  1. Open Source Accounting Agency on Ask Slashdot: How To Get Open Source Projects To Take Our Money? · · Score: 2

    I have tried for years to find a funding source for Axiom, an open source computer algebra project. I checked with the NSF, DARPA, and several companies.

    If I were at a University there would be no problem. I could submit a grant proposal, they send the money to the Provost, he sends it to me, and HE ACCOUNTS FOR IT. The snag in trying to fund open source appears, in every case, that there needs to be trusted accounting. So, the problem is simple. We need a firm whose job it is to receive, disburse, and ACCOUNT FOR, grants and donations.

    That seems simple enough. Set up a small shop (1 person?) who is paid to manage funds, handle taxes, handle banking, handle receipts and invoices. How hard can this be, right?

    IBM contributes to open source through a Linux foundation. I contacted the Linux foundation about setting up an accountant or two to handle the accounting. They never replied. I contacted several people I know at IBM to "donate accounting services" or fund an open source accounting person. They said it was not possible.

    The money would be useful to pay for things like servers (currently costing me about $3000 per year out of my pocket), or fund a conference, or fund developers to attend the usual conferences. It would not be to pay developers.

    Anyway, I have tried to fund this project for nearly 12 years and have yet to be successful. If you can figure out a way to handle the accounting, I'm all ears. Send your ideas to daly at axiom-developer.org

  2. power of 3 rule on Finding a Ready-Made Dev Team? · · Score: 5, Insightful

    This is optimistic at best. Remember the power of 3 rule:
    (where UOW=unit of work (man/month :-) )
        1 UOW = program for yourself
        3 UOW = give it to someone else
              (you install, you copy, etc)
        9 UOW = give it to local group
              (howto, platform change)
      27 UOW = shareware/open source
              (configure/make/make install)
      81 UOW = product
              (real docs, slick UI, support teams)
    243 UOW = business
              (lawyers, CEO, sales, marketing)

    you're looking at a lot more work than you're willing to
    admit. unless it is a trivial application you need to
    understand that writing the program in the first place
    is the easiest part of the whole problem. Teams which
    don't include the original developer are even harder.

    effort to develop software

    1 unit = code for yourself
    3 units = code given to someone else (library probs, config probs)
    9 units = code given to a group (HOWTO, ifdefs, tar-gzip, etc)
    27 units = FOSS code (cvs, mailing list, configure, make, docs)
    81 units = product code (legal, sales, market, packaging, distribution)
    243 units = viable software for 30 years (literate pgms, deep documentation, research, major redesign, etc)

    The effort to get real software to be viable is hard, long term, and thankless.
    How much code are you writing that will be useful 30 years from now?
    What are you doing to make that happen?

  4. Backup using Journal to CD? on Distributed DVD Back-up Solution? · · Score: 1

    I'd like to be able to set up a CD filesystem where the journal is continuously written until the CD is full. The hard drive can be used to buffer the journal until a full block can be written to the CD.

    When the CD is full the journal can be compressed to create a new filesystem on a new CD.

    If we do this then we never have to do backups again.

  6. Re:Windows vs Linux facts on Microsoft Rolls Out New Anti-Linux Ad Campaign · · Score: 1

    Worldcom owns about 75% of the equipment that makes up "the internet". Their data centers house thousands of machines serving "content". Some of the machines are Windows, some are Unix (Linux, BSD, etc). The customer controls what the box runs and what it does. So, in general, you can conclude that this is a "representative sample" of "the internet". Windows machines had at least a 10x trouble report rate over any other kind of server. Worldcom, thru my group, kept a trouble ticket database. We knew exactly what failed, when, and why. Ask Worldcom to perform a query that extracts all trouble tickets for Windows vs all trouble tickets for ALL other reasons (including failed network hardware, power hits, luser errors, etc). Windows will show up at least 10x higher. We used to run this report once a month. (Worldcom no longer exists as far as I know. It is now called MCI. And my department is gone. But the data centers still exist so I suppose somebody is still running the Remedy trouble ticket system). The database goes back at least 5 years. If you want REAL numbers on REAL application loads then Worldcom has the numbers and I've seen them personally. I used to do SNMP, ping, and application specific monitoring using commercial and custom-written applications to monitor every data center and every router, switch, and computer in every data center. If it failed I knew about it first. Based on this experience I would not recommend Windows for server applications.

