  • 10 Best Programming Podcast 2010 Edition

    - by mbcrump
    This list is in no particular order. Just the 10 best programming podcast that I have found so far. Stack Overflow Podcast -  Jeff Atwood (of codinghorror.com) and Joel Spolsky (of joelonsoftware.com) discuss the development of their new programming community, StackOverflow.com. [This Podcast hasn’t been updated in a while, but its always great to hear more from Jeff Atwood] Hanselminutes - Hanselminutes is a weekly audio talk show with noted web developer and technologist Scott Hanselman and hosted by Carl Franklin. Scott discusses utilities and tools, gives practical how-to advice, and discusses ASP.NET or Windows issues and workarounds. [This Podcast has recently started talking about random topics like diabetes, plane travel and geek relationship tips.  I am not sure if Scott is trying to move to a more mainstream audience or not] Herding Code - A weekly discussion featuring K. Scott Allen (odetocode.com), Kevin Dente, Scott Koon (lazycoder.com), and Jon Galloway. [Great all all-around podcast that I would recommend to all] Deep Fried Bytes - Deep Fried Bytes is an audio talk show with a Southern flavor hosted by technologists and developers Keith Elder and Chris Woodruff. The show discusses a wide range of topics including application development, operating systems and technology in general. Anything is fair game if it plugs into the wall or takes a battery. [This is one that just keeps getting better] Dot Net Rocks - .NET Rocks! is an Internet Audio Talk Show for Microsoft .NET Developers. [One of the first and usually very high quality content] Connected Show - Connected Show Podcast! A podcast covering new Microsoft technology for the developer community. The show is hosted by Dmitry Lyalin and Peter Laudati. [This and Polymorphic are one of my favorite podcast – Dmitry is a great host and would recommend this to all] Polymorphic Podcast - Object oriented development, architecture and best practices in .NET [Craig is a ASP.NET MVP and a great presenter. His podcast is great and it could only be better if he recorded it more often] ASP.NET Podcast - Wallace B. (Wally) McClure presents interviews and short technical talks on .NET Technologies. [Has great information on ASP.NET of course as well as iPhone Dev] Ruby on Rails Podcast - News and interviews about the Ruby language and the Rails website framework. [Even though I am not a Ruby programmer, I’ve found this podcast very interesting] Software Engineering Radio - Software Engineering Radio is a podcast targeted at the professional software developer. The goal is to be a lasting educational resource, not a newscast. Every ten days, a new episode is published that covers all topics software engineering. Episodes are either tutorials on a specific topic, or an interview with a well-known character from the software engineering world. All SE Radio episodes are original content ? we do not record conferences or talks given in other venues. Each episode comprises two speakers to ensure a lively listening experience. SE Radio is an independent and non-commercial organization. [Another excellent podcast – I would recommend any programmer add this to his/her drive home] If I have missed something, please feel free to email me and it might make the 2011 list. =)

  • Building a Data Mart with Pentaho Data Integration Video Review by Diethard Steiner, Packt Publishing

Indeed, a video watcher should be familiar with its concepts as the Star Schema, Slowly Changing Dimension types, etc. so I suggest prior to watching this course to consider skimming through the Data Warehouse concepts (if unfamiliar) or even better, read the excellent Ralph’s The Data Warehouse Tooolkit. By the way, the author expands beyond using Pentaho along to MySQL and MonetDB which is a real icing on the cake! Indeed, I even suggest the name of the course should be ‘Building a Data Warehouse with Pentaho’. To successfully complete the course one needs to know some Linux (Ubuntu used in the course), the VI editor and the Bash command shell, but it seems that similar requirements would also apply to the Weindows OS. Additionally, knowing some basic SQL would not hurt. As I had said, MonetDB is used in this course several times which seems to be not anymore complex than say MySQL, but based on what I read is very well suited for fast querying big volumes of data thanks to having a columnstore (vertical data storage). I don’t see what else can be a barrier, the material is very digestible. On this note, I must add that the author does not cover how to acquire the software, so here is what I found may help: Pentaho: the free Community Edition must be more than anyone needs to learn it. Or even go into a POC. MonetDB can be downloaded (exists for both, Linux and Windows) from http://goo.gl/FYxMy0 (just see the appropriate link on the left). The author seems to be using Eclipse to run SQL code, one can get it from http://goo.gl/5CcuN. To create, or edit database entities and/or schema otherwise one can use a universal tool called SQuirreL, get it from http://squirrel-sql.sourceforge.net.   Next, I must confess Diethard is very knowledgeable in what he does and beyond. However, there will be some accent heard to the user of the course especially if one’s mother tongue language is English, but it I got over it in a few chapters. I liked the rate at which the material is being presented, it makes me feel I paid for every second Eventually, my impressions are: Pentaho is an awesome ETL offering, it is worth learning it very much (I am an ETL fan and a heavy user of SSIS) MonetDB is nice, it tickles my fancy to know it more Data Warehousing, despite all the BigData tool offerings (Hive, Scoop, Pig on Hadoop), using the traditional tools still rocks Chapters 2 to 6 were the most fun to me with chapter 8 being the most difficult.   In terms of closing, I highly recommend this video to anyone who needs to grasp Pentaho concepts quick, likewise, the course is very well suited for any developer on a “supposed to be done yesterday” type of a project. It is for a beginner to intermediate level ETL/DW developer. But one would need to learn more on Data Warehousing and Pentaho, for such I recommend the 5 star Pentaho Data Integration 4 Cookbook. Enjoy it! Disclaimer: I received this video from the publisher for the purpose of a public review.

  • Using Managed Beans with your ADF Mobile Client Applications

    - by [email protected]
    Did you know it's easy to extend your ADF Mobile Client application with a Managed Bean just like it is with an ADF web application?  Here's how: Using the New Gallery (File -> New), create a new Java class.  This class should extend oracle.adfnmc.el.utils.BeanResolver.         Add this java class as a managed bean: Go to your task flow, select the Overview tab at the bottom and go to the Managed Bean section.  Add an entry and name your new Managed Bean and point to the java class you just created.        Add your custom methods and properties to your java class   Since reflection is not supported in the J2ME version on some platforms (BlackBerry), you need to provide dispatch code if you want to invoke/access any of your methods/properties from EL.  Here's a sample:  MyBeanClass.java    Use Expression Language (EL) to access your properties and invoke your methods on your MCX pages.  Here's an sample:     <?xml version="1.0" encoding="UTF-8" ?><amc:view xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"          xmlns:amc="http://xmlns.oracle.com/jdev/amc">  <amc:form id="form0">    <amc:menuControl refId="menu0"/>    <amc:panelGroupLayout id="panelGroupLayout1" width="100%">      <amc:panelGroupLayout id="panelGroupLayout2" layout="horizontal"                            width="100%">        <amc:image id="image1" source="logo_sm.png"/>        <amc:outputText value="Home" id="outputText1" verticalAlign="center"                        fontSize="20" fontWeight="bold"                        foregroundColor="#ff0000"/>      </amc:panelGroupLayout>      <amc:commandLink text="#{MyBean.property1}" id="commandLink1"                       actionListener="#{MyBean.doFoo}"                       foregroundColor="#0000ff" action="patientlist"/>    </amc:panelGroupLayout>  </amc:form>  <amc:menu type="main" id="menu0">    <amc:menuGroup id="menuGroup1">      <amc:commandMenuItem id="commandMenuItem1" action="exit" label="Exit"                           index="1" weight="0"/>    </amc:menuGroup>  </amc:menu></amc:view>

