Of course there is, since that's the way the world works.  You don't
think so, because you're wrong.  You've managed to acquire a good
theoretical understanding of Bayer while completely missing the
crucial bit that you neither need nor want four adjacent photo sites
per output image pixel.  (A miracle of modern education.)  In real
cameras, each pixel gets color info that it's missing by interpolating
from its neighbors.

http://www.dpreview.com/learn/?/Glossary/Camera_System/Color_Filter_Array_01.htm

Before you try to argue this point again, find one camera that works
the way you suggest, or one website that explains that Bayer cameras
have 4 photo sites per output pixel.  Otherwise, don't confuse people
who haven't learned not to listen to you yet.


As an aside, the reason you don't want to have four adjacent Bayer'd
CCD cells per output pixel is that the decreased CCD size would
result in more noise, canceling out the benefit you would get from
slightly better color resolution.

The Foveon chips do have four photo sites per pixel, allowing true
color detection, but they're stacked, not adjacent.

 As a side note, what could be interesting is if you could disable or
 remove the color mask to get 4 times the resolution on B/W pictures.

Kodak used to offer one of their DSLRs with and without the color
filter.  The DCS760 was color, the DCS760M was B/W, lacking the
filter.  But both output the same 3032 x 2008 file (gee, looks awfully
close to the resolution of the CCD, doesn't it?) and the somewhat
increased luminance resolution in the b/w wasn't interesting enough
for photographers to buy enough.  Kodak doesn't offer them anymore.
(I'm pretty sure there are monochrome digital backs, but those are an
entirely different price range.)

 The real benefit to having the Windoze apps (Nikon or not) to support
 the camera is in being able to load camera (or film scanner) images
 directly into something like Photoshop without having to go through
 any JPEG or other compression, so that you can manipulate raw
 images.

Note, this only matters if you have set the camera to save things as
RAW format.  If the camera is saving JPEGs, the software can't
convert them back into RAW... info has already been lost.

Why does RAW matter?  It is uncompressed and has more bits than a
JPEG (12 bits on my D1x) so you have more range when doing exposure
adjustments and whatnot.

There's a program called dcraw which will convert many forms of
camera raw files into standard formats for editing.  But it's not
quite as good as the Nikon Capture software, because Capture makes it
very easy to do common things like fix exposure and has cool toys
like DEE which is basically a magic exposure fixer.  Nothing you
can't do without capture, but you have to work harder to get there.

Micha Feigin [EMAIL PROTECTED] writes:

 Some cameras actually compress the raw data BTW. I think Nikon does
 that since nef (raw) output takes less space then tiff output.

On some Nikon cameras they are compressed using a visually lossless
algorithm.  Some recent posts on the D1scussion group indicate that it
reduces the effective bit depth from 12 bits to 9.  Ick.  My camera
has a toggle to select compressed or uncompressed, but I don't
believe the lower-end ones do.  

But even the uncompressed ones can be smaller than TIFFs, since they
only log 12 bits per pixel, where the TIFFs are 8 bits per color per
pixel.  So uncompressed should be about half the size.  (This is
because each pixel is only R, G, or B straight from the CCD.)

 There is also a plugin that allows using draw to open the raw files
 directly in the gimp. That should rival the Nikon capture software.

In terms of quality (assuming a 16bit/color gimp), yes.  In terms of
ease, no, since Nikon Capture has a lot of prepackaged actions which
do exactly what a photographer wants to do, and the gimp doesn't.  Of
course, they could be added... 8^)

 Looks like you missed it a bit here. What you would call a pixel in the
 raw file is not the same as a pixel in the tiff file.

Actually, it's close enough.

 In the raw file you have 4 ccd cells per image pixel (R, G, G, B)

That's not correct for any Bayer camera I know of.  Specifically not
correct for the Nikon DSLRs or consumer cameras.

There's one CCD cell per image pixel, with the exception of the D1x,
which has a strange layout[1].

 corresponding to the Bayer mask, at 12 bits per cell, which should make
 that 48 bits per pixel, which in turn should make the file
 approximately twice the size of the standard tiff (I think NEF files
 are actually tiff files with some undocumented extensions IIRC).

Correct, NEF files use a TIFF container.

As for sizes, TIFFs from the camera really are about twice the size
of uncompressed RAW.[2]  If you really want, I can provide pics taken
in each mode.

 The compression option probably lets you chose between lossy and
 lossless compression and not uncompressed versus compressed, but its just
 a wild guess.

