edge case concerning NA in dim() (PR#13729)
...is not idempotent. I started digging into the type system to figure
out what type graffiti is fouling this up.
Soon I discovered that comparisons with NULL produce zero length vectors, which
I hadn't known was possible, and I started to wonder about the properties of
zero length objects.
L0 <- logical (0)
dim(L0) <- c(0) # OK
dim(L0) <- c(1) # error
dim(L0) <- c(0,1) # OK

Variable as color in a barplot
Dear wise ones,
I have a problem assigning different colors to bars in a barplot.
The data I'm using is the following dataframe (truncated) :

ZDB returning strange values
Hello all, I have a question about what output "ZDB -dddddd" should
produce in L0 DVA fields. I expected there to be one or more
same-sized references to data blocks stored in top-level vdevs
(one vdev #0 in my 6-disk raidz2 pool), as confirmed by the source:
http://src.illumos.org/source/xref/illumos-gate/usr/src/cmd/zdb/zdb.c#sprintf_blkptr_compact

Nested KVM: L0 guest produces kernel BUG on wakeup from managed save (while a nested VM is running)
Hi everyone,
I hope this is the correct list to discuss this issue; please feel
free to redirect me otherwise.
I have a nested virtualization setup that looks as follows:
- Host: Ubuntu 16.04, kernel 4.4.0 (an OpenStack Nova compute node)
- L0 guest: openSUSE Leap 42.3, kernel 4.4.104-39-default
- Nested guest: SLES 12, kernel 3.12.28-4-default
The nested guest is configured with "<type arch='x86_64'
machine='pc-i440fx-1.4'>hvm</type>".
This is working just beautifully, except when the L0 guest wak...
