• BizTalk 2009 - The Community ODBC Adapter: Schema Generation

  - by Stuart Brierley

  Having previously detailed the installation of the Community ODBC Adapter for BizTalk 2009, the next thing I will be looking at is the generation of schemas using this ODBC adapter. Within your BizTalk 2009 project, right click the project and select Add Generated Items.  In the resultant window choose Add Adapter Metadata and click Add to open the Add Adapter Wizard. Check that the BizTalk Server and Database names are correct, select the ODBC adapter and click next. You must now set the connection string. To start with choose set, then new DSN (data source name). You now need to define the Data Source you will be connecting to.  On the User DSN tab select Add add then driver you want to use. In this case I am going to use the MySQL ODBC Driver.  A User DSN will only be visible on the current machine with you as a user. * Although I initially set up a User DSN and this was fine for creating schemas with, I later realised that you actually need a system DSN as the BizTalk host service needs this to be able connect to the database on a receive or send port. You will then be asked to Set up the MySQL ODBC Data Source.  In my case this is a local database making use of named pipes, so I had to make sure that I ticked the "Force use of named pipes" check box and removed the "# The Pipe the MySQL Server will use socket=mysql" line from the mysql.ini; with this is place the connection would fail as there is no apparent way to specify the pipe name in the ODBC driver configuration. This will then update the User DSN tab with the new Data Source.  Make sure that you select it and press OK. Select it again in the Choose Data Source window and press OK.  On the ODBC transport window select next. You will now be presented with the Schema Information window, where you must supply the namespace, type and root element names for your schema. Next choose the type of statement that you will be using to create your schema - in this case I am using a stored procedure. *I later discovered that this option is fine for MySQL stored procedures without input parameters, but failed for MySQL stored procedures with input parameters.  (I will be posting on the way to handle input parameters soon) Next you will need to specify the name of the stored procedure.  In this case I have a simple stored procedure to return all the data held by my TestTable in MySQL. Select * from TestTable; The table itself has three columns: Name, Sex and Married. Selecting finish should now hopefully create your schemas based on the input and output from your stored procedure. In my case I have:   An empty schema for the request; after all I have no parameters for the stored procedure.  A response schema comprised of a Table Record with Name, Sex and Married children. Next I will be looking at the use of the ODBC adpater with: Receive ports Send ports

• Intern Screening - Software 'Quiz'

  - by Jeremy1026

  I am in charge of selecting a new software development intern for a company that I work with. I wanted to throw a little 'quiz' at the applicants before moving forth with interviews so as to weed out the group a little bit to find some people that can demonstrate some skill. I put together the following quiz to send to applicants, it focuses only on PHP, but that is because that is what about 95% of the work will be done in. I'm hoping to get some feedback on A. if its a good idea to send this to applicants and B. if it can be improved upon. # 1. FizzBuzz # Write a small application that does the following: # Counts from 1 to 100 # For multiples of 3 output "Fizz" # For multiples of 5 output "Buzz" # For multiples of 3 and 5 output "FizzBuzz" # For numbers that are not multiples of 3 nor 5 output the number. <?php ?> # 2. Arrays # Create a multi-dimensional array that contains # keys for 'id', 'lot', 'car_model', 'color', 'price'. # Insert three sets of data into the array. <?php ?> # 3. Comparisons # Without executing the code, tell if the expressions # below will return true or false. <?php if ((strpos("a","abcdefg")) == TRUE) echo "True"; else echo "False"; //True or False? if ((012 / 4) == 3) echo "True"; else echo "False"; //True or False? if (strcasecmp("abc","ABC") == 0) echo "True"; else echo "False"; //True or False? ?> # 4. Bug Checking # The code below is flawed. Fix it so that the code # runs properly without producing any Errors, Warnings # or Notices, and returns the proper value. <?php //Determine how many parts are needed to create a 3D pyramid. function find_3d_pyramid($rows) { //Loop through each row. for ($i = 0; $i < $rows; $i++) { $lastRow++; //Append the latest row to the running total. $total = $total + (pow($lastRow,3)); } //Return the total. return $total; } $i = 3; echo "A pyramid consisting of $i rows will have a total of ".find_3d_pyramid($i)." pieces."; ?> # 5. Quick Examples # Create a small example to complete the task # for each of the following problems. # Create an md5 hash of "Hello World"; # Replace all occurances of "_" with "-" in the string "Welcome_to_the_universe." # Get the current date and time, in the following format, YYYY/MM/DD HH:MM:SS AM/PM # Find the sum, average, and median of the following set of numbers. 1, 3, 5, 6, 7, 9, 10. # Randomly roll a six-sided die 5 times. Store the 5 rolls into an array. <?php ?>

• About the K computer

  - by nospam(at)example.com (Joerg Moellenkamp)

  Okay ? after getting yet another mail because of the new #1 on the Top500 list, I want to add some comments from my side: Yes, the system is using SPARC processor. And that is great news for a SPARC fan like me. It is using the SPARC VIIIfx processor from Fujitsu clocked at 2 GHz. No, it isn't the only one. Most people are saying there are two in the Top500 list using SPARC (#77 JAXA and #1 K) but in fact there are three. The Tianhe-1 (#2 on the Top500 list) super computer contains 2048 Galaxy "FT-1000" 1 GHz 8-core processors. Don't know it? The FeiTeng-1000 ? this proc is a 8 core, 8 threads per core, 1 ghz processor made in China. And it's SPARC based. By the way ? this sounds really familiar to me ? perhaps the people just took the opensourced UltraSPARC-T2 design, because some of the parameters sound just to similar. However it looks like that Tianhe-1 is using the SPARCs as input nodes and not as compute notes. No, I don't see it as the next M-series processor. Simple reason: You can't create SMP systems out of them ? it simply hasn't the functionality to do so. Even when there are multiple CPUs on a single board, they are not connected like an SMP/NUMA machine to a shared memory machine ? they are connected with the cluster interconnect (in this case the Tofu interconnect) and work like a large cluster. Yes, it has a lot of oomph in Linpack ? however I assume a lot came from the extensions to the SPARCv9 standard. No, Linpack has no relevance for any commercial workload ? Linpack is such a special load, that even some HPC people are arguing that it isn't really a good benchmark for HPC. It's embarrassingly parallel, it can work with relatively small interconnects compared to the interconnects in SMP systems (however we get in spheres SMP interconnects where a few years ago). Amdahl isn't hitting that hard when running Linpack. Yes, it's a good move to use SPARC. At some time in the last 10 years, there was an interesting twist in perception: SPARC was considered as proprietary architecture and x86 was the open architecture. However it's vice versa ? try to create a x86 clone and you have a lot of intellectual property problems, create a SPARC clone and you have to spend 100 bucks or so to get the specification from the SPARC Foundation and develop your own SPARC processor. Fujitsu is doing this for a long time now. So they had their own processor, their own know-how. So why was SPARC a good choice? Well ? essentially Fujitsu can do what they want with their core as it is their core, for example adding the extensions to the SPARCv9 chipset ? getting Intel to create extensions to x86 to help you with your product is a little bit harder. So Fujitsu could do they needed to do with their processor in order to create such a supercomputer. No, the K is really using no FPGA or GPU as accelerators. The K is really using the CPU at doing this job. Yes, it has a significantly enhanced FPU capable to execute 8 instructions in parallel. No, it doesn't run Solaris. Yes, it uses Linux. No, it doesn't hurt me ... as my colleague Roland Rambau (he knows a lot about HPC) said once to me ... it doesn't matter which OS is staying out of the way of the workload in HPC.

