  • How to visualize the design of a program in order to communicate it to others

    - by Joris Meys
    I am (re-)designing some packages for R, and I am currently working out the necessary functions, objects, both internal and for the interface with the user. I have documented the individual functions and objects. So I have the description of all the little parts. Now I need to give an overview of how the parts fit together. The scheme of the motor so to say. I've started with making some flowchart-like graphs in Visio, but that quickly became a clumsy and useless collection of boxes, arrrows and-what-not. So hence the question: Is there specific software you can use for vizualizing the design of your program If so, care to share some tips on how to do this most efficiently If not, how do other designers create the scheme of their programs and communicate that to others? Edit: I am NOT asking how to explain complex processes to somebody, nor asking how to illustrate programming logic. I am asking how to communicate the design of a program/package, i.e.: the objects (with key features and representation if possible) the related functions (with arguments and function if possible) the interrelation between the functions at the interface and the internal functions (I'm talking about an extension package for a scripting language, keep that in mind) So something like this : But better. This is (part of) the interrelations between functions in the old package that I'm now redesigning for obvious reasons :-) PS : I made that graph myself, using code extraction tools on the source and feeding the interrelation matrix to yEd Graph Editor.

  • How do you explain to an "agile" team that they still need to plan the software they write?

    - by user23157
    This week at work I got agiled yet again. Having gone through the standard agile, TDD, shared ownership, ad hoc development methodology of never planning anything beyond a few user stories on a piece of card, verbally chewing the cud over the technicallities of a 3rd party integration ad nauseam without ever doing any real thinking or due dilligence and architecturally coupling all production code to the first test that comes into anyone's head for the past few months we reach the end of a release cycle and lo and behold the main externally visible feature that we have been developing is too slow to use, buggy, becoming labyrinthinly complex and completely inflexible. During this process "spikes" were done but never documented and not a single architectural design was ever produced (there was no FS, so what the hell eh, if you don't know what you are developing, how can you plan or research it?) - the project passed from pair to pair, each of whom only ever focused on a single user story at a time and well the result was inevitable. To resolve this I went off the radar, went (the dreaded) waterfall, planned, coded and basically didn't swap off the pair and tried as much as I could to work alone - focusing on solid architecture and specifications rather than unit tests which will come later once everything is pinned down. The code is now much better and is actually totally usable, flexible and fast. Certain people seem to have really resented me doing this and have gone out of their way to sabotage my efforts (possibly unconsciously) because it goes against the holy process of agile. So how do you, as a developer, explain to the team that it is not "un-agile" to plan their work, and how do you fit planning into the agile process? (I'm not talking about the IPM; I'm talking about sitting down with a problem and sketching out an end-to-end design that says how a problem should be solved in sufficient detail that anyone who works on the problem knows what architecture and patterns they should be using and where the new code should integrate into existing code)

  • Impact on SEO of adding categories/tags in front of the HTML title [closed]

    - by Mad Scientist
    Possible Duplicate: Does the order of keywords matter in a page title? All StackExchange sites add the most-used tag of a question in front of the HTML title for SEO purposes. On Stackoverflow for example this is usually the programming language, so you end up with a title like python - How do I do X? This has obviously an enourmous benefit on SEO as the programming language is an extremely important keyword that is very often omitted from the title. Now, my question is for the cases where the tag isn't an important keyword missing from the title, but just a category. So on Biology.SE for example one would have questions like biochemistry - How does protein X interact with Y? or on Skeptics medical science - Do vaccines cause autism? Those tags are usually not part of the search terms, they serve to categorize the content but users don't use those tags in their searches. How harmful is adding tags that are not used in searches in terms of SEO? Is there any hard data on the impact this practise might have on SEO? The negative aspects I can imagine, but have no data to show that it is actually a problem are: I heard that search engines dislike keyword stuffing and this might trigger some defense mechanisms against that It's a practise associated with less reputable sites, a keyword in front that doesn't fit the actual title well might look suspicious to some users. It wastes precious space in the title shown in search results.

