Not sure where I gave you the impression that perl, as a common ground for measuring language skills, is a good filter. Measuring one's language skills is of use only for gauging if the candidate might be useful to fulfill, also, the short term needs (which, usually, is to maintain/extend/fix an already developed solution). Measuring based on language skills is of only a cosmetic use from the point of view of hiring a long-term asset for a company. I didn't mean to say perl is "syntactically tough" or somesuch and hence its a good tool for interviews. Nope. I only meant to say this: Perl (or C, for that matter) doesn't lay out things on a plate. Perl requires understanding of core OS concepts before one can build real world applications for use in a production environment. PHP, Java, etc., OTOH, makes it infinitely easy for anybody to program and build seemingly real world applications, allowing all sorts of people to write all sorts of things and still get away with it. In Java, it is the VM that externalizes problems, as though, it is someone else's to handle. I meant to say, thus, if you come across a perl programmer who has built real world applications, chances are their fundamentals will be strong (which, of course, you'd be testing in the interview). Their fundamentals are strong because the language forced them to rethink their approach at every juncture of their own skill development. That said, likewise, one also comes across a whole bunch of "perl scripting" people who have not written anything more than 300 lines of relevant code... but then, again, it is very easy to spot them. > IMHO, the problem isn't with Java/Perl, its a problem with your > question paper / interview panel.

In my definition, A good programmer is one who, with the given circumstances, writes a code that optimizes readability, time and space complexity and maintainability. Anyone who tries to showoff their skills, by writing cryptic logic, is surely a villain in my team. There would be trade offs at some situations. For example, if you try to look at the Kernel Source Code (Linux of course), there are a few^H^H^H many places where the code is written in ASM. But, the comments above it would give the "C" equivalent of the ASM code.

It would be better if we choose the right tools for the right purpose. PERL/ C++ / Java have inbuilt libraries and constructs for different purposes. So if in their solution space, they find that "A" is very repetitive, they build a library/construct for that. If PERL thinks "A" is not the problem, but "B" is, you get a different building block in PERL. So, when you use PERL/Java/C++ you should know what building blocks are available, and what aren't. Then fill the gaps with your brains. A house can be constructed using wood, clay, clay bricks, hollow block bricks, steel and glass, etc... The problem is same. The solution space is different. The problem that needs to be addressed by the developer differs. He will have a different set of problems to solve in each of the solution spaces. As I said in one of my previous mails, A language is just a language. Its your ideas that become programs. If I allow any North Indian Politician to contest in elections in Tamil Nadu, would s/he not talk a few words in Tamil? Frankly, its not very different in programming languages.

I waited around to see if there are other interesting topics, but since nobody has posted one, here is my proposal: On Fri, Dec 2, 2011 at 4:15 PM, Shrinivasan T wrote: > Topic > Description > Duration > About the speaker > Links to read > If there is sufficient interest, I'd like to talk about "Producing and recording music with Jack" in the _next_ meeting (not the Dec 10th one). Description: Jack is a Virtual Studio framework for GNU/Linux. It fits nicely with the Unix philosophy of "Do one thing and do it right", allowing stand alone applications to model and perform the role of real-world equivalent instruments and devices while providing a robust platform to allow them to work together in real time. Jack models a real studio - so people familiar with studio technology will find it easy to relate to Jack. The Corollary is that to get accustomed to producing / recording music wih Jack, it is important to understand studio terminology. There are patchbays and it is possible to 'connect' the output of one virtual instrument / device to one or more. It is even possible to patch the output of one application to itself to produce interesting end results. There is even a global clock that controls all these instruments and let them all start / stop / synchronize in tandem. You can pipeline audio streams through effects processors, mix them, master them even over multiple computers over netJack. Jack is cool and above all, it is Free Software. Jack supports most high-end audio hardware out of the box and copes with low end hardware pretty well. An interesting tidbit: Jack project contributed to the Linux kernel's real-time abilities significantly. This talk will be a hands-on demo of Jack running the Hydrogen Drum Machine, ZynAddSubFX Synthesizer (based on the many revolutionary hardware synths), Qsynth (real-world sound samples based synth), RoseGarden (MIDI recorder / sequencer), Seq24 (pattern based MIDI sequencer that can be used as an Arpeggiator) and Ardour2 (Digital Audio Workstation with inbuilt mixer and effects processor pipeline). There would be no feeling of a "finished" sound without the many LADSPA plugins that make producing music with GNU/Linux real and fun. However, setting up jack can be a bit tricky. Though, in the recent months, atleast the latest and greatest of Ubuntu makes jack work "almost" out of the box. This talk will mostly cover 1. the primitives of electronic music 2. how jack models the same. 3. setting up jack 4. a little jamming with jack! What's needed? - I will bring my laptop and a USB-MIDI cable - need one of you to kindly find a keyboard with MIDI out (preferably not a complex high-end MIDI controller that requires reading a 150 page manual :) ) - need one of you to kindly find some sort of decent speakers (my laptop's speakers don't work) Duration: 60 minutes About the speaker: I'm a self taught music student for the past 7 years. I'm also a self-taught student of computers and depend on computers to make a living. I used to learn music (mostly carnatic and a bit of western) and had always been looking for a means to use my GNU/Linux based computer to record and learn. I'd always wanted a home-studio setup for the purpose of learning and recording what I learn. Jack made it possible to finally make my dream of setting up a home-studio come true. I expected to have "real" hardware in my studio and I thought, what an expensive hobby that would be! but I now have a "real" powerful desktop that costed me about 5-7 times lesser than a "decent" entry-level hardware-based full studio setup. I run AVLinux 5.0 on my studio desktop where I only use it for the purpose of producing and listening to music. Though there are a couple of other alternatives, including Ubuntu Studio (which I tried a while ago and found it not as out-of-the-box as AVLinux), Studio64 (tried, didn't even work well), etc., that all bundle jack and the plethora of music software that work with jack.

