We have working scanner.

You can use the Wt25,WT36,Wt42/48 and WT36DS Scanner.

Scan via Touchscreen and upload the images to a Plan9 cifs
networkshare.

The scanner ist connect via 1G ethernet.
On the Touchscreen  is an Option "Scan to network".
The scanner scans direct to a cifs share (aquarella on plan9).
No need for spezial software except a Cifs Server.
The scanner use smbclient.

I checked out the image access site, and it looks like you can scan to
FTP, email (built in MTA?), along with the smb method.
I actually think thats pretty nice.
What on earth is free business contest law (FBCL I suppose)?  Does that
mean if I only make parts for Ford motor cars, and I completely ignore
GM, and also the vast league of Kit Car DIY'ers, I am evil?
I like the book scanner idea though, you should jump on that.  Much more
elegant in my opinion to the 'book open, face up' with camera's from
afar method.

That's neat. It makes sense too, using ethernet almost always seems a
better deal than using USB. It's so cheap to put a network stack and
ethernet into these devices, and the network stack is doubtless less

I definitely agree with this part of it.  However, I would much
rather see the higher-level protocol be something that is simpler
and not tied to any commercial interests.  I don't even object
to having cifs as an option.  But when did it become popular
to say that ftp should not be an option for transferring a file?

The basic little flatbed on the website can scan to FTP. I'm not sure
why the original poster chose to mention SMB and not FTP, but it's an
option.

Which is good, because I for one have never been able to get aquarela

I have used it quite a few times in the past. however every so often
I do find some weird part of the SMB spec which is not implemeted. That
said it usually works well.

I am happy to look at reports of problems as I have had dealings with
the CIFS protocol in the past.

I'm sure it did *at the time*...

But have you tried to find even an embedded nano board that has in-bridge-chip
audio codec's lately? Where 'lately' is now around ten years-plus? And
'speakers' have becoem tiny, effective - and also very cheap?

We've been chopping-off audio jacks on C3 & C7 MB for years to make quite decent
low-power 1U servers... too tall for the case otherwise.

PITA, that, but we don't use enough of 'em to order them 'unstuffed'.

ACK .. but time marches on, and there *must* be a few 'shareable' things more
current than SB equivalents. How / why not get those examples onto the web page
as add-ons if not more germane replacements?

DISCLAIMER:

My audio gear largely sez 'Marantz' on the front panel, some dates as far back
as 1968, only the CD drive is newer than 1975, and CD aside, has SQRT-FA to do
with computers. Still sounds sweet though.

If Plan9 can 'plumb' a remote sound card, (a questionable example long

'Questionable example', as I've never quite understood how I'd be able to hear
the output of a sound card whose physically-attached speakers where half-way

it isn't plumbing, but export/import, and it's useful.
i had a usable sound system on my r3000 indigo, but my PC had none.
on the pc, i imported the indigo's /dev and played sounds that way.
i could imagine uses even a continent away (alarm system imports remote

Welll - in the same room, it would seem 'sneakernet' would do well enough. Point
of fact, I use three kdb,vid,mouse and ... a swivel chair... less confusing than
sharing/switching among three disparate OS'en.

;-)

And I've actually considered remote audio I/O as part of a system for monitoring
a house that sits empty for months at a time, and responding to the doorbell ..
intrusion, et al ... but.. 'edge cases', both, if ever were. Easy enough to do
without Plan9. 'Too easy' to be fair.

'export/import' applied to remote resources - especially 'scarce' or expensive
ones (sound cards no longer are..) that could *send back* the results might make
a better present-day example.

If we could identify a few...

Couple of thoughts:

- hardware crypto devices  (cheap and cheerful in recent VIA CPU, seldom seen
otherwise)

- fast, specialty (expensive) graphics processing engines for storage to file,
or streaming-back not (necessarily) remote display. Ray tracing comes to mind...

- a 'ration' - free or purchased - of grid or supercomputing resources? (several
experts here - I'm not among them)

In any case, given that audio codecs are near-as-dammit ubiquitous on commodity,
and even 'server grade' and 'embedded' system boards these many years, I think a
better example than sharing a Soundblaster-equivalent is overdue.

I'm well aware that 'marketing' Plan9 is not really on anyone's radar here ..
but there could be a bit more done to convey the availability and value to the
like-minded potential fellow-travelers [1]. One benefit might include more
current device driver import/devel..