  • Perfomance of 8 bit operations on 64 bit architechture

    - by wobbily_col
    I am usually a Python / Database programmer, and I am considering using C for a problem. I have a set of sequences, 8 characters long with 4 possible characters. My problem involves combining sets of these sequences and filtering which sets match a criteria. The combinations of 5 run into billions of rows and takes around an hour to run. So I can represent each sequence as 2 bytes. If I am working on a 64 bit architechture will I gain any advantage by keeping these data structures as 2 bytes when I generate the combinations, or will I be as well storing them as 8 bytes / double ? (64 bit = 8 x 8) If I am on a 64 bit architecture, all registers will be 64 bit, so in terms of operations that shouldn´t be any faster (please correct me if I am wrong). Will I gain anything from the smaller storage requirements - can I fit more combinations in memory, or will they all take up 64 bits anyway? And finally, am I likley to gain anything coding in C. I have a first version, which stores the sequence as a small int in a MySQL database. It then self joins the tabe to itself a number of times in order to generate all the possible combinations. The performance is acceptable, depending on how many combinations are generated. I assume the database must involve some overhead.

  • Can JSON be made easily and safely editable by the non-technical Excel crowd?

    - by glitch
    I'm looking for a data storage format that's very intuitive and easy to edit. It should be ideally targeted towards the same crowd as Excel. At the same time I would like the data structure to be a tree. Ideally this would be JSON, since it offers both the tree aspect and allows for more interesting constructs like arrays. That and parsing libraries for JSON are ubiquitous, so I don't have to reinvent the wheel. The problem is that, at least with a non-specialized text editor, JSON is a giant pain to edit for a non-technical user. I'm thinking along the lines of someone who might have used Excel in the past, but never a real text editor. Someone who might not be comfortable with the idea of preserving JSON syntax by hand. Are there data formats out there that would fit this profile? I'd very much prefer this to be a JSON actually, but then it would require a solid editing tool that would hide the underlying implementation from the user. Think Excel and how it abstracts CSV syntax from the user. The reason I'm looking for something like this is because the team has been working with pretty hierarchical data for a while now and we've hit the limits of how easy it is to represent in simple CSVs without having to create complex rules for how represent hierarchy semantics from each row. Any suggestions?

  • NVIDIA Graphics - resolution problems with new 12.04 LTS installation

    - by Daveisuser56810
    I've been trying to install Ubuntu 12.04 LTS on my desktop most of the day. The desktop uses a NVIDIA GEFORCE 9800 (GT I think) graphics card. I am unable to set the correct resolution (1680 x 1050) for the display. The first problem I had was that of the "Black Screen" during install. I overcame this by utilising the "nomodeset" switch on the install options (once I'd found how to do that). The second problem of course was the "Black screen" following the first reboot. Once again this was overcome by using "nomodeset", this time by "editing" the GRUB. This gave me a resolution of 1280x768 which, the Displays GUI allowed me to change to 1280x720 (appears to fit on screen). I then tried to install the NVIDIA drivers. 1) using additional drivers 2) manually by downloading driver and installing in root As soon as NVIDIA drivers are installed - resolution become restricted to 640x480 (max). At this resolution Ubuntu GUI is not usable as most screens are larger than the display. Removing the NVIDIA driver and removing the XORG.CONF file does not lift this restriction. I have tried most things that I have found and that were vaguely intelligible, but nothing appears to get me closer to a resolution of 1680x1050. UPDATE: reinstalled Ubuntu 12-04 and used the "NoModeSet" in the Grub to restore the resolution to 1280x720, which is at least usable. Will live with this for now.