  • Employee Info Starter Kit: Project Mission

    - by Mohammad Ashraful Alam
    Employee Info Starter Kit is an open source ASP.NET project template that is intended to address different types of real world challenges faced by web application developers when performing common CRUD operations. Using a single database table ‘Employee’, it illustrates how to utilize Microsoft ASP.NET 4.0, Entity Framework 4.0 and Visual Studio 2010 effectively in that context. Employee Info Starter Kit is highly influenced by the concept ‘Pareto Principle’ or 80-20 rule. where it is targeted to enable a web developer to gain 80% productivity with 20% of effort with respect to learning curve and production. User Stories The user end functionalities of this starter kit are pretty simple and straight forward that are focused in to perform CRUD operation on employee records as described below. Creating a new employee record Read existing employee record Update an existing employee record Delete existing employee records Key Technology Areas ASP.NET 4.0 Entity Framework 4.0 T-4 Template Visual Studio 2010 Architectural Objective There is no universal architecture which can be considered as the best for all sorts of applications around the world. Based on requirements, constraints, environment, application architecture can differ from one to another. Trade-off factors are one of the important considerations while deciding a particular architectural solution. Employee Info Starter Kit is highly influenced by the concept ‘Pareto Principle’ or 80-20 rule, where it is targeted to enable a web developer to gain 80% productivity with 20% of effort with respect to learning curve and production. “Productivity” as the architectural objective typically also includes other trade-off factors as well as, such as testability, flexibility, performance etc. Fortunately Microsoft .NET Framework 4.0 and Visual Studio 2010 includes lots of great features that have been implemented cleverly in this project to reduce these trade-off factors in the minimum level. Why Employee Info Starter Kit is Not a Framework? Application frameworks are really great for productivity, some of which are really unavoidable in this modern age. However relying too many frameworks may overkill a project, as frameworks are typically designed to serve wide range of different usage and are less customizable or editable. On the other hand having implementation patterns can be useful for developers, as it enables them to adjust application on demand. Employee Info Starter Kit provides hundreds of “connected” snippets and implementation patterns to demonstrate problem solutions in actual production environment. It also includes Visual Studio T-4 templates that generate thousands lines of data access and business logic layer repetitive codes in literally few seconds on the fly, which are fully mock testable due to language support for partial methods and latest support for mock testing in Entity Framework. Why Employee Info Starter Kit is Different than Other Open-source Web Applications? Software development is one of the rapid growing industries around the globe, where the technology is being updated very frequently to adapt greater challenges over time. There are literally thousands of community web sites, blogs and forums that are dedicated to provide support to adapt new technologies. While some are really great to enable learning new technologies quickly, in most cases they are either too “simple and brief” to be used in real world scenarios or too “complex and detailed” which are typically focused to achieve a product goal (such as CMS, e-Commerce etc) from "end user" perspective and have a long duration learning curve with respect to the corresponding technology. Employee Info Starter Kit, as a web project, is basically "developer" oriented which actually considers a hybrid approach as “simple and detailed”, where a simple domain has been considered to intentionally illustrate most of the architectural and implementation challenges faced by web application developers so that anyone can dive into deep into the corresponding new technology or concept quickly. Roadmap Since its first release by 2008 in MSDN Code Gallery, Employee Info Starter Kit gained a huge popularity in ASP.NET community and had 1, 50,000+ downloads afterwards. Being encouraged with this great response, we have a strong commitment for the community to provide support for it with respect to latest technologies continuously. Currently hosted in Codeplex, this community driven project is planned to have a wide range of individual editions, each of which will be focused on a selected application architecture, framework or platform, such as ASP.NET Webform, ASP.NET Dynamic Data, ASP.NET MVC, jQuery Ajax (RIA), Silverlight (RIA), Azure Service Platform (Cloud), Visual Studio Automated Test etc. See here for full list of current and future editions.

  • Fill a Flash Drive with Portable Software using Lupo PenSuite

    - by Asian Angel
    A flash drive full of portable software is helpful to have along wherever you go. The Lupo PenSuite lets you choose from three different versions to get the best fit for your everyday needs. Note: If running the full version you will need a 512 MB USB flash drive or larger. Using Lupo PenSuite The one window to watch for during the setup process is where you have the opportunity to add a specific language pack if needed. Outside of that all that you need to do is sit back and wait for the suite to be extracted. Note: Extraction times will vary based on version and extraction location. Here we browsed to our flash drive to extract it to… Once the setup process is complete locate and double click the Lupo_PenSuite.exe file. This one time window will present you the opportunity to start using the suite immediately, or go directly into the options. When the suite is active you will have a new system tray icon that operates as a start menu button. At the bottom you can monitor the remaining room on your flash drive, and use the close button to exit the suite (may display as a power button based on menu theme). A quick look at the set up inside the suite. There is a pre-configured area for organizing and storing your personal files. Prefer a classic style menu? Just select for it in the options (various tab) and enjoy a smaller streamlined look. Note: You can also change the theme for the regular menu and add a user pic. The suite provides access to your portable software and online sites. You get to enjoy the best of both as shown in the following examples. Websites will open using the suite’s portable Firefox install. VLC is ready to play your downloaded videos. The suite also has some very nice photo editing programs added in. Installing Additional Apps If one of your favorite programs is not included in the suite version, it only takes a few minutes to add it in. Go to the Additional Apps webpage, download the app(s), and extract them onto your hard-drive. Note: Link for additional apps webpage provided below. Add the extracted app(s) to the MyApps folder in the suite’s folder hierarchy. Click on ASuite in the suite’s start menu. Drag and drop the portable app’s exe file into the MyApps section in the ASuite window. Your new software’s shortcut should display as shown here. Close this window when finished. Checking the suite’s start menu will show your new software ready to be used. Conclusion If you need a good portable software collection to carry with you on a flash drive then Lupo PenSuite is definitely worth taking a look at. We tested Lupo PenSuite on XP, Vista, and Windows 7 and it works great on all three. Another popular choice is PortableApps and you can check out our Review of that too they are essentially the same thing, each is just packaged differently. Links Download Lupo PenSuite (Full, Lite, & Zero versions) *Download links approximately one-third down the page. Download Additional Apps for Lupo PenSuite Download Additional Skins for Lupo PenSuite Start Menu View Video Tutorials *Has tutorial for easy updating of entire suite.

