Hi all squeakers,
I've ported quite a few languages to the nslu2 optware (see http://nslu2-linux.org for detail). The only major language not running on the "slug" is Smalltalk.
Any idea where to start to get a headless squeak running on the slug?
I vaguely remember there is some package allow one to use web browser as a Smalltalk browser. Combined with a headless image, that would be a fun environment to experiment.
Any pointer would be greatly appreciated.

Start with squeakvm.org - suck down source, compile a VM. The VM can be built without X, or you can run it using "-headless" or similar options. If you have a decent Linux I am guessing you are home free, perhaps someone already have done it.
And btw, if you have VNC that works dandy too - so you can actually run an image with the UI, but remotely. In fact, Squeak has a VNC included even (as an addon from SqueakMap). We (web app devs) use VNC all the time.

I quite like the list near the top of the page:-
" Every community has its own set of rules. Here are ours:
You will search the wiki first here and read the FAQ before asking questions. You must read and follow the steps in the README file precisely when flashing firmware. Those who ask the questions, update the wiki when they get the answers. Those who complain about the documentation, update the wiki to make it better. Friends don't let friends flash custom firmware without confirmed RedBoot Upgrade Mode access. Friends don't let friends flash custom bootloaders without confirmed JTAG access."
Maybe we should adopt analogous rules wrt our community education needs.

That's just a simple way for getting very few new people into the boat.
For different reasons (not being sexy like squeak) the german forth people suffer this thing. I'm in that club (just paying member) for over a decade and they just get older and diminish.

Those (understandably) frustrated by the always repeating questions which could be solved by just searching the wealth of information about Squeak just stop replying and use their mail filters.
Otherwise I fear we have to face the biological solution.

Fair points Herbert. Perhaps if the normal response to 'frequent question' by a newcomer was a polite message like:-
Hi XXXXX, I think your question might be answered by http://foo.bar.com/FAQ/ 1.html so please take a look and see if it helps. If it doesn't, then please let us know so we can help and improve our knowledgebase.
... then we might have some success.

I agree and and my patience is also limited.
And personally I don't mind if someone tells me "I talk to you AFTER you read the FAQ".
A visit from friends kept me from reading mail.

Thanks Göran,
I'm glad to tell you all that squeak has been ported (cross compiled) to run on the nslu2! (266MHz big-endian ARM with 32MB RAM -nodisplay -nosound)
0 tinyBenchmarks '14692378 bytecodes/sec; 551451 sends/sec'
The cross build makefile and patches are checked in at http://cvs.sourceforge.net/viewcvs.py/nslu/unslung/make/squeak.mk http://cvs.sourceforge.net/viewcvs.py/nslu/unslung/sources/squeak/
Since "optware" supports a couple of other small devices, it should not be too hard to get squeak running on them. The binary package for nslu2 is at

In fact, I'm running the seaside 2.6 image thru the built-in RFBServer, not fast, but quite usable.
If only we had a Seaside/Ajax version of the SystemBrowser, Transcript & Workspace, then we can remove lots of the GUI stuff. What do other squeakers think about this idea?

Yup, that's pretty much exactly what I used to get on my old Acorn RiscPC SA 202MHz machine, so no surprises there. You might get better figures in the larger benchmarks because the slug can't possibly have a memory system as primitive that the RPC (16MHz 32 bit wide bus meant for 1992 era RAM) even if they tried.
You'll find that performance is ok for everything but morphic but since I'm reasonably sure the slug doesn't have graphics of its own that probably won't be a problem.

Hi,
the nslu2 seems also to be supported by the openembedded project. I did get the system to compile a 3.4 VM for the Simpad and intended to port the 3.8 VM for Qt (Opie) and for fbdev but this is currently on hold due to massive timeout problems (my time) and autoconf difficulties.

The nslu2 port I did is for optware running unslung firmware. My only two slugs are running unslung fw and debian respectively. When I get my third slug, I'll probably run the openslug fw.
We often trade recipes for cross-compilations between optware and openslug. So it should not be that difficult to create a .bb file. That would probably open a wider door to more devices.

Some performance comparisons between my PocketPC, my desktop and the nslu2. I ran the Integer>>tinyBenchmark on my 400 MHz Intel PXA255 PocketPC (little-endian ARM, 64 MB RAM, Turbo mode). Results are:
18048505 bytecodes/sec; 627490 sends/sec
If the speed is scaled down to 200 MHz:
9216589 bytecodes/sec; 312981 sends/sec (no surprise)
However, the nslu2 almost reaches the 400 MHz performance of the PXA255!

On my AMD XP 2800+ 512MB desktop running Linux 2.6:
225153913 bytecodes/sec; 7844410 sends/sec
Despite of the tremendous difference (12.5*), Squeak is definitely usable on the PocketPC (speedwise at least), after having done one minor adjustment: changing the SystemWindow maximize method so that the maximized window fills the entire screen. You can even do development, just use Class browser instead of System browser.
