The other day I spent some time with Phil Burns and the guys from Blastyx. We had fun creating a quick video about some of my wireless business (80211.net)
and installation. I am still doing a lot of wireless R&D on
the side … outside of my day job at Agilix Labs. Blastyx is doing
some very cool work, and they have some very interesting ideas on where
to take next generation marketing. You can go and check out the
video … it’s the “Wireless Mountain Man” video …

Progress with Asterisk
Funny how small the world is. I’ve been coming up to speed on the Open Source Asterisk
PBX solution. One of the first things that you have to purchase
are the cards for the PC that connect to phone lines. For my test
solution, I want to have two phone lines connected into the PBX to do
some basic call handling/call routing/voice mail/e-mail notification.
In reading up on this, the technical terms for what I want are FXO line cards. These are cards that act like a modem or phone and can “answer” calls. (NOTE: the other type of cards are FXS cards which allow you to connect a telephone to the PBX and the FXS card will “ring” the phone and provide dial-tone.) There are several solutions out there … from cheap to quite pricey! I found a Digium 4-line card that can have FXO or FXS modules attached to it. For what I am doing right now … it’s too much money.
There is also a lot of talk about the Intel chipset modems that can work. Many Asterisk web sites refer to these as the X100P or X100P-clone
cards. These are single-line cards that are actually “modems”
with voice capabilities. In looking into this, I saw mentions of
the $65 card … and that’s more what I was looking for. The best
part is that I found the link to DigitNetworks and they are selling the X100P cards
for $39.99. Even better … they are on sale this month for
$25.95! I just picked up two of these and ought to have them in
the next day or so.
So with these two PCI cards, I’ll be able to install them into my Linux
box, and then install and configure Asterisk to use them. This
ought to allow me to have the two lines answered – for two different
companies – and walk the caller through a series of prompts to transfer
them to the correct extension, or voice mail box. I’ll blog more
about it as I make progress.
So why is it funny how small the world is? It turns out that
DigitNetworks is just up the road from here in West Jordan, Utah!
Converting DVDs and Videos for the Video iPod
I have to admit that it has been harder than I thought to find a free
solution for converting DVDs and various other digital movies into the
right format for the iPod … on Windows. Yes, yes … I know …
if I was using a Mac then it would just be there. But I’m not …
yet. (NOTE: I’m seriously interested in buying a iBook,
PowerBook, MacBook at some point soon … and I will.) For now,
my primary laptop is running Windows, with Linux in Virtual PC.
My Tablet PC is also running Windows. So I want a Windows
solution. There are a number of commercial application that look
good … but I wanted to see what I could find for free.
I bought an iPod Video a while back, and have been doing most of my
experimenting and research on the audio side of things. I moved
from the music and smart playlists into podcasts. I’ve learned a
lot, and see some very interesting ways that this platform can be
leveraged into new businesses and business models. So what about
video?
I’ve had a long experience with video and video editing … starting
with 3/4″ tape decks in the late 70’s … and all the way up to my
current digital video editing set-up. I wanted to know how to
easily take a DVD, or existing digital video content, and get it
converted to MPEG4 format and moved into my iPod. Here’s what I
found that seems to work:
- For doing the conversion of content I’m pleased with Videora and their Videora iPod Converter. Based on the Open Source FFmpeg
project, this is a clean – and free! – application. It installed,
and was easy to figure out and use. Once you install it, you can
do “One Click” conversions, or create a queue of conversions and just
allow your machine to run all night. Videora has an insteresting
add-on that I might look at which is their automatic downloading tool –
Videora. So that is the solution for converting video to the proper format. - For grabbing video from a DVD, I found the Open Source DVDx
project at SourceForge. I’m going to test this tonight, however
the claim is that it will rip a DVD to various digital video formats
… which I can then feed into my Videora iPod Converter. It
appears to work easy enough, and there are other people using this tool
for this same purpose.
So I’m about to jump into really using my Video iPod and seeing what
might be interesting to take on the road. In my initial test, I’m
impressed by the size and video image … I’ll have to watch a few
videos to really see if I like it or not. In either case, I now
have two key tools to be able to get content into the right formats for
the iPod!

More and more autonomous
I know that this is older news, however I still love reading articles
about this race. This is truly amazing and is going to alter a
lot of things. The fact that a computerized car can drive itself
131.6 miles and avoid getting stuck. Oh yeah … and this is only
2005. So what are we going to be hearing about in 2010?
With the current rate of technological advances, five years is a huge amount of time for amazing developments to occur.

Next generation electronic companies
My father worked for Westinghouse Electric Corporation for over 30
years. While growing up I was introduced to the broad range of
products created and produced by Westinghouse … from appliances, to
power generation, to nuclear power plants, to military radar. To
me is was amazing the breadth of products and markets that Westinghouse
participated in … from consumer products to advanced military weapons.
This article reminded me of this same scenario with a slight
twist. The folks at iRobot are not only the producers of the
Roomba robotic vacuum cleaner, but also some very advanced military
robots. If you haven’t yet listened to the talk by Helen Greiner
– co-founder and chairman of iRobot – she gave a great presentation at Accelerating Change 2004. It’s very cool to see a company like this involved in such a wide range of applied technologies.

