obsessing about bdb, queues

So my nightmares do no cease to end, still debating queue solutions and databases. After spending a lot of time thinking about how to handle 100 million entries , concurrency and a lot of jazz here are some conclusions that I have reached.

  • Tokyo Tyrant needs some testing personally. Can it work well within a constrained VPS ? I doubt that after reading all the test results. So need to do a benchmark for this.
  • Tornado , the friendfeed (facebook) non-blocking server looks cool. The primary issues are the lack of an plugin architecture much like django or rails, guess that is something i can give back to them (if and when i start working on it).
  • Python set lookups are blazing fast, in a benchmark today it beat lists lookup (800000 entries) by 10 times

Feeling much better after the flu, I hope to write more often so that the ether (ie the internet) can crawl and archive my existence ;) .

bangalore, h1n1 and queues

So for that last one week a major area of work has been queues and here are the various queues that i encountered

  • memqueuedb - a speedy message queue based upon the memcached client protocol. The idea was to use it to cache certain objects in a system.
  • JMS – Seems to be an integral part of my J2EE learning, this is what often defines performance in an application. Especially when good high speed JMS library implementation cost big money.
  • Airport taxi queue – Now you get in line to get a coupon for a taxi (10 people ahead of you) and then you get on a line with 40 people ahead of you all waiting for taxis at My capital city airport. Awesome. (Did I just see a newspaper whack me on the head :P )
  • Python queue(or Queue) - The real star :) , it actually is well synchronised with locking and all. Quite a rock star data structure he he, must use one of these days for something.

That was the end of the queue rant. Forgiveness for having to bear that. Next on line is Bangalore, I regret carrying a camera as it is super picturesque. Though once i landed the really really dusty air got to me. So by day 2, I ended up with a fever. Sorry to Pallav, and the rest of my friends whom i could not catch up with.

Any how, the point is the first question I asked myself do I have H1n1 (aka swine flu). To make sure i did not, i have taken the pains to outline a checklist for symptoms for the same.

  1. fever
  2. cough
  3. sore throat
  4. body aches
  5. headache
  6. chills
  7. fatigue

Now I did not have 4,5,6 and 7, but just for precaution am going to the doctor and getting myself tested. The only way to stop this from becoming the “plague” of our generation, is that we all consciously take precautions (especially when you can afford to, which I believe most of my readers can).

It is 100% treatable (well, that is what they say) when diagonosis is early. Tamiflu is also going to be available at drug stores. Take care everyone.
