• What causes player box/world geometry glitches in old games?

  - by Alexander

  I'm looking to understand and find the terminology for what causes - or allows - players to interfere with geometry in old games. Famously, ID's Quake3 gave birth to a whole community of people breaking the physics by jumping, sliding, getting stuck and launching themselves off points in geometry. Some months ago (though I'd be darned if I can find it again!) I saw a conference held by Bungie's Vic DeLeon and a colleague in which Vic briefly discussed the issues he ran into while attempting to wrap 'collision' objects (please correct my terminology) around environment objects so that players could appear as though they were walking on organic surfaces, while not clipping through them or appear to be walking on air at certain points, due to complexities in the modeling. My aim is to compose a case study essay for University in which I can tackle this issue in games, drawing on early exploits and how techniques have changed to address such exploits and to aid in the gameplay itself. I have 3 current day example of where exploits still exist, however specifically targeting ID Software clearly shows they've massively improved their techniques between Q3 and Q4. So in summary, with your help please, I'd like to gain a slightly better understanding of this issue as a whole (its terminology mainly) so I can use terms and ask the right questions within the right contexts. In practical application, I know what it is, I know how to do it, but I don't have the benefit of level design knowledge yet and its technical widgety knick-knack terms =) Many thanks in advance AJ

• "Expected initializer before '<' token" in header file

  - by Sarah

  I'm pretty new to programming and am generally confused by header files and includes. I would like help with an immediate compile problem and would appreciate general suggestions about cleaner, safer, slicker ways to write my code. I'm currently repackaging a lot of code that used to be in main() into a Simulation class. I'm getting a compile error with the header file for this class. I'm compiling with gcc version 4.2.1. // Simulation.h #ifndef SIMULATION_H #define SIMULATION_H #include <cstdlib> #include <iostream> #include <cmath> #include <string> #include <fstream> #include <set> #include <boost/multi_index_container.hpp> #include <boost/multi_index/hashed_index.hpp> #include <boost/multi_index/member.hpp> #include <boost/multi_index/ordered_index.hpp> #include <boost/multi_index/mem_fun.hpp> #include <boost/multi_index/composite_key.hpp> #include <boost/shared_ptr.hpp> #include <boost/tuple/tuple_comparison.hpp> #include <boost/tuple/tuple_io.hpp> #include "Parameters.h" #include "Host.h" #include "rng.h" #include "Event.h" #include "Rdraws.h" typedef multi_index_container< // line 33 - first error boost::shared_ptr< Host >, indexed_by< hashed_unique< const_mem_fun<Host,int,&Host::getID> >, // 0 - ID index ordered_non_unique< tag<age>,const_mem_fun<Host,int,&Host::getAgeInY> >, // 1 - Age index hashed_non_unique< tag<household>,const_mem_fun<Host,int,&Host::getHousehold> >, // 2 - Household index ordered_non_unique< // 3 - Eligible by age & household tag<aeh>, composite_key< Host, const_mem_fun<Host,int,&Host::getAgeInY>, const_mem_fun<Host,bool,&Host::isEligible>, const_mem_fun<Host,int,&Host::getHousehold> > >, ordered_non_unique< // 4 - Eligible by household (all single adults) tag<eh>, composite_key< Host, const_mem_fun<Host,bool,&Host::isEligible>, const_mem_fun<Host,int,&Host::getHousehold> > >, ordered_non_unique< // 5 - Household & age tag<ah>, composite_key< Host, const_mem_fun<Host,int,&Host::getHousehold>, const_mem_fun<Host,int,&Host::getAgeInY> > > > // end indexed_by > HostContainer; typedef std::set<int> HHSet; class Simulation { public: Simulation( int sid ); ~Simulation(); // MEMBER FUNCTION PROTOTYPES void runDemSim( void ); void runEpidSim( void ); void ageHost( int id ); int calcPartnerAge( int a ); void executeEvent( Event & te ); void killHost( int id ); void pairHost( int id ); void partner2Hosts( int id1, int id2 ); void fledgeHost( int id ); void birthHost( int id ); void calcSI( void ); double beta_ij_h( int ai, int aj, int s ); double beta_ij_nh( int ai, int aj, int s ); private: // SIMULATION OBJECTS double t; double outputStrobe; int idCtr; int hholdCtr; int simID; RNG rgen; HostContainer allHosts; // shared_ptr to Hosts - line 102 - second error HHSet allHouseholds; int numInfecteds[ INIT_NUM_AGE_CATS ][ INIT_NUM_STYPES ]; EventPQ currentEvents; // STREAM MANAGEMENT void writeOutput(); void initOutput(); void closeOutput(); std::ofstream ageDistStream; std::ofstream ageDistTStream; std::ofstream hhDistStream; std::ofstream hhDistTStream; std::string ageDistFile; std::string ageDistTFile; std::string hhDistFile; std::string hhDistTFile; }; #endif I'm hoping the other files aren't so relevant to this problem. When I compile with g++ -g -o -c a.out -I /Applications/boost_1_42_0/ Host.cpp Simulation.cpp rng.cpp main.cpp Rdraws.cpp I get Simulation.h:33: error: expected initializer before '<' token Simulation.h:102: error: 'HostContainer' does not name a type and then a bunch of other errors related to not recognizing the HostContainer. It seems like I have all the right Boost #includes for the HostContainer to be understood. What else could be going wrong? I would appreciate immediate suggestions, troubleshooting tips, and other advice about my code. My plan is to create a "HostContainer.h" file that includes the typedef and structs that define its tags, similar to what I'm doing in "Event.h" for the EventPQ container. I'm assuming this is legal and good form.

• Good websites and/or books to learn game algorithms?

  - by Moshe

  I'm interested in learning video game algorithms. (For iPhone particularly, but generally as well. I assume certain concepts are the same.) I am best off (personally) learning from a book but websites are useful too. What has helped you learn game programming algorithms and concepts? EDIT: As per request, I'll clarify the types of algorithms... I was looking for any algorithms really, but I guess I was interested in (top-down view) platformer algorithms, but, now that you mention it, Seth, I do wonder about chess...

