    AP-WORLD NEWSBURST 10 Jan 2019:

    BUSINESS:

    A spokesman for the Empire of Japan announced the successful launch of the last power-sat in their highly successful Laser Power Satellite System. The system, which provides 98% of Japan's power, has been extended to allow them to provide power to any point on the globe. "We can focus 10 terawatts of laser energy to any point on the earth. The market for our space based power is unlimited and unstoppable." said Energy Minister Hirohito.

    POLITICS:

    U.S. Trade Secretary Jenna Bush announced that all trade sanctions against the newly reformed Empire of Japan would be removed. "The Japanese are old and trustworthy friends of the United States. The restoration of the Empire should not be seen as an aggressive anti-democratic move. Instead, it should be seen as an old and honorable society returning to its cultural roots. We applaud them."

    FASHION:

    The World Fashion Expo in New York provided a peak at this year's hot fashions. For the second year in a row, chrome and silver were the materials of choice. The new fashion accessory for this year is mirror-silvered umbrellas. Elite fashion designer Mano had this to say about the trend- "Shiny Shiny Shiny. Is beautiful and functional, No?"

  2. I have a problem... on Fast Track to a CS Degree? · · Score: 1

    As you have aptly demonstrated, you don't need a degree to do programing work. So why do you want the degree?

    You obviously don't want the degree for the knowledge. What you want are credentials. Unfortunately, a degree is considered a magic ticket in our society. You can only get so far without it. So I do understand your desire to get it over with as quickly as possible.

    You are making a mistake that so many other engineers, scientists, and techies make concerning college. Namely, there is more to college than your major. You seem to think that you currently DO know enough to progress in your career because of your work experience and your self-study of the field. There is a very good reason that all university degrees require a spectrum of coursework for a bachelor's degree. It provides balance.

    If all you know is CS, then that is all you will be. You are 5 years into a 40+ year career. The skills and knowledge you will need as you go are going to change dramatically as you go. If you stay with a company, then your need for subjects like english and business are going to increase and your need for your technical skills will decrease. Exposure to the arts and the sciences is increasingly valuable because it gives you debth and understanding of the world around you. It makes it easier to communicate and relate to those outside your niche. A knowledge of history is useful, if for no other reason, than to teach you that there are patterns and themes to life at both the personal and societal level.

    If all you want is a pass to the next level of the game, I am sure you will find some way to get that piece of paper in about a year.

    But if you want more; if you want breadth of knowledge and scope and debth, don't cheat yourself. Take and enjoy every course you need for your degree. You never know what piece is the key to what you really need.

    Good luck.

  3. Re:MIRACL on Battlefield Lasers · · Score: 1

    I have a good friend who worked on MIRACL at the WSMR HELSTF site for many years. He tells great stories about things that happened out there. A few examples:

    - They once declassified an obsolete drum drive by running over it 3 times with an APC (security said it had to be 3 times ...)

    - MIRACL is a deuturium-flouride chemical laser (basically a specially designed rocket engine). They stored the deuturium as heavy water in a holding pond. During bird migration season, an unusual number of ducks would swim in the pond. It turns out that the ducks liked the heavy water. They floated just a little bit higher due to the higher water density.

    - A moth was once caught in one of the side-lobes of the main beam during a routine shot. The resulting ball of plasma blew a basketball sized hole through a heavy electronics rack several feet away.

    But my favorite was:

    A couple of times a year VIP's would decend on the facility to review it (HELSTF was constantly under threat of being shut down). The Congress critters and Pentagon brass would always bring along an entourage of "experts" - laser physics phd's, consultants, etc. The project manager had to assign two engineers just to watch these "experts" as they walked through the facility. They had a bad habit of "adjusting" anything with a knob, wheel, button, or switch. In a couple of cases when they didn't catch the "adjustments", it actually caused tests to fail WHILE THE VIPS WERE THERE - a very bad thing when your funding is iffy. My buddy made a suggestion and they implemented it. After that no more problems with undocumented "adjustments". My friend built a couple of "twiddle boxes" - working dials, lights, readouts, the whole works. They very prominently placed these devices on racks in the control areas. When the tour groups would go through, the manager would point to the faux-boxes as the system controls and data recording interfaces. Presto, no more problems with "adjustments" to the real system.

The aphids apparently were captive, and as far as the reseachers could tell, lived their whole lives inside the colony.

