  • Database – Beginning with Cloud Database As A Service

    - by Pinal Dave
    I love my weekend projects. Everybody does different activities in their weekend – like traveling, reading or just nothing. Every weekend I try to do something creative and different in the database world. The goal is I learn something new and if I enjoy my learning experience I share with the world. This weekend, I decided to explore Cloud Database As A Service – Morpheus. In my career I have managed many databases in the cloud and I have good experience in managing them. I should highlight that today’s applications use multiple databases from SQL for transactions and analytics, NoSQL for documents, In-Memory for caching to Indexing for search.  Provisioning and deploying these databases often require extensive expertise and time.  Often these databases are also not deployed on the same infrastructure and can create unnecessary latency between the application layer and the databases.  Not to mention the different quality of service based on the infrastructure and the service provider where they are deployed. Moreover, there are additional problems that I have experienced with traditional database setup when hosted in the cloud: Database provisioning & orchestration Slow speed due to hardware issues Poor Monitoring Tools High network latency Now if you have a great software and expert network engineer, you can continuously work on above problems and overcome them. However, not every organization have the luxury to have top notch experts in the field. Now above issues are related to infrastructure, but there are a few more problems which are related to software/application as well. Here are the top three things which can be problems if you do not have application expert: Replication and Clustering Simple provisioning of the hard drive space Automatic Sharding Well, Morpheus looks like a product build by experts who have faced similar situation in the past. The product pretty much addresses all the pain points of developers and database administrators. What is different about Morpheus is that it offers a variety of databases from MySQL, MongoDB, ElasticSearch to Reddis as a service.  Thus users can pick and chose any combination of these databases.  All of them can be provisioned in a matter of minutes with a simple and intuitive point and click user interface.  The Morpheus cloud is built on Solid State Drives (SSD) and is designed for high-speed database transactions.  In addition it offers a direct link to Amazon Web Services to minimize latency between the application layer and the databases. Here are the few steps on how one can get started with Morpheus. Follow along with me.  First go to http://www.gomorpheus.com and register for a new and free account. Step 1: Signup It is very simple to signup for Morpheus. Step 2: Select your database   I use MySQL for my daily routine, so I have selected MySQL. Upon clicking on the big red button to add Instance, it prompted a dialogue of creating a new instance.   Step 3: Create User Now we just have to create a user in our portal which we will use to connect to a database hosted at Morpheus. Click on your database instance and it will bring you to User Screen. Over here you will notice once again a big red button to create a new user. I created a user with my first name.   Step 4: Configure your MySQL client I used MySQL workbench and connected to MySQL instance, which I had created with an IP address and user.   That’s it! You are connecting to MySQL instance. Now you can create your objects just like you would create on your local box. You will have all the features of the Morpheus when you are working with your database. Dashboard While working with Morpheus, I was most impressed with its dashboard. In future blog posts, I will write more about this feature.  Also with Morpheus you use the same process for provisioning and connecting with other databases: MongoDB, ElasticSearch and Reddis.

  • Big Data – Beginning Big Data Series Next Month in 21 Parts

    - by Pinal Dave
    Big Data is the next big thing. There was a time when we used to talk in terms of MB and GB of the data. However, the industry is changing and we are now moving to a conversation where we discuss about data in Petabyte, Exabyte and Zettabyte. It seems that the world is now talking about increased Volume of the data. In simple world we all think that Big Data is nothing but plenty of volume. In reality Big Data is much more than just a huge volume of the data. When talking about the data we need to understand about variety and volume along with volume. Though Big data look like a simple concept, it is extremely complex subject when we attempt to start learning the same. My Journey I have recently presented on Big Data in quite a few organizations and I have received quite a few questions during this roadshow event. I have collected all the questions which I have received and decided to post about them on the blog. In the month of October 2013, on every weekday we will be learning something new about Big Data. Every day I will share a concept/question and in the same blog post we will learn the answer of the same. Big Data – Plenty of Questions I received quite a few questions during my road trip. Here are few of the questions. I want to learn Big Data – where should I start? Do I need to know SQL to learn Big Data? What is Hadoop? There are so many organizations talking about Big Data, and every one has a different approach. How to start with big Data? Do I need to know Java to learn about Big Data? What is different between various NoSQL languages. I will attempt to answer most of the questions during the month long series in the next month. Big Data – Big Subject Big Data is a very big subject and I no way claim that I will be covering every single big data concept in this series. However, I promise that I will be indeed sharing lots of basic concepts which are revolving around Big Data. We will discuss from fundamentals about Big Data and continue further learning about it. I will attempt to cover the concept so simple that many of you might have wondered about it but afraid to ask. Your Role! During this series next month, I need your one help. Please keep on posting questions you might have related to big data as blog post comments and on Facebook Page. I will monitor them closely and will try to answer them as well during this series. Now make sure that you do not miss any single blog post in this series as every blog post will be linked to each other. You can subscribe to my feed or like my Facebook page or subscribe via email (by entering email in the blog post).

  • Java in Flux: Utopia or Deuteranopia?

