Enjoy.
Well, we are here to create a tutorial explaining how upgrade nook from firmware 1.4 to 1.5 without problems.
The new firmware have some enhancements that deserve attention, well, not, just the speed to change between pages. This is really the only thing that made me upgrade. About 1 second decreased to almost instantaneous. (search on youtube)
This tutorial will not like the first, I will explain what you whant to do, but without pictures.
The ideia behind it is change your launcher and install the wifi locker, with this you be able to start and stop adb from inside you nook. Let’s go:
1- I believe you have already have nook 1.4 or others with root.
2- We will install a new launcher (Nooklauncher or Mynook.ru_Launcher), in this case, Nooklauncher, then download here
3- Connect with ADB to nook with “adb connect NookIP”
4- Install nooklauncher with “adb install nookLauncher.apk”
5- Download the packages file with “adb pull /data/system/packages.xml packages.xml”
6- Edit the packages.xml with notepad and change after <preferred-packages/> tag adding
<preferred-activities> <item name="com.nookdevs.launcher/.NookLauncher" match="100000" set="2"> <set name="com.bravo.home/.HomeActivity" /> <set name="com.nookdevs.launcher/.NookLauncher" /> <filter> <action name="android.intent.action.MAIN" /> <cat name="android.intent.category.HOME" /> <cat name="android.intent.category.DEFAULT" /> </filter> </item> </preferred-activities>
7- Push the file to nook with “adb push packages.xml /data/system/packages.xml”
8- Install Wifi Locker, download here and install with “adb install nookWifiLocker.apk”
9- Restart your nook, then press and hold an icon, if change the screen showing the icon “+”, all right, your nook is ready to upgrade. Befores upgrade, just try to add the wifi locker to start menu and test if it works
10- We need to fix the Firmware Update Service, you can pull the file FirmwareUpdateService (my file FirmwareUpdateService.apk from firmware 1.4.1) and push with “adb push FirmwareUpdateService.apk /system/app/FirmwareUpdateService.apk”
11- Now update in “my library” and select “Check for new B&N content”, Nook will download and install.
12- Restart again after finish, and disable the automatic updates again. First go to wifi locker and select start/stop adb until show “stop adb”.
13- Connect again with “adb connect NookIP”
14- Backup the firmware update file with adb pull /system/app/FirmwareUpdateService.apk FirmwareUpdateService.apk
15- Remove the firmware update file startind shell with “adb shell” and removing the file with “#rm /system/app/FirmwareUpdateService.apk”
16- Restart the nook and enjoy the new speed.

Hellow everyone, I could update my hacked Nook firmware 1.4 to firmware 1.5 keeping the root.
Tomorrow I will put here how you do this, in english and portuguese.
Tomorrow will be too my final work on university, good day for all.
Resolvi colocar mais coisas em português, deste modo como este assunto é um pouco escasso na internet, está aqui um pouco mais de conteúdo.
Computação Musical Ubíqua – Da Ecocomposição à Música Ubíqua
A partir da apresentação do Dr. Damián Keller
Inicialmente baseando-me no nome da palestra, tentei encontrar alguma informação sobre o que se trata e realmente foi difícil encontrar qualquer coisa que explicasse de forma sucinta e simples o que seria computação musical ubíqua. Inicialmente busquei computação musical, em seguida computação ubíqua e por último, música ubíqua. Computação musical está relacionada à utilização da computação no auxilio ou criação de música. A computação ubíqua consiste em um modo de se criar sistemas que sejam percebidos e utilizados de forma transparente, ou seja, sem que haja necessidade de um esforço por parte do utilizados para aprender ou utilizar de modo diferente do natural qualquer coisa. Por fim, a música ubíqua, a mais difícil de encontrar informações, me pareceu um tanto vaga inicialmente, porém uma definição que me pareceu bem descritiva será um conceito de se fazer música de forma natural e que seja entendido por qualquer pessoa sem necessidade de aprendizado e de diversas fontes.
