  • Combine Multiple Audio Files into a single higher-quality audio File

    - by namenlos
    BACKGROUND My team gave a demo to a large audience - we recorded the audio of the demo in multiple locations in the room (3) the audio was recorded using cheap laptop microphones I was not involved in the recording of the audio or the demo Both audio files suck in some form the first one is of a recording near the speaker - which clearly gets his voice but the the audience is audience is muffled - also this one is slightly noisy The second recording was done in the middle of the audience - it gets the audience questions clearly but actually gets the speaker rather sometimes well and sometimes poorly (not all the speakers spoke loudly enough to be heard) MY QUESTION Is there any techinque or software which can be used to merge these audio files in such a way that the best qualities of each are preserved. I am NOT asking now to simply merge them together in one track - I've already done that in Audacity and it is certainly better - what I am looking for could be considered closer to how HDR images are created - multiple exposures combined into an enhanced new version which is not simply an average of the inputs. NOTE Am not an "Audio" guy - just a normal user

  • Unmounting a zfs pool while it is shared with sharenfs

    - by Ted W.
    I have a Solaris (open indiana) system which is getting poor disk write performance. In order to enable ZIL in this version of zfs I need to add a line to /etc/system. This will not take affect until I've unmounted and remounted the zpool. The trick is that this spool is shared via nfs to about 200 other servers to host users' home directories. I can guarantee that no users will be accessing the disks during this period of maintenance but I would like to avoid having to issue an unmount for 200 systems in order to unmount the disk on the Solaris box. My question is, with sharenfs, is it necessary to have all systems disconnected before unmounting the filesystem on the host? If it's possible, how do you go about it? I've tried unmounting already, the normal way, and it reports the disk is busy. There is no lsof in Solaris and pfiles (I think that's what it was) does not show anything obviously using the mounts.

  • httpd memory could not be written on winxp

  • Move MySQL database while instance is online

    - by Mike Scott
    I have a MySQL instance containing a number of databases, one of which is an archive database (although using the INNODB rather than ARCHIVE storage engine) that is not queried or written to in normal operation. The data filesystem is filling up and I'd like to move the archive database's data directory to a different filesystem (and then symlink it back, obviously). If there are no SQL statements attempting to query or update the data during the move, can I safely do this while the MySQL instance and the other databases stay online and in use? I plan to rsync the database directory to the new filesystem, then rename the old one on the original filesystem to something different and create the new symlink. lsof reports that MySQL does have the .ibd files open, so presumably it would have to reopen them.

  • All my folders and files on my flash drive have been renamed automatically and I can no longer open them... I need those files

    - by jennifer
    I opened up my flash drive this morning and all of my folders and files are normal, except for one folder and all its included files, which is the most important folder. The subfolders and files are renamed with bizarre characters and when I click to open them, a pop-up appears saying it's not accessible and the filename or directory name is incorrect. I don't want to reformat the flash drive because I'd lose all those files. Is there a way for me to restore it or something? I would attach a screen shot, but apparently new users do not have that privilege. If you have a vague idea of what I'm talking about, let me know and I can email you screenshots so you can have a better understanding. Any help is greatly appreciated!

  • Windows Server 2008 hangs up while booting

    - by Jim R
    Windows Server 2008 hangs up while booting after Windows update applied several updates. The server is a virtual instance on a Server 2008 Hyper-V host. Other virtual servers are fine, but have not been updated. The normal boot shows the horizontal barber poll forever. When I do a safe boot it also hangs up. With a "Please Wait..." after loading many '.sys' files. The last successfully loaded file listed is: '\Windows\system32\drivers\crcdisk.sys' That is the extent of what I have been able to determine.

  • Network keeps disconnecting - Repairing solves it. Router configuration

    - by Joao Carlos
    My network connection keeps going insane, it will keep normal applications connected, like TeamViewer and MSN, but webpages will stop loading (Problem loading page). Everything looks connected and works like a charm, but webpages and new connections wont work. If I press "Repair" in the network connections to restart the adapter, it will work. This happens on WIRED and WIRELESS connections, both on Windows and on MacOSx. I have had this for years (different computers, routers, cities), but I never figured it out. I learn to live with it, but, I think theres probably a solution. What must I be doing wrong if this keeps happening? You guys have same thing?

