  • Who should be the architect in an agile project?

    - by woni
    We are developing the agile way for a few months now and I have some troubles understanding the agile manifesto as interpreted by my colleagues. The project we are developing is a framework for future projects and will be reused many times in the next years. Code is only written to fulfill the needs of the current user story. The product owner tells us what to do, but not how to do it. What would be right, in my opinion, because he is not implicitly a programmer. The project advanced and in my eyes it messed up a little bit. After I recognized an assembly that was responsible for 3 concerns (IoC-Container, communication layer and project internal things), I tried to address this to my colleagues. They answered that this would be the result of applying YAGNI, because know one told them to respect that functionalities have to be split up in different assemblies for further use. In my opinion no one has to tell us that we should respect the Separation of Concerns principle. On the other side, they mentioned to prefer YAGNI over SoC because it is less effort to implement and therefore faster and cheaper. We had changing requirements a lot at the beginning of the project and ended up in endless refactoring sessions, because to much has to be adapted. Is it better to make such rather simple design decisions up front, even there is no need in the current situation, or do we have to change a lot in the later progress of the project?

  • Connect to NFS on availability

    - by berkes
    What would be a good way to automatically mount an NFS when it gets/is available? I have the following: Media server at home, running Ubuntu, 10.10 with GUI *) Laptop often at home, often on the road or at clients. Ubuntu 10.10 with GUI. What I'd like is my laptop connecting to the nfs (or any other mountable networked filesystem) so that Banshee sees all the music, new podcast-entries (and video) from that media-server. I already have firefly (mt-daapd) running, which works, but is flakey on both server-side and client-side. But its biggest downside, is that I cannot easily fix metadata on files on the media-server this way. DAAP is read-only by design. I can mount nfs manually, through a sudo mount /media/nfsmultimedia/. I am not looking for a manual, or howto on setting up a NFS client and server. Merely a way to have this more transparently working. Obviously I'd like the NFS to be unmounted if the network is no longer available (i.e. when I open my laptop-lid on my clients buro). It may be, that an NFS is not suited for this, in that case, I'd love to hear other options. :) *) Actually: I also have a fileserver, backupserver and webserver to which I'd like to connect in a somewhat similar way. Right now I connect to these over SSH, using gvfs.

  • Why doesn't it seem to be any development in the field of 3D VR gear, especially with regard to gaming?

    - by neuviemeporte
    I remember that way back around 1995, there was this big craze with VR in the media, a whole bunch of (mostly mediocre) games labeled as "virtual-reality-interactive-movie (...)" were published. If I recall correctly, the first 3D VR helmet was called VFX-1 and was sold bundled with Descent and some dedicated joystick. I never owned one, and I read just one review which was mostly enthusiastic, but pointed to some weak points, like the eyes getting tired after an hour or so of playing. Then the whole thing basically flickered down and died. I suppose the main reason it wasn't successful was that the hardware of the day was not powerful enough, the VR gear's design wasn't perfected to make it comfortable and natural to use, and the companies that made it failed to market it successfully. What I can't understand is why isn't there any development in the field today. There is some vr-ish hardware mostly targeted at the consoles (Kinect, Wii remote, TrackIR), but all projects of creating some 3d head-mounted display system seem to be in early infancy, appear once in a trade show somewhere and aren't heard of again. I think it could work great with head tracking and some of today's shooters, flight sims (trackIR is nice but the movement scale translation is awkward) and other games with an FPP POV. Is there any technological reason why decent vr headgear can't be made today, or is it just that nobody really cares/everyone is scared to repeat the '90s failure?

  • Why does my player stop when stepping onto a new tile?

