Amiga reborn...

So the main disk failed in my Amiga. By failed I mean completely stopped spinning, does not even get warm when I plug it in. While I work to save any data I can, hopefully more on this later, I decided to "start from scratch". The value in starting over is I can take a fresh look at Amiga OS and what it's like to use the various websites for software. I was able to install the OS and all the updates in a matter of minutes with little hassle. Thinking back to the early days of OS 4 it's really progressed well.

Viva la Amiga!

With Amiwest 2011 coming around the corner I thought I would do a little more to share about my favorite computer, the Amiga. Born 1985, the Amiga 1000 was an amazing achievement for a small band of software and hardware hackers. It featured color screens and 16 bit sound back when MAC's where grey scale and PC's green screens. In addition to having great looks the Amiga also had a classy personality with full multitasking and DMA between a custom chipset. DMA means Direct Memory Access and that one of the BIG secrets of how it worked.

Learning all about Linux schedulers...

I've recently been looking in to the process scheduler linux uses. I found a good write up here: which includes a list by kernel version. The process scheduler is different from the IO scheduler and much harder the change.

Here is the linux scheduler history from the wikipedia:

Linux pre-2.6 Multilevel feedback queue
Linux 2.6-2.6.23 O(1) scheduler
Linux post-2.6.23 Completely Fair Scheduler
