Deducing purpose where there is none

There is so much that I respect and admire about the American astronomer Carl Sagan. I have enjoyed a few of his science books and absolutely loved his 1980 television series Cosmos: A Personal Voyage, which he narrated and co-wrote.

Carl Sagan: A Universe Not Made For Us

I recently discovered this 10-minute video of him contemplating our views of the universe and how we’ve historically relied on religion to provide understanding. In particular, I like his closing words:

“There is in this universe much of what seems to be designed. But instead, we repeatedly discover that natural processes — collisional selection of worlds, say, or natural selection of gene pools, or even the convection pattern in a pot of boiling water — can extract order out of chaos and decieve us into deducing purpose where there is none.

The significance of our lives, and our fragile planet, is then determined only by our own wisdom and courage. We are the custodians of life’s meaning. We long for a parent to care for us, to forgive us our errors, to save us from our childish mistakes. But knowledge is preferable to ignorance. Better by far to embrace the hard truth than a reassuring fable. If we crave some cosmic purpose, then let us find ourselves a worthy goal.”

Carl Sagan: Pale Blue Dot,

The above video reminded me of another that I’d like to share.

WSUS Update Classifications

For some reason, I have a difficult time finding the brief descriptions of the nine update classifications that you can use to filter the updates you get from Microsoft Updates, so I thought I’d list them here. The source is Microsoft’s “Using the WSUS 3.0 SP2 Configuration Wizard” TechNet article:

Critical Updates: Broadly released fixes for specific problems addressing critical, non-security related bugs.

Definition Updates: Updates to virus or other definition files.

Drivers: Software components designed to support new hardware.

Feature Packs: New feature releases, usually rolled into products at the next release.

Security Updates: Broadly released fixes for specific products, addressing security issues.

Service Packs: Cumulative sets of all hotfixes, security updates, critical updates, and updates created since the release of the product. Service packs might also contain a limited number of customer-requested design changes or features.

Tools: Utilities or features that aid in accomplishing a task or set of tasks.

Update Rollups: Cumulative sets of hotfixes, security updates, critical updates, and updates packaged together for easy deployment. A rollup generally targets a specific area, such as security, or a specific component, such as Internet Information Services (IIS).

Updates: Broadly released fixes for specific problems addressing non-critical, non-security related bugs.
