  • Is there an equivalent to Airfoil available for Linux?

    - by Chris Adams
    Hi there, I just stumbled across this Airfoil on Mac OS X, which lets me 'throw' music from my laptop to any other linux machine, iPhone or other device hooked up to a better set of speakers than my laptop - here's the page below: http://www.rogueamoeba.com/airfoil/mac/ What tools would I use to recreate this functionality on a linux box - are there any nice GUI interfaces to something like pulse audio (which is what I imagine I'd use ) for doing this? Thanks

  • Trying to grok Linux quotas, where is the data stored?

    - by CarpeNoctem
    So all the tutorials and documentation for the Linux quota system has left me confused. For each filesystem with quotas enabled/on where is the actual quota information stored? Is it filesystem metadata or is it in a file? Say user foo creates a new file on /home. How does the kernel determine whether user foo is below their hard limit? Does the kernel have to tally up quota information on that filesystem each time or is it in the superblock or somewhere else? As far as I understand, the kernel consults the aquota.user file for the actual rules, but where is the current quota usage data stored? Can this be viewed with any tools outside repquota and the like? TIA!! Update: Thanks for the help. I had already read that mini-HOWTO. I am pretty clear on the usage of the user space tools. What I was unclear on is whether the usage data was ALSO in the file that stored per-user limits and you answered this with a yes. From what I can tell, rc.sysinit runs quotacheck and quotaon on startup. The quotacheck program analyzes the filesystem, updates the aquota.* files. It then makes use of quota.h and the quotactl() syscall to inform the kernel of quota info. From this point forward the kernel hashes that information and increments/decrements quota stats as changes occur. Upon shutdown, the init.d/halt script runs the quotaoff command RIGHT before the filesystems are unmounted. The quotaoff command does not appear to update the aquota.* files with the information the kernel has in memory. I say this because the {a,c,m}times for the aquota.user file are only updated upon a reboot of the system or by manual running the quotacheck command. It appears - as far as I can tell - that the kernel just drops it's up-to-date usage data on the floor at shutdown. This information is never used to update the aquota.* files. They are updated during startup by quotacheck(rc.sysinit). Seems silly to me since that updated info had already been collected by the kernel. So...in conclusion I am still not entirely clear on the methods. ;)

  • Standalone tool to synchronize two folders in windows?

    - by Jim
    I keep data on a USB drive, but I also keep a copy of all of that data on a hard disk. I like using the hard disk because it's faster and gives me a backup. What standalone tools would work to keep the files on the disk and USB drive in sync? I'd like a single command line executable or standalone GUI app that can do the job--something I could run off of the USB drive. So, things like the MS Sync Tool wouldn't work.

  • How can I detect hard drive failures?

    - by Francis
    I am in charge of a large number of Windows servers. Recently, many have been reporting hard drive errors with event codes 11 and 55. CHKDSK indicates that the drives are fine most of the time. What other diagnostic tools could I use to more accurately detect hard drive failures? Could these Windows events be false positives? I have already evaluated S.M.A.R.T., and it seems to have significant sensitivity and specificity issues.

  • How would I recognize the "spoon-feeding problem" on a dynamic webapp server?

    - by Don Spaulding
    The "spoon-feeding problem", as it was recently explained to me, happens when connections to your application server are tied up feeding data across slow network connections to your clients. This makes sense to me and now I understand the importance of putting a highly-concurrent proxy in front of my app servers. My question is, how did the first person to recognize this problem figure it out? What *nix tools and troubleshooting techniques would help me to recognize this problem if I hadn't had it explained to me?

  • How to restrict Windows 7 internet data usage while using mobile connection?

    - by Daniel Gehriger
    When I'm travelling I would like to use my iPhone's mobile hotspot feature to provide Internet access for my Windows 7 laptop. However, my mobile data plan has a limit on the amount of data I can use per month, and I would like to restrict Internet access to a few very specific applications (such as a database administration tool and Chrome). Is it possible to create a firewall profile for use with mobile data access? If not, what tools exist that could assist me?

  • How can I delete rest of the line after a specific string?

    - by nixdagibts
    I'm looking for a way to search for a specific string e.g. '=UUID:' and delete it and all following characters per line. I would prefer a way/macro/addon for notepad++. But all other tools or scripts are welcome :) Before *://81.88.22.6/*=UUID:63969B2469B7A94EBBDBD7CB5B9C00BA *://*-ad.cgi*=UUID:3C8EFF48B674CC42BF5B6E2B7BA820E7 *://*-ads/*=UUID:0D6CF7D5BE3F034C8A136CC99A074406 Note that the numbers are always different per line so you couldn't do a search 'n replace with them. Should look like this after *://81.88.22.6/* *://*-ad.cgi* *://*-ads/*

  • Buttons vanishing from Visual Basic Toolbar

    - by Brian Hooper
    I'm using Microsoft Visual Basic 6 and am having trouble with the toolbar. Several buttons have recently vanished from the toolbar, and replacing them with the View-Toolbar option only worked temporarily. Now, however, the Toolbar button has disappeared off the View menu, and the Customize button has likewise vanished from the Tools menu. Does anyone know what the problem is, or where I can find out how to correct this?

