  • Une fausse mise à jour d'Android menace les smartphones, Symantec l'a repérée sur un app store chinois

    Une fausse mise à jour d'Android menace les smartphones, Symantec l'a repérée sur un app store chinois Mise à jour du 10.03.2011 par Katleen Symantec vient d'émettre un bulletin d'alerte à propos d'une fausse mise à jour d'Android, qui se révèle en fait être malicieuse et le fruit du travail de hackers. Trompeuse, elle se nomme "Android Market Security Tool" (comme l'application légitime) et semble être basée sur un projet hébergé par Google Code et sous licence Apache. Une fois en place, elle envoie des SMS à un serveur command-and-control. Peu d'autres informations sont actuellement disponibles sur le sujet, puisque Symantec est toujours en train d'analyser le code m...

  • What characters are illegal in Cisco IOS username secret passwords?

    - by Alain O'Dea
    I am using username secret to add users with encrypted passwords to our switches and firewall. I have been battling with the same switches and firewall for a couple of hours trying to get securely generated hard passwords for all admins. Sometimes, the passwords would go into config, but wouldn't work for login. According to the documentation for enable secret a password must not begin with a number and ? has to be entered as Ctrl-V then ? to escape it. I followed that and still got passwords I could not use sometimes. There was no error when I ran username, but the password would be rejected on login by some, but not all of the switches. They are all WS-C2960-48PST-L. The passwords it didn't like contained back ticks "`" (that character under tilde ~ under Esc). The "misbehaving" switches are running: Cisco IOS Software, C2960 Software (C2960-LANBASEK9-M), Version 12.2(50)SE5, RELEASE SOFTWARE (fc1) The "working" switches are running: Cisco IOS Software, C2960 Software (C2960-LANBASEK9-M), Version 12.2(46)SE, RELEASE SOFTWARE (fc2). The "misbehaving" switches are running a newer IOS, so this suggests a regression introduced somewhere between 12.2(46)SE and 12.2(50)SE5. I was unable to find any evidence of this being intentional in the release notes for 12.2(50)SE. I would like to avoid this next time the passwords are changed :) What characters are illegal in Cisco IOS username secret passwords? Thank you for your help :)

  • How to use java ee 6 @Resource annotation

    - by javamonkey79
    The java ee 6 api has an annotation @Resource with an attribute 'lookup', however, so does the java se 6 api (here). However, since java ee 6 is dependent on java se 6, it seems you can not get at the ee version of the annotation and the 'lookup' attribute. Is this a bug or is there some other way to use this annotation that I am missing. TIA

  • Mobile Java Applet?

    - by luvieere
    Is there any mobile platform that allows me to run Java Applets? In absence of browser integration, at least Java SE capabilities. I've heard of a mobile device capable of running Windows XP - that would probably include support for Java SE and applets; does any one have any hands-on experience with such a device? How well does it perform in terms of Java programs execution?

  • Which is the best pick?

    - by Daniel
    Hi, considering I have experience with Java SE: which language should I learn(and is best for that purpose) in order to build web applications some day with it? I have been contemplating PHP and Java EE. The latter does indeed seems as an obvious choice given my Java SE knowledge. But how does it fares in comparison with PHP and how good is it for the aforementioned purpose? If there is a better language for this purpose, feel free to recommend it. Thank you.

  • How to match a variable list of items separated by commas

    - by user261915
    I want to turn something like this CS 240, CS 246, ECE 222, ... (more or less); Software Engineering students only into ('CS 240', 'CS 246', 'ECE 222', 'ECE 220') in Python, code that matches a single course looks like >>> re.search('([A-Z]{2,5} \d{3})', 'SE 112').groups() ('SE 112',) I prefer a regular expression only method because I have a bunch of other alternate reg exps using '|' to combine them. However, a method with split is acceptable.

