I had suspended to ram and restored => clicking.
Fresh boot today => no clicking.
Also the intervals are 0.1, 0.3, 0.6, 1.0, 1.5 seconds.
And, yep, I've ordered another hard drive.

I got a new hard disk.
I still get the same clicking, but now it also sometimes happens before
I type in the passphrase to unlock the luks encrypted lvm partition the
OS sits on.
Maybe it's the hard disk controller.
I also took out the Broadcom wifi/bluetooth pci express card as it was
acting up too.
Maybe it's time to retire this Samsung NP-RF711-S07UK.
Bought in 2012, that's four years more than the warranty.

Still using the Samsung, no clicks at the moment.

Talking SPI using the sd card slot
Hi there. This is about talking SPI with 1/2/4/8 simultaneous data streams at 25MHz/50MHz from a desktop/laptop amd/intel pc with a built in or external sd card reader at 3.3v. I originally posted this question here: http://stackoverflow.com/questions/25507249/how-do-i-control-an-sd-card-reader-using-spidev lsusb reports my device as a Alcor Micro Corp. Multi Flash Reader but that device is only present when I have an sd card in the slot, so something's adding it and removing it. It's that something that I want to replace with spidev (somehow). I've built a custom kernel to enable the experimental spidev module but I've no clue about how to proceed. Any takers?

One of them is a 250 GB drive (debian) and the other is a 300 GB (data). I've decided to give one of them to my parents because the one they have right now makes some strange noises. So I've backed up and cleaned up the drive, and as we speak I am cloning my debian install (from the 250 GB disk) onto the other drive. Sounds to me like a job for dd, or more specifically, ddrescue. ddrescue is featured on the System Rescue CD (http://www.sysresccd.org/SystemRescueCd_Homepage). With ddrescue's logs and many ways of writing, you can be assured of the maximum possible likelihood of getting the job done, and finding out if either drive has problems that should concern you. If you want a quick way of cloning the drive that isn't particularly error prone, this is it, especially if your 250 is fairly full so that file by file copy wouldn't save you much. If both drives are in good shape so there are no misreads or miswrites, I'd imagine the clone will take about an hour, unattended. If there are disk problems it will take longer, but file by file might have missed that fact and written bad data. My fstab contains blkids to identify the root, swap, and home partitions. Will the new clone just boot as if it was on the old drive? After cloning the 250 onto the 300, the 300 will boot just like the 250, always assuming your last step before doing the clone is to get rid of the 300's entry in fstab. Labels and blkids on the 300 will be identical to the 250's after cloning. Also is there a simple method to resize the future home partition and move the root partition so that I don't end up with unallocated space on the drive? Now you're getting a little complicated. What I always do in this situation is just make an additional partition to consume that last bit of drive space, and usually find a use as a scratchpad area for that partition. Or, if you really want to make /home bigger, you can take the biggest subdirectory in /home significantly smaller than the new partition, rsync its contents to the new partition after mounting it, back them up somewhere else, remove them leaving only the empty directory on the original, and mount the new partition as that directory. If you want to expand a partition to include the unallocated space, I think you have to use whatever partition butts up against the unallocated space to make bigger. If there's a tool to enlarge a different partition and move the others to compensate, Im not aware of it. gparted can do this.

Re: Shutdown computer after a specific command has been executed

Hi,
I need a tool that would make sure that, my computer would shutdown
after a specific command has been executed. This tool would just wait
for the Terminal for executing a command, like '/sudo apt-get upgrade/'
and then after the command has been executed, my computer would
shutdown. Is that possible? Is there a tool or anything out there that
can do this for me? Let me know. It would be of great help. Thanks in
advance.
Muntasim-Ul-Haque
to shut down the computer from a script or command line use
shutdown -h now
It needs elevated(root) permissions so initially I was tempted to use
sudo shutdown -h now
but I think sudo has a timeout after which it prompts you to re-enter
your password, probably not what you want.
So the solution would be to sudo everything and drop to a regular user
to run your command, unless it too needs to be run as root.
My bash scripting isn't sharp enough to do it but here's a place to
start from for user bob, uid=1001
sudo { su -l bob -c 'echo $UID' }; echo $UID
Yes it doesn't work, but if you can tweak it to output 1001 and 0
then you've solved it.
Maybe it's easier to create a script file that takes your command then
shuts down.
There are also other ways to do this that depend on which desktop
environment you're using.

