Constantine Murenin offered a history of the OpenBSD hardware sensors framework during his talk at BSDCan 2008, describing how it was originally based on a port from NetBSD, then evolved and was eventually ported to all the BSDs. He also discussed his own involvement with the framework, having ported it from OpenBSD to FreeBSD as a Summer of Code project, and how his port was merged into DragonFly BSD. At the end of the talk, there were some interesting ecxhanges between Constantine and Poul-Henning Kamp, the latter explaining why he'd had the code backed out of FreeBSD and why he continues to oppose it being merged back in.

Leslie Hawthorn, a Program Manager in Google's Open Source team, gave a talk at BSDCAN 2008 on Google's ongoing Summer of Code project. She started by explaining what the open source team does, including enforcing license compliance, hosting over 700,000 open source projects with Google Code, academic research, funding open source development, and community outreach including the sponsorship of conferences such as BSDCan. She went on to discuss how she got started running the project after its initial launch in 2005.

Having sponsored four summer of code's now, Leslie noted that Google has had over 1,500 "graduates" and over 2,000 mentors involved, coming from over 98 countries and working with over 175 open source projects. By the end of the currently in progress 2008 Summer of Code, the project will have provided over 10 million US dollars in funding, generating over 6 million lines of code.

"Google Summer of Code 2008 is on! Over the past three years, the program has brought together over 1500 students and 2000 mentors from 90 countries worldwide, all for the love of code. We look forward to welcoming more new contributors and projects this year," begins a page listing all the projects planning to participate in this year's GSoC. Among the numerous planned participtants there are many kernel projects, including DragonFly BSD, FreeBSD, Git, GNU/Hurd, Linux, Minix, and NetBSD.

Student applications for GSoC projects begin today, running through the end of the month. Read on for many of the participation announcements from the above projects. For more information about the GSoC, the program's FAQ explains:

"Google Summer of Code (GSoC) is a program that offers student developers stipends to write code for various open source projects. Google will be working with a several open source, free software, and technology-related groups to identify and fund several projects over a three month period. Historically, the program has brought together over 1,500 students with over 130 open source projects to create millions of lines of code. The program, which kicked off in 2005, is now in its fourth year."

Mark Weinem offered a summary of NetBSD's six 2007 Summer of Code development projects. The projects included: the Automated Testing Framework, "the goal of the ATF project was to develop a testing framework to easily define test cases and run them in a completely automated way"; porting ZFS, "the primary goal of this project was to port volume emulation (ZVOL) functionality in order to mount ZFS file systems"; QoS framework for NetBSD's virtual memory system, "for delay sensitive systems such as streaming multimedia servers and back-end database systems, servicing the reader processes in a timely fashion is more important than the servicing the writers"; kernel file systems in userspace, as a result of the project, "almost all NetBSD kernel file systems can be compiled, mounted and run in userspace"; and hardware monitoring, "the aim of this project was to develop a kernel event notification framework to notify userland of hardware changes e.g. a new USB device being added". Mark added:

"NetBSD has been involved in the Google Summer of Code since its conception in 2005. This year we were glad to once again have the oppertunity to introduce six students to our operating system, to Open Source software development and get them sponsored by Google to work on projects defined by the NetBSD developers."

"Congratulations to the successful students and their FreeBSD Project mentors for participating in another productive Google Summer of Code," Murray Stokely noted on the -announce FreeBSD mailing list. He offered an interesting summary of all of this year's student projects, adding:

"This program encourages students to contribute to an open source project over the summer break with generous funding from Google. We have had a total of over 50 successful students working on FreeBSD as part of this program in 2005, 2006, and 2007. These student projects included security research, improved installation tools, filesystems work, new utilities, and more. Many of the students have continued working on their FreeBSD projects even after the official close of the program. We have gained many new FreeBSD committers from previous summer of code projects already, and more are in the process."