  • Firefox: box mode?

    - by Peter Mortensen
    What is the "box mode" (for a lack of a better word) in Firefox? How can I exit it again? If I hold down the Ctrl key and left click while the cursor is over some element on a page it becomes boxed: Firefox seems to go into some special mode. What is this mode for? How can I go back to normal mode? Installed add-ons in Firefox: BetterPrivacy 1.29, NoScript 1.9.0.6 and SQLite Manager 0.4.7. (Microsoft .NET Framework Assistent 1.0 is disabled.) Platform: Firefox 3.0.6, Windows XP 64 bit SP2, 8 GB RAM.

  • Voices disappear when using headphones.

    - by James
    How do I declare a variable in C? P.S. I have a pair of SteelSeries Siberia headphones. I've noticed that when watching some films the voices are completely silent, yet when I unplug the headset and listen through my speakers they are there and sound normal. I have no other software that could be interfering with it and it happens regardless of the software I use for playback (I've tried VLC, WMP and Quicktime). It is so strange, and it almost sounds deliberate - the rest of the audio is untouched but voices disappear. The films only have single audio tracks, and it doesn't happen with every film. Can anyone give me any hints as to what could possibly cause this? I am stumped!

  • What could cause my LAN Pings be greater than 100ms?

    - by James Holland
    I have 2 servers (Both: Windows Server 2008, Dual Xeon 2.8Ghz, 32GB RAM, 8 x 15k SAS Drives). One of them is a DC / Web server / Exchange Server, the other is a SQL Server (2008). I have a 48 port Netgear GS748T Gigabit switch. When I ping from server to server, I get ping times <1ms, great, but when I ping from a PC, I get varying pings from the occasional <1ms to 500ms!! If I log into either server and look at Task Manager, CPU usage peaks at 20%, memory usage is 100%, but I am led to believe this is normal as Exchange will just use as much as you have, and release it when requested. Network usage peaks at 1%. I really don't understand how the ping can vary that much. I know I am giving very little info, but this is all I know, I apologise, but can anyone help? In response to question, I have pinged by both IP address and hostname, no difference in ping times.

  • Apache server in raspberry PI not visible from outside( public IP)

    - by Kronos
    I have made a fresh install of Arch Linux ARM into a Raspberry PI and I mounted there a LAMP, all fresh. I have another Arch(x86) in my laptop with Apache also there, and as far as I know, two web servers cannot run in the same network segment so, the problem is as follows. I my laptop, having Apache running, if I enter via the public ip of my network everything turns ok and I can see my website but, (obviously turning this server down) if I enter from the public IP with the Apache running in the raspberry pi( yes, only that Apache running) i cannot see my website in there. Also, if I access via local network it is a normal success, I can see my website. So, I can enter my raspberry website only via local but in my other web server i can enter it via local and public. I have the same conf files in both of them so what is the difference? I was planning in making the rpi as a development server. Thanks in advance

  • Video acceleration problem with Windows 7 games and PPTX files

    - by Jordan 1GT
    I have a Dell xps M1330 which originally ran Vista, but I upgraded to Windows 7. When I try to run a Win 7 game like spider solitaire I receive the following message: The game is running in software rendering mode. Hardware acceleration is either disabled or not supported by your video card driver which could slow down game performance. Make sure you have the latest video card driver installed and that hardware acceleration is turned on. I confirmed that hardware acceleration is turned on. When I go to Dell's site, I'm told there is no later video driver. When I run the game it runs very choppy. I have a .pptx file which is doing strange things in normal view and I suspect it may be related to the same video acceleration problem.

  • OS specific network delay, why?

