    - by Archagon
    What are some of your favorite papers and publications that closely relate to game programming? I'm particularly looking for examples that are well-written and illustrated, and/or have had a profound influence on the industry. (Here's one example: in this GDC talk, Bungie's David Aldridge mentions that a paper called "The TRIBES Engine Networking Model" was the starting point for Halo's network code.)

  • Design for XML mapping scenarios between two different systems [on hold]

    - by deepak_prn
    Mapping XML fields between two systems is a mundane routine in integration scenarios. I am trying to make the design documents look better and provide clear understanding to the developers especially when we do not use XSLT or any other IDE such as jDeveloper or eclipse plugins. I want it to be a high level design but at the same time talk in developer's language. So that there is no requirements that slip under the crack. For example, one of the scenarios goes: the store cashier sells an item, the transaction data is sent to Data management system. Now, I am writing a functional design for the scenario which deals with mapping XML fields between our system and the data management system. Question : I was wondering if some one had to deal with mapping XML fields between two systems? (without XSLT being involved) and if you used a table to represent the fields mapping (example is below) or any other visualization tool which does not break the bank ? I am trying to find out if there is a better way to represent XML mapping in your design documents. The widely accepted and used method seems to be using a simple table such as in the picture to illustrate the mapping. I am wondering if there are alternate ways/ tools to represent such as in Altova:

  • University Choices For Programmers

    - by Michael
    I've noticed that the majority of eminent hackers seem to have come from prestigious universities. How true is this, and is it important to have this type of background to become prominent in the programming field? I don't necessarily have the means to attend a top school, but I have the desire to work among the best. Is it possible without coming from a highly-regarded program? Is graduate study at a good school more important than undergraduate in this regard?

  • 8-Puzzle Solution executes infinitely [migrated]

    - by Ashwin
    I am looking for a solution to 8-puzzle problem using the A* Algorithm. I found this project on the internet. Please see the files - proj1 and EightPuzzle. The proj1 contains the entry point for the program(the main() function) and EightPuzzle describes a particular state of the puzzle. Each state is an object of the 8-puzzle. I feel that there is nothing wrong in the logic. But it loops forever for these two inputs that I have tried : {8,2,7,5,1,6,3,0,4} and {3,1,6,8,4,5,7,2,0}. Both of them are valid input states. What is wrong with the code? Note For better viewing copy the code in a Notepad++ or some other text editor(which has the capability to recognize java source file) because there are lot of comments in the code. Since A* requires a heuristic, they have provided the option of using manhattan distance and a heuristic that calculates the number of misplaced tiles. And to ensure that the best heuristic is executed first, they have implemented a PriorityQueue. The compareTo() function is implemented in the EightPuzzle class. The input to the program can be changed by changing the value of p1d in the main() function of proj1 class. The reason I am telling that there exists solution for the two my above inputs is because the applet here solves them. Please ensure that you select 8-puzzle from teh options in the applet. EDITI gave this input {0,5,7,6,8,1,2,4,3}. It took about 10 seconds and gave a result with 26 moves. But the applet gave a result with 24 moves in 0.0001 seconds with A*. For quick reference I have pasted the the two classes without the comments : EightPuzzle import java.util.*; public class EightPuzzle implements Comparable <Object> { int[] puzzle = new int[9]; int h_n= 0; int hueristic_type = 0; int g_n = 0; int f_n = 0; EightPuzzle parent = null; public EightPuzzle(int[] p, int h_type, int cost) { this.puzzle = p; this.hueristic_type = h_type; this.h_n = (h_type == 1) ?

  • Low hanging fruit where "a sufficiently smart compiler" is needed to get us back to Moore's Law?

