Messaging is just degenerate RPC?

I hate to use expletives to describe this guy's writeup since he's done a remarkable job with the cajo project. But I couldn't help laugh at this claim of his:
"Messaging is degenerate RPC: If you want messaging, by all means, go for it! It is a very useful technique. However, it must be seen for what it is; degenerate synchronous RPC: i.e. a tiny subset of the functionality that is possible with distributed objects."

It's good to be passionate about the remote invocation approach that your project uses, but its plain daftness to make silly claims like "this is the right way of implementing a distributed system". For the same reason, I won't pass a judgement. I'll let you consider a few points and arrive at a conclusion for yourself:

1)Could google's apps have scaled with synchronous RPCs?
2)What's better for a high perf distributed system - blocking on a synchronous RPC call or continuing processing until the response to a remote message interrupts you on another thread?
3)In a supply-chain kinda web app, once you receive order confirmations, do you make RPC calls to place orders for shipping each component, or simply queue up the request in a message queue (which a "down-stream" app could just read off and dispatch orders)?
4)Ever heard of "decoupling" applications?
5)What's easier - a 1:n messagetopic (in JMS) or a similar rpc invocation on 'n' remote objects?

I could give you a zillion more examples like this where async messaging scales much better. And "what if the underlying implementation uses rpc's" or "email is just rpc" are very lame refrains: you're generalizing an implementation approach adopted by a messaging system used by humans and extending it to apply to those used by fast applications relying on asynchronous messaging. How're you so sure that the 2 must be implemente similarly?

Classifieds with Google Base

Firstly, my apologies (to no one in particular) for the looong hiatus . Sheer laziness. Anyways, on to the main topic - did you know such a thing existed- Google Base ? It's a place to post/search for classifieds of all kinds. Yes - all kinds. Been discovering quite a few low profile changes with the goog goodies. The bookmarks for example - they now let you bookmark like delicious does, while giving you the choice of keeping bookmarks private or sharing them. Real cool.

Every great work, every great accomplishment, has been brought into manifestation through holding to the vision, and often just before the big achievement, comes apparent failure and discouragement.

Mining at Kudremukh:Why the SC should stand firm

It was quite disheartening to see the Karnataka Bar Association appeal to the SC to reconsider its decision on the KIOCL in Kudremukh. The landmark judgment of the SC that asked the KIOCL to close operations - based on the evidence of immense environmental damage caused to Kudremukh’s pristine rainforests by KIOCL’s operations - promises to be an example in eco conservation. Yes, I can only imagine the plight of the 20,000 individuals who have been displaced as a result. But remember, it’s the KIOCL’s responsibility to find them a suitable alternative. After all, it was the most profitable government owned mining undertaking in the country. It’s time for the cash-rich government to now find alternative employment for its employees. I hope the CM Mr.Dharam Singh succeeds in his endeavor. But, at no cost should the mines be allowed to reopen and cause any further damage to the environment. Just to refresh one’s memory:
1) The Kudremukh range is home to three rivers – Bhadra being one of them.

2) The reclusive Lion tailed macaque, whose numbers are fast dwindling, is found primarily in the Bhagavathi range of Kudremukh.
3) The KIOCL, since its inception has damaged hectares of virgin rainforests of this range and believes that creating rose gardens or eucalyptus groves amounts to “reforestation”.
4) Tons of iron ore sludge was leaked into the forests due to the company’s oversight.
5) All rivers starting at Kudremukh are now witnessing increased levels of contamination in various forms. – Check this PDF.

Speaking of point 2 above, one might ask, “Why does preserving any animal species assume such importance? We just need enough green cover, right?” – Wrong.