The D1x allows a choice between uncompressed and compressed[2].  The
D70 does not.[3]  Neither allow you to choose lossiness.  The above
link explains the loss of detail.

(You're guessing.  I've got the camera.)

 I will have to read the code or the specs for dcraw.c (hope I got the
 name right) to give you an exact answer to this.

See [3], where they did.  There's also more info in the D1scussion
archive[4] which is unfortunately available only to members.

 IIRC most relevant filters are already there or available, and I don't
 like the magic filters of 'simple user' software anyway since it
 usually doesn't do what I need (don't know Nikon Capture so I may be
 way off the mark here).

Yep, you're way off.

For example, NC offers:

* Autoremoval of sensor dust from images, given a reference.  

* Fisheye-to-rectilinear with some lenses.

* Vignette control, to increase or decrease vignetting.  It knows the
  properties of the lens you used.  Very cool.

* Lets you adjust exposure by standard EV values

* Easy highlight/shadow adjustments.  Really, really easy.[5]

Now, you _can_ do all of this with the gimp.  But it's a more manual
work.  NC lets you work on thumbnails, set image settings, then batch
convert.  And you're limited in your plugin choice because you have to
use filmgimp to get 16-bit color, to take full advantage of the extra
range in the files.  Or, use the RawPhoto plugin and fiddle with
settings before actually converting it into 8-bit per channel, but
then you're severely limited in your available modifications.[6]

 Here's some documentation. It's a little out dated and not specific to

Of course, that guide guarantees crappy output on any printer better

fonts, DDX driver configuration information, and other stuff you will
hopefully never have to look at (See also: Section 2 of Xprint Service

I don't see why that's Xprint's fault [1].

Because CUPS has all this information, and Xprint, living in its own
world where BSD lpd is the most advance printing system, requires
that everything tell it all the information you could possibly want
about the printer.

It's also Xprint's fault because it, unlike the naive output used
by everything else in the universe except WP8, resamples images, so
it will look worse without significant configuration.

 If it requires additional setup to get a perfect printout then a bug
 report should be filed so that the package maintainer can learn how to
 create a proper deb.

It's not a package maintainer problem.  It's an xprint problem.  Look
at http://bugzilla.mozdev.org/show_bug.cgi?id=5517 .

 [1] the problem might be that the printing system interface (lpq,

 DPI capability.

Or it might be that Xprint currently can't take advantage of this
information.

Using XPrint is the problem, not the solution.  It makes configuration

it really has the same functionality that it could (and probably does

As far as quality, XPrint assumed my printer was 600 DPI (or was it

 I am trying to detect that a file has stopped copying via FTP. As an
 example: User sending a file via FTP (100MB), cron job to test if the file
 has completed and then launch a command to do something with that file.

You could just keep checking the file size to see if it stops
increasing, but you probably don't want to run your process if the
FTP times out and the file is incomplete, and you don't want to
accidently trigger if it pauses too long.

I suggest the ftp file is ftp'd up with a temporary filename and then
renamed to the real file.  (FTP supports renames.)  Then, just watch
for the real filename.  Once it appears, you know that the transfer
has completed successfully.  (Conveniently, renames are
instantaneous, so you can't catch _that_ in the middle.)

 I am using dhcp3-client to pull the ip number and other assorted

It may not be sending one, since most clients don't care what their
hostname is.  Use a script to use the host command to pull the name
associated with the IP and put it in any config files which need it,
and restart any services which need to be restarted.  (Applications
generally don't care what the hostname is, so you won't be killing
user apps.)

This is really a fairly common setup.  As I mentioned, Windows and Mac
don't generally really care what the hostname associated with their IP
is.  Few applications care.  So DHCP servers just hand out IPs, and
most apps which need a hostname can do the reverse lookup.  Unix is
different in that it generally assumes a hardcoded hostname somewhere.

 Alan, I'm working on a rewrite now and am concerned with properly

You'll have to stop getting the email address from the form.  Sure,
it makes it easier.  Unfortunately, it makes it easier for spammers,
too.

A few ideas:

* Hardcode the destination address in the script

* Hardcode multiple addresses in the script, and have a token in the
  form specify which address to mail to.  For example, if the form
  says address=FOO, you look it up $addresses[FOO] to get
  [EMAIL PROTECTED].

* Just discontinue the script, and have people use formmail.  That
  way, the security burden is on someone else (admittedly, someone
  who's proven themselves incapable of fixing security problems).

