Hello, I think the links should be useful for someone who looking for PHP 5.2 RPM using at CentOS. Have fun! http://oss.oracle.com/projects/php/ Overview This project supplies PHP 5.2.9 RPM packages built for Oracle Enterprise Linux 4.7 and 5.3 on x86 and x86_64. They will also install on Red Hat Enterprise Linux. The PHP command line, CGI interface, and an Apache module are

Hi, folks. I have download the DVD image of CentOS 5.2. Comparing with the DVD image of Upstream OS Provider, I got a surprise: The size of the DVD image of Upstream OS Provider is just 2.87 GB(i386), but the size of the DVD image of CentOS 5.2(i386) is so large that is 3.74 GB! I kown that CentOS's developers did very excellent work on how to make the Upstream OS more availability and add

The incorrect result incurs when the file path contains Chinese character. It seems that dirname/basename action on unit of byte instead of char, so the result in the following example is half of what is expected. > g<-"d:\\$BG!2L4^M-CfJ8(B\\$BG!2L4^M-CfJ8(B.txt" > dirname(g) [1] "d:/$BG!2L4^(B" > basename(g) [1] "$BG!2L4^M-(B" -- HUANG Ronggui,

Get the free pages information through virtio and filter out the free pages in the ram bulk stage. This can significantly reduce the total live migration time as well as network traffic.

Dear list, I want to insert a recorde into a SQLite table by dbGetQuery(), but there is a problem when the value contains quotation mark. > dd<-data.frame(txt=c("having both ' and \" in character.","OK")) > library(RSQLite) Loading required package: DBI > con<-dbConnect(dbDriver("SQLite"),":memory:") >

This patch set contains two parts of changes to the virtio-balloon. One is the change for speeding up the inflating & deflating process, the main idea of this optimization is to use bitmap to send the page information to host instead of the PFNs, to reduce the overhead of virtio data transmission, address translation and madvise(). This can help to improve the performance by about 85%.

Dear David, Thanks for your prompt reply! Sure, I can implement a AST visitor to go through the AST to get the information but I just wonder whether there is any other way to let Clang do so. What I am considering is how to let the generated IR looks like below, which some tools realize: define dso_local i32 @_Z1fPii([51 x i32]* %A, i32 %x) local_unnamed_addr #0 !dbg !7 { entry: ...

obviously, follow code is not working <p> <% if !@group.users.find(session[:user].id) %> <%= link_to "Join This Group", :action => "join", :id => @group %> <% end %> </p> "find" always throw an exception. I want to display the link of "find" fails, what is the right way to do this? Thanks. -- Posted via

Take over this work from Liang. This patch series implements two optimizations: 1) transfer pages in chuncks between the guest and host; 1) transfer the guest unused pages to the host so that they can be skipped to migrate in live migration. Please check patch 0003 for more details about optimization 1). For an idle guest with 8GB RAM, optimization 2) can help shorten the total live migration

The current QEMU live migration implementation mark the all the guest's RAM pages as dirtied in the ram bulk stage, all these pages will be processed and that takes quit a lot of CPU cycles. >From guest's point of view, it doesn't care about the content in free pages. We can make use of this fact and skip processing the free pages in the ram bulk stage, it can save a lot CPU cycles
