  • Does lighter wallpaper consumes lesser power than a Darker one

    - by Lamb
    My VAIO advised me to switch to a White Background, to reduce power consumption. But it seems contradictory to common logic. Its like saying a brighter Torch consuming less than a dimmer one. Common Logic says that, Screen is BLACK when not using any POWER, so displaying black color should not consume any power (because without powering any pixel it gives black color) Also a white screen gives me more light than a darker one, so it should use more Energy. White Wallpaper = More Light Output = More Electrical Energy Consumed Black Wallpaper = Less Light = Less Electricity Consumed My question is - Is there anything wrong with the above argument ? A Lighter Wallpaper consumes less power than a Darker one. Is it true ? If yes, Why ?

  • Deleting large no of files on linux eats up CPU

    - by Sanjay
    I generate more than 50GB of cache files on my RHEL server (and typical file size is 200kb so no of files is huge). When I try to delete these files it takes 8-10 hours. However, the bigger issue is that the system load goes to critical for these 8-10 hours. Is there anyway where I can keep the system load under control during the deletion. I tried using nice -n19 rm -rf * but that doesn't help in system load.

  • Killing all processes of current user

    - by Vi
    user@host$ killall -9 -u user Will it definitely kill all processes owned by user (including forkbombs)? No new processes is spawned to user from other users. No user's processes are in D-sleep and unkillable. No processes are trying to detect and ptrace or terminate this started killall. E.g. if killall will finish untampered and successfully is it 100% that no processes are left with this uid?

  • where are the "ipmi sel" entries parameter descriptions?

    - by Horatiu
    In order to troubleshoot a possible hardware issue I have installed ipmitools on my server and am doing queries for info related to poweron/poweroffs, hardware added/removed/status. I am trying to find some info on how to interpret sel obtained via ipmi sel list and the output looks like this : 72b4 | 10/31/2013 | 10:42:40 | System Event #0x01 | OEM System boot event | Asserted 72c8 | 10/31/2013 | 10:42:48 | System ACPI Power State #0x82 | S0/G0: working | Asserted I really want to know what "Asserted" means in this context, and also, where can I find a reference with all possible "exit status(es)" ? (Because I think that's what this is, right ?)

  • lwp-rget changes file format automatically to .bin?

    - by Hector Tosado Jimenez
    Im trying to recursively get an html page to get everything that's there and save it to my directory. Lwp-rget from perl allows me to do this but I'm having the problem that its getting all the files and changing them from .rpm, .xml, .html, etc to .bin. I've been trying to maybe use the --keepext=application/xml or any type but it continues to save the file as .bin. Any way I can stop that auto formatting? Thanks.

  • apt-get for a package with when "contrib/source/Sources" is not found correctly

    - by Stuart Woodward
    I tried to install Webmin on Ubuntu by following the instructions on http://www.webmin.com/deb.html. Using the Update Manager GUI I added the repositories and the key deb http://download.webmin.com/download/repository sarge contrib deb http://webmin.mirror.somersettechsolutions.co.uk/repository sarge contrib However when I do an: apt-get update apt-get install webmin I get the error: W: Failed to fetch http://download.webmin.com/download/repository/dists/sarge/Release Unable to find expected entry 'contrib/source/Sources' in Release file (Wrong sources.list entry or malformed file) W: Failed to fetch http://webmin.mirror.somersettechsolutions.co.uk/repository/dists/sarge/Release Unable to find expected entry 'contrib/source/Sources' in Release file (Wrong sources.list entry or malformed file) Looing at the page at the URL I can see: 7029066c27ac6f5ef18d660d5741979a 20 contrib/source/Sources.gz Is the error caused by the fact that the Sources are compressed with gzip or am I doing something wrong?

  • What's a good way for organizing PDF documents on windows?

    - by Ivan
    I'm looking for a good way to manage a lot of pdf documents (e.g. papers, ebooks) on windows. Ideally I'm looking for a windows version of the great mac app Yep. I've looked quite a bit and haven't found any windows app that provides and organized overview of your pdf documents. I've considered just tagging the pdf files, but there don't seem to be any apps to simply tag and search tagged files easily. I've found TaggedFrog, but the tags are kept in the app's internal DB and are associated with the filename. So if you move/rename a file it looses all its tags. In a nutshell: Is there a good windows app to organize/efficiently tag files?