I want to reuse this disk space, with lvm, and migrate existing wheezy installation to it, occupying the whole disk this time and bringing back most of the old data saved in the tarball. Any comments on best way and steps to accomplish this? Thanks. I boot Windows + Ubuntu + Wheezy, using an encrypted LVM for Ubuntu, shared partitions, swap and Wheezy. Currently the only way I can do this is to install using VMware Player to a .vmdk and configure for encrypted LVM. Then I mount the .vmdk and copy the image over and rename some stuff using a script, so if I make a mess I can change the script and restart fromthe reference image. I still have tomanagegrub.cfg by hand as Ubuntu and Debian try to overwrite it when a new kernel comes along. Also, you need a separate /boot partition, outside of LVM.

Synaptic can't find Debian changelogs
Hi there. When I click on the Get Changelog button for a package, for example llvm-3.2, I get This change is not coming from a source that supports changelogs. Failed to fetch the changelog for llvm-3.2 URI was: http://packages.debian.org/changelogs/pool/main/l/llvm-toolchain-3.2/llvm-toolchain-3.2_3.2repack-2/changelog so my first question is, doesn't packages.debian.org support changelogs or is Synaptic getting it wrong?

It's not the way I like to do things, but I just don't have time to solve this mess. Have you run `update-initramfs -u`? I did. I also adapted grub.cfg to point it to the correct partition and ran update-grub. Still, at boot the system keeps asking for a partition with the original name. A grep on /etc and /boot does not find it anymore, but the systems keeps asking for it. Grx HdV I had a similar problem with Where does the update-initramfs hook get the kernel name from? http://lists.debian.org/debian-devel/2011/01/msg00796.html I just realised that I posted the solution - to myself. Here it is. According to the docs you mentioned, the script gets supplied the kernel version from uname -r. The output I get is 2.6.32-5-amd64, not 26.32.5-amd64.squeeze as you see above, so the documentation must be wrong. Philip I finally went ahead and did an apt-get source initramfs-tools to check this out after upgrading to Wheezy. The postinstall hook was calling update-initramfs -u This script looks in $STATEDIR which is /var/lib/initramfs-tools by default, for versions to sort so it can get the latest one. The problem was that if you create a few flavours yourself, delete them in /boot and don't know about $STATEDIR then update-initramfs -u will forever more tell you about non-existent versions. The solution in this case is to delete the checksum files in $STATEDIR that match the ones you already deleted in /boot. The correct procedure is to update-initramfs -k some-version -d. There should probably be a Debian web page to store solutions to problems like this. Regards, Philip -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe.

Can DVD isos be converted to use h264?
Hi there.
I'm one of those people who think that the DVD menu is part of the movie
experience - otherwise I'd just convert the VOB files and be done with it.
Yeah, I know - the DVD standard mandates mpeg-1 or mpeg-2, but in a
recent test, xbmc 3:11.0-0.1 appeared to want to at least try to decode
the DVD iso I converted:
You'll need to install xbmc-skin-confluence - xmbc will bail without it.
Here's a snippet from ~/.xbmc/temp/xbmc.log
CDVDVideoCodecFFmpeg::Open() Using codec: H.264 / AVC / MPEG-4 AVC /
MPEG-4 part 10
So it looks promising.
I'm either encoding those VOB files incorrectly and/or not generating
the ISO correctly.
I've attached a script that uses fuseiso9660 to user-mount a dvd iso
onto a directory, converts the VOB files to h264 and runs genisoimage to
create a new iso.
The new iso is 1,861,853,184 bytes long compared to 7,249,934,336 bytes
- quite some space saving if I'm doing it right.
I've attached a script based on what information I could find - but is
this approach correct?
Any comments/suggestions welcome.
Regards,
Philip Ashmore

