Fuel Cells, Remember them?

Tuesday, July 24th, 2007

A researcher at UC Davis has made breakthrough that could would lower the operating temperature in Fuel Cell systems, getting us closer to the “holy grail” of clean, cheap, renewable energy.

UC Davis News & Information :: Nanocrystals Key to Better Fuel Cells
A new way to make cubic zirconia with very small crystal sizes could be key to making hydrogen fuel cells more reliable and cost-effective.

The invention by a team led by Zuhair Munir, distinguished professor of chemical engineering and materials science at UC Davis, was recently included in Nanotech Briefs magazine’s Nano50 awards for 2007. The awards recognize technologies, products and people most likely to impact the state of the art in nanotechnology.

RFID Theft proof of concept demonstrated in Europe

Friday, December 22nd, 2006

A wise man once said :

One might note that easiest way to “prevent tampering, counterfeiting, or duplication of the document for fraudulent purposes” is to NOT PUT IT ON THE CARD.

This was in reference to the Federal Government’s decision to use RFID, as part of the Government Issue IDs that comply with the REAL ID act.

I hate to say I told you so but …

It will, we are promised, keep the unwanted and dangerous outside our borders, while streamlining entry for those welcome to come and visit.

But as the implementation of the scheme gets underway it is becoming clear that there could be serious problems with it.

Cellphones the new “Open Source” Frontier

Monday, December 4th, 2006

Something has always bothered me about cell phones. As they are become more and more complex, they have shifted from being mere communications devices to platforms for applications, but in my opinion we don’t have as much control over what applications are being run on our phones as we don on our PC. If I anted to could I wipe my cell phone, and boot it with an other operating system? In actuality I don’t know. (I don’t even own a cell phone. really) But I doubt it. Somebody correct me if I’m wrong. Here is a good reason why I think we need more control over our cellphones.

FBI using cell phone microphones to eavesdrop
In his memorandum opinion, Judge Kaplan described the roving bug as a “listening device” installed in the defendants’ cellular phones that functioned regardless of whether the phone was powered on. Many models of cellular phones, however, can have their microphones remotely activated via a download—even without the knowledge of the owners. That could be what happened with Ardito and Peluso’s cell phones. It is also possible that the FBI installed a bug directly on the phones. (emphasis mine)

This is not a post disparaging law enforcement. The article sited how this capability should be done. They go a court order to turn a cell phone in to a “roving bug”. But I can that if some intelligent yet unscrupulous hacker could sneak an app onto your cellphone to record your conversations, and send him the mp3. Remember phones are much more complicated now. Complexity is where hackers live. For all of our sakes and I think this has to be they net frontier in the open source movement. To have open source phones that we can use on any cell network. TO use open protocols so that they masses can examine, debug, and improve the protocols that the few engineers that dreamed this up will undoubtedly miss. I know you need to get buy fro the Cell carriers. They loose their “lock in” in such an environment. But if at least ONE forward think company emerges to embrace these methods, and provide free software to switch phones from other carriers to their own. And provide and open platform that developers can cheaply right apps for, and they can provide service and value on par with the major telecoms that might be disruptive enough to force other to do the same.

Google an Aid to Medical Professionals

Saturday, November 11th, 2006

Doctors using Google to diagnose illnesses | the Daily Mail
The internet search engine Google has added another impressive string to its bow - by helping doctors diagnose illnesses, according to a new study.

Researchers found that almost six-in-10 difficult cases can be solved by using the world wide web as a diagnostic aid.

It would be good to build dedicated health search index like for BSD,Linux, and the US Gov’t

Lockheed Martin wins contract to build Orion

Friday, September 1st, 2006

Lockheed Martin to build future moonship - Human Spaceflight - MSNBC.com
Lockheed Martin on Thursday won NASA’s multibillion-dollar nod to build the Orion crew exploration vehicle, a spaceship with a look and a mission that echoes the space agency’s giant leap to the moon in the 1960s.

The announcement kicks off an effort to produce spacecraft that would replace NASA’s fleet of space shuttles, due for retirement in 2010. NASA’s timetable calls for the cone-shaped Orion ships to bring cargo or up to six crew members to the international space station by 2014, and carry up to four astronauts to the moon and back by 2020.

