Serious danger of being impressed

ruby-talk

I'm mostly into Python, and decided to have a go at writing a little accounts package (in python on OS X). It worked in its primitive way, and I was looking to take it to the next level.

I decided that sqlite was the way to go. For some reason I couldn't get sqlite3 and the python module to work properly - it didn't seem to commit the data to the database consistently.

So I thought, what the hell, I'll try Ruby. I switched over to Ubuntu, because it seemed a bit easier than OS X. First impressions: oh man! The sqlite package worked fine, and I came across rsqlitegui, which I can use to inspect the database when coding isn't required.

I think Ruby is a serious serious contender for python.

I'm also in two minds as to whether I should try to switch over from OS X permanently. I'm new to iMacs, and I have to say that OS X has a nice polish to it; but then Ubuntu, gotta love those repositories.

There's a few sore spots on the Mac, but I find MacPorts does the
trick most
of the time.

port install ruby rb-rubygems rb-sqlite3

That should do the trick as long as you don't mind the /opt/lib file
structure.

I always modify my ~/.profile as well to include:

export RUBYLIB="/opt/local/lib/ruby/site_ruby/1.8/"
export RUBYOPT="rubygems"

I just don't like having to manually require 'ruby_gems' :wink:

Sure it's not perfect, but MacPorts means I've never had to think
twice about the notoriously difficult RMagick install:

port install rb-rmagick

It's no apt-get, but I'll leave that to the servers. Trade in OS X for
Ubuntu? For me that'd be tough. Kubuntu maybe. :wink: Kate is second only
to TextMate IMO.

Either way you decide to go, good luck!

    As a language, Ruby has always been "a serious contender" for Python.
Personally, I like it a lot more than Python.
    The main advantage of Python over Ruby is a larger library and (more
importantly, since there is a rich library for Ruby) a much more mature
implementation. Sadly, Python is, really, just as powerful a language as
Ruby, so this gives people every reason to use Python over Ruby, so it would
help Ruby to work on these things...
    What is the state of Ruby development, does anyone know? The impression
that I get is that it's slow and diluted across multiple, parallel
efforts...

If you like Ubuntu's repositories, you should check out Debian's -- much
more extensive, and generally conducive to a more stable system, too.

Similar in extensiveness is FreeBSD's ports collection -- and even *more*
conducive to stability than Debian's repositories. That's hard to beat.

Both Debian and FreeBSD tend to work best for people who are willing and
able to make their own decisions, however, more than people who want
something "easy". Ubuntu is far more suited to the average MS Windows
transplant, I suppose.

The above is just one curmudgeonly free unix hacker's opinion, of course.

Do bear in mind that it's pretty easy to use /both/ on modern Macs. Linux
has a lot going for it from a development point of view, and most of the
documentation out there (not to mention most of the packages) is aimed at
Linux-based builds. OS X is great as the day to day desktop, though.. so a
lot of people use both. You can use Parallels or VMWare Fusion (the latter
currently being free and faster) and live in the utopia of a great desktop
but with a well-supported and popular cross-platform architecture on tap for
development purposes.

And Gentoo Linux is a good compromise between FreeBSD's ports and
Debian's repositories. Gentoo's Portage actually descended from ports.

As far as stability is concerned, Debian stable (currently called Etch)
is probably as stable as FreeBSD and I think *more* stable than Red Hat
Enterprise or the RHEL clones.

But I will stick with Gentoo for Ruby. Except when the Gentoo devs don't
get prodded from the Ruby community, a Ruby release shows up in Portage
within a day or so. They have jRuby 1.0 RC1 the last time I synced,
which was yesterday, for example. And they have more gems than Debian, I
think.

