>Leaving IBM…

March 31, 2011

>Having worked with IBM for few months I have decided to move on. It has been a great experience to work with the world’s no 1 software company. It is very special as IBM is celebrating its centenary as an organization.

I have been working in smart energy initiatives of Application Innovation Services division. Theme of my work at IBM is “Smarter Grids” (Follow the link to see what is a smart grid!)

I would take this opportunity to wish all my colleagues “All the best” until we cross our paths in this small IT world sometime, somewhere!

>తత్త్వ చింతనం

March 30, 2011

>ఉత్తమాతత్త్వ చింతాచ మధ్యమా యోగ చింతనం |
అధమా మంత్ర చింతాచ తీర్థభ్రాంత్యంऽధమాధమః ||

The lowest step is going to holy places. Having visited “tirthas” one gets in touch with holy men and their blessings.
The next better step is “mantra chintanam” – repetition of a mantra. i.e., japa
Even better is practice of yoga.
The Best is the vichara into the tattva i.e., the tattva of oneness!

>Integration – Data or Information, Application

March 22, 2011

>Having written a post on topological differences (EAI vs ESB) of integration long time back, and management approaches (centralized vs distributed) I am making an attempt to look at approach in terms of data integration vs application integration.

We have slightly touched upon this subject of Application Integration on one of the earlier post – Binding energy in software systems.

So, what is data integration? A typical Extract-Transform-Load – ETL, data migration, Change Data Capture – CDC, Master Data Management scenarios are classified as data integration. There are several platforms from big and small vendors to achieve this. (IBM InfoSphere/DataStage, Informatica, Microsoft, Oracle, Pervasive have suites/products under this head)

How is this different from traditional Application Integration? Application Integration focuses on integrating business process supporting the information workflows. Data Integration focus is primarily on the propagation and synchronization of data across the enterprise system landscape sometimes spanning into Cloud..

When the volumes are high, a data integration based approach has an advantage; If the process/workflow complexity is high and orchestration is needed to achieve the integration then one should look for an ESB/SOA style integration.

Enterprise Data Integration platforms are comparably similar to EAI platforms in their nature of technical architecture (hub/spoke based EAI topology) with a ETL hub that loads the data into a warehouse.

Of late, the buzz is toward real-time data integration based on CDC etc., let us see how it goes and changes the game!

>గురు గీత

>यत्सत्तया जगद्सत्वं यत्पकाशेन भायुतम् ।
नंदनं च यदानंदात् तस्मै श्री गुरवे नमः ॥
by which existence the world appears; and by which light the world is bright; and by which bliss the world derives happiness; to that GURU I bow down.

मन्नाथ श्री जगन्नथो मद्गुरु स्त्रिजगद्गुरुः ।
ममाऽत्मा सर्वभूतात्मा तस्मै श्री गुरवे नमः ॥
My lord is the lord of the universe (jagat); my guru is the guru of the three worlds; my atma is the atma of all the beings; I bow down to such lord = guru = self!

अखंड मंडलाकारं व्याप्तं येन चराचरम्
तत्पदं दर्शितं येन तस्मै श्रीगुरवे नमः
“akhanda mandalaakaaram” in which the whole of living and non-living beings appear, that word “tat” has been shown to me by the GURU. I bow down to such guru.

देहे जीवत्वमापन्नं चैतन्यं निष्कलं परम्
त्वं पदम् दर्शितं येन तस्मै श्रीगुरवे नमः
That which entered the body, that “jeeva chaitanyam” which is never tainted by anything, that word “tvam” has been shown to be by the GURU. I bow down to such guru.

अखंडं परमार्थं सत् ऐक्यं च त्वं तदोश्शुभम्
असिना दर्शितं येन तस्मै श्रीगुरवे नमः
akhandam, paramaardham that truth and body, this are one and the same that is shown by the word “asi”. Such word is shown to me by the GURU. I bow down to the Guru.

Having said that, a small word of caution.
गुरवो बहवस्सन्ति शिष्य वित्तापहारकाः
दुर्लभ स्स गुरुर्लोके शिष्य संताप हारकः
guravah, bahavah, santi, sishya, vitta, apahaarakaaH.
durlabhaH, saH, guruH, loke, sishya, saMtaapa, haarakaH
There are lot of gurus who take away the wealth of the sishya; it is indeed difficult to get a guru who will take away the “worldly misery” of the sishya.

— From skanda purana; GURU GEETHA.
(Most famous “gururbrahma, gururvishnu gurudevo maheswarah, gurussakshaat parabrahma tasmai sri gurave namaha” is also from this chapter of Skanda Purana only.)

>Divine Mother appears in her four aspects as one’s own mother, sister, wife and daughter. Respecting each of HER aspects in proper way is the due worship to the Divine Mother.