    Windows Live Writer is a great tool for writing and publishing posts to your blog, but its spell check unfortunately doesn’t include many common tech words.  Here’s how you can easily edit your custom dictionary and add your favorite words. Customize Live Writer’s Dictionary Adding an individual word to the Windows Live Writer dictionary works as you would expect.  Right-click on a word and select Add to dictionary. And changing the default spell check settings is easy too.  In the menu, click Tools, then Options, and select the Spelling tab in this dialog.  Here you can choose your dictionary language and turn on/off real-time spell checking and other settings. But there’s no obvious way to edit your custom dictionary.  Editing the custom dictionary directly is nice if you accidently add a misspelled word to your dictionary and want to remove it, or if you want to add a lot of words to the dictionary at once. Live Writer actually stores your custom dictionary entries in a plain text file located in your appdata folder.  It is saved as User.dic in the C:\Users\user_name\AppData\Roaming\Windows Live Writer\Dictionaries folder.  The easiest way to open the custom dictionary is to enter the following in the Run box or the address bar of an Explorer window: %appdata%\Windows Live Writer\Dictionaries\User.dic   This will open the User.dic file in your default text editor.  Add any new words to the custom dictionary on separate lines, and delete any misspelled words you accidently added to the dictionary.   Microsoft Office Word also stores its custom dictionary in a plain text file.  If you already have lots of custom words in it and want to import them into Live Writer, enter the following in the Run command or Explorer’s address bar to open Word’s custom dictionary.  Then copy the words, and past them into your Live Writer custom dictionary file. %AppData%\Microsoft\UProof\Custom.dic Don’t forget to save the changes when you’re done.  Note that the changes to the dictionary may not show up in Live Writer’s spell check until you restart the program.  If it’s currently running, save any posts you’re working on, exit, and then reopen, and all of your new words should be in the dictionary. Conclusion Whether you use Live Writer daily in your job or occasionally post an update to a personal blog, adding your own custom words to the dictionary can save you a lot of time and frustration in editing.  Plus, if you’ve accidently added a misspelled word to the dictionary, this is a great way to undo your mistake and make sure your spelling is up to par!

  • Big Data – Operational Databases Supporting Big Data – Key-Value Pair Databases and Document Databases – Day 13 of 21

    - by Pinal Dave
    In yesterday’s blog post we learned the importance of the Relational Database and NoSQL database in the Big Data Story. In this article we will understand the role of Key-Value Pair Databases and Document Databases Supporting Big Data Story. Now we will see a few of the examples of the operational databases. Relational Databases (Yesterday’s post) NoSQL Databases (Yesterday’s post) Key-Value Pair Databases (This post) Document Databases (This post) Columnar Databases (Tomorrow’s post) Graph Databases (Tomorrow’s post) Spatial Databases (Tomorrow’s post) Key Value Pair Databases Key Value Pair Databases are also known as KVP databases. A key is a field name and attribute, an identifier. The content of that field is its value, the data that is being identified and stored. They have a very simple implementation of NoSQL database concepts. They do not have schema hence they are very flexible as well as scalable. The disadvantages of Key Value Pair (KVP) database are that they do not follow ACID (Atomicity, Consistency, Isolation, Durability) properties. Additionally, it will require data architects to plan for data placement, replication as well as high availability. In KVP databases the data is stored as strings. Here is a simple example of how Key Value Database will look like: Key Value Name Pinal Dave Color Blue Twitter @pinaldave Name Nupur Dave Movie The Hero As the number of users grow in Key Value Pair databases it starts getting difficult to manage the entire database. As there is no specific schema or rules associated with the database, there are chances that database grows exponentially as well. It is very crucial to select the right Key Value Pair Database which offers an additional set of tools to manage the data and provides finer control over various business aspects of the same. Riak Rick is one of the most popular Key Value Database. It is known for its scalability and performance in high volume and velocity database. Additionally, it implements a mechanism for collection key and values which further helps to build manageable system. We will further discuss Riak in future blog posts. Key Value Databases are a good choice for social media, communities, caching layers for connecting other databases. In simpler words, whenever we required flexibility of the data storage keeping scalability in mind – KVP databases are good options to consider. Document Database There are two different kinds of document databases. 1) Full document Content (web pages, word docs etc) and 2) Storing Document Components for storage. The second types of the document database we are talking about over here. They use Javascript Object Notation (JSON) and Binary JSON for the structure of the documents. JSON is very easy to understand language and it is very easy to write for applications. There are two major structures of JSON used for Document Database – 1) Name Value Pairs and 2) Ordered List. MongoDB and CouchDB are two of the most popular Open Source NonRelational Document Database. MongoDB MongoDB databases are called collections. Each collection is build of documents and each document is composed of fields. MongoDB collections can be indexed for optimal performance. MongoDB ecosystem is highly available, supports query services as well as MapReduce. It is often used in high volume content management system. CouchDB CouchDB databases are composed of documents which consists fields and attachments (known as description). It supports ACID properties. The main attraction points of CouchDB are that it will continue to operate even though network connectivity is sketchy. Due to this nature CouchDB prefers local data storage. Document Database is a good choice of the database when users have to generate dynamic reports from elements which are changing very frequently. A good example of document usages is in real time analytics in social networking or content management system. Tomorrow In tomorrow’s blog post we will discuss about various other Operational Databases supporting Big Data.

