Achieving rewards our brain (dopamine circuitry and such) in ways to reinforce learning way better than 'organized' learning attempts.

Flipkart is probably going IPO soon, this may be an interesting change to a long recurring trend (where the only kind of IPOs that happened in India in the IT sector were services companies which mostly sold indian labour, much like what happened in the 19th century). The many emerging indian startups are thinking radically different - for once, as I may have mentioned here earlier, they are open to hiring anyone with any background, irrespective of their academic performance, provided they can DO WORK (read: solve problems, writes good code, understands fundamentals well and can learn). Afterall, what's more to keeping pace with the world of computers than constant self-learning? ___ ILUGC Mailing List: http://www.ae.iitm.ac.in/mailman/listinfo/ilugc ILUGC Mailing List Guidelines: http://ilugc.in/mailinglist-guidelines

What more, using this approach you will be able to write code once and be able to run it on multiple mobile platforms without having to write code specific to each platform. To me, this is a huge win - especially when I would just like to test a product/concept and refine it. It is also a huge win because from the beginning you get to develop a web-accessible version of your application that can be accessed even from a desktop machine. This inclusiveness, I like! I found http://trigger.io to be the most pain-free way to achieve this using the HTML5/CSS3/Javascript approach - the reason this works is because most modern mobile platforms have a WebKit or equivalent that supports HTML5 specifications. The typical Conventional way to achieve this is to use PhoneGap / Apache Cordova project - but I have found setting up PhoneGap to be a pain (actually I couldn't - I gave up after 1 hour of trying) and trigger.io Just Worked! Trigger gives a python tool that can run on GNU/Linux. The tool will submit your code to trigger.io servers, generates a build out of it and downloads the build. Then you can 'run' the build. If you have a device connected, it will load it into the device or, where applicable (like with Android) trigger will start the emulator if you have installed the Android Development Kit. However, for iOS, you will still need and iOS device like an iPad or iPhone. There are other alternatives to trigger like sencha or even many so called 'do-everything-on-the-cloud' services like Tiggzi, etc., I haven't tried those (I tried sencha and found their 'free' version too restrictive to try out what I wanted to do and ExtJS is a whole framework I'm yet to wrap my little head around) and I found Tiggzi and their ilk to be targeting developers who don't want to write any code. If your intention is to develop games or other such multi-threaded stuff, then a Javascript based app may quickly turn into a bottleneck and will have visibly poorer performance (unless you are a JS guru or have a team of JS gurus... like Rovio*). In such a case, the best bet would be to develop a native iOS (or android) app. However, if all you need is a decent user interface, then Jquery Mobile / Zepto / etc., can be of help and may be a smarter thing to do especially if the 'solution' you are providing involves the Internet (ie., the mobile device is just the user interface while the 'brain' of your app sits on the cloud). * It is worth noting that the famous AngryBirds also has a HTML5 version but it still doesn't work as smoothly as the native version of AngryBirds (unless one possess a high spec device). So, writing native apps has its uses - but I'm assuming 80% of typical app development needs can be met using the HTML5 approach. YMMV.

For this reason applications like Zabbix lure you into a trap - they have all these features you know you want, but they come with a 'technical debt' due to the various design decisions already made for you (such as to use an RDBMS backed data store ( or embed SQL everywhere in the application without a second thought :) ) ) which will bite you at certain scales of operation even if it gets you started. The problem with IT is its critical and when you become dependent on something, you don't want to change it. So it may be a smarter thing to get the basics right the very first time and do some work ourselves than go shopping for an end-to-end solution. For example, one could use mondemand + LWES to setup a programmable, distributed event monitoring/management framework. LWES + mondemand helped us have decentralized, need-based monitoring and IT automation solutions at a startup where I last worked. Once the basics got setup right, we could setup a dashboard like the one you're asking for in a couple of days - all simply because we figured this entire stuff will be data-intensive and decided to use a Cassandra based custom data store for storing metrics. Similarly, extending our in-house applications to 'instrument' new metrics into it was also quite easy. Doing this the Zabbix way or Nagios way would have been royally painful since we'd be trying to 'fit' stuff into the monitoring app than make the system flow its natural course. cheers, -Suraj -- Career Gear - Industry Driven Talent Factory http://careergear.in/ ___ ILUGC Mailing List: http://www.ae.iitm.ac.in/mailman/listinfo/ilugc

