• Group / User based security. Table / SQL question

  - by Brett

  Hi, I'm setting up a group / user based security system. I have 4 tables as follows: user groups group_user_mappings acl where acl is the mapping between an item_id and either a group or a user. The way I've done the acl table, I have 3 columns of note (actually 4th one as an auto-id, but that is irrelevant) col 1 item_id (item to access) col 3 user_id (user that is allowed to access) col 3 group_id (group that is allowed to access) So for example item1, peter, , item2, , group1 item3, jane, , so either the acl will give access to a user or a group. Any one line in the ACL table with either have an item - user mapping, or an item group. If I want to have a query that returns all objects a user has access to, I think I need to have a SQL query with a UNION, because I need 2 separate queries that join like.. item - acl - group - user AND item - acl - user This I guess will work OK. Is this how its normally done? Am I doing this the right way? Seems a little messy. I was thinking I could get around it by creating a single user group for each person, so I only ever deal with groups in my SQL, but this seems a little messy as well..

• Help me write my LISP :) LISP environments, Ruby Hashes...

  - by MikeC8

  I'm implementing a rudimentary version of LISP in Ruby just in order to familiarize myself with some concepts. I'm basing my implementation off of Peter Norvig's Lispy (http://norvig.com/lispy.html). There's something I'm missing here though, and I'd appreciate some help... He subclasses Python's dict as follows: class Env(dict): "An environment: a dict of {'var':val} pairs, with an outer Env." def __init__(self, parms=(), args=(), outer=None): self.update(zip(parms,args)) self.outer = outer def find(self, var): "Find the innermost Env where var appears." return self if var in self else self.outer.find(var) He then goes on to explain why he does this rather than just using a dict. However, for some reason, his explanation keeps passing in through my eyes and out through the back of my head. Why not use a dict, and then inside the eval function, when a new "sub-environment" needs to be created, just take the existing dict and update the key/value pairs that need to be updated, and pass that new dict into the next eval? Won't the Python interpreter keep track of the previous "outer" envs? And won't the nature of the recursion ensure that the values are pulled out from "inner" to "outer"? I'm using Ruby, and I tried to implement things this way. Something's not working though, and it might be because of this, or perhaps not. Here's my eval function, env being a regular Hash: def eval(x, env = $global_env) ........ elsif x[0] == "lambda" then ->(*args) { eval(x[2], env.merge(Hash[*x[1].zip(args).flatten(1)])) } ........ end The line that matters of course is the "lambda" one. If there is a difference, what's importantly different between what I'm doing here and what Norvig did with his Env class? If there's no difference, then perhaps someone can enlighten me as to why Norvig uses the Env class. Thanks :)

• JQuery autocomplete problem

  - by heffaklump

  Im using JQuerys Autocomplete plugin, but it doesn't autocomplete upon entering anything. Any ideas why it doesnt work? The basic example works, but not mine. var ppl = {"ppl":[{"name":"peterpeter", "work":"student"}, {"name":"piotr","work":"student"}]}; var options = { matchContains: true, // So we can search inside string too minChars: 2, // this sets autocomplete to begin from X characters dataType: 'json', parse: function(data) { var parsed = []; data = data.ppl; for (var i = 0; i < data.length; i++) { parsed[parsed.length] = { data: data[i], // the entire JSON entry value: data[i].name, // the default display value result: data[i].name // to populate the input element }; } return parsed; }, // To format the data returned by the autocompleter for display formatItem: function(item) { return item.name; } }; $('#inputplace').autocomplete(ppl, options); Ok. Updated: <input type="text" id="inputplace" /> So, when entering for example "peter" in the input field. No autocomplete suggestions appear. It should give "peterpeter" but nothing happens. And one more thing. Using this example works perfectly. var data = "Core Selectors Attributes Traversing Manipulation CSS Events Effects Ajax Utilities".split(" "); $("#inputplace").autocomplete(data);

