[BLUG] Blender Users Group

I forget whether I had mentioned this in my previous e-mail and am too
lazy to check. But we're having the first Blender Users Group meeting
tonight at 7pm in Fountain Square Mall room 008. Check the website for
details:

I'm not surprised. Have you been following the law suit?

Microsoft was fined by the EU for not allowing reasonable access to
documentation for interoperability. Then once MS created a program for
interoperability, they were fined for making it too expensive.

Of course, in this country MS can spin it however they like...

(Thanks for the congrats!)

Cheers,
Steven

Let me support the idea of some one speaking in encryption.

Most people are at-will employees. This means that there employers can
fire them at any time for any reason (or no reason at all) except for a
small list of things protected by Federal Law. Thus, an employer can
fire a black employee because he does not like him, but not because he
is black. This makes for interesting jury trials. Most employers have
the good sense not to use their full powers under the law, because doing
so would upset the remaining employees. Companies where most employees
are upset tend to do poorly in the long run.

If you were paying attention when Starr was using the full power of his
office to try and cause Clinton trouble, you saw some cases somewhat
like this, except that it did not involve encryption. In the US you can
be forced to testify about most matters unless it runs afoul of the 5th
amendment. The courts have ruled that if you are offered immunity then
the 5th amendment does not apply. (I think this even applies with offers
of very limited immunity, but check with your attorney if it is
important to you.) The charge that will keep you in jail is contempt of
court. The good news is that they can keep you there only while the case
you want to testify in is active.

A woman who was suppose to know about Clinton's finances spent several
years in jail while Starr was investigating Clinton. According to her
side of the story, Starr wanted her to testify in a particular way. She
said that if she told the truth, Starr would prosecute her for perjury.
I don't know what was the truth in that particular case, put I do know
that I would be worried if Starr wanted to make my life difficult.

Postcards? Letters? Mail? Does anybody do that any more? You mean I
have to pay per envelope and it can take days to get to the
destination? Why would anybody want that?

Just kidding, of course. In many cases an employer has a right to
monitor employee emails, at least according to articles I've read. I
wonder what happens if the employer wants to read an email that an
employee has sent using GPG (using the employers email server). If the
employee refuses to provide the passphrase (or just decrypt the
content) for the employer upon request, what happens? Could they
terminate the employee? I have not idea how this might work.

I've read some articles about law enforcement forcing people to
disclose passphases for encrypted content or face jail time. I find
that scary, not becasue I'm hiding something, just because it seems
like a privacy violation.

Very interesting topic indeed!

Very true. I suppose it depends on the type of "sensitive" material
being sent. On my personal account I don't think I've ever sent an
encrypted message that would cause any really serious problems if
someone knew it was sensitive and even manged to decrypt the content.
I might get very upset that someone had accessed my "private" mail,
but that's about all that would happen.

At work we have a different method of secure file transfer when
encrypted email is not an option. In general I don't send anything via
my work email that I wouldn't want read by my supervisor or even the
general public. Working for a .edu I know there may be public record
laws that may affect my messages, but I'm unclear exactly how those
laws are applied, so I tend to err on the side of caution.

There are a couple of issues I have with encryption for *every* message:

* I only correspond with regularly with about 5 people who actually
have or use GPG keys. Getting everyone I communicate with via email to
use encryption for every message is not likely to happen in my
lifetime.

* reading messages on mobile devices really isn't an option if they're
GPG encrypted, at least not that I'm aware of. The sensitive messages
shouldn't be read on a mobile device anyway, but I like to be able to
read non-sensitive stuff on the go. Again, in my case disclosure of my
routine email messages wouldn't be the end of the world. For others
this could very well be different depending on the type of "sensitive"
messages.

I am definitely not saying that encrypting every message is
impossible, just that for me I personally don't have anything I send
over email I view as critical enough to justify the extra effort
involved in this.

Of course I still want to learn more about GPG and encryption in general.

Barry mentioned Pidgin in one of his messages. I use Psi on Windows as
my Jabber client, and it integrates with GPG for IM encryption. Just
an FYI in case anyone is interested. I'm not sure if there are other
Windows IM clients that do this or not.

One more GPG related item and then I'll get back to work: I have an
Aladdin eToken, which is a small USB smart card that functions as a
card reader too. Private keys are generated on the device and can't be
exported or otherwise leave the device. I bought it mostly to play
with and learn about smart cards and two-factor authentication. It'll
authenticate with Active Directory if the AD environment is set up
just right with a certificate authority. What I really want to do now
though is generate a private key on it and use it with GPG on Windows.
I gave up after trying, though I don't recall the technical reason
that I couldn't get it to work. PGP's paid version does this, I think
with the same model eToken. I did manage to get an SSH private key
generated on the token and use it with Putty on Windows and also with
the openssh client on linux. Not that I need the added security for
anything, it's just fun to try it.

Sorry for the long-winded message. I'm not trying to start an
encryption argument (especially as the "new guy"), just presenting my
views based on my very limited knowledge of the topic. I'm fine with
continuing the encryption discussion on the mailing list if people
want to or just waiting until the meeting if that's preferred.

I hope to attend a few BLUG meetings in the near future!

Kevin

Re: [BLUG] More tasty Wine goodness

Thanks for the tip - I'm looking forward to trying it out.  As I am a musician, I may have to check out Fruity Loops too. . . .

FireGPG allows you to type of text, then encrypt it right in the
webform. It is a nice idea, but...

By the very nature of the product, it can't set the headers right to
indicate that it is actually encrypted. This causes mailers with good
GPG/PGP support (like Mutt) to fail to recognize that it is GPG encoded
without special hacks which sniff the body of the mail message.

It is a solution if you're trapped in webforms and don't have access
to decent mail applications with good GPG support. It isn't a good
solution, though. It actually can make things much more of a pain in the
ass for people who do use mail apps with good GPG support.

(Yes, I use mutt. I can respond to Outlook events, but managing them is
up to me.)

Cheers,
Steven Black
