-## Branching hypothesis
-
-* Diferenciação aplicada à história e à história da ciência.
-* É um processo de criaçãode ramos que lida com excessões.
-
-### Hipótese 1
-
-Qualquer conjunto de ideias e teorias pode ser organizado
-numa árvore lógica.
-
-A forquilha indica a cisão; o nível acima, ou metanível, representa uma
-categoria unificadora. Assim, mesmo a contradição se encaixa.
-
-### Hipótese 2
-
-Neste esquema, fatos são definidos como **trechos** de caminhos:
-um mesmo fato percorre regiões da árvore, podendo simultaneamente andar por
-diversos ramos.
-
-Fatos são observações do real mapeado em ideias que não necessariamente
-representam o real e que não necessariamente simulam o real com acurácia.
-
-Fatos são tão relativos quanto ideias.
-
-Um entendimento do real é a árvore junto com um caminho percorrido.
-De modo que se torna possível a seleção de concepções de mundo.
-
-### Hipótese 3
-
-Qualquer conjunto de ideias pode ser racionalizado, isto é,
-descrito/justificado por um sistema de regras, por mais estaparfúrdio
-que seja.

-## Learning Python
-
-### Which version to start? 2.x or 3.x?
-
-Short answer: start learning 3.x and, if needed, check the differences with 2.x.
-
-From [Should I use Python 2 or Python 3 for my development activity?](Should I use Python 2 or Python 3 for my development activity?):
-
- Besides, several aspects of the core language (such as print and exec being
- statements, integers using floor division) have been adjusted to be easier for
- newcomers to learn and to be more consistent with the rest of the language, and
- old cruft has been removed (for example, all classes are now new-style,
- "range()" returns a memory efficient iterable, not a list as in 2.x).
-
- [...]
-
- In particular, instructors introducing Python to new programmers should
- consider teaching Python 3 first and then introducing the differences in Python
- 2 afterwards (if necessary), since Python 3 eliminates many quirks that can
- unnecessarily trip up beginning programmers trying to learn Python 2.
-
-Also:
-
-* [Python Future: Easy, clean, reliable Python 2/3 compatibility](http://python-future.org/).
-* [Should I learn Python 2 or 3?](https://www.dataquest.io/blog/python-2-or-3/).
-
-### General
-
-* Everything is an object. Really? What about symbols like + - and =?
-* The `dir()` and `help()` functions are really useful.
-* Great idea: iteration protocol.
-* There are sequences and sum operations common for all types and specific type operations.
-
-### Iteration and optimization
-
- In general, leading and trailing double underscores is the naming pattern
- Python uses for implementation details. The names without the underscores in
- this list are the callable methods on string objects.
-
-### Polymorphism
-
-Python encourages polymorphism:
-
- This is related to the idea of polymorphism mentioned earlier, and it stems
- from Python’s lack of type declarations. As you’ll learn, in Python, we code to
- object interfaces (operations supported), not to types. That is, we care what
- an object does, not what it is. Not caring about specific types means that code
- is automatically applicable to many of them—any object with a compatible
- interface will work, regardless of its specific type. Although type checking is
- supported—and even required in some rare cases—you’ll see that it’s not usually
- the “Pythonic” way of thinking. In fact, you’ll find that polymorphism is
- probably the key idea behind using Python well.
-
-### Numeric Display Formats
-
-* [14. Floating Point Arithmetic: Issues and Limitations — Python 2.7.13 documentation](https://docs.python.org/2/tutorial/floatingpoint.html)
-* [What Every Computer Scientist Should Know About Floating-Point Arithmetic](https://docs.oracle.com/cd/E19957-01/806-3568/ncg_goldberg.html)
-* [Floating-point arithmetic - Wikipedia](https://en.wikipedia.org/wiki/Floating-point_arithmetic).
-
- This floating-point limitation is especially apparent for values that cannot be
- represented accurately given their limited number of bits in memory.
-
- [...]
-
- fractions and decimals both allow more intuitive and accurate results than
- floating points sometimes can, in different ways—by using rational
- representation and by limiting precision
-
-### Types
-
- More formally, there are three major type (and operation) categories in Python
- that have this generic nature:
-
- Numbers (integer, floating-point, decimal, fraction, others)
- Support addition, multiplication, etc.
-
- Sequences (strings, lists, tuples)
- Support indexing, slicing, concatenation, etc.
-
- Mappings (dictionaries)
- Support indexing by key, etc.
-
- [...]
