  • Automatically registering "commands" for a command line program in python

    - by seandavi
    I would like to develop a command-line program that can process and give "help" for subcommands. To be concrete, say I have a single script called "cgent" and I would like to have subcommands "abc", "def", and "xyz" execute and accept the rest of the sys.args for processing by optparse. cgent abc [options] cgent help abc .... All of this is straightforward if I hard-code the subcommand names. However, I would like to be able to continue to add subcommands by adding a class or module (?). This is similar to the idea that is used by web frameworks for adding controllers, for example. I have tried digging through pylons to see if I can recreate what is done there, but I have not unravelled the logic. Any suggestions on how to do this? Thanks, Sean

  • Motores tecnológicos para el crecimiento económico

    - by Fabian Gradolph
    Oracle ha participado hoy en el IV Curso de Verano AMETIC-UPM. La presentación a corrido a cargo de José Manuel Peláez, director de Preventa de Tecnología de Oracle Ibérica, quien ha hecho una completa revisión de cuáles son los impulsores actuales de la innvovación y del desarrollo en el entorno de las tecnologías, haciendo honor al título del curso:  Las TIC en el nuevo entorno socio-económico: Motores de la recuperación económica y el empleo. Peláez, en su presentación "De la tecnología a la innovación: impulsores de la actividad económica",  ha comenzado destacando la importancia estratégica que hoy en día tienen las tecnologías para cualquier modelo de negocio. No se trata ya de hacer frente a la crisis económica, que también, sino sobre todo de hacer frente a los desafíos presentes y futuros de las empresas. En este sentido, es esencial hacer frente a un reto: el alto coste que tiene para las organizaciones la complejidad de sus sistemas tecnológicos. Hay un ejemplo que Oracle utiliza con frecuencia. Si un coche se comprase del mismo modo en que las empresas adquieren los sistemas de información, compraríamos por un lado la carrocería, por otro lado el motor, las ventanas, el cambio de marchas, etc... y luego pasaríamos un tiempo muy interesante montándolo todo en casa. La pregunta clave es: ¿por qué no adquirir los sistemas de información ya preparados para funcionar, al igual que compramos un coche?. El sector TI, con Oracle a la cabeza, está dando uina respuesta adecuada con los sistemas de ingenería conjunta. Se trata de sistemas de hardware y software diseñados y concebidos de forma integrada que reducen considerablemente el tiempo necesario para la implementación, los costes de integración y los costes de energía y mantenimiento. La clave de esta forma de adquirir la tecnología, según ha explicado Peláez, es que al reducir la complejidad y los costes asociados, se están liberando recursos que pueden dedicarse a otras necesidades. Según los datos de Gartner, de la cantidad de recursos invertidos por las empresas en TI, el 63% se dedica a tareas de puro funcionamiento, es decir, a mantener el negocio en marcha. La parte de presupuesto que se dedica a crecimiento del negocio es el 21%, mientras que sólo un 16% se dedica a transformación, es decir, a innovación. Sólo mediante la utilización de tecnologías más eficientes -como los sistemas de ingeniería conjunta-, que lleven aparejados menores costes, es viable reducir ese 63% y dedicar más recursos al crecimiento y la innovación. Ahora bien, una vez liberados los recursos económicos, ¿hacia dónde habría que dirigir las inversiones en tecnología?. José Manuel Peláez ha destacado algunas áreas esenciales como son Big Data, Cloud Computing, los retos de la movilidad y la necesidad de mejorar la experiencia de los clientes, entre otros. Cada uno de estos aspectos lleva aparejados nuevos retos empresariales, pero sólo las empresas que sean capaces de integrarlos en su ADN e incorporarlos al corazón de su estrategia de negocio, podrán diferenciarse en el panorama competitivo del siglo XXI. Desde estas páginas los iremos desgranando poco a poco.

  • National Give Camp Weekend - January 14-16, 2011

    - by MOSSLover
    What is a Give Camp?  I get asked this question constantly in the SharePoint Community.  About 3 years ago there was an event called "We Are Microsoft" in Dallas, TX.  A lady named, Toi Wright, gathered up a bunch of charities and gathered up a bunch of IT Professionals in the community.  They met for an entire weekend devising better ways to help these charities with 3 days projects.  None of these charities had in house IT staff or they were lacking.  The time these projects would save would help out other people in the long run.  The first give camp was really popular that a couple guys from Kansas City decided to come up with a give camp in the Kansas City regiona.  The event was called Coders 4 Charity.  I read Jeff Julian's post on the "We Are Microsoft" event that it inspired me to get involved.  i showed up to this event and we were split into teams.  On that team I met a couple really awsome guys: Blake Theiss, Lee Brandt, Tim Wright, and Joe Loux.  We created a SharePoint site for a boyscout troup.  It was my first exposure to Silverlight 1.1.  I had so much fun that I attended the event the next year and the St. Louis Coders 4 Charity.  Last year in 2010 when I moved i searched high and low.  Sure enough they had an event in Philadelphia.  I helped out with two SharePoint Projects for a team of firefighters and another charity.  This year there are a series of give camps around the U.S.  They have consolidated most of the give camps.  The first ever New York City Give Camp is on National Give Camp Day.  If you guys are interested I see there is a give camp in Philadelphia, St. Louis, Northwest Arkansas, Seattle, Atlanta, Houston, and more...Here is a link to the site I would definitely encourage you to get involved: http://givecamp.org/national-givecamp/.  Also, if you feel like it's only developer focused that's entirely wrong.  They need DBAs, Project Leads, Architects, and many other roles fulfilled aside from development.  It is a great experience to meet good people and help out a charity doing what we all love to do.  I strongle encourage getting involved in a give camp.  if you are coming to the NYC Give Camp I would love to meet you.  i will be there on Saturday somewhere in the morning until around dinner time.

