  1. Re:True Story: on Does the Octopus Hold the Key To Robot Design? · · Score: 5, Informative

    If you don't mind me asking, what happened to 'Cephus'? you speak of her in the past tense.

    She died of old age. When I got her, I had found her on my SCUBA tank after we had returned home. She was soooo tiny (about the size of my thumbnail), and we were miles away from the ocean by that time. I did not want her to die, so we mixed up some artificial sea water and I carried her home to place her in a 100gal aquarium I had. Fed her with feeder goldfish, but clams and crabs purchased from the local pet store was what she really enjoyed. She lived about two years (which is very good for an octopus), grew to about 13 inches and finally died from old age.

  2. True Story: on Does the Octopus Hold the Key To Robot Design? · · Score: 5, Interesting

    Octopuses have intrigued scientists for years, because they have both long- and short-term memory, they remember solutions to problems, and they can go on to solve the same or similar problems. They have been known to climb aboard fishing boats and open holds in search of crabs. They can figure out mazes, open jars, and break out of their aquariums in search of food.

    This part of the linked article rang very true for me.

    True story:

    Octopus are underrated. Seriously. I used to have an (Octopus bimaculoides) as a pet (her name was Cephus, short for Cephalopod) and I was always amazed at the intelligence and problem solving abilities she exhibited. One day I was returning from working all night at the sleep lab followed by a day of class. I had a new bag of goldfish to feed her and placed them in the "goldfish tank" across the table from her 100gal aquarium. She always got excited at that and would hang on the side of her tank and look at the goldfish. At any rate, I got a couple hours of sleep and then ran back to work for another all night shift. Upon stumbling back home the next day, I was stunned to find no goldfish in the goldfish tank! I did not know if I was just seriously sleep deprived or what, but closer inspection revealed goldfish scales floating around in Cephus's tank........and a trail of dried salt water on the table top from her tank to the goldfish tank. She had opened the top of her tank, navigated across the table to the goldfish tank, helped herself to every last goldfish in the goldfish tank and then crawled back home, closing the top of her tank! All I could do was stare in dumbfounded amazement.

    She also exhibited curiosity with new objects placed into her tank, exploring them extensively, and I must admit, it is most interesting in that unlike other aquatic non mammalians.....when you looked into an octopus eye, they look back at you. There is something absolutely intelligent behind those eyes.

  3. Re:Investors on HP CEO Carly Fiorina to Step Down · · Score: 4, Interesting

    HP calculators were well thought out, and engineered tools that simply did the job well and I have purchased a series of calculators, culminating with my 48sx (replaced with a gx when the sx died). From the early ability of HP calculators to be programmed with everything from sophisticated algorithms to the first "computer" game I ever played (Moon lander anyone?), HP has been the company to purchase calculators from. RPN notation and the concept of the Stack in a calculator truly made them a workhorse allowing one to be productive.

    When HP decided to let their calculator business wither, everybody was stunned. We wanted to see the calculators continue to expand with new methodologies for connectivity (USB, 802.11, Bluetooth etc....), storage (CF), etc....etc....etc.... and could have easily become a growth market playing off the early success of the PDA market. Who knows? Perhaps an HP calculator/PDA would have helped prop up the PDA market to make them more useful? Embracing more open standards for communication and storage could have helped. Also, the understanding that "virtualizing" the calculator functions into an embedded OS that would allow other expansion options and ease of programmability with modern graphics (OpenGL) would have been great roads to take.

  4. Investors on HP CEO Carly Fiorina to Step Down · · Score: 5, Interesting

    Well, let's see..... I at one time did have shares of HP, but sold them after a series of decisions HP made under Fiorina including:

    1) Less focus on the printing division so they could make "me too" Wintel boxes and purchasing Compaq for an unbelievable amount of cash.
    2) Canceling then reinstating the HP calculator line.
    3) Getting out of and then back into the storage business.
    4) Failing to capitalize on technologies invented at HP.
    5) Being way too late to capitalize on the imaging expansion. Although the current imaging campaign (The Kinks Picturebook) is a well run ad campaign focusing on the consumer, they are still missing the Pro level stuff.

    If a company is going through significant expansion, one could excuse a series of screw-ups, but HP has not significantly expanded. Rather they have given marketshare to companies like Dell, Epson, Apple and others to the tune of about $10 Billion.

    My investment money went from HP to Apple. Fiorina was brought on to HP to bring the company into the Internet era, but seemed to miss that original goal entirely. Companies like Apple got it.