Sure, all of these make it harder to use, but the only way to stop
spammers is to restrict the addresses they send to.

 What's the advantage here? Security through obscurity?

The reason formmail became so popular was that you could use one form
on the server from different pages sending to different people.
Specifying a token in the form which maps to an address in the script
allows this.  It's not security through obscurity, it's security.
Someone from the outside can only use the script to send emails to
the addresses that are specified in the script -- no others.

* Just discontinue the script, and have people use formmail.  That

 Heh, you think the situation's really that bad huh Alan?

Google for formmail security and look at the insane list of
problems, and the list of programs which have sprung up to try to fix
the problems.  Why add another to the list?

 BTW, how do server side ENV vars get spoofed? 

$ENV{HTTP_REFERER} is set by the HTTP server to be the value the
client specifies in the Referer: header.  The client is able to send
no value, or any arbitrary value.  So it's just like the user agent:
not to be trusted.

But you don't want to disable _all_ checks, because a journaling fs

 As much as I like Wine, and use it myself for some products, I fear that
 the wine project may do to linux what win-os/2 did for os/2.  If your
 system will run win32 apps, what insentive do companies have to develop
 native programs for you.

Well, Wine has been around for what, ten years now and this hasn't
happened?  And in a way, it's been at roughly the same functional
level for most of that time.  Many apps work to some extent, some work
very well, some don't work at all.  (The exact apps and support keeps
changing, because it's a moving target.)

I don't foresee Wine ever becoming so complete that many companies
will use it as an excuse not to write Linux versions.  A few have
tried, and have mostly failed in the market.  (Games I think are the
only area where it's been taken seriously.)  Unless Windows stops
moving, Wine isn't going to catch up.  And if Windows stops moving,
it can only be because we won.

Note that the WineHQ's myths page disagrees with me, but 10 years and
no v1.0?  History weighs against their arguments.

 How can an email virus work on *ix?

How does it work on Windows?  Either convince the user to click on a

the user's address book and mail archives, and send out lots of
email.  Include your own SMTP client to contact servers.  None of
this is restricted by root.

It can also pop up a DDOS or SPAM server running as the user in a
high-numbered port.  If it wants root-level privileges (which none of
the viruses out for Windows seem to need or care about) it can pop in
a sniffer or some sort for the user's keystrokes to see if the user
ever su's.

 And a click-thru virus (or is it really a trojan?) can only do 
 damage to files that you have privs to touch (unless there's a bug
 in Java or JavaScript).

Sure.  So?  All the files I really care about are the ones I have
privilege to touch.  I don't care about the OS so much... I can
install it again.  I do care about the documents or code I'm working
on.  Or my local customizations.  I have a 2GB home directory on my
laptop at the moment.  I care more about any of that data than
anything the virus can't touch.

Or, at work, I have access to modify all sorts of things that I need
to in the context of my job.  A virus could have a lot of fun.

Sure, you can mitigate the risk.  Backups, CVS repositories, secondary
accounts for certain things, keeping things on several machines, can
all reduce the damage a virus could do.  But just saying A virus
can't hurt a user unless it's root is incorrect.  And downplaying
that it can affect any file the user can touch ignores where most of
the value is in the files on an average system.

Since the font server can only deliver bitmaps to clients (even
though it can read outline fonts, it rasterizes them before sending
them over the wire) it isn't helpful to many programs.  Any program
which wants to antialias, use outlines, or send decent stuff to a
printer needs its own access to fonts.  Any program which wants more
metrics than the X font protocol provides needs its own access to
fonts.  So, if you have a new font, you may need to tell
OpenOffice.org about it, X about it, GS about it

This is gradually getting better now that we have fontconfig, which
hopefully gives all the info all apps needs, but to suggest that xfs

Alex Malinovich [EMAIL PROTECTED] writes:

 C is easily the dominant language for most things Linux. So therein
 lies the question. Why, exactly, is C so popular? Especially in
 comparison to C++. 

The free software culture started much before Linux.  Much free
software was written to run on many different Unix systems.
Historically, a C compiler was available on all of them.  Even after
vendors started dropping C compilers, they often included an old
KR-style C compiler which was enough to bootstrap GCC.  The C ABI was
very stable, and you didn't need to recompile everything all the time.
It wasn't too bad getting shared libraries to work on most platforms.

