• Almost 2013 - Any decent options for mp3 to text? (Speech Recognition)

  - by ajacian81

  I know there's some questions here on s/u regarding converting spoken word mp3 to text, however, most are pretty old (2010 and earlier). I'm just wondering if there's any new legitimate options for this task - if google has shown us anything, speech recognition has come a long way. Personally, I'd prefer a linux based solution, but I'm not picky. I've heard a lot about something called Sphinx, but I tried to set it up and get it going but I couldn't. I know there's a number of different componenents for Sphinx so maybe I was doing it wrong? Either way, are there any new applications for Speech recognition, especially from MP3 files? Thanks!

• Are there any statistics on the number of networks using Ethernet Jumbo frames?

  - by Russell Heilling

  I am often told by Sales Engineers and Product managers that a Layer 2 Ethernet service is not fit for purpose if the maximum supported frame size is in the 1518-1522 range (enough to support standard Ethernet frames or VLAN tagged frames). Or in other words: an MTU of 1500 is not enough (see this blog post for my definition of MTU and a short rant on how the term is often misused) I am never able to get any details from them on: a) What proportion of customers (Enterprise / SMB) require Jumbo frames b) What are typical expectations on frame size for Jumbos on WAN links? 1600, 2000, 9k, etc... I know that in Telco and Data Centre environments Jumbos are pretty common, but I am after some insight as to how common this is within Enterprise and SMB networks.

• How can I view my IIS hosted sites on other machines on my network

  - by Truegilly

  Hello, at home i have a simple network setup conatining 2 machines and 1 belkin router. On one machine i have a site hosted with IIS7. Rather than the standard localhost/index.htm address i have added an entry in the HOSTS file pointing the local ip (127.0.0.1) to this domain - www.mysite.dev. i can access the site with www.mysite.dev with no problem. what i would like to do is be able to view this site from my other machine on the network. initially i assumed this could be done with a url like so MACHINE-NAME/www.mysite.dev, but the connection always times out. But I can ping MACHINE-NAME without problems. For testing purposes i have diabled the windows firewall on both machines but to no joy. Like a typical web developer, my techy/network skills are pretty poor. Can anyone see where im going wrong ?? thank you for your time Truegilly :)

• Flushing disk cache for performance benchmarks?

  - by Ido Hadanny

  I'm doing some performance benchmark on some heavy SQL script running on postgres 8.4 on a ubuntu box (natty). I'm experiencing some pretty un-stable performance, even though I'm supposed to be the only one running on the machine (the same script on the exact same data might run in 20m and then 40m for no specific reason). So, remembering my distant DBA training, I decided I should flush the postgres cache, using sudo /etc/init.d/postgresql restart, but it's still shaky! My question: maybe I'm missing some caches in my disk/os? I'm using a netapp appliance as my storage. Am I on the right track? Do I even want to make sure I get repeatable performance before I start tuning?

• Installing Windows 8 over Windows 7 with Ubuntu installed using wubi (both on `C:\`)

  - by peat-ar

  Current state I'm using both - Ubuntu (installed via Wubi on the same drive as Windows) and Windows 7 - quite frequently. I just bought the upgrade to Windows 8 and was curious to try it out, however I'm quite insecure whether Windows 8's "secure boot" will exclude my current Ubuntu installation and if it's even possible to keep it. So... is there any way to upgrade to Windows 8 without overwriting Ubuntu? (I really don't want to reinstall it, as a lot of customization has been done here and taking backups and all would get pretty wearing (same case for Windows 7 - if possible, I'd like to keep my files)) This is not a dublicate of Installing Windows 8 over Windows 7 with Ubuntu installed using wubi? because this question only deals with the case when Ubuntu has been installed on (e.g.) D:\ (while Windows is being installed on C:\)