There is such a thing as ecological balance, wherein the flora and fauna are equally important to each other’s (symbiotic) existence. Take out one from this feedback loop and the other vanishes. And if the forests vanish, so do the rains (remember, the ocean currents are not the only ones that bring us rainfall) and the rivers that are fed by them. With that ends our source of water, energy and the climate control that the Western Ghats are - which brings me to the point of our flawed understanding of “Human rights”: as much as the 20,000 in Kudremukh have a right to 2 square meals a day, future generations have a right to clean air, water and food – which only a balanced ecosystem can guarantee us for centuries to come (I’m just quoting from articles (this and this) by Bittu Sahgal – and he should know?). So, it’s imperative that we do our bit (for our own good) to preserve what is a basic necessity for a flourishing civilization (and economy). When you see a greedy businessman plotting to wipe out our future in the name of “development”, stand up in whatever way you can against such a force. Express your opinion through the media that matter, lend your voice to the few frail voices that now dare to oppose the “development” cartel and lend your spare time for a worthy cause. Don’t expect someone to lead you by the finger and answer questions for you like “Where do I start?”

If we have the will to stand up & be counted, intend to lend a meaning to our self-centered lives, and amount to something, we will find the means to achieve a worthy goal. Merely saying, "I love nature" or "I'm an avid trekker" amounts to zilch. What have you given back to the forests that have played host to yourinnumerable treks all these years? So, start now, write about it in your blog, write to people who you think can have a significant influence on decisions in future, persuade people, contribute through your time (or money - one can subacribe to magazines like sanctuary wherein the subscription fee will be used for the field work of these organizations).

(Meanwhile, our cities choke on their own excesses… that’s another story, another blog)

Pet peeves at work

Some things I have no patience for in a work environment (more relevant to the indian scenario):

Type 1]"I'm taking a break => so must you"

This is the number one kind of pest in the Indian corporate setup that you can come across. People who keep peering at their screens for hours at end, finally decide they need a break. So, what do they do? Barge into someone else' cubicle, nose around, pass comments in general, play the fool and expect the other person to reciprocate. Remember, that person has no work except to entertain this moron.

Type 2] "What's he doing to get an edge over me?"

This kind of a pest has NO RESPECT WHATSOEVER FOR ANYONE'S PRIVACY. Has to keep peeping into everyone's screen, finding out what great tech article the other guy is reading (& getting an edge over this moron?Who cares? ) They constantly have this insecurity that they're losing the edge & the other guy is going one up over this loser. So, whether you're writing code ("it's our product's code that he's keying in - i have a right to see it too"), reading an article ("this guy refuses to waste time on orkut like i do. Doesn't he have a life?") or composing a mail("ah, finally"), he must look into your screen. My response is generally one of these:

1)That's none of your business sucker.
2)You call yourself a professional?
3)"Etiquette" - ever heard of it?
4)"Self respect" - not heard of this either?
5)I'll tell you when you're allowed to play sherlock & look over my shoulder.
6)Do your own thing
7)Spending a year in the industry doesn't make you "experienced". It takes mental maturity to understand how a professional work environment functions. This isn't your college. Time to grow up/
8)(And if push comes to shove..) Go fly a kite.

Type 3] Hypocrisy

The same pest who has admirable qualities 1] & 2] also talks of how the Indian IT industry "isnt't professional enough compared to that in the US of A " - look who's talking.

The bottom line -you need to mature dear, and mature fast. Poke your nose into other' biz only when you're asked to. Don't impose your schedule, your mood & your state of mind on others. Do your own thing. If your feeling bored, go to the rooftop,get some fresh air or even better, fly away from there. But learn to be professional, for christ sakes. This isn't your damn college!! Get the message, yes?

The Niagara thunders down in full force

The enormity of Niagara's processing capability & it's power efficiency are simply overwhelming every other system in it's class built to date. The amount of buzz it's deservingly generated is quite amazing, to say the least. And HP, as usual, has shown it's class by resorting to FUD. Alan Hargreaves has responded fittingly. Some more information on the niagara boxes & the records that they've been setting. btw, Sun's open sourcing the design & validation code for the UltraSparc T1 (Niagara). More links:

Capturing Screenshots in GNOME on Solaris

Ever tried capturing a screen shot of a menu in an UI application on GNOME? Notice how the menu gets de-selected (or loses focus & disappears) as soon as you hit the print-screen button. The way to get around this is to use the gnome-panel-screenshot command at the console with the --delay= option. This switch makes the screen capture occur automatically after the specified delay, by which time you can "prepare" your application UI for the screen shot.
