  • Confused about NoMethodError in Ruby

    - by E L
    In a simple Ruby example, I'm getting an error that does not occur in irb. name = "Joe" def say_hi "\"Hi there!\" said #{self}" end response = name.say_hi puts response This code should return, "Hi there!" said Joe. It works perfectly fine in irb. However, when I attempt to put the same code in a file and run the file, I get this error: say_hi.rb:8:in `<main>': private method `say_hi' called for "Joe":String (NoMethodError) Any suggestion about why this happens?

  • KDE4: Share Nepomuk data

    - by Frank Becker
    Hi all, is it possible to share the nepomuk data? I have several users here and the users should be able to read and modify the tags and comments for each file with public access. Also it should be possible to tag and comment the files in each private home-directory. Is this possible with the current KDE 4.3.2? Thanks for your help Frank

  • Windows 2008 R2 Terminal Server - RemoteApp - Option "Start in" available?

    - by Frank
    we have set up a Windows 2008 R2 Terminal Server. On this server, we want to run an application which needs another path for the option "Start in" than the application itself. In a shortcut, this is no problem (for example, the "Target" is C:\app\bin\application.exe and the "Start in:" is C:\app\users\user1). But I have no option for "Start in" when I configure the RemoteApp so the application fails to start. Is there any possibility? Thank you in advance Frank

  • Why would cat6 connectors not work with cat5e patch cable?

    - by Lee Tickett
    I had a naff batch of cat5 connectors (the latching mechanism didn't work) so decided to order in some cat6 connectors in preparation for the inevitable upgrade. My existing reel of for making patch cables is cat5e utp stranded. I made up a few cables and tested them- none of them worked. I recrimped and still nothing. When i check them with a multi-meter not all pins are connected. This reel has always worked with the previous cat5 connectors so I tested the cat6 connectors on a reel of solid cat5e cable and they work fine. Any ideas what I might be doing wrong? Or what might be at fault? (cable/connectors) and how I can diagnose? Thanks Lee

  • Named pipe blocking with user nobody

    - by dnagirl
    I have 2 short scripts. The first, an awk script, processes a large file and prints to a named pipe 'myfifo.dat'. The second, a Perl script, runs a LOAD DATA LOCAL INFILE 'myfifo.dat'... command. Both of these scripts work when run locally like so: lee.awk big.file & lee.pl However, when I call these scripts from a PHP webpage, the named pipe blocks: $awk="/path/to/lee.awk {$_FILES['uploadfile']['tmp_name']} &"; $sql="/path/to/lee.pl"; if(!exec($awk,$return,$err)) throw new ZException(print_r($err,true)); //blocks here if(!exec($sql,$return,$err)) throw new ZException(print_r($err,true)); If I modify the awk and Perl scripts so that they write and read to a normal file, everything works fine from PHP. The permissions on the fifo and the normal file are 666 (for testing purposes). These operations run much more quickly through a named pipe, so I'd prefer to use one. Any ideas how to unblock it? ps. In case you're wondering why I'm going to all this aggravation, see this SO question.

  • The Missing Post

    - by Joe Mayo
    It’s somewhat of a mystery how the writing process can conjure up results that weren’t initially intended. Case in point is the fact that another post was planned to be in place of this one, but it never made the light of day.  This particular post started off as an introduction to a technology I had just learned, used, and wanted to share the experience with others.  The beginning was fun and demonstrated how easy it was to get started.  One of the things I’ve been pondering over time is that the Web is filled with introductions to new technologies and quick first looks, so I set out to add more depth, share lessons learned, and generally help you avoid the problems I encountered along the way; problems being a key theme of why you aren’t reading that post at this very minute.  Problems that curiously came from nowhere to thwart my good intentions. Success was sweet when using the tool for the prototypical demo scenario. The thing is, I intended the tool to accomplish a real task.  Having embarked on the path toward getting the job done, glitches began creeping into the process.  Realizing that this was all a bit new, I had patience and found a suitable work-around, but this was to be short lived. As in marching ants to a freshly laid out picnic, the problems kept coming until I had to get up and walk away.  Not to be outdone, sheer will and brute force manual intervention led to mission accomplishment.  Though I kept a positive outlook and was pleased at the final result, the process of using the tool had somewhat soured. Regardless of a less than stellar experience with the tool, I have a great deal of respect for the company that produced it and the people who built it. Perhaps I empathize for what they might feel after reading a post that details such deficiencies in their product.  Sure, if you’re in this business, you’ve got to have a thick skin; brush it off, fix the problem, and move on to greatness. But, today I feel like they’re people and are probably already aware of any issues I would seemingly reveal.  Anyone who builds a product or provides a service takes a lot of pride in what they do.  Sometimes they screw up and if their worth a dime, they make it up. I think that will happen in this case and there’s no reason why I should post information that has the potential to sound more negative than helpful.  While no one would ever notice or care either way, I’m posting something that won’t harm.