  • Mostrar Imagenes en ListView utilizando ImageList WinForms

    - by Jason Ulloa
    El día de hoy veremos como trabajar con los controles ListView e Imagelist de WindowsForms para poder leer y mostrar una serie de imágenes. Antes de ello debo decir que pueden existir otras formas de mostrar imagenes que solo requieren un control por ejemplo con un Gridview pero eso será en otro post, ahora nos centraremos en la forma de realizarlo con los controles antes mencionados. Lo primero que haremos será crear un nuevo proyecto de windows forms, en mi caso utilizando C#, luego agregaremos un Control ImageList. Este control será el que utilicemos para almacenar todas las imágenes una vez que las hemos leído. Si revisamos el control, veremos que tenemos la opción de agregar la imágenes mediante el diseñador, es decir podemos seleccionarlas manualmente o bien agregarlas mediante código que será lo que haremos. Lo segundo será agregar un control ListView al Formulario, este será el encargado de mostrar las imagenes, eso sí, por ahora será solo mostrarlas no tendrá otras funcionalidades. Ahora, vamos al codeBehind y en el Evento Load del form empezaremos a codificar: Lo primero será, crear una nueva variable derivando DirectoryInfo, a la cual le indicaremos la ruta de nuestra carpeta de imágenes. En nuestro ejemplo utilizamos Application.StartUpPath para indicarle que vamos a buscar en nuestro mismo proyecto (en carpeta debug por el momento). DirectoryInfo dir = new DirectoryInfo(Application.StartupPath + @"\images");   Una vez que hemos creado la referencia a la ruta, utilizaremos un for para obtener todas la imágenes que se encuentren dentro del Folder que indicamos, para luego agregarlas al imagelist y empezar a crear nuestra nueva colección. foreach (FileInfo file in dir.GetFiles()) { try { this.imageList1.Images.Add(Image.FromFile(file.FullName)); }   catch { Console.WriteLine("No es un archivo de imagen"); } }   Una vez, que hemos llenado nuestro ImageList, entonces asignaremos al ListView sus propiedades, para definir la forma en que las imágenes se mostrarán. Un aspecto a tomar en cuenta acá será la propiedad ImageSize ya que está será la que definirá el tamaño que tendrán las imágenes en el ListView cuando sean mostradas. this.listView1.View = View.LargeIcon;   this.imageList1.ImageSize = new Size(120, 100);   this.listView1.LargeImageList = this.imageList1;   Por último y con ayuda de otro for vamos a recorrer cada uno de los elementos que ahora posee nuestro ImageList y lo agregaremos al ListView para mostrarlo for (int j = 0; j < this.imageList1.Images.Count; j++) { ListViewItem item = new ListViewItem();   item.ImageIndex = j;   this.listView1.Items.Add(item); } Como vemos, a pesar de que utilizamos dos controles distintos es realmente sencillo  mostrar la imagenes en el ListView al final el control ImageList, solo funciona como un “puente” que nos permite leer la imagenes para luego mostrarlas en otro control. Para terminar, los proyectos de ejemplo: C# VB

  • Why is there nobody talking about an alternative to HTML & CSS? [closed]

    - by Nic
    HTML is such an old and cumbersome language, which was intended just to markup text. Today it's very rare to see a static HTML website, or a site with only text or a very simple layout. As a web developer I find it inconvenient to use HTML & CSS, very repetitive and cumbersome. I think that for a lot of website it could be simplified a lot. Tim Berners-Lee (W3) wrote a document named "The World Wide Web: Past, Present and Future" in August 1996 ... though HTML will be considered part of the established infrastructure (rather than an exciting new toy), there will always be new formats coming along, and it may be that a more powerful and perhaps a more consistent set of formats will eventually displace HTML. So, more than 15 years later, HTML is still here and it's here to stay. Why? Why searching for xml alternatives brings so much relevant result, but searching for html alternatives brings almost none relevant results? Answers like "it's too hard to change a standard" aren't answering the question since a lot of new standards emerged since the initiation of the web. I'm also not searching for answers that suggest using tools to simplify the process or formats that anyhow depends on HTML or CSS, technologies that currently require a plugin and not even trying to become an open standards (like Flash) aren't an answer neither. BTW, here are 2 articles written more than two years ago as food for thought, it might help with writing a better answers. "HTML, CSS, and Web Development Practices: Past, Present, and Future" describing a very related problem, by Jens O. Meiert. "A Brief History of HTML" by Scott Reynen, Here is a quote from the end: So now you can answer questions about HTML5 without even looking at the draft, which is handy, because the draft is 400+ pages long. Why is there a new tag in HTML5? Because some browser vendor (maybe the one that also owns a large video site) wanted it. Why are there so many scriptable interface elements in HTML5? Because some browser vendor (maybe the one selling phones without Flash support) wants them. Why is there no support for RDFa in HTML5? Apparently no browser vendor wanted it. Is that the future?

