Subclassing and Instantiation - Brainchilds of God

Subclassing and instantiation are features of modern object-oriented computer programming languages. The efficiency of this methodology allows the programmer to reuse common code to define new objects. When defining a new object, instead of reinventing the wheel, the new object can inherit properties from an existing object, leaving the programmer only to define the new object's unique aspects. For example:

Basic Object: House
Its properties:
  • Square feet
  • # of bedrooms
  • House style (ranch/bungalow/colonial)
  • Address
  • Year built
Detailed Object: Rental House
Its properties:
  • Inherit all the properties of a house (sq ft, # of bedrooms, etc)
  • Monthly rent
  • Lease start date
  • Lease expire date
Instantiation is the act of taking one of these definitions and applying it to a specific instance (such as describing a specific rental house).

Subclassing and instantiations are truly the brainchild of God. These ingenious features are evidenced in DNA. Often the DNA sequence for a single gene actually codes for multiple proteins. The way this happens is that a RNA copy of the DNA is made. The RNA copy is then spliced at precise predetermined points by various molecular editing machines. However, sometimes whether or not (or where) this splicing occurs is random (50/50 or 33/33/33). Other times the splicing points are weighted, resulting in a fairly consistent ratio of output proteins. Other times the splicing points are completely predetermined, and not susceptible to outside influence. The resulting "family of proteins" that result from this splicing often have related but separate functions. In this way, DNA code is essentially compacted, and then subclassed in its expression. In humans, the majority of proteins are reliant on this mechanism of splicing to get from gene to protein. The amazing thing about all of this is the body's intricate feedback mechanisms that are constantly maintaining these delicate and precisely-controlled balances necessary for life to work.

Online Relationship Calculator for Autosomal DNA

Image
Have you taken a DNA test? Have you looked at the results and wondered what they mean?  What is a centimorgan? Why do you and relatives share them? Is a DNA match your great aunt or your evil twin brother? The calculator chart at the end of this article will help you narrow down the possibilities. Is a DNA match your 2nd cousin, or your 4th cousin twice removed? What does twice removed even mean? The calculator chart will help you visualize the relationship. Simply type in the shared centimorgans (cM) of a DNA match, and the calculator will show you how you're likely related. Here's a picture of the chart with no relationships highlighted. To use this solely as a reference chart, you can download it as a pdf at this link . But to use this chart as a dynamically-highlighted calculator, keep reading... The calculator is based on the Shared cM Project data, version 3.0 dated Aug 2017. This data is a compilation of data from volunteers who input their shared centimorgans ind...

Crime Pays for Ex-Army Manager

Injustice in America takes many forms. Often it takes the form of when justice is not administered by the legal system. "Don't be corrupt when administering justice. Never give special favors to poor people, and never show preference to important people. Judge your neighbor fairly." - The Bible Sometimes crime pays handsome dividends due to ridiculously light court sentencing. This is the story of how Anthony (Tony) Shaw, an Army acquisition manager at the US Army Tank Automotive Life Cycle Management Command (TACOM LCMC) in Michigan, used kickbacks from an Army contractor to bail himself out of personal debt. Tony ends up being the winner, despite being ordered to pay restitution and serve almost 4 years in prison. In an episode that reminds us of the government bailout of AIG, Shaw personally benefited from taxpayer funds that bailed him out of over-leveraged real estate investments in the aftermath of the 2008 recession. Thanks to Tony's light court sentence, ...

Rebedding a whole house dechlorinator

Image
Our new rental house came with a 8x40 Kinetico dechlorinator in the garage, next to a Kinetico dual tank water softener system. The dechlorinator is basically an 8" diameter container that is 40" tall, about 3/4 full of granulated activated charcoal (GAC). As the water flows up from the bottom of the container through the GAC, chlorine is removed from the water. However, the GAC only lasts for a finite time before it needs to be replaced. The specs for a similar dechlorinator say something about 60,000 gallons of water can be treated, but it depends on the amount of chlorine in the water. Since the system is 12 years old, I am going to change out the charcoal bed. The dechlorinator is the black bottle on the left. The two black bottles on the right are a 2-bottle water softener system that works in conjunction with the brine tank on the left. The left bottle shows the 2 water pipes going to the dechlorinator. Release them by pushing up the metal pin in the metal brac...
