In 2010 we have again been participating in the Google Summer of Code under the GNU umbrella, with three slots:
Jérémie Koenig, mentored by Samuel Thibault, has been working on adapting the Debian Installer to produce working Debian GNU/Hurd installation images so we can easily offer up to date disc-sets. (Details.)
Emilio Pozuelo Monfort, mentored by Carl Fredrik Hammar (who was a GSoC student in 2007), has been working on a task that may be perceived as less exciting from the outside, but yet is extremely valuable: fixing compatibility problems exposed by projects' testsuites. (Details.)
Karim Allah Ahmed, mentored by Sergio López, has been working on tuning the VM Subsystem in GNU/Hurd to bring the virtual memory management in Hurd/Mach up to date. (Details.)
