AltME groups: search

this also means that you don't need a physical server machine to 
run an AltME server.

I'm still confused then.

Suppose you create a new Altme -type world. I join it. We're both 
on dial-up. We both log off for the night.

I go to an Internet cafe (ie a different machine) and want to logon 
to the Altmt-type world as me.
How do I find you? How do you know its me?

ok, i ve followed some discussions about agg and i can only dream 
about what can be done with it.  I know that R3 is a major re creation 
of the virtual machine, but as a programmer i cant wait to see a 
version of rebol that interest the corporate world....  I	ll try 
to help as far as i can

I doublechecked on a different machine. No problems.

It works on another x64 machine, so it's really strange that it doesn't 
on my main machine. I'll try to figure it out. In the meantime, nice 
work Oldes!

It's really interesting the different approaches taken around that 
time. I was studying and writing UI frameworks in the early '90s, 
starting before VB and Delphi came out. It would have been cool to 
see a NeXT machine in more than magazine articles. The IB model is 
gaining acendancy with the newest platforms now: OS X, WPF, Glade 
(don't know about the Qt stuff). Most of the corporate-backed Java 
tools still follow the Delphi model though. Flash still seems to 
follow (an advanced version of) the VB model, but Flex probably doesn't.

Same here. I use hibernate every day and it never causes View to 
crash on my machine.

I rebooted my machine... a laptop I rarely need to reboot.

denismx:  I'm not following very well.  Is your problem with the 
Debian server as I have this working for a family server hosted on 
a windows machine as I'm sure many people here do.  If you want to 
try again on a windows OS, place a shortcut in your startup folder. 
 In the target field the command should be similar to this...

another script can delete that executable while the executable is 
running

 <-- it appears that this only works when deleting the application 
 via an SMB share, not directly on the Windows machine...

I've seen this error twice now, on machines where AltMe is connecting 
to this world. Once on a machine where the world has been for a long 
time, and it caused it to resync everything; the second time, just 
now, on a virgin machine:

<< Any rules about who can post into what groups?>>

If you can see a group in the groups list, then you can post into 
it. If your posts are not appearing then either:

* it has been lost -- if you have a flakey connection, Altme will 
try to upload the message from your machine and if it discovers it 
needs to reconnect, it will do so automatically and then THROW YOUR 
MESSAGE AWAY. All you see is the "reconnecting" message. You are 
not told your message has been discarded.

* it has been recieved, but is not rebroadcast to everyone. Some 
people see it withing seconds, some do not unless they later post 
inot the same group This is the resync problem refered to above.

How does Altme! keep track of  a client's cach of messages? Does 
it update based on differences from the messages on hte client machine 
or from the server? What I want to know is: if I use altme from two 
differnet computers will I always get a full update when I log on 
or will I lose messages if I loged on a different computer before. 
I'm having trouble updating on a computer I  recently installed Altme 
on. I am not able to get many of the groups to download the old messages.

Re: Serving multiple worlds. If I have a shortcut to start a second 
world, e.g.: 

	path/altme.exe -s "worldname" -p 5401


On the same machine where a world is running on port 5400, the second 
world starts fine, but the Check World tool reports that it's on 
Port 5400, and attempts to connect go to the other world (which *is* 
on port 5400).

Has anyone else seen this?

I have registered 10 of 10 possible things for FF, but it still does 
not work. I noticed there are still 3 entries registered with IE, 
one of them being .url, but it can't be deselected (is greyed), even 
if I am admin. I really don't like Vista, it is complete shit. To 
display file associations it took 20 secs here on 2GB RAM, Core Duo 
machine ...

In order to run your own world, you need to DST-NAT (forward) particular 
incoming port to your machine.

and apparently multiline messages don't work on this machine. strange.

Yes, the other thing is that it may be served from anywhere, so how 
well a world scales depends on the machine running it. If you want 
the best scalability, serve it from a good machine, or have them 
host it.

I also had problems with worlds that were not 'reserved' running 
on theh same Win98 machine.  I had frequent drops of the worlds... 
the world server thought people hadn't been on the worlds in 90 days 
so the server released the name.  This happened really frequently, 
even though the worlds in question were accessed every day or every 
couple of days.