  • As a developer, how do I learn sales? [closed]

    - by Dan Abramov
    I quit the company I was working for to pursuit an opportunity as a startup, and I believe in our product. I'm sure it's going to be great if we attract some customers first to keep going. (I don't want funding.) Our product is targeted at private schools and courses, and helps organize the mess other LMSs introduce. The problem is, our team is basically just me and I have very little idea about sales and marketing. I can do reasonably good copywriting but I'm sure I can do better—and being nervous or too techy in a real world conversation with the client doesn't help. I want to get better, in fact, a lot better at negotiating with clients and pitching my product. I did look for some “sales articles” on the web, and a lot of what I found is plain bullshit on SEO-engineered websites promoting books or $5000 courses. What I need instead is a developer's perspective on how to sale a product you think is great. What are typical programmer's mistakes and misconceptions about sales, and how to avoid them? How do you evolve into a reasonably great salesman? I can't believe it's in the mindset and unlearnable. Your own experience, combined with great articles available on the web is most welcome. To Future Readers The question got closed because it is not a good fit for this site. I found some helpful tips in a similar question asked on a sister StackExchange site about startups: I'm a terrible salesperson. What can I do about it?

  • Website Hosting/Registration [closed]

    - by Ricko M
    Possible Duplicate: How to find web hosting that meets my requirements? I am planning to launch a website down soon. I wanted to know what solutions are available for hosting and registration. Starting with domain registration. Any site you have used/preferred ? I am considering either godaddy or 123reg. Does it even make any difference which you choose? Is there any fine print i need to worry about. I am based in UK , not sure if that helps in resolving any issues if encountered. Does my hosting need to be done at the site i purchased my registration? If not , will there be any transfer fees if i change my hosting? Can I just register the name now and worry about hosting later? At the moment, I plan to have it up and running using either some sort of a tool or a template and perhaps put the bells and whistles down the line. I understand 123 has its own builder tool available, There are a few solutions suggested like wordpress,drupal & jhoomla... I am a C++ developer , not a web programmer, but I do feel the need to open the hood up and make changes if i see fit. So I guess I am looking for a solution where I can easily drag-drop widgets I need and when the time comes customize it. Which CMS would you recommend. Extras: What extras do you need to get , I was suggested to get hold of whois privacy to keep the spambots away, anything else you guys would recommend I keep my eyes open before I sign the dotted line.

  • Does your organization still use the term "screens" to describe a user interface?

    - by bit-twiddler
    I have been in the field long enough to remember when the term "screen" entered our lexicon. As difficult as it is to believe, the early systems on which I worked had no user interface (UI), that is, unless one counts a keypunch machine and job listings as a user interface. These systems ran as "card image" production jobs back in a day when being a computer operator required a reasonably deep understanding of how computers worked. Flashing forward to today: I cringe every time I hear a systems practitioner use the term "screen." The metaphor no longer fits the medium. The term somewhat fit back when the user dialog consumed 100% of available monitor real estate; however, the term lost its relevance the moment we moved to windowed environments. With the above said, does your organization still use the term "screens" to describe an application's UI? Has anyone successfully purged the term from an organization? For those who do not use the term to describe UI dialog elements, what term do you use in place of “screen.”

  • What .NET objects should I use to create a cookie based session in MVC?

    - by makerofthings7
    I'm writing a custom password reset application that uses a validation technique that doesn't fit cleanly with ASP.NET Membership Provider's challenge questions. Namely I need to invoke a workflow and collect information from the end user (backup phone number, email address) after the user logs in using a custom form. The only way I know to create a cookie-based session (without too much "innovation" on my part) is to use WIF. What other standard objects can I use with ASP.NET MVC to create an authenticated session that works with non-windows user stores? Ideally I can store "role" or claim information in the session object such as "admin", "departmentXadmin", "normalUser", or "restrictedUser" The workflow would look like this: User logs in with username and password If the username and pw are correct a (stateless) cookie based session is created The user gets redirected to a HTML form that allows them to enter their backup phone number (for SMS dual factor), or validate it if already set. The user can then change their password using the form provided The "forgot password" would look like this User requests OTP code to be sent to the phone User logs in using username and OTP If the OTP is valid and not expired then create a cookie based session and redirect to a form that allows password reset Show password reset form, and process results.

  • Why are embedded device apps still written in C/C++? Why not Java programming language?