    - by Tori Wieldt
    What a difference a year makes, indeed. Steve Harris, Senior VP, App Server Dev, Oracle and Adam Messinger, VP, Fusion Middleware Group, Oracle presented an informative keynote at the TheServerSide Java Symposium today. With a title "Java in Flux: Utopia or Deuteranopia?" you know things are going to be interesting (see Aeon Flux if you don't get the title reference).What a YearThey started with a little background, explaining that the reactions to Oracle's acquisition of Sun (and therefore Java) one year ago varied greatly, from "Freak Out!" to "Don't Panic." From the Oracle perspective, being the steward of and key contributor to Java requires a lot of sausage making.  They admitted to Oracle's fair share of Homer Simpson-esque "D'oh" moments in the past year, which was complicated by Oracle's communication style.   "Oracle has a tradition has a saying a few things and sticking by then, in contrast to Sun who was much more open," Adam explained. "We laid out the Java roadmap and are executing on it, and we hope that speaks to our commitment."Java SEAdam talked about having a long term perspective on the Java language (20+ years), letting ideas mature in more experimental languages, then bringing them into Java. Current priorities include: JVM convergence (getting the best features of JRockit into Hotspot); support of parallel/multi-core programming, and of course, all the improvements in JDK7. The JDK7 Developer Preview is underway (please download now and report bugs!). The Oracle development team is also working on Lambda and modularity (Jigsaw) for SE 8. Less certain, but also under discussion are improvements for Java SE 9. Adam is thinking of it as a "back to basics" release. He mentioned reworking JNI, improving data integration and improved device support.Java EE To provide context about Java EE, Steve said Java EE was great at getting businesses on the internet. The success of Java EE resulted in an incredible expansion of the middleware marketplace for developers and vendors.  But with success, came more. Java EE kept piling on capabilities, but that created excess baggage.  Doing simple things was no longer so simple. That's where Java community is so valuable: "When Java EE was too complex and heavyweight, many people were happy to tell us what we were doing wrong and popularize solutions," Steve explained. Because of that feedback, the Java EE teams focused on making things simple again: POJOs and annotations, and leveraging changes in Java SE.  Steve said that "innovation doesn't happen in expert groups, it happens on the ground where developers are solving problems," and platform stewards need to pay attention and take advantage of changes that are taking place.Enter the Cloud "Developers are restless, they want cloud functionality from their own IT dept" Steve explained. With the cloud, the scope of problem has expanded to include the data center itself, with multiple tenants. To move forward, existing APIs in Java EE need to be updated to be tenant-aware, service-enabled, and EE needs to support various styles of deployment. The goal is to get all that done in Java EE 8.Adam questioned Steve about timing and schedule. "Yes, the schedule is aggressive, but it'll work" Steve said. Then Adam asked about modularization. If Java SE 8 comes out at the end of 2012, when can Java EE deliver modularization? Steve suggested that key stakeholders can come with up some pre-SE 8 agreement on how to expose the metadata about modules. He then alluded to Mark Reinhold and John Duimovich's keynote at EclipseCON next week. Stay tuned.Evil Master PlanIn conclusion, Adam finally admitted to Oracle's Evil Master Plan: 1) Invest in and improve Java SE and EE 2) Collaborate with the community 3) Broaden the marketplace for Java development. Bwaaaaaaaaahahaha! <rubs hands together>Key LinksJDK7 Developer Preview  http://jdk7.java.net/preview/Oracle Technology Network http://www.oracle.com/technetwork/java/index.htmlTheServerSide Java Symposium  http://javasymposium.techtarget.com/"Utopia or Deuteranopia?" http://en.wikipedia.org/wiki/Aeon_Flux

  • How to create (via installer script) a task that will install my bash script so it runs on DE startup?

    - by MountainX
    I've been reading for the last couple hours about Upstart, .xinitrc, .xsessions, rc.local, /etc/init.d/, /etc/xdg/autostart, @reboot in crontab and so many other things that I'm totally confused! Here is my bash script. It should start/run after the desktop environment is started and it should continue to run at all times until logout/shutdown. It should start again on reboot. Any time the DE is running, it should run. #!/bin/bash while true; do if [[ -s ~/.updateNotification.txt ]]; then read MSG < ~/.updateNotification.txt kdialog --title 'The software has been updated' --msgbox "$MSG" cat /dev/null > ~/.updateNotification.txt fi sleep 3600 done exit 0 I know zero about using Upstart, but I understand that Upstart is one way to handle this. I'll consider other approaches but most of the things I've been reading about are too complex for me. Furthermore, I can't figure out which approach will meet my requirements (which I'll detail below). There are two steps in my question: How to automatically start the script above, as described above. How to "install" that Upstart task via a bash script (i.e., my "installer"). I assume (or hope) that step 2 is almost trivial once I understand step 1. I have to support all flavors of Ubuntu desktops. Therefore, the kdialog call above will be replaced. I'm considering easybashgui for this. (Or I could use zenity on gnome DE's.) My requirements are: The setup process (installation) must be done via a bash script. I cannot use the GUI method described in the Ubuntu doc AddingProgramToSessionStartup, for example. I must be able to script/automate the setup (installing) process using bash. Currently, it is as simple as having the bash installer script copy the above script into /home/$USER/.kde/Autostart/ The setup process must be universal across Ubuntu derivatives including Unity and KDE and gnome desktops. The same setup script (installer) should run on Linux Mint, Kubuntu, Xbuntu (basically any flavor of Ubuntu and major derivatives such as Linux Mint). For example, we cannot continue to put a script file in /home/$USER/.kde/Autostart/ because that exists only on KDE. The above script should work for each of the limited flavors we use. Hence our interest in using easybashgui instead of kdialog or zenity. See below. The installed monitoring script should only be started after the desktop is started since it will display a GUI message to the user if the update is found. The monitoring script (above) should run without root privileges, of course. But the installer (bash script) can be run as root. I'm not a real developer or a sysadmin. This is a part time volunteer thing for me, so it needs to be easy/simple. I can write bash scripts and I can program a little, but I know nothing about Upstart or systemd, for example. And, unfortunately, my job doesn't give me time to become an expert on init systems or much of anything else related to development and sysadmin. So I have to stick with simple solutions. The easybashgui version of the script might look like this: #!/bin/bash source easybashgui while true; do if [[ -s ~/.updateNotification.txt ]]; then read MSG < ~/.updateNotification.txt message "$MSG" cat /dev/null > ~/.updateNotification.txt fi sleep 3600 done exit 0

  • Where to start with game development?

    - by steven_desu
    I asked this earlier in this thread at stackoverflow.com. One of the early comments redirected me here to gamedev.stackexchange.com, so I'm reposting here. Searching for related questions I found a number of very specific questions, but I'm afraid the specifics have proved fruitless for me and after 4 hours on Google I'm no closer than I started, so I felt reaching out to a community might be in order. First, my goal: I've never made a game before, although I've muddled over the possibility several times. I decided to finally sit down and start learning how to code games, use game engines, etc. All so that one day (hopefully soon) I'll be able to make functional (albeit simple) games. I can start adding complexity later, for now I'd be glad to have a keyboard-controlled camera moving in a 3D world with no interaction beyond that. My background: I've worked in SEVERAL programming languages ranging from PHP to C++ to Java to ASM. I'm not afraid of any challenges that come with learning the new syntax or limitations inherent in a new language. All of my past programming experience, however, has been strictly non-graphical and usually with little or extremely simple interaction during execution. I've created extensive and brilliant algorithms for solving logical and mathematical problems as well as graphing problems. However in every case input was either defined in a file, passed form an HTML form, or typed into the console. Real-time interaction with the user is something with which I have no experience. My question: Where should I start in trying to make games? Better yet- where should I start in trying to create a keyboard-navigable 3D environment? In searching online I've found several resources linking to game engines, graphics engines, and physics engines. Here's a brief summary of my experiences with a few engines I tried: Unreal SDK: The tutorial videos assume that you already have in-depth knowledge of 3D modeling, graphics engines, animations, etc. The "Getting Started" page offers no formal explanation of game development but jumps into how Unreal can streamline processes it assumes you're already familiar with. After downloading the SDK and launching it to see if the tools were as intuitive as they claimed, I was greeted with about 60 buttons and a blank void for my 3D modeling. Clicking on "add volume" (to attempt to add a basic cube) I was met with a menu of 30 options. Panicking, I closed the editor. Crystal Space: The website seemed rather informative, explaining that Crystal Space was just for graphics and the companion software, CEL, provided entity logic for making games. A demo game was provided, which was built using "CELStart", their simple tool for people with no knowledge of game programming. I launched the game to see what I might look forward to creating. It froze several times, the menus were buggy, there were thousands of graphical glitches, enemies didn't respond to damage, and when I closed the game it locked up. Gave up on that engine. IrrLicht: The tutorial assumes I have Visual Studio 6.0 (I have Visual Studio 2010). Following their instructions I was unable to properly import the library into Visual Studio and unable to call any of the functions that they kept using. Manually copying header files, class files, and DLLs into my project's folder - the project failed to properly compile. Clearly I'm not off to a good start and I'm going in circles. Can someone point me in the right direction? Should I start by downloading a program like Blender and learning 3D modeling, or should I be learning how to use a graphics engine? Should I look for an all-inclusive game engine, or is it better to try and code my own game logic? If anyone has actually made their own games, I would prefer to hear how they got their start. Also- taking classes at my school is not an option. Nothing is offered.

