I try to switch my application from Rails 2.2.2 to Rails 2.3.3. In namespace :admin I have a resource-based controller. See controller class Admin::OSystemsController < Admin::BaseController def index ....... end def edit ......... end def update .......... end end Resource is added to routes.rb like map.namespace :admin do |admin| ............ admin.resources :o_systems,

...3/33 Could you pls clarify - do you mean it doesn't yet work with vhost because of a vhost bug, and to test it with the linked patches you had to hack in _F_NEXT? Because I do not see _F_NEXT in indirect descriptors in this patch (which is fine). Or did I miss it? > v2 -> v3: > - Use leXX instead of virtioXX (MST); > - Refactor split ring first (MST); > - Add debug helpers (MST); > - Put split/packed ring specific fields in sub structures (MST); > - Handle normal descriptors and indirect descriptors differently (MST); > - Track the DMA addr/len related info in a separ...

Hello everyone, This patch set implements packed ring support in virtio driver. Some functional tests have been done with Jason's packed ring implementation in vhost: https://lkml.org/lkml/2018/7/3/33 Both of ping and netperf worked as expected. v1 -> v2: - Use READ_ONCE() to read event off_wrap and flags together (Jason); - Add comments related to ccw (Jason); RFC (v6) -> v1: -

Hi, I'm studying math, and i have to make an analysys using Randomised Block Design. I have two factors, i know how to do this in Statistica, but how to do this in R, i read some manuals but the only thing that i have found was 2 factor ANOVA. Please could someone help me, or give some usefull links ?? Krzytsztof Suwada