A careful design can make scalability easier by writing it in C and do an glue-scripting, rather than Ruby/Python. When we talk performance, let's talk about what exactly we mean by it. Most applications are never bottlenecked on the CPU and are most of the time waiting for I/O. In such cases, the so-called overhead of running a dynamic language like perl/python/ruby far outweighs the drawbacks. Writing good code in C is probably twice as hard as writing good code in perl (and probably 10x as hard as writing good code in python / ruby). By good, I mean, maintainable, readable and modular code. That said, when it comes to shell there is one problem I've faced a lot: Since shell scripts leverage external utilities (like cat/sort/cut/etc.,) that can be realized only after a 'fork()' and since most people today prefer to run stuff on VMs, the performance of fork system call on certain VM hosts is unpredictable and bad. Sometimes it may take several seconds for a seemingly harmless process like cat to instantiate. I'm not an architect who can talk about scalability/performance of a big or enterprise level application, just an amateur programmer, but in my opinion, whatever complex the problem, a well defined split-up and writing tools for each split can scale whatever level we want. Want a proof? just look at git. It doesn't suck!! because it was not written in Python/Ruby, its a bunch of C programs which can be used as commands in bash (as well as in any language). what you say about this? with your so called Python/Ruby scalability? git is a fairly limited and well defined problem area that involves mostly string manipulation. Also, its open source (and open source software quality _usually_ is better than enterprise grade software, IMHO). Consider something more complex and event driven, like your typical enterprise grade HTTP application that is under a constant pressure of meeting deadlines and people whose, shall we say, social conditioning is not necessarily wired for the most elegant solutions but instead for those that just work and those that give them recognition in their social circle (read: career).

[Ilugc] Secure/Trustable running of command on untrusted box
Hi, I have a completely untrusted remote (sand)box (stranger has root on it). I'd like to trigger running a program on that box and like to get the triggered program's output from that box. My problem is in trusting the output of this program since it (or the layers above/below it) could have been tampered with by the said root user. How can I trust something coming from an untrusted box? Context: The stranger will be challenged to solve a problem on the box (say, apache fails to start, we'd like the stranger to fix it). To measure whether the stranger has solved the problem, I'd like to run something on the box (ex: ps -ef | grep apache) to validate if the end state has been achieved. However, such a naive 'ps' test can easily be cheated using a rootkit or possibly using other simpler means of reverse engineering / cheating. My current approach is to only extract part of the needed information from the box and do the validation from outside (ex: by comparing against a reference / control / ideal solution). But not all challenges will fit into this scheme (the example outlined above cannot be done this way since we'd like to actually see if such a process is running, however, for instance, I can certainly challenge a person to write a fibonacci series generating program on the machine and be able to confidently validate that program's output from this machine. In this case, the truth being validated is universal, whereas systems specific truth (such as whether mysqld has been configured correctly or not) can be found out only by probing the machine).