• DDD: Enum like entities

  - by Chris

  Hi all, I have the following DB model: **Person table** ID | Name | StateId ------------------------------ 1 Joe 1 2 Peter 1 3 John 2 **State table** ID | Desc ------------------------------ 1 Working 2 Vacation and domain model would be (simplified): public class Person { public int Id { get; } public string Name { get; set; } public State State { get; set; } } public class State { private int id; public string Name { get; set; } } The state might be used in the domain logic e.g.: if(person.State == State.Working) // some logic So from my understanding, the State acts like a value object which is used for domain logic checks. But it also needs to be present in the DB model to represent a clean ERM. So state might be extended to: public class State { private int id; public string Name { get; set; } public static State New {get {return new State([hardCodedIdHere?], [hardCodeNameHere?]);}} } But using this approach the name of the state would be hardcoded into the domain. Do you know what I mean? Is there a standard approach for such a thing? From my point of view what I am trying to do is using an object (which is persisted from the ERM design perspective) as a sort of value object within my domain. What do you think? Question update: Probably my question wasn't clear enough. What I need to know is, how I would use an entity (like the State example) that is stored in a database within my domain logic. To avoid things like: if(person.State.Id == State.Working.Id) // some logic or if(person.State.Id == WORKING_ID) // some logic

• Excessive use of Inner Join for more than 3 tables

  - by Archangel08

  Good Day, I have 4 tables on my DB (not the actual name but almost similar) which are the ff: employee,education,employment_history,referrence employee_id is the name of the foreign key from employee table. Here's the example (not actual) data: **Employee** ID Name Birthday Gender Email 1 John Smith 08-15-2014 Male [email protected] 2 Jane Doe 00-00-0000 Female [email protected] 3 John Doe 00-00-0000 Male [email protected] **Education** Employee_ID Primary Secondary Vocation 1 Westside School Westshore H.S SouthernBay College 2 Eastside School Eastshore H.S NorthernBay College 3 Northern School SouthernShore H.S WesternBay College **Employment_History** Employee_ID WorkOne StartDate Enddate 1 StarBean Cafe 12-31-2012 01-01-2013 2 Coffebucks Cafe 11-01-2012 11-02-2012 3 Latte Cafe 01-02-2013 04-05-2013 Referrence Employee_ID ReferrenceOne Address Contact 1 Abraham Lincoln Lincoln Memorial 0000000000 2 Frankie N. Stein Thunder St. 0000000000 3 Peter D. Pan Neverland Ave. 0000000000 NOTE: I've only included few columns though the rest are part of the query. And below are the codes I've been working on for 3 consecutive days: $sql=mysql_query("SELECT emp.id,emp.name,emp.birthday,emp.pob,emp.gender,emp.civil,emp.email,emp.contact,emp.address,emp.paddress,emp.citizenship,educ.employee_id,educ.elementary,educ.egrad,educ.highschool,educ.hgrad,educ.vocational,educ.vgrad,ems.employee_id,ems.workOne,ems.estartDate,ems.eendDate,ems.workTwo,ems.wstartDate,ems.wendDate,ems.workThree,ems.hstartDate,ems.hendDate FROM employee AS emp INNER JOIN education AS educ ON educ.employee_id='emp.id' INNER JOIN employment_history AS ems ON ems.employee_id='emp.id' INNER JOIN referrence AS ref ON ref.employee_id='emp.id' WHERE emp.id='$id'"); Is it okay to use INNER JOIN this way? Or should I modify my query to get the results that I wanted? I've also tried to use LEFT JOIN but still it doesn't return anything .I didn't know where did I go wrong. You see, as I have thought, I've been using the INNER JOIN in correct manner, (since it was placed before the WHILE CLAUSE). So I couldn't think of what could've possible went wrong. Do you guys have a suggestion? Thanks in advance.

