I am currently running 9Front on real hardware (mini-itx board with an Atom CPU), I also run 9Front using Virtualbox. I have had issues getting regular Plan 9 to install using Virtualbox. I know it wasn't a problem in the past. Anyway, as I was walking through some sites related to this I found this post: I had a look at Plan 9 and I can only say that their idea of real mode is miles away from Intel's. Plan 9 crashes because it calls BIOS with an environment that only vaguely resembles real mode in that CR0.PE is 0, but segment limits and attributes are totally all over the place. For example they leave the 'B' bit for the stack segment set, which causes rather interesting behavior of instructions that manipulate the stack. That then triggers an extremely obscure bug in VirtualBox which probably affects no other OS on the planet. The Plan 9 folks should probably re-read chapter 9.9.2 (Switching Back to Real-Address Mode) of the Intel 64/IA-32 SDM (Volume 3) and implement their mode switching code the way Intel says they should. This is their code in sys/src/9/pcboot/realmode0.s. The post is located at: https://forums.virtualbox.org/viewtopic.php?f=4t=52431 It was one of very few posts that contained any technical information whatsoever.

Dear Thierry, I use it: james$ bibtex --version BibTeX 0.99d (TeX Live 2010/MacPorts 2010_0) kpathsea version 6.0.0 Copyright 2010 Oren Patashnik. ... In my area (roughly theoretical computer science I guess) LaTeX is a necessity (I have to send the LaTeX source to the publisher) and bibTeX is used by most people to manage their own references. Lots of people include bibtex for their papers on their publications webpages to make this easy. This is the only reliable source of bibtex, 'harvested' bibtex produces laughably bad results. However, I often have to remove the bibtex file and inline the references for the camera ready version of the paper. I'd say that bibtex is usually used to manage a library of references that you accumulate over time. It's not a necessity but an important convenience and one whose use is widespread. If you want to work at all you need LaTeX. If you want to work with others you need bibTeX. You could do without it but nobody else is prepared too. Trying to avoid either would be like refusing to use email. When I say you I guess I mean me :) Best wishes and keep up the good work!

Hi,
My attempt to (belatedly) follow the instructions below has been
hindered by the fact that I don't seem to have the arm assembler 5a on
my i386 plan 9 system.
ls /bin/?c yields lots of compilers
ls /bin/?a yields only 0a and 8a.
Is 5a supposed to be there by default or should I build it from
source? If so how.

If you run replica/pull (or have done so recently), you'll find a new

a diskless cpu server supporting a serial console and gigabit
ethernet. booting(8) and /sys/doc/port.* have been updated to match.
`kw' stands for Kirkwood, the Marvell system-on-a-chip that the
Sheevaplug is based upon. There are more Kirkwood systems on the way.
What's not yet in this port: access to flash memory, USB devices,
memory cards and possibly more. The documentation for Kirkwood flash
and USB is some combination of vague, obscure, incomplete,
unavailable, contradictory and tediously voluminous. If you configure
in the USB drivers, you'll find that there appears to be an
unpopulated root hub, but that may be a figment of the usb driver's
imagination. The EHCI registers do seem to be present and we probably
just need to tweak some undocumented register to make it all go.
If you only been building 386 binaries to date, you'll want to edit
/sys/src/mkfile.proto to at least include the arm architecture:
OS=58
CPUS=arm 386
and make sure all your /386/bin compiler binaries are up to date:
cd /sys/src/cmd
for(i in ?c)
if(! ~ $i cc rc) @{
cd $i
mk clean
objtype=$cputype mk install
mk clean
}
and populate your /arm tree:
cd /sys/src
objtype=arm mk install
You should then be able to build a sheeva kernel:
cd /sys/src/9/kw
mk 'CONF=plug' install # `mk install' will work too
This should create /arm/9plug; see booting(8) to get started.

