TWN Scribe Strives to Become Developer Part 3

My journey to become a developer took a break from coding and moved towards understanding Git. As mentioned previously, Tahoe-LAFS moved to Git. In an effort to under pull requests and branches, I decided to test my readings from Pro Git on some documentation tickets, #1407 and #1660. Brian will have to let you know how I did. Once I understand Git, I will work to tackle writing the unit test for #1333.

Tahoe-LAFS on Fedora 14 and pfSense (FreeBSD)

Great progress has been made on the mailing to package Tahoe-LAFS for Fedora 14 and pfSense (FreeBSD). The Fedora test machine is an One Laptop Per Child (OLPC). The Fedora build experiences issues in that it attempts to build the pycryptopp egg from the source tarball. This is a result of Tahoe-LAFS only having a 64 bit buildbot for Fedora. Tahoe-LAFS would love someone to contribute a buildbot running 32 bit Fedora. On the suggestion of the pfSense forum, Vladimir Arseniev built Tahoe-LAFS on FreeBSD 8.1. If Tahoe-LAFS could be packaged for FreeBSD, this would ease the process of installing/packaging it for pfSense.

Looking for the Ultimate Distributed Filesystem

Roland Mas blogged about his quest for "the ultimate distributed filesystem. In it, he compared Tahoe-LAFS, Ceph and XTreemFS. Zooko provided some clarifications in regards to Tahoe-LAFS to Roland.