• How to access private static target field in aspect in AspectJ?

  I have a simple class Main with private static int x and an aspect that should output the old value of x before it is reassigned: public class Main { private static int x; public static void main(String[] args) { foo(7); } public static void foo(int y) { x = y; } } and MonitorX.aj: public aspect MonitorX { before() : set(static int Main.x){ System.out.println(Main.x); } } which doesn't work since I can't access private x using Main.x. I've also tried: before(int t) : set(static int Main.x) && target(t){ System.out.println(t); } which doesn't work either (nothing is outputted, if I try to output string, it seems that the aspect isn't invoked at all). However printing out the new value that is being assigned works: before(int newVal) : set(static int Main.x) && args(newVal){ System.out.println(newVal); } What am I missing?

• List of fundamental data structures - what am I missing?

  - by jboxer

  I've been studying my fundamental data structures a bunch recently, trying to make sure I've got them down cold. By "fundamental", I mean the real basic ones. Fancy ones like Red-Black Trees and Bloom Filters are clearly worth knowing, but they're usually either enhancements of fundamental ones (Red-Black Trees are binary search trees with special properties to keep them balanced) or they're only useful in very specific situations (Bloom Filters). So far, I'm "fluent" in the following data structures: Arrays Linked Lists Stacks/Queues Binary Search Trees Heaps/Priority Queues Hash Tables However, I feel like I'm missing something. Are there any fundamental ones that I'm forgetting about? EDIT: Added these after posting the question Strings (suggested by catchmeifyoutry) Sets (suggested by Peter) Graphs (suggested by Nick D and aJ) B-Trees (Suggested by tloach) I'm a little on-the-fence about whether these are too fancy or not, but I think they're different enough from the fundamental structures (and important enough) to be worth studying as fundamental.

• Go Big or Go Special

  - by Ajarn Mark Caldwell

  Watching Shark Tank tonight and the first presentation was by Mango Mango Preserves and it highlighted an interesting contrast in business trends today and how to capitalize on opportunities.  <Spoiler Alert> Even though every one of the sharks was raving about the product samples they tried, with two of them going for second and third servings, none of them made a deal to invest in the company.</Spoiler>  In fact, one of the sharks, Kevin O’Leary, kept ripping into the owners with statements to the effect that he thinks they are headed over a financial cliff because he felt their costs were way out of line and would be their downfall if they didn’t take action to radically cut costs. He said that he had previously owned a jams and jellies business and knew the cost ratios that you had to have to make it work.  I don’t doubt he knows exactly what he’s talking about and is 100% accurate…for doing business his way, which I’ll call “Go Big”.  But there’s a whole other way to do business today that would be ideal for these ladies to pursue. As I understand it, based on his level of success in various businesses and the fact that he is even in a position to be investing in other companies, Kevin’s approach is to go mass market (Go Big) and make hundreds of millions of dollars in sales (or something along that scale) while squeezing out every ounce of cost that you can to produce an acceptable margin.  But there is a very different way of making a very successful business these days, which is all about building a passionate and loyal community of customers that are rooting for your success and even actively trying to help you succeed by promoting your product or company (Go Special).  This capitalizes on the power of social media, niche marketing, and The Long Tail.  One of the most prolific writers about capitalizing on this trend is Seth Godin, and I hope that the founders of Mango Mango pick up a couple of his books (probably Purple Cow and Tribes would be good starts) or at least read his blog.  I think the adoration expressed by all of the sharks for the product is the biggest hint that they have a remarkable product and that they are perfect for this type of business approach. Both are completely valid business models, and it may certainly be that the scale at which Kevin O’Leary wants to conduct business where he invests his money is well beyond the long tail, but that doesn’t mean that there is not still a lot of money to be made there.  I wish them the best of luck with their endeavors!

• Purple Cows, Copernicus, and Shampoo – Lessons in Customer Experience

  - by Christina McKeon

  What makes a great customer experience? And, why should you or your organization care? These are the questions that set the stage for the Oracle Customer Experience Summit, which kicked off yesterday in San Francisco. Day 1: The first day was filled with demos and insights from customer experience experts and Oracle customers sharing what it takes to deliver great customer experiences. Author Seth Godin delivered an entertaining presentation that included an in-depth exploration of the always-connected, always-sharing experience revolution that we are witnessing and yes, talked about the purple cow. It turns out that customer experience is your way to be the purple cow. Before everyone headed out to see Pearl Jam and Kings of Leon at the Oracle customer appreciation event, the day wrapped up with a discussion around building a customer-centric culture. Where do you start? Whom does it involve? What are some pitfalls to avoid? Day 2: The second day addressed the details behind all the questions brought up at the end of Day 1. Before you start on a customer experience initiative, Paul Hagen noted that you must understand you will forge a path similar to Copernicus. You will be proposing ideas and approaches that challenge current thinking in your organization. Just as Copernicus' heliocentric theory started a scientific revolution, your customer-centric efforts will start an experience revolution. If you think customer experience is like a traditional marketing approach, think again. It’s not about controlling your customers and leading them where you want them to go. It might sound like heresy to some, but your customers are already in control, whether or not your company realizes and acknowledges it. And, to survive and thrive, you'll have to focus on customers by thinking outside-in and working towards a brand that is better and more authentic. We learned how Vail Resorts takes this customer-centric approach. Employees must experience the mountain themselves and understand the experience from the guest’s standpoint. This has created a culture where employees do things for guests that are not expected. We also learned a valuable lesson in designing and innovating customer-centered experiences from Kerry Bodine. First you make the thing, and then you make the thing right. In this case, the thing is customer experience. Getting customer experience right means iterative prototyping and testing of your ideas. This is where shampoo comes in—think lather, rinse, repeat. Be prepared to keep repeating until the customer experience is right. Many of these sessions will be posted to YouTube in the coming weeks so be sure to subscribe to our CX channel.

