  • Announcing Oracle Environmental Accounting and Reporting

    - by Theresa Hickman
    Oracle just launched a new product called Oracle Environmental Accounting and Reporting designed to help company’s track and report their greenhouse emissions at the operational level.  Companies around the world are facing increasing pressure to improve their energy efficiency and reduce waste in their operations. Also, new worldwide greenhouse gas legislation is putting added pressure on companies to report the impact of their emissions and energy usage on the environment. Today, companies undergo extensive and expensive data audits to maintain a ledger of up-to-date emissions factors that compare figures on an annual basis. Existing “ad hoc” approaches utilizing manual or niche solutions have a high operational cost and weak data security and audit-ability. The ideal solution is to embed environmental usage within the mainstream business operations, such as recording energy usage at the time of invoice entry, and then report on those results. This is precisely what Oracle Environmental Accounting and Reporting is designed to do. You can now capture environmental data either electronically or manually; convert that to greenhouse gas emissions; comply with mandatory and voluntary greenhouse gas reporting schemes; and identify opportunities for CO2 emissions and cost reductions.   Oracle recently acquired the intellectual property for this solution which works with both Oracle E-Business Suite Release 12 and JD Edwards EnterpriseOne Release 9.0. For more information, visit Oracle Environmental Accounting and Reporting.

  • PASS Location fixed for the next 2 years - Are they listening?

    - by simonsabin
    I've just received the PASS connector newsletter with details of the decision of where to locate the next summits. To me it shows you how you can spin statistics they way you want to. I am very suprised by the numbers 81% said that they would like an east coast event. The spin is that "When we look at responses from only 2008 and 2009 Summit attendees (our most successful ones by far), the number who want a future Summit outside of Seattle drops to 69%." Wow the number drops thats bad. We must stay in Seattle then. My take however is that 69% of those willing to travel to Seattle want an event NOT in Seattle. Doesn't that suggest that people would like an event not in Seattle. I appreciate the comment about the launch years however 2012 isn't going to be a launch year because they need to get SQL out of the door before then to meet the 3 year software assurance cycle. So sticking 2012 in Seattle is IMHO a bad decision. It might keep the cost down for the PASS org, Microsoft and the attendees that live near Seattle but does it keep the cost down for the rest of the SQL Community? They do mention a possibility of an event on the East Coast and I do hope that its not just lip service. Flights for me to the East coast look ~30% cheaper than to Seattle and I've never been to the East Coast. Come on PASS show you are listening to the community.

  • How do you compare job offers from companies in different countries?

    - by Danny Tuppeny
    This isn't really a programmer-specific question, but I'm not sure of a more appropriate place, and I think the users of this site are best able to answer the question in the context of programmers. Relocating to the US seems fairly common in the programming industry. I live in the UK, and maybe one day, I might do it too. So, if that day comes - how would you go about comparing job offers? Benefits are fairly easy to compare, but given the differences in cost of living, how would you go about comparing salaries and the quality of living you'll have? In a country where the cost of living is lower, you might be able to accept a lower salary (based on exchange rate) and still have the same quality of living. But what can you do to ensure this? In some cases, you may even take a "pay rise" in terms of exchange rate, but end up far worse off. How can you compare job offers across different countries to get an idea of the salary you would need in order to not feel you've gone "backwards"?

  • A project idea I've got...

    - by Mr Teeth
    Hi, Next year I will be doing a final year project at Uni. I've already thought of one and was wondering what you guys think of it. I want to create a University Information Search for prospective students who are trying to look for an affordable University to attend. It will depend on the student's family income and the grades they get. They enter in those two parameters (and some more) and it comes up with a list of suitable Unis based on their criteria. This is not about the price of tution fee. It's mostly to do with the cost of living. Stuff like: Rent (if living in a private flat). Student Accomadation. Cost of traveling to your home and back (for holidays). ...and some other stuff stuff I haven't thought about yet. It'll mostly be GUI driven with some textual information. I'm also thinking of using it as a website interface. What do you guys think? Can I program something like this Java? If there's any holes you see in my idea please tell me.

