After months of deliberation (and lack of time, motivation….), this week I finally started playing with HTML5. Having read(heard) a lot about HTML5 canvas, I decided to start with it first. And here is the result : An application which demonstrates bubble sort using html5 canvas (line) and some javascript. Canvas part was straightforward, but [...]
Read more →The instagram challenge from few weeks was quite interesting. Even though I missed out on t-shirt, I got an offer for their sticker (which I promptly forgot to reply to !). Here is my solution:
Read more →It has been a long time since I have posted anything here. Since my last post, quite a few things have changed. As my posts here clearly highlight, I mostly use Flex for my visualization works and few weeks back there were some development which pointed at the direction of future web development. Everybody knows [...]
Read more →Flex 4.5 DataGrid seems to be the recurring theme of this blog. Just can’t seem to break out of it. Not with the post like this, which shows how to scroll to specified row/column. Hopefully it will be the last post of this series (unless I find some massive world-changing bug in DataGrid). Anyway, one [...]
Read more →Even though I have been practicing code kata for a while now, this is the first time I am organizing (and documenting) it with Git. So for this momentous occasion, I figured it would be fitting to start the process by using one of the code katas by its neologist Dave Thomas. This kata deals [...]

Read more →Lately, finding distances between sequences of genotypes efficiently has been the theme of my work. I simulate thousands of sequences and calculate the hamming distance for all the pairs. Seems simple and straightforward, right? Well if the number of sequences is 500 then there are 124750 pairs. And if each sequence is of length 500 [...]
Read more →We can easily extend the concept of similarity and distances into the field of molecular biology. Protein or DNA sequences can be compared to other protein or DNA sequence to quantify the similarity between them. This similarity value helps in the identification of the evolutionary distance between them. It also facilitates the prediction of the [...]
Read more →Yesterday, I had to write some codes to merge hundreds of “xlsx” files into one csv file. I wanted to avoid java, because of my experiences with POI and jexcelapi mostly due of the number of lines of codes that I had to write. I looked around for packages in Python (can anybody beat python [...]
Read more →Recently I was reading a wonderful book called “Programming Collective Intelligence” and it got me thinking more about the ubiquity of similarity (especially the topic on recommendation system). The concept of similarity is so ubiquitous yet we somehow let it creep under our observational radar. Its almost similar to breathing – we keep on doing [...]
Read more →Lately I have been working with Parsley framework a lot after a brief hiatus. And it still keeps on pleasantly surprising me with what it has to offer. Parsley messaging framework is one of them. Its simple enough to understand and it provides really clean decoupling (between objects as well as from framework). Decoupling sending [...]
Read more →I tried hard not to add yet another post related to spark datagrid, but this one has been such an annoying experience that I am compelled to share it with anybody who would listen. By now it must be well-known to the flex community that the current version of spark datagrid doesn’t have the lockedColumnCount [...]
