Today, Scalent announced Scalent Virtual Operating Environment(TM) (V/OE) version 2.0.

With Scalent V/OE, infrastructure repurposing becomes nearly instantaneous. Changing system function and topology doesn’t require touching physical cables or machines. Instead of spending hours or days reloading software, changing configurations and even moving machines and cables, IT teams can rack once, cable once, then reconfigure repeatedly, in minutes, effortlessly. Failover is automatic, and data center functionality matches the data center schematic — what you see is what you get.

One issue with that approach is that datacenters are heavily silo’ed : the network is administered by a group different from the group managing the storage, or the servers. In the worst case scenario, these functions are even outsourced, either traditionally or leveraging technologies like Amazon S3. Is that something that Scalent is addressing ?

More and more, managing servers, and services, will become a business integration problem, using concepts usually reserved to e-commerce, implementing change management best practices, and leveraging business process automation tools.

Metageek has a nice product, Wi Spy, a combination of an USB dongle and a Windows Software that let you analyze frequencies around 2.4 Ghz :

Wi-Spy™ is the world’s smallest 2.4 GHz spectrum analyzer*. Wi-Spy is perfect for troubleshooting interference from the following devices:

Wi-Fi (802.11 b/g/n)

Microwave Ovens

Cordless Phones

Zigbee

Bluetooth

Wi-Spy is priced at $99. It’s been reviewed Tom’s networking here.

Some open source tools are available for Linux and OSX supporting the Wi-Spy hardware:

Wispy-Raw – A basic dumper from the USB interface to stdout, without RSSI to dBm conversion.

Wispy-Curses – A simple libcurses text-based graphing tool.

Wispy-GTK – A full GTK grapher, similar to the windows graphing tool

According to Libby Sartain, Chief People Yahoo!, in an interview with Guy Kawasaky, the sources of successful candidates are as follow:

Candidate found listing on Yahoo Jobs page—30%

Yahoo employee referred the candidate—30%

Yahoo internal recruiter contacted a prospect (that is, the person wasn’t looking)—20%

Yahoo retained headhunter contacted a prospect (that is, the person wasn’t looking)—2%

Conversion from contractor or temporary—10%

Hot Jobs and other jobs sites—7%

The most interesting piece of information here is the 30% coming from Yahoo Jobs page. It seems to contradict some of the information floating in books, but also seems to point out that the key is to have the resume associated with an existing requisition.

IBM acquires Webify

Today, IBM announced that they are acquiring Webify:

ARMONK, NY - 02 Aug 2006: IBM (NYSE: IBM) today announced it acquired Webify Solutions, an Austin, Texas-based, privately held provider of industry-specific software and services for building service oriented architectures (SOA).

Webify provides what they call Industry Fabrics :

The Webify Industry Fabric is an integrated environment for policy driven sourcing, assembly, delivery and governance of business services and composite business services. It consists of six complementary modules that allows companies to source, provision, deliver, and govern industry-specific business services, processes, content, and events from a variety of internal and external sources.

They have fabrics for the following industries:

  • Healthcare
  • Banking
  • Telecom
  • Insurance

Today, Microsoft announced, along with other vendors, the publication of, or their intend to publish later, a new language to model data center resources and their management in XML. This language is called Service Modeling Language, and is based on Schematron.

As a result of collaboration, the open, industry-wide specification defines a common language for expressing information about IT resources and services. Called the Service Modeling Language (SML), the specification enables a hierarchy of IT resource models to be created from reusable building blocks rather than requiring custom descriptions of every service, thus reducing costs and system complexity for customers. The group plans to submit the draft specification to an industry standards organization later this year.

This language is intended to replace Microsoft’s System Definition Model

Today, HP announced their acquisition of Mercury Interactive.

HP today announced that it has signed a definitive agreement to purchase Mercury Interactive Corp., a leading IT management software and services company, through a cash tender offer for $52.00 per share, or an enterprise value of approximately $4.5 billion, which is net of existing cash and debt.

This comes after the acquisition of Peregrine in September 2005.

HP portfolio in the Business Service Management, Enterprise consolidation and optimization is now very comprehensive.

Interesting piece of information from this post on PushToTest :

Caucho told developers that they are seeing an astonishing 4 to 6 times performance improvement over the C-version of PHP. Quercus runs with JVM thread safety – something not available to PHP developers today – to enable things like database connection pooling in a threaded environment. Quercus is expected to ship by December 2006.

Here is another mention of this information on ServerSide :

Apparently, the PHP pages are compiled in the background to byte-code, and the resulting performance is six times that of Apache mod_php!

And this post is generating quite a few comments.

A more definitive source of information is available on the caucho forum where some actual numbers have been posted :

Test Name Resin/Quercus Apache 2.0/PHP 5.0
file_1k 6341 ops 3255 ops
file_1k (10 clients, 16 keepalive) 13186 ops 6154 ops

and, with PHP acceleration :

Test Resin/Quercus Apache/PHP/eaccelerator

drupal 46 ops 43 ops

wiki 30 ops 17 ops

With more tuning, the PHP performance might match the Resin/Quercus ones, but it should be a wake up call to all the Java detractors. Java IS NOT SLOW !

In a recent post titled OMC Should Drive a New Systems Management Taxonomy, the author makes the case for the creation of a taxonomy to classify and describe the various open source projects that the Open Management Consortium (OMC) is hosting.

This is a good idea, but I would have the following remarks :

  • There should be an agreement to use a common glossary, like the version 3 of the ITIL Glossary.
  • A common functional model for the OMC should be developed, and each product mapped to it, or classified in the taxonomy. I’m referring to a model like the one I developed, and published in this post. It might not be perfect, and could be definitely improved and adapted, but I found it to be a good base.
  • The taxonomy should be created based on a data center management operational model, aligned with customers functional requirements.
  • When this mapping is done, the consortium should drive a integration strategy to resolve overlaps and gaps, as well as defining a common integration and interoperability framework. Quite often, open source projects are duplicating efforts because there is no overall strategy, or agreements between projects, and since there is a limited supply of community members, they should be directed to maximize their impact.

So, to answer the questions in the post :

And so I’d like to get a read from the other members of the OMC, and from visitors that may not yet be participants (you can join by going to: http://open-management.com/join/) as to whether they: A) agree that such a taxonomy is needed and, B) will commit to using it to describe their projects, assuming that we establish in advance the rules for discussing and deciding what the taxonomy would be.

A : yes, the taxonomy is needed, but see my points above.

B: I cannot commit since I do not represent a member of the OMC, but this requirement is making a lot of sense.

I hope that the discussion on this taxonomy or functional map will be performed in an open forum, and I would happily contribute.

Saturday was spent at New Brighton State Beach near Capitola. While it was a very nice day, it started with quite a bit of fog. The light was very nice, and the resulting picture looks like chinese painting, … well, almost :-)

I stumbled on Rich Burridge’s weblog post about book statistics, it has some scary numbers :

Who is Reading Books (and who is not)

One-third of high school graduates never read another book for the rest of their lives. Many do not even graduate from high school.

58% of the US adult population never reads another book after high school.

42% of college graduates never read another book.

80% of US families did not buy or read a book last year.

70% of US adults have not been in a bookstore in the last five years.

57% of new books are not read to completion.

58% and 42% ?!?!? how is that possible !