  • Customer retention - why most companies have it wrong

    - by Michel Adar
    At least in the US market it is quite common for service companies to offer an initially discounted price to new customers. While this may attract new customers and robe customers from competitors, it is my argument that it is a bad strategy for the company. This strategy gives an incentive to change companies and a disincentive to stay with the company. From the point of view of the customer, after 6 months of being a customer the company rewards the loyalty by raising the price. A better strategy would be to reward customers for staying with the company. For example, by lowering the cost by 5% every year (compound discount so it does never get to zero). This is a very rational thing to do for the company. Acquiring new customers and setting up their service is expensive, new customers also tend to use more of the common resources like customer service channels. It is probably true for most companies that the cost of providing service to a customer of 10 years is lower than providing the same service in the first year of a customer's tenure. It is only logical to pass these savings to the customer. From the customer point of view, the competition would have to offer something very attractive, whether in terms of price or service, in order for the customer to switch. Such a policy would give an advantage to the first mover, but would probably force the competitors to follow suit. Overall, I would expect that this would reduce the mobility in the market, increase loyalty, increase the investment of companies in loyal customers and ultimately, increase competition for providing a better service. Competitors may even try to break the scheme by offering customers the porting of their tenure, but that would not work that well because it would disenchant existing customers and would be costly, assuming that it is costlier to serve a customer through installation and first year. What do you think? Is this better than using "save offers" to retain flip-floppers?

  • The Oracle Platform

    - by Naresh Persaud
    Today’s enterprises typically create identity management infrastructures using ad-hoc, multiple point solutions. Relying on point solutions introduces complexity and high cost of ownership leading many organizations to rethink this approach. In a recent worldwide study of 160 companies conducted by Aberdeen Research, there was a discernible shift in this trend as businesses are now looking to move away from the point solution approach from multiple vendors and adopt an integrated platform approach. By deploying a comprehensive identity and access management strategy using a single platform, companies are saving as much as 48% in IT costs, while reducing audit deficiencies by nearly 35%. According to Aberdeen's research, choosing an integrated suite or “platform” of solutions for Identity Management from a single vendor can have many advantages over choosing “point solutions” from multiple vendors. The Oracle Identity Management Platform is uniquely designed to offer several compelling benefits to our customers.  Shared Services: Instead of separate solutions for - Administration, Authentication, Authorization, Audit and so on–  Oracle Identity Management offers a set of share services that allows these services to be consumed by each component in the stack and by developers of new applications  Actionable Intelligence: The most compelling benefit of the Oracle platform is ” Actionable intelligence” which means if there is a compliance violation, the same platform can fix it. And If a user is logging in from an un-trusted device or we detect an attack and act proactively on that information. Suite Interoperability: With the oracle platform the components all connect and integrated with each other. So if an organization purchase the platform for provisioning and wants to manage access, then the same platform can offer access management which leads to cost savings. Extensible and Configurable: With point solutions – you typically get limited ability to extend the tool to address custom requirements. But with the Oracle platform all of the components have a common way to extend the UI and behavior Find out more about the Oracle Platform approach in this presentation.

  • Business Intelligence (BI) Defined

    CIO.com defines Business Intelligence (BI) as a generic reference to a collection of applications that are used to analyze raw organizational data. Typical BI activities include data mining, online analytical processing, querying and reporting. They further explain that the primary reason why a company would utilize BI is to make their more data accessible. The more accessible data is to the users the faster they can identify ways to reduce business cost, discover new business opportunities, and react quickly to adjust prices based on current supply and demand. One area in which a hospital system could use BI derived from a data warehouse can be seen in the Emergency Room (ER) in regards to the number of doctors and nurse they have working during a full moon for each ER location. In order determine this BI needs to determine a trend in the number of patients seen on a full moon, further more they also need to determine the optimal number of staff members working during a full moon be determining the number of employees to patients ration needed to meet standard patient times and also be the most cost effective for the hospital.  This will allow the hospital system to estimate the number of potential patients they will have on the next full moon and adjust their staff schedules accordingly to ensure that patient care is not affected in any way do the influx or lack of influx of patients during this time while also ensuring that they are only working the minimum number of employees to ensure that they still making a profit. Another area where a hospital system could use BI data regards their orders paced to drug and medical supply companies. BI could define trends in prescriptions given to patients, this information could be used for ordering new supplies and forecasting the amount of medicine each hospital needs to keep on site at a given time. For example, a hospital might want to stock up on materials need to set bones in a cast prior to the summer because their BI indicates that a majority of broken bones occur during the summer due to children being out of school and they have more free time.

