClick(View v) { mSoundManager.playSound(1); mSoundManager.playSound(2); } ... But this plays only one sound at a time, sound with index 1 followed by sound with index 2. How can I play atleast 2 sounds simultaneously using this code whenever there is an onClick() event? public class SoundManager { private SoundPool mSoundPool; private HashMap<Integer, Integer> mSoundPoolMap; private AudioManager mAudioManager; private Context mContext; public SoundManager() { } public void initSounds(Context theContext) { mContext = theContext; mSoundPool = new SoundPool(4, AudioManager.STREAM_MUSIC, 0); mSoundPoolMap = new HashMap<Integer, Integer>(); mAudioManager = (AudioManager)mContext.getSystemService(Context.AUDIO_SERVICE); } public void addSound(int Index,int SoundID) { mSoundPoolMap.put(1, mSoundPool.load(mContext, SoundID, 1)); } public void playSound(int index) { int streamVolume = mAudioManager.getStreamVolume(AudioManager.STREAM_MUSIC); mSoundPool.play(mSoundPoolMap.get(index), streamVolume, streamVolume, 1, 0, 1f); } public void playLoopedSound(int index) { int streamVolume = mAudioManager.getStreamVolume(AudioManager.STREAM_MUSIC); mSoundPool.play(mSoundPoolMap.get(index), streamVolume, streamVolume, 1, -1, 1f); } }

  • Javascript force GC collection? / Forcefully free object?

    - by plash
    I have a js function for playing any given sound using the Audio interface (creating a new instance for every call). This works quite well, until about the 32nd call (sometimes less). This issue is directly related to the release of the Audio instance. I know this because I've allowed time for the GC in Chromium to run and it will allow me to play another 32 or so sounds again. Here's an example of what I'm doing: <html><head> <script language="javascript"> function playSound(url) { snd = new Audio(url); snd.play(); delete snd; snd = null; } </script> </head> <body> <a href="#" onclick="playSound('blah.mp3');">Play sound</a> </body></html> I also have this, which works well for pages that have less than 32 playSound calls: var AudioPlayer = { cache: {}, play: function(url) { if (!AudioPlayer.cache[url]) AudioPlayer.cache[url] = new Audio(url); AudioPlayer.cache[url].play(); } }; But this will not work for what I want to do (dynamically replace a div with other content (from separate files), which have even more sounds on them - 1. memory usage would easily skyrocket, 2. many sounds will never play). I need a way to release the sound immediately. Is it possible to do this? I have found no free/close/unload method for the Audio interface. The pages will be viewed locally, so the constant loading of sounds is not a big factor at all (and most sounds are rather short).

  • Serial: write() throttling?

    - by damian
    Hi everyone, I'm working on a project sending serial data to control animation of LED lights, which need to stay in sync with a sound engine. There seems to be a large serial write buffer (OSX (POSIX) + FTDI chipset usb serial device), so without manually restricting the transmission rate, the animation system can get several seconds ahead of the serial transmission. Currently I'm manually restricting the serial write speed to the baudrate (8N1 = 10 bytes serial frame per 8 bytes data, 19200 bps serial - 1920 bytes per second max), but I am having a problem with the sound drifting out of sync over time - it starts fine, but after 10 minutes there's a noticeable (100ms+) lag between the sound and the lights. This is the code that's restricting the serial write speed (called once per animation frame, 'elapsed' is the duration of the current frame, 'baudrate' is the bps (19200)): void BufferedSerial::update( float elapsed ) { baud_timer += elapsed; if ( bytes_written > 1024 ) { // maintain baudrate float time_should_have_taken = (float(bytes_written)*10)/float(baudrate); float time_actually_took = baud_timer; // sleep if we have > 20ms lag between serial transmit and our write calls if ( time_should_have_taken-time_actually_took > 0.02f ) { float sleep_time = time_should_have_taken - time_actually_took; int sleep_time_us = sleep_time*1000.0f*1000.0f; //printf("BufferedSerial::update sleeping %i ms\n", sleep_time_us/1000 ); delayUs( sleep_time_us ); // subtract 128 bytes bytes_written -= 128; // subtract the time it should have taken to write 128 bytes baud_timer -= (float(128)*10)/float(baudrate); } } } Clearly there's something wrong, somewhere. A much better approach would be to be able to determine the number of bytes currently in the transmit queue, and try and keep that below a fixed threshold. Any advice appreciated.