    - by jamie
    Paul Graham argues that: It would be great if a startup could give us something of the old Moore's Law back, by writing software that could make a large number of CPUs look to the developer like one very fast CPU. ... The most ambitious is to try to do it automatically: to write a compiler that will parallelize our code for us. There's a name for this compiler, the sufficiently smart compiler, and it is a byword for impossibility. But is it really impossible? Can someone provide a concrete example where a paralellizing compiler would solve a pain point? Web-apps don't appear to be a problem: just run a bunch of Node processes. Real-time raytracing isn't a problem: the programmers are writing multi-threaded, SIMD assembly language quite happily (indeed, some might complain if we make it easier!). The holy grail is to be able to accelerate any program, be it MySQL, Garage Band, or Quicken. I'm looking for a middle ground: is there a real-world problem that you have experienced where a "smart-enough" compiler would have provided a real benefit, i.e that someone would pay for?

To bring greater efficiency and centralized project management capabilities to its operations, CPqD chose Oracle’s Primavera P6 Enterprise Project Portfolio Management. “Oracle Primavera is an essential tool for our day-to-day business, and I notice the effort Oracle makes to constantly innovate and to add more functionality in an increasingly shorter period of time,” says Márcio Alexandre da Silva, IT department project coordinator, CPqD. He explains that before CPqD implemented the Oracle solution, the company did not have a corporate view of projects. “Our project monitoring was decentralized and restricted to each coordinator,” the project coordinator says. “With the Oracle solution, we achieved actual shared management, more control, and budgets that stay within projections.” Among the benefits that CPqD now enjoys are The ability to more effectively identify how employees are allocated, enabling managers to increase or reduce resources based on project scope, as well as secure the resources required for unexpected projects and demands A 75 percent reduction in the time it takes to collect project data and indicators—automated and centralized collection means project coordinators no longer have to manually compile information that was spread among various systems Read the complete CPqD company snapshot Read more in the October Edition of the quarterly Information InDepth EPPM Newsletter Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin-top:0in; mso-para-margin-right:0in; mso-para-margin-bottom:10.0pt; mso-para-margin-left:0in; line-height:115%; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;}

  • Operating systems -- using minimum number of semaphores

    - by stackuser
    The three cooperating processes all read data from the same input device. Each process, when it gets the input device, must read two consecutive data. I want to use mutual exclusion to do this. The declaration and initialization that I think would work here are: semaphore s=1 sa1 = 0, sa2 = 0, sb1 = 0, sb2 = 0, sc1 = 0, sc2 = 0 I'd like to use semaphores to synchronize the following processes: P1: P2: P3: input(a1,a2) input (b1,b2) input(c1,c2) Y=a1+c1 W=b2+c2 Z=a2+b1 Print (X) X=Z-Y+W I'm wondering how to use the minimum number of semaphores to solve this.

