Bush, Cheney, Halliburton, Tort Reform and Asbestos

The Great Confusicator (Obsfucator?) has spent a lot of time stumping for Tort Reform this week. His primary example has been firms hit by Asbestos lawsuits.

I wonder if this is because Halliburton subsidiary KBR ended up going into Chapter 11 fighting an Asbestos lawsuit? (More here and here)

Wonder why no one is talking about this…or does the Washington press corps have a short memory?


I stand corrected — CBS MarketWatch does mention Halliburton in an Asbestos story. Right at the very bottom.

Snow Hits Vancouver Island

Samantha and I hail from Victoria, BC, on Vancouver Island, the largest island off the Pacific Coast of North America. It is blessed with a mild mediterranean climate, year-round.

Except now.

Apparently they are having a winter storm that has dumped more snow on the area than we have seen in Massachusetts this year.

Have fun!

NY Times to charge?

Dan Gillmor mulls over the thought of whether the NY Times will charge for its online service.

My answer is: NO.

I am increasingly angered by newspapers that make their sites more and more irrelevant to me by hiding behind subscriptions and registrations. Do they need my marketing information?

If they will only make their online content available to subscribers, why have a dead-tree edition? Or vice-versa?

Online news is how the majority of my generation and younger get their information. Lead, follow, or get offline.

Jeremy’s Final Word on the Firing

Jeremy has one final swing at the termination of his employment.

My take is that the response of HSC is very typical of any large firm who has been caught in a very public and almost untenable situation. And that they chose to discuss a personnel issue at all makes me see them in a very bad light. HR should know about the confidentiality rules in Canada.

The response of former employees also is typical of the response of full-time, politically-tenured employees to contractors in all organizations. I have seen this in almost all work cultures — "How dare he smear our company’s name; and he was just a contractor anyway".

Glad Jeremy has moved on; I will now drop the topic.

New GrabPERF Features

Added two new features to the GrabPERF system this morning.

  1. Display the Arithmetic and Geometric Mean by aggregated hour. This uses the datapoints in the ‘data’ table, which reaches back 10 days.
  2. Display the Success Rate by aggregated hour. Uses the same data as above.

These are attached to each individual test screen.

Have fun!

Thoughts on Web Performance Excellence

In writing the last post, I was thinking about what factors go into making the Web performance of a site “excellent”. What defines in the minds of the sites users/customers/visitors/critics/competitors that the performance of a Web site is excellent?

These are usually judged by the standard factors:

  • Responsiveness
  • Availability
  • Traffic
  • Reliability
  • Security
  • Clarity

But within the company itself, how is the performance of their Web site judged to be excellent?

Right now, most people use the external metrics mentioned above to determine excellence. However, it must be remembered that there are two other critical factors that need to be considered when managing a large IT infrastructure.

  • Ease of Management. This is a metric that is often overlooked when determining if a Web site is excellent from an internal perspective. Often it is simply assumed that running a large IT infrastructure is incredibly complex; in most cases this is true. However, is it too complex too manage efficiently and effectively? How much time is spent finding the cause of problems as compared to resolving them?
  • Cost of Operation. This is always a big one with me. I look at sites that are trying to squeeze as much performance and availability out of their sites as they can. At some point, the business has to step back and ask, “How much does another half-second of speed cost us?”. When this context is placed around the “need for speed”, it may open a few eyes.

When this two critical internal factors are combined with the raw external data that can be collected, collated and analyzed, some other ideas come to the forefront as KPIs in Web Performance Excellence:

  • Cost Per Second. The cost of a Web site is usually only calculated based on the negative metric of how much it costs when the site is down. Well, how much does it cost when the site is up? Can that number be reduced?
  • Revenue By Speed. Which customers spend the most on your site: LAN, home-broadband, or dial-up?
  • Person-hours per day. How many person-hours per day does it take to manage your Web site?
  • True Cost of Performance Issues. When there is a performance issue, the cost is usually associated with lost revenue. Reverse that and ask how much did it cost in time and materials to resolve the issue.

The creation of new Web performance excellence metrics is crucial if companies truly want to succeed in the e-business arena. Business management has to demand that IT management become more accountable to the entire business, using metrics that clearly display the true cost of doing business on the Web.

Heavy-Tail Distribution in Web Performance Data

I found a great example of a Heavy-Tailed Frequency distribution in my performance data today.

heavy-tail-data-apr132009

This clearly shows how data in the wild can be distributed in a non-normal fashion. In this case, there is a very heavy weight on the end of the tail, not simply a few straggling outliers.
It has become very unusual to find sites that exihibit this degree of heavy-tailed behaviour  over the last year. When I started in this industry, this was more the norm than the exception.

Jeremy Wright Adds More On His Firing

Jeremy has added more on his firing (here).

I am going to burn my bridges with more than a few potential Canadian employers by saying that this does not surprise me at all from the Canadian management mentality. In some ways, it is still stuck in the Victorian era: paternalistic and vindictive. My interviews with Canadian companies have always left me going, “I don’t want to work for them!”.

Why? Because the HR Teams at Canadian companies are designed to remove critical thinkers and free spirits. I have yet to find a Canadian company of any size where innovative thought and inventive concepts were allowed to flourish.

I would name some examples, but that would get me into even more hot water.

Corporate Canada — and Corporate America, for that matter — has to accept that people talk about companies: to friends; colleagues; and the world. Blogging just makes that more global.

As Jeremy states, companies need to understand that blogger and companies have to agree where the line is, and soon.


Hmmm…more than a few hits on this article from HSC, Jeremy’s former employer.
