Billionth Birthsecond
Calculate exact seconds elapsed
Sat January 11 2020  5:58pmComputer

It's probably a guy thing, like watching the car's odometer roll over to 100,000 miles. But, when you think about it, observing birthseconds is really no different than celebrating birthdays. Specifically, the occurrence of one's billionth birthsecond is a rather singular milestone in one's life span. It is the only birthsecond magnitude one can observe with any real appreciation. The next lower magnitude, that of 100 million seconds, occurs when one is just a tad over 3 years old, too young to grasp what such a number entails. The next larger magnitude, 10 billion seconds, occurs at an interval of over 300 years; no chance to observe that event.


Just shy of 32 years of age, the billionth birthsecond could be seen as a sort of coming of age. You're a complete adult now, having typically completed your formal education, embarked upon a career and vocation, fully established, experienced, and capable of assuming leadership while retaining the strength of youth. The moment marking the prime of life. Very close to a hobbit's coming of age at 33 years (ref. The Lord of the Rings).

One could also make an argument for observing one's conceptionsecond (and conceptionday), as that is when one's life really began. We are all about nine months older than our birth age. But it's difficult to determine the exact day, much less the time of day, marking that beginning. Births tend to be more public events than conceptions, and so birthdays and birthseconds are more readily observed.

At any rate, I thought it a worthy and interesting subject for thought. So much so that my first foray into javascript programming was a series of simple calculators that compute the elapsed seconds between two dates and times, and so facilitate (among other things) the observance of one's billionth birthsecond. If you're interested, check it out at ../calc/seccalc.php . If you're 31+ years of age, your billionth birthsecond is near!

CyberJerry software license

Starting a few days ago, the comments area on Jerry's Blog now contains a few words reminding you that your comment is a public work and may be quoted, copied, and shared freely by other people. This is simply an explicit disclaimer of what was always implicit, applicable to pretty much any blog comment on the internet. What's new is that large segments of this website, including Jerry's Blog, are now protected by the Gnu General Public License (GPL). A public license is sometimes called copyleft protection. Conventional copyright means that nobody can copy the work without explicit permission. Copyleft means that the public may freely copy it, but they cannot later claim a more restrictive copyright protection for themselves, even if they modify the work or incorporate some of their own ideas.

This is not usually an important concept for blog articles or comments. It is important for computer software. The Free Software Foundation (FSF) publishes the GPL license with the idea that software ought to be freely available. This is in sharp contrast with Microsoft's propietary mentality that they own their software, and if you want to use it, you gotta pay their high price. You can't copy nor modify nor share it. I hope you know that when you buy a new computer at WalMart or wherever, a large chunk of your purchase price goes to Microsoft for the pre-installed Windows operating system that you can never really own nor control. No, thanks. About 15 years ago, I started running Linux, a public-licensed operating system, on my home computer. More secure, more powerful, more freedom.

So now I'm trying to return the favor, to a small degree. It was also about 15 or 16 years ago that I started writing programs to analyze and solve Sudoku puzzles. This effort has evolved to become arguably the best Sudoku Analyzer on the web, and, since I personally wrote every line of its code, I could certainly claim conventional copyright ownership. So I do. But am now opening up those ownership rights a bit via the GPL agreement, saying that anyone who cares to do so may freely copy and modify my Sudoku software (and even make money with it, if you are more astute than I when it comes to sales and marketing.) What you may not do is claim propietary rights over it yourself, or restrict its use by others. This software freedom applies to my Sudoku Analyzer, and to most other CyberJerry content.

Most, but not all. There remain some private pages, whose contents and encryption techniques will die with me. Likewise I refuse to share scripts that pertain to personal data of blog members or of anyone who submits a CyberJerry feedback form. To see more specific details, see the new CyberJerry license page. You may read the GPL license with all its legalese --> here, or navigate to for more information.

New Math
Fractional-Exponential Integer Math
Thu July 11 2019  10:09amComputer

This old dog is learning a new trick. Specifically, a new math programming technique, called Fractional-Exponential Integer Math. Less complicated than it sounds. It is "a programming technique for storing and computing fractional and exponential numbers without the inaccuracies inherent to floating point numbers. . . It is precise because all numeric values are stored internally as integers."

It began for me earlier this year when I participated in an online math challenge at , my favorite online forum. My (read article)

Data Security
The ironic insecurity of data privacy
Thu November 29 2018  6:40pmComputer

I used to drive a Toyota pickup whose non-functioning ignition switch I replaced with an array of 3 ordinary household toggle switches for: engine, starter, dashboard. Not what you'd call advanced security; anyone could start my truck and drive off without a key (if they could figure out which switch was which.) At the same time, I lived in a farm house with 4 exterior doors, only one of which had a working keyed lock, and that one key was a big skeleton key, too cumbersome to carry about with me. For eleven years I lived a completely key-less life. And never had a problem with auto theft nor home burglary nor vandalism.

Not that I lived in a crime-free area. I'm sure there were (read article)

Blog End
The blog is up and running!
Sat December 2 2017  4:45pmComputer

Contrary to what the first post says, there seems to be no obvious need to write any more about the process of creating a blog from scratch. Oh, you may notice a few minor tweeks since that post: The color scheme now looks more like the rest of the CyberJerry web pages. Have converted completely away from mysql. Made a small collection of my favorite quotes to display at random on the top of the side bar. Mostly, the past two weeks have been spent testing and shaking out bugs, a process that will surely continue.

In concord with the first post, I believe Jerry's Blog has become pretty much what was intended: A simple tool that should run well on a variety of devices, with reasonable (read article)

Meta Blog
A blog article about the blog
Thu November 16 2017  10:00pmComputer

Writing my own blog. No, that doesn't mean writing posts on a new Blogspot or Wordpress blog. It means creating the blog itself - designing server database tables, writing the webpages and blog scripts, debugging, re-thinking, re-working. . . the whole software development cycle.

What 'meta blog' means is that the first few posts of this new blog will probably be about the progress and regress of the above. Blogging about making a blog. And in this case, blogging about starting over again from scratch, on a new hosting server.

To begin, here are my initial design decisions:

  • Simplicity. I have no interest in top-heavy 'features' as characterized in sites such