    - by hinkmond
    At the recent Black Hat 2014 conference in Sin City, the Black Hatters were focusing on Embedded Devices and IoT. You know? Make your networked-toaster burn your bread 10,000 miles away, over the Web for grins and giggles. Well, apparently the Black Hatters say it can be done pretty easily these days, which is scary. See: Securing Embedded Devices & IoT Here's a quote: All these devices are still written in C and C++. The challenges associated with developing securely in these languages have been fought for nearly two decades. "You often hear people say, 'Well, why don't we just get rid of the C and C++ language if it's so problematic. Why don't we just write everything in C# or Java, or something that is a little safer to develop in?'," DeMott says. Gah! Why are all these IoT devices still using C/C++? Of course they should be using Java SE Embedded technology! It's a natural fit to use for better security on embedded devices. Or, I guess, developers really don't mind if their networked-toasters do char their breakfast. If it can be burned, it will be... That's what I say. Unless they use Java. Hinkmond

  • Raspberry Pi Now Shipping with 512MB RAM; Still Only $35

    - by Jason Fitzpatrick
    Fans of the tiny Raspberry Pi will be pleased to hear the new version of their Model B board now ships with 512MB of RAM (up from the previous 256MB). The best part about the upgrade? The price point stays at $35 a board. From the official Raspberry Pi blog: One of the most common suggestions we’ve heard since launch is that we should produce a more expensive “Model C” version of Raspberry Pi with extra RAM. This would be useful for people who want to use the Pi as a general-purpose computer, with multiple large applications running concurrently, and would enable some interesting embedded use cases (particularly using Java) which are slightly too heavyweight to fit comfortably in 256MB. The downside of this suggestion for us is that we’re very attached to $35 as our highest price point. With this in mind, we’re pleased to announce that from today all Model B Raspberry Pis will ship with 512MB of RAM as standard. If you have an outstanding order with either distributor, you will receive the upgraded device in place of the 256MB version you ordered. Units should start arriving in customers’ hands today, and we will be making a firmware upgrade available in the next couple of days to enable access to the additional memory. We’re excited to get our hands on a new board and try out Raspbmc with that extra RAM. HTG Explains: What is the Windows Page File and Should You Disable It?

  • Application toolkits like QT versus traditional game/multimedia libraries like SFML

    - by Aaron
    I currently intend to use SFML for my next game project. I'll need a substantial GUI though (RPG/strategy-type) so I'll either have to implement my own or try to find an appropriate third party library, which seem to boil down to CEGUI, libRocket, and GWEN. At the same time, I do not anticipate doing that many advanced graphical effects. My game will be 2D and primarily sprite-based with some sprite animations. I've recently discovered that QT applications can have their appearance styled so that they don't have to look like plain OS apps. Given that, I am beginning to consider QT a valid alternative to SFML. I wouldn't have to implement the GUI functionality I'd need, and I may not be taking advantage of SFML's lower-level access anyway. The only drawbacks I can think of immediately are the learning curve for QT and figuring out how to fit game logic inside such a framework after getting used to the input/update/render loop of traditional game libraries. When would an application toolkit like QT be more appropriate for a game than a traditional game or multimedia library like SFML?

  • Dealing with bad/incomplete/unclear specifications?

    - by eagerMoose
    I'm working on a project where our dev team gets the specifications from the business part of the company. Both the business management and the IT management require estimates and deadline projections, as they should. The good thing is that estimates are mostly made by the actual developers who get to do the required features. The bad thing is that the specifications are usually either too simple (it turns out you're left with a lot of question marks over your head because a lot of information seems to be missing) or too complex(up to the point that you can't even visualize where everything would "fit" in the app). More often than not, the business part of the specs are either incomplete or unaware of what can and can't be done (given the previously implemented business logic). Dev team is given about a day per new spec to give an estimate and we do try to clear uncertainties, usually by meeting up with whoever did the spec. Most of the times it turns out that spec writers haven't really thought everything through, and it's usually only when we start designing and developing that we end up in trouble, as a lot of the spec seems to have holes. How do you deal with this? Are you generous on estimates in advance?

