Genetic Revert & Refresh

The premise is pretty simple, what if we could press the undo button for DNA related aflictions. It's a sound theory but whether it would actually work or not is questionable.

The possibilities!

This particular train of thought was mostly born from thinking about cancerous cells, which grow out of control due to a minute mutation in the DNA of a cell. The immune system doesn't identify the cancerous cells as something that is dangerous because they're near identical to any other healthy cell. The same could be said with aging, cells slowly mutating & loss of elasticity cause degradation in copying the genetic information to new cells.

CRISPR gene editing theoretically allows us to alter DNA in a live organism. With this technique the ability to alter a DNA sequence needs only the desired information payload to be spliced in. This obviously raises rather large ethical concerns of being able to wildly alter people's DNA and fundamentally change the human genome. Which is much too heavy a philosophical, cultural & even religious discussion for this particular blog! However, simply reverting to a previous non corrupted state of when the DNA was fresh & at its peak? There is no real change there, just a reversing back to a previous version.

In software development we have version control, most famously Git, which allows several versions of complex code & data to be merged together to get the intended end result. The same principle could surely be applied. People could regularly make DNA "commits", allowing the ability to merge, revert & even refresh changes to their own DNA sequence. Think of it like a save point, where the DNA could simply be pointed back to "load" a previous version. This would obviously need to be a regulated & controlled practice by medical professionals otherwise the below would most definitely occur. But if managed properly, the possibilities are quite enticing.

Random Generation That's Not So Random

While I do want the Galliventurer universe to be procedurally & randomly generated, I don't want it to be truly random. There needs to be a modicum of probability involved. Some weighting so that some things are rarer than others. After all we can have too many diamond covered planets or uranium based suns - as you can see I haven't actually started thinking too much about the composition of the planets, stars, etc.

Keeping this probability based random selection in mind, I'm going to be using a dynamically weighted series of arrays to randomly select properties for entities in the Galliventurer universe. Using something very similar to (or based on) this article by Michael Czechowski The main bit of complexity here will be the values of a randomly selected property will affect the weights of the next selection. For example the size of a star will greatly change the weight of the probabilities fo…

Galliventurer - Dreaming of a Universe

n. Galliventurer - one who adventures whilst gallivanting. We have a name. A compound of the words gallivanter & adventurer it fits the game quite nicely. It will also be the name of the player's ship (though, you may be able to have many ships throughout the game).

Also trying something a little different for this project, practicing what I preach as it were. I'm actually going to plan this out a little bit before I ever actually write any code. Oddly I feel that most of my hair brain schemes of previous years have had a fast paced "rush to market before someone else thinks of this" attitude. So obviously there was no time to stop and take a moment to put any thought in before code went into editor. None of those projects ever made it out of the proof of concept phase oddly enough, no prizes for working out why.

In the spirit of all this, things are different this time around. Having given it even two minutes of thought there are several issues.  Prewarming the…

Vacuous Social Data Sharing

It's the not so secret, dirty secret of our modern lives. We live in a golden age of free services that make our lives interconnected on levels that our ancestors couldn't even fathom. Instantaneous realtime interactive updates and vision of someone on the other side of the planet. For free!! We really do live the utopian lifestyle, or do we? 

We are being monetized. The really insidious thing is, we like it. We crave it. Likes, follows, subscribers, retweets, pins, shares, the list goes on. We're subsumed in a culture of instant gratification and constant engagement. These "free services" have hijacked the way we think and live, all while making copious amounts of money from the personal data we all but throw at them. 
Whilst there is an innate understanding in all of us about the nature of how insidious and conniving these services are. We still gobble up every morsel of social media's bright lights and flashy features, mostly without a single thought of who …