    - by user220631
    Me and my friend are creating a game from scratch. He is in charge of art design and I am in charge of coding. I have done well so far with the code, but I have a collision detection problem when the character moves right: Once the player moves right, whenever a new block is encountered, the player stops. I don't know if this is a problem with collision or the player but I can't work around it. Here is the collision code: this.IsColliding = function(obj) { if(this.X > obj.X + obj.Width) return false; else if(this.X + this.Width < obj.X) return false; else if(this.Y > obj.Y + obj.Height) return false; else if(this.Y + this.Height < obj.Y) return false; else return true; } I also wanted to see if there as a way to make the player collide with the bottom of the block and the right side of the block instead of running through it.

  • Multiplayer online game engine/pipeline

    - by Slav
    I am implementing online multiplayer game where client must be written in AS3 (Flash) to embed game into browser and server in C++ (abstract part of which is already written and used with other games). Networking models may differ from each other, but currently I'm looking toward game's logic run on both client and server parts but they're written on different languages while it's not the main problem. My previous game (pretty big one - was implemented with efforts of ~5 programmers in 1.5 years) was mainly "written" within electronic tables as structured objects with implemented inheritance: was written standalone tool which generated AS3 and C++ (languages of platforms to which the game was published) using specified electronic tables file (.xls or .ods). That file contained ~50 tables with ~50 rows and ~50 columns each and was mainly written by game designers which do not know any programming languages. But that game was single-player. Having declared problem with my currently implementing MMO, I'm looking toward some vast pipeline, where will be resolved such problems like: game objects descriptions (which starships exist within game, how much HP they have, how fast move, what damage deal...) actions descriptions (what players or NPCs can do: attack each other, collect resources, build structures, move, teleport, cast spells) - actions are transmitted through server between clients influences (what happens when specified action applied on specified object, e.i "Ship A attacked Ship B: field "HP" of Ship B reduced by amount of field "damage" of Ship A" Influences can be much more difficult, yes, e.i. "damage is twice it's size when Ship has =5 allies around him in a 200 units range during night" and so on. If to be able to write such logic within some "design document" it will be easily possible to: let designers to do their job without programmer's intervention or any bug-prone programming validate described logic transfer (transform, convert) to any programming language where it will be executed Did somebody worked on something like that? Is there some tools/engines/pipelines which concernes with it? How to handle all of this problems simultaneously in a best way or do I properly imagine my tasks and problems to myself?

  • How to monetize and protect a engine's and its framework's copyrights and patents?

    - by Arthur Wulf White
    I created a game engine that handles: Rendering levels with 2d textured curved surfaces Collisions with curved surfaces Animationn paths on and navigation in 2d-sapce I have also made a framework for: Procedural organic level generation with round surfaces Level editing Light weight sprite design The engine and framework are written in AS3 and I am in the process of translating the code into HaXe to better support other platforms. I am also interested in adding Animated curved platforms More advanced level editing features Currently, I have a part time job and any time I spend on this engine is either taken out of my limited free time (I'm a student working to support myself through school) or out my time working at my job. I really believe this engine can make life much easier for people designing Tower Defence games, Shooters and and Platformers while also possibly improving their results. It could also support RTS, RPGs and racing games very well. It continains original algorithms that could be used for procedural generation of organic round and smooth levels. The algorithms I used are new and are not available in any other level editor I've seen. In order to constantly improve the Engine and have it tested thoroughly I think the best route is releasing it to the public. What are the best ways to benefit myself and others with my new framework? I want to have some lisence, allowing me to share the framework and still benefit from it. Any advice would be appreciated. This issue has been on my mind a lot this year. I am hoping to find a solution that will bring me some relief. I am thinking of designing three sample games, releasing them and starting a kickstarter, any advice and thoughts on the matter would be valuable. My goal is like Markus von Broady suggested, to get people involved in developing the engine and let people use it for games for either a symbolic fee or for free and charge for support. That or use some form of croud sourcing. Do I need to hire a lawyer to get some sort of legal document to protect my work?

