Society mailing list. -- Darren Duncan

Addendum #1: The meeting is on Tue, July 3rd.

Addendum #2: FYI ... for those of you who are driving to UVic take 
note that half of Ring Road is now closed, and unfortunately that is 
the half starting from the Henderson entrance and all the way to 
Finnerty Rd. including parking lot #1, so make sure you give yourself 
enough time to walk through the whole campus. Nearest parking lot is 
probably behind the MacLaurin building.

RCSS meeting announcement:

Talks
----
Dr. Kui Wu (Guest Speaker) -- Wireless Sensor Networks
Adam Parkin -- Gem Cutter and the Open Quark Framework
----

Meeting Location
----
The usual.
ECS 104, UVic, 7:00PM.
This is the last lecture-hall to your left on the ground floor when
entering the new computer science building from ring road.
----

this month's RCSS meeting will feature Dr. Kui Wu, a networking
professor at UVic.  Dr. Wu has been kind enough to provide a preview
of his presentation:

Recent progress in wireless communication and Micro-ElectroMechanical
System (MEMS) makes it feasible to build tiny wireless sensor nodes
that integrate sensors, processors, memory, and wireless transceivers
within the size of several cube centimeters. Such tiny sensor nodes,
when clustered together, automatically create highly flexible,
low-power wireless sensor networks (WSNs) with numerous new
applications ranging from environment monitoring, building control
systems to smart entertainment devices that adjust audio and video
quality based on changing environments. Over the last several years,
WSNs have become one of the major driving forces for technology
innovation, and substantial research and development efforts have been
devoted to this new technology from both academy and industry. In this
talk, I will introduce current progress and applications of WSN
technology, including the merge of sensors, actuators, wireless mesh,
and the Internet. At the end of the talk, I will try to predict the
day after WSNs and try to convince you that the story in Michael
Crichton's science fiction, Prey, is actually very close to reality.


See you all there,
Peter van Hardenberg

Subject: [VPM] Perl 5.9.5 has been released
Message-ID: <p06240800c2b598324c5a@[192.168.1.101]>

FYI,

The latest 5.x bleadperl has been released, 5.9.5.

Obtainable at: http://search.cpan.org/~rgarcia/perl-5.9.5/

It has been 11 months since 5.9.4.

AFAIK, 5.10.0 is slated to come out in 2 more months, this September. 
(I hope that is early enough for Apple to make it the system perl of 
Mac OS X 10.5.)

While I tend to be conservative, I intend to start using 5.9.5 now in 
my own development, for the first time, whereas previously I was 
using the latest 5.8.x for stability; I anticipate that 5.9.5 and 
later are now "stable enough".

I think that Perl 6 will take quite a bit longer to become production 
ready.  I would say, minimum 1 year, maximum 2-4 years for Perl 6.

But meanwhile, you can get more of the Perl 6 goodness in Perl 5.10 
this september than you could get in 5.8, and 5.10 shall be quite 
production ready.

Not in and of itself.  Perl 5 will have a 5.10, 5.12, etc regardless 
of when Perl 6 comes out.

BTW, I am still under the impression that 5.<odd number> releases are 
development releases, and 5.<even number> releases are the stable 
versions.  Unless that policy got changed without my noticing, I 
probably wouldn't use 5.9.anything, certainly not for a customer.

That is all true, 5.9.x and 5.11.x et al are experimental releases 
and shouldn't be used in production.  However, part of why I made 
this announcement is that I now consider 5.9.5 to be stable enough to 
use on my own development machine.  The 5.9.x series is feature 
complete and has no test failures, and has already been tested 
against much of CPAN; now it is just being further stabilized. --

hi all

does a reverse traceroute have the same path (in reverse of course) and 
number of hops and the same times as a normal traceroute?

eg. I want to create functionality where the http/proxy server would adapt 
to the connectivity performance of the client.

what perl modules are available for this?


Thanks in advance for your attention.

Looks like you've got Net::Traceroute and Net::Traceroute::PurePerl 
and even a POE component.

Are you hoping to get a stack trace from a regular perl script?  Are you in
doing object oriented programming, or web development (mod_perl)?  What sort
of performance range are you looking at?  What is too slow, and what is
acceptable?

I usually use the Carp module classes to give stack traces (confess, croak):

http://perldoc.perl.org/Carp.html

I believe that Carp is now internal to Perl, and it is mature, but, as with
many object oriented modules, there is some overhead involved when using
them.

There is also Dave Rolsky's Devel::Stacktrace:

http://search.cpan.org/~drolsky/Devel-StackTrace-1.15/lib/Devel/StackTrace.pm

Usually, when I want a stack trace, I am debugging, but I see your question
is concerned w/performance, so I am assuming that you want a dump to a log
someplace while the script is executing, and so the traditional perl
functions die and warn, probably aren't much use.

A perl profiler can help w/monitoring performance with scripts.

Charles,

Thank you for your response.

performance is an issue... it is for a web application, using a "mod-perl 
like daemon" process.

I am not going to be logging , eg. writing to disk, but storing the 
log..(array) in memory, then processing it at a later time. the data will be 
piped to another daemon process.

I dont want to be tracing every single call, but only calls I specify, eg. 
basically the structure (classes/methods, etc) of my own code.

also can I trace method calls from another thread, outside of the main 
thread?

I hope I have given you enough info for you to help me.

Thank you very much for your help so far.

-Jeremy A.

Depends what you mean by "too much".  Tracing will affect performance 
significantly.

Usually Devel::Cover or Devel::SmallProf will do what you want.

Consider Log::Log4Perl then.  I don't think this is going to be 
easy.  You'll hav to add a line to every method you want to trace.

>also can I trace method calls from another thread, outside of the main thread?

I don't understand.  The tracing will be in the code, so it will trace 
from whatever thread it is in.  You can't write something that will 
poke at another process or thread to see what it's doing.