  • Project Management Helps AmeriCares Deliver International Aid

    - by Sylvie MacKenzie, PMP
    Excerpt from PROFIT - ORACLE - by Alison Weiss Handle with Care Sound project management helps AmeriCares bring international aid to those in need. The stakes are always high for AmeriCares. On a mission to restore health and save lives during times of disaster, the nonprofit international relief and humanitarian aid organization delivers donated medicines, medical supplies, and humanitarian aid to people in the U.S. and around the globe. Founded in 1982 with the express mission of responding as quickly and efficiently as possible to help people in need, the Stamford, Connecticut-based AmeriCares has delivered more than US$10.5 billion in aid to 147 countries over the past three decades. Launch the Slideshow “It’s critically important to us that we steward all the donations and that the medical supplies and medicines get to people as quickly as possible with no loss,” says Kate Sears, senior vice president for finance and technology at AmeriCares. “Whether we’re shipping IV solutions to victims of cholera in Haiti or antibiotics to Somali famine victims, we need to get the medicines there sooner because it means more people will be helped and lives improved or even saved.” Ten years ago, the tracking systems used by AmeriCares associates were paper-based. In recent years, staff started using spreadsheets, but the tracking processes were not standardized between teams. “Every team was tracking completely different information,” says Megan McDermott, senior associate, Sub-Saharan Africa partnerships, at AmeriCares. “It was just a few key things. For example, we tracked the date a shipment was supposed to arrive and the date we got reports from our partner that a hospital received aid on their end.” While the data was accurate, much detail was being lost in the process. AmeriCares management knew it could do a better job of tracking this enterprise data and in 2011 took a significant step by implementing Oracle’s Primavera P6 Professional Project Management. “It’s a comprehensive solution that has helped us improve the monitoring and controlling processes. It has allowed us to do our distribution better,” says Sears. In addition, the implementation effort has been a change agent, helping AmeriCares leadership rethink project management across the entire organization. Initially, much of the focus was on standardizing processes, but staff members also learned the importance of thinking proactively to prevent possible problems and evaluating results to determine if goals and objectives are truly being met. Such data about process efficiency and overall results is critical not only to AmeriCares staff but also to the donors supporting the organization’s life-saving missions. Efficiency Saves Lives One of AmeriCares’ core operations is to gather product donations from the private sector, establish where the most-urgent needs are, and solicit monetary support to send the aid via ocean cargo or airlift to welfare- and health-oriented nongovernmental organizations, hospitals, health networks, and government ministries based in areas in need. In 2011 alone, AmeriCares sent more than 3,500 shipments to 95 countries in response to both ongoing humanitarian needs and more than two dozen emergencies, including deadly tornadoes and storms in the U.S. and the devastating tsunami in Japan. When it comes to nonprofits in general, donors want to know that the charitable organizations they support are using funds wisely. Typically, nonprofits are evaluated by donors in terms of efficiency, an area where AmeriCares has an excellent reputation: 98 percent of expenses go directly to supporting programs and less than 2 percent represent administrative and fundraising costs. Donors, however, should look at more than simple efficiency, says Peter York, senior partner and chief research and learning officer at TCC Group, a nonprofit consultancy headquartered in New York, New York. They should also look at whether organizations have the systems in place to sustain their missions and continue to thrive. An expert on nonprofit organizational management, York has spent years studying sustainable charitable organizations. He defines them as nonprofits that are able to achieve the ongoing financial support to stay relevant and continue doing core mission work. In his analysis of well over 2,500 larger nonprofits, York has found that many are not sustaining, and are actually scaling back in size. “One of the biggest challenges of nonprofit sustainability is the general public’s perception that every dollar donated has to go only to the delivery of service,” says York. “What our data shows is that there are some fundamental capacities that have to be there in order for organizations to sustain and grow.” York’s research highlights the importance of data-driven leadership at successful nonprofits. “You’ve got to have the tools, the systems, and the technologies to get objective information on what you do, the people you serve, and the results you’re achieving,” says York. “If leaders don’t have the knowledge and the data, they can’t make the strategic decisions about programs to take organizations to the next level.” Historically, AmeriCares associates have used time-tested and cost-effective strategies to ship and then track supplies from donation to delivery to their destinations in designated time frames. When disaster strikes, AmeriCares ships by air and generally pulls out all the stops to deliver the most urgently needed aid within the first few days and weeks. Then, as situations stabilize, AmeriCares turns to delivering sea containers for the postemergency and ongoing aid so often needed over the long term. According to McDermott, getting a shipment out the door is fairly complicated, requiring as many as five different AmeriCares teams collaborating together. The entire process can take months—from when products are received in the warehouse and deciding which recipients to allocate supplies to, to getting customs and governmental approvals in place, actually shipping products, and finally ensuring that the products are received in-country. Delivering that aid is no small affair. “Our volume exceeds half a billion dollars a year worth of donated medicines and medical supplies, so it’s a sizable logistical operation to bring these products in and get them out to the right place quickly to have the most impact,” says Sears. “We really pride ourselves on our controls and efficiencies.” Adding to that complexity is the fact that the longer it takes to deliver aid, the more dire the human need can be. Any time AmeriCares associates can shave off the complicated aid delivery process can translate into lives saved. “It’s really being able to track information consistently that will help us to see where are the bottlenecks and where can we work on improving our processes,” says McDermott. Setting a Standard Productivity and information management improvements were key objectives for AmeriCares when staff began the process of implementing Oracle’s Primavera solution. But before configuring the software, the staff needed to take the time to analyze the systems already in place. According to Greg Loop, manager of database systems at AmeriCares, the organization received guidance from several consultants, including Rich D’Addario, consulting project manager in the Primavera Global Business Unit at Oracle, who was instrumental in shepherding the critical requirements-gathering