In contrast, C++ was not available on most Unices with the base
system.  When it was purchased as an upgrade, it turned out that
different vendors C++ compilers were often buggy and incompatible in
many ways.  Sure, you could require that everyone install GCC, but
that was plagued with its own set of problems.  In the end, you were
stuck using a much decreased subset of C++ for very little benefit.

Then C++ was plagued with a very long standardization process where
the language changed greatly and compiler vendors had to play catchup.
It's only just getting to the point where compilers fairly faithfully
implement the language, and are reasonably compatible, nine years
after I first saw C++.  And on linux, you still have binary
compatibility issues (look at how you have to use a different JVM
under Mozilla depending on what compiler it was compiled with).

As a consequence of this, very little free software was written with
C++.  It just wasn't worth the minimal gains you might get for the
headaches it caused.  Groff was the only app I can think of that
historically used C++, and ISTR it had problems along the line.

This is slowly changing, as we have Mozilla, OpenOffice.org, and KDE,
but you asked for the history

 a) public domain
 b) copyright released to the FSF

Yes.  But as I mentioned in my previous post, when you sign the FSF
copyright assignment form, they grant back to you a perpetual,
non-exclusive, irrevokable right to use the code you are assigning
them for any purpose you want.

My assignment is on file somewhere at home, but I suppose I could dig
it up and excerpt it for you.

 Not quite: it's true that they won't accept XEmacs code due to copyright
 issues, but I don't think it's a matter so much of XEmacs saying they
 won't do it, as that in the XEmacs code it's not clear who has copyright
 and tracking down all the people that _might_ have copyright and getting
 them to sign has proved too daunting for the ROI.

Exactly.  There have been a number of cases where things moved from
XEmacs to Emacs when it was feasible to get copyright assignments,
and I know a number of the main XEmacs maintainers have signed papers.
It's just not always feasible to do so.  And in some cases, even if
it would be feasible to do so, the implementation would be so much
different than the implementation in Emacs that it needs to be
rewritten anyway (ie, internal redisplay stuff).

 This makes a lot of sense. I mean if the FSF hired you to write a
 GPL program, they wouldn't want you to release a proprietary version of
 it after you quit working for them.

Believe it or not, I don't think they'd care.  I haven't been hired
by the FSF, but I've signed the standard copyright assignment they
require to put your changes in their tree, and it explicitly grants
back rights for me to do whatever I want with it, including use it
commercially.  (Of course, this only counts for stuff I wrote, not the
rest of the app.)

I believe that L. Peter Deutsch was allowed to use the Display
Ghostscript code he wrote in the non-GPLed version of GS (though, I'm
not sure).  That was at least partly funded by the FSF.

 802.11b is okay, but trying to move large amounts of data (like ssh'ing
 mp3's around) tends to cause errors (apparently a known bug; newer
 drivers are a bit better about recovering from this).

I've never had that problem with an Orinoco Silver and an SMC access
point, so that's probably specific to the card or access point. Mine
is just slow.  OTOH, it's usable most of the time... if I want to
shuttle gigs around or edit pictures over NFS, I plug in to
100baseT.  So I'd say it's good to have both.

 Sounds like the difference between the traditional Computer Modern fonts
 (very black, look almost bold) and CM-Super (much dimmer) or something
 like that. Consult a LaTeX guru to be sure :-)

They're supposed to be the same... but unless you had your metafont
mode set correctly, the traditional ones won't look right.  Take a
look at the TeXBook, Art of Computer Programming, or the LaTeX book
to see how the fonts are supposed to look.

# Remove dangling symlinks and empty directories from a shadow link tree

 What could be the purpose of this script?

As described in the script and manpage, it's to fix up a shadow link
tree that was created with lndir.  It's not a general tool!

The lndir manpage describes what the point is:

   The lndir program makes  a  shadow  copy  todir  of  a  directory  tree
   fromdir,  except  that  the shadow is not populated with real files but
   instead with symbolic links pointing at the real files in  the  fromdir
   directory tree.  This is usually useful for maintaining source code for
   different machine architectures.  You create a  shadow  directory  con-
   taining  links  to the real source, which you will have usually mounted
   from a remote machine.  You can build  in  the  shadow  tree,  and  the
   object files will be in the shadow directory, while the source files in
   the shadow directory are just symlinks to the real files.

   This scheme has the advantage that if you update the source,  you  need
   not  propagate the change to the other architectures by hand, since all
   source in all shadow directories are symlinks to the real  thing:  just
   cd to the shadow directory and recompile away.

I think that's already been determined.  He's using a broken

He doesn't seem amenable to using a non-broken gateway.