  • Old Lock Retrofitted for Wireless and Key-free Entry

    - by Jason Fitzpatrick
    What do you do if the old key your landlord gave you is poor fit for your apartment’s lock? If you’re the geeky sort, you build a wireless unlocking module to do the work for you. Instructables user Rybitski writes: The key to my apartment never worked quite right because it is a copy of a copy of a copy. I am fairly certain that the dead bolt is original to the building and the property manager seems to have lost the original key years ago. As a result unlocking the door was always a pain. Changing the lock wasn’t an option, but eliminating the need to use a key was. To that end, he built the device seen in the video above. An Arduino Uno drives a servo which in turn opens the deadbolt. The whole thing is controlled by a simple wireless key fob. Hit up the link below for the full build guide including code.

  • Programming habits, patterns, and standards that have developed out of appeal to tradition/by mistake? [closed]

    - by user828584
    Being self-taught, the vast majority of what I know about programming has come from reading other peoples' code on websites like this. I'm starting to wonder if I've developed bad or otherwise pointless habits from other people, or even just made invalid assumptions. For example, in javascript, void 0 is used in a lot of places, and until I saw this, I just assumed it was necessary and that 0 had some significance. Also, the http header, referer is misspelled but hasn't been changed because it would break a lot of applications. Also mentioned in Code Complete 2: The architecture should describe the motivations for all major decisions. Be wary of “we’ve always done it that way” justifications. One story goes that Beth wanted to cook a pot roast according to an award-winning pot roast recipe handed down in her husband’s family. Her husband, Abdul, said that his mother had taught him to sprinkle it with salt and pepper, cut both ends off, put it in the pan, cover it, and cook it. Beth asked, “Why do you cut both ends off?” Abdul said, “I don’t know. I’ve always done it that way. Let me ask my mother.” He called her, and she said, “I don’t know. I’ve always done it that way. Let me ask your grandmother.” She called his grandmother, who said, “I don’t know why you do it that way. I did it that way because it was too big to fit in my pan.” What are some other examples of this?

  • How to refactor when all your development is on branches?

    - by Mark
    At my company, all of our development (bug fixes and new features) is done on separate branches. When it's complete, we send it off to QA who tests it on that branch, and when they give us the green light, we merge it into our main branch. This could take anywhere between a day and a year. If we try to squeeze any refactoring in on a branch, we don't know how long it will be "out" for, so it can cause many conflicts when it's merged back in. For example, let's say I want to rename a function because the feature I'm working on is making heavy use of this function, and I found that it's name doesn't really fit its purpose (again, this is just an example). So I go around and find every usage of this function, and rename them all to its new name, and everything works perfectly, so I send it off to QA. Meanwhile, new development is happening, and my renamed function doesn't exist on any of the branches that are being forked off main. When my issue gets merged back in, they're all going to break. Is there any way of dealing with this? It's not like management will ever approve a refactor-only issue so it has to be squeezed in with other work. It can't be developed directly on main because all changes have to go through QA and no one wants to be the jerk that broke main so that he could do a little bit of non-essential refactoring.

  • First Project a big one, How much should we charge?

    - by confuzzled
    Two of my cousins and I started a freelance computer repair/web design business just to make some money on the side during college, and received our first major web design project about three weeks ago. Now we've created websites before, but it was mostly for family businesses and have never really charged money, and most of the websites have been static, and don't really require a CMS. This project, however, was a big one (for us anyways). We created a news site that had several categories, we created the banners, we created a classifieds page (not a web app just something static that they control). Several links, a few graphical assets, CSS drop down menu, RSS feed from a different news site, weather, all the normal stuff you would find on a regular news site. On top of that we put in all the usual Joomla stuff (search, Jcomments, Jslide pictures, JCE, etc.). Then we uploaded the first 10 articles they gave us, and we are going to train them how to use Joomla. Now, at first we decided for 700 dollars. I assumed they just wanted a simple blog like website where they can upload articles. But then we had a meeting, and they asked for a lot more. Note: we did not hard code the template from scratch, but customized the gantry framework to fit their needs. We did code quite a bit however. I estimate that we put in about 50-60 hours in total. I'm wondering if 700 dollars is a bit low, this price is definitely not set in stone. Please keep in mind that this is our first project, and we are newbies, please be kind. Thank You!

