How are the optimal end-points chosen from a CDN when content is served?

There is a lot said in the Internet about how Content Delivery Networks speed-up the delivery of static content to a website. Sure — there is a lot of sense in saying that servers that are in physical proximity to the end point (typically a browser) are capable of delivering content with lesser latency than those that are on another continent. There were some important questions that I did not ask myself when I used Akamai’s CDN (due credit to them for nicely abstracting these details away!). Off late I have been reading about Coral, a more open CDN in an academic sense. Read More »

Predicate Abstractions for Dynamic Languages

SLAM and BLAST are automated static checkers that took the programming language world by storm. Recently I have spent a bit of time trying to understand the way these tools work and quite honestly, I think it is their ability to formalize their ideas that have made them such successes over as opposed to the ingenuity which we ideally want to promote as good samaritans.

Model Checking in Software systems and Programming Languages

Most of this article may seem like I am stating the obvious (offcourse unlike the rest of my blog!). I have been attending a course on Programming Languages by Prof Wesley Weimer. Been quite awesome till date. We were speaking about static analysis of programming languages and the success of Microsoft’s SLAM project Read More »

Evolution’s Delusive Backdoor Programming in our brains

I recently read V.S.Ramachandran’s Phantoms in the Brain. It is quite brilliant. I would really recommend it to anyone who prides himself of being a rationalist. Read More »

A rationalist’s views on Functional-Programming

The greatest apparent threat that causes us to program functionally is the fact that Object Oriented Programming has failed to address mutability in states that results because of most objective implementations. Read More »

Writing cohesive event driven code in Ruby

For those of you who have played around with some bleeding edge asynchronous HTTP servers like python’s tornado and Ruby’s goliath, I am sure there have been several ahaaaa! moments finding out  things that need improvement. As part of these things, I find that structuring evented code and taking a bottom up approach to debugging nested calls can really dissuade you from asynchronous http approaches itself. Read More »

Interactive Jabber Bots

Vinkesh and I made a presentation at xonf Bangalore on building jabber chat bots in cases where web application seem like a redundant solution. Read More »

Pushing Concurrency out of your System

I am currently working on a project in ThoughtWorks that required a lot of operations work to be done. Translating that to English, we wrote a lot of code that needed to be shared by an online application and a set of background jobs. Not to mentions that a large part of these operations were speaking to REST APIs. Not rocket science right? So  Here is what we did. Read More »

Campus Recruitment

Any expression of sarcasm is just some frustration leaking out amidst what otherwise is ramblings that are rationalized sporadically. There is only one driving reason for most students to join PSG College of Technology. Job offerings! Fair enough if you ask me. Read More »
