I came across this post comparing ZFS to Btrfs. The post is undated and that makes it a bit hard to verify the claims against Btrfs. Although I’m partial towards ZFS, I hope Btrfs catches up. Meanwhile, maybe I should check out Btrfs for myself. Update 2013-12-05: Someone named “sasfater” wrote me an email today […]

I updated my FreeBSD 10.0-CURRENT virtual machine today. It reached r255120 and it’s running with vtnet as its virtual network interface under VirtualBox 4.2.16. I noticed the vtnet0 interface gained 10 Gbit/s virtual wire speed. Previously the interface ran with only 1 Gbit/s virtual wire speed. The actual wire speed depends largely on the physical limitations of […]

Here’s a GNU Bison and GNU Flex version of my MMIX assembly language floating point number preprocessor. The code was developed using GNU Bison version 1.875d and GNU Flex version 2.5. This version allows for entering more complex expressions of floating point numbers involving addition, subtraction, multiplication and division. Extending the grammar to cover trigonometric […]

Here’s the code for a C program I conceived during a rather boring night shift while performing national service some years back. The code was later refined using GNU Bison and GNU Flex for parsing the operand field, yielding the possibility of processing whole expressions involving addition, subtraction, multiplication and division. Instead of specifying IEEE […]