  • Relation between developers and clients

    - by guiman
    Hi everyone, i've been facing a situation at work and i would like to share it with you and tell me: Did you had to do it to? Should a developer be in direct contact wit the client? Or there should be an "adapter" guy that translates client needs in pseudo formal requirements understandable to us? I'm currently working in a small company that its taking care of implementing lots of systems, most of them for goverment institutions, in witch it generally means taking software developted 20 years ago and refurbish them so fit up-to-date needs. The clients generally are very used to them and tend to discourage change (they are in their 50s 60s give or take, so not technologie-friendly in general). As you can imagine, dev-team in most cases starts taking care of relation with clients, generating the documentation needed in this cases (CU usually), assisting to weekly meets to see improvements with clients. As for experience, this is a gold mine for me, because gives a nice perspective on all the aspects of software development, but also some problems rise because, if developers come from mars then client are from venus. So there is a fine gap on the vocabulary/experience/capability-to-interpret-needs that generates an noice in the communication, and some times affecting the final product.

  • Do support sites like Stack Overflow upset the paid-support open source model?

    - by ajax81
    In order to stay relevant in the marketplace, I'm researching new business models for my software company. The open source model with paid support seems like a good fit for our product, but I have concerns about whether or not a paid support model is viable in an era where top-notch help is readily available for free on sites like those in the Stack Exchange network. Case in point -- I moved my employees to Ubuntu last year because I didn't want to pay for Win 7 licenses and new hardware (plus, the mono platform was highly attractive). My staff had no Linux experience, but were able to achieve relative competency in about 120 days with the help of AskUbuntu, Stack Overflow, and a few "For Dummies" books. We did employ an Ubuntu consultant for 7 days to provide training and support, but beyond that spent $0.00 on any kind of paid expertise. In regards to my due diligence, I ran a 3 month beta of the freemium-paid-support model with one of our smaller customers, and achieved mediocre results. I'd like to think its because our software is so stable and easy to use that the customer didn't need much paid support, but I suspect that they circumvented the terms of our SLA in the same manner that we did with the move to Ubuntu. Does anyone out there has any thoughts, advice, or experience relevant to the move I'm considering? What worked, what didn't, etc?

  • Uses of persistent data structures in non-functional languages

    - by Ray Toal
    Languages that are purely functional or near-purely functional benefit from persistent data structures because they are immutable and fit well with the stateless style of functional programming. But from time to time we see libraries of persistent data structures for (state-based, OOP) languages like Java. A claim often heard in favor of persistent data structures is that because they are immutable, they are thread-safe. However, the reason that persistent data structures are thread-safe is that if one thread were to "add" an element to a persistent collection, the operation returns a new collection like the original but with the element added. Other threads therefore see the original collection. The two collections share a lot of internal state, of course -- that's why these persistent structures are efficient. But since different threads see different states of data, it would seem that persistent data structures are not in themselves sufficient to handle scenarios where one thread makes a change that is visible to other threads. For this, it seems we must use devices such as atoms, references, software transactional memory, or even classic locks and synchronization mechanisms. Why then, is the immutability of PDSs touted as something beneficial for "thread safety"? Are there any real examples where PDSs help in synchronization, or solving concurrency problems? Or are PDSs simply a way to provide a stateless interface to an object in support of a functional programming style?