  • Oredev 2011 Trip Report

    - by arungupta
    Oredev had its seventh annual conference in the city of Malmo, Sweden last week. The name "Oredev" signifies to the part that Malmo is connected with Copenhagen with Oresund bridge. There were about 1000 attendees with several speakers from all over the world. The first two days were hands-on workshops and the next three days were sessions. There were different tracks such as Java, Windows 8, .NET, Smart Phones, Architecture, Collaboration, and Entrepreneurship. And then there was Xtra(ck) which had interesting sessions not directly related to technology. I gave two slide-free talks in the Java track. The first one showed how to build an end-to-end Java EE 6 application using NetBeans and GlassFish. The complete instructions to build the application are explained in detail here. This 3-tier application used Java Persistence API, Enterprsie Java Beans, Servlet, Contexts and Dependency Injection, JavaServer Faces, and Java API for RESTful Services. The source code built during the application can be downloaded here (LINK TBD). The second session, slide-free again, showed how to take a Java EE 6 application into production using GlassFish cluster. It explained: Create a 2-instance GlassFish cluster Front-end with a Web server and a load balancer Demonstrate session replication and fail over Monitor the application using JavaScript The complete instructions for this session are available here. Oredev has an interesting way of collecting attendee feedback. The attendees drop a green, yellow, or red card in a bucket as they walk out of the session. Not everybody votes but most do. Other than the instantaneous feedback provided on twitter, this mechanism provides a more coarse grained feedback loop as well. The first talk had about 67 attendees (with 23 green and 7 yellow) and the second one had 22 (11 green and 11 yellow). The speakers' dinner is a good highlight of the conference. It is arranged in the historic city hall and the mayor welcomed all the speakers. As you can see in the pictures, it is a very royal building with lots of history behind it. Fortunately the dinner was a buffet with a much better variety unlike last year where only black soup and geese were served, which was quite cultural BTW ;-) The sauna in 85F, skinny dipping in 35F ocean and alternating between them at Kallbadhus is always very Swedish. Also spent a short evening at a friend's house socializing with other speaker/attendees, drinking Glogg, and eating Pepperkakor.  The welcome packet at the hotel also included cinnamon rolls, recommended to drink with cold milk, for a little more taste of Swedish culture. Something different at this conference was how artists from Image Think were visually capturing all the keynote speakers using images on whiteboards. Here are the images captured for Alexis Ohanian (Reddit co-founder and now running Hipmunk): Unfortunately I could not spend much time engaging with other speakers or attendees because was busy preparing a new hands-on lab material. But was able to spend some time with Matthew Mccullough, Micahel Tiberg, Magnus Martensson, Mattias Karlsson, Corey Haines, Patrick Kua, Charles Nutter, Tushara, Pradeep, Shmuel, and several other folks. Here are a few pictures captured from the event: And the complete album here: Thank you Matthias, Emily, and Kathy for putting up a great show and giving me an opportunity to speak at Oredev. I hope to be back next year with a more vibrant representation of Java - the language and the ecosystem!

  • What packages do I need to compile .tex documents using XeLaTeX?

    - by maria
    Hi I'm aware of the existence of similar threads on this forum. But any of replies mach to my problem. I'm using Ubuntu 10.4 and I hadn't problems with fonts till I've decided to use XeLaTeX instead of LaTeX (cf http://tex.stackexchange.com/questions/12347/typesetting-a-document-using-arabic-script/12358#12358). The problem is that I'm not able to compile any .tex document using XeLaTeX, as well as properly display XeLaTeX documentation. As I've learn thanks to mentioned thread, XeLaTeX uses the fonts availables in general in the system. I was trying yo read fontspec documentation, but it opens in pdf with a lot of white gaps and terminal output (quite long) consist mostly of errors. This are just few lines of it: Error: Missing language pack for 'Adobe-Japan1' mapping Error: Unknown font tag 'F5.1' Error (24124): No font in show Error: Unknown font tag 'F5.1' I was trying to compile simple XeLaTeX file: \documentclass{article} \usepackage{fontspec} \setmainfont{Linux Libertine O} \begin{document} Hello World! \end{document} without succes.

  • and the winner is Google Chrome

    - by anirudha
    Browser war really still uncompleted but here i tell that Why Google chrome better. 1. Easy to install:- as IE 9 Google chrome not force user to purchase a new OS. the chrome have a facelity that they install in minutes then less then other just like Firefox a another competitor or bloody fool  IE 9. 2. Easy to test: if you want to test their beta that’s no problem as well as Firefox. if user use Firefox 4 beta that they found that they can’t use many good plugin such as a big list the Web Developer tool and many other are one of them. in Chrome beta they provide you more then the last official release of chrome. 3. Google chrome Sync:-  i myself used  sync inside Firefox but nothing i found good and from a long time i feel nothing good and any feature in Firefox sync. but in google chrome their sync system is much better. When user login for sync in chrome they install everything and get back the user every settings they set the last time such as apps, autofill, bookmark ,extensions preference and theme. if you want to check bookmark from other browser that you can use google docs because google provided their bookmark backup in their docs account they have. performance:- after testing a website i found that a website open in 36 seconds in Firefox that Google chrome open them in 10 seconds. i found a interesting thing that when i test offline in IE 8 they show me in one or two seconds. i wonder how it’s possible after a long puzzle i found that IE was integrated software from Microsoft that the both software Visual studio and IE was integrated with windows. if user  test javascript in IE that the error they find show in visual studio not in IE as well as other software like chrome and IE. chrome not have a vast range of plugin as well as firefox so developer spent less time on chrome that would be a problem of future of chrome. interface comparison : the chrome have a common but user friendly interface then the user easily can use them. are you watching menu in Firefox 4. they make them complex as well as whole software IE 9. IE developer team thing that they can make everything fool by making a slogan HTML 5 inside IE. if anyone want to open a page in IE 9 that they show after some second. some time they show page not found even site is not gone wrong. when anyone want to use IE 9 developer tool that they thing that “ are this really  a developer tool ? ”. yeah they not make them for human as well as Firebug working team make firebug inside Firefox. they thing that how they can make public fool. Are you see that if you want to install Visual studio they force you to install sql server even you use other database system. a big stupidity of their tool can be found here today we hear that they Microsoft launched silverlight 5. are you know how Microsoft make silverlight yeah he copycat the idea of Adobe and their product Adobe Flash. that’s a other matter we can use .Net language instead of actionscript , lingo or shockwave.