  • file_field is not sticky in my Rails form

    - by Tony
    I have a pretty standard Rails form: <div> <h1>Create a New Listing</h1> <%- form_for @listing, :html => {:multipart => true} do |f| -%> <div><%= f.label :title, "Title:"%> <%= f.text_field :title %></div> <div> <%= f.label :image, "Image:" %> <%= f.file_field :image </div> <div> <%= f.label :sound, "Sound Clip:"%> <%= f.file_field :sound %><br /> </div> <div class="submit"><%= f.submit 'Post Listing' %></div> <%- end -%> </div> When a user chooses a file, but the form fails for validation purposes, he must always re-select the file. It is not sticky. Any suggestion on how to fix this? Thanks!

  • How to play simultaneous multiply audio sources in Silverlight

    - by Shurup
    I want to play simultaneous multiply audio sources in Silverlight. So I've created a prototype in Silverlight 4 that should play a two mp3 files containing the same ticks sound with an intervall 1 second. So these files must be sounded as one sound if they will be played together with any whole second offsets (0 and 1, 0 and 2, 1 and 1 seconds, etc.) I my prototype I use two MediaElement (me and me2) objects. DateTime startTime; private void Play_Clicked(object sender, RoutedEventArgs e) { me.SetSource(new FileStream(file1), FileMode.Open))); me2.SetSource(new FileStream(file2), FileMode.Open))); var timer = new DispatcherTimer { Interval = TimeSpan.FromMilliseconds(1) }; timer.Tick += RefreshData; timer.Start(); } First file should be played at 00:00 sec. and the second in 00:02 second. void RefreshData(object sender, EventArgs e) { if(me.CurrentState != MediaElementState.Playing) { startTime = DateTime.Now; me.Play(); return; } var elapsed = DateTime.Now - startTime; if(me2.CurrentState != MediaElementState.Playing && elapsed >= TimeSpan.FromSeconds(2)) { me2.Play(); ((DispatcherTimer)sender).Stop(); } } The tracks played every time different and not simultaneous as they should (as one sound).

  • Web Audio API and mobile browsers

    - by Michael
    I've run into a problem while implementing sound and music into an HTML game that I'm building. I'm using the Web Audio API, loading all the sound files with XMLHttpRequests and decoding them into an AudioBufferSourceNode with AudioContext.prototype.decodeAudioData(). It looks something like this: var request = new XMLHttpRequest(); request.open("GET", "soundfile.ogg", true); request.responseType = "arraybuffer"; request.onload = function() { context.decodeAudioData(request.response) } request.send(); Everything plays fine, but on mobile the decodeAudioData takes an absurdly long time for the background music. I then tried using AudioContext.prototype.createMediaElementSource() to load the music from an HTML Audio object, since they support streaming and don't have to load the whole file into memory at once. It looked something like this: var audio = new Audio('soundfile.ogg'); var source = context.createMediaElementSource(audio); var mainVolume = context.createGain(); source.connect(mainVolume); mainVolume.connect(context.destination); This loads much faster, but the audio volume isn't affected by the gain node. Works fine on desktop, so I'm assuming this is a bug/limitation of mobile Chrome (testing on Android). Is there actually no good, well-performing way to handle sound on mobile browsers or am just I doing something stupid?

