Dropbox: Case study for NOT using Python
Posted by Prashant Deva on July 31, 2013
Interesting post over at the High Scalability blog about Dropbox’s stack.
Everything about it points towards not using python:
1. Needed to mix C with python
2. Had to write custom memory allocator
3. C for inner loops
None of that sounds like something that leads to ‘fast iteration’ (as is implied in the original post).
My IDE doesnt use enough memory
Posted by Prashant Deva on June 29, 2013
I have a powerful PC.
You see, I paid for those 24 gigs of ram. I don’t want them to go unused.
Yet, my IDE takes up less than a gig.
I want it to take more memory. I am fine with memory hogs. If using more memory means that i can get better features or faster release of products, go ahead take more ram. Ram is cheap.
I want every singly byte of that ram to be filled up.

Java’s insane new versioning scheme
Posted by Prashant Deva on May 9, 2013
From the announcement:
The next Limited Update for JDK 7 will be numbered 7u40, and the next 3 CPUs after that will be numbered 7u45, 7u51, and 7u55. The next release will be a Limited Update 7u60, followed by CPUs 7u65, 7u71, and 7u75.
Using digits of PI would be easier to follow…
Chronon 3.8 – Introducing the Global Filter
Posted by Prashant Deva on
With today’s release we are adding another major feature that will make debugging much simpler with Chronon.
A lot of times, the amount of data that Chronon shows you in all the views can be overwhelming. While we do have an extensive filter panel in the Method History view, we wanted to provide a simpler, faster way to filter data across all the views. This makes it easier for you to narrow down to the root cause of the issue.
Introducing the ‘Global Event Filter’.
The UI is integrated in the Timeline View. When you create or edit a filter, it is applied to all the views in the Chronon Debugger instantly!
Here is a video demonstrating the Global Event Filter.