Hi Arun, On Tue, Aug 21, 2012 at 11:18 PM, Arun Venkataswamy arun...@gmail.comwrote: I am trying out a FreeSWITCH based VoIP system. There is a considerable, around 1.5 seconds lag on the audio. Some improvement was seen when the server was switched from an Amazon EC2 small instance to an Amazon EC2 medium instance. Considering India specific customers and usage, is it reasonable to assume that I will get substantial improvement by moving to a dedicated server (quad code, 4GB RAM) based geographically inside India? Can anyone throw some light on this? Also would like to get recommendations to an India based dedicated server provider. Thanks. I didn't fully get your explanation here: Please correct me if I'm wrong: I'm assuming you have a FreeSWITCH based system in India which talks to the business logic server hosted out of EC2. Although Amazon claims the IO performance to be moderate for both Small and Medium instances, I've personally noticed significant variations in the small instance IO performance due to contention for resources (more small EC2 instances on the same machine, lesser medium EC2 instances on the same machine; medium instances are pooled together and you may never usually find medium and small together on the same real servers) Some things you may want to check: 1. Is singapore your EC2 availability zone? If not, it may be worth moving it to singapore to see a significant improvement in latency between your indian FreeSWITCH service and the 2. Instead of a dedicated server, you may want to look at the High I/O instance: http://aws.amazon.com/ec2/instance-types/ (I'm not sure if this is available in the Singapore availability zone; I haven't personally used high I/O instances) 3. Monitor your app and the system's performance. Is Network I/O your bottleneck?

We want to monitor continuously: a. All the Linux boxes and the services running on them, b. The performance (and history) of the Java applications too. We are exploring the best ways to monitor the whole setup including alerts and automated restarts etc. We are primarily from a development background with only basic admin experience (basic bash, installations, tuning etc). I have researched all the usual suspects: Cacti, Nagios, ZenOSS, Zabix?.. JMX seems to be very popular for tomcat/Java. What are your recommendations for handling this scenario? What are the pros and cons of various tools and approaches? Please do share your thoughts on what will be a good solution. All live examples will be very welcome in educating us. All the tools you've mentioned above are systems level monitoring applications. While they are also useful, easy to setup and also needed, they can only give you so much information about your applications by measuring information about the stuff that is outside (like the JVM's / the OS's internals). The problem being that the application we care about is treated like a Black Box. This may be useful if we had a well behaving / well understood black box. But usually we don't - even if we do, it changes. I've found the following general pattern of practical Dev Ops problems occur frequently at work: Scenario#1: * The ops says From insert system monitoring tool, we see that network I/O has increased since last launch. We believe that performance can increase if our application reduced excessive fetches and instead chose to cache or preload * The dev says Well, you guys seem to be running insert operational monitoring / management tool on *your* machines for management. It is not the problem of our application. We are not at fault! We have done nothing that increases reads. We deny it all! (replace network I/O with anything that cannot be pin pointed) Scenario#2: * The ops says From insert system monitoring tool, we see that there was a CPU spike. Any idea what happened? Here are the application's logs from the time * Dev says We don't know which function/component/part caused it. We will try to reproduce it in the lab. (and usually, no lab can be as hairy as reality) At the last startup I worked (which is no longer a startup and was serving close to half a million requests per second as of 6 months ago), we zero'ed in on mondemand to do white box metrics measurement to tackle the above mentioned frequently recurring scenarios. See http://mondemand.org/ . We chose LWES as the transport, but that was based on our setup. YMMV. mondemand requires instrumenting one's code. mondemand also requires one-time investment in effort towards collectively brainstorming about what metrics we want to measure and how we will measure it by putting the app and business in focus. But once done, the pay off is self evident due to the black box turning into a 'white box'. In terms of the above mentioned system tools (zabbix, nagios, etc.,) - it is my opinion that the incremental advantage over each other may be negligible since almost all of them provide extensibility (plugins / extensions). The distinct advantages of mondemand are: 1. when the app is Java and the system is Unix, there is a large gap created between the dev and the ops. Unix'y things like signals, controlling I/O streams (logging), controlling priority or even measuring memory used, etc., are difficult to achieve. Yes, JMX can help, somewhat, but again JMX is a means of measuring/controlling the Java system (not the app). 2. As mentioned above, white box measurement is the biggest gain. 3. App can react to outside events - not only within the system but also networked events (ex: if you restarted the DB, the DB restart script could emit an event and the app can react by reestablishing the connection) Yes, a small performance penalty for all of this - but, IMHO, it is worth it. :) cheers, -Suraj -- Career Gear - Industry Driven Talent Factory http://careergear.in/ ___ ILUGC Mailing List: http://www.ae.iitm.ac.in/mailman/listinfo/ilugc
[Ilugc] Tools for simulating network issues
Hi, I'm looking for ways to simulate network issues. Specifically, the following scenarios: IP - packet loss TCP - connection establishment takes time - connection established, but server application is slow / unresponsive - piled up connections / running out of sockets The end goal is to expose learners to these problems and be able to show how tools like netstat or collectd's graphs will behave upon each scenario. I don't have multiple real machines, I have 8 VMs running inside a reasonably powerful quad core box. The box has only one network card. The learners do a graphical login to the box over LTSP and ssh into the various VMs. Theoretically, I do see a way to achieve these by developing relevant netfilter modules - however, I don't know if any ready made modules exist or how easy/time consuming it may be to develop a netfilter module, especially given I want the simulation to be highly controllable. Am I right in my approach? Any suggestions / pointers to tools will be helpful. thanks, -Suraj -- Career Gear - Industry Driven Talent Factory http://careergear.in/ ___ ILUGC Mailing List: http://www.ae.iitm.ac.in/mailman/listinfo/ilugc