  • Bootable backup of a Mac without an HFS+ disk?

    - by marienbad
    How can I make a bootable backup of my Mac's internal hard drive to be restored using Disk Utility, without formatting my external destination drive as HFS+ (it's FAT32, of course)? Time Machine and SuperDuper both require that the volume where the backup is saved be HFS+ formatted. This looks helpful: http://developer.apple.com/macosx/backuponmacosx.html But it doesn't explain how to use FAT32 disk.

  • Multiple [Stand-alone] zip files creation?

    - by im_chc
    How can I automatically zip a group of files into multiple zip files (say, 2mb in size for each file), and that each zip file is a stand-alone zip file? (i.e. not mult-volume zip files, that you can't lost any one of the files, otherwise you can't unzip) Is there any tools available to do so? Actually I just need to group the files into many groups, 2mb each etc, zipped or not zipped doesn't matter thx!

    I am a developer looking for an opportunity to get a graduate degree. Since I don't have problem with English, I would like to find an online course available remotely to an international student like myself. As long as I can use my English, I don't have strict preference to US institute over other places. Can anyone suggest me a good course or a portal-like place where I can find good information?

  • Remote deployment of OS X Mountain Lion 10.8 upgrade, not as a fresh install

    - by Dean A. Vassallo
    Anyone have any ideas or suggestions (or know if its even possible) to remote upgrade a fleet of Macs from 10.6.8 to 10.8 remotely. I presume I can push the installESD through ARD, but I want it to run completely unattended. If it is not possible through "traditional" methods does anyone know of any tools that might help automate this process? Thank you for your thoughts, feedback, and suggestions.

  • Can capistrano or fabric be used to setup a server from scratch?

    - by Blankman
    I'm hoping there is a light weight, command line utility that I could use to setup a server from scratch. I like python's fabric or ruby's capistrano but from what I was reading they are more used for deployment purposes and not setting up apache, mysql, update patches etc. I know there are other tools like puppet, but I don't want to setup a master/slave for servers etc., I was hoping there was a more light-weight tool for this.

  • web services access not being reached thru the web browser [closed]

    - by Tony
    I am trying to reference my .asmx webservices in .NET but my server is not exposed to the internet. When I put on the following address I get the message mentioned below. What's the reason for not being able to see the directory? Am I missing something in my IIS configuraction? Am I missing anything in my permissions? Just as reference I have other folders with webservices and I have the same issue. When I login to the server I am doing it with my windows user and password (I am using windows authentication). It's necessary to mention that when I put the URL I am getting a popup screen to put in my userid and password but it seems that's not able to validate since keeps asking me a couple of times. Let me know if you need more information to address this issue . http://appsvr02/Inetpub/wwwroot/DevWebApi/ Internet Explorer cannot display the webpage What you can try: It appears you are connected to the Internet, but you might want to try to reconnect to the Internet.

  • Monitoring folder diffs across servers with zabbix

    - by Marcus
    Problem: I want to make sure that a certain folder is equal regarding it's contents across my servers. I do not want an automatic filesync to keep them equal, changing is done manually. My initial thought was to once a day calculate some crc/hash on folder and send to Zabbix, and trigger when values differ. Is there any good tools out there that can calculate crc or similar of a folder? Anyone know of another solution that solves my problem?

  • How can be changed the linux system's default character set?

    - by JPCF
    Hi, I'm working in a software development team using svn. Since many developer's computers are working using windows, text file codification has to be agreed with everyone. I decided to use Linux, and probably I will have to change my machine's default character codification. How can this be done in Linux? Thanks

  • Tool to Set a Hotkey to Adjust Overlay Surface Gamma

    - by Synetech inc.
    I am looking for a (Windows XP) utility (preferably a standalone app) that can let me set a hotkey to adjust the gamma (and hopefully other color settings) of the overlay surface. ATI Tray Tools does not have the ability to bind the overlay color adjustments to the overlay. I’ve asked him about it and he said it was difficult to implement or something (he was kind of vague). The ATI Catalyst drivers do not have a hotkey function for the overlay tab either. Can anyone help?