• This Week in Geek History: Gmail Goes Public, Deep Blue Wins at Chess, and the Birth of Thomas Edison

  - by Jason Fitzpatrick

  Every week we bring you a snapshot of the week in Geek History. This week we’re taking a peek at the public release of Gmail, the first time a computer won against a chess champion, and the birth of prolific inventor Thomas Edison. Gmail Goes Public It’s hard to believe that Gmail has only been around for seven years and that for the first three years of its life it was invite only. In 2007 Gmail dropped the invite only requirement (although they would hold onto the “beta” tag for another two years) and opened its doors for anyone to grab a username @gmail. For what seemed like an entire epoch in internet history Gmail had the slickest web-based email around with constant innovations and features rolling out from Gmail Labs. Only in the last year or so have major overhauls at competitors like Hotmail and Yahoo! Mail brought other services up to speed. Can’t stand reading a Week in Geek History entry without a random fact? Here you go: gmail.com was originally owned by the Garfield franchise and ran a service that delivered Garfield comics to your email inbox. No, we’re not kidding. Deep Blue Proves Itself a Chess Master Deep Blue was a super computer constructed by IBM with the sole purpose of winning chess matches. In 2011 with the all seeing eye of Google and the amazing computational abilities of engines like Wolfram Alpha we simply take powerful computers immersed in our daily lives for granted. The 1996 match against reigning world chest champion Garry Kasparov where in Deep Blue held its own, but ultimately lost, in a  4-2 match shook a lot of people up. What did it mean if something that was considered such an elegant and quintessentially human endeavor such as chess was so easy for a machine? A series of upgrades helped Deep Blue outright win a match against Kasparov in 1997 (seen in the photo above). After the win Deep Blue was retired and disassembled. Parts of Deep Blue are housed in the National Museum of History and the Computer History Museum. Birth of Thomas Edison Thomas Alva Edison was one of the most prolific inventors in history and holds an astounding 1,093 US Patents. He is responsible for outright inventing or greatly refining major innovations in the history of world culture including the phonograph, the movie camera, the carbon microphone used in nearly every telephone well into the 1980s, batteries for electric cars (a notion we’d take over a century to take seriously), voting machines, and of course his enormous contribution to electric distribution systems. Despite the role of scientist and inventor being largely unglamorous, Thomas Edison and his tumultuous relationship with fellow inventor Nikola Tesla have been fodder for everything from books, to comics, to movies, and video games. Other Notable Moments from This Week in Geek History Although we only shine the spotlight on three interesting facts a week in our Geek History column, that doesn’t mean we don’t have space to highlight a few more in passing. This week in Geek History: 1971 – Apollo 14 returns to Earth after third Lunar mission. 1974 – Birth of Robot Chicken creator Seth Green. 1986 – Death of Dune creator Frank Herbert. Goodnight Dune. 1997 – Simpsons becomes longest running animated show on television. Have an interesting bit of geek trivia to share?

• SQL – Quick Start with Admin Sections of NuoDB – Manage NuoDB Database

  - by Pinal Dave

  In the yesterday’s blog post we have seen that it is extremely easy to install the NuoDB database on your local machine. Now that the application is properly set up, let us explore NuoDB a bit more and get you familiar with the how it works and what the important areas of the NuoDB are that you should learn. As we have already installed NuoDB, now we will quickly start with two of the important areas in NuoDB: 1) Admin and 2) Explorer. In this blog post I will explore how the Admin Section of the NuoDB Console works.  In the next blog post we will learn how the Explorer Section works. Let us go to the NuoDB Console by typing the following URL in your browser: http://localhost:8080/ It will bring you to the following screen: On this screen you can see a big Start QuickStart button. Click on the button and it will bring you to following screen. On this screen you will find very important information about Domain and Database Settings. It is our habit that we do not read what is written on the screen and keep on clicking on continue without reading. While we are familiar with most wizards, we can often miss the very important message on the screen. Please note the information of Domain Settings and Database Settings from the following screen before clicking on Create Database. Domain Settings User: quickstart Password: quickstart Database Settings User: dba Password: goalie Database: test Schema: HOCKEY Once you click on the Create Database button it will immediately start creating sample database. First, it will start a Storage Manager and right after that it will start a Transaction Engine. Once the engine is up, it will Create a Schema and Sample Data. On the success of the creating the sample database it will show the following screen. Now is the time where we can explore the NuoDB Admin or NuoDB Explorer. If you click on Admin, it will first show following login screen. Enter for the username “domain” and for the password “bird”. Alternatively you can enter “quickstart”  twice for username and password.  It works as too. Once you enter into the Admin Section, on the left side you can see information about NuoDB and Admin Console and on the right side you can see the domain overview area. From this Administrative section you can do any of the following tasks: Create a view of the entire domain Add and remove databases Start and stop NuoDB Transaction Engines and Storage Managers Monitor transaction across all the NuoDB databases On the right side of the Admin Section we can see various information about a particular NuoDB domain. You can quickly view various alerts, find out information about the number of host machines that are provisioned for the domain, and see the number of databases and processes that are running in the domain. If you click on the “1 host” link you will be able to see various processes, CPU usage and other information. In the Processes Section you can see that there are two different types of processes. The first process (where you can see the floppy drive icon) represents a running Storage Manager process and the second process a running Transaction Engine process. You can click on the links for the Storage Manager and Transaction Engine to see further statistical details right down to the last byte of the data. There are various charts available for analysis as well. I think the product is quite mature and the user can add different monitor charts to the Admin section. Additionally, the Admin section is the place where you can create and manage new databases. I hope today’s tutorial gives you enough confidence that you can try out NuoDB and checkout various administrative activities with the database. I am personally impressed with their dashboard related to various counters. For more information about how the NuoDB architecture works and what a Storage Manager or Transaction Engine does, check out this short video with NuoDB CTO Seth Proctor:  In the next blog post, we will try out the Explorer section of NuoDB, which allows us to run SQL queries and write SQL code.  Meanwhile, I strongly suggest you download and install NuoDB and get yourself familiar with the product.