[Ilugc] [TIP] perl tutorial II (conditionals and looping)
We will see conditionals and looping.
To begin with perl does not have the switch statement found in other languages.
There is also no break and continue. Instead you have last and next.
Most of perl's conditionals are written using the regex construct:
if(/\d/) {
} elsif(/\w/) {
}
Here is a complete example.
$ cat i.pl
$users = 'foo,boo';
if($users =~ /\d/) {
print "digits\n";
} elsif($users =~ /\w/) {
print "alnum\n";
}
Regular expressions are usually acted upon the default $_ special variable.
So if(/\d/) actually means if($_ =~ /\d/).
Anyway now let us focus on the core conditionals and looping facilities in perl.
We have already seen the if() condition before.
We have also seen the foreach()/for() iterator.
for() is just an alias for foreach().
$ cat i.pl
foreach($i = 0; $i < 10; $i++) {
print $i . "\n";
}
Replace foreach with for and it will work the same.
We have seen the iterator idea already.
for $var (1 .. 100) {
print $var . "\n";
}
Same thing can be written as
for(1..100) {
print;
print "\n";
}
Here we again see the default loop variable $_ working.
It is good not to focus on perl's tricks to begin with. Do things the
formal way.
We now have seen the if() conditional and the for() looping construct.
Of course we have while() and we can simulate switch statement too.
We will see that tomorrow.

As a trainer, if you think perl is a good language for pedagogy, there are more stricter languages like C that can help.

I would partially agree with you that object oriented programming (the way it is done in Java) makes it possible for anybody and everybody to "get their job done" - which is also bad from the point of view of building teams and organizations (very difficult to gauge one's programming / analytical capabilities). Perl, that way, is a very useful tool for filtering out and hiring the best.

[Ilugc] perl OO
I am really not competent to talk about OO since Object Oriented programming is not something I am excited about. The only language in which I have used it is in Perl. And in CGI I use it a lot without actually knowing that I use OO at all. It does not force one to think much, it is not pedagogical and abstruse or confusing. It just gets your job done. So we may have a lot of subjective arguments here. Essentially my point was that in lower level languages like C++ and Jave and other OO focused languages OO becomes very involved and difficult(at least for me). But in perl it is nice and simple. But you have to read a lot and the information is scattered in several different man pages. $perldoc perlobj $ perldoc perlboot $perldoc perltoot $perldoc perlbot and so on. Also $ perldoc perlmod In the case of perl object orientation is implemented using the module and package concept. We will cover that later. So all I am saying is that one can have any number of subjective views. We should end up learning something useful that is all. I think it will be impossible for me to remove opinion from fact or vice versa. Please take my tips with a pinch of salt. I don't think even wikipedia is free from prejudice.

How are you saying this? From my understanding Java's primary design goal was to ease the implementation from OO design and in the begining Perl was to kludge error reporting.

