I bet the low 29 bits are zeroed. That is the difference between the 52 bit double

Warning messages when using rbind
Hello,
I have been using a very simple rbind approach (simple enough for me to
understand) to combine data files within R.
It seems to work fine, but then generates warning messages for reasons that
I can't begin to understand. The text below shows the issue.

arrows()/log scale/clipping (?) (PR#1039)
arrows() seems to hang when either x or y scale of the plot
is logarithmic and the arrows requested go beyond the plot
(by more than a certain amount). I didn't go into C code to
find it, but here's a function that exercises the bug a bit ...
arrow.bug2 <- function(y0=1,y1=10,log="y") {
plot(c(0.1,1),c(1,10),log=log)
arrows(x0=0.5,
y0=y0,
x1=0.5,

Sweave bug? when writing figures / deleting variable in chunk
I have found a quite strange (to me) behaviour in Sweave. It only
occurs in the following situation:
1. define a variable in one chunk
2. use it within a subsequent figure-generating chunk
3. delete it at the end of that same chunk
Then the Sweave driver chokes, not finding the variable name when
generating the figure
Example:
% document bug2.Rnw
\documentclass{article}
\usepackage{Sweave}

[PATCH 0/2] ocfs2: two bug fixes about xattr and inline-data
Mark and Joel,
I found two serious bugs about xattr and inline-data.
the first bug:
in ocfs2_mknod(), we check and found the ACL or security xattr entry
could be set into inode in ocfs2_calc_xattr_init(), then don't reserve
block for them. But in ocfs2_mknod_locked(), if we found ocfs2 support
inline-data, then set id_count with the max_inline_data. After that, we
set acl/security xattr

[LLVMdev] Is this a bug in clang?
This code is undefined, meaning that all bets are off, don't do it.
I.e. It reads the value of I between two sequence points and uses it
for something other than determining the value written. From: Csaba

[LLVMdev] Is this a bug in clang?
Hello,
Is this a bug in clang, or a bug in my thinking?
/Joe Armstrong
/*
When I compile the following program I get different answers in clang and gcc.
$ gcc bug2.c
$ ./a.out
j = 40
$ clang bug2.c
$ ./a.out
j = 41
I think the correct answer is 41. If my understanding of C is correct
(which, or course, it might not be) the incremented value of i++ is
first made available

So... Are 40 and 41 the only legal behaviors or are there more?

Read the data from a text file and reshape the data
I have a data set for different time intervals. The data has three comment
lines before data for each time interval. For each time interval there are
500 data points. I want to change the dataset such that I have the following
format:

[PATCH V3 0/2] [BUGFIX] virtio/console: Fix two bugs of splice_write
Hi,
This patch set fixes two bugs of splice_write in the virtio-console driver.
[BUG1] Although pipe->nrbufs is empty, the driver tries to do splice_write.
=> This induces oops in sg_init_table().
[BUG2] No lock for competition of splice_write.
=> This induces oops in splice_from_pipe_feed() by bug of any user
application.

Upgrade 4.8 to 4.9 with Backend-Change to lmdb?
Hi list,
are there preparations for upgrading a samba 4.8.5 to 4.9.1 via
van-belle-repository to change the backend db? Is there some handwork

[LLVMdev] Tablegen binary literals
Hi all
Currently tablegen parses binary literals such as 0b011 and immediately turns them in to integers internally. Due to this, 0b011 is a 2-bit value because tablegen will happily drop leading zeroes on integers.
I propose that we change this, and store binary literals with a size. I think this is much more natural, as when the user writes a value with 3 bits, I think they expect to get a
