Spaghetti DNA

Sunday, January 30th, 2011

This is in the category “parallels between life and computers”.

DNA is said to contain the instructions to build an organism, just like software contains instructions for a computer. Poorly structured software is sometimes called “Spaghetti Code” because it’s such an intangible mess. What about the structure of DNA? Here is a nice quote from the linux kernel mailing list (link):

> Human communication methods are all buggy as hell :)

Not to mention that they are slow, inefficient and ambiguous.

But wht did you expect? The original authors of the code are long gone and
maintenance is done by newcomers who are patching the code bit by bit. What
you get from such a development model is pretty predictable: ~1 billion years
old spaghetti DNA that no-one truly understands.

Evolution may be a “poor development model”, but at least DNA has seen billions of years of debugging 🙂

A Harddrive made of solid rock

Sunday, May 17th, 2009

After the relay switch and the cathode ray tube, rotating magnetic storage is the final part that is to be be replaced by silicon. And thus humanity frees the machine from its shaky, creaky, cranky mechanical shackles, and has created the ultimate device: a computer made of solid rock.

A few weeks ago I bought an Intel X25-M Solid State drive for my laptop, and I’m pretty happy with it. Combined with the boot improvements in Jaunty I can go from pushing the power button to seeing my home page in Firefox in just 45 seconds, and that’s including the three seconds it takes to type my password. Plus, the battery lasts significantly longer. Installation is as easy as any regular laptop drive. People say, and I would agree, that this is currently the most effective upgrade you can give to your laptop or desktop.

But don’t take my word for it. Check out this lengthy review, as well as these endorsements by Joel and Linus.

And for those who say boot time doesn’t matter: You’re an energy hog, please turn off your computer at night, and also drive your hummer into a wall.