  12. A bit of advice on The Atlas of Middle Earth · · Score: 2, Informative
    1st What order should you read the books?

    Most people recommend that you start with The Hobbit and then continue on with the Lord of the Rings trilogy (Fellowship of the Ring, Two Towers, Return of the King). They are separate stories, though they are closely coupled. If you don't normally like fantasy, then I suggest you defer reading The Hobbit until after reading the trilogy (if you finish it at all). Why? Two reasons: a) The Hobbit is mostly backstory to the larger and more epic story in the trilogy. While helpful, it is not really necessary for reading the Lord of the Rings. b) The Hobbit was originally written by Tolkein for his children. The storytelling style is very much in the mode of a children's fairy tale. It is a ripping good yarn and well worth the time for adults, but its distinctly juvenile style can seem a little "cute" at times. Please note that a little of this style rubs off on the first few chapters of Fellowship. The style seems to "mature" rapidly as the principles get farther from home, so it may be seen more as a literary device than anything.

    2nd Do read the books before Fellowship is released in the theaters.

    From all that I have read Peter Jackson and his team are doing superb job of adapting the story to the screen, but it is STILL an adaptation. There is a depth and breadth to Tolkien's prose that cannot be captured on film no matter how good the director or the production. This richness comes from Tolkien himself. He was one of the premier philologists (historian of languages) of his time. He had a decades long fascination with creating languages and mythologies/histories to describe them. From these deep roots grew Lord of the Rings. No author before or since has been able to match the scope and depth of this story. To do so would take the two things Tolkien had: genius and a long lifetime of hard study.

    3rd Remember, Lord of the Rings was not written yesterday.

    Why is this important? Sometimes readers dismiss perfectly good books because they consider the style or the story archaic. If you do really enjoy SF, like Babylon 5, then you should give Tolkien a chance. You will recognize some very familiar themes and stories and characters. No author writes in a vacuum. Epic fiction, whether it is Beowulf or LOTR or Babylon 5, has similar themes. Later authors will often borrow and reshape much older stories, if only subconciously. Tolkien drew on the mythologies of Beowulf and the Der Ring des Nibelungen, and created a world. Strazynski drew on Tolkien and Doc Smith and a dozen other sources to expressed his own ideas about the future. All I am trying to say is that you will see familiar faces, if in a different form, if you choose to make the journey. It is worth it.

    The one thing that intrigues me about the article is not that big companies like DuPont are exploring new "smart" textiles, it is that the popular media has absorbed the idea that molecular nanotechnology is coming and is going to be a Big Thing. The idea of smart clothing is no surprise to anyone who read Drexler's ENGINES OF CREATION back in the late 80's, or for that matter anyone who reads a fair amount of SF, or has the least bit of technical knowledge and imagination. I find it simply fascinating and funny that popular culture is "discovering" these ideas many decades after they were first proposed.

I know that online commerce is about as safe as in person transactions (safer in some cases). I just cannot shake the idea that they are going to keep my credit card on file.

I don't want credit. I want online money. Credit cards have burned me several times in my life: everything from my step-kids "borrowing" my card number (from an old bill) to buy something online, to merchant fraud, to credit card mis-charges. I have credit cards, but I don't LIKE credit cards.

Unfortunately, to work it must FEEL as easy and as safe as tipping a waiter or dropping coins in a street performer's hat. Credit card based systems will not do that.

Many good and useful things can be accomplished by leaving the security of Earth. I will not belabor them. There are many good books and articles on the subject. A few of the books are THE THIRD INDUSTRIAL REVOLUTION by G. Harry Stine, MINING THE SKY by John S. Lewis, HIGH FRONTIER by Gerard O'Neill. There are many others.

    The practical reasons for going to space are many: knowledge of the Earth and her surroundings, almost boundless untapped energy and material resources, a challenging frontier to inspire. Certainly no serious case can be made that pursuit of space exploration and development will harm mankind in any substantive way. The most casual examination of the facts makes it obvious that a sea of almost unlimited prosperity surrounds our little blue marble of a world. Space pointedly destroys the zero sum game for humanity.

But on the other hand I think we have to be a bit realistic sometimes (as a race that is). ... and I do happend to think that even the wildest and most amazing projects should be evaluated based on questions like: "what can we gain as a race in doing so", or "would we gain more using the money on earth instead".

    First a point of order. Humanity as a group has done nothing to date. Various individuals and groups are responsible for the achievements normally attributed to human kind. We do not operate as a race. That individuals are capable of taking responsiblility for the ultimate fate of humanity is the key to our future. "As a race" we have done nothing for our race. As individuals and in groups, we have lifted ourselves from the life of mere animals.

    What do we gain? What we gain is the future of not just humanity, but all life. What we gain is the chance to better our knowledge and quality of life in the short term (the next few hundred years). In the long term, the single greatest effect of humanity expanding into space will be the Greening of the solar system. Life will expand out from this fragile birth-world. With luck, the life will spread beyond our little solar system. To date, we know of no life outside of this planet. We humans are the best chance that earthly life has to spread beyond this world. If we fail, then all life will eventually perish. When the Sun eventually dies, earthly life will become utterly extinct. The Sun will die. Humanity need not die. Life need not die.

