my experiments with technology: Playing with R

http://tech.sraghav.in/2015/02/playing-with-r.html

My experiments with technology. Sunday, February 1, 2015. Since early 2013, when I got to know of possible online learning for R through www.coursera.com. I have been a fan of this language. For me, laying my hands on RStudio. Was the best thing that happened to me around the statistics learning curve. The tool makes your R learning curve so much more easy and possible, the college could never do that. Subscribe to: Post Comments (Atom). My experiences, probably. Rails App For Existing DB. Simple theme&#...

my experiments with technology: June 2012

http://tech.sraghav.in/2012_06_01_archive.html

My experiments with technology. Thursday, June 14, 2012. It was in 2010 that I had the first taste of hadoop/hive. Back then I was still using hadoop 0.20 and was doing a proof of concept for a customer, who wanted to see if hadoop can be a solution for their problems. The experience is awesome as usual, and it reinforces my belief in the fact that hadoop ecosystem has a huge role to play in the computing industry of tomorrow. 2 you have to launch hive in a particular way, as a service. (. Also, hive on ...

my experiments with technology: Weighted trust graph for authentication

http://tech.sraghav.in/2015/02/weighted-trust-graph-for-authentication.html

My experiments with technology. Monday, February 23, 2015. Weighted trust graph for authentication. During the hackathon (discussed in earlier post), I met with Gary. He had come in to be play mentor, but since he couldn't devote enough time, ended up being a guest. After engaging Neo4J in few meetups and understanding the database a bit, i was contemplating using Graph databases for authentication. It might have consequent applications in fraud analytics too, where graph databases are used already[1].

my experiments with technology: May 2015

My experiments with technology. Thursday, May 7, 2015. Hadoop Meetup on the sidelines of Strata Hadoop Conference - Part 2. Read part 1 of this here. Day 2 of the meetup was equally exciting, if not better. Lined up were talks from Qubit and Google, William Hill (a surprise for me - more later on that) and then PostCodeAnywhere, all very exciting from the synopsis. From my own knowledge of stream processing, which is not significant in anyway, i could relate to many similarities with IBM’s info sph...

my experiments with technology: January 2013

http://tech.sraghav.in/2013_01_01_archive.html

My experiments with technology. Saturday, January 12, 2013. Teradata TPump vs MultiLoad. Was doing some research around Teradata's load utilities and found some useful info on Teradata forums. Loads data to TeraData from a Mainframe or flat file. Multiple tables can be loaded in the same MultiLoad. Up to 20 INSERTS, UPDATES, or DELETES on upt o 5 tables. There can be NO - Unique Secondary Indexes (USI), Triggers, Referential Integrity or Join Indexes. Duplicate rows are allowed. Locks at the table level.

my experiments with technology: Hadoop Meetup on the sidelines of Strata Hadoop Conference - Part 1

http://tech.sraghav.in/2015/05/hadoop-meetup-on-sidelines-of-strata.html

My experiments with technology. Wednesday, May 6, 2015. Hadoop Meetup on the sidelines of Strata Hadoop Conference - Part 1. Not being able to make it up to the Main conference (Strata Hadoop London 2015), the evening meet-ups were the consolation pieces of getting in touch as much as possible. Last evening, on day 1 of the conference, I ended up attending one of the meet-ups. It was particularly useful for me, for couple of reasons. Subscribe to: Post Comments (Atom). My experiences, probably.

my experiments with technology: January 2014

http://tech.sraghav.in/2014_01_01_archive.html

My experiments with technology. Thursday, January 30, 2014. Removing ports from an existing mapping - Do's and Dont's. Recently, a colleague called in for an issue that he was facing with an Informatica mapping. Let me recreate that situation here -. What this gentleman did was to remove the connections for those ports from the source qualifier onwards. That saved him from changing and re-importing the source definition. Posted by Raghvendra Sharma. Friday, January 24, 2014. This is an interesting one&#4...

My experiments with technology. Sunday, February 9, 2014. Programmatic interaction with Facebook data. I am a self-anointed tech junky, and therefore no one should be surprised that i took up this challenge couple of hours back to build a brand new routine to get data in/out from/to facebook using a popular and open source Data integration tool, called Pentaho. Which turns out to be based on the old Facebook API and prompted me to look elsewhere for the right way of working. Monday, February 3, 2014.

my experiments with technology: Hackathon - Fintechathon

http://tech.sraghav.in/2015/02/hackathon-fintechathon.html

My experiments with technology. Tuesday, February 17, 2015. A hackathon is a hack. Wherein many people are invited to attack problems around a theme. I recently attended a hackathon over the valentines weekend. Organised by StartupBootCamp Fintech, it was attended by about 100 people. Many ideas, many teams, some partners i.e. corporates with their own challenges. We, had the other way round. all of us were teamless and therefore put together as a team. We had no idea to start with. As a resu...Finally w...
