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.

Great news! Does a book centered only on Factor exist yet? I remember
reading that someone (possibly John Benediktsson?) had started one,
but I do not find a link anymore

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
Thank you for the explanation! It is nice to see that Factor does

Node applications

Hi, I am trying to implement monoids in factor. A monoid is a set with
a binary associative operation (and, depending on the defintiion, a
neutral element for it).
Typical examples are numbers (with either addition or multiplication)
or sequences (with concatenation). Other examples can be

Hi, following this [small

It is inspired by [Metacello](https://code.google.com/p/metacello/)
but delegates to existing source control management software such as

simple that encourages re-use of code is pretty great, we
could probably share our testing infrastructure to support easy continuous

More to come later when I have time.

Factor needs a package management system eventually. Programmers have

I took the freedom to stub a package manager because for me it was one

Hi, I was preparing a talk about Factor, and I recall having seen
mentioned on this list two things that might turn out useful for the
presentation. Unfortunately, I cannot find them anymore.
1) I remember someone mentioned a tool that would show the speculative
status of the stack in realtime
Great, set-listener-font is exactly what I needed!
About 1, I was meaning something different. It was an experimental UI
gadget that would show the (speculative) status of the stack while the
user keeps entering words. Or maybe my memory is at fault

By the way, I do not think it is a good idea to directly parse or
format numbers based on locale, for portability.
I would rather have different functions that also take a locale into
account (not necessarily the system one) and a constant with the
system locale