I've had responsiveness issues when the viewing machine hasn't enough
CPU power to decode the screen data in real-time. A lot of power
seems to be needed, my PDA, a 416MHz ARM can't cope with any
compression at all, I have to limit vncviewer to copyrect and raw
encodings only. Encoding doesn't seem to need half as much CPU power.
I ran Xvnc on a headless server with a 400MHz AMD K6 with no issues
that I recall.

All that gear was using either TightVNC or the plain vnc-x.y.z.tar.gz
from RealVNC. When using Vine Server on a 466MHz Apple screen updates
are not really adequate,  while the mouse pointer lags if I use the
VNC server supplied with OS X Tiger on the same machine. x0vncserver
is a known problem server which I haven't used, IIRC it basically
works by taking screenshots continuously and sending those.

Now I don't have any expertise with VNC, but decoding anything, is
supposed to take less time than encoding it. I would check into that.

The Java tightvnc client works fine on my little eee pc, so I would think the
native client should run well enough on a toaster.  Maybe it uses floating
point and the ARM pda in question doesn't have hardware floating point.

Java sometimes does turn up trumps where C code struggles on machines
which were recently considered powerful. Other examples would be web

YouTube offers it as an option. Perhaps the Java TightVNC client

I personally would like to see a lot more in the way of remote
resource access using 9p and I'm working towards that by writing
software for windows, linux and android.  Its a slightly different
use case than typical plan9 setup: ie my terminal has some
devices and I push them to a cpu server so programs run there
can access local resources.  Instead you have resources on several
machines that you own (and who doesnt own several machines these
days, heck even my non-tech relatives do) and you import them
to use them as necessary.  I've been playing around with sound
a lot as a starting point but I am hoping to move on to other
devices soon.  In my current prototypes I can import sound devices
from (android, windows, linux oss) onto another (android, windows,
linux oss) machine and either replace the current audio subsystem
or offer the remote audio as an additional audio device.

Why should all of your machines need a dvd drive, sound card, sdcard
reader, etc.?

I intentionally avoided this one because two things that modern

Actually, they have ...

'Big iron' quite aside [1], it was common (at least) as far back as CP/M 2.X to
share peripherals such as prom-blasters, text-to-speech gear, terminals, serial
and parallel ports across multiple machines. Not everything needed was in the
as-shipped 'OS', but it was not hard to code the rest.

By the time Netware, IBM OS/2 (and perhaps Win-?? - not my area of expertise)
came along it was tick-the-box easier to share, for example, a modem or scanner,
just as easily as a printer or storage device. IOW - streaming 'near real time'
devices as well as spooled or (actual) file-based services.

Plan9 didn't 'invent' any of this.

Plan9 just prioritized it and provided a more appropriate infrastructure and
toolset to make for easier and more ubiquitous use of it all.

That one or more folks are now seeing a need to reinvent that particular set of
wheels is curious, as it never actually went away - Plan9 or otherwise.

Perhaps the old saw about 'ethnics' (pick yer own favorite..) and garbage.

military career to lay the groundwork for the Plan9 user interface.

I think this sharing dropped off drastically at some point in fairly
recent history. I took a look at Apple's list of services and devices
which can be shared with a checkbox or two; it really was a much
shorter list than I thought, and I'm sure the most convenient Linux
distro has a couple less items again.

Windows I'm not so sure about, but I don't think you have to go back
many years to find the time when Windows 98 was the most common
Windows, and what did that offer to share? Printers and files only,
if I remember right.

I was running diskless Windows in 1995; it wasn't pretty, but it could
be done.  These days you can run XP+ diskless if you have the right
Windows Server and installation tools fu.

Don't get me started on diode plugboard 'ROM', mercury or nickel-iron delay
lines and 'upgrading' to mag drum memory now...

Time was when a power user's *personal* computer (~US$ 25,000+ in 1968-69
dollars [1]) had the full-house complement of RAM it could hold.

All 8 kilobytes of it.

;-)

.. and we controlled satellites and serious weapons systems with those as well
as digitizing electro cardiograms and such.

More seriously - there's another probable reason Plan9 hasn't found greater take-up.

No need to share when there are enough sheep to go around...

Heh!

