[BLUG] *Free "Art of Community" Book*

Hello, all!

As one of the Indiana LoCo's Local Contacts, I've received some news
that could be really cool and interesting for some of you:

Jono Bacon, Ubuntu's Community Manager and probable holder of a
Guiness record for the most uses of the word "community" in a single
sentence, has written a book on managing them for O'Reilly. I don't
know of anyone in the free world more qualified to do so.

He also got the publisher to license it under a CC-BY-SA-NC license
which means we all have access to his work for free!

It is available for online perusal at
<http://my.safaribooksonline.com/9780596805357>, or see below for a
PDF link.

If you prefer a text copy, O'Reilly of course sells them for about $40.

I've include a couple of local LUG lists on this announcement, as
well, as I know the book is not intended to be Ubuntu-specific, or
even Ubuntu-centric. It's not even meant to be about computer, or
technical communities. It's about communities in general; from LoCos
to knitting circles.

I hope this finds you all having a wonderful day!

[BLUG] K-12 Open Minds - Open Source in Education Conference

Hello, all,

I'm publishing this announcement on several mailing lists I
participate in where I feel other list members might reasonably be
expected to be interested. Please forgive the spamming nature of this
e-mail.

This year's K-12 Open Minds conference, addressing the use of Free and
Open Source software in educational settings, has been announced and
there are quite a few changes from last year.

First of all, this year it's free! That's right, no fees to go.

Relatedly, it will no longer be held at a fancy hotel in downtown
Indianapolis. This year, it'll be at an actual school, in Northwest
Indiana, that uses Ubuntu Linux in their classrooms.

More details can be found at:

http://k12openminds.org/news/2009/08/24/announcing-k-12-open-minds-2009-now-open-and-free

Thank you very much for time. I hope this finds you all having an awesome day!

The bad idea, as I see it, is precisely that: a business plan that
involves a net subtraction from the amount of trees (not so much in
units, but in photosynthetic capacity) on the planet during a time
when they're already dropping at unacceptable rates.

If you're going out and cutting more trees than you're growing, or
getting rid of the few truly old trees we have left, I can't really
see that as a Good Thing. Even if you justify it as carbon
sequestration; it's the *growing* that's sequestering, and not the
chopping, if I understand things correctly.

If you start planting trees now with an eye towards a sustainable
cutting plan when they're at the appropriate size, I could maybe see
that; though that sounds too far from immediate gratification to be a
popular plan.

The operation you described sounds basically net zero, if they mow
only what they plant.

I just, you know, wanna keep being able to breathe long enough to
solve the carbon issue, ;-), so any plan right now involving less
trees sounds counter-productive.

There are many questions, f'rinstance:

How many poets & playwrights *are* eating, while still working full
time on their writings, right now?

How would copyright law reform affect that?

[BLUG] major exploit in 2.4 and 2.6 linux kernel

There was a flaw discovered in the kernel that's been there since 2001
that can be used for privilege escalation. If you have support for one
of several less-common network protocols, a malicious user with local
access can become root very easily.

It has to do with how the kernel allocates network sockets and sets up
protocol listeners on those sockets. There are some functions that are
implemented for some protocols but not others, and when the function is
not implemented, it's supposed to raise a "Not Implemented" exception.
Instead, it references a null pointer. Vulnerable kernels have support
for Appletalk, IPX, bluetooth, pppoe, irda, isdn, and a few others.

>From Linus's commit:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=e694958388c50148389b0e9b9e9e8945cf0f1b98

kernel_sendpage() does the proper default case handling for when the
socket doesn't have a native sendpage implementation.

Now, arguably this might be something that we could instead solve by
just specifying that all protocols should do it themselves at the
protocol level, but we really only care about the common protocols.
Does anybody really care about sendpage on something like Appletalk?
Not likely.

Even better is RedHat's mitigation advice:
https://bugzilla.redhat.com/show_bug.cgi?id=516949#c10

Best of all is this post I saw on PlanetDebian:
http://blog.bofh.it/debian/id_294 which reads:

cd /lib/modules/$(uname -r)/kernel/ && \
rm net/ipx/ipx.ko net/irda/irda.ko net/x25/x25.ko \
net/ax25/ax25.ko net/bluetooth/bluetooth.ko \
net/sctp/sctp.ko drivers/net/pppoe.ko drivers/net/pppox.ko

Basically, if you use bluetooth or some obscure networking protocol in
your kernel and someone else has local access, you might be vulnerable.
If you remove the modules for those vulnerable protocols, you're fine.