  • Code Contracts: validating arrays and collections

    - by DigiMortal
    Validating collections before using them is very common task when we use built-in generic types for our collections. In this posting I will show you how to validate collections using code contracts. It is cool how much awful looking code you can avoid using code contracts. Failing code Let’s suppose we have method that calculates sum of all invoices in collection. We have class Invoice and one of properties it has is Sum. I don’t introduce here any complex calculations on invoices because we have another problem to solve in this topic. Here is our code. public static decimal CalculateTotal(IList<Invoice> invoices) {     var sum = invoices.Sum(p => p.Sum);     return sum; } This method is very simple but it fails when invoices list contains at least one null. Of course, we can test if invoice is null but having nulls in lists like this is not good idea – it opens green way for different coding bugs in system. Our goal is to react to bugs ASAP at the nearest place they occur. There is one more way how to make our method fail. It happens when invoices is null. I thing it is also one common bugs during development and it even happens in production environments under some conditions that are usually hardly met. Now let’s protect our little calculation method with code contracts. We need two contracts: invoices cannot be null invoices cannot contain any nulls Our first contract is easy but how to write the second one? Solution: Contract.ForAll Preconditions in code are checked using Contract.Ensures method. This method takes boolean value as argument that sais if contract holds or not. There is also method Contract.ForAll that takes collection and predicate that must hold for that collection. Nice thing is ForAll returns boolean. So, we have very simple solution. public static decimal CalculateTotal(IList<Invoice> invoices) {     Contract.Requires(invoices != null);     Contract.Requires(Contract.ForAll<Invoice>(invoices, p => p != null));       var sum = invoices.Sum(p => p.Sum);     return sum; } And here are some lines of code you can use to test the contracts quickly. var invoices = new List<Invoice>(); invoices.Add(new Invoice()); invoices.Add(null); invoices.Add(new Invoice()); //CalculateTotal(null); CalculateTotal(invoices); If your code is covered with unit tests then I suggest you to write tests to check that these contracts hold for every code run. Conclusion Although it seemed at first place that checking all elements in collection may end up with for-loops that does not look so nice we were able to solve our problem nicely. ForAll method of contract class offered us simple mechanism to check collections and it does it smoothly the code-contracts-way. P.S. I suggest you also read devlicio.us blog posting Validating Collections with Code Contracts by Derik Whittaker.

The Real Architects of Los Angeles - OTN Architect Day - Oct 25 No gossip. No drama. No hair pulling. Just a full day of technical sessions and peer interaction focused on using Oracle technologies in today's cloud and SOA architectures. The event is free, but seating is limited, so register now. Thursday October 25, 2012. 8:00 a.m. – 5:00 p.m. Sofitel Los Angeles, 8555 Beverly Boulevard, Los Angeles, CA 90048. Oracle Fusion Middleware Security: Attaching OWSM policies to JRF-based web services clients "OWSM (Oracle Web Services Manager) is Oracle's recommended method for securing SOAP web services," says Oracle Fusion Middleware A-Team member Andre Correa. "It provides agents that encapsulate the necessary logic to interact with the underlying software stack on both service and client sides. Such agents have their behavior driven by policies. OWSM ships with a bunch of policies that are adequate to most common real world scenarios." His detailed post shows how to make it happen. Oracle 11gR2 RAC on Software Defined Network (SDN) (OpenvSwitch, Floodlight, Beacon) | Gilbert Stan "The SDN [software defined network] idea is to separate the control plane and the data plane in networking and to virtualize networking the same way we have virtualized servers," explains Gil Standen. "This is an idea whose time has come because VMs and vmotion have created all kinds of problems with how to tell networking equipment that a VM has moved and to preserve connectivity to VPN end points, preserve IP, etc." H/T to Oracle ACE Director Tim Hall for the recommendation. Process Oracle OER Events using a simple Web Service | Bob Webster Bob Webster's post "provides an example of a simple web service that processes Oracle Enterprise Repository (OER) Events. The service receives events from OER and utilizes the OER REX API to implement simple OER automations for selected event types." Understanding Oracle BI 11g Security vs Legacy Oracle BI 10g | Christian Screen "After conducting a large amount of Oracle BI 10g to Oracle BI 11g upgrades and after writing the Oracle BI 11g book,"says Oracle ACE Christian Screen, "I still continually get asked one of the most basic questions regarding security in Oracle BI 11g; How does it compare to Oracle BI 10g? The trail of questions typically goes on to what are the differences? And, how do we leverage our current Oracle BI 10g security table schema in Oracle BI 11g?" OIM-OAM-OAAM integration using TAP – Request Flow you must understand!! | Atul Kumar Atul Kumar's post addresses "key points and request flow that you must understand" when integrating three Oracle Identity Management product Oracle Identity Management, Oracle Access Management, and Oracle Adaptive Access Manager.

