Bad Dream

02/01/05 | by JAdP | Categories: General Thoughts

It's been said that you're working too hard when your dreams are all about your work. Of course, 'tis also said that we solve problems in our dreams. Last night I dreamed that spammers were trying to infest our blogs with daemonic software. Now this is serious malware! This kept waking me up all night, rather early morning, as I hadn't gotten to be 'til after 1:00. I finally just got up to go back to work, and sure enough, an unwanted site had made it through our anti-spam defenses with a trackback.

Zapped now, of course.

No daemons either. :>

Coming Soon to a Cell Phone Near You

01/28/05 | by JAdP | Categories: Mobile and Wireless

... Just about everything it seems.

This past week has brought an amazing number of announcements on new services for your mobile phone or your wireless internet connection.

  • Television
  • Search
  • VoIP
  • MMORPG and other multi-player games
  • Business Apps
  • Education

I must admit that I don't really understand the fascination with squinting at tiny screens. 320x320 pixels - as on a decent PDA - is about as low as I can go.

However, whether you're accessing these, and other services, directly on your phone, smartPhone, PDA, Pad, Slate or TabletPC, your ability to do more on the move will increase dramatically this year.

Both Verizon and Cingular had announcements about TV on your cell phone. And Phillips is making the TV chips for your phone.

Yahoo...

local Y! Search

Y! Send to Phone

... Google and Ask Jeeves have all announced enhancements for mobile searching. Though I've been using Alta Vista on my Palm through AvantGo since the old Omnisky days - and still do.

Skype comes to your phone.

IDC says mobile gaming is the next big thing, as does Anita Wilhelm.

Of course, we've always been about bringing business applicaitons to you when and where you need it most, via whatever device you use; mostly extending data marts, business intelligence apps and collaboration tools into the mobile and wireless space. But recent announdements include:

And an interview in Innovate Online [free registration required] with Chris Dede, Wirth Professor of Learning Technologies at the Harvard Graduate School of Education has that

Dede argues that our definition of "learning technology tools" will continue to expand in response to new developments such as handheld gaming devices, massively multiplayer online games, wireless mobile technologies such as pocket PCs, and electronic "smart objects" embedded in everyday environments.

A great week for the TeleInterActive Lifestyle. :D

 

The Problem with 802.15 Wireless PAN

01/27/05 | by JAdP | Categories: Mobile and Wireless, ZigBee

IEEE 802.15 concentrates on wireless PAN for a variety of purposes:

  • Task Group 1a - WPAN 15.1 Revisions to Bluetooth (R) v1.2 published 2002 June 14
  • Task Group 2 - WPAN interoperability so that all those devices in the 2.4GHz don't interfere with each other, i.e. coexistence of 802.15 and 802.11 [WiFi] devices
  • Task Group 3a - WPAN Alternate High Rate MAC and PHY
  • Task Group 3b - WPAN 15.3 Maintenance
  • Task Group 4a - WPAN Alternate Low Rate MAC and PHY
  • Task Group 4b - WPAN 15.4 Revisions and Enhancements
  • Task Group 5 - WPAN Mesh Networking

UWB and WiMedia fall into 802.15.3 - There is no standard approved as yet. Proponents of UWB have been claiming for years that they will kill off Bluetooth - but there are neither products nor standards on which to base products. WiMedia wants to connect your [TiVo or Windows or... remember Sun Jini?] media center computer to your TV, stereo, etc. But 802.11 a or g or upcoming n do a great job of that.

ZigBee (TM) falls under 802.15.4 and finally had its standard approved on 2004 December 14. But if you check out ZigBee.org, there are still no products. ZigBee concentrates on low-power, low-duty-cylce needs replacing feedback loops for control circuits and sensors. According to their web site, their initial markets include home control, building automation and industrial automation.

Compare these lack of products with WiFi, other 802.11 derivatives and Bluetooth where products generally are announced in advance of the standards being ratified, with compliant products being announced near simultaneously with standards announcements. Bluetooth and WiFi have their markets identified and fill consumer needs or desires. ZigBee comes closest to doing this with its focus on sensors and controls requireing only a low duty-cycle, and I'll do a further study on ZigBee soon. But without clearly defined user needs, these standards are unlikely to make much of an impact in the marketplace.

 

Oracle Mobile Agents in New Form

01/23/05 | by JAdP | Categories: General Thoughts

Over the past two weeks, I've been seeing quite a few articles, like this one at Infoworld, that tout Oracle Lite 10g for grid computing. Most of these articles slant the announcement as though Oracle is just entering the mobile database market.

That's Just Not True.