Moving to a thick-client infrastructure is only externalizing the problem (perhaps, it will also get solved since now nobody will depend on the network or the centralized server). But, let's get this straight: You are moving to a cost-wise, maintenance-wise and moving-parts wise a more complex and expensive infrastructure (FYI: Hard disk prices have doubled in the past 6 months). The problem you've described might be most likely related to computing / disk bottle necks... but you may have to look into some hardware usage statistics (does I/O top out when these folks are reading their PDF? ... and maybe also, Are there Viruses on your Windows Server(TM)?). Try and meditate over how you can best solve the current problems you're facing in the existing thin-client based infrastructure. Its a matter of identifying bottle necks and clearing them up. Once you've cleared them, you've scaled and you've also learnt the recipe to scale (atleast some of the ingredients in the journey thus far). Centralization is where the world is moving to - because today, it is easy to do (really beautiful software exist, virtualization is reality) and it makes a lot of sense in today's world (with rising costs of materials and energy). It also makes common sense because most end user PCs don't get used to its designed capacity most of the time. They idle and waste away. If you'd like to take to virtualization here is your chance :) I'd think its still a hardware-wise / energy-wise cost effective thing to do to consolidate. Think about it: The Internet is moving in that general direction too (move stuff to a centralized place where it makes a lot more sense to take good care of it in bulk). End user computing at an office environment is no different, just that its all local. Thick clients Messy and I guess there is also something very fundamentally wrong when people hate the presence of the System Administrator at their desktop PCs taking away their productive time.

So 10 x ~Rs.4000 == ~Rs.40,000/- just for your hard disks. I too had a similar need for 15 client systems for educational purposes. I decided to do away with hard disks and go with the thin client model not only due to price but also for other ease of maintenance, ease of expansion and consolidation reasons. Yes, it requires care on the server side but as Arun Khan and others have already pointed out on this thread, a combination of solutions (Virtualization + RAID + LTSP) can give you a better deal in terms of maintainability as well as cost. I now use openVZ for virtualized server access - students ssh into it and do all sorts of experimenting there. or 2. Intel Atom D525 based system. D525MW isn't in production anymore, according to ritchie street vendors. You may want to double check this information. I too wanted D525 (because it has a gigabit ethernet onboard) but settled with D425KT (only 10/100) because that is what was available. Also, D525 is dual core, whereas D425 is single core. Not that it matters so much for thin clients, but we never know how we'd end up using our hardware in the future! Heard that Atom based system are not really facinating to work from few users. Can someone throw light on this. Atom based systems are pretty good for thin clients. Also, by using a kill-a-watt someone measured 22W on an atom based thin client - so that makes two thin clients consume roughly about 1 tube light's worth power :) You get to save so much on stuff that conventional solutions tend to externalize (electricity bills, cooling needs, UPS, etc.,) edubuntu's in-built LTSP server solution is just _out of the box_ (as opposed to what someone here said earlier that LTSP will require shelling out extra bucks for someone else's consultation[1]).

