IT is like music to my ears
When I'm not wearing my CTO hat, I spend a lot of time thinking about
music — listening to it, playing it, and reading about it — which
causes me to see IT operations in distinctly musical terms. Managing
IT often seems like managing the affairs of a rock band, with its
curious mix of creative talent, volatile personalities, and lots of
gear. When a sysadmin brags about the blazing throughput of the Linux
server he just built, it feels a little like listening to Spinal Tap
guitarist Nigel Tufnel proudly describing his amp that "goes to 11."
The most useful IT/music analogy I can make is a reference to an old
truism about what makes good musicians great. Good musicians deliver
inspired performances while hitting the right notes and keeping time,
but truly great musicians know when not to play. In IT, applying this
philosophy means knowing when to remove yourself from a process, step
out of the spotlight, and let someone else take the lead.

Looking
for Indemnification While Linux Sales Double
Little doubt exists; a legal cloud hangs over Linux from infringement
claims of the SCO Group, Inc. In spite of that cloud, Linux server
sales grew 56.9 percent in the first quarter of the year. Linux sales
in 2004 follows six consecutive quarters of double-digit growth for
the free operating system during unprecedented legal attacks from
SCO over the same period.
Linux success helped push all server growth to 7.3 percent according
to IDC's Worldwide Quarterly Server Tracker. The contradictions of
sales increases and legal uncertainties bring into question the degree
of concern people actually feel about SCO's legal claims. One might
say, if the defendants of the SCO suits don't see concern, why should
I?

Using
802.3af (Power Over Ethernet) as a Sysadmin Tool
Although we're used to thinking of Ethernet cabling as a medium for
data, the wires can also be used to deliver a useful amount of DC
power to connected devices. This is called Power over Ethernet (PoE).
In addition to saving money on installation, PoE can sometimes be
a useful tool for sysadmins. Here's how.
Power Over Ethernet: A Little Bit Of Background
Similar in principle to the way that the wire pair that carries your
POTS (Plain Old Telephone System) telephone signals into your house
also carries enough juice to power the phone's core innards of headset,
dial, and ringer, PoE delivers DC power (up to about 15 watts per
wire) over standard Ethernet cabling (CAT5 and better, and some CAT3)—enough
to power a growing number of commonly-used useful devices.

TKCluster
Linux has shown a lot of growth in the area of data-centric, high-availability
clustering. Most admins are already familiar with computational clusters,
known loosely as Beowulf clusters, which are implemented in the form
of MPI, PVM, LAM, MOSIX, and other process-sharing and process-distributing
technologies. There are also "Web service clusters", such as those
distributed in years past by TurboLinux and others. These were typically
groups of similarly configured servers that used DNS and round-robin
IP address tricks to give the illusion of Web server high-availability
to end users.
Cohesive operation between the nodes, however, was still only achieved
through a shared-storage medium, such as Fibre Channel or shared SCSI,
which are prohibitively expensive for small businesses, or proprietary
cluster hardware and software, which is also prohibitively expensive.
A database engine that serves a Web cluster must still itself be clustered
to achieve true high-availability. Application-level high-availability
tools (such as the MySQL database engine) that transparently replicate
themselves between servers, are also being used to provide some level
of redundancy.

China
disowns IPv9 hype
Evidence is growing that IPv9, hyped up the widely-adopted foundation
of a next generation Internet infrastructure in China, is really a
marginal project backed by few even in China.
Reports from China this week about widespread adoption of the previously
unheard of Internet protocol have created bewilderment and something
approaching a diplomatic incident in the sysadmin community.
