  • Is it possible for a directory to get unlinked while its contained files remain?

    - by Walkerneo
    I used to wonder why deleting directories via PHP or shell wasn't as easy as it was in Windows with just clicking delete. I realize now that deleting is simply unlinking files from the file allocation table, so to delete a directory, you must unlink all the files inside it. Is it ever possible for the directory's entry to be removed, but not those of the files inside it? Do operating systems periodically check for files that can't be reached in the file system?

    - by Crash893
    I had a pretty big scare when my company file server filled up. after tacking down the source I discovered that there is a .recycle folder that keeps ALL the files ever deleted (which is also hidden) Is there anyway to disable this feature? or periodically run a command that will delete all the junk?

  • Tool for logging NIC link state events.

    - by Alan B
    Intel NICs have a driver option (in Windows) that will log link state events to the system log, so if the network drops out periodically you can determine that fact. Does anyone know of a simple generic solution that does this, in other words one that is not part of the driver from a particular manufacturer? I know there are plenty of 'big iron' network monitoring tools out there but surely there's something really simple that runs as a service in Windows with minimal setup ? TIA

  • Local or public NTP servers?

    - by BeeOnRope
    For a relatively large network (thousands of hosts) - what are the arguments for and against running a locally managed (pool of) NTP server(s) (perhaps periodically set via some public NTP server) and having all other hosts on the network use that (pool of) NTP server(s) versus having all hosts simply use public NTP servers directly, say via ntp.pool.org? Aside from the pros and cons, What is typical best practice today?

  • Automatic backup software?

    - by Mehrdad
    Every backup software I've seen (even the ones that claim "continuous" protection) only backs up files periodically -- say, every 5 minutes. What I'm looking for is true continuous backup software, i.e. software that can transparently back up files immediately before they are written to, so that I can be certain I have all the versions of a file that ever existed. Is there any software that does this?

  • Does Tomcat or Jetty cache dynamic content?

    - by Continuation
    I'm working on a Servlet app with contents that are updated periodically. Hence, between updates any dynamic pages generated by the Servlet can be cached. Does Tomcat or Jetty (or any Servlet container) offer a way to cache dynamically generated pages? Or would I need to use a caching reverse proxy like Squid to accomplish that?

  • Create new vsftpd user and lock to (specify) home / login directory

    - by Geoff Jackson
    I need to periodically give temporary and limited access to various directories on a CentOS linux server that has vsftp installed. I've created a user using useradd [user_name] and given them a password using passwd [password]. I've created a directory in /var/ftp and then I bind this to the directory that I wish to limit access to. What else do I need to specifically do to ensure that when this user logs into FTP, they only have access to this directory please?

  • Are there freezing issues with the Seagate Barracuda ST31500341AS anymore?

    - by Neil
    I found this hard drive on NewEgg: Seagate Barracuda 7200.11 ST31500341AS 1.5TB 7200 RPM 32MB Cache SATA 3.0Gb/s 3.5" Internal Hard Drive (bare drive) - OEM http://www.newegg.com/Product/Product.aspx?Item=N82E16822148337 And there are quite a few substantial bad reviews about the drive freezing periodically. If you search for a bit, you can find several forums with people having problems, but of course forums don't get updated when resolutions to those problems are found. I'm just wondering, does anyone know what the final verdict regarding the freezing issue with these hard drives is?

  • SQL Server 'Real Time' Mirroring Possible?

    - by Ryan
    We have a SQL Server that has important databases for our clients, if the server goes down we want another server to be ready to be switched over (we would just change the IP). The question is, how can we automatically sync the primary SQL Server to the secondary one periodically through out the day? Or even in real time? Thanks!

  • Can you disable the Ctrl-S (XOFF) keystroke in Putty?

    - by Seth
    I do a lot of ssh-ing, and periodically I hit Ctrl+S, which naturally sends an XOFF, and causes all kinds of problems (not to mention it takes a while for me to figure out what happened, then another while to remember that I need to press Ctrl+Q to recover. I would much rather instruct Putty to never ever let me type XOFF. Any ideas?

  • How can I get "Calculated Columns" to work in excel?

    - by Shawn Persels
    Using Excel 2010, I want a single formula to apply to all cells in a column. I see documentation for a feature called "Calculated Columns". That is exactly what I want, but when I follow the instructions I only end up creating a formulate in a single cell - not the whole column. I don't want to use "Fill" or "Copy" because the number or rows in the sheet changes periodically and maintaining the formulas would be very tedious.