• Blind As a Bat in Multi-Monitor Hell &ndash; Free Program Inside!

  - by ToStringTheory

  If you know me personally, then you probably know that I am going blind thanks to a rare genetic eye disease.  My eye disease has already been a huge detriment to my eyesight.  One of the big things to suffer is my ability to see small things moving fast right in front of me.  On a multi-monitor setup, this makes finding the cursor absolute hell. The Problem I’ll keep this short, as I’ve basically already told you what the problem is.  On my three monitor development computer, I am constantly losing the mouse during the day.  I had used the Microsoft accessibility mousefinder (press CTRL, and it pings around the mouse).  The problem with this is, there is only an effect around 50-100 PX around the mouse, and it is a very light gray, almost unnoticeable.. For someone like me, if I am not looking at the monitor when I click the CTRL button, I have to click it multiple times and dart my eyes back and forth in a futile attempt to catch a glimpse of the action…  I had tried other cursor finders, but none I liked… The Solution So what’s a guy to do when he doesn’t like his options?  MAKE A NEW OPTION…  What else should we as developers do, am I right?  So, I went ahead and made a mousefinder of my own, with 6 separate settings to change the effect.  I am releasing it here for anyone else that may also have problems finding their mouse at times. Some of its features include: Multiple options to change to achieve the exact effect you want. If your mouse moves while it is honing in, it will hone in on its current position. Many times, I would press the button and move my mouse at the same time, and many times, the mouse happened to be at a screen edge, so I would miss it. This program will restart its animation on a new screen if the mouse changes its screen while playing. Tested on Windows 7 x64 Stylish color changing from green to red. Deployed as a ClickOnce, so easy to remove if you don't like it. Press Right CTRL to trigger effect Application lives in notification area so that you can easily reach configuration or close it. To get it to run on startup, copy its application shortcut from its startmenu directory to the “Startup” folder in your startmenu. Conclusion I understand if you don’t download this…  You don’t know me and I don’t know you.  I can only say that I have honestly NOT added any virus’ or malware to the package. Yeah, I know it’s weird Download: ‘ToString(theory) Mousefinder.zip’ CRC32: EEBCE300 MD5: 0394DA581BE6F3371B5BA11A8B24BC91 SHA-1: 2080C4930A2E7D98B81787BB5E19BB24E118991C Finally, if you do use this application - please leave a comment, or email me and tell me what you think of it.

• Property overwrite behaviour

  - by jeremyj

  I thought it worth sharing about property overwrite behaviour because i found it confusing at first in the hope of preventing some learning pain for the uninitiated with MSBuild :-)The confusion for me came because of the redundancy of using a Condition statement in a _project_ level property to test that a property has not been previously set. What i mean is that the following two statements are always identical in behaviour, regardless if the property has been supplied on the command line -  <PropertyGroup>    <PropA Condition=" '$(PropA)' == '' ">PropA set at project level</PropA>  </PropertyGroup>has the same behaviour regardless of command line override as -  <PropertyGroup>     <PropA>PropA set at project level</PropA>   </PropertyGroup>  i.e. the two above property declarations have the same result whether the property is overridden on the command line or not.To prove this experiment with the following .proj file -<?xml version="1.0" encoding="utf-8"?><Project ToolsVersion="4.0" >  <PropertyGroup>    <PropA Condition=" '$(PropA)' == '' ">PropA set at project level</PropA>  </PropertyGroup>  <Target Name="Target1">    <Message Text="PropA: $(PropA)"/>  </Target>  <Target Name="Target2">    <PropertyGroup>      <PropA>PropA set in Target2</PropA>    </PropertyGroup>    <Message Text="PropA: $(PropA)"/>  </Target>  <Target Name="Target3">    <PropertyGroup>      <PropA Condition=" '$(PropA)' == '' ">PropA set in Target3</PropA>    </PropertyGroup>    <Message Text="PropA: $(PropA)"/>  </Target>  <Target Name="Target4">    <PropertyGroup>      <PropA Condition=" '$(PropA)' != '' ">PropA set in Target4</PropA>    </PropertyGroup>    <Message Text="PropA: $(PropA)"/>  </Target></Project>Try invoking it using both of the following invocations and observe its output -1)>msbuild blog.proj /t:Target1;Target2;Target3;Target42)>msbuild blog.proj /t:Target1;Target2;Target3;Target4 "/p:PropA=PropA set on command line"Then try those two invocations with the following three variations of specifying PropA at the project level -1)  <PropertyGroup>     <PropA Condition=" '$(PropA)' == '' ">PropA set at project level</PropA>   </PropertyGroup> 2)   <PropertyGroup>     <PropA>PropA set at project level</PropA>   </PropertyGroup>3)  <PropertyGroup>     <PropA Condition=" '$(PropA)' != '' ">PropA set at project level</PropA>   </PropertyGroup>

• The five steps of business intelligence adoption: where are you?

