I recently used mongoDB for a project and I am quite impressed with its speed and MongoDb is a popular no-sql database .For huge data Google uses its own database structure i.e Big table mongo db has too many pros over MySQL but also cons.It all depends on what your pupose would be.MongoDb is definitely not a RDBMS hence in a case where you would be using too many joins to get your data from different tables you need a sql database . In a project where you have huge number of records and constants writes and reads mongoDb would be a write option for you.
In mongoDB collection is similar to the tables in collection and collection would contain several documents which is a BSON document values are stored corresponding to a key and key may vary from every document in a collection this makes it flexible for varying type of data. If your DB is 3NF and you don’t do any joins (you’re just selecting a bunch of tables and putting all the objects together, AKA what most people do in a web app), MongoDB would probably kick ass for you. But If I need ACIDity, I won’t use NoSQL.
Tornado is a Python web framework and asynchronous networking library, originally developed at FriendFeed. By using non-blocking network I/O, Tornado can scale to tens of thousands of open connections, making it ideal for long polling, WebSockets, and other applications that require a long-lived connection to each user.
whenever u need to pass on to hundreds of clients at once no need to get request this follows a push mechanism,and as it is built on python is pretty fast too.Check it out on developers.facebook. com /opensource
After my friend convincing me for the course I did the yes+ but after experiencing the course myself i felt i really wanted something like this long ago …. wanna know what’s YES+ is all about
Everyone understands their enlightened side differently. For one person it’s the side that can take a final without stress, for someone else it’s about re-connecting with a level of freedom experienced only as a kid, and for a third person it means taking responsibility for the world around them. When we are in touch with our enlightened side we are happy, we are in the moment, and we naturally want to help others get there too. This is the basis of yesplus.
yesplus workshops help you live in your enlightened side
Temporary happiness is easy, we can get that through a number of experiences, people, and even substances. But how do we stay in that place, how do we build on it, and achieve sustainable happiness? That is where the yesplus workshop comes in.
yesplus projects are a natural expression of living with sustainable happiness
When you feel better, you feel more connected to the world around you. When you become more aware, you see what is going on and want to do your part. Graduates of the workshop take responsibility for fixing some big problems happening right now in the world, and you can do the same.
Well reading this wont help u at all come and experience it yourself an know it!

The Android 4.1 Jelly Bean update is being highly anticipated by thousands of smartphone owners across the worl, with the expectation that it will see a number of vast improvements in the Android-smartphone interface.
Here are some of the features and improvements users can expect.
Fans can expect the interface on the Jelly Bean to be greatly improved. It has combined the best of some of the company’s previous builds in the Android 4.0 Ice Cream Sandwich and the tablet-exclusive Android 3.0 Honeycomb.
The upgraded interface provides users with a higher quality interface and an overall better and smoother experience than ever before on the Android operating system.
It has been confirmed that a sharp blue menu is offered on a black background, with the menus featuring white text and a pretty nice font that catches the eye instantly. Other improvements can bee seen in the homepage, wallpapers and icons among numerous other nice touches.
The interface is bright and is definitely a good experience visually. Users of the Jelly Bean will immediately be able to tell this is a well developed product that is bringing together many things that have been learned through years of experience in previous versions.
Importantly, the Jelly Bean’s performance is also fantastic, with Google now adding a Project Butter feature with the firmware. Project Butter is the major new innovation in Android 4.1 Jelly Bean, and focuses on making the entire UI “fast, fluid and smooth.”
Impressive triple buffering in the graphics pipeline is included, which ensures consistent frame rates with interface animations.
Quad core chipsets are also supported by Jelly Bean leading numerous experts to boast that Jelly Bean now performs as well as both iOS and Windows Phone, which were both previously heralded as better optimized.
j2ee vs .net
Though the debate over the superiority of .Net versus that of Java 2 Platform, Enterprise Edition (J2EE) seems a hot topic in today’s technology circles, many people believe it is simply a marketing battle of little consequence. Marketing battle or not, the debate’s effects will one day prove critical in software evolution. Thus, Sun Microsystems’ and Microsoft’s executive teams have committed significant marketing budgets in an effort to gain advantage. Should Microsoft lose this battle, the operating system might simply become a lifestyle choice. Sun’s victory could one day enable software to run on any operating system, causing Microsoft’s dominance in operating systems to slowly fade as other operating systems, capable of running the same software, come to market. On the other hand, should Microsoft succeed, it will further entrench its technology suite as the de facto standard for the foreseeable future. In this article, we compare the J2EE and .Net technologies to help you decide which one is worth the investment.
