Weird Asteroid Itokawa Has a Dual Personality

astroengine writes "We care about how asteroids are made, in large part because if one were aiming to smash into us, we'd like to know what we can do about it. The structure of asteroids is also a matter of scientific curiosity, as it tells us a bit about the formation and evolution in our solar system. ... 25143 Itokawa is a relatively small near-Earth asteroid that was visited by the Japanese Habayusa spacecraft in 2005. It has also been monitored by Stephen Lowry of the University of Kent and his colleagues over a twelve year span with the 3.58 meter New Technology Telescope in La Silla, Chile. In that time span, Itokawa has made five near approaches to Earth. And what did they find? The asteroid is composed of two lobes of different densities, suggesting that Itokawa is in fact a merged binary." ESO is hosting a preprint of the paper.

      Its the type of wood (or of several types of carbon, glass fiber, titanium, etc...) layers used in its assembly that dictate the offensiveness of the blade (in a defensive-offensive scale). The gluing, the thickness and the relative placement of the layers also are important in defining the type of the blade, and in conjunction with the type of the rubbers they set the type of the complete TT racket. There are several thousands of commercial blades and rubbers, so the choice is enormous ;-)

      Usually its the top layers in both sides that count more to the offensive-defensive grade. Blades are usually symmetrical (both sides are equal) but there are some models prepared for defense in one side and for attack in the other. The offensive blades have usually harder outer layers that cause a faster rebound of the ball when compared with defensive types.

      No one is willing to do that any more because it is quite clear that they do not read the emails. By all appearances, by sending an email you are sending your comments to /dev/null. As a side affect, no one else (read: the general Slashdot user base) will know that you also do not approve of the beta abomination. Emails to a dead mailbox, uncounted or analyzed for content, can easily be dismissed as a vocal minority.

      In contrast, posting comments in the stories is a very public statement that everyone sees, everyone knows about, and can not be denied later when it is a complete failure. And the "editors" (I use that term very lightly) most definately do read the story comments... they themselves frequently comment on stories.

      Over and over again for the last several months you will see long comment strings speaking very explicitly to the problems with the beta redesign, including:
        - Massive waste of screen space. Do Slashdot readers really need to see "Latest Tech Jobs" and "Top SourceForge Downloads" taking up 1/3+ of every screen? What about the massive whitespacce this leaves down in the comment sections.... you know, the portion people actually look at? What is next in the beta, to fill these areas with massive flashing/dancing graphics 'ala a Japanese bulletin board site?
        - Useless graphics that contribute nothing to content or understanding articles. Huge pictures, often taking more screen space than the story summary itself.
        - Complete disruption of comment readability and flow. With the existing format one can easily scan 15-30 comments in a single pageframe and scroll for more. The new format lets you see 3-5 at most in the page frame and you continually have to click "Load More" to see additional comments... a format that completely breaks page refresh and following a link off-page and then back.

      And the many, many other insightful analysis of the existing beta problems brought up by other regular readers for months. To date, as far as I can tell, Slashdot has failed to address any of these issue, give any response to complaints, or given any accounting of acceptance rates, email/click-thru/or otherwise. Slashdot has repeatedly posted blurbs about how great the new website is, and how everyone likes it. The comments in existing stories show quite the opposite. We have all seen website crash and die, and regular readers all see Slashdot pulling a Digg death-dive with this new beta.
