• Help assigning product id for e-commerce site? [closed]

  - by Stanford Sequeira

  I am starting an e-commerce marketplace. I am new to e-commerce, but I am taking it up as a challenge. I will have multiple vendors on my site and they will upload their products through CSV files for bulk upload. However there will be certain popular products already listed in the database, they can add those to their listing (like Amazon for 3rd party sellers). I have no idea how to assign product codes for every product, can you help me out? I'm talking about something like Amazon's ASIN number. Or may be is it possible to let vendors assign their own numbers? How does that work?

• Innovative SPARC: Lighting a Fire Under Oracle's New Hardware Business

  - by Paulo Folgado

  "There's a certain level of things you can do with commercially available parts," says Oracle Executive Vice President Mike Splain. But, he notes, you can do so much more if you design the parts yourself. Mike Splain,EVP, OracleYou can, for example, design cryptographic accelerators into your microprocessors so customers can run their networks fully encrypted if they choose.Of course, it helps if you've already built multiple processing "cores" into those chips so they can handle all that encrypting and decrypting while still getting their other work done.System on a ChipAs the leader of Oracle Microelectronics, Mike knows how implementing clever innovations in silicon can give systems a real competitive advantage.The SPARC microprocessors that his team designed at Sun pioneered the concept of multiple cores several years ago, and the UltraSPARC T2 processor--the industry's first "system on a chip"--packs up to eight cores per chip, each running as many as eight threads at once. That's the most cores and threads of any general-purpose processor. Looking back, Mike points out that the real value of large enterprise-class servers was their ability to run a lot of very large applications in parallel."The beauty of our CMT [chip multi-threading] machines is you can get that same kind of parallel-processing capability at a much lower cost and in a much smaller footprint," he says.The Whole StackWhat has Mike excited these days is that suddenly the opportunity to innovate is much bigger as part of Oracle."In my group, we used to look up the software stack and say, 'We can do any innovation we want, provided the only thing we have to change is what's in the Solaris operating system'--or maybe Java," he says. "If we wanted to change things beyond that, we'd have to go outside the walls of Sun and we'd have to convince the vendors: 'You have to align with us, you have to test with us, you have to build for us, and then you'll reap the benefits.' Now we get access to the entire stack. We can look all the way through the stack and say, 'Okay, what would make the database go faster? What would make the middleware go faster?'"Changing the WorldMike and his microelectronics team also like the fact that Oracle is not just any software company. We're #1 in database, middleware, business intelligence, and more."We're like all the other engineers from Sun; we believe we can change the world, if we can just figure out how to get people to pay attention to us," he says. "Now there's a mechanism at Oracle--much more so than we ever had at Sun."He notes, too, that every innovation in SPARC has involved some combination of hardware and softwareoptimization."Take our cryptography framework, for example. Sure, we can accelerate rapidly, but the Solaris OS has to provide the right set of interfaces that applications can tap into," Mike says. "Same thing with our multicore architecture. We have to have software that can utilize all those threads and run in parallel." His engineers, he points out, have never been interested in producing chips that sell as mere components."Our chips are always designed to go into systems and be combined with various pieces of software," he says. "Our job is to enable the creation of systems."