  • Sane patch schedule for Windows 2003 cluster

    - by sixlettervariables
    We've got a cluster of 75 Win2k3 nodes at work in a coarse grained compute cluster. The cluster is behind a mountain of firewalls and resides in its own VLAN. Jobs of all sizes and types run on the cluster and all of the executables running are custom-made. (ed: additional notes on our executables) The jobs range from 30 seconds to 7 days in duration, and may contain one executable or 2000 sub-jobs (of short duration). Obviously we are trying to avoid the situation where our IT schedules a reboot during a 7 day production job. We have scheduling software which accomodates all of the normal tasks for a coarse grained cluster and we can control which machines are active for submission, etc. If WSUS was in some way scriptable (or the client could state it's availability for shutdown) we could coordinate the two systems and help out. Currently, the patch schedule is the Sunday after Super Tuesday regardless of what is running on the cluster. We have to ask for an exemption every time we want to delay patching a machine for a long running production job. Basically, while our group is responsible for the machines we have little control over IT's patch schedule. Is patching monthly with MS's schedule sane for a production Windows cluster? Are there software hooks in WSUS where we could say, "please don't reboot just yet"?

  • Setting charging limit on MBP?

    - by Giannis
    Is it possible to tweak settings so that the battery will only charge up to 90% -95% and then use power adapter to run ? A friend told me he was able to set such limits on his non-mac PC so I was hoping there would be a way to do it. From reading I have done online it appears this is better than having a 100% battery most of the time. I have an MBP 13" 2012 running latest version of OSX ML(10.8.2).

  • Why Does My Windows 7 PC Freeze After Waking from Sleep?

    - by Blaenk
    Hey guys. I have Windows 7 running on my computer and everything is perfect. There's only one little problem. Sometimes when I leave my computer, I come back and my monitor is turned off or asleep, whichever it is. This is fine, I set it to do this. However, after turning on the monitor and moving the mouse around, the mouse cursor freezes; both the keyboard and mouse don't respond to anything, for example the keyboard's windows key won't bring up the start menu and moving the mouse around does not move the cursor around on the screen. I have to wait about a minute or two before things start working again. I figured this was a power savings setting problem, so I went into Control Panel Power Options. I only have Turn off Display = 30 minutes and Put Computer to Sleep = Never. Of course, I went into the advanced power settings to look through there. I put Never to turn off the hard disk, Sleep after never, and that's about it. Nothing else there looks like it might be causing this. I went into the device manager and checked the mouse and the keyboard, and they both have the Allow this device to wake the computer checked for both of them. Perhaps this other bit of information might help: Sometimes I VNC into my PC using my MacBook, and sometimes, as soon as it shows me the desktop, the same thing happens. The mouse won't move and VNC won't register any events on the server (Which is my PC of course). I close the client (And I know it has nothing to do with the client), then immediately restart it and try to connect. When I click the connect button, it hangs there, as if the PC is not responding. Basically it's like whenever I try to wake the computer from sleep, it does so by showing me the desktop, then it freaks out. Then again, I guess the computer isn't sleeping because the setting is set to 'Sleep after = Never'. I honestly don't know what's going on, would appreciate any insight. Thanks!

  • In Linux, are there any plug-ins to let me do `<Win>`+`<Num>` style app switching (like Windows 7's superbar)?

    - by kizzx2
    Using Windows 7's superbar, I can select/launch the 2nd application group by <Win>+<2>. We have DockbarX in GNOME, which is nice (grouping the windows like Windows 7), but it doesn't enable the <Win>+<2> style keybaord shortcuts. Any suggestions? This is not restricted to making Linux like Windows. But I just find the <Win>+<2> style shortcut very useful. Are there similar ways in Linux to quickly switch between specific apps without pressing <Alt>+<Tab> many many times?

  • Fujitsu Siemens V6535 laptop doesn't wake up - crash when going into standby?