I checked that the printer is visible: term% usb/probe ep1.0 roothub csp 0x09 ports 2 uhci ep2.0 roothub csp 0x09 ports 6 ehci ep3.0 hub csp 0x09 ports 7 none nil uhci ep4.0 printer csp 0x030107 csp 0x010107 vid 0x03f0 did 0x1017 Hewlett-Packard 'hp LaserJet 1300' uhci I added the following line to /sys/lib/lp/devices: laserjet1300- - /dev/usb/ep4.0/data - post+nohead generic nospool - - - - Then I tried to print something: term% lp -dlaserjet1300 /sys/doc/utf.ps cat: write error copying stdin: request timed out Can somebody tell me what I'm doing wrong? Best wishes, James Chapman

[9fans] multiple pings cause panic
On my new plan 9 terminal running under vmware fusion on my leopard
macbook this happens:
Executing the command
term% for (i in `{seq 1 254}) {ip/ping -n 1 192.168.1.1}
causes
panic: Fsprotoclone: all conversations in use
panic :Fsprotoclone: all conversations in use
dumpstack disabled
cpu0: exiting
Regardless of whether my program was sensible I guess this isn't
supposed to happen. Right?

Sorry, I meant
for(i in `{seq 1 254}){ip/ping -n1 192.168.1.$i}
I added the as I didn't want to wait for one to timeout/succeed
before trying the next one.
Is there a more sensible way to do this from rc? I.e. to kick off a
lot of pings at once and collect the results later.
panic: Fsprotoclone: all conversations in use
panic :Fsprotoclone: all conversations in use
dumpstack disabled
cpu0: exiting
nope. that's the way it's supposed to go.
the idea is that if all the conversations are used up,
then your machine is useless and you might as well
panic.
however, a fair question to ask is, is this limit
reasonable, and is panicing really the right thing
to do.
I was expecting that a panic was a bug and I shouldn't be able to cause one.
I'm running a standalone system here but if I wasn't could I bring
down the server like this or only my terminal?

And it's pure C89 (POSIX is just for the framework, not for the code: I have removed unneeded dependencies). And it's all the latest versions of the programs. So some numbers: - You will need to download a bundle of 4 chunks (I will put all on my website; I think the licence for TeX/METAFONT allows thie): 1) Donald E. Knuth's sources: all the programs; the sources for the Computer Modern Typefaces and the man pages (roff) I have found here and there or reconstructed. = 6 Mb (compressed) 2) kertex_M: these are the tools for the _matrix_ (the vulcan; the node compiling; the cpu) translating from Pascal to C. = 54 kb (compressed) 3) kertex_T: the R.I.S.K. (see below) framework for building TeX/METAFONT, that is the change files, the template Makefiles, the PASCAL-H extensions implemented as a C library. Plus some public domain software: dvips [it is not compiled for now; it's the next in the list] and some auxiliary tools (afm2tfm etc.); MetaPost (not included for now: next after dvips). = 0.4 Mb 4) The R.I.S.K. comp framework (my stuff) that is just a basic POSIX compliant way of configuring, compiling and installing software. Everything is configured via basic parameters file (you should not have to change something here; but it's all sh(1), ed(1), sed(1) and make(1)). = 125kb (compressed; the bigger par in size is D.E. Knuth and Silvio Levy's CWEB [not used here] that I use intensively). So the sources, it is less than 12 Mb uncompressed. And the sources can be (shall be) read-only so you can put them where you want. Space requirements for compilation : you will need about 33 Mb of free space or, at least, 12 Mb of free space if you use the SAVE_SPACE=YES option of R.I.S.K. (in this case, the intermediary products are removed whence the target is built; and when building the package, the binaries are not copied in the tarball, but moved in the tarball). Time: on my old AMD Athlon (686-class), 1250.16 MHz, this takes less than 2 minutes and a half... The resulting package is 8 Mb. But the installation will need a little more, since : 1) The METAFONT plain format is compiled leading to the program that has the right to be called mf(1) since it passes the TRAP test. 2) All the Computer Modern fontes are compiled, using mf(1). 3) The TeX plain format is compiled leading to the program that has the right to be called tex(1) since it passes the TRIP test. Since the work is done for allowing cross-compilation, the binaries are not used on the matrix, but on the target, i.e. at installation time. For the use of the stuff, I will need to put the essential in the document describing the process in the following days. For Plan9, one question: about the group (since for the user it will be ignored). Which group ? I have decided that the stuff will be installed in: - /lib/kertex for machine independant stuff (the macros, but the compiled fontes too). Plan9 users can bind -a to ``redirect'' what will be written where they want. - /$objtype/bin for the binaries. (idem) - /$objtype/lib/kertex/tex/dump/, and /$objtype/lib/kertex/mf/dump/ for the dump of the tables (the compiled version of the macros, that is loaded say when you call virtex(1) mistex(1), this is virtex(1) but it looks to is dump mistex.fmt to load it. The dumps are not machine independant, even not program independant since they depend on options selected at compile time). (idem) To give you a view of what is installed (and possibly where), here is the (generic: for Unices too) map [I need to change root:wheel to variable things) : #== THE MAIN DIR TREE # Everything is relative (for the not man nor bin stuff) to PKGDIR that # one can set as he sees fit. # + d * $PKGDIR/mf root:wheel 755 # This is where we put Computer Modern _sources_ (parameters and drivers # METAFONT's files). # + d * $PKGDIR/mf/cm root:wheel 755 + d * $PKGDIR/mf/mac root:wheel 755 # If you want to ``localize'' messages, look at D.E.K.'s pool stuff. # + d * $PKGDIR/mf/pool root:wheel 755 + d * $PKGDIR/mf/trap root:wheel 755 # Since to create a METAFONT' base
Re: [9fans] TeX: hurrah!
This page and its links maybe be interesting for understanding the relationship between latex and tex: http://www.tug.org/levels.html In my area of computer science all publications are written in latex and for a particular conference/journal a latex class or style file (I must admit to not really knowing what the difference is) is provided and must be adhered to. Everybody I know also used texlive which seems to be the standard tex distribution. It used to be tetex but this is no longer maintained. I would be great to be able to write on plan 9 and I'm very pleased to see the porting effort for tex.