  • ADF Mobile @ Oracle Open World 2012 - A Look Back...

    - by Joe Huang
    Hi, everyone: It's been a little over two weeks since the end of Oracle Open World 2012, and hope everyone has recovered sufficiently.  We have seen a tremendous amount of coverage on Oracle ADF Mobile during this Oracle Open World.  For starters, ADF Mobile demo booth was positioned in the Oracle Red Lounge in Moscone North, where all new and innovative technologies are being demonstrated.  The booth is liternally out front and the first booth in the area, and we had a lot of interested attendees talking to us.  It feels like ADF Mobile has finally arrived on the big stage. There are numerous sessions and hands on labs that covers ADF Mobile.  Details can be found in Oracle Open World page.   The Oracle Cloud: Oracle's Cloud Platofrm and Application Strategy by Thomas Kurian (Keynote) Near the beginning of the keynote, showing a great analytics application built using ADF Mobile  Oracle Fusion Middleware Strategies Driving Business Innovation by Hasan Rizvi (Keynote) The Future of Development for Oracle Fusion—From Desktop to Mobile to Cloud by Chris Tonas (General Session) Co-presented with Accenture, an ADF Mobile Beta Partner Extend Oracle Fusion Apps to Tablets/Smartphones with Oracle Mobile Technology (General Session) Extend Oracle Applications to Mobile Devices with Oracle’s Mobile Technologies (General Session) Building Mobile Applications with Oracle Cloud (General Session) Mobile-Enable Oracle Fusion Middleware and Enterprise Applications with Oracle ADF (Conference Session) Co-presented with Infosys, an ADF Mobile Beta Partner Develop On-Device iPhone and iPad Apps Without Writing Any Objective-C Code (Oracle Develop Session) Mobile Apps for Oracle E-Business Suite with Oracle ADF Mobile and Oracle SOA Suite (Conference Session) Developing Applications for Mobile iOS and Android Devices with Oracle ADF Mobile (Hands on Lab) This lab was repeated 8 (!) times Build Mobile Applications for Oracle E-business Suite (Hands on Lab) It was an extremely busy Open World for the team, and we were in the middle of trying to release ADF Mobile!   By far, the most memorable event during Open World was the ADF Meett Up at the OTN Lounge, where beers were flowing (for a little while) and familiar names are finally matched with faces.  We also appreciate the opportunity to interview the attendees from New Caledonia - sorry we probably surprised you with the video record, and many thanks for coming through for us. I also want to thank my fellow ADF Mobile and Fusion Middleware team members - from product managers, engineers, and product marketing, everyone worked extremely hard to make this Open World a great success for ADF Mobile. I really enjoyed meeting everyone at Oracle Open World, at the booth, sessions, etc.   Now it's on to release ADF Mobile - for real! Thanks, Joe Huang PS: If this thread shows up on your RSS feed, please keep watching...

