NOOBS software

Hi Amando.

Noobs is the pack which has some linux versions such as rasbian or openElec, so when you dropping the NOOBS into the SDCARD, as soon as you boot the PI, you will be required to select the version of linux more likely by you.
making one example >> noobs is like a bag full of cans and each can is one OS

for your second question i got the answer from QUORA which fits for your question very well.

Python and C++ are extremely different languages, and most of the differences aren't strictly advantageous in one direction or the other. That said, for most uses, it's easy to pick a side and make a good argument for or against particular language and implementation features.

Speaking of which, I'll note which features are primarily those of the language versus those of the commonly used implementations: it's possible, for example, to use a C++ interpreter as your primary environment, but It Just Isn't Done.

So, without further ado, roughly in my personal order of importance, here are some foundational differences.

• Memory management: C++ doesn't have garbage collection, and encourages use of raw pointers to manage and access memory. It differentiates between heap and stack, and it requires you to attend to values versus references. C++ requires much more attention to bookkeeping and storage details, and while it allows you very fine control, it's often just not necessary.
• Types: C++ types are explicitly declared, bound to names, checked at compile time, and strict until they're not. Python's types are bound to values, checked at run time, and are not so easily subverted. Python's types are also an order of magnitude simpler. The safety and the simplicity and the lack of declarations help a lot of people move faster. Speaking of...
• Language complexity: C++ is a beast of a language. The spec is 775 pages of language legalese, and even the best C++ developers I've known can be caught up short by unintended consequences in complex (or not so complex) code. Python is much simpler, which leads to faster development and less mental overhead.
• Interpreted vs compiled (implementation): C++ is almost always explicitly compiled. Python is not (generally). It's common practice to develop in the interpreter in Python, which is great for rapid testing and exploration. C++ developers almost never do this, gdb notwithstanding.

And these differences, in turn, stem from a general difference in philosophy:

C++ tries to give you every language feature under the sun (circa 1990, at least) while at the same time never (forcibly) abstracting anything away that could potentially affect performance.

Python tries to give you only one or a few ways to do things, and those ways are designed to be simple, even at the cost of some language power or running efficiency.

In many cases, Python's philosophy is an advantage because it lets you get most tasks done more easily and more quickly with less mental overhead.

Of course, they also share many similarities: they're both strongly at home in the OO paradigm; they both have a generally imperative feel with some not-entirely-comfortable functional features; they both have exceptions; they both have minimal, library-based concurrency support.

None of this touches on differences in how they're used in practice, or specific differences in syntax or language mechanisms, but if you're interested in the ground-up advantages, I think this is a good place to start.

Ah i see. thank you so much for the clarification. which OS do you use and why (assuming you have a raspi)? I see a lot of people using Raspbian, would like to know pros and cons to the others.

Sincerely

Amando
