  • Oracle ACEs in the House

    - by Justin Kestelyn
    As is customary, the Oracle ACEs have invaded the Oracle Develop Conference agenda.Why? Because Oracle ACE-dom inherently is a stamp of not only expertise, but a unique ability to make that expertise useful to others. Plus, they're a group of "fine blokes" (UK. subjects, educate me: is that really a word?)Perhaps if you're not able to catch one of these sessions, you will be able to see the applicable ACE in action elsewhere, at a conference or user group meeting near you.

  • What is a “pretty and proper OO” way for handling sessions and authentication?

    - by asdfqwer
    Is coupling these two concepts a bad approach? As of right now I'm delegating all session handling and whether or not a user desires to logout in my config.inc file. As I was writing my Auth class I started wondering whether or not my Auth class should be taking care of most of the logic in my config.inc. Regardless, I'm sure there's a more elegant way of handling this... Here is what I have in my config.inc (also a large chunk of this code is based on a reply I found on SO except I can't find the source ._.): ini_set('session.name', 'SID'); # session management session_set_cookie_params(24*60*60); // set SID cookie lifetime session_start(); if(isset($_SESSION['LOGOUT']) { session_destroy(); // destroy session data $_SESSION = array(); // destroy session data sanity check setcookie('SID', '', time() - 24*60*60); // destroy session cookie data #header('Location: '.DOCROOT); } elseif(isset($_SESSION['SID_AUTH'])) { // verify user has authenticated if (!isset($_SESSION['SID_CREATED'])) { $_SESSION['SID_CREATED'] = time(); } elseif (time() - $_SESSION['SID_CREATED'] > 6*60*60) { // session started more than 6 hours ago session_regenerate_id(); // reset SID value $_SESSION['SID_CREATED'] = time(); // update creation time } if (isset($_SESSION['SID_MODIFIED']) && (time() - $_SESSION['SID_MODIFIED'] > 12*60*60)) { // last request was more than 12 hours ago session_destroy(); // destroy session data $_SESSION = array(); // destroy session data sanity check setcookie('SID', '', time() - 24*60*60); // destroy session cookie data } $_SESSION['SID_MODIFIED'] = time(); // update last activity time stamp }

  • How do I get a Canon MG, MP and MX series USB printer working?

    - by Old-linux-fan
    Printer MP6150 driver installed itself upon plugging in the printer. Printer is recognized (lsusb shows it) but does not mount. If the printer is recognized, the driver must be working (or?), but something is blocking the system from mounting the printer.

  • Microsoft IntelliMouse episodic pauses

    - by Rob Hills
    I have a Microsoft IntelliMouse connected via USB to a computer (directly, NOT via hub) currently running Ubuntu 11.10, but this problem also existed before we upgraded from 10.10. Every now and then (apparently randomly) the computer "pauses" for anything up to a few seconds. This usually occurs after a mouse movement and during the pause, the computer is completely unresponsive to mouse or keyboard. lsusb shows: Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 001 Device 002: ID 0409:0058 NEC Corp.

  • Why won't my graphics work in Ubuntu 12.04 LTS?

    - by user170974
    I'm very new to Ubuntu and to Linux in general, and took the leap and formatted my PC to Ubuntu 12.04 LTS very recently :) I seem to be having some trouble getting my graphics card to run properly, I looked over what information I could find but I still cannot get it up and running and figured this was a good place to ask for help. The information I can find on my graphics is as follows: (Terminal command) lspci outputs: 01:05.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] RS880M [Mobility Radeon HD 4225/4250] 02:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Madison [Mobility Radeon HD 5650/5750 / 6530M/6550M] I tried using a mixture of the following links: How do I fix my installation of ATI Catalyst Video Driver in 12.04 LTS? What is the correct way to install ATI Catalyst Video Drivers (fglrx)? Ubuntu Precise Installation Guide But it does not seem to work, since running fglrxinfo in terminal gives: display: :0.0 screen: 0 OpenGL vendor string: VMware, Inc. OpenGL renderer string: Gallium 0.4 on llvmpipe (LLVM 0x301) OpenGL version string: 1.4 (2.1 Mesa 9.0.3) What am I doing wrong here? All help appreciated ;) Edit: I have tried the legacy driver from www2.ati.com/drivers/linux/amd-driver-installer-catalyst-13-4-linux-x86.x86_64.zip I also tried the guide at https://launchpad.net/~makson96/+archive/fglrx which caused the system to crash (blackscreen, no boot) Neither seemed to work. I did however reinstall ubuntu 12.04 LTS, and re-tried both with no success. Reintalling ubuntu did however fix the broken dependencies problems, etc.