  • "Well, Swing took a bit of a beating this week..."

    - by Geertjan
    One unique aspect of the NetBeans community presence at JavaOne 2012 was its usage of large panels to highlight and discuss various aspects (e.g., Java EE, JavaFX, etc) of NetBeans IDE usage and tools. For example, here's a pic of one of the panels, taken by Markus Eisele: Above you see me, Sean Comerford from ESPN.com, Gerrick Bivins from Halliburton, Angelo D'Agnano and Ioannis Kostaras from the NATO Programming Center, and Çagatay Çivici from PrimeFaces. (And Tinu Awopetu was also on the panel but not in the picture!) On one of those panels a remark was made which has kind of stuck with me. Henry Arousell, a member of the "NetBeans Platform Discussion Panel", who works on accounting software in Sweden, together with Thomas Boqvist, who was also at JavaOne, said, a bit despondently, I thought, the following words at the start of the demo of his very professional looking accounting software: "Well, Swing took a bit of a beating this week..." That remark comes in the light of several JavaFX sessions held at JavaOne, together with many sessions from the web and mobile worlds making the argument that the browser, tablet, and mobile platforms are the future of all applications everywhere. However, then I had another look at the list of Duke's Choice Award winners: http://www.oracle.com/us/corporate/press/1854931 OK, there are 10 winners of the Duke's Choice Award this year. Three of them (JDuchess, London Java Community, Student Nokia Developer Group) are not awards for software, but for people or groups. So, that leaves seven awards. Three of them (Hadoop, Jelastic, and Parleys) are, in one way or another, some kind of web-oriented solution, though both Hadoop and Jelastic are broader than that, but are service-oriented solutions, relating to cloud technologies. That leaves four others: NATO air defense software, Liquid Robotics software, AgroSense software, and UNHCR Refugee Registration software. All these are, on the software level, Java desktop solutions that, on the UI layer, make use of Java Swing, together with LuciadMaps (NATO), GeoToolkit (AgroSense), and WorldWind (Liquid Robotics). (And, it went even further than that, i.e., this is not passive usage of Swing but active and motivated: Timon Veenstra, during his AgroSense demo, said "There are far more Swing applications out there than we seem to think. Web developers just make more noise." And, during his Liquid Robotics demo, James Gosling said: "Not everything can be done in HTML.") Seems to me that Java Swing was the enabler of more Duke's Choice Award winners this year than any other UI-oriented Java technology. Now, I'm not going to interpret that one way or another, since I've noticed that interpretations of facts tend to validate some underlying agenda. Take any fact anywhere and you can interpret it to prove whatever opinion you're already holding to be true. Therefore, no interpretation from me. Simply stating the fact that Swing, far from taking a beating during JavaOne 2012, was a more significant user interface enabler of Duke's Choice Award winners than any other Java user interface technology. That's not an interpretation, but a fact.

  • 24HOP gets off to a good start

    - by Rob Farley
    Session 11 is on as I write this – Ami Levin presenting about Primary Keys. It’s a good session. But actually, they’ve all been excellent so far, not just Ami’s. I’ve heard only good things about the content. So if you’re reading this and 24HOP is still on, then tune in and take part. If it’s finished, get yourself over to http://sqlpass.org/24hours and see if the sessions have been made available on-demand. Yes – you should be able to watch the sessions when you want to for a year. Watching live is best, because you can ask questions and have them answered during the session, but if there are ones you just couldn’t make, then watching them on-demand is a good option. Numbers have been “not bad”. At the moment it’s still the middle of the night for most Americans – about 6:30am in New York, and yet we’ve had well over a hundred at all the sessions so far, getting up to well over 300 for some sessions. And when I look through the list of names, I see a bunch of names that suggest we’re reaching people from all around the world. I’m seriously looking forward to seeing the stats about which countries have been represented in the audiences. There have been a few comments about the platform. Everyone seems to consider IBTalk an improvement on LiveMeeting, but the closed captioning has met a mixed reception. Some people are loving it, whereas other people are finding the translations leave quite a bit of space for improvement. If you have feedback on this, please feel free to drop me an email (my name with an underscore at hotmail.com, or with a dot at sqlpass.org should reach me just fine, or Twitter, etc). I don’t know how many of the sessions I’ll get to watch overnight – but I’m looking forward to seeing how things go as the day progresses. Big thanks to everyone who’s involved – the sponsors, PASS HQ team and the IBTalk folk who have stayed up overnight to facilitate, plus the moderators, the people doing the live captioning, and of course the speakers and attendees. I love how the SQL Community gets behind things like this. Earlier, the Adelaide SQL Server User Group gathered and watched Denny Lee’s session on BigData, and everyone in the group agreed that it worked really well. I took a picture of our cinema room, although you could only see a small section of the audience. @rob_farley