    - by marc
    I'm having trouble with my laptop (Fujitsu Siemens model V6535). It runs Windows 7, and after I upgraded from Vista I've noticed something that makes me really angry. When my laptop goes into Standby, the power LED changes to red and starts blinking (standby mode). When I push the power button to wake it up it, the blinking LED changes to green but nothing else happens. Nothing on the display, no HDD sound. When I press the power button for a few seconds and then try turn it on again, it doesn't display anything. I have to unplug the charger, shut it off, and power it on again without the power cable. Then it starts working. A few days ago I upgraded the BIOS to the newest version, but it doesn't help. Does anyone have any idea what can be wrong?

  • Portable and Secure Document Repository

    - by Sivakanesh
    I'm trying to find a document manager/repository (WinXP) that can be used from a USB disk. I would like a tool that will allow you to add all documents into a single repository (or a secure file system). Ideally you would login to this portable application to add or retrieve a document and document shouldn't be accessible outside of the application. I have found an application called Benubird Pro (app is portable) that allows you to add files to a single repository, but downsides are that it is not secure and the repository is always stored on the PC and not on the USB disk. Are you able to recommend any other applications? Thanks

  • Workflow: suggest a versioning and file control for Designer and Developer

    - by Pennf0lio
    Our company are having hard time managing project files and managing versions of PSD, HTML, PHP, and CSS files. Can anyone recommend a good software or workflow to handle files and versions. Here's my common scenario: I work for a project in my computer, it could be a Website mockup or a coding project. I then save all the files locally in my workstation. I'll then upload all the project files in the server connected in our network to have a backup. In my files, I usually append a "r1" for revisions, like "WebsiteMockup_r1" or "WebsiteMockup_r2". I need somehow to synchronize all my local files to the server and have some versions options.

  • Top ten security tips for non-technical users

    - by Justin
    I'm giving a presentation later this week to the staff at the company where I work. The goal of the presentation is to serve as a refresher/remidner of good practices that can help keep our network secure. The audience is made up of both programmers and non-technical staff, so the presentation is geared for non-technical users. I want part of this presentation to be a top list of "tips". The list needs to be short (to encourage memory) and be specific and relevant to the user. I have the following five items so far: Never open an attachment you didn't expect Only download software from a trusted source, like download.com Do not distribute passwords when requested via phone or email Be wary of social engineering Do not store sensitive data on an FTP server I have two questions: Do you suggest any additional items? Do you suggest any changes to existing items?

  • Is there a list of Windows services that can be turned off to save resources?

    - by scunliffe
    Every time I open up my task manager and look at the tasks running, it appears to me that there has got to be a bunch of junk running in there that I don't want or need and would be better off turning off (e.g. set the service to manual vs. automatic) In particular I'm running Windows XP, but I'd be interested in services for any version. e.g. Service: ThinkPad PM Service What is it: The ibmpmsvc.exe process is installed by default on IBM Notebook computers. It allows various functions of your IBM notebook to be controlled using the blue Fn keys. If you use the blue Fn keys on your Notebook, you should leave this process running. Otherwise, if it is causing problems for your system you should terminate the ibmpmsvc.exe process. (source) Thus for me, (having never used, or intending to use these buttons) - I want to turn it off. There's lots that just seem painfully unnecessary to me... I'm just not sure which ones I can "safely" stop/disable without issues... "Alerter", "ClipBook", "Messenger", "Telnet", "ATI Hotkey Poller", "Office Source Engine", etc. I'd appreciate any info on services that are truly unnecessary, or only useful to certain people/types of users.

  • Fixing/Extending Standard Windows File Open/Save Dialog [closed]

    - by scunliffe
    Possible Duplicate: Change left side link of the Save As Dialog for a DropBox one? Almost every time I use the standard Windows (XP) File Open/Save Dialog I get frustrated in how long it takes me to navigate to where I want to go. :-( (I won't even get into the MS Office dialog that makes things even worse) This is the dialog I'm referring to (with some notes) Notes: Wouldn't a Drive list be handy in here? C:\, D:\, E:\, etc. What about a breadcrumb URI? (the magenta list of links) Why isn't Program Files one of the icons on the left? (green) I'm always going in there for something Why can't I type "../../../" to navigate up multiple directories in the File name box? (blue) There has got to be some utilities out there that can "hijack" or "overwrite" this core windows dialog to provide a much better set of options. I'm looking for any/all solutions to help fix this dialog.