  • Three New Videos on Social Development

    - by Bob Rhubart
    By now it should be clear to even the most tenacious Luddite that the social media phenomenon is no mere fad. Those ubiquitous icons for Facebook and Twitter and other social networks are little beacons of disruptive change signalling yet again that the 20th century is over, dude. And that presents an opportunity for software developers with the necessary insight and expertise to tap into and expand social platforms for forward-thinking organizations. If you're a developer and you're interested in exploiting these emerging opportunities you'll want to check out three new videos that focus on software development for social platforms. Developing with Facebook: An Introduction to Social Design James Pearce, Facebook's head of Mobile Developer Relations, provides an overview of the Facebook platform and the underlying APIs that are available to the developer community. Building on the LinkedIn Platform: Content Amplified Adam Trachtenberg, Director of LinkedIn's Developer Network, discusses how you can make it simple for a professional audience to discover and distribute your content on LinkedIn. Emergence of the Social Enterprise Roland Smart, Oracle's VP of Social Marketing, shares Oracle’s vision for the social-enabled enterprise and highlights the role developers will play in the next phase of enterprise development. OTN has also created the Oracle Social Developer Community, a new Facebook page devoted to the promotion of community conversation and resources to support Social Developers. If you're working on a social development project, visit the page and tell us about it.

  • what languages are good selling points on resume? [closed]

    - by Thomas Galvin
    I have a good amount of experience with C# and Java at the moment but after education and whatnot I wish to be able in more than just 2 high-level, comparatively limited languages, and from what I've seen languages like C(++) or PHP are in demand at the moment. I've thought about learning the following: C. Very standard, lightweight and available on everything. However very old and mostly procedural. C++. Standard like C but I've read in some places that it encourages bad programming design and use of dodgy libraries - but similar things have been said about C too so I'll take that with a grain of salt. D. Quite new but looks promising, but will it be relevant or applicable in the future though? PHP. With the internet becoming ever more important I think this might be the one to go with, but the code itself isn't very intuitive. CoffeeScript (or plain JavaScript). With Microsoft's new idea of HTML5+JS for everything under the sun this doesn't look like a bad choice. However things do change and I wish to be primarily a software dev, not web dev. So out of the above list, or any others that you could suggest, what would you say I should begin to focus on? What is your opinion on staying with C#?

  • Why does working processors harder use more electrical power?

    - by GazTheDestroyer
    Back in the mists of time when I started coding, at least as far as I'm aware, processors all used a fixed amount of power. There was no such thing as a processor being "idle". These days there are all sorts of technologies for reducing power usage when the processor is not very busy, mostly by dynamically reducing the clock rate. My question is why does running at a lower clock rate use less power? My mental picture of a processor is of a reference voltage (say 5V) representing a binary 1, and 0V representing 0. Therefore I tend to think of of a constant 5V being applied across the entire chip, with the various logic gates disconnecting this voltage when "off", meaning a constant amount of power is being used. The rate at which these gates are turned on and off seems to have no relation to the power used. I have no doubt this is a hopelessly naive picture, but I am no electrical engineer. Can someone explain what's really going on with frequency scaling, and how it saves power. Are there any other ways that a processor uses more or less power depending on state? eg Does it use more power if more gates are open? How are mobile / low power processors different from their desktop cousins? Are they just simpler (less transistors?), or is there some other fundamental design difference?

  • SQL Saturday #89 in Atlanta!

    - by Most Valuable Yak (Rob Volk)
    (Yeah yeah, technically it's in Alpharetta, but it's close enough.) Saturday…Saturday….Saturday…. September 17th.  TWO THOUSAND ELEVEN! OK, it's not a tractor pull, but it's even better:  FREE SQL SERVER TRAINING!  They have a bunch of great speakers lined up, and for some reason, me.  (Protip: be good friends with the program committee, have sufficient bribe funds, and if all else fails, lots of alcohol, drugs and a camera.  Ba-ZING!  You too can speak at SQL Saturday!) I will be presenting Revenge: The SQL! in a new and improved SQL Saturday themed presentation.  Actually, it's the same ol' presentation, I just updated the slide theme to match the new SQL Saturday website design.  (Yeah guys, thanks for changing that a month ago.  So much for coasting on the old format.) Of course, you have your choice of three other SQL Saturdays in other cities that day, but come on, you really want to go to this one. #sqlsat89 #sqlsaturday #sqlkilt #sqlpass

