ER1 Personal Robot Reviewed
Makarand writes "The Mercury News is carrying a review of
the ER1 Personal Robot
from Evolution Robotics Inc (of Pasadena, CA). The ER1 resembles neither a dog
nor any robot in sci-fi movies.
It is a 3-wheeled platform (resembling an industrial table) holding a laptop (running Windows)
for its brains and a Web camera for its eye.
The ER1 sells at $600 (laptop not included). For an extra $100 you get a completely assembled ER1.
Evolution plans to sell expansions like grippers and infrared sensors in the future. If your laptop
is Wi-Fi capable you can drive the robot around inside your home or control it using the Internet from anywhere."
According to a new Aberdeen Group report, open-source solution Linux has surpassed Windows as the most vulnerable OS, contrary to the high-profile press Microsoft's security woes receive. Furthermore, the Aberdeen Group reports that more than 50 percent of all security advisories that CERT issued in the first 10 months of 2002 were for Linux and other open-source software solutions. The report muddles the argument that proprietary software such as Windows is inherently less secure than open solutions. And here's another blow to the status quo: Proprietary UNIX solutions were responsible for just as many security advisories as Linux in the same time period. Could Windows be the most secure mainstream OS available today?
"Open-source software, commonly used in many versions of Linux, UNIX, and network routing equipment, is now the major source of elevated security vulnerabilities for IT buyers," the report reads. "Security advisories for open-source and Linux software accounted for 16 out of the 29 security advisories--about one of every two advisories--published for the first 10 months of 2002. During this same time, vulnerabilities affecting Microsoft products numbered seven, or about one in four of all advisories."
The stunning report makes several claims that seem to fly in the face of widely accepted beliefs. First, the Aberdeen Group says that Windows-based Trojan horse attacks peaked in 2001, when CERT released six such advisories, then bottomed out this year, when CERT didn't issue any alerts. However, Trojan horse-based attacks on Linux, UNIX, and open-source projects jumped from one in 2001 to two in 2002. The Aberdeen Group says this information proves that Linux and UNIX are just as prone to Trojan horse attacks as any other OS, despite press reports to the contrary, and that Mac OS X, which is based on UNIX, is also vulnerable to such attacks. Even more troubling, perhaps, is the use of open-source software in routers, Web servers, firewalls, and other Internet-connected solutions. The Aberdeen Group says that this situation sets up these devices and software products to be "infectious carriers" that intruders can easily usurp.
According to the Aberdeen Group, the open-source community's claim that it can fix security vulnerabilities more quickly than proprietary developers can means little. The group says that the open-source software and hardware solutions need more rigorous security testing before they're released to customers. This statement is particularly problematic because many Linux distributions lack the sophisticated automatic-update technologies modern Windows versions contain.
We can rail against Microsoft and its security policies, but far more people and systems use Microsoft's software than the competition's software. I believe that we'll never know how secure Linux is, compared with Windows, until a comparable number of people and systems use Linux. But despite the fact that Linux isn't as prevalent as Windows, we're still seeing a dramatic increase in Linux security advisories today. I think the conclusion is obvious.
Slightly OT I know, but is there any good information online about creating your own robots? There is a ton of CHEAP old PC equipment on eBay you could use as the brain for a robot, but I would have no clue about interfacing PC hardware with motors and such. That would be an awesome project to work on, but where to start?
Any links would be appreciated... and I personally think that passing this information on to a fellow geek, and giving them some parts (motherboard/other PC hardware, motors, etc) to mess with would be such an awesome Christmas present.
And yes I know of Lego Mindstorms, but it seems like you could be even more creative if you had more control over every aspect of the robot you are building.

This is completely off-topis, but karma is for fools.
I enjoyed Dude, Where's My Car.
Not every movie has to have some epic tale, oscar winning acting and million dollar effects.. Sometimes all they need is a smoking dog. Heh heh, smoking dog.
