  • Why is preserving the pitch in audio playback (allegedly) less performant?

    - by Markus Unterwaditzer
    In VLC for Android, i discovered an option to preserve the pitch during faster-than-normal playback: The "requires a fast device" obviously implies that faster playback is more performant when the pitch is changed too. Why is that so? What i've tried: Before posting this question i did some shallow research through Google. According to Wikipedia, there are several methods for faster playback of audio, the "simplest" one (Resampling) changes the pitch.

  • My VPS ubuntu server is very slow

    - by askmike
    I just installed a frech copy of Ubuntu 12.04 on my vps because my old installation was very slow, unfortunately this did not fix the problem. With slow I mean requests for my PHP websites take a long time, very slow (30 sec per request) to slow (3+ sec per request). When it's really bad SSH is also laggish. The websites are: askmike.org (pretty standard Wordpress) mvr.me (own PHP) slow? very slow: Here is a picture of loading a clean install of wordpress slow: here is a picture of loading a small PHP based website the vps The VPS has 256mb ram and an 25GB hdd. Besides serving the 2 small websites it isn't doing anything AFAIK. What have I installed Clean Ubuntu server 12.04 LAMP stack few things like git and nodejs (not using both) ossec (because I thought my server was getting hammered) munin What I already tried / done I installed munin so that I could watch io speed and such. The problem is that I don't know where to look for in the munin report. I checked logs and don't see anything strange (although I don't really know where to look for besides strange / repetitive errors and GET requests). I configured Apache MPM to: <IfModule mpm_prefork_module> StartServers 5 MinSpareServers 5 MaxSpareServers 10 MaxClients 40 MaxRequestsPerChild 0 </IfModule> (apache is using prefork, the default) Stats I copied the munin report as it appeared at 4:50 last night to a site hosted on a shared webhost. Note that tonight my mysql crashed somewhere after 1:00 (which is a new problem altogether), so therefor the graph for last night might look strange. Can anyone help me get my VPS up to normal speed? EDIT: Thanks for the replies. The VPS is 10 bucks a month and is from directvps.nl (Dutch host and I'm also dutch). I did two speed tests for disk IO: $ dd if=/dev/zero of=test bs=64k count=16k conv=fdatasync 1073741824 bytes (1.1 GB) copied, 23.1506 s, 46.4 MB/s $ dd if=/dev/zero of=test bs=64k count=16k conv=fdatasync 1073741824 bytes (1.1 GB) copied, 39.3796 s, 27.3 MB/s Anyway: how can I prove to my VPS host that it is to slow? I can understand a server being busy slowing a website down. But 5-30 sec loadtime for a normal PHP webpage?

    I am unable to run psql with my normal Mac user account in Terminal session, although I can do it using the postgres service account). When I enter the command psql mydb and type my password, I get the following message: WARNING: password file "/Users/beh/.pgpass" has group or world access; permissions should be u=rw (0600) or less But I cannot find .pgpass. How do I set up and add users to my PostgreSQL 9.1 database on Mac OS X 10.6.8?

  • Replacement for public folder workflow, I'm confused as to how sharepoint does it.

    - by RodH257
    For years Microsoft has been slowly phasing out public folders, perhaps exchange 2010 really is the LAST TIME they'll be shipped... I've heard sharepoint is the replacement, but I don't understand full, can someone give me an idea of how to replace this workflow? In our office, we have projects, they have a project number, ie 10353. Each job folder has a public folder, organized in a hierachy like Projects Year Folder Subfolders The main subfolder we use is for genera correspondence. When an email is received that relates to a project, it is dragged and dropped (or right click move to) a public folder. Adding public folder favourites for each user helps this. When an email is sent, we have a custom email form, which is the default email form, but with a project number field next to the subject line. When you enter the job number in there, it carbon copies our filing system in, which reads the job number and puts the email in the public folder for you. if you need to refer to emails, you go to public folder and find them there. This isn't the best with large jobs, but it works ok. Now, I have limited experience with sharepoint (well, WSS), we've used it to do some neat discussion boards/polls etc as an intranet site, but I haven't seen much of its integration with outlook. The great thing about our solution is how tightly it integrates with outlook which is exactly where the emails are. If you want to forward an old email, you go to public folder and forward it, simple. Any solution that replaces it should be at least as easy as this. Improvements we would like would be to have better searching of emails, better support in exchange (ie future version) and also, custom forms in outlook are being phased out (the VBA kind), so avoiding these would be good. Does sharepoint do this? or what solutions do this kind of thing?

