Hello,
I'm one of the active people in #python that some people dislike for
behavior with respect to Python 3.
First of all I'd like to defuse the situation, much like Jacob.
Seriously. It's been a bunch of posts so far and most of them have
been pretty angry. Let's take a deep breath and try to fix the
situation that's getting people frustrated like grownups :-) (FWIW: I
find being called worse than half-intelligent pretty offensive. Let's
stop doing that?)
The idea being expressed in the IRC topic is _way_ bigger than the
room an IRC topic gives you.
Hey Laurens - I don't have an issue with with anything you've said,
but given the topic is far more nuanced than an IRC topic can express
maybe that just isn't the right place for it.

Yes, it's an imperfect medium, yes, it's
probably partially based on the use case: it's just that experience
leads us to believe that the vast majority of use cases ends up being
more in 2.x turf then 3.x turf, at the very least in the past.
I'm sorry if you had the impression people wanted to nail you at the
stake for using Python 3. If that's how you felt, it isn't true. I
basically agree with Glyph. I don't think we've recently (I'm not
omnipresent) told anyone who had any good reasons to to stop using
Python 3. If someone's doing work that actually needs Python 3 (most
recent example a GSOC student porting Sphinx), we try our best to
help, and AFAICT we've mostly been successful. (Please correct me if
you think this is erroneous.). We don't get too many people that
actually want or need that, but I'm guessing that's mostly because
people porting libraries to py3k usually already know what they're
doing so they don't need the first-line-of-defense thing for Python
questions that #python tries to be.
Maybe you disagree on what good reasons are. #python is a bunch of
volunteers giving help, free of charge, which is usually of a pretty
high standard because they're professional Python developers and have
been for a long time. Maybe that biases some of us against Py3k? Fact
remains that there's a bunch of active people on IRC who pour a lot of
time and effort into #python and make a lot of newbies really happy,
and I think the picture you're painting based on a single issue that
clearly not everyone agrees on is a bit disrespectful and somewhat
unfair.
Also, I'm pretty sure nobody has ever said that Python 3.x was a
"failure", or anything like it. #python has claims that Python 3.x, as
a platform for building production apps, is a work in progress because
of third party library support, and the language itself is pretty much
done and okay -- a cleaner version of 2.x. People ask why it's too
early to use Py3k, and that's _always_ the answer they get: at least
the first half, and usually the second half too.
In the mean while, we encourage people to write code that will be easy
to port and behave well in 3.x: new-style classes, don't use eager
versions when the Py3k default is lazy and you don't actually need the
eager thing, use as many third party libraries as possible (the idea
being that this would minimize effort needed to make the switch on the
grand scale of things), use absolute imports always (and only explicit
relative, but it's discouraged), always have a full unit test suite.
This is advice that generally makes a lot of sense, and it's the
recommended thing in PEP 3000 for porting to 3.x as well.
We're still telling people to use Python 2.x by default because of a
few major things:
1. going out on a limb here: well over 90% of those people are
completely new to Python and out of those most of them completely new
to programming too,
2. the nicest libraries for doing a lot of stuff aren't ported yet, or
are in the process of being ported but not yet recommended for actual
use by their authors, (this seems to be a point of contention?)
3. we know how to help people better with it
Which are all basically different incarnations of the same issue.
People are working on libraries everywhere and I really don't want to
pretend those people haven't gotten any work done, but AFAICT a lot of
these for existing mature projects that you'd want people to use in
order to be happy productive Python users don't really exist yet or
are at best experimental. At the very least I think most people can
agree that 2.x is still the default release for existing, mature
software projects and most new ones too.
I can only speak for my own area of intrest: Python is way too big for
anyone to have used every piece of software for it ever. I,
personally, don't use 3.x because I develop for PyS60 devices,
PythonCE devices (2.5 only), and Twisted servers (2.6), and none of
those work on 3.x yet. The other thing we build is websites, and AFAIK
the web situation, for now, is still "use python2.x", too? (for any
non-trivial website, of course). We use AMQP, and the best thing we've
found for it is 2.x only (maybe Carrot and Pika do 3.x now, but I
can't find any evidence of it). Nobody here (here = place of business)
hates Python 3. We just can't use it.
I'm very sorry if you've been offended. Like Glyph said: we're not
grinding ideological axes. We're just recommending what we honestly
believe is the right tool for the job. We're just humans, we're not
perfect. We make mistakes. If you feel we've made them, please just
tell us and don't start a war. If you tried and failed, please feel
free to tell me how (doesn't have to be in public) and why it failed,
and maybe I (or someone else!) can try to fix it: that's *not* how
stuff is supposed to happen. Maybe someone was being a troll, I
haven't checked but I trust the people I run #python with enough to
say that it probably wasn't a regular. That's IRC for you: the problem
is that if you let everyone speak once in a while trolls open their
mouths. Perhaps something someone said was just taken too seriously. I
don't know the situation you're referring to, I just know #python.
Again, just because someone asked and nobody removed that line ('It's
too early...') doesn't mean we're evil pricks that want people to use
Python2.x because of some hidden agenda. It just means that person
disagrees with the idea that it's a good time to start doing it. IRC
can be a harsh place, not because the people are jerks but because the
medium just lends itself to it. People are generally a not nicer than
they appear.
Like Nick said: not too long ago this was perfectly sound advice. I'm
convinced it still is; maybe I've (and a lot of people active on
#python) been out of touch with recent evolutions and it's no longer
true. I don't know. I'm just a bit sad that it had to come angry
ventings (no grudges, I realise most of it is probably just
frustration). I like to think I'm not wrong when I think that if
people just ask "Hey, guys, this Python 3.x rule, don't you think it's
about time we reviewed that? It's been up for a long while." people
would get banned or anything. Maybe people disagree and think it
should still be up there: but at least we could have a productive
discussion hopefully resulting in something that makes everyone happy
or at the very least less frustrated. I just asked a two regulars and
despite the fact that we're about as widespread as we possibly could
timezone wise (SE Asia; Western Europe; WA, USA) nobody remembers that
happening.
Also, on tiwsted Twisted: yes, #python is very Twisted-minded, we have
a bunch of people that like it, develop it, have built cool software
with it and we think it could help other people too. It's not
ideological axe grinding: a lot of the regulars just genuinely like
Twisted. I'm sorry if you felt that not liking Twisted was going to
get you smacked across the face, but that's not true either: Ronny
Pfannschmidt is a regular, and he really doesn't like Twisted. We just
think that for a lot of questions people come in with, Twisted is a
great solution. That doesn't mean you're not allowed to have contrary
opinions or that all dissent is crushed with an iron fist: it just
means that the people who actually bother to help others day in day
out know Twisted, like Twisted, and think Twisted is a great tool for
a lot of problems. If you don't like Twisted, feel free to use
something else: just don't complain when nobody can help you because
the people offering help are all Twisted users that don't understand
your software and don't have time or incentive to. It's a purely
pragmatic thing. There's no hidden agenda.
I've put bits of this up for review to #python regulars, so when I say
'we' it usually does mean 'we, #python regulars'. Most of it
resonates. Maybe we're just in the distortion field?
thanks for listening,
Laurens