  In this Issue: Loek van den Ouweland, Colin Eberhardt, Rudi Grobler, Joost van Schaik, Mike Taulty(-2-, -3-), Deborah Kurata, David Kelley, Peter Foot, Samuel Jack(-2-), and WindowsPhoneGeek(-2-). Above the Fold: Silverlight: "Silverlight Simple MVVM Commanding" Deborah Kurata WP7: "WP7 CustomInputPrompt control with Cancel button" WindowsPhoneGeek Expression Blend: "Silverlight Templated Image Button with two images" Loek van den Ouweland Shoutouts: Dave Campbell posted a write-up about the project he's on and the use of Sterling: Sterling Object-Oriented Database for ISO 1.0 Released!... Also see Jeremy Likness' post on the 1.0 release: Sterling Object-Oriented Database 1.0 RTM Not necessarily Silverlight, but darn cool, a great control by Sasha Barber: WPF : A Weird 3d based control snoutholder announced new content: Windows Phone 7 QuickStarts Live! From SilverlightCream.com: Silverlight Templated Image Button with two images Loek van den Ouweland has a video tutorial up for creating an ImageButton with a hover state... Expression Blend coolness, and check out the external links he has to their training site. Windows Phone 7 Performance Measurements – Emulator vs. Hardware Colin Eberhardt's latest is a popular post comparing performance metrics between the WP7 emulator and a real device. Mileage may vary, but I'm pretty sure the overall results are conculsive, and should help the way you view your app as you're building in the emulator. WP7: WebClient vs HttpWebRequest Rudi Grobler's latest is a discussion of WebClient and HttpWebRequest, gives coding examples of each plus discussion of why you may choose one over the other... and pay attention to his comment about mobile providers. A Blendable Windows Phone 7 / Silverlight clipping behavior Joost van Schaik posted this WP7/Silverlight clipping behavior he developed because all the other solutions were not blendable. Another really useful piece of code from Joost! Blend Bits 22–Being Stylish Mike Taulty has 3 more episodes in his Blend Bits series... first up is on one Styles... explicit, implicit, inheriting... you name it, he's covering it! Blend Bits 23–Templating Part 1 MIke Taulty then has the beginning of a series within his Blend Bits series on Templating. This is something you just have to either bite the bullet and go with Blend to do, or consume someone else's work. Mike shows us how to do it ourself by tweaking the visual aspects of a checkbox Blend Bits 24–Templating Part 2 In part 2 of the Templating series, Mike Taulty digs deeper into Blend and cracks open the Listbox control to take a bunch of the inner elements out for a spin... fun stuff and great tutorial, Mike! Silverlight Simple MVVM Commanding Deborah Kurata has another great MVVM post up... if you don't have your head wrapped around commanding yet, this is a good place to start that process... VB and C# as always. App Development for Windows Phone 7 101 David Kelley goes through the basics of producing a WP7 app both from the Silverlight and XNA side... good info and good external links to get you going. Copyable TextBlock for Windows Phone Peter Foot takes a look at the Copy/Paste functionality in WP7 and how to apply it to a TextBlock... which is NOT an out-of-the-box solution. How to deploy to, and debug, multiple instances of the Windows Phone 7 emulator Samuel Jack has a couple posts up this week... first is this clever one on running multiple copies of the emulator at once... too cool for debugging a multi-player game! Multi-player enabling my Windows Phone 7 game: Day 3 – The Server Side Samuel Jack's latest is a detailed look at his day 3 adventure of taking his multi-player game to WP7... lots of information and external links... what do you say, give him another day? :) WP7 CustomInputPrompt control with Cancel button WindowsPhoneGeek has a couple more posts up... first is this "CustomInputPrompt" control based off the InputPrompt from Coding4Fun. Implementing Windows Phone 7 DataTemplateSelector and CustomDataTemplateSelector In his latest post, WindowsPhoneGeek writes a DataTemplateSelector to allow different data templates for different list elements based on the type of the element.

• PHP find first of occurrence of string

  - by mike

  I have a string of data like below and I've been struggling trying to figure out how to split it up so that I can use it efficiently. "United States FirstName: Mike LastName: Wolf City: Chicago" I need to split up the string in to substrings and the list may not always be in the same order. For example it could vary like below: "United States City: Chicago FirstName: Mike LastName: Wolf" "United States FirstName: City: Chicago Mike LastName: Wolf" I need to find which parameter comes first after 'United States'. It could be 'City:', 'FirstName:' or 'LastName:'. And, I also need to know the start position of the first parameter. Thanks in advance!

• Podcast Show Notes: Evolving Enterprise Architecture

  - by Bob Rhubart

  The latest series of ArchBeat podcast programs grew out of another virtual meet-up, held on March 11. As with previous meet-ups, I sent out a general invitation to the roster of previous ArchBeat panelists to join me on Skype to talk about whatever topic comes up. For this event, Oracle ACE Directors Mike van Alst and Jordan Braunstein  showed up, along with Oracle product manager Jeff Davies.  The result was an impressive and wide-ranging discussion on the evolution of Enterprise Architecture, the role of technology in EA, the impact of social computing, and challenge of having three generations of IT people at work in the enterprise – each with different perspectives on technology. Mike, Jordan, and Jeff talked for more than an hour, and the conversation was so good that slicing and dicing it to meet the time constraints for these podcasts has been a challenge. The first two segments of the conversation are now available. Listen to Part 1 Listen to Part 2 Part 3 will go live next week, and an unprecedented fourth segment will follow. These guys have strong opinions, and while there is common ground, they don’t always agree. But isn’t that what a community is all about? I suspect that you’ll have questions and comments after listening, so I encourage you to reach out to Mike, Jordan, and Jeff  via the following links: Mike van Alst Blog | Twitter | LinkedIn | Business |Oracle Mix | Oracle ACE Profile Jordan Braunstein Blog | Twitter | LinkedIn | Business | Oracle Mix | Oracle ACE Profile Jeff Davies Homepage | Blog | LinkedIn | Oracle Mix (Also check out Jeff’s book: The Definitive Guide to SOA: Oracle Service Bus)   Coming Soon ArchBeat’s microphones were there for the panel discussions at the recent Oracle Technology Network Architect Days in Dallas and Anaheim. Excerpts from those conversations will be available soon.

