Hi all, I''m trying to include the ''runt'' gem (http://runt.rubyforge.org/) in my Rails project. I''ve tried a few ways of doing this. I''ve tried installing runt using ''gem install runt'' and then trying to do "require ''runt''" in my environment.rb, and I''ve a...

I am planning on using Runt to calculate recurring events. I calculate a Runt object in the view and use it to see if it includes a certain date, which is populates from the database, and display the info for that date if it is included. I have recurring events for every week, which was pretty easy to set up. I can just sa...

TO be able to boot from USB devices. You have the right idea. You need an initial ramdisk to sleep, or you need the kernel to be patched to allow time for the USB device to be initialized.

I''m using the runt library [1] to do some temporal expression matching. I want to keep the expression in a binary field in my db.

I''m working on a project that has event scheduling and I need to get date recurrence going on it. I found the Runt library which looks like it has pretty much everything handled, but I was wondering if there are any tutorials out there for using Runt with Rails, or better yet some helpers or a plugin for it. I tried searching through the mailing list archives, but searching is down on Ruby Forum, and gmane&...

Hi, Jens & Rusty This version is rebased against linux-next which resolves the conflict with Paolo Bonzini's 'virtio-blk: allow toggling host cache between writeback and writethrough' patch. Patch 1/3 and 2/3 applies on linus's master as well. Since Rusty will pick up patch 3/3 so the changes to block core (adding blk_bio_map_sg()) will have a user. Jens, could you please

Hi, all Changes in v7: - Using vbr->flags to trace request type - Dropped unnecessary struct virtio_blk *vblk parameter - Reuse struct virtblk_req in bio done function - Added performance data on normal SATA device and the reason why make it optional Fio test shows bio-based IO path gives the following performance improvement: 1) Ramdisk device With bio-based IO path, sequential

This patchset implements bio-based IO path for virito-blk to improve performance. Fio test shows bio-based IO path gives the following performance improvement: 1) Ramdisk device With bio-based IO path, sequential read/write, random read/write IOPS boost : 28%, 24%, 21%, 16% Latency improvement: 32%, 17%, 21%, 16% 2) Fusion IO device With bio-based IO path, sequential
