Femur | 16 years ago | on: How to assert that your SQL does not do full table scans
The modern Oracle uses a Cost-Based approach wherein the query optimizer will attempt to perform the lowest-cost opration to satisfy the query. If that means performing a full-table scan as opposed to utilizing an index, then this is what will be done. Statistics, data histograms, parameters (such as OPTIMIZER_ INDEX_COST_ADJ) all come into play.

I sing duets, dance tangos, and play concertos.
I cook banquets. I wheel, make deals, and strike bargains. I purchase fruit in large quantities. I partake and imbibe. I articulate, expound, and drive home the point. I maintain a strong moral fiber and act with integrity.
I forge trails and bushwhack through jungles. When I am not walking, I am running. I sail and drive and fly and ride and crawl.
I write encyclopaedias. I learn, study, forecast, ponder, and calculate. I know the answer.

"This section shall not apply in the case of an individual who pursuant to an arrangement between the taxpayer and another person, provides services for such other person as an engineer, designer, drafter, computer programmer, systems analyst, or other similarly skilled worker engaged in a similar line of work."

In Kurzweil's talks he often expounds on the high predictability of technological progress (price and power of computing, etc). He does not so much cover how humans will use this tech.
Im sure that iPod Nano's (or equivalent) could easily have been embedded or sewn into clothing or hats for years now. Speech-to-text is available now and I use it in Google Voice all the time. It's a matter of choice in this case, not the technology.

Edit: I may have jumped to conclusions; the individual on reddit may have very well stolen your comment in which case my accusation is invalid.

Houston is generally a more conservative city than SF. Overall, I feel that Houston is generally well run.

Of course, the old metalink was also poorly designed. I guess you could say that it just went from bad to worse.

Femur | 16 years ago | on: Why Saving is for Suckers
The author ignores one very important concept faced by individuals: risk. It would be just plain stupid for most people to keep an emergency fund in the stock market. At the same time, it would also be stupid for a person to keep long term investments in a low interest savings account.
It would be a mistake to conflate these two goals while ignoring risk.
There are MANY factors in play. Stats, parameters, histograms... it really depends.