  • radeon display driver clones monitors while using Xinerama

    - by gregmuellegger
    I'm trying to get my two Radeon HD 4770 cards working with three monitors. Xinerama works so far in the way that I have two fully working monitors were I can move windows from one to the other.

  • ASP.NET site move to IIS7 results in gibberish characters in page output

    - by frankadelic
    I have an ASP.NET site that was working fine running on Windows Server 2003 / IIS6. I moved it to Windows Server 2008 / IIS7 and the aspx page output now includes gibberish text. For example: p???? ????? The majority of the page renders properly, but there is gibberish here and there. I have checked the event logs and there is nothing. Any idea what's going on here? How can I fix this? I have noticed that this issue shows up when I include multiple Server.Execute statements in the aspx code: <% Server.Execute("/inc/top.inc"); %> <% Server.Execute("/inc/footer.inc"); %> The .inc files above contain just html. It appears that the files have to be of a significant length to cause the error. Here is the sample html I've been testing with: <div class="logo"> <a href="/"> <img src="/logo.png" alt="logo" width="31" height="29" class="logoimg" /> </a> </div> <div class="logo"> <a href="/"> <img src="/logo.png" alt="logo" width="31" height="29" class="logoimg" /> </a> </div> <div class="logo"> <a href="/"> <img src="/logo.png" alt="logo" width="31" height="29" class="logoimg" /> </a> </div> <div class="logo"> <a href="/"> <img src="/logo.png" alt="logo" width="31" height="29" class="logoimg" /> </a> </div> <div class="logo"> <a href="/"> <img src="/logo.png" alt="logo" width="31" height="29" class="logoimg" /> </a> </div> <div class="logo"> <a href="/"> <img src="/logo.png" alt="logo" width="31" height="29" class="logoimg" /> </a> </div> Also, the gibberish characters appear inconsistently. If I ctrl+F5 the pages, the gibberish characters change and occasionally don't appear at all.

  • Storing a set of criteria in another table

    - by bendataclear
    I have a large table with sales data, useful data below: RowID Date Customer Salesperson Product_Type Manufacturer Quantity Value 1 01-06-2004 James Ian Taps Tap Ltd 200 £850 2 02-06-2004 Apple Fran Hats Hats Inc 30 £350 3 04-06-2004 James Lawrence Pencils ABC Ltd 2000 £980 ... Many rows later... ... 185352 03-09-2012 Apple Ian Washers Tap Ltd 600 £80 I need to calculate a large set of targets from table containing values different types, target table is under my control and so far is like: TargetID Year Month Salesperson Target_Type Quantity 1 2012 7 Ian 1 6000 2 2012 8 James 2 2000 3 2012 9 Ian 2 6500 At present I am working out target types using a view of the first table which has a lot of extra columns: SELECT YEAR(Date) , MONTH(Date) , Salesperson , Quantity , CASE WHEN Manufacturer IN ('Tap Ltd','Hats Inc') AND Product_Type = 'Hats' THEN True ELSE False END AS IsType1 , CASE WHEN Manufacturer = 'Hats Inc' AND Product_Type IN ('Hats','Coats') THEN True ELSE False END AS IsType2 ... ... , CASE WHEN Manufacturer IN ('Tap Ltd','Hats Inc') AND Product_Type = 'Hats' THEN True ELSE False END AS IsType24 , CASE WHEN Manufacturer IN ('Tap Ltd','Hats Inc') AND Product_Type = 'Hats' THEN True ELSE False END AS IsType25 FROM SalesTable WHERE [some stuff here] This is horrible to read/debug and I hate it!! I've tried a few different ways of simplifying this but have been unable to get it to work. The closest I have come is to have a third table holding the definition of the types with the values for each field and the type number, this can be joined to the tables to give me the full values but I can't work out a way to cope with multiple values for each field. Finally the question: Is there a standard way this can be done or an easier/neater method other than one column for each type of target? I know this is a complex problem so if anything is unclear please let me know. Edit - What I need to get: At the very end of the process I need to have targets displayed with actual sales: Type Year Month Salesperson TargetQty ActualQty 2 2012 8 James 2000 2809 2 2012 9 Ian 6500 6251 Each row of the sales table could potentially satisfy 8 of the types. Some more points: I have 5 different columns that need to be defined against the targets (or set to NULL to include any value) I have between 30 and 40 different types that need to be defined, several of the columns could contain as many as 10 different values For point 2, if I am using a row for each permutation of values, 2 columns with 10 values each would give me 100 rows for each sales person for each month which is a lot but if this is the only way to define multiple values I will have to do this. Sorry if this makes no sense!