  • BI and EPM Landscape

    - by frank.buytendijk
    Most of my blog entries are not about Oracle products, and most of the latest entries are about topics such as IT strategy and enterprise architecture. However, given my background at Gartner, and at Hyperion, I still keep a close eye on what's happening in BI and EPM. One important reason is that I believe there is significant competitive value for organizations getting BI and EPM right. Davenport and Harris wrote a great book called "Competing on Analytics", in which they explain this in a very engaging and convincing way. At Oracle we have defined the concept of "management excellence" that outlines what organizations have to do to keep or create a competitive edge. It's not only in the business processes, but also in the management processes. Recently, Gartner published its 2009 market shares report for BI, Analytics, and Performance Management. Gartner identifies the same three segments that Oracle does: (1) CPM Suites (Oracle refers not to Corporate Performance Management, but Enterprise Performance Management), (2) BI Platform, and (3) Analytic Applications & Performance Management. According to Gartner, Oracle's share is increasing with revenue growing by more than 5%. Oracle currently holds the #2 market share position in the overall BI Software space based on total BI software revenue. Source: Gartner Dataquest Market Share: Business Intelligence, Analytics and Performance Management Software, Worldwide, 2009; Dan Sommer and Bhavish Sood; Apr 2010 Gartner has ranked Oracle as #1 in the CPM Suites worldwide sub-segment based on total BI software revenue, and Oracle is gaining share with revenue growing by more than 6% in 2009. Source: Gartner Dataquest Market Share: Business Intelligence, Analytics and Performance Management Software, Worldwide, 2009; Dan Sommer and Bhavish Sood; Apr 2010 The Analytic Applications & Performance Management subsegment is more fragmented. It has for instance a very large "Other Vendors" category. The largest player traditionally is SAS. Analytic Applications are often meant for very specific analytic needs in very specific industry sectors. According to Gartner, from the large vendors, again Oracle is the one who is gaining the most share - with total BI software revenue growth close to 15% in 2009. Source: Gartner Dataquest Market Share: Business Intelligence, Analytics and Performance Management Software, Worldwide, 2009; Dan Sommer and Bhavish Sood; Apr 2010 I believe this shows Oracle's integration strategy is working. In fact, integration actually is the innovation. BI and EPM have been silo technology platforms and application suites way too long. Management and measuring performance should be very closely linked to strategy execution, which is the domain of other business application areas such as CRM, ERP, and Supply Chain. BI and EPM are not about "making better decisions" anymore, but are part of a tangible action framework. Furthermore, organizations are getting more serious about ecosystem thinking. They do not evaluate single tools anymore for different application areas, but buy into a complete ecosystem of hardware, software and services. The best ecosystem is the one that offers the most options, in environments where the uncertainty is high and investments are hard to reverse. The key to successfully managing such an environment is middleware, and BI and EPM become increasingly middleware intensive. In fact, given the horizontal nature of BI and EPM, sitting on top of all business functions and applications, you could call them "upperware". Many are active in the BI and EPM space. Big players can offer a lot, but there are always many areas that are covered by specialty vendors. Oracle openly embraces those technologies within the ecosystem as well. Complete, open and integrated still accurately describes the Oracle product strategy. frank

  • ADF Enterprise Application Development - Made Simple (Book Review)

