Macbook Pro Hard Drive Upgrade

Posted on June 30th, 2008 in Computing,Hardware by Ross Wynne

I have just completed a (forced) upgrade to my Macbook Pro with a 320GB Seagate (ST9320320AS). “Forced” simply because I woke up this morning turned on my mac and suddenly heard a load of clicking sounds!
I can confirm that this model of drive is compatible with the Macs and was actually a little quicker than the original hard drive.

It’s quite easy to do but it does involve over 20 screws being undone!

I’ve finally got around to uploading my FYP to my blog, check it out in the pages menu to the left. There’s a PDF and html version for your perusal…

If you don’t understand this hex code then where have you been the last three days?
It is ‘allegedly’ the code that breaks the copy encryption on Blu-Ray and HD-DVD discs.
Why you might ask am I posting it? Well… When this was leaked on the 30th of April it found itself on a few blog sites and people started Digg-ing the story. Then the Advanced Access Content System Licensing Administrator sent a legal threat to Digg’s operators telling them to remove the story from their site. Upon this becoming known the backlash ensued and one of the greatest uprisings in anti-censorship began. Blogs and websites all over the world have posted this innocuous number as I am doing here to stop the insanity of the notion that a number can be ‘owned’ by a corporation.

Free the numbers!!!

UPDATE: It seems people are now going to ridiculous lengths to keep the number free…

Can I have Chilly Chips with that…

Posted on June 21st, 2006 in Computing,Hardware by Ross Wynne

Given my love affair with computing I couldn’t miss the latest news story going around about the new microchip that was recently tested that produced speeds of 500Ghz using a basic Silicon-Germanium compound. It turns out that the chip could only go that fast when only 4 degrees above absolute zero.

The thing that has struck me though is the temperture that they used in getting this chip going is actually not that exotic when used in space. When a spacecraft is shielded from the sun the components inside would reach about 5K (5 degrees above absolute zero).

Hence this type of processor could easily have major applications in space telescopes and space craft. I would conceed however that the energy needed to run this processor is probably prohibitive at the moment.
