Subject: [Rehovot-pm] Rehovot Perl Mongers meeting reports
Message-ID: <d8a74af10912011251l6ec0b4c8o6e03548dfc5fc7e9@mail.gmail.com>

hi,

since the Perl Mongers meeting in Rehovot 2 weeks ago I was quite busy
at a client and installing my new desktop computer so only now I managed
to finish the report about the meeting.

In short - I was late to the meeting, and I am sorry for that.
My plan to have some Matlab and some PDL and then to start coding did
not work out.
We had two nice talks about Matlab but I could not introduce PDL at
any reasonable
level and most people prefered to have a chat rather than coding.

On once of the coming meetings I hope we can go on with PDL and we can
also start the coding part.

Shlomi has already written a report in Hebrew:

mine is in English: (well sort of )

regards
    Gabor
ps. We are still looking for speakers for the coming meeting in
Rehovot and we are still looking
for a place in Tel Aviv/Ramat Gan.

Could you give us use-cases? Who needs this and when?

BTW will that be able to provide a solution for this?

Would there be interest in a lecture on Asynchronous IO with Perl?
It would include an introduction to non-blocking sockets and IO::Lambda.

It sounds interesting.
It would be great if you provide also some real-life applications.

Case:

You want to write a program that access a number of web sites
simultaneously. 

Let's suppose that there are 1000 sites to be accessed and depending on
the site, different actions need to be taken. 

Writing a program for each type of site and forking them is the obvious
and probably easiest solution. If there are more than a few sites,
forking becomes very expensive and slow. 

One solution is to only have a single thread, open all the sockets in
that thread and then process them, each according to it's own logic.

==============================================================
And now for the problem you asked on perlmonks. Reading between the
lines, I assume that Padre needs to run a debugging perl session in the
background and interact with it. If that is the case, there you could do
this:

Open a server socket in Padre and wait for socket events.
Run perl in debug mode with RemotePort defined as an option. If you look
at perl5db.pl you will find a description and the implementation. 
Now you should be able to interact with it.

Regards,

Peter

Yes, very much so. +1.

I haven't looked at IO::Lambda yet - just at POE. There's also PEVANS'

I have already written the client that talks via the socket but I still have
not figured out how am I going to hook up its events to the GUI.
At least not on Windows.

There are the wxSocketBase and wxSocketServer classes.
There should be any/much difference between the Linux setup and the
Windows setup. Could you elaborate on the problem?

Real life applications:

1. If you have a very large mailing list and want to send the emails as
quickly as possible.

2. If you have a cluster of computers each with various logs, and you
want to monitor those logs and perform actions in real time. This might
be more applicable to bio-informatics.

As you point out, there are a number of ways of doing asynchronous IO.
Given the number of packages, deciding which path to take becomes a
non-trivial choice.

The difference between Coro and the other choices, is that Coro is
threaded, and all of the other solutions are single-threaded. The are a
number of differences between writing a single threaded aysnc
application and a multi-threaded application. Threading means timing
problems, semaphores and the rest of the overhead that goes with
threading. Plus, debugging timing problems is hard.

Here is my suggestion. Like many of you know - I'm not a good speaker, but I 
still would like to volunteer in case no one else does. The topic of the 
presentation is:

http://www.shlomifish.org/lecture/Perl/Lightning/Opt-Multi-Task-in-PDL/

Note that I'm unhappy with the slides as they are currently stand. I think 
what I'll do instead is present the problem (using some new slides), give some 
data (which I'll make available online), ask for ideas how to implement the 
task using PDL, and then maybe let people implement it individually.

Shlomi, sounds like a good plan. If you could beef up the slides to
your satisfaction
then either you or someone else will be able to present the problem
and then we'll
have a task to implement during the meeting.

So the plan is that this will happen on the 22nd December.

1) It seemed to me that something like (a guess) 1/3 of the people present
at Rehovot pm last time had little to none experience with... perl !
So I suggest we plan a few (short?) talks about basic topics in perl (refs?
OOP?).
Personally I'd be happy to hear about XS, as it seems that using existing
C/Fortran libraries is always an important issue in scientific environments.
I noticed that there's PDL::PP, so a talk on this probably would also be
important.

2) Unfortunately, I can't attend on 22/12 (have to leave Rehovot around
19:00, maybe earlier).

   Cheers,
          AA

Hi all!

Sorry for the late reply, and for quoting Gabor here. I didn't get a lot of E-
mail due to an RBL SNAFU at my E-mail provider. <sigh />

Message-ID: <d8a74af10912160219o2d31b652o31b55da3a3c118b8@mail.gmail.com>

I am sorry for the delay in the announcement but I am having a
busy time wrestling with both clients and Padre as I would like
to make sure the debugger already works in the next version.

Anyway,

Hadar Levi agreed to give a talk about PDL::Indexing, which explains
the basics of  indexing and threading. http://pdl.perl.org/

I think I'll use some time to give you a deeper introduction to Padre.
I'll plan to look at
1) how the debugger was added (and by that time it should be past tense)
2) how to add a simple plugin.
http://padre.perlide.org/

If there is interest - as I'll ask on the spot - I'll give a short
introduction to perl. Either to everyone or to the smaller group
who are new(ish) to Perl.

After that we *will* have exercises.

Please RSVP to my e-mail address if you are planning to come.

