Recovering a corrupt Eclipse workspace. April 19, 2009. Today as I sat down at my cubicle and did my daily routine to initiate eclipse. I encountered a horrible sight; eclipse would start and all of a sudden just crash. I first tried the obvious solution, to clean out the workspace. The solution was fairly straight forward. I had to remove org.eclipse.core.resources from my workspace. Cd /Documents/workspace/.metalog/.plugins rm -rf org.eclipse.core.resources. Why I love Solaris’ SMF. 131 comments so far.

PostgreSQL ZFS Snapshot Backups | Letsgetdugg
http://letsgetdugg.com/2010/06/23/postgresql-zfs-snapshot-backups
PostgreSQL ZFS Snapshot Backups. June 23, 2010. I recently had a WD Raptor drive die in a server that hosted our PostgreSQL. Database. I had a ZFS snapshot strategy setup that sent over ZFS snapshots of the live database to a ZFS mirror for backup purposes. Looked good in theory right? With that lesson in mind, I reconfigured our backup system to do it correctly after re-reading the PostgreSQL documentation. Configure your archive directory under. This is how my /rpool/pgdata/db1 Looks like:. PGPASSWORD=...

PostgreSQL memory issues with connection pooling | Letsgetdugg
http://letsgetdugg.com/2012/02/08/postgresql-memory-issues-with-connection-pooling
PostgreSQL memory issues with connection pooling. February 8, 2012. I recently learned a hard lesson with PostgreSQL’s long lived connections; persistent connections expand in memory size without giving any back to the OS. I saw our PostgreSQL database go from 1.2gigs (shared buffers set to 1024m) to 3.8gigs in memory size. Almost 2.6gigs of memory wasted on persistent connections held on by our connection pool. Moral of the story? Configure your connection pool to recycle Postgresql connections.

I have been fairly on and off in the emulation scene. However, I have accumulated enough projects to justify a dedicated emulation section for my work on this site. These are various emulation related pieces of software that I have written or ported. As you would expect from an OSS advocate such as myself, majority of the work here is licensed under the GPL or BSD license. A NES emulator based on FCeu sources with additional mapper support.
