  1. Sorry. PCI Rears its ugly head again. on McAfee Retracts Lowball Bug Damage Estimate · · Score: 4, Informative

    Even though it is Windows, there is absolutely no technical need for AV when the application is so limited.

    Fixed that. I am afraid that the Payment Card Industry (PCI) differs from your opinion.* In their infinite wisdom**, PCI has decreed that ALL computers need to be running AV. After, all, if it is good for the desktop, it must be good for the servers, right? And since a virus can be spread from anywhere to anywhere, all computers need to have their own protection.

    I know it seems silly, but many of the PCI Audit Drones actually believe this. I spent hours trying to convince an auditor that we did not need AV on a Linux server that cannot accept email and has no internet connection. If the PCI Audit Drone finds a computer without AV, you fail the PCI Audit. If you fail the Audit, you get marked as failing on a public web site. If you fail enough times, you lose your ability to accept credit cards. So the need to have AV on a POS is there, it is just not a technical need.

    The one I am most surprised at is Phoenix ONE. Although we are having a very cold year this year (it hasn't even hit 90 yet [32 for those outside the US], and we are already into April), normally cooling costs would be huge. I know they have done some work with chillers to replace air conditioners, but cooling that size space in 115 degree heat (46 Celsius) can't be cheap.

    Released in 1985, there were many features that were considered "revolutionary" by games that were released as much as 7 to 20 years later. Things like hidden stats that changed based on your actions, and changed the way an NPC would interact with you. (Some guilds wouldn't let you join if you killed peasants, while others wouldn't let you join unless you killed peasants. [plus the guild didn't always tell you what actions allowed or prevented you from joining.]) It also multiple stats such as hunger, fatigue, sickness, cold or hot, thirst, or how much you were carrying that actually changed how fast you could move. Movement seemed so much smoother than other 3D game of the time, and distant object came into focus gradually as you got closer.

  5. Re:It's obvious on Users Rejecting Security Advice Considered Rational · · Score: 1

    Exactly my point! Yes, early 80's was a decade or two ago. But that was when the policy of Change-your-password-often was conceived. But it is still "Best Practice" so we have to put up with password changes every 30 days. Personally, I think a 6 month change policy or, at the very most, 90 days between password changes is sufficient.

  6. Re:It's obvious on Users Rejecting Security Advice Considered Rational · · Score: 3, Informative
    A tough question, especially since "best practice" dictates that the password be changed often. I did a little research into this and found that UNIX is actually the culprit for needing to change passwords often.

    It seems that several year ago, the /etc/passwd file was world readable (since it had to be read in order to log in), and that both the username and password was stored there. (Now the passwords are stored in /etc/shadow which is not world readable.) It was fairly simple for someone to download a passwd file and then run it through a dictionary cracker to find the passwords. In the early 80's it was found that a dedicated mainframe could crack any dictionary word in the passwd file in about eight weeks. If the hacker only had access for a couple hours a day, it could take up to four months. (If a complex password was used, it would take much longer or possibly never be cracked.) Therefore, if a person changed his password every 30 days, he could be sure that by the time the hacker cracked his password, it had been changed.

    However, as computers became more powerful, the time to crack passwords from a passwd file became less and less, a better solution needed to be found. One method was to separate the password from the username into a shadow file, and make sure that the shadow file was not world readable. A cracker would need to break into the computer with root privileges in order to read the password file so that they could break into the computer.

    Unfortunately, the above explanation is long, complicated, and goes against "best practices." I have tried pointing that out to several "Security experts" without any success. Pointing out that passwords will be written down if they have to be changed often will not help much either.

