Open Social - social networking APIs

These days i was reading more and more about startups...But the interesting thing is most of the startups are for enabling Web2.0 technologies and applications. One of the main focus is social networking domains, like orkut, facebook, bebo, etc..But the funny thing is the interfaces and features provided by almost all the social networking sites are same(may be lookwise it is different).So, it is very logical to have a common APIs to use by all the application. The search for this APIs gave me this link :

Yes, Open social makes the design of social networks very easy. OpenSocial is a set of common application programming interfaces (APIs) for web-based social network applications, developed by Google along with MySpace and a number of other social networks. It was released November 1, 2007.

A Bash script to download the picasa albums

Google restricts the download of picasa web albums to the users with Picasa software only. Google released their Picasa version for linux - Redhat and Ubuntu sometime back. Today i installed the Picasa2.7 version in ubuntu. It is working fine. But the download feature is not working in picasa web link. I think it is a known issue with Firefox, in linux or some add-ons might be required.

So, i started googling. I ended up in this link -

Thanks for the problem. ..:) This bash script is working very fine in linux. I should say it is faster than download with picasa software. Anyway i started learning more about bash scripting. In my last article, i wrote about scripting using Python - Scripting is very powerful tool for most of the linux users.

Python - a comparison with C

Here you go..:

Here a spelling checker is implemented in Python and C. Python code is just 21 lines and C code is almost 190 lines. But for big dictionaries, C code performance is much better compared to Python version.

Loopt - Mobile social network

Today watched a video about loopt in youtube. I always felt that social networking sites like facebook, orkut are very powerful tools for connecting with people through internet. But this one seems to be even more interesting..

Loopt is a way of connecting with your friends through mobile. Loopt uses GPS and related data to display the location of a user’s friends along with their presence status (available, away, etc) on maps and lists. Users will be able to request alerts when friends are within a certain distance, send messages to groups of friends within a certain distance and soon will be able to tag and blog physical locations in a way that’s accesible to friends through Loopt.

This one is freely available with most of the carriers and devices in North America.
