[RFC][PATCH 1/2] Btrfs: try to allocate new chunks with degenerated profile
If there is no free space, the free space allocator will try to get space from the block group with the degenerated profile. For example, if there is no free space in the RAID1 block groups, the allocator will try to allocate space from the DUP block groups. And besides that, the space reservation has the similar behaviour: if there is no enough space in the space cache to reserve, it will reserve the space acc...

return status and non-regular files?
Recently, I ran rsync and got the following message: skipping non-regular file "981005_plteph-de405s.bsp" It turns out that the file in question is really a degenerate link that points back to itself. lrwxr-xr-x 1 18450 other 24 May 9 20:38 981005_plteph-de405s.bsp -> 981005_PLTEPH-DE405S.bsp The confusing this is that although rsync printed what looks like an error, it still returned a status of zero (i.e. success). My question is: what s...

Trouble using Ecdf () from the Hmisc library
...producible example: > library (Hmisc) > x <- read.csv ( file = 'http://www.stat.osu.edu/~pkapat/miscl/Data4Ecdf.csv') > table (x[, c('X1','X2')]) X2 X1 A B 6 0 1 13 7 20 15 13 26 16 13 13 17 10 19 18 12 10 As you can see (X1=6,X2=A) is a degenerate cell and (X1=6,X2=B) is "near" degenerate! So, errors/warnings are certainly expected while dealing with these, as seen here: > Ecdf (~Y|X2, groups=X1, data=x) > Ecdf (~Y|X2, groups=X1, data=x, label.curves=FALSE) Hence the question: Is there a robust function which can ignore suc...

Degeneration of CPU Performance
Hello everybody! We have a interesting issue about dovecot behavior here. First, the scenario: We have 2 server running with the same load, one with our old pop3 solution (out of date) and other with Dovecot. We realized that dovecot are comsuming more CPU, and this consumption is growing day by day. When we starts dovecot, it runs between 40%-45% of CPU consumption and our old

findInterval(all.inside=TRUE) for degenerate 'vec' arguments
What should findInterval(x,vec,all.inside=TRUE) return when length(vec)<=1, so there are no inside intervals? R-3.3.0 gives a decreasing map of x->output when length(vec)==1 and -1's when length(vec)==0. Would '0' in all those cases be better? > findInterval(x=c(10, 11, 12), vec=11, all.inside=TRUE, rightmost.closed=FALSE, left.open=FALSE) [1] 1 0 0 >

nrow(rbind(character(), character())) returns 2 (as documented but very unintuitive, IMHO)

I would consider m==0 a degenerate case, where there is no data, but I personally find matrices (or data.frames) with rows but no columns a very strange concept. The converse is not true, I understand the utility of columns but no rows, particularly in the data.frame case, but rows with no columns are observations we didn't obse...

Subsetting a data.frame degenerates at one column?
Greetings. At the moment, I'm applying R to some AIX 'nmon' output, trying to get a handle on some disk performance metrics. In case anyone's interested: http://docs.osg.ufl.edu/tsm/pdf/ some of them are more edifying than others. (ahem) I'm trying to develop a somewhat general framework for plotting these measures, in the hopes that it's of some use to people other

RWeka - Error when attempting to summary() model
...an expected (10 vs 1586?), and the summary() command fails with the error I mentioned I haven't seen anyone run into. My guess is something is wrong with the specification of the training set, but when I add control=Weka_control(F=1) to specify only one fold, the end result is the same with the degenerate confusion matrix error. Is there some other way I should be forcing it to train on more rows? Is that issue related to not being able to generate a confusion matrix? > attach(q) > nrow(q) [1] 1586 > summary(Site) A B C D E F 265 190 260...

new ogg-tools module in cvs
FWIW, I've just imported my mng-over-ogg code into xiph.org cvs. There are currently too tools, both under the new 'ogg-tools' module: 'oggmerge' is intended to multiplex files of various formats into a single ogg bitstream. Currently it only creates degenerate mng-over-ogg files. Next step is to add support for multiplexing with ogg vorbis files, and jack will likely be using it for his midi work. 'oggplay' is intended to be a general testbed player for these new multiplexed substream formats. Currently it doesn't work at all, but I'...

[LLVMdev] Language lawyer question
...n implementation-specific "must copy" or "must not copy" behavior, you could tweak the test case as needed, I suppose. But under aggressive optimization, you rapidly approach "must copy" semantics, and then the question is why you don't do that for even the degenerate cases. So again, it turns into an optimization test case. Shantonu -------------- next part -------------- An HTML attachment was scrubbed...

Looking to maximize a conditional likelihood
...ion that is basically logistic conditional on the number of successes within strata. What would be a good starting place for this? A complication is that the denominator includes a term that is the sum over all permutations. Although there is no time dimension to the problem, it's possible a degenerate use of the Cox proportional hazards model (in the survival package of 1.7) will do what I want. Here's a little more detail on the function, though this is still quite terse. Pseudo Tex notation: We have cases in clusters. y_ij is the outcome (0 or 1) for the j'th case in the i'th c...