I must admit that since swapping to FreeBSD last year I find using most Linux distros unnecessarily cumbersome and increasingly user friendly in the same way as Windows. But OS X is also a damn pleasant platform to use and I probably do more of my Ruby development work on it than I do on FreeBSD - TextMate alone makes it hugely productive!
Ubuntu would be the platform that I'd recommend to a Windows user looking to get into Linux as a user, and Gentoo if they really want to deep geek how a Linux system hangs together :slight_smile:

Ubuntu’s based on Debian unstable, so the repositories should more
or less match. Also, while I consider Debian stable more stable than
Ubuntu, I consider Ubuntu stable more stable than Debian unstable. :slight_smile:

And they [Gentoo] have more gems than Debian, I think.

That said, Debian (and, thus, Ubuntu) has the rubygems package, which
can easily install any gem (to /var/lib/gems, so outside dpkg’s domain).

Note: A quick check at packages.gentoo.org indicates that Gentoo
has a rubygems package as well, so this might be a moot point.

Really? Like as in, Linux descended from Unix? Or in some direct fashion? I

The paludis devs are currently working on direct support for gems
repositories. Once this is complete we will have direct support for all gems,
without having to wait for them to become ebuilds (not that writing an ebuild
for a gem isn't trivial...)

Very cool...

Ubuntu is a Debian *fork*. It has less in common with Debian itself than
PC-BSD and DesktopBSD have in common with FreeBSD, and may even have less
in common with Debian than Dragonfly BSD has with FreeBSD.

In fact, measured within the context of Linux distributions, about the
only thing it meaningfully has in common with Debian is the
under-the-hood package management software it uses (namely, DPKG and
APT).

Well, as long as we're talking virtualization, has anyone managed to get
a Xen system on one of the chips with the virtualization assist to run
OS X as a "guest?" Or does Xen not support the special hardware tweaks
in a Mac? Dual or triple booting is a pain.

Is there virtualization in openSolaris? Will it run a Windows or MacOS

Ubuntu is a Debian *fork*.

More true in theory than in practice. There was a lot more noise
about the fear that Ubuntu would be a fork back in 2005 when Debian
users were getting tired of waiting for Sarge and Ubuntu started to
appear on the horizon.

But the truth is, at least, more nuanced. And even guys like Ian
Murdoch pointed that out at the time:

http://ianmurdock.com/?p=167

And for a view from the Ubuntu "camp" at that time:
http://mako.cc/writing/to_fork_or_not_to_fork.html

Ubuntu takes packages from sid, stabilizes them before debian, but
feeds whatever changes they make back to the sid stream.

So it provides a stream of debian derived releases but instead of
using the traditional Debian model of "we'll ship the next stable
version when it's ready," Ubuntu has a time-box ship model. Ubuntu
makes the final decision on what's going to actually make the next
release based on which packages have achieved stability in time to
make it, instead of waiting until all of the packages which were
picked at the time the release was started get there. One way of
looking at this is that Debian has a more waterfall release cycle
while Ubuntu is managed using more of the agile project management
approach. Back when Ubuntu "Badger" was in the throes of being
released, Debian Woody was several years old, and Sarge looked to be
slipping almost faster than the release date was approaching,
something which Murdock alludes to in the post I quoted.

The tension is/was? between the needs of server administrators who
favor a stable platform with security maintainence, and developers who
want more recent versions of the upstream code. Back then Ubuntu was
better for the latter. Then they introduced 'long term support'
releases which are specific Ubuntu releases which will have committed
support for five years (or there abouts). This helps the server
users, since the downside of Debian's support policy is that they only
provided maintenance for an older stable release for a limited time
after a new stable release becomes available. The net is that Ubuntu
provides both newer code in the latest release for those who want it,
and more predictable support of older releases for those who need
stability.

It has less in common with Debian itself than
PC-BSD and DesktopBSD have in common with FreeBSD, and may even have less
in common with Debian than Dragonfly BSD has with FreeBSD.

I don't know enough about those distributions to make the comparison,
but from my experience, Ubuntu doesn't feel like a fork. Even if
Debian doesn't take ALL of ubuntu's packages as time goes on, I
predict that the bulk of the code will remain compatible.

