I'm trying to understand the R internals a bit better and reading over the documentation. I see that there is a bit related to whether an object is S4 (S4_OBJECT_MASK), and also the object type S4SXP (25). The documentation makes clear that these two things aren't the same. But in practice, will the S4-bit and object type ever disagree for S4 objects? I know that one can set the bit

Hi; Before I tell a customer that this would require custom development I figured I would ask here. Does Asterisk support pager notification of new voicemails out of the box? Or do I need an AGI script to do that? Also, if I want to call a number from an automated program in Asterisk and get the DTMF tones entered by the user on the other side, is there an easy way to do this? Best

Hi Inaki, > "Performant"... in terms of what. If the cost of copying the data > predominates over the computation time, maybe you didn't need > parallelization in the first place. Performant in terms of speed. There's no copying in that example using `mclapply` and so it is significantly faster than other alternatives. It is a very simple and contrived example, but

Hi Travers, Just an additional remarks to Michael's answer, if your S4 class inherits from R's basic types, say integer, the resulting object will be an INTSXP. If your S4 class does not inherit from any class, it will be an S4SXP. You can think about this question from the object-oriented framework: If one class inherits the integer class, what should R do to make all the integer related

Just throwing my two cents in: I think removing/deprecating fork would be a bad idea for two reasons: 1) There are no performant alternatives 2) Removing fork would break existing workflows Even if replaced with something using the same interface (e.g., a function that automatically detects variables to export as in the amazing `future` package), the lack of copy-on-write functionality would

I have a toy alt-rep string package that generates randomly seeded strings. example: library(altstringisode) x <- altrandomStrings(1e8) head(x) [1] "2PN0bdwPY7CA8M06zVKEkhHgZVgtV1" "5PN2qmWqBlQ9wQj99nsQzldVI5ZuGX" ... etc object.size(1e8) Object.size will call the set_altstring_Elt_method for every single element, materializing (slowly) every element of the vector. This

Hi all, Here's what I have. I have a list of log-in times for users and how long their sessions were. user, login_time, session_min alice, 2010/01/01 10:00, 145 bob, 2010/01/01 11:00, 30 What I want to do is create a bar chart showing, in 1/2 hour segments, the number of users logged in at the same time. For example: 10:00 1 10:30 1 11:00 2 11:30 1 The only way I can do this now is to

I think it's worth saying that mclapply() works as documented: it relies on forking, and so doesn't work well in environments where it's unsafe to fork. This is spelled out explicitly in the documentation of ?mclapply: It is strongly discouraged to use these functions in GUI or embedded environments, because it leads to several processes sharing the same GUI which will likely cause

Below is a toy alt-rep string example, that generates N random strings: https://gist.github.com/traversc/a48a504eb062554f2d6ff8043ca16f9c example: `x <- altrandomStrings(1e8)` `head(x)` [1] "2PN0bdwPY7CA8M06zVKEkhHgZVgtV1" "5PN2qmWqBlQ9wQj99nsQzldVI5ZuGX" ... `object.size(1e8)` Object.size will call the `set_altstring_Elt_method` for every single element, materializing

Hi; I am in the process of planning a PBX/Voice mail system for a business with an ISDN phone system and somewhere on the order of 12 internal phones. The ISDN system appears to be a Primary Rate Interface, though this may be irrelevent because receptionists answer all inbound telephone calls before possibly transferring via the PBX, and most calls do not get transferred. Telephone use

Hi all, ok, I just instealled the dovecot 2.0.0 release, and the latest mercurial pigeonhole source. All is well, except for a particular sieve rule that may not be working right. It is a simple rule that looks like this : require ["fileinto","imap4flags"]; # rule:[Past Due Notices] if allof (header :contains "Subject" "Account Past Due Notice") {

Do you mean this occurs when traffic is passed over an IPSec tunnel or that it occurs anytime a tunnel is use on a machine that also is passing VoIP traffic (outside the tunnel)? I assume you must mean over the tunnel but I am curious...

Hi, ok, I've compiled it a few times, and made sure all of my settings are correct, but the QUOTA is not appearing in the opening CAPA that comes with the greeting. I have it configured in the dovecot.conf like so: protocol imap { mail_plugins = quota imap_quota } and I can see when turning debugging on that the following is spit out when starting : Starting DovecotILoading modules

Hi all, ok, after looking at all of the posts that I've found, and trying numerous settings, I am a little stumped as to how to set up the deliver program with qmail to get everything correct. Ultimately, I really don't want to do a lookup of the home dir if I don't have to. I'd rather specify the stuff in the .qmail-user file for that particular user to avoid the extra step. In

Hi Timo, ok, I have a large 2.07 NFS setup, and I have been monitoring error messages to make sure I catch things, and I've come across a lot of messages that come in pairs and look like this : Dec 01 17:48:35 lda(paul at xxxxxx.com): Error: write(/home/mailboxes/data/301/paul at xxxxxx.com/Maildir/tmp/1291254514.M620308P83269.mta2.scaledsystems.com) failed: Permission denied Dec 01

Hi all; I have been searching for an answer to a question that a customer asked me and I have only found a few older answers. So, wanting to find out if anyone has any experience with this issue and can help provide me with some advice. I have a customer which is strongly interested in using Asterisk as a PBX. One of the core requirements, however, is that the system MUST be able to

Travers, Great to hear you're trying out the ALTREP stuff, good on you :). Did you mean the get_altstring_Elt_method? I see the code in size.c within utils that grabs each element, but I don't see any setting (and the setters are noops currently anyway they just do things the old way). One thing we have to decide is what object.size means for an altrep. I tend to think it should mean

Hi Timo, ok, using the latest 2.0beta6... I can't figure out the settings for the log file to have the correct permissions. When the log file is created, it is created owned by root and 0600 permissions, which doesn't allow the lda to write to it if I use different users and groups for that main config... If I then chmod the log file to 666, then everything is happy, but again, if that
