• hardware: delay and distinct 'click' before hard drive access

  - by matt lohkamp

  I have a windows 7 box stashed away in my closet, containing (among other things) 2 big HDDs linked together as a mirrored volume - basically a super lazy NAS / media server. I've noticed that when that drive is accessed (whether locally, on the machine itself, or remotely, from another computer, or my xbox, for example) there's a noticeable pause, and then from the computer itself, a 'click!' noise, after which the drive is accessed; e.g. open \\computername\shared\, wait 2 seconds, hear 'click!' and then see files appear in windows explorer. Any ideas? Otherwise the drive preforms normally - is it a windows thing? a HDD-about-to-die thing? Or a "yeah that always happens, you've just never noticed it before" thing?

• Can I do an overwrite install of Windows 7 without losing all my apps and data?

  - by Brian Dougan

  My local computer technician installed his store's copy of Window's 7 Premium on my computer. I had been using Window's Vista; but needed the XP component of "7" As part of the price I paid; I have a fully licensed, unopened "7" disc; with all of the drivers included. The technician warned me about the "nag" screen; that asks me to install my licensed copy at any time. Without thinking; I downloaded all of my usual software programs before installing the licensed copy. Here is my question: I hope this won't sound obvious: Will it overwrite my downloads?

• Job queueing in Toast Titanium 10?

  - by moonslug

  I have a bunch of .MP4 video files I'm burning to DVD-Video using Toast Titanium 10 on my MacBook Pro. Right now, I'm doing them one at a time. Because my computer is several years old, encoding video for a single DVD takes approximately six hours. I've discovered that it appears I can encode the video directly to a .toast format — however, I have yet to figure out if I can burn these directly to DVD. Also, I have quite a bit of video left to burn, and even that method would require me intervening manually to start a new encoding or burn job every six hours. Would it be possible to somehow queue up multiple DVD-Video encoding jobs at once, and have the computer work through them automatically? The actual writing to DVD disc doesn't take nearly as long, and if I had all my video encoded for me to begin with my job would be a lot quicker. Maybe this can be accomplished with a different piece of software?

• Laptop white screen on power-up. Still displays via HDMI output

  - by Inno

  my wife's laptop recently started displaying a white screen. It doesn't show post or anything, just a white screen when it's powered on. However, it works normally with HDMI output to our television. I took it apart and fiddled with both ends of the display cable, but I either didn't fiddle correctly or that's just not the problem. I also noticed that the screen won't turn off anymore when the laptop is closed. Is there a name for the mechanism that controls this function, so I can try and locate it? My guesses are that the problem lies with the screen itself or the display cable, but I'm curious if there's anything else I might be overlooking. Also of note is that the left hinge is partially broken. The corner of the plastic computer case broke off, so the hinge is exposed and doesn't stay in place. I've tried holding it in place, wiggling it around, tapping various parts of the computer, but the white screen remains.

• How can I clear the "authentication cache" in Windows 7 to a password protected samba share?

  - by Chris Drumgoole

  I have a Linux samba server and have explicitly listed users that can access the folder. I have successfully congfigured Samba to require a username and password when accessing the share from windows (using the smbpasswd, etc.). But now I want to force clear the auth cache on the windows machine. Such as when I go to a colleague's computer, I use my account to access a file in the protected share, but then before I leave his computer, i'll want to make sure the authorization cache is cleared so he cannot access that folder with my credentials. I found the command to use in the windows command prompt on google a couple of weeks ago but silly me I didn't save it... Hope someone can help, thanks! Oh, Samba is configured as a workgroup and not a domain (if that helps) - so windows users do NOT log into a domain on start up. thanks!

• Are some .ogv/.ogv files possible to be corrupted, to make it not possible to loop?