• encapsulation in python list (want to use " instead of ')

  - by Codehai

  I have a list of users users["pirates"] and they're stored in the format ['pirate1','pirate2']. If I hand the list over to a def and query for it in MongoDB, it returns data based on the first index (e.g. pirate1) only. If I hand over a list in the format ["pirate1","pirate"], it returns data based on all the elements in the list. So I think there's something wrong with the encapsulation of the elements in the list. My question: can I change the encapsulation from ' to " without replacing every ' on every element with a loop manually? Short Example: aList = list() # get pirate Stuff # users["pirates"] is a list returned by a former query # so e.g. users["pirates"][0] may be peter without any quotes for pirate in users["pirates"]: aList.append(pirate) aVar = pirateDef(aList) print(aVar) the definition: def pirateDef(inputList = list()): # prepare query col = mongoConnect().MYCOL # query for pirates Arrrr pirates = col.find({ "_id" : {"$in" : inputList}} ).sort("_id",1).limit(50) # loop over users userList = list() for person in pirates: # do stuff that has nothing to do with the problem # append user to userlist userList.append(person) return userList If the given list has ' encapsulation it returns: 'pirates': [{'pirate': 'Arrr', '_id': 'blabla'}] If capsulated with " it returns: 'pirates' : [{'_id': 'blabla', 'pirate' : 'Arrr'}, {'_id': 'blabla2', 'pirate' : 'cheers'}] EDIT: I tried figuring out, that the problem has to be in the MongoDB query. The list is handed over to the Def correctly, but after querying pirates only consists of 1 element... Thanks for helping me Codehai

• Union of two or more (hash)maps

  - by javierfp

  I have two Maps that contain the same type of Objects: Map<String, TaskJSO> a = new HashMap<String, TaskJSO>(); Map<String, TaskJSO> b = new HashMap<String, TaskJSO>(); public class TaskJSO { String id; } The map keys are the "id" properties. a.put(taskJSO.getId(), taskJSO); I want to obtain a list with: all values in "Map b" + all values in "Map a" that are not in "Map b". What is the fastest way of doing this operation? Thanks EDIT: The comparaison is done by id. So, two TaskJSOs are considered as equal if they have the same id (equals method is overrided). My intention is to know which is the fastest way of doing this operation from a performance point of view. For instance, is there any difference if I do the "comparaison" in a map (as suggested by Peter): Map<String, TaskJSO> ab = new HashMap<String, TaskJSO>(a); ab.putAll(b); ab.values() or if instead I use a set (as suggested by Nishant): Set s = new Hashset(); s.addAll(a.values()); s.addAll(b.values());

• SQLSaturday 33 Observations

  - by Geoff N. Hiten

  Along with a lot of my colleagues, I went to SQLSaturday #33 in Charlotte this last weekend.  Overall a really good event, especially for a first-time organizer.  There is some controversy over certain events where my name got mentioned so I thought I would clear the air. Before I get to the core controversy, let's get the details out of the way.  The Microsoft Offices in Charlotte were an excellent venue for this event.  I really appreciated the Microsoft employees that helped out by letting us in and out of normally secure areas.  This is definitely above and beyond on their part. Thanks to the organizers (especially Greg and Peter) for the great hospitality they showed to the speakers.  Now for the specifics.  Like most events of this type, there was a raffle at the end for some cool swag.  As a speaker I got raffle tickets just like any other attendee.  The raffle was clearly promoted as "must be present to win".  The problem is that for various reasons, the raffle kicked off immediately after the last speaker finished in the largest room.  That room was across the parking lot from all the other rooms for the event.  I happened to have one of the last sessions of the day, and not in the main room.  I also ran long since the audience was very interactive and there were a lot of follow-up questions.  (BTW, thanks to everyone who came and stayed for my session.  Sorry it cost you the chance to win too.).  My name was drawn for an very nice piece of swag (iPod Touch if you insist).  Since I wasn't there, I didn't win. Several folks mentioned I was still speaking and was "here" (as in at the event) just not "here in the room". Yes, I was mad when I found out about it. I think that was handled poorly.  I personally lost out as did my audience (dunno if anyone specific lost anything, but it is the idea that counts).  It was a mistake. Mistakes happen.  Nobody acted maliciously.  Heck, the guys running the event who made the decision are my friends and remain so.  I got over my mad.  We talked about this privately and we are all OK with what happened.  I am not going to let a gadget get in the way of a couple of good friendships. I think the mistake was mostly due to a lack of unity between the venue buildings   Pam Shaw had a similar challenge in Tampa a few weeks ago, including a speaker who ran long on the last session (not me that time).  She had a couple of teenage volunteers to act as gofers/runners.  They counted heads in sessions, pointed people to last-minute room and session changes, and generally helped connect the organizers to what was actually happening.  Note that this was not Pam's first SQLSaturday event.  She knew but the knowledge had not been institutionalized.  We (The SQL community in general and SQLSaturday organizers in particular) now know how essential gofers are to success. I know I spent most of this post focusing on the controversy, but I wanted to clear everything up.  I don't want to let a minor mistake, made in good faith, overshadow what was a tremendously good event for the community. As for the iPod Touch, someone in the SQL community is enjoying it, so it is not a total loss.  And if losing out on it is the price I pay so we can learn this, then that is what a community leader does.  Consider it a gift.  Besides, I really wanted a Zune 120 :)