  • JUDCon 2013 Trip Report

    - by reza_rahman
    JUDCon (JBoss Users and Developers Conference) 2013 was held in historic Boston on June 9-11 at the Hynes Convention Center. JUDCon is the largest get together for the JBoss community, has gone global in recent years but has it's roots in Boston. The JBoss folks graciously accepted a Java EE 7 talk from me and actually referenced my talk in their own sessions. I am proud to say this is my third time speaking at JUDCon/the Red Hat Summit over the years (this was the first time on behalf of Oracle). I had great company with many of the rock stars of the JBoss ecosystem speaking such as Lincoln Baxter, Jay Balunas, Gavin King, Mark Proctor, Andrew Lee Rubinger, Emmanuel Bernard and Pete Muir. Notably missing from JUDCon were Bill Burke, Burr Sutter, Aslak Knutsen and Dan Allen. Topics included Java EE, Forge, Arquillian, AeroGear, OpenShift, WildFly, Errai/GWT, NoSQL, Drools, jBPM, OpenJDK, Apache Camel and JBoss Tools/Eclipse. My session titled "JavaEE.Next(): Java EE 7, 8, and Beyond" went very well and it was a full house. This is our main talk covering the changes in JMS 2, the Java API for WebSocket (JSR 356), the Java API for JSON Processing (JSON-P), JAX-RS 2, JPA 2.1, JTA 1.2, JSF 2.2, Java Batch, Bean Validation 1.1, Java EE Concurrency and the rest of the APIs in Java EE 7. I also briefly talked about the possibilities for Java EE 8. The slides for the talk are here: JavaEE.Next(): Java EE 7, 8, and Beyond from reza_rahman Besides presenting my talk, it was great to catch up with the JBoss gang and attend a few interesting sessions. On Sunday night I went to one of my favorite hangouts in Boston - the exalted Middle East Club as Rolling Stone refers to it (other cool spots in an otherwise pretty boring town is "the Church"). As contradictory as it might sound to the uninitiated, the Middle East Club is possibly the best place in Boston to simultaneously get great Middle Eastern (primarily Lebanese) food and great underground metal. For folks with a bit more exposure, this is probably not contradictory at all given bands like Acrassicauda and documentaries like Heavy Metal in Baghdad. Luckily for me they were featuring a few local Thrash metal bands from the greater Boston area. It wasn't too bad considering it was primarily amateur twenty-something guys (although I'm not sure I'm a qualified critic any more since I all but stopped playing about at that age). It's great Boston has the Middle East as an incubator to keep the rock, metal, folk, jazz, blues and indie scene alive. I definitely enjoyed JUDCon/Boston and hope to be part of the conference next year again.