  - by Red Gate Software BI Tools Team

  When I was in Orlando and New York last month, I spoke to a lot of business intelligence users. What they told me suggested a path of BI adoption. The user’s place on the path depends on the size and sophistication of their organisation. Step 1: A company with a database of customer transactions will often want to examine particular data, like revenue and unit sales over the last period for each product and territory. To do this, they probably use simple SQL queries or stored procedures to produce data on demand. Step 2: The results from step one are saved in an Excel document, so business users can analyse them with filters or pivot tables. Alternatively, SQL Server Reporting Services (SSRS) might be used to generate a report of the SQL query for display on an intranet page. Step 3: If these queries are run frequently, or business users want to explore data from multiple sources more freely, it may become necessary to create a new database structured for analysis rather than CRUD (create, retrieve, update, and delete). For example, data from more than one system — plus external information — may be incorporated into a data warehouse. This can become ‘one source of truth’ for the business’s operational activities. The warehouse will probably have a simple ‘star’ schema, with fact tables representing the measures to be analysed (e.g. unit sales, revenue) and dimension tables defining how this data is aggregated (e.g. by time, region or product). Reports can be generated from the warehouse with Excel, SSRS or other tools. Step 4: Not too long ago, Microsoft introduced an Excel plug-in, PowerPivot, which allows users to bring larger volumes of data into Excel documents and create links between multiple tables.  These BISM Tabular documents can be created by the database owners or other expert Excel users and viewed by anyone with Excel PowerPivot. Sometimes, business users may use PowerPivot to create reports directly from the primary database, bypassing the need for a data warehouse. This can introduce problems when there are misunderstandings of the database structure or no single ‘source of truth’ for key data. Step 5: Steps three or four are often enough to satisfy business intelligence needs, especially if users are sophisticated enough to work with the warehouse in Excel or SSRS. However, sometimes the relationships between data are too complex or the queries which aggregate across periods, regions etc are too slow. In these cases, it can be necessary to formalise how the data is analysed and pre-build some of the aggregations. To do this, a business intelligence professional will typically use SQL Server Analysis Services (SSAS) to create a multidimensional model — or “cube” — that more simply represents key measures and aggregates them across specified dimensions. Step five is where our tool, SSAS Compare, becomes useful, as it helps review and deploy changes from development to production. For us at Red Gate, the primary value of SSAS Compare is to establish a dialog with BI users, so we can develop a portfolio of products that support creation and deployment across a range of report and model types. For example, PowerPivot and the new BISM Tabular model create a potential customer base for tools that extend beyond BI professionals. We’re interested in learning where people are in this story, so we’ve created a six-question survey to find out. Whether you’re at step one or step five, we’d love to know how you use BI so we can decide how to build tools that solve your problems. So if you have a sixty seconds to spare, tell us on the survey!

• Is this Hybrid of Interface / Composition kosher?

  - by paul

  I'm working on a project in which I'm considering using a hybrid of interfaces and composition as a single thing. What I mean by this is having a contain*ee* class be used as a front for functionality implemented in a contain*er* class, where the container exposes the containee as a public property. Example (pseudocode): class Visibility(lambda doShow, lambda doHide, lambda isVisible) public method Show() {...} public method Hide() {...} public property IsVisible public event Shown public event Hidden class SomeClassWithVisibility private member visibility = new Visibility(doShow, doHide, isVisible) public property Visibility with get() = visibility private method doShow() {...} private method doHide() {...} private method isVisible() {...} There are three reasons I'm considering this: The language in which I'm working (F#) has some annoyances w.r.t. implementing interfaces the way I need to (unless I'm missing something) and this will help avoid a lot of boilerplate code. The containee classes could really be considered properties of the container class(es); i.e. there seems to be a fairly strong has-a relationship. The containee classes will likely implement code which would have been pretty much the same when implemented in all the container classes, so why not do it once in one place? In the above example, this would include managing and emitting the Shown/Hidden events. Does anyone see any isseus with this Composiface/Intersition method, or know of a better way? EDIT 2012.07.26 - It seems a little background information is warranted: Where I work, we have a bunch of application front-ends that have limited access to system resources -- they need access to these resources to fully function. To remedy this we have a back-end application that can access the needed resources, with which the front-ends can communicate. (There is an API written for the front-ends for accessing back-end functionality as though it were part of the front-end.) The back-end program is out of date and its functionality is incomplete. It has made the transition from company to company a couple of times and we can't even compile it anymore. So I'm trying to rewrite it in my spare time. I'm trying to update things to make a nice(r) interface/API for the front-ends (while allowing for backwards compatibility with older front-ends), hopefully something full of OOPy goodness. The thing is, I don't want to write the front-end API after I've written pretty much the same code in F# for implementing the back-end; so, what I'm planning on doing is applying attributes to classes/methods/properties that I would like to have code for in the API then generate this code from the F# assembly using reflection. The method outlined in this question is a possible alternative I'm considering instead of implementing straight interfaces on the classes in F# because they're kind of a bear: In order to access something of an interface that has been implemented in a class, you have to explicitly cast an instance of that class to the interface type. This would make things painful when getting calls from the front-ends. If you don't want to have to do this, you have to call out all of the interface's methods/properties again in the class, outside of the interface implementation (which is separate from regular class members), and call the implementation's members. This is basically repeating the same code, which is what I'm trying to avoid!

• Four Easy Ways to Save a Rocky CRM Relationship

  - by Divya Malik

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

• Is the Internet Making us Smarter or Not?

  - by BuckWoody

  I’ve been reading recently about an exchange among some very bright folks, some who posit that the Internet with its instant-on, sometimes-right, big-statement-wins mentality is making people think in a more shallow way, teaching us to rely on others as experts and diluting our logical thought process. Others state that it broadens our perspective and extends our mental reach. Whenever I see this kind of exchange on two ends of a spectrum, I begin to wonder if both sides might be correct.   I can certainly say that I have changed my way of learning, reading, and social interactions because of the Internet. And my tolerance for reading long missives has indeed gone down. I tend to (mentally and literally) “bookmark” things I never seem to have time to get back to. But I also agree that I’ve been exposed to thoughts, ideas and people I never would have encountered any other way. So how to deal with this dichotomy?   Well, I’m going to go off and think about it. No, I’m really going to go off for a full week to a cabin I’ve rented in a National Forest in the Midwest. It has no indoor plumbing, phones, Internet connections or anything else – only a bed to sleep in and a place to cook a little. I’m taking one book, some paper, and a guitar with me and that’s it. I plan to spend my days walking, reading a little, playing a little on the guitar, but mostly just thinking. Those of you who know me might find this unusual. I’m an always-on, hyper-caffeinated, overly-busy, connected person. I haven’t taken a vacation in five years, at least for more than two or three days at a time. Even then, I keep us on the move constantly – our vacations aren’t cruises or anything like that. I check e-mail, post and all that. When I’m not on vacation, I live with and leverage lots of technology, and work with those that do the same. This, however, is a really “unplugged” event, and I’m hoping that it will let me unpack the things I’ve been stuffing in my head. I plan to spend a lot of time on a single subject, writing notes, thinking, and writing more notes.   So after I post tomorrow's “quote of the day” I’ll be “going dark” for a week. No twitter, FaceBook, LinkedIn, e-mail, chat, none of my five blogs will get updated, and I’ll have to turn in my two articles for InformIT.com early. I won’t have access to my college class portal, so my students will be without me for a week. I will really be offline. I’ll see you in a week – hopefully a little more educated. See you then.   Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