• Specify Credentials to run Powershell Script to Query AD

  - by Ben

  I want to run a powershell script to query AD from a machine that is NOT on the domain. Basically I want to query to see if there is computer account already on the domain for this machine and create it if there is not. Because this has to happen before the machine joins the domain I assume I will need to specify some credentials to enable it to run. (I'm pretty new to Powershell, so apologies if this is a newbie question!) The script I am using to check the account is below, and then once this has run it will join the domain using the computername specified. Can you tell me how to specify some domain credentials to run this section of the script as? Cheers, Ben $found=$false $thisComputer = <SERVICE TAG FROM BIOS> $ou = [ADSI]"LDAP://OU=My Computer OU,DC=myDomain,DC=com" foreach ($child in $ou.psbase.Children ) { if ($child.ObjectCategory -like '*computer*') { If ($child.Name -eq $thisComputer) { $found=$true } } } If ($found) { <DELETE THE EXISTING ACCOUNT> }

• How do I enable write access for an sFTP only user under Ubuntu?

  - by Jon Cage

  I'm running Ubuntu 12.04 and am trying to configure a user to allow chroot'd sFTP connections to another section of the filesystem. I've added the following to my /etc/ssh/sshd_config file: Match Group mygroup X11Forwarding no AllowTcpForwarding no ForceCommand internal-sftp ChrootDirectory /home/%u I've set their home directory so that it's owned by root but has their group. I've created a mount --bind from /home/myuser/transfers to /my/filesystem which appears to be navigable. The problem I'm having is that I'm not able to write to any part of the filesystem which makes this pretty useless as an FTP server. What am I missing? What can I check?

• How many cron jobs are too many?

  - by guitar-

  I have a couple of cron jobs for basic maintenance which aren't very resource-intensive. I also have custom task scheduling (which is just calling a .php file and passing information via GET, ie: cronjob.php?param1=param ...). These can add up pretty quickly. These just call system commands and run external programs (Nmap is one of them). They usually don't take long either. Anyway, can anyone tell me, roughly what point is too many? I know it's hard to say since it depends on what job is being run and how often, but at what point does the crontab program start "struggling"? Anyone have any idea? Thanks.

• Manage song metadata on CentOS from command line

  - by Puddingfox

  I am making a simple Pandora.com alternative for myself and a few friends where the user can upload his/her songs and listen to them anywhere. My intent is to make a lightweight, simple player in HTML5 so all the user needs is a current Firefox or Chrome to use it. I have set it up so that all uploaded songs get converted to .ogg and added to a database but I also want some metadata (not sure if that is the correct term) for the songs to be stored in the database so the player can tell the user what song he/she is listening too. I know there are several GUI tools for managing the title/artist/album info for songs but I'm having trouble finding any good ones I can use from the command line. If the song has the information already in the file, I think I can use mplayer to retrieve the information but it would be really great if there was one that would look up the song information online. I don't mind interfacing with an API (would be pretty interesting actually). Do you guys have any suggestions?

• Best way to duplicate databases nightly?

  - by Margaret

  Hey all We just got two new servers, that are running Windows Server 2008. The intent is to make the machines pretty much identical, copying the content of the master to the slave on a nightly basis, so that if anything fails, the second copy can stand in immediately. It doesn't need to be up-to-the-minute mirroring, though I suppose that wouldn't hurt if performance is not affected. The two machines will, amongst other things, each be running an instance of SQL Server 2008. The aim is to duplicate the databases on the master down to the slave on a nightly basis. Unless I'm misunderstanding, the slave databases in mirrored databases require the primary to be present to work correctly; I'm hoping for some solution where we have a second machine that can be up and running with minimal downtime if the first one falls over. Am I misunderstanding mirroring? Is that the best way to do things, or should I use some other mechanism? If so, what?

• 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?

• Should my servers boot from VHD?

  - by tony roth

  I've been testing native vhd boot on several servers. It seems to be pretty transparent in terms of deployment and with my seat of the pants testing I have not noticed any difference in performance. The main reason that I want to boot vhd is due to their transportablility between different hardware and to hyper-v servers. the following roles will be installed. dfsr dhcp iis application server dc <- haven't tested this yet but see no reason why it won't work. With the above low impact (in terms of performance) roles do you thing booting from VHD is appropriate. thx

• Pros/cons to turning off cable modem

  - by Jay

  A little off the wall perhaps, but ... I have a cable modem and a router for a wireless home network. Is it a good or a bad idea to turn it off at night and during the day when we're all at work or school? Or should I leave it on 24/7. I was thinking that leaving it on constantly makes me more vulnerable to hackers, not to mention wasting electricity. (Though I'd guess the amount of electricity used by a cable modem and a router is probably pretty trivial. Still, every little bit helps.) When I have turned it off and turned it on again, it takes several minutes for it to go through its little dialog with the cable company and get me connected to the Internet again, which is annoying but not a big deal. Anyone know any good reasons one way or the other?