This now happens every single time. It is imperative that I get it sorted. The strange thing is that it behaves initially then starts to hang after several hours. I perused logs previously and nothing stood out. From the auth.log, I can see that it has allowed me in, but still I get nothing back on the client side: Sep 20 12:47:50 cbear sshd[25376]: Accepted publickey for tfergeson from 10.1.10.14 port 54631 ssh2 Sep 20 12:47:50 cbear sshd[25376]: pam_unix(sshd:session): session opened for user tfergeson by (uid=0) UPDATES: Still occurring even after setting UseDNS no and commenting out #session optional pam_mail.so standard noenv This does not appear to be a network/dns related issue, as all services running on the machine are as responsive and accessible as ever, with the exception of sshd. Any thoughts on where to start?

  • Programação paralela no .NET Framework 4 – Parte I

    - by anobre
    Introdução O avanço de tecnologia nos últimos anos forneceu, a baixo custo, acesso  a workstations com inúmeros CPUs. Facilmente encontramos hoje máquinas clientes com 2, 4 e até 8 núcleos, sem considerar os “super-servidores” com até 36 processadores :) Da wikipedia: A Unidade central de processamento (CPU, de acordo com as iniciais em inglês) ou o processador é a parte de um sistema de computador que executa as instruções de um programa de computador, e é o elemento primordial na execução das funções de um computador. Este termo tem sido usado na indústria de computadores pelo menos desde o início dos anos 1960[1]. A forma, desenho e implementação de CPUs têm mudado dramaticamente desde os primeiros exemplos, mas o seu funcionamento fundamental permanece o mesmo. Fazendo uma analogia, seria muito interessante delegarmos tarefas no mundo real que podem ser executadas independentemente a pessoas diferentes, atingindo desta forma uma  maior performance / produtividade na sua execução. A computação paralela se baseia na idéia que um problema maior pode ser dividido em problemas menores, sendo resolvidos de forma paralela. Este pensamento é utilizado há algum tempo por HPC (High-performance computing), e através das facilidades dos últimos anos, assim como a preocupação com consumo de energia, tornaram esta idéia mais atrativa e de fácil acesso a qualquer ambiente. No .NET Framework A plataforma .NET apresenta um runtime, bibliotecas e ferramentas para fornecer uma base de acesso fácil e rápido à programação paralela, sem trabalhar diretamente com threads e thread pool. Esta série de posts irá apresentar todos os recursos disponíveis, iniciando os estudos pela TPL, ou Task Parallel Library. Task Parallel Library A TPL é um conjunto de tipos localizados no namespace System.Threading e System.Threading.Tasks, a partir da versão 4 do framework. A partir da versão 4 do framework, o TPL é a maneira recomendada para escrever código paralelo e multithreaded. http://msdn.microsoft.com/en-us/library/dd460717(v=VS.100).aspx Task Parallelism O termo “task parallelism”, ou em uma tradução live paralelismo de tarefas, se refere a uma ou mais tarefas sendo executadas de forma simultanea. Considere uma tarefa como um método. A maneira mais fácil de executar tarefas de forma paralela é o código abaixo: Parallel.Invoke(() => TrabalhoInicial(), () => TrabalhoSeguinte()); O que acontece de verdade? Por trás nos panos, esta instrução instancia de forma implícita objetos do tipo Task, responsável por representar uma operação assíncrona, não exatamente paralela: public class Task : IAsyncResult, IDisposable É possível instanciar Tasks de forma explícita, sendo uma alternativa mais complexa ao Parallel.Invoke. var task = new Task(() => TrabalhoInicial()); task.Start(); Outra opção de instanciar uma Task e já executar sua tarefa é: var t = Task<int>.Factory.StartNew(() => TrabalhoInicialComValor());var t2 = Task<int>.Factory.StartNew(() => TrabalhoSeguinteComValor()); A diferença básica entre as duas abordagens é que a primeira tem início conhecido, mais utilizado quando não queremos que a instanciação e o agendamento da execução ocorra em uma só operação, como na segunda abordagem. Data Parallelism Ainda parte da TPL, o Data Parallelism se refere a cenários onde a mesma operação deva ser executada paralelamente em elementos de uma coleção ou array, através de instruções paralelas For e ForEach. A idéia básica é pegar cada elemento da coleção (ou array) e trabalhar com diversas threads concomitantemente. A classe-chave para este cenário é a System.Threading.Tasks.Parallel // Sequential version foreach (var item in sourceCollection) { Process(item); } // Parallel equivalent Parallel.ForEach(sourceCollection, item => Process(item)); Complicado né? :) Demonstração Acesse aqui um vídeo com exemplos (screencast). Cuidado! Apesar da imensa vontade de sair codificando, tome cuidado com alguns problemas básicos de paralelismo. Neste link é possível conhecer algumas situações. Abraços.