In this sense, I must agree with the author that the term Open Source is quite similar to the term Hinduism - arbitrary, open to interpretation and confusing to the uninitiated. The term Open Source only refers to software whose source is available, not on whether we have the rights to use it, maintain it and distribute it freely as a community. Which is why, to refer to software that is By the people, For the people and Of the people the term Free Software is better than Open Source.

[Ilugc] My thin client experience
Hi, Thanks to all the folks who gave useful feedback to help me find a suitable thin client for my business' needs. I just finished taking iTalc on a test drive. iTalc is quite literally a beautiful educational tool. I wanted to use the power of computers to visually explain concepts but yet didn't want to put up an economically and energy-wise expensive projector or a fancy large screen TV. iTalc filled that very need by providing a means to control and transmit to the desktops of the LTSP clients. My needs were: 1. GNU/Linux friendly thin clients that work in an LTSP environment. 2. Low on power consumption: saves power bill, saves cooling needs, cut down need for a big UPS. 3. Low on desktop foot print: Thin, Small, Simplicity is what I was looking for. Simply because I don't have a very large space. 4. Self Maintainable (ie,. no horribly-designed-products-with-3-year-warranty). 5. Gigabit - just so I can be happy to know the network is not my bottleneck. What I reviewed: 1. Ncomputing: Bound to their proprietary software - sucks to be forced to use non-LTSP. But Ncomputing was way cheaper and it did lure me since they are known to support Linux. 2. Userful: Super simple, Beautiful, Works with most - but I got skeptical and leaned away. 3. Panache: Awesome line up of products though, most cost effective thin clients are proprietary. No way to get a look and feel - gotta order and be happy with whatever I find. I didn't like this very aspect. The good part about panache was its openness in letting folks purchase their cabinets alone. But their cabinets are about 2 times more expensive than the cheapest vanilla Rs.900/- cabinet. 4. Used PC: I tried. I gave up because I didn't want to be living with a nightmarish infrastructure made up of a diverse mix of PCs of all sizes, ages and makes. Plus, most of them came with stuff I didn't want - like hard drives or an AGP. But all disadvantages aside, this seemed to me to be the most cost effective route- I could have gotten a box-monitor based setup for Rs.5000/- but that saving will swell other running costs. 5. DIY thin client: I so wanted to do it. but I wasn't sure I was going to find the time. Little did I know, though, that this route will consume 3 man days in finding the truth behind excellent sounding sales promises by just about every vendor on Ritchie St. The review: IMO: All the factory made products didn't score on the price and the maintainability front, except Zotac's ID-series. But its availability in India was a problem. Used PCs weighed low on all my needs except that of self maintainability and low cost. DIY seemed like the only choice left to be explored... and this exploration is more than just calling up people ;) So I was left with the bar on power consumption and foot print. The only way forward was to come up with the configuration and shop for suitable cabinets that are small and available in the market for closer inspection. This is what I ended up with after arriving at Chennai and loitering around Ritchie St for 3 days. Thin client configuration: - Intel D425KT - 2G DDR3 - 15.6 LED TV - Zebronics Genesis slim cabinet - KB+Mouse The cost of this setup turned out to be about Rs.9,100/- though if one wasn't as specific about desktop space usage or energy usage, a setup as cheap as Rs.6,000/- could have been achieved using old CRTs instead of the LED that sank 3.3K. The server and its karma: The LTSP server used to be a Home Audio Studio DAW in its previous birth. I chose this because this was the best box I had on hand. I chose edubuntu 11.04 because LTSP worked out of the box (My erstwhile studio sports an i5 Quad core with a DH57DD motherboard. I upgraded this rig to add 8G more RAM and bought two new 500G SATA 2 drives for RAID). I also test drove the power of the jack audio framework and realized it is possible to use LTSP to _do_ stuff like what real studios do (one person doing the drums, one singing, another doing the bass, another playing a real instrument and one mixing it all together live. One Helluva Free Software Orchestra it can be.