-
- The major core types in Python break down as follows:
-
- Immutables (numbers, strings, tuples, frozensets)
- None of the object types in the immutable category support in-place changes,
- though we can always run expressions to make new objects and assign their
- results to variables as needed.
-
- Mutables (lists, dictionaries, sets, bytearray)
- Conversely, the mutable types can always be changed in place with operations
- that do not create new objects. Although such objects can be copied, in-place
- changes support direct modification.
-
-So remember that when [copying](https://stackoverflow.com/questions/2612802/how-to-clone-or-copy-a-list#2612815)
-or referencing a list.
-
-Also, [take care with handling mutables as arguments and as default arguments](http://www.thedigitalcatonline.com/blog/2015/02/11/default-arguments-in-python/),
-also explained [here](https://docs.python.org/3/tutorial/controlflow.html#default-argument-values) and [here](https://docs.python-guide.org/writing/gotchas/)
-(common gotchas).
-
-From [Scopes an Namespaces](https://docs.python.org/3/tutorial/classes.html#python-scopes-and-namespaces), telling that assignments bind names to objects:
-
- A special quirk of Python is that – if no global statement is in effect –
- assignments to names always go into the innermost scope. Assignments do not
- copy data — they just bind names to objects. The same is true for deletions:
- the statement del x removes the binding of x from the namespace referenced by
- the local scope. In fact, all operations that introduce new names use the local
- scope: in particular, import statements and function definitions bind the
- module or function name in the local scope.
-
- The global statement can be used to indicate that particular variables live in
- the global scope and should be rebound there; the nonlocal statement indicates
- that particular variables live in an enclosing scope and should be rebound
- there.
-
- [...]
-
- Actually, you may have guessed the answer: the special thing about methods is
- that the instance object is passed as the first argument of the function. In
- our example, the call x.f() is exactly equivalent to MyClass.f(x). In general,
- calling a method with a list of n arguments is equivalent to calling the
- corresponding function with an argument list that is created by inserting the
- method’s instance object before the first argument.
-
-Week references (from [here](https://docs.python.org/3/tutorial/stdlib2.html):
-
- Python does automatic memory management (reference counting for most objects
- and garbage collection to eliminate cycles). The memory is freed shortly after
- the last reference to it has been eliminated.
-
-Now explain this:
-
- Python 2.7.13 (default, Sep 26 2018, 18:42:22)
- [GCC 6.3.0 20170516] on linux2
- Type "help", "copyright", "credits" or "license" for more information.
- >>> hex(id([]))
- '0x7f6264bbf368'
- >>> hex(id([]))
- '0x7f6264bbf368'
- >>> x = []
- >>> hex(id(x))
- '0x7f6264bbf368' # both x and [] points to the same memory location
- >>> x.append('0')
- >>> hex(id(x))
- '0x7f6264bbf368' # x still points to the same memory location
- >>> hex(id([]))
- '0x7f6264baeab8' # now [] points somewhere else
- >>> hex(id('test'))
- '0x7f6264bc9480'
- >>> x = 'test'
- >>> hex(id(x))
- '0x7f6264bc9450'
- >>> hex(id('test'))
- '0x7f6264bc9450'
- >>> hex(id('another test'))
- '0x7f6264bcc1f0'
- >>> x = 'another test'

-### Threads
-
-From [GlobalInterpreterLock](https://wiki.python.org/moin/GlobalInterpreterLock):
-
- In CPython, the global interpreter lock, or GIL, is a mutex that protects
- access to Python objects, preventing multiple threads from executing Python
- bytecodes at once. This lock is necessary mainly because CPython's memory
- management is not thread-safe. (However, since the GIL exists, other features
- have grown to depend on the guarantees that it enforces.)
-
- [...]
-
- The GIL is controversial because it prevents multithreaded CPython programs
- from taking full advantage of multiprocessor systems in certain situations.
- Note that potentially blocking or long-running operations, such as I/O, image
- processing, and NumPy number crunching, happen outside the GIL. Therefore it is
- only in multithreaded programs that spend a lot of time inside the GIL,
- interpreting CPython bytecode, that the GIL becomes a bottleneck.
-
-From: [Thread State and the Global Interpreter Lock](https://docs.python.org/3/c-api/init.html#thread-state-and-the-global-interpreter-lock):
-
- When threads are created using the dedicated Python APIs (such as the threading
- module), a thread state is automatically associated to them and the code showed
- above is therefore correct. However, when threads are created from C (for
- example by a third-party library with its own thread management), they don’t
- hold the GIL, nor is there a thread state structure for them.