  • Running .NET code in XML file [closed]

    - by Stuart McIntosh
    We have 2 servers, 1 already configured with .net which works fine and a new one which appears to be configured the same but when I open an xml page in Internet Explorer it complains about the <% tag. We have IIS on win srvr 2003 SP2. The website is configured with .NET 1.1.4322. In ISAPI extensions have set the .XML extension to use c:\windows\microsoft.net\framework\v1.1.4322\aspnet_isapi.dll But the page: <property name="documentmaxage" value="0"/> <property name="documentmaxstale" value="0"/> <var name="m_Prompt_Path" /> <form id="InitVoiceXmlDoc"> <block> <assign name="m_Prompt_Path" expr="&quot;<% Response.Write(Request.QueryString["m_Prompt_Path"]); %>&quot;"/> </block> </form> gives the error: The XML page cannot be displayed Cannot view XML input using XSL style sheet.

  • Revert Skype contact list to be like it was before the latest update

    - by mickburkejnr
    My Skype client has been updated to the latest version (on Windows 7). In the new version it's grouped all my Facebook contacts in along with my normal Skype contacts. I've tried to get used to it but it's being an absolute pain when you start a conversation with a contact, only to find your speaking to them through their Facebook account and not their Skype. Is there any way I can revert my Skype client to split the Skype contacts from the Facebook contacts like it was before this update?

  • Apache not finding index.php by default, set rule for routing through index.php

    - by eoinoc
    Apache on the server is set to find index.php by default, and that works for a normal folder. However, I have a .htaccess rule to route all requests through my routing script: RewriteEngine On RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^(.*)$ index.php [QSA,L] With these .htaccess contents, the server returns a 404 error. Only by specifying /index.php does the routing script get called. Any tips on what I am doing wrong?

  • Ways to make USB Firefox faster

    - by MichaelKay
    I have several laptops so I use a USB key version of Firefox to keep my environment as I move around. I followed the suggestions offered on the Firefox web site (turn off the cache and history etc.) and its better but still much slower than the normal version. Other than buying a new, super fast flux-capacitor based USB key, what other tips and tricks can I use?

  • MongoDB and datasets that don't fit in RAM no matter how hard you shove

    - by sysadmin1138
    This is very system dependent, but chances are near certain we'll scale past some arbitrary cliff and get into Real Trouble. I'm curious what kind of rules-of-thumb exist for a good RAM to Disk-space ratio. We're planning our next round of systems, and need to make some choices regarding RAM, SSDs, and how much of each the new nodes will get. But now for some performance details! During normal workflow of a single project-run, MongoDB is hit with a very high percentage of writes (70-80%). Once the second stage of the processing pipeline hits, it's extremely high read as it needs to deduplicate records identified in the first half of processing. This is the workflow for which "keep your working set in RAM" is made for, and we're designing around that assumption. The entire dataset is continually hit with random queries from end-user derived sources; though the frequency is irregular, the size is usually pretty small (groups of 10 documents). Since this is user-facing, the replies need to be under the "bored-now" threshold of 3 seconds. This access pattern is much less likely to be in cache, so will be very likely to incur disk hits. A secondary processing workflow is high read of previous processing runs that may be days, weeks, or even months old, and is run infrequently but still needs to be zippy. Up to 100% of the documents in the previous processing run will be accessed. No amount of cache-warming can help with this, I suspect. Finished document sizes vary widely, but the median size is about 8K. The high-read portion of the normal project processing strongly suggests the use of Replicas to help distribute the Read traffic. I have read elsewhere that a 1:10 RAM-GB to HD-GB is a good rule-of-thumb for slow disks, As we are seriously considering using much faster SSDs, I'd like to know if there is a similar rule of thumb for fast disks. I know we're using Mongo in a way where cache-everything really isn't going to fly, which is why I'm looking at ways to engineer a system that can survive such usage. The entire dataset will likely be most of a TB within half a year and keep growing.

  • How does data I/O takes place on USB Flash Memory ?

    - by user35704
    I want to know how is data I/O takes place on flash drives which are typically EEPROM's . I thought so as I was writing a C Program that involves file handling . For a normal HDD , that would involve returning the file pointer and reading or writing data to the disk which would be done by read/write HEAD . While in EEPROM's there is no read/write head , as it's works on mnemonic commands , So how come does the C file handling program works when I apply it to a file on flash drive ?

  • Is it possible/advisable to run VMware Server ESX/ESXi on a laptop?

