<br>
OK, you've motivated me for another time investment.<br>
Do you use the AOS graphical interface? Do you run the<br>
Oberon application or process in AOS?<br>
<br>
My most recent foray was to put UnixAos on the OLPC XO-1.5.<br>
On the little screen, text is too small to read. Next I can install<br>
it natively and try increasing the font size system wide.<br>
<br>
Apart from support for USB and better networking capabilities,<br>
what are the most significant advantages of AOS over NO in<br>
your view?<br>
<br>
As you suggested months back, I installed xmonad on<br>
the Debian system and got a menu band across the top<br>
of the screen. Couldn't get a terminal window open.<br>
<br>
I don't ignore your advices. Just slow plodding<br>
through the details.<br>
<br>
Regards, ... Peter E.<br>

Most linux: X can step the global-magnification.<br>
What WinManager do you use with Debian?<br>
I've moved from the RedHat-family [Mandrake, FedoraCore]<br>
back to Slackware, and blackbox/fluxbox is beutifully compact<br>
and fast compared to the default KDE-4, which is a monster.<br>
<br>
I'm expecting to receive 2 Raspberry Pi soon; one with the<br>
default Debian installed. But if can't install the superior<br>
text editor/s of ETHO, the system is half-lame for me.<br>
<br>
> Apart from support for USB and better networking capabilities,<br>

<br>
That's exactly the RIGHT question to ask.<br>
<br>
I've got a 500GB Toshiba USB2/3 /dev/sda for backup.<br>
<br>
Right now I'm in LEO, editing your Mail.Text which I received via<br>
the same old familiar ETHO: TextMail utility from the 90's.<br>
LEO has the old look & feel.<br>
<br>
The main difference is that LEO handles full PATH designated files.<br>
So that eg:<br>
EditTools.OpenUnix /mnt/toshiba/usr/local/speech_tools/config.log<br>
opens an ETHO TextFrame with the file on the Toshiba-USB-drive.<br>
I don't know how. But I suspect that LEO just <hooks into some linux<br>
socket>.<br>
<br>
Remember *nix is magic.<br>
So imagine what it's like having multiple N-O terminals,<br>
where EACH one can access all the files that *nix can access,<br>
and in 3 formats: ETHO, *nix, DOS.<br>
<br>
One advantage of opening LEOs in differnt dirs, is that if<br>
you want to work on 4 texts in that DIR, eg:<br>
->System.Directory /mnt/toshiba/usr/local/speech_tools/*<br>
/mnt/toshiba/usr/local/speech_tools/<a href="http://configure.in" target="_blank">configure.in</a><br>
/mnt/toshiba/usr/local/speech_tools/install-sh<br>
/mnt/toshiba/usr/local/speech_tools/HelloTst.cc<br>
/mnt/toshiba/usr/local/speech_tools/config.status<br>
<br>
These are inconvenient long-path-names, because I'm<br>
accessing them from:<br>
-> System.CurrentDirectory =`pwd` which is: /usr/local/bin/LEO<br>
<br>
But if I opened a new LEO, in /mnt/toshiba/usr/local/speech_tools/<br>
then the filenames would be more managable as:<br>
<a href="http://configure.in" target="_blank">configure.in</a> install-sh HelloTst.cc config.status<br>
<br>
Besides if you're working on 6 projects, each in their own dir-tree,<br>
it's better to have a separate LEO for each project, based in the<br>
relevant dir-tree.<br>
<br>
So I use LEO to do a lot of my linux work.<br>
<br>
Could your substitute for VNC allow direct pasting from a `man`<br>
to an ETHO-text, like this Mail.Text?<br>
<br>
And can A4 do so?<br>

I'm on this list now for many years and I still haven't got a clue!<br>

Folks,<br>
I only poked at AOS some years ago. Its based on Active Objects, right?<br>
If so, how many of you actually use that feature of the language/system?<br>
Does it make for a significant difference (in any aspect)?<br>

I tried it! Everything I touched in it seemed to be broken, or<br>
half-done half-baked.<br>
<br>
The web browser was painfully slow, etc etc<br>

Duke,<br>
<br>
you should not forget that A2, or AOS as it was called previously, was a<br>
research OS in the first place. A2, running on Active Oberon, features<br>
multi-threaded (multi-core / multi-processor) applications. The kernel<br>
is as small as can be for a multi-core environment. No heavyweight<br>
processes, only fast context switches etc.<br>
<br>
Things have progressed meanwhile. A2 and Active Oberon (and the newest<br>
programming model successor in use for software-hardware co-design<br>
called "Active Cells" ) are in use now in both, education and industry.<br>
<br>
You are right about the web-server. It is neither particularly fast, nor<br>
is it maintained. I never use it.<br>
<br>
I will neither try to defend A2 or Active Oberon here, nor will I try to<br>
persuade anyone to using it. Enough things to do on the forefront and<br>
too little time for service.<br>
<br>
Regards<br>
Felix<br>