  • 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

  • HTML5 Boilerplate template for ASP.NET with Visual Studio 2010

    - by Harish Ranganathan
    This is the 5th post in the series of HTML5 for ASP.NET Developers  Support for HTML5 in Visual Studio 2010 has been quite good with Visual Studio Service Pack 1 However, HTML5 Boilerplate template has been one of the most popular HTML5 templates out in the internet.  Now, there is one for your favorite ASP.NET Webforms as well as ASP.NET MVC 3 Projects (even for ASP.NET MVC 2).  And its available in the most optimal place, i.e. NuGet. Lets see it in action.  Let us fire up Visual Studio 2010 and create a “File – New Project – ASP.NET Web Application” and leave the default name to create the project.  The default project template creates Site.Master, Default.aspx and the Account (membership) files. When you run the project without any changes, it shows up the default Master Page with the Home and About placeholder pages. Also, just to check the rendering on devices, lets try running the same page in Windows Phone 7 Emulator.  You can download the SDK from here Clearly, it looks bad on the emulator and if we were to publish the application as is, its going to be the same experience when users browse this app. Close the browser and then switch to Visual Studio.   Right click on the project and select “Manage NuGet Packages” The NuGet Package Manager dialog opens up.  Search for HTML5 Boilerplate.  The options for MVC & Web Forms show up.  Click on Install corresponding to the “Add HTML5 Boilerplate to Web Forms” options. It installs the template in a few seconds.   Once installed, you will be able to see a lot of additional Script files and also the all important HTML5Boilerplate.Master file.  This would be the replacement for the default Site.Master.  We need to change the Content Pages (Default.aspx & other pages) to point to this Master Page.  Example <%@ <% Master Language="C#" AutoEventWireup="true" CodeBehind="Html5Boilerplate.Master.cs" Inherits="WebApplication14.SiteMaster" %> would be the setting in the Default.aspx Page. You can do a Find & Replace for Site.Master to HTML5Boilerplate.Master for the whole solution so that it is changed in all the locations. With this, we have our Webforms application ready with HTML5 capabilities.  Needless to say, we need to wire up HTML5 mark up level code, canvas, etc., further to use the actual HTML5 features, but even without that, the page is now HTML5’ed.   One of the advantages of HTML5 (here HTML5 is collectively referred for CSS3, Javascript enhancements etc.,)  is the ability to render the pages better on mobile and hand held devices. So, now when we run the page from Visual Studio, the following is what we get.  Notice the site.icon automatically added.  The page otherwise looks similar to what it was earlier. Now, when we also check this page on the Windows Phone Emulator, here below is what, we get. As you can see, we definitely get a better experience now.  Of course, this is not the only HTML5 feature that we can use.  We need to wire up additional code for using Canvas, SVG and other HTML5 features.  But, definitely, this is a good starting point. You can also install the HTML5boilerplate Template for your ASP.NET MVC 3 and ASP.NET MVC 2 from the NuGet packages and get them ready for HTML5. Cheers !!!

  • Why SQL Developer Rocks for the Advanced User Too

    - by thatjeffsmith
    While SQL Developer may be ‘perfect for Oracle beginners,’ that doesn’t preclude advanced and intermediate users from getting their fair share of toys! I’ve been working with Oracle since the 7.3.4 days, and I think it’s pretty safe to say that the WAY an ‘old timer’ uses a tool like SQL Developer is radically different than the ‘beginner.’ If you’ve been reluctant to use SQL Developer because it’s a GUI, give me a few minutes to try to convince you it’s worth a second (or third) look. 1. Help when you want it, and only when you want it One of the biggest gripes any user has with a piece of software is when said software can’t get out of it’s own way. When you’re typing in a word processor, sometimes you can do without the grammar and spelling checks, the offer to auto-complete your words, and all of the additional mark-up. This drives folks to programs like Notepad++ and vi. You can disable the code insight feature so you can type unmolested by SQL Developer’s attempt to auto-complete your object names. Now, if you happen to come across a long or hard to spell object name, you can still invoke the feature on demand using Ctrl+Spacebar Code Editor – Completion Insight – Enable Completion Auto-Popup (Keyword being Auto) 2. Automatic File Tracking SQL*Minus is nice. Vi is cool. Notepad++ has a lot of features I like. But not too many editors offer automatic logging of changes to your files without having to setup a source control system. I was doing some work on my login.sql. I’m not doing anything crazy, but seeing what I had done in previous iterations was helpful. Now imagine how nice it would be to have this available for your l,000+ line scripts! Track your scripts as they change, no setup required! 3. Extend the Functionality Know SQL and XML? Wish SQL Developer did JUST a little bit more? Build your own extensions. You can have custom context menus and object pages in just a few minutes. This is an example of lazy developers writing code that write code. 4. Get Your Money’s Worth You’ve licensed Enterprise Edition. You got your Diagnostic and Tuning packs. Now start using them! Not everyone has access to Enterprise Manager, especially developers. But that doesn’t mean they don’t need help with troubleshooting and optimizing poorly performing SQL statements. ASH, AWR, Real-Time SQL Monitoring and the SQL Tuning Advisor are built into the Reports and Worksheet. Yes you could make the package calls, but that’s a whole lot of typing, and I’d rather just get to the results. 5. Profile, Debug, & Unit Testing PLSQL An Interactive Development Environment (IDE) built by the same folks that own the programming language (Hello – Oracle PLSQL!) should be complete. It should ‘hug’ the developer and empower them to churn out programs that work, run fast, and are easy to maintain. Write it, test it, debug it, and tune it. When you’re running your programs and you just want to see the data that’s returned, that shouldn’t require any special settings or workaround to make it happen either. Magic! And a whole lot more… I could go on and talk about the support for things like DataPump, RMAN, and DBMS_SCHEDULER, but you’re experts and you’re plenty busy. If you think SQL Developer is falling short somewhere, I want you to let us know about it.

  • Big Data – Data Mining with Hive – What is Hive? – What is HiveQL (HQL)? – Day 15 of 21

    - by Pinal Dave
    In yesterday’s blog post we learned the importance of the operational database in Big Data Story. In this article we will understand what is Hive and HQL in Big Data Story. Yahoo started working on PIG (we will understand that in the next blog post) for their application deployment on Hadoop. The goal of Yahoo to manage their unstructured data. Similarly Facebook started deploying their warehouse solutions on Hadoop which has resulted in HIVE. The reason for going with HIVE is because the traditional warehousing solutions are getting very expensive. What is HIVE? Hive is a datawarehouseing infrastructure for Hadoop. The primary responsibility is to provide data summarization, query and analysis. It  supports analysis of large datasets stored in Hadoop’s HDFS as well as on the Amazon S3 filesystem. The best part of HIVE is that it supports SQL-Like access to structured data which is known as HiveQL (or HQL) as well as big data analysis with the help of MapReduce. Hive is not built to get a quick response to queries but it it is built for data mining applications. Data mining applications can take from several minutes to several hours to analysis the data and HIVE is primarily used there. HIVE Organization The data are organized in three different formats in HIVE. Tables: They are very similar to RDBMS tables and contains rows and tables. Hive is just layered over the Hadoop File System (HDFS), hence tables are directly mapped to directories of the filesystems. It also supports tables stored in other native file systems. Partitions: Hive tables can have more than one partition. They are mapped to subdirectories and file systems as well. Buckets: In Hive data may be divided into buckets. Buckets are stored as files in partition in the underlying file system. Hive also has metastore which stores all the metadata. It is a relational database containing various information related to Hive Schema (column types, owners, key-value data, statistics etc.). We can use MySQL database over here. What is HiveSQL (HQL)? Hive query language provides the basic SQL like operations. Here are few of the tasks which HQL can do easily. Create and manage tables and partitions Support various Relational, Arithmetic and Logical Operators Evaluate functions Download the contents of a table to a local directory or result of queries to HDFS directory Here is the example of the HQL Query: SELECT upper(name), salesprice FROM sales; SELECT category, count(1) FROM products GROUP BY category; When you look at the above query, you can see they are very similar to SQL like queries. Tomorrow In tomorrow’s blog post we will discuss about very important components of the Big Data Ecosystem – Pig.

