RSYNC via pipe/socket ?
Hello !
I`m trying to find a way to use lzo compression for the data being transferred by rsync.
rsync only supports gzip (or maybe ssh -c, which is also zlib), which gives cpu intensive workload - and
this cannot be exchanged by a commandline param like we have with tar (--use-compress-program=....)
i like to use lzo because it does much faster compression than gzip.
I read the following in

feature request: lzma compresion (7zip)
Hello,
many linux SW is starting to implement new lzma compresson instrad of old zlib (gzip) od bzip2.
lzma is default comrpession in very good compression SW 7-zip, which is faster and have higher compression ratio then bzip2 or rar.
Currently its probalby the best compressor in therms of compression and decompression speed / compression ratio.
In linux there is GNU lzma SW which implements

ZFS Compression algorithms - Project Proposal
Bellow, follows a proposal for a new opensolaris project. Of course,
this is open to change since I just wrote down some ideas I had months
ago, while researching the topic as a graduate student in Computer
Science, and since I''m not an opensolaris/ZFS expert at all. I would
really appreciate any suggestion or comments.

bzip2 compression bug
Hi,
I compressed many files using bzip2, but in some cases it crashes. I
believe that it is related to dovecot indexes.
How to reproduce:
Inside a Maildir folder without any indexes yet, compress a message with
bzip2 and tryes to access it.
At my server is showed the error:

benchmarking rsync's -z compression utility
Hi,
Is there a way in which rsync's -z compression (zlib) utility can be
benchmarked?
I'm trying to compare the compression ratio between rsync and external
compression tools like gzip and bzip2.
Are there any advantages to using rsync's internal compression mechanism
specified with the -z option compared to solely applying external
compression i.e. bzip2 to the files and invoking

[LLVMdev] Compression Stabilization
In preparation for Release 1.4, I've consolidated the bytecode
compression to only use bzip2. zlib is not supported any more. We chose
bzip2 because it offers about 10% better compression on bytecode files.
Its unlikely, but this change *could* affect you if you ever built the
CFE or your own LLVM project on a machine that had zlib but didn't have
bzip2. If you have bzip2 on your

LZO compression?
Hi,
I don''t know if this has been discussed before, but have you thought
about adding LZO compression to ZFS?
One zfs-fuse user has provided a patch which implements LZO compression,
and he claims better compression ratios *and* better speed than lzjb.
The miniLZO library is licensed under the GPL, but the author
specifically says that other licenses are available by request.

compression of source and target files
Hi - there's a flag for rsync to compress the files in transit - is it
possible
to compress one side (target) with gzip and have rsync still work
correctly?
Any help would be appreciated.

[PATCH v2] daemon: collect list of called external commands
guestfsd calls many different tools. Keeping track of all of them is
error prone. This patch introduces a new helper macro to put the command
string into its own ELF section:
GUESTFSD_EXT_CMD(C_variable, command_name);
This syntax makes it still possible to grep for used command names.
The actual usage of the collected list could be like this:
objcopy -j .guestfsd_ext_cmds -O binary

Request to speed up save()
In addition to the major points that others made: if you care about speed, don't use compression. With today's fast disks it's an order of magnitude slower to use compression:

> system.time(saveRDS(d, file="test.rds.gz"))

xz compression support
Hello,
Just wondering: Dovecot has gzip/bzip2 compression/decompression support.
According to this:
http://stephane.lesimple.fr/wiki/blog/lzop_vs_compress_vs_gzip_vs_bzip2_vs_lzma_vs_lzma2-xz_benchmark_reloaded
gzip and bzip2 aren't really useful together.
While gzip can offer speed and a reasonable amount of compression ratio,
bzip2 is slow, especially on decompression, which Dovecot does

compression method for qcow2?
I found guestfs_compress_out do the compression to gzip, bzip2,
compress...etc.
I want to compress qcow2, and I found details about qcow2 compression in
https://people.gnome.org/~markmc/qcow-image-format.html
The QCOW format supports compression by allowing each cluster to be
> independently compressed with zlib.
Can I do that with guestfs_compress_out?

Win95, sharing printers and drives
I have two computers ROLAND (RedHat 5.2 and Samba) and LINDA
(Windows95).
I am already able to print on the printer connacted to LINDA. Yesterday,
before I managed to get the printer working, I was alos able to see
ROLAND's directory 'tmp' and 'winD' on LINDA.
The problem that I saw this morning was that the printing still works

Migration Samba3 -> Samba4: Accessing domain member server is not working
Hi ...
When trying to migrate from samba3 to samba 4.2.2 I am facing a severe
problem that bugs me for hours now. I cannot get a samba 4.2.2
fileserver to work with a samba 4.2.2 PDC as a domain member.
My scenario:
Samba 3 network. PDC and fileserver where Samba 3.6.25. LDAP backend.
We can't move to AD right now so I wanted to move to the current 4.2.2

[LLVMdev] Compressing with llvm-ar
It's too bad that the compression feature was dropped. Can you share why?
I was interested in using llvm-ar to compress LLVM outputs. My experiments show that BC and PCH files are highly compressible (~35% of original size). I can see many situations that would benefit from a reduced storage size. I have tried other methods for reducing the file size such as tweaking with opt options (see

[PATCH 2/2] daemon: Replace GUESTFSD_EXT_CMD with --print-external-commands.
GUESTFSD_EXT_CMD is used by OpenSUSE to track which external commands
are run by the daemon and package those commands into the appliance.
However because this uses linker trickery it won't work from OCaml
code.
Replace it with a [nearly] standard C mechanism. Files still have to
declare the external commands they will use, eg:
DECLARE_EXTERNAL_COMMANDS ("btrfs",