[Ilugc] [TIP] perl tutorial I
Yesterday we saw some perl code/opinions and history of perl.
Today we will see more.
As I said perl grew up in the UNIX world with UNIX command line tools
and shell scripting
ideas. You can even look at it as a shell scripting language on steroids.
As we go along you realize that if you know UNIX well already you are
well on way towards
becoming a perl expert.
grep,tr,sort everything is also there in perl as functions.
$perldoc -f grep
And you can easily call shell executables using
$output = `grep girish /etc/passwd`;
system("rdate time-a.nist.gov");
or
exec("cp /etc/passwd /tmp");
Though you can have OS bindings and interactions with any language,
scripting or otherwise with perl
the UNIX ideas are all over.
You can open a UNIX pipe just like you open a file.
Perl's modules provide you with functions that the shell commands do
without doing a fork(), exec() and
calling a shell executable which is very costly.
And contrary to what people think and believe perl only slightly
improved the regular expressions already
used in the UNIX world in shell globbing and so on.
Look at man flex. You find nearly all the perl regex ideas.
And perl code is not really intuitive. It has its defects along with
its strengths.
But just like we have an inferior language like English which cannot
match up to Tamil whichever way you
look at it, perl though not as great as others is popular, successful
and enjoys support.
So I use it , I spent time learning it and continue to use it.
Let us get back to explaining the foreach() array iterator from yesterday.
Before that few general comments about scripting and high level languages.
High level languages all consider the default type of a variable as a
string. Of course you have to
quote them, but you don't have strong typing as in C.
In fact it is the weak typing of variables in which they can become
integers or strings depending on the
context that make scripting languages so easy to deal with.
Scripting languages also make several difficult things easy. Due to
perl's strong UNIX affiliation you can
do a lot of things you have been doing in the UNIX world using pipes
and various command line tools more
efficiently in a better programming language like perl.
And network programming and many cool things that C does perl can too.
Without the difficulty and pain.
It has object orientation and is a very good OO language unlike C++ or
Java. Perl give many choices and
as I said, in typical UNIX style, it is very well documented, it has
accurate example code in the man pages
and the CPAN modules/third party libraries are of very high quality.
Overall we get a very pleasant experience with perl.
As part of these multifaceted conveniences and powers, we also have
what is called as array iterators.
This is also found in shell scripts and certainly in languages like
Python which has advanced forms of the same idea.
For instance, instead of using for() loops like in C for iterating
thro' array elements, we say
foreach $var (1,2,4,5,100) {
print $var . "\n";
}
Or this:
for $var (1..100) {
print $var . "\n";
}
It is very similar to the shell scripting concept:
for var in `cat /tmp/file`
do
echo $var
done
See?
These are called iterators.
We also see two more of perl's superb features.
One is the range operator. 1..20 to print numbers from 1 to 20. Cool.
You can use them anywhere we want.
And the string concatenation operator ".".
$o = "first " . "second" . "third";
will simply add the three strings(strcat() in C).
Then you have another great feature.
$foo = "imposition " x 40;
will write the string "imposition" for you 40 times.
Okay we have seen enough explanation and English till now.
>From tomorrow we focus only on code samples.
I will illustrate whatever I have been trying to say in English so far.

Thanks Mr. Arun Khan for your valuable suggestions on OpenSuse 12.1. Hope this information will be useful for those who are using OpenSuse 12.1 and those who want to make a try :-) -- Regards, Prasanna Venkadesh PuduvaiLUG (puduvai Linux Users Group): http://puduvailug.wordpress.com/ FOSS Jobs all over India: http://fossjobs.in ___ ILUGC Mailing List: http://www.ae.iitm.ac.in/mailman/listinfo/ilugc
[Ilugc] US has become a dangerous place for software development: RMS
RT (Russia Today) yesterday conducted an interview with Richard M Stallman, the founder of Free Software Foundation and the writer of the world's most advance license GNU GPL. RT asked readers to ask questions and then they would pick questions for RMS. http://www.muktware.com/news/3056 We asked two questions on RT's Facebook page and both those questions were presented to RMS. Muktware: Do you think USA is becoming hostile to innovation and competition as the companies like Apple and Microsoft are gaming the system? RMS: I have to point out that innovation is not my highest value. Human rights are my highest values. So I don't to get into the dialogue that treats innovation as a primary goal. With software patents the US has become a dangerous place for software development, including innovative software development, because when a program is innovative, that means it has some new ideas in it. But it also has lots of well-known ideas in it. A large program combines thousands of ideas. So if you have some new ideas and you want to use them, in order to use them you have to combine them with a lot of other ideas that are well-known. And if you are not allowed to do that because those other ideas are patented, you can't use your new idea. Muktware: How much control should the USA have over the Internet? RMS: No more than anyone else. I don't think it will be safe to have any global control over the internet. because we could predict that that global control will work for the empire of the mega corporations and would attack human rights.