Como o assunto é muito escasso na internet, rapidamente caí em páginas que apontam o professor Damián Keller, e com isto encontrei referências a ele no Simpósio Brasileiro de Computação Musical de 2009, onde nos anais do evento pude encontrar o artigo intitulado “Ubiquitous Music: Concepts and Metaphors”, contendo informações a respeito do que poderia ser a palestra e melhorando alguns conceitos que foram melhor explicados na apresentação.
Ao iniciar a palestra, o professor começou falando da viajem por todo o percurso do rio Amazonas, coletando material sonoro para a pesquisa. Em seguida chegou a parte dos conceitos onde foi explicado alguns conceitos como ações epistêmicas e ações pragmáticas, onde a primeira consiste no processo de descoberta, planejamento e a criação, e a segunda o processo de realizar as ações criadas e produzir um resultado final. Uma coisa falada no artigo que não havia entendido perfeitamente também foi explicado neste momento, a palavra affordances, que após a explicação pude perceber que é o conjunto de possibilidades interação entre um agente e o ambiente. Foi falado também sobre a framework criada para a criação de música, categorizando as atividades e definindo-as. Houve uma explicação de como é o conceito de arpejo, que inicialmente eu não tinha ideia do que seria, porém pude perceber que é apenas um conjunto de notas sequenciais, além da explicação teórica de como representar a criação musical através do uso de elementos que segundo quatro estágios de desenvolvimento visa criar um sistema musical, que para mim, como um algoritmo, você deve ir estruturando a sequência até resultar num resultado final sequencial. Ainda no mesmo assunto houve a apresentação do software para celulares arpejador e em seguida a explicação e exibição do sistema desenvolvido em Java MOW3S, onde se cria sons arrastando um mouse sobre uma área, e o som gerado é influenciado pela sua posição. Com a explicação de alguns modelos sonoros, que são definidos de modo mais detalhado no artigo, explicando a metáfora de interação instrumental, que consiste em você interagir em um instrumento para gerar som, a metáfora do copo, onde se cria a ideia de que apenas o estar em um local pode-se criar música sem interação direta e gerando-se música a partir de um estado, e por último a ecocomposição, que seria a interação cinética entre um agente e um objeto qualquer, mas também haveria a retroalimentação do próprio objeto com ele mesmo. Ao fim foi falado explicado e exibido o som da exposição “Urban Corridor”, onde utilizando a metáfora da xícara, geravam-se sons diferentes baseando-se na posição das pessoas que passeavam pelo espaço. Ainda foi comentado a respeito do estudo “Uma Noite na UFAC” onde se obteve dados a respeito da relação entre escolaridade e apreciação da música.
A maior parte do artigo assim como a apresentação visa criar bases teóricas para o inicio da criação pesquisas e desenvolvimento de sistemas na área de computação musical ubíqua, já que o mesmo é algo recente de 2005. Muitos novos softwares que permitam por em prática estes conceitos serão criado ainda e acredito que este seja apenas o inicio de uma área que será estudada por muitas outras pessoas e certamente é animador saber que agora que começou e conhecemos o assunto logo o começo, é como uma estreia.
Resumo. Uma tendência vista na maioria das empresas com pesquisas que indicam um crescimento previsto para certa de US$16 bilhões até 2013, o uso de Software as a Service traz consigo diversas alternativas ainda pouco faladas no mundo dos serviços como IaaS e BIaaS. O mundo do “aaS” está se tornando cada vez maior, pois representa uma mudança no pensamento do que é necessário nas empresas.

Introduction to High Availability Database

Abstract. This article discusses concepts of availability IT environments, especially the database, and exemplifies the use of cluster system database high availability of Oracle Real Application Clustesr (RAC), describing its main advantages.
Resumo. Este artigo aborda conceitos de disponibilidade em ambientes de TI, principalmente banco de dados, e exemplifica o uso do sistema de cluster de banco de dados de alta disponibilidade da Oracle Real Application Clustesr (RAC), descrevendo suas principais vantagens.
1. Introduction
With technological advances coming from the twentieth century, the ease of access to information has become very evident, since the Internet now connects most of the computers worldwide. Likewise there is a very large growth in technology, these innovations also bring new problems, it is necessary to provide this access on a scale never seen before.