  • iiR Hospital Digital 2011: Tras la historia digital ¿qué?

    - by Eloy M. Rodríguez
    Como el acceso a la documentación está restringido, sólo voy a comentar por encima algunos temas o planteamientos que me han llamado la atención del VI Foro Hospital Digital 2011, organizado por iiR. Y comienzo destacando la buena moderación de Maribel Grau del Hospital Clínic de Barcelona que estuvo sobria, eficaz y motivadora del debate. Me impresionó el proyecto Hospital Líquido del Hospital San Joan de Deu de Barcelona por el compromiso corporativo con una medicina colaborativa involucrando a los pacientes y a los profesionales, con unas iniciativas de eSalud y Salud2.0 avanzadas y apoyadas en un buen soporte legal, tecnológico, de los profesionales y con procesos bien definidos. Es un tema corporativo y no una prueba, como bien explicó Jorge Juan Fernández y detalló después Júlia Cutillas, cuyo rol, por cierto, es de Community Manager. En el debate salió el tema del retorno de la inversión y ese es un tema inmaduro, ya que es difícil de encontrar métricas adecuadas, pero no dudan de su continuidad ya que forma parte de una estrategia corporativa, en la que siempre hay elementos que forman parte de los costes generales y que se consideran necesarios para prestar el nivel de servicio que se desea ofrecer. Cecilia Pérez desde su posición como Jefe de Implantación de HCE en el Hospital de Móstoles hizo énfasis en la importancia de la gestión efectiva del cambio cuando se implanta un sistema de historia clínica electrónica que pasa por una inicial negación de los usarios al cambio, que luego presentan una resistencia al prinicipio para luego empezar a explorar posibilidades y llegar a un compromiso con el cambio. Santiago Borrás, Jefe de Sistemas del Hospital del Henares, partió de un hospital digital, pero eso no es más que el comienzo. Tras tres años la frustración de los profesionales es no perderse entre demasiada información. La etapa necesaria tras la digitalición es la generación y compartición del cononocimiento. Cristina Ibarrola, Directora de Atención Primaria del SNS-O comentó la experiencia de las interconsultas primaria-especializada que reducen la carga asistencial en primaria al aumentar la resolución. Hay una reserva de tiempos específicos en las agendas de los profesionales de ambos lados para garantizar una respuesta en un máximo de 48 horas. Eso ha llevado a una flexibiliazación de la agenda de los médicos de primaria que tienen un 25% más de tiempo para las consultas presenciales. Parece que aquí la opción tomada es dar más tiempo por paciente en vez de más pacientes, supongo que en parte porque la presión asistencial en Navarra tengo entendido que no es tan fuerte como en otras zonas. Alejandra Cubero comentó la experiencia de identificación de pacientes y de inteoperabilidad en Hospitales de Madrid. Ana Rosa Pulido presentó los logros del SES y su proyecto actual de Imagen Médica No Radiológica. Richard Bernat explicó la experiencia de HCE de Salud de la Mujer Dexeus, indicando que si bien no hay métricas del retorno de la inversión, sí hay una percepción del valor por las diferentes direcciones. Arturo Quesada glosó la experiencia de Jimena en el Hospital de Ávila, Joan Chafer desgranó el arduo proceso de introducción de sucesivas soluciones digitales en el Hospital Clínico San Carlos de Madrid comenzando por “Hogar Digital”, todo ello con financiación externa o recursos propios y cerró el turno de intervenciones no comerciales Pedro A. Bonal que presentó el valor de los eDocs dentro del Complejo (aplicado en sus dos acepciones de conjunto y complicado) Hospitalario de Toledo como tránsito a la HCE plenamente digital. Tweet

