Passwordless SSH messes with escaped spaces
Hi, I'm trying to use rsync through ssh to pull files from PCs that need to be backup up. I set up the passwordless authentication and things work fine there. However there's a problem when I try to seal off the SSH access to restrict it to limited rsync only using the "command=" in authorized_keys. That by itself works, however not in combination with spaces in the file names.

strange behavior of R
Hi I observed an interesting behavior of R. Can you find where is the bug, or it is not a bug but made deliberately. - Hide quoted text - > arr = c(); #defined the empty array > a= c("x1", "x2"); > b = c("y1", "y2"); > arr = rbind(arr,a); #row bind the first character array -a > arr =

System Time Jumps During Boot on CentOS 7
Hi All, Just noticed a funny time jump on a testing CentOS 7 VM. Specifically the system time jumps around by a few hours during system boot. The below is a selection from /var/log/messages during boot: Jan 19 12:49:57 arr-data-dev chronyd[716]: Frequency -0.829 +/- 0.007 ppm read from /var/lib/chrony/drift Jan 19 12:49:57 arr-data-dev polkitd[720]: Started polkitd version 0.112 Jan 19

[LLVMdev] Aliasing Question
I just have two questions regarding the following small piece of code: if (var > start*end) { arr[var] = arr[var-1]; } else { arr[var] = arr[var+1]; } 1. Why does llvm put the address computation in the branched blocks instead of the common dominator? 2. Why does the AliasAnalysis return MayAlias instead of MustAlias? Thanks. -------------- next part

Semi-OT: awk
This is odd, and annoying. CentOS 6, current. Here's my awk script: { room = substr($0, 48, 10); arr[$2,room,$1] = $0; } END { for ( i in arr ) { for ( j in arr[i] ) { for ( k in arr[i][j] ) { print arr[i][j][k]; } } } } And when I run it, it complains awk -f awksort proplist7 awk: awksort:7: for ( j in arr[i] ) { awk: awksort:7:

Subsetting the "ROW"s of an object
Hmmm, yes, there must be some special case in the C code to avoid recycling a length-1 logical vector: dims <- c(4, 4, 4, 1e5) arr <- array(rnorm(prod(dims)), dims) dim(arr) #> [1] 4 4 4 100000 i <- c(1, 3) bench::mark( arr[i, TRUE, TRUE, TRUE], arr[i, , , ] )[c("expression", "min", "mean", "max")] #> # A tibble: 2 x 4

Apply approx() to an array and eventually a list of arrays
Hello all, I'm struggling to grasp how I might use lapply() instead of looping to run approx() on a list consisting of multiple arrays - each of equal dimension. But simpler than that, I haven't been able to successfully apply approx() to an array, unless I loop through the third dimension and extract the matrix. See example code below... Any suggestions will be gratefully received. Thanks

problem with interaction in lmer even after creating an "interaction variable"
Dear all, I have a problem with interactions in lmer. I have 2 factors (garden and gebiet) which interact, plus one other variable (home), dataframe arr. When I put: / lmer (biomass ~ home + garden:gebiet + ( 1|Block), data = arr)/ it writes: /Error in lme4::lFormula(formula = biomass ~ home + garden:gebiet + (1 | : rank of X = 28 < ncol(X) = 30/ In the lmer help I found out that if not

bwplot [lattice]: how to get different y-axis scales for each row?
Dear expeRts, How can I get ... (1) different y-axis scales for each row (2) while having the same y-axis scales for different columns? I coulnd't manage to do this with relation="free" [which gives (1) but not (2)]. I also tried relation="sliced", but it did not give the same y-axis scales within each row (see the fourth row). Further, it "separates" the

Compact sums in functions definitions
I'm trying to make more compact the definition of a function as for example: f <- function(x) 2/x+3/x by simply defining the array of coefficients arr = c(2,3) and setting: g <- function(x) sum((arr/x)) Everything seems to work fine because the values returned by f and g result coincident for different values of their argument, but when I try to plot the function g using: x =

Data.matrix fail to convert data.frame into matrix

Missed opportunity in the midend, unsigned comparison
Hi everybody, I see a missed optimization opportunity in LLVM that GCC catches and I'd love to hear community's input. Here's the original C code: 1 char arr[2]; 2 char *get(unsigned ind) { 3 if (ind >= 1) { 4 return 0; 5 } 6 return &(arr[ind]); 7 } The variable `ind` is unsigned so, based on the comparison, if it is not greater or equals to one, than it is