  For those of you that remember the old Mike Myers SNL skit, talk amongst yourselves..I’ll give you a topic: This is purely based on 1 conversation with 1 person from the mothership (Microsoft). SQL 11 is in the works and supposedly includes readable mirrors and in the version beyond that read/write mirrors. Given the name I would assume that release would be (drum roll) 2011 some time.

• Natural Language parsing of an appointment?

  - by Mike Hugo

  I'm looking for a Java library to help parse user entered text that represents an 'appointment' for a calendar application. For instance: Lunch with Mike at 11:30 on Tuesday or 5pm Happy hour on Friday I've found some promising leads like https://jchronic.dev.java.net/ and http://www.datejs.com/ which can parse dates - but I also need to be able to extract the title of the event like "Lunch with Mike". If such an API doesn't exist, I'm also interested in any thoughts on how best to approach the problem from a coding perspective.

  Hi, I just upgraded to Maverick, and now I can't change my theme except for the cursor and window border/decoration. I've just reinstalled the themes I want to use (Dust + Dust extra) successfully, and while the window border/decorations change properly when I select them, nothing else changes. The icon set doesn't change; gnome-panel doesn't change. I'm stuck on the fugly fallback theme - the one you see when you do gksudo gedit or something. Halp! -Mike

• adding mongo to path

  - by Mike

  Bit of a noob question. I have downloaded MongoDb and installed it here /Users/mike/downloads/mongodb In order to start it, I then have to 'cd' into the 'bin' /Users/mike/downloads/mongodb/bin and run ./mongod (to start the database) and ./mongo (to start the mongo shell) The problem is that I can only work with python and ruby scripts using the mongo shell if I have those scripts stored in the same bin directory, and I don't think that's the ideal set up. Will exporting the path allow me to access mongo from outside the bin? For example, I would prefer to have my ruby scripts in /sites/ruby and be able to access mongo by starting ruby in /sites/ruby. If exporting to path is the solution, how do I do that. I'm using a mac

• Lucene - querying with long strings

  - by Mikos

  I have an index, with a field "Affiliation", some example values are: "Stanford University School of Medicine, Palo Alto, CA USA", "Institute of Neurobiology, School of Medicine, Stanford University, Palo Alto, CA", "School of Medicine, Harvard University, Boston MA", "Brigham & Women's, Harvard University School of Medicine, Boston, MA" "Harvard University, Cambridge MA" and so on... (the bottom-line being the affiliations are written in multiple ways with no apparent consistency) I query the index on the affiliation field using say "School of Medicine, Stanford University, Palo Alto, CA" (with QueryParser) to find all Stanford related documents, I get a lot of false +ves, presumably because of the presence of School of Medicine etc. etc. (note: I cannot use Phrase query because of variability in the way affiliation is constructed) I have tried the following: Use a SpanNearQuery by splitting the search phrase with a whitespace (here I get no results!) Tried boosting (using ^) by splitting with the comma and boosting the last parts such as "Palo Alto CA" with a much higher boost than the initial phrases. Here I still get lots of false +ves. Any suggestions on how to approach this? If SpanNearQuery the way to go, Any ideas on why I get 0 results?

• Is this error caused by a 64-bit library being accessed by a Java program running in a 32-bit JVM?