I have not yet understood how map() works. It is a functional
programming concept.
map is a means of transforming (mapping) an array into another array. The
arguments to map are:
1. function which will take one element at a time and return one element
2. the array of elements
As an example, if one would like to calculate the square of numbers in an
array and store them in another array, one can use map to do it as follows:
@x = (1,2,3,4,5);
@y = map { $_ * $_; } @x;
or simply
@y = map { $_ * $_; } (1, 2, 3, 4, 5);
When map invokes the provided function (first arg) it is called with $_ set
to each element of the array and is called one time for each element in the
order of appearance of its arguments. Let's use map now to also print the
array @y:
map { print $_ . \n; } @y
1
4

16
25
Here is an exercise to the reader: Using a combination of regexes and map,
read a HTML file and turn all its a href=(.*?)(.*?)/a into a hash
where the URI is the key of the hash and the marked up text (anchor text)
becomes the value. The following is a sample test input string:
$string = EOM;
a href=/blahGo to blah/a and a href=/blah/searchlook for all the
blahs/a... and here is a a href=/multimulti
line
emnested/em HTML markup
/a
EOM
In a lot of ways perl is messy and with a syntax that is so odd that
it is often called
The write once forget language
In other words perl is used for quick and dirty jobs.
I'd once again request you to stop demeaning the stuff you're trying to
teach (or thrust your impartial views onto a public forum like this). Why
would anyone want to learn something that is, according to your narrow
understanding, is worthless?
If you think something is tough, it will remain tough and unapproachable
(because the problem of 'toughness', etc., is in your mind). If you're full
of your own preconceived notions, it is very difficult to change it unless
you're willing to throw away those notions and then explore and learn about
it (there is nothing to lose when learning, except time :) ).
Think about it, programming a computer was not any friendlier back then,
yet, that is what paved way for generic abstractions that allowed us to
build cooler stuff on top. Perl too, if you approached it this way, can be
effectively used to abstract away problems and build generic solutions on
top. But you should be willing to invest time in abstracting and designing
your code thus. If you expect a scissor to do what a chainsaw can (and vice
versa) then it is not the tool that is at fault.
Perl on the other hand is a high level language. It is a scripting
language; which means that it is a
language used to express your ideas in a language that looks like English.
This could be said of python but perl is not even half as elegant.
An illiterate will (almost always) write horrible poetry. This is a highly
subjective (and highly inflammable ;) ) bait. Perhaps you're judging perl
by your (or your peers') inability to write elegant code? A sword, to a
Samurai, is more elegant than a pistol.
Why was I not forced to learn Python deeply? But perl is something I
use everywhere. This should give you a hint.
For that matter, why were you not forced to learn even perl deeply?

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 tshriniva...@gmail.comwrote: 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.

This also creates a problem, when you frame a question that is applicable for PERL and not very applicable for Java. We have to understand that programmers are not a single breed. Everyone specializes/has interests in particular areas.You can't compare a OS programmer, with a Game developer, with an enterprise application developer, with a mashup developer (What is a Mash up?). Am sure the Mashup developer would have the least clue of what it takes to sort objects in Java/ Perl. Agreed to every thing you say. 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. As I said earlier, a language is independent of analytical skills. Why not frame your questions in such a way that they don't have to write programs, but provide you with algorithms instead? Absolutely agree. But tell me, from your experience, do you have a perfect interview panel who all ask relevant, core testing questions? :) -Suraj -- Career Gear - Industry Driven Talent Factory ___ ILUGC Mailing List: http://www.ae.iitm.ac.in/mailman/listinfo/ilugc