  • AppKata - Enter the next level of programming exercises

    - by Ralf Westphal
    Doing CodeKatas is all the rage lately. That´s great since widely accepted exercises are important to further the art. They provide a means of communication across platforms and allow to compare results which is part of any deliberate practice. But CodeKatas suffer from their size. They are intentionally small, so they can be done again and again. Repetition helps to build habit and to dig deeper. Over time ever new nuances of the problem or one´s approach become visible. On the other hand, though, their small size limits the methods, techniques, technologies that can be applied. To improve your TDD skills doing CodeKatas might be enough. But what about other skills? Developing on a software in a team, designing larger pieces of software, iteratively releasing software… all this and more is kinda hard to train using the tiny CodeKata problems. That´s why I´d like to present here another kind of kata I call Application Kata (or just AppKata). AppKatas are larger programming problems. They require the development of “whole” applications, i.e. not just one class or method, but bunches of classes accessible through a user interface. Also AppKata problems always are split into iterations. To get the most out of them, just look at the requirements of one iteration at a time. This way you´re closer to reality where requirements evolve in unexpected ways. So if you´re looking for more of a challenge for your software development skills, check out these AppKatas – or invent your own. AppKatas are platform independent like CodeKatas. Use whatever programming language and IDE you like. Also use whatever approach to software development you like. Just be sensitive to how easy it is to evolve your code across iterations. Reflect on what went well and what not. Compare your solutions with others. Or – for even more challenge – go for the “Coding Carousel” (see below). CSV Viewer An application to view CSV files. Sounds easy, but watch out! Requirements sometimes drastically change if the customer is happy with what you delivered. Iteration 1 Iteration 2 Iteration 3 Iteration 4 Iteration 5 (to come) Questionnaire If you like GUI programming, this AppKata might be for you. It´s about an app to let people fill out questionnaires. Also this problem might be interestin for you, if you´re into DDD. Iteration 1 Iteration 2 (to come) Iteration 3 (to come) Iteration 4 (to come) Tic Tac Toe For developers who like game programming. Although Tic Tac Toe is a trivial game, this AppKata poses some interesting infrastructure challenges. The GUI, however, stays simple; leave any 3D ambitions at home ;-) Iteration 1 Iteration 2 (to come) Iteration 3 (to come) Iteration 4 (to come) Iteration 5 (to come) Coding Carousel There are many ways you can do AppKatas. Work on them alone or in a team, pitch several devs against each other in an AppKata contest – or go around in a Coding Carousel. For the Coding Carousel you need at least 3 dev teams (regardless of size). All teams work on the same iteration at the same time. But here´s the trick: After each iteration the teams swap their code. Whatever they did for iteration n will be the basis for changes another team has to apply in iteration n+1. The code is going around the teams like in a carousel. I promise you, that´s gonna be fun! :-)

