Excluding the impact of Sun Microsystems, Inc., which Oracle acquired on January 26, 2010, GAAP total revenue grew 7%. GAAP new software license revenues were up 13% to $1.7 billion, and up 10% to $1.7 billion excluding Sun. GAAP software license updates and product support revenues were up 13% to $3.3 billion, while non-GAAP software license updates and product support revenues were up 12% to $3.3 billion. GAAP operating income was down 5% to $1.8 billion, and GAAP operating margin was 29%. Non-GAAP operating income was up 13% to $2.9 billion, and non-GAAP operating margin was 45%. GAAP net income was down 10% to $1.2 billion, while non-GAAP net income was up 9% to $1.9 billion. GAAP earnings per share were $0.23, down 11% compared to last year while non-GAAP earnings per share were up 9% to $0.38. GAAP operating cash flow on a trailing twelve-month basis was $8.2 billion. "Our solid top line growth, coupled with disciplined expense management, was key in generating $8.0 billion of free cash flow over the last twelve months," said Oracle CFO Jeff Epstein."The Sun integration is going even better than we expected," said Oracle President, Safra Catz. "We believe that Sun will make a significant contribution to our fourth quarter earnings per share as well as meet the profitability goals we set for next year.""Exadata is the fastest growing product in Oracle's history," said Oracle President, Charles Phillips. "Introduced a little over a year ago, the Exadata pipeline is now approaching $400 million with Q4 bookings forecast at nearly $100 million. This strengthens both sales growth and profitability in our Sun server and storage businesses.""Every quarter we grab huge chunks of market share from SAP," said Oracle CEO, Larry Ellison. "SAP's most recent quarter was the best quarter of their year, only down 15%, while Oracle's application sales were up 21%. But SAP is well ahead of us in the number of CEOs for this year, announcing their third and fourth, while we only had one."In addition, Oracle's Board of Directors declared a cash dividend of $0.05 per share of outstanding common stock to be paid to stockholders of record as of the close of business on April 14, 2010, with a payment date of May 5, 2010.

  • Given a large set of vertices in a non-convex polygon, how can i find the edges?

    - by tommy chheng
    I have a set of vertices(called A) and I want to find all the border vertices such that this border vertices set is an outline of the shape. Many of the vertices in A are redundant because they are inside the shape, I want to get rid of these vertices. My question is similar to http://stackoverflow.com/questions/477867/best-algorithm-to-find-the-edges-polygon-of-vertices but i need it to work for a non-convex polygon case.

  • Program Managers: Do you exist? How do I become you?

    - by sixtyfootersdude
    I am a Computer Science major who is interesting in exploring a career as a program manager. I knew since starting my degree that that was the role that was interested in but I just found out the actual job name recently. Q: Is this a common position? Do many companies have "program managers"? What should I do/read to improve my chances to become a project manager upon graduation? I have already completed three co-op terms at different companies none of which had this position.

  • PHP: Can pcntl_alarm() and socket_select() peacefully exist in the same thread?

    - by DWilliams
    I have a PHP CLI script mostly written that functions as a chat server for chat clients to connect to (don't ask me why I'm doing it in PHP, thats another story haha). My script utilizes the socket_select() function to hang execution until something happens on a socket, at which point it wakes up, processes the event, and waits until the next event. Now, there are some routine tasks that I need performed every 30 seconds or so (check of tempbanned users should be unbanned, save user databases, other assorted things). From what I can tell, PHP doesn't have very great multi-threading support at all. My first thought was to compare a timestamp every time the socket generates an event and gets the program flowing again, but this is very inconsistent since the server could very well sit idle for hours and not have any of my cleanup routines executed. I came across the PHP pcntl extensions, and it lets me use assign a time interval for SIGALRM to get sent and a function get executed every time it's sent. This seems like the ideal solution to my problem, however pcntl_alarm() and socket_select() clash with each other pretty bad. Every time SIGALRM is triggered, all sorts of crazy things happen to my socket control code. My program is fairly lengthy so I can't post it all here, but it shouldn't matter since I don't believe I'm doing anything wrong code-wise. My question is: Is there any way for a SIGALRM to be handled in the same thread as a waiting socket_select()? If so, how? If not, what are my alternatives here? Here's some output from my program. My alarm function simply outputs "Tick!" whenever it's called to make it easy to tell when stuff is happening. This is the output (including errors) after allowing it to tick 4 times (there were no actual attempts at connecting to the server despite what it says): [05-28-10 @ 20:01:05] Chat server started on 192.168.1.28 port 4050 [05-28-10 @ 20:01:05] Loaded 2 users from file PHP Notice: Undefined offset: 0 in /home/danny/projects/PHPChatServ/ChatServ.php on line 112 PHP Warning: socket_select(): unable to select [4]: Interrupted system call in /home/danny/projects/PHPChatServ/ChatServ.php on line 116 [05-28-10 @ 20:01:15] Tick!

  • How to change the primary key to be non-clustered?

    - by AngryHacker
    Part-time reluctant DBA here. I want to change an existing primary key index from clustered to non-clustered. And the syntax is escaping me. This is how it's scripted out right now. ALTER TABLE [dbo].[Config] WITH NOCHECK ADD CONSTRAINT [PK_Config] PRIMARY KEY CLUSTERED ( [ConfigID] ) ON [PRIMARY] I am not seeing an ALTER CONSTRAINT statement in the online docs.

  • How can I execute a non-blocking System.Beep()?

    - by Siracuse
    In C# I can perform a Console.Beep(). However, if you specify a duration of say 1000, or 1 second, it will not execute the next line of code until that second passes. Is there any way possible to execute Console.Beep() in a non-blocking fashion so it will continue to beep and still continue executing the code below it while beeping?