  • How to get scrolling plot in Linux (using command-line tools)?

    - by Vi
    Supposing I have a program that prints lines with data periodically, how can I turn then info them into graphical plot that updates itself each time new line available? $ ./prog 10 44 20 66 30 55 40 58 50 59 55 58 60 77 ^C $ ./prog | scrollingplot Window appears and updates on each line printed: 80| | ---- | ---- ______...__/ | / ----- | - 40| ------------------------------- 10 20 30 40 50 60 # Note that ASCII art-style plot is just for example, # I want simple X window like in mplayer. There are enough tools for static data, but I haven't seen ones for updating data (except of ksysguard).

  • What is the Windows analog of the Linux watch command?

    - by PeterJCLaw
    I'm looking for a Windows program/script/command line function that works like Linux's watch program. watch periodically calls another program/whatever and shows the result, which is great for refreshing an output file or similar every second: watch cat my-output.txt or, more powerfully: watch grep "fail" my-output.txt I've looked for it in cygwin's library, but it doesn't seem to be present.

  • Help Prevent Carpal Tunnel Problems with Workrave

    - by Matthew Guay
    Whether for work or leisure, many of us spend entirely too much time on the computer everyday.  This puts us at risk of having or aggravating Carpal Tunnel problems, but thanks to Workrave you can help to divert these problems. Workrave helps Carpal Tunnel problems by reminding you to get away from your computer periodically.  Breaking up your computer time with movement can help alleviate many computer and office related health problems.  Workrave helps by reminding you to take short pauses after several minutes of computer use, and longer breaks after continued use.  You can also use it to keep from using the computer for too much You time in a day.  Since you can change the settings to suit you, this can be a great way to make sure you’re getting the breaks you need. Install Workrave on Windows If you’re using Workrave on Windows, download (link below) and install it with the default settings. One installation setting you may wish to change is the startup.  By default Workrave will run automatically when you start your computer; if you don’t want this, you can simply uncheck the box and proceed with the installation. Once setup is finished, you can run Workrave directly from the installer. Or you can open it from your start menu by entering “workrave” in the search box. Install Workrave in Ubuntu If you wish to use it in Ubuntu, you can install it directly from the Ubuntu Software Center.  Click the Applications menu, and select Ubuntu Software Center. Enter “workrave” into the search box in the top right corner of the Software Center, and it will automatically find it.  Click the arrow to proceed to Workrave’s page. This will give you information about Workrave; simply click Install to install Workrave on your system. Enter your password when prompted. Workrave will automatically download and install.   When finished, you can find Workrave in your Applications menu under Universal Access. Using Workrave Workrave by default shows a small counter on your desktop, showing the length of time until your next Micro break (30 second break), Rest break (10 minute break), and max amount of computer usage for the day. When it’s time for a micro break, Workrave will popup a reminder on your desktop. If you continue working, it will disappear at the end of the timer.  If you stop, it will start a micro-break which will freeze most on-screen activities until the timer is over.  You can click Skip or Postpone if you do not want to take a break right then. After an hour of work, Workrave will give you a 10 minute rest break.  During this it will show you some exercises that can help eliminate eyestrain, muscle tension, and other problems from prolonged computer usage.  You can click through the exercises, or can skip or postpone the break if you wish.   Preferences You can change your Workrave preferences by right-clicking on its icon in your system tray and selecting Preferences. Here you can customize the time between your breaks, and the length of your breaks.  You can also change your daily computer usage limit, and can even turn off the postpone and skip buttons on notifications if you want to make sure you follow Workrave and take your rests! From the context menu, you can also choose Statistics.  This gives you an overview of how many breaks, prompts, and more were shown on a given day.  It also shows a total Overdue time, which is the total length of the breaks you skipped or postponed.  You can view your Workrave history as well by simply selecting a date on the calendar.   Additionally, the Activity tab in the Statics pane shows more info about your computer usage, including total mouse movement, mouse button clicks, and keystrokes. Conclusion Whether you’re suffering with Carpal Tunnel or trying to prevent it, Workrave is a great solution to help remind you to get away from your computer periodically and rest.  Of course, since you can simply postpone or skip the prompts, you’ve still got to make an effort to help your own health.  But it does give you a great way to remind yourself to get away from the computer, and especially for geeks, this may be something that we really need!