  • Using Teleriks new LINQ implementation to connect to MySQL

    Last week Telerik released a new LINQ implementation that is simple to use and produces domain models very fast. Built on top of the enterprise grade OpenAccess ORM, you can connect to any database that OpenAccess can connect to such as: SQL Server, MySQL, Oracle, SQL Azure, VistaDB, etc. Today I will show you how to build a domain model using MySQL as your back end. To get started, you have to download MySQL 5.x and the MySQL Workbench and also, as my colleague Alexander Filipov at Telerik reminded me, make sure you install the MySQL .NET Connector, which is available here.  I like to use Northwind, ok it gives me the warm and fuzzies, so I ran a script to produce Northwind on my MySQL server. There are many ways you can get Northwind on your MySQL database, here is a helpful blog to get your started. I also manipulated the first record to indicate that I am in MySQL and gave a look via the MySQL Workbench. Ok, time to build our model! Start up the Domain Model wizard by right clicking on the project in Visual Studio (I have a Web project) and select Add|New Item and choose Telerik OpenAccess Domain Model from the new item list. When the wizard comes up, choose MySQL as your back end and enter in the name of your saved MySQL connection. If you dont have a saved MySQL connection set up in Visual Studio, click on New Connection and enter in the proper connection information. *Note, this is where you need to have the MySQL .NET connector installed. After you set your connection to the MySQL database server, you have to choose which tables to include in your model. Just for fun, I will choose all of them. Give your model a name, like NorthwindEntities and click finish. That is it. Now lets consume the model with ASP .net. I created a simple page that also has a GridView on it. On my page load I wrote this code, by now it should look very familiar, a simple LINQ query filtering customers by country (Germany) and binding the results to the grid.  1: protected void Page_Load(object sender, EventArgs e) 2: { 3: if (!IsPostBack) 4: { 5: //a reference to the data context 6: NorthwindEntities dat = new NorthwindEntities(); 7: //LINQ Statement 8: var result = from c in dat.Customers 9: where c.Country == "Germany" 10: select c; 11: //Databinding to the Gridview 12: GridView1.DataSource = result; 13: GridView1.DataBind(); 14: } 15: } .csharpcode, .csharpcode pre{ font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/}.csharpcode pre { margin: 0em; }.csharpcode .rem { color: #008000; }.csharpcode .kwrd { color: #0000ff; }.csharpcode .str { color: #006080; }.csharpcode .op { color: #0000c0; }.csharpcode .preproc { color: #cc6633; }.csharpcode .asp { background-color: #ffff00; }.csharpcode .html { color: #800000; }.csharpcode .attr { color: #ff0000; }.csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em;}.csharpcode .lnum { color: #606060; } F5 produces the following. Tomorrow Ill show how to take the same model and create an Astoria/OData data feed.

  • Deploying an SSL Application to Windows Azure &ndash; The Dark Secret

    - by ToStringTheory
    When working on an application that had been in production for some time, but was about to have a shopping cart added to it, the necessity for SSL certificates came up.  When ordering the certificates through the vendor, the certificate signing request (CSR) was generated through the providers (http://register.com) web interface, and within a day, we had our certificate. At first, I thought that the certification process would be the hard part…  Little did I know that my fun was just beginning… The Problem I’ll be honest, I had never really secured a site before with SSL.  This was a learning experience for me in the first place, but little did I know that I would be learning more than the simple procedure.  I understood a bit about SSL already, the mechanisms in how it works – the secure handshake, CA’s, chains, etc…  What I didn’t realize was the importance of the CSR in the whole process.  Apparently, when the CSR is created, a public key is created at the same time, as well as a private key that is stored locally on the PC that generated the request.  When the certificate comes back and you import it back into IIS (assuming you used IIS to generate the CSR), all of the information is combined together and the SSL certificate is added into your store. Since at the time the certificate had been ordered for our site, the selection to use the online interface to generate the CSR was chosen, the certificate came back to us in 5 separate files: A root certificate – (*.crt file) An intermediate certifcate – (*.crt file) Another intermediate certificate – (*.crt file) The SSL certificate for our site – (*.crt file) The private key for our certificate – (*.key file) Well, in case you don’t know much about Windows Azure and SSL certificates, the first thing you should learn is that certificates can only be uploaded to Azure if they are in a PFX package – securable by a password.  Also, in the case of our SSL certificate, you need to include the Private Key with the file.  As you can see, we didn’t have a PFX file to upload. If you don’t get the simple PFX from your hosting provider, but rather the multiple files, you will soon find out that the process has turned from something that should be simple – to one that borders on a circle of hell… Probably between the fifth and seventh somewhere… The Solution The solution is to take the files that make up the certificates chain and key, and combine them into a file that can be imported into your local computers store, as well as uploaded to Windows Azure.  I can not take the credit for this information, as I simply researched a while before finding out how to do this. Download the OpenSSL for Windows toolkit (Win32 OpenSSL v1.0.1c) Install the OpenSSL for Windows toolkit Download and move all of your certificate files to an easily accessible location (you'll be pointing to them in the command prompt, so I put them in a subdirectory of the OpenSSL installation) Open a command prompt Navigate to the folder where you installed OpenSSL Run the following command: openssl pkcs12 -export –out {outcert.pfx} –inkey {keyfile.key}      –in {sslcert.crt} –certfile {ca1.crt} –certfile (ca2.crt) From this command, you will get a file, outcert.pfx, with the sum total of your ssl certificate (sslcert.crt), private key {keyfile.key}, and as many CA/chain files as you need {ca1.crt, ca2.crt}. Taking this file, you can then import it into your own IIS in one operation, instead of importing each certificate individually.  You can also upload the PFX to Azure, and once you add the SSL certificate links to the cloud project in Visual Studio, your good to go! Conclusion When I first looked around for a solution to this problem, there were not many places online that had the information that I was looking for.  While what I ended up having to do may seem obvious, it isn’t for everyone, and I hope that this can at least help one developer out there solve the problem without hours of work!

  • Requesting feedback on my OO design

    - by Prog
    I'm working on an application that creates music by itself. I'm seeking feedback for my OO design so far. This question will focus on one part of the program. The application produces Tune objects, that are the final musical products. Tune is an abstract class with an abstract method play. It has two subclasses: SimpleTune and StructuredTune. SimpleTune owns a Melody and a Progression (chord sequence). It's play implementation plays these two objects simultaneously. StructuredTune owns two Tune instances. It's own play plays the two Tunes one after the other according to a pattern (currently only ABAB). Melody is an abstract class with an abstract play method. It has two subclasses: SimpleMelody and StructuredMelody. SimpleMelody is composed of an array of notes. Invoking play on it plays these notes one after the other. StructuredMelody is composed of an array of Melody objects. Invoking play on it plays these Melodyies one after the other. I think you're starting to see the pattern. Progression is also an abstract class with a play method and two subclasses: SimpleProgression and StructuredProgression, each composed differently and played differently. SimpleProgression owns an array of chords and plays them sequentially. StructuredProgression owns an array of Progressions and it's play implementation plays them sequentially. Every class has a corresponding Generator class. Tune, Melody and Progression are matched with corresponding abstract TuneGenerator, MelodyGenerator and ProgressionGenerator classes, each with an abstract generate method. For example MelodyGenerator defines an abstract Melody generate method. Each of the generators has two subclasses, Simple and Structured. So for example MelodyGenerator has a subclasses SimpleMelodyGenerator, with an implementation of generate that returns a SimpleMelody. (It's important to note that the generate methods encapsulate complex algorithms. They are more than mere factory method. For example SimpleProgressionGenerator.generate() implements an algorithm to compose a series of Chord objects, which are used to instantiate the returned SimpleProgression). Every Structured generator uses another generator internally. It is a Simple generator be default, but in special cases may be a Structured generator. Parts of this design are meant to allow the end-user through the GUI to choose what kind of music is to be created. For example the user can choose between a "simple tune" (SimpleTuneGenerator) and a "full tune" (StructuredTuneGenerator). Other parts of the system aren't subject to direct user-control. What do you think of this design from an OOD perspective? What potential problems do you see with this design? Please share with me your criticism, I'm here to learn. Apart from this, a more specific question: the "every class has a corresponding Generator class" part feels very wrong. However I'm not sure how I could design this differently and achieve the same flexibility. Any ideas?