I've used objects a couple times, in places where they do in fact help, but those cases are, in general, not read properly. Using an object in the wrong place, which is most places, does lead to worse code. For most people, using the wrong tool for the wrong job is foolish, but for OOP lovers... The question isn't how do you prove it does reduce static provability, but how do you prove it does not. I can cite mathematical proof that the sun revolves around the earth, but we all know that's not true. That being said, there are studies out there about using the wrong paradigm for the wrong job, objects do come up.
Re: [9fans] Recommended emulators/VMs for P9 install
This afternoon I downloaded a trial version of VM Fusion (Version 3.0.2 (232708)) and a fresh plan9.iso.bz2 and installed it on my core 2 due macbook running OS X Leopard (Version 10.5.8). It works quite nicely, graphics and networking are both working. The only things that tripped me up were I had to delete the IDE emulating hard disk image and create a SCSI emulating before installation and choose xga instead of the usual vesa for the screen. I have had parallels working on several occasions in the past but a recent attempt to get it working again failed. I couldn't even get it to boot the installer.

Re: [9fans] problem logging into a combined auth/cpu/fileserver
Hi Erik, Thanks for the reply. I added the authdom and this is what I have now in /lib/ndb/local: [snip] ipnet=mynet ip=192.168.1.0 ipmask=255.255.255.0 auth=carp cpu=carp authdom=home.net dns=192.168.1.254 dnsdom=lan authdom=home.net auth=carp ip=192.168.1.68 sys=carp dom=carp.lan #sys=carpet dom=carpet.lan If I remove the ip address for carp I get the same error as before. With these settings the terminal (carpet) knows carp's address (which it didn't before): term% ndb/csquery net!carp!9fs /net/tcp/clone 192.168.1.68!564 and I can cpu to carp by: term% cpu -h carp or term% cpu -h 192.168.1.68 If I remove carp's ip from /lib/ndb/local I get the weird error when I try to term% cpu -h 192.168.1.68 But I can still do this: term% cpu -h 192.168.1.68 -u bootes This works for now, but as carp's ip is from dhcp it might change. I'd like this to be more robust so that I can use it on other networks which serve dhcp without changing anything. A bit of zeroconf/ rendezvous would be nice but I'm happy to look up the address on the cpu server console and then type it in manually on the terminal. are you running auth/factotum (factotum(4))? I think so. ps | grep factotum returns two entries and /mnt/factotum is populated. James

