You're going to have to go into detail. Last I checked, old versions of Windows shipped with AVI files for their animations, and those AVI files played fine. So it _sounds_ like they're able to play video, at least. And my largish collection of AMVs and videos I've put together myself suggest that AVI can play synchronized audio and video. > Getting that wrong is to me akin to building a car and forgetting to > provide it with an adequate means of stopping.

Only if you anticipate your audio and video streams deviating from intended usages. AVI is used for far more things than it was designed to do. Reading deeper into its history, it sounds like it was embraced and extended by entities outside of Microsoft to do things it wasn't designed for in the first place. So expecting it to handle VBR audio or video with predictive frames is kinda like putting a supercharger in a Pinto and complaining when it winds up sitting on its own roof. > > > > >> 3) Integrated cleanly with their being-developed operating system (AVI >> is very closely related to the Video for Windows API.

Would you not agree that this is the second-most important feature required, where the ability to actually play the audio/video at all is the first? Getting that wrong is to me akin to building a car and forgetting to provide it with an adequate means of stopping.

The MPEG group had only been formed four years prior to AVI's release, and didn't release their first standard until a year later. Meanwhile, Microsoft needed a video file format that: 1) Was a file format that sat on disk 2) Synchronized audio and video 3) Integrated cleanly with their being-developed operating system (AVI is very closely related to the Video for Windows API. It's worth noting that WMF, another Microsoft format from this time, is essentially a serialized form of their drawing primitives.) 4) Ran smoothly on an 80386 at 33MHz with a 16-bit, 8MHz data bus between the CPU and persistent storage.

I won't disagree that AVI is a crappy format by today's standards, and that it should be avoided where possible, but what you consider simple and obvious today was *new* at the time, and so not simple and obvious. > It would have been obvious to the .avi developers then.

My first guess is that something on the same USB bus might be periodically active, changing how the kernel manages talking to USB devices. Try ensuring no other USB devices are connected (or active), and running something like "hdparm -t /dev/sdc; hdparm -t /dev/sdc; hdparm -t /dev/sdc; hdparm -t /dev/sdc; hdparm -t /dev/sdc; hdparm -t /dev/sdc" ...letting the shell automate it for you. My second guess would be something relating to the kernel's page cache...but I'm unsure if a filesystem needs to be mounted first. My third guess would be some internal buffering behavior inside the USB disk, and hdparm's behavior happens to straddle an edge condition. -- :wq

[gentoo-user] [OT] Curious hdparm results
I have a usb3 docking station which is showing some behavior I don't understand: #hdparm -t /dev/sdc /dev/sdc: Timing buffered disk reads: 266 MB in 3.00 seconds = 88.59 MB/sec Timing buffered disk reads: 268 MB in 3.01 seconds = 89.05 MB/sec Timing buffered disk reads: 266 MB in 3.01 seconds = 88.43 MB/sec Timing buffered disk reads: 266 MB in 3.02 seconds = 88.10 MB/sec Timing buffered disk reads: 306 MB in 3.01 seconds = 101.72 MB/sec Timing buffered disk reads: 266 MB in 3.00 seconds = 88.59 MB/sec Timing buffered disk reads: 306 MB in 3.00 seconds = 101.84 MB/sec Timing buffered disk reads: 306 MB in 3.00 seconds = 101.86 MB/sec That's all the same disk, repeating hdparm as fast as I could. The disk was not even mounted at the time, and no other disks were active. Two very different but reproducible numbers, changing values at random times. The only thing I can think of is that the disk may be doing a SMART self-test, but for some reason the USB connection prevents me from accessing the data so I can't test my theory. Any other ideas?

The record is about 420 days, and it will last for a while. So rebooting every few weeks is okay :) But it's cool that I _could_ do this without a reboot. Wonko

Hi, I had to mask icu-49 because some packages failed to compile during a world update. I reverted back to 4.8, but now certain applications complain about .49 missing. revdep-rebuild isn't able to detect breakages and neither revdep-rebuild -L libicui18n.so.49 solved the problem.

I saw that, but here it will be much easier. All is on LVM here, so this should
do it:
# enlarge root partition
lvresize -L +17G /dev/weird/root
cryptsetup resize root
resize2fs /dev/mapper/root
# make sure /usr is not being written to. For other partitions, I'd
# create an LVM snapshot
mount -o remount,ro /usr
# mount root to another place, without mounts like /usr showing up there
mkdir /tmp/bindroot
mount -o bind / /tmp/bindroot
# copy data over
rsync -ax /usr /tmp/bindroot/
# remove /usr stuff from fstab and dmcrypt
sed "/\/dev\/weird\/usr/ d" /etc/fstab
sed -i "/^target=usr2$/{N;N:N:d}" /etc/conf.d/dmcrypt
# done!
reboot
No need for downtime except for the reboot, I guess I cannot unmount /usr
otherwise.

I tried that first but it didn't work. When I started trying to use dracut, I didn't even think to disable or remove the in kernel one. I have updated my kernel several times since and I have not had a single issue. So, if you decide to use dracut, make sure you clean out the old cruft first. That said, I didn't know dracut could do the file system checks before mounting and doing the switch_root thing. I see it include the programs but never seen it actually do the check.

Which I do, every partition (including /) is on LVM, and except for /usr, /usr/src and portage stuff, all is encrypted. But maybe it's time to drop some partitions, and maybe include at least /usr and /tmp in the root partition. /usr would be encrypted again then, but the overhead seems to be small, so why not. Wonko