  • BusEnum2 and a Minor Bug Fix

    - by Kate Moss' Open Space
    The default root bus driver, BusEnum, enumerate and active drivers one by one in synchronized manner. It is not only slowing the boot time but in the even if any of driver's init function (XXX_init) get hanged, the whole system won't boot at all. There is a sample of enhanced root bus driver, BusEnum2, on the http://msdn.microsoft.com/en-us/library/dd187254.aspx The page provides the sample code and the detail explanation of the design concept. With multi-threaded BusEnum2 on CE7 with SMP enabled system, the scalability is even more significant. Since you have more than one processor and it can load drivers in parallel! Everything looks good so far, except to there is a small bug in the sample code. Fortunately, it is easy to fix. But hard to trace if you ever enc outer it! The BUSENUM2 flag only defined in BUSENUM2\BUSDEF\sources but not in BUSENUM2\BUSENUM\sources. The DeviceFolder is implemented in BUSENUM2\BUSDEF but the instance is created in BUSENUM2\BUSENUM\busenum.cpp, so the result is it allocates less memory than actual need.   Add   CDEFINES=$(CDEFINES) -DBUSENUM2   into BUSENUM2\BUSENUM\sources and the problem fixed!

  • Best Architecture for ASP.NET WebForms Application

    - by stack man
    I have written an ASP.NET WebForms portal for a client. The project has kind of evolved rather than being properly planned and structured from the beginning. Consequently, all the code is mashed together within the same project and without any layers. The client is now happy with the functionality, so I would like to refactor the code such that I will be confident about releasing the project. As there seems to be many differing ways to design the architecture, I would like some opinions about the best approach to take. FUNCTIONALITY The portal allows administrators to configure HTML templates. Other associated "partners" will be able to display these templates by adding IFrame code to their site. Within these templates, customers can register and purchase products. An API has been implemented using WCF allowing external companies to interface with the system also. An Admin section allows Administrators to configure various functionality and view reports for each partner. The system sends out invoices and email notifications to customers. CURRENT ARCHITECTURE It is currently using EF4 to read/write to the database. The EF objects are used directly within the aspx files. This has facilitated rapid development while I have been writing the site but it is probably unacceptable to keep it like that as it is tightly coupling the db with the UI. Specific business logic has been added to partial classes of the EF objects. QUESTIONS The goal of refactoring will be to make the site scalable, easily maintainable and secure. 1) What kind of architecture would be best for this? Please describe what should be in each layer, whether I should use DTO's / POCO / Active Record pattern etc. 2) Is there a robust way to auto-generate DTO's / BOs so that any future enhancements will be simple to implement despite the extra layers? 3) Would it be beneficial to convert the project from WebForms to MVC?

  • Is it better to specialize in a single field I like, or expand into other fields to broaden my horizons?

    - by Oak
    This is a dilemma about which I have been thinking for quite a while. I'm a graduate student and my topics of interest are programming language design, code analysis, compilation, etc. So far, this field has been very interesting and rewarding for me, so I was thinking about finding a job in that field and continuing to specialize in it. I feel like it's a relatively solid field which won't "get out of style" anytime soon. I've always thought that in such complex fields it's better to be a real expert than just another guy who superficially understand what the experts are talking about. On the other hand, I feel that by specializing this way I really limit my future option. I have always been a strong believer in multidisciplinary approaches to problems. Maybe I should go search for a general programming job in which I could gain experience in other fields, as well as occasionally apply my favorite field for solving problems. Specializing in only one or two fields can prevent me from thinking outside the box and cause stagnation. I would really like to hear more opinions about this choice. The truth is I'm already leaning towards one of the choices, so basic psychology says nothing will change my mind, but I would still love to hear some feedback.

