BlockSize Length in Vorbis Encoder
Hi,
How does vorbis encoder decide upon the variable block/frame size length?

Association broken when upgrading from rails 1.2.6 to 2.2.2
I have an app with the following models:
course
belongs_to :semester
semester
has_many: courses
belongs_to :education
education
has_many :semesters
In my old app (rails 1.2.6) I was able to access variables via
controller
@courses = Course.find(:all)
view file:
<% for course in @courses %>
<%= course.name %> <- this line works
<%= course.semester.name %> <- this is now

ext3fs: Bad super block
I've got this poor ext3-partition which I can't access. I have tried a lot
of things but it doesn't seem to solve the problem. I've got quite important
files on that particular partition.
I can't even get the block groups from my /dev/hda3 with dumpe2fs!
It all happened after a crash. GRUB wouldn't give me the graphical UI. I
decided I had to get my dosbootdisk and do an

block size
Hi,
we are implementing FLAC decode on an embedded device.
FLAC, as you know, can have block sizes up to ~65K.
For an embedded implementation, memory is limited: what would be the maximum block size we should support?
We have seen the encoder encodes either 1152 or 4608 in its default setup. Should we support other block sizes?
Also another unrelated question:

are 588 sample frames subset or nonsubset?
Hi
I am thinking of ripping albums to a single flac file with embedded
cuesheet. As track and index points have to be on a 588 sample boundary due
to the CD TOC standard working in 588 sample frames, I thought it may be
beneficial to rip CDs with a blocksize of 588 samples.
According to the format page on sourcefourge a stream is subset if

Questions about window sizes
Hello,
I have a few questions about the block size in ogg vorbis
1. The allowed blocksizes are powers of two between 64 and 8192 Samples.
As I understood , there are fixed sizes for long and short blocks .
The encoder can pick any allowed value for long blocks and onother value, that must
be smaller or equal to the first one, for short blocks.
On which base does the encoder choose the size for

Question on 4k sectors
Hi. Is the problem with ZFS supporting 4k sectors or is the problem mixing
512 byte and 4k sector disks in one pool, or something else? I have seen
alot of discussion on the 4k issue but I haven''t understood what the actual
problem ZFS has with 4k sectors is. It''s getting harder and harder to find
large disks with 512 byte sectors so what should we do? TIA...

package:AlgDesign and .Random.seed
Dear r-helpers,
Could you please help me solve the following problem: When I run
require(AlgDesign)
trt <- LETTERS[1:5]
blk <- 10
trtblk <- 3
BIB <- optBlock(~., withinData = trt, blocksizes = rep(trtblk, blk))
In response to the last command, R complains:
Error in optBlock(~., withinData = trt, blocksizes = rep(trtblk, blk)) :

ext3 4TB fs limit on amd64 (FAQ?)
Hi,
I've a question about the max. ext3 FS size. The ext3 FAQ explains that
the limit is 4TB.
http://batleth.sapienti-sat.org/projects/FAQs/ext3-faq.html
| Ext3 can support files up to 1TB. With a 2.4 kernel the filesystem size
is | limited by the maximal block device size, which is 2TB. In 2.6 the
maximum | (32-bit CPU) limit is of block devices is 16TB, but ext3
supports only up | to 4TB.

mounting filesystems with blocks larger then 4k over a loop device
So I'm playing around with S3 and elasticdrive, and I create a
filesystem on it with a block size larger then 4k.
mkfs.xfs -b size=8k /mnt/ed5/ed0 -f
This completes fine and sets up the proper filesystem. When I try to
mount it, however, I get:
mount /mnt/ed5/ed0 /mnt/eds35/ -o loop
mount: Function not implemented
looking at dmesg I get:

debugging question.
Hi,
I am using libvorbis-1.0.1 and I am trying to debug the example decoder
(examples/decoder_example.c) using gdb. I have compiled the source tree
for debug and can single step through the program.
However i am facing the following problem (which I think is more of C
than vorbis)

Samples inside a packet
Hi,
Just to confirm:
for blockSizes of 256 and 2048 (0 and 1 respectively) the number of sample inside this audio packet will be acording to table below:
LastWind ThisWin Samples
0 0 128
0 1 576
1 0 576
1 1 1024
Correct??
thanks a lot.

Encoding multiple tiny audio files
Hi all,
I want to make a static database containing hundreds of thousands of very
short audio files, each having not more than 100 milliseconds. These are made
by splitting larger audio files into tiny pieces.
I encode all the little files separately, but do not store 3 vorbis header
packets, which are the same for all the files. I do not use ogg stream, only
store plain vorbis packets.

ChaCha20 Rekey Frequency
I was wondering if there was something specific to the internal chacha20
cipher as opposed to OpenSSL implementation.
I can't just change the block size because it breaks compatibility. I
can do something like as a hack (though it would probably be better to
do it with the compat function):
if (strstr(enc->name, "chacha"))
*max_blocks = (u_int64_t)1 << (16*2);

free() invalid pointer
Hi,
Apparently the new presets are triggering an invalid free in
some code. I was running the test suite on ARM, and it gets
stuck with small blocksizes.

Parts of the standard not supported in reference decoder?
I am working on creating a set of FLAC files for a ?decoder compliance test corpus? and am looking for examples of things that are part of the standard but not supported in the reference decoder. I am not looking for things missing from the reference encoder (such as variable block sizes).
I seem to recall someone on this list (most likely lvqcl or Martijn van Beurden) mentioning something about

Two new CVEs against FLAC

I think I might have a fix, but it touches quite a bit of code,
so it'll take some time.
I think the problem is that because bogus headers might pop up
in the stream of which the CRC checks out, the whole frame is
decoded to validate that a frame is correct. The bogus header
