  • Change find() type of contained model or array transformation

    - by Ramon Marco Navarro
    I have the following model associations: Response->Survey Response->Question Response->Choice Survey->Question Question->Choice I want to create a form where I could answer all the questions for one survey. So I used the following to return the needed data: $questions = $this->Response->Question->find('all', array( 'conditions' => array('survey_id' => $id), 'contain' => array('Choice') ) ); Sample output for debug($questions). Questions Is there a contain() option so that an associated model returns in the find('list') format so that I could use: foreach($question as $questions) { $this-Form-select('field_name', $question['Choice']); } If no option is available, how could I do this using PHP's builting array methods? PS: The foreach block won't turn into a code block. If someone could edit and fix it, please do so and delete this line. Thank you.

  • how to calculate power consumption on an Android mobile that uses wifi?

    - by Marco
    Hello, I have implemented a routing protocol on an Android 1.6 mobile that uses wireless (ad-hoc) network in order to exchange messages. Now I would like to evaluate it under an energy consumption point of view, the base would be to try to calculate the energy wasted to transmit a single packet, do anybody has any idea how to do that? Software/hardware solutions are welcome! Thanx :)

    - by Marco
    lets say i have a group of number like (3,2,5) the normal way i use to split them and searching mysql to get value is to split them using explode in PHP EXAMPLE $string = '3,4,5'; $array = explode(',',$string); foreach($array as $value){ $query = 'SELECT ID FROM TABLE WHERE ID = "'.$value.'"'; } it work like this but it make the script extremely slow i need now if there is away to split this string into the query it self and return the result without looping with PHP ?

El Dialogo CxO , organizado por Econique, y en el que participó Oracle, tuvo lugar en Madrid en el Hotel Puerta de Ámerica. Este encuentro tenía como objetivo intercambiar opiniones sobre todos los aspectos relacionados con la gestión estratégica de clientes y el Contact Centre. En este marco, los asistentes tuvieron la oportunidad de realizar reuniones “one to one” con nuestros mejores expertos. Además Oracle presentó dos coloquios relacionados con la visión de las "Nuevas necesidades, estrategias y tendencias en la gestión del Marketing", de la mano de Gema Sebastian, Principal Sales Consultant de Oracle. En dichos coloquios los participantes de empresas, como Caprabo, Carrefour, Endesa, Jaguar Land Rover y Repsol (entre otros) trataron temas de máxima actualidad para los directivos de Marketing. Esta mesa redonda se centró sobre todo en el Marketing en redes sociales, compartiendo entre todos nuestra percepción de que es algo necesario pero que todavía el mercado no sabe muy bien cómo tratar. La escucha activa dentro de las redes y la posibilidad de reaccionar ante determinados factores se veía como un claro punto donde comenzar a trabajar de manera activa y donde Oracle puede ayudar. La experiencia de cliente fue otro de los puntos tratados en esta mesa, donde se dejó claro que ahora es el consumidor el que manda, el que quiere ver las cosas donde quiere y como quiere y que un mensaje de marketing ha de darse en el momento adecuado y aportando un valor real para que el consumidor lo acepte como algo interesante. Igualmente Oracle dispone de herramientas para hacer que esto sea posible. Por otro lado, en Lisboa, tenía lugar el Total Training 2012, una conferencia organizada por el Grupo IFE. En ella participaron más de 100 profesionales de los recursos humanos de las empresas más importantes de Portugal y tuvo como base de partida los conocimientos y experiencias, el intercambio de ideas y la discusión de oportunidades a las que actualmente se enfrentan los profesionales de este área. En este marco Oracle realizó una ponencia sobre “Los nuevos conceptos en RRHH”, de la mano de Julio Rodriguez, Principal Sales Consultant de Oracle, y que puso de manifiesto algunos conceptos tecnológicos relevantes para la gestión del talento que por su novedad, no eran muy conocidos por los profesionales de los RRHH cómo: · Saas (Software as a service) · BI (Business Intelligence) para RRHH · Social Networking y cómo integrarla dentro de la empresa · El mapa del talento, por fin fuera del Excel y en una aplicación · La movilidad en las aplicaciones de RRHH. Sin duda, esta fue una jornada cargada de intercambio de experiencias y de conocimientos para dos grandes áreas: los Recursos Humanos y la Gestión Estratégica del cliente.

  • Should concrete classes avoid calling other concrete classes, except for data objects?

    - by Kazark
    In Appendix A to The Art of Unit Testing, Roy Osherove, speaking about ways to write testable code from the start, says, An abstract class shouldn't call concrete classes, and concerete classes shouldn't call concrete classes either, unless they're data objects (objects holding data, with no behavior). (259) The first half of the sentence is simply Dependency Inversion from SOLID. The second half seems rather extreme to me. That means that every time I'm going to write a class that isn't a simple data structure, which is most classes, I should write an interface or abstract class first, right? Is it really worthwhile to go that far in defining abstract classes an interfaces? Can anyone explain why in more detail, or refute it in spite of its benefit for testability?