  • Knowing state of game in real time

    - by evthim
    I'm trying to code a tic tac toe game in java and I need help figuring out how to efficiently and without freezing the program check if someone won the game. I'm only in the design stages now, I haven't started programming anything but I'm wondering how would I know at all times the state of the game and exactly when someone wins? Response to MarkR: (note: had to place comment here, it was too long for comment section) It's not a homework problem, I'm trying to get more practice programming GUI's which I've only done once as a freshman in my second introductory programming course. I understand I'll have a 2D array. I plan to have a 2D integer array where x would equal 1 and o would equal 0. However, won't it take too much time if I check after every move if someone won the game? Is there a way or a data structure or algorithm I can use so that the program will know the state (when I say state I mean not just knowing every position on the board, the int array will take care of that, I mean knowing that user 1 will win if he places x on this block) of the game at all times and thus can know automatically when someone won?

  • If you have the full spec done, what is left for the developer to do?

    - by Leeho
    I'm working in a small company, started as a developer and coded pieces of a big system being provided with detailed specs. Over five years I moved towards analyst position. I know how existing parts of the system are build, so when we need a new subsystem I know how to connect it to the existing things. So I analyse requirements for a new subsystem to be done, design a new module, then code main parts of it. After that me with my colleagues who are proper analysts write detailed specs for junior developers to finish the module. The problem is that I don't see a new job for myself. I realise that jack-of-all-trades isn't considered to be good, and I don't see getting myself a job exactly like this in a big company. But if I look for a developer job, then I would be somewhat like junior again? Because if I will be provided with detailed description of what software has to do, all that seems to be left for me is merely translating spec to the code, which is plain boring. But developer is considered to solve problems, so which problems are those supposed to be? Only pure technical problems I can imagine is performance optimization. So basically my question is - what problems developers are supposed to face and solve, if all decisions of how application should work to meet customers needs are considered to be an analyst job? What problems do you solve at work?

  • Oracle Worldwide Product Translation Group and Applications User Experience Working Together

    - by ultan o'broin
    The Applications User Experience (UX) Mobile team has been extending its ethnographic research to even more countries. Recently, the team conducted research in Sweden, and I am pleased to say I made the connection for the UX team with the Oracle's Worldwide Translation Product Group (WPTG) local (that is, in-country) language specialists. It struck me that WPTG's local market knowledge and insight that we heard about at an Oracle Usability Advisory Board meeting in the UK in 2011 would be very valuable to the UX efforts while, at the same time, UX could afford WPTG an opportunity to understand our design and development direction so that linguistic resources (terminology, style guides, translatability guidelines, and so on) for any translation of our mobile solutions could be prepared in advance. Brent White of the Mobile UX team takes notes as ethnography participant Capri Norman uses mobile technology to work in Stockholm. Pic credit: Oracle Applications UX. The UX team acknowledges Capri's kind permission to use this image. I'm told by Brent White of the Mobile UX team that the co-operation was a big success.  A WPTG Swedish language specialist joined a couple of ethnographic sessions, taking great notes and turning them around very fast for the UX team. And of course, a great local insight into Swedish culture and ways of working was provided too, along with some nice socializing!  More research in more countries is planned. Watch out for future blog posts and other communications about this great co-operation worldwide.

  • Mobile Web Framework that will only control rendering and page transitions

    - by rlemon
    I have been using jQueryMobile for a bit now, and there are some things I like about it and others I do not. First I will give a bit of background. I have a light weight mobile application that has a few configurations and 6 pages. Ideally I Would like to load all pages into the DOM (they interact with each other quite often and pages will be switched in the same frequency). The application will post for some JSON every n seconds and refresh the values on the page (yes it is primarily a information display app). with the jQuery Mobile framework the only real thing I like is how easy it is to have a standardized UI a crossed all devices and browsers, I'm really not using too much else out of the framework other than the basic page navigation (if you are familiar with the framework; a bare-bone multi-page design is all i need). Why I want to step away from jQueryMobile is how weighty it is. Not only do you need to include the mobile library, but also the base jQuery libraries. This I do not like because I'm not using jQuery anywhere else on the site. Any suggestions on light-weight mobile frameworks that have a similar rendering as jQueryMobile?