• The gestures of Windows 8 (Consumer preview): part 2, More about Search

  - by Laurent Bugnion

  This is part 2 of a multipart blog post about the gestures and shortcuts in Windows 8 consumer preview. Part 1 can be found here! More about the Search charm In the first installment of this series, we talked about the charms and mentioned a few gestures to display the Search charm. Search is a very central and powerful feature in Windows 8, and allows you to search in Apps, Settings, Files and within Metro applications that support the Search contract. There are a few cool features around the Search, and especially the applications associated to it. I already mentioned the keyboard shortcuts you can use: Win-C shows the Charms bar (same as swiping from the right bevel towards the center of the screen). Win-Q open the Search fly out with Apps preselected. Win-W open the Search fly out with Settings preselected. Win-F open the Search fly out with Files preselected. Searching in Metro apps In addition to these three search domains, you can also search a Metro app, as long as it supports the Search contract (check this Build video to learn more about the Search contract). These apps show up in the Search flyout as shown here: Notice the list of apps below the Files button? That’s what we are talking about. First of all, the list order changes when you search in some applications. For instance, in the image above, I had used the Store with the Search charm. This is why the store shows up as the first app. I am not 100% what algorithm is used here (sorting according to number of searches is my guess), but try it out and try to figure it out Applications that have never been searched are sorted alphabetically. Does it mean we will see cool app names like ___AAA_MyCoolApp? I certainly hope not!! Pinning You can also pin often used apps to the Search flyout. To pin an app with the mouse, right click on it in the Search flyout and select Pin from the context menu. With the keyboard, use the arrow keys to go down to the selected app, and then open the context menu. With the finger, simply tap and hold until you see a semi transparent rectangle indicating that the context menu will be shown, then release. The context menu opens up and you can select Pin. Pin context menu Pinned apps Unpinning, Hiding Using the same technique as for pinning here above, you can also unpin a pinned application. Finally, you can also choose to hide an app from the Search flyout altogether. This is a convenient way to clean up and make it easy to find stuff. Note: At this point, I am not sure how to re-add a hidden app to the Search flyout. If anyone knows, please mention it in the comments, thanks! Reordering You can also reorder pinned apps. To do this, with the finger, tap, hold and pull the app to the side, then pull it vertically to reorder it. You can also reorder with the mouse, simply by clicking on an app and pulling it vertically to the place you want to put it. I don’t think there is a way to do that with the keyboard though. That’s it for now More gestures will follow in a next installment! Have fun with Windows 8   Laurent Bugnion (GalaSoft) Subscribe | Twitter | Facebook | Flickr | LinkedIn

• Where should instantiated classes be stored?

  - by Eric C.

  I'm having a bit of a design dilemma here. I'm writing a library that consists of a bunch of template classes that are designed to be used as a base for creating content. For example: public class Template { public string Name {get; set;} public string Description {get; set;} public string Attribute1 {get; set;} public string Attribute2 {get; set;} public Template() { //constructor } public void DoSomething() { //does something } ... } The problem is, not only is the library providing the templates, it will also supply quite a few predefined templates which are instances of these template classes. The question is, where do I put these instances of the templates? The three solutions I've come up with so far are: 1) Provide serialized instances of the templates as files. On the one hand, this solution would keep the instances separated from the library itself, which is nice, but it would also potentially add complexity for the user. Even if we provided methods for loading/deserializing the files, they'd still have to deal with a bunch of files, and some kind of config file so the app knows where to look for those files. Plus, creating the template files would probably require a separate app, so if the user wanted to stick with the files method of storing templates, we'd have to provide some kind of app for creating the template files. Also, this requires external dependencies for testing the templates in the user's code. 2) Add readonly instances to the template class Example: public class Template { public string Name {get; set;} public string Description {get; set;} public string Attribute1 {get; set;} public string Attribute2 {get; set;} public Template PredefinedTemplate { get { Template templateInstance = new Template(); templateInstance.Name = "Some Name"; templateInstance.Description = "A description"; ... return templateInstance; } } public Template() { //constructor } public void DoSomething() { //does something } ... } This method would be convenient for users, as they would be able to access the predefined templates in code directly, and would be able to unit test code that used them. The drawback here is that the predefined templates pollute the Template type namespace with a bunch of extra stuff. I suppose I could put the predefined templates in a different namespace to get around this drawback. The only other problem with this approach is that I'd have to basically duplicate all the namespaces in the library in the predefined namespace (e.g. Templates.SubTemplates and Predefined.Templates.SubTemplates) which would be a pain, and would also make refactoring more difficult. 3) Make the templates abstract classes and make the predefined templates inherit from those classes. For example: public abstract class Template { public string Name {get; set;} public string Description {get; set;} public string Attribute1 {get; set;} public string Attribute2 {get; set;} public Template() { //constructor } public void DoSomething() { //does something } ... } and public class PredefinedTemplate : Template { public PredefinedTemplate() { this.Name = "Some Name"; this.Description = "A description"; this.Attribute1 = "Some Value"; ... } } This solution is pretty similar to #2, but it ends up creating a lot of classes that don't really do anything (none of our predefined templates are currently overriding behavior), and don't have any methods, so I'm not sure how good a practice this is. Has anyone else had any experience with something like this? Is there a best practice of some kind, or a different/better approach that I haven't thought of? I'm kind of banging my head against a wall trying to figure out the best way to go. Thanks!

• CFOs: Do You Have a Playbook for Growth?

  - by Oracle Accelerate for Midsize Companies

  by Jim Lein, Oracle Midsize Programs In most global markets, CFOs are optimistic about their company's growth opportunities. Deloitte's CFO Signals Report, "Time to Accelerate" found that: In the U.K. business optimism is at its highest level in three-and-a-half years Optimism in North America rose from a strong +42% last quarter (Q2 to Q3 2013) to an even stronger +54%. The inaugural Southeast Asia survey, 44% of CFOs reported a positive outlook despite worries over the Chinese economy and political uncertainty. Sustainable and profitable business growth doesn't usually happen by accident. Company's need a playbook for growth that's owned by the CFO. And today, that playbook must leverage the six enabling technologies--Social, Big Data, Mobile, Cloud, Analytics, and The Internet of Things (or, as Oracle president Mark Hurd explains, "The Internet of the People").