  • Playing a sequence of sounds without gaps (iPhone)

    - by Fiire
    I thought maybe the fastest way was to go with Sound Services. It is quite efficient, but I need to play sounds in a sequence, not overlapped. Therefore I used a callback method to check when the sound has finished. This cycle produces around 0.3 seconds in lag. I know this sounds very strict, but it is basically the main axis of the program. EDIT: I now tried using AVAudioPlayer, but I can't play sounds in a sequence without using audioPlayerDidFinishPlaying since that would put me in the same situation as with the callback method of SoundServices. EDIT2: I think that if I could somehow get to join the parts of the sounds I want to play into a large file, I could get the whole audio file to sound continuously. EDIT3: I thought this would work, but the audio overlaps: waitTime = player.deviceCurrentTime; for (int k = 0; k < [colores count]; k++) { player.currentTime = 0; [player playAtTime:waitTime]; waitTime += player.duration; } Thanks

  • Ubuntu 10.04 preseed unattended install results in faulty partition table

    - by joschi
    I'm currently trying to set up an unattended installation of Ubuntu 10.04 (Lucid Lynx) through preseeding. But whenever I try to create a custom partition scheme, the Debian installer (which Ubuntu is using) produces a faulty partition table. I've taken the partition scheme described in the example preseed file: d-i partman-auto/expert_recipe string \ boot-root :: \ 40 50 100 ext3 \ $primary{ } $bootable{ } \ method{ format } format{ } \ use_filesystem{ } filesystem{ ext3 } \ mountpoint{ /boot } \ . \ 500 10000 1000000000 ext3 \ method{ format } format{ } \ use_filesystem{ } filesystem{ ext3 } \ mountpoint{ / } \ . \ 64 512 300% linux-swap \ method{ swap } format{ } \ . Unfortunately it also produces an incorrect partition table on the disk. The installation process itself is working and the installed system eventually boots and is working, as far as I can tell. But fdisk and cfdisk are still complaining: # fdisk -l /dev/sda Disk /dev/sda: 17.2 GB, 17179869184 bytes 255 heads, 63 sectors/track, 2088 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x000a1cdd Device Boot Start End Blocks Id System /dev/sda1 * 1 5 37888 83 Linux Partition 1 does not end on cylinder boundary. /dev/sda2 5 2089 16736257 5 Extended /dev/sda5 5 2013 16121856 83 Linux /dev/sda6 2013 2089 613376 82 Linux swap / Solaris cfdisk even refuses to start at all: # cfdisk /dev/sda FATAL ERROR: Bad primary partition 1: Partition ends in the final partial cylinder parted on the other hand does not complain about the cylinder boundary of /dev/sda1: # parted /dev/sda p Model: VMware Virtual disk (scsi) Disk /dev/sda: 17.2GB Sector size (logical/physical): 512B/512B Partition Table: msdos Number Start End Size Type File system Flags 1 1049kB 39.8MB 38.8MB primary ext4 boot 2 40.9MB 17.2GB 17.1GB extended 5 40.9MB 16.5GB 16.5GB logical ext4 6 16.6GB 17.2GB 628MB logical linux-swap(v1) Since the installed system is working, it shouldn't be a big problem but I'm afraid that this will mean trouble in the future.