  - by Mike

  I'm trying to create a simple Java app that uses JNI to call some native functions. I've followed the examples in the JNI Programming Guide and can't seem to get them to work. I have the following Hello World program, written in Java: class HelloWorld { private native void print(); public static void main(String [] args) { new HelloWorld().print(); } static { System.load("/home/mike/Desktop/libHelloWorld.so"); } } I compile it using javac HelloWorld.java, just like normal. Then I run javah -jni HelloWorld, and finally the following: gcc34 -shared -fpic -o libHelloWorld.so -I/<path to JDK>/include -I/<path to JDK>/include/linux HelloWorld.c gcc34 is the name of the GCC program on my machine here at work (I don't control that) and I obviously place the real path to the JDK in that command. When I run my program, using the standard java HelloWorld, I get an error saying the following: Exception in thread "main" java.lang.UnsatisfiedLinkError: /home/mike/Desktop/libHelloWorld.so: /home/mike/Desktop/libHelloWorld.so: wrong ELF class: ELFCLASS64 (Possible causes: architecture word width mismatch) at java.lang.ClassLoader$NativeLibrary.load(Native Method) at java.lang.ClassLoader.loadLibrary0(ClassLoader.java:1778) at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1674) at java.lang.Runtime.load0(Runtime.java:770) at java.lang.System.load(System.java:1003) at HelloWorld.<clinit>(HelloWorld.java:8) Could not find the main class: HelloWorld. Program will exit. I know I'm running a 32-bit JVM (and unfortunately, as of right now, I'm not allowed to get a 64-bit JVM). I tried telling GCC to compile in 32-bit mode using the "-m32" option, but we don't have (and again, can't get) what we need for that. Does this sound like a 32/64-bit conflict or something else?

  In this Issue: Carlos Figueira(-2-), Subodh Pushpak, Gergely Orosz, John Papa, Mike Snow(-2-), Rishi, Tim Heuer, Stefan Olson, and David Anson. Shoutouts: Josh Holmes blogged about a cool app the City of Miami has up: Miami 311: Built on Windows Azure Gergely Orosz reports on the state of a bug he found pre SL4: Silverlight 4 still displays large elements incorrectly Laura Foy and Charlie Kindel discuss WP7 on Channel 9: Windows Phone 7 Developer Tools Refresh Announced Charlie Kindel has an announcement, good instructions, and what's new notes on the Windows Phone Developer Tools CTP Refresh! Tim Heuer mentioned the workaround for this in his post (below), but I thought you might like to read Brandon Watson's debrief of what it's all about: Signed Assemblies Bug in the Windows Phone Tools CTP Refresh Laurent Bugnion posted about interrelations between versions of Blend and WP7 code... read it closely: Be careful when installing the Blend Windows Phone 7 Add-In From SilverlightCream.com: Consuming REST/POX services in Silverlight 4 Carlos Figueira has a pair of posts up about consuming services in Silverlight 4. This first one is about consuming REST/POX services. He provides a Service Contract that can be used with either and the full project code is available as well. Consuming REST/JSON services in Silverlight 4 In the second post, Carlos Figueira provides the code to allow WCF and Silverlight 4 to consume strongly-typed REST/JSON... and again, all the code is available. Silverlight and WCF caching Subodh Pushpak has a post up discussing caching in WCF, and has code demonstrating turning caching on at run-time. Detecting Silverlight Version Installed Gergely Orosz said it right when he said "Detecting the Silverlight version installed on a client machine isn’t entirely straightforward." ... and after reading this post, if you take the link to his ScottLogic blog, you'll get a full break-out of how it's done. Silverlight TV 22: Tim Heuer on Extending the SMF It's Thursday, and that means Silverlight TV! ... this week, John Papa has on Tim Heuer who has always been out there pushing media... and he's talking about SMF or Silverlight Media Framework for the uninitiated, and also extending it. Silverlight Tip of the Day #7 – Localized Resources Mike Snow has Tip Number 7 up and it's about localization... good end-to-end discussion and demonstration. Just thought I should use that to prove to my daughter that the tatoo she had put on the back of her neck actually reads "Eat More Broccoli" :) Silverlight Tip of the Day #8 – Detecting Alt, Shift, Control, Window & Apple Keys Combinations I just realized Mike Snow's site logo reads "Silverlight Tips of the Day" (bolding mine) ... that answers why I'm seeing more than one -- sorry Mike, couldn't pass it up :) ... Mike's second tip today and number 8 in the series is on detecting all the mouse button and ctl/alt/shift combinations in Silverlight. nRoute: More Wholesomeness, with SL 4 and .NET 4.0 Rishi has a post up announcing a new nRoute release for Silverlight 4 and .NET 4.0 He's tweaked the code to take advantages of enhancements in the new platforms, so check it out. Windows Phone 7 Developer Tools April 2010 Refresh Booya... Tim Heuer announced the release of the next drop in the WP7 tools ... dang wish I was at home today :) ... be sure to read the post for info such as the notes about Authenticode Assemblies and the release notes. Updates to Silverlight Multi-binding support Stefan Olson points up a SL4 change to Multi-binding support that he had previously blogged about. He shows the previous non-working example, and what you have to do to make it work now. Using XAML to create a custom wallpaper image for your mobile device David Anson has a solution for those pesky lost devices, and let me go on the record right now saying if anyone finds a WP7 phone laying around, just call me, it's mine :) [think that'd work??] ... ok, David's solution is a WPF app "MobileDeviceHomeScreenMaker" that you get the info set and it produces a png you then put on your device. But seriously about that lost phone... Stay in the 'Light!

