  1. Re:Ringworld Builders on Ringworld's Children · · Score: 1

    That only works for the half of the ring closest to the core. The outer half is still exposed. And as the ring rotates....

  2. Re:Ringworld Builders on Ringworld's Children · · Score: 1

    You are correct on the cause of the fall. Another reason that the Pak aren't the builders. They would immediately have started fighting among themselves without outside assistance.

    That doesn't mean they see it as desirable. If they were going to do a construction project of literally stellar magnitude, they are intelligent enough and compulsive enough to design something that would not put their descendants at risk.

    But the radiation protection only applies to ~1/2 the circumference. The rest is exposed. And if the core explosion lasts more than a month or so (which it would), more of the ring is gradually exposed over time.


    Plus don't forget: The ring is portable, even without FTL. If the Pak built it as a radiation refuge, they would have started moving out of the galaxy as soon as it was done to stay ahead of the explosion's wavefront. Just like the Puppeteer Fleet of Worlds did.

  5. Ringworld Builders on Ringworld's Children · · Score: 2, Interesting
    I've always had a problem with the Pak as the builders of the Ringworld. They would have realized that it would just become a canvas for endless clan warfare on an enormous scale. It is also too fragile, and inherently indefensible.

    Of all the races that Niven introduced, I always thought that the Tnuctipun were the best candidates. If a bunch of them survived the Slaver War in stasis, they might be paranoid about travel and exploration. Look what they discovered last time! They also like to mess aroung with the genetics of things, which would explain all the variation among hominids. The Pak could have come later, and killed them or chased them off.

  6. Re:Final Countdown on Blade Runner Is The Best Sci-Fi Film · · Score: 1

    Every SF plot gets one unexplained science freebe. Besides, can you prove that time storms don't exist?

    What paradox? There is a causality loop, but no paradox.

  7. Final Countdown on Blade Runner Is The Best Sci-Fi Film · · Score: 1
    IMNSHO, the best SF film of all time is the 1980 Final Countdown. Clean, simple, basic SF premise. No hokey technologies or bad science. Just a group of men faced with a philosophical/moral quandry in a classic What If situation.

    Number two would be the 1951 version of The Thing. Bad acting from James Arness and bad monster makeup aside, Howard Hawk's direction of John Campbell's short story is great. Real human interplay. The ending broadcast is especially good.

  8. Re:But can they train them to listen? on Training Nurses With Virtual Veins · · Score: 1

    Getting stuck with a butterfly can often have a LOWER incidence of success than with a normal sized catheter. The tiny butterfly needles tend to bend! If they are having trouble with a larger needle, it's probably a skill issue.

    Butterfly catheters are also shorter, which gives them a higher probability of slipping back out of the vein.

  9. Re:Wonder when... on Training Nurses With Virtual Veins · · Score: 1

    Not because they practice on each other, but because in many venues they do 10x or 100x more sticks on real patients than doctors do. It varies by location. In some, nurses do no IVs or blood draws, and doctors or phlebotomists do them all. Anestheseologists tend do be better than other doctors. Again, a matter of experience and contant practice. For the same reason, Interns can be the worst, and may have only textbook training.

  10. Re:Thank you modern science on Training Nurses With Virtual Veins · · Score: 1

    As a retired paramedic, I'll second most of the comments above. But I've never even heard of a case of a modern needle breaking, even while being used bouncing over dirt roads and railroad tracks. I've seen people with skin so tough the needles bent, but no breaks.

    As for an earlier comment about sitting still while someone tries for half an hour: Anyone can have a bad day, but there is no reason for the patient to put up with too much of that. The general rule should be "three strikes" and you're out, next batter please!

  11. Re:Limited Usefulness on Training Nurses With Virtual Veins · · Score: 3, Informative

    I've never seen a student come out of IV training (myself included) with any kind of competence. Just a familiarity with landmarks and technique. Practicing on classmates is better practice, and also generates some empathy for future patients.

  12. Limited Usefulness on Training Nurses With Virtual Veins · · Score: 5, Informative

    As a retired paramedic who has stuck needles into literally thousands of veins, I can tell you that this kind of tool is of limited value. Even if they can exactly mimic the tactile sensations of a needle penetrating skin and then entering a vein, that's only part of the issue. A much bigger obstacle to be overcome is the social indoctrination that you don't go around stabbing people and making them bleed. Once most nursing/medical/paramedic students learn to just DO IT, their problems drop way off.