  • Switch Windows 8 from a hybrid MBR/GPT => GPT only on Macbook Pro Retina

    - by Sid
    I used DiskUtility+Bootcamp Wizard to setup my hard drive for Windows 8 (final MSDN). Somewhere in that process, the Apple tools turned my GPT disk into a hybrid MBR/GPT. All my 4 primary MBR partitions are used up, so when I try turning on Bitlocker in Windows 8, it complains about not finding a System drive. I know on Windows 8 the Bitlocker setup tries to create the 200(?)MB system partition if it's missing. However with all 4 partitions filled I suspect it can't create system drive = it can't find it = throws back an error like "BitLocker Setup could not find a target system drive. You may need to manually prepare your drive for BitLocker". I've already tried disabling hibernation, swap file etc. Now I'm thinking that if I were to get rid of the MBR scheme altogether, perhaps I can be alright within the GPT world without MBR's 4 primary partitions limit. So, how can I get rid of the MBR tables on the hybrid scheme in a manner that still leaves Mac OS and Windows 8 in working conditions? Details: Hardware is the MacbookPro Retina. Primary MBR partitions are consumed as follows: EFI partition HFS+ partition (=encrypted, therefore ="Apple_CoreStorage") HFS+ partition (Recovery partition, contains unencrypted Mac bootloader) NTFS partition (Windows8 all-in-one partition) diskutil list output sid-mbpr:~ sid$ diskutil list /dev/disk0 #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *251.0 GB disk0 1: EFI 209.7 MB disk0s1 2: Apple_CoreStorage 160.0 GB disk0s2 3: Apple_Boot Recovery HD 650.0 MB disk0s3 4: Microsoft Basic Data Win8 90.1 GB disk0s4 GPT vs MBR addresses sid-mbpr:~ sid$ sudo gptsync /dev/rdisk0 Password: Current GPT partition table: # Start LBA End LBA Type 1 40 409639 EFI System (FAT) 2 409640 312909639 Unknown 3 312909640 314179175 Mac OS X Boot 4 314179584 490233855 Basic Data Current MBR partition table: # A Start LBA End LBA Type 1 1 409639 ee EFI Protective 2 409640 312909639 ac Apple RAID 3 312909640 314179175 ab Mac OS X Boot 4 * 314179584 490233855 07 NTFS/HPFS Status: GPT partition of type 'Unknown' found, will not touch this disk.** **: Ignore this message, the gptsync tool is old and doesn't understand the UUID for "Apple_CoreStorage" / FileVault2 partitions.

  • Getting a "403 access denied" error instead of serving file (using django, gunicorn nginx)

    - by Finglish
    Getting a "403 access denied" error instead of serving file (using django, gunicorn nginx) I am attempting to use nginx to serve private files from django. For X-Access-Redirect settings I followed the following guide http://www.chicagodjango.com/blog/permission-based-file-serving/ Here is my site config file (/etc/nginx/site-available/sitename): server { listen 80; listen 443 default_server ssl; server_name localhost; client_max_body_size 50M; ssl_certificate /home/user/site.crt; ssl_certificate_key /home/user/site.key; access_log /home/user/nginx/access.log; error_log /home/user/nginx/error.log; location / { access_log /home/user/gunicorn/access.log; error_log /home/user/gunicorn/error.log; alias /path_to/app; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $http_host; proxy_redirect off; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Scheme $scheme; proxy_pass http://127.0.0.1:8000; proxy_connect_timeout 100s; proxy_send_timeout 100s; proxy_read_timeout 100s; } location /protected/ { internal; alias /home/user/protected; } } I then tried using the following in my django view to test the download: response = HttpResponse() response['Content-Type'] = "application/zip" response['X-Accel-Redirect'] = '/protected/test.zip' return response but instead of the file download I get: 403 Forbidden nginx/1.1.19 Please note: I have removed all the personal data from the the config file, so if there are any obvious mistakes not related to my error that is probably why.

