• Windows 7 screensaver intermittently fails to turn on

  - by Zian Choy

  Context: Windows 7 Wired mouse and keyboard The Windows 7 Photos screensaver intermittently fails to kick in after 2 minutes. The computer knows that the time has passed because it will make my monitors display solid black screens. I already tried installing the latest mouse drivers from Microsoft and the problem persists. I also can't find any rhyme or reason to when the problem will happen. The problem happens even when Windows Media Player isn't running.

• Burn 30GB zip file to DVD

  - by Joel Coehoorn

  I have a zip 30GB zip file containing an archive a digital materials available in the school library that I want to burn to dvd. Of course, 30Gb is far too large for a single dvd and the content is already zipped. I'm open to ideas, but leaning towards suggestions that will help me automatically spread the file over multiple dvds, including a simple program to stitch it back together again later.

• How can I determine the sector size on an external hard drive?

  - by sigint

  Hard drives are transitioning from 512 byte to 4096 byte sector sizes, and it looks like Windows XP won't support these newer drives without additional software (such as WDalign from Western Digital) My question is: how does this affect external hard drives? I'll be buying a 1TB USB external drive, and it'll be plugged into a mix of Windows 7 and XP machines. Is there an easy way to tell what the sector size on an external hard drive is?

• How to record screencast on Linux with mouse clicks and key hits shown

  - by zalun

  Basically I'm looking for an application to record a series of tutorials for a program I wrote. It's important to show the actions like mouse click, mouse right click, and all what's coming out from the keyboard. In the similar way to this video http://www.flickr.com/photos/jannis/3246408003/ which is made using OSX and ScreenFlick www.araelium.com/screenflick/ Is there such an option? Thanks

• How can I set a minimum thumbnail size with ImageMagick?

  - by Zilk

  I'm trying to create thumbnails of JPG photos using ImageMagick's convert tool. The thumbnails need to have a defined size (210x159), no blank areas, and the image can be cropped if necessary. Unfortunately, I only have ImageMagick 6.3.7 available, which doesn't support the '^' geometry modifier (added in v6.3.8-3). Is there another way to achieve this in earlier versions of ImageMagick? Thanks in advance.

• External HD makes scraping sound when idle. How to disable it?

  - by StackedCrooked

  My external hard disk often starts making an irritating scraping sound. It stops if I do something that causes disk activity on it. But then, after 3 minutes or so, it starts again. It's very annoying. Is there a way to disable it? It's a Western Digital WD 10EAVS.

• Technically, How does uploading Apps to an Android Phone Work?

  - by unixman83

  Amazon.com has an Android Marketplace. How do the apps go from Amazon.com to my phone? I am looking for a protocol level analysis. Do they use a basic protocol like FTP and then check with a Google digital signature? I do not own an Android. I wish for an explanation of how the protocol operates because I want to provide an android app for free download for my users off my website, like Amazon does.

• Is my external hard drive dying?

  - by thatotherguy

  I keep getting this error lately when I try to copy large (200+ MB) files over to my external. Following this, the disk becomes unresponsive and I got to unplug it and plug it in again to work. The copy process also is unreasonably slow. It is worth noting that this happens on Windows too, so it's not the notorious "Error -36" bug OS X had prior to 10.6.3. The disk is a Western Digital 3200BMV. Any ideas?

• Convert file from VOC to MP3

  - by Thomas

  I would like to convert a sound file (from a digital voice recorder) with the extension .voc to an .mp3 file or some other common sound files. I am on Windows 7 64 bit. I have tried the program voc2wav but it gives me an error message saying that the program isn't 64 bit. The program has to be free and able to run without installing. (The voice recorder did come with a program that I could install, but I would like to avoid that).

  I want to add a 1.5 - 2 TB hard drive to a Linux file and backup server we have in the office. Will it make a difference if I'm using 5400 RPM vs a 7200 RPM hard drive? I was thinking about getting a Western Digital Green Drive or Samsung Ecogreen or similar.

• Windows 7 explorer doesn't use details view in folders with media

  - by OliverS

  I use details as my default folder view, which works fine except for folders that only contain media files like photos or mp3. In these cases the view changes in order to show thumbnails etc. (which I also disabled). How can I prevent this view switch and tell the explorer to stick to details view.

• Architectural advice - web camera remote access

  - by Alan Hollis

  I'm looking for architectural advice. I have a client who I've built a website for which essentially allows users to view their web cameras remotely. The current flow of data is as follows: User opens page to view web camera image. Javascript script polls url on server ( appended with unique timestamp ) every 1000ms Ftp connection is enabled for the cameras ftp user. Web camera opens ftp connection to server. Web camera begins taking photos. Web camera sends photo to ftp server. On image url request: Server reads latest image on hard drive uploaded via ftp for camera. Server deleted any older images from the server. This is working okay at the moment for a small amount of users/cameras ( about 10 users and around the same amount of cameras), but we're starting to worrying about the scalability of this approach. My original plan was instead of having the files read from the server, the web server would open up an ftp connection to the web server and read the latest images directly from there meaning we should have been able to scale horizontally fairly easily. But ftp connection establishment times were too slow ( mainly due to the fact that PHP out of the ox is unable to persist ftp connections ) and so we abandoned this approach and went straight for reading from the hard drive. The firmware provider for the cameras state they're able to build a http client which instead of using ftp to upload the image could post the image to a web server. This seems plausible enough to me, but I'm looking for some architectural advice. My current thought is a simple Nginx/PHP/Redis stack. Web camera issues post requests of latest image to Nginx/PHP and the latest image for that camera is stored in Redis. The clients can then pull the latest image from Redis which should be extremely quick as the images will always be stored in memory. The data flow would then become: User opens page to view web camera image. Javascript script polls url on server ( appended with unique timestamp ) every 1000ms Camera is sent an http request to start posting images to a provided url Web camera begins taking photos. Web camera sends post requests to server as fast as it can On image url request: Server reads latest image from redis Server tells redis to delete later image My questions are: Are there any greater overheads of transferring images via HTTP instead of FTP? Is there a simple way to calculate how many potential cameras we could have streaming at once? Is there any way to prevent potentially DOS'ing our own servers due to web camera requests? Is Redis a good solution to this problem? Should I abandon PHP/Ngix combination and go for something else? Is this proposed solution actually any good? Will adding HTTPs to the mix cause posting the image to become too slow? Thanks in advance Alan

• Why do firewire drives on Mac OS cause processes to go into uninterruptible wait?

  - by akraut

  I have a Western Digital My Passport Studio external hard drive. It works with either Firewire 800 or USB 2.0. I've noticed that when I have it connected to Firewire, after a few hours, processes on my Mac start to go into an uninterruptible wait state. Eventually the system becomes so hard locked that I can't even shut it down. I have Spotlight indexing of the drive disabled, and the mds process seems to be the one that triggers this eventual system collapse.

• Why Windows Live Photo Gallery stopped displaying thumbnails, and how to fix it?

  - by Alex R

  I now get this instead, for most (but not all) photos. This is the icon which represents the WLPG application, I think. Some observations: I can see the thumbnails fine in Explorer, which is where a lot of other people have this problem. My C:\ drive may have temporarily filled up at some point recently, but then was cleaned up. Double-clicking on the photo will display it fine, so I know it's not file corruption or permissions issues. Thanks

  (I'm using windows-7 and the hard drives are western digital with whatever formatting they came with from the factory) i'm thinking of setting up two different back-ups one through windows and one with the software that came with the drive (because windows gives me a system image but isn't very user-friendly for my files) but will my computer get confused and load them as different letters each time?