    On a related note I spent 2 years as a company that did consulting and development work on Windows. We were a Microsoft partner. The idea was that Microsoft would recommend our services to clients. That way we got more business and the client got "Microsoft branding". We got screwed financially on a major deal. We also spent 18 months developing a project using Visual Basic that never was delivered. VB has a memory leak that (a) we never found and (b) MS never bothered to find (we paid $50k I believe for "premium support"). We used DCOM. We were passing messages back and forth between DCOM-based VB objects at the glorious rate of 1 every 24 seconds. A socket version ran in the microsecond range. Based on this experience I would not recommend Windows for client applications.

    Your mileage may vary as these are my personal experiences with Microsoft products. I guess these facts are too small of a sample to consider.

  8. Computational Mathematics on What Applications Will Drive System Performance? · · Score: 2, Interesting

    A certain portion of mathematical research will require computers. The algorithms are hard, run for very long times, and use amazing amounts of memory. When used as a research tools to discover counterexamples or evaluating cases in proofs future mathematicians will use all the horsepower we can generate. Making a computer a useful tool for mathematical research is still an open problem.

  16. Re:Maxima on Open Source Computer Algebra Systems · · Score: 1

    Maxima is quite useful having been derived
    (pun acknowledged) from Macsyma, the mother
    of them all. The best part of working on math
    is that your results are likely to outlive you.
    Maxima has certainly outlived Bill Schelter.
    Maxima is still a useful system for many people.
    Later systems focused on better algorithmic
    development with stronger languages since then.
    But I have yet to see a system that will allow
    me to type in a formula in 2D notation. Nor have
    I seen a system that will allow me to specify
    conditions (like LINE intersects CIRCLE) and
    automatically generate an example. GAP does have
    some lattice output for group theory. None of
    the systems will allow you to easily handle all
    of the textbook problems. Plus it would be great
    to be able to write the theory behind an algorithm
    in Knuth's weave and automatically generate the
    program implementing the algorithm. The ultimate
    in documentation. So there is much beyond Maxima.

    Yes, both GAP and Axiom have well-founded math
    models at their heart. They started out symbolic.
    I do not expect anyone to change religions, umm,
    systems. But we all need to discuss things like
    MathML, common user interfaces, common graphics,
    etc. that are not at the heart of the systems
    and can benefit every system. As to common
    tests I found it very worthwhile to test one
    system by trying others. The tests highlight
    interesting questions such as how and when to
    factor results. I'd also like to see all of the
    free packages available on one CD packaged so
    they could all be run without installation.

    I read the GiNac paper posted at the link.
    Aldor (www.aldor.org) is a language that goes
    well beyond the GiNaC language. It offers Types
    as first-class objects (you can store them and
    manipulate them), symbolic as well as numeric
    evaluation, interpretation and compilation.
    Frankly, though I'm certain to be flamed for this,
    I find that doing computer algebra in C++ about
    like doing division in roman numerals. It is
    possible to do but it is the wrong notation and
    notation is vital to thinking correctly (and
    programming correctly). The closer a language's
    syntax and semantics approaches to the problem
    domain the fewer chances there are of mistakes.

    display, graphing, license etc. I hope to have
    some discussions of math related directions also

    implement them in different ways.

    There is a subtle point here. There will be many
    different computer algebra systems presented and
    they each have a community.I don't expect there
    will be an uber-system that converges them. But
    it is well worth discussing the future directions
    and shared concerns (like a common front-end (e.g.
    TeXmacs)), common test suites, common graphics
    packages. I also expect the license issues to
    be wonderfully warmth-generating :-)

    I was under the (obviously wrong) impression that XP was a single pile that had to include IE. At least that is what the court testimony said. (I know it isn't true). Now we are told that one can build XP from small components. So why can't we unbundle XP and IE (and WMP, etc)? Can I get the parts and build an acceptable alternative pile? Can we get the court to require that XP be shipped as components?