    - by Frank Nimphius
      Sten E. Vesterli wrote the "Oracle ADF Enterprise Application Development – Made Simple" book published by Packt Publishing in 2011 http://www.packtpub.com/oracle-adf-enterprise-application-development/book A common question on OTN, but also when talking to clients or customers is about where and how to start your ADF application development. Especially when the current programming background is not in Java, but 4 GL or PLSQL, developers often look for answers to the following questions: · How long does it take to learn Oracle ADF ? · How long does it take to replace a Forms application with ADF ? · How many developers do I need? · Do I need to know Java to use ADF and if yes, how good do I need to know this? · How do I structure my programming files, organizing them in JDeveloper work spaces, projects and libraries? · What is best practices for naming Java packages and how to void naming conflicts in ADF in general? · How many Application Modules do I need or should I create? · How to test applications? Sten Vesterli answers all of the above questions and more in his book http://www.packtpub.com/oracle-adf-enterprise-application-development/book , which makes it great value add to the 3 existing Oracle ADF books. In order of complexity (which also is the order in which reading the available Oracle ADF books makes sense), in my opinion, Sten's book should come second – though it also is useful to those that are already more advanced with Oracle ADF. So if you are absolutely new to Oracle ADF, then the order of books to read to get you up on an expert level should be: 1. Grant Ronald; "Quick Start Guide to Oracle Fusion Development: Oracle JDeveloper and Oracle ADF" (McGraw Hill 2010) 2. Sten Vesterli; "Oracle ADF Enterprise Application Development – Made Simple" (Packt Publishing 2011) 3. Duncan Mills, Peter Koletzke; " Oracle JDeveloper 11g Handbook: A Guide to Fusion Web Development" (McGraw Hill 2009) 4. Frank Nimphius, Lynn Munsinger; " Oracle Fusion Developer Guide: Building Rich Internet Applications with Oracle ADF Business Components and Oracle ADF Faces" (McGraw Hill 2010) If you are not new to Oracle ADF and Orace JDeveloper, then buy Sten Vesterli's book anyway. It is worth it and you want to have it on your book shelf. See below the table of content to get a better idea of what this book covers: · Chapter 1: The ADF Proof of Concept · Chapter 2: Estimating the Effort · Chapter 3: Getting Organized · Chapter 4: Productive Teamwork · Chapter 5: Prepare to Build · Chapter 6: Building the Enterprise Application · Chapter 7: Testing your Application · Chapter 8: Look and Feel · Chapter 9: Customizing the Functionality · Chapter 10: Securing your ADF Application · Chapter 11: Package and Deliver · Appendix: Internationalization The book is written with a lot of good humor, which makes the read very enjoyable (from a geek's perspective, of course). My favorite quote – just in case you are interested - is from page 97, when Sten talks about getting organized: " Stop sending e-mails to your team. Just stop it. E-mail is so last century.…" So true, so true! This quote's runner up is the "boss key" on page 128 where Sten talks about productivity and how Oracle Team Productivity Center (TPC) can help you with this. Quotes like these stick to your brains and make sure you never forget. Go for it!

  • Book Review: Oracle ADF Real World Developer’s Guide

    - by Frank Nimphius
    Recently PACKT Publishing published "Oracle ADF Real World Developer’s Guide" by Jobinesh Purushothaman, a product manager in our team. Though already the sixth book dedicated to Oracle ADF, it has a lot of great information in it that none of the previous books covered, making it a safe buy even for those who own the other books published by Oracle Press (McGrwHill) and PACKT Publishing. More than the half of the "Oracle ADF Real World Developer’s Guide" book is dedicated to Oracle ADF Business Components in a depth and clarity that allows you to feel the expertise that Jobinesh gained in this area. If you enjoy Jobinesh blog (http://jobinesh.blogspot.co.uk/) about Oracle ADF, then, no matter what expert you are in Oracle ADF, this book makes you happy as it provides you with detail information you always wished to have. If you are new to Oracle ADF, then this book alone doesn't get you flying, but, if you have some Java background, accelerates your learning big, big, big times. Chapter 1 is an introduction to Oracle ADF and not only explains the layers but also how it compares to plain Java EE solutions (page 13). If you are new to Oracle JDeveloper and ADF, then at the end of this chapter you know how to start JDeveloper and begin your ADF development Chapter 2 starts with what Jobinesh really is good at: ADF Business Components. In this chapter you learn about the architecture ingredients of ADF Business Components: View Objects, View Links, Associations, Entities, Row Sets, Query Collections and Application Modules. This chapter also provides a introduction to ADFBC SDO services, as well as sequence diagrams for what happens when you execute queries or commit updates. Chapter 3 is dedicated to entity objects and  is one of many chapters in this book you will enjoy and never want to miss. Jobinesh explains the artifacts that make up an entity object, how to work with entities and resource bundles, and many advanced topics, including inheritance, change history tracking, custom properties, validation and cursor handling.  Chapter 4 - you guessed it - is all about View objects. Comparable to entities, you learn about the XM files and classes that make a view object, as well as how to define and work with queries. List-of-values, inheritance, polymorphism, bind variables and data filtering are interesting - and important topics that follow. Again the chapter provides helpful sequence diagrams for you to understand what happens internally within a view object. Chapter 5 focuses on advanced view object and entity object topics, like lifecycle callback methods and when you want to override them. This chapter is a good digest of Jobinesh's blog entries (which most ADF developers have in their bookmark list). Really worth reading ! Chapter 6 then is bout Application Modules. Beside of what application modules are, this chapter covers important topics like properties, passivation, activation, application module pooling, how and where to write custom logic. In addition you learn about the AM lifecycle and request sequence. Chapter 7 is about the ADF binding layer. If you are new to Oracle ADF and got lost in the more advanced ADF Business Components chapters, then this chapter is where you get back into the game. In very easy terms, Jobinesh explains what the ADF binding is, how it fits into the JSF request lifecycle and what are the metadata file involved. Chapter 8 then goes into building data bound web user interfaces. In this chapter you get the basics of JavaServer Faces (e.g. managed beans) and learn about the interaction between the JSF UI and the ADF binding layer. Later this chapter provides advanced solutions for working with tree components and list of values. Chapter 9 introduces bounded task flows and ADF controller. This is a chapter you want to read if you are new to ADF of have started. Experts don't find anything new here, which doesn't mean that it is not worth reading it (I for example, enjoyed the controller talk very much) Chapter 10 is an advanced coverage of bounded task flow and talks about contextual events  Chapter 11 is another highlight and explains error handling, trains, transactions and more. I can only recommend you read this chapter. I am aware of many documents that cover exception handling in Oracle ADF (and my Oracle Magazine article for January/February 2013 does the same), but none that covers it in such a great depth. Chapter 12 covers ADF best practices, which is a great round-up of all the tips provided in this book (without Jobinesh to repeat himself). Its all cool stuff that helps you with your ADF projects. In summary, "Oracle ADF Real World Developer’s Guide" by Jobinesh Purushothaman is a great book and addition for all Oracle ADF developers and those who want to become one. Frank