Just as the need for access to information becomes increasingly important, the possibility of errors occur and their impact increases proportionally becomes increasingly relevant in a technologically advanced setting. Large faults can occur at any time since events such as hurricanes, floods, earthquakes can occur in almost all locations and most recently, attacks like the “September 11″, problems with attacks from hackers and satellites in general can not easily be predicted .
2. Availability and Oracle RAC
Considering the importance of information needs in a business today, if there is a failure of a system, it can take hours or even days to diagnose and deliver the content again, that seen in the possibility of a hardware problem, which can be difficult to discover the reason for the failure in general has been relatively easy to swap parts, but in case of software systems, where a critical failure, it is generally more complicated to find out why and discovered after a time it may take high until a patch can be obtained. This type of problem occurs when you can also generate a vicious cycle of accusations where the hardware vendor can blame the software vendor and vice versa, if not explicitly discover the cause of failure.
One possibility for avoiding these types of problems is to use redundancy as a way to ensure constant availability of both hardware and software / data, thus reducing the points where there may be problems, so-called single points of failure (SPOFs). When a fault occurs, should be carried out migration of services from one server to another problematic assets, this transition is called failover. In the case of a failover, the ideal is to be as transparent as possible, not exceeding five minutes so you can ensure that applications can more easily get around this problem, and require the least manual intervention possible and guarantee continued access to data, the latter characterized by the backup of the information. When a failover happens, the three critical elements that need to be transferred sequentially, are: identity of the network, access to shared disks and continuous processes.
Based on these and other concepts related to the availability and clustering, Oracle Real Application developed the Cluster (RAC) solution that is a database cluster. RAC requires at least two nodes and it is possible to add more nodes if there is need for more performance, and seen that scalability is one of the goals of this system, there is an internal load balancing according to use in order to improve performance according to the usage pattern. At the heart of the system is Cache Fusion technology is where we share the requests made by clients through the interconnect. In the case of failover, the RAC system uses a virtual IP that is migrated from the failed node and the node chosen to continue the service, verifying the availability of a server is accomplished through a heartbeat mechanism where each node will check availability the other nodes, thus revealing the status of each case and the failure to vote on a node to assume the primary IP.
3. Concluding Remarks
Since the trend is the constant evolution of available technology, just as companies try to keep matched the level of advancement of systems that aims to prevent failures.Systems such as the RAC allow companies to keep their services always active with minimal problems and in case of failures.
For businesses, it is necessary first to consider whether there is real need to invest in this type of system, because it is too expensive to deploy unnecessarily. An example would be the data as one of an insurer in case of need for access, the insured certainly need that after years of investment it is available. Now ready to keep data access need not be a challenge, and investing properly, it is possible to obtain satisfactory results of the prevention of failures that can occur in systems.

An overview of IBM based on its history
Filipi Vaichert de Carvalho
Information Systems
Faculdades Integradas Espírito-santenses (FAESA) – Vitória, ES – Brasil
Abstract.This report describes the presentation made on the IBM territory held by the manager of IBM’s ES, Pimentel Adriano Lemos in FAESA where it presented the history, present and future trends and besides the addition of a vision of the style of IBM.
Resumo. Este relatório descreve a apresentação realizada sobre a IBM realizada pelo gerente de território da IBM no ES, Adriano Pimentel Lemos na FAESA onde o mesmo apresentou a história, presente e tendências para o futuro e além da adição de uma visão do estilo da IBM.
Certainly if this report was meant to expound upon all the information presented in the lecture to which it refers, it would take a book, or rather, an encyclopedia, for which IBM held throughout its history can not be told in mere informational pages . Its history as a company is intertwined with the history of the evolution of the technological world, and in a good deal, IBM was responsible for it. So there will only be the highlight of the main areas seen in the presentation, along with some conjectures about the company’s style and vision of the IT companies today.
2. IBM
Has its origin in 1888, but different from what was said, IBM could be considered today to 114 years, since the company Tabulating Machine Company which was established in 1896 by Herman Hollerith to the U.S. Census Bureau, was first established in the areaComputing trio of companies that joined in 1911 to form the Computing-Tabulating-Recording Company (CTR), which later in 1924 changed its name to International Business Machine (IBM).