  • Bullet Physics implementing custom MotionState class

    - by Arosboro
    I'm trying to make my engine's camera a kinematic rigid body that can collide into other rigid bodies. I've overridden the btMotionState class and implemented setKinematicPos which updates the motion state's tranform. I use the overridden class when creating my kinematic body, but the collision detection fails. I'm doing this for fun trying to add collision detection and physics to Sean O' Neil's Procedural Universe I referred to the bullet wiki on MotionStates for my CPhysicsMotionState class. If it helps I can add the code for the Planetary rigid bodies, but I didn't want to clutter the post. Here is my motion state class: class CPhysicsMotionState: public btMotionState { protected: // This is the transform with position and rotation of the camera CSRTTransform* m_srtTransform; btTransform m_btPos1; public: CPhysicsMotionState(const btTransform &initialpos, CSRTTransform* srtTransform) { m_srtTransform = srtTransform; m_btPos1 = initialpos; } virtual ~CPhysicsMotionState() { // TODO Auto-generated destructor stub } virtual void getWorldTransform(btTransform &worldTrans) const { worldTrans = m_btPos1; } void setKinematicPos(btQuaternion &rot, btVector3 &pos) { m_btPos1.setRotation(rot); m_btPos1.setOrigin(pos); } virtual void setWorldTransform(const btTransform &worldTrans) { btQuaternion rot = worldTrans.getRotation(); btVector3 pos = worldTrans.getOrigin(); m_srtTransform->m_qRotate = CQuaternion(rot.x(), rot.y(), rot.z(), rot.w()); m_srtTransform->SetPosition(CVector(pos.x(), pos.y(), pos.z())); m_btPos1 = worldTrans; } }; I add a rigid body for the camera: // Create rigid body for camera btCollisionShape* cameraShape = new btSphereShape(btScalar(5.0f)); btTransform startTransform; startTransform.setIdentity(); // forgot to add this line CVector vCamera = m_srtCamera.GetPosition(); startTransform.setOrigin(btVector3(vCamera.x, vCamera.y, vCamera.z)); m_msCamera = new CPhysicsMotionState(startTransform, &m_srtCamera); btScalar tMass(80.7f); bool isDynamic = (tMass != 0.f); btVector3 localInertia(0,0,0); if (isDynamic) cameraShape->calculateLocalInertia(tMass,localInertia); btRigidBody::btRigidBodyConstructionInfo rbInfo(tMass, m_msCamera, cameraShape, localInertia); m_rigidBody = new btRigidBody(rbInfo); m_rigidBody->setCollisionFlags(m_rigidBody->getCollisionFlags() | btCollisionObject::CF_KINEMATIC_OBJECT); m_rigidBody->setActivationState(DISABLE_DEACTIVATION); This is the code in Update() that runs each frame: CSRTTransform srtCamera = CCameraTask::GetPtr()->GetCamera(); Quaternion qRotate = srtCamera.m_qRotate; btQuaternion rot = btQuaternion(qRotate.x, qRotate.y, qRotate.z, qRotate.w); CVector vCamera = CCameraTask::GetPtr()->GetPosition(); btVector3 pos = btVector3(vCamera.x, vCamera.y, vCamera.z); CPhysicsMotionState* cameraMotionState = CCameraTask::GetPtr()->GetMotionState(); cameraMotionState->setKinematicPos(rot, pos);

  • Recent ImageMagick on CentOS 6.3

    - by organicveggie
    I'm having a terrible time trying to get a recent version of ImageMagick installed on a CentOS 6.3 x86_64 server. First, I downloaded the RPM from the ImageMagick site and tried to install it. That failed due to missing dependencies: error: Failed dependencies: libHalf.so.4()(64bit) is needed by ImageMagick-6.8.0-4.x86_64 libIex.so.4()(64bit) is needed by ImageMagick-6.8.0-4.x86_64 libIlmImf.so.4()(64bit) is needed by ImageMagick-6.8.0-4.x86_64 libImath.so.4()(64bit) is needed by ImageMagick-6.8.0-4.x86_64 libltdl.so.3()(64bit) is needed by ImageMagick-6.8.0-4.x86_64 I have libtool-ltdl installed, but that includes libltdl.so.7, not libltdl.so.4. I have a similar problem with libHalf, libIex, libIlmImf and libImath. Typically, you can install OpenEXR to get those dependencies. Unfortunately, CentOS 6.3 includes OpenEXR 1.6.1, which includes ilmbase-devel 1.0.1. And that release of ilmbase-devel includes newer versions of those dependencies: libHalf.so.6 libIex.so.6 libIlmImf.so.6 libImath.so.6 I next tried following the instructions for installing ImageMagick from source. No luck there either. I get a build error: RPM build errors: File not found by glob: /home/sean/rpmbuild/BUILDROOT/ImageMagick-6.8.0-4.x86_64/usr/lib64/ImageMagick-6.8.0/modules-Q16/coders/djvu.* I even re-ran configure to explicitly exclude djvu and I still get the same error. At this point, I'm pulling my hair out. What's the easiest way to get a relatively recent version of ImageMagick ( 6.7) installed on CentOS 6.3? Does someone offer RPMs with dependencies somewhere?

  • Error when starting .Net-Application from ThinApp-Application

    - by user50209
    one of our customers uses SAP through VMWare ThinApp. In SAP there is a button that launches an .Net application from a server. When starting the .Net-application directly, there is no error. If the user tries to start the application by clicking the button in the ThinApp-Application, it displays the following errors: Microsoft Visual C++ Runtime Library R6034 An application has made an attempt to load the C runtime library incorrectly. Please contact the application's support team for more information. After clicking "OK" it displays: Microsoft Visual C++ Runtime Library Runtime Error! R6030 - CRT not initialized So, does the customer have to install some components into his ThinApp (if yes, which?) to get things working? Regards, inno ----- [EDIT] ----- @Sean: It's installed the following way: The .exe of the .Net-Application is on a mapped drive on a server. All clients have the requirements installed (.Net-framework for example) and start the .exe from the mapped drive. The ThinApp-Application tries to start this application and throws the mentioned exceptions. AFAIK there are no entry points for this application configured. What I should also mention is: The .Net-Application crashes during execution. That means, we have a debug mode implemented that shows what the application is doing. The application shows what it's doing and after some steps it crashes. The interesting point is: It's a .Net-application, not a C++ Application.

  • Why not block ICMP?