  • Solaris 11 Update 1 - Link Aggregation

    - by Wesley Faria
    Solaris 11.1 No início desse mês em um evento mundial da Oracle chamado Oracle Open World foi lançada a nova release do Solaris 11. Ela chega cheia de novidades, são aproximadamente 300 novas funcionalidade em rede, segurança, administração e outros. Hoje vou falar de uma funcionalidade de rede muito interessante que é o Link Aggregation. O Solaris já suporta Link Aggregation desde Solaris 10 Update 1 porem no Solaris 11 Update 1 tivemos incrementos significantes. O Link Aggregation como o próprio nome diz, é a agregação de mais de uma inteface física de rede em uma interface lógica .Veja agumas funcionalidade do Link Aggregation: · Aumentar a largura da banda; · Imcrementar a segurança fazendo Failover e Failback; · Melhora a administração da rede; O Solaris 11.1 suporta 2(dois) tipos de Link Aggregation o Trunk aggregation e o Datalink Multipathing aggregation, ambos trabalham fazendo com que o pacote de rede seja distribuído entre as intefaces da agregação garantindo melhor utilização da rede.vamos ver um pouco melhor cada um deles. Trunk Aggregation O Trunk Aggregation tem como objetivo aumentar a largura de banda, seja para aplicações que possue um tráfego de rede alto seja para consolidação. Por exemplo temos um servidor que foi adquirido para comportar várias máquinas virtuais onde cada uma delas tem uma demanda e esse servidor possue 2(duas) placas de rede. Podemos então criar uma agregação entre essas 2(duas) placas de forma que o Solaris 11.1 vai enchergar as 2(duas) placas como se fosse 1(uma) fazendo com que a largura de banda duplique, veja na figura abaixo: A figura mostra uma agregação com 2(duas) placas físicas NIC 1 e NIC 2 conectadas no mesmo switch e 2(duas) interfaces virtuais VNIC A e VNIC B. Porem para que isso funcione temos que ter um switch com suporte a LACP ( Link Aggregation Control Protocol ). A função do LACP é fazer a aggregação na camada do switch pois se isso não for feito o pacote que sairá do servidor não poderá ser montado quando chegar no switch. Uma outra forma de configuração do Trunk Aggregation é o ponto-a-ponto onde ao invéz de se usar um switch, os 2 servidores são conectados diretamente. Nesse caso a agregação de um servidor irá falar diretamente com a agregação do outro garantindo uma proteção contra falhas e tambem uma largura de banda maior. Vejamos como configurar o Trunk Aggregation: 1 – Verificando quais intefaces disponíveis # dladm show-link 2 – Verificando interfaces # ipadm show-if 3 – Apagando o endereçamento das interfaces existentes # ipadm delete-ip <interface> 4 – Criando o Trunk aggregation # dladm create-aggr -L active -l <interface> -l <interface> aggr0 5 – Listando a agregação criada # dladm show-aggr Data Link Multipath Aggregation Como vimos anteriormente o Trunk aggregation é implementado apenas 1(um) switch que possua suporte a LACP portanto, temos um ponto único de falha que é o switch. Para solucionar esse problema no Solaris 10 utilizavamos o IPMP ( IP Multipathing ) que é a combinação de 2(duas) agregações em um mesmo link ou seja, outro camada de virtualização. Agora com o Solaris 11 Update 1 isso não é mais necessário, voce pode ter uma agregação de 2(duas) interfaces físicas e cada uma conectada a 1(um) swtich diferente, veja a figura abaixo: Temos aqui uma agregação chamada aggr contendo 4(quatro) interfaces físicas sendo que as interfaces NIC 1 e NIC 2 estão conectadas em um Switch e as intefaces NIC 3 e NIC 4 estão conectadas em outro Swicth. Além disso foram criadas mais 4(quatro) interfaces virtuais vnic A, vnic B, vnic C e vnic D que podem ser destinadas a diferentes aplicações/zones. Com isso garantimos alta disponibilidade em todas a camadas pois podemos ter falhas tanto em switches, links como em interfaces de rede físicas. Para configurar siga os mesmo passos da configuração do Trunk Aggregation até o passo 3 depois faça o seguinte: 4 – Criando o Trunk aggregation # dladm create-aggr -m haonly -l <interface> -l <interface> aggr0 5 – Listando a agregação criada # dladm show-aggr Depois de configurado seja no modo Trunk aggregation ou no modo Data Link Multipathing aggregation pode ser feito a troca de um modo para o outro, pode adcionar e remover interfaces físicas ou vituais. Bem pessoal, era isso que eu tinha para mostar sobre a nova funcionalidade do Link Aggregation do Solaris 11 Update 1 espero que tenham gostado, até uma próxima novidade.

