The Lunatic’s take on Daylight Savings Time

Sunday, 4 November 2012 08:24 by The Lunatic
Twice a year, once in the spring and once in the fall, we move our clocks either forwards or backwards to accommodate the change in Daylight Savings Time. And twice a year, there are the requisite news articles written about Daylight Savings Time, explaining to everyone why we go through all this hassle. Then there are the cutesy and often misguided Facebook posts with statements like: “only the government would believe that you could cut a foot off the top of a blanket, sew it to the bottom, and have a longer blanket.” (which is what prompted me to write this particular article in the first place!) So let’s get to the bottom of what Daylight Savings really is. First of all, however, we have to understand what midnight is. That’s right: midnight, the time that we’ve decided each day should start. Technically, midnight is the time that is halfway between sunset and sunrise. It’s simple enough, but that definition needs some clarification. As the Earth revolves around the Sun, the Earth’s tilt causes daylight hours to shift with the seasons. A better definition is that midnight is the time that is halfway between sunset and sunrise, at the equator, on either the fall or spring equinox (the only two days of the year when the sun is directly overhead at the equator). Now we’re getting somewhere, but there’s one more wrinkle in this definition. You see, the Earth is just over 24,000 miles around and More...

I'm A Believer!

Friday, 27 April 2012 07:39 by The Lunatic
There is a pervasive and somewhat lopsided tendency in our society to separate fellow humans into the categories of being either “believers” or “non-believers”. The not-so-subtle implication is usually that there is something wrong with you if you are a “non-believer”. Let’s play a little game; I’ll take the position that there really is something wrong with non-believers. But first, let’s swap the traditional idea of who is a believer and who is a non-believer. For example, if I have a ball in my hand and I hold my arm straight out from my body and I drop the ball, I believe that the ball will always fall “down” – towards the ground. In our game, non-believers are the people who will say that god can make the ball go up, or sideways, or turn into a flying cheeseburger and flap its wings at the moon. If we get all the non-believers on Earth to PRAY really hard, and ask god to make the ball go “up” when I let go of it, I still believe it will go down. If you ask a believer why the ball will go down instead of up, the typical explanation you will get is that “gravity is a force that attracts two objects proportional to their mass”. In general, the answers that believers give you will have something to do with gravity, and the answers will be relatively consistent on average. Without some external physical force (a blast of air, or someone swatting it with a tennis racket for example), believers will say that the ball will drop “down” even if you conduct the experiment hundreds of billions of times, as long as the Earth and the ball have mass. However, if you ask all the non-believers why praying to god doesn’t ever change the fact that the ball goes down when dropped, you will get a bunch of different, inconsistent, and largely contradictory answers. One of the answers you might get is that ‘god doesn’t work that way’. I love that answer, I hear it all the time. I keep asking all the non-believers how god does work, and no one really seems to know. ... [More]

The Worst Investment Ever Made

Tuesday, 15 March 2011 03:54 by The Lunatic
The height of the “dot com” boom was a pretty crazy time for investors; venture capitalists were investing huge sums of cash with any entrepreneur who could type the word “internet” without using a spell checker. People made some really BAD investments and only a few of the startups from that period are still operating today. But there’s one deal that really takes the cake. This acquisition was so absurd in its reasoning and so insidious in scale that I’m surprised the story hasn’t been made into a Hollywood feature film. Let’s back up a few years, to 1996. This was the year that yours truly joined a small internet startup called VXtreme, an early pioneer in streaming video on the web. VXtreme had actually developed a viable technology and we created what was arguably the best streaming video platform (codecs, encoder, player, server) in the world at the time. Remember that in 1996, people were connected to the internet with 28.8Kbps modems – or if you could afford it, you might have one of the spanking new 56K modems.  Whoo-Hooo! Blazing fast internet it was, indeed. Delivering real time streaming video over such a connection was problematic at best – but it was SO exciting to see a media player embedded in a web page, rendering real time video with a resolution of 160x120 pixels at a whopping 15 frames per second refresh rate! We were truly on the bleeding edge. In just over ten months, we built the company, produced the product, engaged a bunch of high profile customers, and sold the whole thing to Microsoft for about $74 Million (and to set the record straight, I was not one of the founders or shareholders – just a “late hire” marketing manager, with options that were only worth about 1/10th of 1% of the company). It was a fair valuation for VXtreme.  Our technology was merged in with the “NetShow” product that Microsoft had been struggling with, and the platform was eventually renamed “Windows Media”. Even today, the Windows Media Player, Windows... [More]

The Evolution of god

Wednesday, 24 November 2010 00:19 by The Lunatic
The following article was written under invitation from the CommonGroundGroup, a website put together by some members of the Baha’i faith, for discussion of the common areas of agreement between science and religion. They seek to include alternative views and promote open discussion on topics of science, religion, and philosophy. I appreciate the invitation to contribute an article which is diametrically opposed to most of their normal postings. I love evolution. Just as biological evolution creates new species, information and knowledge and technologies also evolve – and in a very similar manner. Take the microprocessor that is running the computer on which I’m writing this article, for example. The electronic microprocessor isn’t the brainchild of a single brilliant engineer who just created it one day, without any prior information or knowledge. All modern processors are evolutionary offshoots of the Intel 4004, introduced in 1971. It was a huge breakthrough, but that milestone could never have come about without the invention of the transistor and the many simpler integrated circuits before it; and the core processing logic was built upon the mechanical and vacuum tube computers which evolved over the fifty years before that. None of these would have been possible without a working knowledge of electricity, magnetism, chemistry, and physics – the secrets of which have been slowly uncovered, bit by bit, for hundreds (thousands!) of years. Evolution tends to go in fits and starts, especially in the early stages. There are the agonizingly slow changes that take millennia – the spinoff of one species to another for example, or the adaptation to environmental changes that all early life went through as the Earth cooled; for almost half of the 3.5 billion years that life has existed on Earth, there was nothing more complex than single cell organisms. But then, occasionally, some big event comes around More...

The Crazy Price of Video Cables

Wednesday, 15 September 2010 15:02 by The Lunatic
In years past, when you purchased a VCR or a DVD player, it would come with a video cable so that you could go home, connect your new player to your TV, and immediately start watching.  It was usually a cheap combination audio/video cable – not very sturdy, but it would get the job done. If you purchase a new Blu-Ray player today, however, you will find that not a single cable is to be found in the box. A high tech Blu-Ray player should really should at least come with an HDMI cable (High Definition Multi-media Interface, the preferred method of connecting any HD video source to a digital television).  A decent quality cable costs less than fifty cents to make. Are the manufacturers just getting cheap?  Trying to cut corners? Nope.  They’ve stopped including cables because More...

The Future of Communications

Monday, 26 July 2010 17:43 by The Lunatic
  I just got back from a one-week excursion to Washington DC. I had two objectives for this trip: buy a car, and find a house to live in (since we are moving back to the USA next month.) Buying a car and selecting a house to lease in one week is difficult enough – but it’s even more problematic when the rest of your family are on another continent. I needed to keep in contact with my wife and kids three or four times a day as I scouted out different neighborhoods and looked at houses.  To make matters worse, I didn’t have my cell phone with me since my basic calling plan (discussed below) doesn’t have international roaming. So it was Skype to the rescue!  Calling home to Switzerland on Skype is only 2.1 cents a minute, and if the internet connection is good, the voice quality is indistinguishable from a regular phone call. The problem, however, is More...