  11. Re:Sounds excellent. What will it cost? on Sponge-Like "Swelling Glass" Absorbs Toxins in Water · · Score: 4, Interesting

    Cost is an excellent question, since there is already a product that does something similar that has been around since at least 2007.
    PRP (Petroleum Remediation Product) is made from beeswax and soaks up oils as well. Since it is so light, it floats on water and only absorbs the oils. The bee's wax encourages naturally occurring micro-organisms to eat. The microbes feast on the bee's wax and don't stop eating until all the oil is gone, safely, naturally bio-degrading the petroleum and the PRP itself.
    I understand that they mix ground up corncobs into the PRP to make a version that works without water and can bio-degrade oil on land.

    I can see only three reasons for the glass version.
    1. If it is cheaper to make
    2. Since you clean it rather than let it decompose, it is reusable. But the costs of making and cleaning still have to be cheaper than the cost of PRP.
    3. If the glass version will absorb chemicals that cannot be degraded by the micro-organisms that feed on the beeswax.

  13. Re:Lack of perceivable progress. . . on Should Computer Games Adapt To the Way You Play? · · Score: 2, Interesting

    Wizardry 8 did this well. You could start with fresh characters or imported characters from Wizardry VII. I started with fresh characters and the monsters in the first area were pretty hard. I started a new game with imported characters thinking that I would have a big advantage. Nope. Although my characters were more experienced and able to fight better, the monsters were also stronger. After making my way past the first area, I moved to an even harder area. Realizing I had forgotten something, I went back to the first area. Sure enough, the monsters that showed up were even more powerful. Later in the game, after I had moved my characters up several levels, I had an occasion to go back to the first level. Although the monsters were even harder than before, they were no match for my characters and I breezed through with no problem.

    The game was divided into areas and each area had different types of monsters. Each monster type had different levels as well. The neat thing was that there was an upper and lower limit to each monster's levels. For example, the first area had different slime creatures from a wimpy green slime to a very tough emerald slime. Slimes were not seen in other areas and an emerald slime could never do the same kind of damage that a giant wolf that was found in another area could do. Each area was tough, and if you went into an area before you were ready, you could be killed quite easily. Even if you were ready, you could be killed if you weren't careful. Rare was the time you could enter an area and say, "Wow. That was easy."

    I really liked that game, and the way it pushed you in each area. Grinding was almost counter-productive, since the experience gained for each type of monster was dependant upon its difficulty. Grinding away in one area only made the next area that much more difficult. I could sit and grind in one area for hours, or I could move the the next area and play for 10 minutes and get the same experience. Unlike other games, it was a great balance between playability and difficulty. Other people I talked to had similar experiences even though we had different playing styles.

    A classic SF writer that is often forgotten is Fredric Brown. Although his SF stories are often short (usually less that 1000 words) they are totally amazing and stand the test of time very well. One of his more famous short stories, "Arena" was used as the basis of a Star Trek episode by the same name.

    I personally liked his several short stories that dealt with time travel and the many ways that people tried to deal with them. My favorite story, "The End", deals with what would really happen if someone could make time run backwards.

    The real brilliance of his writing is that he could make you think without delving into political commentary and do it in just a few words. His stories were descriptive enough that you could picture the worlds he described, but not so descriptive that they limited the story to a particular time or place. Stories written in 1954 could have easily been written in 1994. In other words, truly timeless science fiction, something that is very, very difficult to do.

    It could be really, really great if the screens could be both tied together (reading page1 and page 2 of the same book) or independent (reading page 1 of one book and page 43 of the same book or page 1 of a different book).

    Think of the possibilities. In a textbook example, a problem refers you to a definition, illustration, or answer found in the appendix, or in a different chapter. Instead of setting a bookmark, scrolling to the appropriate section and then jumping back, you have one screen set to the area you are reading and the other to the appendix or other page and you simply look from one page to the other.

    Another example might be when a class assigns multiple books. You could have two books up a the same time, referring to both without having to close one and load the other.

    Teachers are given conflicting instructions on teaching. (leave no child behind, but teach to the highest level. Don't teach just so they pass tests, but you need to cram 1.5 years of test stuff plus the stuff beyond the tests into 9 months.)