  • "The specified table does not exist" - for the administrator it does! Vista only issue

    - by Simon Nunn
    Hello, I've got a weird bug occurring in a compact database on a Vista deployment machine. Basically the sdf file seem to be schizophrenic. The client application get the entitled error when running as a user but not when I use run as administrator. I don't see this problem on my XP development machine. I installed management studio onto the deployment machine and opened two versions of the application, one as user and one as administrator. When I query: SELECT TABLE_NAME FROM INFORMATION_SCHEMA.TABLES I see 21 tables on the one and 26 on the other, and the administrator is seeing less tables. It turns out that the user version, with 26 rows, is a previous incarnation of this database. Any ideas on why this is happening?

  • How can I use non-Silverlight assemblies in a Silverlight app?

    - by norbertB
    I'm working an project (pure hobby, "Sharping my skills") which has one unified back-end and multiple front-ends (ASP.NET MVC 1.0/JQuery and Silverlight 2). When I try to add reference to my business layer assembly in the Silverlight 2 project (VS2008); It gets rejected, because it's not a Silverlight assembly. Is their a way to include and reference a non-Silverlight assembly in a Silverlight app?

  • Writing a Servlet that checks to see if JSP's exist and forwards to another JSP if they aren't

    - by Omar Kooheji
    I've beeb tasked with writing a servlet that intercepts a call to and JSP in a specific directoy, check that the file exists and if it does just forwarding to that file, if if doesn't I'm to forward to a default JSP. I've setup the web.xml as follows: <servlet> <description>This is the description of my J2EE component</description> <display-name>This is the display name of my J2EE component</display-name> <servlet-name>CustomJSPListener</servlet-name> <servlet-class> ... CustomJSPListener</servlet-class> <load-on-startup>1</load-on-startup> </servlet> ... <servlet-mapping> <servlet-name>CustomJSPListener</servlet-name> <url-pattern>/custom/*</url-pattern> </servlet-mapping> And the doGet method of the servlet is as follows: public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { logger.debug(String.format("Intercepted a request for an item in the custom directory [%s]",request.getRequestURL().toString())); String requestUri = request.getRequestURI(); // Check that the file name contains a text string if (requestUri.toLowerCase(Locale.UK).contains("someText")){ logger.debug(String.format("We are interested in this file [%s]",requestUri)); File file = new File(requestUri); boolean fileExists = file.exists(); logger.debug(String.format("Checking to see if file [%s] exists [%s].",requestUri,fileExists)); // if the file exists just forward it to the file if (fileExists){ getServletConfig().getServletContext().getRequestDispatcher( requestUri).forward(request,response); } else { // Otherwise redirect to default.jsp getServletConfig().getServletContext().getRequestDispatcher( "/custom/default.jsp").forward(request,response); } } else { // We aren't responsible for checking this file exists just pass it on to the requeseted jsp getServletConfig().getServletContext().getRequestDispatcher( requestUri).forward(request,response); } } This seems to result in an error 500 from tomcat, I think this is because the servlet is redirecting to the same folder which is then being intercepted again by the servlet, resulting in an infinite loop. Is there a better way to do this? I'm lead to believe that I could use filters to do this, but I don't know very much about them.

  • What web based programming environments exist, on which to learn?

    - by jjclarkson
    I loved appjet (the programming environment) before it was taken over by Google. What other web based complete programming environments are out there? Which one do you think is best for starting to do real world coding the fastest? I really think coding from your browser will make programming more accessible to the public. Are there any out there that use a vim style, (e.g. jsvi) in combination with free server side hosting? The last time I looked at Bespin it was a little green. Are there others?

  • Does an IFilter Exist for Indexing Source Code Files?

    - by AMissico
    Anybody know of an IFilter that can index source code files beyond what the "Plain Text" filter can provide, with possibly a custom "Property Set" specific to programming? For example, I have 835MB in 41,000 files and 8,200 folders in my "Code Library" folder. I would like to perform searches such as "select distinct attributes on properties" or "select class exceptions" or "select classes with nested private classes". Preferrably, the IFilter can distinguish between various languages, so I can perform a query like "select class exceptions in VB.NET" or "select 'resume next' in VBScript". Other Examples "select all enum from folder('microsoft source code') in namespace 'system.io'"

  • Should BASIC continue to be recommended for non-programmers and beginners?

    - by Casey
    I just came across a new BASIC implementation for Google Android application called Simple. You can read about it here: http://google-opensource.blogspot.com/2009/07/programming-made-simple.html Clearly, a lot of time and effort has been recently put into enabling this functionality for Android. Should the software industry continue to encourage non-programmers into learning BASIC, or are modern languages like C#, Python, Ruby more appropriate at this time?

  • Unable to create index because of duplicate that doesn't exist?

    - by Alex Angas
    I'm getting an error running the following Transact-SQL command: CREATE UNIQUE NONCLUSTERED INDEX IX_TopicShortName ON DimMeasureTopic(TopicShortName) The error is: Msg 1505, Level 16, State 1, Line 1 The CREATE UNIQUE INDEX statement terminated because a duplicate key was found for the object name 'dbo.DimMeasureTopic' and the index name 'IX_TopicShortName'. The duplicate key value is (). When I run SELECT * FROM sys.indexes WHERE name = 'IX_TopicShortName' or SELECT * FROM sys.indexes WHERE object_id = OBJECT_ID(N'[dbo].[DimMeasureTopic]') the IX_TopicShortName index does not display. So there doesn't appear to be a duplicate. I have the same schema in another database and can create the index without issues there. Any ideas why it won't create here?