  • OOW 2012: Slides Download

    - by Mike Dietrich
    Hm ... you might ask yourself why there are no Oracle Database 12c slides available for download, neither in the OOW 2012 content system nor on our blog (and I believe nowhere else). Simple reason: As long as Oracle Database 12c is not released and available we are not allowed to offer slides for download. Therefore people were simply taking pictures during the 12c sessions with their phones, iPods and cameras. Roy took a nice shot: Sorry for that - we'll make the content available as soon as Oracle Database 12c gets released. In between you can download our OOW 2012 talk Database Upgrades on Steroids: Real Speed, Real Customers, Real Secrets as PDF (3.4MB) - but the 12c content is currently not in that PDF. But a lot of information applies to your source database and/or to any upgrade - so it still might be helpful. And unfortunately the same 12c rule applies to the slides guiding you through our Hands-On-Lab on Tuesday. Thanks

  • Anyone else experiencing high rates of Linux server crashes during a leap second day?

    - by Bron Gondwana
    POSTMORTEM Anticlimax: only thing that died was my VPN (openvpn) link to the cluster, so there was an exciting few seconds while it re-established. Everything else was fine. Starting back ntp everywhere. If you look at Marco's blog at http://my.opera.com/marcomarongiu/blog/2012/06/01/an-humble-attempt-to-work-around-the-leap-second - he has a solution for phasing the time change over 24 hours using ntpd -x to avoid the 1 second skip. Give that a go if it matters to you. For the systems I run, the jump isn't a problem. Just today, Sat June 30th - starting soon after the start of the day GMT. We've had a handful of blades in different datacentres as managed by different teams all go dark - not responding to pings, screen blank. They're all running Debian Squeeze - with everything from stock kernel to custom 3.2.21 builds. Most are Dell M610 blades, but I've also just lost a Dell R510 and other departments have lost machines from other vendors too. There was also an older IBM x3550 which crashed and which I thought might be unrelated, but now I'm wondering. The one crash which I did get a screen dump from said: [3161000.864001] BUG: spinlock lockup on CPU#1, ntpd/3358 [3161000.864001] lock: ffff88083fc0d740, .magic: dead4ead, .owner: imapd/24737, .owner_cpu: 0 Unfortunately the blades all supposedly had kdump configured, but they died so hard that kdump didn't trigger - and they had console blanking turned on. I've disabled console blanking now, so fingers crossed I'll have more information after the next crash. Just want to know if it's a common thread or "just us". It's really odd that they're different units in different datacentres bought at different times and run by different admins (I run the FastMail.FM ones)... and now even different vendor hardware. Most of the machines which crashed had been up for weeks/months and were running 3.1 or 3.2 series kernels. The most recent crash was a machine which had only been up about 6 hours running 3.2.21. THE WORKAROUND Ok people, here's how I worked around it. disabled ntp: /etc/init.d/ntp stop created http://linux.brong.fastmail.fm/2012-06-30/fixtime.pl (code stolen from Marco, see blog posts in comments) ran fixtime.pl without an argument to see that there was a leap second set ran fixtime.pl with an argument to remove the leap second NOTE: depends on adjtimex. I've put a copy of the squeeze adjtimex binary at http://linux.brong.fastmail.fm/2012-06-30/adjtimex - it will run without dependencies on a squeeze 64 bit system. If you put it in the same directory as fixtime.pl, it will be used if the system one isn't present. Obviously if you don't have squeeze 64 bit... find your own. I'm going to start ntp again tomorrow. As an anonymous user suggested - an alternative to running adjtimex is to just set the time yourself, which will presumably also clear the leapsecond counter.

  • How to view Session Variables in Visual Studio 2008 Debugger?

    Usually using Visual Studio's debugger is a breeze. Scanning through Locals quickly shows the values of variables, etc. However, I'm at a loss how to find out the values contained in session state variables? Can anyone give me a hand? Lets say I put a breakpoint right after: Session("first_name") = "Rob Roy" How do I view the value contained in Session("first_name") from locals?

  • Session Mania: Content Catalog & Suggest-a-Session

    - by Justin Kestelyn
    As ably reported in the Oracle Technology Network blog, the Oracle Develop Conference's content catalog is now public (as are the catalogs for JavaOne and Oracle OpenWorld), meaning you can now explore technical sessions scheduled for the conf to your heart's content."But something's missing", you may tell yourself. "Where is my favorite subject, the one I happen to also be an expert on?" Well, there's good news for you, too: The Suggest-A-Session project has returned. It works thus: Submit a session idea via Oracle Mix and ask your colleagues, Oracle Mix community, friends and anyone else you know to vote for your session. (You must be an Oracle Mix member to vote.) Voting is open through June 20. For the most part, the top voted sessions will be selected for the Oracle Develop Conf (or Oracle OpenWorld) official agenda. See the FAQ for fine print.Apparently some people have already jumped into this loophole, including Oracle ACE Director Marco Gralike, who has "gone video" on us: Why wait? Suggest-a-session!

  • Embedded Spark 2010 Summer Challenge

    - by Valter Minute
    If you have a good idea for a cool embedded device based on Windows Embedded 7 and some free time to work on it you can partecipate to the Embedded Spark 2010 Summer Challenge. Just submit a short paper describing your idea and, if your idea is one of the 75 selected by the judges, you’ll receive some hardware to put your idea in practice and a chance to attend ESC Boston for free and win 15.000 dollars. The latest challenge has been won by Marco Bodoira, a fellow Italian embedded developer, so I hope to see many Italian developers (and non developers) presenting their ideas and project for this new challenge! You can find rules, ideas, forums and all the information you need at the challenge web site: http://www.embeddedspark.com/
