Did some reading on ip and natting

Yesterday I read quite a lot about natting and ip. It seems what I am trying to do has already been implemented primitively . The rfc nos. 2694 DNSALG and 2663 twice nat are two informative issues.

awesomeness.

Thesis work

shit I need to do a lot of stuff ,and that too in a short time.

The planet lab machines have not arrived as of yet.

I think the basic ip aliasing thing is over. However I am not sure how it should work out in case of public ips because public ips are limited.

I need to understand natting in order to get the bigger picture.

The overall structure of the internet can be summarized as leaf network --isp1 --isp2--- ispn.

and finally at the top there will be one network interconnectiong several others...

as such internet could be represented as a tree-ish hirerchical structure.


Well moving on...

Job interviews conflicting with thesis meetings

Dammit, I am sick of thesis meeting poping out of nowhere and disturbing everything.

The internet and web series

I figure one of the best ways to gloss at current scene is to start at the internet level and then span out to whats going on currently. This will be a brief explanation,and would answer questions that I wasnt able to get during my course time.

Starting with IP, I will go on with what I see best as next part or extension of IP and so on....

Stay tuned, good bye!

The path to manipulate data....

One my way to work with twitter data and their annotation, it seems I will have to know quite a bit of atleast some technologies that are used to serialize data, the earlier man used JSON, so I have to peek into JSON stuff in order to get a hang of it.

JSON , is Java Script Object Notation, much like XML its used to seralize objects, in my case he has used it to parse the csv seperated data, in order to generate objects that can be rather decently accessed.

One good advantage of JSON over XML is that JSON is very light weight, in that you essentially avoid the tagging process that goes on with XML, so var v={ "name":"Nikhil","game":["khokho","dharma-guru"] } and var obj=eval(v), instantly creates an object that you can access with member-of "." operator, obj.name would then return my name.

Working on Named entity recognizers.

Today onwards I will be working on a named entity recognizer. Its supposed to be stanford ner s/w project trained with twitter data. The twitter data was annotated using mturk and other crowd sourcing entities.Now this annotated data is going to go into the NER system and finally this will give us a NER that recognizes the system names.
This is the goal of the project.

End of Spring!

It all ended on 18th may, my pen and my brain smoked, as I left the classroom and went towards the exit. The last of the exams , called Algorithmic analysis (advanced) finished at exactly 2.30 pm, on that day.

Finally, it was all over!

I did some pretty cool things this semester, the coolest of all was a particle simulator...It was a simple 3 dimensional particle simulator, which simulated the gravitational force. The better thing being it worked using open-mp a new technology that allows multi-threading stuff to be done in some 2-3 stmts.

There are some pretty good tutorials out there, which anyone can use, but their isnt much help on the 3 dimensional collision part. So I think I should write a bit about it, and I will in my next post.


So basically, the program follows the Single process multiple data model , and does a spatial decomposition, of the cube in which the actual collision takes place.

A 3d puzzle game could easily be done here...or so I think.

Here are a few screen shots, and a video (the video is quick ,cause There is apparently some shitty problem when recording videos of off linux)