What doesnt work is using custom JAR Here is my code: package com.micha; public class Hello1Bean { public Hello1Bean() {} String hi() {return "This is my hello message";} String hello(String name) {return "Hello" + name;} } And the php code <!DOCTYPE html> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title></title> </head> <body> <?php require_once ("java/Java.inc"); $world = new Java("com.micha.Hello1Bean"); echo java_values($world->hi()); echo "Hello Working Thingy\n\n"; ?> </body> </html> When I check http://localhost:8084/JavaBridge/mytest.php: javax.servlet.ServletException: java.lang.RuntimeException: PHP Fatal error: Uncaught [[o:Exception]:"java.lang.Exception: Invoke failed: [[o:Hello1Bean]]->hi.

  • Adding Parsekit To An Xcode Project

    - by Garry
    I am trying to add the Parsekit framework to my OSX Xcode project. I've never added a 3rd party framework before and I can't get it to work right. I dragged the included Xcode project into my 'Groups & Files' pane and chose to Add it to my project. I then dragged Parsekit.framework underneath the Link Binary With Libraries heading. Then I double-clicked my target app and added Parsekit as a Direct Dependency. I also added libicucore.dylib as a Linked Library (as it says to do this on their site). Finally, in the Build settings tab of my target info I set the Header Search Paths to /Users/path/to/include/directory and the Other Linker Flags to -ObjC -all_load. Running this as a debug build work fine with no errors. However, when I build my app to release and then try to run the executable created, the app fails to load with the following error message: MyApp cannot be opened because of a problem. Check with the developer to make sure myApp works with this version of Mac OS X. Here is the dump from the crash reporter: Process: MyApp [11658] Path: /Users/Garry/Programming/Xcode/Mac/MyApp/build/Release/MyApp.app/Contents/MacOS/MyApp Identifier: com.yourcompany.MyApp Version: ???

  • creating an array of objects in c++

    - by tim22
    I'm trying to create an array of objects in c++. I'm creating a employee object, from my constructor in my company class here: employee obj(int tempIdNum, double tempBase, double tempSales, double tempRate); emp[tempcount]=obj; (this doesn't work?) Emp is the name of the array which is defined here, located in my company h file. Employee emp[4]; more code: Company::Company(string name, string fileName){ string str; int tempcount; int tempIdnum; double tempBase; double tempSales; double tempRate; double num; double arr[16]; this->name=name; //Commission temp; ifstream readFile; readFile.open("fileName"); int inc=0; while(tempcount<4){ for(int i=0+inc; i<4+inc; i++){ readFile>>num; arr[i-inc]=num; } tempIdnum=(int)(arr[0]); tempBase=arr[1]; tempSales=arr[2]; tempRate=arr[3]; Employee obj(int tempIdNum, double tempBase, double tempSales, double tempRate); emp[tempcount]=obj; inc+=4; tempcount++; } readFile.close(); } Here is some more from my h file #include <string> include "Commission.h" using namespace std; ifndef Company_H define Company_H class Company{ private: string name; //name of company Employee emp[4]; //array of payrool info about 4 commission employees int numEmp; //number of employees public: Company(); Company(string name, string fileName); ~Company(); string getName(); Commission getEmployee(int element); int getNumEmp(); }; endif enter code here Does not compile: 46 E:\exercise2\Company.cpp no match for 'operator=' in '((Company*)this)-Company::emp[tempcount] = obj'