  • What's new at Oracle in Gamification?

    - by erikanollwebb
    It's been a crazy few weeks in Apps UX.  We are actively working on some gamification designs in now 4 different application product areas, as well as supporting some teams in other areas of Oracle.  Since that gets to be a pretty diverse group with a lot of resources and ideas, we've started a group in the Oracle Social Network on Gamification at Oracle.  That's limited to internal users at Oracle, but if you are interested in joining,  ping me directly for more information at [email protected]. We're planning another design jam like we did here at Oracle in May and at the Enterprise Gamification Forum in San Diego in September.  This time, we're taking the show to the UK, and hosting it with a group of customers on the Oracle Usability Advisory Board.  It should be a great event!   We're also actively designing some gamified flows which we'll be testing with users at the UKOUG to see what our customers think about some of our gamification ideas. We're looking at more feedback opportunities.  Internally, we surveyed 444 folks within Oracle about gamification and we'll be posting some of our findings on that here soon.  I'll be posting a blog on gamification for our customers at useableapps.oracle.com  in the next few weeks and I'll cross-post to here when it comes out.  So even though it's been quiet on this blog, we are busy and I'm hoping to push out more content in the next few weeks!  Would love to know what's most interesting to the folks reading so if there's something you especially want to see, feel free to comment or email me about it.

  • Part 4: Development Standards or How to share

    - by volker.eckardt(at)oracle.com
    Although we usually introduce the custom development part in EBS projects as “a small piece only” and “we will avoid as best as possible”, the development effort can be enormous and should therefore be well addressed by project standards. Any additional solution or additional software tool or product shall influence the custom development rules (by adding, removing or replacing sections). It is very common in EBS projects to create a so called “MD.030 Development Standards” document and put everything what’s related to development conventions into it. This document gets approval and will be shared among all developers. Later, additional sections have to be added, and usually the development lead is responsible for doing this. However, sometimes used development techniques are not documented properly, and therefore the development solutions deviate from each other, or from the initially agreed standards. My advice would be the following: keep the MD.030 as a base document, and add a Wiki on top. The “Development Wiki” covers the following: Collect input from every developer without updating the MD.030 directly Collect additional topics that might need further specification Allow a discussion about such topics by reviewing/updating the wiki directly Add also decisions or open questions right into it. In one of my own projects we were using this “Developer Wiki” quite extensive, and my experience is very positive. We had different sections in it, good cross references, but also additional material like code templates, links to external web pages etc. By using this wiki, the development standards became “owned” by the right group of people, the developers. They recognized that information sharing can improve the overall development quality, but will also reduce the workload on individuals. Finally, the wiki was much more accurate and helpful for the daily development work than our initial MD.030, and we all decided to retire the document completely. Summary: Information sharing in the development area is very important! The usual “MD.030 Development Standards“ is a good starting point, but should be combined with a “Development Wiki”, allowing everyone to address and discuss necessary improvements. A well-structured Wiki can replace the document in some sections completely. Side Note: The corresponding task in Oracle OUM (Oracle Unified Method) is DS.050 ‘Determine Design and Build Standards’ Volker