  - by C15R

  I discovered by trial and error that my one .ogv video will not loop, but if I interchange a random .ogv video from wikipedia that one does loop, and they are both called .ogv. Why is this? Is the not-looping file corrupted? EDIT! I just had a breakthrough! I discovered if I view the webpage using my computer's version of the file (not-uploaded version), then it does loop! (I open index.html on my computer, and it is a relative URL) But! The version which is uploaded onto my web server does not loop. (I changed the relative URL to an absolute URL which points to the file on my server. I tried re-uploading it, but still does not loop. If someone has an answer to why this is and how I can fix it, I will be very grateful!

• Remote connection to dynamic public ip & private ip addresses

How could I remotely connect from my office to the 'vista system'?. If I've a router/modem at my home it may be possible to allow the ports for the system but I don't. Any tips?

• Avoid cache overflow in Atempo LiveBackup

  - by Vebjorn Ljosa

  When attempting the initial backup of a new client, Atempo LiveBackup seems to require a very large cache. For instance, a 20 GB cache is not enough to back up a computer that has 100 GB of data. It appears that LiveBackup is adding new files to the cache at a faster rate than it can send them to the server. When the cache fills up, the backup fails. Aside from removing most data from the computer and then add them back gradually after the initial backup, is there a good workaround? Is it possible to make LiveBackup slow down its scan so as to not fill the cache? Or is it possible to place the cache on an external drive?

• The good SQL database to process a lot of data?

  - by Dorian

  I have to process like 10-100 millions records. I have to give the data to the client when it's finish. The data is givent as SQL requests to execute in the database. He have a powerful server with MySQL, I think it will be fast enough. The issue is my computer is not as powerful as his server, so I would like to use an other SQL server who is compatible (I export his database and import it in my computer) with MySQL but more powerful. What should I use? Or am I doomed to use MySQL?

• Updating, etc., automatically

  - by Steve D

  Is there a way to set up Ubuntu 12.04 (or earlier versions) so that all recommended updates are done automatically, say once a week? When I say automatically, I mean no password entry or user intervention required. This sounds like a stupid request, so let me tell why I'm asking. My grandfather knows nothing about computers; he uses his solely to read Yahoo! mail. I want to get rid of his clunky, spyware-ridden Windows XP and install Ubuntu. I want to set it up so when he turns the computer on, after a couple minutes, voila!, Yahoo! mail, already signed in, ready to go. The problem is I don't want to have to go over there every week or so and make sure everything is up-to-date, he hasn't accidentally installed any spyware, etc. So can this be done? Is this the best way to set things up for my grandfather? Are there other things I should be worried about when it comes to keeping things hassle-free for him? Please don't post anything like "why not teach him how to... blah blah blah". My grandfather is 80 years old and has made it clear email is the only thing he will ever use a computer for! Thanks!

• Why does my general frame rate slow down to 40fps randomly?

  - by Joshua

  This has been bugging me for a while. Every once in a while, I find my computer to be sort of laggy and I thought it was because it was busy or something. However, I recently noticed that it wasn't any performance issue...I thought my computer was laggy because the frame rate slowed from 75fps right down to ~40 fps and caused very visible tearing. This is not rare. It happens many, many times a day. I have no idea what is happening...I have an AMD 5670 on Windows 7 32-bit by the way, and I've heard bad things about AMD's driver support. Could this be the problem? P.S. The frame rate slowdown is not just for games (I rarely play games, and have not played games in the time since I noticed this problem), it seems it's an issue for the entirety of Windows. I first noticed the tearing when I was moving around tabs in Google Chrome.

• Crap, hard disk failure. Can I recover my "move"d folders?

  - by Doug

  I am in the process of moving all my files from an old laptop to new one. I just moved 11gb of data from my old laptop to a hard drive (external) and then upon moving it out to the new hard drive, the hard drive is getting a CRC (Data Error (Cyclic Redundancy Check). Now I am looking for a solution to recover the files that I moved on my old laptop (not the external). I understand they they are just marked for potential overwriting to free up space. I was getting ready to test out GetDataBack, but it says to install it on a healthy windows and use the recover-needed drive as an external. However, I don't want to turn off my computer without first getting the okay since it is in a "moved" state. Please help! What can I do to recover the Moved files. I haven't touched the computer since it has been moved. What can I use to recover them?