• WebCenter Customer Spotlight: Texas Industries, Inc.

  - by me

  Author: Peter Reiser - Social Business Evangelist, Oracle WebCenter  Solution SummaryTexas Industries, Inc. (TXI) is a leading supplier of cement, aggregate, and consumer product building materials for residential, commercial, and public works projects. TXI is based in Dallas and employs around 2,000 employees. The customer had the challenge of decentralized and manual processes for entering 180,000 vendor invoices annually.  Invoice entry was a time- and resource-intensive process that entailed significant personnel requirements. TXI implemented a centralized solution leveraging Oracle WebCenter Imaging, a smart routing solution that enables users to capture invoices electronically with Oracle WebCenter Capture and Oracle WebCenter Forms Recognition to send  the invoices through to Oracle Financials for approvals and processing.  TXI significantly lowered resource needs for payable processing,  increase productivity by 80% and reduce invoice processing cycle times by 84%—from 20 to 30 days to just 3 to 5 days, on average. Company OverviewTexas Industries, Inc. (TXI) is a leading supplier of cement, aggregate, and consumer product building materials for residential, commercial, and public works projects. With operating subsidiaries in six states, TXI is the largest producer of cement in Texas and a major producer in California. TXI is a major supplier of stone, sand, gravel, and expanded shale and clay products, and one of the largest producers of bagged cement and concrete  products in the Southwest. Business ChallengesTXI had the challenge of decentralized and manual processes for entering 180,000 vendor invoices annually.  Invoice entry was a time- and resource-intensive process that entailed significant personnel requirements. Their business objectives were: Increase the efficiency of core business processes, such as invoice processing, to support the organization’s desire to maintain its role as the Southwest’s leader in delivering high-quality, low-cost products to the construction industry Meet the audit and regulatory requirements for achieving Sarbanes-Oxley (SOX) compliance Streamline entry of 180,000 invoices annually to accelerate processing, reduce errors, cut invoice storage and routing costs, and increase visibility into payables liabilities Solution DeployedTXI replaced a resource-intensive, paper-based, decentralized process for invoice entry with a centralized solution leveraging Oracle WebCenter Imaging 11g. They worked with the Oracle Partner Keste LLC to develop a smart routing solution that enables users to capture invoices electronically with Oracle WebCenter Capture and then uses Oracle WebCenter Forms Recognition and the Oracle WebCenter Imaging workflow to send the invoices through to Oracle Financials for approvals and processing. Business Results Significantly lowered resource needs for payable processing through centralization and improved efficiency  Enabled the company to process invoices faster and pay bills earlier, allowing it to take advantage of additional vendor discounts Tracked to increase productivity by 80% and reduce invoice processing cycle times by 84%—from 20 to 30 days to just 3 to 5 days, on average Achieved a 25% reduction in paper invoice storage costs now that invoices are captured digitally, and enabled a 50% reduction in shipping costs, as the company no longer has to send paper invoices between headquarters and production facilities for approvals “Entering and manually processing more than 180,000 vendor invoices annually was time and labor intensive. With Oracle Imaging and Process Management, we have automated and centralized invoice entry and processing at our corporate office, improving productivity by 80% and reducing invoice processing cycle times by 84%—a very important efficiency gain.” Terry Marshall, Vice President of Information Services, Texas Industries, Inc.