  • A developer&rsquo;s WBS &ndash; 3 factors of 5

    - by johndoucette
    As a development manager, I have requested work breakdown structures (WBS) many times from the dev leads. Everyone has their own approach and why it takes sometimes days to get this simple list is often frustrating. Here is a simple way to get that elusive WBS done in 30 minutes and have 125 items in your list – well, 126. The WBS is made up of parent-child entities representing the overall outcome of the project. At the bottom of the hierarchical list should be the task item that a developer would perform in support of the branch in the list or WBS. Because I work with different dev leads on every project, I always ask the “what time value would you like to see at the lowest task in order to assign it to a developer and ensure it gets done within the timeframe”. I am particular to a task being 8 hours. Some like 8 to 24 hours. Stay away from tasks defaulting to 1 week. The task becomes way to vague and hard to manage completeness, especially on short budgets. As a developer, your focus is identifying the tasks you to accomplish in order to deliver the product. As a project manager, you will take the developer's WBS and add all the “other stuff” like quality testing, meetings, documentation, transition to maintenance, etc… Start your exercise with the name of the product you are delivering as a result of the project. You should be able to represent what you are building and deploying with one to three words. Example; XYZ Public Website Middleware BizTalk Application The reason you start with that single identifier is to always see the list as the product. It helps during each of the next three passes. Now, choose 5 tasks which in their entirety represent the product you will be delivering and add them to list under the product name you created earlier; Public Website     Security     Sites     Infrastructure     Publishing     Creative Continue this concept of seeing the list as the complete picture and decompose it one more level. You should have 25 items. Public Website     Security         Authentication         Login Control         Administration         DRM         Workflow     Sites         Masterpages         Page Layouts         Web Parts (RIA, Multimedia)         Content Types         Structures     Infrastructure         ...     Publishing         ...     Creative         ... And one more time for a total of 125 items. The top item makes the list 126. Public Website     Security         Authentication             Install (AD/ADAM/LDAP/SQL)             Configuration             Management             Web App Configuration             Implement Provider         Login Control             Login Form             Login/Logoff             pw change             pw recover/forgot             email verification         Administration             ...         DRM             ...         Workflow             ...     Sites         Masterpages         Page Layouts         Web Parts (RIA, Multimedia)         Content Types         Structures     Infrastructure         ...     Publishing         ...     Creative         ... The next step is to make sure the task at the bottom of every branch represents the “time value” you planned for the project. You can add more to the WBS and of course if you can’t find 5 items, 4 is fine. If a task can be done in a fraction of the time value you determined for the project, try to roll it up into a larger task. In the task actions (later when the iteration is being planned), decompose the details back to the simple tasks. Now, go estimate!

  • Consumer Oriented Search In Oracle Endeca Information Discovery – Part 1

    - by Bob Zurek
    Information Discovery, a core capability of Oracle Endeca Information Discovery, enables business users to rapidly search, discover and navigate through a wide variety of big data including structured, unstructured and semi-structured data. One of the key capabilities, among many, that differentiate our solution from others in the Information Discovery market is our deep support for search across this growing amount of varied big data. Our method and approach is very different than classic simple keyword search that is found in may information discovery solutions. In this first part of a series on the topic of search, I will walk you through many of the key capabilities that go beyond the simple search box that you might experience in products where search was clearly an afterthought or attempt to catch up to our core capabilities in this area. Lets explore. The core data management solution of Oracle Endeca Information Discovery is the Endeca Server, a hybrid search-analytical database that his highly scalable and column-oriented in nature. We will talk in more technical detail about the capabilities of the Endeca Server in future blog posts as this post is intended to give you a feel for the deep search capabilities that are an integral part of the Endeca Server. The Endeca Server provides best-of-breed search features aw well as a new class of features that are the first to be designed around the requirement to bridge structured, semi-structured and unstructured big data. Some of the key features of search include type a heads, automatic alphanumeric spell corrections, positional search, Booleans, wildcarding, natural language, and category search and query classification dialogs. This is just a subset of the advanced search capabilities found in Oracle Endeca Information Discovery. Search is an important feature that makes it possible for business users to explore on the diverse data sets the Endeca Server can hold at any one time. The search capabilities in the Endeca server differ from other Information Discovery products with simple “search boxes” in the following ways: The Endeca Server Supports Exploratory Search.  Enterprise data frequently requires the user to explore content through an ad hoc dialog, with guidance that helps them succeed. This has implications for how to design search features. Traditional search doesn’t assume a dialog, and so it uses relevance ranking to get its best guess to the top of the results list. It calculates many relevance factors for each query, like word frequency, distance, and meaning, and then reduces those many factors to a single score based on a proprietary “black box” formula. But how can a business users, searching, act on the information that the document is say only 38.1% relevant? In contrast, exploratory search gives users the opportunity to clarify what is relevant to them through refinements and summaries. This approach has received consumer endorsement through popular ecommerce sites where guided navigation across a broad range of products has helped consumers better discover choices that meet their, sometimes undetermined requirements. This same model exists in Oracle Endeca Information Discovery. In fact, the Endeca Server powers many of the most popular e-commerce sites in the world. The Endeca Server Supports Cascading Relevance. Traditional approaches of search reduce many relevance weights to a single score. This means that if a result with a good title match gets a similar score to one with an exact phrase match, they’ll appear next to each other in a list. But a user can’t deduce from their score why each got it’s ranking, even though that information could be valuable. Oracle Endeca Information Discovery takes a different approach. The Endeca Server stratifies results by a primary relevance strategy, and then breaks ties within a strata by ordering them with a secondary strategy, and so on. Application managers get the explicit means to compose these strategies based on their knowledge of their own domain. This approach gives both business users and managers a deterministic way to set and understand relevance. Now that you have an understanding of two of the core search capabilities in Oracle Endeca Information Discovery, our next blog post on this topic will discuss more advanced features including set search, second-order relevance as well as an understanding of faceted search mechanisms that include queries and filters.