  • Managing products on a an ecommerce site [closed]

    - by John
    I've had a site that sells widgets for many years. I do not inventory my widgets, but the cost of adding them to the site and makings sure the site is current is becoming cost prohibitive. Here are the facts: I sell a single class of widget. I have about 50,000 widgets on my site. I have about 100 vendors that create and dropship the products when they get an order from me via email. Each vendor carries from 50 to 5000 types of widgets. Vendors all have websites with images and descriptions of their products. Each widget is produced in limited supply and usually sell out in 1-5 years. Prices of the widget often go up, sometimes more than 50% before they sell out. My vendors aren't very tech sophisticated. They have websites with their products, but most can't supply an api or database dump. Their websites usually display retail prices to the public, but I login or refer to a price list (usually excel) for wholesale prices. As it stands now, I hire local people to add and describe each widget to our website. It usually takes a person 4 minutes to add a widget to the site. This doesn't include moving to a new vendor. I feel like the upload/edit process is as good as it can get via a form/website. The problem is that it is getting very expensive to upload and keep the widget inventory current. I often get orders for something after it's sold out from the vendor or the price is wrong. This seems like it would be a problem in many industries. Can anyone suggest the cheapest way to upload inventory and ensure prices are current from my vendors? I'm assuming it will involve outsourcing, but I would like ideas on how to setup the compensation model.

  • algorithm for Virtual Machine(VM) Consolidation in Cloud

    - by devansh dalal
    PROBLEM: We have N physical machines(PMs) each with ram Ri, cpu Ci and a set of currently scheduled VMs each with ram requirement ri and ci respectively Moving(Migrating) any VM from one PM to other has a cost associated which depends on its ram ri. A PM with no VMs is shut down to save power. Our target is to minimize the weighted sum of (N,migration cost) by migrating some VMs i.e. minimize the number of working PMs as well as not to degrade the service level due to excessive migrations. My Approach: Brute Force approach is choosing the minimum loaded PM and try to fit its VMs to other PMs by First Fit Decreasing algorithm or we can select the victim PMs and target PMs based on their loading level and shut down victims if possible by moving their VMs to targets. I tried this Greedy approach on the Data of Baadal(IIT-D cloud) but It isn't giving promising results. I have also tried to study the Ant colony optimization for dynamic VM consolidating but was unable to understand very much. I used the links. http://dumas.ccsd.cnrs.fr/docs/00/72/52/15/PDF/Esnault.pdf http://hal.archives-ouvertes.fr/docs/00/72/38/56/PDF/RR-8032.pdf Would anyone please explain the solution or suggest any new approach for better performance soon. Thanks in advance.

  • Pathfinding with MicroPather : costs calculations with sectors and portals

    - by Adan
    Hello, I'm considering using micropather to help me with pathfinding. I'm not using a discrete map : I'm working in 2d with sectors and portales. However, I'm just wondering what is the best way to compute costs with this library in this context. Just to be more clear about geometrical shapes I'm using : sectors are basically convex polygons, and portals are segments that lies on sector's edge. Micropather exposes a pure virtual Graph class that you must inherate and overrides 3 functions. I understand how pathfinding works, so there's no problem in overriding those functions. Right now, my implementation give me results, i.e I'm able to find a path in my map, but I'm not sure I'm using an optimal solution. For the AdjacentCost method : I just take the distance between sector's centers as the cost. I think a better solution should be to use the portal between the two sectors, compute its center, and then the cost should be : distance( sector A center, portal center ) + distance ( sector B center, portal center ). I'm pretty sure the approximation I'm using with just sector's center is enough for most cases, but maybe with thin and long sectors that are perpendicular, this approximation could mislead the A* algorithm. For the LeastCostEstimate method : I just take the midpoint of the two sectors. So, as you understand, I'm always working with sectors' centers, and it's working fine. And I'm pretty sure there's a better way to work. Any suggestions or feedbacks? Thanks in advance!

