How is that? See an example of closures in Dylan at the end...

The Dylan I'm using (and helping to improve) -- Gwydion Dylan, aka "d2c"
-- produces C code which is then compiled using gcc. That has several
benefits: portability, known quality of code generation, ability to
inspect intermediate C code to verify/understand it (and it's actually
pretty readable -- d2c pretty-prints it and bases the C names on the
original Dylan variables, so it's a bit easier to understand than the
output of Stroustrup's "cfront" was), and ability to leave certain easy
optomisations (such as inlining) to gcc.
It's possible to call back and forth between Dylan and C code, so existing
OS and other libraries can be used seamlessly from Dylan programs. At the
moment you have to hand-code the interface routines in Dylan (as I've done
below), but we're working on automatically producing the interface
routines from C header files and this works for simple cases (not yet
callback functions) now.
> and C++ seems to be there to stay (as unfortunate

C++ is certainly going to be around, and the best language for some
purposes, for many many years to come. It's better than what came before
it. I was an early-adopter of C++ (in 1989), back when it was arguably in
a more rudimentary state than Dylan is today. Much as I saw the potential
of C++ at the time, it was far from a certainty that it would take over
from C as it has.
Stroustrup did a number of things right. I think the most important of
those were link-compatability with C, the philosophy that you don't pay
for advanced features if you don't use them, and compiling to C in the
reference implementation to ensure easy and widespread portability. With
d2c we have the same properties, plus the compiler being "free software"
in the FSF sense. OTOH, Harlequin's Dylan for Windows is free for
personal use, but not "free".
I personally think that d2c is therefore vital to the penetration and
acceptance of Dylan, and Harlequin seem to agree because they are
cooperating with the Gwydion Dylan project and are giving assistance such
as open-sourcing some libraries written by them.
C++ also maintained source code compatability with C, but Java has shown
that the market will accept deviation from this. Dylan's syntax is not as
close to C's as is Java's syntax, but it's not so far away as to be
shocking to anyone who has programmed in the C/Pascal/Algol family.
Unlike, for example, SmallTalk, Lisp or FORTH, each of which can send C
programmers running screaming.
I tend to think that in terms of adoption Dylan today is about at the
stage that C++ was at in 1990 or so. Back then, C++ was nearly a decade
old, but there was basically just CFront. Zortech C++ was out, but
Microsoft, Borland and Symantec probably didn't even have C++ on their
horizons yet -- they certainly hadn't released anything. Dylan is in much
better shape now than C++ was then in as much as the language definition
is far more stable and complete. The implementations aren't 100% there
yet, but the definition is stable. Dylan is also better off with standard
libraries. The Dylan equivilent of the STL was defined alongside the
Dylan language from the start, and integrates with the language much
better.
The other major thing needed is a GUI library. Apple had a pretty nice
one in their Dylan Technology Release in 1995 (and the development
environment was *awesome*), but it was very Mac Toolbox-specific.
Harlequin's DUIM is hopefully more portable, and there are plans to port
it to d2c/Unix.
You asked about closures before. I just happen to have been implementing
code for PowerPC (x86 was already done) that allows closures to be passed
out to C code and used as callbacks. Closures already worked within a
Dylan program, of course (as did non-closure callback functions), but to
pass them to C functions that expect just a simple function pointer we
need to create a machine code thunk/trampoline at runtime and pass the
thunk to the C program.
I'll include one of my test programs below.

Subject: Re: ping
Do you have any type of firewalling running on your Linux system (ipfwadm
or ipchains), which would be blocking ICMP packets? If so, remove the
deny all filter/chain on ICMP packets. If not, your ISP may be running
filters at their routers, which prevent ICMP packets from being sent. Or,
the host(s) you are trying to ping have ICMP filters in place.

Whe client is running NT, you need to install special software to use
'transparent' proxy. You need to set your Linux box to use transparent proxy
(check http://support.microsoft.com/support and search for transparent
proxy), or you can configure SOCKS proxy on NT server if you are running
MS-Proxy 2.0.
Good luck!

I think all you need to do is find out the ports the poxy is running on. I
can tell you that the default port for MS Proxy for NT is 80. I have it on
my NT comp at home, but it doesn't require a Proxy Client. You just
manually set the proxy for the IP address and port number.

Yup. Works well. However you have to set it and pppd up properly. I
suspect you are trying to use the login option for pppd. in that case
put the line
* '' *
into /etc/pap-secrets. This uses the null password for eveyone, and
after this matches everyone, the login option then tells the sytem to
use the passwd database/passwords for login.

I think there is a website called www.samba.org. You need to install Samba on
your Linux box and edit the /etc/smb.conf to be a domain master, do domain
logins, etc. I have my own WinNT box, so I don't use Samba for that purpose,
therefore I am not going to be that great of a help to you, but all you need to
find is documentation on Samba (can be found in /usr/doc/samba-x.x.x.x).

It was very exciting to get into the internet with my Linux OS. Great

Where can I find the scripts. Can anybody send me an example of scripts
to dial and disconnect from their ISPs? Also how can you give non-root
users access to use these root-owned scripts.
The reason I want to use the scripts directly is to not have to
"Activate" the my ppp0 interface from withing the 'netcfg' utility.
Ideally I'd like to be able to call a script what would get me into the
internet! :) I hope I'm not asking for too much. :) Linux is great. I

I had all the problem you can ever imagine... Cards were not recognize ,
then yes , after only one of the two computer with exactly the same

Which card are known to worrk the best , with linux ...What model I can
buy with eyes close , and that will works without problems.... It is
very important for me to establish this fast network , with my computer
, so if , someone can help me choosing a card, it will be coool....

Subject: SOCKS5 and RH6
Date: Fri, 25 Jun 1999 14:49:32 GMT
Hey folks,
I'm having a little trouble setting up SOCKS5 on a multi-homed
machine.
First let me lay out the scenario for you. I have a RH6.0 machine with
two NICs; one to my cable modem service, one to my internal(home)
network. I want to set up the RH box as a packet filtering firewall, but
in the meantime I would like to set up a SOCKS5 server. I'd like for my
internal machines to pass thru socks for all traffic to the world but
I'd also like to prevent anyone on the outside from having access to the
proxy. I've read the docs on the socks.nec.com website and tried the
socks5 RPM and building from source. I simply cannot get socks to work.
When I run it like "socks5 -o" to get a one-shot with debug prints and
try to connect to a website with Netscape it says:
10730: Config: Reading config file: /etc/socks5.conf
10730: Interface Query: if0 addr/mask is 0100007f:000000ff

10730: Auth Failed: (192.168.2.2:1077)
10730: Proxy: done cleaning up
It's quite possible that I just don't understand the config
rules for
socks5.conf. The documentation and man pages are a little ambiguous
about how to use the permit, auth, and interface rules. I would really
appreciate it if someone could give me a hand with this one. Most of the
posts to USENET which appear to be related to this problem are either in
German or Dutch(?). I don't trust babelfish to get the translation
correct given the technical nature. Thanks.

Not using DNS. No matter how you set up your DNS, in actual operation it
must return one of your five static IP addresses to the remote client
(somewhere out there). That remove client will not be able to see you using
a private IP address. Not much room for maneuvering there.
If you want to have multiple hostnames, like www.mycompany.com and
www2.mycompany.com, I know you can put them on the same box with Apache, but
that only works with the Apache web server. It wouldn't help you with say
IRC or something else.
Good luck.