What exactly can cause "AltME Error: Registray cannot load dataset 
files: 2" during startup? I'm getting it so many times on various 
machines, I'm starting to think it's a bug in AltME rather than data 
file corruption by something else. Whenever it happens when I'm trying 
to log into a specific world, it's "jinxed" and I can't log into 
it anymore on that machine. It does not help to just delete the whole 
dir, redownload AltME and start from scratch.

it seems also to happen mostly when changing world from one to the 
other. I haven't been able to run multiple AltMEs on one machine 
for a long time.

I havne't seen it, but I recall the available server ports on one 
machine to be 5400 and believe it to only go to 5405, but could be 
wrong.

Brock, yes that's what I thought.  I'm wondering if the problem is 
that I requested "Too many Servers" from the Altme world-creator 
itself. I'm talking about starting worlds that I have consistently 
used for years and one more (to make four) that is new.

You've given me another thought though, maybe my own machine is causing 
this to happen(?) At this point I can only run two of the three existing 
worlds and never the newest one. Hmmm.

It is also placed in your config files on local machine - however, 
no matter how you try, if you registered new world without old ones 
running, altme registers it to existing port and then you will face 
strange situation, when your client is choosing to new world, but 
is connected to another one ...

AltME feature request.  Include the date/time as a second column 
a group was last updated.  Since we don't have the ability to synch 
what was read between each instance of AltME that we read, having 
the last date/time listed we could quickly select through the groups 
we have already visited in a previous session on another machine. 
 Although synching what was last accessed would be the ultimate fix. 
:-)

sorry, my issue was with re-creating a world.  I had multiple worlds 
hosted on the same machine at one time and I cheaped out and didn't 
register the world for $10 US per world.  When the worlds expired 
after 10 days of no usage (which never happened, but they expried 
anyway), I had to recreate the worlds, the order was important in 
that scenario.  Sorry for misleading you.

I was running multiple servers on a Win98 machine, so don't know 
if anyone else has had a different experience on the more recent 
Win OS's.

I haven't found the magic steps to make this work reliably either. 
I was able to make it work sometimes by manually starting the worlds, 
and I though had it working from shortcuts, but then things would 
stop working. At some point I gave up, and now just host one world 
per machine.

Report for those that are trying to run more than 2 world servers 
on one machine - we were unable to register second world, even if 
the first one was running, and hence TCP port 5400 was occupied. 
Last weekend I did some experiments, and my conclusion is that if 
you need to start secondary world


1) make sure that your primary world is running - this will prevent 
registration process to use first (or simply lower TCP port). AltME 
starts with using ports 5400 and higher ..


2) block your ports (NAT) on your firewall. Simply put, there has 
to be some bug. Even if my primary world server was running = port 
5400 was occupied, my new world was assigned port 5400 too. Simply 
put - it has to be AltME server at SafeWorlds, which connects back 
to your site, and mistakenly uses 5400 to check. Then it registers 
5400 for your new world. This is my speculation. But the solution 
really is to block your prior (already being used) AltME ports on 
your firewall (NAT)

So - I am now running multiple worlds on a single machine succesfully 
....

What happens if someone changes the machine's clock while you wating 
for a length of time ?

Is it possible to find the IP address of a machine using a proxy?

Do you mean this ?:

Terry's machine ---- ( internet ) ---> proxy machine ---> target 
machine
where the target machine is the ip you want.

I am supposing a remote machine has connected to a service of yours, 
and you want to know if you can inspect the port in such a way as 
to obtain the ip of the remote machine, even if it is behind a proxy.

Purely a matter of opinion.... or raather a couple of opinions...


Should now be immutable?  Of course not unless you want to reset 
the time on the machine for testing.


Can a timeone take the value 8:01 - not in real life at the moment 
- I  came across this odd behaviour when investigating the difference 
between mydate/zone: and to-date. I found out that there are a few 
:30 minute timezones and a couple of 0:15 (or 0:45) time zones, the 
rest were all hours.

Or do you mean the REBOL process' environment that is inherited by 
the subprocesses started by CALL (assuming that CALL internally passes 
along the current environment to its subprocesses)? Or do you mean 
the environment of the parent process?


Every started process is passed an environment, usually a copy of 
the parent environment (sometimes with some modifications). On Windows 
(NT kernel, not 9x), the initial environment is a combination of 
variables associated with the system (or machine), the user and volatile 
values, in that order. The initial values of these variables are 
constructed from data in the registry. Once these variables are constructed 
and compiled into an environment, this environment is passed to a 
process. Changes to the environment of that process (with getenv 
and setenv) don't affect the environment of the parent processes, 
and certainly don't affect the global values.


