MongoDB: The pioneer of NoSQL....Easy and really quick to learn..

I just signed up for 10gen free class on MongoDB...and wow..its so easy and interesting to follow.
I wondered what was all this buzz about NoSQL...but seeing it and coding it on my own has really made me believe that it is going to grow larger and more effective over the years to come.
One thing that sets this new trend apart from others is its ability integrate easily with the client code: It can be just accessed from the code using the OOP approach that we are all accustomed to( I mean if you had been programming!)..

Its schemaless ..meaning it does away with all those CRUD statements that we all use for RDBMS..though it has an adequate means of addressing all of that through a simple syntax and various APIs it provide for the same. One thing that it is critical about is the lack of:
>Transactions
>and Joins
Still it has enough for all the uses it is meant for..where you would really have to do a big maintenance of bank accounts spanning over many countries...say in a web app or say a large database oriented projects involving many entries having the need for dynamic updates: it can do and I would say it can fairly do all that in a neat and nice little piece of code.

A nice feature I am impressed is the ability to hold entries of multiple and inconsistent columns in one collection..that would be impossible in RDBMS .
Thumbs up to the team Mongo and all those maintaining the class.

How to create a bootable USB pendrive in Linux

If it was windows, it would be much easier ...for we have the universal USB installer. In Linux, we can't use that: however, we need not worry, guys have done a great job by creating a much easier tool to do the work. The tool is called gparted. It is a nice GUI tool to do our work. So lets see how we shall do it. >Open the terminal . >Now type: sudo apt-get install gparted ......This will install the tool ...well and good if you had it from before. >Now type: sudo apt-get install-3g ( gparted installed this as default for me...just see if it did for you). >Now open the tool via: System>Administration>Gparted Partition Tool >Now you are almost done....Click the File and choose the drive for the particular USB. >Right click on the drive when it is enlisted. See Manage Flag menu and click to enable boot. >Now go to Partition menu at the top panel and format the drive as ntfs . This will keep the work as pending operation ...click the cor...

Behind the Scenes: How Generative AI Creates Music, Art, and Stories

When Machines Dream We’re living in a world where machines don’t just compute—they create. Generative AI is writing novels, composing symphonies, and painting pictures. But what’s really going on behind the screen? This post pulls back the curtain to reveal how generative AI actually creates —from writing a bedtime story to composing a lo-fi beat. Whether you're a curious creator or tech enthusiast, you’ll see the art of AI through a new lens. What is Generative AI, Really? Generative AI uses machine learning models—especially neural networks—to generate new content based on learned patterns. Trained on vast datasets, these models produce original music, images, and text based on user prompts. 1. How AI Writes Stories (e.g., ChatGPT, Claude) Step-by-step: You give a prompt: “Write a story about a lonely robot who finds a friend in the forest.” The model (like ChatGPT) draws on its training data to predict and generate the most likely next word, sentence, or paragr...

How to find the difference between two files from windows shell

Well I was just wondering how could I see the difference between two files in windows. Searching the net, I saw some softwares  that would do the job for me..But I wanted simple and fast not so sophisticated ... I found out we could do using a simple tool...fc..from the DOS prompt. FC is a command to view the difference of two files or set of files.. So the steps are: 1> go the directory where the files are.. 2>type  fc first-filename second-filename ....and there you go..You will get the result each different section divided by line of stars.. ...Its simple ...right?? I love it....The following explains the full usage method ------------------------------------------------------------------------------------------- Syntax: FC [d:][path]filename [d:][path]filename [/A][/C][/L][/Lb n] [/N][/T][/W][/(number)] for binary comparisons FC [d:][path]filename [d:][path]filename [/B][/number]  FC reports differences between the two files you specify. FC firs...