  • AIX Checklist for stable obiee deployment

    - by user554629
    Common AIX configuration issues     ( last updated 27 Aug 2012 ) OBIEE is a complicated system with many moving parts and connection points.The purpose of this article is to provide a checklist to discuss OBIEE deployment with your systems administrators. The information in this article is time sensitive, and updated as I discover new  issues or details. What makes OBIEE different? When Tech Support suggests AIX component upgrades to a stable, locked-down production AIX environment, it is common to get "push back".  "Why is this necessary?  We aren't we seeing issues with other software?"It's a fair question that I have often struggled to answer; here are the talking points: OBIEE is memory intensive.  It is the entire purpose of the software to trade memory for repetitive, more expensive database requests across a network. OBIEE is implemented in C++ and is very dependent on the C++ runtime to behave correctly. OBIEE is aggressively thread efficient;  if atomic operations on a particular architecture do not work correctly, the software crashes. OBIEE dynamically loads third-party database client libraries directly into the nqsserver process.  If the library is not thread-safe, or corrupts process memory the OBIEE crash happens in an unrelated part of the code.  These are extremely difficult bugs to find. OBIEE software uses 99% common source across multiple platforms:  Windows, Linux, AIX, Solaris and HPUX.  If a crash happens on only one platform, we begin to suspect other factors.  load intensity, system differences, configuration choices, hardware failures.  It is rare to have a single product require so many diverse technical skills.   My role in support is to understand system configurations, performance issues, and crashes.   An analyst trained in Business Analytics can't be expected to know AIX internals in the depth required to make configuration choices.  Here are some guidelines. AIX C++ Runtime must be at  version 11.1.0.4$ lslpp -L | grep xlC.aixobiee software will crash if xlC.aix.rte is downlevel;  this is not a "try it" suggestion.Nov 2011 11.1.0.4 version  is appropriate for all AIX versions ( 5, 6, 7 )Download from here:https://www-304.ibm.com/support/docview.wss?uid=swg24031426 No reboot is necessary to install, it can even be installed while applications are using the current version.Restart the apps, and they will pick up the latest version. AIX 5.3 Technology Level 12 is required when running on Power5,6,7 processorsAIX 6.1 was introduced with the newer Power chips, and we have seen no issues with 6.1 or 7.1 versions.Customers with an unstable deployment, dozens of unexplained crashes, became stable after the upgrade.If your AIX system is 5.3, the minimum TL level should be at or higher than this:$ oslevel -s  5300-12-03-1107IBM typically supports only the two latest versions of AIX ( 6.1 and 7.1, for example).  AIX 5.3 is still supported and popular running in an LPAR. obiee userid limits$ ulimit -Ha  ( hard limits )$ ulimit -a   ( default limits )core file size (blocks)     unlimiteddata seg size (kbytes)      unlimitedfile size (blocks)          unlimitedmax memory size (kbytes)    unlimitedopen files                  10240 cpu time (seconds)          unlimitedvirtual memory (kbytes)     unlimitedIt is best to establish the values in /etc/security/limitsroot user is needed to observe and modify this file.If you modify a limit, you will need to relog in to change it again.  For example,$ ulimit -c 0$ ulimit -c 2097151cannot modify limit: Operation not permitted$ ulimit -c unlimited$ ulimit -c0There are only two meaningful values for ulimit -c ; zero or unlimited.Anything else is likely to produce a truncated core file that cannot be analyzed. Deploy 32-bit or 64-bit ?Early versions of OBIEE offered 32-bit or 64-bit choice to AIX customers.The 32-bit choice was needed if a database vendor did not supply a 64-bit client library.That's no longer an issue and beginning with OBIEE 11, 32-bit code is no longer shipped.A common error that leads to "out of memory" conditions to to accept the 32-bit memory configuration choices on 64-bit deployments.  The significant configuration choices are: Maximum process data (heap) size is in an AIX environment variableLDR_CNTRL=IGNOREUNLOAD@LOADPUBLIC@PREREAD_SHLIB@MAXDATA=0x... Two thread stack sizes are made in obiee NQSConfig.INI[ SERVER ]SERVER_THREAD_STACK_SIZE = 0;DB_GATEWAY_THREAD_STACK_SIZE = 0; Sort memory in NQSConfig.INI[ GENERAL ]SORT_MEMORY_SIZE = 4 MB ;SORT_BUFFER_INCREMENT_SIZE = 256 KB ; Choosing a value for MAXDATA:0x080000000  2GB Default maximum 32-bit heap size ( 8 with 7 zeros )0x100000000  4GB 64-bit breaking even with 32-bit ( 1 with 8 zeros )0x200000000  8GB 64-bit double 32-bit max0x400000000 16GB 64-bit safetyUsing 2GB heap size for a 64-bit process will almost certainly lead to an out-of-memory situation.Registers are twice as big ... consume twice as much memory in the heap.Upgrading to a 4GB heap for a 64-bit process is just "breaking even" with 32-bit.A 32-bit process is constrained by the 32-bit virtual addressing limits.  Heap memory is used for dynamic requirements of obiee software, thread stacks for each of the configured threads, and sometimes for shared libraries. 64-bit processes are not constrained in this way;  extra heap space can be configured for safety against a query that might create a sudden requirement for excessive storage.  If the storage is not available, this query might crash the whole server and disrupt existing users.There is no performance penalty on AIX for configuring more memory than required;  extra memory can be configured for safety.  If there are no other considerations, start with 8GB.Choosing a value for Thread Stack size:zero is the value documented to select an appropriate default for thread stack size.  My preference is to change this to an absolute value, even if you intend to use the documented default;  it provides better documentation and removes the "surprise" factor.There are two thread types that can be configured. GATEWAY is used by a thread pool to call a database client library to establish a DB connection.The default size is 256KB;  many customers raise this to 512KB ( no performance penalty for over-configuring ). This value must be set to 1 MB if Teradata connections are used. SERVER threads are used to run queries.  OBIEE uses recursive algorithms during the analysis of query structures which can consume significant thread stack storage.  It's difficult to provide guidance on a value that depends on data and complexity.  The general notion is to provide more space than you think you need,  "double down" and increase the value if you run out, otherwise inspect the query to understand why it is too complex for the thread stack.  There are protections built into the software to abort a single user query that is too complex, but the algorithms don't cover all situations.256 KB  The default 32-bit stack size.  Many customers increased this to 512KB on 32-bit.  A 64-bit server is very likely to crash with this value;  the stack contains mostly register values, which are twice as big.512 KB  The documented 64-bit default.  Some early releases of obiee didn't set this correctly, resulting in 256KB stacks.1 MB  The recommended 64-bit setting.  If your system only ever uses 512KB of stack space, there is no performance penalty for using 1MB stack size.2 MB  Many large customers use this value for safety.  No performance penalty.nqscheduler does not use the NQSConfig.INI file to set thread stack size.If this process crashes because the thread stack is too small, use this to set 2MB:export OBI_BACKGROUND_STACK_SIZE=2048 Shared libraries are not (shared) When application libraries are loaded at run-time, AIX makes a decision on whether to load the libraries in a "public" memory segment.  If the filesystem library permissions do not have the "Read-Other" permission bit, AIX loads the library into private process memory with two significant side-effects:* The libraries reduce the heap storage available.      Might be significant in 32-bit processes;  irrelevant in 64-bit processes.* Library code is loaded into multiple real pages for execution;  one copy for each process.Multiple execution images is a significant issue for both 32- and 64-bit processes.The "real memory pages" saved by using public memory segments is a minor concern.  Today's machines typically have plenty of real memory.The real problem with private copies of libraries is that they consume processor cache blocks, which are limited.   The same library instructions executing in different real pages will cause memory delays as the i-cache ( instruction cache 128KB blocks) are refreshed from real memory.   Performance loss because instructions are delayed is something that is difficult to measure without access to low-level cache fault data.   The machine just appears to be running slowly for no observable reason.This is an easy problem to detect, and an easy problem to correct.Detection:  "genld -l" AIX command produces a list of the libraries used by each process and the AIX memory address where they are loaded.32-bit public segment is 13 ( "dxxxxxxx" ).   private segments are 2-a.64-bit public segment is 9 ( "9xxxxxxxxxxxxxxx") ; private segment is 8.genld -l | grep -v ' d| 9' | sort +2provides a list of privately loaded libraries. Repair: chmod o+r <libname>AIX shared libraries will have a suffix of ".so" or ".a".Another technique is to change all libraries in a selected directory to repair those that might not be currently loaded.   The usual directories that need repair are obiee code, httpd code and plugins, database client libraries and java.chmod o+r /shr/dir/*.a /shr/dir/*.so Configure your system for diagnosticsProduction systems shouldn't crash, and yet bad things happen to good software.If obiee software crashes and produces a core, you should configure your system for reliable transfer of the failing conditions to Oracle Tech Support.  Here's what we need to be able to diagnose a core file from your system.* fullcore enabled. chdev -lsys0 -a fullcore=true* core naming enabled. chcore -n on -d* ulimit must not truncate core. see item 3.* pstack.sh is used to capture core documentation.* obidoc is used to capture current AIX configuration.* snapcore  AIX utility captures core and libraries. Use the proper syntax. $ snapcore -r corename executable-fullpath   /tmp/snapcore will contain the .pax.Z output file.  It is compressed.* If cores are directed to a common directory, ensure obiee userid can write to the directory.  ( chcore -p /cores -d ; chmod 777 /cores )The filesystem must have sufficient space to hold a crashing obiee application.Use:  df -k  Check the "Free" column ( not "% Used" )  8388608 is 8GB. Disable Oracle Client Library signal handlingThe Oracle DB Client Library is frequently distributed with the sqlplus development kit.By default, the library enables a signal handler, which will document a call stack if the application crashes.   The signal handler is not needed, and definitely disruptive to obiee diagnostics.   It needs to be disabled.   sqlnet.ora is typically located at:   $ORACLE_HOME/network/admin/sqlnet.oraAdd this line at the top of the file:   DIAG_SIGHANDLER_ENABLED=FALSE Disable async query in the RPD connection pool.This might be an obiee 10.1.3.4 issue only ( still checking  )."async query" must be disabled in the connection pools.It was designed to enable query cancellation to a database, and turned out to have too many edge conditions in normal communication that produced random corruption of data and crashes.  Please ensure it is turned off in the RPD. Check AIX error report (errpt).Errors external to obiee applications can trigger crashes.  $ /bin/errpt -aHardware errors ( firmware, adapters, disks ) should be reported to IBM support.All application core files are recorded by AIX;  the most recent ones are listed first. Reserved for something important to say.