    The traditional training method of having students practice on each other has a lot to reccommend it as a means of overcoming such reluctance. Anyway, a practice model would only get used in class a few times per student, and then they will be out assaulting real patients anyway. Increased training costs for limited benefit.

  14. Experience vs. The Production Line on Experiences with Laser Eye Surgery? · · Score: 1
    I had the older, physical procedure, radial keratotomy, which used actual scalpels. I had to go back for a touch up, and I had halos at night for about a year. I also was real sensitive to sunlight for about a year, but this might have been from wearing photogray glasses for years, so I effectively always wore sunglasses outside before the surgery. But I would definitely do it all over again.

    The guy I went to had done over 10K procedures (maybe a lot more, I forget.) So he was the most experienced surgeon in town. And he was good, no question. But the downside was that the way he had gotten to that high a number was by turning all phases of the process into a production line. On the days he operated, he would do 20+ procedures in a morning. There were two beds in the operating room, and while one patient was processed, the other was swapped out.

    Nothing went seriously wrong for me, though I did twitch the first time from being under-sedated. But anytime things are moving that fast there is a risk of error. Consumate skill can let a team recover from lots of problems, but....

    So while you should always get an experienced surgeon, you have to consider all the angles.

    YMMV.

  15. Re:No big problems here on Is A Catch-All Address Worth The Spam? · · Score: 1
    Well I've experienced another variant on this form. I have a domain where I have also used addresses like company_name@mydomain.com when I didn't trust the recipient not to sell the address, or where I wanted to ID the source for other reasons.

    So I can't turn off the catchall on my domain. Even with an RBL filter at my registrar, I still get tons of crap. In the last month, spam has gone from ~300/day to 1,800/day. Most of it consists of 4 to 8 identical messages addressed to random names at my domain. It comes from all different source addresses, but presumably from many spammers as there are lots of different products being hawked.

    I wish I could find a filter that would handle dupes that I could run as a POP proxy. Otherwise I guess I will have to set up my own mailserver, instead of using my ISP's.

    Can you prove a negative? That's whay this guy is asking in a way. The real question is "What is the cost of NOT finding security holes?" Lots of evidence for that!

  18. Propaganda and Samizdat on Ken Brown Responds to His Critics · · Score: 1

    Brown must be a disciple of Joseph Goebbels' "Big Lie" principle. And calling his column Samizadt is an insult to those who used the underground press to topple the USSR. Quite a combination.

    I can see this as a PDA and laptop replacement for guys like me who use both. Looks like the PDA market is going to crater in the next year anyway. They have just about all the right features except for 802.11g. I particularly like the accelerometer to protect the hard drive.

  20. Fiber Isn't What It Used To Be on Wiring a Neighborhood? · · Score: 5, Insightful

    I've been involved in two projects over the last 10+ years where we stubbed in fiber for new construction projects. It was never used in either case.

    I'd suggest running two or three sets of Cat 6 cable to each building. That should be more than enough for the forseeable future, and only a small price premium over Cat 5. After all, most of the cost will be labor.

    But run the cable in a buried, oversized PVC raceway. Then, if you need to run fibre, or anything else in the future it will be easy to do.

  21. Disappointing Replies on Kinder, Gentler Security Scans? · · Score: 1

    What a disappointing bunch of replies! I thought /. readers would have a better understanding of how "real" computing gets done. There is no such thing as "after business hours." The business runs 24x7.

    This isn't about workstations. I should have been more clear. This about money generating production machines. Operations doesn't care about workstations. That's an IT/Helpdesk issue. This is about thousands of servers and network devices. As I said, this is a LARGE company.

    This isn't about what's in a job description, or about a security manager deciding to go ahead regardless. Trying to tell Ops "We are going to scan you, so get used to it" is so far from reality it belongs on a "Tripping The Rift" episode.

    Doing limited scans to start is also not an option. NOTHING can be done outside a scheduled window for now. NOTHING can be done that isn't compliant with all the other existing restrictions, for now. Until we get the rules changed! Admittedly, most of the problem is FUD and Operations trying to do a CYA. But the rules is the rules. To get the rules changed, requires facts, and an alternate set of proposals. I was looking for suggestions for those alternate rules.

    Their issue is anything that might affect service delivery and uptime. A lot of this is FUD. I was hoping that people would suggest rules they use to guarantee that if there is a production problem, that it can't be the result of the scans.
