Eternidade da Existência


Eternidade da Existência
 
Nada poder-se-á apagar a existência pois esta é eterna assim como as ideias e ações cultivadas ao longo dos anos permanecerão vivas em toda imensidão do universo e na sabedoria e harmonia da Mãe Terra, Gaia, sua essência permanecerá pois o corpo pode morrer e ferir-se mas nunca a essência deixará de existir e tão pouco a existência será apagada. Se boas ideias e ações são cultivadas, através de laços e do tempo, com a sabedoria, elas permearão e contribuirão positivamente à sua existência e de outrem.

 Wandeson Ricardo da Silva




Em tributo à todos que adentraram ao plano espiritual.




Que a luz da imensa sabedoria, e a paz que conosco esteje, guie-nos todos pela enternidade da existência.

Novos Paradigmas e o Desenvolvimento Humano - Da Economia Solidária à Economia Baseada em Recursos


Novos Paradigmas e o Desenvolvimento Humano - Da Economia Solidária à Economia Baseada em Recursos

Wandeson Ricardo da Silva - 2012





Nos últimos anos têm-se assistido a explosão de diversas crises financeiras as quais demonstram a total ineficácia e vulnerabilidade do atual sistema econômico. Vemos crescente aumento das desigualdades sociais e um aumento nos conflitos humanos em diversos locais. Tal sistema criou um ambiente não propicio ao desenvolvimento de forma igual e acessível a todos. Neste contexto mudanças fazem-se necessárias afim de corrigir determinados problemas presentes na nossa sociedade atualmente. Podemos pensar neste aspecto em medidas a curto, médio e longo prazo. Que teriam por objetivo resolver tais problemas, além de desenvolver um novo modelo econômico e criar um ambiente propicio à transição para este modelo.

Emergindo


        Assim como a superfície de um oceano penso que devemos manter a superfície de nossa mente limpas para daí permitirmos a iluminação de nossa mente podendo assim emergirmos e contemplarmos a imensidão do que nos cerca, mantendo-nos livres das superficialidades e objetos geradores do sofrimento humano (a ganância, o egoismo, a inveja, a obsessão pelo poder, o preconceito entre outros). Tendo emergido e libertado nos de preconceitos e limitadores de nosso desenvolvimento, de modo geral, podemos assim obter uma maior compreensão sobre nós mesmos e o universo no qual nos inserimos, sendo isso independente de crença ou religião que se siga.

        Limpando e libertando nossa mente, através de uma profunda meditação afim de limpar o 'lixo' (entendendo por lixo todas as superficialidades, preconceitos, e objetos geradores de sofrimento) que concentram-se na superfície de nossa mente, poder-se-á refletir sobre nós mesmos (nossas ações, pensamentos, comportamentos) e sobre nossa sociedade, objetivando superarmos uma visão centrada no 'eu' e colaborarmos ao nosso desenvolvimento e o da sociedade de um modo geral.

“Devemos manter a nossa mente assim como a superfície de um oceano limpas para permitirmos a iluminação podendo assim emergirmos e contemplarmos a imensidão do que nos cerca, mantendo-nos livres das superficialidades e dos objetos geradores do sofrimento humano.”
        
        A partir desta reflexão poder-se-á detectar e compreender um pouco mais sobre os fatores limitadores de nosso desenvolvimento e de nossa sociedade. Penso que a partir disto pode-se obter as respostas, senão parte delas, sobre os questionamentos que nos fazemos e sobre os que levantamos sobre nossa sociedade – uma sociedade sempre centrada na ganância, no egoísmo e no poder – e seus problemas.

Introduction to Computing Explorations in Language, Logic, and Machines - Free Online Computing book

Introduction to Computing Explorations in Language, Logic, and Machines

Free ebook online about computing and theory.

"Computer science is the study of information processes. Computer scientists study how to describe, predict properties of, and efficiently implement information processes. This book introduces the most important ideas in computing. It focuses on how to describe information processes by defining procedures, how to analyze the costs required to carry out a procedure, and the fundamental limits of what can and cannot be computed mechanically."

Music, Sound and Programming

      There is good free tools and libraries for creation and processing of sound  and music for Linux system. With this tools is possible create and generate  sounds. For example the application CSound.

List of tools/libraries and webpages:

CSound
        "Csound is a sound design, audio synthesis, and signal processing system, providing facilities for music composition and performance on all major operating systems and platforms. Its use is not restricted to any style of music, having been employed for many years in the creation of classical, pop, techno, ambient, experimental, and (of course) computer music, as well as music for film and television."
http://en.wikipedia.org/wiki/Csound
 
RoseGarden
      "Rosegarden is a well-rounded audio and MIDI sequencer, score editor, and general-purpose music composition and editing environment."


PythonInMusic 
      Create, processing, generate sound with Python language. Music softwares using Python language programming.

Timidity
      Play midi files and export files for other formats.
"TiMidity++ is a software synthesizer. It can play MIDI files by converting them into PCM waveform data; give it a MIDI data along with digital instrument data files, then it synthesizes them in real-time, and plays. It can not only play sounds, but also can save the generated waveforms into hard disks as various audio file formats."

LilyPond 
      Tool for edit partiture. "LilyPond is a music engraving program, devoted to producing the highest-quality sheet music possible. It brings the aesthetics of traditionally engraved music to computer printouts."

TuxGuitar
 "With TuxGuitar, you will be able to compose music using the following features
  • Tablature editor
  • Score Viewer
  • Multitrack display
  • Autoscroll while playing
  • Note duration management
  • Various effects (bend, slide, vibrato, hammer-on/pull-off)
  • Support for triplets (5,6,7,9,10,11,12)
  • Repeat open and close
  • Time signature management
  • Tempo management
  • Imports and exports gp3,gp4 and gp5 file"



ABjad
      "Abjad helps composers build up complex pieces of music notation in an iterative and incremental way. Use Abjad to create a symbolic representation of all the notes, rests, staves, tuplets, beams and slurs in any score. Because Abjad extends the Python programming language, you can use Abjad to make systematic changes to your music as you work. And because Abjad wraps the powerful LilyPond music notation package, you can use Abjad to control the typographic details of the symbols on the page."

PySynth
      "PySynth is a simple music synthesizer written in Python.  The goal is not to produce many different sounds, but to have scripts that can turn ABC notation into a WAV file without too much tinkering."


Download song Enya in midi format like example/demo (unknow author for midi, song by Enya) below:
Enya - Boadicea (midi file)

(If you know other free software and libraries for processing, edit/create and generate sounds and music tell us, post your comment.)

Ebook: Signal Processing

Signal processing is a field of applied mathematics that study the operations and analysis of signals.

Introduction

    The signal is a function that represent a physical quantity or a variable containing information of a phenomenon. Mathematically, a signal is represented as a function in a independent variable t (time) and express like by X(t). The signal can be continuous or discrete.

Example:(signal pulse). Let a > 0, the signal of pulse p a ( t )   unidimentional is a signal of constant intensity and finite duration. This signal is represented by the function:
    
p a ( t ) = if   t     a ; 0 if t < a ; p_{a}(t) = left lbrace binom{1 ~ if ~ abs{t} ~ >= ~ a;}{0 ~ if ~ abs{t} ~ < ~ a; } right rbrace


Below twoo link for ebooks about Signal Processing.
(Abaixo dois links para ebook sobre processamento de sinais.)

2. DSP Guide(Digital Signal Processing). (http://www.dspguide.com)
