Samba and Preallocated Files
A question about capturing videos to a Samba share...
When Apple's Final Cut Pro captures video files, it pre-allocates file space
on the destination volume.
If you capture to a local volume that's physically attached to a Macintosh,
or if you capture to a network volume via AFP (Apple File Sharing Protocol),
you can see that Final Cut instantly creates a file of the antic...

capturing warnings using capture.output
>From the Details section of ?capture.output:
Messages sent to stderr() (including those from message, warning and stop)
are captured by type = "message". Note that this can be "unsafe" and should
only be used with care.
Capturing messages works as expected:
capture.output(message("!!!"), type = "m...

capture.output() duplicates last line unless newline (R-devel bug)
In R-devel (2015-08-12 r69024), capture.output() incorrectly
duplicates the last line unless it ends with a newline. I don't see
this in R 3.2.2 RC (2015-08-13 r69049). It seems to have started
fairily recently; I spotted this yesterday after starting to get
errors in my R.utils check that use capture.output(), cf.

type="message" possibility for capture.output() ?
As far as I can tell, there's no built-in way to get
capture.output() to capture messages (stderr) instead of
stdout ... suggested, fairly trivial, patch below.
f <- function() {
message("abc")
cat("def\n")
}
x <- capture.output(f())
## prints 'abc'
x ## value: "def"

[GSoC 2016] Capture Tracking Improvements - BackgroundInformation
Hey Scott,
There has been quite a lot of research on capture tracking (aka escape
analysis) for Java and other dynamic languages.
See e.g.:

[GSoC 2016] Capture Tracking - False Positives
Hello Anna,
I've been looking into compiling a list of all of the false positives
in the current Capture Tracking Analysis, but I'm having a bit of
trouble getting my head around it all. I feel like I understand it at a
theoretical level but jumping into the implementation is quite
daunting.
I would appreciate any advice you could give to point me in the right
direction.
Many thanks,
Scott

capture.output(), truncated last output without \n (PR#10534)
Full_Name: Philippe Grosjean
Version: 2.6.1
OS: MacOS X; Windows XP
Submission from: (NULL) (81.243.237.235)
Last output from capture.output() is truncated if it does not end with a
carriage return:

[1] "text"
> capture.output(cat("text")) # Missing output!
character(0)

(PR#10534 capture.output(), truncated last output without
This only happens if 'file' is a text connection, and is the expected
behaviour in that case: you cannot capture an incomplete line to a text
connection.
There seems no reason to break the documented behaviour in other cases to
change something that you consider to a bug when file=NULL and the user
does not produce complete output. It would be possible to make use of
isIncomplete() to add a final newlin...

How to capture console output in a numeric format
Hi,
I would like to know how to capture the console output from running an algorithm for further analysis. I can capture this using capture.output() but that yields a character vector. I would like to extract the actual numeric values. Here is an example of what I am trying to do.

Anyone knows how microsoft AEC can deal with mismatches between clocks of capture and render streams?
Hi all,
We all know that mismatch between clocks of ADCs of far-end voice and near-end voice is not allowed in a time-domain or frequency-domain LMS based AEC system. It means that capture and render audio streams must be synchronized to a same sample rate. However, I found that this restriction is removed in microsoft AEC from Windows XP SP1. Anyone knows how microsoft AEC do it? This technology is much helpful for us to implement AEC in common PC. We know that most low-cost soundca...

Capturing warnings with capture.output
Is there any way to include warnings in the output from capture.output? eg:
a <- capture.output(warning("test"))
all.equal(a, "Warning message: \n test ")
Conceptually, this seems like redirecting stderr to stdout, or somehow
changing warning to simple print it's output. I've had a look at
tryCatch and using a warning handler,...

Named capture in regexp
Dear R core developers,
One feature from Python that I have been wanting in R is the ability
to capture groups in regular expressions using names. Consider the
following example in R.

> name.rex <- "(?<first>[A-Z][a-z]+) (?<last>[A-Z][a-z]+)"

OT: Want to capture all SIP messages
I want to capture all SIP messages.
I have about 30 hosts in about 6 colos.
My first thought was dumpcap, but the output file name format bugs me.
What do you use for long term SIP capture?

capture.output(eval(..., envir)) not evaluate in the expected(?) environment
I've noticed the following oddity where capture.output() prevents
eval() from evaluating an expression in the specified environment.
I'm not sure if it is an undocumented feature or a bug. It caused me
many hours of troubleshooting. By posting it here, it might save
someone else from doing the same exercise.

[LLVMdev] RFC: Converting byref captures into bycopy
Hi all,
I have been looking at how to convert by-reference captures into by-copy captures for captured statements and possibly C++ lambdas, and am looking for some feedback on my approach. The motivation for trying to use copy captures is to avoid unnecessary loads that are otherwise required inside the outlined function. This can be important when the outlined...
