Now there was an image of an antenna farm on the earth below, implying you need a large collector area for this to work. However, the energy could be tight-beamed via a maser to a small antenna, perhaps - a small, light antenna mounted on the climber.

    I heard they have adopted a new name for the Microsoft cloud computing service because "Azure" just wasn't catching on - it didn't describe the service. The new name has gone from one extreme to the other though - very descriptive, but kind'a dull: "Secure Universal Computer Kernel". Since it is totally an internet related service, as an added bonus they get the right put an "i" in front of it - Apple style - just to show how cool they are...

    Thanks for taking the time to explain that. Makes a lot of sense, this idea of "Network Virtualization". So what they are building is a tool that in itself is ethics-agnostic - a tool that in the right hands can be something that greatly enriches our lives and our precious democracy, but in the wrong hands can become an instrument of oppression. I guess that latter possibility is what everybody is worried about. I think the whole point of my blog is that Stanford should take some social responsibility for this powerful, potentially socially-transformative technology they are releasing into the world and think about how it can be abused. Perhaps there is nothing they could do, even if they could imagine scenarios like, for example, China employing technology developed in the Clean Slate Program to greatly enhance its totalitarian control over its population. I would suggest, however, that there would be considerable social value in anticipating such scenarios and considering how they may be mitigated. Beyond that, I would argue that establishing Stanford as a centre of research into the social implications and political ramifications of this powerful technology may make a lot of sense.

  4. How should the Internet look in 15 years? on Do We Need a New Internet? · · Score: 1

    This topic has been discussed on slashdot several times before. It seems to me there is a growing consensus that this is not a good thing. Stanford University's Clean-Slate Program was originally conceived as a long term inquiry into two research questions: "With what we know today, if we were to start again with a clean slate, how would we design a global communications infrastructure?" and "How should the Internet look in 15 years?". I was quite surprised that TFA implies that by the end of the summer it will be running on eight campus networks around the country. Stanford University's Clean-Slate agenda appears to be entirely driven by big business - their seven corporate sponsors. Though they emphasise an inter-disciplinary approach, it turns out that the disciplines involved in this program are all technical or business and management oriented. They have not included disciplines appropriate to investigate social and political issues. Stanford's Clean Slate Design for a New Internet has no soul or social conscience. A new internet architecture such as proposed will open vast new markets and endless business opportunities - in short - a potential gold mine for the seven industrial sponsors. The fear is that the Stanford research program will trade off attention to social and political issues for expediency in the impetus to get the new infrastructure up and running sooner. I was so moved as to do some personal research into Stanford University's Clean-Slate Program a couple of years ago. See my blog The Internet is Broken!. Here as well you will find links to Stanfords site and the original proposal.

  5. Moon seems to have rotated in the past 400 years? on The First Moon Map, and Not By Galileo · · Score: 4, Interesting

    If you compare the lower sketch with an image of today's full moon, it seems it has rotated clockwise about 30 degrees since the sketch was made by Thomas Harriot. Compare the sketch with this moon map (scroll down, mouse-over) and locate Mare Crisium on both - a crater on the extreme right at between 2 and 3 o'clock on the map, but between 3 and 4 o'clock on the sketch. A more dramatic difference can be seen if you imagine a humanoid figure created by Mare Serenitatis as the head, Mare Traquillitatis as the thorax, Mare Nectaris as the left leg, and Mare Fecunditatis as the right leg. In the sketch, the impression of an armless figure is stronger. Comparing this figurene in the sketch with same on today's moon shows the "rotation" far more dramatically. When I compared the sketch to some other images of the modern moon I got the impression of a rotation approaching 60 degrees. I don't think we can attribute this apparent descrepancy to the optics, which I can't imagine would be able to rotate an image like that. We could easily imagine an error in sketching which may be accounted by his notebook being somewhat askew at the time he made the sketch. The last possibility is that perhaps the moon has shifted a bit in the past 400 years?

  10. Re:Not per se on SCO Owes Novell $2.5 Million · · Score: 1

    More specifically, the judge found SCO guilty of Breach of Fiduciary Duty, Conversion, and Unjust Enrichment.

    Section 8.1 of the 2003 Sun Agreement lifts the confidentiality provisions with respect to 30 versions of SVRX technology granted to Sun under its 1994 Buy-out Agreement with Novell, specifically stating that it "amends and restates" Sun's 1994 SVRX buy-out agreement with Novell. SCO had no authority to enter such an agreement.

    Section B of Amendment No. 2 to the APA provides that before entering into any potential transaction with an SVRX licensee which "concerns" a buy-out of any such licensee's royalty obligations, SCO must obtain Novell's consent. This provision requires either party who even "become[s] aware of any such potential transaction" to immediately notify the other in writing. The provision further requires that any negotiations with the licensee be attended by both parties, and that both parties consent to any such transaction. There are no exceptions to this provision. SCO had an obligation to keep Novell apprised of the facts concerning SVRX Licenses and failed to do so. Novell repeatedly demanded audits and accounting of the 2003 Sun and Microsoft Agreements.