phase. D’Addario encouraged staff to begin documenting shipping processes by considering the order in which activities occur and which ones are dependent on others to get accomplished. This exercise helped everyone realize that to be more efficient, they needed to keep track of shipments in a more standard way. “The staff didn’t recognize formal project management methodology,” says D’Addario. “But they did understand what the most important things are and that if they go wrong, an entire project can go off course.” Before, if a boatload of supplies was being sent to Haiti and there was a problem somewhere, a lot of time was taken up finding out where the problem was—because staff was not tracking things in a standard way. As a result, even more time was needed to find possible solutions to the problem and alert recipients that the aid might be delayed. “For everyone to put on the project manager hat and standardize the way every single thing is done means that now the whole organization is on the same page as to what needs to occur from the time a hurricane hits Haiti and when a boat pulls in to unload supplies,” says D’Addario. With so much care taken to put a process foundation firmly in place, configuring the Primavera solution was actually quite simple. Specific templates were set up for different types of shipments, and dashboards were implemented to provide executives with clear overviews of every project in the system. AmeriCares’ Loop reports that system planning, refining, and testing, followed by writing up documentation and training, took approximately four months. The system went live in spring 2011 at AmeriCares’ Connecticut headquarters. While the nonprofit has an international presence, with warehouses in Europe and offices in Haiti, India, Japan, and Sri Lanka, most donated medicines come from U.S. entities and are shipped from the U.S. out to the rest of the world. In addition, all shipments are tracked from the U.S. office. AmeriCares doesn’t expect the Primavera system to take months off the shipping time, especially for sea containers. However, any time saved is still important because it will allow aid to be delivered to people more quickly at a lower overall cost. “If we can trim a day or two here or there, that can translate into lives that we’re saving, especially in emergency situations,” says Sears. A Cultural Change Beyond the measurable benefits that come with IT-driven process improvement, AmeriCares management is seeing a change in culture as a result of the Primavera project. One change has been treating every shipment of aid as a project, and everyone involved with facilitating shipments as a project manager. “This is a revolutionary concept for us,” says McDermott. “Before, we were used to thinking we were doing logistics—getting a container from point A to point B without looking at it as one project and really understanding what it meant to manage it.” AmeriCares staff is also happy to report that collaboration within the organization is much more efficient. When someone creates a shipment in the Primavera system, the same shared template is used, which means anyone can log in to the system to see the status of a shipment. Knowledgeable staff can access a shipment project to help troubleshoot a problem. Management can easily check the status of projects across the organization. “Dashboards are really useful,” says McDermott. “Instead of going into the details of each project, you can just see the high-level real-time information at a glance.” The new system is helping team members focus on proactively managing shipments rather than simply reacting when problems occur. For example, when a container is shipped, documents must be included for customs clearance. Now, the shipping template has built-in reminders to prompt team members to ask for copies of these documents from freight forwarders and to follow up with partners to discover if a shipment is on time. In the past, staff may not have worked on securing these documents until they’d been notified a shipment had arrived in-country. Another benefit of capturing and adopting best practices within the Primavera system is that staff training is easier. “Capturing the processes in documented steps and milestones allows us to teach new staff members how to do their jobs faster,” says Sears. “It provides them with the knowledge of their predecessors so they don’t have to keep reinventing the wheel.” With the Primavera system already generating positive results, management is eager to take advantage of advanced capabilities. Loop is working on integrating the company’s proprietary inventory management system with the Primavera system so that when logistics or warehousing operators input data, the information will automatically go into the Primavera system. In the past, this information had to be manually keyed into spreadsheets, often leading to errors. Mining Historical Data Another feature on the horizon for AmeriCares is utilizing Primavera P6 Professional Project Management reporting capabilities. As the system begins to include more historical data, management soon will be able to draw on this information to conduct analysis that has not been possible before and create customized reports. For example, at the beginning of the shipment process, staff will be able to use historical data to more accurately estimate how long the approval process should take for a particular country. This could help ensure that food and medicine with limited shelf lives do not get stuck in customs or used beyond their expiration dates. The historical data in the Primavera system will also help AmeriCares with better planning year to year. The nonprofit’s staff has always put together a plan at the beginning of the year, but this has been very challenging simply because it is impossible to predict disasters. Now, management will be able to look at historical data and see trends and statistics as they set current objectives and prepare for future need. In addition, this historical data will provide AmeriCares management with the ability to review year-end data and compare actual project results with goals set at the beginning of the year—to see if desired outcomes were achieved and if there are areas that need improvement. It’s this type of information that is so valuable to donors. And, according to York, project management software can play a critical role in generating the data to help nonprofits sustain and grow. “It is important to invest in systems to help replicate, expand, and deliver services,” says York. “Project management software can help because it encourages nonprofits to examine program or service changes and how to manage moving forward.” Sears believes that AmeriCares donors will support the return on investment the organization will achieve with the Primavera solution. “It won’t be financial returns, but rather how many more people we can help for a given dollar or how much more quickly we can respond to a need,” says Sears. “I think donors are receptive to such arguments.” And for AmeriCares, it is all about the future and increasing results. The project management environment currently may be quite simple, but IT staff plans to expand the complexity and functionality as the organization grows in its knowledge of project management and the goals it wants to achieve. “As we use the system over time, we’ll continue to refine our best practices and accumulate more data,” says Sears. “It will advance our ability to make better data-driven decisions.”