  • Rules and advice for logging?

    - by Nick Rosencrantz
    In my organization we've put together some rules / guildelines about logging that I would like to know if you can add to or comment. We use Java but you may comment in general about loggin - rules and advice Use the correct logging level ERROR: Something has gone very wrong and need fixing immediately WARNING: The process can continue without fixing. The application should tolerate this level but the warning should always get investigated. INFO: Information that an important process is finished DEBUG. Is only used during development Make sure that you know what you're logging. Avoid that the logging influences the behavior of the application The function of the logging should be to write messages in the log. Log messages should be descriptive, clear, short and concise. There is not much use of a nonsense message when troubleshooting. Put the right properties in log4j Put in that the right method and class is written automatically. Example: Datedfile -web log4j.rootLogger=ERROR, DATEDFILE log4j.logger.org.springframework=INFO log4j.logger.waffle=ERROR log4j.logger.se.prv=INFO log4j.logger.se.prv.common.mvc=INFO log4j.logger.se.prv.omklassning=DEBUG log4j.appender.DATEDFILE=biz.minaret.log4j.DatedFileAppender log4j.appender.DATEDFILE.layout=org.apache.log4j.PatternLayout log4j.appender.DATEDFILE.layout.ConversionPattern=%d{HH:mm:ss,SSS} %-5p [%C{1}.%M] - %m%n log4j.appender.DATEDFILE.Prefix=omklassning. log4j.appender.DATEDFILE.Suffix=.log log4j.appender.DATEDFILE.Directory=//localhost/WebSphereLog/omklassning/ Log value. Please log values from the application. Log prefix. State which part of the application it is that the logging is written from, preferably with something for the project agreed prefix e.g. PANDORA_DB The amount of text. Be careful so that there is not too much logging text. It can influence the performance of the app. Loggning format: -There are several variants and methods to use with log4j but we would like a uniform use of the following format, when we log at exceptions: logger.error("PANDORA_DB2: Fel vid hämtning av frist i TP210_RAPPORTFRIST", e); In the example above it is assumed that we have set log4j properties so that it automatically write the class and the method. Always use logger and not the following: System.out.println(), System.err.println(), e.printStackTrace() If the web app uses our framework you can get very detailed error information from EJB, if using try-catch in the handler and logging according to the model above: In our project we use this conversion pattern with which method and class names are written out automatically . Here we use two different pattents for console and for datedfileappender: log4j.appender.CONSOLE.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n log4j.appender.DATEDFILE.layout.ConversionPattern=%d [%t] %-5p %c - %m%n In both the examples above method and class wioll be written out. In the console row number will also be written our. toString() Please have a toString() for every object. EX: @Override public String toString() { StringBuilder sb = new StringBuilder(); sb.append(" DwfInformation [ "); sb.append("cc: ").append(cc); sb.append("pn: ").append(pn); sb.append("kc: ").append(kc); sb.append("numberOfPages: ").append(numberOfPages); sb.append("publicationDate: ").append(publicationDate); sb.append("version: ").append(version); sb.append(" ]"); return sb.toString(); } instead of special method which make these outputs public void printAll() { logger.info("inbet: " + getInbetInput()); logger.info("betdat: " + betdat); logger.info("betid: " + betid); logger.info("send: " + send); logger.info("appr: " + appr); logger.info("rereg: " + rereg); logger.info("NY: " + ny); logger.info("CNT: " + cnt); } So is there anything you can add, comment or find questionable with these ways of using the logging? Feel free to answer or comment even if it is not related to Java, Java and log4j is just an implementation of how this is reasoned.