Taking the slogan “Think” from his time as CTR, this word can represent what the company actually did over the years. Just for information, among people who have worked at IBM Nobels are five, seven National Medals of Technology, six winners of the Turing Award and eleven people in the Inventors Hall of Fame. Seventeen years is a leader in number of patents and believe that it is perfectly possible to describe how innovation and technology is represented by the company.
Being in approximately 170 countries, operates in several business areas. The main areas are IT services, business services, software and hardware, the latter acting in the server and virtualization to large companies in general.
Premiered in Brazil in 1917 invited by the government to conduct the census, the first subsidiary outside the U.S., and Brazil is currently a major focus among emerging markets.
The program Smart Planet is an idea from IBM for a world where technology helps improve and save lives in all areas, trying to bring benefits to all. Virtually any point can be modified so that the use of technology, actions taken may have greater efficiency.One detail to note is that IBM’s goal is to make these technological advances at the same time selling the solution to any customer who has an interest in it, ie, applications of technology in general has very profitable return for IBM and customer buy the solution.
Being inside the company, you can choose between various options of benefits available to employees, since the alternative mode of working, facilities and personal development plans and career paths. According to a report in the magazine business era, IBM spends about $ 700 million to identify and cultivate talent from around the world and according to Computer World, in 2009 was the 12th best IT company to work for in Brazil. This shows that the company realizes that the people doing the company’s actions are largely responsible for their development and invest in them only brings more results. Among the alternatives, the ones that seemed most interesting was the ability to change positions horizontally, job rotation, and the idea of mentoring, where you look up another employee and it becomes a job coach.
3. The reality of business
According to what was presented, the company takes great care of its employees is one of the most invested in this world, besides being a company that is certainly ahead of its time when the methods used in improving the performance of their employees, butit never ceases to be a company that has as main objective the achievement of profit, using it to their employees.
Drawing a parallel to reality for many companies, we can see that most companies are still aiming to make a profit, but forgets to its professionals, especially in the IT industry.This may reflect data from reports provided by the Standish Group’s indicates that in 2009 only 32% of software development projects were completed successfully. In addition to data from the International Stress Control (Isma) indicate that Brazil is the second most stressed country in the world, being the main reason for this is the job stress, reaching 69% of people.
4. Conclusion
These actions directed to the welfare of employees only bring benefits to the company itself and even small companies can maintain high level of job satisfaction, as is so companies in the country. It should be mirrored at IBM and other large realize that the people who make the company and they should be the main investment and in the case of IBM, were the main reason for today she is one of the leading companies in the world.
I will post here some articles developed between last halfyear, the languages of all article will be writed in Brazilian Portuguese, my native language, and I will translate to put here, and is possible translate instantly with “Translate” below the title of post, probably I will try write something in english but is hard write in another language without english course, like you can see my bad english.
2 articles already available about computer music and 1 new article will be available each 2 days until finish my 8 articles ready.
I will write about books too and my first review will be about “The old man and the sea” by Ernest Hemingway, Nobel Prize in literature. It was read on my Nook and I can tell you, if you love read like me, ebook reader need to be your next acquisition.
Do mesmo modo que se alguém se interessar pelos assuntos e quiser que eu poste o conteúdo em português, só pedir que crio um tópico só pra isso.
Well, enjoy and I will wait your feedback.

An Overview of Computer Music
Dr. Leandro Costalonga (here)
The lecture gave an overview of the PhD thesis developed by Dr. Leandro Costalonga regarding the biomechanical modeling of musical performance with a guitar, it was presented the concepts of musical production and use of computing in this development. Initially presented the use of synthesizers for music production with its implications, thus tests were performed comparing the sound produzidor by these tools with the sound of three professional guitarists, resulting in an interesting conclusion which shows that in general that may differentiate the musical production is the existence of human errors, which allow it to be possible to distinguish between a human and a machine. It was also explained that with the use of artificial intelligence software, there were points that tend to error on the human and musical production with the addition of these variables error in production by machinery, there was almost no distinction between those who produced the music tested.
Among other studies that were throughout the project, one that has been highlighted in relation to the tension of rope used in the guitar, where it was found that the standards currently used are not correct, and with data, breaking paradigms currently used to produce guitars.