• My .NET Technology picks for 2011

  - by shiju

  My Technology predictions for 2011 Cloud computing and Mobile application development will be the hottest trends for 2011. I hope that Windows Azure will be very hot in year 2011 and lot of cloud computing adoption will be happen with Windows Azure on 2011. Web application scalability will be the big challenge for Architects in the next year and architecture approaches like CQRS will get some attention on next year. Architects will look on different options for web application scalability and adoption of NoSQL and Document databases will be more in the year 2011. The following are the my technology picks for .Net stack Windows Azure Windows Azure will be one of the hottest technologies of 2011. Adoption of Cloud and Windows Azure will get big attention on next year. The Windows Azure platform is a flexible cloud–computing platform that lets you focus on solving business problems and addressing customer needs. No need to invest upfront on expensive infrastructure. Pay only for what you use, scale up when you need capacity and pull it back when you don’t. We handle all the patches and maintenance — all in a secure environment with over 99.9% uptime. Silverlight 5 Silverlight is becoming a common technology for variety of development platforms. You can develop Silverlight applications for web, desktop and windows phone. The new Silverlight 5 beta will be available during the starting quarter of the next year with new capabilities and lot of new features. Silverlight 5 will be powerful development platform for both web-based business apps and rich media solutions. We can expect final version of Silverlight 5 on end of 2011. Windows Phone 7 Development Tools Mobile application development will be very hot in year 2011 and Windows Phone 7 will be one of the hottest technologies of next year. You can get introduction on Windows Phone 7 Development Tools from somasegar’s blog post and MSDN documentation available from here. EF Code First I am a big fan of Entity Framework’s Code First approach and hope that Code First approach will attract more people onto Entity Framework 4. EF Code First lets you focus on domain model which will enable Domain-Driven Development for applications. I hope that DDD fans will love the EF Code First approach. The Entity Framework 4 now supports three types of approaches and these will attract different types of developer audience. ASP.NET MVC 3 The ASP.NET MVC 3 will be the hottest technology of Microsoft web stack on the next year. ASP.NET developers will widely move to the ASP.NET MVC Framework from their WebForms development. The new Razor view engine is great and it will increase the adoption of ASP.NET MVC 3. Razor the will improve the productivity when working with ASP.NET MVC 3 Views. You can build great web applications using ASP.NET MVC 3 and jQuery with better maintainability, generation of clean HTML and even better performance. In my opinion, the best technology stack for web development is ASP.NET MVC 3 and Entity Framework 4 Code First as ORM. On the next year, you can expect more articles from my blog on ASP.NET MVC 3 and Entity Framework 4 Code First. RavenDB NoSQL and Document databases will get more attention on the coming year and RavenDB will be the most notable document database in the .NET stack. RavenDB is an Open Source (with a commercial option) document database for the .NET/Windows platform developed by Ayende Rahien. RavenDB is .NET focused document database which comes with a fully functional .NET client API and supports LINQ. I have written few articles on RavenDB and you can read it from here. Managed Extensibility Framework (MEF) Many people didn't realized the power of MEF. The MEF lets you create extensible applications and provides a great solution for the runtime extensibility problem. I hope that .NET developers will more adopt the MEF on the next year for their .NET applications. You can get an excellent introduction on MEF from Anoop Madhusudanan’s blog post MEF or Managed Extensibility Framework – Creating a Zoo and Animals

• BEHIND THE SCENES AT A FLASH-MOB...

  - by OliviaOC

  Today, we interviewed Aarti, who recently organised a flash-mob for Oracle Campus, which you can see on our facebook page Hi Aarti, perhaps you could give us a quick introduction of yourself, and what you do at Oracle? I’ve been with Campus Recruitment for just over a year. I’ve been with Oracle for three years. I was keen to get into the campus role after having watched other colleagues working in campus and when the opportunity arrived I jumped at it. The journey has been fantastic thus far. I’m responsible for the GBU hiring at Oracle. Why did you record the flash-mob video - what were your goals? Flash-mobs were one thing that took off really big in India after the first one in Mumbai. It’s the hot thing in the student community at the moment. A better way to reach out and connect with students. I think that it is also a good way to demonstrate our openness and culture at Oracle – demonstrate that we are very flexible and that we have a cool culture. I knew the video could be shared on our social media pages and reach out to a wider student community What was the preparation and rehearsal for the video like? When I decided to do the video, I had to decide who I would like to do the flash-mob. The new campus hires to Oracle would be ideal for this. We were 2 teams at 2 different locations and Each team took 2-3 songs and choreographed it themselves. Every day at 5pm, each team would meet up and every other weekend the whole group met. Practicing went on for about a month like this. How was the video received by participants and by students on the University campus? The event was well received. We did it during the lunch break at the University so that there was a large presence of students around while the flash mob took place. We set up about an hour beforehand to get everything ready. The break-bell sounded and the students came out, that’s when the flash-mob started. The students were pleasantly surprised that a company was doing this. They also recognised some of the participants involved as former graduates. Since the flash-mob and the video of it that you recorded, have you had much response due to it? We have, especially in the past two weeks. We went back to the college to make some hires. The flash-mob was still fresh in their minds and they knew well who Oracle was as a result. Would you like to repeat this kind of creative initiative again with the recruitment team? Yes, absolutely! I’m over the moon with the flash-mob. My mind is working overtime now with ideas about the next things to do!

• Patterns for a tree of persistent data with multiple storage options?

  - by Robin Winslow

  I have a real-world problem which I'll try to abstract into an illustrative example. So imagine I have data objects in a tree, where parent objects can access children, and children can access parents: // Interfaces interface IParent<TChild> { List<TChild> Children; } interface IChild<TParent> { TParent Parent; } // Classes class Top : IParent<Middle> {} class Middle : IParent<Bottom>, IChild<Top> {} class Bottom : IChild<Middle> {} // Usage var top = new Top(); var middles = top.Children; // List<Middle> foreach (var middle in middles) { var bottoms = middle.Children; // List<Bottom> foreach (var bottom in bottoms) { var middle = bottom.Parent; // Access the parent var top = middle.Parent; // Access the grandparent } } All three data objects have properties that are persisted in two data stores (e.g. a database and a web service), and they need to reflect and synchronise with the stores. Some objects only request from the web service, some only write to it. Data Mapper My favourite pattern for data access is Data Mapper, because it completely separates the data objects themselves from the communication with the data store: class TopMapper { public Top FetchById(int id) { var top = new Top(DataStore.TopDataById(id)); top.Children = MiddleMapper.FetchForTop(Top); return Top; } } class MiddleMapper { public Middle FetchById(int id) { var middle = new Middle(DataStore.MiddleDataById(id)); middle.Parent = TopMapper.FetchForMiddle(middle); middle.Children = BottomMapper.FetchForMiddle(bottom); return middle; } } This way I can have one mapper per data store, and build the object from the mapper I want, and then save it back using the mapper I want. There is a circular reference here, but I guess that's not a problem because most languages can just store memory references to the objects, so there won't actually be infinite data. The problem with this is that every time I want to construct a new Top, Middle or Bottom, it needs to build the entire object tree within that object's Parent or Children property, with all the data store requests and memory usage that that entails. And in real life my tree is much bigger than the one represented here, so that's a problem. Requests in the object In this the objects request their Parents and Children themselves: class Middle { private List<Bottom> _children = null; // cache public List<Bottom> Children { get { _children = _children ?? BottomMapper.FetchForMiddle(this); return _children; } set { BottomMapper.UpdateForMiddle(this, value); _children = value; } } } I think this is an example of the repository pattern. Is that correct? This solution seems neat - the data only gets requested from the data store when you need it, and thereafter it's stored in the object if you want to request it again, avoiding a further request. However, I have two different data sources. There's a database, but there's also a web service, and I need to be able to create an object from the web service and save it back to the database and then request it again from the database and update the web service. This also makes me uneasy because the data objects themselves are no longer ignorant of the data source. We've introduced a new dependency, not to mention a circular dependency, making it harder to test. And the objects now mask their communication with the database. Other solutions Are there any other solutions which could take care of the multiple stores problem but also mean that I don't need to build / request all the data every time?