  • Avoid overwriting all the methods in the child class

    The context I am making a game in C++ using SFML. I have a class that controls what is displayed on the screen (manager on the image below). It has a list of all the things to draw like images, text, etc. To be able to store them in one list I created a Drawable class from which all the other drawable class inherit. The image below represents how I would organize each class. Drawable has a virtual method Draw that will be called by the manager. Image and Text overwrite this method. My problem is that I would like Image::draw method to work for Circle, Polygon, etc. since sf::CircleShape and sf::ConvexShape inherit from sf::Shape. I thought of two ways to do that. My first idea would be for Image to have a pointer on sf::Shape, and the subclasses would make it point onto their sf::CircleShape or sf::ConvexShape classes (Like on the image below). In the Polygon constructor I would write something like ptr_shape = &polygon_shape; This doesn't look very elegant because I have two variables that are, in fact, just one. My second idea is to store the sf::CircleShape and sf::ConvexShape inside the ptr_shape like ptr_shape = new sf::ConvexShape(...); and to use a function that is only in ConvexShape I would cast it like so ((sf::ConvexShape*)ptr_shape)->convex_method(); But that doesn't look very elegant either. I am not even sure I am allowed to do that. My question I added details about the whole thing because I thought that maybe my whole architecture was wrong. I would like to know how I could design my program to be safe without overwriting all the Image methods. I apologize if this question has already been asked; I have no idea what to google.

  • Easy to use JSON Web Service Hosts?

    - by Serguei Fedorov
    I saw this being used by someone in a college class once and cannot find anything that is analogous to it. I am not sure if this is the right place to ask about something like this, but hopefully I can get some direction. I want to write an app which uses web services that can obtain and push data back to the client apps. Right now I am gathering up the design and documentation of this app. Not having to code the web service myself would reduce development time by a lot; instead using an easy to setup web service that will be easy to setup and manage. Either XML based on JSON based is totally fine; though I would prefer JSON for its reduced overhead. Like I said I have seen this demonstrated before; you define the data structure to be stored and how it is treated. I cannot find the person who demonstrated this; hopefully maybe someone can suggest something? The service he used was free with a limited amount of requests allowed. EDIT: He was using an online service to do this not a script which is installed onto an existing web hosting account. Thank you!

  • What would be a good topic for research on "edge of multiple processors / computers programming" topic?

    - by Kabumbus
    This is a subjective discussion so we can express our dreams and hopes here. A "topic" must be like a task with point to have as end result a software poduct. A "topic" must be mainly about "Software engineering", "Algorithm and data structure concepts" and perhaps "Design patterns". I mean let us try to look what is not already there? What can be developed in fiew month and give a breakthrue / start a new leap / show somethig not realized before in science of f multiple computers programming? What i see is already there: LAN / wire and other infrastractural programms for connecting on device level MPI/ Bit torrent/Jabber protocols / APIs / servers for messaging on top Boost and analogs on evry OS in most languages for multithreading there are lots of CUDA like on computer frameworks for fast calculating on computers GPUs What I personally do not see out there is a crossplatform framework for multiple processes interaction. Meaning one that would allow easy creation of multyple processes running in paralell inside one hoster app on one machine. In level not harder than needed for threads creation (so no seprate server apps - just one lib doing it all) Is there ny such lib and what can you propose for research topic?

  • How to Assure an Effective Data Model

    As a general rule in my opinion the effectiveness of a data model can be directly related to the accuracy and complexity of a project’s requirements. For example there is no need to work on very detailed data models when the details surrounding a specific data model have not been defined or even clarified. Developing data models when the clarity of project requirements is limited tends to introduce designed issues because the proper details to create an effective data model are not even known. One way to avoid this issue is to create data models that correspond to the complexity of the existing project requirements so that when requirements are updated then new data models can be created based any new discoveries regarding requirements on a fine grain level.  This allows for data models to be composed of general entities to be created initially when a project’s requirements are very vague and then the entities are refined as new and more substantial requirements are defined or redefined. This promotes communication amongst all stakeholders within a project as they go through the process of defining and finalizing project requirements.In addition, here are some general tips that can be applied to projects in regards to data modeling.Initially model all data generally and slowly reactor the data model as new requirements and business constraints are applied to a project.Ensure that data modelers have the proper tools and training they need to design a data model accurately.Create a common location for all project documents so that everyone will be able to review a project’s data models along with any other project documentation.All data models should follow a clear naming schema that tells readers the intended purpose for the data and how it is going to be applied within a project.