Head North. Find one of the areas that supply popple for
the Duluth particle board plants. They have a humongous machine
like a mower, and cut the trees in swaths -- with enough swaths
to let each get back up to the size they want before mowing again
(several years). New popples grow up from the stumps of the old
ones. (In Virginia, the oaks do that, too -- quercus
sempervivens, in effect -- though it takes a lot longer.)

Why should the grand total be the criterion? Mowing
popples for particle board (or paper) has to be a net
subtraction, whatever the grand total is doing.

Straw man. Question is how the poets & playwrights would
eat, while still working full time on their writings.

Agreed. Someone had to do the GNU work before the idea of free

look what's happened out of that.

You know, that's a point I hadn't considered yet. Cutting down trees
as a good thing...

If you planted a large enough forest (or a fast-enough growing woody
plant) specifically with the intent to set yourself up to continuously
cut down significantly sized trees for the purposes of carbon
sequestration, that'd be one thing; I could be okay with that,
someday.

Right now, as I understand the number of trees on the planet is still
dropping regularly, I find it really hard to think of that as a really
great idea to be pursuing just yet.

That's a good point.

I attended an in-service training day led by a teacher, advocating
something called "Layered Curriculum", who does not have a single
biology textbook for her high school classes; she has dozens of them
at all reading levels from 6th grade to postgrad, as well as
collections of audio-visual material.

When she's covering a topic, if a student wants to read up on it they
are then better able to select a text appropriate for them as an
individual, whether they're a hypo- or hyper-fluent reader, an
auditory or visual person, etc.

It's taken her her entire career to build up that collection, and I'd
bet it's mostly if not completely copyrighted.

I'd like to see such a collection available to every teacher in every
school on the planet, whether they take Kathie's pluralistic approach
or simply choose the *one* book they best like.

No argument here. I doubt you'll find any argument from anyone else on
the front lines, either.

Precisely.

Copyright and patent law, while perhaps originally encouraging output
of sciences and useful arts, are now being used as weapons counter to
those goal.

The most effective way of fighting against the Copyright and patent
regimes, I've come to suspect, is just to show them up by doing their
job better for free.

Then the argument that "without copyright, and people being granted
practically unlimited and indefinite monopolies on certain work,
nobody would produce those works" would be demonstrably false.

I'm happy to see people working on that.

I know what you mean. I'd guess you were a surprisingly early reader
and you were encouraged to gorge yourself on any subject that caught
your fancy.

I had that sort of experience in school, myself.

Most kids need a good teacher, though, to model the educational
process. And I bet even you had a better experience in classrooms
where the teacher, though largely irrelevant to your own needs, took
care of your classmates needs well.

My main point is that resources spent on teacher salaries and
professional development would likely bring greater returns to our
kids' educational experience than the newest edition of the Pearson
math textbooks.

Yeah, if a kid is able to prepare themselves enough on their own to
pass the evaluations, why not? They'd merely be one more kid to worry
the teacher if they're made to sit through the class anyhow...

I feel a little pessimistic that this would be a popular usage of the
materials, and fear the idea of parents forcing their kids to do such
things, but I agree it would be awesome for those that took advantage
of it by their own choice.

Off topic, perhaps: when reading this paragraph, I was reminded of the
feeling I always get when on the Wikipedia: "If only I'd had *this* as
a kid...".

I mean, I was the kind of child who entertained themselves reading
encyclopædia articles (think World Book level, not Britannica; at
least not 'til much later...), but I exhausted our encyclopædia and
ended up frustrated for lack of further reading on most subjects.
That, and we were missing 2 or 3 of the volumes (loaners never
returned) so some articles referred to by the others I simply did not
have access to.

If I'd had the Wikipedia, who knows what crazy topics I'd have gotten
into as a child...

