Hi all, I can''t find any good talk about this subject and would like some insights and advices on the cache side in xen. I discovered that a domO power outage can lead to a severe filesystem corruption of the domUs. The domO is a dual disk dell server with a PERC controler in writethrough cache mode, the disk cache is disabled, the scheduler in the domO/domU is NOOP, the domO is holding

I got Wine onto my computer. Now I have a bunch of .exe files and I can't get much of anything done. I saw a file named Start.exe, double-clicked it and got the following from Archive Manager: End of Central directory signature not found How do I get past this? I need to get Wine going so I can download a whiteboard application I need to tutor for Brainfuse.com.

Hi Rolf, this topic is probably already saturated, but here is a tidyverse solution: ``` library(purrr) x <- list( ? `1` = c(7, 13, 1, 4, 10), ? `2` = c(2, 5,? 14, 8, 11), ? `3` = c(6, 9, 15, 12, 3) ) x |> ? pmap(~ c(..1, ..2, ..3)) |> ? reduce(c) #> [1]? 7? 2? 6 13? 5? 9? 1 14 15? 4? 8 12 10 11? 3 ``` Here, we map over the elements of the list in parallel (hence pmap),

A colleague asked me if there is a way to specify with a ***variable*** (say ``cflag'') whether there is an intercept in a linear model. She had in mind something like lm(y ~ x - cflag) where cflag could be 0 or 1; if it's 0 an intercept should be fitted, if it's 1 then no intercept. This doesn't work ``of course''. The cflag just gets treated as another predictor

Sorry to append, but I just realised that of course ``` x |> ? pmap(c) |> ? reduce(c) |> ? unname() ``` also works and is a general solution in case your list has more than three elements. Here, we map in parallel over all elements of the list, always combining the current set of elements into a vector, and then reduce the resulting list into a vector by combining the elements

For reasons best known only to myself ( :-) ) I wish to create a data frame with 0 rows and 9 columns. The best I've been able to come up with is: junk <- as.data.frame(matrix(0,nrow=0,ncol=9)) Is there a sexier way? cheers, Rolf ###################################################################### Attention:\ This e-mail message is privileged and confid...{{dropped:9}}

I want to do something like: TH <- sprintf("%1.1f",c(0.3,0.5,0.7,0.9,1)) plot(1:10) legend("bottomright",pch=1:5,legend=parse(text=paste("theta ==",TH))) Notice that the final "1" comes out in the legend as just plain "1" and NOT as "1.0" although TH is [1] "0.3" "0.5" "0.7" "0.9"

I have factors with levels ``Unit", "Achieved", and "Scholarship"; I wish to replace these with "U", "A", and "S". So I do fff <- factor(fff,labels=c("U","A","S")) This works as long as all of the levels are actually present in the factor. But if ``Scholarship'' is absent (as if often is) then

I recently noticed that after starting xend ethtool no longer work for my e1000 card. In my 2.X box which is a P4, ethtool is working after xend start. Same version of e1000 on both boxes. The unstable box is a Tyan 2462 SMP, FC4 dom0 The 2.X box is Dell P330 UP, Centos 4.1 domO Until xend start ethtool is fine, in both setups I am using the e1000 as eth0. Regards, Ted

I don''t understand why my program does not get the file that I try to upload. It returns the following error when I try to upload a small file: NoMethodError in LogfileController#create You have a nil object when you didn''t expect it! The error occured while evaluating nil.original_filename #{RAILS_ROOT}/app/models/logfile.rb:9:in `file=''

Hi All. I have a mysql statement that I would really really like to call from my Ruby program which goes like this: SELECT a, b, DAYOFWEEK(date_time) as DOW, HOUR(date_time) at hr, AVG(x/y) FROM records; This is possible by creating a 3-dimentional array of a, b, date_time containing x/y, and then finding averages and putting it into a 4-dimensional array of a, b, dow,

I see a book coming: "666 ways to do the same thing in R ranked by sexiness." Kidding aside, if you look under the covers of some of the functions we are using, we may find we are taking steps back as some of them use others and perhaps more functionality than we need. But for a new reader , looking at many approaches may open up other ways and ideas and see the problem space as quite

I have (toy example): x <- list(`1` = c(7, 13, 1, 4, 10), `2` = c(2, 5, 14, 8, 11), `3` = c(6, 9, 15, 12, 3)) and f <- factor(rep(1:3,5)) I want to create a vector v of length 15 such that the entries of v, corresponding to level l of f are the entries of x[[l]]. I.e. I want v to equal c(7, 2, 6, 13, 5, 9, 1, 14, 15, 4, 8, 12, 10, 11, 3) I can create v

Hi All. I have one newbie question- How do I connect to a remote MySQL server using Ruby on Rails? Is it something simple like changing a few lines in database.yml?? Thanks in advance. Lisa -- Posted via http://www.ruby-forum.com/.

Avi I fear this was all a huge social experiment. Testing if a post titled "sexy way" would increase engagement...

Hi, is there any possibility to get a XEN DomO and DomU running with bridget and routed mode together. The reason behind this is, to get the requests via the official IPs to the DomU''s (routed-mode) and the interworking between the DomU''s with connected with help of the (bridged-mode). I got it work, with setting everything up manually. But as I understood the

I wish to pass a vector ``y'', some of whose entries are NAs to a fortran subroutine which I am dynamically loading and calling by means of .Fortran(). The subroutine runs through the vector entry by entry; obviously I want to have it do one thing if y[i] is present and a different thing if it is missing. The way I am thinking of proceeding is along the xlines of: ymiss <- is.na(y)

Admit it, Rolf. Haven't you wondered if S, in a more private way, is sexier than R? OK, kidding aside, we have talked this to death. Just FYI, the conversation was stimulating for some of us and I have continued on my own and located functions I see as useful in the stringi and stringr packages to make my silly version ever less silly!

Alpine linux is a distribution that uses musl libc instead glibc. Here are my steps to reproduce: On Alpine linux, download LLVM, Clang, LLD 6.0.0 from releases.llvm.org, and build them from source. $ clang -c hello_world.c $ ld.lld --gc-sections -m elf_x86_64 -o hello_world /usr/lib/gcc/x86_64-alpine-linux-musl/6.4.0/../../../../lib/Scrt1.o

If a PCI device has been passed to a domU is it possible to set its latency from the domU or does it have to be done from the domO? When I attempt to set a devices latency from the domU with setpci I do not receive an error message back indicating a problem, however the latency as viewed with lspci -v is not changed. The same setpci command from the dom0 successfully changes the latency and the
