	Mostly XMPP from where I sit, but that shouldn?t be a surprise. ChatSecure is available on iOS/Android, supports old-school OTR and OMEMO (which is what Signal uses). There?s more out there for Android, but I?m not au fait with it, and iOS?s options seem to be, at least for free, ChatSecure. On the Unix side of things, libpurple and the Pidgin clients all support OTR (including Adium), though I don?t think OMEMO. CoyIM has builds for Windows, OS X, and Linux. Everything I?ve mentioned is FOSS, which repos on GitHub if you don?t want to use the pre-packaged stuff as well.

	Old OTR works well, but can be kind of clumsy due to how the protocol sniffs itself. OMEMO is properly advertised, has a ton of support for different types of ciphers and can do key negotiation while one of the party?s offline. In basically every way a better protocol, but it?s more heavyweight, and doesn?t work with my client of choice (Adium), so I only really know about it from the XSF mailing list discussions.

	I think you?ll have a hard time finding anything that will do end-to-end encryption with group chats. It?s being worked on in the XSF right now, but nothing seems to support it well. Apple?s solution with Messages is to basically have your device send n copies of a message, each separately encrypted, without any real server support, like you?d find with something like IRC or XMPP MUC.

	PGP and OMEMO are supposed to work together, but as usual that comes with the normal PGP key management issues, and I?m unsure how much client support there is. Something like SSH isn?t going to work because of the way OMEMO distributes its public keys (from what I understand, it basically pre-generates a bunch of public keys which get stored on the server, each one is single use for a given messaging session, as the keys get used, new ones get put in).

> On the server end, I'm obviously looking for a clean/reliable solution...

	Good luck. Let me know if anything works out for you.

May 3, Wednesday
Building Open Source Random Number Generators, Rob Seward
18:45, LMHQ, 150 Broadway, 20th Floor, Manhattan

Many of our secure encryption systems depend on black-box closed-source
random number generators. After the Snowden documents revealed that the
NSA tried to undermine random number generation with the DUAL_EC_DRGB
algorithm, there is renewed interest in using open-source hardware as a
more secure way to generate random numbers. With this in mind I set out
to manufacture an open-sourced design on a small scale as a means to
disseminate knowledge about true hardware random number generation. In
this talk I'll discuss some of the thinking behind my project
http://www.openrandom.org.

Speaker Bio

Rob is an iOS engineer at Electric Objects. He has been fiddling with
random number circuits for about 10 years. He also makes art.

Just as an update, a couple of major bugs in MIPS support were squashed 
over the weekend in NetBSD, if you get the chance, try putting on a 
kernel from daily builds on your DOS partition and booting that. Curious 
if the slow I/O issue still persists.

They have decent specs (but only one gigabit NIC) and are pretty cheap.

Yes... you're right.  I saw it in the store quickly, and assumed it was
amd64 partially since it's from Asus.

Meanwhile, after I did the initial post, I was reading about uboot
configuration, and didn't update the thread.

I haven't seen it mentioned on FreeBSD-arm@ yet...

Don't get carried away with Asus or an android smart phone, if I was
permitted to say.
I see mine is a Octa Core, But according to me 4 cores out this are not used.

Just started learning it recently myself. The "Tour of Go" site is pretty
helpful if you already know how to program:

    https://tour.golang.org/list

The thing that struck me as I started to learn is how different Go is
from anything else I've ever encountered. It took me about a day to
learn Python (I had Perl and C under my belt at the time), but Go does
its own thing (some of it makes sense, other things I'm not so sure
about).

maybe this so-called-object-relational-mapping thing gorm
can give you a jump start?