• Sonicwall site-to-site can not access remote network

  - by vpnwizard

  I have 2 SonicWall devices (tz100) in 2 different geographical locations. They are connected to each other using site-to-site vpn connection and this works just great. Device A network - 192.168.1.0/24 Device B network - 192.168.2.0/24 When I connect to one device, I can access, from my computer, anything on that specific subnet. However, I am unable to view anything, from my computer, on the other network. Is there a setting somewhere that will forward my requests to the other subnet? Example - I VPN into Device A, but would like to get to a server which is on the Device B network (192.168.2.0/24)

• Windows XP Blue-Screens And Reboots Instantly On Boot-Up

  - by ashes999

  My computer was running perfectly until yesterday; my internet suddenly died. Being wireless, I decided to reboot; now the computer doesn't boot. It shows the "Starting Windows" screen (safe mode loads several drivers), then it suddenly blue-screens and immediately reboots (I cannot read the blue-screen contents at all). I've tried safe-mode (with and without networking); no dice. I booted another HD with another XP install and ran scandisk on my HDs; no bad sectors, and even with auto-repair, it didn't fix the problem. Now what? What are my options to fix the broken XP install? I'm thinking: 1) Remove wireless card 2) Run XP install CD and repair installation 3) ???

• What kind of eye wear can I use to protect my eyes from being irritated from staring at a screen all

  - by dr dork

  Many of us stare at computer screens all day. Lately, my eyes have been irritated from prolonged staring at my computer screens. Does anyone use or know of any eye wear technology that helps with this? About five years back, I bought a pair of non-prescription eye glasses that had a no-glare layer put on them by an optometrist. It slightly helped, so I'm considering getting another pair. Is this the best option I have at this point? Thanks so much in advance for your wisdom!

• How do I cluster strings based on a relation between two strings?

  - by Tom Wijsman

  If you don't know WEKA, you can try a theoretical answer. I don't need literal code/examples... I have a huge data set of strings in which I want to cluster the strings to find the most related ones, these could as well be seen as duplicate. I already have a set of couples of string for which I know that they are duplicate to each other, so, now I want to do some data mining on those two sets. The result I'm looking for is a system that would return me the possible most relevant couples of strings for which we don't know yet that they are duplicates, I believe that I need clustering for this, which type? Note that I want to base myself on word occurrence comparison, not on interpretation or meaning. Here is an example of two string of which we know they are duplicate (in our vision on them): The weather is really cold and it is raining. It is raining and the weather is really cold. Now, the following strings also exist (most to least relevant, ignoring stop words): Is the weather really that cold today? Rainy days are awful. I see the sunshine outside. The software would return the following two strings as most relevant, which aren't known to be duplicate: The weather is really cold and it is raining. Is the weather really that cold today? Then, I would mark that as duplicate or not duplicate and it would present me with another couple. How do I go to implement this in the most efficient way that I can apply to a large data set?

• Will I be able to get programming interviews at good software companies with a non-CS degree?

  - by friend

  I'll be graduating in a year, but I'll have a degree in Economics. I'm pretty much done with my Economics coursework, and by the time next year comes around I will have devoted 1.5 years to learning CS. I will have almost finished the requirements to graduate with a degree in CS, but unfortunately my school requires a science series that would add another 6-9 months of study if I were to try and get the degree (not to mention a max unit cap). I have or will have taken: Objected Oriented Programming Discrete Math Data structures Calculus through multivariable (doubt this matters at all) Linear Algebra (same) Computer Organization Operating Systems Computational Statistics (many data mining projects in R) Parallel Programming Programming Languages Databases Algorithms Compilers Artificial Intelligence I've done well in the ones I've taken, and I hope to do well in the rest, but will that matter if I can't say to the HR people that I have a CS degree? I'd be happy to get an internship at first too, so should I just apply as if I'm an intern and not looking for fulltime, and then try and parlay that into something? Sidenote if you have time -- Is a computer networks or theory of computation class important? Would it be worth taking either of those in lieu of a class on my list? edit -- I know this isn't AskReddit or College Confidential; I know there will be some outrage at posting a question like this. I'm merely looking for insight into a situation that I've been struggling with, and I think this is the absolute best place to find an answer to this question. Thanks.