• Introduction to WebCenter Personalization: &ldquo;The Conductor&rdquo;

  - by Steve Pepper

  There are some new faces in the town of WebCenter with the latest 11g PS3 release.  A new component has introduced itself as "Oracle WebCenter Personalization", a.k.a WCP, to simplify delivery of a personalized experience and content to end users.  This posting reviews one of the primary components within WCP: "The Conductor". The Conductor: This ain't just an ordinary cloud... One of the founding principals behind WebCenter Personalization was to provide an open client-side API that remains independent of the technology invoking it, in addition to independence from the architecture running it.  The Conductor delivers this, and much, much more. The Conductor is the engine behind WebCenter Personalization that allows flow-based documents, called "Scenarios", to be managed and executed on the server-side through a well published and RESTful api.      The Conductor also supports an extensible model for custom provider integration that can be easily invoked within a Scenario to promote seamless integration with existing business assets. Introducing the Scenario Conductor Scenarios are declarative offline-authored documents using the custom Personalization JDeveloper bundle included with WebCenter.  A Scenario contains one (or more) statements that can: Create variables that are scoped to the current execution context Iterate over collections, or loop until a specific condition is met Execute one or more statements when a condition is met Invoke other scenarios that exist within the same namespace Invoke a data provider that integrates with custom applications Once a variable is assigned within the Scenario's execution context, it can be referenced anywhere within the same Scenario using the common Expression Language syntax used in J2EE web containers. Scenarios are then published and tested to the Integrated WebLogic Server domain, or published remotely to other domains running WebCenter Personalization. Various Client-side Models The Conductor server API is built upon RESTful services that support a wide variety of clients able to communicate over HTTP.  The Conductor supports the following client-side models: REST:  Popular browser-based languages can be used to manage and execute Conductor Scenarios.  There are other public methods to retrieve configured provider metadata that can be used by custom applications. The Conductor currently supports XML and JSON for it's API syntax. Java: WebCenter Personalization delivers a robust and light-weight java client with the popular Jersey framework as it's foundation.  It has never been easier to write a remote java client to manage remote RESTful services. Expression Language (EL): Allow the results of Scenario execution to control your user interface or embed personalized content using the session-scoped managed bean.  The EL client can also be used in straight JSP pages with minimal configuration. Extensible Provider Framework The Conductor supports a pluggable provider framework for integrating custom code with Scenario execution.  There are two types of providers supported by the Conductor: Function Provider: Function Providers are simple java annotated classes with static methods that are meant to be served as utilities.  Some common uses would include: object creation or instantiation, data transformation, and the like.  Function Providers can be invoked using the common EL syntax from variable assignments, conditions, and loops. For example:  ${myUtilityClass:doStuff(arg1,arg2))} If you are familiar with EL Functions, Function Providers are based on the same concept. Data Provider: Like Function Providers, Data Providers are annotated java classes, but they must adhere to a much more strict object model.  Data Providers have access to a wealth of Conductor services, such as: Access to namespace-scoped configuration API that can be managed by Oracle Enterprise Manager, Scenario execution context for expression resolution, and more.  Oracle ships with three out-of-the-box data providers that supports integration with: Standardized Content Servers(CMIS),  Federated Profile Properties through the Properties Service, and WebCenter Activity Graph. Useful References If you are looking to immediately get started writing your own application using WebCenter Personalization Services, you will find the following references helpful in getting you on your way: Personalizing WebCenter Applications Authoring Personalized Scenarios in JDeveloper Using Personalization APIs Externally Implementing and Calling Function Providers Implementing and Calling Data Providers

• Microsoft Certifications &ndash; how to prep? and why?

  - by Kelly Jones

  I often get asked by my colleagues, “how do you prepare for Microsoft exams?” Well, the answer for me is a little complicated, so I thought I’d write up here what I do. The first thing I do is go to Microsoft’s website to find the exam that I need to take.  If you’re looking to get a particular certification, then their site lists the exam or exams that you’ll need to pass.  If you’ve already taken an exam, you can log onto the MCP website and use their certification planner.  This little tool tells you what tests you need, based on the exams you’ve already passed.  It is very helpful with the certifications that are multiple tests and especially ones that have electives. Once you’ve identified the test, you can use Microsoft’s website to see the topics that it covers.  This is a good outline to follow when you study.  I’ll keep this handy to reference back throughout my studying to make sure that I’m covering all the topics I need to know. The next step is probably where I am a little different from others.  IF the exam outline covers material that I’ve already been working with, then I’ll skip a lot of the studying and go directly to the practice tests.  However, if I’m looking at the outline and wondering how in the world do you do that? – then it’s time to hit the books. So, where to find study materials?  Try typing in the exam number into any search engine.  You’ll typically find a ton of resources.  If you’re lucky, you’ll find books that others recommend based on their studying and exam experience.  As a Sogeti employee, I have access to three really good resources: an internal company list of all of the consultants who have passed particular tests (on our Connex website), Books 24x7, and Transcender practice exams. Once my studying is done (either through books or experience), I’ll go through the practice exams.  I find them really helpful in getting my knowledge lined up to the thinking process that the exam writers use.  If I’m relying on my experience, then this really helps me to identify gaps in my knowledge that I’ll need to fill. That’s about it.  If I’m doing ok on the practice exams, then I’ll take the real thing.  I’ve found that the practice exams are usually more difficult than then real thing. Oh – one other thing I do related to Microsoft exams – I try to take any beta exams that Microsoft makes available that fall into my skill set.  Microsoft has started a blog to announce these and the seats usually fill up really quick.  The blog is at http://blogs.technet.com/betaexams/ . You don’t get your results instantly, like a normal exam, instead you have to wait for everyone to finish taking the beta exams and for Microsoft to determine which questions they are using and which they are dropping.  So, be prepared to wait six to eight weeks for your results.

