“Requirements Explosion”

In Response to InVivoVeritas, another commenter writes: Thanks for an interesting post. As you’re probably aware, there is a well-known phenomenon in software development called the “requirements explosion”. It’s documented, for example, in Robert Glass’s book, Facts and Fallacies of Software Engineering. Even after a specification is complete, and especially as concrete implementation of the specification gets underway (i.e. development of the actual software begins), a plethora of other requirements come out of the woodwork. Several things might account for this, including (1) the requirements were probably incomplete to begin with; (2) not all the implications of the requirements were thought through in advance; (3) the stakeholders don’t like what the “incarnation” of their specifications in functional software actually looks Read More ›

Software Engineer’s Off the Cuff Requirements List for Simple Cell

InVivoVeritas writes: Here is the quote from the Jack W. Szostak interview: We think that a primitive cell has to have two parts. First, it has to have a cell membrane that can be a boundary between itself and the rest of the earth. And then there has to be some genetic material, which has to perform some function that’s useful for the cell and get replicated to be inherited. The part we’ve come to understand reasonably well is the membrane part. The genetic material is the harder problem; the chemistry is just more complicated. The puzzle has been understanding how a molecule like RNA can get replicated before there were enzymes and all this fancy biological stuff, protein machinery, Read More ›

New Research Continues to Point to a Super Progenitor

Everyone knows biology is full of complicated designs, but evolutionists think it arose spontaneously, as a result of the play of natural laws. In other words, it happened to happen. First there was nothing, then there was something, then that something became very complicated. All this just happened to happen.  Read more

The Book is not the Ink and Hardware is not the Software

  In this post the UD news desk quotes OOL researcher Jack Szostak:  “We think that a primitive cell has to have two parts. First, it has to have a cell membrane that can be a boundary between itself and the rest of the earth. And then there has to be some genetic material, which has to perform some function that’s useful for the cell and get replicated to be inherited.”   He believes they have the “membrane” part figured out, which leads him to suggest that they are about “halfway” to figuring it all out. Really?  Consider a computer in a paper sack.  If I figure out how to make a paper sack does that mean I am “halfway” toward Read More ›