• Gartner PCC: A Shovel & Some Ah-Ha's

  - by kellsey.ruppel

  When Gartner Vice President and leading analyst Whit Andrews kicked off the Gartner Portals, Content & Collaboration Summit on Monday, March 12 at the Gaylord Palms in Orlando, FL by bringing a shovel to the stage, eyebrows raised and a few thoughts went through my head. Either this guy plans to go help the construction workers outside construct that new pool at the Gaylord or he took a wrong turn and is at the wrong conference. Oh and how did he get that shovel through airport security? As Whit explained more his objective became more clear…take everything anyone has ever told you about portals and throw it out the window, as portals have evolved and times they are most certainly changing. The future Web is here, available not only on browsers but also via a broad spectrum of access points, including automobiles, consumer electronics and more and more mobile devices. Not merely prevalent, the future Web is also multimedia-driven and operates in real time, driven by mobility, social media, streaming video and other dynamic services. Applications and user experiences are in the midst of an evolution — from the early, simple mobile Web models to today’s Web 2.0 mobile apps and, ultimately, to a world of predominantly Web apps. Additionally, cloud services will forever change how portals and user experience are designed, built, delivered, sourced and managed. So what does this mean for you? Today’s organizations need software that will enable them to not just do their jobs, but to do it in a way that is familiar and easy for them.  What does this mean for IT? Use software and technology as an enabler, not as a roadblock. Overall, we had a great week in Orlando learning about how to improve the user experience, manage content explosion, launch social initiatives, transition to mobile environments and understand cloud and SaaS options.  We had some great conversations throughout the conference and at the Oracle booth. Lots of demonstrations were given of Oracle WebCenter Sites and Oracle Social Network. And as Christie mentioned earlier this week, our Vice President of Product Management and Strategy for WebCenter Loren Weinberg presented on the topic of customer engagement and talked about how organization’s relationships with their customers have fundamentally changed today and the resulting impact that has on their priorities.  Loren also talked about the importance of customer engagement, why that matters now more than ever, and what you can do to help your company or organization succeed in this new world. The question asked in every keynote and session was a simple one: What is your “ah-ha” moment? I personally had quite a few, some of which I’ve captured below. 70% of internal social initiatives eventually fail. By 2014, refusing to communicate with consumers via social media will be as harmful as ignoring emails/phone calls is today. Customer engagement = multi-channel + social & interactive + personal & relevant + optimized. If people choose to talk about your product/company/service, it's because it's remarkable. -- Seth Godin's keynote (one of the highlights of the conference!) The Web will become the primary method used for delivering content and applications to mobile devices. By 2015, 20% of smart phone users worldwide will conduct commerce using context-enriched services on a weekly basis.  86% of customers will pay more for a better customer experience. 6 P's of Quality User Experience. Product. Enabled by: People, Patterns, Process, Profit, Priorities. Did you attend the Gartner Summit? What were your ah-ha moments?

• What You Can Learn from the NFL Referee Lockout

  - by Christina McKeon

  American football is a lot like religion. The fans are devoted followers that take brand loyalty to a whole new level. These fans that worship their teams each week showed that they are powerful customers whose voice has an impact. Yesterday, these fans proved that their opinion could force the hand of a large and powerful institution. With a three-month NFL referee lockout that seemed like it was nowhere close to resolution, the Green Bay Packers and the Seattle Seahawks competed last Monday night. For those of you that might have been out of the news cycle the past few days, Green Bay lost the game due to a controversial call that many experts and analysts agree should have resulted in Green Bay winning the game. Outrage ensued. The NFL had pulled replacement referees from the high school ranks, and these replacements did not have the knowledge and experience to handle high intensity NFL games. Fans protested about their customer experience. Their anger-filled rants were heard in social media, in the headlines of newspapers, on radio, and on national TV. Suddenly, the NFL was moved to reach an agreement with the referees. That agreement was reached late in the night on Wednesday with many believing that the referees had the upper hand forcing the owners into submission. Some might argue that the referees benefited, not the fans. Since the fans wanted qualified and competent referees, I would say the fans did benefit. The referees are scheduled to return to the field this Sunday, so the fans got what they wanted. What can you learn from this negative customer experience? Customers are in control. NFL owners thought they were controlling this situation with the upper hand over referees. The owners figured out they weren’t in control when their fans reacted negatively. Customers can make or break you more now than ever before, which is why it is more important to connect with them, engage them in a personal manner, and create rewarding relationships. Protect your brand. Whether knowingly or unknowingly, the NFL put their brand and each team’s brand at risk with replacement referees. Think about each business decision you make, and how it may impact your brand at different points in time. A decision that results in a gain today could result in a larger loss down the road. Customer experience matters. The NFL likely foresaw declining revenues in ticket sales, merchandising, advertising, and other areas if the lockout continued. While fans primarily spoke with their minds in the days following the Green Bay debacle, their wallets would be the next things to speak. Customer experience directly affects your success and is one of the few areas where you can differentiate your business. What would you do if your brand got such negative attention? Would you be prepared to navigate such stormy waters? Would you be able to prevent such a fiasco? If you don’t have a good answer to these questions, consider joining us October 3-5, 2012 at the Oracle Customer Experience Summit in San Francisco. You’ll have the opportunity to learn even more about customer experience from industry experts such as best-selling author Seth Godin, Paul Hagen and Kerry Bodine from Forrester Research, Inc., George Kembel from the Stanford d.School, Bruce Temkin of The Temkin Group, and Gene Alvarez from Gartner Inc.. There will also be plenty of your peers and customer experience experts available for networking and discussions.

• Binding Image.Source to String in WPF ?