  • LINQ to Twitter Queries with LINQPad

    - by Joe Mayo
    LINQPad is a popular utility for .NET developers who use LINQ a lot.  In addition to standard SQL queries, LINQPad also supports other types of LINQ providers, including LINQ to Twitter.  The following sections explain how to set up LINQPad for making queries with LINQ to Twitter. LINQPad comes in a couple versions and this example uses LINQPad4, which runs on the .NET Framework 4.0. 1. The first thing you'll need to do is set up a reference to the LinqToTwitter.dll. From the Query menu, select query properties. Click the Browse button and find the LinqToTwitter.dll binary. You should see something similar to the Query Properties window below. 2. While you have the query properties window open, add the namespace for the LINQ to Twitter types.  Click the Additional Namespace Imports tab and type in LinqToTwitter. The results are shown below: 3. The default query type, when you first start LINQPad, is C# Expression, but you'll need to change this to support multiple statements.  Change the Language dropdown, on the Main window, to C# Statements. 4. To query LINQ to Twitter, instantiate a TwitterContext, by typing the following into the LINQPad Query window: var ctx = new TwitterContext(); Note: If you're getting syntax errors, go back and make sure you did steps #2 and #3 properly. 5. Next, add a query, but don't materialize it, like this: var tweets = from tweet in ctx.Status where tweet.Type == StatusType.Public select new { tweet.Text, tweet.Geo, tweet.User }; 6. Next, you want the output to be displayed in the LINQPad grid, so do a Dump, like this: tweets.Dump(); The following image shows the final results:   That was an unauthenticated query, but you can also perform authenticated queries with LINQ to Twitter's support of OAuth.  Here's an example that uses the PinAuthorizer (type this into the LINQPad Query window): var auth = new PinAuthorizer { Credentials = new InMemoryCredentials { ConsumerKey = "", ConsumerSecret = "" }, UseCompression = true, GoToTwitterAuthorization = pageLink => Process.Start(pageLink), GetPin = () => { // this executes after user authorizes, which begins with the call to auth.Authorize() below. Console.WriteLine("\nAfter you authorize this application, Twitter will give you a 7-digit PIN Number.\n"); Console.Write("Enter the PIN number here: "); return Console.ReadLine(); } }; // start the authorization process (launches Twitter authorization page). auth.Authorize(); var ctx = new TwitterContext(auth, "https://api.twitter.com/1/", "https://search.twitter.com/"); var tweets = from tweet in ctx.Status where tweet.Type == StatusType.Public select new { tweet.Text, tweet.Geo, tweet.User }; tweets.Dump(); This code is very similar to what you'll find in the LINQ to Twitter downloadable source code solution, in the LinqToTwitterDemo project.  For obvious reasons, I changed the value assigned to ConsumerKey and ConsumerSecret, which you'll have to obtain by visiting http://dev.twitter.com and registering your application. One tip, you'll probably want to make this easier on yourself by creating your own DLL that encapsulates all of the OAuth logic and then call a method or property on you custom class that returns a fully functioning TwitterContext.  This will help avoid adding all this code every time you want to make a query. Now, you know how to set up LINQPad for LINQ to Twitter, perform unauthenticated queries, and perform queries with OAuth. Joe