    Gartner, Inc. has named Oracle a Leader in its latest “Magic Quadrant for Web Content Management.” Gartner’s Magic Quadrants position vendors within a particular quadrant based on their completeness of vision and their ability to execute on that vision. According to Gartner, “WCM plays an increasingly important role in business performance. It has become the central point of coordination for initiatives involving the enterprise's online presence, and these initiatives have become more sophisticated and more important to enterprises' business strategies. Thus, WCM is key for organizations wishing to execute a strategy of OCO (online channel optimization) that embraces areas such as customer experience management, e-commerce, digital marketing, multichannel marketing and website consolidation.” Gartner continued, “Leaders should drive market transformation. Leaders have the highest combined scores for Ability to Execute and Completeness of Vision. They are doing well and are prepared for the future with a clear vision and a thorough appreciation of the broader context of OCO. They have strong channel partners, a presence in multiple regions, consistent financial performance, broad platform support and good customer support. In addition, they dominate in one or more technologies or vertical markets. Leaders are aware of the ecosystem in which their offerings need to fit. Leaders can: demonstrate enterprise deployments’ offer integration with other business applications and content repositories; provide a vertical-process or horizontal-solution focus.” Oracle WebCenter, the engagement platform powering exceptional experiences for customers, employees and partners, connects people and information by bringing together the most complete portfolio of portal, Web experience management, content, social, and collaboration technologies into a single integrated product suite. Oracle WebCenter also provides the foundation for Oracle Fusion Middleware and Oracle Fusion Applications to deliver a next-generation user experience.  To see the latest reports, webcasts and demonstrations about Oracle's web experience management solution, Oracle WebCenter Sites, please visit our Connected Customer Experience Resource Center.

  • Picking a suitable resolution for a modern low-res game?

    - by MrKatSwordfish
    I'm working on a 2D game project right now (using SFML+OpenGL and C++) and I'm trying to figure out how to go about choosing a resolution. I want my game to have a pixel resolution that is around that of classic '16bit' era consoles like the Super Nintendo or Neo Geo. However, I'd also like to have my game fit the 16:9 aspect ratio that most modern PC monitors use. Finally I'd like to be able to include an option for running full screen. I know that I could create my own low-res 16:9 resolution that is more-or-less around the size of SNES or NeoGeo games. However, the problem seems to be that doing so would leave me with a non-standard resolution that my monitor would not be able to support in fullscreen mode. For example, if i divide the common 16:9 resolution 1920x1080 by 4, I would get a 16:9 resolution that is relatively close to the resolution used by 16bit era games; 480x270. That would be fine in a windowed mode, but I don't think that it would be supported in fullscreen mode. How can I choose a resolution that suits my needs? Can I use something like 480x270? If so, how would I go about getting fullscreen mode to work with such a non-standard resolution? (I'm guessing OpenGL/SFML might have a way of up-scaling...but..)

  • Oracle E-Business Suite is Helping to Save Lives at the National Marrow Donor Program

    - by Di Seghposs
    To improve the management of its life-saving operations, the National Marrow Donor Program recently modernized its financial and procurement operations by upgrading to Oracle E-Business Suite 12.1.   As the global leader in bone marrow and umbilical cord blood transplants, the NMDP manages a complex ecosystem of donor, patient, hospital, and biological data. “Maintaining accurate data and having an efficient matching process is essential, particularly as our global database of bone marrow patients grows and donor lists expand,” says Bruce Schmaltz, director of finance/controller. “We rely on the Oracle E-Business Suite to ensure our procurement and financial management processes meet the highest standards, enabling our growing non-profit to work swiftly and efficiently to help improve and save lives.” As the non-profit organization and its registry grew larger, NMDP needed a modern platform to store and integrate its financial information and complicated procurement process. It selected Oracle E-Business Suite for its ability to fit seamlessly into NMDP’s enterprise architecture. NMDP initially implemented Oracle E-Business Suite release 12 by leveraging Oracle Business Accelerators, which are rapid implementation tools and templates that help reduce implementation time and costs. With Oracle Financial Management and Oracle Procurement, NMDP has streamlined back-office processes and integrated its procure-to-pay business processes by leveraging industry leading accounts payable, accounts receivable, and general ledger modules. NMDP is currently rolling out Oracle Hyperion Performance Management applications and plans to implement Oracle Order Management and Oracle Advanced Pricing by the end of 2012.