  I have below XAML code : <Window x:Class="WpfApplication1.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" DataContext="{Binding RelativeSource={RelativeSource Self}}" WindowStartupLocation="CenterScreen" Title="Window1" Height="300" Width="300"> <Grid> <Image x:Name="TestImage" Source="{Binding Path=ImageSource}" /> </Grid> </Window> Also, there is a method that makes an Image from a Base64 string : Image Base64StringToImage(string base64ImageString) { try { byte[] b; b = Convert.FromBase64String(base64ImageString); MemoryStream ms = new System.IO.MemoryStream(b); System.Drawing.Image img = System.Drawing.Image.FromStream(ms); ////////////////////////////////////////////// //convert System.Drawing.Image to WPF image System.Drawing.Bitmap bmp = new System.Drawing.Bitmap(img); IntPtr hBitmap = bmp.GetHbitmap(); System.Windows.Media.ImageSource imageSource = System.Windows.Interop.Imaging.CreateBitmapSourceFromHBitmap(hBitmap, IntPtr.Zero, Int32Rect.Empty, BitmapSizeOptions.FromEmptyOptions()); Image wpfImage = new Image(); wpfImage.Source = imageSource; wpfImage.Width = wpfImage.Height = 16; ////////////////////////////////////////////// return wpfImage; } catch { Image img1 = new Image(); img1.Source = new BitmapImage(new Uri(@"/passwordManager;component/images/TreeView/empty-bookmark.png", UriKind.Relative)); img1.Width = img1.Height = 16; return img1; } } Now, I'm gonna bind TestImage to the output of Base64StringToImage method.

• Scrolling down to next element via keypress & scrollTo plugin - jQuery

  - by lyrae

  I am using jQuery's scrollTo plugin to scroll up and down my page, using UP arrow and DOWN arrow. i have a bunch of div with class "screen", as so: <div class="screen-wrapper">...</div> What I am trying to do is, when i press UP or DOWN, the window scrolls to the next, or previous div with class of "screen". I have the keypresses taken care of. According to the plugin docs, to scroll a window, you use $.scrollTo(...); Here's the code I have: $(document).keypress(function(e){ switch (e.keyCode) { case 40: // down n = $('.screen-wrapper').next() $.scrollTo( n, 800 ); break; case 38: // up break; case 37: // left break; case 39: // right break; } }); And if it helps, here's the HTML div. I have a few of these on the page, and essentially, am trying to scroll to next one by pressing down arrow: <div class='screen-wrapper'> <div class='screen'> <div class="sections"> <ul> <li><img src="images/portfolio/sushii-1.png " /></li> <li><img src="images/portfolio/sushii-2.png" /></li> <li><img src="images/portfolio/sushii-3.png" /></li> </ul> </div> <div class="next"></div> <div class="prev"></div> </div> And also if it needed, I can provide a link where this is being used if it'll help someone get a better idea. edit And, i forgot to mention what the real question here is. The question/problem is that it won't scroll down past the first element, as seth mentioned.

  I'm asked to find a 2 approximate solution to this problem: You’re consulting for an e-commerce site that receives a large number of visitors each day. For each visitor i, where i € {1, 2 ..... n}, the site has assigned a value v[i], representing the expected revenue that can be obtained from this customer. Each visitor i is shown one of m possible ads A1, A2 ..... An as they enter the site. The site wants a selection of one ad for each customer so that each ad is seen, overall, by a set of customers of reasonably large total weight. Thus, given a selection of one ad for each customer, we will define the spread of this selection to be the minimum, over j = 1, 2 ..... m, of the total weight of all customers who were shown ad Aj. Example Suppose there are six customers with values 3, 4, 12, 2, 4, 6, and there are m = 3 ads. Then, in this instance, one could achieve a spread of 9 by showing ad A1 to customers 1, 2, 4, ad A2 to customer 3, and ad A3 to customers 5 and 6. The ultimate goal is to find a selection of an ad for each customer that maximizes the spread. Unfortunately, this optimization problem is NP-hard (you don’t have to prove this). So instead give a polynomial-time algorithm that approximates the maximum spread within a factor of 2. The solution I found is the following: Order visitors values in descending order Add the next visitor value (i.e. assign the visitor) to the Ad with the current lowest total value Repeat This solution actually seems to always find the optimal solution, or I simply can't find a counterexample. Can you find it? Is this a non-polinomial solution and I just can't see it?

• Combining two queries on same table

  - by user1830856

  I've looked through several previous questions but I am struggling to apply the solutions to my specific example. I am having trouble combining query 1 and query 2. My query originally returned (amongst other details) the values "SpentTotal" and "UnderSpent" for all members/users for the current month. My issue has been adding two additional columns to this original quert that will return JUST these two columns (Spent and Overspent) but for the previous months data Original Query #1: set @BPlanKey = '##CURRENTMONTH##' EXECUTE @RC = Minimum_UpdateForPeriod @BPlanKey SELECT cm.clubaccountnumber, bp.Description , msh.PeriodMinObligation, msh.SpentTotal, msh.UnderSpent, msh.OverSpent, msh.BilledDate, msh.PeriodStartDate, msh.PeriodEndDate, msh.OverSpent FROM MinimumSpendHistory msh INNER JOIN BillPlanMinimums bpm ON msh.BillingPeriodKey = @BPlanKey and bpm.BillPlanMinimumKey = msh.BillPlanMinimumKey INNER JOIN BillPlans bp ON bp.BillPlanKey = bpm.BillPlanKey INNER JOIN ClubMembers cm ON cm.parentmemberkey is null and cm.ClubMemberKey = msh.ClubMemberKey order by cm.clubaccountnumber asc, msh.BilledDate asc Query #2, query of all columns for PREVIOUS month, but I only need two (spent and over spent), added to the query from above, joined on the customer number: set @BPlanKeyLastMo = '##PREVMONTH##' EXECUTE @RCLastMo = Minimum_UpdateForPeriod @BPlanKeyLastMo SELECT cm.clubaccountnumber, bp.Description , msh.PeriodMinObligation, msh.SpentTotal, msh.UnderSpent, msh.OverSpent, msh.BilledDate, msh.PeriodStartDate, msh.PeriodEndDate, msh.OverSpent FROM MinimumSpendHistory msh INNER JOIN BillPlanMinimums bpm ON msh.BillingPeriodKey = @BPlanKeyLastMo and bpm.BillPlanMinimumKey = msh.BillPlanMinimumKey INNER JOIN BillPlans bp ON bp.BillPlanKey = bpm.BillPlanKey INNER JOIN ClubMembers cm ON cm.parentmemberkey is null and cm.ClubMemberKey = msh.ClubMemberKey order by cm.clubaccountnumber asc, msh.BilledDate asc Big thank you to any and all that are willing to lend their help and time.