  • Writing use cases for XML mapping scenarios between two different systems

    - by deepak_prn
    I am having some trouble writing use cases for XML mapping after a certain trigger invoked by the system. For example, one of the scenarios goes: the store cashier sells an item, the transaction data is sent to Data management system. Now, I am writing a functional design for the scenario which deals with mapping XML fields between our system and the data management system. Question : I was wondering if some one had to deal with writing use cases or extension use cases for mapping XML fields between two systems? (There is no XSLT involved) and if you used a table to represent the fields mapping (example is below) or any other visualization tool which does not break the bank ? I searched many questions on SO and here but nothing came close to my requirement.

  • What is Atomicity?

    - by James Jeffery
    I'm really struggling to find a concrete, easy to grasp, explanation of Atomicity. My understanding thus far is that to ensure an operation is atomic you wrap the critical code in a locker. But that's about as much as I actually understand. Definitions such as the one below make no sense to me at all. An operation during which a processor can simultaneously read a location and write it in the same bus operation. This prevents any other processor or I/O device from writing or reading memory until the operation is complete. Atomic implies indivisibility and irreducibility, so an atomic operation must be performed entirely or not performed at all. What does the last sentence mean? Is the term indivisibility relating to mathematics or something else? Sometimes the jargon with these topics confuse more than they teach.

  • How can I make sure that I'm actually learning how to program rather than simply learning the details of a language?

    - by Ryan
    I often hear that a real programmer can easily learn any language within a week. Languages are just tools for getting things done, I'm told. Programming is the ultimate skill that must be learned and mastered. How can I make sure that I'm actually learning how to program rather than simply learning the details of a language? And how can I develop programming skills that can be applied towards all languages instead of just one?