    - by Agvorth
    I think I almost have my iptables setup complete on my CentOS 5.3 system. Here is my script... # Establish a clean slate iptables -P INPUT ACCEPT iptables -P FORWARD ACCEPT iptables -P OUTPUT ACCEPT iptables -F # Flush all rules iptables -X # Delete all chains # Disable routing. Drop packets if they reach the end of the chain. iptables -P FORWARD DROP # Drop all packets with a bad state iptables -A INPUT -m state --state INVALID -j DROP # Accept any packets that have something to do with ones we've sent on outbound iptables -A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT # Accept any packets coming or going on localhost (this can be very important) iptables -A INPUT -i lo -j ACCEPT # Accept ICMP iptables -A INPUT -p icmp -j ACCEPT # Allow ssh iptables -A INPUT -p tcp --dport 22 -j ACCEPT # Allow httpd iptables -A INPUT -p tcp --dport 80 -j ACCEPT # Allow SSL iptables -A INPUT -p tcp --dport 443 -j ACCEPT # Block all other traffic iptables -A INPUT -j DROP For context, this machine is a Virtual Private Server Web app host. In a previous question, Lee B said that I should "lock down ICMP a bit more." Why not just block it altogether? What would happen if I did that (what bad thing would happen)? If I need to not block ICMP, how could I go about locking it down more?

  • How can see what processes makes my server slow?

    - by Steven
    All my websites on my server are extremely slow or not loading at all. Even server admin (Plesk) will not load some times. There's been no changes to the sites for the last coupple of months. How can I see what processes is making my server slow? My environment looks like this: Server: VPS running Linux 2.8.x OS: Centos 5 Manage interface: Plesk 9.x Memmory: 1024MB CPU: 2.2GHz My websites run on PHP and MySQL. I finally managed to telnet (Putty + SSH) in to my server. Running top did not show any processes using more than max 2% CPU and none were using exesive memmory. I also got a friend to install a program that checks the core files, and all seemed fine. So I'm leaning towards network issues or some other server malfunction. But I'm not able to find out what can be wrong. Here are some answers to Sean Kimball: I don't run mail services on my server yet There are noe specific bandwidth peaks. Prefork looks like this <IfModule prefork.c> StartServers 8 MinSpareServers 5 MaxSpareServers 20 ServerLimit 256 MaxClients 256 MaxRequestsPerChild 4000 </IfModule> Not sure what you mean with DNS question. But I think it's up and running. There are no processes running wild Where can I find avarage load? Telnet is disabled and I have to log in using SSH :)

  • Custom ASP.Net MVC 2 ModelMetadataProvider for using custom view model attributes

    - by SeanMcAlinden
    There are a number of ways of implementing a pattern for using custom view model attributes, the following is similar to something I’m using at work which works pretty well. The classes I’m going to create are really simple: 1. Abstract base attribute 2. Custom ModelMetadata provider which will derive from the DataAnnotationsModelMetadataProvider   Base Attribute MetadataAttribute using System; using System.Web.Mvc; namespace Mvc2Templates.Attributes {     /// <summary>     /// Base class for custom MetadataAttributes.     /// </summary>     public abstract class MetadataAttribute : Attribute     {         /// <summary>         /// Method for processing custom attribute data.         /// </summary>         /// <param name="modelMetaData">A ModelMetaData instance.</param>         public abstract void Process(ModelMetadata modelMetaData);     } } As you can see, the class simple has one method – Process. Process accepts the ModelMetaData which will allow any derived custom attributes to set properties on the model meta data and add items to its AdditionalValues collection.   Custom Model Metadata Provider For a quick explanation of the Model Metadata and how it fits in to the MVC 2 framework, it is basically a set of properties that are usually set via attributes placed above properties on a view model, for example the ReadOnly and HiddenInput attributes. When EditorForModel, DisplayForModel or any of the other EditorFor/DisplayFor methods are called, the ModelMetadata information is used to determine how to display the properties. All of the information available within the model metadata is also available through ViewData.ModelMetadata. The following class derives from the DataAnnotationsModelMetadataProvider built into the mvc 2 framework. I’ve overridden the CreateMetadata method in order to process any custom attributes that may have been placed above a property in a view model.   CustomModelMetadataProvider using System; using System.Collections.Generic; using System.Linq; using System.Web.Mvc; using Mvc2Templates.Attributes; namespace Mvc2Templates.Providers {     public class CustomModelMetadataProvider : DataAnnotationsModelMetadataProvider     {         protected override ModelMetadata CreateMetadata(             IEnumerable<Attribute> attributes,             Type containerType,             Func<object> modelAccessor,             Type modelType,             string propertyName)         {             var modelMetadata = base.CreateMetadata(attributes, containerType, modelAccessor, modelType, propertyName);               attributes.OfType<MetadataAttribute>().ToList().ForEach(x => x.Process(modelMetadata));               return modelMetadata;         }     } } As you can see, once the model metadata is created through the base method, a check for any attributes deriving from our new abstract base attribute MetadataAttribute is made, the Process method is then called on any existing custom attributes with the model meta data for the property passed in.   Hooking it up The last thing you need to do to hook it up is set the new CustomModelMetadataProvider as the current ModelMetadataProvider, this is done within the Global.asax Application_Start method. Global.asax protected void Application_Start()         {             AreaRegistration.RegisterAllAreas();               RegisterRoutes(RouteTable.Routes);               ModelMetadataProviders.Current = new CustomModelMetadataProvider();         }   In my next post, I’m going to demonstrate a cool custom attribute that turns a textbox into an ajax driven AutoComplete text box. Hope this is useful. Kind Regards, Sean McAlinden.