• Highlights from the Oracle Customer Experience Summit @ OpenWorld

  - by Richard Lefebvre

  The Oracle Customer Experience Summit was the first-ever event covering the full breadth of Oracle's CX portfolio -- Marketing, Sales, Commerce, and Service. The purpose of the Summit was to articulate the customer experience imperative and to showcase the suite of Oracle products that can help our customers create the best possible customer experience. This topic has always been a very important one, but now that there are so many alternative companies to do business with and because people have such public ways to voice their displeasure, it's necessary for vendors to have multiple listening posts in place to gauge consumer sentiment. They need to know what is going on in real time and be able to react quickly to turn negative situations into positive ones. Those can then be shared in a social manner to enhance the brand and turn the customer into a repeat customer. The Summit was focused on Oracle's portfolio of products and entirely dedicated to customers who are committed to building great customer experiences within their businesses. Rather than DBAs, the attendees were business people looking to collaborate with other like-minded experts and find out how Oracle can help in terms of technology, best practices, and expertise. The event was at the Westin St. Francis Hotel in San Francisco as part of Oracle OpenWorld. We had eight hundred people attend, which was great for the first year. Next year, there's no doubt in my mind, we can raise that number to 5,000. Alignment and Logic Oracle's Customer Experience portfolio is made up of a combination of acquired and organic products owned by many people who are new to Oracle. We include homegrown Fusion CRM, as well as RightNow, Inquira, OPA, Vitrue, ATG, Endeca, and many others. The attendees knew of the acquisitions, so naturally they wanted to see how the products all fit together and hear the logic behind the portfolio. To tell them about our alignment, we needed to be aligned. To accomplish that, a cross functional team at Oracle agreed on the messaging so that every single Oracle presenter could cover the big picture before going deep into a product or topic. Talking about the full suite of products in one session produced overflow value for other products. And even though this internal coordination was a huge effort, everyone saw the value for our customers and for our long-term cooperation and success. Keynotes, Workshops, and Tents of Innovation We scored by having Seth Godin as our keynote speaker ? always provocative and popular. The opening keynote was a session orchestrated by Mark Hurd, Anthony Lye, and me. Mark set the stage by giving real-world examples of bad customer experiences, Anthony clearly articulated the business imperative for addressing these experiences, and I brought it all to life by taking the audience around the Customer Lifecycle and showing demos and videos, with partners included at each of the stops around the lifecycle. Brian Curran, a VP for RightNow Product Strategy, presented a session that was in high demand called The Economics of Customer Experience. People loved hearing how to build a business case and justify the cost of building a better customer experience. John Kembel, another VP for RightNow Product Strategy, held a workshop that customers raved about. It was based on the journey mapping methodology he created, which is a way to talk to customers about where they want to make improvements to their customers' experiences. He divided the audience into groups led by facilitators. Each person had the opportunity to engage with experts and peers and construct some real takeaways. The conference hotel was across from Union Square so we used that space to set up Innovation Tents. During the day we served lunch in the tents and partners showed their different innovative ideas. It was very interesting to see all the technologies and advancements. It also gave people a place to mix and mingle and to think about the fringe of where we could all take these ideas. Product Portfolio Plus Thought Leadership Of course there is always room for improvement, but the feedback on the format of the conference was positive. Ninety percent of the sessions had either a partner or a customer teamed with an Oracle presenter. The presentations weren't dry, one-way information dumps, but more interactive. I just followed up with a CEO who attended the conference with his Head of Marketing. He told me that they are using John Kembel's journey mapping methodology across the organization to pull people together. This sort of thought leadership in these highly competitive areas gives Oracle permission to engage around the technology. We have to differentiate ourselves and it's harder to do on the product side because everyone looks the same on paper. But on thought leadership ? we can, and did, take some really big steps.

• Eclipse: How to convert a web project into an AspectJ project and weave and run it using the AJDT pl

  - by Kent

  What I want to do: I want to use the @Configured annotation with Spring. It requires AspectJ to be enabled. I thought that using the AJDT plugin for compile time weaving would solve this problem. Before installing the plug in the dependencies which were supposed to be injected into my @Configured object remained null. What I have done: Installed the AJDT: AspectJ Development Tools plug in for Eclipse 3.4. Right clicked on my web project and converted it into a AspectJ project. Enabled compile time weaving. What doesn't work: When I start the Tomcat 6 server now, I get an exception*. Other information: I haven't configured anything in the AspectJ Build and AspectJ Compiler parts of the project properties. JDT Weaving under Preferences says weaving is enabled. I still have Java build path and Java Compiler under project properties. And they look like I previously configured them (while the above two new entries are not configured). The icon of my @Configured object file looks like any other file (i.e. no indication of any aspect or such, which I think there should be). The file name is MailNotification.java (and not .aj), but I guess it should still work as I'm using a Spring annotation for AspectJ? I haven't found any tutorial or similar which teaches: How to turn a Spring web application project into an AspectJ project and weave aspects into the files using the AJDT plugin, all within Eclipse 3.4. If there is anything like that out there I would be very interested in knowing about it. What I would like to know: Where to go from here? I just want to use the @Configured annotation of Spring. I'm also using @Transactional which I think also needs AspectJ. If it is possible I would like to study AspectJ as little as possible as long as my needs are met. The subject seems interesting, but huge, all I want to do is use the above two mentioned Spring annotations. *** Exception when Tomcat 6 is started: Caused by: java.lang.IllegalStateException: ClassLoader [org.apache.catalina.loader.WebappClassLoader] does NOT provide an 'addTransformer(ClassFileTransformer)' method. Specify a custom LoadTimeWeaver or start your Java virtual machine with Spring's agent: -javaagent:spring-agent.jar at org.springframework.context.weaving.DefaultContextLoadTimeWeaver.setBeanClassLoader(DefaultContextLoadTimeWeaver.java:82) at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.initializeBean(AbstractAutowireCapableBeanFactory.java:1322) at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.doCreateBean(AbstractAutowireCapableBeanFactory.java:473) ... 41 more