And perl's UNIX focus lies in its manpage format for documentation unlike python's help(module) perl's documentation is not in the manpage format. Perl's document is written in the POD format (for Plain Old Documentation). It is possible to obtain the documentation using perldoc (not man) and pod easily gives way to turning the same documentation into any format. Yes, its a big advantage, but its not just man pages. Given man's popularity and familiarity, for the sake of convenience, some package maintainers choose to also turn the pod documentation into man. style, though every language has OS bindings perl is a direct copy when it comes to regex, its Could you please explain what you mean by perl is a direct copy when it comes to regex? IPC and so on. It is nothing but UNIX in a new flavor. Perl is a language with an interpreter on top of Unix-like OSes (and windows and mac and many others including real-time embedded OSes). Perl is not an OS. the OS is below perl and does all the hard-lifting, but perl, as do all languages, attempts to let the programmer write an elaborate recipe of achieving something by manipulating the OS underneath, without us having to know about the internals (of interacting with the OS). So it is confusing when you say that the driver is the vehicle, ie., perl is the OS. [snip] Depending on whether the lvalue is singular or plural(scalar or array), the RHS will be assigned as the length of the RHS or the list in the RHS itself. Err... For instance, if you write, $sca = (1,3,4,5); You will see that $sca contains 4. $ perl -e '$sca = (1,2,3,4); print $sca;' 4$ $ perl -e '$s = (1,3,5,6); print $s' 6 Oops. Its not the length of the array. Its the last element in the array. But if you do this: @a = (1,2,3,4); you will be able to assign the whole array. This can trip many people, even experienced programmers. One can even argue it is a bug. Everything requires a certain approach to learning, learning to deal with a dog is very different from dealing with a dragon. But there are obvious differences in end applications for the two. The question is whether you have learnt that approach fully well and can explain the same to everyone. It is not very helpful to make sweeping statements that only point out problems without providing solutions.

Not just India, world over, perl is not as widely used as, say, Java or Python because perl, for writing anything significant, requires mastery over the language's internals. Without experience and/or careful thought, one can completely ruin or make one's code horribly difficult to maintain if they don't know what they're doing with perl. But that is fast changing - with Moose (and other emergent frameworks built on top of Moose (like Catalyst MVC framework)), perl is now an extremely fast paced environment. At least in LUG, the perl knowledge seems woefully poor. Perhaps because no such survey (we know of) has been conducted in ILUGC to conclude whether the knowledge is there or not ;) Unlike shell scripts and makefile variables, perl always requires a variable to be prefixed with one of $, @ or # before it. % is used to prefix hash variables, not #.

[Ilugc] Oilsville: a new open source game
Hello, I hacked up a game to illustrate Peak Oil[1] and christened it Oilsville. My hope is that people will now be able to grasp the phenomenon of peak oil - how any finite resource (or even a renewable resource stripped faster than it is being replenished) will reach a peak in how much volume can be extracted and eventually start declining, no matter what improvements in technology are made. The premise of the game is simple: There is a new oil field waiting to be exploited. You got a rig (with configurable size of the straw) which will start pumping out oil. Every well will start yielding lesser and lesser over time as the underlying geology dictates that the pressure must decrease. Larger sized rigs, as with reality, requires larger amounts of energy to operate and are also costly to operate. The only way to ramp up production is therefore to drill more. But the catch is... the more you drill, the closer you are to peaking production and you'd eventually reach a point where no matter how big your rig is, you cannot increase production! But given this is Oil Money, rest assured you'll be a millionaire oil tycoon! Feel the frustration as you ramp up your fight against Entropy! :) Check out the screen shots: http://peakoilgame.com/scrshot.html Download: http://peakoilgame.com/download.html The game source is perl + SDL. perl pod documentation exists but there is lot to be desired in the code documentation area. I've tested this on Ubuntu (karmic). The source ships with a script that builds the deb and doubles up as a (hacky) non-ubuntu installer. I'm seeking volunteers, code contributors and hackers for the following things: 1. Port to Facebook - the core game is SDL agnostic so it should be quite easy to port, I believe. I'm specifically looking for hosting a Farmville contender (hence the name Oilsville) :) 2. Port to windows - I'd ideally love to have a windows installer, much like what the Frozen Bubble[2] folks have done. 3. Port to Flash - since I have peakoilgame.com[3] registered, I'm looking for a flash version that can be played online - hosted on peakoilgame.com but also available for free download. 4. writing test cases, documentation, etc., (you know, the part that developers typically avoid :) ). ... of course, I'm willing to get surprised by new, creative applications of the code. The code is general enough to be used for any peak anything types game/simulation.