  • Securely sending data from shared hosted PHP script to local MSSQL

    - by user329488
    I'm trying to add data from a webhook (from a web cart) to a local Microsoft SQL Server. It seems like the best route for me is to use a PHP script to listen for new data (POST as json), parse it, then query to add to MSSQL. I'm not familiar with security concerning the connection between the PHP script (which would sit on a shared-host website) and the local MSSQL database. I would just keep the PHP script running on the same localhost (have Apache running on Windows), but the URI for the webhook needs to be publicly accessible. Alternately, I assume that I could just schedule a script from the localhost to check periodically for updates through the web carts API, though the webhooks seem to be more fool-proof for an amateur programmer like myself. What steps can I take to ensure security when using a PHP on a remote, shared-host to connect to MSSQL on my local machine?

  • What units does the ntp drift file use?

    - by arielf
    When the ntpd daemon is running, the file: /var/lib/ntp/ntp.drift gets updated periodically. Example: 17:20 hostname 118 ~> ls -l /var/lib/ntp/ntp.drift -rw-r--r-- 1 ntp ntp 7 May 20 16:46 /var/lib/ntp/ntp.drift # So it looks like it was last updated ~34 minutes ago The file has one number in it, for example, looking at a 4 virtual hosts, I find these values, respectively: -22.086 -10.214 -13.669 6.045 I assume these are seconds per day(?), but not sure. man ntpd mentions a different drift file /etc/ntp.drift which doesn't seem to exist. The man page doesn't explain what units are being used for the drift. Questions: Is /etc/ntp.drift actually /var/lib/ntp/ntp.drift on Ubuntu? What units is the drift expressed in? Thanks!

  • Getting bank account information from a bank and displaying on a website [closed]

    - by Ali Syed
    Hello I am looking for a way to get bank account information (transactions and balance) from a financial institution and display it on a website. The question is vague intentionally.... Everything is open. I haven't chosen a bank, serverside technology or front end technology. The idea is to have a script run automatically periodically (once or twice a day) and get the latest account information from the bank server automatically. Probably something in the direction of OFX (Open financial exchange), HBCI (home banking c.. interface), fnts or something like it. Even working over a closed source API is not out of question: Wesabe or Mint or something. Paypal is not an option because it won't work in India or Pakistan. cheers *Explanation: I have an exclusive small club. My members make irregular payments. These transactions should be online for all MEMBERS (with login) to see *

  • Accidentally Uninstalled Ubuntu Desktop and Anacron. Reinstalled. What Can I Expect?

    - by Volomike
    Unfortunately when I installed the cron package to take a look at it, I didn't realize that I was also uninstalling Ubuntu Desktop and Anacron. Crap!!! So, I then did apt-get install anacron ubuntu-desktop, which also removed fcron. However, I need to know what instability issues I may now encounter because I have done this change and changed it back. I mean, now that anacron is back and ubuntu-desktop is back, am I out of the woods? Or, will I lose any important jobs that need to run periodically from anacron?

  • Synchronizing local and remote cache in distributed caching

    - by ltfishie
    With a distributed cache, a subset of the cache is kept locally while the rest is held remotely. In a get operation, if the entry is not available locally, the remote cache will be used and and the entry is added to local cache. In a put operation, both the local cache and remote cache are updated. Other nodes in the cluster also need to be notified to invalidate their local cache as well. What's a simplest way to achieve this if you implemented it yourself, assuming that nodes are not aware of each other. Edit My current implementation goes like this: Each cache entry contains a time stamp. Put operation will update local cache and remote cache Get operation will try local cache then remote cache A background thread on each node will check remote cache periodically for each entry in local cache. If the timestamp on remote is newer overwrite the local. If entry is not found in remote, delete it from local.

  • Prevent APT from overwriting JCE jars

    - by Doc
    My server runs a Java application that requires I replace a few java library files with ones I downloaded on my own. This has to do with JCE security extensions and isn't really relevant to my question. I've found that these library files tend to get overwritten by apt when it later updates my java package. Is there a apt-friendly way of masking these specific files so apt won't touch them? Potential Solutions I'm considering just removing the write flag from the files, though I'm expecting this will cause apt to spew its guts everywhere when it later tries to overwrite them? Perhaps there's a java custom library directory I don't know of, where I can park my files and they'll be loaded instead of the package's defaults? The last-resort option I'm considering is writing a cron job to periodically replace the files with my versions. I hate this option.