  • Does it help to be core programmer of a product (product meant for social good ) for getting into Ph. D. in top university in USA say top 20?

    - by Maddy.Shik
    Hey i am working upon a product as core developer which will be launched in USA market in few months if successful. Can this factor improve my chance to get Ph.D. in good university(say top 20 in US). Normally good universities like CMU, standford, MIT, Cornell are more interested in student's profile like research work, under graduate school etc. I am not passed out from very good university its ranked in top 20 of India only. Neither did i do research work till now. But being one of founding member of company and developing product for same, i want to know if this factor can help and to what extent. For university with ranking lower than 20 what matters most is GRE General score and GPA but i guess top university must be appreciating a person's real efforts.

  • How do you go about understanding the source code of an Open source project?

    - by Anirudh Vemula
    I am planning to contribute code through patches to some open source organisations to become more aware of open source development. I have chosen some organisations but when I download their source code, I don't seem to understand even a bit of it. How do I go about understanding their source code? I tried going through resolving a bug but finding the place in the source code where the bug is present is also difficult when you have no idea about how the code is structured and implemented. I need help on this so I can start working on an open source code.

  • What's a nice explanation for pointers?

    - by Macneil
    In your own studies (on your own, or for a class) did you have an "ah ha" moment when you finally, really understood pointers? Do you have an explanation you use for beginner programmers that seems particularly effective? For example, when beginners first encounter pointers in C, they might just add &s and *s until it compiles (as I myself once did). Maybe it was a picture, or a really well motivated example, that made pointers "click" for you or your student. What was it, and what did you try before that didn't seem to work? Were any topics prerequisites (e.g. structs, or arrays)? In other words, what was necessary to understand the meaning of &s and *, when you could use them with confidence? Learning the syntax and terminology or the use cases isn't enough, at some point the idea needs to be internalized. Update: I really like the answers so far; please keep them coming. There are a lot of great perspectives here, but I think many are good explanations/slogans for ourselves after we've internalized the concept. I'm looking for the detailed contexts and circumstances when it dawned on you. For example: I only somewhat understood pointers syntactically in C. I heard two of my friends explaining pointers to another friend, who asked why a struct was passed with a pointer. The first friend talked about how it needed to be referenced and modified, but it was just a short comment from the other friend where it hit me: "It's also more efficient." Passing 4 bytes instead of 16 bytes was the final conceptual shift I needed.

  • What are some recommended video lectures for a non-CS student to prepare for the GRE CS subject test?

    - by aristos
    Well the title kinda explains all there is to explain. I'm a non-cs student and was preparing to apply PhD programs in applied mathematics. But for my senior thesis I've been reading lots of machine learning and pattern recognition literature and enjoying it a lot. I've taken lots of courses with statistics and stochastics content, which I think, would help me if I get accepted to a program with ML focus, but there are only two CS courses -introduction to programming- in my transcript and therefore I decided to take the CS subject test to increase my chances. Which courses do you think would be most essential to have a good result from CS subject test? I'm thinking of watching video lectures of them, so do you have any recommendations?

  • I'm having trouble learning

    - by Gavin Sapp
    I'm only 13 but i'm genuinely interested in CS and would really like it if I could actually accomplish it. I've read books on C++ and C#, but ALL of them are the same!! They all say "Ok so since you have no prior knowledge in this what so ever, write a snippet that will do this and then make a GUI and then throw it into the Priafdhsu hfad then add the program and then program your own compiler to do some stuff". It's really getting annoying. I've payed near $40 (via Paypal) on ebooks that supposedly taught people to program with no prior knowledge. ALL OF THEM EXPECT ME TO ALREADY KNOW THE LANGUAGE. Is there something that I'm missing or am I suppose to be born with the property of CS? I would very much appreciate it if someone could explain this to me or possibly refer me to a tutorial on Programming Theory that starts from below ground zero as I have know knowledge in CS at all.
