Fitness Tracking

One of the biggest difficulties I have getting fit is the lack of metrics on progress. I have no way of knowing whether or not a workout is effective or whether or not I'm making good use of my time. Fitness trackers are available now although most of them only track footsteps which to me is useless (maybe I'm wrong).

In addition I also have a terrible time getting quality sleep. I wish there were a device that could monitor and debug my sleeping difficulties.

Estimating CPU Power

This is a basic outline for determining minimum CPU core, core mix and core frequency and also minimizing power consumption.

Define High Level Use Cases
First define what tasks your CPU will perform. This will usually be something like a certain number of computations per second, minimum frame rate in a game or video play back or web pages served.

Determine Design Constraints

Building a Home Theater: Things to Consider

Target: These days Blu-Ray offers very high fidelity video with multi-track audio.

This is a checklist of things to consider when building your home theater.

Perfecting the CD Rip

You can rip any CD with just about any software and any drive and get a good, listenable copy of the original. But how close is it to exactly what the studio recorded? And can you tell the difference? Who knows, but let's discuss how to produce the perfect rip.

Philosophy vs Technology

This is a huge subject I'm not about to take on completely, but I've had it on my mind for some time since seeing a documentary about the Logical Positivists and reading some of Husserl's work.

Obvious questions:

Beersworth Chart

How much are you really drinking? How much alcohol is in that 7oz pour of stout? Did you just hammer a bomber of IPA and want to know what you've gotten yourself into? Use this chart to find out.

1 beer = 12oz @ 5%

(And just for kicks a 16oz pour of Firestone-Walker Union Jack is also added.)

I Don't Believe in Dark Matter

I think dark matter is an awful explanation for an explanation of the "missing matter" problem. We can't see it? Oh it must be invisible?!? Lame.

I have another idea and it is much more simple. It starts with the basic question: What if the gravitational effects come from beyond the edge of our universe?

A couple of points of evidence and a concept appropriated from astronomy:

Analysis of Hard Drive Latencies and its Impact on Performance.

I originally wrote this in college, a couple of years ago. I wrote how solid state drives would improve computer performance and wanted to update this article now that multi-core processors and solid state harddrives (SSD) have become a reality.

Green Living

Just some notes I made on green living. Not particularly interesting, but I wanted to keep them so I might as well publish.

Goal: No impact living, which means living in an environment without having any impact, positive or negative. This also means energy and oil independence and foreign independence. This has the benefit of reducing pollution and smog, mitigating global warming, reducing habitat destruction and creating a more robust economy.

Solution: Reduce energy usage, waste, consumption, be a selective consumer, and use only renewable resources.