It's just advice to someone who seems to think that owning copyrights makes the publishers his masters. Fair enough. There is a great deal of software, and certainly other cultural material (books, movies, music) out there which has no FLOSS equivalent, and I don't have the time / skill to manufacture my own. Do as you will. The point is, you don't actually _need_ that stuff. Quite true. You peruse it by choice (and so do I (except for the movies)). Agreed. Is it really reasonable to refuse to read all books that have not been released under a FLOSS license? It is evidently feasible to not read at all. I'm sure you have neighbors and/or coworkers who are living example of that. True. Celejar Ho hum. I just have to wade in with one additional point. Back in the day I remember when CD-ROMs were being promoted/released. I think it was on Blue Peter. They demonstrated how robust a medium it was by spreading marmalade (it's like jam) on the thing, wiping it off and showing that it still worked. These days I don't dare look sideways at a CDs or DVDs in case they catch a scratch. I'm backing up my collection onto hard disk and I'm using a CD/DVD repair kit, and I have to use it once or twice on those items I watch more frequently, oh gee, I must have watched that one a lot, out with the repair kit. This is all going to change once augmented reality really kicks in - last time I checked you could still invite friends over to watch a movie or listen to music. Once your place becomes virtual, no copyright laws are being broken, or am I wrong here?

slow DVD reading
Hi there. Ever since I heard about the Raspberry Pi, I dreamt of putting my entire DVD collection on a usb disk and having a DVD juke box that would fit into a DVD case. While I'm waiting for my Pi to arrive, I started copying DVDs onto ISOs - what can I say, I love those DVD menus. Unfortunately they take ages to copy. I'm using Brasero on kde-trinity and it never works out the estimated drive speed, but from the progress indications (3206MiB of 5726MiB) it looks like it's managing 3-4MiB per second. It's a Samsung RF711-S07UK laptop with a blu-ray drive, so I was expecting it to be able to read a lot faster. What, if anything, can I do to make it read faster?

Faking quad buffers using VirtualGL for use with a 3D TV
Hi there. If you or someone you know has a 3D TV I bet you've wondered what it is about an OpenGL graphics card that's different from a normal or 2D graphics card. The short answer is - there is no significant difference, and some 3D laptops use the same graphics chip that 2D ones do - see http://www.zdnet.com/blog/computers/ces-2011-sony-debuts-vaio-f-series-3d-laptop-with-new-nvidia-geforce-gt-540m-graphics/4690 Some higher-end machines may use 2 2D graphics chips/cards, one for each eye. When you look at the actual 3D hdmi output format, it turns out it just outputs the two images one above the other - see http://hdguru.com/3d-hdtv-and-hdmi-explained/1336/ YouTube allows users to post 3D videos which you can search for with yt3d:enable=true. When YouTube detects this tag it adds a 3D button that allows you to choose several ways to view the video. Here are some examples: YouTube in 3D: http://www.youtube.com/watch?v=5ANcspdYh_Ufeature=plcp StereoQuake: http://www.youtube.com/watch?v=tXvirxRK-Ww I thought this would be something that's possible - even straightforward - to do with VirtualGL, but as you can see from this discussion Faking quad buffers for 3D TV http://sourceforge.net/projects/virtualgl/forums/forum/401860/topic/5335139 the author of VirtualGL seems somewhat inflexible in their approach, either that or they're missing the point I repeatedly tried to make. Maybe if Debian users show that they understand the concept, Debian can make a patch that someday might be accepted upstream. I just want to give Quake3 a go with a 3D TV - where's the harm?