  • Combining pathfinding with global AI objectives

    - by V_Programmer
    I'm making a turn-based strategy game using Java and LibGDX. Now I want to code the AI. I haven't written the AI code yet. I've simply designed it. The AI will have two components, one focused in tactics and resource management (create troops, determine who have strategical advantage, detect important objectives, etc) and a individual component, focused in assign the work to each unit, examine its possibilites and move the unit. Now I'm facing an important problem. The map where the action take place is a grid-based map. Each terrain has different movement cost. I read about pathfinding and I think A* is a very good option to determine a good route between two points. However, imagine I have an unit with movement = 5 (i.e, it can move 5 tiles of movement cost = 1). My tactical AI has found an objective at a distance d = 20 tiles (Manhattan distance) from my unit. My problem is the following: the unit won't be able to reach the objective in one turn. So the AI will have to store a list of position and execute them in various turns. I don't know how to solve this. PS. In my unit code, I have a list called "selectionMarks" which stores all the possible places where the unit can go in this turn. This places are calculed recursively using a "getSelectionMarks" function. Any help is appreciated :D

  • WebCenter at Oracle Day Toronto

    - by Lance Shaw
    The Oracle Day event took place in Toronto yesterday at the Hyatt Regency Hotel downtown.  Attendance was excellent and it was standing room only at the keynote sessions.   Anytime the venue has to bring in chairs to handle the overflow crowd, you know there is a lot of interest! This year, WebCenter was featured prominently as part of the Fusion Middleware session track.  What was interesting to see was just how many customers are interested in consolidating and simplifying their existing infrastructure.  So many companies are still struggling with information silos such as file shares, SharePoint Sites and a myriad of departmental or process-centric repositories.  Naturally, these get more and more expensive to manage over time so there is a high level of interest in reducing the size, scope and cost of this infrastructure.  When companies see how they can use Fusion Middleware and related technologies to integrate with WebCenter Content, Imaging and other solutions to centralize content delivery across business applications, they quickly realize that there are significant cost savings to be had. Oracle Day Events are happening all over the world and there is likely going to be one near you.  To check out the full list and to register, visit the Event page here.  It is a great way to not only hear about WebCenter and how it can be used to your advantage, but also a great way to learn about the broader set of related products in the Fusion Middleware portfolio that are available to extend and enhance the power of your particular business solutions. If you cannot make it, or missed the event in your area, be sure to visit our new WebCenter Content page with a variety of informative assets all in one simple location.  It's a new page designed to provide you with easy access to customer stories, videos, whitepapers, webcasts and more.  We hope you find it valuable!

  • The Mac Tax

    - by Robert May
    One of our users was having difficulties with their mac and using some web software.  I decided to go peruse the landscape and see how much of a premium people were paying for their macs.  I priced out a Dell and a Mac from their websites.  I tried to get them as close to the same configuration, from a hardware standpoint, as I could.  I found the following: Apple Macbook Pro   Dell XPS 17 There are several important differences in the hardware: The mac doesn’t have a blueray player, but the dell does. The mac has a slightly slower processor. The mac claims to have a better battery, but doesn’t list the specifics, so there’s no way to tell. The mac doesn’t list the video card stats, so there’s no way to tell how comparable they are, but they’re probably close. The mac doesn’t come with any additional software.  No iWorks, iPhoto, etc.  They were left to their default of None, so arguably, the Dell is more functional out of the box. Other than changing the hardware specs to be close, all other configuration options were left at their default. So riddle me this, Batman:  Why do people buy Macs?  I have several dev buddies that own them, but I can’t justify the cost.  First, most of them load bootcamp and/or parallels at extra cost to run windows 7 and windows apps.  The hardware isn’t as good.  The price is almost twice as expensive. How do you justify the premium price? Technorati Tags: General

  • Is there really anything to gain with complex design? [duplicate]