Yeah, I don't quite get the Kindle edition stuff. It is only marginally
less expensive than the paper version, and you can't share them with a
friend when you're done. Passing books on to friends is one thing, but
there are open book swaps in places, and you certainly can't swap Kindle
books with strangers.

That's nice.

Oh, you are certainly correct. Printing things out in convienant packets
is an easy use of the technology that is not allowed with current paper
book licenses. It isn't really interesting in any sense, though it could
well be highly useful in the short-term.

> It's the fact that the teacher can remix and match and personalize the

I think the attitude of freedom that comes with using free materials
will really start some things changing. That, in itself, may well be
really interesting.

I don't have enough faith in our current system to expect that we'll go
primarily paperless within my lifetime.

We could have had videophones in the 1950's. We could have traveled to
Mars and back in the 1970's. (Shoot, I don't think a person has stepped
foot on the moon during my lifetime.) Back in the 1980's they said the
computer would allow us to have paperless offices, but instead it was so
easy to create new, better, longer forms that the amount of paperwork
a person does has only skyrocketed.

Not to mention it is possible that paper is beneficial to the
environment by way of carbon sequesteration. (Reduce CO2 by having more
carbon stored in books.) If we get science to back that as a viable
solution to global warming, we could well see a future government
initiative to create -- and store -- more paper-based products. If this
were to happen we could well see a great influx in the amount of paper
materials. This may sound like a crazy idea, but I fully expect much
more crazy ideas to be leapt at as we start to see more disasters caused
by global climate change.

Actually, what I like about it is while it would make it easy for a
school to use a book that literally doesn't mention evolution at all,
it would be equally possible for students to download and read other
science books. If a student (or family) is unhappy with the lack of
evolution, it becomes trivial to work around it.

Compare to the situation now, where if a district doesn't like evolution
they can either purchase books without it, or glue pages together and
the student or family has no way to work around it. (Particularly if
such books are also missing from their local library.)

Heh. You speak like someone who does this with Youtube. I find Youtube
to be such a huge waste of time I never go there directly -- I wait for
someone else to provide a link to something. I let my friends waste
their time on Youtube, and only look at the gems.

I have absolutely no problems with books being aligned to standards. It
makes sense to have a standard grade in which to teach things, as it
makes transitions between school districts much, much easier.

I just wish kids had more time to actually learn the material, instead
of needing to focus on learning the test.

I think just providing light to the fact that these materials exist and
are mature enough to be used wide-spread will do wonders.

With California as a state doing this, I fully expect smaller, poorer
areas to start using some of the same books and handing the material
out as packets. Then you could well start seeing it happen in middle
class suburbs where they decide they can keep their athletics programs
by cutting textbook costs. Once it reaches that stage there will be no
stopping it. Wealthy areas will not want to hear that poorer kids have
good, modern books while carrying light-weight backpacks to school.
It'll could literally be a race between districts that are adopting it
to be hip-and-modern and districts adopting it to trim the fat and save
money.

I fully expect it to spread life wildfire. It is just, I also expect
a great portion of those students to primarily consume the materials
via print.

In a way what we're seeing is sort of the return to the values of the
gentleman scientist of years gone past. They shared knowledge, as the
sharing helps everyone. They wrote books, certainly, but they were
rarely primarily dependant upon the book sales to make ends meet.

When people can contribute timely material to their peers without
concerning themselves with how to squeeze the most money out of the
material, then everyone benefits.

One of my problems with education was that I regularly undervalued the
part played by teachers. Part of that was that my preferred learning
style is listening to lectures and reading. As a child I absolutely
hated all hands-on activities. It was a massive waste of time.

Couple that with the fact that people consider "good" teachers to
frequently be the ones doing a lot of hands-on activities, and, well...
My idea of a good teacher was one that didn't actively get in the way
of my educating myself. -- I had a couple really bad teachers, but with
the exception of an art teacher that really stood out... teachers, in
general, never really seemed key in my education.

Things get interesting, though, when a kid who loves a particular
subject can study up on the material during the summer. To my mind, it
opens up the possibility of children skipping or testing out of some
classes due to being self-taught... using the same materials used in the
class-room. This would have been a delightful idea to me as I both loved
to learn new things and hated to do what I considered busy-work.