If you'd ever dropped a deck of punched *cards* you'd have thought paper tape
was a huge advance, and more durable mylar even more so....

;-)

Wasn't all that slow, either. Mannesman-Tally punched it at 300 cps and upwards,
many optical readers read it back at over 1,000 cps.

Actually, back when I was a little boy, I played a bit w/ some
learning toolkit which had spunchcards, for simple things like
switching signalling lights, etc (and yes: I managed to build
an optical reader, yeah :)). But I wouldn't consider this as
"computing" yet ;-o

Yep. Around that time we ran diskless win-3.x and win95 via Novell.

It's certainly possible to run OS X diskless, and knowing Apple it'll

And somebody always mentions toasters! Or coffee machines... :D

Actually, yes it does say a lot about a toaster's elegant simplicity:
a toaster only has parts to do the job intended. At a minimum a
switched heater, a sprung sliding bread carrier which also switches
the heater, and a thermally-releasing latch for the slider. I have
seen a toaster without even that much complexity; it had glass sides
so you could see when your toast was done how you like it.

Actually there is a link here. Things to share are increasingly
bloated, and applications strangely seem to need access to every
feature of the shared entity. 9p could perhaps help by presenting a
device model with files for different capabilities, or something like
that, but it is only half a solution. OTOH perhaps the need to access
device features is not really strange. Requiring a whole postscript
interpreter on your printer could be seen as just as strange, it was
certainly very expensive to do a few years ago.

There is a toaster that burns a picture of a raincloud, sun,
snowflake, etc. depending
on the morning's forecast. There is also a coffee pot you can control
via ethernet.

The coffee pot runs windows and there is a virus that causes Coffee
Denial of Service
on it.

I doubt anyone would be foolish enough to put an 80x86 in a coffee
machine. Yes you could run WinCE, but without the 80x86 your not going
to suffer from the hoards of virus's.

I'd like to see the day someone gets Linux or NetBSD booting on a
coffee machine.

Once upon a time we crammed a PPC board into a stainless steal toaster as a demo platform with the LCD popping out of the slot like a piece of toast.  I thought i had pictures, but can't for the life of me find them.

I once used a microwave designed that way. Couldn't find the meal on
the list and had to manually set time and power with 3 digital buttons
:(
It looked nice though. It was painted whine red with black/dark-brown
shades just like my eyes.

You have too much faith in humanity. It runs on a Via x86 clone:

http://www.microsoft.com/presspass/features/2009/jan09/01-09cesfugoo.mspx

The article doesn't mention which flavor of Windows, but I don't think
WinCE runs on x86, does it?

Why not ?

About a year ago I've built an alternative firmware for some tiny
WLAN router which was based on an i386 clone SoC (IIRC made by TI).

Old-fashioned x86 isnt so bad for embedded as some might think.
If you don't need high data rates (and things like PCI), it's
relatively easy to build a board manually ;-)

hmm, I think the Toasters work w/ SSDs or maybe some kind of
nano corememory, at least the mechanical ones. This could also
their extreme suspectibility to certain radiations. But no idea
what causes that effect on the humanoid ones ... ;-o

Linux runs fine diskless. Done it already 15 years ago ...

I've done Linux over AoE, that was flawless once working. Lack of AoE
aware installers made it interesting.

Plan9 is a fiddle too

I didn't try the MacOSX or Windows AoE initiators.

You need plenty of Foo to do any of them tbh.

we found it's a lot easier doing it like

discuss any of it.

Did you find 9p adequate for the resource sharing you
did or did you have to alter the protocol or augment it
with other protocols?

Did you use the normal plan9 authentication mechanisms or
did you explore other authentication alternatives?  Were
all machines in a shared authentication domain or did you
support multiple authentication domains?

What did you do about machine or resource discovery?
Is there a mechanism to discover when machines or resources
are added or removed from the network?

What papers do you recommend looking at?

i wasn't talking about aoe.  but since you are, what
exactly is difficult about the plan 9 aoe driver?

the installer, or was last time I looked, I did try to make one but got
so far and decided on a "better way" which is on my large pile of todo.
I made a "install to this drive" script that did away with the installer
completely but I haven't tested it much yet.

good point.  i'll take a look at that.  installing isn't
something i typically do.  let alone onto aoe.
really just need to add a configure drive step.