An interesting feature of the presentation was to demonstrate the use of various areas of knowledge that are used to produce a scholarly work like this. The study of medicine in the area of biomechanics and physics appear to be very intense to make sense of content, studying muscles in general appears to be not something to be done in computing.
Although the presentation was explained using an apparatus developed to obtain data from three guitarists with an exoskeleton that involved the areas used to play guitar and this can be traced profiles of each musical style. The statistical data presented were for the speed and accuracy together initially and then power and positioning. These data it was possible to discover how easy it is physiologically play a guitar, so that, as is already being used by teachers to teach guitar in a way that students take actions that are easier to drive as initially used in addition to errors that occurred due the physical limitation of the musician.
Then it was explained how to use the software using their libraries WEKA artificial intelligence such as neural networks and nearest neighbor algorithm could find patterns of errors in the three guitarists such as pattern recognition and thus predict the errors according to the musical style and widening musical perfection that tends to human errors to find out where these errors occur so that we can correct, while decreasing the perfection of computers that keep the perfection, limiting them when entering the human physical limitations.

Ubiquitous Computer Music – Music From the Ecocomposition Ubiquitous
Damián Keller (https://ccrma.stanford.edu/~dkeller/)
Initially basing myself on behalf of the lecture, I tried to find some information about what it is and it was really hard to find anything to explain briefly and simply what it would be ubiquitous computer music. Initially I tried computer music, ubiquitous computing and then finally, music ubiquitous. Computer Music is related to the use of computers as an aid or creating music. Ubiquitous computing is a way to create systems that are perceived and used transparently, ie without the need of an effort by the use or used to learn differently from anything natural. Finally, the ubiquitous music, the more difficult to find information, it seemed a bit vague at first, but a definition that seemed well be a descriptive concept of making music in a natural way and to be understood by any person without learning and various sources.
As the subject is very scarce on the Internet, quickly fell into pages that link to Professor Damián Keller, and with it he found references to the Brazilian Symposium on Computer Music in 2009 where in the annals of the event I can find the article titled “Ubiquitous Music: Concepts and Metaphors “containing information about the lecture that could be improved and some concepts that were better explained in the presentation.
When starting the lecture, the professor started talking about the journey all the way from Amazon, collecting sound material for research. Then came the part where the concepts explained some concepts such as epistemic actions and pragmatic actions, where the first is the discovery process, planning and creation, and the second process to perform the actions created and produce a final result. One thing spoken in that article had not understood perfectly well explained at this time, the word affordances, after explaining that I realize that is the set of possible interaction between an agent and the environment. It was also spoken on the framework established for the creation of music, categorizing activities and defining them. There was an explanation of how the concept of arpeggio, which initially I had no idea it would be, but I realize that is just a set of sequential notes, in addition to the theoretical explanation of how to represent the musical creation through the use of evidence that second four stages of development aims to create a musical system, which for me, as an algorithm, you should go up by structuring the sequence result in a final sequence. Still in the same subject was the presentation of mobile software arpeggiator, and then the explanation and display system developed in Java MOW3S, which creates sound by dragging a mouse over an area, and the sound generated is influenced by its position. With the explanation of some sound patterns, which are defined in greater detail in the article, explaining the metaphor of instrumental interaction, which consists of you interact in an instrument to generate sound, the metaphor of the glass, which creates the idea that only to be in a location you can create music without direct interaction and thus generating music from a state, and finally ecocomposição, which would be the kinetic interaction between an agent and any object, but would also own a feedback object with itself. After it was explained and displayed the spoken sound of the exhibition “Urban Corridor”, where using the metaphor of the cup, different sounds are generated based on the position of people who were walking in space. Still was commenting about the study “A Night at the UFAC” where we got data on the relationship between education and music appreciation.
Most of the article and the presentation aims to create a theoretical basis for the beginning of the creation and development of research in the field of computer music ubiquitous, since it is recent in 2005. Many new software that would enable these concepts into practice will be created and still believe this is only the beginning of an area being studied by many others and it is certainly encouraging to know that now and know who started the case after the start, as is a debut.