• 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!

• Handling null values and missing object properties in Silverlight 4

  - by PeterTweed

  Before Silverlight 4 to bind a data object to the UI and display a message associated with either a null value or if the binding path was wrong, you would need to write a Converter.  In Silverlight 4 we find the addition of the markup extensions TargetNullValue and FallbackValue that allows us to display a value when a null value is found in the bound to property and display a value when the property being bound to is not found. This post will show you how to use both markup extensions. Steps: 1. Create a new Silverlight 4 application 2. In the body of the MainPage.xaml.cs file replace the MainPage class with the following code:     public partial class MainPage : UserControl     {         public MainPage()         {             InitializeComponent();             this.Loaded += new RoutedEventHandler(MainPage_Loaded);         }           void MainPage_Loaded(object sender, RoutedEventArgs e)         {             person p = new person() { NameValue = "Peter Tweed" };             this.DataContext = p;         }     }       public class person     {         public string NameValue { get; set; }         public string TitleValue { get; set; }     } This code defines a class called person with two properties.  A new instance of the class is created, only defining the value for one of the properties and bound to the DataContext of the page. 3.  In the MainPage.xaml file copy the following XAML into the LayoutRoot grid:         <Grid.RowDefinitions>             <RowDefinition Height="60*" />             <RowDefinition Height="28*" />             <RowDefinition Height="28*" />             <RowDefinition Height="30*" />             <RowDefinition Height="154*" />         </Grid.RowDefinitions>         <Grid.ColumnDefinitions>             <ColumnDefinition Width="86*" />             <ColumnDefinition Width="314*" />         </Grid.ColumnDefinitions>         <TextBlock Grid.Row="1" Height="23" HorizontalAlignment="Left" Margin="32,0,0,0" Name="textBlock1" Text="Name Value:" VerticalAlignment="Top" />         <TextBlock Grid.Row="2" Height="23" HorizontalAlignment="Left" Margin="32,0,0,0" Name="textBlock2" Text="Title Value:" VerticalAlignment="Top" />         <TextBlock Grid.Row="3" Height="23" HorizontalAlignment="Left" Margin="32,0,0,0" Name="textBlock3" Text="Non Existant Value:" VerticalAlignment="Top" />         <TextBlock Grid.Column="1" Grid.Row="1" Height="23" HorizontalAlignment="Left" Name="textBlock4" Text="{Binding NameValue, TargetNullValue='No Name!!!!!!!'}" VerticalAlignment="Top" Margin="6,0,0,0" />         <TextBlock Grid.Column="1" Grid.Row="2" Height="23" HorizontalAlignment="Left" Name="textBlock5" Text="{Binding TitleValue, TargetNullValue='No Title!!!!!!!'}" VerticalAlignment="Top" Margin="6,0,0,0" />         <TextBlock Grid.Column="1" Grid.Row="3" Height="23" HorizontalAlignment="Left" Margin="6,0,0,0" Name="textBlock6" Text="{Binding AgeValue, FallbackValue='No such property!'}" VerticalAlignment="Top" />    This XAML defines three textblocks – two of which use the TargetNull and one that uses the FallbackValue markup extensions.  4. Run the application and see the person name displayed as defined for the person object, the expected string displayed for the TargetNullValue when no value exists for the boudn property and the expected string displayed for the FallbackValue when the property bound to is not found on the bound object. It's that easy!

• 2014 Conferences - JFokus, JavaLand & GeeCon!