Back in 1994 I worked for Oracle, and led internal roll-outs of some of their less marketable products, including Oracle Office, and its disconected client. And Oracle Mobile Agents. Mobile Agents provided an early true three-tier architecture to overcome the lousy (loosy?) wireless connections back then. Wireline modems were hitting 24KBPS back then, wireless was still around 2400 baud, with about a 90% drop rate. |-| But that started my love of the TeleInterActive Lifestyle and led to implementations on PalmOS devices and Novatel modems, and even our latest participation in a Wireless Logistics System for a regional trasportation company using WiFi and Symbol devices, with Netversant rolling out the network and Eleusinian Enterprises adapting their RFWarehouse product to ride on Oracle 10g, Oracle Enterprise Application Server, and Oracle Lite.

Oracle does need to adapt their pricing strategy though. This project really doesn't need Application Server; Oracle Lite and its Mobile Manager (child of Mobile Agents) would have worked just fine - but you can't get it without EAS. Upping the price of the software into an almost uncompetitive stratum.

If Oracle sold Oracle Lite and Mobile Manager by itself, it would be much more competitive with iAnywhere from Sybase and DB2 Everyplace from IBM.

 

Housing Bubble or Not

01/23/05 | by JAdP | Categories: Personal Life

Consultants must point out every conceivable risk, and we generally have the time and knowledge to do the risk assessment through tools ranging from simple 2x2 matrices to cause-consequence analyses to iterative Bayesean monte carlo simulations. Does such an onus fall on journalists?

Dan Gillmor writes about a piece in the Orange County Register that he picked up on his rerouted trip back to SF from Boston that seems to promote dangerous speculation in real estate. As Dan says, many experts fear that a housing bubble, similar to the tulip bubble and the dot-com bubble may be happening.

When I first moved to the Northern California Coast from "back East", I had a hard time overcoming "sticker shock" on housing prices. Back in 1984, a 3BR, 2BA house with an Ocean View were listing for over $180,000 and being bid upwards of $200,000. Much more than my houses in Delaware (45K$) or the one in Illinois (90K$) where worth.

The house I bought in 1999 has a tiny bit of an ocean view - actually, a pretty good white water view of Fitzgerald Marine Reserve from the edge of the driveway leaning out into the street. &#59;) I bought that house for just over 400K$ and it now appraises at 800K$. But I am only three blocks from the nearest DSLAM - killer bandwidth. :>> That must be the reason.

I'm still in shock. And I really wish I had bought in 1984 instead of saying "These housing prices can't go any higher". /sigh

But can they? I don't know. Bubbles are rarely identified until after they burst. And real estate here just goes up and up, with very few, and only minor, downturns.

Edit: One comment to Dan's post points to an economic analysis showing that the housing price increases are due to the wealth created by the stock market bubble. I don't believe this. The housing boom is a result of low inflation during the Clinton administration coupled with exceptionally low interest rates. Add in that interest on a mortgage can be one of the largest, if not only, tax deduction left to most people, and buying a house becomes cheaper and wiser than renting.

Edit: And to Dan's point, which I believe concerns responsibility in journalism... Does that responsibility extend to pointing out every uncertainty, every possible outcome, every risk? As consultants, we must do so. Must journalists?

I'm Joseph A. di Paolantonio and this blog has two main foci: my interest in food, and my interest in the future. This provides a look into my personal life, and is separate from my consulting work…though there will be overlap. I am an independent researcher, working as a strategic consultant and I'm an executive with over 20 years of commercial experience with a technical interest in the intersection of Internet of Things, with advanced data management and analysis methods. I view data science as a team activity, and I feel that the IoT must be viewed as a system. I am leveraging my past activities to understand the adoption and impact of the IoT; first, as a system engineer in aerospace, where I developed Bayesian risk assessment methods for systems within the Space Transportation System (including the Space Shuttle), Extreme Ultraviolet Explorer, Gravity Probe B, and many more, and second, as a enterprise data warehousing, business intelligence and analytics professional. Between my aerospace and IT careers, I indulged my hobby of cooking by starting a food company, Montara Magic, centered around my chocolate sauces. My education combined chemistry, mathematics and philosophy. I performed research into molten salt fuel cells in graduate school, and in photovoltaic materials for a short time in industry. The lure of bringing the human race into space was strong, and when I was offered the chance to combine my chemistry and mathematics skills to develop new risk assessment and system engineering methods for space launch and propulsion systems – I couldn't resist. I perform independent research and strategic consulting to bring value from the Internet of Things, Sensor Analytics Ecosystems and data science teams.I am a caregiver, a lover of science fiction and speculative fantasy, and my passion to learn has led me to a pilot's license, an assistant instructor in SCUBA, nordic and alpine skiing, sea kayaking, and reading everything I can, in as many topics as I can.
