Node Samples

I added a Picasa API search demo application


I added more basic functionality to my JavaScript scraper:

Now, each document element has a list of attributes. As a concrete use case, there are two console samples that generate structured JSON data from two  popular Argentinean news sites:


An interpreter of Go programming language written in C#, work in progress

Some lexer pieces in place, and the first parse expression method.


Artificial Neurons in JavaScript:

I removed events: no use case for them, yet. I added the construction of a multilayer network. Next step: automatic learning using back-propagation.


Clojure interpreter in C#:

I implemented metadata reader. Big surgical refactor: now adding metadata produces a new object (in previous naive implementation, the metadata was attached to the original object). Now, it follows Clojure expected semantics. But TDD saved my day!

Google Code Jam

I participated in Round 1B:

I solved only one problem, check

For another problem, Lottery, I had a not written solution with O(n,m). I thought that it was not good enough for processing large dataset. But, apparently, the large dataset had no hard problem. Some contestants solved the problem using O(n,m) solutions. It was an interesting problem, that deserve more thought. I didn’t understand the third problem (I confused tickets with flights)


There is a new empty Laravel PHP sample at Some new node parse methods in ScalaSharp I added first map, reduce implementations to I added more features to serialization in

I worked on three non-public projects, too.

More fun is coming.

Keep tuned!

  3. When someone writes an piece of writing he/she retains the thought
    of a user in his/her mind that how a user can understand it.
    Thus that’s why this paragraph is perfect. Thanks!

  4. Nice blog! Is your theme custom made or did you download itt from somewhere?
    A design like yours with a few simple adjustements would really
    make my blog jump out. Please let me know where you
    got your theme. Kudos