    - by SB2055
    This question already has an answer here: What is enterprise software, exactly? 8 answers I've been working for a consulting firm for some time, with clients of various sizes, and I've seen web applications ranging in complexity from really simple: MVC Service Layer EF DB To really complex: MVC UoW DI / IoC Repository Service UI Tests Unit Tests Integration Tests But on both ends of the spectrum, the quality requirements are about the same. In simple projects, new devs / consultants can hop on, make changes, and contribute immediately, without having to wade through 6 layers of abstraction to understand what's going on, or risking misunderstanding some complex abstraction and costing down the line. In all cases, there was never a need to actually make code swappable or reusable - and the tests were never actually maintained past the first iteration because requirements changed, it was too time-consuming, deadlines, business pressure, etc etc. So if - in the end - testing and interfaces aren't used rapid development (read: cost-savings) is a priority the project's requirements will be changing a lot while in development ...would it be wrong to recommend a super-simple architecture, even to solve a complex problem, for an enterprise client? Is it complexity that defines enterprise solutions, or is it the reliability, # concurrent users, ease-of-maintenance, or all of the above? I know this is a very vague question, and any answer wouldn't apply to all cases, but I'm interested in hearing from devs / consultants that have been in the business for a while and that have worked with these varying degrees of complexity, to hear if the cool-but-expensive abstractions are worth the overall cost, at least while the project is in development.

  • Costs/profit of/when starting an indie company

    - by Jack
    In short, I want to start a game company. I do not have much coding experience (just basic understanding and ability to write basic programs), any graphics design experience, any audio mixing experience, or whatever else technical. However, I do have a lot of ideas, great analytical skills and a very logical approach to life. I do not have any friends who are even remotely technical (or creative in regards to games for that matter). So now that we've cleared that up, my question is this: how much, minimally, would it cost me to start such a company? I know that a game could be developed in under half a year, which means it would have to operate for half a year prior, and that's assuming that the people working on the first project do their jobs good, don't leave game breaking bugs, a bunch of minor bugs, etc.. So how much would it cost me, and what would be the likely profit in half a year? I'm looking at minimal costs here, as to do it, I would have to sell my current apartment and buy a new, smaller one, pay taxes, and likely move to US/CA/UK to be closer to technologically advanced people (and be able to speak the language of course). EDIT: I'm looking at a small project for starters, not a huge AAA title.

  • Web dev/programmer with 4.5 yrs experience. Better for career: self-study or master's degree? [closed]

    - by Anonymous Programmer
    I'm a 28 year-old web developer/programmer with 4.5 years of experience, and I'm looking to jump-start my career. I'm trying to decide between self-study and a 1-year master's program in CS at a top school. I'm currently making 65K in a high cost-of-living area that is NOT a hot spot for technology firms. I code almost exclusively in Ruby/Rails, PHP/CodeIgniter, SQL, and JavaScript. I've slowly gained proficiency with Git. Roughly half the time I am architecting/coding, and half the time I am pounding out HTML/CSS for static brochureware sites. I'd like to make more more money while doing more challenging/interesting work, but I don't know where to start. I have an excellent academic record (math major with many CS credits, 3.9+ GPA), GRE scores, and recommendations, so I am confident that I could be admitted to a great CS master's program. On the other hand, there is the tuition and opportunity cost to consider. I feel like there are a number of practical languages/tools/skills worth knowing that I could teach myself - shell scripting, .NET, Python, Node.js, MongoDB, natural language processing techniques, etc. That said, it's one thing to read about a subject and another thing to have experience with it, which structured coursework provides. So, on to the concrete questions: What programming skills/knowledge should I develop to increase my earning potential and make me competitive for more interesting jobs? Will a master's degree in CS from a top school help me develop the above skills/knowledge, and if so, is it preferable to self-study (possibly for other reasons, e.g., the degree's value as a credential)?

  • Location Change Salary Differences [closed]

    - by GameDev
    DISCLAIMER: I know that this might be a "regional" question but I'm also asking for help as far as what resources to use to determine my decision. I'm currently talking to a recruiter for a game developer in the SF Bay area. I work in a relatively low-cost area in the south. I really want to get into game development but my current career is general web development. I'm very interested in taking the job, but my concern is that the amount they're willing to pay might be a relative pay cut. Here are some factors: It's not an entry-level position, the title is Senior Software Engineer. I have 5+ years of experience. The calculators online tell me that I should be expecting around 2x my current pay rate(http://www.bestplaces.net/col/). My current pay is in the mid $60k/yr, so that's like 120-130k. The recruiter told me at my experience level I can expect about $90-100/yr, and that those cost of living calculators were way off. The benefits will definitely be better, it's much larger company (help with commuting, catered meals, etc). But is the recruiter trying to give me a snow job on the pay scale, or is that a reasonable change from a smallish town in the south to somewhere in the SF bay area? How can I find this out? Glassdoor and Payscale seem to say "senior software developers" in that area make around 110 in median salary, but Payscale says it's closer to $135k, that range seems pretty large.

