I have tried, without chance, to run factor on Ubuntu 15.04 (and I
will move to 15.10 soon).
The 0.97 version fails with

I would rather have different functions that also take a locale into
account (not necessarily the system one) and a constant with the

mentioned on this list two things that might turn out useful for the
presentation. Unfortunately, I cannot find them anymore.

Hi,
I will be giving an introductory talk about Factor at the LambdaCon in
Bologna (Italy)
http://www.lambdacon.org/
Of course, I a not a Factor expert in any way, but I will make it
clear and try to show the potentialities of Factor. I was thinking of
following more or less parts of my tutorial
. At the same time, I would like
very much to help if I can.
I took the freedom to stub a package manager because for me it was one
of the main issue in really adopting Factor, but others may feel
otherwise

This version is slightly changed from the old one, but the basics are the same.
I think now I will let it rest until some more experienced factorers
(is this the right word?) decide if it can have any use.

Hi, I am trying to implement monoids in factor. A monoid is a set with

I am trying to interface with C code. Everything seems to work more or
less fine, until I have to deal with output parameters, that is,
parameters in C functions which are meant to be passed buffers which
are filled by the function.
I have made a very basic example which only copies a string and I

Hello,
I have written a Factor tutorial, which you can find at

It works for me too. Any chance this fix will be deployed in the
official download? It is unforunate that the default download does not
work out of the box on recent Ubuntus, as it may hinder adoption

I would be glad to see a 1.0 release, if anything just for
psychological reasons when I show Factor to my colleagues :-)

Hi, I have read in various places, including this mailing list, that
Factor does not currently have support for (preemptive, kernel-level)
multithreading, and that adding support for that would require a great
deal of changes, since the underlying VM and many core words are not
thread-safe.

Hi, I am relatively new to Factor, and I am trying understand how to
debug programs in it.
Whenever I make an error, a popup suggests to Traceback and open the
debugger. Now, I am used to the debugger in, say, Smalltalk, where I
can browse the current local variables, step into code, edit

I am trying to figure what is the Factor model to work with server applications.
If I understand correctly, Factor is single threaded, but the
underlying I/O facilities are not (I remember reading an article where
it was compared to Java NIO).
This resembles the model of Node applications: the ap

Hi all,
I am new to Factor and I am just starting to dablle with it. I have to
say that I am impressed that such a small community created a
programming language this mature and all the libraries that surround
it.
I am trying to figure out the current situtation about multithreading.