  • Comments on Comments

    - by Joe Mayo
    I almost tweeted a reply to Capar Kleijne's question about comments on Twitter, but realized that my opinion exceeded 140 characters. The following is based upon my experience with extremes and approaches that I find useful in code comments. There are a couple extremes that I've seen and reasons why people go the distance in each approach. The most common extreme is no comments in the code at all.  A few bad reasons why this happens is because a developer is in a hurry, sloppy, or is interested in job preservation. The unfortunate result is that the code is difficult to understand and hard to maintain. The drawbacks to no comments in code are a primary reason why teachers drill the need for commenting code into our heads.  This viewpoint assumes the lack of comments are bad because the code is bad, but there is another reason for not commenting that is gaining more popularity. I've heard/and read that code should be self documenting. Following this thought pattern, if code is well written with meaningful names, there should not be a reason for comments.  An addendum to this argument is that comments are often neglected and get out-of-date, but the code is what is kept up-to-date. Presumably, if code contained very good naming, it would be easy to maintain.  This is a noble perspective and I like the practice of meaningful naming of identifiers. However, I think it's also an extreme approach that doesn't cover important cases.  i.e. If an identifier is named badly (subjective differences in opinion) or not changed appropriately during maintenance, then the badly named identifier is no more useful than a stale comment. These were the two no-comment extremes, so let's look at the too many comments extreme. On a regular basis, I'll see cases where the code is over-commented; not nearly as often as the no-comment scenarios, but still prevalent.  These are examples of where every single line in the code is commented.  These comments make the code harder to read because they get in the way of the algorithm.  In most cases, the comments parrot what each line of code does.  If a developer understands the language, then most statements are immediately intuitive.  i.e. what use is it to say that I'm assigning foo to bar when it's clear what the code is doing. I think that over-commenting code is a waste of time that slows down initial development and maintenance.  Understandably, the developer's intentions are admirable because they've had it beaten into their heads that they must comment. However, I think it's an extreme and prefer a more moderate approach. I don't think the extremes do justice to code because each can make maintenance harder.  No comments on bad code is obviously a problem, but the other two extremes are subtle and require qualification to address properly. The problem I see with the code-as-documentation approach is that it doesn't lift the developer out of the algorithm to identify dependencies, intentions, and hacks. Any developer can read code and follow an algorithm, but they still need to know where it fits into the big picture of the application. Because of indirections with language features like interfaces, delegates, and virtual members, code can become complex.  Occasionally, it's useful to point out a nuance or reason why a piece of code is there. i.e. If you've building an app that communicates via HTTP, you'll have certain headers to include for the endpoint, and it could be useful to point out why the code for setting those header values is there and how they affect the application. An argument against this could be that you should extract that code into a separate method with a meaningful name to describe the scenario.  My problem with such an approach would be that your code base becomes even more difficult to navigate and work with because you have all of this extra code just to make the code more meaningful. My opinion is that a simple and well-stated comment stating the reasons and intention for the code is more natural and convenient to the initial developer and maintainer.  I just don't agree with the approach of going out of the way to avoid making a comment.  I'm also concerned that some developers would take this approach as an excuse to not comment their bad code. Another area where I like comments is on documentation comments.  Java has it and so does C# and VB.  It's convenient because we can build automated tools that extract these comments.  These extracted comments are often much better than no documentation at all.  The "go read the code" answer always doesn't fulfill the need for a quick summary of an API. To summarize, I think that the extremes of no comments and too many comments are less than desirable approaches. I prefer documentation comments to explain each class and member (API level) and code comments as necessary to supplement well-written code. Joe
