    There isn't a real arguement at all: it's recently come out that a/the objector to MySQL going to Oracle was Microsoft. I strongly suspect it's a put-up job, astroturfing the EC to hurt a competitor.

    The objection to Oracle owning MySQL came in part from Microsoft, a competitor, and other as-yet-unknown parties. Wanna bet it's just a way of throwing a wooden show in Sun's gears, for all the flack MS used to get from them?

  7. Re:Not for a (looooong) while on Will Books Be Napsterized? · · Score: 1

    For books like "Using Samba", you can have the electronic form of the whole book for free. Nevertheless, people still send money to O'Reilly for the dead-tree format.

    Back when we did the first edition, we found that even hard-core electronic-everything folks wanted the physical edition. You could read it in the bath or the subway, make notes in the margins, and read a page with two fingers stuck in at two other pages you were referring to. And the printed form was small enough to hold easily in one had, something that wasn't true if you printed it yourself on 8 1/2 x 11 paper.

    Conversely, the electronic form was easier to search, which helps if the word you want isn't in the index. You can stick a copy on your latop, for whenever you're away from your bookshelf. And you can print out excepts to leave with customers so they can figure out what the heck you just did.

    So both forms are valuable, but for different things.

    E-books are horribly primitive as of the moment, and not exactly waterproof, so I'm seriously doubtful that they will compete with paper books for long time, if ever. Instead they will complement them, just like the copy of Using Samba on my laptop complements the copy on my bookshelf.

    The first is trivially true: If I've been using Oracle, I probably want a service contract, and would buy the "enterprise" MySQL.

    Monty's second point is puzzling: he seems to have information the the EC normally keeps very close to their chest.

    Monty Program AB has certainly recommended divestment, but since they're doing the current fork I'd have to lump a flat claim that Oracle has refused to divest in with the rest of the lobbying by Oracle competitors including SAP AG and Microsoft Corp as possible FUD.

  14. I'd FUD this too, if I was an (evil) competitor on Oracle To Sell Sun's Hardware Business To HP? · · Score: 1

    Sun's competition is pushing real hard to get customers to defer or cancel Sun sales in favor of their products. One way is FUD, suggesting that, for example, Oracle will cancel the Sun hardware lines. I see this as an another FUD effort, suggesting that H-P, who only buys companies up to cancel their hardware, would buy Sun from Oracle.

    Another tactic is to start rumors that the U.S. DoJ and the EU will have to investigate.

    The longer they can get people to defer Sun purchases, the better chance they have of selling their products in lace of Sun's. So expect lots more rumors to be "placed", with slashdot being a target for this kind of FUD. P.--dave

    I absolutely agree with your last sentence, although I see most of the Sun efforts to be toward reducing the latency, by not making the bus wait in between the request and the reply. That speeded up small memory transactions a lot, targeting the low speed of locking operations that have to go to memory and/or achieve global cache consistency.

    I would like to see latency bettered, too. To me, it's at least an order of magnitude high.

  23. Re:Bad deal for both companies on DOJ Gives Oracle Approval To Buy Sun · · Score: 4, Interesting

    My leaky memory says that 40% of Oracle's income (profit?) comes from Oracle on SPARC, and another 20% from Oracle on other Unix.

    If IBM had bought Sun and phased out SPARC like they did Sequent, then they'd probably own 50% of Oracle's market.

    It's far better for Oracle to buy their own hardware supplier than depend on others: the Sequent was highly optimized for Oracle performance, and then disappeared in a little puff of greasy smoke when IBM bought it and shut it down in favor of Power. That's got to have been painful!

    As other commentators have pointed out, Oracle is heavily invested in Java, and sees MySQL as a "channel" that brings them customers. You note that Oracle invested in improving the performance of the transactional engine that MySQL uses instead of shutting it down...

    I suspect Sun was a perfect fit: it complemented the things Oracle needed, and didn't have any important products that compete directly. Win-win.

    That in turn could be good for me, as I'm a capacity planner & performance guy, working mostly on large systems, like the ones Oracle and Sun customers use.

    Actually the advantage is a fast backplane, not the memory. You may remember they bought the rights to the Cray asynchronous (really packet-switch-like) backplane quite a number of years ago, and have been expanding on it since.

    It's easy to build a fast chip if it never has to maintain cache-consistency with anything off-chip. If it has to stay sane, even with only 64*4*2 = 512 threads banging on the same memory range, it not only takes an expensive bus, but it's also memory-transaction-rate limited.

    That's why you read about transactional memory in Linux Weekly News: we all need it, SPARC and Intel both.