    - by Atilla Filiz
    Since my new ISP installed their own router to my house(I rented a room in a student house so don't have much control on these), I started having strange delays. Any outgoing connection I do, be it http or ssh, is delayed for several seconds, and once it is established, I have no further problems. I open several simultaneous tabs in my browser and after about 5 to 8 seconds, they all connect and load simultaneously and quiet fast. I can actually play online games once I connect.What's more interesting is, I experience this only with Linux distros, namely Arch and some versions of Ubuntu. Access with Windows installs are quiet normal. What might be wrong with my router? Everything was fine with my old router but I have to use this one now.

  • Why does my Mac always crash when I enable `ask for password after screensaver ended`?

  • Script to kill process at logoff doesn't execute until process is dead?

    - by robertc
    We have a program that, due to memory leaks in some of the screens, doesn't exit cleanly when the user quits. The problem is that this blocks the normal logoff procedure - you select logout and a few processes disappear but the user doesn't actually log off. Since I'm unable to fix the program, I thought I'd use a script run at logoff to kill the process. I've verified the script kills the process if I run it by double clicking and have added the script to Windows Settings - Scripts - Logoff on my machine in gpedit. Unfortunately it seems that the logoff scripts don't get run until all the processes have died, so it never runs. Is there a way to make the logoff scripts run at an earlier point in the process? Or is there a better approach to the issue?

  • Case for Micro SD card?

    - by Josh
    I have a MicroSD card which I'd like to keep with me at all times, I.E. in my wallet. I'm looking for a case for it. But all the cases I can find seem to be for standard SD cards... the closest I could find was this: Which is completly pointless, it stores the Micro SD card along with it's adaptor. Why not just put the Micro SD card IN the adaptor and store both on a normal SD card case... Anyway, does what I'm looking for (a case to protect a microSD card, and only large enough for a mircoSD card, i.e. not what's pictured above) exist?

  • File downloaded from IIS6/Win2003 server to a Mac (and not PCs) is incredibly slow

    - by Simon Swords
    We have a test zip file on our customers server that we host for him that when downloading to a Mac is incredibly slow. On a Mac - trying the download via Safari 5.0.3 and Chrome 8.0.552.231 results in a quick burst of normal download speed then plummets to almost no speed at all after 1 or 2 meg (between 1 and 5 Kb/s - yes, KiloBITS per second! According to the network monitor). Downloading via Windows was fine and speedy. Tested via; IE7 7.0.5730.13 and Chrome Portable 8.0.552.224 On Windows XP Pro, and; IE8 8.0.7600.16385 in a Windows 7 virtual machine running via VirtualBox 4.0.0 r69151 on the same Mac mention above Google hasn't helped us out on this occasion, possibly because the search terms I'm having to use are quite generic. Has anybody ever experienced this and if so how do we fix it? Thanks in advance

  • How to troubleshoot down terminal service/CITRIX sessions, when the process just won't terminate?

    - by Chad
    Running a CITRIX presentation server farm, version 4.5.6 on Windows 2003 sp2. In the CITRIX Access Management Console, I sometimes get a session that shows it's in a down state - but has none of the normal info associated with it (user name, applications, client name, idle time, etc...). It does say which servers it's on, so I check out that server's terminal services manager. I can see the down session but cannot reset it. I get: (Error 7024 - the requested operation cannot be completed because the terminal connection is currently busy processing a connect, disconnect, reset, or delete operation.) So I go to the task manager and look up the processes running under that session id. I see it's one of my published apps, but when I try to end the process - it simply does nothing and the process remains. Any way to get rid of these sessions without a server reboot?

  • bash process uses 90% CPU, comes back on computer restart

    - by Sano
    I’ve replaced the old HDD of my late 2008 unibody MacBook (8 GB of RAM, running OS X 10.7.4) with an OCZ Vertex 3 SSD. After doing this, I've installed Lion and restored my data from a Time Machine backup. Everything is fine, except for a process named “bash” that permanently uses about 90 % CPU. If I kill it via Activity Monitor, everything goes back to normal, but unfortunately the process comes back every time I restart the computer. I've tried do zap the PRAM, reinstall 10.7.4 from the combo package, and even simply wait for more than 2 hours, but the problem is still here.