  - by Heather VanCura

  There has been a delay in publishing these past event summaries from early 2014--JFokus in February, JavaLand in March, and GeeCon in May. As we plan for Devoxx UK next week, I found these summaries that did not make it past 'draft' stage.  We had some great successes with the first three events of 2014, a Java developer conference trifecta! Participation topics included Java, the JCP program overall and the Adopt-a-JSR programs.   First up in February was JFokus in Stockholm. The energy and talent in Stockholm is amazing and the conference organizers do a stellar job running it and welcoming the speakers of this event.  I enjoyed the city walk and speaker dinner, as well as many opportunities to interact with conference speakers and attendees, both during and after the conference hours. Reza Rehman invited me to speak during his Java EE 7 lab session about the Adopt-a-JSR program, and I gave a quickie session on the JCP and Adopt-a-JSR.  There was also a late night Birds of a Feather (BoF) session held jointly with Cecelia Borg, Martijn Verburg and Reza Rehman.  This was an interactive conversation with a focus on the Java EE community survey results and encouraging more community participation and collaboration in Java development.  The Java 8 keynote by Georges Saab and Mark Reinhold was also very entertaining,  I was sorry to miss FOSDEM happening the previous weekend this year in Brussels, but I hope to attend in 2015.  Favorite take home gift -- Lambdas cap! In March, the inaugural version of the JavaLand conference happened inside Phantasialand, an amusement park in Germany. Markus Eisele suggested having an Early Adopters area at the conference, which I was keen to implement. In 2013 at Devoxx Belgium we held some activities in the Hackergaren area around Lambdas and Java EE 7, so this was a great opportunity to expand on a more interactive conference format and Andreas Badelt from the program committee helped in the planning for this area.  Daniel Bryant and Mani Sarkar from the London Java Community led some general Adopt-a-JSR discussions and AdoptOpen JDK activities.  JCP Spec Leads, Anatole Tresch from Credit Suisse, leading JSR 354, Money & Currency API, and Ed Burns from Oracle, leading JSR 344, JavaServer Faces 2.2, attended to engage with conference attendees on their JSRs.  Favorite - Stephen Chin's roller coaster video. In May, GeeCon in Krakow was anther awesome conference!  The conference organizers were warm and welcoming and I enjoyed time getting to know the other speakers at the event. There was a JCP and Adopt-a-JSR participation session as well as a moderated panel session on Early Adopters.  We had an amazing panel -- Daniel Bryant, Arun Gupta, Tomasz Borek , and Peter Lawrey. The panel discussed the Adopt-a-JSR and Adopt OpenJDK program, and how the participants work together to get involved and contribute to both the Java SE and Java EE platforms.  If was an interesting discussion and sparked some new ideas on how Java User Groups in Poland and around the world can contribute in a significant and meaningful way to create better and more practical Java standards today and in the future.  Favorite take home gift - GeeCon mug!   These were some of the highlights of the events--looking forward to Devoxx UK next week.  I will publish these details tomorrow!

