I''ve done the apple tutorial, Agile ROR (the depot app, I stopped after that, a little to advanced with no base knowledge of Ruby), Why''s guide and my copy of Chris Pine''s book today. After Pine, I''m going to buy either the Wrox book or Ruby for Rails book. I did a search and there''s not too much on the Wrox book (Holzner)

I have a few questions for R: 1. Other than using a built-in function such as mean(), how do I know if it is installed in my current version of R? 2. To get help in R, I can use several ways: ?sort help.search("sort") help(sort) apropos("sort") the help menu are there any other ways to get help? 3. When I see a help menu for a function, does it mean the function is

Hello all. #1 I am working on a rails3 gem called Yarder (https://github.com/rurounijones/yarder). The goal of this gem is to replace the rails logging system with one that is JSON based rather than string based. #2 To this end I also recently asked this list about making the LogSubscribers subscriptions to ActiveRecord::Notifications configurable and am looking at submitting a patch

The memory relating guest domain should be allocated from NUMA node on which the guest runs. Because the latency of the same NUMA node is faster than that of a different one. This patch fixes memory allocation for Address Translation Structure of VT-d. VT-d uses two types of Structures for DMA address translation. The one is Device Assignment Structure. The other is Address Translation

I have an e-commerce site and users check out with a form. The results of that form are sent to a "confirm your order" page via POST. I take great pains to NEVER store the full credit card number on my server--just the last 4 digits. I was very surprised to find that by default Rails will record POST requests with parameters in the production.log. And those parameters

Hi, Keir, These patches are rebased version of Yunhong''s original patches, which were sent out before XEN 3.2 was released. These patches enable MSI support and limited MSI-X support in XEN. Here is the original description of the patches from Yunhong''s mail. The basic idea including: 1) Keep vector global resource owned by xen, while split pirq into per-domain

Hey everybody, I wanted to use the :layout option when calling render @variable (where @variable is some ActiveRecord class instance with a corresponding variables/_variable.html.erb partial view), but as far as I know, Rails doesn''t support this. Here''s a quick patch that allows to use the :layout function: In partial_renderer.rb, add the following elsif block: if

How do you know when a Linux system has been compromised?? Every day I watch our systems with all the typical tools, ps, top, who, I watch firewall / IPS logs, I have logwatch setup and mailing daily summaries to me and I dive deeper into logs if something looks suspicious. What am I missing or not looking at that you security gurus are looking at? I subscribe to the centos and SANS

Fixes made in version 2: 1) Use PML4[257] for ioremap of PCI mmcfg. As full 16-bit segment support would require 44-bits. Since each slot only has 39-bits, we support 2048 PCI segments for now. This can be easily expanded if deemed necessary in the future. 2) Integrated PCI mmcfg access with existing PCI config interface for x86_64. Use MMCFG interface if offset is greater than 256.

Hi, I''ve added some preliminary support for VT-d for paravirtualized guests. This must be enabled using an ''iommu_pv'' boot parameter (disabled by default). I''ve added some python bindigs to allow xend to assign PCI devices to IOMMU for PV guests. For HVM guests this is handled in ioemu. Not sure if it makes sense to handle both cases in one place. The

I''ve installed bootstrap-sass, and added an @import line in my css. Rails won''t find or serve up the bootstrap files. One error msg on the Mozilla console says: The stylesheet http://localhost:3000/assets/bootstrap was not loaded because its MIME type, "application/javascript", is not "text/css". Hmm. If I change the @import to say

I have a form with a text area. I want to have an observer watch the text area and update a div with the running count of characters in the text area. I tried "onchange" but that doesn''t update until you leave the text area. I was able to get it working using AJAX, but it''s silly to make a needless round trip to the server, when the page already knows

Hi, Keir, This patch will move reading and writing of PCI configuration spaces from dom0 to Xen. It also changes VTD code, so that they can touch the PCI configuration spaces with proper lock. This will also benefit MSI support in Xen. Can you give some comments? Thanks! <<pci_conf_xen.patch>> Best Regards Haitao Shan _______________________________________________ Xen-devel