  • Configuring https access on HP A5120 Switch

    - by GerryEgan
    I am trying to configure HTTPS management on a HP a5120 switch running Version 5.20.99, Release 2215 and not having much luck. I have followed the manual by creating an SSL policy first and then enabling the HTTPS server with the SSL policy: ssl server-policy sslpol ip https ssl-server-policy sslpol ip https enable When I try and log onto the switch with Google Chrome I get the following error: Error 107 (net::ERR_SSL_PROTOCOL_ERROR): SSL protocol error. When I look this up I have found references to errors due to TLS being used in SSL. I can find no way to specify the SSL version in the server policy. The manual has a configuration example that uses MSCEP to retrieve a certificate but in Windows 2008 R2 that feature is only available in Enterprise and Datacentre editions which I don't have. I have SSH configured and it is using a locally generated certificate so I'm not sure if I can use that but I'd like to if possible. Has anybody been able to setup HTTPS management on HP A series switches without MSCEP? Any and all help appreciated! here is a copy of my config with the interfaces removed: version 5.20.99, Release 2215 # sysname MYSYSNAME # irf domain 10 irf mac-address persistent timer irf auto-update enable undo irf link-delay # domain default enable system # telnet server enable # vlan 1 # vlan 100 description Management # radius scheme system primary authentication 127.0.0.1 1645 primary accounting 127.0.0.1 1646 user-name-format without-domain # domain system access-limit disable state active idle-cut disable self-service-url disable # user-group system group-attribute allow-guest # local-user admin password cipher authorization-attribute level 3 service-type ssh telnet terminal service-type web # stp enable # ssl server-policy sslpol pki-domain MYDOMAIN # interface NULL0 # interface Vlan-interface199 ip address 192.168.199.140 255.255.255.0 # interface GigabitEthernet1/0/1 poe enable stp edged-port enable # interface Ten-GigabitEthernet2/1/2 # dhcp-snooping # ntp-service unicast-server 192.168.1.71 # ssh server enable # ip https ssl-server-policy sslpol ip https enable # load xml-configuration # user-interface aux 0 1 user-interface vty 0 15 authentication-mode scheme

  • Is my webserver being abused for banking fraud?

    - by koffie
    Since a few weeks i'm getting a lot of 403 errors from apache in my log files that seem to be related to a bank frauding scheme.

I suspect not, because it's giving 403 to all requests. But any extra checks that I can do to ensure that my server is not being abused are welcome. I'm also curious on how the "bad guys" expected my server to behave. I.e. are they just expecting my server to act as a proxy to hide the ip of the fake site, or are they expecting that my server will actually serve the fake banking website? Is the ip 1.2.3.4 more likely to be the ip of a victim or the ip of a bad guy. I suspect a bad guy, because it's quite unlikely that a real person would visit 4 bank sites in a second. If it's from a bad guy I'm very curious at what he is trying to do.

  • File uploads and client_max_body_size in nginx + gunicorn + django

    I need to configure nginx + gunicorn to be able to upload files greater than the default max size in both servers. My nginx .conf file looks like this: server { # ... location / { proxy_pass_header Server; proxy_set_header Host $http_host; proxy_redirect off; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Scheme $scheme; proxy_connect_timeout 60; proxy_pass http://localhost:8000/; } } The idea is to allow requests of 20M for two locations: /admin/path/to/upload?param=value /installer/other/path/to/upload?param=value I've tried to add location directives at the same level than the one I've pasted here (getting 404 errors) and also tried to add them inside the location / directive (getting 413 Entity Too Large errors). My location directives look like these in their simplest form: location /admin/path/to/upload/ { client_max_body_size 20M; } location /installer/other/path/to/upload/ { client_max_body_size 20M; } But they don't work (actually I tested lots of combinations and I'm desperate thinking about this. Please, help If you can: What settings do I need to set to make this work? Thank you so much!

  • Nginx and Gunicorn hanging on GET requests

    I'm using Nginx + Gunicorn which is serving my Django project. All GET requests hang for ~1 min.

  • SQL cluster instance names for large project

    - by Sam
    We're setting up two clusters. One dev and one prod. The Production will host two SQL instances - a OLTP and a DW. The development will host 4 OLTP non-production environments and at least one DW non-production. We're working on getting more DW non-prods and possibly more OLTP systems. I'm considering a naming scheme like this, where PROJ would be 3 initials for the project name.

On each server, the instance name, to the right of the slash, must be unique. Any thoughts on this? I'm trying to avoid having instance names drifting from reality as the project progresses - say we change what we call a certain environment or want to repurpose one. Then we can update a listing of the purposes for the instances and be done with it. How has a scheme like this worked out for you? Maybe you do things another way in your shop - tell me about it. Thanks.