    - by cletus
    The idea of having a small footprint hypervisor as the primary OS on a laptop or desktop where every "real" OS is a guest appeals to me. Now I realize this software is more typically used on blades and the other servers but can it be done on a normal PC? Should it be? What requirements are there (eg hardware/BIOS/chipset)? Is there a performance impact for doing so? Is it a good/bad idea?

  • 2 routers at home- how to connect with VNC?

    - by Charles Leviton
    I have two routers at home. First router is upstairs and is connected to the cable modem. 2nd router is downstairs and acts as "signal booster" for the 1st router. Devices connected to the upstairs router have IP addresses of the form 192.168.1.n Devices connected to the upstairs router have IP addresses of the form 192.168.2.n. I blindly followed instructions from a website to do this set up, just glad it works! Upstairs I have a PC running Win 7 64 bit. Its assigned IP is 192.168.1.7. I have a VNC viewer running on this. Downstairs I have a 2nd PC running Vista 32 Home edition bit that is connected to the 2nd router and has IP Address 192.168.2.114. VNC server is running on this. It's listening on 5900. There is no firewall. When I try to connect to this downstairs PC from upstairs it fails with message "Failed to connect to server". I cannot ping to this either. If I try to connect to this downstairs PC using VNC Viewer from another computer that's connected to the same downstairs router then it works like a charm. So what's the work around if the viewer is on a different "network"? I don't have any problems doing remote desktop connection from the downstairs PC to the upstairs PC even if they are connected to different routers. Router information- Upstairs- ASUS RTN13U, downstairs- DD-WRT v24 RC-5 Thanks! P.S. I posted this on the Ultra VNC forum as well but that doesn't seem to have a lot of activity, so taking the liberty to multipost.

  • PC will POST whenever feels likes it

    - by kyrpas
    I'm really sick of my PC and I'd love to throw it off the 5th floor but unfortunately I don't have this luxury right now. The issues started when I moved to a new house about 2 months ago. I didn't have this problem before. Case: Arctic Cooling Silentium T1 with embedded Fusion 550 Eco 80 PSU. M/B: ASRock A790GMH/128M Gfx: ATI Radeon HD 5770 Here's what's happening almost on a daily basis: I wake up in the morning, switch on the PC and all the fans start spinning. 9/10 the graphics fan stays on 100% and I know it won't post. If I'm lucky, ATI's fan stays on full power for a second, then goes back to normal and I get a normal post but that doesn't happen often. No, instead it's just drives me crazy. When I get no POST I'm trying a lot of different things and what bothers me the most is that they all work. But not always. No... That way I could find out what the hell is going on and we don't want that.. right? So, sometimes it manages to POST if I: remove the keyboard remove the power cable for a few minutes remove the graphics card remove the HDD cables do nothing, just turn it on and off a few times Sometimes it doesn't POST even if I do all of the above. And I end up removing all power cables from the M/B, and connecting all the stuff one by one. Sometimes it works, sometimes it doesn't and I just have to pray and wait. What the hell is that? I'm getting pissed of again just thinking about it. The only solution is to leave it on 24/7 but I don't want to do that. It should be able to turn on and off when I press the power button. I'm not asking much. I'm starting to think there's some weird electricity/power issue but I really don't understand what it is. There's no logical explanation about it. At least I can't find one. Any ideas?

  • Using Sigmatel STAC 92XX on Windows 7 RTM x64, cannot get 5.1 surround sound to work

  • Removing file with strange characters in filename in OS X

    After a memory error in my program, I am stuck with a file with a strange filename. It's proving quite resistant to all normal methods to remove files with strange names. The filename is: %8BUȅ҉%95d%F8%FF%FF\x0f%8E%8F%FD%FF%FF%8B%B5T%F8%FF%FF%8B%85\%F8%FF%FF\x03%85x%F8%FF%FF%8B%95D%F8%FF%FF%8B%BD%9C%F8%FF%FF%8D\x04%86%8B%B5@%F8%FF%FF%89%85%90%F8%FF%FF%8B%85X%F8%FF%FF\x03%85%9C%F8%FF%FF%C1%E7\x02%8B%8Dx I tried the following: rm * - "No such file or directory" rm -- filename - "No such file or directory" rm "filename" - "No such file or directory" ls -i to get the inode number - "No such file or directory" stat filename - "No such file or directory" zip the directory where the file is in - error occured while adding "" to the archive. delete directory in finder - error -43 in python: os.unlink(os.listdir(u'.')[0]) - OSError No such file or directory find . -type f -exec rm {} \; - "No such file or directory" checked for locks on the file with lsof - no locks All these attempts result in a file (long filename here) not found error, or error -43. Even the ls -i. I couldn't find anymore options, so before reformatting or repairing my filesystem (fsck might help) I thought maybe there is something I missed. I wrote this small c program to get the inode: #include <stdio.h> #include <stddef.h> #include <sys/types.h> int main(void) { DIR *dp; struct dirent *ep; dp = opendir ("./"); if (dp != NULL) { while (ep = readdir (dp)) { printf("d_ino=%ld, ", (unsigned long) ep->d_ino); printf("d_name=%s.\n", ep->d_name); } (void) closedir (dp); } else perror ("Couldn't open the directory"); return 0; } That works. I now have the inode, but the normal find -inum inode -exec rm '{}' \; doesn't work. I think I have to use the clri now.