Remote control … using your brain!
There are many ways in which the interface between humans and computers
has evolved in recent years, however I think that the biggest jumps are
about to occur. This article is an example of just how far things
are progressing. We are now able to isolate specific thoughts
with electrodes placed strategically around the scalp.
My thoughts are not about how to detect thoughts of walking … but
instead how the detection of thoughts can be converted to new forms of
communications. What if I could think
about sending a message to you, and the computer would generate an
e-mail or an SMS message to you? I actually think that research
like this is taking us closer and closer to ‘artificial telepathy’ …
technology that will allow us to ‘think’ to each other.
Computer users move themselves with the mind.
Computer scientists have created a brain-computer interface that can

you have to do is think about walking.The technology detects brain waves by using electrodes placed at st… [KurzweilAI.net Accelerating Intelligence News]
Microsoft Research and Mesh Networking
I have been following the work that Microsoft is doing in their Windows Peer To Peer Networking.
This is actually some very impressive technology that allows for a
distributed set of users to create peer-to-peer groups for exchanging
data and information. I’m working on some applications (actually
plug-ins for GoBinder) that are going to exploit this
technology. Microsoft has put together a Peer To Peer SDK allowing you to perform name-to-IP name resolution (PNRP
– a serverless DNS technology), along with graphing and grouping APIs
for the transfer of data between the peers. It’s all very
impressive stuff … and is in all Windows XP SP2 machines … and will
be in all Vista machines. The bottom line … this is going to
drastically alter how ad-hoc groups of users on Windows machines will
be able to locate each other, communicate, and collaborate.
Today, I found yet another amazing technology out of Microsoft Research.
For years I have been tracking the “wireless mesh networking”
space. This is where each node in a wireless network is a
repeater/relay for any other node that is within range. With true
mesh technologies I can communicate with other users, even if they are
beyond the reach of my wireless signal, if there are one or more nodes
between us that are part of the “mesh” network. Mesh networks are
the next big thing … even the cellular carriers are talking about
adding emergency mesh capabilities into cell phones.
What I found today is that Microsoft Research
has code available today that will allow you to experiment with some
pretty advanced mesh networking using your Windows XP machine!
The Microsoft Research Networking Research Group has released their Mesh Networking software, and even an Mesh Networking Academic Resource Toolkit.
I’ve started to go through the documentation, and so far this is a very
impressive solution. They have embraced and extended some of the
standards that are currently being developed:
We implement ad-hoc routing and link quality measurement in a module that we
call the Mesh Connectivity Layer (MCL). Architecturally, MCL is a loadable
Microsoft Windows driver. It implements a virtual network adapter, so that to
the rest of the system the ad-hoc network appears as an additional (virtual)
network link. MCL routes using a modified version of DSR (an IETF protocol) that
we call Link Quality Source Routing (LQSR). We have modified DSR extensively to
improve its behavior, most significantly to support link quality metrics.The MCL driver implements an interposition layer between layer 2 (the link
layer) and layer 3 (the network layer). To higher layer software, MCL appears to
be just another Ethernet link, albeit a virtual link. To lower layer software,
MCL appears to be just another protocol running over the physical link.
I am really impressed to see this work this far along. I have
been waiting for years to see mesh networking hit the masses … and
this is now getting close. I’m now going to upgrade some of my
wearable computers to Windows XP just to experiment with this!

Phil Windley’s CTO Breakfast
This morning was the November/December CTO Breakfast that Phil Windley
put
together. The breakfast started with a question about hiring good
talent. One of the employees from Canyon Bridge
said they have been looking to hire some good engineers, and have been
finding that few can answer some very simple questions. The
example that they gave was about reversing the order of a linked list.
There was a lot of talk about how to alter the hiring process, and also what types of questions people ask: What do you do outside of work? What Open Source projects do you work on?
There was also a lot of talk about how to gather names. Examples
were leverage your existing employees to get the names of “known good”
co-workers. The problem with this approach is that you can
quickly run out of references.
The conversation went on for a long time before it finally went over to the CP80
issue. CP80 is the “Clean Port 80” initiative to create laws
which forbid certain types of content to be delivered over port 80 …
the standard port used by web browsers. It again becomes an
interesting way to attempt to legislate morality. In the end, it
will not be technically possible, but could give lawyers a way to go
after the producers of “unacceptable” content. Yeah …
“unacceptable” to who? ([tags: cp80 clean filter porn])
The conversation at one point moved to downloading content from the
Internet, and the subject of Digital Rights Management (DRM).
Several sites were mentioned where you could get free content – Pandora (which is a very cool streaming site – part of the Music Genome Project), and one of my favorites Epitonic. ([tags: free music learning])
There was a brief exploration of the whole area of Wikis and the
inability of the “average” user to use “yet another markup
language”. I have to admit that it truly aggrevates me that the
various Wiki platforms have subtle differences … and most do not
provide WYSIWYG editors. and we spent some time discussing the
fact that there is a not a really good – Open Source – AJAX/WYSIWYG
editor. I mentioned the fact that my parents can use Microsoft
Word, but that having to learn a whole symbology wasn’t going to
happen. It reminded me of a great Podcast by Robert Lefkowitz @ OSCON 2005 … I’ll have to blog about that one! ([tags: wiki wysiwyg editors language])
Phil Burnes through out comments about Flock … a very cool Mozilla-based project, I brought up a very cool article that a friend sent me from Make
Magazine … it was about Mologogo
… which is a very cool mash-up of Cellular phones with GPS and Google
Maps giving you a very cheap “real-time” geopositioning/geolocation
system. We wrapped up on one of my favorite subjects … wearable
computers. We didn’t spend a lot of time on it … I’ll have to
bring some of my toys to one of the next breakfasts! ([tags: flock make mologogo gps google googlemaps geolocation wearables])
On the way out, Phil brought up a good point. His gatherings
bring together an incredible group of people with diverse interests and
experience. It is the level of experience of some of the people
that really brings a great spin to the whole conversation. We
ended up going almost 2.5 hours … and it was a great conversation the
whole time … and we could have gone longer! I’ll look forward
to January!