  • Low level programming - what's in it for me?

    - by back2dos
    For years I have considered digging into what I consider "low level" languages. For me this means C and assembly. However I had no time for this yet, nor has it EVER been neccessary. Now because I don't see any neccessity arising, I feel like I should either just schedule some point in time when I will study the subject or drop the plan forever. My Position For the past 4 years I have focused on "web technologies", which may change, and I am an application developer, which is unlikely to change. In application development, I think usability is the most important thing. You write applications to be "consumed" by users. The more usable those applications are, the more value you have produced. In order to achieve good usability, I believe the following things are viable Good design: Well-thought-out features accessible through a well-thought-out user interface. Correctness: The best design isn't worth anything, if not implemented correctly. Flexibility: An application A should constantly evolve, so that its users need not switch to a different application B, that has new features, that A could implement. Applications addressing the same problem should not differ in features but in philosophy. Performance: Performance contributes to a good user experience. An application is ideally always responsive and performs its tasks reasonably fast (based on their frequency). The value of performance optimization beyond the point where it is noticeable by the user is questionable. I think low level programming is not going to help me with that, except for performance. But writing a whole app in a low level language for the sake of performance is premature optimization to me. My Question What could low level programming teach me, what other languages wouldn't teach me? Am I missing something, or is it just a skill, that is of very little use for application development? Please understand, that I am not questioning the value of C and assembly. It's just that in my everyday life, I am quite happy that all the intricacies of that world are abstracted away and managed for me (mostly by layers written in C/C++ and assembly themselves). I just don't see any concepts, that could be new to me, only details I would have to stuff my head with. So what's in it for me? My Conclusion Thanks to everyone for their answers. I must say, nobody really surprised me, but at least now I am quite sure I will drop this area of interest until any need for it arises. To my understanding, writing assembly these days for processors as they are in use in today's CPUs is not only unneccesarily complicated, but risks to result in poorer runtime performance than a C counterpart. Optimizing by hand is nearly impossible due to OOE, while you do not get all kinds of optimizations a compiler can do automatically. Also, the code is either portable, because it uses a small subset of available commands, or it is optimized, but then it probably works on one architecture only. Writing C is not nearly as neccessary anymore, as it was in the past. If I were to write an application in C, I would just as much use tested and established libraries and frameworks, that would spare me implementing string copy routines, sorting algorithms and other kind of stuff serving as exercise at university. My own code would execute faster at the cost of type safety. I am neither keen on reeinventing the wheel in the course of normal app development, nor trying to debug by looking at core dumps :D I am currently experimenting with languages and interpreters, so if there is anything I would like to publish, I suppose I'd port a working concept to C, although C++ might just as well do the trick. Again, thanks to everyone for your answers and your insight.

  • Serving up a RSS feed in MVC using WCF Syndication

    - by brian_ritchie
    With .NET 3.5, Microsoft added the SyndicationFeed class to WCF for generating ATOM 1.0 & RSS 2.0 feeds.  In .NET 3.5, it lives in System.ServiceModel.Web but was moved into System.ServiceModel in .NET 4.0. Here's some sample code on constructing a feed: .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; } 1: SyndicationFeed feed = new SyndicationFeed(title, description, new Uri(link)); 2: feed.Categories.Add(new SyndicationCategory(category)); 3: feed.Copyright = new TextSyndicationContent(copyright); 4: feed.Language = "en-us"; 5: feed.Copyright = new TextSyndicationContent(DateTime.Now.Year + " " + ownerName); 6: feed.ImageUrl = new Uri(imageUrl); 7: feed.LastUpdatedTime = DateTime.Now; 8: feed.Authors.Add(new SyndicationPerson() { Name = ownerName, Email = ownerEmail }); 9:   10: var feedItems = new List<SyndicationItem>(); 11: foreach (var item in Items) 12: { 13: var sItem = new SyndicationItem(item.title, null, new Uri(link)); 14: sItem.Summary = new TextSyndicationContent(item.summary); 15: sItem.Id = item.id; 16: if (item.publishedDate != null) 17: sItem.PublishDate = (DateTimeOffset)item.publishedDate; 18: sItem.Links.Add(new SyndicationLink() { Title = item.title, Uri = new Uri(link), Length = item.size, MediaType = item.mediaType }); 19: feedItems.Add(sItem); 20: } 21: feed.Items = feedItems;   Then, we create a custom ContentResult to serialize the feed & stream it to the client: 1: public class SyndicationFeedResult : ContentResult 2: { 3: public SyndicationFeedResult(SyndicationFeed feed) 4: : base() 5: { 6: using (var memstream = new MemoryStream()) 7: using (var writer = new XmlTextWriter(memstream, System.Text.UTF8Encoding.UTF8)) 8: { 9: feed.SaveAsRss20(writer); 10: writer.Flush(); 11: memstream.Position = 0; 12: Content = new StreamReader(memstream).ReadToEnd(); 13: ContentType = "application/rss+xml" ; 14: } 15: } 16: } Finally, we wire it up through the controller: 1: public class RssController : Controller 2: { 3: public SyndicationFeedResult Feed() 4: { 5: var feed = new SyndicationFeed(); 6: // populate feed... 7: return new SyndicationFeedResult(feed); 8: } 9: }   In the next post, I'll discuss how to add iTunes markup to the feed to publish it on iTunes as a Podcast.
