Bacterial DVD Holds 50TB 268

Posted by ScuttleMonkey from the your-cdrom-wants-penicillin dept.
CAMags writes to tell us that a Harvard Professor is claiming to have developed a new variant of a protein called bacteriorhodopsin (bR) that, when layered on a DVD, can store up to 50TB of data. From the article: "The light-activated protein is found in the membrane of a salt marsh microbe Halobacterium salinarum and is also known as bacteriorhodopsin (bR). It captures and stores sunlight to convert it to chemical energy. When light shines on bR, it is converted to a series of intermediate molecules each with a unique shape and color before returning to its 'ground state.'"

      That's not a very good answer - it reveals a bunch of negatives that are likely deal-breakers:

      1) You're a perfectionist, which means you may find it difficult to handle mistakes made by co-workers.
      2) You're a perfectionist, which means you may find it difficult working on a team with people who are not perfectionists.
      3) You're an admitted perfectionist, which makes it likely that you will attempt to cover up any mistakes you do make, rather than admit them.
      4) You're a perfectionist and you take extra time to try to accomplish a task, rather than doing it as well as it needs to be done and having it in on time. Most employers don't expect or actually want perfection - they know it isn't attainable.
      5) You're full of shit and just told the interviewer what you thought they'd want to hear, meaning that you're much less likely to be candid in other areas as well.

      The best answer, of course, would have been "FUCK YOU YOU CUNT I have Tourette's Syndrome ASSLICKER!" It would allow you to scream anything you like with impunity, and they'd be worried about getting sued if they didn't hire you.
