Glad you guys liked it. And, I did not notice that typo until you
pointed it out - will fix.
Thanks,

I totally agree, the presentation is VERY COOL!Great visual style, great accent on the details in small steps, great topics covered, no clutter. The only minor criticism is the use of the word "breath" instead of "width". If it wasn't some intentional joke, I would at least fix the typo in "brea_d_
P.S., this is fun to show off too, also implemented as a library.
USING: infix ;
INFIX:: quadratic-root ( a b c -- x )
(-b+sqrt(sq(b)-(4*a*c)))/(2*a) ;
It's a little fragile though, I just noticed it doesn't seem to let me
output more than one value on the stack (-b +/- sqrt...)
This is GREAT!
I love the topics covered, the step-through approach, and the overall
feeling. I bet that was a great presentation.
Best,
John.

Hello Everyone,
Thank you for your inputs. In the end, I decided to focus on the aspects
of Factor that I was most amazed by when I first discovered the language
last year. I presented yesterday, and it was received well. I think I
kindled the interest of a few people who attended.

You see? It could use some limelight! : ) Also, thanks for pointing out the `tools.memory` vocab. Not only will it provide some insight for me as to the memory use pattern for my DB-heavy apps, but also it uses some juicy words like `object-table.` Too bad those aren't documented, I might have disc
Well, it looks like we have this more or less exact word in
``tools.memory:commas``, and something very close in ``money:format-money``.

Hello! Wow, this is way more general than what I came up with: ```: num>grouped-str ( n -- str ) number>string 3 "," join reverse ;``` Maybe your code should be included in the prettyprinter or somewhere similar, next to `number>string`, perhaps? 17.06.2017, 02:33, "John Benediktsson" :Note: t
Note: that word doesn't work properly for negative numbers. This is better:

[ reverse 3 "," join reverse ] dip

We don't have that kind of locale support right now, but you could use
something like:
: number>string-with-commas ( str -- str' )
number>string "." split1
[ reverse 3 "," join reverse ] dip
[ "." glue ] when* ;

Hello!
Is there a standard way to output a number with comma separators grouping the
thousands?
```
1,000,000 num>str-grouped
"1,000,000"
```

You could look into vm/errors.cpp and see which is the lowest level error
that you want to catch (``fatal_error`` maybe)?
Your code would probably not be cross platform so you might need to add a
hook you can implement on Windows. Perhaps change/use the ``abort()`` API.

The VM has low level primitives:
void load_image(vm_parameters* p);
bool save_image(const vm_char* saving_filename, const vm_char*
filename);
I'm not sure if better to put it there or in the Factor code, but probably
there because it gets called as part of the VM startup to load an image
Hello!
I'd like to make Factor show a native MsgBox on any uncaught exception on
Windows.
For example, currently if you run without a console, you won't see the "Out
of memory" message.
I'd like to change that.
Where should I look for the code that could handle that?
Do you think it wo
Hello!
I'd like to be able to sign the factor image and verify the signature on
startup.
Wouldn't that be cool?
Did anyone think in that direction?