[Ilugc] [Pointless Statistics] Peak Linux
http://bit.ly/linpeak The number of registered Linux users on counter.li.org has peaked[1] in 2005. If the charms of Open source and Free Software still apply and with growing population of tech savvy crowd, I see no reason why the registrations on counter.li.org must go down. This is, of course, the sum of registrations from each country. A good old friend (and an ILUGC member :) ) pointed out that correlation is not causation. I agree. But I wanted to know if the list admin will be willing to help mine up data from the list member registration stats/logs. We can conclusively see if there was a Peak in the most number of users adopting to Linux and if that trend is declining. I don't have data to back this claim but my gut feeling is that modern ways of computing are radically changing and Linux is finding a Niche and settling down. Is Linux getting adopted as a Desktop OS as much as MacBooks seem to become affordable to people? Or has the use and throw culture killed the Art of Unix OS maintenance?

While providing a reliable internet connection over rural India still remains a challenge, the further challenge is maintaining these so called kiosks. The main problem is high frequency of power outages and management of resources. The answer to this is in my original email (sorry if that was long and made you skip through sections!). The basic idea being, they merely borrow books from this library like they would borrow from any library. They don't even have to know a thing about computers - not even the fact that the 'books' they're reading / editing are stored on the Internet. Infact, the 'computer' in the library need not even be 'on' all the time. But this is all only the library's job. The NGO worker ensures people get awareness and thinks towards benefiting his locality. He teaches them and helps them with information useful to the locality and their life styles. He is not just a 'librarian'. Of course, this needs smart and dedicated NGO workers - not just people who can deliver food / materials. But I'm confident we aren't short of such people.

About our team: Our team deploys and ensures smooth running of the Search
Database content generation systems. Ensuring smooth running is a big task by
itself and that involves writing a lot of software tools.
Given the large scale of our setup, traditional problem solving techniques need
to be approached from a new set of angles simultaneously. To give you an
example, a tiny cluster (of a few dozen machines) wouldn't be affected by
failing hard-drives because probability of disks failing on a given machine is
low. However, put thousands of machines into the picture and we now have one of
these improbable events happening pretty frequently! We have about a dozen disks
failing every day and so it definitely pays to find out the causes on a
continuous basis.
Now, we need a few more passionate people who not only have a zeal for operating
large scale systems but also have Automation in their blood. Want to join us?
You should have solid software operations skills with the drive to fix issues as
they arise and the knack to identify needed tools and build those tools
too. Your duties will be focused on:
* Working with the rest of the team in knocking off ad-hoc maintenance tasks
* Having and using the wisdom to take a step back and ask How can we avoid
doing these repetitive maintenance tasks?
* Contributing independently to build tools that keep the search content
building systems up and running
* Communicating by ways of documenting and mentoring in an open-source-like
Development Environment.
Needed Qualifications:
* Proficiency in Perl, Shell Scripting
* Very good knowledge of building web-based dashboards (CGI-Perl, PHP, etc.,)
* Strong understanding of Unix systems and tools
* 3+ years of experience developing Unix tools (in Perl / Shell)
* Strong commitment to jump in and fix issues as they arise
* Decent understanding of Networking concepts
* Excellent trouble-shooting skills
* Excellent Written and Oral skills
* A BE/BS in CS/EE or Equivalent