To change the initial environment variables, you need to change them 
in their original registry entries. You can either do that directly 
or through using external applications. Keep in mind that changes 
to these initial values won't affect your current environment, or 
those of any running processes, as those environments are already 
set and can only be changed internally.

Environment variables are based on values of the following registry 
keys, for each type:

- Local machine: HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Environment
- Current user: \Environment
- Default user: HKEY_USERS\.DEFAULT\Environment

- Volatile (probably should be treated as readonly): HKCU\Volatile 
Environment

You can check in regedit for your current values. Remember to use 
REG_EXPAND_SZ values if you want references to other environment 
variables to be expanded, but keep in mind that these are evaluated 
in one pass for each category, and that local machine is evaluated 
before current user. A value can't make references to other variables 
in its own category, just references to values in other categories 
that are evaluated earlier.

. (apologies for the dot, but the web shows this group has failed 
to sync on my machine)

I'm hoping this a false reading, and my machine hasn't been infected/hijacked

I am actually writing this for use in my job. I am a network support/programmer 
and I work for Nuns. I have been connecting to their computers using 
VNC. I always have to try and tell them how to give me the address 
of their machine after I get them to start VNC. They always have 
trouble. So I thought I could write something in REBOL do they could 
just double click and read it clearly on the screen. That is why 
I mentioned the large font.

You have to boot from CD. Either connect a CD player to those machines 
temporarily, or take out the hard disk and do the installation on 
a different machine

If you're installing on a stand-alone machine, you could get away 
without configuring anything, and with a different partition setup 
you only have to modify the filesystem table, which is standard practice 
for Unix types

We created a bunch of virtual machine images, so you can try Syllable 
Server easily in an emulator without installing it:

I mean, on the server I just need a text interface and no GUI frills. 
Just lean and mean machine.

So now their sales pitch is: here is a unique machine with unique 
software that is good for your kids. It's open source, so it's superior. 
It's just that it's very slow, so you can also choose to boot it 
in this Windows thing. The special kid's environment and all the 
special driver software isn't there, but at least it isn't slow as 
molasses. Oh, we doubled the price of the machine, and to run this 
Windows thing you also have to buy and install this extra memory 
upgrade

Hm. A Syllable colleague says loosing time is basically through a 
heavily loaded machine

The format of the binary is just that: the format. Even if many systems 
use ELF these days, the machine code instructions you store in that 
format are still very different

The same goes for a static library (which would be called .a on most 
systems). There are still system dependent machine instructions in 
them

Running on the same CPU architecture with the same machine instructions 
is also just that. Those machine instructions call system functions, 
so you need to provide those on the target system

I also liked what I saw of Haiku.  


I do plan on trying out syllable in the not too distant future... 
basically when I'll build myself a linux machine, I'll make a few 
different boot partitions on that machine, one will be syllable  
:-)

ok, well I'll give it a good testing when I get that extra machine 
setup.

On a 192 MB machine, it starts up using 13 MB. On a 768 MB machine, 
it uses 21 MB for itself

Sorry, not yet. We've been working towards installing from and to 
USB sticks, but it's not complete yet. Syllable Desktop can install 
from a USB CD player with the regular install CD, so that's the normal 
way to install on a netbook or other machine without a built-in CD 
player

There are ways to do installations that are not possible in the above 
ways, but they are more complicated. You could start the install 
CD in a virtual machine after you have mounted a physical disk or 
partition in the VM, and install to that. Then afterwards, you'd 
have to configure the bootloader on the physical disk to start that 
installation

There are also other websites running on that machine. In general, 
Cheyenne makes them quite responsive. For example, it responds very 
well to a heavily loaded machine. You can fully load the machine 
with other tasks without noticing it in the responsiveness of the 
websites. In my mind, this is quite like the general behaviour of 
Syllable Desktop and earlier systems such as BeOS and Amiga

machine

I've tested Haiku. 1) It does not have pppoe out of the box, and 
afair on its forums there is an unfulfilled request for pppoe. 2) 
Haiku uses VESA mode on my machine, supports more modes than Syllable, 
and is MUCH MUCH faster re: windows dragging with mouse than Syllable. 
Haiku reports: VESA version = 3.0, capabilities 1. Haiku allows for 
1280x1024x32 mode while Syllable only allows 1280x800 mode and shows 
a black screen in 1280x1024 mode.

But I am scared a abit, as if Squirrel would be vulnerable, it sends 
mails from localhost, and then it would be really bad. Time to finally 
build new machine, install vmware ESXi, and some new distro upon 
that.