  • Different settings for secure & non-secure versions of Django site using WSGI

    - by Jordan Reiter
    I have a Django website where some of the URLs need to be served over HTTPS and some over a normal connection. It's running on Apache and using WSGI. Here's the config: <VirtualHost example.org:80> ServerName example.org DocumentRoot /var/www/html/mysite WSGIDaemonProcess mysite WSGIProcessGroup mysite WSGIScriptAlias / /path/to/mysite/conferencemanager.wsgi </VirtualHost> <VirtualHost *:443> ServerName example.org DocumentRoot /var/www/html/mysite WSGIProcessGroup mysite SSLEngine on SSLCertificateFile /etc/httpd/certs/aace.org.crt SSLCertificateKeyFile /etc/httpd/certs/aace.org.key SSLCertificateChainFile /etc/httpd/certs/gd_bundle.crt WSGIScriptAlias / /path/to/mysite/conferencemanager_secure.wsgi </VirtualHost> When I restart the server, the first site that gets called -- https or http -- appears to select which WSGI script alias gets used. I just need a few settings to be different for the secure server, which is why I'm using a different WSGI script. Alternatively, it there's a way to change settings in the settings.py file based on whether the connection is secure or not, that would also work. Thanks

  • ICMP Data Field Modified - What does it Mean?

    - by Lucretius
    Normal ICMP Data fields are composed of a pretty standard 32 byte string of alphabet characters. abcdefghijklmnopqrstuvwabcdefghi I have captured a series of ICMP echo requests using WireShark with a modified Data field and I have no idea what it means. (Underscores represent spaces.) abcdefghijklmnopprstuvwxyzabcdefghi abcdefghijklmnoparstuvwxyzabcdefghi __abcdefghijklmnopsrstuvwxyzabcdefghi __abcdefghijklmnopsrstuvwxyzabcdefghi __abcdefghijklmnopwrstuvwxyzabcdefghi __abcdefghijklmnopdrstuvwxyzabcdefghi__ Note: The position of the "q" character The addition of "xyz" The addition of spaces before and after the payload When you look at the position of "q" horizontally it spells "passwd" which is a Linux/Unix command for changing a users password. Any ideas?

  • How to lock Firefox tab to domain or URL pattern

    - by f3lix
    I know Firefox extensions that allow protecting (cannot be closed) and locking (cannot change URL) tabs. What I need is an extension that locks a tab to a certain domain or URL pattern. For example, I want to lock a tab to the domain example.com. As long as I follow links that are within this domain the tab should show normal (unlocked) behavior, but if I follow a link to another domain the link should be opened in new tab -- leaving the locked tab open with a URL within the locked domain. Even better would be the functionality to lock a tab to a URL pattern. If a URL matches the pattern it is opened in the current tab, otherwise it is opened in a new tab. Do you know something (preferably an extension for FF 8.0) that provides this kind of functionality.

  • .NET Framework 4.0 installation is very slow

    - by Dimitri C.
    On my Windows Vista, it takes a full 12 minutes to install the .NET Framework 4.0. a) Is this normal? b) If not, can something be done about it? The reason I'm concerned about the speed is because it slows down the testing of our product installer considerably. Testing an installer is time consuming already, but this new .NET Framework installer makes it almost undoable. Detail: I did the test on a clean Vista inside a VirtualBox virtual machine. This setup does not show any performance issues in other situations. I tried both dotNetFx40_Full_x86_x64.exe and dotNetFx40_Client_x86_x64.exe. They both take approximately the same time to install.

  • dns update frequency

    - by Roderik
    I was looking after the frequency of dns updates, since I had to change the location fo the vps that hosts the domain contents. What I ussualy read is that it takes up to 72 hours to get these changes propagated, sometimes this can be sooner based on your location. I changed the nameservers for the domain vasco-da-gama.nl about a week ago. When I ping the domain name from different locations it still points the old vps (which does not exist anymore). I was wondering if its normal that it can take this long for the change to point my new vps? If I might have done something wrong here, where should I look for it (it looks all ok, when I check it). If it is reachable from your location (if so, its probably a matter of time it will propagate to my location).
