| New Skin, New Classes |

Yeah, new skin. Same layout as the old skin but not red, and not fixed-width font. I'm not sure I like this better, but it does have some nice improvements. So, a new semester is upon me. With work and all, I'm taking a lighter courseload -- just 14 hours of classes:
CS 473 is what I'm really looking forward to. I have grand plans to develop a groundbreaking C compiler with super secret technology of my own design, so this class will provide me with the necessary knowledge to do hard-core compiler work (hopefully). I'm already learning how to do parsing properly, and it's been an interesting exercise to thoroughly analyze the skin parsing code for this site, which I wrote in high school when I knew nothing about formal parsing theory, and see what I got right. Surprisingly, I got quite a bit of it right. w00t! EAES 101 is about rocks and stuff. Sleepytime. Actually, we got into global weather patterns today, which was pretty interesting. But mostly this class is about rocks, so I struggle to stay awake. However, it has possibly the easiest lab section ever, and it fulfills my lab sci requirement, so SCORE. ECON 121 is turning out to be a fascinating class. The professor is one of the most enthusiastic teachers I've ever had, which is very good because our textbook and the subject matter in general are quite dry. I'm really getting into this course. Who knows, maybe I'll learn enough to become a brilliant economist and make a killing in the stock market. Yeah right. Very useful knowledge nonetheless. That's about all I've got. Things at work are mostly super-secret right now, so I won't broach that subject, but I'll just say that I'm having a good amount of fun, so Good Times. _WRF |

| Semi-Scientific Filesystem Comparison |
| Tue January 12th, 2010 at 4:34 PM PST |

System: Dual Pentium III (Coppermine) @ 1000 MHz / 133 MHz FSB, 2 GiB ECC SDRAM. Linux 2.6.32-ARCH. Disks: four 10,000 RPM UltraSCSI 320 disks in RAID5 (hardware accelerated). Max read speed: ~50 MB/s. Max write speed: ~35 MB/s Setup: filesystems created on a 10 GiB (10737418240 bytes) zero-filled file, mounted via loop device. Test 1: unpack an uncompressed tar archive of the Chromium browser source code at revision 35890 (2.6 GiB, 222964 files) to the test filesystem. Test 2: delete all files created in test 1. (Note: CPU usage is out of 200%, and the loop device and tar command make up a large part of it) JFS Test 1: 3:25.85, 32% CPU JFS Test 2: 0:22.38, 64% CPU XFS Test 1: 4:22.26, 43% CPU XFS Test 2: 1:16.31, 89% CPU Ext4 Test 1: 3:28.61, 28% CPU Ext4 Test 2: 0:24.12, 72% CPU ReiserFS Test 1: 4:28.20, 39% CPU ReiserFS Test 2: 0:33.93, 91% CPU So, JFS wins this one, which is good, because that's what filesystem I'm already using. :) Test procedure: |