As far as I know, there is no USB module in JeOS. JeOS is designed 
to be run inside a Virtual Machine, not as a Virtual Machine Host.

Also, are you using wireless networking? I have a machine running 
Hardy and ended up needing ndiswrapper to get wireless working well. 
The following instructions worked for me: http://ubuntuforums.org/showthread.php?t=766560

I'm not using wireless on my main machine, but my wireless networking 
experiences in linux have been abysmal ones so far. I didn't devote 
myself to it, though.

Another option is dtach, which allows you to detach from and reattach 
to a terminal session even if you completely disconnect from the 
machine in the interim.

Petr, if you are writing your own video player, maybe you can do 
something, but don't expect it to be easy (well, maybe you can just 
stick to one specific version of the driver). Why do you want to 
do this? Isn't software playback good enough? 720p H264 works fine 
on this machine which is an old Athlon XP 2600+. Do you really need 
1080p? If so, isn't a cheap laptop MB able to give you that in software 
already?

try the package manager, it can usually tell you what has been modified. 
if it can't or that has been hacked as well, you need another machine 
with the exact same distro/version and check the md5s.

You can use screen to detach a session and reconnect with it later, 
possibly from an entirely different machine

At the danger of sounding repetitive, Syllable is one of the few 
systems you could reasonably try on such a low-memory machine - especially 
for an Amiga enthusiast

I post a message to Carl on R3 when I'm back at the Linux machine.

you may be able to create your own live cd that does what you need 
but... i think that's more work than installing, or using a virtual 
machine.

its actually about 15 minutes to download install and run on any 
server (or your machine).  and from there, rebol cgi is much faster 
since its persistent.

When I use: ssh -L 44000:192.168.22.1:44000 [user-:-my_vm_server-:-com], 
from a remote machine, the SSH tunnel is setup and the login is done 
on my_vm_server.com

When I use telnet localhost 44000 from the remote machine, which 
should tunnel through the SSH channel and forward to 192.168.22.1:44000 
on my_vm_server.com, I get a connection but the listen server doesn't 
recognize it...

Thanks Petr. He may have to wait for a supported UNICODE-enabled 
release.


Having given it a few moments thought, he may be able to fake it 
in *some* controls with font-name:

    view layout [box "hello" font-name "xxx"]  ;; where xxx is the name 
    of an installed font on his machine.

I tried that with my ASCII chart script, making that change. And 
it does (for me) show some Cyrillic. Not sure it's a complete solution 
though:
   http://www.rebol.org/view-script.r?script=ascii-chart.r

It works like this:
1) Write some 6502 asm in the text area. Example:
lda #&80

2) Press the button "Assemble". Now you can see the opcodes in the 
ram at address 0000.

3) Press the button "Begin" to run the emulator with the produced 
machine code and see the results in the registers and flags.

not news, but this is like science fiction made true !!!  http://en.wikipedia.org/wiki/Z_machine

Taken from OSNews - so much for a "great" Apple:


Parallels recently made a definitive statement saying that the company 
won't be making it easy for users to run OS X in a virtual environment 
anytime soon. The reasoning behind this was because they don't want 
to put their users at risk of breaking the OS X EULA - unlike Windows 
Vista, there is no version of OS X that can be run under a virtual 
machine - and more importantly, they don't want to strain their (currently 
good) relationship with Apple. As a followup to that statement from 
Parallels, I was able to also get in touch with Srinivas Krishnamurti, 
VMWare's Director of Product Management and Market Development in 
order to get VMWare's official position on the matter. 

Apple does not currently allow running Mac OS X in a virtual machine," 
he said. "Apple is an important partner and VMware respects Apple's 
intellectual property."

is this slow because it's tattoo machine or it's slow because of 
the Silverlight itself? http://silverlight.net/samples/1.0/Ink-Tattoo-Studio/default.html

Very cute..................a lot like my P7010.  Will be a great 
machine for Qtask...

Yeah, let's teach people how to start the ocean on fire.  Luckily 
it's not even close to break even on energy.  I read his machine 
was using about 10 times more joules than was coming out of the burn.

People seem to believe that there is talk about a perpetual motion 
machine, which of course isn't true. Same with the water fuel cell, 
which has a strange and sad story, but seems to be moving forward 
now.

http://unicap-imaging.org/unicap_eeepc.htm<--- this looks like a 
nice and interesting machine.

