Lucky Earth

A random sample of the collection of improbable and mutually exclusive events that led to our emergence here on this rock.

If the Sun formed in a region with less or different gas contribution the Earth would likely have an ammonia Ocean instead of a water one.

If the proto planetary disk didn't have so much accreted asteroids and comets proto Earth would not have gained so much water and would likely be dry.

If the Earth didn't accrete as much dust as it did, we'd have a smaller radius and likely not have a radioactive active core..the active core is what produces our magnetic field and thus protects us from the deadly solar wind of the sun. Life would not exist.

If the proto Earth had not been struck by another body just before 4.4 billion years ago, the planet would not have reconstituted into the present Earth 2 + moon system. Without the gyroscopic stabilization of the moon against the distant but influential gravitational nudges of Jupiter we'd have no predictable seasons and life would have no way for evolution to consistently emerge complex life forms...Earth would have stayed a planet of bacteria.

It goes on an on...if the Anoxic transition didn't occur, if the planet was not subject to the great extinction of 240~ Mya that cleared the landscape for the emergence of the dinosaurs...if the KT asteroid didn't hit 65 million years ago and clear the way for the rise of mammals and grasses and Magnoliaphylum...it goes on and on

Each one if it didn't occur would eliminate us from the rock...the Universe doesn't care about our presence here and the fact that we are finding so many worlds now, in so many states of pathology underscores this fact. Swollen giants mere millions of miles from their parents stars, Giants at impossible distances away from their stars and soon rocky planets in all states of formation thanks to Kepler Sat. If there is a God it surely lost track of our development in the endless list of billions upon billions of planets that exist in this Galaxy in various states of formation of life in a visible Universe of over 100 billion Galaxies...the mind simply boggles.

Highly targeted Cpg vaccine immunotherapy for a range of cancer

Significance?


This will surely go down as a seminal advance in cancer therapy. It reads like magic:

So this new approach looks for the specific proteins that are associated with a given tumors resistance to attack by the body's T cells, it then adjusts those T cells to be hyper sensitive to the specific oncogenic proteins targeted. These cells become essentially The Terminator​ T cells in the specific tumor AND have the multiplied effect of traveling along the immune pathway of spreading that the cancer many have metastasized. This is huge squared because it means you can essentially use targeting one tumor to identify and eliminate distal tumors that you many not even realize exist.

This allows the therapy for treating cancer to, for the first time; end the "wack a mole" problem that has frustrated traditional shot gun methods of treatment involving radiation and chemotherapy ...which by their nature unfortunately damage parts of the body that are not cancer laden but …

Engineers versus Programmers

I have found as more non formally trained people enter the coding space, the quality of code that results varies in an interesting way.

The formalities of learning to code in a structured course at University involve often strong focus on "correctness" and efficiency in the form of big O representations for the algorithms created.

Much less focus tends to be placed on what I'll call practical programming, which is the type of code that engineers (note I didn't use "programmers" on purpose) must learn to write.

Programmers are what Universities create, students that can take a defined development environment and within in write an algorithm for computing some sequence or traversing a tree or encoding and decoding a string. Efficiency and invariant rules are guiding development missions. Execution time for creating the solution is often a week or more depending on the professor and their style of teaching code and giving out problems. This type of coding is devo…

AgilEntity Architecture: Action Oriented Workflow

Permissions, fine grained versus management headache
The usual method for determining which users can perform a given function on a given object in a managed system, employs providing those Users with specific access rights via the use of permissions. Often these permissions are also able to be granted to collections called Groups, to which Users are added. The combination of Permissions and Groups provides the ability to provide as atomic a dissemination of rights across the User space as possible. However, this granularity comes at the price of reduced efficiency for managing the created permissions and more importantly the Groups that collect Users designated to perform sets of actions. Essentially the Groups serve as access control lists in many systems, which for the variable and often changing environment of business applications means a need to constantly update the ACL’s (groups) in order to add or remove individuals based on their ability to perform certain actions. Also, the…