• SQL – Migrate Database from SQL Server to NuoDB – A Quick Tutorial

  - by Pinal Dave

  Data is growing exponentially and every organization with growing data is thinking of next big innovation in the world of Big Data. Big data is a indeed a future for every organization at one point of the time. Just like every other next big thing, big data has its own challenges and issues. The biggest challenge associated with the big data is to find the ideal platform which supports the scalability and growth of the data. If you are a regular reader of this blog, you must be familiar with NuoDB. I have been working with NuoDB for a while and their recent release is the best thus far. NuoDB is an elastically scalable SQL database that can run on local host, datacenter and cloud-based resources. A key feature of the product is that it does not require sharding (read more here). Last week, I was able to install NuoDB in less than 90 seconds and have explored their Explorer and Admin sections. You can read about my experiences in these posts: SQL – Step by Step Guide to Download and Install NuoDB – Getting Started with NuoDB SQL – Quick Start with Admin Sections of NuoDB – Manage NuoDB Database SQL – Quick Start with Explorer Sections of NuoDB – Query NuoDB Database Many SQL Authority readers have been following me in my journey to evaluate NuoDB. One of the frequently asked questions I’ve received from you is if there is any way to migrate data from SQL Server to NuoDB. The fact is that there is indeed a way to do so and NuoDB provides a fantastic tool which can help users to do it. NuoDB Migrator is a command line utility that supports the migration of Microsoft SQL Server, MySQL, Oracle, and PostgreSQL schemas and data to NuoDB. The migration to NuoDB is a three-step process: NuoDB Migrator generates a schema for a target NuoDB database It loads data into the target NuoDB database It dumps data from the source database Let’s see how we can migrate our data from SQL Server to NuoDB using a simple three-step approach. But before we do that we will create a sample database in MSSQL and later we will migrate the same database to NuoDB: Setup Step 1: Build a sample data CREATE DATABASE [Test]; CREATE TABLE [Department]( [DepartmentID] [smallint] NOT NULL, [Name] VARCHAR(100) NOT NULL, [GroupName] VARCHAR(100) NOT NULL, [ModifiedDate] [datetime] NOT NULL, CONSTRAINT [PK_Department_DepartmentID] PRIMARY KEY CLUSTERED ( [DepartmentID] ASC ) ) ON [PRIMARY]; INSERT INTO Department SELECT * FROM AdventureWorks2012.HumanResources.Department; Note that I am using the SQL Server AdventureWorks database to build this sample table but you can build this sample table any way you prefer. Setup Step 2: Install Java 64 bit Before you can begin the migration process to NuoDB, make sure you have 64-bit Java installed on your computer. This is due to the fact that the NuoDB Migrator tool is built in Java. You can download 64-bit Java for Windows, Mac OSX, or Linux from the following link: http://java.com/en/download/manual.jsp. One more thing to remember is that you make sure that the path in your environment settings is set to your JAVA_HOME directory or else the tool will not work. Here is how you can do it: Go to My Computer >> Right Click >> Select Properties >> Click on Advanced System Settings >> Click on Environment Variables >> Click on New and enter the following values. Variable Name: JAVA_HOME Variable Value: C:\Program Files\Java\jre7 Make sure you enter your Java installation directory in the Variable Value field. Setup Step 3: Install JDBC driver for SQL Server. There are two JDBC drivers available for SQL Server.  Select the one you prefer to use by following one of the two links below: Microsoft JDBC Driver jTDS JDBC Driver In this example we will be using jTDS JDBC driver. Once you download the driver, move the driver to your NuoDB installation folder. In my case, I have moved the JAR file of the driver into the C:\Program Files\NuoDB\tools\migrator\jar folder as this is my NuoDB installation directory. Now we are all set to start the three-step migration process from SQL Server to NuoDB: Migration Step 1: NuoDB Schema Generation Here is the command I use to generate a schema of my SQL Server Database in NuoDB. First I go to the folder C:\Program Files\NuoDB\tools\migrator\bin and execute the nuodb-migrator.bat file. Note that my database name is ‘test’. Additionally my username and password is also ‘test’. You can see that my SQL Server database is running on my localhost on port 1433. Additionally, the schema of the table is ‘dbo’. nuodb-migrator schema –source.driver=net.sourceforge.jtds.jdbc.Driver –source.url=jdbc:jtds:sqlserver://localhost:1433/ –source.username=test –source.password=test –source.catalog=test –source.schema=dbo –output.path=/tmp/schema.sql The above script will generate a schema of all my SQL Server tables and will put it in the folder C:\tmp\schema.sql . You can open the schema.sql file and execute this file directly in your NuoDB instance. You can follow the link here to see how you can execute the SQL script in NuoDB. Please note that if you have not yet created the schema in the NuoDB database, you should create it before executing this step. Step 2: Generate the Dump File of the Data Once you have recreated your schema in NuoDB from SQL Server, the next step is very easy. Here we create a CSV format dump file, which will contain all the data from all the tables from the SQL Server database. The command to do so is very similar to the above command. Be aware that this step may take a bit of time based on your database size. nuodb-migrator dump –source.driver=net.sourceforge.jtds.jdbc.Driver –source.url=jdbc:jtds:sqlserver://localhost:1433/ –source.username=test –source.password=test –source.catalog=test –source.schema=dbo –output.type=csv –output.path=/tmp/dump.cat Once the above command is successfully executed you can find your CSV file in the C:\tmp\ folder. However, you do not have to do anything manually. The third and final step will take care of completing the migration process. Migration Step 3: Load the Data into NuoDB After building schema and taking a dump of the data, the very next step is essential and crucial. It will take the CSV file and load it into the NuoDB database. nuodb-migrator load –target.url=jdbc:com.nuodb://localhost:48004/mytest –target.schema=dbo –target.username=test –target.password=test –input.path=/tmp/dump.cat Please note that in the above script we are now targeting the NuoDB database, which we have already created with the name of “MyTest”. If the database does not exist, create it manually before executing the above script. I have kept the username and password as “test”, but please make sure that you create a more secure password for your database for security reasons. Voila!  You’re Done That’s it. You are done. It took 3 setup and 3 migration steps to migrate your SQL Server database to NuoDB.  You can now start exploring the database and build excellent, scale-out applications. In this blog post, I have done my best to come up with simple and easy process, which you can follow to migrate your app from SQL Server to NuoDB. Download NuoDB I strongly encourage you to download NuoDB and go through my 3-step migration tutorial from SQL Server to NuoDB. Additionally here are two very important blog post from NuoDB CTO Seth Proctor. He has written excellent blog posts on the concept of the Administrative Domains. NuoDB has this concept of an Administrative Domain, which is a collection of hosts that can run one or multiple databases.  Each database has its own TEs and SMs, but all are managed within the Admin Console for that particular domain. http://www.nuodb.com/techblog/2013/03/11/getting-started-provisioning-a-domain/ http://www.nuodb.com/techblog/2013/03/14/getting-started-running-a-database/ Reference: Pinal Dave (http://blog.sqlauthority.com) Filed under: Big Data, PostADay, SQL, SQL Authority, SQL Query, SQL Server, SQL Tips and Tricks, T SQL, Technology Tagged: NuoDB