    Granted, running a company the size of HP is not easy, but Fiorina's hubris and arrogance have proven dangerous. Unfortunately, this pathological perspective is a model that American corporate (and political) figures seem to be embracing to their shareholders (and citizens) detriment.

    OK....... I cannot see what the near term scientific benefit is of sending folks to Mars. Hubble? Hell yeah. The moon? Absolutely, .......but Mars? Look, Hubble has generated more scientific data per dollar than just about any other NASA program as well as helped out more than one project in the defense department and fed data to scientists and scientific organizations world wide. A return to the moon, could certainly function as a refueling point for unmanned missions to other planetary and stellar objects, as well as functioning as a potential resource for mining (with a space elevator which would facilitate this), and a remote optical and radio telescope on the moon could be an extraordinary scientific resource, but I am not sure the payoff of killing Hubble in favor of manned missions to Mars are currently worth it. I would much rather see more investment in sophisticated ground and space based "scopes".

    Given current technology, I see a manned mission to mars as a financial boondogle.

    I am sure someone else will mention it, but I use iTunes exclusively for music throughout our home. A central server with our entire 10k song plus collection ripped onto it resides in the study with an old Powerbook connected up to the main stereo system in the house that spins out the tunes for most to hear (A Mac Mini would be perfect for this task). Others who want to listen to something else in differing parts of the house (or outside) can also tie into iTunes and listen simultaneously to completely independent streams, all wirelessly. In fact, before they moved, my next door neighbors used to stream from our server as well.

    I don't know if PIII laptops can run iTunes or not, but my six year old Powerbook spins tunes with no problem whatsoever. For those truly particular about their music ( or those with high end home stereo systems possessing digital audio connectors ), Powermac G5's and the new 17in Powerbook also have digital audio out. Combine that with Apple's lossless audio format and you have some kick ass tunage available without ever again having to search through your CD collection for that particular song. A cheaper option is to purchase Airport Express units for differing parts of your house that each have an audio out and can plug into any available power socket.

    Personally I think the main reason is the malpractice insurance that docs have to pay.

    This is certainly part of the problem. Let me give you an example: My mother (a physician), used to love delivering her patients babies. It was one of the high points of her practice. Then one day, we were going over her budget for the practice and we discovered to our horror that every baby she delivered was costing her $200 because of insurance and other costs. Note: she has never been sued either. So, we made the business decision to stop delivering babies. But here is the real galling thing: She has to maintain an insurance trailer that goes down a little every year, until the last baby she delivered turns 21!. Is it any wonder they tried to discourage me from going into medicine? Is it any wonder that physicians are abandoning medical practices left and right in this country? There are also other regulatory issues physicians have to deal with that would boggle the mind. No other business in the US has to deal with these issues to the degree that physicians do.

    The most critical item any computer security professional will tell you to take care of: Physical access. If you have a concern, this is your first line of defense and in fact, most top secret installations have considerable resources dedicated to physical access. Next down the line in terms of security risk will be issues related to physical access that again most top secret installations have resolved by disallowing any removable media in or around secured systems. After that comes any issues of network security because your greatest security risk is internal access.

    You should not be carrying any sensitive work related items or data home, but if you have personal stuff (or a home business with IT critical information) you wish to secure, short of establishing a computer "vault" with limited access in your home (actually had one once for a project I was working on), you need to start with a secure OS. This does not mean Windows, unless you can afford a "hardened" version and are skilled at management. In fact, I would say from your question that all of the things you are already doing are the absolute minimum if you are using Windows. If you are truly this paranoid and keep sensitive info on your personal computer, and you obviously have a connection to the Internet, it should also mean, physically removing the Internet connection from your computer at times when you do not need it. Multi-casting OS capable machines like certain flavors *NIX are helpful here, so you dont have to deal with Windows network wizard every time you connect back up (if you use certain settings for your network). Wireless should be a no-no as well. IF you are really (read pathologically or are doing something quite illegal) paranoid, you could also build a Faraday cage around your room and charge it to reduce risk of TEMPEST related probes, but again if this is a concern, someone simply breaking in (again access) is often easier and cheaper.

    When you are actually connected to the Internet, a hardware firewall is an absolute necessity. Network address translation will help limit some attacks. And aside from all the other things you are doing (strong passwords, encryption etc....), I would strongly urge you to constantly pay attention to your logs. Your most important data will be gleaned from the logs in terms of who is attacking, their strategies for attacking, when and where.
