    Once it becomes cheap enough to visit Mars with regularity, be it for simple science or tourism, it would actually make sense to establish a permanent base, rather than bringing everything along each time.
    You're extrapolating an aweful lot from an analogy that only has superficial significance.
    It's not extrapolation. (Nor was it my analogy in the first place) I believe that once the cost of the trip is reasonable, people will choose to stay on the other side. What you are saying is that the cost will never be reasonable. This is like--to continue the analogy--stating that in 1493, that no average joe will *ever* sail west across the Atlantic, and that every voyage would need to be funded by royalty. So it took perhaps 130 years before that was not true... so? I agree that the cost will be prohibitive for a long, long time. But that doesn't mean that it will always be.

    In short, no, AFAIK. No LEMs, no Surveyors, no Lunokhods... But you could ask more here.

    I believe it is because modern lunar orbiters have focused more on mapping minerals and such rather than on high-resolution imagers like the absolutely huge HiRISE.

    How long would the US settlers have lasted if they'd had no natural resources apart from lots of very very salty / acidic dusts and regolith, a dim sun, low gravity, and had faced instant death in the event of a loss of air pressure / failure of any of several thousand literally "mission-critical" systems? Oh wait, for some of those failure modes, death would be slow, lingering, and unpleasant.
    Even in the relatively temperate climate of North America, there are plenty of ways to die.

    Regardless, I've actually thought along the same lines about colonization, and it has a lot to do with the economic rationale for going in the first place. Once there is one good reason to establish a population, everyone else follows to support that population. Columbus thought that we'd settle to get gold and silver, at Jamestown it was tobacco (eventually), in New England and Atlantic Canada it had a lot to do with just leaving Olde England and perhaps a very little to do with cod fisheries and fur trading. But once those settlements started, other economic activites were established to support the local population.

    Much, much, much better than that travesty known as Clearcase (+ Clearquest) which perversely probably killed CMVC when IBM bought Rational out.
    I am a very casual user of CMVC through scripts written by folks who know what they're doing, and it is as you describe in regards to levels attached to bugs... but from my little experience with it, the database of versioned files seems to be a bit removed from the filesystem metaphor that everyone is used to. It's a little harder to flip a switch and go browsing version 2.3.2.13 using cd and ls-- but as with any versioning system, it's only as powerful as the group using it and how they decide to use it.

    But yup, we're moving to ClearCase, which seems to have some very powerful capabilities. Problem is that it seems I'm somewhat forced to understand them, and the CC lexicon, rather than just shoving my updates in a level. I'm still a dumb, non-power user, but I have many more possibilities to screw things up, it seems.

    True. Today they asked how to use CMVC. 3 months later, they will say that IBM did not tell them how to open the file, or did not provide a text editor to read the files.
    In disclosure, like 87 years ago, IBM provided them with a physical server with CMVC installed so that they could browse the code in all its versioned glory to their hearts content without even having to install CMVC. And that's good, because installing CMVC is probably as easy as playing wiffleball in a hurricane. But the point is that SCO has had access to this information for years-- they just didn't care to go looking for it.

  13. Re:What? What? on Could HP Beat Moore's Law? · · Score: 1
    As far as I can tell this has nothing to do with standard processors and everything to do with FPGAs.

    It seems what they propose is: Instead of the FPGA configuration bits being done with gates on the silicon wafer, why not perform configuration by configuring the metal-to-metal interconnects? After all, if the metal layers are thick compared to the interconnects between them, you can blow connections you don't need like blowing a fuse. By removing the FPGA configuration bits from the silicon wafer, they can save a lot of space, leading to higher speeds and lower costs.
    Aha, thanks for digging through the awful press for the real story. If the interconnect is non-volatile and reprogrammable, then there are likely memory implications as well.

  16. Re:Racism more troubling that "fairness" on The Return of the Fairness Doctrine? · · Score: 1
    the problem seems more related to a tendency to present extremely complex issues in a simplistic binary manner
    I think a bigger problem is the credulity of the media. They rely on "idependent" reports and studies to create soundbites like "GAO reports that Medicare Prescriptions actually costs 79 trillion dollars a year" or "AAUW reports that even though far more women are going to colleges than men, schools still short-change girls." And that is it... straight from the press release to the telepromter, often without even at glance at methodology or even a mention of the political agenda of the organization funding the study.

    So, what's fair? Reporting every biased claim issued by either side without comment? Or is actually stepping back and mentioning that the study was funded by a political organization and the methodology sucks? Kucinich doesn't want both sides fairly presented-- he wants the media to report that the "facts" used in opposition to his agenda were created by big corporations. This fairness doctrine will just end up with the media not questioning those facts because it's fair to treat both sides like they're not making stuff up.

    while current performance microprocessors won't be made this way (too much power to dissipate), there are plenty of other microelectronics which uses power in the hundreds of milliwatts range. These, you could stack 10 high.
    Given that current Intel dice appear to be about 50% cache, it would be nice to be able to slice the cache off and put it under the processor. Might be able to make the access path from the different memory banks more symmetric. Or, since DRAM and flash processes are tailored differently than logic processes, you could replace the SRAM cache with DRAM or flash from wafers processed entirely differently than the processor wafers.