  • Redirect 301 fails with a path as destination

    - by Martijn Heemels
    I'm using a large number of Redirect 301's which are suddenly failing on a new webserver. We're in pre-production tests on the new webserver, prior to migrating the sites, but some sites are failing with 500 Internal Server Error. The content, both databases and files, are mirrored from the old to the new server, so we can test if all sites work properly. I traced this problem to mod_alias' Redirect statement, which is used from .htaccess to redirect visitors and search engines from old content to new pages. Apparently the Apache server requires the destination to be a full url, including protocol and hostname. Redirect 301 /directory/ /target/ # Not Valid Redirect 301 /main.html / # Not Valid Redirect 301 /directory/ http://www.example.com/target/ # Valid Redirect 301 /main.html http://www.example.com/ # Valid This contradicts the Apache documentation for Apache 2.2, which states: The new URL should be an absolute URL beginning with a scheme and hostname, but a URL-path beginning with a slash may also be used, in which case the scheme and hostname of the current server will be added. Of course I verified that we're using Apache 2.2 on both the old and the new server. The old server is a Gentoo box with Apache 2.2.11, while the new one is a RHEL 5 box with Apache 2.2.3. The workaround would be to change all paths to full URL's, or to convert the statements to mod_rewrite rules, but I'd prefer the documented behaviour. What are your experiences?

  • Defining Virtual and Real User Directories with Dovecot & Postfix

    - by blankabout
    Following a wobble described in this question we now have virtual and real users authenticating with Dovecot, the problem now is that the real users (who have been on the system for years) can no longer access their mail. I'm guessing that it is because Dovecot is configured to point to the virtual mailboxes but not the real mail boxes. These are snippets from the config files: /etc/dovecot/dovecot.conf !include conf.d/*.conf /etc/dovecot/conf.d/10-auth.cong passdb { driver = passwd-file # Path for passwd-file. Also set the default password scheme. args = scheme=cram-md5 /etc/cram-md5.pwd } userdb { driver=static #args = mail_uid=dovecot mail_gid=dovecot /etc/dovecot/userdb args = uid=vmail gid=vmail home=/var/spool/vhosts/%d/%n /etc/dovecot/userdb } [email protected]:::::/var/spool/vhosts/virtualdomain.com/:/bin/false:: We think the problem is that the Dovecot file 10-auth.conf does not contain a method of accessing the mailboxes for the real users. We have looked around on this site, dovecot.org and done the usual googling but cannot find anywhere that describes how to set up virtual users on alongside legacy real users. Any help would be appreciated, especially by our real users who would like the contents of their inboxes to be available! If any further config is required, please let me know.

  • Lighttpd + django on gentoo 10 seconds to answer

    - by plaetzchen
    I want to run a Django site on a lighttpd with fastcgi on a gentoo machine. Everytime I try to access the site I get a response after more or less exactly 10 seconds. Im using a socket to let lighttpd communicate with my Django site, but a tcp port doesn't help either. Could this be a lighttpd problem? I tried to both from a server in the internet as well as from localost, this is what lighttpd gives me in the error.log 2012-07-10 14:36:36: (response.c.300) -- splitting Request-URI 2012-07-10 14:36:36: (response.c.301) Request-URI : / 2012-07-10 14:36:36: (response.c.302) URI-scheme : http 2012-07-10 14:36:36: (response.c.303) URI-authority: owntube 2012-07-10 14:36:36: (response.c.304) URI-path : / 2012-07-10 14:36:36: (response.c.305) URI-query : 2012-07-10 14:36:36: (response.c.300) -- splitting Request-URI 2012-07-10 14:36:36: (response.c.301) Request-URI : /owntube.fcgi/ 2012-07-10 14:36:36: (response.c.302) URI-scheme : http 2012-07-10 14:36:36: (response.c.303) URI-authority: owntube 2012-07-10 14:36:36: (response.c.304) URI-path : /owntube.fcgi/ 2012-07-10 14:36:36: (response.c.305) URI-query : 2012-07-10 14:36:36: (response.c.349) -- sanatising URI 2012-07-10 14:36:36: (response.c.350) URI-path : /owntube.fcgi/ 2012-07-10 14:36:36: (mod_access.c.135) -- mod_access_uri_handler called 2012-07-10 14:36:36: (mod_fastcgi.c.3632) handling it in mod_fastcgi 2012-07-10 14:36:36: (response.c.470) -- before doc_root 2012-07-10 14:36:36: (response.c.471) Doc-Root : /var/www/owntube 2012-07-10 14:36:36: (response.c.472) Rel-Path : /owntube.fcgi 2012-07-10 14:36:36: (response.c.473) Path : 2012-07-10 14:36:36: (response.c.521) -- after doc_root 2012-07-10 14:36:36: (response.c.522) Doc-Root : /var/www/owntube 2012-07-10 14:36:36: (response.c.523) Rel-Path : /owntube.fcgi 2012-07-10 14:36:36: (response.c.524) Path : /var/www/owntube/owntube.fcgi 2012-07-10 14:36:36: (response.c.541) -- logical -> physical 2012-07-10 14:36:36: (response.c.542) Doc-Root : /var/www/owntube 2012-07-10 14:36:36: (response.c.543) Rel-Path : /owntube.fcgi 2012-07-10 14:36:36: (response.c.544) Path : /var/www/owntube/owntube.fcgi