That all said, while I'm a happy Ubuntu user, I don't use packaged
versions of some specific software, most notably Ruby. This isn't
because of Ubuntu but because of Debian. In the case of Ruby one
major reason is because, as far as I know unless it's changed
recently, Debian (and therefore Ubuntu) doesn't really support gems.
Now this may have changed recently, but I've been happy installing
Ruby and Gems from source, and gems as gems.

Last time I looked at it there was some weird philosophy for not
having gems support in apt. If I remember correctly it was because
gem uses a folder per package type deal and that goes against the
grain of apt. I can't find where I read this, so you'd need to do
lots of googling to find it.

Uhh . . . what? I said it was a fork. I didn't say it was crap. I'm
not sure where you're coming from with the hostile tone.

From http://en.wikipedia.org/wiki/Fork_(software_development):

  In software engineering, a project fork happens when developers take a
  copy of source code from one software package and start independent
  development on it, creating a distinct piece of software.

From http://wiki.ursine.ca/Fork:

  In the open-source community, a fork is what occurs when two (or more)
  versions of a software package's source code are being developed in
  parallel which once shared a common code base, and these multiple
  versions of the source code have irreconcilable differences between
  them.

(Note: The commentary about Linux distribution forking in the Jargon Wiki
is somewhat naive, in terms of its assumptions about the differences
between Linux distributions. The key component of forking is
incompatibility, not whether or not something is composed primarily of
widely available elements.)

So . . . why does your statement read as though you thought I said
"Ubuntu is a *crappy Debian fork*!"? I said nothing of the kind in my
statement as quoted by you. I pointed out that Ubuntu and Debian are not
compatible -- are not, in fact, simply different implementations of the
same standard, as the previous message seemed to imply.

about the fear that Ubuntu would be a fork back in 2005 when Debian
users were getting tired of waiting for Sarge and Ubuntu started to

If you cannot install a Debian package in Ubuntu, or vice versa, without
running substantial risk of breaking the system, it sounds like a fork to
me.

But the truth is, at least, more nuanced. And even guys like Ian
Murdoch pointed that out at the time:

http://ianmurdock.com/?p=167

And for a view from the Ubuntu "camp" at that time:
To Fork or Not To Fork: Lessons From Ubuntu and Debian :: Benjamin Mako Hill

Ubuntu takes packages from sid, stabilizes them before debian, but
feeds whatever changes they make back to the sid stream.

In Ubuntu releases, there's a lot more changed. A simple look at some of
the software dependencies enforced by APT in Ubuntu, as contrasted with
those in vanilla Debian, will make that clear.

So it provides a stream of debian derived releases but instead of
using the traditional Debian model of "we'll ship the next stable
version when it's ready," Ubuntu has a time-box ship model. Ubuntu
makes the final decision on what's going to actually make the next
release based on which packages have achieved stability in time to
make it, instead of waiting until all of the packages which were
picked at the time the release was started get there. One way of
looking at this is that Debian has a more waterfall release cycle

approach. Back when Ubuntu "Badger" was in the throes of being
released, Debian Woody was several years old, and Sarge looked to be
slipping almost faster than the release date was approaching,
something which Murdock alludes to in the post I quoted.

I really don't think the waterfall vs. agile analogy holds even slightly
true. Both Ubuntu and Debian strive to produce "complete" distribution
releases with each release cycle. Debian maintains a constant state of
operational functionality during development of the finished release
(thus the "testing" branch), and Ubuntu (from what I've seen) provides a
more "there's nothing to see until it's done" state of development until
it approaches release-worthiness. Neither of these sounds anything like
either Waterfall or Agile development to me. In Waterfall development,
nothing's functional until you're done, and you're not done until you've
achieved some overarching plan. In Agile development, you have
functional milestones, but you're not really done until you've achieved
some overarching plan (though, of course, the plan changes while being
executed).