• Consolidation in a Database Cloud

  - by B R Clouse

  Consolidation of multiple databases onto a shared infrastructure is the next step after Standardization.  The potential consolidation density is a function of the extent to which the infrastructure is shared.  The three models provide increasing degrees of sharing: Server: each database is deployed in a dedicated VM. Hardware is shared, but most of the software infrastructure is not. Standardization is often applied incompletely since operating environments can be moved as-is onto the shared platform. The potential for VM sprawl is an additional downside. Database: multiple database instances are deployed on a shared software / hardware infrastructure. This model is very efficient and easily implemented with the features in the Oracle Database and supporting products. Many customers have moved to this model and achieved significant, measurable benefits. Schema: multiple schemas are deployed within a single database instance. The most efficient model, it places constraints on the environment. Usually this model will be implemented only by customers deploying their own applications.  (Note that a single deployment can combine Database and Schema consolidations.) Customer value: lower costs, better system utilization In this phase of the maturity model, under-utilized hardware can be used to host more workloads, or retired and those workloads migrated to consolidation platforms. Customers benefit from higher utilization of the hardware resources, resulting in reduced data center floor space, and lower power and cooling costs. And, the OpEx savings from Standardization are multiplied, since there are fewer physical components (both hardware and software) to manage. Customer value: higher productivity The OpEx benefits from Standardization are compounded since not only are there fewer types of things to manage, now there are fewer entities to manage. In this phase, customers discover that their IT staff has time to move away from "day-to-day" tasks and start investing in higher value activities. Database users benefit from consolidating onto shared infrastructures by relieving themselves of the requirement to maintain their own dedicated servers. Also, if the shared infrastructure offers capabilities such as High Availability / Disaster Recovery, which are often beyond the budget and skillset of a standalone database environment, then moving to the consolidation platform can provide access to those capabilities, resulting in less downtime. Capabilities / Characteristics In this phase, customers will typically deploy fixed-size clusters and consolidate on a cluster until that cluster is deemed "full," at which point a new cluster is built. Customers will define one or a few cluster architectures that are used wherever possible; occasionally there may be deployments which must be handled as exceptions. The "full" policy may be based on number of databases deployed on the cluster, or observed peak workload, etc. IT will own the provisioning of new databases on a cluster, making the decision of when and where to place new workloads. Resources may be managed dynamically, e.g., as a priority workload increases, it may be given more CPU and memory to handle the spike. Users will be charged at a fixed, relatively coarse level; or in some cases, no charging will be applied. Activities / Tasks Oracle offers several tools to plan a successful consolidation. Real Application Testing (RAT) has a feature to help plan and validate database consolidations. Enterprise Manager 12c's Cloud Management Pack for Database includes a planning module. Looking ahead, customers should start planning for the Services phase by defining the Service Catalog that will be made available for database services.

• Where are my date ranges in Analytics coming from?

  - by Jeffrey McDaniel

  In the P6 Reporting Database there are two main tables to consider when viewing time - W_DAY_D and W_Calendar_FS.  W_DAY_D is populated internally during the ETL process and will provide a row for every day in the given time range. Each row will contain aspects of that day such as calendar year, month, week, quarter, etc. to allow it to be used in the time element when creating requests in Analytics to group data into these time granularities. W_Calendar_FS is used for calculations such as spreads, but is also based on the same set date range. The min and max day_dt (W_DAY_D) and daydate (W_Calendar_FS) will be related to the date range defined, which is a start date and a rolling interval plus a certain range. Generally start date plus 3 years.  In P6 Reporting Database 2.0 this date range was defined in the Configuration utility.  As of P6 Reporting Database 3.0, with the introduction of the Extended Schema this date range is set in the P6 web application. The Extended Schema uses this date range to calculate the data for near real time reporting in P6.  This same date range is validated and used for the P6 Reporting Database.  The rolling date range means if today is April 1, 2010 and the rolling interval is set to three years, the min date will be 1/1/2010 and the max date will be 4/1/2013.  1/1/2010 will be the min date because we always back fill to the beginning of the year. On April 2nd, the Extended schema services are run and the date range is adjusted there to move the max date forward to 4/2/2013.  When the ETL process is run the Reporting Database will pick up this change and also adjust the max date on the W_DAY_D and W_Calendar_FS. There are scenarios where date ranges affecting areas like resource limit may not be adjusted until a change occurs to cause a recalculation, but based on general system usage these dates in these tables will progress forward with the rolling intervals. Choosing a large date range can have an effect on the ETL process for the P6 Reporting Database. The extract portion of the process will pull spread data over into the STAR. The date range defines how long activity and resource assignment spread data is spread out in these tables. If an activity lasts 5 days it will have 5 days of spread data. If a project lasts 5 years, and the date range is 3 years the spread data after that 3 year date range will be bucketed into the last day in the date range. For the overall project and even the activity level you will still see the correct total values.  You just would not be able to see the daily spread 5 years from now. This is an important question when choosing your date range, do you really need to see spread data down to the day 5 years in the future?  Generally this amount of granularity years in the future is not needed. Remember all those values 5, 10, 15, 20 years in the future are still available to report on they would be in more of a summary format on the activity or project.  The data is always there, the level of granularity is the decision.

• Failed to unmount partitions

  - by msknapp

  I'm trying to install ubuntu from a pen drive. I have windows 7 installed already and want to keep that installation. I have a 3TB drive that has one 2TB partition on it, so the last 1TB is completely unused, which is where I want to install ubuntu. I started ubuntu in "try ubuntu" mode and then opened gparted, and then deleted the unused partition for the last third of my drive, then tried to install ubuntu. During the install, it asked me if I wanted to unmount the drives I already have The installer has detected that the following disks have mounted partitions: /dev/sda, /dev/sdb Do you want the installer to try to unmount the partitions on these disks before continuing? If you leave them mounted, you will not be able to create, delete, or resize partitions on these disks, but you may be able to install to existing partitions there. No, Yes I said no because I don't want to lose my windows 7 installation, nor any of that data. I wonder, if I had said yes above, would I have lost all the data on those drives? Anyways, I hit no and continued. I chose to install ubuntu alongside windows 7, and hit continue. A few minutes passed when this popup appeared: Failed to unmount partitions The installer needs to commit changes to partition tables, but cannot do so because the partitions on the following mount points could not be unmounted: /media/ubuntu/Three\ Terabyte Drive Terabyte\ DriveDrive Please close any applications using these mount points. Would you like the installer to try to unmount these partitions again? Go Back, Continue Why is this not working? What am I supposed to do? ========== Update: I went ahead and said yes, it can unmount those partitions. It finished installing Ubuntu, but now when i start my machine it just takes me to the grub rescue prompt. Seems like it broke something.

• Writing a method to 'transform' an immutable object: how should I approach this?

