My data set is in the following format:

[PATCH] inspect: get windows drive letters for GPT disks.
This patch updates the guestfs_inspect_get_drive_mappings API call to also return drive letters for GPT paritions. Previously this worked only for MBR partitions. This is achieved by matching the GPT partition GUID with the info stored in the blob from HKLM\SYSTEM\MountedDevices\DosDevices keys. For GPT partions this blob contains a "DMIO:ID:" prefix followed by a 16 byte binary GUID.

Help with plotting a line that is multicoloured based on levels of a factor
Hi All, I'm trying to plot data that is a time series of flows that are associated with a specific level, and I would like each level to represent a colour in a line plot. Here is some data that approximates what I'm using: date=c(1:300) flow=sin(2*pi/53*c(1:300)) levels=c(rep(c("high","med","low"),100)) data=cbind.data.frame(date, flow, levels)

PHI nodes for atomic variables
Thanks for your explanation. Do you mean that LLVM will not maintain the def-use chain for atomic variables? So it is impossible to directly catch the fact that the load of x at the statement 'data1 = x; ' dependents on data4 (because of the statement x=data4 )? If I want to get such information, may be the only solution is to traverse all the predecessors of the statement 'data1 =

PHI nodes for atomic variables
Hi everyone, I want to track the def-use chain for atomic variables. However, it seems that LLVM will not generate PHI nodes for atomic variables. I present the generated LLVM bytecode for the next code snippet as follow. I found that it only generated PHI node (*%8 = phi i32 [ %4, %3 ], [ %6, %5 ]*) for non-atomic variable 'data2' but not for atomic variable x? Why? With PHI node

scaling axes when plotting multiple data sets
1) When adding additional data sets to a plot using "plot" followed by "lines", is there a way to automate the scaling of the axes to allow for all data sets to fit within the plot area? 2) I attempted to solve this by setting xlim=c(min(c(data1,data2,data3)),max(c(data1,data2,data3))) however, there are some NAs and Infs in these data sets, and min(data1) and max(data1) both

Poor performance with shard
Hey everyone! I have deployed gluster on 3 nodes with 4 SSDs each and 10Gb Ethernet connection. The storage is configured with 3 gluster volumes, every volume has 12 bricks (4 bricks on every server, 1 per ssd in the server). With the 'features.shard' off option my writing speed (using the 'dd' command) is approximately 250 Mbs and when the feature is on the writing speed is