  • Big O Complexity of a method

    - by timeNomad
    I have this method: public static int what(String str, char start, char end) { int count=0; for(int i=0;i<str.length(); i++) { if(str.charAt(i) == start) { for(int j=i+1;j<str.length(); j++) { if(str.charAt(j) == end) count++; } } } return count; } What I need to find is: 1) What is it doing? Answer: counting the total number of end occurrences after EACH (or is it? Not specified in the assignment, point 3 depends on this) start. 2) What is its complexity? Answer: the first loops iterates over the string completely, so it's at least O(n), the second loop executes only if start char is found and even then partially (index at which start was found + 1). Although, big O is all about worst case no? So in the worst case, start is the 1st char & the inner iteration iterates over the string n-1 times, the -1 is a constant so it's n. But, the inner loop won't be executed every outer iteration pass, statistically, but since big O is about worst case, is it correct to say the complexity of it is O(n^2)? Ignoring any constants and the fact that in 99.99% of times the inner loop won't execute every outer loop pass. 3) Rewrite it so that complexity is lower. What I'm not sure of is whether start occurs at most once or more, if once at most, then method can be rewritten using one loop (having a flag indicating whether start has been encountered and from there on incrementing count at each end occurrence), yielding a complexity of O(n). In case though, that start can appear multiple times, which most likely it is, because assignment is of a Java course and I don't think they would make such ambiguity. Solving, in this case, is not possible using one loop... WAIT! Yes it is..! Just have a variable, say, inc to be incremented each time start is encountered & used to increment count each time end is encountered after the 1st start was found: inc = 0, count = 0 if (current char == start) inc++ if (inc > 0 && current char == end) count += inc This would also yield a complexity of O(n)? Because there is only 1 loop. Yes I realize I wrote a lot hehe, but what I also realized is that I understand a lot better by forming my thoughts into words...

  • Gamification: Oracle Well and Truly Engaged

    - by ultan o'broin
    Here is a quick roundup of Oracle gamification events and activities. But first, some admissions to a mis-spent youth from Oracle vice presidents Jeremy Ashley, Nigel King, Mike Rulf, Dave Stephens, and Clive Swan, (the video was used as an introduction to the Oracle Applications User Experience Gamification Design Jam): Other videos from that day are available, including the event teaser A History of Games, and about UX and Gamification are here, and here. On to the specifics: Marta Rauch's (@martarauch) presentations Tapping Enterprise Communities Through Gamification at STC 2012 and Gamification is Here: Build a Winning Plan at LavaCon 2012. Erika Webb's (@erikanollwebb) presentation Enterprise User Experience: Making Work Engaging at Oracle at the G-Summit 2012. Kevin Roebuck's blog outlining his team's gamification engagements, including the G-Summit, Innovations in Online Learning, and the America's Cup for Java Kids Virtual Design Competition at the Immersive Education Summit. Kevin also attended the UX Design Jam. Jake Kuramoto (@jkuramot) of Oracle AppsLab's (@theappslab) thoughts on the Gamification Design Jam. Jake and Co have championed gamification in the apps space for a while now. If you know of more Oracle gamification events or articles of interest, then find the comments.

The skinny. The Challenge is a modified hackathon, designed to run during OpenWorld and JavaOne (@javaoneconf), and attendees of both conferences are welcome to join and compete for the single prize of $500 in Amazon gift cards. There’s only one prize, so bring your A-game. The Challenge begins Sunday, September 30 at 7 PM and ends Wednesday, October 3 at 4 PM. You can and should register now, but we won’t begin approving  registrations until Sunday at 7 PM. For legal reasons, you’ll need to register with a corporate email address, not a free webmail one, e.g. Gmail, Hotmail, Outlook, Yahoo Mail, ISP-provided mail, etc. If you work for a competitor of Oracle, sorry but you’re not eligible. Everything you need is in the cloud, including support, but if you need help or have questions, visit office hours in the OTN Lounge in the Howard Street tent Monday, October 1 and Tuesday, October 2 4-8 PM to get help from the product team. The judging begins Wednesday, October 3 at 4 PM. To be considered for the prize, you’ll need to attend to demo your working code to the judges. Attendees with badges from either OpenWorld or JavaOne are welcome in the OTN Lounge, so you’ll need one of those too. Did I mention, register now? Be sure to check out Jake's original post for the long-winded explanations.

  • Creating nodes porgramatically in Drupal 6

    - by John
    Hey, I have been searching for how to create nodes in Drupal 6. I found some entries here on stackoverflow, but the questions seemed to either be for older versions or the solutions did not work for me. Ok, so here is my current process for trying to create $node = new stdClass(); $node->title = "test title"; $node->body = "test body"; $node->type= "story"; $node->created = time(); $node->changed = $node->created; $node->status = 1; $node->promote = 1; $node->sticky = 0; $node->format = 1; $node->uid = 1; node_save( $node ); When I execute this code, the node is created, but when I got the administration page, it throws the following errors: warning: Invalid argument supplied for foreach() in C:\wamp\www\steelylib\includes\menu.inc on line 258. warning: Invalid argument supplied for foreach() in C:\wamp\www\steelylib\includes\menu.inc on line 258. user warning: Duplicate entry '36' for key 1 query: INSERT INTO node_comment_statistics (nid, last_comment_timestamp, last_comment_name, last_comment_uid, comment_count) VALUES (36, 1269980590, NULL, 1, 0) in C:\wamp\www\steelylib\sites\all\modules\nodecomment\nodecomment.module on line 409. warning: Invalid argument supplied for foreach() in C:\wamp\www\steelylib\includes\menu.inc on line 258. warning: Invalid argument supplied for foreach() in C:\wamp\www\steelylib\includes\menu.inc on line 258. I've looked at different tutorials, and all seem to follow the same process. I'm not sure what I am doing wrong. I am using Drupal 6.15. When I roll back the database (to right before I made the changes) the errors are gone. Any help is appreciated!

