If you want to start the drive in standby:

sdparm –command=start /dev/sdb

To clean standby mode flag:

sdparm –clear STANDBY -6 /dev/sdb && sdparm -a /dev/sdb

Oracle has failed in its attempt to enter the Linux market. Our recent survey of Oracle database customers reveals that only 1 out of 32 customers currently uses Oracle Unbreakable Linux. This one customer also commented that “support is terrible, it is difficult to get an answer to my problems, Oracle’s agents never understand my company.” The survey reflects a very low penetration rate in the 2-year period since Oracle unveiled Unbreakable Linux with much fanfare, including live penguins running around onstage with Larry Ellison. Resellers continue to characterize Unbreakable Linuxas a failure because Oracle ultimately cannot control the future direction of RedHat Enterprise Linux, upon which it is based.

While the Street has expected Unbreakable Linux to severely impact Red Hat, its failure ironically serves as a proof-point of the underlying defensibility of RedHat’s business model. In fact, in the two years since Oracle introduced Unbreakable Linux, Red Hat’s billings have grown at an average rate of 31%–representing clear market share gains.

Subject: Why I am no longer working on Mercurial
Newsgroups: gmane.comp.version-control.mercurial.devel
Date: 2005-09-30 21:40:55 GMT

As I mentioned the other day, I will not be contributing to Mercurial
development for a while.  Several people have asked me why.

At my workplace, we use a commercial SCM tool called BitKeeper to
manage a number of source trees.  Last week, Larry McVoy (the CEO of
BitMover, which produces BitKeeper) contacted my company's management.

Larry expressed concern that I might be moving BitKeeper technology
into Mercurial.  In a phone conversation that followed, I told Larry
that of course I hadn't done so.

However, Larry conveyed his very legitimate worry that a fast,
stable open source project such as Mercurial poses a threat to his
business, and that he considered it "unacceptable" that an employee of
a customer should work on a free project that he sees as competing.

To avoid any possible perception of conflict, I have volunteered to
Larry that as long as I continue to use the commercial version of
BitKeeper, I will not contribute to the development of Mercurial.

As such, Mercurial can stand entirely on its own merits in comparison
to BitKeeper.  This, I am sure, is a situation that we would all
prefer.