[9fans] problem logging into a combined auth/cpu/fileserver
Hi, I have set up a combined auth/cpu/fileserver (using fossil) under parallels. The hostowner is bootes and I created an ordinary user called james. I can connect with drawterm with either user. I can also boot a plan 9 terminal in a parallels instance from the server. If I do this as bootes I can also: term% cpu -h (server ip) from my freshly booted terminal. However if I boot the plan 9 terminal as james then executing the above command gives the error: cpu: can't authenticate: (server ip): auth_proxy rpc write: bootes: cs: can't translate address: dns: resource does not exist If I type: term% cpu -h (server ip) -u bootes whilst logged in as james it connects successfully. Which (to me) implies that the terminal is working properly. I'm rather baffled by the error. Surely it can't have anything to do with dns? James

Of course. I pointed out in my first post on the thread that [...]

family of problems I encounter nor suited to the machines I solve
them on. I cannot exclude other machines and other problems but can
talk from what little I have personally experienced.
I would like to see Haskell fill C's niche [...]
Is it as readily comprehensible to newcomers as C? Are there texts
out there that can welcome a real beginner in programming and help
him become productive, on a personal level at least, as rapidly as
good C textbooks--you know the classic example--do? Is there a
coherent mental model of small computers--not necessarily what you
or I deem to be a small computer--that Haskell fits well and can be
taught to learners? I imagine those will be indispensable for any
language to replace existing languages, much more so in case of C.
According to the designer of F# (another functional programming
language that takes it's syntax from O'Caml as well as Haskell and
even Python), one of the best experiences he'd had was working with
a high school student who was able to modify a solar system
simulation written in F# with no prior programming experience.
(from http://www.computerworld.com.au/article/271034/)
There's books on F# out there, and F# for Scientists.
http://www.ffconsultancy.com/products/fsharp_for_scientists/index.html
There's books on multimedia programming in Haskell out there that
also attempt to show programming to newcomers, but I'm not sure any
of them really assume no prior programming experience.
I think people learning C get one view of the computer that folks
learning assembly really learn to appreciate :-). Folks learning
Haskell learn another mental model of programming as well.
My personal belief is that learning new languages makes one think
about the languages they are used to in a new light, and can make
them better programmers overall.
As you mentioned beginners books for Haskell I couldn't resist
plugging Graham Huttons excellent beginners book Programming in
Haskell:
http://www.cs.nott.ac.uk/~gmh/book.html
It is based on 10 years of teaching a first year undergraduate course
and is certainly accessible I believe. I've taught an undergraduate
course myself using it.
There is also the this book which complements Graham's quite well:
http://www.realworldhaskell.org/blog/
I agree with David in that it is asking the wrong question as to
whether there is a model of a computer that fits with Haskell. Haskell
is based on a different model of computation. Conceptually, Haskell
programs are executed by rewriting expressions not by manipulating
memory in a machine.
A trivial example:
Here's a function to append a list onto a list:
append :: [a] - [a] - [a]
append [] ys = ys
append (x:xs) ys = x:append xs ys
and here we run it (on paper, no machine required :) ) on a some lists
by applying the above rules where the match:
Note: [1,2] is syntactic sugar for (1:(2:[]))
append [1,2] [3,4]
= { apply first pattern match equation }
1 : append [2] [3,4]
= { apply first pattern match equation }
1 : 2 : append [] [3,4]
= { apply second pattern match equation }
1 : 2 : [3,4]
= { just syntactic sugar }
[1,2,3,4]
I wouldn't be as bold as to suggest that Haskell should replace C but
certainly it is a nice language to use in my opinion. Does it explain
how a computer works? No. Does it explain 'computation'? Yes.