    The Court declared that SCO was without authority to enter into the 2003 Sun Agreement under Amendment 2, Section B, of the APA. The Court concluded that SCO breached its fiduciary duties to Novell by failing to notify Novell and account for and remit the revenue it received from Sun as a result of modifying the confidentiality provisions of Sun's SVRX buy-out agreement with Novell. The Court concluded that SCO was unjustly enriched by retaining the revenues Sun agreed to pay to relax and amend the confidentiality provisions of the 1994 Agreement and Novell is entitled to restitution. The Court concluded that SCO wrongfully exercised dominion Novell's personal property, and that SCO's failure to pass through to Novell the SVRX Royalties due under the Sun Agreement was a wrongful act inconsistent with Novell's rights. The Court concludes that Novell has established SCO's conversion of the revenues due under the 2003 Sun Agreement.

Because of the rare chance of a false positive, I have to read through this long nauseating list of subject lines of the email identified as spam each morning. What a way to start your day! It is just so disgusting to read through that, I feel I need to wash my hands after.

Why can't they pass a law making ISPs responsible for allowing spam onto the internet? It won't stop the spam that is coming from countries that permit it but it is a start at fighting back.

  13. Mine the oceans! on Supplies of Rare Earth Elements Exhausted By 2017 · · Score: 1

    Oceans cover 70 percent of Earth's surface. We have barely begun to tap the resources that lie on the bottom of the sea. The ocean beds are rich in countless minerals. About 20% is thought to be covered by manganese nodules, which can contain as much as 2.5% copper, 2% nickel, 0.2% cobalt and 35% manganese, as well as titanium, aluminium, potassium, molybdenum, lead, strontium and other substances. The greatest unexploited mineral resources on earth are on the deep-sea floor, including manganese nodules; cobalt-rich manganese crusts that contain nickel, copper, cobalt, and manganese; and hydrothermal deposits that contain copper, lead, zinc, gold and silver. Deep-sea mineral resources are found in specific areas. Manganese nodules are half-buried in comparatively flat deep-sea sediment at a depth of 4,000-6,000 meters. Cobalt-rich manganese crusts cover the slope or top of seamounts like asphalt at a depth of 800-2,400 meters.

    I believe that in the future we will routinely mine the ocean and it will become a huge industry. We will have great machines that will work around the clock mining the sea floor.

    I loved the video! What a coincidence - just spent the last couple of days with similar problems, trying to develop a curve for an audio compression algorithm. I began with logarithmic curves, but in the end, chose quadratic curves in place of the logarithmic curves because they provide a very smooth transition from linear slope to curved. Though the logarithmic curves did as well provide a nice smooth curve, they had an abrupt transition at the point where that curve joined the linear slope. In the end, after algebraically factoring my Quadratic Bezier, I ended up with an incredibly simple formula: y = (x - (x*x)/coefficient). The problem is that the term (x*x)/coefficient can never be allowed to grow larger than x, and in fact, is limited to coefficient = 0.5. On the other side, as you approach a large value for 'coefficient', you essentially end up with y = x.

    I don't think that photosynthesis is efficient enough to provide us with any significant amount of energy.

Even so, that still doesn't give them enough energy to even walk around the block, let alone commute to work. When is the last time you saw a plant walking by?

    I've got a question for a physics graduate or anybody who can answer it. After reading for the thousandth time about all the ionized gasses in space, I suddenly began to wonder how many electrons were created in the Big Bang? Like - are there enough electrons for every atomic nucleus to fill it's shells - if they weren't ionized? Now, that seems improbable, because an enormous amount of matter was created after the Big Bang - created in stars and super novae. Then this matter that was created - were electrons created at the same time in proportion? ...and in the balance of things - how many electrons are there in the Universe and how many protons are there? ...and how much do all these electrons weigh? ...and all these electrons that were striped from interstellar matter to leave behind ionized gasses - where did they go? Well I would guess they are zinging along some magnetic field lines someplace, quite happy to be alive, but is there some place where they collect in huge clouds? I don't suppose that is too likely, because electrons are antisocial among themselves and stay as far apart as possible, but on the other hand, protons are like that too among their own kind, yet somehow manage to form clouds. So then you think about these huge clouds of hydrogen and helium nuclei, all longing for the company of electrons, but there are none to be found in the region - such huge imbalances must exist. Makes you wonder when matter finally conglomerates into planets and such that somehow there is suddenly just the right number of electrons available so that every single atom can fill is orbital shells. How does this come about?