• Apache2 BufferedLogs On - anybody using it ?

  - by Qiqi

  Greetings, I am wondering, whether anybody is using BufferedLogs On with Apache2 and found any issues ? Feature is marked as experimental, but for many years now, so I guess it's rather pretty stable. I am running some servers with constrained disk IO capacity at the moment, so I turned it on hoping that even a small benefit could help in the long run ;-) I do have several to several hundreds requests per seconds so by my thoughts there is really no need to write to log after each request, cause honestly I don't think that my filesystem is the best handler for many unnecessary writes. (OCFS2 shared among several DomUs in the Xen)

• Keyboard lights sometimes stay on after PC is powered off. Why?

  - by Vilx-

  Sometimes when I power off my PC some lights on the keyboard stay on. It's pretty random which ones, though I suspect it has something to do with what lights were on just before the shutdown (if I vigorously follow that they are all off while the PC is shutting down then they stay off). Not that this would change anything, but it is annoying. Why does this happen and how can I avoid it? Added: I know that I can turn off the power completely to my computer and it will go off. That's not the point. Actually, I even want my keyboard to have power, because I use it to turn on my computer (the power button on the case is difficult to reach). I just want the lights to go off. Or at least understand why this happens. Oh, and it's a PS2 keyboard.

• How to either completely remove SQL Server 2008 R2 Installation or repair it?

  - by Nico

  I've installed MSSQL server correctly, then I took some wrong turns and I'm now left in a pretty undesirable state. I wanted to change the server instance to another drive, so I uninstalled SQL server and all of it's features from the Programs and Features control panel. Now when I tried to install a new instance, I got a few errors, but it still installed most of them: Then I tried to run a repair, which I figured would fix things, but it throws an exception about not being able to read something from the CD (tried more than once always the same exception) Error 1316.A network error occurred while attempting to read from the file R:\1033_ENU_LP\x64\setup\SSCERuntime_x86-enu.msi , and it fails to repair a few of the features: And I don't have the server instance installed either. So I'm left with no MSSQLMS, no server instance, and no happiness. What would be the best course of action here?

• How to get Mac OS X Terminal.app and screen/vim scrolling to play nice?

  - by rustychains

  OSX 10.6.3 Terminal.app Am a pretty dedicated screen user. Terminal.app line buffer and/or scroll does not seem to work for me. That is while in screen anything that goes past the top of the frame is gone, can't scroll back to. This seems to work ok in other terminal apps gnome, cygwin. Perhaps this is a shell env, config, or command? .screenrc: startup_message off autodetach on shell -$SHELL vbell off defutf8 on caption always caption string "%{= wk}%w" I have tried using defscrollback here with different values, but doesn't have an effect. some .bashrc settings: set -o physical export TERM=xterm-color shopt -s checkwinsize

• Online Backup strategy for family individuals

  - by marlon brando

  The majority of my family, including myself, uses Dropbox and Syncplicity free accounts for our syncing needs. However our backup strategy is pretty non-existent, we all have access (via webDav) to our qnap nas located at home, however we copy files accross when we can remember to do so, terrible I know. Is there tools like CrashPlan or Spideroak that allows each the accomodation of each family members syncing and back-up needs under one main account? I'm not sure how this would work, as each family member would need a seperate sub-account or would I manage each computer's syncing and backup lists from a single account? Any thoughts?

• Does Dynamic DNS require separate subdomains?