Kaj;  Some of the articles mention that Everex tried with a sub $400 
Vista machine.  (Same hardware, but with Windows license fees bumping 
the price).  Too many returns...which is where I think the "low-end 
PC market" quote originated.

I think he refers to autonomous machines, rather than just any machine 
that resembles a human or an animal :) http://en.wiktionary.org/wiki/robot

Nevertheless you have scrap out there and the chances are high with 
real no-names. But this comes from a lot of them think, some products 
are easy to manufactor. But this is not the case. Building a real 
good washing machine like a Miele is everything than simple. Even 
if you disassemble the machine you are not able to clone it.

V8 virtual machine ...

google Chromettechnologie us the a process design and a new javascrip 
(V8) virtual machine with some cool features like powerfull object 
based garbage collection and  auto object creation (even if you don't 
say so your javascript is decompose into objects) each tab is a separate 
process each things that are needed to show a page is rendered simultanously. 
no asynchronous system so

At least if I hang up on a machine, I won't feel I'm being rude :-) 
Hopefully it speaks clearer than most of the indian call center operators. 
On the serious side I am looking forward to seeing where the tech 
will lead us.

Volker - but doesn't opening port work on one machine only? Still 
semaphore file is probably better way to go, at least under Windows, 
where it does not let you to delete file, when it is opened by some 
other task .....

Yes, works on one machine only. I think that is the usual case for 
small accounts. If you are bigger, you should use a daemon to sequence 
access IMHO.

and a new PC. that stupid machine just died. glorious day today.

liquid state of affairs:

-GLASS v1 is going through intense development.

-GLUE - foundation plugs,  although not yet released is getting packed 
with fully documented plugs weekly.  there is more documentation 
text than actual code in the lib!

   (optimised in how they prevent useless processing and messaging).

After rebooting my OSX machine, Cheyenne doesn't work anymore. I 
didn't change anything. It starts and runs and launches its task 
handlers, but there is no access from a webbrowser. Does it create 
some kind of start up log so I can tell what's wrong?

Although it is possible to take advantage of multi-core technology 
by running several applications processes in parallel, the real benefit 
would be for multi-threaded applications. The challenge then is to 
change single-threaded or sparsely threaded applications into multi-threaded 
and also to debug them.

Erlang has unique properties for taking 
advantage of multi-core technology
One of the fundamental properties 
of the Erlang language is built-in support for very light-weight 
processes, each with its own memory, and using explicit message passing 
for their communication. Because of this most applications written 
in Erlang are realized as a number of cooperating Erlang processes 
representing something in the problem domain of the application, 
for example active call sessions, connections or transactions. Typically 
this will result in many thousands of simultaneously executing processes 
in a heavily loaded application.

The parallelism already present 
in most Erlang applications makes them ideal for taking advantage 
of multi-core technology, without there being any need to modify 
them.

The only thing needed is an Erlang virtual machine (VM) which 
works in a multi-threaded way, and that is what we now are releasing 
in Erlang/OTP R11B.

DocKimbel, small request: Would it be possible to post the rsp guide, 
cheatsheet and docs as separate pages directly on the site? It's 
unpractical to have to download Cheyenne every time I switch machine, 
just to read the docs. Thanks.

yes, actually I was reading thru slashdot when I saw an article pointing 
to our server running Cheyenne, only then I went to look how that 
machine was doing (xserve 2x2.2GHz G5), I saw a little more cpu usage 
and  about 80 rsp requests/sec . I'd say rock solid! Go Dock Go (like 
Brian Tiffin like to say)  8-)

But scripts work on 8080? Are you testing on the local machine or 
via network?

Multiple running instances :


1 ) Cheyenne uses a port translation method for task-master to avoid 
clashing between Cheyenne's instances. This translation is currently 
triggered by the -p command line option specifying on which port(s) 
Cheyenne should listen. So the 'listen keyword in config file doesn't 
trigger the translation. After a quick look, it should be fixable.


2) Logger and RConsole services ports are not translated. This should 
be fixed too.


3) As a consequence of 1) & 2), Cheyenne can't currently run multiple 
instances on the same machine.


I am running two instances because the web app uses the same database 
name
 :


4) I very well aware of this issue and I intend to find a solution 
asap.

OpenSCManager failed : Access is denied

5) I should load that routine! only if trying to run as a Windows

It works fine. I only use IE for testing and Qtask - everything else 
I use Chrome. I know how to make a Windows machine stable :)