The tension is/was? between the needs of server administrators who
favor a stable platform with security maintainence, and developers who
want more recent versions of the upstream code. Back then Ubuntu was
better for the latter. Then they introduced 'long term support'
releases which are specific Ubuntu releases which will have committed

It's pretty clear that the unfortunate comparison of Debian to Waterfall
development was no accident. You have a definite Ubuntu bias.

Code: yes. Packaging: no. Since Linux distributions are defined by
their software management systems and installers more than by the source
code inside the various pieces of software, that pretty much makes Ubuntu
a fork (though a still-recent one that attempts to derive some benefit
from similarities between the two distributions).

That all said, while I'm a happy Ubuntu user, I don't use packaged
versions of some specific software, most notably Ruby. This isn't
because of Ubuntu but because of Debian. In the case of Ruby one
major reason is because, as far as I know unless it's changed
recently, Debian (and therefore Ubuntu) doesn't really support gems.
Now this may have changed recently, but I've been happy installing
Ruby and Gems from source, and gems as gems.

Whether or not Ubuntu supports gems is not dependent upon whether or not
Debian does so. It's dependent upon Ubuntu management decisions. The
Ruby packages have already diverged nontrivially from those in Debian
(though obviously not as much so as certain other packages).

Uh, Debian does run gem and gems just fine.
Shared hosting provider DreamHost is proof of that.
Their servers are Debian, and they do have gems. I've installed my own local gems on an account there.

More true in theory than in practice. There was a lot more noise
about the fear that Ubuntu would be a fork back in 2005 when Debian
users were getting tired of waiting for Sarge and Ubuntu started to
appear on the horizon.

But the truth is, at least, more nuanced. And even guys like Ian
Murdoch pointed that out at the time:

http://ianmurdock.com/?p=167

And for a view from the Ubuntu "camp" at that time:
To Fork or Not To Fork: Lessons From Ubuntu and Debian :: Benjamin Mako Hill

Ubuntu takes packages from sid, stabilizes them before debian, but
feeds whatever changes they make back to the sid stream.

So it provides a stream of debian derived releases but instead of
using the traditional Debian model of "we'll ship the next stable
version when it's ready," Ubuntu has a time-box ship model. Ubuntu
makes the final decision on what's going to actually make the next
release based on which packages have achieved stability in time to
make it, instead of waiting until all of the packages which were
picked at the time the release was started get there. One way of
looking at this is that Debian has a more waterfall release cycle
while Ubuntu is managed using more of the agile project management
approach. Back when Ubuntu "Badger" was in the throes of being
released, Debian Woody was several years old, and Sarge looked to be
slipping almost faster than the release date was approaching,
something which Murdock alludes to in the post I quoted.

The tension is/was? between the needs of server administrators who
favor a stable platform with security maintainence, and developers who
want more recent versions of the upstream code. Back then Ubuntu was
better for the latter. Then they introduced 'long term support'
releases which are specific Ubuntu releases which will have committed
support for five years (or there abouts). This helps the server
users, since the downside of Debian's support policy is that they only
provided maintenance for an older stable release for a limited time
after a new stable release becomes available. The net is that Ubuntu
provides both newer code in the latest release for those who want it,
and more predictable support of older releases for those who need
stability.

It has less in common with Debian itself than
PC-BSD and DesktopBSD have in common with FreeBSD, and may even have less
in common with Debian than Dragonfly BSD has with FreeBSD.

I don't know enough about those distributions to make the comparison,
but from my experience, Ubuntu doesn't feel like a fork. Even if
Debian doesn't take ALL of ubuntu's packages as time goes on, I
predict that the bulk of the code will remain compatible.

That all said, while I'm a happy Ubuntu user, I don't use packaged
versions of some specific software, most notably Ruby. This isn't
because of Ubuntu but because of Debian. In the case of Ruby one