  - by kce

  Hello. I have a functioning DHCP/DNS (ISC Bind 9.6, DHCP 3.1.1) server running on Debian that I would like to add DynamicDNS functionality to. I have a pretty simple question: Does DynamicDNS require (or recommend) separate sub-domains? I have seen a few tutorials where the the clients that are acquiring their IP addresses and other networking information via DHCP are on a different sub-domain as the servers which are statically configured (both in terms of IP, and DNS). For example: All the clients are on ws.example.org and the servers on example.org. Right now all of our servers and clients are in the same domain (example.org) but spread across different zone files (because we have multiple subnets). The clients are configured with DHCP and the servers are configured statically. If I want to setup DynamicDNS for the clients should I use a separate sub-domain? What's the best practice here (and why or why not would it be a bad idea to do otherwise)? Thanks.

• How safe is locking the screen?

  - by D Connors

  So, both windows and linux have a pretty useful feature that allows you to leave everything running on the PC while also keeping invaders away by locking the screen. My question is: Say I leave my laptop with the screen locked while I go get a donnut, and then it gets stolen. Assuming the thief has access to whatever software he needs, how easy/hard would it be for him to access my (currently logged-in) account? Now let me be clear. I'm not asking if he can access the data on the harddrive. I know he can, and that issue would go under data encryption, which is not my question here. I'm focusing on how hard would it be to get around the "Insert Password" screen, and have full access to my account. I'm looking for answers regarding both OS's; but, if needed, assume Ubuntu. Thank you.

• Apache 2.0.55/PHP 5.3.5 Hangs

  - by Rushyo

  Recently inherited a Windows 2k3 server running XAMPP, including ancient copies of PHP, MySQL and Apache. I'm attempting to install a second, up-to-date PHP installation on the machine so I can reference that in future instead of XAMPP's old one. Apache starts up with this new PHP installation happily. Unfortunately, when Apache references the new PHP install, whenever I try a view a page (even a non-PHP page) it hangs. The server simply doesn't respond to any HTTP request - it doesn't crash either. It just sits there with the connection open. There are no errors/warnings/notices in either the PHP or Apache logs. I've pretty much ruled out PHP's extensions (by process of systematic elimination) and most of the INI settings. I've tried reinstalling PHP from scratch. The PHP installation is PHP 5.3.5 x86 thread-safe compiled w/ VC6. The Apache installation is Apache 2.0.55. Anyone encountered similar behaviour?

• Data Recovery needed with a Sector Zero problem on a HDD

  - by Jay Robins

  Left my computer (running XP) copying files to an external drive. Came back a few hours later, and the laptop was pretty hot and had frozen (Ironic aint it). Forced a reboot, and the laptop HDD hasnt worked since. Set it up in an external enclosure, but XP cant mount the HDD to a drive letter, but is able to recognize the manufacturer and drive size (Hitachi-320GB). No noise or rattling when the drive is spinning, but I cant get anything off of it, since i cant mount it, or see much of anything. Computer repair shop ran some software tests and says it came back with a "Zero Sector bad" message, and need to send it to a professional data recovery service. Any other options or ideas, before I have to spend thousands of dollars to recover my data? Any help would be GREATLY appreciated!!! I'm desperate and a poor student! Thanks in Advance, -Jay

• Can a company use VPN to spy on me?

  - by orokusaki

  I'm about to work with a company on a development project, but they first need to set up a pretty complicated environment, and suggested they use VPN to work on my machine to do this. Should I be concerned that somebody can just watch me work? It would be embarrassing, if somebody could witness my work habits (e.g. Asking questions on SO and researching all day is part of my daily work regiment, and makes me feel like a noob, but it keeps me sharp. I also listen to conspiracy videos all day, and RadioLab podcasts, :). Is VPN going to introduce this possibility, and if so, is there a way around it? EDIT: Also, is there a way I can always tell when somebody is VPNed into my computer?

• In windows 7, how do I disable "Ease of Access" pop ups on the logon screen as I am typing my passwo

  - by Silfheed

  Heyas So the question is pretty much in the title. Things to note: 'Use On-Screen Keyboard' is un-checked I have disabled Ease of Access by replacing utilman.exe But my problem now is that when I'm typing my password, It'll stop all together on the 'u' or the 'p' character and I have to click on the ease of access button then move focus back to the password to continue. Yes, one obvious solution is to not use a password that has 'u' or 'p' in it (which I've done), but that's obviously not a completely satisfying answer. Thanks! I feel a tumbleweed badge...