  • How can I setup nginx to serve virtualhosts with rails(unicorn/passenger) and php-fpm

    - by NewAlexandria
    I would like to serve multiple sites on one instance. I install nginx, php-fpm, and a rails app. I use sites like this to guide me. I configure php-fpm to listen to a local socket listen = /var/run/php-fpm/php-fpm.sock I configure ngnix with multiple hosts: include /etc/nginx/conf.d/*.conf I have several site php conf files like /etc/nginx/conf.d/site1.conf server { listen 80; server_name site1.com www.site1.com; root /var/www/site1; location / { index index.html index.php; } location ~ \.php$ { fastcgi_pass unix:/var/run/php-fpm/php-fpm.sock; fastcgi_index index.php; include fastcgi_params; fastcgi_param PATH_INFO $fastcgi_script_name; fastcgi_param SCRIPT_FILENAME $document_root/$fastcgi_script_name; } } and rails site conf files like upstream rails { server 127.0.0.1:3000; } server { listen 80; server_name site2.com www.site2.com; root /var/www/site2; location / { proxy_pass http://rails; proxy_set_header X-Forwarded-For $remote_addr; proxy_set_header Host $host; proxy_set_header X-Url-Scheme $scheme; } } I have a unicorn rails server running via rails s -p 3000 Yet, no sites come up for either site1.com or site2.com. I can get to the rails site at www.site2.com:3000 What is wrong? I've spent 2 days (nearly 30hr) trying many different blogs, SO / SF questions, etc. Please share your insight or answer. edit 1: No log entries are created when I try to visit either site. It's like the requests never come in.

  • Cloning to a smaller hard drive with DDRescue

    - by krebshack
    I am currently working with a 700 GB Seagate hard drive that's beginning to fail. I'll call this "SDB" from now on. I'd like to clone it while I'm still able to. However, the only hard drive that I have available is a 500 GB WD hard drive. I'll call this "SDC" from now on. The partition scheme on SDB is as follows: 9.77 GB is allocated to a recovery partition and the remaining 688.87 GB is allocated to a Windows partition. Both are formatted using NTFS. There is no partition scheme on SDC. I know how to clone one hard drive to another using DDRescue but I've only done it using hard drives that are the same size. For your reference, I'll normally use the command "ddrescue -v -r 3 /dev/sdb /dev/sdc example.log". I'd like to know if it's possible to do this with DDRescue. I've read the manual from GNU (http://www.gnu.org/software/ddrescue/manual/ddrescue_manual.html) and I haven't seen anything indicating that it is possible. I'm just looking for some confirmation that this is a correct impression. If it's not possible, then it would be helpful if any of y'all would be able to make some work around suggestions. But please don't feel obligated to do that. I don't want to have my one thread bogged down with two many questions.
