Digium FXO Card
Hi,
I wish to know if GNUGk can work with * running as a gateway with the Digium
FXO card.
Kindly share your experiences in case there are some issues which one must
know before going in for such a setup.
Also, I've been reading about the DialTone detection capability by the
hardware in different countries. What are the issues with it?
Thanks & Regards,
Deepak

Which ADSI phones to buy?
I just need to buy 5-6 ADSI Phones.
I wondering which of these models to choose

I've reading this lists few months.
We are small company, that makes some system intregration, development and deployments in VoIP scene.
Completely under linux. Today i have 6 machines with asterisk, huge test base - including devices like AS5350, Audiocodes gateways,
ATAs, IP phones ...
Now is time to make a decition for including * in our future projects. Main goal for us is the Stability.

add only the 1st of May with POSIXct
Thank you Rui for your code.
I basically understood all your suggestions.
I am using an old version of R (version 3.6.3, installed in a server I am not allowed to control), and the new pipe operator does not work.
I tried to run your code without the "|>" operator, but I get an error when I use apply.
Could you please expand your code without the pipe operator?
Thank you again

Sum of columns of a data frame equal to NA when all the elements are NA
Should not the result be NULL if you have removed the NA with na.rm=TRUE ?

How to produce rainfall maps
Hi,
You might get more help from the R-sig-geo list, which is devoted to
spatial topics.
However.
The *.asc file is an ArcGIS raster export format. You should use
whatever the appropriate import commands are for your own gridded
rainfall data. If you have a different format, you might or might not
be able to import it directly with raster.
?raster will tell you more about the kinds of formats

How to produce rainfall maps
Fwiw the engine behind geom_raster needs explicit observation-per-row form
for input (with no structural normalization), so conversion to points is
perfectly proper here, albeit confusing in context. (It's closer to what
graphics devices actually use ultimately, but the expansion is laid out
very early in ggplot2 because there's no standard for intermediate forms.)
Cheers, Mike

Sum of columns of a data frame equal to NA when all the elements are NA
What do you mean by "should not"?
NULL means "missing object" in R. The result of the sum function is always expected to be numeric... so NA_real or NA_integer could make sense as possible return values. But you cannot compute on NULL so no, that doesn't work.
See the note under the "Value" section of ?sum as to why zero is returned when all inputs are removed.

Sum of columns of a data frame equal to NA when all the elements are NA
Surely the result of summation of non-existent values is not defined, is it not? And since the NA values have been _removed_, there's nothing left to sum over. In fact, pretending the the result in that case is zero would appear audacious, no?
Cheers,
Boris

No. The empty sum is zero. Adding it to another sum should not change it. Nothing audacious about that. This is consistent; other definitions just cause trouble.

Help, Ideas and Ready for use Solutions
Hi,
I would like to ask you for advice how to solve the following case:
I have a client (who happened to be my friend) and I have convinced
him that the IP PBX solution is much better than the conventional
telephone centrals (PBX). At the beginning he wanted to buy PBX
Panasonic, but at this moment he is waiting for my decision. Because
at the moment we are not so deeply familiar with these

Stable clock with 2.6 and without Digium hardware.
Anybody sucessfully got stable 1000Hz clock without Digium harware and kernel 2.6?
We need to consult some peoples how to clock asterisk stable with exactly 1000 Hz without much kernel/drives patching/tweaking.
Some test results we made so far:
2.6 with digium card - stable 1000 Hz.
2.6 with ztdummy - uses RTC and the clock is 1024, not 1000.
2.6 with some Realtime kernel patch - provides stable

DSP Coding
Hi,
I would like to find some way for hardware coding instead software
(using the Host CPU). Are there any PCI boards just with codecs (DSP)
or other way?

How to produce rainfall maps
Dear R users,
I need to produce rainfall maps using R.
I know that this is possible, I looked though the web, I found the example below reported (the author is Andrew Tredennick).
I would ask you if this is the most performing way to make rainfall maps; if yes would someone be able to give me an example of how file.asc and pointfile.csv should be? If no would somebody please show me another way

I see: consistency with additive identity. That makes sense. Thanks.