• Unable to remove/hide icons from desktop folder

  - by Kyomu

  I wish to hide some windows icons from my desktop folder1, but cannot. When I click delete, it says they will be deleted from my desktop (which they already are), but they remain visible in the desktop folder, which is where I wish them removed. Is there any way I can remove these? (I always use Win+E which really lets me get to all of these easy enough). Offending icons: Libraries, Homegroup, User folder, Computer, Network, Control Panel, and Recycle Bin. For those who might be wondering why, I find myself in this folder a bit to often (including when uploading a file), and find these nothing but clutter, especially as these always default to the top. Thanks for your help! 1 By desktop folder, I mean the folder you would see by going to "My Computer" and clicking "Desktop" on the top left under Favorites. Note: Changing my "Desktop Icon Settings" under "Personalize" does not affect the desktop folder, but rather just the desktop view.

• Using command line to connect to a wireless network with an http login

  - by Shane

  I'm trying to connect to a wifi network where it hijacks all requests and redirects you to a page where you have to agree to a terms of use before it lets you connect to the actual outside world. This is a pretty common practice, and usually doesn't pose much of a problem. However, I've got a computer running Ubuntu 9.10 server with no windowing system. How can I use the command line to agree to the terms of use? I don't have internet access on the computer to download packages via apt-get or anything like that. Sure, I can think of any number of workarounds, but I suspect there's an easy way to use wget or curl or something. Basically, I need a command line solution for sending an HTTP POST request essentially clicking on a button. For future reference, it'd be helpful to know how to send a POST request with, say, a username and password if I ever find myself in that situation in another hotel or airport.

• Restrict Administrators from changing system time - Windows XP machines (no domain)

  I need to write a script that will remove all users under Local Computer Policy > Computer Configuration > Windows Settings > Security Settings > User Rights Assignment > Change the system time from the local group policy (gpedit.msc) on all Windows XP machines. These machines are not on the domain. I DO have a way to distribute and run the script automatically. Can someone point me in the right direction for creating a script like this?

• dual-boot does not work

  - by elyashiv

  I have a PC with linux-mint installed on it. I wanted to install win-7 along-side, for some reasones. what I have done is: create a bootable USB-stick with Ubontu ios. restarted the computer, this time with Ubuntu (running from my disk-on-key). created a partition on the main HD using GPart. formated the partition to NTFS. restarted the computer, this time through the installation CD for win-7. installed win-7 with normal settings. that all worked, and I'm writing this through win-7. the thing is - when I boot my system, I don't get to choose what OS to run. I checked the settings in msconfig, and in boot label it has just win-7. how can I boot linux?

• Server IP must be a LAN IP (Port Forwarding Netgear)

  - by rphello101

  I'm trying to set up a server (Apache) on my computer (fairly new to it). As I understand it, for it to be accessible to other computers, I need to forward port 80. When I try to forward the port though, I get the error: Server IP must be a LAN IP. I noticed in ipconfig that my default gateway is different than my wireless router. My computer is not hardwired, not on WiFi. Furthermore, I do not, at this point, have a static IP. I read that it should still work with a dynamic IP until it changes. Any ideas on what I can do?

• Windows 8.1 will not go back to sleep after waking up

  I have problems putting Windows to sleep and starting the screen saver on my new Windows 8.1 machine. Sleep mode and screen savers work only when the computer is first powered up (or restarted). But once it goes to sleep (manually or automatically) and I wake it up later, it wont go back to sleep again and I can't use screen savers either. I updated the chipset and graphics card drivers. My computer isn't part of a homegroup either. Does anyone else have similar issues? Thanks for your advice, per
