DNA Storage – bringing a future of “teleportation” that little bit closer

Joanne Brink

Joanne Brink

Managing Director - TechWays

Who has heard of DNA storage? You wouldn’t be the only one who hasn’t. DNA storage is going to “soup-up” our current digital storage capabilities to an exponential level – where 3.3 zetabytes of data (pretty much all the data that exists on Earth today plus extra) will fit on a storage device the size of a ping-pong ball

 

DNA Storage, serverless cloud and exponential programming language growth were 3 of the top trends Jason Suttie from Devson and Coding Ground shared at our Future-Skills TechTalk last week Thursday. High school learners, their parents and teachers joined to engage with Jason on the impact of these trends on future skills and marketplace needs. 

 

Organisations like Microsoft are developing DNA storage as we speak. According to Jason, the world of encoding our human genetics and transferring it somewhere else (think “Beam me up Scottie” teleportation) becomes a possibility given these kinds of technologies. “With this kind of storage capacity – every person can have a copy of the entire internet sitting on their harddrive, or multiple copies that show the internet from last year, from last month. The amount of data that will be produced is mindblowing”. 


These Future-Skills TechTalks are hosted the first Thursday of each month – where TechWays founder Joanne Brink talks with experts and industry leaders like Jason about cutting edge technology trends in their industry and how this will play out in future skills needs for our youth.

print ( ) is a built-in function (still to cover what built-in functions are later) that executes data inside the brackets. The results get printed out on the console/results section.

input ( ) is a built-in function (still to cover what built-in functions are later) allows a user to insert info into a program/the code. 

Mad Libs is a phrasal template word game created by Leonard Stern and Roger Price. It consists of one player prompting others for a list of words to substitute for blanks in a story before reading aloud.

  • \t – Horizontal tab – creates a tab space, similar to when you use ‘tab’ on keyboard.
  • \b – backspace – deletes the character before the it.
  • \r – carriage return – same as \n

String Built-in Functions/Methods

Troubleshooting is a form of problem solving, often applied to repair failed products or processes on a machine or a system. It is a logical, systematic search for the source of a problem in order to solve it, and make the product or process operational again.