  • Visual C++ Assembly link library troubles

    - by Sanarothe
    Hi. I'm having a problem having my projects built in VC++ Express 2008... I'm using a library, irvine32.inc/lib. INCLUDE Irvine32.inc works for me at school (On already configured VS environments) by default, but at home (Windows 7 x64) I'm having a boatload of issues. My original post here was that a file that irvine32.inc referenced, in the same folder, 'could not be opened.' Added irvine folder to the include path for specific project, progress. Then I was getting an error with mt.exe, but a suggestion on the MSDN suggested turn off antivirus, and now project does build but when I run a program that does NOT reference anything in irvine32, it tells me repeatedly that my project has triggered a breakpoint, and allows me to continue or break. Continue just pops the same window, break loads another popup telling me that "No symbols are loaded for any call stack frame. Source code cannot be displayed." This popup lets me view the disassembly. I tested it with and without working statements, it just throws the same breakpoint on the first line of code. Now, if I run the program when it DOES require something from the include file, in this case, DumpRegs: INCLUDE Irvine32.inc .data .code main PROC mov ebx,1000h mov eax,1000h add eax,ebx call DumpRegs main ENDP END main This gives me 1main.obj : error LNK2019: unresolved external symbol _DumpRegs@0 referenced in function _main@0 1C:\Users\Cameron\csis165\Lab8_CCarroll\Debug\Lab8_CCarroll.exe : fatal error LNK1120: 1 unresolved externals This does NOT happen when I build a project from the book author's examples, which has the same include statement. I'm baffled. :(

  • function taking in an input image and different kernel size

    - by drifterOcean19
    I have this filtering function that takes an input image, performs convolution using a given kernel, and returns the resulting image. However, I can't seem to work it out how to make it takes different kernel sizes.For example instead of pre-defined 3x3 kernel as below in the code, it could instead take 5x5 or 7x7. and then the user could input the type of kernel/filter they want(Depending on the intended effect). I can't seem to put my head around it. i'm quite new to matlab. function [newImg] = kernelFunc(imgB) img=imread(imgB); figure,imshow(img); img2=zeros(size(img)+2); newImg=zeros(size(img)); for rgb=1:3 for x=1:size(img,1) for y=1:size(img,2) img2(x+1,y+1,rgb)=img(x,y,rgb); end end end for rgb=1:3 for i= 1:size(img2,1)-2 for j=1:size(img2,2)-2 window=zeros(9,1); inc=1; for x=1:3 for y=1:3 window(inc)=img2(i+x-1,j+y-1,rgb); inc=inc+1; end end kernel=[1;2;1;2;4;2;1;2;1]/16; med=window.*kernel; disp(med); med=sum(med); med=floor(med); newImg(i,j,rgb)=med; end end end newImg=uint8(newImg); figure,imshow(newImg); end

  • Rails database relationships

    - by Danny McClelland
    Hi Everyone, I have three models that I want to interact with each other. Kase, Person and and Company. I have (I think) setup the relationships correctly: class Kase < ActiveRecord::Base #HAS ONE COMPANY has_one :company #HAS MANY PERSONS has_many :persons class Person < ActiveRecord::Base belongs_to :company class Company < ActiveRecord::Base has_many :persons def to_s; companyname; end I have put the select field on the create new Kase view, and the create new Person view as follows: <li>Company<span><%= f.select :company_id, Company.all %> </span></li> All of the above successfully shows a drop down menu dynamically populated with the company names within Companies. What I am trying to do is display the contact of the Company record within the kase and person show.html.erb. For example, If I have a company called "Acme, Inc." and create a new Kase called "Random Case" and choose within the create new case page "Acme, Inc." from the companies drop down menu. I would then want to display "Acme, Inc" along with "Acme, Inc. Mobile" etc. on the "Random Case" show.html.erb. I hope this makes sense to somebody! Thanks, Danny