  • Building a Mafia&hellip;TechFest Style

    - by David Hoerster
    It’s been a few months since I last blogged (not that I blog much to begin with), but things have been busy.  We all have a lot going on in our lives, but I’ve had one item that has taken up a surprising amount of time – Pittsburgh TechFest 2012.  After the event, I went through some minutes of the first meetings for TechFest, and I started to think about how it all came together.  I think what inspired me the most about TechFest was how people from various technical communities were able to come together and build and promote a common event.  As a result, I wanted to blog about this to show that people from different communities can work together to build something that benefits all communities.  (Hopefully I've got all my facts straight.)  TechFest started as an idea Eric Kepes and myself had when we were planning our next Pittsburgh Code Camp, probably in the summer of 2011.  Our Spring 2011 Code Camp was a little different because we had a great infusion of some folks from the Pittsburgh Agile group (especially with a few speakers from LeanDog).  The line-up was great, but we felt our audience wasn’t as broad as it should have been.  We thought it would be great to somehow attract other user groups around town and have a big, polyglot conference. We started contacting leaders from Pittsburgh’s various user groups.  Eric and I split up the ones that we knew about, and we just started making contacts.  Most of the people we started contacting never heard of us, nor we them.  But we all had one thing in common – we ran user groups who’s primary goal is educating our members to make them better at what they do. Amazingly, and I say this because I wasn’t sure what to expect, we started getting some interest from the various leaders.  One leader, Greg Akins, is, in my opinion, Pittsburgh’s poster boy for the polyglot programmer.  He’s helped us in the past with .NET Code Camps, is a Java developer (and leader in Pittsburgh’s Java User Group), works with Ruby and I’m sure a handful of other languages.  He helped make some e-introductions to other user group leaders, and the whole thing just started to snowball. Once we realized we had enough interest with the user group leaders, we decided to not have a Fall Code Camp and instead focus on this new entity. Flash-forward to October of 2011.  I set up a meeting, with the help of Jeremy Jarrell (Pittsburgh Agile leader) to hold a meeting with the leaders of many of Pittsburgh technical user groups.  We had representatives from 12 technical user groups (Python, JavaScript, Clojure, Ruby, PittAgile, jQuery, PHP, Perl, SQL, .NET, Java and PowerShell) – 14 people.  We likened it to a scene from a Godfather movie where the heads of all the families come together to make some deal.  As a result, the name “TechFest Mafia” was born and kind of stuck. Over the next 7 months or so, we had our starts and stops.  There were moments where I thought this event would not happen either because we wouldn’t have the right mix of topics (was I off there!), or enough people register (OK, I was wrong there, too!) or find an appropriate venue (hmm…wrong there, too) or find enough sponsors to help support the event (wow…not doing so well).  Overall, everything fell into place with a lot of hard work from Eric, Jen, Greg, Jeremy, Sean, Nicholas, Gina and probably a few others that I’m forgetting.  We also had a bit of luck, too.  But in the end, the passion that we had to put together an event that was really about making ourselves better at what we do really paid off. I’ve never been more excited about a project coming together than I have been with Pittsburgh TechFest 2012.  From the moment the first person arrived at the event to the final minutes of my closing remarks (where I almost lost my voice – I ended up being diagnosed with bronchitis the next day!), it was an awesome event.  I’m glad to have been part of bringing something like this to Pittsburgh…and I’m looking forward to Pittsburgh TechFest 2013.  See you there!