  - by Prog

  (While this question has to do with a concrete coding dilemma, it's mostly about what's the best way to design a function.) I'm writing a method that should take two Color objects, and gradually transform the first Color into the second one, creating an animation. The method will be in a utility class. My problem is that Color is an immutable object. That means that I can't do color.setRGB or color.setBlue inside a loop in the method. What I can do, is instantiate a new Color and return it from the method. But then I won't be able to gradually change the color. So I thought of three possible solutions: 1- The client code includes the method call inside a loop. For example: int duration = 1500; // duration of the animation in milliseconds int steps = 20; // how many 'cycles' the animation will take for(int i=0; i<steps; i++) color = transformColor(color, targetColor, duration, steps); And the method would look like this: Color transformColor(Color original, Color target, int duration, int steps){ int redDiff = target.getRed() - original.getRed(); int redAddition = redDiff / steps; int newRed = original.getRed() + redAddition; // same for green and blue .. Thread.sleep(duration / STEPS); // exception handling omitted return new Color(newRed, newGreen, newBlue); } The disadvantage of this approach is that the client code has to "do part of the method's job" and include a for loop. The method doesn't do it's work entirely on it's own, which I don't like. 2- Make a mutable Color subclass with methods such as setRed, and pass objects of this class into transformColor. Then it could look something like this: void transformColor(MutableColor original, Color target, int duration){ final int STEPS = 20; int redDiff = target.getRed() - original.getRed(); int redAddition = redDiff / steps; int newRed = original.getRed() + redAddition; // same for green and blue .. for(int i=0; i<STEPS; i++){ original.setRed(original.getRed() + redAddition); // same for green and blue .. Thread.sleep(duration / STEPS); // exception handling omitted } } Then the calling code would usually look something like this: // The method will usually transform colors of JComponents JComponent someComponent = ... ; // setting the Color in JComponent to be a MutableColor Color mutableColor = new MutableColor(someComponent.getForeground()); someComponent.setForeground(mutableColor); // later, transforming the Color in the JComponent transformColor((MutableColor)someComponent.getForeground(), new Color(200,100,150), 2000); The disadvantage is - the need to create a new class MutableColor, and also the need to do casting. 3- Pass into the method the actual mutable object that holds the color. Then the method could do object.setColor or similar every iteration of the loop. Two disadvantages: A- Not so elegant. Passing in the object that holds the color just to transform the color feels unnatural. B- While most of the time this method will be used to transform colors inside JComponent objects, other kinds of objects may have colors too. So the method would need to be overloaded to receive other types, or receive Objects and have instanceof checks inside.. Not optimal. Right now I think I like solution #2 the most, than solution #1 and solution #3 the least. However I'd like to hear your opinions and suggestions regarding this.

The M2M platform has taken over as one of the industry’s main buzz words and there is no question as to why! Just 5 months ago we had a guest post on “Machine to Machine – The Internet of Things – It’s about the Data.” Now companies are extending the use of M2M data to increase opportunity and intelligence across the Enterprise. Just this week, Oracle announced the results of its “Designing an M2M Platform for the Connected World” research, examining the evolving drivers behind ‘Machine to Machine’ (M2M) projects and how those changes are impacting solution requirements.

• Red Meat's Music is Rare - and Well Done

  - by Oracle OpenWorld Blog Team

  By Karen Shamban The blogger has questions; San Francisco-based country band Red Meat has answers. Although we forgot to ask how they got their band name, dang it. Read on and enjoy the honesty and insight. Q. What do you like best about performing in front of a live audience?A. Probably just having fun and entertaining the audience. We've been together for almost two decades, and in that time we've played for crowds of five people, and for crowds of more than 15,000. Both are equally important to us, and just as fun. We turn Jill and Smelley loose on the between-songs repartee, and let the songs shine through. On the best night, we feed on the audience's love and vice-versa. It's emotional vampirism of the best sort. [Blogger's note: now that whole "red meat" thing is starting to make sense ...] Q. Do you prefer smaller, intimate venues or larger, louder ones? Why?A. We love both. Whether it's a chance to connect with a small room or huge audience, we always try to hit 'em between the eyes! Q. What about your fans surprises you?A. Since we've been together for so long, we're pretty much on our third generation of fans now. We're excited that the Bakersfield sound has that same effect on the new, younger fans as it did on the punk rockers that we played to 20 years ago. And we still see them at our shows too! Q. What about your live act surprises your fans?A. For people who haven't seen Red Meat before, they may be dragged to a show thinking they don't like country music. But they're surprised to hear it done in a way that excites them so much. We get a lot of first-timers coming up to us after a performance and asking, "Wait, THAT'S what country music can sound like?" Q. There are going to be a lot of technical people (you could call them geeks) in the Oracle crowd - what are they going to love about your performance?A. Just what everyone loves about a Red Meat show - the chance to drink beer, dance, get rowdy, and have a great time. Q. Have you been on tour recently? If so, what do you like about touring, and what do you dislike?A. Actually, we're going to be coming off the road immediately into the Oracle OpenWorld Music Festival, having just played some Texas dates. On tour, we love playing for fans who don't get to see us as often as our California fans do. And food. Most of our conversations in the van center around food. Q. Ever think about playing another kind of music? If so, what, and why?A. Our tastes and influences in the band run all over the place. Obviously we love the Bakersfield artists - Buck Owens, Merle Haggard, Dwight Yoakam - but we love other types of roots music as well, along with the Beatles, NRBQ, MC5, punk/new wave, and countless bar bands that we've had the privilege of playing with through the years. But as far as playing a different kind of music as Red Meat? Nah. We love what we're doing. Q. What are the top three things people should know about your music?A1. Country music, done right, has unlimited soul.A2. Red Meat is a modern band, playing original material, with a great debt to the Bakersfield sound of Buck Owens and Merle Haggard.A3. It's FUN. More details on the Festival and the band: Oracle OpenWorld Music Festival Red Meat

• Collaborative Organizations build Organizational Culture

  “A Collaborative organization builds its culture based on the idea of the family or an athletic team.”(Hoefling, 2001) As I grew up, I participated in many different types of clubs, civic organizations, and sports teams.  Now looking back at the more successful undertakings, I can see three commonalities amongst them. They all shared a defined purpose or goal, defined functional roles, and a shared sense of responsibility to the group. Defined Purpose or Goal In order to unit people to work together, they must share a common goal or have a common purpose. An example of this would be the Lions Club International Foundation. There purpose is to help everyone to lead healthier and more productive lives, nurtures the potential of youth, promotes health, serves the elderly, empowers the disabled and helps victims of disasters. This organization holds localized meetings across the world and works in conjunction with other localized clubs within there organization along with other organizations to promote common goals. If there are no common goals for the group, then there is nothing that binds people to the group, and nothing will be done. Defined Functional Roles In order for an organization to work and function as a team, they must have defined roles and everyone must know how their roles are interdependent on each other. Lets shed light on this subject by looking at a football team’s offense.  Each player has an assigned role to play each time the ball is snapped. The offensive line blocks for the running back or quarterback, the quarterback passes the ball to the wide receiver or hands it off to the running back and the running back and wide receivers run with the ball towards the goal line. Each member of this team shares a common goal of scoring a touchdown, but if each team member does not fulfill their assigned roles the offences will collapse and the team will lose yards. This will provide a set back to the teams goal of scoring a touchdown because they potential are then farther away from the goal line.  In addition, if all the players do not know their roles and how they are part of a larger team then even larger yard losses can occur. Shared Sense of Personal Responsibility to the Group Shared responsibility comes with the shared common goals. Each person in the organization must do their part to promote the common shared goal or purpose based on their abilities. A prime example of this is a wrestling team competing in a match. Points are awarded to the team based on how many wins the team achieves in the meet and of that how many wins where won by decision or by pin. If a wrestler pins his opponent the teams will receive 2 points for the win, but if the wrestler wins by decision, then the team only gets one point for the win. So it is the responsibility of each person on the team to not get pinned if they are unable to win the match. If the team member gets pinned then the other team receives an additional point for the win. References: Hoefling, T. (2001).
