  1. Re:Yet another reason for.. on Text-Mining Your E-mail · · Score: 2, Insightful

    That's not the point. The paper is talking about modeling spikes in topic/content of data streams over time. This is the second layer analysis of the meta-data that gets stored in the database.

  2. Re:why piggybacking wont work on GOVNET In the Works · · Score: 1
    Not only the issue of security clearance, but its already a pain trying to police the SIPPR net (secure military net) with people who are supposed to know how to play with classified systems. I can't imagine trying to do the same for members of congress, let alone each of the staffers underneath, government agencies etc. The secure military net exists for a different reason -- secure garrison and battlefield communication. It should also be said that the military already has TWO networks, SIPPR and NIPPR for secure and non-secure. They never touch each other. Those workstations on most peoples' desks usually aren't connected to the SIPPR net.

    After this weekend having Bush scold congress for leaking information to the press, I can just imagine the issues with putting them on the military network.

  3. More on the Lutris Situation on Lutris Closes Enhydra Source · · Score: 2, Informative
    I have worked with Lutris in the past with both Enhydra (version 2.3-3.0 and spec'd migration to the J2EE framework in enterprise) and there is more to all of this than just licenses from Sun and the J2EE framework. Don't get me wrong, what has been pointed out previously about the reference implementation and redeployment with different license terms would be an issue, but its more of a business trying to remain afloat.

    Lutris was a consulting services company to start with. Enhydra was developed by bringing together a lot of what they used to develop and deploy customer web applications in previous projects. Since they were a consulting services company first, an open source process served to both (marginally) push forward the development of the applications server with public support, but also create a low barrier to adoption for companies to get the services process in the door. I was a software director at one of those companies that adopted the process and then moved to bring in the consulting side to deploy a very large application on.

    Things were going great there when the economy was going great -- consulting services paid all the bills for the engineering crew to continue the primary development of the app server. The problem is when the economy turned south, the first thing to be cut were the consulting groups. Lutris had their contracts drying up and couldn't continue to pay the bills that way. Pretty soon they were left with a model that wouldn't work in an economy without a lot of free cash. There had to be another way to generate revenue or to go out of business. That model had to concentrate on traditional software development and open source companies haven't weathered that storm very well when there were commercial or other products that had more functionality or more entrenched customer bases. The quickest way to catch up was to push the enhydra enterprise process, use as much as possible to get it to a finished state (Sun ref implementation) and try to pull in product revenue with traditional sales. This couldn't be rectified with the open source licenses they were previously working on.

    It's economics. Sure Sun's license for using their implementation of things is going to effect that, but its an after the fact reason. The underlying problem is that a consulting services company with no contracts isn't going to stay in business... A software company at least has a fighting chance.

    I had friends that work(ed) there and this is not necessarily what they wanted out of things, but the survival instinct can be a powerful one. Has the discovery channel taught us nothing?

  4. Re:Oh, CRA me a river... on Genome Project Squabbling · · Score: 1
    A quote from their investor information: "To map all 80,000 human genes and find our SNPs, Celera is using Whole Genome Sequencing, a technique pioneered by several of Celera's scientists who were formerly at The Institute for Genomic Research. Using sound waves, a chromosome sample is dispersed into small DNA fragments that can be sequenced, then mapped back together based on their unique base-pair coding. In many cases, a 500-base-pair overlap at the end of a fragment is sufficient to determine that a particular piece of DNA belongs on a particular chromosome."

    Actually, you may want to check yourself there. Using sound waves to break up chromosomes is just fragmentation using sonication. Whether this is a sonicated fragmentation or an enzymatic process really doesn't matter... they are still really just shotgunning and assembling.

    In general I wouldn't use the investor information as my way of exploring what people are doing. Its the company propaganda. Of course they are going to trump up whatever they are doing. A fuel transfer engineer still just pumps your gas.

    Celera received a lot of capital to buy a lot of machines (sequencing and computers) to brute force the project faster than the public projects could. There isn't anything wrong with that. Venter is known in the community as a great salesman, not necessarily as a great scientist.
