[PATCH libnbd discussion only 0/5] api: Implement concurrent writer.
This works, but there's no time saving and I'm still investigating
whether it does what I think it does. Nevertheless I thought I would
post it because it (probably) implements the idea I had last night
outlined in:
https://www.redhat.com/archives/libguestfs/2019-June/msg00010.html
The meat of the change is patch 4. Patch 5 is an example which I
would probably fold into patch 4 for

subsetting a data.frame
Dear all,
I would like to be able to subset a data.frame in a special way. I will put here an example:
Score Name
88 000019_0070
88 000019_0070
87 000019_0070
79 002127_0658
79 002127_0658
77 002127_0658
So, for the above example I would like to have a new data.frame that has only the best "Score" for each

v1:
https://www.redhat.com/archives/libguestfs/2019-June/msg00014.html
I pushed a few bits which are uncontroversial. The main
changes since v1 are:
An extra patch removes the want_to_send / check for nbd_aio_is_ready
in examples/threaded-reads-and-writes.c. This logic was wrong since
commit 6af72b87 as was pointed out by Eric in his review. Comments

qplot: plotting precipitation data
Dear list,
I wish to plot chromatin precipitation data: I would like to have a
rectangles (x:end-start, y:peak) but I do not have an idea how to define x

mydata is a subset of a larger file.

Simple Question?
Greetings,
I am new to R, but trying to put in the time to learn. I have read the R
manual and several other introductory texts; however, there is nothing like
actually putting it into practice. So here is my problem, and its more of a
learning exercise for myself than anything else, but I'm stuck and getting
extremely frustrated that I can't figure it out.
I'm trying to make a

another buffer overrun in sperl5.003
Summary:
Any user can gain root privileges on a Intel Linux system with suidperl
5.003 (having the suid bit, of course) even if "SUIDBUF" and "two suidperl
security patches" have been applied. Non-Intel / non-Linux platforms may
be affected as well.
Quick fix:
chmod u-s /usr/bin/sperl5.003 (what else?)
Details:
There is a nasty bug in mess() (util.c): it is possible to

Whole genome searching of 100bp "D" sequence
Hi,
I was wondering I'm going about this in the correct way. I need to test if
there are coding sequences or exons in hg19 which match a string of 100bp
"D" i.e. [A,G or T]. However I'm getting a strange result.
I get a hit on chr7, using the 100bp search however when I search with 60bp
sequence of "D" I don't get any hits.

[PATCH -v2 0/3] jbd2 scalability patches
This version fixes three bugs in the 2nd patch of this series that
caused kernel BUG when the system was under race. We weren't accounting
with t_oustanding_credits correctly, and there were race conditions
caused by the fact the I had overlooked the fact that
__jbd2_log_wait_for_space() and jbd2_get_transaction() requires
j_state_lock to be write locked.