  • Four Easy Ways to Save a Rocky CRM Relationship

    - by Divya Malik
     Today, I am pleased to introduce our guest blogger Luke Christianson. Luke is  an Application Sales rep based out of Minneapolis, MN.  You can find him on LinkedIn and follow him on Twitter. In any relationship, sooner or later, the excitement fades away.  The honeymoon period gives way to the old routines you had, before you committed to each other and you eventually begin doing things apart from one another.  I’m not talking about a marriage…  Well, I guess I am.Commitment to a CRM tool and building a deep and lasting relationship is not much different than the basics of a traditional love story.  After your controlled CRM pilot program, and maybe the National Sales Meeting where you couldn’t escape those three wonderful letters, CRM, you will soon find that if you haven’t designed an environment where it’s going to enable your reps to make more money, the relationship is doomed.   . If you’re currently in a dysfunctional CRM relationship, here are 4 simple tips to re-engaging users and getting that spark back. Shadow a Sales Rep:   Chances are you can find out exactly what is preventing your sales reps from using the application by simply watching how they go about their day.  Sales reps are driven by money, not by additional administrative duties.  Your system needs to be setup so that they can get the information they need quickly, facilitate making key updates and run their business out of one easy-to-use application.  Increase your sales team’s productivity by 5% automatically:    Cancel the weekly forecast calls with your reps and require them update their opportunities in CRM.  Something else that I’ve seen work extremely well, is when you do Monthly or Quarterly reviews, do not let your sales reps bring anything into the room with them; no spreadsheets, notebooks, or computers.  Everything they need to tell you should be able to be put into CRM and fully accessible by the Sales Manager at any time.  Tool time:      Make sure the tools that you have selected meet both your short-term goals and your long term goals.   You need tools that can adapt like your business does.  You probably can’t wait two months for an update to a picklist value or for the addition of a simple workflow rule.  Do you feel the tools that are in place can create the experience you want for your users? and finally, if all else fails... Keep It Simple, Stupid:     Do you really need to require 15 fields to create an Opportunity?  Do you need to clutter the interface with different reports that don’t add daily value?  Most CRM systems on the market today are flexible enough today that your admin could clean up most of the unnecessary interface ‘noise’ in a few hours.  If they're not, see #3. Every strong relationship can be tedious at times, you’ll fight and eventually make amends, you may even threaten to upgrade to a newer model…  But be patient and think about what you want to achieve and you’ll find a partner for life.

  • Find Knowledge Quickly

    - by Get Proactive Customer Adoption Team
    Untitled Document Get to relevant knowledge on the Oracle products you use in a few quick steps! Customers tell us that the volume of search results returned can make it difficult to find the information they need, especially when similar Oracle products exist. These simple tips show you how to filter, browse, search, and refine your results to get relevant answers faster. Filter first: PowerView is your best friend Powerview is an often ignored feature of My Oracle Support that enables you to control the information displayed on the Dashboard, the Knowledge tab and regions, and the Service Request tab based on one or more parameters. You can define a PowerView to limit information based on product, product line, support ID, platform, hostname, system name and others. Using PowerView allows you to restrict: Your search results to the filters you have set The product list when selecting your products in Search & Browse and when creating service requests   The PowerView menu is at the top of My Oracle Support, near the title You turn PowerView on by clicking PowerView is Off, which is a button. When PowerView is On, and filters are active, clicking the button again will toggle Powerview off. Click the arrow to the right to create new filters, edit filters, remove a filter, or choose from the list of previously created filters. You can create a PowerView in 3 simple steps! Turn PowerView on and select New from the PowerView menu. Select your filter from the Select Filter Type dropdown list and make selections from the other two menus. Hint: While there are many filter options, selecting your product line or your list of products will provide you with an effective filter. Click the plus sign (+) to add more filters. Click the minus sign (-) to remove a filter. Click Create to save and activated the filter(s) You’ll notice that PowerView is On displays along with the active filters. For more information about the PowerView capabilities, click the Learn more about PowerView… menu item or view a short video. Browse & Refine: Access the Best Match Fast For Your Product and Task In the Knowledge Browse region of the Knowledge or Dashboard tabs, pick your product, pick your task, select a version, if applicable. A best match document – a collection of knowledge articles and resources specific to your selections - may display, offering you a one-stop shop. The best match document, called an “information center,” is an aggregate of dynamically updated links to information pertinent to the product, task, and version (if applicable) you chose. These documents are refreshed every 24 hours to ensure that you have the most current information at your fingertips. Note: Not all products have “information centers.” If no information center appears as a best match, click Search to see a list of search results. From the information center, you can access topics from a product overview to security information, as shown in the left menu. Just want to search? That’s easy too! Again, pick your product, pick your task, select a version, if applicable, enter a keyword term, and click Search. Hint: In this example, you’ll notice that PowerView is on and set to PeopleSoft Enterprise. When PowerView is on and you select a product from the Knowledge Base product list, the listed products are limited to the active PowerView filter. (Products you’ve previously picked are also listed at the top of the dropdown list.) Your search results are displayed based on the parameters you entered. It’s that simple!

  • Would this be a good web application architecture?

    - by Gustav Bertram
    My problem Our MVC based framework does not allow us to cache only part of our output. Ideally we want to cahce static and semi-static bits, and run dynamic bits. In addition, we need to consider data caching that reacts to database changes. My idea The concept I came up with was to represent a page as a tree of XML fragment objects. (I say XML, but I mean XHTML). Some of the fragments are dynamic, and can pull their data directly from models or other sources, but most of the fragments are static scaffolding. If a subtree of fragments is completely static, then I imagine that they could unfold into pure XML that would then be cached as the text representation of their parent element. This process would ideally continue until we are left with a root element that contains all of the static XML, and has a couple of dynamic XML fragments that are resolved and attached to the relevant nodes of the XML tree just before the page is displayed. In addition to separating content into dynamic and static fragments, some fragments could be dynamic and cached. A simple expiry time which propagates up through the XML fragment tree would indicate that a specific fragment should periodically be refreshed. A newspaper section or front page does not need to be updated each second. Minutes or sometimes even longer is sufficient. Other fragments would be dynamic and uncached. Typically too many articles are viewed for them to be cached - the cache would overflow. Some individual articles may be cached if they are extremely popular. Functional notes The folding mechanism could be to be smart enough to judge when it would be more profitable to fold a dynamic cached fragment and propagate the expiry date to the parent fragment, or to keep it separate and simple attach to the XML tree when resolving the page. If some dynamic cached fragments are associated to database objects through mechanisms like a globally unique content id, then changes to the database could trigger changes to the output cache. If fragments store the identifiers of parent fragments, then they could trigger a refolding process that would then include the updated data. A set of pure XML with an ordered array of fragment objects (that each store the identifying information of the node to which they should be attached), can be resolved in a fairly simple way by walking the XML tree, and merging the data from the fragments. Because it is not necessary to parse and construct the entire tree in memory before attaching nodes, processing should be fairly fast. The identifiers of each fragment would be a combination of relevant identity data and the type of fragment object. Cached parent fragments would contain references to these identifiers, in order to then either pull them from the fragment cache, or to run their code. The controller's responsibility is reduced to making changes to the database, and telling the root XML fragment object to render itself. The Question My question has two parts: Is this a good design? Are there any obvious flaws I'm missing? Has somebody else thought of this before? References? Is there an existing alternative that I should consider? A cool templating engine maybe?