• My Thoughts On the Xbox 180

  - by Chris Gardner

  Originally posted on: http://geekswithblogs.net/freestylecoding/archive/2013/06/21/my-thoughts-on-the-xbox-180.aspx Everyone seems to be putting their 0.00237 cents into the wishing well over Microsoft's recent decision to reverse the DRM policy on the Xbox One. However, there have been a few issues that nobody has touched. As such, I have decided to dig 0.00237 cents out of my pocket. First, let me be clear about this point. I do not support the decision to reverse the DRM policy on the Xbox One. I wanted that point to be expressed first and unambiguously. I will say it again. I do not support the decision to reverse the DRM policy on the Xbox One. Now that I have that out of the way, let me go into my rationale. This decision removes most of the cool features that enticed me to pre-order the console. No, I didn't cancel my pre-order. There is still five months before the release of the console, and there is still a plethora of information that we, as consumers, do not have. With that, it should be noted that much of the talk in this post is speculation and rhetoric. I do not have any insider information that you do not possess. The persistent connection would have allowed the console to do many of the functions for which we have been begging. That demo where someone was playing Ryse, seamlessly accepted a multiplayer challenge in Killer Instinct, played the match (and a rematch,) and then jumped back into Ryse. That's gone, if you bought the game on disc. The new, DRM free system will require the disc in the system to play a game. That bullet point where one Xbox Live account could have up to 10 slave accounts so families could play together, no matter where they were located. That's gone as well. The promise of huge, expansive, dynamically changing worlds that was brought to us with the power of cloud computing. Well, "the people" didn't want there to be a forced, persistent connection. As such, developers can't rely on a connection and, as such, that feature is gone. This is akin to the removal of the hard drive on the Xbox 360. The list continues, but the enthusiast press has enumerated the list far better than I wish. All of this is because the Xbox team saw the HUGE success of Steam and decided to borrow a few ideas. Yes, Steam. The service that everyone hated for the first six months (for the same reasons the Xbox One is getting flack.) There was an initial growing pain. However, it is now lauded as the way games distribution should be handled. Unless you are Microsoft. I do find it curious that many of the features were originally announced for the PS4 during its unveiling. However, much of that was left strangely absent for Sony's E3 press conference. Instead, we received a single, static slide that basically said the exact opposite of Microsoft's plans. It is not farfetched to believe that slide came into existence during the approximately seven hours between the two media briefings. The thing that majorly annoys me over this whole kerfuffle is that the single thing that caused the call to arms is, really, not an issue. Microsoft never said they were going to block used sales. They said it was up to the publisher to make that decision. This would have allowed publishers to reclaim some of the costs of development in subsequent sales of the product. If you sell your game to GameStop for 7 USD, GameStop is going to sell it for 55 USD. That is 48 USD pure profit for them. Some publishers asked GameStop for a small cut. Was this a huge, money grubbing scheme? Well, yes, but the idea was that they have to handle server infrastructure for dormant accounts, etc. Of course, GameStop flatly refused, and the Online Pass was born. Fortunately, this trend didn’t last, and most publishers have stopped the practice. The ability to sell "licenses" has already begun to be challenged. Are you living in the EU? If so, companies must allow you to sell digital property. With this precedent in place, it's only a matter of time before other areas follow suit. If GameStop were smart, they should have immediately contacted every publisher out there to get the rights to become a clearing house for these licenses. Then, they keep their business model and could reduce their brick and mortar footprint. The digital landscape is changing. We need to not block this process. As Seth MacFarlane best said "Some issues are so important that you should drag people kicking and screaming." I believe this was said on an episode of Real Time with Bill Maher about the issue of Gay Marriages. Much like the original source, this is an issue that we need to drag people to the correct, progressive position. Microsoft, as a company, actually has the resources to weather the transition period. They have a great pool of first and second party developers that can leverage this new framework to prove the validity. Over time, the third party developers will get excited to use these tools. As an old C++ guy, I resisted C# for years. Now, I think it's one of the best languages I've ever used. I have a server room and a Co-Lo full of servers, so I originally didn't see the value in Azure. Now, I wish I could move every one of my projects into the cloud. I still LOVE getting physical packaging, which my music and games collection will proudly attest. However, I have started to see the value in pure digital, and have found ways to integrate this into the ways I consume those products. I can, honestly, understand how some parts of the population would be very apprehensive about this new landscape. There were valid arguments about people with no internet access. There are ways to combat these problems. These methods do not require us to throw the baby out with the bathwater. However, the number of people in the computer industry that I have seen cry foul is truly appalling. We are the forward looking people that help show how technology can improve people's lives. If we can't see the value of the brief pain involved with an exciting new ecosystem, than who will?