  • IIS6 Log time recording problems

    - by Hafthor
    On three separate occasions on two separate servers at nearly the same times, 6.9 hours seemingly went by without any data being written to the IIS logs, but, on closer inspection, it appears that it was all recorded all at once. Here's the facts as I know them: Windows Server 2003 R2 w/ IIS6 Logging using GMT, server local time GMT-7. Application was still operating and I have SQL data to prove that Time gaps appear in log file, not across two # headers appear at gap Load balancer pings every 30 seconds No caching Here's info on a particular case: an entry appears for 2009-09-21 18:09:27 then #headers the next entry is for 2009-09-22 01:21:54, and so are the next 1600 entries in this log file and 370 in the next log file. about half of the ~2000 entries on 2009-09-22 01:21:54 are load balancer pings (est. at 2/min for 6.9hrs = 828 pings) then entries are recorded as normal. I believe that these events may coincide with me deploying an ASP.NET application update into those machines. Here's some relevant content from the logs in question: ex090921.log line 3684 2009-09-21 17:54:40 GET /ping.aspx - 80 404 0 0 3733 122 0 2009-09-21 17:55:11 GET /ping.aspx - 80 404 0 0 3733 122 0 2009-09-21 17:55:42 GET /ping.aspx - 80 404 0 0 3733 122 0 2009-09-21 17:56:13 GET /ping.aspx - 80 404 0 0 3733 122 0 2009-09-21 17:56:45 GET /ping.aspx - 80 404 0 0 3733 122 0 #Software: Microsoft Internet Information Services 6.0 #Version: 1.0 #Date: 2009-09-21 18:04:37 #Fields: date time cs-method cs-uri-stem cs-uri-query s-port sc-status sc-substatus sc-win32-status sc-bytes cs-bytes time-taken 2009-09-22 01:04:06 GET /ping.aspx - 80 404 0 0 3733 122 3078 2009-09-22 01:04:06 GET /ping.aspx - 80 404 0 0 3733 122 109 2009-09-22 01:04:06 GET /ping.aspx - 80 200 0 0 278 122 3828 2009-09-22 01:04:06 GET /ping.aspx - 80 200 0 0 278 122 0 2009-09-22 01:04:06 GET /ping.aspx - 80 200 0 0 278 122 0 ... continues until line 5449 2009-09-22 01:04:06 GET /ping.aspx - 80 200 0 0 277 122 0 <eof> ex090922.log #Software: Microsoft Internet Information Services 6.0 #Version: 1.0 #Date: 2009-09-22 00:00:16 #Fields: date time cs-method cs-uri-stem cs-uri-query s-port sc-status sc-substatus sc-win32-status sc-bytes cs-bytes time-taken 2009-09-22 01:04:06 GET /ping.aspx - 80 200 0 0 277 122 0 2009-09-22 01:04:06 GET /ping.aspx - 80 200 0 0 277 122 0 ... continues until line 367 2009-09-22 01:04:06 GET /ping.aspx - 80 200 0 0 277 122 0 2009-09-22 01:04:30 GET /ping.aspx - 80 200 0 0 277 122 0 ... back to normal behavior Note the seemingly correct date/time written to the #header of the new log file. Also note that /ping.aspx returned 404 then switched to 200 just as the problem started. I rename the "I'm alive page" so the load balancer stops sending requests to the server while I'm working on it. What you see here is me renaming it back so the load balancer will use the server. So, this problem definitely coincides with me re-enabling the server. Any ideas?

  • Encrypt client connection with squid forward proxy using SSL

In other words, I want my connection from my web browser to my forward proxy to be encrypted even though I'm just surfing normal http website through that proxy. Can it be done?