Subject: [Rehovot-pm] The meeting of Rehovot.pm yesterday and Padre 0.53 has
	been released
Message-ID: <d8a74af10912230453o2fc82f29jfc8386835e903513@mail.gmail.com>

Yesterday on the Rehovot Perl Monger meeting I talked a bit
about Padre and mentioned that each menu item can now have a
'comment' that will show up in the status bar when someone is browsing
the menu items. I mentioned a lot of these are missing and that a simple
way to contribute to Padre would be to add these strings.

Then I went home and instead of sleeping I actually went through all the
menu items and added these comments. So that low hanging fruit is
now gone and all the strings are in the new release.

OTOH if someone wants to help it would be great if all these strings
were translated
to Hebrew as well...

regards
   Gabor
ps. following is the announcement of the new Padre version:

Subject: [Padre-dev] Padre 0.53 has been released
To: padre-dev at perlide.org


Thanks to everyone for this release of Padre.

Unfortunately I didn't get all the translations done due to some of
the work that Gabor did right at the end of the cycle caught out the
translators.

I'm hoping to have 1 release with a 100% translations done!? Might
call a "string freeze" to allow it all to be done.

Anyway, here's the release blurb:

This is my third release as release manager for Padre, I really did
have to change the heading!

It's been a busy 9 days since the last release. i spent a bit of time
chasing up our awesome Translators
?to make sure this release would see a complete set of translations.
The translators stepped up to the plate and a day before release we
had 4 green squares on the? translation status report.

Then Gabor found out how to add the tips in the menu to the status
bar.? While a really nice touch, the changes caught out the
translators.? I delayed the release for as long as possible, but
unfortunately not long enough to get 100% of the French translation.
Jerome missed out by barely 2 minutes.? Sewi (Sebastian Willing) only
just made it, so 100% DE made it into this release.

I'll see if I can't roll out a release with all our languages 100%? :)

OK, so lets get on with what has happened in these last 9 days!

New:
??? - Add initial version of a debugger using Debug::Client (SZABGAB)
??? - Landed new multi-resource locking subsystem. Many operations are now
????? prevented from refreshing the GUI multiple times. Startup, shutdown,
????? open and close multiple files, session changing all much faster (ADAMK)
??? - Ctrl-Tab behaviour is now configurable (SEWI)
??? - Reuse the comment field of the menu actions and show them in the
toolbar (SZABGAB)
?? - Added Preference setting to control autocomplete when editting a
script rather than
????? a Module.? (WAXHEAD)


As with any release not only do we see new items and functionality but
there are always a list of fixes.? Azawawi got busy fixing problem
bugs in Padre that caused bad behaviour with Padre crashing.

Fixed:
??? - Fix crashes when running refactor actions when there
????? is no document (AZAWAWI)
??? - Open resource searches now for user selections (AZAWAWI)
??? - The Open resource's OK button is disabled when the
????? search results list is empty (AZAWAWI)
??? - Fixed "Syntax Check" focus loss bug while switching tabs quickly
????? and a syntax error is in one of them (AZAWAWI)
??? - Help search does not block when loading a long help topics
????? list (AZAWAWI)
??? - Fixed missing mime type guessing that caused new Padre documents to
????? default always to Scintilla (AZAWAWI)
??? - Fixed Padre crash when closing a Perl 5 script tab quickly while syntax
????? check is on (AZAWAWI)
??? - Added "No errors/warnings to $project-relative-filename" to syntax
????? checker. (AZAWAWI)

See!! Azawawi was just unstoppable this release.? It's always great to
see people return to Padre, rolling up their sleeves and grinding out
the improvements!

Performance improvements:

Adam Kennedy got busy with some major changes to the core of Padre
regarding the way it handles internal locking and refreshes.? This
should see some improvements to the speed of Padre opening and
closing.

?? - Audited the startup process for database operations that either weren't
????? being done in a transaction, or were doing crazy bizarre things. Startup
????? is now noticeably faster (ADAMK)


And that's not all the changes.? You can always see what each release
brings with it and get a sneak peak of whats to come by checking out
the Changes file.

I'd like to thank everyone involved with Padre.? We often can be found
in #padre on perl.irc.org It's always a fun channel to hang out in, we
have some really clever people working on an IDE that I have come to
really enjoy using.

If you haven't tried Padre why not?


Pete.

Hi Shafik!

I'm CCing your message to the mailing lists where the people who took part in 
the meeting are subscribed to. Hopefully someone can refer you to someone more 
knowledgeable.

(Sorry for replying in English, but that's the working language of the mailing 
lists).

Shafik is interested in people who know about Matlab GUI design.

Hello Shlomi,

you've given me a link to the convention of people who are dealing with 
Matlab. I tried, but was unfortunately unable, to reach them. I was requested 
to subscribe to the site, but the subscription failed despite repeated trials. 
Due to the importance of the situation, I would appreciate if you can assist 
me in reaching any one of them.

Good luck, and if you can help Shafik, please do so.

Message-ID: <d8a74af10912300112n4a837f33l6e2faf5d6f1882d6@mail.gmail.com>

Hi,

finally I managed to understand how to update the website of Rehovot.pm via the
WebDAV interface the pm.org webserver provides us.

I took the site that was there, put it it a git repository, changed it
to be generated by
a simple script from some templates and pushed the whole thing to Github.

On the website http://rehovot.pm.org/ you can find instructions on
where it is on Github
and there is a README file in the repository explaining the process.

The new site already contains slides from previous talks, links to the
reports and
some of the scheduled talks.

If any you would like to patch the site, please use the repository on Github.

Related to that I think I'll use this examples to give an introductory
talk on

1) Template Toolkit
2) Git + Github