  • Oracle at ARM TechCon

    - by Tori Wieldt
    ARM TechCon is a technical conference for hardware and software engineers, Oct. 30-Nov 1 in Santa Clara, California. Days two and three of the conference will be geared towards systems designers and software developers, those interested in building ARM processor-based modules, boards, and systems. It will cover all of the hardware and software, tools, ranging from low-power design, networking and connectivity, open source software, and security. Oracle is a sponsor of ARM TechCon, and will present three Java sessions and a hands-on-lab:  "Do You Like Coffee with Your Dessert? Java and the Raspberry Pi" - The Raspberry Pi, an ARM-powered single board computer running a full Linux distro off an SD card has caused a huge wave of interest among developers. This session looks at how Java can be used on a device such as this. Using Java SE for embedded devices and a port of JavaFX, the presentation includes a variety of demonstrations of what the Raspberry Pi is capable of. The Raspberry Pi also provides GPIO line access, and the session covers how this can be used from Java applications. Prepare to be amazed at what this tiny board can do. (Angela Caicedo, Java Evangelist) "Modernizing the Explosion of Advanced Microcontrollers with Embedded Java" - This session explains why Oracle Java ME Embedded is the right choice for building small, connected, and intelligent embedded solutions, such as industrial control applications, smart sensing, wireless connectivity, e-health, or general machine-to-machine (M2M) functionality---extending your business to new areas, driving efficiency, and reducing cost. The new Oracle Java ME Embedded product brings the benefits of Java technology to microcontroller platforms. It is a full-featured, complete, compliant software runtime with value-add features targeted to the embedded space and has the ability to interface with additional hardware components, remote manageability, and over-the-air software updates. It is accompanied by a feature-rich set of tools free of charge. (Fareed Suliman, Java Product Manager) "Embedded Java in Smart Energy and Healthcare" - This session covers embedded Java products and technologies that enable smart and connect devices in the Smart Energy and Healthcare/Medical industries. (speaker Kevin Lee) "Java SE Embedded Development on ARM Made Easy" - This Hands-on Lab aims to show that developers already familiar with the Java develop/debug/deploy lifecycle can apply those same skills to develop Java applications, using Java SE Embedded, on embedded devices. (speaker Jim Connors) In the Oracle booth #603, you can see the following demos: Industry Solutions with JavaThis exhibit consists of a number of industry solutions and how they can be powered by Java technology deployed on embedded systems.  Examples in consumer devices, home gateways, mobile health, smart energy, industrial control, and tablets all powered by applications running on the Java platform are shown.  Some of the solutions demonstrate the ability of Java to connect intelligent devices at the edge of the network to the datacenter or the cloud as a total end-to-end platform.Java in M2M with QualcommThis station will exhibit a new M2M solutions platform co-developed by Oracle and Qualcomm that enables wireless communications for embedded smart devices powered by Java, and share the types of industry solutions that are possible.  In addition, a new platform for wearable devices based on the ARM Cortex M3 platform is exhibited.Why Java for Embedded?Demonstration platforms will show how traditional development environments, tools, and Java programming skills can be used to create applications for embedded devices.  The advantages that Java provides because of  the runtime's abstraction of software from hardware, modularity and scalability, security, and application portability and manageability are shared with attendees. Drop by and see why Java is an optimal applications platform for embedded systems.