  • Creating a Corporate Data Hub

    - by BuckWoody
    The Windows Azure Marketplace has a rich assortment of data and software offerings for you to use – a type of Software as a Service (SaaS) for IT workers, not necessarily for end-users. Among those offerings is the “Data Hub” – a  codename for a project that ironically actually does what the codename says. In many of our organizations, we have multiple data quality issues. Finding data is one problem, but finding it just once is often a bigger problem. Lots of departments and even individuals have stored the same data more than once, and in some cases, made changes to one of the copies. It’s difficult to know which location or version of the data is authoritative. Then there’s the problem of accessing the data. It’s fairly straightforward to publish a database, share or other location internally to store the data. But then you have to figure out who owns it, how it is controlled, and pass out the various connection strings to those who want to use it. And then you need to figure out how to let folks access the internal data externally – bringing up all kinds of security issues. Finally, in many cases our user community wants us to combine data from the internally sources with external data, bringing up the security, strings, and exploration features up all over again. Enter the Data Hub. This is an online offering, where you assign an administrator and data stewards. You import the data into the service, and it’s available to you - and only you and your organization if you wish. The basic steps for this service are to set up the portal for your company, assign administrators and permissions, and then you assign data areas and import data into them. From there you make them discoverable, and then you have multiple options that you or your users can access that data. You’re then able, if you wish, to combine that data with other data in one location. So how does all that work? What about security? Is it really that easy? And can you really move the data definition off to the Subject Matter Experts (SME’s) that know the particular data stack better than the IT team does? Well, nothing good is easy – but using the Data Hub is actually pretty simple. I’ll give you a link in a moment where you can sign up and try this yourself. Once you sign up, you assign an administrator. From there you’ll create data areas, and then use a simple interface to bring the data in. All of this is done in a portal interface – nothing to install, configure, update or manage. After the data is entered in, and you’ve assigned meta-data to describe it, your users have multiple options to access it. They can simply use the portal – which actually has powerful visualizations you can use on any platform, even mobile phones or tablets.     Your users can also hit the data with Excel – which gives them ultimate flexibility for display, all while using an authoritative, single reference for the data. Since the service is online, they can do this wherever they are – given the proper authentication and permissions. You can also hit the service with simple API calls, like this one from C#: http://msdn.microsoft.com/en-us/library/hh921924  You can make HTTP calls instead of code, and the data can even be exposed as an OData Feed. As you can see, there are a lot of options. You can check out the offering here: http://www.microsoft.com/en-us/sqlazurelabs/labs/data-hub.aspx and you can read the documentation here: http://msdn.microsoft.com/en-us/library/hh921938

  • SharePoint Content and Site Editing Tips

    - by Bil Simser
    A few content management and site editing tips for power users on this bacon flavoured unicorn morning. The theme here is keep it clean!Write "friendly" email addressesRemember it's human beings reading your content. So seeing something like "If you have questions please send an email to [email protected]" breaks up the readiblity. Instead just do the simple steps of writing the content in plain English and going back, highlighting the name and insert a link (note: you might have to prefix the link with mailto:[email protected]). It makes for a friendlier looking page and hides the ugliness that are sometimes in email addresses.Use friendly column and list namesThis is a big pet peeve of mine. When you first create a column or list with spaces the internal name is changed. The display name might be "My Amazing List of Animals with Large Testicles" but the internal (and link) name becomes "My_x00x20_Amazing_x00x20_List_x00x20_of_x00x20_Animals_x00x20_with_x00x20_Large_x00x20_Testicles". What's worse is if you create a publishing page named "This Website is Fueled By a Dolphin's Spleen". Not only is it incorrect grammar, but the apostrophe wreaks havoc on both the internal name for the list (with lots of crazy hex codes) as well as the hyperlink (where everything is uuencoded). Instead create the list with a distinct and compact name then go back and change it to whatever you want. The end result is a better formed name that you can both script and access in code easier.Keep your Views CleanWhen you add a column to a list or create a new list the default is to add it to the default view. Do everyone a favour and don't check this box! The default view of a list should be something similar to the Title field and nothing else. Keep it clean. If you want to set a defalt view that's different, go back and create one with all the fields and filtering and sorting columns you want and set it as default. It's a good idea to keep the original AllItems.aspx (note the lack of space in the filename!) easy and unfiltered. It's also a good idea to keep your column count down in views. Don't let every column be added by default and don't add every column just because you can. Create separate views for distinct responsibilities and try to keep the number of columns down to a single screen to prevent horizontal scrolling.Simple NavigationThe Quick Launch is a great tool for navigating around your site but don't use the default of adding all lists to it. Uncheck that box and keep navigation simple. Create custom groupings that make sense so if you don't have a site with "Documents and Lists" but "Reports and Notices" makes more sense then do it. Also hide internal lists from the Quick Launch. For example, if most users don't need to see all the lookup tables you might have on a site don't show them. You can use audience filtering on the Quick Launch if you want to hide admin items from non-admin users so consider that as an option.Enjoy!

  • Creating a Corporate Data Hub

    - by BuckWoody
    The Windows Azure Marketplace has a rich assortment of data and software offerings for you to use – a type of Software as a Service (SaaS) for IT workers, not necessarily for end-users. Among those offerings is the “Data Hub” – a  codename for a project that ironically actually does what the codename says. In many of our organizations, we have multiple data quality issues. Finding data is one problem, but finding it just once is often a bigger problem. Lots of departments and even individuals have stored the same data more than once, and in some cases, made changes to one of the copies. It’s difficult to know which location or version of the data is authoritative. Then there’s the problem of accessing the data. It’s fairly straightforward to publish a database, share or other location internally to store the data. But then you have to figure out who owns it, how it is controlled, and pass out the various connection strings to those who want to use it. And then you need to figure out how to let folks access the internal data externally – bringing up all kinds of security issues. Finally, in many cases our user community wants us to combine data from the internally sources with external data, bringing up the security, strings, and exploration features up all over again. Enter the Data Hub. This is an online offering, where you assign an administrator and data stewards. You import the data into the service, and it’s available to you - and only you and your organization if you wish. The basic steps for this service are to set up the portal for your company, assign administrators and permissions, and then you assign data areas and import data into them. From there you make them discoverable, and then you have multiple options that you or your users can access that data. You’re then able, if you wish, to combine that data with other data in one location. So how does all that work? What about security? Is it really that easy? And can you really move the data definition off to the Subject Matter Experts (SME’s) that know the particular data stack better than the IT team does?

  • Can someone explain the true landscape of Rails vs PHP deployment, particularly within the context of Reseller-based web hosting (e.g., Hostgator)?

