Interviews: Ask Technologist Kevin Kelly About Everything 135

Posted by timothy from the if-forrest-gump-were-smart-and-ambitious dept.
Kevin Kelly has for decades been involved in some of the most interesting projects I know about, and in his roles as founding editor (and now editor at large) of Wired Magazine and editor of The Whole Earth Catalog has helped spread the word about many others. Kelly is probably as close to a Rennaisance man as it's possible to be in the 21st century, having more-than-passing interest and knowledge in a range of topics from genetic sequencing and other ways that we can use measurement in pursuit of improved health to how technology is used and reused in real life. Among other projects, he's also the founder of CoolTools, which I consider to be (unsurprisingly) the closest current equivalent to the old Whole Earth Catalogs. (Disclaimer: I've had a few reviews published there, too.) (He's also one of the founders of The WELL, now part of Salon.) Kelly is also Secretary of the Board of Directors of the Long Now Foundation, the group which for years has been designing a clock to ring on 10,000 years in the future. Below, ask questions of Kelly, bearing in mind please the Slashdot interview guidelines: ask as many questions as you want, but please keep them to one per comment. He'll get back soon with his answers.

We cut our server room from 20 or more machines down to just 8, each running 4-6 virtual machines. We backup VMs between hosts in case of hardware failure. In 4 years it has run amazingly well.

      They're using 256 dual core Atoms, for 512 cores at 1.6Ghz. Those 2.3Ghz Opterons will do roughly twice the work per core as the Atoms, with eight cores per chip, four chips per box, a 1U box will replace roughly 32 Atoms, requiring 8U to achieve the raw power of the 10U SeaMicro box. Those 32 processors run 80W ACP each, so including memory, disk, and chipset, you're looking at 3-4kW under load, versus 2-2.5kW for the SeaMicro.

      So how much will this thing cost you? The CPUs are $500 apiece. $300 for a 1U case. $800 for a board. $60 for a 4GB stick of registered ECC DDR3, times eight per processor. $275 for four 120GB SSDs. You end up around $6K per box. Now the SeaMicro uses Infiniband for its internal networking, for communication intensive tasks. Lets do the same. $900 each for dual port 40Gbps cards, and another $6K on a 36-port QLogic switch.

      That adds up to just over $61K, versus $150K for the SeaMicro box of roughly equivalent performance. For nearly three times the cost, you get maybe a third lower power consumption. At worst you have double the power consumption, an extra 2kW, and say one more for the AC. That's 30 YEARS before you make up the difference in initial cost. Therein lies the problem with SeaMicro claims. They compare power consumption against hardware two and three generations old, the servers that are going to be replaced. If you actually compare them against new hardware, they're pretty mediocre.

      • atom only has a very short time when it will be relevant (some argue its no longer relevant and some even say it never was due to the chipset being the power hog, not the cpu).

      Neither are coherent topics.

      Am I the only one that sees the blurb at the top is about asking some guy at Wired questions, yet all the comments are about low powered chips used in servers?

      • It appears the comment stream got merged with the article that discussed Mozilla's use of SeaMicro servers [slashdot.org]. Oddly enough, the Mozilla article now has no comments...

          This ^ . I was replying to the low-powered servers article, not anything about some technologist named Kevin. I was referring to the fact that the article synopsis misspelled the word "at", instead saying "st", hence the intentional typo in my post.

  • this sucks, i was planning on heating my home from the heat given off by servers.

  • It looks like you've been involved in many projects. I've got about 10 different side projects (outside of work) going on at any given time in several different realms. How often do you decide it's time to end a project so that you can focus on a better project? Have any projects that you devoted a lot of time to result in nothing or have all come to fruition in one way or another? What is your criteria for this?

    What insights can you provide to the /. crowd about building the clock?
    Project management anecdotes about the clock project?

  • Will there be an actually clock completed (other than prototypes) before the 10,000 years are up?

  • and how do i become one?

  • Where did everything come from ?
    I feel everything is too far away, is this a common perception ?
    There seems to be a lot of useless stuff around, are you happy with the composition of everything ?
    If we could change the form of everything, what should we change it too ?

    Does this make me a troll ?

  • One purpose of the Long Now Clock is to encourage long-term thinking. Aside from the Clock, though, what do you think people can do in their everyday lives to adopt or promote long-term thinking?

  • I still cite Out of Control as the most readable introduction to the oft confused subject of complexity, and am right now wading through What Technology Wants but finding it far more forced (sleep inducing). While I clearly don't disagree with the idea of seeing technology as a partner with humanity [meme.com.au], your newer book reads like you have invested too long in a world constructed from your imaginings and cut back your level of interest in looking at what is actually going on, an interest which seemed to pervade

    • I can understand your frustration with What Technology Wants. Having come to similar conclusions as Mr. Kelly on my own, I find the way that he relates the idea rather slow and repetitive. However, the idea that he is asking you to take in and think about is so difficult to explain without sounding like it's taking place in a dorm room that I appreciate what he's trying to do. I find even the name Technium kind of silly, but he could have puzzled over what word to use for years. Better to go with a silly na

  • Kelly is probably as close to a Rennaisance man as it's possible to be in the 21st century, having more-than-passing interest and knowledge in a range of topics from genetic sequencing...

    Since when was genetic sequencing a hot topic in the Renaissance? I'd be more impressed if he was fluent in stained glass artistry, music composition, and Latin and Greek.

  • OK, I'll take TFA seriously and ask a serious question. I have a good idea of the answer, or parts of it anyway, but I'm interested in other viewpoints.

    Q: Why don't we have fusion power yet? What are the specific technical, political, economic and social obstacles to replacing dirty fossil fuel and potentially catastrophic nuclear fission power plants with nuclear fusion plants? I know this is kind of a "where's my flying car" question, but I feel that if our society really wanted affordable, practical

  • I know that you did a lot of travel when you were younger (e.g. backpacking in Asia for years). How important was that for your status as a "Renaissance man"? Would you still recommended extensive travel to young people, or has globalization changed the opportunities?
  • What is your philosophy on software tools? Do you prefer to use a lot of small pieces, loosely assembled, using scripts to join things together and get things done, or do you like to find a software suite (such as Office) and work within that?
