Im having a issue with games that i can play on windows fine..have very low frame rates under wine ..Games like HL2,CS Source ,,run fine on windows..but with same settings in wine its more like a slide show..I have a ATI card and have Debian lenny's fglxr drivers installed..Native linux 3d games run fine.maybe a bit slower than the windows version..but I believe that has to do with Ati drivers

Hi there I have two object on is a vector T and the other is dataframe C. vector T has more no of rows when comapred with a dataframe Ccolumn[,2].I want to find the the missing rows in dataframe C.That is those values that are not matchig in dataframe C[,2] Kindly give me suggestion on how to go about it.

I'm a taking a compiler course and I'm supposed to implement a scheduler for the LLVM compiler and comapre its persformance to the existing one used by LLVM-gcc. I need some help understanding what is really happening in LLVM-gcc. In CodeGen/SelectionDAG/ I can see four different Schedulers, which one is used by LLVM? Can you give a hint on where/how to add a new scheduler and test

Hello, Newbie question and hope you can help . I have two vector V1 and V2, where length(V2) = length of (V1) * 2; length(V1) ~ 16,000. For each member in V1, I need to compare 2 element of V2 for equality i.e. for (I in 1:length (V1)) { if ( v2[i] == v1[i] & v2[i+1]==v1[i] ){ statement_1 statement_2 . } } This for-loop is too slow

Dear R users, Basically, from the following arbitrary data set: a <- data.frame(id=c(c("A1","A2","A3","A4","A5"),c("A3","A2","A3","A4","A5")),loc=c("B1","B2","B3","B4","B5"),clm=c(rep(("General"),6),rep("Life",4))) > a

Dear help news reader, I'm trying to draw a Kaplan-Meier curve and would like to ask the news group for some help Supposing I have study comapring two drugs, "A", and "B" and I recorde the time to get to the clinical endpoint (Time), in my case becommming virus free. I have setup the following frame: Time c Drug 1 5 1 A 2 7 1 B 3 2 1 A 4 10 1

dear group members, I am looking for a function that assess the stability of cluster. The result of hclust function is an hclust object which can be plot as a dendrogram. However to have confidence in the tree topology usualy bootstap is applied. I understand that I can apply bootstarp on the original data and then run hclust(dist() ) as much as I resampled but how to comapre the topologies the I

Dear all, I have two questions concerning model simplification in GlmmPQL, for for random and fixed effects: 1. Fixed effects: I don't know if I can simply specify anova(model) and trust the table that comes up with the p value for each variable in the fixed effects formula. I have read that the only way to test for fixed effects is to do approximate wald tests based on the standard errors

BIOSs that don't support ISOLINUX, and it would be really helpful if you could tell us what the seriousness of the problem is, because we are supposed to be releasing Debian GNU/Linux 3.0 in about 3 weeks, so testing time is short. Do you know how the standard multiboot feature of mkisofs comapres to all of these? It's supposed to fail on some BIOSes, but in a way that means that you still get to boot the first image. Can we do better than that with the MEMDISK/ISOLINUX combo? While I'm asking simple questions, do you happen to know how DVDs compare on the bootability front? Chee...

Dear R-ians, I am looking for the simplification of a formula to improve the calculation speed of my program. Therefore I want to simplify the following formula: H = Si (Sj ( sqrt [ (Ai - Aj)?? + (Bi - Bj)?? ] ) ) where: A, B = two vectors (with numerical data) of length n sqrt = square root Si = summation over i (= 0 to n) Sj = summation over j (= 0 to n) Ai = element of A with index i Aj

Hi there I have two different asterisk systems (both 1.4) whose dtmf tones are not being picked up by a particular conference system users are dialling into. I can call myself with the phones and hear the tones, but I am guessing perhaps they are too short or somehow different. I have looked and looked but can't nail down the reason. I don't believe this is a general issue, rather some

Caveat: this is not a discussion about *hosting* a rails app on windows. Anyway...Macs are everywhere you look when researching rails (demo vids, tutorials, and pictures from rails training classes). I''m interested in what the pros to using a Mac for rails development are (besides textmate). Is it more of a cultural thing, a what would 37 signals do thing, is it a unix thing, or

Hi all: This series is an update version (hope the final version) of multiqueue (VIRTIO_NET_F_MQ) support in virtio-net driver. All previous comments were addressed, the work were based on Krishna Kumar's work to let virtio-net use multiple rx/tx queues to do the packets reception and transmission. Performance test show the aggregate latency were increased greately but may get some regression