    - by rcd
    Currently, I have a reseller account with the company HostGator. I design websites, which up until now have occasionally been wrapped in Wordpress CMSs and the like (PHP applications). I then sell hosting (of the site I've designed) to the client, which is pretty simple, in that I can simply click a button and add a new shared hosting account/site with whatever settings I want. Furthermore, I then utilize WHMCS to automate billing and account management. It's a nice package and pretty simple. I pay something like $25 a month, and can sell a hundred accounts under this (because my clients bandwidth requirements are low). Now I am finding the need to develop more customized applications, including a minimalist CMS and several proprietary things. I soon anticipate developing these apps for clients as well. Thus, I've spent the past few months learning Rails, and it's coming along well now. The thing that has nagged at me all along, though, is the deployment issue. I can't wrap my brain around it. It seems like all of the popular options (Heroku, etc) have nice automation with git and are set up in the "Rails Way". I get that (sort of). But it's terribly expensive... a single dyno, a helper, and the cheapest database (which they say is mainly suitable for testing) that isn't limited to 5MB runs $51. This is for ONE app!!! Throw in a "production" DB and you're over $200. This is like... the same prices as getting a server somewhere, right? Meanwhile, going back to what I guess is a "traditional" hosting environment with Hostgator, their server only has Ruby 1.8.7 and Rails 2.3.5... No Rails 3. AND, no Passenger (not that I really understand the difference in CGI or mod_rails or whatever, but they say Passenger is the simplest). So I'm to understand that if I build an app in Rails 3, it won't run at all on this host? But damn, I already have these accounts under my reseller account there, all running static html and/or PHP stuff, right? So what now? How do I get all of this under one simple (and affordable) roof? Forgive my ignorance, but I just don't get it. Managing a VPS is cool and all, but entails learning server admin stuff and security... And it's expensive. I get that a shared and/or reseller "server-based" (forgive the terminology) may be inadequate for large-scale apps that use a lot of bandwidth... But what about for those of us who are building real (but small and low bandwidth) apps (with Rails) and who want to deploy them simply, cheaply, using the same conceptual approach as PHP? Even after learning all of this Ruby and Rails stuff for months, I'm questioning whether it's worth it when it comes to deployment. I want to build a small app, upload it to my home directory on a shared server account, and just make it run. Why should that be so hard? Am I just choosing the wrong language/framework? Forgive my ignorance in the subject; these questions are not rhetorical; just trying to learn here. So: 1) I'd appreciate if someone could give me a good rundown of how to understand deployment in Rails vs. PHP. 2) I'd appreciate if someone could address my issue with running a hosting/web business around reseller hosting (Hostgator) while also being able to host Rails apps. Can it be done? And how can a company like Hostgator completely ignore what's current in Rails/Ruby? Thanks.

  • Disabling the right-click sub menu using JQuery

    - by nikolaosk
    Recently I needed to disable the right-click contextual menu in an HTML page for a very simple HTML application I was creating for a friend.This is going to be a short post where I will demonstrate how to disable the right-click contextual menu.I will use the very popular JQuery Library. Please download the library (minified version) from http://jquery.com/downloadPlease find here all my posts regarding JQuery.In this hands-on example I will be using Expression Web 4.0.This application is not a free application. You can use any HTML editor you like.You can use Visual Studio 2012 Express edition. You can download it here. I am going to create a very simple HTML 5 page with some text and an image. The HTML markup for the page follows. <!DOCTYPE html><html lang="en">  <head>    <title>HTML 5, CSS3 and JQuery</title>        <meta http-equiv="Content-Type" content="text/html;charset=utf-8" >    <link rel="stylesheet" type="text/css" href="style.css">     <script type="text/javascript" src="jquery-1.8.2.min.js">        </script><script type="text/javascript"> (function ($) { $(document).bind('contextmenu', function () { return false;}); })(jQuery); </script>       </head>  <body>      <div id="header">      <h1>Learn cutting edge technologies</h1>      <h2>HTML 5, JQuery, CSS3</h2>    </div>      <figure>  <img src="html5.png" alt="HTML 5"></figure>        <div id="main">          <h2>HTML 5</h2>                        <article>          <p>            HTML5 is the latest version of HTML and XHTML. The HTML standard defines a single language that can be written in HTML and XML. It attempts to solve issues found in previous iterations of HTML and addresses the needs of Web Applications, an area previously not adequately covered by HTML.          </p>          </article>      </div>             </body>  </html> This is the JQuery code, I use (function ($) { $(document).bind('contextmenu', function () { return false;}); })(jQuery); I simply disable/cancel the contextmenu event.When I load the simple page on the browser and I right-click the context menu does not appear.Hope it helps!!!

  • ASP.NET how to use __doPostBack from Custom JavaScript with Master/Content Pages

    - by harrije
    In a simple aspx page I can have a custom JavaScript function postback as described in http://www.xefteri.com/articles/show.cfm?id=18 The simple page uses a linkbutton: <asp:LinkButton id="CreateFile" runat="server" onclick="CreateFile_Click" /> with code behind that has the VB subroutine: Sub CreateFile_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) and a Javascript custom function that does: __doPostBack('CreateFile',''); When I move the code to a content page with a corresponding master page the simple example no longer works. I'm aware that server control IDs are changed in the generated HTML when a master page is involved, and I'm using the correct IDs in the Javascript. As an example, for the LinkButton ID I use '<%=CreateFile.ClientID%' for the Javascript in the generated HTML. Never the less, I still can't figure out how to get postbacks from the Javascript when master pages are involved. More accurately, with a master page in the mix the code won't even compile but results in: 'CreateFile_Click' is not a member of 'ASP.testmaster_aspx' If I remove onclick="CreateFile_Click" from the LinkButton markup it compiles but does not work. Similary if onclick is removed from the simpler version without a master page it does not work either, as expected. Any input on how to get postback from a custom Javascript function when using master pages would be much appreciated.

  • What is the equivalent of memset in C#?

    - by Jedidja
    I need to fill a byte[] with a single non-zero value. How can I do this in C# without looping through each byte in the array? Update: The comments seem to have split this into two questions - Is there a Framework method to fill a byte[] that might be akin to memset What is the most efficient way to do it when we are dealing with a very large array? I totally agree that using a simple loop works just fine, as Eric and others have pointed out. The point of the question was to see if I could learn something new about C# :) I think Juliet's method for a Parallel operation should be even faster than a simple loop. Benchmarks: Thanks to Mikael Svenson: http://techmikael.blogspot.com/2009/12/filling-array-with-default-value.html It turns out the simple for loop is the way to go unless you want to use unsafe code. Apologies for not being clearer in my original post. Eric and Mark are both correct in their comments; need to have more focused questions for sure. Thanks for everyone's suggestions and responses.