Since the whole organic food movement started as a response to the use of pesticides and (to a lesser extent) the use of man-made fertilizers, then there is no practical way for organic farmers to increase their crop yields.

    Given this, so called organic foods are doomed to either low volume "status" foods or they must consume greater and greater tracts of arable land. The third alternative is for organic farmers to adopt genetically enhanced foods. Specifically foods that have been/will be engineered for nitrogen fixation, drought resistance/low water needs, and increased yields. Without those enhancements organic farmers will be forced to farm lands until the land is dead. The whole reason modern farming exists is to avoid this problem.

    Any objections to the use of all genetically engineered foods, as opposed to objecting to specific foods for specific reasons, is the worst kind of elitist arrogance and fearmongering. The idea that genetically modified crops are going to "contaminate" and "cripple" organic farmers is just another way of propagating the "technology/science is bad...natural is good" meme.

    Yes there is a very real possibility that genetically engineered crops will spread their modifcations to wild plants via cross-pollination. This should be one of the main factors considered before a gene-modified plant is approved for release.

    OK, MacOS X on the whole looks pretty nice, but there`s one thing I simply don`t understand: why are they using BSD on mach? I mean, I do not understand the benefit mach gives them.

    Pardon me while I get pedantic for a minute. No offense is intended.

    One thing that people keep forgetting about Apple is that they are a hardware company. Heck, even Apple forgot that for a while and almost died as a result. Since Apple is in the business of designing, building, and selling non-commodity hardware (lets face it, intel/AMD boxen are commodity items), they are in the position of being in complete control of how the box works. Which means everything in the OS and apps should be tweaked down as hard as possible to get the best performance, right?

    Wrong. Apple is in this for the long haul. Several times in their history they have had to completely redesign both their hardware and their software, while also maintaining that illusive requirement of Backward Compatability for the masses of Mac faithful (heck I know people whose primary home machine is STILL a MacPlus, and they are fellow techies!). That means that Apple is basically in a state of constant porting of their OS to whatever new hardware they decide to manufacture. Remember, Apple is trying to create a stable and flexible software system that supports their bread & butter sales: hardware. (yes, I know it is a bit more muddy situation than that, but that is closer to the truth than any other assessment).

    A microkernal architecture does make porting a little easier by abstracting the OS interface to the hardware. Yes it slows things down a little, but not that much. You also get lots of nice advantages. Think of it as contingency planning:

    - Apple might have to move off of the AIM PPC design to something else (a very real possibility if Motorola can't bump past 500mhz G4s very soon)

    - They might choose to attempt a raid on part of an Wintel/Lintel/Sun/SGI market segment (I doubt it, but they might) and need to port over to some other architecture while still maintaining code compatibility with the MacOSX main branch

    - They developed OSX with the promise that it would run on G3 machines or better (boy was there alot of grumbling about THAT. Mac people keep and use their machines a LONG time). Some of those machines are now 1&1/2 generations out of date (2+ years). It just makes it simpler to abstract not only the microkernal, but everything in the new OS that they can (which is what they have done)

    - They need to plan for the unknown. They don't know what the future holds techwise. They want to make sure they can maximize their response as quickly as possible (say for example if USB2 supplants Firewire/IEEE-1394).

    There are lots of other good business reasons as well. One is that by abstracting to a microkernal, they don't have to exhaustively test every stinking OS upgrade on every type of OSX legacy machine. They can instead pound the heck out of their currently manufactured machines and then do restricted testing on legacy machines. Since the microkernal is identical on the machines and the microkernal gets exhaustively tested on all machines (a much smaller job), it eliminates a whole class of hardware unique bugs. That saves both time and money testing as well allows them to bring more features to market faster.

    Another reason is security. How many potential security holes can you plug by not letting ANY software, including the OS, touch the hardware? The answer, alot. Apple has a tradition of this sort of abstraction. How many older MacOS developers bypassed the ToolBox API to talk directly to the hardware, only to find that in the next machine their software broke? The answer: many. If Apple tells you "don't rely on attribute X being there in the future" then don't expect it to be there. Additionally, the various flavors of BSD are considered by many to be the most secure OS on the planet. Using a microkernal architecture to take away potential hardware backdoors should make it even more secure.

    Anyway, that is my assessment of why they chose the microkernal direction. I could easily be wrong. It could be something much simpler than that: we have this NeXT code, lets use it.