  • Is there a way to prevent password expiration when user has no password?

    - by Eric DANNIELOU
    Okay, we all care about security so users should change their passwords on a regular basis (who said passwords are like underwear?). On redhat and centos (5.x and 6.x), it's possible to make every real user password expires after 45 days, and warn them 7 days before. /etc/shadow entry then looks like : testuser:$6$m8VQ7BWU$b3UBovxC5b9p2UxLxyT0QKKgG1RoOHoap2CV7HviDJ03AUvcFTqB.yiV4Dn7Rj6LgCBsJ1.obQpaLVCx5.Sx90:15588:1:45:7::: It works very well and most users often change their passwords. Some users find it convenient not to use any password but ssh public key (and I'd like to encourage them). Then after 45 days they can't log in as they forgot their password and are asked to change it. Is there a way to prevent password expiration if and only if password is disabled? Setting testuser:!!:15588:1:45:7::: in /etc/shadow did not work : testuser is asked to change his password after 45 days. Of course, setting back password expiration to 99999 days works but : It requires extra work. Security auditors might not be happy. Is there a system wide parameter that would prompt the user to change expired password only if he really has one ?

  • Move some iTunes library items to different drive?

    - by Sören Kuklau
    My internal hard drive is somewhat small, and I only regularly listen to a fraction of my iTunes library anyway, so I'd like to keep large portions on it on an external drive for archival purposes. Since dealing with multiple iTunes libraries is somewhat painful, the solution I'm looking for is to move individual items of the library to a different location, without compromising the "Keep organized" and "Copy files" settings. I found an AppleScript that I assume is supposed to do this, Move Files To Folder…, but it instead copies them, and doesn't update the library accordingly. I can do this manually by moving the file, then accessing it in iTunes — it'll prompt me for the new location. I just don't intend to do this one by one for thousands of files.

  • How do I enable additional debugging output from Ansible and Vagrant?

    - by Brian Lyttle
    I'm investigating Ansible for server and application provisioning. My application is currently provisioned with shell scripts in Vagrant. Rather than rewrite my scripts I've taken a sample and attempted to deploy it. It appears to deploy fine, but I've seeing a failure message after what looks like a series of successful steps: » vagrant provision ~/vm/blvagrant 1 ? [default] Running provisioner: ansible...

  • organizing my music and my itunes

    - by Cawas
    What can we do to organize our music? I've got over 20k items on my iTunes Library, at least 5k with ratings and play counts, apparently just 12k music files and I can't understand how this question have not been properly answered yet. Maybe there is no answer. I have too many duplicates, broken links, bad music, corrupted files... Well, a big mess with no tags! Probably there's no single software capable of just organizing everything, though I'd love one. Hopefully some time in the near future we all will be able to just sync the cloud of our automagically selected music to the newly created offline copy. But meanwhile... Please, do consider I've at least gave a shot (even while not a full test drive) to every single answer linked here already, plus a few more. I'm fine with using other software (mac too, please) to organize, but I'd need it to sync (retrieve and put back) at least iTunes ratings, because of iPhone and smart playlists. Not looking for iTunes replacement. I'm hoping to hear what you hardcore music organizers out there are using as your own solutions! :) I myself am using way too many tools, getting way too little done and end up going song by song.

  • Making it Easier for Older Users to Login to Multiple Accounts

    - by Mike Hagstrom
    I currently do consulting for a small business that has multiple applications that they need to login too. I'm trying to get them to start using Basecamp and Zendesk to make all of our lives easier when it comes to collaboration on big projects and quick helpdesk ticket items. However, I have recently been informed that it is difficult for them to remember all of these websites etc... to login too. However the login information is the same. Right now they have to login to: Windows Login Gmail I want them additionally to login to Basecamp Zendesk This is just a generation or two gap between myself and them, so I'm wondering what others do to solve these problems. Is there some way we could configure USB thumbdrives that somehow have Lastpass or something on that when plugged into the computer automatically log them into their Windows account, then when they were to say visit the Basecamp account would automatically log them into that? I think the security risk (of a list thumbdrive) is well worth the ability to use these extra applications. Unless anyone else has any other ways for making it easier for users to login to multiple sites.