• ArchBeat Link-o-Rama Top 10 for December 9-15, 2012

  - by Bob Rhubart

  You click, we listen. The following list reflects the Top 10 most popular items posted on the OTN ArchBeat Facefbook page for the week of December 9-15, 2012. DevOps Basics II: What is Listening on Open Ports and Files – WebLogic Essentials | Dr. Frank Munz "Can you easily find out which WebLogic servers are listening to which port numbers and addresses?" asks Dr. Frank Munz. The good doctor has an answer—and a tech tip. Using OBIEE against Transactional Schemas Part 4: Complex Dimensions | Stewart Bryson "Another important entity for reporting in the Customer Tracking application is the Contact entity," says Stewart Bryson. "At first glance, it might seem that we should simply build another dimension called Dim – Contact, and use analyses to combine our Customer and Contact dimensions along with our Activity fact table to analyze Customer and Contact behavior." SOA 11g Technology Adapters – ECID Propagation | Greg Mally "Many SOA Suite 11g deployments include the use of the technology adapters for various activities including integration with FTP, database, and files to name a few," says Oracle Fusion Middleware A-Team member Greg Mally. "Although the integrations with these adapters are easy and feature rich, there can be some challenges from the operations perspective." Greg's post focuses on technical tips for dealing with one of these challenges. Podcast: DevOps and Continuous Integration In Part 1 of a 3-part program, panelists Tim Hall (Senior Director of product management for Oracle Enterprise Repository and Oracle’s Application Integration Architecture), Robert Wunderlich (Principal Product Manager for Oracle’s Application Integration Architecture Foundation Pack) and Peter Belknap (Director of product management for Oracle SOA Integration) discuss why DevOps matters and how it changes development methodologies and organizational structure. Good To Know - Conflicting View Objects and Shared Entity | Andrejus Baranovskis Oracle ACE Director Andrejus Baranovskis shares his thoughts -- and a sample application -- dealing with an "interesting ADF behavior" encountered over the weekend. Cloud Deployment Models | B. R. Clouse Looking out for the cloud newbies... "As the cloud paradigm grows in depth and breadth, more readers are approaching the topic for the first time, or from a new perspective," says B. R. Clouse. "This blog is a basic review of cloud deployment models, to help orient newcomers and neophytes." Service governance morphs into cloud API management | David Linthicum "When building and using clouds, the ability to manage APIs or services is the single most important item you can provide to ensure the success of the project," says David Linthicum. "But most organizations driving a cloud project for the first time have no experience handling a service-based architecture and don't see the need for API management until after deployment. By then, it's too late." Oracle Fusion Middleware Security: Password Policy in OAM 11g R2 | Rob Otto Rob Otto continues the Oracle Fusion Middleware A-Team "Oracle Access Manager Academy" series with a detailed look at OAM's ability to support "a subset of password management processes without the need to use Oracle Identity Manager and LDAP Sync." Understanding the JSF Lifecycle and ADF Optimized Lifecycle | Steven Davelaar Could you call that a surprise ending? Oracle WebCenter & ADF Architecture Team (A-Team) member learned a lot more than he expected while creating a UKOUG presentation entitled "What you need to know about JSF to be succesful with ADF." Expanding on requestaudit - Tracing who is doing what...and for how long | Kyle Hatlestad "One of the most helpful tracing sections in WebCenter Content (and one that is on by default) is the requestaudit tracing," says Oracle Fusion Middleware A-Team architect Kyle Hatlestad. Get up close and technical in his post. Thought for the Day "There is no code so big, twisted, or complex that maintenance can't make it worse." — Gerald Weinberg Source: SoftwareQuotes.com

• Are Chief Digital Officers the Result of CMO/CIO Refusal to Change?

  - by Mike Stiles

  Apparently CDO no longer just stands for “Collateralized Debt Obligations.”  It stands for Chief Digital Officer. And they’re the ones who are supposed to answer the bat signal CEO’s are throwing into the sky, swoop in and POW! drive the transition of the enterprise to integrated digital systems. So imagine being a CMO or a CIO at such an enterprise and realizing it’s been determined that you are not the answer that’s needed. In fact, IntelligentHQ author Ashley Friedlein points out the very rise of the CDO is an admission of C-Suite failure to become savvy enough, quickly enough in modern technology. Is that fair? Despite the repeated drumbeat that CMO’s and CIO’s must enter a new era of cooperation and collaboration to enact the social-enabled enterprise, the verdict seems to be that if it’s happening at all, it’s not happening fast enough. Therefore, someone else is needed with the authority to make things happen. So who is this relatively new beast? Gartner VP David Willis says, “The Chief Digital Officer plays in the place where the enterprise meets the customer, where the revenue is generated, and the mission accomplished.” In other words, where the rubber meets the road. They aren’t just another “C” heading up a unit. They’re the CEO’s personal SWAT team, able to call the shots necessary across all units to affect what has become job one…customer experience. And what are the CMO’s and CIO’s doing while this is going on? Playing corporate games. Accenture reports 38% of CMOs say IT deliberately keeps them out of the loop, with 35% saying marketing’s needs aren’t a very high priority. 31% of CIOs say marketers don’t understand tech and regularly go around them for solutions. Fun! Meanwhile the CEO feels the need to bring in a parental figure to pull it all together. Gartner thinks 25% of all orgs will have a CDO by 2015 as CMO’s and particularly CIO’s (Peter Hinssen points out many CDO’s are coming “from anywhere but IT”) let the opportunity to be the agent of change their company needs slip away. Perhaps most interestingly, these CDO’s seem to be entering the picture already on the fast track. One consultancy counted 7 instances of a CDO moving into the CEO role, which, as this Wired article points out, is pretty astounding since nobody ever heard of the job a few years ago. And vendors are quickly figuring out that this is the person they need to be talking to inside the brand. The position isn’t without its critics. Forrester’s Martin Gill says the reaction from executives at some traditional companies to someone being brought in to be in charge of digital might be to wash their own hands of responsibility for all things digital – a risky maneuver given the pervasiveness of digital in business. They might not even be called Chief Digital Officers. They might be the Chief Customer Officer, Chief Experience Officer, etc. You can call them Twinkletoes if you want to, but essentially anyone who has the mandate direct from the CEO to enact modern technology changes not currently being championed by the CMO or CIO can be regarded as “boss.” @mikestiles @oraclesocialPhoto: freedigitalphotos.net