  • How "commercially savvy" should software developers be? [closed]

    - by mattnz
    I have been watching answers to many questions on this site, and have come to the conclusion that commercial pragmatism does not factor into many software development discussions. As a result, I seriously wonder at the commercial skills within the industry, specifically the ability to deliver projects on time and to a budget. I see no indication from the site that commercially successful project delivery is a serious concern, yet the industry has a reputation for poor performance in this. Rarely, if ever, does the cost of time factor into discussions. I have never seen concepts such as opportunity cost, time to market, competitive advantage or cash flow mentioned, let alone discussed in technical answers to questions. How can you answer virtually any question without understanding the commercial background on which it is asked? Even Open source projects have a need to operate efficiently and deploy their limited resources to providing the most value for effort. Typically small start-ups have cash flow issues that outweigh longevity concerns, yet they are typically still advised to build for a future they probably won’t have if they do. Is it fair to say that these problems are solely the Managers and Project managers to solve, or are we, as developers, also responsible for ensuring successful on time, within budget delivery of projects, even if those budgets do not allow use to achieve engineering excellence?

  • Efficient algorithm for Virtual Machine(VM) Consolidation in Cloud

    - by devansh dalal
    PROBLEM: We have N physical machines(PMs) each with ram Ri, cpu Ci and a set of currently scheduled VMs each with ram requirement ri and ci respectively Moving(Migrating) any VM from one PM to other has a cost associated which depends on its ram ri. A PM with no VMs is shut down to save power. Our target is to minimize the weighted sum of (N,migration cost) by migrating some VMs i.e. minimize the number of working PMs as well as not to degrade the service level due to excessive migrations. My Approach: Brute Force approach is choosing the minimum loaded PM and try to fit its VMs to other PMs by First Fit Decreasing algorithm or we can select the victim PMs and target PMs based on their loading level and shut down victims if possible by moving their VMs to targets. I tried this Greedy approach on the Data of Baadal(IIT-D cloud) but It isn't giving promising results. I have also tried to study the Ant colony optimization for dynamic VM consolidating but was unable to understand very much. I used the links. http://dumas.ccsd.cnrs.fr/docs/00/72/52/15/PDF/Esnault.pdf http://hal.archives-ouvertes.fr/docs/00/72/38/56/PDF/RR-8032.pdf Would anyone please clarify the solution or suggest any new approach/resources for better performance. I am basically searching for the algorithms not the physical optimizations and I also know that many commercial organizations have provided these solution but I just wanted to know more the underlying algorithms. Thanks in advance.

  • What's is the point of PImpl pattern while we can use interface for same purpose in C++?

    - by ZijingWu
    I see a lot of source code which using PIMPL idiom in C++. I assume Its purposes are hidden the private data/type/implementation, so it can resolve dependence, and then reduce compile time and header include issue. But interface class in C++ also have this capability, it can also used to hidden data/type and implementation. And to hidden let the caller just see the interface when create object, we can add an factory method in it declaration in interface header. The comparison is: Cost: The interface way cost is lower, because you doesn't even need to repeat the public wrapper function implementation void Bar::doWork() { return m_impl->doWork(); }, you just need to define the signature in the interface. Well understand: The interface technology is more well understand by every C++ developer. Performance: Interface way performance not worse than PIMPL idiom, both an extra memory access. I assume the performance is same. Following is the pseudocode code to illustrate my question: // Forward declaration can help you avoid include BarImpl header, and those included in BarImpl header. class BarImpl; class Bar { public: // public functions void doWork(); private: // You doesn't need to compile Bar.cpp after change the implementation in BarImpl.cpp BarImpl* m_impl; }; The same purpose can be implement using interface: // Bar.h class IBar { public: virtual ~IBar(){} // public functions virtual void doWork() = 0; }; // to only expose the interface instead of class name to caller IBar* createObject(); So what's the point of PIMPL?