  • Oracle Fusion Procurement Designed for User Productivity

    - by Applications User Experience
    Sean Rice, Manager, Applications User Experience Oracle Fusion Procurement Design Goals In Oracle Fusion Procurement, we set out to create a streamlined user experience based on the way users do their jobs. Oracle has spent hundreds of hours with customers to get to the heart of what users need to do their jobs. By designing a procurement application around user needs, Oracle has crafted a user experience that puts the tools that people need at their fingertips. In Oracle Fusion Procurement, the user experience is designed to provide the user with information that will drive navigation rather than requiring the user to find information. One of our design goals for Oracle Fusion Procurement was to reduce the number of screens and clicks that a user must go through to complete frequently performed tasks. The requisition process in Oracle Fusion Procurement (Figure 1) illustrates how we have streamlined workflows. Oracle Fusion Self-Service Procurement brings together billing metrics, descriptions of the order, justification for the order, a breakdown of the components of the order, and the amount—all in one place. Previous generations of procurement software required the user to navigate to several different pages to gather all of this information. With Oracle Fusion, everything is presented on one page. The result is that users can complete their tasks in less time. The focus is on completing the work, not finding the work. Figure 1. Creating a requisition in Oracle Fusion Self-Service Procurement is a consumer-like shopping experience. Will Oracle Fusion Procurement Increase Productivity? To answer this question, Oracle sought to model how two experts working head to head—one in an existing enterprise application and another in Oracle Fusion Procurement—would perform the same task. We compared Oracle Fusion designs to corresponding existing applications using the keystroke-level modeling (KLM) method. This method is based on years of research at universities such as Carnegie Mellon and research labs like Xerox Palo Alto Research Center. The KLM method breaks tasks into a sequence of operations and uses standardized models to evaluate all of the physical and cognitive actions that a person must take to complete a task: what a user would have to click, how long each click would take (not only the physical action of the click or typing of a letter, but also how long someone would have to think about the page when taking the action), and user interface changes that result from the click. By applying standard time estimates for all of the operators in the task, an estimate of the overall task time is calculated. Task times from the model enable researchers to predict end-user productivity. For the study, we focused on modeling procurement business process task flows that were considered business or mission critical: high-frequency tasks and high-value tasks. The designs evaluated encompassed tasks that are currently performed by employees, professional buyers, suppliers, and sourcing professionals in advanced procurement applications. For each of these flows, we created detailed task scenarios that provided the context for each task, conducted task walk-throughs in both the Oracle Fusion design and the existing application, analyzed and documented the steps and actions required to complete each task, and applied standard time estimates to the operators in each task to estimate overall task completion times. The Results The KLM method predicted that the Oracle Fusion Procurement designs would result in productivity gains in each task, ranging from 13 percent to 38 percent, with an overall productivity gain of 22.5 percent. These performance gains can be attributed to a reduction in the number of clicks and screens needed to complete the tasks. For example, creating a requisition in Oracle Fusion Procurement takes a user through only two screens, while ordering the same item in a previous version requires six screens to complete the task. Modeling user productivity has resulted not only in advances in Oracle Fusion applications, but also in advances in other areas. We leveraged lessons learned from the KLM studies to establish products like Oracle E-Business Suite (EBS). New user experience features in EBS 12.1.3, such as navigational improvements to the main menu, a Google-type search using auto-suggest, embedded analytics, and an in-context list of values tool help to reduce clicks and improve efficiency. For more information about KLM, refer to the Measuring User Productivity blog.

  • Oracle at The Forrester Customer Intelligence and Marketing Leadership Forums

    - by Christie Flanagan
    The Forrester Customer Intelligence Forum and the Forrester Marketing Leadership Forums will soon be here.  This year’s events will be co-located on April 18-19 at the J.W. Marriott at the L.A. Live entertainment complex in downtown Los Angeles.  Last year’s Marketing Forum was quite memorable for me.  You see, while Forrester analysts and business marketers were busy mingling over at the Marriott, another marketing powerhouse was taking up residence a few feet away at The Staples Center.  That’s right folks. Lada Gaga was coming to town.  And, as I came to learn, it made perfect sense for Lady Gaga and her legions of fans to be sharing a small patch of downtown L.A. with marketing leaders from all over the world.  After all, whether you like Lady Gaga or not, what pop star in recent memory has done more to build herself into a brand and to create an engaging, social and interactive customer experience for her Little Monsters?  While Lady Gaga won’t be back in town for this year’s Forrester events, there are still plenty of compelling reasons to make the trip out to Los Angeles.   The theme for The Forrester Customer Intelligence and Marketing Leadership Forums this year is “From Cool To Critical: Creating Engagement In The Age Of The Customer” and will tackle the important questions about how marketers can survive and thrive in the age of the empowered customer: •    How can you assess consumer uptake of new innovations?•    How do you build deep customer knowledge to drive competitive advantage?•    How do you drive deep, personalized customer engagement?•    What is more valuable — eyeballs or engagement?•    How do business customers engage in new media types?•    How can you tie social data to corporate data?•    Who should lead the movement to customer obsession?•    How should you shift your planning and measurement approaches to accommodate more data and a higher signal-to-noise ratio?•    What role does technology play in customizing and synchronizing marketing efforts across channels?As a platinum sponsor of the event, there will be a numbers of ways to interact with Oracle while you’re attending the Forums.  Here are some of the highlights:Oracle Speaking SessionThursday, April 19, 9:15am – 9:55amMaximize Customer Engagement and Retention with Integrated Marketing & LoyaltyMelissa Boxer, Vice President, Oracle CRM Marketing & LoyaltyCustomers expect to interact with your company, brand and products in more ways than ever before.   New devices and channels, such as mobile, social and web, are creating radical shifts in the customer buying process and the ways your company can reach and communicate with existing and potential customers.