For 13 months, two high-profile aerospace teams — one led by Lockheed Martin, the other led by Northrop Grumman and The Boeing Co. — have worked on paper proposals to fit NASA’s specifications. Now it’s up to Lockheed Martin to turn the concept into a reality.

I just hope the Work they do for NASA is better than what they deliver for the Cost Guard.

In my heart there will always be 9 planets

Thursday, August 24th, 2006

SPACE.com — Pluto Demoted: No Longer a Planet in Highly Controversial Definition
Capping years of intense debate, astronomers resolved today to demote Pluto in a wholesale redefinition of planethood that is being billed as a victory of scientific reasoning over historic and cultural influences. But already the decision is being hotly debated.

Officially, Pluto is no longer a planet.

Stolen VA laptop found

Thursday, June 29th, 2006

CNN is also reporting that the SSNs have not been accessed since the robbery. Not sure how this could be verified, but I do recall that file creation, modification, and access date & times of each file is maintained by the file system. It been a minute since I did any REAL work with a PC so I’m not sure. But I think that the more interesting stuff is at the end of the piece:

According to the documents provided to The Associated Press, the analyst, whose name was being withheld, had approval as early as September 5, 2002, to use special software at home that was designed to manipulate large amounts of data.

A separate agreement, dated February 5, 2002, from the office of the assistant Veterans Affairs secretary for policy and planning, allowed the worker to access Social Security numbers for millions of veterans.

A third document, also issued in 2002, gave the analyst permission to take a laptop computer and accessories for work outside of the VA building.

“These data are protected under the Privacy Act,” one document states. The analyst is the “lead programmer within the Policy Analysis Service and as such needs access to real Social Security numbers.”

The department said last month it was in the process of firing the analyst, who is now challenging the dismissal.

It is not the analysts fault for being robbed. It is the VA’s fault for having insufficient procedures for handling personal data, the analyst apparently followed established procedures for taking and handling the data. This is not just a problem with the VA but with corporate and government organizations all over.

I should get what I pay for

Wednesday, June 28th, 2006

The following is the best description of what Net Neutrality is about:

If I pay to connect to the Net with a certain quality of service, and you pay to connect with that or greater quality of service, then we can communicate at that level.(link)

Dap: Cobb

Others still don’t understand, when people who are “barely” aware of how technology works are allowed to make policy that effects it. This WSJ Opinion piece is an example of such cluelessness.

Meanwhile, Google, Microsoft, Yahoo and other Net neutrality proponents seem to want it both ways. They insist both that this is pro-consumer legislation and that the best thing is for consumers to pay for things that Google and other content providers would rather not. Net neutrality only became a cause of these companies and of the Moveon.org crowd when some phone companies suggested they might want to charge Google or other content providers for priority access to their networks.(OpinionJournal )

Understand what the enemies of Net Neutrality want to do. They want to be able to examine data packets as they come to and from their customers to determine what kind of applications/services they are using. (IE VOIP) This is called deep packet inspection. The ISPs then route those packets through faster, less congested routes if they are using “preferred” services provided by the them or business partners, (ie VoiceWing) or slower more congested routes for everybody else (IE Skype), or even block them altogether. This is called traffic shaping.

Lets be clear. nodes that are closer together can “talk” much faster than nodes that are farther apart. So if you are on VerizonDSL, I would expect that any service provided by them would have a technical advantage that services hosted outside of Verizon do not, but Verizon and other ISPs who appose Net Neutrality want to to be able to do is banish non sanctioned communication to the “surfaces roads” leaving the express lanes clear for only those who have paid a little extra.

You might hear tech people talk about how dumb the Internet is. This is true. ALL the intelligence of the Net is at the “Edges.” That means what make the Internet cool are the people, applications and services you can connected thought the Internet. The net’s jobs is simply move bits from point A to point B. And up until now the ‘net has used what is called “best effort” in determining how those bits get moved around. Now best effort will go out the window in favor what business agreement the ISPs have made with the content providers or application hosts. This is some old Microsoft bull. The ISPs want to leverage their position as the “platform” on which the Internet runs to skim of the profits of those that ACTAULLY INNOVATE. In much the same way that Microsoft leveraged its position as the dominate OS on which PC applications ran. Those that will not pay the ISP tax will suddenly have competition from some Comcast or AT&T sanctioned service to punish them or simple have there service diminished or out right blocked. And it will all be legal.