• Oracle BI and XS Energy Drinks – Don’t Miss the Amway Presentation!

  - by Michelle Kimihira

  By Maria Forney Amway is a global leader in the direct sales industry with $10.9B in annual sales in more than 100 countries and territories. The company has implemented a global BI framework that provides accurate, consistent, and timely insights to support global, regional and local analytical research, business planning, performance measurement and assessment. Oracle BI EE is used by 1500 employees across Amway sales, marketing, finance, and supply chain business units as well as Amway affiliates in Europe, Russia, South Africa, Japan, Australia, Latin America, Malaysia, Vietnam, and Indonesia. Last week, I spoke with Lead Data Analyst with Amway Global Sales, Dan Arganbright, and IT Manager with Amway BI Competency Center, Mike Olson, about their upcoming presentation at Oracle OpenWorld in San Francisco. Scheduled during a prime speaking slot on Monday, October 1 at 12:15pm in Moscone West, 2007, Dan and Mike will discuss their experience building Amway’s Distributor Consulting solution, powered by Oracle BI EE. You can find more information here. As background, Amway offers people an opportunity to own their own businesses and consumers exclusive products in health and wellness, beauty and home care.  The Amway internal Sales organization is charged with consulting leadership-level Distributors to help them with data insights and ultimately grow their business. Until recently, this was a resource-intense process of gathering and formatting data. In some markets, it took over 40 hours to collect the data and produce the analysis needed for one consultation session. Amway began its global BI journey in 2006 and since then the company has migrated from having multiple technology providers and integration points to an integrated strategic vendor approach. Today, the company has standardized on Oracle technology for BI.  Amway has achieved cost savings through the retirement of redundant technology platforms. In addition, Mike’s organization has led the charge to align disparate BI organizations into a BI Competency Center.  The following diagram highlights the simplicity of the standardized architecture of Amway today. Dubbed Distributor Consulting, Amway has developed a BI solution using the Oracle technology stack to help Distributor leaders grow their businesses. The Distributor Consulting solution provides over 40 metrics for Sales staff to provide data-driven insights on the Distributors and organizations they support.  Using Oracle BI EE, Exadata, and Oracle Data Integrator, Amway provides customized and personalized business intelligence, and the Oracle BI EE dashboards were developed by the Amway Sales organization, which demonstrates business empowerment of the technology. Amway is also leveraging the power of BI to drive business growth in all of its markets.  A new set of Distributor Segmentation metrics are enabling a better understanding of distributor behaviors. A Global Scorecard that Amway developed provides key metrics at a market and global level for executive-level discussions. Product Analysis teams can now highlight repeat purchase rates, product penetration and the success of CRM campaigns. In the words of Dan and Mike, the addition of Exadata 11 months ago has been “a game changer.”  Amway has been able to dramatically reduce complexity, improve performance and increase business productivity and cost savings. For example, the number of indexes on the global data warehouse was reduced from more than 1,000 to less than 20.  Pulling data for the highest level distributors or the largest markets in the company now can be done in minutes instead of hours.  As a result, IT has shifted from performance tuning and keeping the system operational to higher-value business-focused activities. •       “The distributors that have been introduced to the BI reports have found them extremely helpful. Because they have never had this kind of information before, when they were presented with the reports, they wanted to take action immediately!”  -     Sales Development Manager in Latin America Without giving away more, the Amway case study presentation will be one of the unique customer sessions at OpenWorld this year. Speakers Dan Arganbright and Mike Olson have planned an interactive and entertaining session on Monday October 1 at 12:15pm in Moscone West, 2007. I’ll see you there!
