I'm honored and pleased to be the person who gets to complete
ls. This
project, begun around when I was born, was slow to turn into anything more
than a simple
for loop over a dirent. It really took off in the mid and
late 80's, when Richard Stallman added numerous features, and the growth
has been steady ever since. But, a glance at the man page shows that
ls has never quite been complete. It fell to me to finish the job, and
I have produced several handy patches to this end:
The only obvious lack now is a -z option, which should make output
filenames be NULL terminated for consuption by other programs.
I think this would be easy to write, but I've been extermely busy IRL
(moving lots of furniture) and didn't get to it. Any takers to write it?
Due to the nature of these patches, they conflict with each other.
Here's a combined patch suitable to be applied and tested.

It remains to be seen if multi-option enabled coreutils will be accepted
into Debian in time for the next release. Due to some disagreements with
the coreutils maintainer, the matter has been
referred to the Technical
Committee
(
Flattr me)
Traditionally new
ls contributors stop once enough options have been
added that they can spell their name, in the best traditions of yellow
snow. Once
ls -richard -stallman worked, I'm sure RMS moved on other
other more pressing concerns. The current maintainer, David MacKenzie, was
clearly not done yet, since only
ls -david -mack worked. But he was being
slow to add these last few features, and
ls was very deficient in the realm
of spelling my name (
ls -o -hss .. srsly?), so I took matter into my own
hands in the best tradition of free software.
Many of the SAN components in Debian have me involved. So I think out to give an update on what the state of SAN would be in Debian Wheezy. Open-iSCSI: Just uploaded a newer version to experimental which eventually will crawl into testing. It should fix all release goals for Wheezy. Please give it a good testiscsitarget: Same goes here. This one is already in testing. Please test. It has some bugs reported, all in needinfo, as they haven't been easily reproducible or reported complete.multipath-tools: It is in pretty good shape. Some minor bugs. But still, please test. :-)Open-FCoE: Being dependent on hardware, for which I couldn't manage resource commitment, this one is literally untested. It lies in testing, untested.LIO Target: The newest target implementation for Linux. It is also available in testing, has had some minor bugs reported by users, and fixed. If you use, or anticipate to use it in the Wheezy life cycle, now is the time to test.
A while back, I was thinking. Playing the flute or whistling on a
bottle is the exact same technique; but, in my opinion, the sound that
comes from a bottle has some interesting overtones, making for a nice
sound. Since the material of which an instrument is made is in large
part responsible for the overtones that it produces (apart from the
technique used by the musician), I wondered if nobody had ever come up
with the idea of making a flute in glass.
Turns out that, of course, this has already happened. In fact, the
modern concert flute wouldn't have been possible without one Claude
Laurent, a Parisian instrument maker who received a patent for "a new
[method of] making flutes from crystal"; part of his patent described a
method of attaching the valves to the instrument. It was this method
which was used by Theobald Boehm when he invented the fingering system
that defines the modern concert flute.
The price of an intact Laurent flute today is, of course, beyond my
budget; and it doesn't look like there are any glass flutes being made
that use the Boehm system. But that doesn't mean there aren't
any glass flutes being made anymore; indeed, a short look
around the Internet quickly turned up 
.