• Where Twitter Stands Heading Into 2013

  - by Mike Stiles

  As Twitter continued throughout 2012 to be a stage on which global politics and culture played itself out, the company itself underwent some adjustments that give us a good indication of what users and brands can expect from the platform in 2013. The power of the network did anything but fade. Celebrities continued to use it to connect one-on-one. Even the Pope signed on this year. It continued to fuel revolutions. It played an exponentially large factor in this US Presidential election. And around the world, the freedom to speak was challenged as users were fired, sued, sometimes even jailed for their tweets. Expect more of the same in 2013, as Twitter has entrenched itself, for individuals, causes and brands, as the fastest, easiest, most efficient way to message the masses so some measure of impact can come from it. It’s changed everything, and it’s not finished. These fun facts reveal the position of strength with which Twitter enters 2013: It now generates a billion tweets every 2.5 days It has 500 million+ users The average Twitter user has tweeted 307 times 32% of everyone using the Internet uses Twitter It’s expected to bring in $540 million in ad revenue by 2014 11 new accounts are created every second High-level Executive Summary: people love it, people use it, and they’re going to keep loving and using it. Whether or not outside developers love it is a different matter. 2012 marked a shift from welcoming the third party support that played at least some role in Twitter being so warmly embraced, to discouraging anything that replicates what Twitter can do itself…or plans to do itself. It’s not the open playground it once was. Now Twitter must spend 2013 proving it can innovate in-house and keep us just as entranced. Likewise, Twitter is distancing itself from Facebook. Images from the #1 platform’s Instagram don’t work on Twitter anymore, and Twitter’s rolling out their own photo filter product. Where the two have lived in a “plenty of room for everybody” symbiosis up to now, 2013 could see the giants ramping up a full-on rivalry. Twitter is exhibiting a deliberate strategy. Updates have centered on more visually appealing search results, and making finding and sharing content easier. Deals have been cut with some media entities so their content stands out. CEO Dick Costolo has said tweets aren’t the attraction, they’re what leads you to content. Twitter aims to be a key distributor of media and info. Add the addition of former News Corp. President Peter Chernin to the board, and their hashtag landing page experience for events, and their media behemoth ambitions get pretty clear. There are challenges ahead and Costolo has also laid those out; entry into China, figuring out how to have Twitter deliver both comprehensive and relevant, targeted experiences, and the visualization of big data. What does this mean for corporations? They can expect a more media-rich evolution and growing emphases on imagery. They can expect more opportunities to create great media content and leverage Twitter for its distribution. And they can expect new ways to surface in searches. Are brands diving in? 56% of customer tweets to companies get completely and totally ignored. Ugh. A study Twitter recently conducted with Compete shows people who see tweets from retailers are more likely to buy a product. And, the more retailer tweets they see, the more likely they are to purchase on the retail site. As more of those tweets point to engaging media content from the brand, the results should get even better. Twitter appears ready for 2013. Enterprise brands have some work to do. @mikestilesPhoto Stuart Miles, freedigitalphotos.net
